                                     The Company

              Virtual Open  Network  Environment  Corporation  ("V-ONE"  or  the
     "Company")  develops,  markets,  and  licenses  a  comprehensive  suite  of
     network  security  products  that  enable  businesses  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  authentication,  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 standards.    In  addition, the  Company's
     products  enable  businesses  to  deploy and  scale  their  solutions  from
     small,  single-site  networks  to  large,  multi-site   environments.   The
     Company's   customers  include  key  participants in   the   financial  and
     information  services  markets,  as  well  as   U.S.  government  agencies,
     including   BancOne   Corp.  ("BancOne"),  BayBank   Systems,  Inc.,   Fuji
     Capital Markets Corporation, GE  Information Services,  Inc. ("GEIS"), VISA
     International and the  National  Security Agency ("NSA").

              Organizations are increasing their dependence  on public networks,
     such as  the  Internet,  and  private enterprise  networks  using  Internet
     protocols  ("intranets") as  a cost-effective  means  to expand  enterprise
     networks,  engage   in  electronic   commerce,  and  increase   information

                                          2

     exchange.  The  demand for  security in  computer networks  is expected  to
     grow significantly  as a result  of the increased  use of the Internet  and
     intranets.  The  Yankee Group, a  market research firm,  indicated that  it
     expects  the  market for  information security  products and  services will
     grow at  a 70%  compound  annual rate  from $395  million in  1995 to  $5.6
     billion in the year 2000.  

              As  businesses  increase their  use  of  the  Internet and  deploy
     intranets, there  is  a  growing  need  for  comprehensive, enterprise-wide
     network security solutions.  To protect an organization's data, network and
     computer systems, a  comprehensive network security solution  requires five
     elements:  identification  and authentication,  integrity, non-repudiation,
     authorization,  and encryption.   To date,  network security solutions have
     focused on single function or point products that  address one or a limited
     number  of these security  elements. These  products  were designed  with a
     specific  function  or  objective;  however,  few  were  designed  to  meet
     all of the needs of enterprise-wide network security.

              The  Company offers  a  suite  of products  that are  designed  to
     address the  elements of a  comprehensive enterprise-wide network  security
     solution.    The  Company's three  major  network  security  products  are:
     SmartGATE(TRADEMARK), a client/server product  that  offers identification 
     and   authentication,   integrity,   non-repudiation,   authorization,  and
     encryption;  SmartWall(REGISTERED TRADEMARK), an application level firewall
     that  incorporates  SmartGATE's  functionality; and  SmartCAT(TRADEMARK), a
     smart  card-based product  that offers  authentication and  encryption.  In
     addition, the Company provides  integrated security applications  software,
     including SmartREM(TRADEMARK), which will provide a  secure environment for
     sending and  receiving e-mail over  the Internet and  intranets, and Wallet
     Technology,  a secure  electronic payment  system.   The Company's  modular
     suite  of products  can  be combined  and  configured to  provide perimeter
     defense,  secure   remote  access,  and  intra/inter-enterprise   security,
     allowing the  Company's customers  to securely  and easily  deploy a  broad
     range of applications and services on the Internet and intranets.  

              The  Company's  marketing  strategy  is  to achieve  broad  market
     penetration   through   multiple  distribution   channels,   including  the
     Company's   direct  sales   force,  Internet   service  providers,  systems
     integrators,  value-added  network  service  providers,  and  international
     distributors.   In particular,  the Company  has focused  its direct  sales
     efforts  on certain  vertical markets  that  require sophisticated  network
     security  solutions, including financial institutions, information services
     companies,  and  government agencies.    The Company  has  also established
     strategic relationships  with marketing  and licensing  partners to  expand
     the reach  of  its marketing  efforts.   The  Company believes  that  these
     alliances  provide  a  cost  effective  means  by  which  the  Company  can
     efficiently penetrate new markets.  For example, a major telecommunications
     company is currently deploying a  multi-purpose  secure campus card program
     that utilizes the Company's technology  at  a large university.  This smart
     card-based solution  uses the Company's  SmartGATE, SmartWall, and SmartCAT
     products,  and  when fully  deployed, will  permit the  university's 30,000
     students  to  obtain secure access  to  their  university  records, student

                                        3

     information,  and  campus services via  the Internet.  The smart cards also
     include stored value, which may be transferred directly from  the student's
     bank account, for use at on- and  off-campus vendors. The Company  believes
     that  the major telecommunications  company intends  to promote  this smart
     card-based solution at other colleges and universities.

              The  Company  was incorporated  in Maryland  in February  1993 and
     reincorporated  in  Delaware in  February  1996.   The  Company's principal
     executive  offices  are located  at  1803  Research Boulevard,  Suite  305,
     Rockville, Maryland  20850.  The  Company's telephone number  is (301) 838-
     8900,  and  its World  Wide  Web ("Web")  address  is http://www.v-one.com.

                                     RISK FACTORS


              In addition to the other  information included in this Prospectus,
     the following risk  factors should be carefully considered in evaluating an
     investment in the Common Stock offered by this Prospectus.  

     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 revenue until  1995 when it  commenced sales  of its  SmartWall
     firewall  product  and   introduced  its  SmartGATE  client/server  system.
     Revenues  for 1995  and  for the  three  months ended  March 31,  1996 were
     approximately  $1,104,000   and  $1,022,000,  respectively.  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 March  31, 1996,  the  Company
     had accumulated  a  deficit of  approximately  $2.5 million.   The  Company
     currently  expects to  incur  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.

     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 revenue.    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  marketing  operations,  distribution  channels,

                                          7
<PAGE>






     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 sold  by the Company, 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  the Company's  products  successfully,  the  mix  of
     products and services sold,  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

     Condition and Results of Operations."


     Conversion of Series A Stock

              In the event that the  initial offering price per share  of Common
     Stock  offered hereby is not  at least $5.25 per  share, the Series A Stock
     does not  automatically  convert on  a  one-for-one  basis into  shares  of
     Common Stock.   In such  event, the conversion  ratio will  be adjusted  so
     that shares  of Series  A  Stock are  convertible, at  the option  of  each
     holder of  Series A Stock,  into shares of  Common Stock on  a greater than
     one-for-one basis,  which will increase the dilution suffered by purchasers
     of the Common Stock offered  hereby.  Further, if  the holders of Series  A
     Stock do not convert  their shares into shares of Common Stock,  the Series
     A  Stock  will  remain  outstanding  following  the  consummation   of  the
     Offering.  This will limit the  ability of the Company to pay  dividends on
     the  Common Stock  and will  further limit  the  rights of  the holders  of
     Common  Stock.   See  "Dividend Policy,"  "Dilution,"  and "Description  of
     Capital Stock - Series A Convertible Preferred Stock."

     Competition

              The  Company  competes  in  several  different   network  security
     markets:  Internet  and  intranet  perimeter  defense  and  access  control
     (firewalls), token authentication, smart  card-based security applications,
     and electronic commerce applications.  The  Company's principal competitors
     for Internet  and intranet perimeter  defense include Advanced Network  and
     Services  (a  subsidiary  of America  Online,  Inc.),  Bay Networks,  Inc.,
     Border  Network Technologies, Inc., Check Point  Software Technology  Ltd.,
     Cisco   Systems,  Inc.,  Digital  Equipment  Corporation,  Harris  Computer
     Systems Corporation,  International Business Machines Corporation, Milkyway

                                          8

     Networks  Corporation,  Morningstar  Technologies,  Inc.,  Network  Systems
     Corporation,  Raptor  Systems,  Inc.,  Secure  Computing  Corporation,  Sun
     Microsystems,  Inc.,  and  Trusted Information System Inc.'s ("TIS"), which
     owns the Gauntlet(TRADEMARK) kernel and licenses it to the Company.  

              The  Company  competes to  a  lesser  degree  with  token  vendors
     because  the  Company's  SmartGATE product  supports  many  vendor  tokens.
     Token   vendors  include   Security  Dynamics,   Digital  Pathways,   Inc.,
     CRYPTOCard  Inc.,  Leemah  DataCom  Security  Corporation,  Racal-Guardata,
     Inc.,  and  National Semiconductor  Inc.   Security  Dynamics  has recently
     agreed  to  acquire RSA  Data Security, Inc. ("RSA").   RSA's technology is
     licensed  to and incorporated within certain  products of the  Company.  As
     a result, Security Dynamics may become a more substantial competitor of the
     Company.
              For  smart   card-based   security   applications,   the   Company
     principally competes with  those token vendors listed above who offer smart
     card technology.

              The  Company's   principal  competitors  in  electronic   commerce
     applications are Netscape  Communication's Secure Socket Layer  (SSL), Open
     Market Inc.'s  Secure HTTP (S-HTTP),  and Cylink Corporation's  transaction
     software.  See "Business - Competition."

              Because of  the rapid  expansion of the  network security  market,
     the Company will  face competition from existing and new entrants, possibly
     including the Company's customers, suppliers,  or resellers.  There  can be
     no  assurance  that  the  Company's competitors  will  not  develop network
     security products that may be more effective than the Company's current  or
     future products or that the  Company's technologies and products  would not
     be rendered obsolete by such developments.

              Many  of  the Company's  current  and  potential  competitors have
     longer  operating  histories, greater  name  recognition, larger  installed
     customer  bases,  and   significantly  greater  financial,  technical,  and
     marketing resources than the  Company.  As  a result, they  may be able  to
     adapt more quickly to new  or emerging technologies and changes in customer
     requirements, or to devote  greater resources to the promotion and  sale of
     their  products than  the Company.   There  can  be no  assurance that  the
     Company's customers will  not perceive the products of such other companies
     as substitutes for the Company's products.

              The  Company  believes  that  the  principal  competitive  factors
     affecting the market  for network security products  include effectiveness,
     scope of product  offerings, technical features, ease of  use, reliability,
     customer  service and  support, name  recognition, distribution  resources,
     and  cost.   Current  and potential  competitors  have established,  or may
     establish in the future, strategic  alliances to increase their  ability to
     compete  for  the Company's  prospective  customers.   Accordingly,  it  is
     possible that new competitors or  alliances may emerge and  rapidly acquire
     significant  market share.   Such  competition  could materially  adversely
     affect  the  Company's  business,  financial  condition,   and  results  of
     operations.

     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 May 31, 1996,  the Company had grown to 52  employees, from 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 transactions would place additional  strains upon
     the  Company's management  resources.   See  "Management"  and "Business  -
     Employees."

     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.  See "Business
     - Industry Background."

     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

                                          10
<PAGE>






     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 beyond the
     Company's control,  could have a  material adverse effect  on the Company's
     business, financial condition, or results  of operations.  See  "Business -
     Industry Background."

     Dependence on Principal Products; Uncertainty of Product Acceptance

              The Company  currently generates  most of  its  revenues from  its
     SmartWall firewall and  SmartGATE products.   Accordingly, any  factor that
     adversely affects sales  of these products  could have  a material  adverse
     effect  on  the Company.    While the  SmartWall  firewall has  met  with a
     favorable degree  of market acceptance  since sales commenced  in the first
     quarter of 1995, there  can be no assurance that SmartWall will continue to
     be accepted  in the future.   In addition,  there can be  no assurance that
     there will be market acceptance  of the Company's SmartGATE  product, which
     was introduced  in the  fourth quarter  of 1995,  or 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.   See  "Business  -  Products  and  Services," and  "-
     Product Development."


     Dependence on Key Licensing Agreements, External Resources and Suppliers

              The Company  relies and intends  to continue to  rely on  external
     resources  for  the   development  of  certain  of  its  products  and  the
     components  thereof.   The Company's  SmartWall  product  incorporates  the
     TIS   Gauntlet(TRADEMARK)   kernel.    The   Company   licenses   the   TIS
     Gauntlet(TRADEMARK) kernel under a license agreement with TIS that requires
     the Company to pay a fee, which  varies based  on   the  number   of  units
     licensed,  for  each  unit  of   the   Gauntlet(TRADEMARK) kernel  licensed
     for  use  in  SmartWall.   The  license  expires   on  December  31,  1996;
     however,   the  agreement  provides  for  the  automatic   renewal  of  the
     Company's  license  rights  for  successive three year terms.  Either party
     may  terminate  the agreement upon the default  of the  other party if  the
     defaulting  party  has  failed  to cure  the default within 30  days of the
     receipt of written  notice of default.  In addition, TIS may  terminate the
     agreement upon any  second or subsequent  breach of the  agreement  by  the
     Company or  upon  the  Company's  insolvency  or bankruptcy.  See "Business
     - License Agreements."

              The Company's SmartCAT and Wallet  Technology software incorporate
     data encryption  and authentication technology owned  by RSA.  The  Company
     has  a perpetual  license agreement  with RSA, which became effective as of
     December 30,  1994.    Either  party  may

                                          11
<PAGE>






     December  30,  1994.   Either party may terminate  the agreement  upon  the
     default  of  the other  party  if  the defaulting party has  failed to cure
     the default  within 30  days of  the receipt of written  notice of default.
     The  agreement  also may  be terminated by either party upon the insolvency
     or  bankruptcy  of  the other party.  RSA  has announced that  RSA  will be
     acquired  by  Security  Dynamics Technologies, Inc. ("Security  Dynamics"),
     whose   products   compete   with  the  Company's  products  in  the  token
     authentication   market.   There  can be no  assurance  that the change  in
     control of RSA will not adversely  affect the  Company's business relation-
     ship  with  RSA,  which  could  have  a  material  adverse  effect  on  the
     Company's  business,  financial  condition, and  results of operations. See
     "Business - License Agreements."  

              There  can  be no  assurance  that  the Company  will  be able  to
     maintain its license rights for  the TIS Gauntlet(TRADEMARK) kernel  or the
     RSA data  encryption and  authentication technology  and the  loss of  such
     rights could  have a  material adverse  effect on  the Company's  business,
     financial condition,  and results  of operations.   The  Company is  in the
     process of developing its own  technology to replace the  licensed firewall
     technology.     However,   the   Company's   firewall  technology   is   in
     developmental stages  and, until it  is tested and  integrated, the Company
     intends  to rely on  the technology  licensed from  TIS.   The loss  of, or
     inability  to  maintain,  such technology  licenses  could  result in  lost
     sales, delays in delivery of  the Company's current products  and services,
     or  delays  in the  introduction  of new  products  and services  until the
     Company's  technology  is  finally  developed  and   tested  or  equivalent
     technology, if  available, is identified,  licensed, and integrated,  which
     could have a material adverse  effect on the Company's  business, financial
     condition, or results of operations.  See "Business - License Agreements."

     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 its  proprietary rights.  The Company  has pending three
     patent  applications with  the United  States Patent  and Trademark  Office
     that cover certain aspects of  its technology.  Prosecution of these 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 or that any future patents  will
     not be challenged,  invalidated or circumvented, or that the rights granted
     thereunder will  provide competitive  advantages to the  Company.  Further,
     the Company has  not pursued patent protection outside of the United States
     for the technology covered by two of the  pending patent applications.  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.  

                                          12
<PAGE>






              The  Company's  success  is  also  dependent  in  part   upon  its
     proprietary software  technology.   There  can  be  no assurance  that  the
     Company's  trade   secrets  or   non-disclosure  agreements  will   provide
     meaningful protection  for the Company's  proprietary technology and  other
     proprietary information.   In addition, 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.   Further,  there can  be no  assurance that  others
     will  not  independently  develop similar  technologies  or  duplicate  any
     technology developed by the Company  or that the Company's  technology will
     not  infringe upon  patents,  copyrights,  or other  intellectual  property
     rights owned by others.  

              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  abroad may not be  protectable in 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  significant 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.

              The Company  is aware of  two pending law suits  involving RSA and
     Cylink Corporation ("Cylink")  and Cylink's wholly owned  subsidiary, Caro-
     Kann Corporation ("Caro-Kann").   In the first law suit (N.D. Cal.  No. C94
     02332 CW) filed in 1994, Cylink sued  RSA in a declaratory judgment  action
     seeking a declaration from the court  that U.S. Patent No. 4,405,829  ("MIT
     Patent"), under  which RSA is licensed, is invalid  and unenforceable.  RSA
     counterclaimed that  Cylink and Caro-Kann  were infringing the MIT  Patent.
     In  a  related  proceeding,  Cylink  and  Caro-Kann  initiated  arbitration
     against RSA pursuant  to the terms  of a partnership agreement  among those
     parties.   In  the  arbitrator's decision,  issued  in September  1995, the
     partnership was  dissolved.  The  arbitrators determined that  RSA does not

                                          13
<PAGE>






     have the  right  to  sublicense  third  parties  under  U.S.  Patents  Nos.
     4,200,790,  4,218,582,  and  4,424,414  ("Stanford  Patents"), under  which
     Caro-Kann was  licensed.   The  arbitrators  stated  further that,  if  RSA
     provides code to third parties that causes  an infringement of the Stanford
     Patents,  nothing in  the  arbitrator's decision  would prevent  Cylink and
     Caro-Kann from  pursuing their rights  under the  Stanford Patents  against
     such third parties.   According to documents filed  in the second law suit,
     discussed  below, Cylink  sent letters  to certain  RSA licensees  advising
     them  that they need  a license from Cylink  under the  Stanford Patents to
     use the RSA software.  RSA has informed its customers that a  sublicense to
     the Stanford  Patents is  not necessary  to practice  the RSA  cryptography
     method.  In the second law suit  (N.D. Cal. C95-03256 WHO) filed  September
     15, 1995,  RSA sued Cylink and  Caro-Kann in a  declaratory judgment action
     seeking  a  declaration   that  the   Stanford  Patents  are   invalid  and
     unenforceable.    Cylink and  Caro-Kann  have  counterclaimed  that RSA  is
     liable  for direct infringement of the  Stanford Patents and also is liable
     for contributory  infringement and  inducing infringement  of the  Stanford
     Patents by  virtue  of RSA's  license  of  certain RSA  software  to  third
     parties.  To the best  of the Company's knowledge, both law suits are still
     pending.   There can  be no assurances  that Cylink  will not initiate  law
     suits  against RSA  licensees,  including the  Company.   In  the Company's
     license agreement with RSA, RSA agreed that RSA would, at its own  expense:
     (i)  defend,  or at  its  option  settle, any  claim,  suit,  or proceeding
     against  the Company, including any  claim, suit,  or proceeding instituted
     by Cylink, Caro-Kann, or an entity related to either  of them, on the basis
     of infringement of any United States patent,  copyright, or trade secret in
     the field  of cryptography  regarding the  unmodified software  licensed by
     RSA  or any claim that  RSA has no right to  license the software; and (ii)
     pay  any final judgment or  settlement entered against  the Company on such
     issue in  any suit  or proceeding  defended by  RSA.   RSA's obligation  to
     indemnify  the Company  survives the termination  of the license agreement.
     There can  be no assurance  that the outcome  of the law  suits between RSA
     and Cylink will support RSA's  position.  If the outcome of the  lawsuit is
     adverse  to RSA, there  can be  no assurance  that Cylink will  license its
     technology to  the Company  on commercially  reasonable terms,  or at  all.
     Any royalty obligations  to Cylink by the  Company would not be  covered by
     RSA's indemnification  obligation to  the Company.   There also  can be  no
     assurance  that the Company  will be able to  obtain or develop alternative
     technology on commercially  reasonable terms, if  at all.  See  "Business -
     License  Agreements"  and  "Business  -  Patents,  Proprietary  Technology,
     Trademarks, and Licenses."

              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.   See
     "Business - Patents, Proprietary Technology, Trademarks, and Licenses."

     Changes  in   Technology  and  Industry  Standards;  Risk  of  New  Product
     Introduction

                                          14
<PAGE>






              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.   The
     Company believes that customer  support will remain a critical piece of its
     services offering.   The Company  intends to enhance  its existing customer
     service system by adding toll-free line support and  moving to a three-tier
     support system.   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  and expanded  customer  support  services 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.     See  "Business   -  Product
     Development."

     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.

     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 the
     Company's  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

                                          15
<PAGE>






     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.   While the  Company attempts to
     reduce the risk of such  losses through warranty disclaimers  and liability
     limitation clauses  in its license  agreements, and by maintaining  product
     liability insurance, there can  be no assurance that such measures  will be
     effective in limiting  the Company's liability for  any such damages.   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  intends to  purchase
     product liability  insurance and it may  seek additional insurance coverage
     as  it commences  commercialization  of  its products.    There can  be  no
     assurance that adequate additional  insurance coverage will be available at
     an acceptable  cost, if at  all.  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.

     Evolving Distribution Channels

              Currently, the Company relies  primarily on its direct sales force
     for the sale  and marketing of its products.   The Company plans to  add to
     its  internal sales  and marketing  staff in  order to increase  its direct
     sales effort.  There  can be no assurance that such internal expansion will
     be  successfully completed, that 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 the  Company's
     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.
     The Company is  beginning to establish its  reseller distribution  channel.
     There  can be  no  assurance  that the  Company  will  be able  to  attract
     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 anticipates that  it will ship  products
     to distributors and  resellers on a purchase-order basis, and the Company's
     distributors  and resellers  will  likely  carry competing  product  lines.
     Therefore, there can be no assurance that any distributor or reseller  will
     continue to  represent the Company's  products.  The  inability to recruit,
     or  the  loss of,  important  sales personnel,  distributors,  or resellers

                                          16
<PAGE>






     could  materially  adversely  affect  the   Company's  business,  financial
     condition, and results of operations in the future.   See "Business - Sales
     and Marketing."

     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
     revenue.  As a result, product revenue 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 revenue falls  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 revenue  in the third
     and fourth quarters of the  year and lower revenue in the  first and second
     quarters.  The Company  believes that revenue 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 the Company's 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,
     including the  net proceeds  of  the sale  of the  shares of  Common  Stock
     offered hereby, will  be adequate to  satisfy its  capital requirements  at
     least  through 1997.  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 this
     Offering 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


                                          17

     significantly.   See  "Management's Discussion  and  Analysis of  Financial
     Condition and Results of Operations - Liquidity and Capital Resources."

     Risk of Sales to U.S. Government

              In 1995, the Company derived a substantial portion of its  revenue
     from the sale of the SmartWall firewall to departments and agencies of  the
     U.S.  government  and  government contractors.    In  1996,  the  Company's
     revenues will be  attributable, in part, to  a contract with NSA.   Because
     no  government  agency 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 to the  development capabilities of the  Company and
     the reliability and perception  of the Company's products.  There can be no
     assurance  that  the  Company  will  be  able  to  sell   its  products  to
     departments and agencies of the U.S.  government and government contractors
     or  that such sales,  if any, will result  in commercial  acceptance of the
     Company's products.   There also is no  assurance that the Company  will be
     able to procure  an extension of its  current NSA contract when  it expires
     in  September 1996  or  additional contracts  of  similar magnitude  in the
     future.   In addition, reductions or delays  in federal funds available for
     projects the  Company is performing  or to purchase  the Company's 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 an
     adverse impact on the Company's business,  financial condition, and results
     of operations.  See "Business - Regulation and Government Contracts."

     International Sales 

              The Company plans to increase 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 the  Company expands
     international  sales,   currency  fluctuations  could  make  the  Company's
     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

                                          18
<PAGE>






     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. See " Business  - Sales and
     Marketing."

     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 will be subject
     to the  export restrictions administered  by the U.S.  Department of State,
     which  permit the  export  of encryption  products  only with  the required
     level of export license.   These  export laws also  prohibit the export  of
     encryption products to a  number of hostile countries.  In  certain foreign
     countries, the Company's  distributors will be required to  secure licenses
     or formal permission before encryption products can be imported.   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. See " Business - Technology," and "-
     Products."

     Dependence on Key Personnel

              The Company's  success will depend,  to a large  extent, upon  the
     performance  of its  senior management  team and  technical, marketing  and
     sales 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 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
     million "key man" life insurance policies on the lives of each of James  F.
     Chen, its  founder and  Chief Executive  Officer, and  Jieh-Shan Wang,  its
     Senior Vice President of Engineering.   This coverage, however, may not  be
     sufficient to  mitigate the  impact that the  loss of  the services of  Mr.
     Chen or Mr. Wang would have on the Company.  See "Management."

     Certain Anti-takeover  Provisions of Certificate of  Incorporation, Bylaws,
     and Delaware Law

              The  Company's Amended  and Restated Certificate  of Incorporation
     ("Restated Certificate of  Incorporation") and Amended and  Restated Bylaws
     ("Restated Bylaws") provide  that any action  required or  permitted to  be
     taken by  shareholders of  the Company  may be  effected at  a duly  called
     annual  or special  meeting.   If a  shareholder  wishes a  proposal to  be
     considered at  an annual or special  meeting under the Restated  Bylaws, he
     or she must  give reasonable advance notice to  the Company.  The Company's
     Restated Bylaws  permit only  the Company's  Chief Executive  Officer or  a
     majority of  the members  of the  Company's Board  of Directors  to call  a
     special  meeting  of shareholders.    In addition,  the  Company's Restated
     Certificate of Incorporation  provides that,  at the  1996 annual  meeting,
     the Company's Board of  Directors will be classified into three  classes of
     directors.  Under  the Restated Certificate of  Incorporation and  Restated
     Bylaws, a  Director may be  removed only for  cause and by the  affirmative
     vote of  67% of  the outstanding  shares entitled  to vote  an election  of
     directors at a special meeting called for that purpose.

              In addition, the Board of Directors  has the authority to issue up
     to  20,000,000  shares of  Preferred  Stock  and  to  determine the  price,
     rights, preferences,  privileges and restrictions,  including voting rights
     of  those  shares, without  any  further vote  or  action by  the Company's
     shareholders.  The  rights of the holders  of Common Stock will  be subject
     to, and  may be adversely  affected by,  the rights of  the holders  of any
     Preferred  Stock that  may  be  issued in  the  future.   The  issuance  of
     Preferred Stock, while  providing desirable flexibility in  connection with
     possible acquisitions and other corporate  purposes, could have the  effect
     of making it more difficult  for a third party to acquire a majority of the
     voting stock of  the Company.  The  Company has issued 1,186,518  shares of
     Series A Stock, which, assuming  the initial offering price  exceeds $5.25,
     will convert into  1,186,518 shares of  Common Stock  upon consummation  of
     the Offering.  The  Company has  no present plans  to issue any  additional
     series of Preferred  Stock upon the consummation of the Offering.  Further,
     certain provisions of the Company's Restated  Certificate of Incorporation,
     Restated Bylaws, and Delaware  law could delay or make difficult  a merger,
     tender offer  or proxy  contest involving  the Company.   In addition,  the
     Company is subject  to Section 203 of the  Delaware General Corporation Law
     ("Section  203"),  which  places certain  restrictions  on  the ability  of
     Delaware corporations  to engage in  business combinations with  interested
     shareholders.  See  "Description of Capital  Stock -  Preferred Stock"  and
     "   -  Anti-takeover   Effects  of   Provisions  of   the   Certificate  of
     Incorporation, Bylaws, and Delaware Law."

     No Prior Public Market; Market Volatility

              Prior to  this Offering, there  has been no public  market for the
     Company's Common  Stock,  and there  can be  no  assurance that  an  active
     public market for  the Company's Common Stock will  develop or be sustained
     following  the Offering.  The  initial public offering  price of the Common
     Stock will  be  determined  in  negotiations  among  the  Company  and  the

                                          20
<PAGE>






     Underwriters  based upon several factors and may be greater than the market
     price for the  Common Stock following  the Offering.   See  "Underwriting."
     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  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.  There can be no assurance
     that the market price  of the Common Stock offered hereby will  not decline
     below the initial public offering price.  

     Concentration of Share Ownership

              Upon  completion  of   this  Offering,   the  current   directors,
     executive officers  and their respective  affiliates will beneficially  own
     approximately  59.5%  of the  Company's  outstanding  Common Stock  in  the
     aggregate on a  fully-diluted basis (57.4%  in the  event the  Underwriters
     exercise the over-allotment option in full).  This  does not give effect to
     the exercise of options to purchase  1,304,708 shares of Common Stock  held
     by  these  individuals,  which, if  exercised  in whole  or  in  part, will
     further concentrate ownership of the Company's Common  Stock.  As a result,
     these  shareholders will  retain  the voting  power  required to  elect all
     directors and  to  approve  all  other  matters  requiring  approval  by  a
     majority  of  the shareholders  of  the  Company.    Such concentration  of
     ownership may also  have the effect of  delaying or preventing a  change in
     control of  the  Company.    See  "Management  -  Directors  and  Executive
     Officers" and "Principal Shareholders."

     Potential Effect of Shares for Future Sale

              Sales of substantial amounts of Common Stock in the public  market
     following  the Offering  could  adversely affect  the  market price  of the
     Common Stock.    Upon completion  of the  Offering, the  Company will  have
     outstanding an aggregate of 14,040,638 shares  that are "restricted" shares
     under the Securities Act of 1933, as amended (the "Securities Act").   Only
     the 3,400,000 shares  of Common Stock offered  hereby will be  eligible for
     sale in the public  market immediately following the effective date  of the
     registration statement on  Form S-1 relating  to the  Common Stock  offered
     hereby ("Registration  Statement") filed with  the Securities and  Exchange
     Commission ("SEC"), excluding the  Common Stock to be offered  in the over-
     allotment  option.     Certain  of  the  Company's   current  shareholders,
     employees, directors,  officers, and  holders of  options  and warrants  to
     purchase Common Stock have agreed with  Representatives of the Underwriters
     not  to sell  or  otherwise  dispose of  any  shares  of Common  Stock  not
     included in the  over-allotment option for a  period of 180 days  after the
     date of this  Prospectus without the  consent of  the Underwriters.   After
     the expiration of the  180-day period, 1,698,983 shares of Common Stock may

                                          21
<PAGE>






     be  sold in compliance with Rule 144 or  Rule 701 under the Securities Act.
     The number  of  shares  eligible  for  resale  assumes  the  conversion  of
     1,186,518 shares of Series  A Stock on a one-for-one basis, the issuance of
     280,812  shares to  RSA and Massachusetts  Institute of Technology ("MIT"),
     and the exercise, by June 30, 1996, of  warrants to purchase 100,000 shares
     of Common Stock  at $0.01.  The holders  of Common Stock issuable  upon the
     conversion of Series  A Stock and  the holders  of warrants exercisable  at
     $0.01 and  $3.00  per share  will  have contractual  rights  to have  those
     shares registered under the Securities Act for  resale to the public.   See
     "Shares Eligible for Future Sale."

     Absence of Dividends

              No dividends  have been paid on  the Common Stock to  date and the
     Company does  not anticipate paying  dividends in  the foreseeable  future.
     See "Dividend Policy."

     Dilution

              Purchasers  of the  Common  Stock offered  hereby  will experience
     immediate and substantial dilution in net tangible book  value per share of
     the  Common Stock.    To the  extent outstanding  options  and warrants  to
     purchase the  Company's Common Stock  are exercised, there  will be further
     dilution.  See "Dilution."

                                   USE OF PROCEEDS


              The net  proceeds to be received  by the Company from  the sale of
     the  Common Stock  offered  hereby are  estimated  at $18.3  million ($20.0
     million  if the Underwriters' over-allotment  option is  exercised in full)
     assuming  an  initial public  offering  price  of  $6.00  per share,  after
     deducting  the  underwriting  discount  and   estimated  Offering  expenses
     payable  by the Company.   The Company will  not receive  any proceeds from
     the  sale  of shares  of  Common  Stock by  the  Selling Shareholders  upon
     exercise of the  Underwriters' over-allotment option  in full  or in  part.
     The principal purposes of this  Offering are to obtain  additional capital,
     create a  public  market for  the  Company's  Common Stock  and  facilitate
     future access by the Company to public equity markets.  

              The Company  expects to use  the net proceeds  from this  Offering
     for working  capital and  for other  general corporate purposes,  including
     the  expansion  of  marketing,  sales,  and  customer  support  activities,
     research  and development,  and  capital expenditures.    A portion  of the
     proceeds of this Offering  will be used to  repay a $1.5 million loan  from
     JMI and loans in an  aggregate amount of approximately $143,000 from  James
     F. Chen,  the  Company's  President  and  Chief  Executive  Officer.    See
     "Certain Transactions."  In addition, a portion of  the net proceeds may be
     used to acquire  or invest in related  businesses or products or  to obtain
     the right  to use technologies that would broaden  or enhance the Company's
     products.  The Company has no present  plans, agreements or commitments and
     is not  currently  engaged in  any negotiations  with respect  to any  such
     transactions.   Pending such  use of  the proceeds, the  Company intends to
     invest  the   funds  in  short-term,  interest-bearing,   investment  grade
     securities.

                                   DIVIDEND POLICY

              The Company  has never  declared  or paid  cash dividends  on  its
     Common Stock or other securities.  The Company  anticipates that all of its
     net  earnings, if any, will be retained  for use in its operations and does
     not  anticipate  paying  cash  dividends   on  its  Common  Stock   in  the
     foreseeable future.  Payments of future cash dividends,  if any, will be at
     the discretion  of  the Company's  Board  of  Directors after  taking  into
     account  various  factors,  including the  Company's  financial  condition,
     operating results, and current  and anticipated cash needs.  The holders of
     Common Stock are  not entitled to receive  dividends as long as  any shares
     of  the Company's Series  A Stock  are issued  and outstanding.   See "Risk
     Factors -  Conversion of Series  A Stock," "Description of  Capital Stock -
     Common  Stock," and  "Description of  Capital  Stock -Series A  Convertible
     Preferred Stock."

     offering  price  of $6.00  per  share  and  after  deducting the  estimated
     underwriting discount  and offering expenses),  assuming the conversion  of
     all  Series  A Stock  on  a one-for-one  basis  into Common  Stock  and the
     application of the net proceeds from this Offering as  described under "Use
     of  Proceeds."   See  "Risk Factors  - Conversion  of  Series A  Stock" and
     "Description of Capital Stock -  Series A Convertible Preferred  Stock" for
     a description  of the  conversion of the  Series A  Stock on a  one-for-one
     basis,  which  will  occur  automatically  if the  initial  offering  price
     exceeds $5.25 per share of Common Stock.

     (1)  The Company's  Restated  Certificate of  Incorporation authorizes  the
          Company  to issue  up to  20,000,000 shares  of  Preferred Stock.   On
          April  4,  1996, the  Board of  Directors  authorized the  issuance of
          1,183,402 shares of Series A Stock and  on May 12, 1996, the Board  of
          Directors authorized  the issuance of  an additional  6,071 shares  of
          Series  A Stock.   As of June 12,  1996, 1,186,518 shares  of Series A


                                          24

          Stock have been issued.  See "Description of Capital Stock  - Series A
          Convertible Preferred Stock." 

     (2)  In December 1995 and  January 1996, the Company borrowed  $2.5 million
          through the  sale of 7%  interest bearing, unsecured  Promissory Notes
          ("Notes")  ("Note Offering").   In  April and  May  1996,  the Company
          exchanged all  of  the  Notes  (principal and  accrued  interest)  for
          shares  of the  Company's Series  A  Stock, at  a price  of  $3.00 per
          share.   In addition, the  Company permitted the  certain investors to
          purchase an additional 333,333 shares of Series A Stock at  a price of
          $3.00 per share.   Assuming the initial offering price  exceeds $5.25,
          shares of Series A  Stock will convert to  Common Stock on a  one-for-
          one basis  on  consummation of  the Offering.    See "Risk  Factors  -
          Conversion of Series  A Stock,"  and "Description of  Capital Stock  -
          Series A Convertible Preferred Stock." 

     (3)  Excludes 280,812 shares  of Common  Stock reserved  for issuance  (see
          "Business  -  Licensing  Agreements")  and warrants issued  to JMI  to
          purchase 100,000 shares of Common Stock  at an exercise price of $0.01
          per  share, which must  be exercised by  June 30, 1996.   See "Certain
          Transactions."


                                       DILUTION

          The net tangible book  value of the Company  as of March 31,  1996 was
     $(1,135,000)  or $(0.09)  per share  of  Common Stock.   Net  tangible book
     value  per share  represents  the amount  of  the Company's  total tangible
     assets less total  liabilities divided by  the number of  shares of  Common
     Stock outstanding.   Without taking into  account any other changes  in the
     net tangible book value after March 31, 1996, other  than to give effect to
     the receipt  by  the Company  of  the net  proceeds from  the  sale of  the
     3,400,000 shares  of Common  Stock offered  by  the Company  at an  assumed
     offering  price  of $6.00  per  share  and  after  deducting the  estimated
     underwriting  discount and  offering expenses,  the  adjusted net  tangible
     book  value  of  the  Company  as  of  March  31,  1996  would  have   been
     approximately  $17.2  million or  $1.08  per  share.    This represents  an
     immediate  increase  in net  tangible  book  value of  $1.17  per  share to
     existing shareholders and an immediate dilution  of $4.92 per share to  new
     investors.  The following table illustrates this per share dilution:

     (1)  In  the  event the  Underwriters  exercise  the over-allotment  option
          granted by the  Company and  the Selling Shareholders,  the number  of
          shares  held by existing shareholders will be reduced to 12,240,173 or
          approximately  77.2% of the outstanding shares of the Common Stock and
          will increase the number of shares held by new  investors to 3,616,468

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

              This Prospectus contains,  in addition to  historical information,
     forward-looking  statements  that  involve  risks  and  uncertainty.    The
     Company's  actual  results  could differ  significantly  from  the  results
     discussed in the forward-looking statements.   Factors that could  cause or
     contribute to  such differences  include those discussed  in "Risk Factors"
     as well as those discussed elsewhere in this Prospectus.

     Overview

              The Company develops, markets,  and licenses a comprehensive suite
     of  network  security  products that enable  businesses to  conduct secured
     electronic transactions  and information exchange  using private enterprise
     networks and  public networks  such  as the  Internet.   From inception  in
     February  1993 until  December  1994,  the Company's  operating  activities
     related  primarily to  recruiting personnel,  and  conducting research  and
     development.   Revenues were  minimal during  1993 and 1994.   The  Company
     introduced  its  first   product,  the  SmartCAT  smart  card   reader  and
     application  software,  in  October  1994  and  its   second  product,  the
     SmartWall application-level firewall, in December 1994.  In December  1995,
     the  Company  introduced  SmartGATE,  a   client/server  security  enabling
     product.

              From inception  until December  1994, the Company's  revenues were
     generated primarily from  consulting and services.   Currently, the Company
     generates revenues primarily from software  licenses and sale of  hardware,
     and to  a lesser  extent, consulting  and related  services.   The  Company
     anticipates that  revenue from products  will continue to  be the principal
     source of the Company's revenues.  

              Under   the  Company's  revenue  recognition  policy,  revenue  is
     generally recognized from  the license of  software upon  shipment, net  of
     allowances, provided  that no  significant vendor  obligations remain.   In
     addition, the Company often  permits customers  to evaluate products  being
     considered for purchase, generally for a period of up  to 30 days, in which
     event  the  Company does  not  recognize  revenue  until  the customer  has
     accepted  the  product.  Accordingly,  the  Company's  revenue  recognition
     policy  does  not necessarily  correlate  with  signing  of  a contract  or
     shipment of a product.  See "Risk Factors - Long Sales Cycle."

              As  of March 31, 1996,  the Company had  an accumulated deficit of
     approximately $2,500,000.    The Company  currently  expects to  incur  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.    To date,  the  Company has  expensed  all
     development  costs as  incurred in  compliance with  Statement of Financial
     Accounting  Standards  No.  86,  "Accounting  for  the  Costs  of  Computer
     Software to  Be Sold, Leased, or Otherwise Marketed."  The Company believes


                                          30
<PAGE>






     that it  will be  able  to continue  to expense  all development  costs  as
     incurred.

              The Company's President, Chief  Executive Officer, and founder did
     not receive  salary  in 1993,  1994, or  1995,  which resulted  in  reduced
     general and  administrative costs  for  those years.   Mr.  Chen has  begun
     receiving a salary  in 1996 and the Company  recently has hired and intends
     to  continue to hire additional senior level  personnel.  See "Management -
     Employment Agreement."  In addition, general and administrative  costs have
     increased  significantly  since the  Company's  date of  inception  and the
     Company expects such costs to continue to increase in the future.  

              In   1993,   consulting   and   services   revenue   from   MacTec
     Magazine(TRADEMARK)  ("MacTec")  and  IN-SNEC  Groupe  Technique,  an   air
     traffic control  equipment manufacturer  located in  France, accounted  for
     approximately  56% and  13%,  respectively, of  total  revenues.   In 1994,
     consulting and  services revenue  from the  U.S. Department  of Energy  and
     MacTec accounted  for  approximately 37%  and 29%,  respectively, of  total
     revenues.  In 1995,  product revenue from GEIS, NCTS Washington, a division
     of the  Department of the  Navy, and the  U.S. Defense Information  Systems
     Agency  accounted for  approximately 19%,  10%, and  10%, respectively,  of
     total revenues.    For  the three  months  ended  March 31,  1996,  product
     revenue from  Solomon Technology Corporation,  a Taiwanese manufacturer  of
     smart cards, accounted for approximately 20% of total revenues.

     Three Months  Ended  March  31,  1996  Compared  with  Three  Months  Ended
     March 31, 1995

              Revenues

              Total   revenues   increased   significantly   from  approximately
     $150,000  for  the three  months  ended  March  31,  1995 to  approximately
     $1,022,000 for the  three months ended March 31,  1996.  This  increase was
     principally  attributable  to  increased sales  of  the  Company's  network
     security products.  

              Product  Revenue.   Product  revenue is  derived  principally from
     software licenses  and the  sale of  hardware.   Product revenue  increased
     significantly from approximately $150,000 for the three months ended  March
     31, 1995  to approximately $982,000  for the three  months ended March  31,
     1996.    The  increase  was  due  principally to  increased  sales  of  the
     Company's SmartWall product  and the introduction of its  SmartGATE product
     in December 1995. 

              Consulting and Services Revenue.   Consulting and services revenue
     is  derived  principally  from  fees  for  services  complementary  to  the
     Company's  products,   including  consulting,  maintenance,  and  training.
     Consulting  and services  revenue  was approximately  $40,000,  or 3.9%  of
     total revenue, for  the three  months ended March  31, 1996.   The  Company
     anticipates that  consulting  and  services revenues  will  increase  as  a
     percentage  of  total  revenue  as  compared  to  the  three  months  ended
     March 31, 1996.

              Cost of Revenues

              Cost  of  Product  Revenue.    Cost  of  product revenue  consists
     principally  of  the  costs  of  computer  hardware,  licensed  technology,
     manuals, and  labor associated  with the  distribution and  support of  the
     Company's  products.  Cost of product  revenue increased from approximately
     $53,000  for  the  three  months  ended  March 31,  1995  to  approximately
     $311,000  for the  three  months ended  March 31,  1996.   Cost  of product
     revenue  as a percentage  of product  revenue was  35.0% and 31.7%  for the
     three months ended  March 31, 1995 and  March 31, 1996, respectively.   The
     increase in  absolute dollars was  principally related to  the higher level
     of product sales  compared with the prior  year's period.  The  decrease in
     cost of product  revenue as a percentage  of product revenue  was primarily
     due to  an  increase in  sales  of the  Company's  software products  as  a
     component of product revenue in the later period. 

              Cost of Consulting and  Services Revenue. Cost  of consulting  and
     service  revenue  consists  principally  of  personnel  and  related  costs
     incurred  in  providing  consulting,  support,  and  training  services  to
     customers.  There  was no cost of  consulting and services revenue  for the
     three months ended March 31, 1995 as compared to  approximately $11,000, or
     28.1% of  consulting  and services  revenue,  for  the three  months  ended
     March 31, 1996.

              Operating Expenses

              Sales  and  Marketing.    Sales  and  marketing  expenses  consist
     principally  of the  costs of  sales and  marketing personnel, advertising,
     promotions, and  trade  shows.    Sales and  marketing  expenses  increased
     significantly  from  approximately  $34,000  for  the  three  months  ended
     March 31,  1995 to  approximately  $709,000  for  the  three  months  ended
     March 31,  1996.   Sales and marketing  expenses as  a percentage  of total
     revenue were 22.6% and 69.4% for the  three months ended March 31, 1995 and
     March 31,  1996, respectively.   The  dollar and  percentage increase  were
     principally related to  expenses associated with increases in the number of
     sales and marketing personnel, as  well as expenses related  to advertising
     and promotional efforts.  Sales and  marketing expenses can be expected  to
     increase both  in the aggregate  and as a  percentage of total revenues  in
     the near term  as a result of  the Company's increased sales  and marketing
     efforts.  

              General and  Administrative.  General and  administrative expenses
     consist   principally   of   the  costs   of   finance,   management,   and
     administrative  personnel   and   facilities   expenses.      General   and
     administrative   expenses   increased   substantially  from   approximately
     $154,000  for  the three  months  ended  March  31,  1995 to  approximately
     $593,000  for  the  three  months  ended  March  31,  1996.    General  and
     administrative expenses as a percentage  of total revenues were  102.7% and
     58.0%  for  the three  months  ended March  31,  1995 and  March  31, 1996,
     respectively.  In addition,  during the three months ended March  31, 1996,
     the Company  added approximately  $76,000 to its  allowance for potentially
     uncollectible accounts receivable and nonsalable inventory.   The remainder
     of the  dollar increase was principally  attributable to  additional hiring
     of  management and  administrative  personnel  and professional  and  legal
     fees.   The  percentage decrease  was primarily  due to  allocation over  a
     larger  revenue  base.     The   Company  anticipates   that  general   and
     administrative expenses will increase in future periods.

              Research and  Development.    Research  and  development  expenses
     consist principally of the cost  of research and development  personnel and
     other  expenses  associated  with  the  development  of  new  products  and
     enhancement  of  existing  products.   Research  and  development  expenses
     increased significantly  from approximately  $42,000 for  the three  months
     ended March 31, 1995 to  approximately $311,000 for the three  months ended
     March  31, 1996.   Research and  development expenses  as a  percentages of
     total  revenue were 27.7%  and 30.4% for the  three months  ended March 31,
     1995 and March 31, 1996, respectively.  The  dollar and percentage increase
     were principally attributable  to an increase  in the  number of  personnel
     associated  with the Company's technical  development efforts.  The Company
     believes  that a  continuing  commitment  to  research and  development  is
     required  to  remain  competitive.   Accordingly,  the  Company  intends to
     allocate substantial  resources to research  and development, but  research
     and development expenses may vary as a percentage of revenues.

              Interest Income and Expense.   Interest income represents interest
     earned  on  cash, cash  equivalents  and marketable  securities.   Interest

                                          34
<PAGE>






     income  was approximately  $23,000  for the  three  months ended  March 31,
     1996.  Interest  expense was approximately  $105,000 for  the three  months
     ended March  31, 1996.   Interest  expense represents  interest payable  on
     promissory  notes and  capitalized lease  obligations.   See  "Management's
     Discussion and Analysis  of Financial Condition and Results of Operations -
     Liquidity and Capital Resources."
       
              Income Taxes.   The Company did  not incur income tax  expense for
     the three months ended  March 31, 1995 and the three months ended March 31,
     1996 as a result of the net loss incurred during each  period.  As of March
     31,  1996,   the  Company   had  net   operating   loss  carryforwards   of
     approximately  $1,785,000  as  a  result  of   net  losses  incurred  since
     inception.

     Comparison of Years Ended December 31, 1993, 1994, and 1995

              Revenues

              Total revenues decreased 21.6%  from approximately $76,000 in 1993
     to  approximately   $60,000  in   1994  and   increased  substantially   to
     approximately  $1,104,000  in 1995.    The  Company  had  no revenues  from
     products  in 1993 and 1994.  The decrease in revenues from 1993 to 1994 was
     primarily  due to the Company's focus on product development.  The increase
     from 1994 to  1995 was primarily due  to the introduction of  the Company's
     SmartWall product in December 1994.  

              Cost of Revenues

              Cost  of revenues  decreased  7.8% from  approximately  $38,000 in
     1993  to  approximately $35,000  in  1994  and increased  substantially  to
     approximately $377,000 in 1995.  Cost of revenues as a percentage of  total
     revenues  were  50.0%,   58.8%  and  34.2%   in  1993,   1994,  and   1995,
     respectively.   The dollar  decrease and  percentage increase  in 1994  was
     primarily  due to a  decrease in  revenues and  higher service costs.   The
     dollar increase and  percentage decrease in 1995 is  primarily attributable
     to an increase in revenues from the introduction of SmartWall.

              Operating Expenses

              Sales and Marketing.  Sales  and marketing expenses increased from
     approximately  $4,000  in  1993  to  approximately  $21,000  in  1994   and
     increased to approximately  $104,000 in 1995.  Sales and marketing expenses
     as a  percentage of  total revenues  were 4.8%,  35.5%, and  9.4% in  1993,
     1994, and  1995, respectively.   The dollar increase in  1994 was primarily
     due to  the costs  associated with  expanding operations.   The  percentage
     increase in  1994 was primarily  attributable to allocation  over a smaller
     revenue  base.   The  dollar  increase  in  1995  was  principally  due  to
     increased personnel  and marketing  efforts and  costs associated with  the
     sales  of SmartWall.   The percentage decrease in  1995 was principally due
     to allocation over a larger revenue base.

              General and  Administrative.  General  and administrative expenses
     increased from approximately $68,000 in  1993 to approximately $299,000  in
     1994 and  increased  to approximately  $1,315,000  in  1995.   General  and
     administrative  expenses  as a  percentage  of total  revenues  were 89.5%,
     501.4% and  119.1%  in 1993,  1994, and  1995,  respectively.   The  dollar
     increase in 1994  was primarily as  a result of increased  staffing levels.
     The  dollar  increase in  1995  was  primarily  as  a result  of  increased
     staffing  levels, leasing  of additional  office  space, additional  travel
     expense,  establishing  an  allowance  for  potentially  uncollectible  and
     nonsaleable inventory, and increased professional fees.

              Research   Development.     Research  and   development   expenses
     increased from  $0  to approximately  $108,000  in  1994 and  increased  to
     approximately $278,000 in  1995.  Research  and development  expenses as  a
     percentage of total revenues  were 0%, 180.7%, and 25.2% in 1993, 1994, and
     1995,  respectively.  The dollar increases  in 1994 and 1995 were primarily
     due to increases  in the number of personnel  associated with the Company's
     product development efforts.

              Interest  Income and  Expense.   There was  no interest  income in
     1993  and  1994.   Interest income  in 1995  was approximately  $5,000 from
     interest earned on  the net proceeds from the Company's private financings.
     Interest  expense was approximately $2,000 in both 1993 and 1994.  Interest
     expense was approximately  $67,000 in 1995.  The increase was primarily due
     to the Company's issuance of $1,250,000 in promissory notes in 1995.

              Income Taxes.  The  Company did not  incur income tax expenses  in
     December 31,  1993, 1994,  and 1995 as  a result  of the net  loss incurred
     during  these periods.    As of  December  31, 1995,  the  Company had  net
     operating loss  carryforwards of  approximately $1,172,000  as a result  of
     net losses incurred since inception.

              The  Company's total  revenues and  operating results  have varied
     substantially from quarter to  quarter and should not be relied upon  as an
     indication  of   future  results.    Quarterly  operating  results  can  be
     difficult to forecast because the  Company's sales cycle can  be relatively
     long  and depend  on factors  such as  the  size and  timing of  individual
     transactions;  changes in  customer  budget  authorizations; the  level  of
     sales   and  marketing,   research  and   development,   and  general   and
     administrative expenses; and general economic conditions.

              Operating results  for a given period  could be disproportionately
     affected by any  shortfall in expected revenues.   In addition, fluctuation
     in revenues  from  quarter to  quarter  will  likely have  an  increasingly
     significant impact on the Company's  results of operations.   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.  See  "Risk Factors -  Anticipated Fluctuations in
     Quarterly Results."

              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 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  the Company's existing or prospective customers to implement
     changes in computer  or network security prior  to the end of  the calendar
     year.   Because the Company's  operating expenses are  based on anticipated
     revenue levels,  a small variation  in the time of  recognition of revenues
     can cause  significant  variations in  operating  results from  quarter  to
     quarter.

     Liquidity and Capital Resources

              Since its  organization, the  Company has financed  its operations
     through the private sale of  equity securities, notes to  shareholders, and
     short-term  borrowings.  In 1993, the  Company raised approximately $40,000

                                          38

     from the issuance  of an 8%  note.   In 1994 and  1995, the Company  raised
     approximately  $750,000 and  $400,000, respectively,  through  the sale  of
     Common Stock.  In  addition, in December 1995 and January 1996, the Company
     raised $2,500,000  from  the sale  of  the  7% unsecured  promissory  notes
     scheduled to  mature on  June 30,  1996.   In April  and May  of 1996,  the
     Company  exchanged all of  the 7%  unsecured promissory notes  for Series A
     Stock.   In  June  1996, the  Company  raised an  additional $1,500,000  by
     issuing to JMI  an 8% unsecured  senior subordinated  note with  detachable
     warrants   to   purchase   500,000   shares   of   Common   Stock.      See
     "Capitalization,"  "Description of  Capital Stock  -  Series A  Convertible
     Preferred Stock," and "Certain Transactions."

              In October 1995,  the Company  obtained a  secured equipment  loan
     from a  bank in  the amount  of $50,000 at  the bank's  prime rate  for the
     first year, which  is scheduled to increase  to the bank's prime  rate plus
     1.5% in October 1996.   The Company is required  to repay the loan  over 36
     months commencing in October  1996 and ending in October 1999.   The amount
     outstanding under this loan at March 31,  1996 totalled $50,000.  At  March
     31, 1996, the bank's prime rate was 8.25%.

              The  Company's operating  activities  used cash  of  approximately
     $21,000,  $353,000, and  $1,121,000 in 1993,  1994, and 1995, respectively.
     For the  three  months  ended  March  31,  1996,  the  Company's  operating
     activities used  cash of $967,000.   Cash used in  operating activities was
     principally a result  of net losses  and increases  in accounts  receivable
     and  inventory,  which  were partially  offset  by  increases  in  accounts
     payable   and  the   establishment   of   an  allowance   for   potentially
     uncollectible accounts receivable and nonsaleable inventory.

              Capital   expenditures   for   property    and   equipment    were
     approximately  $20,000,  $13,000,  and $20,000  in  1993,  1994, and  1995,
     respectively.   Capital expenditures for  the three months  ended March 31,
     1996 were  $155,000.  These  expenditures have generally  been for computer
     workstations and  personal computers, office  furniture and equipment,  and
     leasehold  additions and  improvements.   The Company  expects to  purchase
     additional computer  equipment and  office furniture  in 1996.  The Company
     may  use  a  portion  of  the  net  proceeds  of  this  Offering  for  such
     expenditures.

              The Company believes  that the  net proceeds  from this  Offering,
     together with  existing cash and  cash equivalent and  funds generated from
     on-going operations  will be sufficient to finance the Company's operations
     at least through 1997.   However, the Company may require additional  funds
     to support  its working capital requirements or  for other purposes and may
     seek to  raise  such additional  funds  through  public or  private  equity
     financing  or  from  other  sources.    No  assurance  can  be  given  that
     additional  financing  will  be  available  or,  if  available,  that  such
     additional  financing will  be on  terms favorable  to the  Company or  its
     shareholders.

     businesses  to  deploy and  scale  their solutions from  small, single-site
     networks to large,  multi-site  environments.
     

     Industry Background

              Overview.    Over  the  last  decade decentralized  computing  has
     emerged  as a  result  of the  widespread  adoption of  personal computers,
     local area  networks  ("LANs"), and  wide  area  networks ("WANs").    This
     emergence has enabled users to  communicate with each other and  share data
     throughout an entire organization.   With the recent popularization  of the
     Internet  and  increased performance  capabilities  offered  by  high-speed
     modems, ISDN  services  and Frame  Relay  technology,  the volume  of  data
     transferred over networks has increased dramatically.  

              In addition,  leading hardware  and software vendors  have adopted
     and  support   TCP/IP,   the  Internet's   non-proprietary   communications
     protocol,  for computer communications and information exchange.  This open
     platform,  along with  the  emergence of  the  Internet, allows  increasing
     numbers of businesses  and consumers to engage in electronic commerce, such
     as  home  banking,  credit  verification,  securities   trading,  and  home
     shopping.  

              Organizations are increasingly using  public networks, such as the
     Internet, as  an extension of  their enterprise networks.   Public networks
     offer a  cost-effective means of  connecting branch offices  and remote and
     mobile  users to mission critical applications and corporate resources such
     as  groupware, customer  databases, and inventory  control systems.   Also,
     the  Internet can  be  used  as a  lower  cost alternative  to  value-added
     networks  as  a means  to  link  companies  with  customers, suppliers  and
     trading  partners.    In  addition,  businesses  are  deploying  intranets,
     internal networks  using  TCP/IP  protocols, to  facilitate  geographically


                                          40
<PAGE>






     dispersed communications and the transmission of  information throughout an
     enterprise in a cost effective manner.  

              With  the  increased  use  of  the  Internet  and intranets,  many
     organizations are discovering  that network security  is a  key element  in
     successfully implementing distributed applications and services,  including
     electronic  mail,  electronic  data interchange,  electronic  commerce, and
     information  exchange services.   Information  becomes  more vulnerable  as
     organizations  rely  heavily  on  computer  networks   for  the  electronic
     transmission of  data.  In  the absence of  comprehensive network security,
     individuals and  organizations are  able to  exploit  system weaknesses  to
     gain   unauthorized   access  to   networks,  network   transmissions,  and
     individual  network computers.   These  individuals  and organizations  use
     such  access  to  alter  or  steal  data  or,  in  some  cases,  to  launch
     destructive attacks on data and computers within a network.  

              Demand for computer network  security products is expected to grow
     significantly  as  a result  of  the  increased  use  of the  Internet  and
     intranets.   The Yankee Group,  a market research  firm, indicated  that it
     expects the market for information  security products and services  to grow
     at a 70% compounded annual rate to the end of the  decade from $395 million
     in 1995 to $5.6 billion in the year 2000.

              Network  Security  Elements.   Each of  the following  elements is
     critical in creating  a complete network  security solution  to protect  an
     organization's data, network, and computer systems:

              .       Identification and Authentication -  Verifying the  user's
                      identity to  prevent unauthorized  access to computer  and
                      network resources. 

              .       Integrity  -   Ensuring  that  network  data,  whether  in
                      storage   or  transmission,   has  not   been  changed  or
                      compromised by any unauthorized manipulation. 

              .       Non-repudiation -  Verifying that  data transmissions have
                      been  executed between  specific  parties so  that neither
                      party may legitimately claim that the  transaction did not
                      occur.

              .       Authorization  -  Controlling  which  systems,  data,  and
                      applications a user can access.

              .       Encryption -  Preventing unauthorized  users from  viewing
                      private  data through  the  process of  "scrambling"  data
                      before  it   is  transmitted  or  placed  into  electronic
                      storage.

     To date,  network security  solutions have  focused on  single function  or
     point products  that address  one  or a  limited number  of these  specific
     security elements.


                                          41

              Network  Security Products.   Over the years a  number of security
     products  have  been  developed,  including  passwords, token-based  access
     devices,  firewalls,   encryption  products,   smart  cards,  and   digital
     certificates.   Each  of  these  products  was  designed  with  a  specific
     function or objective; however, few were designed to  meet all of the needs
     of enterprise-wide security.  Single  function or point products  that have
     been developed  to address one or a limited number of security requirements
     include the following:

                      Passwords and Tokens.  Until recently,  passwords were the
              most  common  method of  authentication.    Static  (non-changing)
              passwords were developed as the first attempt to address the  need
              for authentication.  Static  passwords, however, are inadequate as
              they are  susceptible to "sniffing" (unauthorized  viewing) and to
              attacks  using software  designed to  randomly generate  and enter
              thousands  of   passwords.    As  a   result,  dynamic  passwords,
              including single-use passwords, were  created to provide a greater
              level  of  authentication.     Dynamic  password   implementations
              include the use of  time-varying and challenge-response passwords.
              Generally, dynamic  authentication passwords require the  use of a
              hand-held,  electronic device  called a  hardware token.   Dynamic
              passwords  were  subsequently  strengthened by  incorporating two-
              factor   identification,   which  provides   a  higher   level  of
              authentication in that two  independent components are combined to
              identify a  user (for example, a  bank ATM card  and a  PIN code).
              However, dynamic  passwords and  two-factor identification provide
              only  a  limited  level  of  security  because  the  sessions they
              authenticate are still vulnerable to interception.

                      Firewalls.   Firewalls are network  access control devices
              that regulate the  passage of information based on  a set of user-
              defined rules.   Generally, firewalls  are based upon  one of  two
              technical architectures:    packet filters  (customarily  used  in
              routers)  and  proxy-based  application-level  gateways.    Packet
              filters  screen  network  traffic  and  allow or  prevent  network
              access  based  upon   source  and  destination  Internet  protocol
              addresses.   Proxy-based application-level gateways provide access
              to applications on the network only after the user has  identified
              the desired application and submitted a valid password.  

                      Encryption.    Encryption  products  provide  privacy  for
              transmitted  data.   Encryption algorithms  scramble data  so that
              only  users with  the appropriate  decoding key  are able  to view
              transmitted or  stored data.   Public-key encryption  has recently
              gained additional  credibility for managing the  keys (codes) used
              to encrypt, and subsequently decrypt user designated data.

                      Smart Cards.   Smart cards  are similar in  size to credit
              cards,  but contain  a  small, tamper-proof  microprocessor  chip,
              capable  of   storing  data  and   processing  complex  encryption
              algorithms.   Smart  cards  are an  advanced  authentication token
              that are also capable of storing information, such as credit  card

                                          42
<PAGE>






              or bank account numbers,  medical records, photographic images, or
              digital certificates.

                      Digital Certificates.  A digital certificate  serves as an
              individual's  electronic identification  card.    The certificates
              are  digitally   signed  by   a  trusted  third-party,   called  a
              certificate  authority,  who  vouches  for  the  identity  of  the
              certificate holder.   Digital certificates  are being standardized
              as a means  of authenticating on-line users, and are  perceived to
              be a key  technology for the expansion of secure  transactions and
              electronic commerce.

              As  businesses  increase  their  dependence  on the  Internet  and
     deploy intranets, the  Company believes that  there will  be an  increasing
     need for a comprehensive  enterprise-wide network security solution.   Many
     network  security vendors,  however, have  focused  on developing  products
     that  address   only  one  or   a  limited  number   of  specific  security
     requirements.   In addition,  products developed  by different  vendors are
     often difficult  to integrate  with  each other  and pose  interoperability
     problems.    Consequently,  the  Company  believes   that  businesses  will
     increasingly demand comprehensive network security solutions  that are easy
     to implement and  transparent to the user.   These solutions must  have the
     ability  to  integrate   with  existing   applications,  networks,   and/or
     mainframe  applications,  while  being  flexible  and  powerful  enough  to
     address the needs of newly developed applications.

     The V-ONE Solution

              The  Company  offers a  comprehensive  suite  of  network security
     products that  address  the  need  for  identification  and authentication,
     integrity,  nonrepudiation,  authorization,  and  encryption.  The  Company
     believes that, because of its unique combination of firewalls, smart cards,
     and  encryption  technology,  it  is the  first network  security vendor to
     provide two-factor identification, mutual authentication,  and fine-grained
     access  control.   This  combination of  network security  products enables
     organizations  to identify and authenticate network users while controlling
     access to network services. The Company's technology is designed to prevent
     unauthorized  access to an organization's mission critical applications and
     internal  data  without  impeding  permitted  uses  of  the  organization's
     resources and information.  The Company's products are compatible with many
     leading  hardware platforms  and operating  systems, as well as many third-
     party  security products, such  as firewalls.   The Company's customers are
     able  to integrate  V-ONE's  security  products into  their  networks  with
     minimal impact on existing systems and applications.

              The Company's suite of products can be combined and configured  to
     provide  perimeter   defense,  secure   remote  access,  and   intra/inter-
     enterprise   security  to  facilitate   secured  electronic   commerce  and
     information exchange.  The  Company's principal products  are SmartGATE,  a
     client/server   product  that  offers  identification  and  authentication,
     integrity, nonrepudiation, authorization, and encryption; and SmartWall, an
     application-level firewall that incorporates SmartGATE's functionality. The
     Company   provides   customers   with   two-factor  identification,  mutual
     authentication,  fine-grained  access control, and encryption by  combining

                                          43
<PAGE>






     SmartCAT, V-One's smart  card technology,  with the  SmartGATE  server.  In
     addition,  SmartGATE users  can  access  enterprise  networks  from  remote
     locations using SmartCAT.

              Network security solutions created using the Company's  technology
     enable its  customers  to securely  deploy a  broad range  of services  and
     applications  to  engage in  secured  electronic  transactions, information
     exchange,  and  remote  access  to  legacy  applications.    The  Company's
     technology is  designed to be  (i) modular, allowing  businesses to utilize
     the security product  or products best  suited to  address their  immediate
     needs, with a seamless migration  path to additional products  as required,
     (ii) scaleable,  ranging from a  single system supporting  several users to
     multiple systems  potentially supporting  hundreds of  thousands of  users,
     and (iii) portable,  employing smart  card technology  capable of  securing
     access independent  of  any  particular  user's machine  or  network  entry
     point.  

              Examples  of  network  security  solutions  created using  V-ONE's
     products include:

              Multi-purpose Smart  Cards.   A major telecommunications  company,
     under  a  reseller  agreement, is  using V-ONE  technology to  offer multi-
     purpose,  secure  campus card programs to  colleges and  universities.  The
     telecommunications  company is currently deploying that program at  a large
     university.   See "-  Strategic Alliances - Telecommunications."     At the
     university, the  Company's products have  been combined  to  provide secure
     access to the Internet and the university's internal network.  Students can
     use  smart  cards  to obtain  access to their university   records, student
     information,  and  campus  services via secure Internet access.   The smart
     cards also include stored value for use at on- and   off-campus vendors and
     pay telephones. In  addition, students can transfer  cash value  from their
     bank accounts to the smart cards by using advanced card  readers located on
     campus. The initial campus program began in  the spring of  1996, and it is
     currently  expected  that  the  program  will  be fully  implemented to the
     university's 30,000 students in the fall of 1996.

              Home   Banking.      Several  commercial   banks   are   deploying
     applications to  their customers that  utilize the Company's SmartGATE  and
     SmartWall  technology  to enable  secure,  cost-effective,  and  convenient
     Internet-based, home banking  services.  V-ONE's technology  is designed to
     allow a bank's customers to  securely transfer funds, review  accounts, and
     communicate with other  bank departments using  the Internet.   To  protect
     the  customer's privacy, all data  streams between a  bank customer and the
     bank's private network are  encrypted.  By using V-ONE's technology, a bank
     is  able  to  cost-effectively provide  secured  data  transmissions  while
     deploying applications  to its  customers that  are intended  to result  in
     higher  levels of  customer service  and convenience  to the  customer.  In
     some cases, the  Company's products augment a bank's existing private dial-
     up network system for home banking.   Historically, dial up solutions  have
     afforded  banks  quick  entry  into  the  home  banking  market,  but  such
     solutions  have   typically  had  certain   administrative  and   financial
     limitations.   

              Electronic Data  Interchange  ("EDI").    GE  InterBusiness ,  the
     secure  Internet  offering  of  GEIS,  a  worldwide  provider  of  computer

                                          44
<PAGE>






     communications services, is  designed to provide electronic  commerce, such
     as EDI,  and secured messaging,  as well  as access  to GEIS's  value-added
     network ("VAN")  over the Internet.  GEIS has  made this integrated product
     offering  available to  its installed  client base  of approximately 40,000
     corporations.  Using  SmartGATE, GEIS  has established an  environment that
     provides secure  data  transfer  over  the  Internet.   The  use  of  V-ONE
     technology permits GEIS'  business clients to conduct  electronic commerce,
     to share  business information via  bulletin boards, and  to take advantage
     of   the   Internet's   open   standards   while  maintaining   transparent
     authentication,   authorization,  and   encryption.     Each   time  a   GE
     InterBusiness member  engages in a transaction  using the  GE InterBusiness
     service, SmartGATE authenticates  the member, checks the member's  right to
     perform the transaction, and encrypts the session.

              Internet Services.   It  is expected that  Virtual Networks,  Inc.
     ("VNI")  will be the first Internet  service provider ("ISP") to deploy the
     Company's secured  messaging module  SmartREM (Smart Registered  Electronic
     Messaging),  which is expected  to be  introduced in  the third  quarter of
     1996.   SmartREM will couple  SmartGATE with a  SmartGATE-aware TCP/IP mail
     server to  enable secure  registered e-mail  over the  Internet.   SmartREM
     will provide a  mail system that authenticates  the identity of the  sender
     of each message, guarantees delivery of the message to only  the addressee,
     and will encrypt  the message  during transit  between the  sender and  the
     receiver to ensure privacy of the data stream.

     Strategy

              The   Company's  goal  is  to  become   the  leading  provider  of
     comprehensive, open, and  interoperable network security products  that are
     convenient  to the end  user.  The Company's  strategy to  realize its goal
     contains the following elements:

              SmartGATE  Server  and SmartGATE  Client.    SmartGATE  server and
     SmartGATE  client are  designed  to interoperate  easily  with most  TCP/IP
     based  applications and  to allow the  end-user to safely  use existing and
     future software applications  over the Internet and  intranets.   SmartGATE
     employs two-factor identification (two independent  components are combined
     to authenticate  a user)  and mutual  authentication (both  the server  and
     client determine  that the other party to the  transaction is authorized to
     participate in  the transaction)  through the  use of  virtual or  physical
     smart cards.   Two-factor identification and mutual authentication  are the
     foundation for  V-ONE's bulk encryption  technology and non-repudiation  of
     the user's session.

              Once  both  parties  to  a  communication involving  an  untrusted
     network have  been identified  and authenticated,  SmartGATE establishes  a
     secured, encrypted  link over the  untrusted network.   The authorized user
     is then granted access  to only those services and data for  which the user
     has been approved.   SmartGATE supports secure remote administration, which
     can  be accessed using  a Web browser or  telnet.   SmartGATE also supports
     the  data encryption  standard  ("DES") (which,  in  most forms,  cannot be
     exported  from  the  United  States  without  the  approval  of  the  State
     Department) and RSA's RC4 (which is exportable).  

              SmartGATE server  software versions are available  on a variety of
     leading operating systems, including Berkeley  Software Development, Inc.'s
     BSD/OS, Sun  Microsystems' SunOS, and  Hewlett-Packard's HP-UX.   SmartGATE
     client supports Microsoft's Windows versions  3.0 and 3.1, Windows  95, and
     Windows NT.  The Company  believes that SmartGATE server  software versions


                                          47
<PAGE>






     will also be commercially  available for Windows  NT and SunSolaris by  the
     end of the third quarter of  1996.  In addition, the Company believes  that
     SmartGATE client software versions will also  be commercially available for
     Apple Computer's  Macintosh by the  end of  the third quarter  of 1996.   A
     turnkey version  of SmartGATE  server is available  for BSD/OS on  an Intel
     Pentium hardware  platform.   The  Company  intends to  support  additional
     leading  hardware   and  software  platforms   based  on  specific   market
     opportunities.  

              SmartWall.  SmartWall, the  Company's firewall product, provides a
     high level of protection against  unauthorized access to a  trusted network
     from an untrusted network.   SmartWall also allows transparent  access from
     the trusted network  to services and applications on the untrusted network.
     SmartWall  includes  a  secured  graphical  user   interface  for  firewall
     administration,  strong  mutual  authentication  to   identify  users,  and
     complete  transparency for  authorized  traffic.   In  addition,  SmartWall
     allows multiple  sites to  be administered  from any  location using  a Web
     browser  or  telnet.    SmartWall  supports  multiple  types   of  standard
     encryption, authentication tokens, proxy services, and  secure transmission
     channels.    SmartGATE is  fully  integrated  into  every  SmartWall.   The
     SmartWall   firewall  incorporates   TIS's  Gauntlet(REGISTERED  TRADEMARK)
     kernel.

              SmartWall  software-only  versions are  currently  available  on a
     variety  of leading operating systems, including  BSD/OS, SunOS, and HP-UX.
     A SmartWall turnkey system is currently available  for BSD/OS.  The Company
     intends  to support  additional  leading  hardware and  software  platforms
     based on specific market opportunities.  

              SmartCAT.   The  SmartCAT product,  when  used with  the SmartGATE
     server,  provides two-factor identification and mutual authentication using
     physical smart card technology.   There  are three  parts  to  the SmartCAT
     product: (i) a standard smart card (ISO/IEC 7816-3, T=0 compliant), (ii)  a
     smart  card  reader  designed  by  the  Company, and  (iii)  the  Company's
     proprietary SmartGATE client software. Together these elementsprovide smart
     card-based encryption and authentication services. 

              Online Registration Service.  A user must be registered to  access
     an authentication-based  system.  The  Online Registration Service  product
     is a system  for efficient on-line  enrollment of  large user  communities.
     The  Online Registration  Service  completely  automates the  creation  and
     exchange  of the  user's  keys and  initializes  the user's  default access
     privileges.    The Online  Registration  Service either  creates  a virtual
     smart card or formats  a physical smart card that contains a  shared secret
     key that is PIN code protected.  

              SmartREM.    It is  currently  anticipated that  the Company  will
     introduce  SmartREM  in  the  third-quarter  of  1996.    When  introduced,
     SmartREM will provide  a private mail  box environment  for secured  e-mail
     over the  Internet or intranets.   SmartREM will  combine SmartGATE client,
     SmartGATE  server,  and  a  TCP/IP  mail  server,  enabling  individuals to
     initiate non-repudiable  sessions for  sending and receiving  authenticated

                                          48
<PAGE>






     messages within  the same  secured community.   SmartREM  will address  the
     concern of interception  or wrongful delivery  of private  or sensitive  e-
     mail  by  allowing  users  to  send  "registered"  e-mail.    For  example,
     businesses will  be able  to use  SmartREM to securely  send price  quotes,
     volume discounts, and  other sensitive  information over the  Internet from
     remote locations.

              Wallet Technology.   Wallet Technology  enables secured electronic
     credit card  payment transactions  over untrusted  networks, including  the
     Internet.   Wallet Technology encrypts the credit card information supplied
     by the purchaser and  forwards that information to the vendor.   The vendor
     adds  the purchase  value  to the  encrypted  credit card  information, and
     sends  all of this  information to the  credit card  issuer/processor.  The
     issuer/processor decodes this information and either  authorizes or rejects
     the purchaser's  request.  The Company's  design does not allow  the vendor
     to view the  unencrypted credit card information supplied by the purchaser.


              NetChart.   NetChart is a stock  performance analysis application.
     This  application was  originally developed  to  demonstrate the  Company's
     technology.   Recently, prospective and  existing customers have  expressed
     interest in using this application.

              Network  Security  Consulting.    The  Company's consulting  staff
     provides pre- and  post-sales support, vulnerability  analysis, performance
     analysis,  systems integration,  and system  security architecture support.
     The  Company's  consulting  staff   also  provides  fee-based   engineering
     services.   The Company  believes that  maintaining a  staff of  nationally
     recognized  consultants greatly  enhances  its  position as  an  innovative
     supplier of network security products.

     Technology

              The Company believes that  its technology and product architecture
     provide it with  an important competitive  advantage.   The cornerstone  of
     the  Company's  network  security solution  is  its  proprietary  SmartGATE
     client/server   security   product.       SmartGATE   enables    two-factor
     identification, mutual  authentication and fine-grained access  control for
     most  TCP/IP  client/server  applications.    Using  SmartGATE  technology,
     organizations   can   employ   two-factor    identification   and    mutual
     authentication to identify  and authenticate a user's access to the network
     while fine-grained  access  control confines  each  user's access  to  only
     those services to which the user is entitled.

              Two-Factor Identification.  Two-factor identification  employs two
     independent   components  to  identify  a  user  using  an  identity  token
     contained in  a physical  or virtual smart  card.   The information in  the
     physical or virtual smart card is  secured by a PIN code that is set by the
     user and is  not known  by anyone else.   SmartCAT  provides the means  for
     accessing and using  smart cards via smart card  readers.  SmartGATE client
     provides  the means  for  using virtual  smart  cards.   Both physical  and
     virtual smart cards store information  about the user including  the user's

                                          49
<PAGE>






     keys,  which  are  used  for   authentication.    The  keys   also  contain
     information that allow the SmartGATE  client to authenticate the  SmartGATE
     server with which it communicates. 

              Mutual Authentication.   Mutual authentication employs  a dual set
     of challenges  and encrypted  responses that  interact to  enable both  the
     client and the server to determine that the other party to the  transaction
     is  authorized  to participate  in  the  transaction.   SmartGATE's  mutual
     authentication employs dual challenges coupled with  encrypted responses to
     ensure  non-repudiation   between  the   two  parties   to  an   electronic
     transaction.  When a client application attempts to make a  connection with
     an  application service  protected  by a  SmartGATE  server, the  SmartGATE
     client  first performs  a mutual authentication  process with the SmartGATE
     server  protecting the  application  service.   During  the  authentication
     process, the  SmartGATE server sends  a challenge to  the SmartGATE client,
     and the SmartGATE  client uses the secret  keys on the physical  or virtual
     smart  card to correctly  respond to  the challenge.   The SmartGATE client
     also  sends a challenge to  the SmartGATE server,  and the SmartGATE server
     must  prove to  the client that  the server is  the issuer  of the client's
     secret key.

              Fine-Grained Access Control.   Fine-grained access control employs
     access control lists to compare  an identified user's request  for services
     against  a list  of entitlements  to determine  whether  to grant  the user
     access to the requested service.   SmartGATE employs an access control list
     to define the specific Web content  page,  file,  or  host application that
     identified  users are permitted  to use.  If  SmartGATE determines that the
     user is permitted  to access the requested service,  then the connection is
     passed  through the  SmartGATE server to  the requested  service, otherwise
     the connection is dropped.

              In  addition  to  providing  identification,  authentication,  and
     access control,  the SmartGATE client  and server  independently compute  a
     session  key for encrypting the current TCP/IP data stream.  The encryption
     key is  computed based on  information exchanged during the  authentication
     process and is never transmitted over the network.

     Strategic Alliances

              Telecommunications.   A major telecommunication   company is using
     the Company's technology to offer multi-purpose secure campus card programs
     to colleges and universities.  The Company has appointed  and  the telecom-
     munications  company has agreed to act as the Company's  exclusive reseller
     of the Company's SmartGATE, SmartWall, and SmartCAT products for resale and
     distribution  to colleges and universities.  The telecommunication  company
     is currently deploying  this  program at  a large university.   See  "- The
     V-ONE  Solution - Multi-purpose Smart  Card."   The  Company believes  that
     the telecommunication  company intends to promote this  technology at other
     campuses at which it has preexisting  relationships;  however, there can be
     no  assurance  that  any additional campuses  will adopt this technology in
     whole or in part.

     SmartGATE  product and  Software.com's Post.Office  product.   The  Company
     believes that the  integration of SmartGATE and  Software.com's Post.Office
     product  will  provide  Internet users  with  the  ability  to  communicate
     efficiently, effectively, and securely.   Presently, e-mail  communications
     over the Internet are not secure.  The  sender cannot ascertain whether the
     intended receiver,  in fact, received  the message and  the receiver cannot
     authenticate the actual  identity of the  sender.   The strategic  alliance
     with   Software.com   combines  the   Company's   SmartGATE   server   with
     Software.com's Post.Office  product so that  the Post.Office server,  using
     SmartREM, authenticates each  sender by means of  two-factor identification
     and  mutual authentication  (similar  to the  technology  used by  bank ATM
     machines to  dispense cash) and  guarantees delivery only  to the specified
     addressee.  In  addition, the Post.Office  product will  notify the  sender
     when the addressee has retrieved the message (return receipt requested).

              The Software.com  agreement expires on July 19, 1996; however, the
     agreement provides  for the  automatic renewal  for successive three  month
     terms.  The  agreement may  be terminated for  cause by  either party  upon
     thirty days' prior written notice.

     Sales and Marketing

              The  Company markets  its  network security  products  through its
     direct  sales force and,  to a lesser extent,  through systems integrators,
     value-added   resellers  ("VARs")  and  international  distributors.    The
     Company is  currently seeking to expand  its sales and marketing  staff and
     intends  to   devote  additional  resources   to  marketing  and   business
     development  activities in  order to  expand  its third-party  distribution
     channels.

              Direct  Marketing  Effort.    The  Company  has  concentrated  its
     initial  marketing and direct  sales efforts  on key  industry participants
     within   certain  industry   and  market   segments,  including   financial
     institutions, information services companies, and government agencies.  The
     Company employs a  direct sales force to  market its products to  these key
     industry  participants.     The  Company's  direct  sales   force  solicits
     prospective  customers  and  provides technical  advice  and  support  with
     respect  to  the Company's  products.   As  of  May 31,  1996,  the Company
     employed  ten  direct   sales  representatives.    In  1996,   the  Company
     anticipates  hiring additional  direct  sales representatives  and  opening
     regional sales offices in select cities.  

              Indirect  Marketing  Effort.     An  important  component  of  the
     Company's  sales  strategy is  the development  of indirect  sales channels
     such  as  ISPs,  systems  integrators,  and   value-added  network  service
     providers.   The Company  utilizes indirect sales channels  to leverage the
     efforts of its  direct sales force.  For  example, in the secured messaging
     market, the Company has targeted ISPs like VNI.   The Company has initiated
     sales and  marketing programs  to sign  up integrators, VARs,  and original
     equipment manufacturers within the United States.  As of June 7, 1996,  the
     Company  had established  relationships with  four  integrators within  the
     United  States  and  has  signed  VAR  agreements  with  GEIS  and  a major
     telecommunication  company. As of June 7, 1996, the Company has established
     relationships  with  international  distributors  in  the  United  Kingdom,
     Sweden,    Germany,    Belgium,   South  Africa,  and  Australia, including
     relationships   with  Internet  Solutions,  Ltd. in  the United Kingdom and
     PromaCom A.B. in Sweden.

              Strategic  Alliance Development.   The  Company plans  to increase
     market   penetration  by   developing  and   capitalizing  upon   strategic
     alliances.  These alliances are  intended to increase the distribution  and
     market acceptance  of V-ONE's  network security products  in markets  where
     direct  sales  and  traditional   indirect  sales  efforts  are  not   cost
     effective.  For  example, the Company  has developed  a strategic  alliance
     with  a  large   telecommunication   company  to  offer  to  colleges   and
     universities  a multi-purpose,  secure campus card program  that integrates
     V-ONE   technology   with  the   telecommunication  company's  products and
     services.   The Company  has also  entered into a  strategic alliance  with
     Software.com that is  designed to allow secure messaging over the Internet.
     The  Company  intends  to  continue  efforts  to  strengthen  its  existing
     relationships  while  also  forging new  relationships  with  key  industry
     participants.

     Customer Service and Support

              The  Company   believes   that  customer   support   and   product
     maintenance  is critical  to retaining  existing  customers and  attracting
     prospective customers.   The Company provides on-site  installation support
     and basic administrator training  with each turnkey hardware  product sale.
     Each  such turnkey product comes with  24 hours a day,  seven days per week
     hardware and software support  for 90 days.  Upon expiration of  the 90-day
     period, customers may purchase an  annual maintenance plan.   Purchasers of
     the  Company's  software  products may  also  purchase  annual  maintenance
     plans.   The  annual maintenance  plan  provides  customers access  to  the
     Company's customer service line, technical support  personnel, and software
     upgrades.

              The Company  provides additional  user or  administrator training,
     on-site support,  vulnerability  analysis,  performance  analysis,  systems
     integration,  and  system  security architecture  support  as  an  optional
     service  through its consulting staff.   Additionally, the Company provides
     customer support  services for  those customers  who have  entered into  an
     evaluation agreement with the Company.

              The  Company  intends to  enhance  its  existing  customer service
     system  by adding  a  toll-free line  and  developing a  three-tier support
     system.   The first tier of the  Company's enhanced customer support system
     will consist of help  desk support personnel accessing customer information
     and a problem database.  Second tier support  for elevated problems will be
     provided by  the  Company's existing  systems engineering  staff.   Lastly,
     critical third  tier problems will  be addressed by  the Company's in-house
     consulting  staff.   The  Company  believes  that  moving  to a  three-tier
     customer support system will increase its  effectiveness and responsiveness
     to meeting customer's expanding needs.

     Product Development

              The Company  is expanding and  intends to continue  to expand  its
     existing  product offerings to meet  existing and evolving network security
     needs of businesses  and organizations.  The Company's products and product
     enhancements are  developed in response to  customer needs.   Compatibility
     and interoperability  with other applications  are strategic focuses of  V-
     ONE's product  development efforts.   The  Company intends  to continue  to
     monitor  emerging standards  for  networking and  security,  and adapt  its
     suite  of products  to  encompass these  standards.   In  keeping with  the
     Company's customer-driven product strategy,  the Company will also focus on

                                          53
<PAGE>






     developing  business   partnerships  with  other  companies   that  provide
     security related services, and exploiting new market opportunities.

              The market  for the  Company's  products  is dynamic  and  rapidly
     changing.   The Company  believes that its future  success will depend upon
     its  ability  to:  (i) enhance its  existing  products,  (ii) identify  new
     opportunities  to  leverage  existing technologies,  and  (iii) develop new
     technologies   resulting   in  new   products,   markets,   and   services.
     Accordingly,  the  Company  expects  to  continue  to  make  a  significant
     investment  in  research  and development,  product  market  analysis,  and
     systems  integration.    The  Company  believes  that  its  customer-driven
     development strategy  will enable  it to  continue to  broaden its  product
     offerings.  

              As  of May  31, 1996,  the Company  employed 8  full-time software
     developers, and 3 software project managers.

     Competition

              The  market   for  network  security  products   and  services  is
     intensely competitive.   The  Company expects  competition to intensify  in
     the future.

              Currently,  the  Company competes  in  several  different markets:
     Internet and  intranet perimeter  defense and  access control  (firewalls),
     token   authentication,  smart   card-based   security  applications,   and
     electronic commerce applications.  The Company's  principal competitors for
     Internet  and  intranet  perimeter defense  include  Advanced  Network  and
     Services  (a  subsidiary  of America  Online,  Inc.),  Bay  Networks, Inc.,
     Border  Network Technologies,  Inc.,  Check Point Software Technology Ltd.,
     Cisco  Systems,  Inc.,  Digital  Equipment   Corporation,  Harris  Computer
     Systems Corporation, International Business  Machines Corporation, Milkyway
     Networks  Corporation,  Morningstar  Technologies,  Inc.,  Network  Systems
     Corporation,  Raptor  Systems,  Inc.,  Secure  Computing  Corporation,  Sun
     Microsystems, Inc., and TIS, which owns  the Gauntlet(TRADEMARK) kernel and
     licenses it to the Company.

              The  Company  competes  to a  lesser  degree  with  token  vendors
     because  the  Company's  SmartGATE product  supports  many  vendor  tokens.
     Token   vendors   include  Security   Dynamics,  Digital   Pathways,  Inc.,
     CRYPTOCard  Inc.,  Leemah  DataCom  Security  Corporation,  Racal-Guardata,
     Inc., and  National  Semiconductor Inc.    Security Dynamics  has  recently
     agreed to acquire  RSA.  RSA's technology  is licensed to and  incorporated
     within certain products  of the  Company.  As  a result, Security  Dynamics
     may become a more substantial competitor of the Company.

              For   smart   card-based   security   applications,  the   Company
     principally competes with  those token vendors listed above who offer smart
     card technology.

              The  Company's  principal  competitors   in  electronic   commerce
     applications are Netscape  Communication's Secure Socket Layer  (SSL), Open

                                          54
<PAGE>






     Market Inc.'s  Secure HTTP (S-HTTP),  and Cylink Corporation's  transaction
     software.  

              Because of the  rapid expansion  of the  network security  market,
     the Company will  face competition from existing and new entrants, possibly
     including the  Company's customers, suppliers, and/or resellers.  There can
     be no assurance  that the Company's  competitors will  not develop  network
     security products that may  be more effective than the Company's current or
     future products or that the  Company's technologies and products  would not
     be rendered obsolete by such developments.

              Many  of  the Company's  current  and  potential  competitors have
     longer  operating  histories, greater  name  recognition,  larger installed
     customer  bases,  and  significantly  greater  financial,  technical,   and
     marketing  resources than the  Company.  As a  result, they may  be able to
     adapt more quickly to new or emerging technologies and  changes in customer
     requirements, or to  devote greater resources to the  promotion and sale of
     their products,  than the  Company.   There can  be no  assurance that  the
     Company's customers will  not perceive the products of such other companies
     as substitutes for the Company's products.

              The  Company  believes  that  the  principal  competitive  factors
     affecting the market  for network security products  include effectiveness,
     scope of product offerings,  technical features, ease of  use, reliability,
     customer service  and support,  name  recognition, distribution  resources,
     and  cost.   Current  and potential  competitors  have established,  or may
     establish in the future, strategic  alliances to increase their  ability to
     compete  for the  Company's  prospective  customers.   Accordingly,  it  is
     possible that new competitors or  alliances may emerge and  rapidly acquire
     significant  market  share.   Increased  competition  may result  in  price
     reductions, reduced  gross margins, and  loss of market  share, which would
     materially  adversely affect the  Company's business,  financial condition,
     and results of operations.  See "Risk Factors - Competition."


     Backlog

              Orders  for the Company's products are usually placed by customers
     on an  as-needed basis  and the  Company has  typically been  able to  ship
     products within 30 days after  the customer submits a firm  purchase order.
     The Company  does  not  generally  maintain long-term  contracts  with  its
     customers  that  require  customers to  purchase  the  Company's  products.
     Accordingly, the  Company  has  not maintained,  and  does  not  anticipate
     maintaining, a  backlog.  See  "Risk Factors -  Anticipated Fluctuations in
     Quarterly  Results," "-  Long  Sales Cycle;  Seasonality,"  and "-  Risk of
     Defect and Development Delays."

     Supply Sources  

              Components  used  in   the  Company's  network  security  products
     consist  primarily  of  computer  diskettes  and  computer  magnetic  tapes
     purchased from  commercial  vendors.   Components  used  in  the  Company's

                                          55
<PAGE>






     turnkey SmartWall and  SmartGATE server products consist  primarily of off-
     the-shelf computers,  memory,  displays,  power supplies,  and  third-party
     peripherals (such as hard drives and network interface cards).  

              The Company has agreements with  at least two vendors for  each of
     its parts and components.   However, the Company orders most of each of its
     parts and components from a  single vendor to maintain quality  control and
     enhance working  relationships.  The  Company obtains most  of the hardware
     for its  turnkey systems from  Beltron Computers, a  subsidiary of DBA  MAX
     Technology Corp.  The Company  uses smart card readers manufactured by  two
     contract manufacturers based on the Company's design specifications.  

              While  the Company  believes  that alternative  sources  of supply
     could be  obtained, the Company's inability  to develop alternative sources
     if  and as required in  the future could result  in delays or reductions in
     product shipments  that  could  have  a  material  adverse  effect  on  the
     Company's business, financial condition, and results of operations.  

     Regulation and Government Contracts

              The  Company's information  security products  are subject  to the
     export  restrictions administered  by the  U.S. Department  of State, which
     permit the export of  encryption products only  with the required level  of
     export  license.   For example,  there are  two  versions of  the SmartGATE
     client; one supports DES for bulk encryption and can only be exported  from
     the United States for  financial transactions.  The other supports  RC4 (an
     encryption algorithm) for  bulk encryption and is exportable.  In addition,
     these U.S.  export laws  prohibit the  export of  encryption products  to a
     number of hostile  countries.  Although to  date the Company has  been able
     to  secure all  required U.S. export  licenses, there  can be  no assurance
     that  the Company will  continue to  be able to  secure such  licenses in a
     timely  manner in the future, or at all.  See "Risk Factors - Risk of Sales
     to U.S. Government," "- International  Sales," and "- Effect  of Government
     Regulation of Technology Exports."

              In  certain  foreign  countries,  the  Company's distributors  are
     required  to  secure  licenses  or  formal   permission  before  encryption
     products can be imported.   To date, except for certain limited  cases, the
     Company's  distributors  have not  been  denied  permission to  import  the
     Company's products.  

     License Agreements

              Trusted   Information  Systems,  Inc.  ("TIS")   Agreement.    The
     Company's license agreement  with TIS  requires the  Company to  pay a  fee
     (which varies based on the  number of units licensed) for each unit  of the
     Gauntlet(TRADEMARK)  product licensed  for use in  SmartWall.   The license
     expires  on December  31,  1996; however,  the  agreement provides  for the
     automatic  renewal  of the  Company's license  rights for  successive three
     year terms.  Either  party may terminate the agreement upon the  default of
     the other party  if the  defaulting party has  failed to  cure the  default
     within 30  days of the  receipt of  written notice of  default.   See "Risk

     Factors - Dependence on  Key Licensing  Agreements, External Resources  and
     Suppliers." 

              RSA  Data  Security,  Inc.   ("RSA")  Agreement.    The  Company's
     SmartCAT and  Wallet Technology  software incorporate  data encryption  and
     authentication technology  owned  by RSA.    The  Company has  a  perpetual
     license  agreement with  RSA,  which became  effective  as of  December 30,
     1994.    On May  23,  1996,  RSA  exercised  an option  granted  under  the
     agreement to convert its right to receive  future royalties into 2% of  the
     Company's  outstanding  voting  securities,  after  giving  effect  to  the
     issuance to  RSA, until the date of  the Company's initial public offering.
     Pursuant to a  separate agreement between RSA  and MIT, MIT is  entitled to
     receive  a portion of  any royalties that  RSA receives.  As  a result, the
     Company will issue directly to MIT  a portion of the shares of Common Stock
     to  which RSA  is  entitled  under the  RSA  Agreement.   The  Company  has
     reserved a total of 280,812  shares of Common Stock to be issued to RSA and
     MIT immediately prior  to consummation of  the Offering.  Either  party may
     terminate  the  agreement upon  the  default  of  the  other party  if  the
     defaulting party  has failed  to cure  the default  within 30  days of  the
     receipt of written notice of  default.  RSA has announced that RSA  will be
     acquired by Security  Dynamics.  There is  no assurance that the  change in
     control   of  RSA   will  not  adversely   affect  the  Company's  business
     relationship with  RSA.  See  "Risk Factors  - Dependence on  Key Licensing
     Agreements, External Resources and Suppliers" and  "- Intellectual Property
     Rights; Infringement Claims."  

     Patents, Proprietary Technology, Trademarks and Licenses

                The  Company relies  on trademark,  copyright, patent  and trade
     secret laws, employee and third-party non-disclosure  agreements, and other
     methods to protect its  proprietary rights.  The Company has  pending three
     patent  applications with  the  United States  Patent and  Trademark Office
     that cover certain aspects of its technology.  Prosecution of  these 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 or that any future  patents will
     not be challenged,  invalidated or circumvented, or that the rights granted
     thereunder  will provide competitive advantages  to the  Company.  Further,
     the Company has not pursued patent protection outside  of the United States
     for the technology covered by two of the  pending patent applications.  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's  success  is  also  dependent  in  part  upon   its
     proprietary software  technology.   There  can  be  no assurance  that  the

                                          57
<PAGE>






     Company's  trade   secrets  or   non-disclosure  agreements  will   provide
     meaningful protection  for the Company's  proprietary technology and  other
     proprietary information.   In addition, 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.   Further,  there can  be no  assurance that  others
     will  not  independently  develop similar  technologies  or  duplicate  any
     technology developed by the Company  or that the Company's  technology will
     not  infringe upon  patents,  copyrights,  or other  intellectual  property
     rights owned by others.

              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
     manufactured or  sold abroad  may not  be protectable  in 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 overlaps,  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
     effectively  develop,  produce  and market  commercially  viable  products.
     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.

              There has been, and the  Company believes that there may be in the
     future, significant litigation in  the industry regarding patent  and other
     intellectual property  rights.  Although  the Company is  not currently the
     subject  of  any  intellectual  property  litigation, litigation  involving
     other  software developers,  including  companies  from which  the  Company
     licenses certain  technology, could have  a material adverse  affect on the
     Company's business,  financial condition, and results  of operations.   See
     "Risk Factors - Intellectual Property Rights; Infringement Claims."

     The Board of Directors and Board Committees

              The  business of the  Company will be managed  under the direction
     of  the  Company's Board  of  Directors.    The  Company's Restated  Bylaws
     authorize a  seven-member  Board of  Directors.    Currently the  Board  of
     Directors consists of 3 directors.   The Company's Restated  Certificate of
     Incorporation provides for  a classified Board of Directors effective as of
     the Company's annual meeting of  shareholders in June 1996.  In  accordance
     with the  Restated Certificate of Incorporation, the  terms of the Board of
     Directors will be divided  into three classes:  Class I  will expire at the
     annual meeting of shareholders to be held  in 1997, Class II will expire at
     the  annual meeting of shareholders to be  held in 1998, and Class III will
     expire at the annual meeting of shareholders to  be held in 1999.  At  each
     annual meeting of  shareholders beginning with the 1997 annual meeting, the
     successors  to directors whose  terms will  then expire will  be elected to
     serve until the  third annual meeting  following election  and until  their
     successors  have   been  duly  elected  and   qualified.    Any  additional
     directorships resulting  from an increase  in the number  of directors will
     be distributed among the three classes so that as nearly as possible,  each
     class  will  consist  of  an  equal  number  of directors.    The  Restated
     Certificate of  Incorporation and  Restated Bylaws provide  that a director
     may be removed at any time, but only for cause and only by  the affirmative
     vote of 67% or more  of the outstanding shares  of the Company entitled  to
     vote  at an  election of  directors at  a special  meeting of  shareholders
     called for that purpose.  

              The  Company's  Board  of   Directors  has  established  an  Audit
     Committee (the "Audit Committee")  to recommend the firm to be appointed as

                                          62
<PAGE>






     independent  accountants  to  audit financial  statements  and  to  perform
     services related to  the audit, review the  scope and results of  the audit
     with  the   independent  accountants,  review   with  management  and   the
     independent  accountants  the  Company's  year-end  operating  results, and
     consider the adequacy  of the internal  accounting procedures.   The  Audit
     Committee will  consist  of  at  least  2 directors  neither  of  whom  are
     employees of the Company.

              The  Company's   Board  of   Directors  has  also   established  a
     Compensation  Committee (the  "Compensation  Committee") and  an  Executive
     Committee (the "Executive  Committee").  The Compensation  Committee, which
     consists  of   2  directors,  reviews   and  recommends  the   compensation
     arrangements for  all directors  and officers,  approves such  arrangements
     for other  senior level  employees, and  administers and  takes such  other
     action  as may  be  required in  connection  with certain  compensation and
     incentive plans  of the Company.   The Executive  Committee, which consists
     of 2 directors, addresses significant corporate,  operating, and management
     matters between meetings of the full Board of Directors.

              The  Company intends to  seek election of at  least two additional
     directors who are  neither officers nor employees  of the Company prior  to
     consummation of the Offering.

              Option Grants.   James F. Chen, the Company's President  and Chief
     Executive Officer,  does not currently hold, nor has  he ever been granted,
     options to purchase the Company's Common Stock.

     Stock Option Plans

              1995 Non-Statutory Stock Option Plan

              In  May  1995,  the  Company  adopted  the  Virtual  Open  Network
     Environment Corporation 1995 Non-Statutory Stock Option  Plan ("1995 Plan")
     under which stock options may be awarded  to key employees of the  Company.
     It  is  expected that  the  1995 Plan  will  be ratified  by  the Company's
     shareholders  at the 1996 annual  meeting to be held on  June 28, 1996.  As
     of June 12, 1996, 8 employees and  1 former employee received awards  under
     the 1995 Plan.

              Stock  Option  Awards.   Stock  options  ("Non-Qualified Options")
     that do not  meet the requirements of  Section 422 of the  Internal Revenue
     Code of 1986,  as amended ("Code") are  available for grant under  the 1995
     Plan.    The  term  of  each Non-Qualified  Option  is  determined  by  the
     committee of the Board of Directors that administers the 1995 Plan, but  no
     option is exercisable more than ten years after the date of grant.   Unless
     otherwise  provided  in  an  employee's   option  agreement,  Non-Qualified
     Options granted  under the  1995 Plan  expire ten  years from  the date  of
     grant and  are exercisable in  three equal installments  over a twenty-four
     month period.   Non-Qualified Options  also may be  subject to restrictions
     on exercise, as determined by the Committee.  

              The exercise price  for Non-Qualified Options may be no  less than
     par value per  share.  The exercise price  is payable by either a  check in
     the amount of  the purchase price or  by previously owned shares  of Common
     Stock with a market value equal to the purchase price.  

              Non-Qualified  Options  granted  under   the  1995  Plan  are  not
     transferable  by  the  Optionee  during  an employee's  lifetime.    Unless
     otherwise  provided  in  the  employee's  option  agreement,  Non-Qualified
     Options  will be  exercisable  within three  months  of any  termination of
     employment.

              Duration of  the Plan; Share  Authorization.  The  1995 Plan  will
     remain  in effect  until May  15, 2005,  unless terminated  earlier by  the
     Company's  Board of  Directors.   Awards have  been issued with  respect to
     528,444  shares of  Common Stock.   Such  shares  of Common  Stock have  an
     aggregate market  value of $3,170,664  based on the  initial offering price
     of $6.00.  

              On June  12, 1996, the  Board determined that  no further  options
     would be granted under the 1995 Plan.

              1995  Plan Administration.   The 1995 Plan is  administered by the
     Compensation Committee  of  the  Board.    The  1995  Plan  authorizes  the

                                          64
<PAGE>






     Compensation Committee to  grant Non-Qualified Options to  key employees to
     purchase  up  to  528,444 shares  of  Common  Stock  and  to determine  the
     employees to  whom Non-Qualified  Options will  be granted,  the number  of
     shares  subject  to  each  Non-Qualified  Option   and  applicable  vesting
     schedules. 

              The  members of  the Committee  are appointed by  the Board.   The
     Committee  must be  comprised of  at least  two  members.   Members of  the
     Committee are eligible  to receive options  under the  1995 Plan,  provided
     that such members  do not participate in  the decision to grant  themselves
     options.

              Transferability; Repurchase Right.   Each employee who receives an
     award under  the 1995  Plan is  prohibited from  transferring or  otherwise
     disposing of  the underlying  shares of  Common Stock until  180 days  have
     elapsed  following  such time  the  Company has  consummated  the Offering.
     However, shares of  Common Stock may be  used to pay the exercise  price of
     Non-Qualified Options.

              Upon  an employee's  termination of  employment with  the Company,
     the Company has the right to repurchase any or all of  the shares of Common
     Stock issued to  the employee with respect to Non-Statutory Options granted
     under the  1995 Plan, whether  then held by  the employee or a  transferee.
     The Company's  right to repurchase  shares of Common  Stock terminates once
     the Offering is consummated.

              Termination  and Amendment.   The  1995  Plan  may be  terminated,
     modified or amended  by the Company's shareholders.   Although the Board of
     Directors may terminate,  modify or amend the  1995 Plan to conform  to any
     change in  law  or regulation,  the  Board of  Directors  may not,  without
     shareholder  approval, (i)  increase  the maximum  number  of shares  as to
     which Non-Statutory Options may be granted under the  Plan; (ii) change the
     class  of employees  eligible to  be  granted Non-Qualified  Options, (iii)
     increase the periods during which  Non-Qualified Options may be  granted or
     exercised, or  (iv) provide for  the administration  of the  Plan by  other
     than the Committee.  No  termination, modification or amendment may be made
     to the 1995 Plan  without the consent of any employee whose rights would be
     adversely affected thereby.  

              Awards  Made.   As  of  June 12,  1996, Non-Qualified  Options  to
     purchase 526,444  shares of  Common Stock  are outstanding  under the  1995
     Plan.

              1996 Non-Statutory Stock Option Plan

              The  Company's   1996  Non-Statutory  Stock  Option   Plan  ("Non-
     Statutory  Plan") was adopted  by the Board of  Directors on April 4, 1996.


                                          66
<PAGE>






     The Non-Statutory  Plan  provides for  the  grant  of options  to  purchase
     Common  Stock subject  to  certain  restrictions on  transfer  ("Restricted
     Stock").   The  Non-Statutory Plan  expires  on  December 31, 1996  and  is
     administered by the  Non-Statutory Stock Option Plan Committee of the Board
     of Directors.   The purchase price per  share under each option  granted is
     an amount  equal to the  fair market value  of the underlying  share on the
     date  the option is granted.   Each option  granted under the Non-Statutory
     Plan is exercisable during  the period beginning on the date the  option is
     granted  and ending on December  31, 1996.  As of  May 15, 1996 all options
     granted  under the  Non-Statutory Plan  had been  exercised and a  total of
     575,951 shares of Restricted Stock had been issued. 
      
              In connection with  their exercise  of options  granted under  the
     Non-Statutory Plan,  the optionees,  including certain  executive officers,
     paid the par value  of the Restricted Stock in cash and executed promissory
     notes  in favor of the Company  as consideration for the remaining purchase
     price of the  Restricted Stock.  See  "Certain Transactions."  Five  of the
     six  optionees have executed promissory  notes with terms  of 10 years that
     are secured  by  the Restricted  Stock  purchased  therewith, bearing  a  6
     percent per  annum  interest  rate,  with  installments  of  principal  and
     interest  due  annually.   One of  the  optionees has  executed  a one-year
     promissory note, bearing a 6 percent per annum interest rate,  with payment
     of principal and interest  due at the  expiration of the promissory  note's
     one-year term. 

              Each optionee  may make  payments  to the  Company to  reduce  the
     principal  amount of his  or her promissory note  with the Restricted Stock
     serving as collateral  therefor; however, if the fair  market value of such
     consideration   is  less   than  the  then   outstanding  portion   of  the
     indebtedness being satisfied therewith, each promissory  note provides that
     the optionee bears personal liability  for the disparity.   Each promissory
     note may be prepaid without penalty.

              The  Restricted  Stock may  not  be  sold,  assigned, transferred,
     pledged or otherwise disposed of for six  years from the date the option to
     purchase the shares  was granted.  As  long as this restriction  remains in
     effect, no holder of Restricted Stock has the right to vote the  restricted
     shares for any purpose.   All voting rights with respect to  the Restricted
     Stock  are to be  exercised by a  majority vote of the  Board of Directors.
     The restrictions lapse 180 days  after the consummation of the  Offering or
     the acquisition of the Company in exchange for publicly traded shares.  

              On  June 12,  1996,  the Company's  Board of  Directors determined
     that no further options will be granted under the Non-Statutory Plan.

              1996 Incentive Stock Plan

              On June  12, 1996, the  Board of Directors of  the Company adopted
     the Virtual Open Network Environment Corporation 1996  Incentive Stock Plan
     ("1996 Plan"), under which both options and restricted share awards may  be
     made to the Company's  key employees and consultants.  Under the 1996 Plan,
     automatic stock option  awards are made to  non-employee directors.   It is

                                          67
<PAGE>






     expected  that the 1996 Plan will be ratified by the Company's shareholders
     at the 1996 annual meeting to be held on June 28, 1996.

              Awards Available  Under the 1996  Plan.  Awards  to key  employees
     and  consultants under  the  1996 Plan  may  take the  form  of both  stock
     options and  restricted  share awards;  however,  no employee  may  receive
     awards with respect  to more than 750,000 shares  of Common Stock under the
     1996  Plan.    As  of May  31,  1996,  approximately  52  employees  and  1
     consultant were  eligible to receive  awards under the  1996 Plan.   Awards
     under the  1996 Plan  may be  granted alone  or in  combination with  other
     awards.   Non-employee directors may  only receive non-discretionary  stock
     option awards (described in more detail below) under the  1996 Plan.  As of
     May 31, 1996,  none of the Company's directors were eligible to participate
     in the 1996 Plan.

              Stock Options.  Stock  options ("Incentive Stock Options") meeting
     the requirements of Section  422 of the Code and stock options  that do not
     meet such  requirements ("Non-Qualified  Options") are  both available  for
     grant under the 1996 Plan.   The term of each option will  be determined by
     the committee that administers the  1996 Plan ("Committee"), but  no option
     will be exercisable more  than ten years after the date  of grant.  Options
     will  also be  subject  to restrictions  on exercise,  such as  exercise in
     periodic installments, as  determined by the Committee.  The exercise price
     for an  Incentive Stock Option  must be at  least 100%  of the fair  market
     value of a share of Common Stock on the date of  grant of such option (110%
     in the case  of Incentive Stock Options  granted to a shareholder  who owns
     in  excess of  10% of  the Company's voting  stock).   There is  no minimum
     exercise price  for Non-Qualified Options.   The exercise  price is payable
     in cash, in  shares of Common Stock owned by a participant, with respect to
     Non-Qualified Options,  a promissory  note payable  to the  Company, or  by
     cashless  exercise  with  a  participant's broker,  as  determined  by  the
     Committee.  

              Stock options  granted under  the 1996  Plan are not  transferable
     except by will or  the laws of descent and distribution.   Unless otherwise
     provided  in   the  relevant   option  agreement,  options   will  only  be
     exercisable within  three months  of  any termination  of employment  other
     than termination for  "cause" or termination  due to  death or  disability.
     Unless otherwise  provided in the  relevant option agreement, options  will
     be exercisable by a participant or beneficiary, as the case may be,  within
     one year of a  termination of employment by reason of death  or disability.
     If  a  participant's employment  is  terminated  for  "cause,"  his or  her
     options will no  longer be exercisable after  the date of such  termination
     of employment unless the option agreement provides otherwise.

              The Committee  may provide,  at  the time  of grant  of  Incentive
     Stock Options and at  or after the time of grant of  Non-Qualified Options,
     that, if a participant  surrenders already owned shares of Common  Stock in
     full  or  partial   payment  of  an  option,  then,  concurrent  with  such
     surrender, the  participant,  subject  to  the availability  of  shares  of
     Common Stock  under the  1996 Plan,  will  be granted  a new  Non-Qualified
     Option  (a "Reload  Option") covering a  number of  shares of  Common Stock

                                          68
<PAGE>






     equal to  the number  so surrendered.   A Reload Option  may be  granted in
     connection with the exercise  of an option that is itself a  Reload Option.
     Each  Reload Option  will have  the same  expiration date  as  the original
     option  and an  exercise  price  equal to  the  fair  market value  of  the
     Company's  shares of  Common  Stock on  the  date of  grant  of the  Reload
     Option.  A  Reload Option  is exercisable immediately  or at  such time  or
     times as the  Committee determines and will be  subject to such other terms
     and conditions as the Committee may prescribe.

              Restricted  Shares.  The Committee may  award restricted shares to
     a participant.   Such  a grant  gives a  participant the  right to  receive
     shares of Common Stock subject to a  risk of forfeiture based upon  certain
     conditions.  The  forfeiture restrictions on the shares of Common Stock may
     be based upon performance standards,  length of service, or  other criteria
     as the  Committee may  determine.   Until all  restrictions are  satisfied,
     lapsed, or  waived, the Company  will maintain control  over the restricted
     shares but the participant will be able to vote  the shares of Common Stock
     and generally will be  entitled to dividends on the shares of Common Stock.
     Upon  termination of  employment, the  participant  generally forfeits  the
     right  to  the  shares  of  Common  Stock  to  the  extent  the  applicable
     performance   standards,   length   of  service   requirements,   or  other
     measurement criteria have not been met.

              Non-Employee Director  Options.   The 1996 Plan  provides for  the
     automatic grant  of a  Non-Qualified Option  to purchase  10,000 shares  of
     Common Stock to  each non-employee director on the first  date he or she is
     elected as  such  by the  Company's  shareholders.   However,  non-employee
     directors  who are  first  elected as  such  by the  Company's shareholders
     prior  to the  1996 annual  meeting are  not  entitled to  receive such  an
     option.   The option price is  the fair market  value of a  share of Common
     Stock on the date  of grant of such option.   All such options have a  five
     year term and are exercisable in full on the date of grant.

              If a  non-employee director's service with  the Company terminates
     by  reason of death, his or her option may be exercised for a period of one
     year  from the  date  of  death or  until  the  expiration of  the  option,
     whichever is  shorter.   If  a  non-employee  director's service  with  the
     Company terminates other than by reason of death, his  or her option may be
     exercised for a period of three months  from the date of such  termination,
     or  until the expiration  of the  stated term  of the option,  whichever is
     shorter.

              Duration of  the 1996 Plan;  Share Authorization.   The 1996  Plan
     will remain in  effect until  June 11, 2006,  unless terminated earlier  by
     the Company's Board of Directors.   Awards may be issued with respect to up
     to 3,500,000 shares of Common  Stock.  Such shares of Common Stock  have an
     aggregate market value of $21  million based on the initial public offering
     price of $6.00. 

              In  the event the purchase  price of an option is  paid, or tax or
     withholding payments relating  to an award  are satisfied,  in whole or  in
     part through  the  delivery of  already  owned shares  of  Common Stock,  a

                                          69
<PAGE>






     participant will be deemed to have received an award with respect to  those
     shares  of  Common Stock.    The Common  Stock  covered by  any unexercised
     portions  of  terminated options,  shares  of  Common Stock  forfeited  and
     shares of Common Stock subject to awards  that are otherwise surrendered by
     a participant without receiving any  payment or other benefit  with respect
     thereto may again be subject to new awards under the 1996 Plan.

              1996  Plan Administration.   The 1996 Plan is  administered by the
     Compensation Committee,  a committee  of the Company's  Board of Directors.
     Prior to consummation of  the Offering,  the  Committee  will be  comprised
     solely of non-employee directors who are not eligible to participate in the
     1996 Plan except with respect to certain automatic, non-discretionary stock
     option awards,  as described above.   The Committee will  determine the key
     employees  and  consultants  who  are  eligible  for  and  granted  awards,
     determine the  amount and  type of  awards, determine the  duration of  the
     option (which may  not exceed ten  years), establish  rules and  guidelines
     relating  to the  1996  Plan, establish,  modify,  and terminate  terms and
     conditions  of awards and  take such other action  as may  be necessary for
     the proper administration of the 1996 Plan.

              The members  of the  Committee are  appointed by  the  Board.   As
     directors, members of the  Committee may  be removed at  any time but  only
     for cause and only  by the affirmative vote of  the holders of 67%  or more
     of the outstanding shares of the  Company's capital stock entitled to  vote
     generally in the election of  directors (considered for this purpose as one
     class) cast at a meeting of the shareholders called for that purpose.

              Transferability; Repurchase Right.  Each  participant who receives
     an award under the 1996  Plan is prohibited from transferring  or otherwise
     disposing  of the  underlying shares of  Common Stock  until 180  days have
     elapsed following  such time as  the Company has  consummated the Offering.
     However, shares of  Common Stock may be used  to pay the exercise  price of
     options and to  pay withholding  and other taxes  as otherwise provided  in
     the 1996 Plan.

              Upon a  participant's termination  of employment, the  Company has
     the right to repurchase any  or all of the shares of Common Stock issued to
     the  participant with respect  to awards made under  the 1996 Plan, whether
     then held  by the  participant or  a transferee,  at fair  market value  as
     determined by the Committee.   The Company's right to repurchase  shares of
     Common Stock terminates once the Offering is consummated.

              Change in Control.  Upon the occurrence of a  change in control of
     the  Company,   all  options   become  immediately   exercisable  and   all
     restrictions on restricted shares lapse.  A change in control includes:

                      (1)  approval of  the Company's shareholders of a
              consolidation  or merger  of the  Company  with any  third
              party, unless  the Company  is the  entity surviving  such
              merger or consolidation;



                                          70
<PAGE>






                      (2)  approval of  the Company's shareholders of a
              transfer of all  or substantially all of the assets of the
              Company  to a  third party  or a  complete liquidation  or
              dissolution of the Company;

                      (3)  A third party (other than James F. Chen  and
              his affiliates),  directly or  indirectly, through  one or
              more  subsidiaries or  transactions or  acting in  concert
              with one  or more  persons or  entities: (a)  acquires any
              combination  of  beneficial  ownership  of  the  Company's
              voting  stock and  irrevocable  proxies representing  more
              than 20% of  the Company's voting stock; (b)  acquires the
              ability  to  control  in  any manner  the  election  of  a
              majority of the directors of the Company; or (c)  acquires
              the  ability   to  directly   or  indirectly  exercise   a
              controlling influence  over the management  or policies of
              the Company;

                      (4)  any election has occurred of persons  to the
              Company's Board  of Directors  that causes  a majority  of
              such Board  to consist of  persons other than (a)  persons
              who   were  members   of  the  Board   on  June  12,  1996
              ("Effective Date")  and/or (b) persons  who were nominated
              for election  as members of the  Board by the  Board (or a
              committee of the  Board) at a  time when  the majority  of
              the Board (or of such committee)  consisted of persons who
              were members of the Board on the Effective Date; or

                      (5)   A determination  is made by the  SEC or any
              similar  agency having regulatory control over the Company
              that  a change  in control,  as defined  in the securities
              laws or  regulations then applicable  to the Company,  has
              occurred.

              Termination and Amendment.   The Board may amend or  terminate the
     1996 Plan  and the Committee may  amend or alter the  terms of awards under
     the  1996 Plan but  no such action  shall affect or  in any  way impair the
     rights of a  participant under any  award previously  granted without  such
     participant's  consent.   No  amendment may  be  made, without  shareholder
     approval, that would require shareholder approval under  any applicable law
     or rule unless the  Board determines that compliance with such law  or rule
     is no longer desired. 

              Antidilution Provisions.   The  number of  shares of  Common Stock
     authorized to be  issued under  the 1996  Plan and  subject to  outstanding
     awards  (and the purchase  or exercise price  thereof) will  be adjusted to
     prevent  dilution  or  enlargement of  rights  in the  event  of  any stock
     dividend,  stock  split,   combination  or  exchange  of   shares,  merger,
     consolidation or other change in capitalization with  a similar substantive
     effect upon the 1996 Plan or the awards.

              Awards  Made.   As  of June  12, 1996,  the Committee  has granted
     Incentive and Non-Qualified  Options to purchase 1,389,860 shares of Common
     Stock under the  1996 Plan.   As of such  date, no restricted share  awards

              Certain Federal  Income  Tax Consequences.   The  following  is  a
     brief summary  of the principal  federal income tax  consequences of awards
     under the 1996 Plan based upon current federal income tax laws.  

              A  participant  is not  generally subject  to  federal  income tax
     either at the  time of grant  or at the  time of exercise  of an  Incentive
     Stock Option.   However,  upon exercise,  the difference  between the  fair
     market value of the shares  of Common Stock and  the exercise price may  be
     includable in the participant's alternative  minimum taxable income.   If a
     participant does not  dispose of shares  of Common  Stock acquired  through
     the  exercise of  an  Incentive Stock  Option within  one year  after their
     receipt and within  two years  after the date  of the  option's grant,  any
     gain or loss  upon the disposition will be  taxed as long-term capital gain
     or loss.  

              The Company will not receive any tax  deduction on the exercise of
     an Incentive Stock Option  or, if the holding requirements are met,  on the
     sale  of  the underlying  shares  of  Common  Stock.   If  a  disqualifying
     disposition occurs (i.e., one  of the holding requirements is not met), the
     participant will be treated as  receiving compensation subject to  ordinary
     income tax in  the year of the  disqualifying disposition, and the  Company
     will  be entitled  to  a deduction  for compensation  expense in  an amount
     equal to  the amount  the participant  includes in  income.   The tax  will
     generally  be imposed on  the difference between  the fair  market value of
     the shares of Common  Stock at the time of exercise and  the exercise price
     or, if less,  the gain the participant realized on  the sale of the shares.
     Any appreciation  in value  after the  time of  exercise will  be taxed  as
     long-term or short-term capital gain (depending on how long the shares  are
     held after exercise) and will not result in any deduction by the Company.
       
              There are no  federal income  tax consequences  to participant  at
     the time of grant of  a Non-Qualified Option.  Upon exercise of the option,
     the participant must  pay tax  on ordinary income  equal to the  difference
     between the exercise  price and  the fair  market value  of the  underlying
     shares on the  date of exercise.   The Company will receive  a commensurate
     tax  deduction at the  time of exercise.   Any appreciation  in value after
     the time  of exercise will be taxed  upon the disposition of  the shares as
     long-term or short-term capital gain (depending on how long  the shares are
     held after exercise), and  will not result in any deduction by the Company.
     Non-employee  director  options will  receive the  same federal  income tax
     treatment as other Non-Qualified Options.

              Except as described  below, a grant of restricted shares  does not
     constitute  a  taxable event  for  either  a  participant  or the  Company.
     However,  the participant will be subject to tax, at ordinary income rates,
     when  any restrictions on  ownership of the  shares of  Common Stock lapse.
     The  Company will  be entitled  to take  a commensurate  deduction  at that
     time.

              A  participant may elect to  recognize taxable ordinary  income at
     the time  restricted shares  are awarded  in an  amount equal  to the  fair
     market  value  of  the  shares  of  Common  Stock  at the  time  of  grant,

                                          73
<PAGE>






     determined  without regard  to  any forfeiture  restrictions.   If  such an
     election is made, the Company will be entitled to a deduction  at that time
     in the same  amount.   Future appreciation on  the shares  of Common  Stock
     will be taxed  when the shares are  sold as capital gain (depending  on how
     long  the shares  are held  after exercise),  and  will not  result in  any
     deduction by the  Company.  If, after  making such an election,  the shares
     of Common Stock  are forfeited, the participant  will be unable to  claim a
     deduction.

     Employment Agreement

              On  June  12,  1996,   the  Company  entered  into  an  employment
     agreement  with James F.  Chen at an  annual base salary of  $125,000.  The
     employment agreement has  a two year term  commencing on June 12,  1996 and
     is automatically renewed for additional  two year terms on  each successive
     June  12,  commencing  June 12,  1997.    However, either  party  may serve
     written notice of  termination prior to June  12, 1997 or prior to  June 12
     of each succeeding  year, as the case  may be, in which  case the agreement
     will terminate at  the end of the two year period that begins with the June
     12 following the date of such written notice.

              Under the employment  agreement, the Board (or  a Board committee)
     is obligated  to  review Mr.  Chen's  base  salary promptly  following  the
     completion of the Offering and thereafter at  least annually.  As a  result
     of such review, the  Board or committee may,  in its discretion,  increase,
     but  generally  may not  decrease,  Mr.  Chen's  base salary.    After  any
     adjustment following the  Offering, the Board or committee may not increase
     his base salary for any one year by an amount greater  than 50% of his then
     base salary.  It is  intended that the Board or committee  will consider in
     any  such  review   factors  relating  to  his  performance,   duties,  and
     responsibilities  and  endeavor to  maintain  his compensation  at  a level
     comparable to  that  of  similarly  situated executives  in  the  Company's
     industry.   The  employment agreement  also provides  that Mr.  Chen may be
     paid such  bonuses, if any,  as may  be awarded  from time to  time by  the
     Board or such  committee, in its discretion.   Such bonuses shall  be based
     on results  of operations,  special contributions  made by  him, seniority,
     competitive conditions in the  Company's industry,  and such other  factors
     as the Board or such committee considers relevant.  

              In the event that (i) Mr. Chen terminates his employment with  the
     Company  (other than  because of his  death) within  two years  following a
     change in  control  (as defined  in  the  employment agreement),  (ii)  the
     Company  terminates Mr.  Chen's  employment  for  any  reason  (other  than
     because of  death, disability, or just cause)  within two years following a
     change in  control,  (iii) Mr.  Chen  terminates  his employment  with  the
     Company  because  of  the  Company's  material  breach  of  the  employment
     agreement, (iv) Mr. Chen's base  salary is reduced unless such reduction is
     permitted  by the  employment  agreement, or  (v)  the Company's  principal
     executive  offices are  relocated to a  location outside Montgomery County,
     Maryland, or the Company requires Mr. Chen to  be based anywhere other than
     the Company's principal  executive offices, then  the Company  must make  a
     lump sum severance  payment to Mr. Chen.   The payment is equal to  the sum

                                          74
<PAGE>






     of (a) the aggregate  amount of  the future base  salary payments Mr.  Chen
     would have received if he continued  in the employ of the Company until  24
     months  (36 months  if  an event  described in  clauses  (i) or  (ii) above
     occurs) following the termination date  and (b) Mr. Chen's  projected bonus
     for the year  in which the termination  date occurs.  The  payment required
     by clause (a) is calculated at the  highest rate of base salary paid to Mr.
     Chen  at  any time  under  the  employment  agreement,  with such  payments
     discounted to present value at  a discount rate equal  to 1% above the  per
     annum one-year Treasury Bill  rate.  The bonus amount is  computed assuming
     that Mr.  Chen had remained in  the Company's employ until  the end of that
     year and  that all  performance goals  or other  performance measures  have
     been met at the then current level for the remainder of that year.  

              The Company may terminate Mr.  Chen's employment for "just  cause"
     at any  time by  giving him written  notice, in  which case the  Company is
     only obligated to  pay him his  base salary as  then in effect through  the
     termination  date.   If Mr.  Chen fails  to  perform his  duties under  the
     employment agreement on  account of a disability, the Company may terminate
     the agreement on a date  not less than 30 days thereafter unless he resumes
     full performance of  his duties within such  period.  Mr. Chen  is entitled
     to terminate his employment with  the Company on, or  at any date after,  a
     date on which he  is at least 65 years old.   The employment agreement also
     terminates in  the event of  Mr. Chen's death.   In either such  event, the
     Company  must pay  Mr. Chen  or his  legal  representative Mr.  Chen's base
     salary as then in effect that  has accrued to the last day of the  month in
     which the retirement date or the date of death occurs.

     Director Compensation

              To  date,  directors  have  received  no  compensation  for  their
     services  as directors.    As  of April  26,  1996,  the Company  began  to
     reimburse directors  for travel expenses incurred  in connection with their
     attendance at meetings of the Board of  Directors and its committees.   The
     new  non-employee directors  elected  at the  June  1996 annual  meeting of
     shareholders will receive  an option to  purchase 10,000  shares of  Common
     Stock  under the  1996 Plan  upon such  election.   See "  - 1996 Incentive
     Stock Plan."

     Compensation Committee Interlocks and Insider Participation

              During   the  year   ended  December   31,  1995,   the  Company's
     Compensation Committee was composed  of directors James F.  Chen, President
     and  Chief Executive  Officer of the  Company, and his  brother, Charles C.
     Chen, Secretary of the Company.

                                CERTAIN TRANSACTIONS

              The Company  was initially capitalized by  a $10,000 investment by
     its founder,  President and  Chief Executive Officer,  James F. Chen.   Mr.
     Chen has,  on three  separate occasions,  made loans  to the  Company.   On
     December 31, 1993, 1994, and  1995, in consideration for loans  of $39,705,


                                          75
<PAGE>






     $32,729,  and  $143,644,  respectively,  the  Company  issued  8%  interest
     bearing notes, due on demand, to Mr. Chen.

              On  May 15, 1995,  Scientek Corporation, through Hai  Hua Cheng, a
     director of  the  Company, and  C.C. Tsai,  invested $500,000  in V-ONE  in
     consideration  for ownership  of 15%  of  the Company's  outstanding Common
     Stock after giving effect to  this issuance.  As further  consideration for
     this  investment, the  Company issued 84,000  shares of  Common Stock  to a
     voting  trust (the  "Voting  Trust")  for the  benefit  of Mr.  Cheng,  the
     majority owner of Scientek Corporation.  Mr. Chen  serves as voting trustee
     for this trust under a Voting  Trust Agreement dated January 1, 1996.   The
     proceeds of this financing were used to meet general operating expenses.

              On  June  1, 1995,  the Company  borrowed  $330,000  from Scientek
     Corporation and issued a promissory note, bearing  no interest, due June 1,
     1996.  The note has been assigned to Hai Hua Cheng by Scientek Corporation.
     The terms of the note provide that, as  further consideration for the loan,
     the Company  would  issue  230,000  shares  of  Common  Stock  to  Scientek
     Corporation  immediately  after   repayment  of  the  loan.     As  further
     consideration for the  loan, the Company  issued 115,000  shares of  Common
     Stock  to the voting  trust for the benefit  of Mr.  Cheng described above.
     On May 17, 1996, Mr. Cheng executed  an agreement extending the term of the
     note to May 31, 1997.  On June  12, 1996, in consideration for Mr.  Cheng's
     agreement not to demand payment of  the note until May 31, 1997,  the Board
     of  Directors authorized  the  Company to  offer  Mr. Cheng  the  option to
     receive Common Stock  based on a $3.00  per share conversion price  in lieu
     of cash  in payment  of the note.   The Board  reserved and  authorized the
     issuance  of  110,000  shares  of  Common  Stock  for  this  purpose.    In
     connection with  this loan,  the Company  recognized  interest expenses  of
     $32,545 and $63,624 during the year ended  December 31, 1995 and the  three
     months ended March 31, 1996, respectively.

              On May  15, 1995, Mr.  Chen contributed 199,000  shares of  Common
     Stock to the  capital of the Company for  the Company's use in transferring
     the above-described  84,000 and 115,000 shares  to the Voting  Trust.  When
     the Company  issues the above-described  230,000 shares of  Common Stock to
     Mr. Cheng, Mr.  Chen will contribute 230,000 shares  of Common Stock to the
     capital of the Company.

              On May  15, 1995,  Mr.  Chen also  contributed 500,000  shares  of
     Common Stock owned by him to the  capital of the Company for the Company to
     transfer to  Jieh-Shan  Wang, Senior  Vice  President of  Engineering,  for
     services  rendered.   In addition,  on April  4, 1996 Mr.  Chen contributed
     575,951 shares  of Common Stock owned by him  to the capital of the Company
     for the Company to transfer to participants in the Non-Statutory Plan.

              Two  of  the  Company's  executive  officers, Jieh-Shan  Wang  and
     William C.  Wilson, have paid  for options granted  under the Non-Statutory
     Plan with promissory notes.   The  only one of  the two executive  officers
     who borrowed more  than $60,000 from the Company  is Jieh-Shan Wang, Senior
     Vice President  - Engineering.  Mr. Wang borrowed $124,750 from the Company
     and executed  a 6%  interest-bearing promissory  note, due  April 22, 2006,

                                          76
<PAGE>






     that is secured  by the shares  of Common Stock  issued on exercise  of the
     option by Mr. Wang (the "Pledged  Shares").  The terms of the note  provide
     for payments of principal  and interest to be  made annually, beginning  on
     April  22, 1997.   If, at  any time, the  fair market value  of the Pledged
     Shares securing the  note is less than  the amount due under  the note, Mr.
     Wang  will  remain liable  for the  balance  due.   If  Mr. Wang  sells the
     Pledged Shares at any  time prior to April  22, 2006, then the proceeds  of
     the  sale will be applied to the balance of the note before payment will be
     made  to Mr.  Wang.   See  "Management -  1996  Non-Statutory Stock  Option
     Plan."

              In June 1996, the Company borrowed $1.5 million from JMI  pursuant
     to the  issuances of  unsecured, 8%  interest-bearing, senior  subordinated
     notes in  the principal amount of $1.5 million  with detachable warrants to
     purchase  500,000  shares of  Common  Stock.    Of  the 500,000  detachable
     warrants, 400,000  are  exercisable at  $3.00  per  share and  100,000  are
     exercisable  at  $0.01  per  share.    The  notes  must  be  redeemed  upon
     consummation of the  Offering and the  warrants with  an exercise price  of
     $0.01 per share must be exercised by June 30, 1996.

                                PRINCIPAL SHAREHOLDERS

              The following  table sets forth certain  information regarding the
     beneficial ownership of the Company's Common Stock and Series A Stock as of
     June 12, 1996, and as adjusted to  reflect the conversion of all  shares of
     Series  A  Stock into shares of Common Stock on  completion of the Offering
     (assuming the  initial offering price is $5.25 or greater), the exercise of
     100,000  detachable warrants issued to JMI, and the sale  by the Company of
     the  shares offered hereby,  by (i) each person who is known by the Company
     to own beneficially more than 5% of the  outstanding Common Stock or Series
     A Stock, (ii) each  of  the Company's  directors,  and  (iii)  all  current
     directors and executive officers of the Company as a group.

                             DESCRIPTION OF CAPITAL STOCK

       The Company  is authorized  to issue  up to  50,000,000 shares of  Common
     Stock,  $0.001 par value, and 20,000,000 shares  of Preferred Stock, $0.001
     par value.

       The  following summary  of  certain provisions  of  the Common  Stock and
     Preferred Stock  does not  purport to be  complete and  is subject to,  and
     qualified in  its entirety  by, the  provisions of  the Company's  Restated
     Certificate  of Incorporation and  Restated Bylaws,  which are  included as
     exhibits to the Registration Statement of which this Prospectus is  a part,
     and by the provisions of applicable law.

     Common Stock

       As of  June  12, 1996,  there  were  12,473,308 shares  of  Common  Stock
     outstanding  that were  held of  record by  approximately 43  shareholders.
     There will be 17,440,638  shares of Common  Stock outstanding (assuming  no
     exercise of  the Underwriters'  over-allotment  option and  no exercise  of
     outstanding  options)  after  giving effect  to  the  sale  of newly-issued
     Common Stock offered to the public hereby.

       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  as long  as  any
     shares  of  the Company's  Series  A  Stock  are  issued  and  outstanding.
     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.  See  "Dividend Policy."
     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.   All outstanding  shares of Common  Stock
     are fully  paid and non-assessable,  and the shares  of Common Stock to  be
     issued  upon completion  of  this  Offering will  be  fully  paid and  non-
     assessable.

     Preferred Stock

       The  Board of  Directors  has the  authority  to issue  up  to 20,000,000
     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

                                          82
<PAGE>






     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

       The  Company's Board  of Directors  created a  series of  Preferred Stock
     designated as  "Series A Convertible  Preferred Stock" (herein referred  to
     as "Series  A Stock")  pursuant to  Board Resolution and  a Certificate  of
     Designation, both dated April 4, 1994.  As of the date of  this Prospectus,
     1,186,518 shares of Series  A Stock are outstanding and are held  of record
     by 12 shareholders.  There will be no shares  of Series A Stock outstanding
     after the Offering is consummated.

       The holders of Series A  Stock ("Series A Shareholders") do not  have any
     preemptive  rights to subscribe for any  securities of the Company.  Series
     A Shareholders are entitled  to vote on all matters submitted to  a vote of
     the shareholders of the Company.   Series A Shareholders also  are entitled
     to vote  as a class on matters  affecting the value of  the Series A Stock.
     All actions  requiring the approval  of Series A  Shareholders voting as  a
     class must be authorized by  a majority vote of  the holders thereof.   The
     Board of Directors  may declare dividends on the  Series A Stock payable at
     any time in cash, in  property, or in shares  of Series A Stock.  Series  A
     Shareholders are  entitled to share  ratably in dividends  with the holders
     of  any other  series  of the  Company's  preferred stock  now  existing or
     hereafter created,  but receive no  preference in dividends  declared.  The
     Company will not  pay dividends on  Common Stock as  long as any  shares of
     Series A Stock are issued and  outstanding.  In the event of any  voluntary
     or  involuntary liquidation, sale, or  winding up of  the Company, Series A
     Shareholders are  entitled to receive,  in preference to  holders of Common
     Stock,  an amount equal  to the  purchase price per  share of  the Series A
     Stock plus any accrued but unpaid dividends.   Any remaining proceeds shall
     be allocated between Common  and Series A Shareholders on a pro rata basis,
     treating the shares of Series A Stock on an as-converted basis.  

       Shares of  Series A Stock  may at  any time be  converted into  shares of
     Common Stock, on a  one-for-one basis, provided that such shares  of Series
     A Stock  have not  previously been  converted by  automatic conversion.   A
     mandatory conversion will occur in the event of an initial public  offering
     in which at least  $15 million is raised and  the offering price per  share
     is at least 1.75 times the  initial conversion price of $3.00 per share  of
     Series A Stock  ($5.25).   The Series A  Stock will  not, however,  convert
     automatically if the initial offering  price is less than $5.25 per  share.
     The conversion ratio will be adjusted so that shares of Series A Stock  are
     convertible  into shares  of  Common Stock  on  a greater  than one-for-one
     basis as follows.  If the Company effects an initial public offering  prior
     to March 31,  1997 at  a price less  than $5.25  per share, the  conversion
     ratio will be adjusted  by multiplying the subscription price of  $3.00 per
     share by  1.75  ("Conversion Factor")  and  dividing  such product  by  the
     midpoint of the offering price  range contained in the  final pre-effective
     amendment to  the registration statement  relating to  such initial  public
     offering.   If the Company's initial public  offering occurs (i) during the

                                          83
<PAGE>






     period from April 1, 1997 to March 31, 1998 at a  price less than $6.00 per
     share or (ii) after  March 31, 1998 at a  price less than $9.00  per share,
     the conversion ratio  is adjusted as  set forth in  the preceding  sentence
     except the Conversion Factor  becomes 2.00 in the event clause  (i) applies
     or 3.00  in the event  clause (ii) applies.   The failure to  automatically
     convert (i) may  result in shares  of Series A Stock  remaining outstanding
     after the Offering, and (ii) will result in further dilution to holders  of
     Common Stock as a  result of the adjustment of the  conversion ratio.  This
     will limit the ability of the Company  to pay dividends on the Common Stock
     and will further  limit the  rights of the  holders of  Common Stock.   See
     "Risk Factors - Conversion of Series A Stock."

     Anti-takeover Effects  of Provisions of  the Certificate of  Incorporation,
     Bylaws and Delaware Law

       The  following provisions  of the  Restated Certificate  of Incorporation
     and Restated  Bylaws could discourage  potential acquisition proposals  and
     could delay  or  prevent  a  change  in  control  of  the  Company.    Such
     provisions  also  may   have  the  effect  of  preventing  changes  in  the
     management of the Company.   See "Risk Factors - Effect of  Certain Charter
     Provisions;  Anti-takeover Effects of  Certificate of Incorporation, Bylaws
     and Delaware law."

       Directors.  The Company's  Restated Certificate of Incorporation provides
     that, upon  the closing of this Offering, the  Company's Board of Directors
     will be classified into three classes of directors.    

         Under the Restated Certificate of Incorporation and Restated  Bylaws, a
     director may be removed only  for cause and by the affirmative  vote of 67%
     of the outstanding  shares entitled to vote  an election of directors  at a
     special  meeting called  for  that purpose.    See "Management  - Executive
     Officers and Directors."

       Preferred Stock.   The  Restated Certificate of  Incorporation authorizes
     20,000,000 shares  of Preferred  Stock with  a par  value of  $0.001.   The
     Company is authorized to issue preferred stock from time to time in  one or
     more  series,  and  the  Board  of  Directors  is  authorized  to  fix  the
     designations, powers  preferences and relative participating,  optional and
     other  special rights,  qualifications,  limitations  or restrictions  with
     respect to such shares.   In the event of  a proposed merger, tender  offer
     or other attempt  to gain control of  the Company of which  management does
     not approve, it might be possible for  the Board of Directors to  authorize
     the  issuance of  a series of  preferred stock with  rights and preferences
     that could impede the completion of such a  transaction.  See "Risk Factors
     -  Anti-takeover  Effects  of  Certificate  of  Incorporation,  Bylaws  and
     Delaware Law." 
        
       Certain   Business   Combinations.      The   Restated   Certificate   of
     Incorporation  also requires the  affirmative vote of not  less than 75% of
     the outstanding shares of capital stock of the  Company entitled to vote to
     effect a  merger, consolidation or sale of the Company with any "Interested
     Person"  as defined  in  the Certificate  of  Incorporation.   The Restated

                                          84
<PAGE>






     Certificate  of  Incorporation  also  provides  that  the  holders  of  the
     Company's  voting securities  must receive consideration  no less  than the
     "Fair Price"  or  fair market  value  of the  share  in connection  with  a
     merger, consolidation or sale of the Company.

       Special  Meetings of Shareholders.   In addition,  the Company's Restated
     Bylaws do not permit shareholders of the Company to call a special  meeting
     of shareholders; only the Company's  Chief Executive Officer or  a majority
     of the  members of  the Company's  Board of  Directors may  call a  special
     meeting of shareholders.

       Amendment of Bylaws.   The Restated Certificate of Incorporation requires
     the  affirmative vote of  not less  than 75%  of the outstanding  shares of
     capital stock of the  Company entitled to vote at an election  of directors
     to amend the Company's bylaws.

       Inspection  of   Books  and  Records.     The  Restated   Certificate  of
     Incorporation authorizes  the Board  of Directors to  determine whether, to
     what extent  and  under what  conditions,  the accounts  and  books of  the
     Corporation (other  than the stock ledger)  shall be open to  inspection by
     shareholders.  

       Delaware  Anti-Takeover Statute.   The Company is subject  to Section 203
     of  the  Delaware  General  Corporation  Law,  which,  subject  to  certain
     exceptions, prohibits a Delaware  corporation from engaging in any business
     combination with any  interested shareholder for  a period  of three  years
     following the date that such shareholder became an  interested shareholder,
     unless: (1) prior  to such date, the board  of directors of the corporation
     approved either the business combination  or the transaction that  resulted
     in  the   shareholder  becoming   an  interested   shareholder;  (2)   upon
     consummation of the transaction  that resulted in the shareholder  becoming
     an interested shareholder,  the interested  shareholder owned at  least 85%
     of  the  voting  stock  of  the corporation  outstanding  at  the  time the
     transaction commenced, excluding for  purposes of determining the number of
     shares outstanding those  shares owned (i) by persons who are directors and
     also  officers  and   (ii)  by  employee  stock  plans  in  which  employee
     participants do  not have  the  right to  determine confidentially  whether
     shares held subject  to the plan will  be tendered in a tender  or exchange
     offer,  or (3) on  or subsequent to such  date the  business combination is
     approved by the  board of directors and authorized  at an annual or special
     meeting of shareholders,  and not by  written consent,  by the  affirmative
     vote of at least 66 2/3% of the outstanding voting stock  that is not owned
     by the interested shareholder.

       Section  203 defines  business combination  when used  in reference  to a
     corporation and  any interested shareholder  to include: (i)  any merger or
     consolidation of  the corporation with the  interested shareholder  or with
     any  other corporation  if the  merger or  consolidation is  caused by  the
     interested shareholder and,  as a result of the transaction, Section 203(a)
     does not  apply  to  the  surviving  corporation;  (ii)  any  sale,  lease,
     exchange, mortgage,  transfer, pledge  or other  disposition involving  the
     interested shareholder  of 10% or  more of the  assets of  the corporation;

                                          85
<PAGE>






     (iii) subject  to certain exceptions,  any transaction that  results in the
     issuance or transfer by the corporation of any  stock of the corporation to
     the interested shareholder; (iv) any transaction  involving the corporation
     that has the  effect of increasing the proportionate  share of the stock of
     any  class   or  series  of   the  corporation  owned   by  the  interested
     shareholder; or  (v)  any receipt  by  the  interested shareholder  of  the
     benefit  of any  loans, advances,  guarantees, pledges  or  other financial
     benefits  provided by or through the corporation.   In general, Section 203
     defines an  interested  shareholder as  any entity  or person  beneficially
     owns, or within three years did own, 15% or more of the  outstanding voting
     stock  of the  corporation  and any  entity or  person  affiliated with  or
     controlling or controlled by such entity or person. 

                           SHARES ELIGIBLE FOR FUTURE SALE 

       Upon  completion  of this  Offering,  the Company  will  have outstanding
     17,440,638  shares  of  Common  Stock  (assuming  the  Underwriters'  over-
     allotment  option is not  exercised).   The 3,400,000  shares sold  in this
     Offering will be freely  tradeable without  restriction or registration  by
     persons  other  than  "affiliates"  of  the  Company,  as  defined  in  the
     Securities Act, who  would be  required to sell  under Rule  144 under  the
     Securities Act.   The 14,040,638  shares of Common  Stock held by  existing
     shareholders upon completion  of this  Offering, without  giving effect  to
     shares of  Common  Stock  that  are  subject  to  the  Underwriters'  over-
     allotment option, will be "restricted  securities" as that term  is defined
     in  Rule 144, and may be sold in the public market only if registered or if
     they qualify for an exemption from registration under Rules  144, 144(k) or
     701, which rules  are summarized below.   The foregoing numbers  assume the
     issuance of 280,812 shares to  RSA and MIT, the conversion of  the Series A
     Stock  on a  one-for-one basis (assuming  an initial  offering price  of at
     least $5.25 per share), and the exercise of 100,000 warrants at $0.01  upon
     consummation of the Offering.   See "Risk Factors - Conversion of  Series A
     Stock."  "Business - License  Agreements," "Description of Capital  Stock -
     Series A  Convertible Preferred Stock,"  and "Certain Transactions."   As a
     result of the  contractual provisions described below and the provisions of
     Rules 144, 144(k) and  701, additional shares will be available for sale in
     the public  market as follows:  (i) except for the  shares of Common  Stock
     offered  hereby  and  the  shares of  Common  Stock  subject  to the  over-
     allotment option, if exercised, no  additional shares will be  eligible for
     immediate sale  on the date  of this Prospectus,  and (ii) 1,698,983 shares
     will be  eligible for sale  upon expiration of  the lock-up  agreements 180
     days  after the  date of  this  Prospectus in  compliance  with Rules  144,
     144(k) or 701.

       In general,  under Rule  144 as currently  in effect,  beginning 90  days
     after the date  of this Prospectus, a  person (or persons whose  shares are
     aggregated) who  has  beneficially owned  shares  for  at least  two  years
     (including the holding period  of any prior owner except an  "affiliate" of
     the Company  as that term is  defined under Rule 144),  is entitled to sell
     in  "brokers' transactions"  or  to market  makers, within  any three-month
     period commencing 90 days after  the completion of this Offering,  a number
     of shares that  does not exceed the  greater of:  (i)  1% of the number  of

                                          86
<PAGE>






     shares  of  the  Company's Common  Stock  then  outstanding  (approximately
     174,406 shares immediately  after the Offering); or (ii) the average weekly
     trading  volume of  the  Company's Common  Stock  during the  four calendar
     weeks  preceding the required  filing of  a Form  144 with respect  to such
     sale.  Sales under Rule 144 are also  generally subject to the availability
     of current  public information  about the  Company.   Under Rule  144(k), a
     person  who is not deemed  to have been an affiliate  of the Company at any
     time during the  90 days preceding a  sale, and who has  beneficially owned
     the shares proposed  to be  sold for at  least three  years (including  the
     holding  period of  any prior  owner except  an affiliate), is  entitled to
     sell such  shares  without  complying  with  the  manner  of  sale,  public
     information, volume  limitation or notice  provisions of Rule  144.  Unless
     otherwise restricted,  "144(k) shares"  may therefore  be sold  immediately
     upon the completion of  this Offering.  The SEC is currently  considering a
     revision to Rule 144 that would reduce the two year holding  period in Rule
     144(d) to one year and  the three year holding period in Rule 144(k) to two
     years.  If  enacted, such modification will  have a material effect  on the
     timing of when certain shares of Common Stock become eligible for resale.

       Any employee,  officer or  director of or  consultant to the  Company who
     purchased  his or  her shares  pursuant to  a written compensatory  plan or
     contract may  be entitled  to rely  on the  resale provisions  of Rule  701
     promulgated  under the Securities Act.  Rule 701 permits affiliates to sell
     their  Rule 701 shares  under Rule 144  without complying  with the holding
     period  requirements of  Rule 144.   Rule  701 further  provides  that non-
     affiliates may sell such  shares in reliance on Rule 144 without  having to
     comply  with   the  public  information,   volume  limitation,  or   notice
     provisions of  Rule 144.   In both  cases, a holder  of Rule 701  shares is
     required to  wait until 90  days after the  date of this Prospectus  before
     selling  such shares.   Upon completion  of this  Offering, 501,358  of the
     575,951 shares of Common Stock issued upon  the exercise of options granted
     under the Non-Statutory Plan may be sold under Rule 701.

       The Company  has agreed not to  offer, issue, sell, agree  to sell, grant
     any option for the  sale of or otherwise dispose of directly  or indirectly
     any  shares  of   Common  Stock  or  any  securities  convertible  into  or
     exercisable or  exchangeable for  Common Stock  (except for  options to  be
     granted pursuant  to the  Company's 1996  Plan) for  a period  of 180  days
     after the date of  this Prospectus without the prior written consent of the
     Representatives.  This  agreement may be released without notice to persons
     purchasing shares  in the  Offering and  without notice  to  any market  on
     which the Common Stock is traded.

       The  Company's current shareholders, employees,  officers, directors, and
     holders of  options and warrants  to purchase  shares of Common  Stock have
     also agreed with  the Underwriters not to offer,  sell agree to sell, grant
     any option to purchase  or otherwise dispose of any shares of  Common Stock
     owned  by them for a period  of 180 days after the  date of this Prospectus
     without the prior  written consent of the Representatives, except for sales
     to the Underwriters  pursuant to the  Purchase Agreement.   This  agreement
     may be  released  without  notice  to  persons  purchasing  shares  in  the


                                          87
<PAGE>






     Offering  and without notice  to any  market on  which the Common  Stock is
     traded.

       Individuals  who  participated  in  the Note  Offering  and  subsequently
     exchanged  their Notes  for  shares of  Series  A Stock  ("Investors") were
     granted  two  demand   registration  rights  for  underwritten   and  shelf
     offerings of  Common Stock  by the  Company.   Investors, as  a group,  may
     exercise the  demand registration rights  at any time  for a period of  two
     years from  the closing date  of this Offering,  unless the holding  period
     under Rule 144 is shortened to a period of  less than two years.  Investors
     also were granted unlimited piggyback  registration rights with respect  to
     any offering of  Common Stock or Series A Stock by the Company.  Except for
     one Selling  Shareholder, all holders of  Series A Stock  have waived their
     piggyback registration rights with respect to the Offering.

       In  connection with the Company's  issuances of senior subordinated notes
     to  JMI, with  detachable  warrants to  purchase  500,000 shares  of Common
     Stock, the Company has granted  certain registration rights to  the holders
     of such  warrants.   See "Certain  Transactions."   At any  time after  six
     months  following  the  consummation  of  the  Offering,  holders  of  such
     warrants may exercise  one demand registration right to require the Company
     to register shares of the Company's Common Stock issuable upon  exercise of
     the warrants  in whole or  in part.  In  addition, the Company  has granted
     such warrant holders  unlimited piggyback registration rights  with respect
     to any  offering of securities  of the Company  and unlimited registrations
     on Form  S-3  with respect  to  at least  20% of  the  warrant shares  then
     outstanding.   The  exercise of  registration rights  and the  sale of  the
     shares so registered  could have an adverse effect  on the trading price of
     the Common Stock.  

       The Company  intends to  file a  registration statement  or  registration
     statements on Form S-8  under the Securities Act to register all  shares of
     Common  Stock  issuable  under  the 1995  Plan  and  the  1996  Plan.   The
     registration  statement  or statements  are  expected to  be  filed shortly
     after the  effective  date of  the  Registration  Statement of  which  this
     Prospectus is a  part and  will be effective  upon filing.   Shares  issued
     upon the exercise of  stock options after the effective date of the Form S-
     8  registration statement or statements will  be eligible for resale in the
     public  market  without  restriction,  subject  to   Rule  144  limitations
     applicable to affiliates and the lock-up agreements described above.  

       Prior to  this Offering, there has  been no trading market  for shares of
     Common  Stock, and no prediction can be made as to the effect, if any, that
     market sales of shares or the availability of shares for sale will have  on
     the  market price  of  the  Common  Stock  prevailing from  time  to  time.
     Nevertheless, sales  of a substantial number  of shares of  Common Stock in
     the public market  could adversely affect  the market price  of the  Common
     Stock and  could  impair the  Company's  future  ability to  raise  capital
     through an offering of its equity securities.

                                       UNDERWRITING

              The Company has entered into a Purchase Agreement (the "Purchase
     Agreement") with the underwriters listed in the table below (the
     "Underwriters"), for whom Piper Jaffray Inc. and Volpe, Welty & Company
     are acting as representatives (the "Representatives"). Subject to the
     terms and conditions set forth in the Purchase Agreement, the Company has
     agreed to sell to the Underwriters, and each of the Underwriters has
     severally agreed to purchase, the following number of shares of Common
     Stock set forth opposite each Underwriter's name in the table below:

       Name                                      Number of Shares
       ----                                      ----------------
       Piper Jaffray Inc.  . . . . . . . . .     
       Volpe, Welty & Company  . . . . . . .

               Total   . . . . . . . . . . .           3,400,000

              Subject to the terms and conditions of the Purchase Agreement,
     the Underwriters have agreed to purchase all of the Common Stock being
     sold pursuant to the Purchase Agreement, if any is purchased (excluding
     shares covered by the over-allotment option granted therein). In the event
     of a default by any Underwriter, the Purchase Agreement provides that in
     certain circumstances purchase commitments of the nondefaulting
     Underwriters may be increased or the Purchase Agreement may be terminated.

              The Representatives have advised the Company that the
     Underwriters propose to offer Common Stock directly to the public
     initially at the public offering price set forth on the cover page of this
     Prospectus and to certain dealers at such price less a concession of not
     more than $      per share. Additionally, the Underwriters may allow, and
     such dealers may reallow a concession not in excess of $      per share
     to certain other dealers. After the public offering, the public offering
     price and other selling terms may be changed by the Underwriters.

              The Company and the Selling Shareholders have granted to the
     Underwriters an option, exercisable by the Representatives within 30 days
     after the date of the Purchase Agreement, to purchase up to an additional
     510,000 shares of Common Stock at the same price per share to be paid by
     the Underwriters for the other shares offered hereby. If the Underwriters
     purchase any of such additional shares pursuant to this option, each
     Underwriter will be committed to purchase such additional shares in
     approximately the same proportion as set forth in the table above. The
     Underwriters may exercise the option only for the purpose of covering
     over-allotments, if any, made in connection with the distribution of the
     Common Stock offered hereby.

              The Representatives have informed the Company that neither they,
     nor any other member of the National Association of Securities Dealers,
     Inc. (the "NASD") participating in the distribution of this offering, will
     make sales of the Common Stock offered hereby to accounts over which they
     exercise discretionary authority without the prior specific written
     approval of the customer.


                                       89<PAGE>



              The offering of the shares is made for delivery when, as and if
     accepted by the Underwriters and subject to prior sale and to withdrawal,
     cancellation or modification of the offering without notice. The
     Underwriters reserve the right to reject an order for the purchase of
     shares in whole or in part.

              The Company's current shareholders, employees, officers, 
     directors, and holders of options and warrants, who will beneficially own
     in the aggregate 14,040,638 shares of Common Stock after the Offering,
     have agreed that they will not sell, offer to sell, issue, distribute or
     otherwise dispose of any shares of Common Stock owned by them prior to the
     date of this Prospectus for a period of 180 days after the date of this
     Prospectus, without the prior written consent of the Representatives. See
     "Shares Eligible For Future Sale." The Company has agreed that it will
     not, without the Representatives' prior written consent, offer, sell or
     otherwise dispose of any shares of Common Stock, options or warrants to
     acquire shares of Common Stock or securities exchangeable for or
     convertible into shares of Common Stock during the 180-day period
     following the date of this Prospectus, except that the Company may issue
     shares upon the exercise of options granted prior to the date hereof, and
     may grant additional options under the 1996 Plan.

              Prior to this Offering, there has been no public market for the
     Common Stock. The initial public offering price for the Common Stock will
     be determined by negotiation among the Company and the Representatives.
     Among the factors to be considered in determining the initial public
     offering price will be prevailing market and economic conditions, the
     Company's revenue and earnings, estimates of the business potential and
     prospects of the Company, the present state of the Company's business
     operations, an assessment of the Company's management and the
     consideration of the above factors in relation to the market valuations of
     companies in related businesses. The estimated initial public offering
     price range set forth on the cover of this preliminary prospectus is
     subject to change as a result of market conditions and other factors. See
     "Risk Factors-No Prior Public Market; Market Volatility."

              The Company and the Selling Shareholders have agreed to indemnify
     the Underwriters and their controlling persons against certain
     liabilities, including liabilities under the Securities Act, and to
     contribute to payments the Underwriters may be required to make in respect
     thereof.

                                    LEGAL MATTERS

              The validity of the Common Stock offered hereby will be passed
     upon for the Company by Kirkpatrick & Lockhart LLP. Certain legal matters
     in connection with the Offering will be passed upon for the Underwriters
     by Goodwin, Procter & Hoar LLP.

                          REPORT OF INDEPENDENT ACCOUNTANTS
                                      _________


     To the Board of Directors of
              Virtual Open Network Environment Corporation

              We have audited the accompanying balance sheets of Virtual Open
     Network Environment Corporation (the Company) as of December 31, 1994 and
     1995, and March 31, 1996, and the related statements of operations,
     stockholders' equity (deficit) and cash flows for the period from February
     16, 1993 (date of inception) to December 31, 1993, and for each of the two
     years in the period ended December 31, 1995, and the three month period
     ended March 31, 1996.  These financial statements are the responsibility
     of the Company's management.  Our responsibility is to express an opinion
     on these financial statements based on our audits.

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

              In our opinion, the financial statements referred to above
     present fairly, in all material respects, the financial position of the
     Company as of December 31, 1994 and 1995, and March 31, 1996, and the
     results of its operations and its cash flows for the period from February
     16, 1993 (date of inception) to December 31, 1993, and for each of the two
     years in the period ended December 31, 1995, and the three month period
     ended March 31, 1996, in conformity with generally accepted accounting
     principles.

                    VIRTUAL OPEN NETWORK ENVIRONMENT CORPORATION
                     NOTES TO FINANCIAL STATEMENTS - (Continued)
         (Information for the three months ended March 31, 1995 is unaudited)


     1.  Nature of Business:
         ------------------

           V-ONE develops, markets, and licenses a comprehensive suite of
         network security products that enable businesses to conduct secured
         electronic transactions and information exchange using private
         enterprise networks and public networks such as the Internet.  

           The Company was originally incorporated in the State of Maryland on
         February 16, 1993.  The Board of Directors authorized and the
         stockholders approved a ten-for-one stock split of the Company's
         common stock as of November 11, 1995.  Effective February 7, 1996, the
         Company merged with a pre-existing corporation formed in Delaware. 
         The Delaware corporation is the surviving corporation.

           In connection with the reincorporation, the Company increased the
         number of authorized shares of common stock from 20 million to 50
         million and authorized 20 million shares of preferred stock.  All
         references to common and preferred stock have been restated to give
         effect to this transaction.

     2.  Significant Accounting Policies:
         -------------------------------

         Interim Financial Statements and Reporting Period:
         -------------------------------------------------

           The financial statements for the three months ended March 31, 1995
         and related footnote information are unaudited and have been prepared
         on a basis substantially consistent with the audited financial
         statements, and in the opinion of management, include all adjustments
         (consisting of only normal recurring adjustments) necessary for a fair
         presentation of the results of the interim period.  The results of the
         three months ended March 31, 1996, are not necessarily indicative of
         the results for the entire year.

         Revenue Recognition:
         -------------------

           The Company's revenue recognition policy is in conformance with the
         American Institute of Certified Public Accountants' Statement of
         Position, 91-1 "Software Revenue Recognition."  Revenue is generally
         recognized from the license of software upon shipment, net of
         allowances, provided that no significant vendor obligations remain. 
         Allowances for estimated future returns, credits, and doubtful
         accounts are netted against accounts receivable.  Service and training
         revenue is recognized as the services are performed. 







                                                                      F-10

                     NOTES TO FINANCIAL STATEMENTS - (Continued)
         (Information for the three months ended March 31, 1995 is unaudited)


     2.  Significant Accounting Policies:
         -------------------------------

         Revenue Recognition, continued:
         -------------------

         Maintenance and support revenue is recognized ratably over the
         contract term, typically one year.  Payments received in advance of
         revenue recognition are included in deferred income.

           In some instances, the Company recognizes revenues from the sale of
         systems using the percentage of completion method as the work is
         performed, measured primarily by the ratio of labor hours incurred to
         total estimated labor hours for each specific contract.  When the
         total estimated cost of a contract is expected to exceed the contract
         price, the total estimated loss is charged to expense in the period
         when the information becomes known.

         Research and Development and Software Development Costs:
         -------------------------------------------------------

           Software development costs are included in research and development
         and are expensed as incurred.  Statement of Financial Accounting
         Standards ("SFAS") No. 86, "Accounting for the Cost of Computer
         Software to be Sold, Leased or Otherwise Marketed" requires the
         capitalization of certain software development costs once
         technological feasibility is established, which the Company generally
         defines as completion of a working model.  Capitalization ceases when
         the products are available for general release to customers, at which
         time amortization of the capitalized costs begins on a straight-line
         basis over the estimated product life, or on the ratio of current
         revenues to total projected product revenues, whichever is greater. 
         To date, the period between achieving technological feasibility and
         the general availability of such software has been short, and software
         development costs qualifying for capitalization have been
         insignificant.  Accordingly, the Company has not capitalized any
         software development costs.

         Cash and Cash Equivalents:
         -------------------------

           The Company considers all highly liquid investments with original
         maturities of three months or less to be cash equivalents.  Cash and
         cash equivalents include time deposits with commercial banks used for
         temporary cash management purposes.

         Inventories:
         -----------

           Inventories are valued at the lower of cost or market and consist
         primarily of computer equipment for sale on orders received from
         customers, items held for stock, and training kits.  Cost is
         determined based on specific identification.

                                                                      F-11

         (Information for the three months ended March 31, 1995 is unaudited)



     2.  Significant Accounting Policies:
         --------------------------------

         Property and Equipment:
         ----------------------

           Computer and office equipment, furniture and fixtures are recorded
         at cost.  Depreciation and amortization of furniture and equipment is
         calculated using the straight-line method over a useful life of three
         to seven years.

           Repairs and maintenance costs are charged to expense as incurred. 
         Upon sale or retirement of property and equipment, the costs and
         related accumulated depreciation are eliminated from the accounts and
         any resulting gain or loss on such disposition is included in the
         determination of net income. 

         Income Taxes:
         ------------

           Deferred income tax assets and liabilities are recognized for the
         future tax consequences attributable to differences between the
         financial statement carrying amounts of existing assets and
         liabilities and their respective tax bases.  Deferred income tax
         assets and liabilities are measured by applying presently enacted
         statutory tax rates, that are applicable to the future years in which
         deferred income tax assets or liabilities are expected to be settled
         or realized, to the differences between the financial statement
         carrying amount and the tax bases of existing assets and liabilities. 
         The effect of a change in tax rates on deferred income tax assets and
         liabilities is recognized in net income in the period which the tax
         rate is enacted.  

           The Company provides a valuation allowance against net deferred
         income tax assets if, based upon the available evidence, it is more
         likely than not that some or all of the deferred income tax assets may
         not be realized.

         Computation of Net Loss Per Common Share:
         ----------------------------------------

           Common equivalent shares are included in the per share calculations
         where the effect of their inclusion would be dilutive.  Common
         equivalent shares consist of Series A Convertible Preferred Stock and
         the assumed exercise of outstanding stock options.  Pursuant to
         Securities and Exchange Commission Staff Accounting Bulletin (SAB) No.
         83, the common equivalent shares issued by the Company during the
         twelve-months preceding the initial filing date of the registration
         statement relating to the Company's initial public




                                                                      F-12

     2.  Significant Accounting Policies:
         -------------------------------

         Computation of Net Loss Per Common Share, continued:
         ----------------------------------------

         offering (July 15, 1996), using the treasury stock method and the
         assumed public offering price (of $6.00 per share), have been included
         in the calculation of net loss per common share for all periods
         presented.

           Fully diluted net loss per common share is the same as primary net
         loss per common share.

         Risks, Uncertainties and Concentrations:
         ---------------------------------------

           The Company invests its cash primarily in money market funds with an
         international commercial bank.  The Company had a balance in these
         funds of $0, $1,175,279 and $1,390,341 as of December 31, 1994 and
         1995 and March 31, 1996, respectively.  The Company has not
         experienced any losses to date on its invested cash.  The Company's
         cash balances exceed Federal insured amounts.

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

           The Company sells its product to a wide variety of customers in a
         variety of industries.  The Company performs ongoing credit
         evaluations of its customers but does not require collateral or other
         security to support customer accounts receivable. In management's
         opinion, the Company has provided sufficient provisions to prevent a
         significant impact of credit losses to the financial statements.

           In 1993 and 1994, two customers accounted for over 70% and 65% of
         total revenue respectively.  In 1995, three customers accounted for
         over 39% of total revenue.  

           Twenty percent of revenues generated in the three month period ended
         March 31, 1996 related to one customer.

     2.  Significant Accounting Policies:
         -------------------------------

         Risks, Uncertainties and Concentrations, continued:
         ---------------------------------------

           One customer accounted for 36% of total accounts receivable as of
         December 31, 1995.  Two customers accounted for 32% of total accounts
         receivable as of March 31, 1996.

         Fair value of financial instruments:
         -----------------------------------

           The carrying amounts of the Company's assets and liabilities
         approximate fair value due to either the short-term maturity of those
         financial instruments or their negotiated market terms.

         Stock-based Compensation:
         ------------------------

           In October 1995, the Financial Accounting Standards Board issued the
         Statement of Financial Accounting Standards No. 123 ("SFAS 123")
         Accounting for Stock-Based Compensation, which is effective for the
         Company's financial statements for fiscal years beginning after
         December 15, 1995.  SFAS 123 allows companies to either account for
         stock-based compensation under the new provisions of SFAS 123 or under
         the provisions of Accounting Principles Board Opinion No. 25 ("APB
         25"), Accounting for Stock Issued to Employees, but requires pro forma
         disclosure in the footnotes to the financial statements as if the
         measurement provisions of SFAS 123 had been adopted.  The Company has
         continued to account for its stock based compensation in accordance
         with the provisions of APB 25.

         Reclassifications:
         -----------------

           Certain reclassifications have been made to the prior years'
         financial statements to conform to the classifications used in the
         current period.

     3.  Inventory:
         ---------

           The Company has provided an allowance for potentially non-salable
         inventory in the amounts of $0, $50,000 and $50,000 as of December 31,
         1994 and 1995, and March 31, 1996, respectively.








                                                                      F-14

     4.  Notes Payable:
         -------------

           In both December 1995 and January 1996, the Company issued $1.25
         million in promissory notes to individual investors bearing interest
         at 7%.  As of March 31, 1996, $2.5 million was outstanding related to
         the promissory notes.  The principal and interest are due and payable
         on June 30, 1996.  In the event the Company enters into a private or
         public offering, or the notes become due and payable, the note holders
         may convert the principal and interest into the shares of the
         Company's capital stock.  In the event the Company conducts a private
         placement, the conversion price is equal to the price per share being
         offered in the placement.  In the event of an initial public offering,
         or on the maturity date of the notes, the price per common share is
         based on current fair value.

           In October 1995, the Company entered into a $50,000 loan agreement
         with an international financial institution.  The loan requires
         monthly payments of interest at a rate equal to the institutions prime
         lending rate for the first twelve months, thereafter the interest rate
         increases to 1.5% over prime (9.75% as of March 31, 1996).  The
         Company is required to repay the loan through 36 monthly payments
         commencing October 1996.  The loan is collateralized by the assets of
         the Company and is subordinate to notes payable to a shareholder (See
         Note 5).

           Maturities of notes payable as of March 31, 1996 are as follows:

             1996    $2,508,333
             1997        16,666
             1998        16,667

     5.  Notes Payable to Related Parties:
         --------------------------------

           On June 1, 1995, the Company issued a promissory note for $330,000
         to a foreign shareholder.  In lieu of cash payments for interest the
         Company agreed to issue 345,000 shares of the Company's common stock
         to the note holder. As of March 31, 1996, the Company had issued
         115,000 shares under this agreement, recognizing interest expense of
         $63,624 and $32,545 during 1996 and 1995, respectively.

           The Company's president, who is the majority shareholder, has
         advanced the Company operating funds three separate promissory notes
         which are updated on an annual basis.  The notes bear interest at 8%
         and are due on demand.  Total amounts outstanding under the notes were
         $19,293, $143,644 and $142,169 as of December 31, 1994 and 1995, and
         March 31, 1996, respectively.

     6.  Income taxes, continued:
         ------------

           In 1995 and 1996, respectively, the net change in the valuation
         allowance for deferred income tax assets was an increase of
         approximately $344,000 and $300,000 due principally to increases in
         the net operating loss.  A valuation allowance has been recognized due
         to the uncertainty of realizing the benefit of net operating
         carryforwards.  As of March 31, 1996, the Company had net operating
         loss carryforwards of approximately $1,785,000, for Federal and state
         income tax purposes available to offset future taxable income.  The
         net operating loss carryforwards begin expiring in 2008.


     7.  Stockholders' Equity:
         --------------------

         Stock Split:
         -----------

           On November 11, 1995, the Board of Directors authorized and the
         stockholders approved a ten-for-one stock split of the outstanding
         shares of the Company's common stock.  All references to common stock,
         options, and per share data have been restated to give effect to the
         stock split.

         1995 Non-Statutory Stock Option Plan:
         ------------------------------------

           During 1995, the Company adopted the 1995 Non-Statutory Stock Option
         Plan (SOP) to attract and retain key employees.  The SOP is
         administered by a committee, appointed by the Board of Directors,
         which determines the number of options granted to a qualified
         employee, the vesting period, and the exercise price provided it is
         not below market value on the date of the grant.  In most cases the
         options vest over a three year period and terminate in ten years from
         the date of grant.  The SOP will terminate during May 2005 unless
         terminated earlier in accordance with the provisions of the SOP.

     7.  Stockholders' Equity:
         --------------------

         1995 Non-Statutory Stock Option Plan, continued:
         ------------------------------------

           As of March 31, 1996, the Compensation committee was authorized by
         the Board of Directors to grant options for a total of 528,444 shares
         of common stock under the SOP.  As of December 31, 1995 and March 31,
         1996, respectively, 66,667 and 209,484 of the options were vested and
         exercisable.  As of March 31, 1996, the Company had no shares of
         common stock available for grant under the plan.

           The Company accounts for the fair value of its grants under this
         plan in accordance with APB Opinion 25.  Accordingly, no compensation
         cost has been recognized for its incentive stock option plan.  Had
         compensation cost been determined based on the fair value at the grant
         dates for awards under the plan consistent with the method of SFAS
         123, the Company's net income and earnings per share would have been
         reduced to the pro forma amounts indicated below:

           The fair value of each option is estimated on the date of grant
         using a type of Black-Scholes option-pricing model with the following
         weighted-average assumptions used for grants for the three month
         period ended March 31, 1996: dividend yield of 0%, expected volatility
         of 0%, risk-free interest rate of 5.35% and expected lives of 3 years.

         --------------------

         1995 Non-Statutory Stock Option Plan, continued:
         ------------------------------------

           As of March 31, 1996 and December 31, 1995, the proforma tax effects
         under SFAS 109 of this standard would include an increase to both the
         deferred tax asset and the valuation allowance of $500 and $26,400,
         respectively, and no impact to the statement of operations.

         Reserved for Issuance:
         ---------------------

           The Board of Directors has authorized 280,812 shares of the
         Company's common stock to be reserved for issuance in accordance with
         a license agreement whereby the licensor may waive its future rights
         to any license fees in exchange for 2% of the Company's outstanding
         common stock until the date of an initial public offering (See Note
         8).

         Series A Convertible Preferred Stock:
         ------------------------------------

           The holders of Series A Convertible Preferred Stock ("Preferred
         Stock") do not have any preemptive rights to subscribe for any
         securities of the Company.  Preferred Stockholders are entitled to
         vote on all matters submitted to a vote of the stockholders of the
         Company.  The holders of Preferred Stock also are entitled to vote, as
         a class, on matters affecting the value of the Preferred Stock.  All
         action requiring the approval of holders of shares of Preferred Stock
         voting as a class must be authorized by a majority vote of the holders
         thereof.  The Board of Directors may declare dividends on the
         Preferred Stock payable at any time in cash, in property, or in shares
         of Preferred Stock.  Preferred Stock holders are entitled to share
         ratably in dividends with the holders of any other series of the
         Company's preferred stock now existing or hereafter created, but
         receive no preference in dividends declared.  The Company will not pay
         dividends on Common Stock as long as any shares of Preferred Stock are
         issued and outstanding.  In the event of any voluntary or involuntary
         liquidation, sale, or winding up of the Company, the holders of
         Preferred Stock are entitled to receive, in preference to holders of
         Common Stock, an amount equal to the purchase price per share of the
         Preferred Stock plus any accrued but unpaid dividends.  Any remaining
         proceeds shall be allocated between Common and Preferred Shareholders
         on a pro rata basis, treating the shares of Preferred Stock on an as
         if converted basis.  Shares of Preferred Stock may at any time be
         converted into shares of Common Stock, provided that such shares of
         Preferred Stock have not previously been converted by a mandatory
         conversion which shall take place in the event of an initial public
         offering in which at least $15 million is raised and the offering
         price per share is at least 1.75 times the initial conversion price
         per share of the Preferred Stock of $3.00 per share.

                                                                      F-21

         License Agreements:
         ------------------

           In 1994 the Company entered into two licensing agreements whereby
         the Company obtained the right to modify and sell certain technology
         used in the Company's product line.  One of the agreements requires
         the Company to pay fees based on product and subscription sales for
         any product using the licensed technology.  The other agreement
         provides for payment of fees based upon gross revenues of the Company. 
         This latter agreement also gives the licensor the right to forfeit
         future licensing fees in exchange for 2% of the Company's outstanding
         voting stock (See Note 7).  The Company incurred expenses totaling $0,
         $110,860 and $67,690 relating to these agreements in 1994, 1995 and
         1996, respectively.

         Licensing rights:
         ----------------

           The Company has incorporated in its services, the data encryption
         and authentication technology developed by another company (the
         Licensor) under the licensing agreement previously described.  The
         Company has become aware of a third party dispute over the rights to
         the Licensor's technology.  The Company has received no notification 




                                                                      F-23

         with respect to this matter and management believes that the Company
         will not experience detrimental effects from the outcome of this
         dispute.  The financial statements do not contain any adjustments that
         may result from the resolution of this matter.

     9.  Financing:
         ---------

           The Company has incurred net losses of $35,684, $406,288, $1,032,311
         and $994,660, for the period February 16, 1993 to December 31, 1993,
         for the years ended December 31, 1994 and 1995, and for the three
         month period ended March 31, 1996.  Management has historically been
         successful in obtaining outside financing to meet obligations and
         funding working capital requirements as they come due.  Most recently,
         the Company closed on several transactions that provided additional
         cash flow.  These are summarized below.

           During April 1996, the Company converted $2,500,000 in promissory
         notes to Preferred Stock.  The Company also raised an additional
         $1,000,000 by issuing 333,333 shares of Preferred Stock at $3.00 per
         share (See Note 10).

           During June 1996, the Company borrowed $1.5 million and issued
         unsecured, 8% interest-bearing, senior subordinated notes due June 18,
         2000, with 500,000 detachable warrants to purchase Common Stock.

           During June 1996, the Company signed a software license contract
         with a customer for $2 million, with payment terms of $500,000 to be
         received by June 30, 1996 and the remaining $1.5 million to be paid
         over the remaining two year contract period.

           During April 1996, the Board of Directors authorized the President
         to proceed with plans for the initial public offering of the Company's
         common stock.  In the event the Company does not successfully complete
         its initial public offering, the Company intends to pursue other
         financing alternatives that may be available to the Company and, if
         required, reduce its operating expenses.

     10. Subsequent Events:
         ---------------

           On April 15, 1996, the Company repaid the full amount of the
         promissory notes outstanding, including accrued interest, to seven of
         the investors who participated in the December 1995 and January 1996
         note offering, by issuing to those investors shares of the Company's
         Preferred Stock, at a price of $3.00 per share.  The Company paid cash
         to each of these investors in an amount equal to the value of any
         fractional shares of Preferred Stock that would otherwise have been
         transferred to such investors.  In addition, the Company permitted the
         seven investors to purchase an additional 333,333 shares of Preferred
         Stock at a price of $3.00 per share.  Of the remaining seven
         investors, two transferred their notes to one of the other remaining
         investors.  The remaining five investors exchanged their notes,
         including the transferred notes, for shares of the Company's Preferred
         Stock on May 24, 1996, also at a price of $3.00 per share.  A total of
         1,186,518 shares of Preferred Stock were issued as of May 24, 1996.

           Shares of Preferred Stock may at any time be converted into shares
         of Common Stock, on a one-for-one basis, provided that such shares of
         Preferred Stock have not previously been converted by automatic
         conversion.  A mandatory conversion will occur in the event of an
         initial public offering in which at least $15 million is raised and
         the offering price per share is at least 1.75 times the initial
         conversion price of $3.00 per share of Preferred Stock ($5.25).  The
         Preferred Stock will not, however, convert automatically if the
         initial offering price is less than $5.25 per share.  The conversion
         ratio will be adjusted so that shares of Preferred Stock are
         convertible into shares of Common Stock on greater than one-for-one
         basis as follows.  If the Company effects an initial public offering
         prior to March 31, 1997 at a price less than $5.25 per share, the
         conversion ratio will be adjusted by multiplying the subscription
         price of $3.00 per share by 1.75 ("Conversion Factor") and dividing
         such product by the midpoint of the offering price range contained in
         the final pre-effective amendment to the registration statement
         relating to such initial public offering.  If the Company's initial
         public offering occurs (i) during the period from April 1, 1997 to
         March 31, 1998 at a price less than $6.00 per share or (ii) after
         March 31, 1998 at a price less than $9.00 per share, the conversion
         ratio is adjusted as set forth in the preceding sentence except the
         Conversion Factor becomes 2.00 in the event clause (i) applies or 3.00
         in the event clause (ii) applies.

     10. Subsequent Events, continued:
         -----------------

           On June 12, 1996, in consideration for the foreign shareholder's
         agreement not to demand payment of the $330,000 note until May 31,
         1997, the Board of Directors authorized the Company to offer the
         foreign shareholder the option to receive common stock at $3.00 per
         share, in lieu of cash in payment of the note.  The Board reserved and
         authorized the issuance of 110,000 shares of common stock for this
         purpose.  On May 17, 1996, the foreign shareholder executed an
         agreement extending the term of the note to May 31, 1997.

           During April 1996, the Company adopted the 1996 Non-Statutory Stock
         Option Plan to attract and retain executive employees.  The plan is
         administered by a committee, appointed by the Board of Directors.  The
         option price will be the fair market value of the stock on the date of
         grant.  The options are not transferable, subject to various
         restrictions outlined in the agreement and must be exercised by
         December 31, 1996.  As of April 2, 1996, 575,951 options were granted
         under the plan.  No additional options are available for grant under
         the plan.  The options were exercised on April 22, 1996 at $.50 a
         share.

           During June 1996, the Company adopted the 1996 Incentive Stock
         Option Plan (the 1996 Plan), under which both options and restricted
         share awards may be made to the Company's key employees.  Both
         incentive stock options and options that are not qualified under
         Section 422 of the Internal Revenue Code of 1986, as amended ("Non-
         Qualified Options") are available under this plan.  The options are
         not transferable and are subject to various restrictions outlined in
         the agreement.  The 1996 Plan is administered by the Compensation
         Committee of the Board of Directors, which determines the number of
         options granted to a qualified employee, the vesting period, and the
         exercise price provided that it is not below market value.  The 1996
         Plan will terminate during June 2006 unless terminated earlier by the
         Board of Directors.

           During June 1996, the Compensation Committee was authorized by the
         Board of Directors to grant options for a total of 3,500,000 shares of
         common stock under the 1996 Plan.  To date, the committee has granted
         a total of 1,103,868 Non-Qualified Options and 285,992 incentive stock
         options, of which 466,674 and 85,792, respectively, were vested and
         exercisable.  Subsequent to the initial grants, the Company had
         2,110,140 shares of common stock available for grant under the 1996
         Plan.

           The 1996 Plan also provides for the automatic grant of a non-
         qualified option to purchase 10,000 shares of common stock to each
         non-employee director.  All options have a five year term and are
         exercisable on the date of grant.  As of June 1996, none of the
         Company's directors were eligible to participate in the 1996 Plan.



                                                                      F-26

     Item 14.  Indemnification of Directors and Officers

              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 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 by reason of the fact that such person 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


                                        II-1
<PAGE>






     of the provisions of 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
                      interests 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.

              Section 145 of the Delaware General Corporation Law provides that
     a corporation has the power to indemnify a director, officer, employee or
     agent of the corporation and certain other persons serving at the request
     of the corporation in related capacities against amounts paid and expenses
     incurred in connection with an action or proceeding to which he is or is
     threatened to be made a party by reason of such position, if such person
     shall have acted in good faith and in a manner he reasonably believed to
     be in or not opposed to the best interests of the corporation, and, in
     any criminal proceeding, if such person had no reasonable cause to believe
     his conduct was unlawful; provided that, in the case of actions brought by
     or in the right of the corporation, no indemnification shall be made with
     respect to any matter as to which such person shall have been adjudged to
     be liable to the corporation unless and only to the extent that the
     adjudicating court determines that such indemnification is proper under
     the circumstances.

              Pursuant to the provisions of the Common Stock Purchase Agreement
     (the "Underwriting Agreement"), the underwriters are obligated, under
     certain circumstances to indemnify directors and officers for the Company
     against certain liability, including liabilities under the Securities Act. 
     Reference is made to the form of Underwriting Agreement filed as Exhibit 1
     hereto.

     Item 15.  Recent Sales of Unregistered Securities.

              During the past three years, the Company has issued unregistered
     securities to persons as described below.  No underwriters or underwriting
     discounts or commissions were paid in connection with such issuances. 
     There were no public offerings in such transactions, and the Company
     believes that each transaction, unless otherwise noted, was exempt from
     registration requirements of the Securities Act of 1933, as amended (the
     "Securities Act"), by reason of Section 4(2) thereof, based on the private
     nature of the transactions and the financial sophistication of the
     purchasers, all of whom had access to complete information concerning the

                                        II-2

     Company and acquired the securities for investment and not with a view to
     the distribution thereof.  All share numbers indicated below have been
     retroactively adjusted to reflect the 10-for-1 stock split effective
     November 13, 1995.

              On February 21, 1994, the Company issued 8,500,000 shares to
     James F. Chen in consideration for a payment of $10,000.  On February 21,
     1994, the Company also issued: (i) 150,000 shares of Common Stock to
     Maxine Loh in consideration for a payment of $25,000; (ii) 450,000 shares
     of Common Stock to Ed Lee, Teresa Lee, David Luk and Lousia Lee in

     Stock to Charles C. Chen in consideration for a payment of $49,500; (iv)

     Rosenthal in consideration for a payment of $25,000; and (vi) 150,000

     $25,000.

     Common Stock to the capital of the Company and the Company issued 500,000
     shares of Common Stock to Jieh-Shan Wang in consideration for services
     rendered.

              On June 1, 1995, James F. Chen contributed 199,000 shares of
     Common Stock to the capital of the Company.  On that date, the Company
     issued 1,764,710 shares of Common Stock to Mr. H.H. Cheng in consideration
     for a payment of $500,000 which was made to the Company in December 1994. 
     To provide protection against dilution to Mr. Cheng's $500,000 investment,
     the Company issued 84,000 shares of Common Stock to Mr. James F. Chen as
     trustee of a voting trust for Mr. Cheng on June 1, 1995.  Also on June 1,
     1996, the Company issued an additional 115,000 shares of Common Stock to
     the voting trust established for Mr. Chen in consideration for providing a
     loan of $300,000.

              On December 12, 1995, the Company issued: (i) 61,930 shares of

                                        II-3

              Between May, 1995 and June 12, 1996, the Company granted options
     to purchase 320,000 shares of Common Stock at $0.283 and 206,444 shares of
     Common Stock at $1.67 per share under the Company's 1995 Non-Statutory
     Stock Option Plan.  On June 12, 1996, the Company granted options to
     purchase 885,604 shares of Common Stock $2.50 per share and options to
     purchase 504,256 shares of Common Stock at $3.00 per share under the
     Company's 1996 Incentive Stock Plan.  The Company believes that the option
     grants described in this paragraph are exempt from the registration
     requirements of the Securities Act by reason of Rule 701 promulgated
     thereunder because the options were granted pursuant to written
     compensatory benefit plans of the Company, copies of which were provided
     to each participant, and the aggregate offering price did not exceed the
     limit prescribed by Rule 701 in connection with any such grant.

              In April, 1996, the Company issued options to purchase 575,951
     shares of Common Stock subject to restrictions on transferability
     ("Restricted Stock"), at $0.50 per share, under the Company's 1996 Non-
     Statutory Stock Option Plan.  As of June 12, 1996, all options granted
     under the Plan had been exercised and a total of 575,951 shares of
     Restricted Stock had been issued.  The Company also believes that the
     transactions described in this paragraph are exempt from registration
     under the Securities Act by reason of Rule 701 as the options were granted
     pursuant to a written compensatory benefit plan of the Company, a copy of
     the plan was provided to each participant, and the aggregate offering
     price did not exceed the limit prescribed by Rule 701.  

              In December, 1995 and January, 1996, the Company borrowed $2.5
     million through the sale of 7% interest bearing, unsecured promissory
     notes due June 30, 1996 to fourteen investors ("Note Offering").  The
     Company issued: (i) a note dated December 19, 1995 in the amount of
     $200,000 to the Trustee under the Shapiro Family Trust; (ii) a note dated
     December 18, 1995 in the amount of $25,000 to Burnett H. Moody; (iii) a
     note dated December 15, 1995 in the amount of $25,000 to Norman D. Fine;
     (iv) a note dated December 15, 1995 in the amount of $500,000 to Lewis M.
     Schott; (v) a note dated December 22, 1995 in the amount of $175,000 to
     Bryan T. Vanas; (vi) a note dated December 22, 1995 in the amount of
     $100,000 to Joseph Lupo and Rosa Lupo; (vii) a note dated December 22,
     1995 in the amount of $225,000 to Lee DeVisser and Linda DeVisser,
     Trustees of the DeVisser Trust dated January 4, 1993; (viii) a note dated
     January 15, 1996 in the amount of $166,500 to Edgehill Capital Management
     LP; (ix) a note dated January 15, 1996 in the amount of $60,000 to J.
     Francis Lavelle; (x) a note dated January 15, 1996 in the amount of
     $547,000 to Steven A. Cohen; (xi) a note dated January 15, 1996 in the
     amount of $60,000 to John P. Holmes III; (xii) a note dated January 15,
     1996 in the amount of $166,500 to Golden Eagle Partners; (xiii) a note
     dated January 15, 1996 in the amount of $50,000 to John J. Egan IV; and
     (xiv) a note dated January 15, 1996, in the amount of $200,000 to Kenneth
     Lissak. 

                      On April 15, 1996, the Company exchanged the full amount
     of notes (including accrued interest) issued to seven investors for shares
     of the Company's Series A Convertible Preferred Stock ("Series A Stock")

                                        II-4
<PAGE>






     at $3.00 per share and paid cash to each of the seven investors in an
     amount equal to any fractional shares of Series A Stock.  The Company
     issued: (i) 68,175 shares of Series A Stock to the Trustee of the Shapiro
     Family Trust; (ii) 8,523 shares of Series A Stock to Burnett H. Moody;
     (iii) 8,528 shares of Series A Stock to Norman D. Fine; (iv) 170,566
     shares of Series A Stock to Lewis M. Schott; (v) 59,619 shares of Series A
     Stock to Bryan T. Vanas, (vi) 34,068 shares of Series A Stock to Joseph
     Lupo and Rosa Lupo and (vii) 76,654 shares of Series A Stock to Lee
     DeVisser and Linda DeVisser Trustees of the Lee DeVisser Trust dated
     January 4, 1993.

              On April 15, 1996 the Company offered certain of the investors

     $3.00 per share in proportion to each investor's pro-rata interest in the
     Note Offering.  The Company issued (i) 41,667 shares of Series A Stock to
     Stanley Shapiro in consideration for a payment of $125,001; (ii) 6,666

              Two of the remaining seven noteholders transferred their notes to
     another noteholder.  On May 24, 1996, the Company exchanged the full
     amount of the remaining notes (including accrued interest) for Shares of
     Series A Stock at $3.00 per share and paid cash in an amount equal to any
     fractional shares.  The Company issued: (i) 17,082 shares of Series A

              On May 23, 1996 RSA Data Security, Inc. ("RSA") exercised an
     option granted under the Company's license agreement with RSA, to convert
     its right to receive future royalties into 2% of the Company's issued and
     outstanding voting securities, after giving effect to the issuance to RSA,
     through the date of the public offering.  Pursuant to a separate agreement
     between RSA and Massachusetts Institute of Technology ("MIT"), MIT is
     entitled to receive 7.2% of any royalties that RSA receives.  As a result,
     the Company will issue to MIT, 7.2% of the 2% of shares to which RSA was
     entitled under the license agreement.  At the time of the Offering, RSA
     and MIT will be entitled to receive 260,594 and 20,218 shares of Common
     Stock, respectively,

              In June, 1996, the Company issued 16,667 shares of Common Stock
     to John J. Egan IV in consideration for consulting services rendered to the
     Company.

        *To be filed by amendment

     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 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 or any material change to such information
              in the registration statement.

                      (2)  That, for the purpose of determining any liability
              under the Securities Act of 1933, each post-effective amendment

                                        II-8
<PAGE>






              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 a post-
              effective amendment any of the securities being registered which
              remain unsold at the termination of the offering.

              (b)     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.  

              (c)   The undersigned registrant hereby undertakes that:

                      (1)  For purposes of determining any liability under the
              Securities Act of 1933, the information omitted from the form of
              prospectus filed as part of this registration statement in
              reliance upon Rule 430A and contained in the form of prospectus
              filed by the registrant pursuant to Rule 424(b)(1) or (4) or
              497(h) under the Securities Act shall be deemed to be part of
              this registration statement as of the time it was declared
              effective.

                      (2)  For the purpose of determining any liability under
              the Securities Act of 1933, each post-effective amendment that
              contains a form of prospectus 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.

              1.      Registration Statement.  A registration statement on Form
     S-1 (File No. 33-____) with respect to the Securities, including a
     preliminary form of prospectus, has been prepared by the Company in
     conformity with the requirements of the Securities Act of 1933, as amended
     (the "Act"), and the rules and regulations ("Rules and Regulations") of
     the Securities and Exchange Commission (the "Commission") thereunder and
     has been filed with the Commission; one or more amendments to such
     registration statement have also been so prepared and have been, or will
     be, so filed.  Copies of such registration statement and amendments and
     each related preliminary prospectus have been delivered to you.

              If the Company has elected not to rely upon Rule 430A of the
     Rules and Regulations, the Company has prepared and will promptly file an
     amendment to the registration statement and an amended prospectus.  If the
     Company has elected to rely upon Rule 430A of the Rules and Regulations,
     it will prepare and file a prospectus pursuant to Rule 424(b) that
     discloses the information previously omitted from the prospectus in
     reliance upon Rule 430A.  Such registration statement as amended at the
     time it is or was declared effective by the Commission, and, in the event
     of any amendment thereto after the effective date and prior to the First
     Closing Date (as hereinafter defined), such registration statement as so
     amended (but only from and after the effectiveness of such amendment),
     including the information deemed to be part of the registration statement
     at the time of effectiveness pursuant to Rule 430A(b), if applicable, is
     hereinafter called the "Registration Statement."  The prospectus included
     in the Registration Statement at the time it is or was declared effective
     by the Commission is hereinafter called the "Prospectus," except that if
     any prospectus filed by the Company with the Commission pursuant to Rule
     424(b) of the Rules and Regulations or any other prospectus provided to
     the Underwriters by the Company for use in connection with the offering of
     the Securities (whether or not required to be filed by the Company with
     the Commission pursuant to Rule 424(b) of the Rules and Regulations)
     differs from the prospectus on file at the time the Registration Statement
     is or was declared effective by the Commission, the term "Prospectus"
     shall refer to such differing prospectus from and after the time such
     prospectus is filed with the Commission or transmitted to the Commission
     for filing pursuant to such Rule 424(b) or from and after the time it is
     first provided to the Underwriters by the Company for such use.  The term
     "Preliminary Prospectus" as used herein means any preliminary prospectus
     included in the Registration Statement prior to the time it becomes or
     became effective under the Act and any prospectus subject to completion as
     described in Rule 430A of the Rules and Regulations.

              2.      Representations and Warranties of the Company and the
     Selling Stockholders.

                      specifically for use in the preparation thereof.

                               (ii)    As of the time the Registration
                      Statement (or any post-effective amendment thereto) is or
                      was declared effective by the Commission, upon the filing
                      or first delivery to the Underwriters of the Prospectus
                      (or any supplement to the Prospectus) and at the First

                      requirements of the Act and the Rules and Regulations,
                      (B) the Registration Statement (as so amended) will not
                      or did not include an untrue statement of a material fact
                      or omit to state a material fact required to be stated
                      therein or necessary to make the statements therein not
                      misleading, and (C) the Prospectus (as so supplemented)
                      will not or did not include an untrue statement of a
                      material fact or omit to state a material fact required
                      to be stated therein or necessary to make the statements
                      therein, in light of the circumstances in which they are
                      or were made, not misleading; except that the foregoing
                      shall not apply to statements in or omissions from any
                      such document in reliance upon, and in conformity with,
                      written information furnished to the Company by you, or
                      by any Underwriter through you, specifically for use in
                      the preparation thereof.  If the Registration Statement
                      has been declared effective by the Commission, no stop
                      order suspending the effectiveness of the Registration
                      Statement has been issued, and no proceeding for that
                      purpose has been initiated or, to the Company's
                      knowledge, threatened by the Commission.

                               (iii)   The financial statements of the Company,

                      internal accounting controls sufficient to provide
                      reasonable assurances that (i) transactions are executed
                      in accordance with management's general or specific
                      authorization; (ii) transactions are recorded as
                      necessary to permit preparation of financial statements
                      in conformity with generally accepted accounting
                      principles and to maintain accountability for assets;
                      (iii) access to assets is permitted only in accordance
                      with management's general or specific authorization; and
                      (iv) the recorded accountability for assets is compared
                      with existing assets at reasonable intervals and
                      appropriate action is taken with respect to any
                      differences.

                               (xix)   To the best of the Company's knowledge,
                      each of the Company and its subsidiaries (A) is in
                      compliance with any and all applicable foreign, federal,
                      state and local laws and regulations relating to the
                      protection of human health and safety, the environment or
                      hazardous or toxic substances or wastes, pollutants or
                      contaminants ("Environmental Laws"), (B) has received all
                      permits, licenses or other approvals required of it under
                      applicable Environmental Laws to conduct its business and
                      (C) is in compliance with all terms and conditions of any
                      such permit, license or approval, except where such
                      noncompliance with Environmental Laws, failure to receive
                      required permits, licenses or other approvals or failure
                      to comply with the terms and conditions of such permits,
                      licenses or approvals would not, singly or in the
                      aggregate, have a material adverse effect on the
                      business, properties, financial condition or results of
                      operations of the Company and its subsidiaries, taken as
                      a whole.

                               (xx)    The Company is not, and upon receipt and
                      pending application of the net proceeds from the sale of
                      the Common Stock to be sold by the Company in the manner
                      described in the Prospectus will not be, an "investment
                      company" or an entity "controlled" by an "investment
                      company" as such terms are defined in the Investment
                      Company Act of 1940, as amended.

                               (xxi)   Each of the Company and its subsidiaries
                      maintains insurance of the types and in the amounts that
                      the Company believes are reasonably adequate for its
                      business, including, but not limited to, insurance
                      covering real and personal property owned or leased by
                      the Company and its subsidiaries against theft, damage,

                      destruction, acts of vandalism and all other risks
                      customarily insured against, all of which insurance is in
                      full force and effect.  The Company has not been refused
                      any insurance coverage sought or applied for; and the
                      Company has no reason to believe that it will not be able
                      to renew its existing insurance overage as and when such
                      coverage expires or to obtain similar coverage from
                      similar insurers as may be necessary to continue its
                      business at a cost that would not materially and
                      adversely affect the condition (financial or otherwise),
                      earnings, operations or business of the Company and its
                      subsidiaries taken as a whole.

                               (xxii)  Neither the Company nor any of its
                      subsidiaries has at any time during the last five (5)
                      years in any jurisdiction (i) made any unlawful
                      contribution to any candidate for office, or failed to
                      disclose fully any contribution in violation of law, or
                      (ii) made any payment to any governmental officer or
                      official or other person charged with similar public or
                      quasi-public duties other than payments required or
                      permitted by the laws of the United States.

                               (xxiii) Other than as contemplated by this
                      Agreement, the Company has not incurred any liability for
                      any finder's or broker's fee or agent's commission in
                      connection with the execution and delivery of this
                      Agreement or the consummation of the transactions
                      contemplated hereby.

                               (xxiv)  Neither the Company nor any of its
                      affiliates is presently doing business with the
                      government of Cuba or with any person or affiliate
                      located in Cuba.

                               (xxv)   The Company and its subsidiaries are not
                      involved in any labor dispute or disturbance nor, to the
                      knowledge of the Company, is any such dispute or
                      disturbance threatened.

                      (b)      Each Selling Stockholder severally and not
     jointly represents and warrants to, and agrees with, the Underwriters as
     follows:

                               (i)     Such Selling Stockholder is the record
                      and beneficial owner of, and has, and on the First
                      Closing Date and/or the Second Closing Date, as the case
                      may be (each as defined herein), will have, good, valid
                      and marketable title to the Securities to be sold by such
                      Selling Stockholder, free and clear of all security
                      interests, claims, liens, restrictions on
                      transferability, legends, proxies, equities or other

                      encumbrances; and upon delivery of and payment for such
                      Securities hereunder, the Underwriters will acquire valid
                      and marketable title thereto, free and clear of any
                      security interests, claims, liens, restrictions on
                      transferability, legends, proxies, equities or other
                      encumbrances.  Such Selling Stockholder is selling the
                      Securities to be sold by such Selling Stockholder for
                      such Selling Stockholder's own account, and no part of
                      the proceeds of such sale received by such Selling
                      Stockholder will inure, either directly or indirectly, to
                      the benefit of the Company other than as described in the
                      Registration Statement and Prospectus.

                               (ii)    Such Selling Stockholder has duly
                      authorized, executed and delivered a Power of Attorney
                      and Custody Agreement ("Custody Agreement"), which
                      Custody Agreement is a valid and binding obligation of
                      such Selling Stockholder, to ________________________, as
                      Custodian (the "Custodian"); pursuant to the Custody
                      Agreement the Selling Stockholder has placed in custody
                      with the Custodian, for delivery under this Agreement,
                      the certificates representing the Securities to be sold
                      by such Selling Stockholder; and such certificates were
                      duly and properly endorsed in blank for transfer, or were
                      accompanied by all documents duly and properly executed
                      that are necessary to effect the transfer to the
                      Underwriters of title thereto, free of any legend,
                      restriction on transferability, proxy, lien or claim,
                      whatsoever.

                               (iii)   Such Selling Stockholder has the power
                      and authority to enter into this Agreement and to sell,
                      transfer and deliver the Securities to be sold by such
                      Selling Stockholder; and such Selling Stockholder has
                      duly authorized, executed and delivered to
                      _______________ as attorney-in-fact (the
                      "Attorney-in-Fact"), an irrevocable power of attorney (a
                      "Power of Attorney") authorizing and directing the
                      Attorney-in-Fact, or any of them, to effect the sale and
                      delivery of the Securities being sold by such Selling
                      Stockholder, to enter into this Agreement and to take all
                      such other action as may be necessary hereunder.

                               (iv)    This Agreement, the Custody Agreement
                      and the Power of Attorney have each been duly authorized,
                      executed and delivered by or on behalf of such Selling
                      Stockholder and each constitutes a valid and binding
                      agreement of such Selling Stockholder, enforceable
                      against such Selling Stockholder in accordance with its
                      terms, except as rights to indemnity or contribution
                      hereunder or thereunder may be limited by federal or
                      state securities laws and except as such enforceability

                      may be limited by bankruptcy, insolvency, reorganization
                      or laws affecting the rights of creditors generally and
                      subject to general principles of equity.

                               (v)     Such Selling Stockholder owns the
                      Securities such Selling Stockholder is selling as an
                      individual or as a custodian for a minor, and not as a
                      trustee or in any other similar capacity.

                               (vi)    Such Selling Stockholder has not
                      distributed and will not distribute any prospectus or

                      and sale of the Securities other than any Preliminary
                      Prospectus or the Prospectus or other materials permitted
                      by the Act to be distributed by such Selling Stockholder.

                               (vii)   Such Selling Stockholder has not taken
                      and will not take, directly or indirectly any action
                      designed to, or which might reasonably be expected to,
                      cause or result in stabilization or manipulation of the
                      price of the Company's Common Stock, to facilitate the
                      sale or resale of the Securities.

     Company and delivered to you or to counsel for the Underwriters pursuant
     to this Agreement shall be deemed a representation and warranty by the
     Company to the Underwriters as to the matters covered thereby; any
     certificate signed by or on behalf of any Selling Stockholder as such and
     delivered to you or to counsel for the Underwriters pursuant to this
     Agreement shall be deemed a representation and warranty by such Selling
     Stockholder to the Underwriters as to the matters covered thereby.

              3.      Purchase, Sale and Delivery of Securities.
                      -----------------------------------------

                      (a)      On the basis of the representations, warranties
     and agreements herein contained, but subject to the terms and conditions
     herein set forth, the Company agrees to issue and sell ____ Firm Shares,
     to the Underwriters, and the Underwriters severally agree to purchase from
     the Company the number of Firm Shares set forth opposite the name of each
     Underwriter in Schedule I hereto.  The purchase price for each Firm Share
     shall be $___ per share.  The obligation of each Underwriter to the
     Company shall be to purchase from the Company that number of Firm Shares
     (to be adjusted by the Representatives to avoid fractional shares) which
     represents the same proportion of the number of Firm Shares to be sold by
     the Company pursuant to this Agreement as the number of Firm Shares set
     forth opposite the name of such Underwriter in Schedule I hereto
     represents to the total number of Firm Shares to be purchased by all
     Underwriters pursuant to this Agreement.  In making this Agreement, each
     Underwriter is contracting severally and not jointly; except as provided
     in paragraphs (b) and (d) of this Section 3 and in Section 8 hereof, the


                                        - 12 -
<PAGE>






     agreement of each Underwriter is to purchase only the respective number of
     Firm Shares specified in Schedule I.

                      The Firm Shares will be delivered by the Company to you
     for the accounts of the several Underwriters against payment of the
     purchase price therefor by certified or official bank check or other next
     day funds payable to the order of the Company at the offices of Piper
     Jaffray Inc., Piper Jaffray Tower, 222 South Ninth Street, Minneapolis,
     MN, 55402 or such other location as may be mutually acceptable, at 9:00
     a.m. Minneapolis time on the third full business day (or, if the Firm
     Shares are priced as contemplated by Rule 15c6-1(c) of the Exchange Act,
     after 4:30 p.m., Washington, D.C. time, the fourth full business day)
     following the date hereof, or at such other time as you and the Company
     determine, such time and date of delivery being herein referred to as the
     "First Closing Date."  The Firm Shares, in definitive form and in such
     denominations and registered in such names as you may request upon at
     least two business days' prior notice to the Company, will be made
     available for checking and packaging at the offices of Piper Jaffray Inc.,
     Piper Jaffray Tower, 222 South Ninth Street, Minneapolis, MN, 55402 or
     such other location as may be mutually acceptable, at least one business
     day prior to the First Closing Date.  The Company shall instruct the bank
     at which the check is deposited that the funds are not to be made
     available to the Company (nor transferred from the account of the
     Underwriters) prior to the first business day following the First Closing
     Date.  In this regard, the Company agrees not to deposit any such check in
     the bank on which it is drawn earlier than the first business day
     following the First Closing Date (if such deposit would have the purpose
     or effect of receiving immediately available funds or earning interest on
     such funds) and further agrees not to take any other action with the
     purpose or effect of receiving immediately available funds or earning
     interest on such funds until the first business day following the First
     Closing Date.  In the event of any breach of the foregoing, the Company
     shall reimburse the Underwriters for the interest lost and any other
     expenses borne by the Underwriters by reason of such breach.

                      (b)      If for any reason one or more of the Underwriters
     shall fail or refuse (otherwise than for a reason sufficient to justify
     the termination of this Agreement under the provisions of Section 9 or 10
     hereof) to purchase and pay for the number of Firm Shares agreed to be
     purchased by such Underwriter or Underwriters, the Company shall
     immediately give notice thereof to each other Underwriter, and the non-
     defaulting Underwriters shall have the right within 24 hours after the
     receipt of such notice to purchase, or procure one or more other
     Underwriters to purchase, in such proportions as may be agreed upon
     between the non-defaulting Underwriters and such purchasing Underwriter or
     Underwriters and upon the terms herein set forth, all or any part of the
     Firm Shares which such defaulting Underwriter or Underwriters agreed to
     purchase. If the non-defaulting Underwriters fail so to make such
     arrangements with respect to all such shares and portion, the number of
     Firm Shares which each non-defaulting Underwriter is otherwise obligated
     to purchase under this Agreement shall be automatically increased on a pro
     rata basis to absorb the remaining shares and portion which the defaulting

                                        - 13 -
<PAGE>






     Underwriter or Underwriters agreed to purchase; provided, however, that
     the non-defaulting Underwriters shall not be obligated to purchase the
     shares and portion which the defaulting Underwriter or Underwriters agreed
     to purchase if the aggregate number of such shares exceeds 10% of the
     total number of Firm Shares, which all Underwriters agreed to purchase
     hereunder.  If the total number of Firm Shares which the defaulting
     Underwriter or Underwriters agreed to purchase shall not be purchased or
     absorbed in accordance with the two proceeding sentences, the Company
     shall have the right to postpone the First Closing Date determined as
     provided in Section 3(a) hereof for not more than seven business days
     after the date originally fixed as the First Closing Date pursuant to said
     Section 3(a) in order that any necessary changes in the Registration
     Statement, the Prospectus or any other documents or arrangements may be
     made.  If neither the non-defaulting Underwriters nor the Company shall
     make arrangements within the 24-hour period stated above for the purchase
     of all of the Firm Shares which the defaulting Underwriter or Underwriters
     agreed to purchase hereunder, this Agreement shall be terminated without
     further act or deed and without any liability on the part of the Company
     to any non-defaulting Underwriter and without any liability on the part of
     any non-defaulting Underwriter to the Company.  Nothing in this paragraph
     (b), and no action taken hereunder, shall relieve any defaulting
     Underwriter from liability in respect of any default of such Underwriter
     under this Agreement.

                      (c)      On the basis of the representations, warranties
     and agreements herein contained, but subject to the terms and conditions
     herein set forth, the Company and the Selling Stockholders hereby grant to
     the several Underwriters an option to purchase all or any portion of the
     Option Shares at the same purchase price as the Firm Shares, for use
     solely in covering any over-allotments made by the Underwriters in the
     sale and distribution of the Firm Shares.  The option granted hereunder
     may be exercised at any time (but not more than once) within 30 days after
     the effective date of this Agreement upon notice (confirmed in writing) by
     the Representatives to the Company and the Custodian setting forth the
     aggregate number of Option Shares as to which the several Underwriters are
     exercising the option, the names and denominations in which the
     certificates for the Option Shares are to be registered and the date and
     time, as determined by you, when the Option Shares are to be delivered,
     such time and date being herein referred to as the "Second Closing" and
     "Second Closing Date", respectively; provided, however, that the Second
     Closing Date shall not be earlier than the First Closing Date nor earlier
     than the second business day after the date on which the option shall have
     been exercised.  If the option granted hereunder is exercised, the number
     of Option Shares to be purchased by each Underwriter shall be the same
     percentage of the total number of Option Shares to be purchased by the
     several Underwriters as the number of Firm Shares to be purchased by such
     Underwriter is of the total number of Firm Shares to be purchased by the
     several Underwriters, as adjusted by the Representatives in such manner as
     the Representatives deem advisable to avoid fractional shares.  If the
     option is exercised in part, the respective number of Option Shares to be
     sold by the Company and the Selling Stockholders shall be in the same
     proportion to the aggregate number of Option Shares to be sold as the

                                        - 14 -

     maximum number of Option Shares to be sold by each of the Company and the
     Selling Stockholders bears to the total number of Option Shares, as
     adjusted by the Representatives in such a manner as they deem advisable to
     avoid fractional shares.  No Option Shares shall be sold and delivered
     unless the Firm Shares previously have been, or simultaneously are, sold
     and delivered.

                      The Option Shares will be delivered by the Company and
     the Custodian to you for the accounts of the several Underwriters against
     payment of the purchase price therefor by certified or official bank check
     or other next day funds payable to the order of the Company or the
     Custodian, as appropriate, at the offices of Piper Jaffray Inc., Piper
     Jaffray Tower, 222 South Ninth Street, Minneapolis, MN, 55402 or such
     other location as may be mutually acceptable at 9:00 a.m. Minneapolis time
     on the Second Closing Date.  The Option Shares in definitive form and in
     such denominations and registered in such names as you have set forth in
     your notice of option exercise, will be made available for checking and
     packaging at the office of Piper Jaffray, Inc., Piper Jaffray Tower, 222
     South 9th Street, Minneapolis, MN, 55402 or such other location as may be
     mutually acceptable, at least one business day prior to the Second Closing
     Date.  The Company and the Custodian shall instruct the respective banks
     at which the checks are deposited that the funds are not to be made
     available to the Company or the Custodian, as the case may be, (nor
     transferred from the account of the Underwriters) prior to the first
     business day following the Second Closing Date.  In this regard, each of
     the Company and the Custodian agree not to deposit any such check in the
     bank on which it is drawn earlier than the first business day following
     the Second Closing Date (if such deposit would have the purpose or effect
     of receiving immediately available funds or earning interest on such
     funds) and further agrees not to take any other action with the purpose or
     effect of receiving immediately available funds or earning interest on
     such funds until the first business day following the Second Closing Date. 
     In the event of any breach of the foregoing, the Company shall reimburse
     the Underwriters for the interest lost and any other expenses borne by the
     Underwriters by reason of such breach.

                      (d)      It is understood that you, individually and not
     as Representatives of the several Underwriters, may (but shall not be
     obligated to) make payment to the Company on behalf of any Underwriter for
     the Securities to be purchased by such Underwriter.  Any such payment by
     you shall not relieve any such Underwriter of any of its obligations
     hereunder.  Nothing herein contained shall constitute any of the
     Underwriters an unincorporated association or partner with the Company.

              4.      Covenants.
                      ---------

                      thereto to become effective as promptly as possible; the
                      Company will notify you promptly of the time when the
                      Registration Statement or any post-effective amendment to
                      the Registration Statement has become effective or any
                      supplement to the Prospectus has been filed and of any
                      request by the Commission for any amendment or supplement
                      to the Registration Statement or Prospectus or additional
                      information; if the Company has elected to rely on Rule
                      430A of the Rules and Regulations or the filing of the
                      Prospectus is otherwise required under Rule 424(b) of the
                      Rules and Regulations, the Company will file a Prospectus
                      containing the information omitted therefrom pursuant to
                      such Rule 430A or otherwise with the Commission within
                      the time period required by, and otherwise in accordance
                      with the provisions of, Rule 424(b) and, if applicable,
                      Rule 430A of the Rules and Regulations; the Company will
                      prepare and file with the Commission, promptly upon your
                      request, any amendments or supplements to the
                      Registration Statement or Prospectus that, in your
                      opinion, may be necessary or advisable in connection with
                      the distribution of the Securities by the Underwriters;
                      and the Company will not file any amendment or supplement
                      to the Registration Statement or Prospectus to which you
                      or your counsel shall reasonably object by notice to the
                      Company after having been furnished a copy a reasonable
                      time prior to the filing.

                               (ii)    The Company will advise you, promptly
                      after it shall receive notice or obtain knowledge
                      thereof, of the issuance by the Commission of any stop
                      order suspending the effectiveness of the Registration
                      Statement or suspending the use of the Prospectus, of the
                      suspension of the qualification of the Securities for
                      offering or sale in any jurisdiction, or of the
                      initiation or threatening of any proceeding for any such
                      purpose; and the Company will promptly use its best
                      efforts to prevent the issuance of any stop order or to
                      obtain its withdrawal at the earliest possible moment if
                      such a stop order should be issued.

                               (iii)   Within the time during which a
                      prospectus relating to the Securities is required to be
                      delivered under the Act, the Company will comply with all
                      requirements imposed upon it by the Act, as now and
                      hereafter amended, and by the Rules and Regulations, as
                      from time to time in force, so far as necessary to permit
                      the continuance of sales of or dealings in the Securities
                      as contemplated by the provisions hereof and the
                      Prospectus.  If during such period any event occurs as a
                      result of which the Prospectus or any other prospectus

                                        - 16 -

                      include an untrue statement of a material fact or omit to
                      state a material fact necessary to make the statements
                      therein, in the light of the circumstances then existing,
                      not misleading, or if during such period it is necessary
                      to amend the Registration Statement or supplement the
                      Prospectus to comply with the Act, the Company will
                      promptly notify you and will promptly amend the
                      Registration Statement or supplement the Prospectus (at
                      the expense of the Company) so as to correct such
                      statement or omission or effect such compliance.

                               (iv)    The Company will use its best efforts to
                      qualify the Securities for offering and sale under the
                      securities laws of such jurisdictions as you reasonably
                      designate and to continue such qualifications in effect
                      so long as required for the distribution of the
                      Securities, except that the Company shall not be required
                      in connection therewith to qualify as a foreign
                      corporation or to execute a general consent to service of
                      process in any state. 

                               (v)     The Company will furnish to the
                      Underwriters copies of the Registration Statement (four
                      of which will be signed and will include all exhibits),
                      and each Preliminary Prospectus, and all amendments and
                      supplements to such documents, in each case as soon as
                      available and in such quantities as you may from time to
                      time reasonably request. The Company will furnish the
                      Underwriters with copies of the Prospectus in Minneapolis
                      prior to 10:00 a.m., Minneapolis time, on the business
                      day next succeeding the date of this Agreement.

                               (vi)    During a period of five years commencing
                      with the date hereof, the Company will furnish to the
                      Representatives, and to each Underwriter who may so
                      request in writing, copies of all periodic and special
                      reports furnished to the stockholders of the Company and
                      all information, documents and reports filed with the
                      Commission, the National Association of Securities
                      Dealers, Inc., the Nasdaq National Market or any
                      securities exchange.

                      period beginning after the effective date of the
                      Registration Statement that shall satisfy the provisions
                      of Section 11(a) of the Act and Rule 158 of the Rules and

                      transactions contemplated hereunder are consummated or

                               (ix)    The Company will apply the net proceeds
                      from the sale of the Securities to be sold by it
                      hereunder for the purposes set forth in the Prospectus
                      under "Use of Proceeds" and will file such reports with
                      the Commission with respect to the sale of the Securities
                      and the application of the proceeds therefrom as may be
                      required in accordance with Rule 463 of the Rules and
                      Regulations.

                               (x)     The Company will not, without the  prior
                      written consent of the Representatives, offer for sale,
                      sell, contract to sell, grant any option for the sale of
                      or otherwise issue or dispose of any Common Stock or any
                      securities convertible into or exchangeable for, or any
                      options or rights to purchase or acquire, Common Stock,
                      for a period of 180 days after the commencement of the
                      public offering of the Securities by the Underwriters,
                      except (i) to the Underwriters pursuant to this
                      Agreement, or (ii) upon the exercise of outstanding stock
                      options under the Company's 1996 Stock Incentive Plan
                      (the "1996 Stock Incentive Plan") described in the
                      Registration Statement and Prospectus.  The Company will
                      not, without the prior consent of the Representatives or
                      unless subject to the Lock-Up Agreements (as more fully
                      described in Section 4(a)(xi) below), grant any new
                      option under the 1996 Stock Incentive Plan which becomes
                      exercisable during such 180 day period.  The foregoing
                      restriction is expressly agreed to preclude the Company
                      from engaging in any hedging or other transaction which
                      is designed to or reasonably expected to lead to or
                      result in such disposition during such 180 day period
                      even if such shares of Common Stock or such options or
                      rights to purchase or acquire Common Stock would be
                      disposed of by someone other than the Company.  Such
                      prohibited hedging or other transactions would include,
                      without limitation, any short sale (whether or not
                      against the box) or any purchase, sale or grant of any
                      right (including, without limitation, any put or call
                      option) with respect to any such shares of Common Stock
                      or such options or rights or with respect to any security
                      (other than a broad-based market basket or index) that
                      includes, relates to or derives any significant part of
                      its value from such shares of Common Stock or such
                      options or rights. 

                               (xi)    The Company either has caused to be
                      delivered to you or will cause to be delivered to you
                      prior to the effective date of the Registration Statement
                      true, accurate and complete copies of agreements

                      directors, officers, stockholders and holders of
                      outstanding options and warrants to purchase Common Stock
                      on the date of this Agreement stating that such person
                      agrees that he or she will not, without your prior

                      public offering of the Securities by the Underwriters. 

                               (xii)   The Company has not taken and will not
                      take, directly or indirectly, any action designed to or
                      which might reasonably be expected to cause or result in,
                      or which has constituted, the stabilization or
                      manipulation of the price of any security of the Company
                      to facilitate the sale or resale of the Securities, and
                      has not effected any sales of Common Stock which are
                      required to be disclosed in response to Item 701 of
                      Regulation S-K under the Act which have not been so
                      disclosed in the Registration Statement.

                               (xiii)  The Company will not incur any liability
                      for any finder's or broker's fee or agent's commission in
                      connection with the execution and delivery of this
                      Agreement or the consummation of the transactions
                      contemplated hereby.

                               (xiv)   The Company will inform the Florida
                      Department of Banking and Finance at any time prior to
                      the consummation of the distribution of the Securities by
                      the Underwriters if it commences engaging in business
                      with the government of Cuba or with any person or
                      affiliate located in Cuba.  Such information will be
                      provided within 90 days after the commencement thereof or
                      after a change occurs with respect to previously reported
                      information.

                               (xv)    The Company will maintain a transfer
                      agent and, if necessary under the jurisdiction of
                      incorporation of the Company, a registrar (which may be
                      the same entity as the transfer agent) for its Common
                      Stock.  

                               (xvi)   The Company is familiar with the
                      Investment Company Act of 1940, as amended, and the rules
                      and regulations thereunder, and has in the past conducted
                      its affairs and will in the future conduct its affairs,
                      in such a manner so as to insure that the Company was not
                      and will not be an "Investment Company" within the

                      meaning of the Investment Company Act of 1940 and the
                      rules and regulations promulgated thereunder.

                      (b)      Each Selling Stockholder covenants and agrees
     with the Underwriters as follows:

                               (i)     Such Selling Stockholder will pay all
                      taxes, if any, on the transfer and sale, respectively, of
                      the Securities being sold by such Selling Stockholder and
                      except as otherwise agreed to by the Company and the
                      Selling Stockholder, the fees of such Selling
                      Stockholder's counsel if such Selling Stockholder elects
                      to be represented by counsel other than Company counsel;
                      provided, however, that each Selling Stockholder
                      severally agrees to reimburse the Company for any
                      reimbursement made by the Company to the Underwriters
                      pursuant to Section 4(a)(viii) hereof to the extent such
                      reimbursement resulted from the failure or refusal on the
                      part of such Selling Stockholder to comply under the
                      terms or fulfill any of the conditions of this Agreement,
                      which failure or refusal arises out of or results from
                      (A) the breach by such Selling Stockholder of any
                      representation or warranty herein or in such Selling
                      Stockholder's Power of Attorney, or (B) any act taken or
                      attempted to be taken by such Selling Stockholder in its
                      own right and in derogation of the authority granted by
                      such Selling Stockholder in such Power of Attorney.

                               (ii)    The Securities to be sold by such
                      Selling Stockholder, represented by the certificates on
                      deposit with the Custodian pursuant to the Custody
                      Agreement of such Selling Stockholder, are subject to the
                      interest of the Underwriters and the other Selling
                      Stockholders; the arrangements made for such custody are,
                      except as specifically provided in the Custody Agreement,
                      irrevocable; and the obligations of such Selling
                      Stockholder hereunder shall not be terminated, except as
                      provided in this Agreement or in the Custody Agreement,
                      by any act of such Selling Stockholder, by operation of
                      law, whether by the liquidation, dissolution or merger of
                      such Selling Stockholder, by the death of such Selling
                      Stockholder, or by the occurrence of any other event.  If
                      any Selling Stockholder should liquidate, dissolve or be
                      a party to a merger or if any other such event should
                      occur before the delivery of the Securities hereunder,
                      certificates for the Securities deposited with the
                      Custodian shall be delivered by the Custodian in
                      accordance with the terms and conditions of this
                      Agreement as if such liquidation, dissolution, merger or
                      other event had not occurred, whether or not the
                      Custodian shall have received notice thereof.

                               (iii)   Such Selling Stockholder will not,
                      without your prior written consent, offer for sale, sell,
                      contract to sell, grant any option for the sale of or
                      otherwise dispose of any Common Stock or any securities
                      convertible into or exchangeable for, or any options or
                      rights to purchase or acquire, Common Stock, except (i)
                      to the Underwriters pursuant to this Agreement and (ii)
                      exercises of options, for the period of 180 days after
                      the commencement of the public offering of the Securities
                      by the Underwriters as set forth in such Selling
                      Stockholder's respective Lock-Up Agreement, which
                      Agreement has been delivered to you prior to the
                      effective date of the Registration Statement.  Each
                      Selling Stockholder agrees and consents to the entry of
                      stop transfer instructions with the Company's transfer
                      agent against the transfer of shares of Common Stock held
                      by such Selling Stockholder, except in accordance with
                      the terms hereof.

                               (iv)    Such Selling Stockholder has not taken
                      and will not take, directly or indirectly, any action
                      designed to or which might reasonably be expected to
                      cause or result in stabilization or manipulation of the
                      price of any security of the Company to facilitate the
                      sale or resale of the Securities.

                               (v)     Such Selling Stockholder shall
                      immediately notify you if any event occurs, or of any
                      change in information relating to such Selling
                      Stockholder or the Company or any new information
                      relating to the Company or relating to any matter stated
                      in the Prospectus or any supplement thereto, which
                      results in the Prospectus (as supplemented) including an
                      untrue statement of a material fact or omitting to state
                      any material fact necessary to make the statements
                      therein, in light of the circumstances under which they
                      were made, not misleading to the extent such event or
                      change relates to written information specifically
                      provided to the Company by such Selling Stockholders for
                      use in the Prospectus.

              5.      Conditions of Underwriters' Obligations.  The obligations
     of the several Underwriters hereunder are subject to the accuracy, as of
     the date hereof and at each of the First Closing Date and the Second
     Closing Date (as if made at such Closing Date), of and compliance with all
     representations, warranties and agreements of the Company and the Selling
     Stockholders contained herein, to the performance by the Company and the
     Selling Stockholders of their respective obligations hereunder and to the
     following additional conditions:

                      (a)      The Registration Statement shall have become
     effective not later than 5:00 p.m., Minneapolis time, on the date of this

                                        - 22 -
<PAGE>






     Agreement, or such later time and date as you, as Representatives of the
     several Underwriters, shall approve and all filings required by Rule 424
     and Rule 430A of the Rules and Regulations shall have been timely made; no
     stop order suspending the effectiveness of the Registration Statement or
     any amendment thereof shall have been issued; no proceedings for the
     issuance of such an order shall have been initiated or threatened; and any
     request of the Commission for additional information (to be included in
     the Registration Statement or the Prospectus or otherwise) shall have been
     complied with to your satisfaction.

                      (b)      No Underwriter shall have advised the Company
     that the Registration Statement or the Prospectus, or any amendment
     thereof or supplement thereto, contains an untrue statement of fact which,
     in your opinion, is material, or omits to state a fact which, in your
     opinion, is material and is required to be stated therein or necessary to
     make the statements therein not misleading.

                      (c)      Except as contemplated in the Prospectus,
     subsequent to the respective dates as of which information is given in the
     Registration Statement and the Prospectus, neither the Company nor any of
     its subsidiaries shall have incurred any material liabilities or
     obligations, direct or contingent, or entered into any material
     transactions, or declared or paid any dividends or made any distribution
     of any kind with respect to its capital stock; and there shall not have
     been any change in the capital stock (other than a change in the number of
     outstanding shares of Common Stock due to the issuance of shares upon the
     exercise of outstanding options under the 1996 Stock Incentive Plan), or
     any material change in the short-term or long-term debt of the Company, or
     any issuance of options, warrants, convertible securities or other rights
     to purchase the capital stock of the Company or any of its subsidiaries,
     or any material adverse change or any development likely to involve a
     prospective material adverse change (whether or not arising in the
     ordinary course of business), in the general affairs, condition (financial
     or otherwise), business, key personnel, property, prospects, net worth or
     results of operations of the Company and its subsidiaries, taken as a
     whole, that, in your judgment, makes it impractical or inadvisable to
     offer or deliver the Securities on the terms and in the manner
     contemplated in the Prospectus.

                      (d)      On each Closing Date, there shall have been
     furnished to you, as Representatives of the several Underwriters, the
     opinion of  Kirkpatrick & Lockhart L.L.P., counsel for the Company, dated
     such Closing Date and addressed to you, in form and substance satisfactory
     to you, to the effect that:

                               (i)     Each of the Company and its subsidiaries
                      has been duly organized and is validly existing as a
                      corporation in good standing under the laws of its
                      jurisdiction of incorporation.  Each of the Company and
                      its subsidiaries has full corporate power and authority
                      to own its properties and conduct its business as
                      currently being carried on and as described in the

                                        - 23 -
<PAGE>






                      Registration Statement and Prospectus, and is duly
                      qualified to do business as a foreign corporation and is
                      in good standing in each jurisdiction in which it owns or
                      leases real property or in which the conduct of its
                      business makes such qualification necessary and in which
                      the failure to so qualify would have a material adverse
                      effect upon the business, condition (financial or
                      otherwise) or properties of the Company and its
                      subsidiaries, taken as a whole.

                               (ii)    The capital stock of the Company
                      conforms as to legal matters to the description thereof
                      contained in the Prospectus under the caption
                      "Description of Capital Stock."  All of the issued and
                      outstanding shares of the capital stock of the Company
                      have been duly authorized and validly issued and are
                      fully paid and nonassessable, and the holders thereof are
                      not subject to personal liability by reason of being such
                      holders.  All outstanding shares of the Company's capital
                      stock and all outstanding options to purchase the
                      Company's capital stock were issued in compliance in all
                      material respects with the registration and qualification
                      requirements of all applicable federal and state
                      securities laws.  The Securities to be issued and sold by
                      the Company hereunder have been duly authorized and, when
                      issued, delivered and paid for in accordance with the
                      terms of this Agreement, will have been validly issued
                      and will be fully paid and nonassessable, and the holders
                      thereof will not be subject to personal liability by
                      reason of being such holders.  Except as otherwise stated
                      in the Registration Statement and Prospectus, there are
                      no preemptive rights or other rights to subscribe for or
                      to purchase, or any restriction upon the voting or
                      transfer of, any shares of Common Stock pursuant to the
                      Company's charter, by-laws or any agreement or other
                      instrument known to such counsel to which the Company is
                      a party or by which the Company is bound.  To the best of
                      such counsel's knowledge, neither the filing of the
                      Registration Statement nor the offering or sale of the
                      Securities as contemplated by this Agreement gives rise
                      to any rights for or relating to the registration of any
                      shares of Common Stock or other securities of the
                      Company.

                               (iii)   All of the issued and outstanding shares
                      of capital stock of each of the Company's subsidiaries
                      have been duly and validly authorized and issued and are
                      fully paid and nonassessable, and, except as otherwise
                      described in the Registration Statement and Prospectus
                      and except for directors' qualifying shares, the Company
                      owns of record and beneficially, free and clear of any
                      security interests, claims, liens, proxies, equities or

                                        - 24 -
<PAGE>






                      other encumbrances, all of the issued and outstanding
                      shares of such stock.  To the best of such counsel's
                      knowledge, except as described in the Registration
                      Statement and Prospectus, there are no options, warrants,
                      agreements, contracts or other rights in existence to
                      purchase or acquire from the Company or any subsidiary
                      any shares of the capital stock of the Company or any
                      subsidiary of the Company.

                               (iv)    The Registration Statement has become
                      effective under the Act and, to the best of such
                      counsel's knowledge, no stop order suspending the
                      effectiveness of the Registration Statement has been
                      issued and no proceeding for that purpose has been
                      instituted or, to the knowledge of such counsel,
                      threatened by the Commission; any required filing of the
                      Prospectus and any supplement thereto pursuant to Rule

                      manner and within the time period required by Rule
                      424(b).

                               (v)     The descriptions in the Registration
                      Statement and Prospectus of statutes, legal and
                      governmental proceedings, contracts and other documents
                      are accurate and fairly present the information required
                      to be disclosed with respect thereto; and such counsel
                      does not know of any statutes or legal or governmental
                      proceedings required to be described in the Prospectus
                      that are not described as required, or of any contracts
                      or documents of a character required to be described in
                      the Registration Statement or Prospectus or included as

                      and deliver to the several Underwriters the Securities to

                      been duly authorized, executed and delivered by the
                      Company and constitutes a valid, legal and binding
                      obligation of the Company enforceable against the Company
                      in accordance with its terms (except as rights to
                      indemnity and contribution hereunder may be limited by
                      federal or state securities laws and except as such
                      enforceability may be limited by bankruptcy, insolvency,
                      reorganization or similar laws affecting the rights of
                      creditors generally and subject to general principles of

                      Agreement and the consummation of the transactions herein
                      contemplated will not result in a breach or violation of

                      respective properties; and no consent, approval,
                      authorization or order of, or filing with, any court or
                      governmental agency or body is required for the
                      execution, delivery and performance of this Agreement or

                      hereby, including the issuance or sale of the Securities
                      by the Company, except such as may be required under the
                      Act or state securities laws.

                               (vii)   To the best of such counsel's knowledge,
                      the Company and each of its subsidiaries holds, and is
                      operating in compliance in all material respects with,
                      all franchises, grants, authorizations, licenses,

                      any governmental or self-regulatory body required for the
                      conduct of its business and all such franchises, grants,
                      authorizations, licenses, permits, easements, consents,

                               (viii)  To the best of such counsel's knowledge,
                      neither the Company nor any of its subsidiaries is in
                      violation of its respective charter or by-laws. To the
                      best of such counsel's knowledge, neither the Company nor
                      any of its subsidiaries is in breach of or otherwise in
                      default in the performance of any material obligation,
                      agreement or condition contained in any bond, debenture,
                      note, contract, indenture, loan agreement, permit,
                      approval, registration, judgment, decree, order, statute,
                      rule or regulation or any other contract, lease or other
                      instrument to which it is subject or by which any of them
                      may be bound, or to which any of the material property or
                      assets of the Company or any of its subsidiaries is
                      subject.

                               (ix)    The Registration Statement and the
                      Prospectus, and any amendment thereof or supplement
                      thereto, comply as to form in all material respects with
                      the requirements of the Act and the Rules and
                      Regulations, and on the basis of conferences with
                      officers of the Company, examination of documents

                      appropriate, nothing has come to the attention of such
                      counsel which causes such counsel to believe that the
                      Registration Statement or any amendment thereof, at the
                      time the Registration Statement became effective and as
                      of such Closing Date, contained any untrue statement of a
                      material fact or omitted to state any material fact
                      required to be stated therein or necessary to make the
                      statements therein not misleading or that the Prospectus
                      (as of its date and as of such Closing Date), as amended
                      or supplemented, includes any untrue statement of
                      material fact or omits to state a material fact necessary
                      to make the statements therein, in light of the
                      circumstances under which they were made, not misleading;
                      it being understood that such counsel need express no
                      opinion as to the financial statements and notes thereto,
                      financial statement schedules and other financial and
                      statistical data included in any of the documents
                      mentioned in this clause.

                               (x)     Except as set forth in the Registration
                      Statement and Prospectus, such counsel knows of no
                      pending or threatened action, suit, claim, proceeding or
                      investigation before any court or governmental agency or
                      body that, if determined adversely to the Company, would
                      have a material adverse effect on the Company and its
                      subsidiaries, taken as a whole, or which would limit,
                      revoke, cancel, suspend, or cause not be renewed any
                      existing license, certificate, registration, approval or
                      permit from any state, federal or regulatory authority
                      that is material to the conduct of the business or the
                      Company and its subsidiaries, taken as a whole, as
                      presently conducted.

                               (xi)    To the best of such counsel's knowledge,
                      no holders of shares of Common Stock or other securities
                      of the Company have registration rights with respect to
                      securities of the Company, other than as described in the
                      Prospectus.  

                               (xii)   The Company is not an "Investment
                      Company" within the meaning of the Investment Company Act
                      of 1940, as amended, and the rules and regulations
                      thereunder.

                               (xiii)  The statements under the captions
                      "Certain Transactions", "Description of Capital Stock"
                      and "Shares Eligible for Future Sale" in the Prospectus
                      and in Items 14 and 15 of the Registration Statement,
                      insofar as such statements constitute  a summary of
                      documents referred to therein or of matters of law, are
                      accurate summaries and fairly and correctly present the

                      matters.

                               (xiv)   The statements in the Prospectus under
                      the captions "Risk Factors Pending Litigation" and
                      "Business Legal Proceedings" fairly summarize the legal
                      matters, documents and proceedings referred to therein.

                               (xv)    Such other matters as you may reasonably
                      request.

                      In rendering such opinion such counsel may rely (i) as to
     matters of law other than the law of the District of Columbia and federal
     law, upon the opinion or opinions of local counsel provided that the
     extent of such reliance is specified in such opinion and that such counsel
     shall state that such opinion or opinions of local counsel are
     satisfactory to them and that they believe they and you are justified in
     relying thereon and (ii) as to matters of fact, to the extent such counsel
     deems reasonable upon certificates of officers of the Company and its
     subsidiaries provided that the extent of such reliance is specified in
     such opinion.  Copies of any opinion or certificate relied upon shall be
     delivered to you, as Representatives of the Underwriters.

                      (e)      On each Closing Date, there shall have been
     furnished to you, as Representatives of the several Underwriters, the
     opinion of ____________________, [intellectual property] counsel for the

                               (i)     To the best of such counsel's knowledge,
                      neither the Registration Statement nor the Prospectus
                      contains any untrue statement of a material fact with
                      respect to the Intellectual Property owned or used by the
                      Company or omits to state any material fact relating to
                      Intellectual Property owned or used by the Company that
                      is required to be stated in the Registration Statement or
                      the Prospectus or that is necessary to make the
                      statements therein not misleading;

                               (ii)    To the best of such counsel's knowledge,
                      there are no legal or governmental proceedings pending
                      relating to Intellectual Property other than prosecution
                      by the Company of its patent applications before the
                      United States Patent and Trademark Office and appropriate
                      foreign government agencies, and to the best of such
                      counsel's knowledge, no such proceedings are threatened
                      or contemplated by governmental authorities or others;

                               (iii)   The Company has duly and properly filed
                      patent applications and patent cooperation treaty
                      applications, listed or otherwise referred to in the

                      Prospectus under the caption "BUSINESS - Patents,
                      Proprietary Technology, Trademarks and Licenses";

                               (iv)    Such counsel do not know of any
                      contracts or other documents relating to the Company's
                      Intellectual Property of a character required to be filed
                      as an exhibit to the Registration Statement or required
                      to be described in the Registration Statement or the
                      Prospectus that are not filed or described as required.

                               (v)     To the best of such counsel's knowledge,
                      the Company is not infringing or otherwise violating any
                      trademarks, trade names, patents, mask works, copyrights,
                      licenses, trade secrets or other intellectual property
                      rights of others and, to the best of such counsel's
                      knowledge, there are no infringements by others of any of
                      the Company's Intellectual Property which in the judgment
                      of such counsel would have a material adverse effect upon
                      the business condition (financial or otherwise) or
                      properties of the Company and its subsidiaries, taken as
                      a whole; and

                               (vi)    To the best of such counsel's knowledge,
                      the Company owns or possesses sufficient licenses or
                      other rights to use all Intellectual Property necessary
                      to conduct the business now being or proposed to be
                      conducted by the Company as described in the Prospectus.

                      In rendering such opinion, such counsel may, to the
     extent stated therein, rely as to matters of fact on certificates of
     officers of the Company, copies of which shall be attached to the opinion. 
     In rendering such opinion, such counsel need not have conducted any
     independent investigation or conducted searches to locate any third party
     patents, mask works, copyrights or other intellectual property rights that
     might impact the Company's activities, unless such counsel has knowledge
     of any actual, potential or alleged infringement.

     furnished to you the opinion of ____________________, dated such Closing
     Date and addressed to you, to the effect that:

                      owner of the Securities to be sold by such Selling
                      Stockholder; upon registration of the Securities in the
                      names of the Underwriters in the stock records of the
                      Company, the Underwriters will acquire all the rights of
                      such Selling Stockholder in the Securities (assuming the
                      Underwriters purchased the Securities in good faith and
                      without notice of an adverse claim), free and clear of
                      any adverse claim, lien in favor of the Company and
                      restrictions on transfer imposed by the Company.

                      authority to enter into the Custody Agreement, the Power
                      of Attorney and this Agreement and to perform and

                      Attorney-in-Fact, or any of them, on behalf of) the
                      Selling Stockholders.

              In rendering such opinion such counsel may rely as to matters of
     fact, to the extent such counsel deems reasonable upon certificates of the
     Attorney-in-Fact or Selling Stockholders.   Copies of any opinion or
     certificate relied upon shall be delivered to you.

                      (g)      On each Closing Date, there shall have been
     furnished to you, as Representatives of the several Underwriters, such
     opinion or opinions from Goodwin, Procter & Hoar LLP, counsel for the
     several Underwriters, dated such Closing Date and addressed to you, with

                      complied with all the agreements and satisfied all the
                      conditions on its part to be performed or satisfied at or
                      prior to such Closing Date;

                               (ii)    The Registration Statement has become
                      effective and no stop order or other order suspending the
                      effectiveness of the Registration Statement or any
                      amendment thereof or the qualification of the Securities
                      for offering or sale has been issued, and no proceeding
                      for that purpose has been instituted or, to the best of
                      their knowledge, is contemplated by the Commission or any
                      state or regulatory body; and

                               (iii)   The signers of said certificate have
                      carefully examined the Registration Statement and the
                      Prospectus, and any amendments thereof or supplements
                      thereto, and (A) such documents contain all statements
                      and information required to be included therein, the
                      Registration Statement, or any amendment thereof, does
                      not contain any untrue statement of a material fact or
                      omit to state any material fact required to be stated
                      therein or necessary to make the statements therein not
                      misleading, and the Prospectus, as amended or
                      supplemented, does not include any untrue statement of
                      material fact or omit to state a material fact necessary
                      to make the statements therein, in light of the
                      circumstances under which they were made, not misleading,
                      (B) since the effective date of the Registration
                      Statement there has occurred no event required to be set
                      forth in an amended or supplemented prospectus which has
                      not been so set forth, (C) subsequent to the respective

                      material liabilities or obligations, direct or
                      contingent, or entered into any material transactions,
                      not in the ordinary course of business, or declared or
                      paid any dividends or made any distribution of any kind
                      with respect to its capital stock, and except as
                      disclosed in the Prospectus, there has not been any
                      change in the capital stock (other than a change in the
                      number of outstanding shares of Common Stock due to the
                      issuance of shares upon the exercise of outstanding
                      options under the 1996 Stock Incentive Plan), or any
                      material change in the short-term or long-term debt, or
                      any issuance of options, warrants, convertible securities

                      Statement and the Prospectus, there is not pending, or,
                      to the knowledge of the Company, threatened or
                      contemplated, any action, suit or proceeding to which the
                      Company or any of its subsidiaries is a party before or
                      by any court or governmental agency, authority or body,

                      (j)      On each Closing Date, there shall have been
     furnished to you a certificate or certificates, dated such Closing Date
     and addressed to you, signed by each of the Selling Stockholders or any of
     such Selling Stockholder's Attorney-in-Fact to the effect that the
     representations and warranties of such Selling Stockholder contained in
     this Agreement are true and correct as if made at and as of such Closing
     Date, and that such Selling Stockholder has complied with all the
     agreements and satisfied all the conditions on such Selling Stockholder's
     part to be performed or satisfied at or prior to such Closing Date.

                      (k)      The Company shall have furnished to you and
              counsel for the
     Underwriters such additional documents, certificates and evidence as you
     or they may have reasonably requested.

                      (l)      The Common Stock shall be approved for quotation,
     subject to issuance of the Firm Shares, on the Nasdaq National Market.

                      All such opinions, certificates, letters and other
     documents will be in compliance with the provisions hereof only if they
     are satisfactory in form and substance to you and counsel for the
     Underwriters.  The Company will furnish you with such conformed copies of
     such opinions, certificates, letters and other documents as you shall
     reasonably request.

              6.      Indemnification and Contribution.
                      --------------------------------

                      (a)      The Company and each Selling Stockholder,
     severally and not jointly, agree to indemnify and hold harmless each
     Underwriter against any losses, claims, damages or liabilities, joint or
     several, to which such Underwriter may become subject, under the Act or
     otherwise (including in settlement of any litigation if such settlement is
     effected with the written consent of the Company and/or such Selling
     Stockholder, as the case may be), insofar as such losses, claims, damages
     or liabilities (or actions in respect thereof) arise out of or are based
     upon any breach of any representation, warranty or covenant of the Company
     and/or such Selling Stockholder, as the case may be, herein contained or
     any untrue statement or alleged untrue statement of a material fact

                                        - 32 -
<PAGE>






     contained in the Registration Statement, including the information deemed
     to be a part of the Registration Statement at the time of effectiveness
     pursuant to Rule 430A, if applicable, any Preliminary Prospectus, the
     Prospectus, or any amendment or supplement thereto, or arise out of or are
     based upon the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, and will reimburse each Underwriter for any legal
     or other expenses reasonably incurred by it in connection with
     investigating or defending against such loss, claim, damage, liability or
     action; provided, however, that neither the Company nor any Selling
     Stockholder shall be liable in any such case to the extent that any such
     loss, claim, damage, liability or action arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in the Registration Statement, any Preliminary Prospectus,
     the Prospectus, or any such amendment or supplement, in reliance upon and
     in conformity with written information furnished to the Company by you, or
     by any Underwriter through you, specifically for use in the preparation
     thereof.

              Notwithstanding anything in this Agreement, (i) each Selling
     Stockholder shall only be liable to the extent such untrue statement or
     omission was made in reliance on and in conformity with written
     information furnished by the Selling Stockholder in such capacity to the
     Company or the Underwriters specifically for use in the preparation of the
     Registration Statement and Prospectus; and (ii) the aggregate liability of
     any Selling Stockholder for indemnification and contribution pursuant to
     this Agreement shall not exceed an amount equal to the proceeds of the
     sale of the Securities by the Selling Stockholder after deducting all
     underwriting discounts and commissions and other costs and expenses paid
     or to be paid by such Selling Stockholder in connection with or relating
     to the transactions contemplated by this Agreement.

                      In addition to their other obligations under this Section
     6(a), the Company agrees that, as an interim measure during the pendency
     of any claim, action, investigation, inquiry or other proceeding arising
     out of or based upon any statement or omission, or any alleged statement
     or omission, described in this Section 6(a), it will reimburse each
     Underwriter on a monthly basis for all reasonable legal fees or other
     expenses incurred in connection with investigating or defending any such
     claim, action, investigation, inquiry or other proceeding, notwithstanding
     the absence of a judicial determination as to the propriety and
     enforceability of the Company's obligation to reimburse the Underwriters
     for such expenses and the possibility that such payments might later be
     held to have been improper by a court of competent jurisdiction.  To the
     extent that any such interim reimbursement payment is so held to have been
     improper, the Underwriter that received such payment shall promptly return
     it to the party or parties that made such payment, together with interest,
     compounded daily, at the Prime Rate, as defined below.  Any such interim
     reimbursement payments which are not made to an Underwriter within 30 days
     of a request for reimbursement shall bear interest determined on the basis
     of the prime rate (or other commercial lending rate for borrowers of the
     highest credit standing) announced from time to time by _______________

                                        - 33 -
<PAGE>






     (the "Prime Rate") from the date of such request.  This indemnity
     agreement shall be in addition to any liabilities which the Company may
     otherwise have.

                      (b)      Each Underwriter, severally and not jointly, will
     indemnify and hold harmless the Company and each Selling Stockholder
     against any losses, claims, damages or liabilities to which the Company
     and such Selling Stockholder may become subject, under the Act or
     otherwise (including in settlement of any litigation, if such settlement
     is effected with the written consent of such Underwriter), insofar as such
     losses, claims, damages or liabilities (or actions in respect thereof)
     arise out of or are based upon an untrue statement or alleged untrue
     statement of a material fact contained in the Registration Statement, any
     Preliminary Prospectus, the Prospectus, or any amendment or supplement
     thereto, or arise out of or are based upon the omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading, in each case to
     the extent, but only to the extent, that such untrue statement or alleged
     untrue statement or omission or alleged omission was made in the
     Registration Statement, any Preliminary Prospectus, the Prospectus, or any
     such amendment or supplement, in reliance upon and in conformity with
     written information furnished to the Company by you, or by such
     Underwriter through you, specifically for use in the preparation thereof,
     and will reimburse the Company and such Selling Stockholder for any legal
     or other expenses reasonably incurred by the Company or any such Selling
     Stockholder in connection with investigating or defending against any such
     loss, claim, damage, liability or action.

                      (c)      Promptly after receipt by an indemnified party
     under subsection (a) or (b) above of notice of the commencement of any
     action, such indemnified party shall, if a claim in respect thereof is to
     be made against the indemnifying party under such subsection, notify the
     indemnifying party in writing of the commencement thereof; but the
     omission so to notify the indemnifying party shall not relieve the
     indemnifying party from any liability that it may have to any indemnified
     party.  In case any such action shall be brought against any indemnified
     party, and it shall notify the indemnifying party of the commencement
     thereof, the indemnifying party shall be entitled to participate in, and,
     to the extent that it shall wish, jointly with any other indemnifying
     party similarly notified, to assume the defense thereof, with counsel
     satisfactory to such indemnified party, and after notice from the
     indemnifying party to such indemnified party of the indemnifying party's
     election so to assume the defense thereof, the indemnifying party shall
     not be liable to such indemnified party under such subsection for any
     legal or other expenses subsequently incurred by such indemnified party in
     connection with the defense thereof other than reasonable costs of
     investigation; provided, however, that if, in the sole judgment of the
     Representatives, it is advisable for the Underwriters to be represented as
     a group by separate counsel, the Representatives shall have the right to
     employ a single counsel to represent the Representatives and all
     Underwriters who may be subject to liability arising from any claim in
     respect of which indemnity may be sought by the Underwriters under

                                        - 34 -
<PAGE>






     subsection (a) of this Section 6, in which event the reasonable fees and
     expenses of such separate counsel shall be borne by the indemnifying party
     or parties and reimbursed to the Underwriters as incurred (in accordance
     with the provisions of the third paragraph in subsection (a) above).  An
     indemnifying party shall not be obligated under any settlement agreement
     relating to any action under this Section 6 to which it has not agreed in
     writing.

                      (d)      If the indemnification provided for in this
     Section 6 is unavailable or insufficient to hold harmless an indemnified
     party under subsection (a) or (b) above, then each indemnifying party
     shall contribute to the amount paid or payable by such indemnified party
     as a result of the losses, claims, damages or liabilities referred to in
     subsection (a) or (b) above, (i) in such proportion as is appropriate to
     reflect the relative benefits received by the Company and the Selling
     Stockholders on the one hand and the Underwriters on the other from the
     offering of the Securities or (ii) if the allocation provided by clause
     (i) above is not permitted by applicable law, in such proportion as is
     appropriate to reflect not only the relative benefits referred to in
     clause (i) above but also the relative fault of the Company and the
     Selling Stockholders on the one hand and the Underwriters on the other in
     connection with the statements or omissions that resulted in such losses,
     claims, damages or liabilities, as well as any other relevant equitable
     considerations.  The relative benefits received by the Company and the
     Selling Stockholders on the one hand and the Underwriters on the other
     shall be deemed to be in the same proportion as the total net proceeds
     from the offering (before deducting expenses) received by the Company and
     the Selling Stockholders bear to the total underwriting discounts and
     commissions received by the Underwriters, in each case as set forth in the
     table on the cover page of the Prospectus.  The relative fault shall be
     determined by reference to, among other things, whether the untrue or
     alleged untrue statement of a material fact or the omission or alleged
     omission to state a material fact relates to information supplied by the
     Company, the Selling Stockholders or the Underwriters and the parties'
     relevant intent, knowledge, access to information and opportunity to
     correct or prevent such untrue statement or omission.  The Company, the
     Selling Stockholders and the Underwriters agree that it would not be just
     and equitable if contributions pursuant to this subsection (d) were to be
     determined by pro rata allocation (even if the Underwriters were treated
     as one entity for such purpose) or by any other method of allocation which
     does not take account of the equitable considerations referred to in the
     first sentence of this subsection (d).  The amount paid by an indemnified
     party as a result of the losses, claims, damages or liabilities referred
     to in the first sentence of this subsection (d) shall be deemed to include
     any legal or other expenses reasonably incurred by such indemnified party
     in connection with investigating or defending against any action or claim
     which is the subject of this subsection (d).  Notwithstanding the
     provisions of this subsection (d), no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Securities underwritten by it and distributed to the public were
     offered to the public exceeds the amount of any damages that such
     Underwriter has otherwise been required to pay by reason of such untrue or

                                        - 35 -
<PAGE>






     alleged untrue statement or omission or alleged omission.  The aggregate
     liability of any Selling Stockholder for indemnification and contribution
     pursuant to this Agreement shall not exceed an amount equal to the
     proceeds of the sale of the Securities by the Selling Stockholder after
     deducting all underwriting discounts and commissions and other costs and
     expenses paid or to be paid by such Selling Stockholder in connection with
     or relating to the transactions contemplated by this Agreement.  No person
     guilty of fraudulent misrepresentation (within the meaning of Section
     11(f) of the Act) shall be entitled to contribution from any person who
     was not guilty of such fraudulent misrepresentation.  The Underwriters'
     obligations in this subsection (d) to contribute are several in proportion
     to their respective underwriting obligations and not joint.

                      (e)      The obligations of the Company and the Selling
     Stockholders under this Section 6 shall be in addition to any liability
     which the Company and the Selling Stockholders may otherwise have and
     shall extend, upon the same terms and conditions, to each person, if any,
     who controls any Underwriter within the meaning of the Act; and the
     obligations of the Underwriters under this Section 6 shall be in addition
     to any liability that the respective Underwriters may otherwise have and
     shall extend, upon the same terms and conditions, to each director of the
     Company (including any person who, with his consent, is named in the
     Registration Statement as about to become a director of the Company), to
     each officer of the Company who has signed the Registration Statement and
     to each person, if any, who controls the Company or any Selling
     Stockholder within the meaning of the Act.

              7.      Representations, Warranties and Agreements to Survive
     Delivery.  All representations, warranties, and agreements of the Company
     and the Selling Stockholders herein or in certificates delivered pursuant
     hereto, and the agreements of the several Underwriters and the Company and
     the Selling Stockholders contained in Section 6 hereof, shall remain
     operative and in full force and effect regardless of any investigation
     made by or on behalf of any Underwriter or any controlling person thereof,
     or the Company or any of its officers, directors, or controlling persons,
     or any Selling Stockholder or any controlling person thereof, and shall
     survive delivery of, and payment for, the Securities to and by the
     Underwriters hereunder.

              8.      Substitution of Underwriters.
                      ----------------------------

                      (a)      If any Underwriter or Underwriters shall fail to
     take up and pay for the amount of Firm Shares agreed by such Underwriter
     or Underwriters to be purchased hereunder, upon tender of such Firm Shares
     in accordance with the terms hereof, and the amount of Firm Shares not
     purchased does not aggregate more than 10% of the total amount of Firm
     Shares set forth in Schedule I hereto, the remaining Underwriters shall be
     obligated to take up and pay for (in proportion to their respective
     underwriting obligations hereunder as set forth in Schedule I hereto
     except as may otherwise be determined by you) the Firm Shares that the
     withdrawing or defaulting Underwriters agreed but failed to purchase.

                                        - 36 -
<PAGE>






                      (b)      If any Underwriter or Underwriters shall fail to
     take up and pay for the amount of Firm Shares agreed by such Underwriter
     or Underwriters to be purchased hereunder, upon tender of such Firm Shares
     in accordance with the terms hereof, and the amount of Firm Shares not
     purchased aggregates more than 10% of the total amount of Firm Shares set
     forth in Schedule I hereto, and arrangements satisfactory to you for the
     purchase of such Firm Shares by other persons are not made within 36 hours
     thereafter, this Agreement shall terminate.  In the event of any such
     termination the Company shall not be under any liability to any
     Underwriter (except to the extent provided in 4(a)(vii) and Section 6
     hereof) nor shall any Underwriter (other than an Underwriter who shall
     have failed, otherwise than for some reason permitted under this
     Agreement, to purchase the amount of Firm Shares agreed by such
     Underwriter to be purchased hereunder) be under any liability to the
     Company (except to the extent provided in Section 6 hereof).

                      If Firm Shares to which a default relates are to be
     purchased by the non-defaulting Underwriters or by any other party or
     parties, the Representatives or the Company shall have the right to
     postpone the First Closing Date for not more than seven business days in
     order that the necessary changes in the Registration Statement, Prospectus
     and any other documents, as well as any other arrangements, may be
     effected.  As used herein, the term "Underwriter" includes any person
     substituted for an Underwriter under this Section 8.

              9.      Effective Date of this Agreement and Termination.
                      ------------------------------------------------

                      (a)      This Agreement shall become effective at 10:00
     a.m., Minneapolis time, on the first full business day following the
     effective date of the Registration Statement, or at such earlier time
     after the effective time of the Registration Statement as you in your
     discretion shall first release the Securities for sale to the public;
     provided, that if the Registration Statement is effective at the time this
     Agreement is executed, this Agreement shall become effective at such time
     as you in your discretion shall first release the Securities for sale to
     the public.  For the purpose of this Section, the Securities shall be
     deemed to have been released for sale to the public upon release by you of
     the publication of a newspaper advertisement relating thereto or upon
     release by you of telexes offering the Securities for sale to securities
     dealers, whichever shall first occur.  By giving notice as hereinafter
     specified before the time this Agreement becomes effective, you, as
     Representatives of the several Underwriters, or the Company may prevent
     this Agreement from becoming effective without liability of any party to
     any other party, except that the provisions of Section 4(a)(vii),m Section
     4(b)(i) and Section 6 hereof shall at all times be effective.

     Underwriters, shall have the right to terminate this Agreement by giving
     notice as hereinafter specified at any time at or prior to the First
     Closing Date, and the option referred to in Section 3(b), if exercised,
     may be cancelled at any time prior to the Second Closing Date, if (i) the

                                        - 37 -

     Company or the Selling Stockholders shall have failed, refused or been
     unable, at or prior to such Closing Date, to perform any agreement on its
     part to be performed hereunder, (ii) any other condition of the
     Underwriters' obligations hereunder is not fulfilled, (iii) since the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, there shall have occurred any material
     adverse change or any development involving prospective material adverse
     change in or affecting the condition, financial or otherwise, of the
     Company's subsidiaries taken as a whole or the earnings, business affairs,
     management, or business prospects of the Company and its subsidiaries,
     taken as a whole whether or not arising in the ordinary course of
     business, (iv) any federal or state statute, regulation, rule or order of
     any court or other governmental authority shall have been enacted,
     published, decreed or otherwise promulgated which in your reasonable
     opinion materially and adversely affects or will materially and adversely
     affect the business or operations of the Company or any of its
     subsidiaries, (v) trading on the New York Stock Exchange or the American
     Stock Exchange shall have been wholly suspended, (vi) minimum or maximum
     prices for trading shall have been fixed, or maximum ranges for prices for
     securities shall have been required, on the New York Stock Exchange or the
     American Stock Exchange, by such Exchange or by order of the Commission or
     any other governmental authority having jurisdiction, (vii) a banking
     moratorium shall have been declared by Federal, New York, Minnesota or
     Maryland authorities, or (viii) there has occurred any material adverse
     change in the financial markets in the United States or an outbreak of
     major hostilities (or an escalation thereof) in which the United States is
     involved, a declaration of war by Congress, any other substantial national
     or international calamity or any other event or occurrence of a similar
     character shall have occurred since the execution of this Agreement that,
     in your judgment, makes it impractical or inadvisable to proceed with the
     completion of the sale of and payment for the Securities.  Any such
     termination shall be without liability of any party to any other party
     except that the provisions of Section 4(a)(viii), Section 4(b)(i) and
     Section 6 hereof shall at all times be effective.

                      (c)      If you elect to prevent this Agreement from
     becoming effective or to terminate this Agreement as provided in this
     Section, the Company and an Attorney-in-Fact, on behalf of the Selling
     Stockholders, shall be notified promptly by you by telephone or telegram,
     confirmed by letter.  If the Company elects to prevent this Agreement from
     becoming effective, you and an Attorney-in-Fact, on behalf of the Selling
     Stockholders, shall be notified by the Company by telephone or telegram,
     confirmed by letter.

              10.     Default by the Company.  If the Company shall fail at the
     First Closing Date to sell and deliver the number of Securities which it
     is obligated to sell hereunder, then this Agreement shall terminate
     without any liability on the part of any non-defaulting party.

                      No action taken pursuant to this Section shall relieve
     the Company from liability, if any, in respect of such default.

                                AMENDED AND RESTATED 

                             CERTIFICATE OF INCORPORATION

                                          OF

                       VIRTUAL OPEN NETWORK ENVIRONMENT CORP. 


              Virtual Open  Network Environment  Corp., a  corporation organized
     and existing under the  laws of the State of Delaware, hereby  certifies as
     follows:

              1.      The  name  of  the Corporation  is  Virtual  Open  Network
     Environment Corporation,  originally incorporated on October 24, 1994. 

              2.      Pursuant  to   Sections  242  and   245  of  the   General
     Corporation  Law  of the  State  of  Delaware,  this  Amended and  Restated
     Certificate of  Incorporation restates  and integrates  and further  amends
     the provision of the Certificate of Incorporation of this Corporation.

              3.      The  text  of  the Amended  and  Restated  Certificate  of
     Incorporation is  hereby restated and  amended to  read in its  entirety as
     follows:

              FIRST.  The  name  of  the Corporation  is  Virtual  Open  Network
     Environment Corporation.

              SECOND.          The registered  agent of  the Corporation  is The
     Corporation Trust  Company, Corporation Trust  Center, 1209 Orange  Street,
     Wilmington, Delaware  19801, County of New Castle.

              THIRD.  The purpose of  the Corporation is to engage in any lawful
     act or activity for  which Corporations may be organized  under the General
     Corporation Law of Delaware.

              FOURTH. The  Corporation is  authorized to  issue  two classes  of
     shares  to be  designated Common Stock  and Preferred  Stock, respectively.
     The total number  of shares of  stock the Corporation shall  have authority
     to   issue  is   seventy  million  (70,000,000)   shares:    fifty  million
     (50,000,000) shares  of Common Stock  with par value  of $0.001  per share,
     and twenty  million (20,000,000) shares  of Preferred Stock  with par value
     of $0.001 per share.

              The Corporation  shall from time  to time in  accordance with  the
     laws of the State of Delaware increase the authorized amount of its  Common
     Stock  if at  any  time the  number  of shares  of  Common Stock  remaining
     unissued  and available  for  issuance shall  not  be sufficient  to permit
     conversion of the Preferred Stock.


              FIFTH.  The  Board   of  Directors   is  authorized,  subject   to
     limitations prescribed  by law  and the  provisions of  Article Fourth,  to
     provide, by resolution  or resolutions and by filing a certificate pursuant
<PAGE>






     to  the  applicable law  of  the State  of  Delaware, for  the  issuance of
     additional classes  of stock  and one or  more series  of stock within  any
     such class, and  the number of  shares to be  included in such classes  and
     series,  which classes  and series  may have  such voting  powers, full  or
     limited, or no  voting powers,  and such powers,  designations, preferences
     and  relative,  participating,  optional  or  other   special  rights,  and
     qualifications,  limitations or restrictions thereof as  shall be stated in
     such resolution or resolutions and certificate.

              SIXTH.  The  names  of  the  directors  of   the  Corporation  are
     James F.  Chen, Charles  Chen,  Maxine Loh  and H.H.  Cheng.   The  mailing
     address  for each  is  1803 Research  Boulevard,  Suite 305,  Rockville, MD
     20850.

              SEVENTH.         The Corporation is to have perpetual existence.

              EIGHTH. Elections  of directors  need  not  be by  written  ballot
     except and to the extent provided in the bylaws of the Corporation.

              (a)     The  number  of directors  constituting  the  entire Board
     shall be  not less  than three nor  more than seven  as fixed from  time to
     time by vote of  a majority  of the entire  Board, provided, however,  that
     the number of directors shall not be reduced  so as to shorten the term  of
     any director at the time in office.  

              (b)     The  Board  of  Directors  shall  be  divided  into  three
     classes, as nearly equal in numbers as  the then total number of  directors
     constituting the entire Board permits with the term of office of one  class
     expiring  each year.   At  the annual    meeting of  stockholders in  1996,
     directors of  the first class shall  be elected to  hold office for  a term
     expiring at the  next succeeding annual  meeting, directors  of the  second
     class shall  be elected to  hold office for  a term expiring  at the second
     succeeding  annual  meeting and  directors  of  the  third  class shall  be
     elected to hold  office for a term expiring  at the third succeeding annual
     meeting.   Any vacancies in the Board of Directors  for any reason, and any
     directorships resulting  from  any increase  in  the number  of  directors,
     shall be  filled by the  Board of Directors,  acting by  a majority of  the
     directors  then in office,  although less than a  quorum, and any directors
     so  chosen shall hold office until the next election of the class for which
     such directors shall have been  chosen and until their successors  shall be
     elected and  qualified.    Notwithstanding  the foregoing,  and  except  as
     otherwise required by law, whenever the holders  of any one or more  series
     of Preferred Stock  shall have the right, voting  separately as a class, to
     elect one or more  directors of the Corporation, the terms of  the director
     or directors elected by  such holders shall  expire at the next  succeeding
     annual meeting of stockholders.  Subject  to the foregoing, at each  annual
     meeting of  stockholders the  successors to  the class  of directors  whose
     term shall then expire shall be elected  to hold office for a term expiring
     at the third succeeding annual meeting.

              (c)     Notwithstanding any  other provisions  of this Certificate
     of Incorporation or  the bylaws of the Corporation (and notwithstanding the

                                        - 2 -
<PAGE>






     fact  that some lesser percentage may be specified by law, this Certificate
     of  Incorporation or the  bylaws of the  Corporation), any  director or the
     entire Board of  Directors of the Corporation  may be removed at  any time,
     but only  for cause and only by the  affirmative vote of the holders of 75%
     or more  of  the outstanding  shares of  capital stock  of the  Corporation
     entitled to vote  generally in the  election of  directors (considered  for
     this purpose as one  class) cast  at a meeting  of the stockholders  called
     for that purpose.  

              NINTH.  The  Corporation 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
     Corporation who was or is made a 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  Corporation,  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.

              A  director of the  Corporation shall not be  personally liable to
     the Corporation  or its  stockholders for  monetary damages  for breach  of
     fiduciary duty as  a director; provided, however, that this provision shall
     not  eliminate or limit the liability of a director to the extent that such
     elimination or  limitation  of liability  is  expressly prohibited  by  the
     General Corporation Law of the State  of Delaware as in effect at the  time
     of the alleged breach of fiduciary duty by such director.

              Any  repeal  or   modification  of  this  Article   Ninth  by  the
     stockholders of the  Corporation shall not  adversely affect  any right  or
     protection existing at  the time  of such repeal  or modification to  which
     any person may be entitled under this Article Ninth.  The rights  conferred
     by this  Article Ninth shall not be exclusive of  any other right which the
     Corporation  may  now or  hereafter  grant,  or  any  person  may  have  or
     hereafter acquire,  under any  statute,  provision of  this Certificate  of
     Incorporation,  Bylaw, agreement,  vote  of stockholders  or  disinterested
     directors or otherwise.   The rights conferred by  this Article Ninth shall
     continue as to any  person who has  ceased to be  a director or officer  of
     the Corporation and shall inure to the benefit  of the heirs, executors and
     administrators of such person.

              For  the purposes  of  this  Article Ninth,  the  term "authorized
     representative" shall  mean a director,  officer, employee or  agent of the
     Corporation or  of  any  subsidiary  of  the  Corporation,  or  a  trustee,
     custodian,  administrator,  committeeman  or  fiduciary  of   any  employee
     benefit plan  established  and maintained  by  the  Corporation or  by  any
     subsidiary of the  Corporation; or a person  who is or was  serving another
     corporation, partnership,  joint venture, trust or  other enterprise in any
     of the  foregoing  capacities  at  the  specific  written  request  of  the
     Corporation.

              The affirmative  vote  of  the holders  of  at least  75%  of  the
     outstanding shares  of  the capital  stock  of  the Corporation,  given  in
     person or by proxy, at  a meeting called for the purpose  of voting thereon
     shall be required to amend or repeal this Article Ninth.

              TENTH.  All  corporate  powers and  authority  of  the Corporation
     shall be  vested in  and  exercised by  the Board  of Directors  except  as
     otherwise provided  by statute,  this Certificate  of Incorporation or  the
     bylaws of the  Corporation.  In furtherance  and not in limitation  of that
     power, the Board  of Directors shall have the  power to make, adopt, alter,
     amend and repeal from  time to time the bylaws of the  Corporation, subject
     to the right of the stockholders entitled  to vote with respect thereto  to
     adopt,  alter, amend  and repeal  bylaws made  by  the Board  of Directors;
     provided, however, that the bylaws  shall not be adopted,  altered, amended
     or repealed by  the stockholders of the  Corporation except by the  vote of
     the  holders  of not  less  than 75%  of  the outstanding  shares  of stock
     entitled to vote  upon the election of  directors.  The Board  of Directors
     also shall have the  authority to determine whether and to what extent, and
     at what  times and places,  and under what  conditions and  regulations the
     accounts and books of  the Corporation (other than the stock  ledger) shall
     be  open  to inspection  by stockholders.   No  stockholder shall  have any
     right to  inspect any account, book, or  document of the Corporation except
     to the extent permitted by statute or the bylaws.  

              ELEVENTH.   The Corporation  reserves the  right to amend,  alter,
     change  or   repeal  any  provision   contained  in  this  Certificate   of
     Incorporation, in the  manner now or  hereafter prescribed  by statue,  and
     all rights  conferred upon  the  officers, directors  and stockholders  are
     granted subject to this reservation.

              TWELFTH:

                      (a)    Vote Required  for  Certain Business  Combinations.
              The affirmative  vote of  not  less than  75% of  the  outstanding
              shares  of  "Voting  Stock"   (as  hereinafter  defined)  held  by
              stockholders  other than  an "Interested  Person"  (as hereinafter
              defined) shall  be required for the  approval or authorization  of
              any  "Business  Combination"   (as  hereinafter  defined)  of  the
              Corporation  with any  Interested Person; provided,  however, that
              the 75% voting requirement shall not be applicable if:

                      recent  fiscal   year  ended   prior  to   the  date   the
                      termination is being made.

                               (8)    Other  Consideration.    The  term  "Other
                      Consideration" includes, without limitation, common  stock
                      or other capital stock of the  Corporation retained by its
                      existing stockholders  other  than Interested  Persons  or
                      other parties  to such Business  Combination in the  event
                      of a Business  Combination in which the Corporation is the
                      surviving Corporation.

                      (d)     Fiduciary  Obligations   of  Interested   Persons.
              Nothing  contained in  this Article TWELFTH shall  be construed to
              relieve  any  Interested  Person  from  any  fiduciary  obligation
              imposed by law.

                      (e)   Determinations by the  Disinterested Directors.   In
              making  any determinations,  the  Disinterested Directors  may, at
              the  expense of  the Corporation,  engage such  persons, including
              investment banking firms and  the independent accountants who have
              reported  on  the    most  recent  financial   statements  of  the
              Corporation, and utilize employees  and agents of the Corporation,
              who  will, in the  judgment of the Disinterested  Directors, be of
              assistance to  the Disinterested  Directors.   Any  determinations
              made by the  Disinterested Directors, acting in good faith  on the
              basis of  such information and assistance  as was then  reasonably
              available  for such purposes, shall be conclusive and binding upon
              the  Corporation  and its  stockholders, including  any Interested
              Person.

                      (f)   Amendments  to  the  Article.   Notwithstanding  any
              other  provision  of  this  Certificate  of Incorporation  or  the
              bylaws  of the  Corporation and  notwithstanding that  absent this
              provision, a lesser percentage  may be sufficient under applicable
              law,  the affirmative  vote of  not less  than  75% of  the Voting
              Stock held by  stockholders other than an Interested  Person shall
              be required to amend,  repeal or adopt any provisions inconsistent
              with this Article TWELFTH.

                                          OF

                    VIRTUAL OPEN NETWORK ENVIRONMENT CORPORATION



                                     ARTICLE I.
                                     ----------

                               MEETINGS OF SHAREHOLDERS
                               ------------------------

              Section 1.1      Places of Meetings. All meetings of the share-
     holders shall be held at such place, either within or without the State of
     Delaware, as from time to time may be fixed by the Board of Directors.

              Section 1.2      Annual Meeting. The annual meeting of the
     shareholders for the election of Directors and transaction of such other
     business as may come before the meeting shall be held at such date and
     time as shall be designated from time to time by the Board of Directors
     and stated in the notice of the meeting.  Unless otherwise designated by
     the Board of Directors, the annual meeting shall be held on the first
     Friday of the month of June.

              Section 1.3      Special Meetings.  A special meeting of the
     shareholders for any purpose or purposes may be called at any time by the
     President or the Chairman of the Board or a majority of the Board of
     Directors as prescribed by statute.

              Section 1.4      Notice of Meetings.  Written notice of all
     meetings shall be given, stating the place, date, and hour of the meeting
     and stating the place within the city or other municipality or community
     at which the list of stockholders of the Corporation may be examined.  The
     notice of a meeting shall in all instances state the purpose or purposes
     for which the meeting is called.  If any action is proposed to be taken
     which would, if taken, entitle stockholders to receive payment for their
     shares of stock, the notice shall include a statement of that purpose and
     to that effect.  Except as otherwise provided by the General Corporation
     Law of the State of Delaware, a copy of the notice of any meeting shall be
     given, personally or by telex, telefax, telephone, telegraph or postal
     mail, not less than ten days nor more than sixty days before the date of
     the meeting, unless the lapse of the prescribed period of time shall have
     been waived, and directed to each stockholder at his record address or at
     such other address which he/she may have furnished by request in writing
     to the Secretary of the Corporation. Notice by mail shall be deemed to be
     given when deposited, with postage thereon prepaid, in the U.S. mail.  If
     a meeting is adjourned to another time, not more than thirty days hence,
     and/or to another place, and if an announcement of the adjourned time
     and/or place is made at the meeting, it shall not be necessary to give
     notice of the adjourned meeting. Notice need not be given to any
     stockholder who submits a written waiver of notice by him/her before or
     after the time stated therein.  Attendance of a person at a meeting of
<PAGE>






     stockholders shall constitute a waiver of notice of such meeting, except
     when the stockholder attends a meeting for the express purpose of
     objecting, at the beginning of the meeting, to the transaction of any
     business because the meeting is not lawfully called or convened. Neither
     the business to be transacted at, nor the purpose of, any meeting of the
     stockholders need be specified in any written waiver of notice.

              Section 1.5      Quorum.  Any number of shareholders together
     holding at least a majority of the outstanding shares of stock entitled to
     vote with respect to the business to be transacted, who shall be present
     in person or represented by proxy at any meeting duly called, shall
     constitute a quorum for the transaction of business.  If less than quorum
     shall be in attendance at the time for which a meeting shall have been
     called, the meeting may be adjourned from time to time by a majority of
     the shareholders present or represented by proxy without notice other than
     by announcement at the meeting.

              Section 1.6      Proxies and Voting.  Each shareholder shall, at
     every meeting of the shareholders, be entitled to one vote in person or by
     proxy for each share of capital stock having voting power held by such
     shareholder as of the record date set for the meeting.  All action
     requiring the approval of the shareholders shall be authorized by a
     majority of the votes cast except where the General Corporation Laws of
     the State of Delaware prescribes a different percentage of votes and/or a
     different exercise of voting power.  A proxy shall be authorized by an
     instrument in writing, dated and signed by the shareholder entitled to
     vote or his duly authorized attorney-in-fact.  The original or a facsimile
     of the proxy shall be filed with the Secretary.  All voting may be taken
     either by voice vote or by written ballots, except where otherwise
     required by law.  No proxy shall be voted after three years from its date,
     unless the proxy provides for a longer period.

              Section 1.7      Inspectors and Judges.  The person presiding at
     any meeting of shareholders may, but need not, appoint one or more
     inspectors or judges.  Each inspector or judge, if any, before entering
     upon the discharge of his/her duties, shall take and sign an oath
     faithfully to execute the duties of inspector or judge at such meeting
     with strict impartiality and according to the best of his/her ability. 
     The inspectors or judges, if any, shall determine the number of shares of
     stock outstanding and the voting power of each, the shares of stock
     represented at the meeting, the existence of a quorum, the validity and
     effect of proxies, and shall receive votes, ballots or consents, hear and
     determine all challenges and questions arising in connection with the
     right to vote, count and tabulate all votes, ballots or consents,
     determine the result, and do such acts as are proper to conduct the
     election or vote with fairness to all shareholders.  On request of the
     person presiding at the meeting, the inspector or inspectors or judge or
     judges, if any, shall make a report in writing of any challenge, question
     or matter determined by him/her or them and execute a certificate of any
     fact found by him/her or them.

              Section 1.8      Written Consent.  Any action required or
     permitted by law to be taken at a shareholders' meeting may be taken
     without a meeting, without action by the Board of Directors, without prior
     notice, and without a vote, if consents in writing setting forth the
     action are signed by all shareholders entitled to vote upon the action. 
     Written consents, in order to be valid, must be delivered by postal mail
     or telefax to the Secretary of the Corporation for inclusion in the
     minutes or filing in the corporate minutes.  Every written consent shall
     bear the signature of each shareholder who makes the consent and the date
     upon which the consent was signed.

     filled by a majority of the Directors then in office, although less than a
     quorum, or by a sole remaining Director.  A Director chosen to fill a
     vacancy shall have the same term as that Director's predecessor.  

              Section 2.6      Removal and Resignation of Directors.  Directors

            INDEMNIFICATION OF DIRECTORS, OFFICERS, AGENTS, AND EMPLOYEES
            -------------------------------------------------------------

              Section 6.1      Right to Indemnification.  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 Corporation shall be
     indemnified and held harmless by the Corporation to the fullest extent
     authorized by the General Corporation Law of the State of Delaware, as the

                                        - 8 -

     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 above, no Director shall be indemnified nor held
     harmless in violation of the provisions set forth in the Certificate of
     Incorporation; and no Director, officer, agent, or employee shall be
     indemnified nor held harmless by the Corporation unless:

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

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

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

              Section 6.2      Right to Advancement of Expenses.  The right to
     indemnification conferred in Section 6.1 of this Article shall include the
     right to be paid by the Corporation the expenses incurred in defending any
     such proceeding in advance of its final disposition; provided, however,
     that such an advancement of expenses shall be made only upon delivery to
     the Corporation of (1) a statement of his/her good faith belief that
     he/she has met the standard of conduct described in Section 6.1; and (2)
     an undertaking by or on behalf of the indemnitee, to repay all amounts so
     advanced if it shall ultimately be determined by final judicial decision
     that he/she is not entitled to be indemnified for such expenses.

              Section 6.3      Determination and Authorization to Indemnify. 
     The Corporation may not indemnify a Director under Section 6.1 unless
     authorized after a determination has been made that indemnification of the
     Director is permissible in the circumstances because he/she has met the
     standard of conduct in Section 6.1.  This determination shall be made by
     the Board of Directors by a majority vote of a quorum consisting of
     Directors not at the time parties to the proceeding.

              Section 6.4      Non-Exclusivity of Rights.  The rights to
     indemnification and to the advancement of expenses conferred in this
     Article shall not be exclusive of any other right which any person may
     have or hereafter acquire under any statute, the Corporation's Certificate
     of Incorporation, agreement, vote of shareholders or disinterested
     Directors, or otherwise.

              Section 6.5      Insurance.  The Corporation may maintain
     insurance, at its expense, to protect itself and any Director, officer,
     employee or agent of the Corporation against any expense, liability or
     loss.

              Section 7.1      Issuance.  The Corporation may issue shares of
     capital stock of any class or series now or hereafter authorized in the
     Certificate of Incorporation, in accordance with the authority granted by
     a Board of Directors resolution.

              Section 7.2.     Stock Certificates.  Each shareholder shall be
     entitled to a certificate signed in the name of the Corporation by the
     President and by the Secretary, and affixed with the seal of the
     Corporation.  The Treasurer may sign in lieu of the Secretary.  Signatures
     on the certificate may be facsimiles. In case any officer who has signed
     or whose facsimile signature has been placed upon such certificate shall
     have ceased to be such officer before such certificate is issued, it may
     be issued by the Corporation with the same effect as if he/she were such
     officer at the date of its issue.

              Section 7.3      Transfer of Stock.  Transfer of stock may be made
     only on the transfer ledger of the Corporation kept at an office of the
     Corporation or in the possession of the Secretary or the corporate
     transfer agent.  Upon surrender to the Corporation or the transfer agent
     of the Corporation of a certificate for shares duly endorsed or
     accompanied by proper evidence of succession, assignation or authority to
     transfer, it shall be the duty of the Corporation to issue a new
     certificate to the person entitled thereto, cancel the old certificate and
     record the transaction upon its books.

              Section 7.4      Record Date.  In order that the Corporation may
     determine the shareholders entitled to notice of or to vote at any meeting
     of shareholders, or to receive payment of any dividend or other
     distribution or allotment of any rights, or to exercise any rights in
     respect of any change, conversion or exchange of stock, the Board of
     Directors may fix a record date.  Such record date shall not precede the
     date on which the Board of Directors' resolution fixing the record date is
     adopted, and shall not be more than 70 days prior to the meeting or such
     other action as above described.

              If no record date is fixed by the Board of Directors for
     determination of who is entitled to vote or receive notice of a
     shareholders' meeting, the record date shall be at the close of business
     on the day preceding the day on which notice is given; or if notice is
     waived, at the close of business on the day preceding the day on which the
     meeting is held.  If no record date is set for determining shareholders
     entitled to receive a dividend or other distribution or allotment of
     rights or to exercise any rights in respect to any change, conversion or
     exchange of stock, the record date shall be at the close of business on


                                        - 10 -
<PAGE>






     the day on which the Board of Directors adopts a resolution relating
     thereto.

              When a determination of shareholders entitled to vote at any
     meeting of shareholders has been made as provided in this Section, such
     determination shall apply to any adjournment thereof unless the Board of
     Directors fixes a new record date, which it shall do if the meeting is
     adjourned to a date more than 120 days after the date fixed for the
     original meeting.

              In order that the Corporation may determine the shareholders
     entitled to consent in writing to corporate action taken without a
     meeting, the Board of Directors may fix a record date, which shall not
     precede and shall not be more than ten days after the date on which the
     resolution fixing the record date is adopted.  If no record date has been
     fixed by the Board of Directors, and the Board of Directors is not
     required by law to take some action prior to the action for which written
     consent is sought, the record date shall be the first date on which a
     signed written consent is properly delivered to the Corporation.  If no
     record date had been fixed by the Board of Directors and the Board of
     Directors is required by law to take some action prior to the action for
     which written consent is sought, the record date shall be the close of
     business on the day on which the Board of Directors adopts a resolution
     taking such prior action.  

              Section 7.5      Replacement Certificates.  New stock certificates
     may be issued to replace certificates lost, stolen, destroyed, or
     mutilated, upon such terms and conditions, including proof of loss or
     destruction and the giving of a satisfactory bond of indemnity, as the
     Board of Directors may from time to time determine.

              Section 7.6      Holders of Record.  The Corporation shall be
     entitled to treat the holder of record of any share or shares of capital
     stock as the holder and owner in fact thereof for all purposes and shall
     not be bound to recognize any equitable or other claim of right, title, or
     interest in such share or shares on the part of any other person, whether
     or not the Corporation shall have express or other notice thereof, except
     as otherwise provided by law. 

              Section 7.7      Regulations.  The issue, transfer, conversion and
     registration of certificates of stock shall be governed by such other
     regulations as the Board of Directors may establish.

     arranged by voting group and within each voting group by class or series
     of shares, with the address of each and the number of shares held by each,

     on file at the principal business office of the Corporation and shall be
     subject to inspection by any shareholder at any time during usual business
     hours.  Such list shall also be produced and kept open at the time and
     place of the meeting and shall be subject to the inspection of any
     shareholder during the whole time of the meeting.  The original share
     transfer book, or a duplicate thereof, shall be prima facie evidence as to
     who are the shareholders entitled to examine such list or share transfer
     book or to vote at any meeting of the shareholders.

     the Corporation may be declared by the Board of Directors at any regular
     or special meeting, pursuant to law.  Dividends may be paid in cash, in
     property, or in shares of capital stock.  Before payment of any dividend,
     there may be set aside out of any funds of the Corporation available for
     dividends such sum or sums as the Board of Directors in its absolute
     discretion, from time to time, believes is proper as a reserve fund to
     meet contingencies, or equalize dividends, or for such other purposes as
     the Board of Directors determines is conducive to the interests of the
     Corporation.  The Board of Directors may at any time modify or abolish any
     such reserve fund. 

              Section 9.2      Annual Statement.  The Board of Directors shall
     present at each annual meeting, and at any special meeting of the
     shareholders when called for by vote of the shareholders, a full and clear
     statement of the business and condition of the Corporation.  

              Section 9.3      Fiscal Year.  The fiscal year of the Corporation
     shall be fixed by resolution of the Board of Directors from time to time.

              Section 9.4      Checks.  All checks or demands for money and
     notes of the Corporation shall be signed by such officer or officers or
     such other person or persons as the Board of Directors may from time to
     time designate.

              Section 9.5      Seal.  The Corporate seal shall have inscribed
     thereon the name of the Corporation, the year of its organization and the
     words "Corporate Seal, Delaware."  The seal may be used by causing it or a
     facsimile thereof to be impressed or affixed or in any manner reproduced.

     amended, repealed, or replaced by new Bylaws by the affirmative vote of a

     following resolution creating a series of 1,183,402 shares of convertible
     preferred stock designated as Series A Convertible Preferred Stock;

              That, pursuant to the authority vested in the Board of Directors
     of the Corporation in accordance with the provisions of its Certificate of
     Incorporation, a series of preferred stock of the Corporation be, and it
     hereby is, created, and that the designation and amount thereof and the
     powers, preferences, and relative, optional, and other special rights of
     the shares of such series, and the qualifications, limitations, or
     restrictions thereof are as follows:

              Section 1.  DESIGNATION AND AMOUNT.  The shares of such series
     shall be designated as "Series A Convertible Preferred Stock" and the
     number of shares constituting such series shall be 1,183,402.

              Section 2.  DIVIDENDS AND DISTRIBUTIONS.  Dividends upon the
     shares of Series A Convertible Preferred Stock may be declared by the
     Board of Directors at any time and may be paid in cash, in property, or in
     shares of Series A Convertible Preferred Stock.  The holders of shares of
     Series A Convertible Preferred Stock are entitled to share ratably in
     dividends with holders of any other series of preferred stock of the
     Corporation now existing or hereafter created, but shall receive no
     preference in dividends declared.  The Corporation will not pay dividends
     on Common Stock as long as Series A Convertible Preferred Stock is
     outstanding.

              Section 3.  VOTING RIGHTS.  In addition to any other voting
     rights required by law, the holders of shares of Series A Convertible
     Preferred Stock shall have the following voting rights:

     entitle the holder thereof to vote on all matters submitted to a vote of
     the stockholders of the Corporation, and the holders of Series A
     Convertible Preferred Stock shall vote as a class on matters affecting

     authorized by a majority vote of such holders.  

              (b)     Except as set forth herein, holders of Series A
     Convertible Preferred Stock shall have no special voting rights and their
     consent shall not be required (except to the extent they are entitled to
     vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

              Section 4.  REACQUIRED SHARES.  Any shares of Series A
     Convertible Preferred Stock purchased or otherwise acquired by the
     Corporation in any manner whatsoever shall be retired and canceled

     cancellation, become authorized but unissued shares of Preferred Stock and
     may be reissued as part of a new series of Preferred Stock to be created
     by resolution or resolutions of the Board of Directors.  The Corporation
     will not repurchase Common Stock as long as Series A Convertible Preferred
     Stock is outstanding without the approval of the holders of the Series A
     Convertible Preferred Stock voting as a class.

              Section 5.  LIQUIDATION PREFERENCE.  In the event of any
     voluntary or involuntary liquidation, sale, or winding up of the
     Corporation, the holders of Series A Convertible Preferred Stock shall be
     entitled to receive in preference to holders of Common Stock an amount
     equal to the purchase price per share of the Series A Convertible
     Preferred Stock plus any accrued but unpaid dividends.  Any remaining
     proceeds shall be allocated between Common and Preferred Shareholders on a
     pro-rata basis, treating the shares of Series A Convertible Preferred
     Stock on an as-if converted basis.

              Section 6.  CONVERSION.  Shares of Series A Convertible Preferred
     Stock may at any time be converted into shares of Common Stock, on a one
     for one basis, provided that such shares of Series A Convertible Stock
     have not been previously converted pursuant to Section 7 below.

              Section 7.  MANDATORY CONVERSION.  Shares of Series A Convertible
     Preferred Stock will be subject to a mandatory conversion by the
     Corporation on ten (10) days written notice in the event of an initial
     public offering of shares of the Corporation's Common Stock in which over
     $15 million is raised and the offering price per share is at least 1.75
     times the initial conversion price per share of the Series A Convertible
     Preferred Stock.

              Section 8.  CONVERSION RATIO ADJUSTMENT.  The conversion ratio
     provided in Section 6 shall be subject to adjustment under the
     circumstances and in the manner as described below:

              (a)     In the event that the Corporation effects an initial
     public offering prior to March 31, 1997 at a price less than $5.25 per
     share, the conversion ratio shall be adjusted by multiplying the
     subscription price of the Series A Convertible Preferred Stock times a
     factor of 1.75, and dividing the product by the midpoint of the filing
<PAGE>






     range contained in the final pre-effective amendment to the registration
     statement for the initial public offering, so that if the subscription
     price is $3.00 per share and the midpoint of the filing range is $4.50 per
     share, the conversion ratio would be determined by multiplying $3.00 x
     1.75, and dividing the product by $4.50 to reach a conversion ratio of
     1.1667 shares of Common Stock for each converted share of Series A
     Convertible Preferred Stock;

              (b)     In the event that the Corporation effects an initial
     public offering during the period from April 1, 1997 until March 31, 1998
     at a price less than $6.00 per share, the conversion ratio shall be
     adjusted by multiplying the subscription price of the Series A Convertible
     Preferred Stock times a factor of 2.00, and dividing the product by the
     midpoint of the filing range contained in the final pre-effective
     amendment to the registration statement for the initial public offering,
     so that if the subscription price is $3.00 per share and the midpoint of
     the filing range is $4.50 per share, the conversion ratio would be
     determined by multiplying $3.00 x 2.00, and dividing the product by $4.50
     to reach a conversion ratio of 1.333 shares of Common Stock for each
     converted share of Series A Convertible Preferred Stock;

              (c)     In the event that the Corporation effects an initial
     public offering after March 31, 1998 at a price less than $9.00 per share,
     the conversion ratio shall be adjusted by multiplying the subscription
     price of the Series A Convertible Preferred Stock times a factor of 3.00,
     and dividing the product by the midpoint of the filing range contained in
     the final pre-effective amendment to the registration statement for the
     initial public offering, so that if the subscription price is $3.00 per
     share and the midpoint of the filing range is $4.50 per share, the
     conversion ratio would be determined by multiplying $3.00 x 3.00, and
     dividing the product by $4.50 to reach a conversion ratio of 2.00 shares
     of Common Stock for each converted share of Series A Convertible Preferred
     Stock. 

              Section 9.  CONSOLIDATION, MERGER, ETC.  In case the Corporation
     shall enter into any consolidation, merger, combination, or other
     transaction in which the shares of Common Stock are exchanged for or
     changed into other stock or securities, cash, and/or any other property,
     then in any such case the shares of Series A Convertible Preferred Stock
     shall at the same time be similarly exchanged or changed in an amount per
     share (subject to the provision for adjustment hereinafter set forth)
     equal to the amount of stock, securities, cash, and/or any other property
     (payable in kind), as the case may be, into which or for which each share
     of Common Stock is changed or exchanged.  In the event the Corporation
     shall at any time after the date hereof (a) declare any dividend on Common
     Stock payable in shares of Common Stock, (b) subdivide the outstanding
     shares of Common Stock, or (c) combine the outstanding shares of Common
     Stock into a smaller number of shares, then in each such case the amount
     set forth in the preceding sentence with respect to the exchange or change
     of shares of Series A Convertible Preferred Stock shall be adjusted by
     multiplying such amount by a fraction, the numerator of which is the
     number of shares of Common Stock outstanding immediately after such event
     and the denominator of which is the number of shares of Common Stock that
     were outstanding immediately prior to such event.

              Section 10.  REDEMPTION.  The shares of Series A Convertible
     Preferred Stock, on or before December 31, 2001, will be subject to
     redemption at the option of the holder, if not previously converted, at
     the earlier of a dissolution, winding up, or sale or merger wherein a
     "change of control" occurs ("Liquidity Events").  A change of control will
     occur: a) upon the sale or transfer of substantially all the assets of the
     Corporation by sale, merger or otherwise, or b) if any "person" (as such
     term is used in Sections 13(d) or 14(d) of the 1934 Act) is or becomes the
     beneficial owner, directly or indirectly, of securities of the Corporation
     representing 50% or more of the combined voting power of the then-existing
     outstanding securities of the Corporation.  If no Liquidity Event occurs
     on or before December 31, 2001, shares of Series A Convertible Preferred
     Stock will be subject to redemption, at the option of the holder, in equal
     amounts effective as of December 31, 2001, December 31, 2002, and December
     31, 2003.  The redemption price will equal the initial purchase price and
     there shall be no interest or premium paid.  

              Section 11.  AMENDMENT.  The Certificate of Incorporation of the
     Corporation shall not be further amended in any manner that would
     materially alter or change the powers, preferences, or special rights of
     the Series A Convertible Preferred Stock so as to affect them adversely
     without the affirmative vote of the holders of a majority of the
     outstanding shares of Series A Convertible Preferred Stock, voting
     separately as a class.

              IN WITNESS WHEREOF, we have executed and subscribed this
     Certificate and do affirm the foregoing as true under the penalties of
     perjury this 4th day of April, 1996.

                                VOTING TRUST AGREEMENT


              THIS  AGREEMENT, is  intended to  memorialize and  consolidate the
     terms of  prior  understandings  of  the  parties  and  is  therefore  made
     effective as of  the 1st day of  January, 1996, by  and between H.H.  Cheng
     (hereinafter referred  to as  "Stockholder"), and  James F. Chen,  Trustee,
     and his  successor and  successors in the  Trust, (hereinafter collectively
     referred to as "Voting Trustee"):

              1.      Stockholder  has   assigned  and   transferred  to  Voting
     Trustee  the  number  of   shares  of  Virtual  Open  Network   Environment
     Corporation (the Corporation)  set opposite  his or  her signature  hereto,
     for the  purpose of  vesting in  Voting Trustee,  as Trustee  of an  active
     trust, the right to vote  thereon and act in respect thereof,  for a period
     of 1  year from the  date hereof, or  initial public offering whichever  is
     first,  subject  to  earlier  termination  by the  Trustee  as  hereinafter
     provided.

              2.      Voting Trustee  shall cause  to be  issued, in respect  of
     the stock  of the Corporation held by him, pursuant  to the terms hereof, a
     voting trust  certificate  in a  form  acceptable to  the parties  and  the
     Corporation (hereinafter referred to as the "voting trust certificate"):

              3.      In  the  event  that  Voting  Trustee  shall  receive  any
     additional stock certificates  of Corporation by way of dividend upon stock
     held by  it under  this  Agreement, Voting  Trustee shall  hold such  stock
     certificates likewise subject  to the terms  of this  Agreement, and  shall
     issue voting  trust certificates  representing such  stock certificates  to
     the  respective  registered holder  of  the then  outstanding  voting trust
     certificate entitled to such dividend.

              4.      Voting  Trustee  shall execute  any  and all  of  the said
     voting trust certificates, and no  voting trust certificate shall  be valid
     unless duly signed by Voting  Trustee.  Each voting trust certificate shall
     be transferable on  the voting trust  certificate books  of Voting  Trustee
     (which shall be  kept for that purpose  at the office of the  said Trustee)
     by the registered  holder thereof, either  in person or by  duly authorized
     attorney,  upon  the surrender  of such  voting trust  certificate properly
     endorsed for transfer.   Until so transferred, the Voting Trustee may treat
     the registered holder  of voting trust  certificates as  owner thereof  for
     all purposes, except  that the delivery of stock certificates hereunder and
     certain  payments hereunder,  as hereinafter  provided, shall  not be  made
     without surrender of such voting trust certificates.

              5.      Until  the termination  of this  Agreement each registered
     holder of a voting trust certificate shall  be entitled to receive promptly
     from  Voting Trustee payments equal to  the amount of dividends (other than
     dividends  represented  by  capital  stock  of  the Corporation)  or  other
     distributions  if any,  collected  by Voting  Trustees  upon the  number of
     shares of stock of the Corporation standing in the name of such  registered
     holder, and  any payment representing  the amount received upon  redemption
     or sale of  any common stock, represented  by the voting trust  certificate
<PAGE>






     or  certificates held by him, subject, however, to the terms and conditions
     of  this  Agreement.    Those   registered  as  holders  of   voting  trust
     certificates on  the dates  fixed as record  dates by  the Corporation  for
     dividends  and for  the  allotment  of rights  shall  be entitled  to  such
     payments and to any rights to the benefit of which holders of voting  trust
     certificates may be  entitled under this  Agreement.   Voting  Trustee may,
     in  his discretion, from time  to time, close  the voting trust certificate
     books against transfers  of voting trust  certificates for  the purpose  of
     determining  the voting trust certificate  holder entitled to such payments
     or to  such rights,  or for  the purpose  of determining  the voting  trust
     certificate holder  entitled to vote  at any meeting  thereof or to do  any
     thing or act to be done or performed by said holders.

              6.      This  Agreement   shall  terminate   one  year   from  its
     effective date  or upon initial  public offering if  earlier without notice
     by or  action of the Voting  Trustee; but, at  any earlier time,  it may be
     terminated  by   the  written  action   of  the  Voting   Trustee,  in  his
     uncontrolled  discretion,  by  signing  a declaration  to  that  effect and
     sending a  copy of  the  same to  each registered  holder of  voting  trust
     certificates  issued hereunder.    Upon termination  of  this Agreement  as
     above specified, Voting  Trustee, in exchange  for, or  upon surrender  of,
     any  voting trust  certificate then outstanding,  shall, in accordance with
     the terms  hereof, and  out of  the stock  held by  him hereunder,  deliver
     proper certificates  of stock of the  Corporation to the  holders of voting
     trust certificates  and thereupon all  liability of Voting  Trustee, or his
     successors, or  successor, or  of any  of them,  for the  delivery of  said
     stock certificates  shall cease  and terminate.   Voting  Trustee may  call
     upon and  require the  holders of  voting trust  certificates to  surrender
     them in  exchange for  certificates of  stock of  the number  of shares  to
     which they are entitled hereunder.

              7.      Until the  actual transfer  of stock  certificates to  the
     holders  of voting trust certificates  hereunder, Voting  Trustee shall, in
     his uncontrolled discretion,  in respect of any  and all of the  stock held
     by him  hereunder, except as  in this Agreement  expressly limited, possess
     and be entitled  to exercise the right  to vote thereon for  every purpose,
     in person  or by  proxy, to  waive any stockholder's  privilege in  respect
     thereof, excluding  any right or  privilege to subscribe  for any increased
     stock, and to  consent to any lawful  corporate act of the  Corporation, as
     though  absolute owner of  said stock,  it being  expressly agreed  that no
     voting  right  shall  pass   to  others  by  or  under  said  voting  trust
     certificates, or  by or  under this  Agreement, or  by or  under any  other
     agreement,  express or implied.  Voting  Trustee is specifically authorized
     by  way of  example,  without limiting  his rights  hereunder, to  vote the
     stock held by  him for, or to consent  in respect thereof to,  any increase
     or  reduction   of  the  stock   of  the  Corporation,   any  agreement  of
     consolidation, merger, share exchange or  the sale or other  disposition of
     all, substantially all, or any part of  the property, assets and franchises
     of the  Corporation and the  granting, ratification or  confirmation of any
     option or options  therefor (whether executed before or after the execution
     of  this Agreement, and  whether or  not such  option or  options extend(s)
     beyond the term of  this Agreement), or the dissolution of the Corporation,

                                        - 2 -
<PAGE>






     and the judgment of Voting Trustee as to the adequacy of the  consideration
     thereby to  be  received  by  the  Corporation  and  Stockholder  (provided
     Stockholder and each holder  of a voting trust certificate of each class is
     treated uniformly,  share for share)  shall be conclusive  and binding upon
     Stockholder and  the holders of  voting trust certificates  and all persons
     claiming through or  under them.   Any person  acting as  a Voting  Trustee
     under  this  Agreement may,  directly  or indirectly,  transact  any lawful
     business  with  the  Corporation, notwithstanding  is  position  as  Voting
     Trustee.    Voting Trustee  may  also  serve  as  director and  compensated
     officer of the Corporation and may vote for himself, as such.  

              8.      In the event of the death,  resignation or other permanent
     inability to  serve  of  the  Voting  Trustee,  James  F.  Chen,  then  Not
     Applicable shall serve  as successor Voting  Trustee, and in  the event  of
     the death,  resignation, inability or  refusal to serve  of such successor,
     then  anything  contained  herein to  the  contrary  notwithstanding,  this
     Agreement  shall cease and  terminate without  notice by or  action of such
     successor Voting Trustee.   Such successor  shall serve  for the  unexpired
     term in  the place  and  stead of  the original  Voting Trustee,  as  above
     provided, and the  authority, powers, duties, obligations,  and limitations
     of the said original Voting Trustee shall devolve  upon such successor with
     the same effect as if such successor  had been the person named as original
     Voting  Trustee.   The successor  of  any person  acting as  Voting Trustee
     shall, by  written  agreement, undertake  the  performance of  this  voting
     trust in accordance with its terms.

              9.      At any  meeting of  the stockholders  of the  Corporation,
     any person then acting as a Voting Trustee may vote or  act in person or by
     proxy  to any other  person whether or  not such  other person is  a Voting
     Trustee, and  any person acting  as a  Voting Trustee may  give a power  or
     attorney to any  other person, whether or  not such other person  is acting
     as a Voting  Trustee, to sign  for him in case  of action taken in  writing
     without  a meeting.   Voting Trustee may adopt  his own  rules of procedure
     and may vote as stockholder of the Corporation in person or by proxy.

              10.     In voting the stock represented by  the stock certificates
     issued to Voting  Trustee as hereinbefore  provided, the  person acting  as
     Voting  Trustee  shall  exercise his  best  judgment  to the  end  that the
     business and affairs  of the Corporation shall be  properly managed; but no
     person acting  as Voting Trustee  assumes any responsibility  in respect of
     such management, or  in respect of any  action taken by Voting  Trustee, or
     of  his successor, or of any  person acting as such,  or taken in pursuance
     of  his consent thereto, or in pursuance of his vote so cast, and no person
     acting as a  Voting Trustee shall incur any responsibility, as stockholder,
     trustee or otherwise,  by reason of any error  of law, or of any  matter or
     thing done, except for his own wilful misconduct.

              11.     The  term   "Corporation",  for  the   purposes  of   this
     agreement and of all rights hereunder, including the issue  and delivery of
     stock  certificates,  shall   be  taken   to  mean  Virtual   Open  Network
     Environment   Corporation,  a  Maryland  corporation,  or  any  corporation
     successor to it.

              12.     Each   and  all  of  the  terms  and  provisions  of  this
     agreement shall  be and are  hereby made  binding upon  the parties,  their
     heirs, personal representatives, guardians and assigns.

              13.     Voting  Trustee shall  have  no duty  to hold  meetings of
     holders of voting trust certificates,  but he shall be entitled to do so if
     he wishes.  Ten days' written notice of every meeting  of holders of voting
     trust certificates shall  be given and such  notice shall state  the place,
     day and hour and the purpose,  if any, of such meeting, but any holder of a
     voting trust  certificate may waive  such notice in  writing, either before
     or after  the holding of the meeting.   No notice of  any adjourned meeting
     need be given.  Every such  meeting shall be held in the  State of Maryland
     at  a place  designated by  Voting Trustee,  unless  the holders  of voting
     trust certificates representing  two-thirds of the stock held by the Voting
     Trustee consent in  writing to the holding  thereof at another place.   The
     failure to  hold meetings  shall  not in  any manner  or degree  impair  or
     reduce the authority of Voting Trustee hereunder.

              14.     All notices to  be given to  the holders  of voting  trust
     certificates may  be given by  mailing the same  to the registered  holders
     thereof at their  addresses as  the same last  appear on  the voting  trust
     certificate  books of  Voting  Trustee, and  any  notice, mailed  as herein
     provided, shall be taken as though personally served  on all the holders of
     voting trust  certificates,  and such  mailing  shall  be the  only  notice
     required to be given under any provisions of this agreement.

              15.     This  agreement shall be filed  with Voting Trustee, and a
     duplicate hereof shall be filed in the principal office of Corporation.

              16.     The  Voting  Trustee,  hereby  accepts  the  above  trust,
     subject to all  of the terms, conditions and reservations herein contained,
     and agrees  that he  will exercise  the powers  and perform  the duties  of
     Voting Trustee as herein set forth, according to his best judgment.

              IN  WITNESS  WHEREOF, this  agreement  is  executed  at Rockville,
     Maryland.

                                VOTING TRUST AGREEMENT


              THIS  AGREEMENT, is  intended to  memorialize and  consolidate the
     terms of  prior  understandings  of  the  parties  and  is  therefore  made
     effective  as of the  15th day of October,  1994, by  and between Robert M.
     Zupnik  (hereinafter referred  to  as  "Stockholder"), and  James F.  Chen,
     Trustee,  and  his successor  and  successors  in the  Trust,  (hereinafter
     collectively referred to as "Voting Trustee"):

                      1.       Stockholder  has  assigned   and  transferred  to
     Voting Trustee the  number of Shares  of Virtual  Open Network  Environment
     Corporation  (the Corporation)  set opposite  his or  her signature hereto,
     for the  purpose of  vesting in  Voting Trustee,  as Trustee  of an  active
     trust, the right to vote thereon  and act in respect thereof, for a  period
     of two (2)  years from the date  hereof, subject to earlier  termination by
     the Trustee as hereinafter provided.

                      2.       Voting  Trustee  shall  cause  to  be  issued, in
     respect of the stock of the Corporation held by him,  pursuant to the terms
     hereof, a voting trust  certificate in a form acceptable to the parties and
     the   Corporation  (hereinafter   referred   to   as  the   "voting   trust
     certificate"):

                      3.       In  the event  that Voting Trustee  shall receive
     any additional  stock certificates of  Corporation by way  of dividend upon
     stock held  by  it under  this Agreement,  Voting Trustee  shall hold  such
     stock certificates likewise  subject to the  terms of  this Agreement,  and
     shall issue voting trust certificates representing  such stock certificates
     to the  respective registered holder  of the then  outstanding voting trust
     certificate entitled to such dividend.

                      4.       Voting Trustee  shall execute any and  all of the
     said voting  trust certificates, and  no voting trust  certificate shall be
     valid unless duly  signed by Voting Trustee.  Each voting trust certificate
     shall  be transferable  on  the voting  trust  certificate books  of Voting
     Trustee  (which shall be  kept for that  purpose at the  office of the said
     Trustee) by  the registered  holder thereof,  either in  person of by  duly
     authorized attorney,  upon the surrender  of such voting trust  certificate
     properly endorsed for transfer.   Until so transferred, the  Voting Trustee
     may  treat the  registered  holder of  voting  trust certificates  as owner
     thereof for  all purposes, except  that the delivery  of stock certificates
     hereunder and  certain payments hereunder,  as hereinafter provided,  shall
     not be made without surrender of such voting trust certificates.

                      5.       Until  the  termination of  this  Agreement  each
     registered holder  of  a voting  trust  certificate  shall be  entitled  to
     receive promptly  from  Voting Trustee  payments  equal  to the  amount  of
     dividends  (other  than  dividends  represented by  capital  stock  of  the
     Corporation) or other  distributions if  any, collected by  Voting Trustees
     upon the number of shares of stock of the  Corporation standing in the name
     of  such  registered  holder,  and  any  payment  representing  the  amount
     received upon  redemption or sale of  any common stock, represented  by the
     voting trust certificate  or certificates held by him, subject, however, to
<PAGE>






     the terms and conditions  of this Agreement.   Those registered as  holders
     of voting  trust certificates  on the dates  fixed as  record dates by  the
     Corporation for  dividends  and  for  the  allotment  of  rights  shall  be
     entitled  to  such payments  and  to any  rights  to the  benefit  of which
     holders of voting  trust certificates may be entitled under this Agreement.
     Voting Trustee may, in  his discretion, from time to time, close the voting
     trust certificate books against  transfers of voting trust certificates for
     the purpose of  determining the voting trust certificate holder entitled to
     such payments or  to such  rights, or for  the purpose  of determining  the
     voting trust certificate holder entitled to vote at  any meeting thereof or
     to do any thing or act to be done or performed by said holders.

                      6.       This Agreement shall terminate two (2) years from
     its effective date without notice by or action  of the Voting Trustee; but,
     at any  earlier time,  it may be  terminated by  the written action  of the
     Voting Trustee, in  his uncontrolled discretion, by  signing a  declaration
     to that effect and sending a copy of the  same to each registered holder of
     voting trust  certificates  issued hereunder.    Upon termination  of  this
     Agreement as  above specified,  Voting Trustee,  in exchange  for, or  upon
     surrender of,  any voting  trust certificate  then  outstanding, shall,  in
     accordance  with the  terms  hereof,  and out  of  the  stock held  by  him
     hereunder, deliver proper certificates of  stock of the Corporation  to the
     holders of voting  trust certificates and thereupon all liability of Voting
     Trustee,  or his  successors,  or successor,  or of  any  of them,  for the
     delivery of  said stock  certificates shall  cease and  terminate.   Voting
     Trustee may call upon and require the  holders of voting trust certificates
     to surrender them  in exchange for certificates  of stock of the  number of
     shares to which they are entitled hereunder.

                      7.       Until the actual transfer  of stock  certificates
     to  the  holders of  voting  trust certificates  hereunder,  Voting Trustee
     shall, in  his uncontrolled discretion,  in respect of  any and all of  the
     stock held  by  him  hereunder,  except  as  in  this  Agreement  expressly
     limited, possess and be entitled to exercise the right to vote thereon  for
     every purpose, in  person or by proxy, to waive any stockholder's privilege
     in respect  thereof, excluding any right or privilege  to subscribe for any
     increased  stock,  and to  consent  to  any  lawful corporate  act  of  the
     Corporation, as though  absolute owner of  said stock,  it being  expressly
     agreed that no voting  right shall pass to  others by or under  said voting
     trust certificates,  or by  or under  this Agreement,  or by  or under  any
     other agreement,  express  or  implied.   Voting  Trustee  is  specifically
     authorized by way  of example, without  limiting his  rights hereunder,  to
     vote the stock held by  him for, or to  consent in respect thereof to,  any
     increase or reduction  of the  stock of the  Corporation, any agreement  of
     consolidation, merger, share exchange or  the sale or other  disposition of
     all, substantially all,  or any part of the property, assets and franchises
     of the  Corporation and the  granting, ratification or  confirmation of any
     option or options  therefor (whether executed before or after the execution
     of this  Agreement, and  whether or  not such  option or options  extend(s)
     beyond the term of this Agreement), or the dissolution of the  Corporation,
     and the judgment of  Voting Trustee as to the adequacy of the consideration
     thereby  to be  received  by  the  Corporation  and  Stockholder  (provided

                                          2
<PAGE>






     Stockholder and each holder of a voting trust certificate of each class  is
     treated uniformly,  share for share)  shall be conclusive  and binding upon
     Stockholder and  the holders of  voting trust certificates  and all persons
     claiming  through or under  them.   Any person  acting as a  Voting Trustee
     under  this Agreement  may,  directly or  indirectly,  transact any  lawful
     business  with  the  Corporation, notwithstanding  is  position  as  Voting
     Trustee.    Voting Trustee  may  also  serve  as  director and  compensated
     officer of the Corporation and may vote for himself, as such.

                      8.       In the  event of the death,  resignation or other
     permanent inability to  serve of the  Voting Trustee,  James F. Chen,  then
     /s/  Charles C. Chen  shall serve as successor  Voting Trustee,  and in the
     event of  the death, resignation,  inability or  refusal to  serve of  such
     successor, then anything contained herein to  the contrary notwithstanding,
     this Agreement  shall cease and  terminate without notice  by or action  of
     such successor  Voting  Trustee.    Such  successor  shall  serve  for  the
     unexpired term in  the place and stead  of the original Voting  Trustee, as
     above  provided,  and  the  authority,  powers,  duties,  obligations,  and
     limitations of the  said original Voting  Trustee shall  devolve upon  such
     successor with  the same effect  as if such  successor had been the  person
     named as original  Voting Trustee.  The  successor of any person  acting as
     Voting  Trustee shall,  by written agreement,  undertake the performance of
     this voting trust in accordance with its terms.

                      9.       At  any  meeting  of  the  stockholders  of   the
     Corporation,  any person then acting as a Voting Trustee may vote or act in
     person or by proxy to any other  person whether or not such other person is
     a Voting  Trustee, and  any person acting  as a  Voting Trustee may  give a
     power or attorney  to any other person, whether or not such other person is
     acting  as a Voting  Trustee, to sign  for him in  case of  action taken in
     writing without  a meeting.   Voting  Trustee may  adopt his  own rules  of
     procedure and may  vote as stockholder of  the Corporation in person  or by
     proxy.

                      10.      In  voting the  stock  represented by  the  stock
     certificates issued to Voting Trustee as hereinbefore provided,  the person
     acting as Voting  Trustee shall exercise his best  judgment to the end that
     the business and affairs of the Corporation shall be  properly managed; but
     no person  acting as Voting  Trustee assumes any  responsibility in respect
     of such management,  or in respect of  any action taken by  Voting Trustee,
     or  of  his  successor,  or of  any  person  acting as  such,  or  taken in
     pursuance of his  consent thereto, or in pursuance of his vote so cast, and
     no  person acting  as a Voting  Trustee shall incur  any responsibility, as
     stockholder, trustee  or otherwise, by  reason of any  error of law, or  of
     any matter or thing done, except for his own wilful misconduct.

                      11.      The term "Corporation", for  the purposes of this
     agreement and of all rights hereunder, including  the issue and delivery of
     stock   certificates,  shall   be  taken  to   mean  Virtual  Open  Network
     Environment  Corporation,  a  Maryland  corporation,   or  any  corporation
     successor to it.

                      12.      Each and all of the terms and provisions  of this
     agreement shall  be and are  hereby made  binding upon  the parties,  their
     heirs, personal representatives, guardians and assigns.

                      13.      Voting  Trustee  shall  have   no  duty  to  hold
     meetings of holders of voting trust certificates, but he shall be  entitled
     to do  so if  he wishes.   Ten  days' written  notice of  every meeting  of
     holders  of voting trust certificates shall be  given and such notice shall
     state the place, day  and hour and  the purpose, if  any, of such  meeting,
     but any  holder of  a voting  trust certificate  may waive  such notice  in
     writing, either before or after the  holding of the meeting.  No  notice of
     any adjourned meeting need  be given.  Every such meeting shall  be held in
     the State of  Maryland at a place designated  by Voting Trustee, unless the
     holders of  voting trust certificates representing  two-thirds of the stock
     held  by the Voting  Trustee consent in writing  to the  holding thereof at
     another place.   The failure to  hold meetings shall  not in any manner  or
     degree impair or reduce the authority of Voting Trustee hereunder.

                      14.      All notices to be given to the holders  of voting
     trust  certificates may  be given  by mailing  the same  to the  registered
     holders thereof at  their addresses as the  same last appear on  the voting
     trust certificate  books  of Voting  Trustee,  and  any notice,  mailed  as
     herein provided, shall  be taken  as though  personally served  on all  the
     holders of  voting trust certificates, and  such mailing shall  be the only
     notice required to be given under any provisions of this agreement.

                      15.      This  agreement  shall  be   filed  with   Voting
     Trustee, and a  duplicate hereof shall be filed  in the principal office of
     Corporation.

                      16.      The  Voting  Trustee, hereby  accepts  the  above
     trust, subject  to all  of the  terms, conditions  and reservations  herein
     contained,  and agrees  that he  will exercise  the powers  and perform the
     duties  of  Voting Trustee  as  herein  set forth,  according  to  his best
     judgment.

                      IN  WITNESS   WHEREOF,  this  agreement   is  executed  at
     Rockville, Maryland.

                                VOTING TRUST AGREEMENT

              THIS  AGREEMENT, is  intended to  memorialize and  consolidate the
     terms of  prior  understandings  of  the  parties  and  is  therefore  made
     effective as of  the 15th day  of October, 1994, by  and between Dennis  E.
     Winson (hereinafter  referred  to as  "Stockholder"),  and James  F.  Chen,
     Trustee, and  his  successor  and successors  in  the  Trust,  (hereinafter
     collectively referred to as "Voting Trustee"):

                      1.       Stockholder  has  assigned   and  transferred  to
     Voting Trustee the  number of Shares  of Virtual  Open Network  Environment
     Corporation (the  Corporation) set  opposite his  or her signature  hereto,
     for the  purpose of  vesting in  Voting Trustee,  as Trustee  of an  active
     trust,  the right to vote thereon and act  in respect thereof, for a period
     of two (2)  years from the date  hereof, subject to earlier  termination by
     the Trustee as hereinafter provided.

                      2.       Voting  Trustee  shall cause  to  be  issued,  in
     respect of the stock of  the Corporation held by him, pursuant to the terms
     hereof, a voting trust certificate in a form  acceptable to the parties and
     the   Corporation  (hereinafter   referred   to   as  the   "voting   trust
     certificate"):

                      3.       In the  event that  Voting Trustee  shall receive
     any additional  stock certificates of  Corporation by way  of dividend upon
     stock  held by  it under  this Agreement,  Voting Trustee  shall hold  such
     stock certificates likewise  subject to the  terms of  this Agreement,  and
     shall issue voting trust certificates representing  such stock certificates
     to the  respective registered holder  of the then  outstanding voting trust
     certificate entitled to such dividend.

                      4.       Voting Trustee  shall execute any and  all of the
     said voting  trust certificates, and  no voting trust  certificate shall be
     valid  unless duly signed by Voting Trustee.  Each voting trust certificate
     shall  be transferable  on  the voting  trust  certificate books  of Voting
     Trustee (which  shall be kept  for that purpose at  the office of  the said
     Trustee) by  the registered  holder thereof,  either in person  or by  duly
     authorized attorney,  upon the surrender of  such voting  trust certificate
     properly endorsed for transfer.   Until so transferred, the  Voting Trustee
     may  treat the  registered  holder of  voting  trust certificates  as owner
     thereof for  all purposes, except  that the delivery  of stock certificates
     hereunder and  certain payments hereunder,  as hereinafter provided,  shall
     not be made without surrender of such voting trust certificates.

                      5.       Until the  termination  of  this  Agreement  each
     registered holder  of  a voting  trust  certificate  shall be  entitled  to
     receive promptly  from  Voting Trustee  payments  equal  to the  amount  of
     dividends  (other  than  dividends represented  by  capital  stock  of  the
     Corporation)  or other  distributions if any,  collected by Voting Trustees
     upon the number of  shares of stock of the Corporation standing in the name
     of  such  registered  holder,  and  any  payment  representing  the  amount
     received upon redemption  or sale of any  common stock, represented  by the
     voting trust certificate  or certificates held by him, subject, however, to
     the terms and  conditions of this Agreement.   Those registered as  holders
<PAGE>






     of  voting trust certificates  on the  dates fixed  as record dates  by the
     Corporation for  dividends  and  for  the  allotment  of  rights  shall  be
     entitled to  such  payments and  to  any rights  to  the benefit  of  which
     holders of voting  trust certificates may be entitled under this Agreement.
     Voting Trustee may, in his discretion, from time  to time, close the voting
     trust certificate  books against transfers of voting trust certificates for
     the purpose of  determining the voting trust certificate holder entitled to
     such payments  or to  such rights, or  for the  purpose of determining  the
     voting trust certificate holder entitled to vote  at any meeting thereof or
     to do any thing or act to be done or performed by said holders.

                      6.       This Agreement shall terminate two (2) years from
     its effective date without notice by or action of the Voting Trustee;  but,
     at any  earlier time,  it may be  terminated by the  written action  of the
     Voting  Trustee, in his uncontrolled  discretion, by  signing a declaration
     to that effect and sending  a copy of the same to each registered holder of
     voting  trust certificates  issued  hereunder.   Upon  termination of  this
     Agreement as  above specified,  Voting Trustee,  in exchange  for, or  upon
     surrender of,  any voting  trust  certificate then  outstanding, shall,  in
     accordance  with the  terms  hereof,  and out  of  the  stock held  by  him
     hereunder, deliver proper certificates of  stock of the Corporation  to the
     holders of voting  trust certificates and thereupon all liability of Voting
     Trustee,  or his  successors, or  successor, or  of  any of  them, for  the
     delivery of  said stock  certificates shall  cease and  terminate.   Voting
     Trustee may call upon and  require the holders of voting trust certificates
     to surrender them  in exchange for certificates  of stock of the  number of
     shares to which they are entitled thereunder.

                      7.       Until the  actual transfer  of stock certificates
     to  the holders  of  voting trust  certificates  hereunder, Voting  Trustee
     shall, in his uncontrolled  discretion, in  respect of any  and all of  the
     stock held  by  him  hereunder,  except  as  in  this  Agreement  expressly
     limited, possess and be  entitled to exercise the right to vote thereon for
     every  purpose, in person or by proxy, to waive any stockholder's privilege
     in respect thereof, excluding any right  or privilege to subscribe for  any
     increased stock,  and  to  consent  to any  lawful  corporate  act  of  the
     Corporation, as though  absolute owner of  said stock,  it being  expressly
     agreed that no  voting right shall pass  to others by or under  said voting
     trust certificates,  or by  or under  this Agreement,  or by  or under  any
     other  agreement,  express  or implied.    Voting  Trustee is  specifically
     authorized by way  of example, without  limiting his  rights hereunder,  to
     vote  the stock held by  him for, or to consent  in respect thereof to, any
     increase  or reduction  of the stock  of the Corporation,  any agreement of
     consolidation, merger, share exchange or  the sale or other  disposition of
     all,  substantially all, or any part of the property, assets and franchises
     of the  Corporation and the  granting, ratification or  confirmation of any
     option or options  therefor (whether executed before or after the execution
     of this  Agreement, and  whether or  not such option  or options  extend(s)
     beyond the term of this Agreement), or the dissolution  of the Corporation,
     and  the  judgement   of  Voting  Trustee   as  to  the  adequacy   of  the
     consideration thereby  to be received  by the  Corporation and  Stockholder
     (provided Stockholder  and each  holder of  a voting  trust certificate  of

                                          2
<PAGE>






     each class is treated  uniformly, share for share) shall  be conclusive and
     binding upon Stockholder and the  holders of voting trust  certificates and
     all persons claiming  through or under them.  Any person acting as a Voting
     Trustee  under  this Agreement  may, directly  or indirectly,  transact any
     lawful  business  with  the Corporation,  notwithstanding  is  position  as
     Voting Trustee.  Voting Trustee may also serve as director and  compensated
     officer of the Corporation and may vote for himself, as such.

                      8.       In the  event of the death,  resignation or other
     permanent  inability to  serve of the  Voting Trustee, James  F. Chen, then
     Charles C. Chen shall  serve as successor Voting Trustee, and in  the event
     of  the  death,   resignation,  inability  or  refusal  to  serve  of  such
     successor, then anything contained herein to  the contrary notwithstanding,
     this Agreement shall  cease and terminate  without notice by  or action  of
     such successor  Voting  Trustee.    Such  successor  shall  serve  for  the
     unexpired term in  the place and stead  of the original Voting  Trustee, as
     above  provided,  and  the  authority,  powers,  duties,  obligations,  and
     limitations of the  said original Voting  Trustee shall  devolve upon  such
     successor with the same  effect as  if such successor  had been the  person
     named as original  Voting Trustee.  The  successor of any person  acting as
     Voting Trustee  shall, by written  agreement, undertake the performance  of
     this voting trust in accordance with its terms.

                      9.       At  any  meeting   of  the  stockholders  of  the
     Corporation, any person then acting as a Voting Trustee  may vote or act in
     person or by  proxy to any other person whether or not such other person is
     a Voting  Trustee, and  any person acting  as a Voting  Trustee may  give a
     power or attorney to any other person, whether or not such  other person is
     acting as a  Voting Trustee, to  sign for  him in case  of action taken  in
     writing without  a meeting.   Voting  Trustee may  adopt his  own rules  of
     procedure and may  vote as stockholder of  the Corporation in person  or by
     proxy.

                      10.      In voting  the  stock  represented by  the  stock
     certificates issued to Voting Trustee as  hereinbefore provided, the person
     acting as Voting Trustee shall exercise his  best judgment to the end  that
     the business and affairs of the Corporation  shall be properly managed; but
     no person  acting as Voting  Trustee assumes any  responsibility in respect
     of such management,  or in respect of  any action taken by  Voting Trustee,
     or  of  his  successor, or  of  any  person acting  as  such,  or  taken in
     pursuance of his consent thereto, or in pursuance of his vote  so cast, and
     no person  acting as a  Voting Trustee shall  incur any responsibility,  as
     stockholder, trustee or otherwise,  by reason  of any error  of law, or  of
     any matter or thing done, except for his own wilful misconduct.

                      11.      The term "Corporation", for the purposes of  this
     agreement and of all rights  hereunder, including the issue and delivery of
     stock  certificates,   shall  be  taken   to  mean  Virtual  Open   Network
     Environment  Corporation,  a  Maryland  corporation,  or  any   corporation
     successor to it.

                      12.      Each and all of the terms and provisions  of this
     agreement shall  be and are  hereby make  binding upon  the parties,  their
     heirs, personal representatives, guardians and assigns.

                      13.      Voting  Trustee  shall  have   no  duty  to  hold
     meetings of holders of voting trust certificates, but he shall be  entitled
     to do  so if  he wishes.   Ten  days' written  notice of  every meeting  of
     holders  of voting trust certificates shall be  given and such notice shall
     state the place, day  and hour and  the purpose, if  any, of such  meeting,
     but any  holder of  a voting  trust certificate  may waive  such notice  in
     writing, either before or after the  holding of the meeting.  No  notice of
     any adjourned meeting need  be given.  Every such meeting shall  be held in
     the State of  Maryland at a place designated  by Voting Trustee, unless the
     holders of  voting trust certificates representing  two-thirds of the stock
     held  by the Voting  Trustee consent in writing  to the  holding thereof at
     another place.   The failure to  hold meetings shall  not in any manner  or
     degree impair or reduce the authority of Voting Trustee hereunder.

     trust  certificates may  be given  by mailing  the same  to the  registered
     holders thereof at  their addresses as the  same last appear on  the voting
     trust certificate  books  of Voting  Trustee,  and  any notice,  mailed  as
     herein provided, shall  be taken  as though  personally served  on all  the
     holders of  voting trust certificates, and  such mailing shall  be the only
     notice required to be given under any provisions of this agreement.

                      15.      This  agreement  shall  be   filed  with   Voting
     Trustee, and a  duplicate hereof shall be filed  in the principal office of
     Corporation.

                      16.      The  Voting  Trustee, hereby  accepts  the  above
     trust, subject  to all  of the  terms, conditions  and reservations  herein
     contained,  and agrees  that he  will exercise  the powers  and perform the
     duties  of  Voting Trustee  as  herein  set forth,  according  to  his best
     judgment.

              THIS AGREEMENT, made and entered as of this 12th day of June,

              WHEREAS, the Company wishes to assure itself of the services of
     Executive for the period provided in this Agreement, and Executive is

     under the circumstances set forth herein, including after the happening of
     a Change in Control (as defined herein); and 

              WHEREAS, the parties intend that the provisions of this Agreement
     shall be in lieu of Executive's right to make any claim or demand with

     policy of the Company; 

              NOW, THEREFORE, in consideration of the mutual covenants herein

              3.      Term and Duties.
                      ---------------

              (a)     Term of Employment.  The period of Executive's employment
     under this Agreement with the Company (i) shall be deemed to have
     commenced as of the Effective Date, and (ii) shall continue for a period
     of twenty-four (24) full calendar months thereafter and any extensions
     thereafter, unless this Agreement is earlier terminated in accordance with
     the terms hereof.  The period of employment shall automatically be
     extended without further action by the respective parties as of June 12,
     1997 and each succeeding June 12 for the twenty-four (24) month period
     beginning on June 12, 1997 and each June 12 thereafter, unless either
     party shall have served written notice upon the other prior to June 12,
     1997 or prior to June 12 of each succeeding year, as the case may be, of
     his or its intention that this Agreement shall terminate at the end of the
     twenty-four (24)  month period that begins with the June 12 following such
     date of written notice.

              (b)     Duties.  During the period of his employment hereunder by
     the Company and except for illness, reasonable vacation periods having an
     aggregate duration of not less than that provided pursuant to the
     Company's practices in effect on the Effective Date, and reasonable leaves
     of absence, Executive shall devote all his business time, attention,
     skill, and efforts to the faithful performance of his duties hereunder.

              (c)     Headquarters Location.  The Company agrees to maintain
     Executive's offices within Montgomery County in the State of Maryland
     ("Base Employment Area").

              4.      Compensation and Reimbursement of Expenses.
                      ------------------------------------------

              (a)     Compensation.
                      ------------

                      (i)  For all services rendered by Executive in
              any capacity during his employment under this Agreement
              (including, without limitation, services as an executive,
              officer, or director of the Company, or any subsidiary or
              affiliate of the Company, or as a member of any committee
              of the Board of Directors of the Company or any
              subsidiary or affiliate of the Company), the Company
              shall pay Executive as compensation (A) an annual salary
              ("Base Salary") and (B) such bonus for such period, if
              any, as may be awarded to Executive from time to time by
              the Board or by a committee designated by the Board. 
              Effective the Effective Date and until adjusted in
              accordance with the provisions hereof, Base Salary shall
              be paid at the rate of not less than $125,000 per year. 
              Such bonus shall be based on results of operations,
              special contributions made by Executive, seniority,
              competitive conditions in the Company's industry, and

                                        - 2 -
<PAGE>






              such other factors as the Board (or a committee or
              committees designated by the Board) shall consider
              relevant.

                      (ii)      Such salary shall be payable in
              accordance with the customary payroll practices of the
              Company, but in no event less frequently than monthly,
              and any such bonus shall be payable in the manner
              specified by the Board, or committee of the Board, at the
              time any such bonus is awarded.

                      (iii) Executive's Base Salary shall be reviewed
              promptly following the completion of the Company's
              initial public offering and thereafter at least annually. 
              Such review shall be conducted by the Board or a
              committee designated by the Board.  As a result of such
              review, the Board or committee may, in its discretion,
              increase (to reflect Executive's performance, duties, and
              responsibilities and to maintain a compensation level
              comparable to that of similarly situated executives in
              the Company's industry), but not decrease, Executive's
              Base Salary then in effect; provided, however, that the
              Board or such committee may, in its discretion and
              without Executive's consent, proportionally reduce
              Executive's Base Salary if, at the same time, it reduces
              the salaries of all the Company's executive officers;
              provided further, however, that in no event shall
              Executive's Base Salary be reduced below $125,000 per
              year without Executive's consent.  After any adjustment
              following the Company's initial public offering, the
              Board or committee may not increase Executive's Base
              Salary for any one year by an amount greater than 50% of
              Executive's then Base Salary.

                      (iv)  Executive shall not be entitled to receive
              any fees for service as a director, officer, or employee
              of any subsidiary or affiliate of the Company.

              (b)     Reimbursement of Expenses.  The Company shall pay or
     reimburse Executive, in accordance with such policies and procedures as
     the Board may establish from time to time, for all reasonable travel and
     other expenses incurred by Executive in the performance of his obligations
     under this Agreement.

              5.      Participation in Benefit Plans.  The payments provided
     for in this Agreement, except where specifically provided otherwise, are
     in addition to any other benefits to which Executive may be, or may
     become, entitled under any of the Company's group hospitalization, health,
     dental care, and/or sick-leave plans; life, other insurance and/or death
     benefit plans; travel and/or accident insurance plans; deferred
     compensation plans; capital accumulation programs; restricted and/or stock
     purchase plans; stock option plans; retirement income and/or pension

                                        - 3 -

     plans; supplemental pension plans; excess benefit plans; short- and long-
     term disability programs; and other present and future group employee
     benefit plans and programs for which Company executives are or shall
     become eligible.  Executive shall be eligible to receive, during the
     period of his employment under this Agreement and during any subsequent
     period for which he shall be entitled to receive payments from the Company
     under Section 6, all of the foregoing benefits and emoluments for which
     executives are eligible under every such plan and program to the extent
     permissible under the general terms and provisions of such plans and
     programs and in accordance with the provisions thereof.  Nothing contained
     in this Agreement shall prevent the Board from amending or otherwise
     altering any such plan, program, or arrangement as long as such amendment
     or alteration equitably affects all the Company's executive officers (of
     the level of vice president or above).

              6.      Termination of Employment.  Executive's employment under
     this Agreement may be terminated by the Company or Executive as follows:

              (a)     Disability.

                      (i)  If Executive fails to perform his duties
              under this Agreement on account of Disability (as
              hereinafter defined), the Company may give notice to
              Executive to terminate this Agreement on a date not less
              than thirty (30) days thereafter ("Notice Period") and,
              if Executive has not resumed full performance of his
              duties under this Agreement within such Notice Period,
              then Executive's employment under this Agreement will
              terminate on the date provided in the notice ("Disability
              Termination Date").

                      (ii)  During any period of Disability, the
              Company shall maintain and pay for health insurance
              benefits for Executive at least equal to those he had at
              the commencement of such Disability.

                      (iii)  As used in this Agreement, the term
              "Disability" shall mean the complete inability of
              Executive to perform his duties under this Agreement by
              reason of his total and permanent disability, as
              determined by an independent physician selected with the
              approval of the Board and Executive.

              (b)     Death.  If Executive dies while employed under this
     Agreement, his employment under this Agreement will terminate as of the
     date of his death ("Date of Death").  Within thirty (30) days after the
     Date of Death, the Company shall pay to Executive's legal representative
     Executive's Base Salary as then in effect that has accrued to the last day
     of the month in which the Date of Death occurs.

              (c)     Termination by Executive.  In the event that
     (i) Executive terminates his employment with the Company (other than

                                        - 4 -
<PAGE>






     because of his death) within two (2) years following a Change in Control
     (as hereinafter defined), (ii) the Company terminates Executive's
     employment for any reason (other than because of death, Disability, or
     "just cause" (as hereinafter defined)) within two (2) years following a
     Change in Control, (iii) Executive terminates his employment with the
     Company because of the Company's material breach of this Agreement, (iv)
     Executive's Base Salary, as in effect on the Effective Date or as the same
     may be increased from time to time, is reduced unless such reduction is
     permitted by this Agreement, or (v) the Company's principal executive
     offices are relocated to a location outside the Base Employment Area or
     the Company requires Executive to be based anywhere other than the
     Company's principal executive offices (except for required travel on the
     Company's business), then the Company shall pay Executive within ten (10)
     days following the date his employment with the Company is so terminated
     ("Executive Termination Date") as severance pay a lump sum payment equal
     to the sum of (A) the aggregate amount of the future Base Salary payments
     Executive would have received if he continued in the employ of the Company
     until twenty-four (24) months (thirty-six (36) months if an event
     described in clauses (i) or (ii) of this Section 6(c) occurs) following
     the Executive Termination Date and (B) Executive's projected bonus for the
     year in which the Executive Termination Date occurs, which shall be
     computed assuming that Executive had remained in the Company's employ
     until the end of that year and that all performance goals or other
     performance measures have been met at the then current level for the
     remainder of that year.  The payment required by clause (A) shall be
     calculated at the highest rate of Base Salary paid to Executive at any
     time under this Agreement with such payments discounted to present value
     at a discount rate equal to one percent (1%) above the per annum one-year
     Treasury Bill rate, as published in the Eastern Edition of the Wall Street
     Journal, on the Executive Termination Date (or the next preceding date on
     which such rate is published), applied to each such future payment from
     the time it would have become payable to the date Executive receives
     payment.  No termination of employment pursuant to this Section 6(c) shall
     operate to prohibit Executive from negotiating and entering into a new
     employment contract with the Company or such entity as survives the Change
     in Control.

              (d)     Retirement.  Executive shall be entitled to terminate his
     employment with the Company on, or at any date after, a date on which he
     is at least sixty-five (65) years old.  Any date on which Executive elects
     to retire shall be referred to as the "Retirement Termination Date."  The
     Company shall pay to Executive his Base Salary as then in effect that has
     accrued to the last day of the month in which the Retirement Termination
     Date occurs.

              (e)     Termination By The Company For Just Cause.
                      -----------------------------------------

                      (i)  The Company may terminate Executive's
              employment for "just cause" at any time by giving written
              notice thereof to Executive.  (Except as provided below,
              the date of such notice is the "Just Cause Termination

                                        - 5 -
<PAGE>






              Date" unless otherwise provided in the notice).  Within
              thirty (30) days after the Just Cause Termination Date,
              the Company shall pay to Executive his Base Salary as
              then in effect that has accrued to the Just Cause
              Termination Date.  For the purposes of this subparagraph,
              "just cause" shall mean termination because of
              Executive's personal dishonesty, willful misconduct,
              breach of fiduciary duty involving personal profit,
              intentional failure to perform stated duties, willful
              violation of any law, rule or regulation (other than
              traffic violations or similar offenses), or material
              breach of any provision of this Agreement.  Unless
              otherwise determined by the Board, Executive shall have
              no right to receive compensation or other benefits under
              this Agreement after a termination for just cause.

                      (ii)  Notwithstanding the foregoing, Executive
              shall not be deemed to have been terminated for just
              cause pursuant to this Section 6(e) unless and until he
              shall have received a copy of a resolution duly adopted
              by the affirmative vote of a majority of the Board, at a
              meeting held for that purpose, declaring that in the good
              faith opinion of the Board one or more of the conditions
              set forth in clause (i) of this Section 6(e) has occurred
              and specifying the particulars thereof.

              7.      Change in Control.  For purposes of this Agreement, a
     "Change in Control" shall mean the occurrence, after the Effective Date,
     of any of the following events, directly or indirectly or in one or more
     series of transactions:

                      (i)  A consolidation or merger of the Company
              with any third party (which includes a single person or
              entity or a group of persons or entities acting in
              concert) not wholly owned directly or indirectly by the
              Company (a "Third Party"), unless the Company is the
              entity surviving such merger or consolidation;

                      (ii)  A transfer of all or substantially all of
              the assets of the Company to a Third Party or a complete
              liquidation or dissolution of the Company;

                      (iii)  A Third Party (other than James F. Chen
              and his affiliates), directly or indirectly, through one
              or more subsidiaries or transactions or acting in concert
              with one or more persons or entities:

                               (A)     acquires beneficial
                      ownership of more than 20% of the
                      classes of stock of the Company entitled
                      to vote generally in the election of

                      Stock");

                               (B)  acquires irrevocable
                      proxies representing more than 20% of
                      the Voting Stock;

                               (C) acquires any combination of
                      beneficial ownership of Voting Stock and
                      irrevocable proxies representing more
                      than 20% of the Voting Stock; 

                               (D)  acquires the ability to
                      control in any manner the election of a
                      majority of the directors of the
                      Company; or

                               (E)  acquires the ability to
                      directly or indirectly exercise a
                      controlling influence over the
                      management or policies of the Company;

                      (iv)  any election has occurred of persons to the
              Board that causes a majority of the Board to consist of
              persons other than (A) persons who were members of the
              Board on the Effective Date and/or (B) persons who were
              nominated for election as members of the Board by the
              Board (or a committee of the Board) at a time when the
              majority of the Board (or of such committee) consisted of
              persons who were members of the Board on the Effective
              Date; provided, however, that any persons nominated for
              election by the Board (or a committee of the Board), a
              majority of whom are persons described in clauses (A)
              and/or (B), or are persons who were themselves nominated
              by such Board (or a committee of such Board), shall for
              this purpose be deemed to have been nominated by a Board
              composed of persons described in clause (A); or

                      (v)  A determination is made by the Securities
              and Exchange Commission ("SEC") or any similar agency
              having regulatory control over the Company that a change
              in control, as defined in the securities laws or
              regulations then applicable to the Company, has occurred.

     Notwithstanding any provision contained herein, a Change in Control shall
     not include any of the above described events if they are the result of a
     Third Party's inadvertently acquiring beneficial ownership or irrevocable
     proxies or a combination of both for 20% or more of the Voting Stock, and
     the Third Party as promptly as practicable thereafter divests itself of
     beneficial ownership or irrevocable proxies for a sufficient number of
     shares so that the Third Party no longer has beneficial ownership or


                                        - 7 -

     irrevocable proxies or a combination of both for 20% or more of the Voting
     Stock.

              8.      Excise Tax.
                      ----------

              (a)     Excess Parachute Payment.  Notwithstanding anything to
     the contrary in this Agreement, if tax counsel selected by the Company and
     acceptable to Executive determines that any portion of any payment by the
     Company to Executive under this Agreement or otherwise would constitute an
     "excess parachute payment," then the payments to be made to Executive by
     the Company shall be reduced such that the value of the aggregate payments
     that Executive is entitled to receive under this Agreement and any other
     agreement, plan or program of the Company shall be one dollar ($1.00) less
     than the maximum amount of payments that Executive may receive without
     becoming subject to the tax imposed by Section 4999 of the Code; provided,
     however, that the foregoing limitation shall not apply in the event that
     such tax counsel determines that the benefits to Executive on an after-tax
     basis (i.e., after federal, state, and local income and excise taxes) if
     such limitation is not applied would exceed the after-tax benefits to
     Executive if such limitation is applied.

              (b)     The Company Not Responsible for Excise Tax.  If the
     Internal Revenue Service assesses an excise tax against Executive pursuant
     to Sections 280G and 4999 of the Code, the Company shall be under no
     obligation to Executive with respect to the amount of (i) the excise tax
     or (ii) any additional federal income tax due from and payable by
     Executive as the result of his receipt of any payment hereunder or
     otherwise.

              9.      Covenant Not to Compete.  Executive covenants and agrees
     that, in consideration of the amounts to be paid Executive hereunder and
     other good and valuable consideration, for a period of two (2) years
     beyond the Retirement Termination Date or the Just Cause Termination Date
     (each a "Termination Date"), Executive shall not be employed as an
     executive officer of, control, manage, or otherwise participate in the
     management of the business of a "significant competitor" of the Company. 
     The term "significant competitor" shall mean any company or division of a
     company that, on the date of its employment of Executive, derives more
     than 50% of its gross revenues from network security products and/or
     services, or a company that owns or controls a majority of the voting
     securities of any such company.  The Company and Executive agree that the
     terms and conditions of this Section 9 shall survive the termination of
     this Agreement following the Termination Date.

              10.     Confidential Information.
                      ------------------------

              (a)  Executive shall not, directly or indirectly, during the term
     of his employment hereunder and at any time after a termination of his
     employment for any reason, to the detriment of the Company, knowingly
     divulge, disclose, disseminate, publish, reveal or otherwise communicate

                                        - 8 -
<PAGE>






     to any unauthorized person any Confidential Information relating to the
     Company, the Company's subsidiaries or affiliates, or to any of the
     businesses operated by any of them.

              (b)     Executive confirms that Confidential Information
     constitutes the exclusive property of the Company and the Company's
     subsidiaries and affiliates.  Upon a termination of his employment
     hereunder, Executive will promptly return to the Company all Materials
     (whether prepared by Executive or others) containing, constituting,
     embodying or illustrating Confidential Information, and all other property
     of the Company or of the Company's subsidiaries and affiliates then in his
     possession or custody.

              (c)     As used in this Section 10 the following terms shall have
     the following meanings:

                      (i)  the term "Confidential Information" means
              information disclosed to Executive or known to Executive
              as a consequence of or through his employment by the
              Company and not generally known in the Company's
              industry.  Such information includes, but is not limited
              to, information relating to the Company's products,
              research, development, accounting, finances, marketing,
              merchandising and selling, and specifically includes
              future business plans, client lists, lists of current and
              prospective employees and consultants, potential
              acquisition candidates, and training and operating
              methods and techniques.  The term "Confidential
              Information" does not include information that (A) at the
              time it was received by Executive was generally available
              to the public; (B) prior to its use by Executive, becomes
              generally available to the public through no act or
              failure of Executive; or (C) is received by  Executive
              from a person who is not a party to this Agreement and
              who is not under an obligation of confidence with respect
              to such information.

                      (ii)  "Materials" includes, but is not limited
              to, books, notebooks, documents, records, photographs,
              films, video tapes, audio tape recordings, computer
              disks, diskettes or other electronic or optical storage
              media, software and support materials, and similar or
              other materials.

              (d)     Executive shall not otherwise knowingly act or conduct
     himself (i) to the material detriment of the Company or the Company's
     subsidiaries or affiliates, or (ii) in a manner that is inimical or
     contrary to the interests thereof.

              (e)     The Company and Executive agree that the provisions of
     this Section 10 shall survive the termination of this Agreement for any
     reason whatsoever; provided, however, that this Section 10 shall become

                                        - 9 -
<PAGE>






     immediately inoperative and Executive shall no longer be bound by it in
     the event that Executive's employment with the Company is terminated
     following a Change in Control.

              11.     General Provisions.
                      ------------------

              (a)     Entire Agreement.  This Agreement contains the entire
     understanding between the parties hereto and supersedes any prior
     employment agreement between the Company and Executive.

              (b)     Consolidation, Merger, or Sale of Assets.  Nothing in
     this Agreement shall preclude the Company from consolidating or merging
     into or with, or transferring all or substantially all of its assets to,
     another corporation or corporations; provided, however, that such
     consolidation, merger or transfer shall not affect Executive's rights
     under Section 6(c) hereof.  Upon such a consolidation, merger, or transfer
     of assets and assumption, the term "the Company," as used herein, shall
     mean such other corporation or corporations, and this Agreement shall
     continue in full force and effect and such other corporation or
     corporations shall be liable for all payments to Executive under the
     Agreement.

              (c)     No Duty to Mitigate.  Executive shall not be required to
     mitigate the amount of any payment provided for in this Agreement by
     seeking other employment or otherwise, nor shall any amounts received from
     other employment or otherwise by Executive offset in any manner the
     obligations of the Company hereunder.

              (d)     Nonassignability.  Neither this Agreement nor any right,
     remedy, obligation or liability arising hereunder or by reason hereof is
     assignable by Executive, his beneficiaries, or legal representatives
     without the Company's prior written consent; provided, however, that
     nothing in this Section 11(d) shall preclude (i) Executive from
     designating a beneficiary to receive any benefit payable hereunder upon
     his death, or (ii) the executors, administrators, or other legal
     representatives of Executive or his estate from assigning any rights
     hereunder to the person or persons entitled thereto.

              (e)     No Attachment.  Except as required by law, no right to
     receive payments under this Agreement shall be subject to anticipation,
     commutation, alienation, sale, assignment, encumbrance, charge, pledge, or
     hypothecation or the execution, attachment, levy, or similar process or
     assignment by operation of law, and any attempt, voluntary or involuntary,
     to effect any such action shall be null, void and of no effect.

              (f)     General Creditor.  All payments required hereunder shall
     be made from the Company's general assets and Executive shall have no
     rights greater than the rights of a general creditor of the Company.

              (g)     Notices.  All notices and other communications required
     or permitted to be given under this Agreement shall be in writing and

                                        - 10 -

     shall be deemed to have been duly given if delivered personally or sent by
     certified mail, return receipt requested, first-class postage prepaid, to
     the parties to this Agreement at the following addresses:

                      (i)      if to the Company at:

                               Virtual Open Network Environment Corporation
                               1803 Research Boulevard
                               Suite 305
                               Rockville, Maryland  20850
                               Attention: Chief Financial Officer

                               and

                      (ii)     if to Executive at the address
                               set forth at the end of this
                               Agreement

     or to such other address as either party to this Agreement shall have last
     designated by notice to the other party.  All such notices and
     communications shall be deemed to have been received on the earlier of the
     date of receipt or the third business day after the date of mailing
     thereof.

              (h)     Binding Effect; Benefits.  This Agreement shall be
     binding upon and inure to the benefit of the parties to this Agreement and
     their respective successors and permitted assigns.  Nothing in this
     Agreement, express or implied, is intended or shall be construed to give
     any person, other than the parties to this Agreement or their respective
     successors or permitted assigns, any legal or equitable right, remedy, or
     claim under or in respect of any agreement or any provision contained
     herein.

              (i)     Dispute Resolution.  Any controversy or claim arising out
     of or relating to this Agreement or the breach thereof shall be settled by
     arbitration in accordance with the then existing Commercial Arbitration
     Rules of the American Arbitration Association ("AAA").

                      (i)  The matter shall be heard and decided, and
              award rendered, by a panel of three (3) arbitrators
              ("Arbitration Panel").  The Company and Executive shall
              each select one (1) arbitrator from the AAA National
              Panel of Commercial Arbitrators ("Commercial Panel") and
              the AAA shall elect a third arbitrator from the
              Commercial Panel.  The award rendered by the Arbitration
              Panel shall be final and binding as between the parties
              hereto and their heirs, executors, administrators,
              successors, and assigns.  Judgment on the award may be
              entered by any court having jurisdiction thereof.

                      (ii)  The parties irrevocably consent to the
              jurisdiction of the Federal and state courts located in

                                        - 11 -
<PAGE>






              the State of Maryland for this purpose.  Each such
              arbitration proceeding shall be located in Maryland.

                      (iii)  The arbitrators may, in the course of the
              proceedings, order any provisional remedy or conservatory
              measure (including, without limitation, attachment,
              preliminary injunction, or the deposit of specified
              security) that the arbitrators consider to be necessary,
              just, and equitable.  The failure of a party to comply
              with such an interim order may, after due notice and
              opportunity to cure such noncompliance, be treated by the
              arbitrators as a default, and some or all of the claims
              or defenses of the defaulting party may be stricken and
              partial or final award entered against such party, or the
              arbitrators may impose such lesser sanctions as the
              arbitrators may deem appropriate.  A request for interim
              or provisional relief by a party to a court shall not be
              deemed incompatible with the agreement to arbitrate or a
              waiver of that agreement.

                      (iv)  The parties acknowledge that any remedy at
              law for breach of this Agreement may be inadequate, and
              that, in the event of a breach of Sections 9 and 10 by
              Executive, any remedy at law would be inadequate in that
              any such breach would cause irreparable competitive harm
              to the Company.  Consequently, in addition to any other
              relief that may be available, the arbitrators may also
              order temporary and permanent injunctive relief,
              including, without limitation, specific performance,
              without the necessity of the prevailing party proving
              actual damages and without regard to the adequacy of any
              remedy at law.

                      (v)      In the event Executive is the prevailing
              party in such arbitration, then Executive shall be
              entitled to reimbursement by the Company for all
              reasonable legal and other professional fees and expenses
              incurred by him in such arbitration or in enforcing the
              award, including reasonable attorneys' fees.

              (j)     Waiver.  Either party hereto may by written notice to the
     other (i) extend the time for the performance of any of the obligations or
     other actions of the other under this Agreement; (ii) waive compliance
     with any of the conditions or covenants of the other contained in this
     Agreement; and (iii) waive or modify performance of any of the obligations
     of the other under this Agreement.  Except as provided in the preceding
     sentence, no action taken pursuant to this Agreement, including, without
     limitation, any investigation by or on behalf of any party, shall be
     deemed to constitute a waiver by the party taking such action of
     compliance with any representation, warranty, covenant, or agreement
     contained herein.  The waiver by any party hereto of a breach of any
     provision of this Agreement shall not operate or be construed as a waiver

                                        - 12 -
<PAGE>






     of any preceding or succeeding breach, and no failure by either party to
     exercise any right or privilege hereunder shall be deemed a waiver of such
     party's rights or privileges hereunder or shall be deemed a waiver of such
     party's rights to exercise that right or privilege at any subsequent time
     or times hereunder.

              (k)     Amendment.  This Agreement may be terminated, amended,
     modified, or supplemented only by a written instrument executed by
     Executive and the Company.

              (l)     Governing Law.  This Agreement shall be governed by and
     construed in accordance with the law of the State of Maryland, regardless
     of the law that might be applied under principles of conflict of laws;
     provided, however, that any arbitration under Section 11(i) hereof shall
     be conducted in accordance with the United States Arbitration Act as then
     in force.

              (m)     Section and Other Headings.  The section and other
     headings contained in this Agreement are for reference purposes only and
     shall not affect the meaning or interpretation of this Agreement.

              (n)     Withholding of Taxes.  The Company may withhold from
     amounts required to be paid to Executive hereunder any applicable federal,
     state, local, and other taxes with respect thereto; provided, however,
     that the Company shall promptly pay over the amounts so withheld to the
     appropriate taxing bodies and provide to Executive appropriate statements
     on forms proscribed for such purposes on the amounts so withheld.

              (o)     Severability.  If, for any reason, any provision of this
     Agreement is held invalid, such invalidity shall not affect any other
     provision of this Agreement not held so invalid, and each such other
     provision shall, to the full extent consistent with law, continue in full
     force and effect.  If any provision of this Agreement shall be held
     invalid in part, such invalidity shall in no way affect the rest of such
     provision not held so invalid, and the rest of such provision, together
     with all other provisions of this Agreement, shall to the full extent
     consistent with law continue in full force and effect.  

              (p)     Counterparts.  This Agreement may be executed in any
     number of counterparts, each of which shall be deemed to be an original
     and all of which together shall be deemed to be one and the same
     instrument.

                    VIRTUAL OPEN NETWORK ENVIRONMENT CORPORATION
                         1995 NON-STATUTORY STOCK OPTION PLAN

              This 1995 Non-Statutory Stock Option Plan ("Plan") is adopted as
     of May 15, 1995 by Virtual Open Network Environment Corporation
     ("Corporation").

              1.      PURPOSE OF PLAN.  The purpose of this Plan is to attract
     and retain outstanding key employees, to furnish existing key employees
     with further inducement to continue their employment with the Corporation
     and to encourage key employees to acquire a greater stake in the
     Corporation's success and, thus, provide an additional incentive for them
     to promote the Corporation's best interests.

              2.      SHARES RESERVED FOR PLAN.  Subject to adjustment as
     provided in Section 14 hereof, a total of 528,444 ("Shares") of the
     Corporation's common stock ("Common Stock") shall be subject to the Plan,
     and such amount shall be, and is hereby reserved for sale for such
     purpose.  The Shares shall consist of shares of the Corporation's Common
     Stock that are presently authorized but unissued or that were previously
     issued, reacquired and held by the Corporation as treasury shares.  Any of
     the Shares that remain unsold and that are not subject to outstanding
     options at the termination of the Plan shall cease to be reserved for the
     purpose of the Plan.  If any Option (as hereinafter defined) granted under
     the Plan shall expire or terminate for any reason without having been
     exercised in full, the Shares subject to such Option, but not purchased
     thereunder, shall be removed from the reserve.


              3.      ADMINISTRATION OF THE PLAN.
                      --------------------------

              3.1  The Plan shall be administered by a committee appointed from
     time to time by the Board of Directors of the Corporation ("Committee"). 
     The Committee shall consist of not less than two (2) members, each of
     which shall be a director of the Corporation.  Members of the Committee
     shall be eligible to receive Options under the Plan, provided that such
     members do not participate in the decision to grant options to themselves.

              3.2  Subject to the terms of the Plan, the Committee shall have
     full and final authority to determine the persons who are to be granted
     Options under the Plan, the number of Shares subject to each Option and
     the schedule by which the Options may be exercised.

              3.3  Subject to the terms of the Plan, the Committee shall also
     have complete authority to interpret the Plan, to prescribe, amend, and
     rescind rules and regulations relating to the Plan, to determine the
     details and provisions of each Option Agreement (as hereinafter defined)
     and to make all other determinations necessary or desirable in the
     administration of the Plan.
<PAGE>






              3.4  The Committee shall have the authority to grant options that
     do not qualify as incentive stock options ("Options") under Section 422 of
     the Internal Revenue Code of 1986, as amended ("Code").

              4.      ELIGIBILITY.
                      -----------

              4.1  The individuals who shall be eligible to participate in the
     Plan shall be such key employees ("Optionees") of the Corporation as the
     Committee shall determine, in its sole discretion.  In determining the
     employees to whom Options shall be granted and the number of Shares to be
     covered by each Option, the Committee may take into account the nature of
     the services rendered by the respective employees, their present and
     potential contributions to the success of the Corporation and such other
     factors as the Committee, in its sole discretion, may deem relevant. 
     Options may be granted to key employees who hold or have held options
     under previous plans.

              4.2  Except as provided herein, or in the agreement between the
     Corporation and the Optionee with respect to any particular grant of
     Options ("Option Agreement"), there is no limit on the number or value of
     Options exercisable in any one (1) year.

              5.  OPTION AGREEMENT.  The grant of each Option shall be
     evidenced by minutes of a meeting of the Committee or the unanimous
     written consent of all members of the Committee and by a written Option
     Agreement effective as of the date of the grant, which Option Agreement
     shall set forth such terms and conditions as may be determined by the
     Committee to be consistent with the Plan.

              6.  TERM AND EXERCISABILITY OF OPTION.
                  ---------------------------------

              6.1  Each Option shall commence on the date provided in the
     Option Agreement ("Date of Grant").  Except as otherwise provided in the
     Option Agreement, each Option shall terminate ten (10) years after its
     Date of Grant.  If the Optionee shall cease to be a regular full-time
     employee of the Corporation for any reason, any unexercised Options shall
     terminate three (3) months from the date of such termination of
     employment.

              6.2  Nothing in the Plan or in any Option shall confer on any
     Optionee the right to continue in the employ of the Corporation or
     interfere in any way with the right of the Corporation to terminate the
     Optionee's employment at any time.

              6.3  Unless otherwise provided in an Option Agreement, all
     Options granted hereunder shall become exercisable in three (3)
     installments, the Optionee having the right to purchase from the


                                        - 2 -
<PAGE>






     Corporation a portion of the Shares subject to the Option ("Option
     Shares") on and after the following dates on a cumulative basis:

                      (a) on and after the date that is twelve (12) months from
     the Date of Grant, up to thirty-three and one-third percent (33 1/3%) of
     the total number of Option Shares;

                      (b) on and after the date that is twenty-four (24) months
     from the Date of Grant, up to an additional thirty-three and one-third
     percent (33 1/3%) of the total number of Option Shares; and

                      (c) on and after the date that is thirty-six (36) months
     from the Date of Grant, up to an additional thirty-three and one-third
     percent (33 1/3%) of the total number of Option Shares.

              For example, if Options to acquire 1,000 Shares are granted to an
     Optionee on May 15, 1995, the Optionee would not have any right to acquire
     Shares under the Options until May 15, 1996.  From May 15, 1996 until May
     14, 1997, he would have the right to exercise thirty-three and one-third
     percent (33 1/3%) of his Options and thereby acquire 333 1/3 Shares.  From
     May 15, 1997 until May 14, 1998, he would have the right to exercise an
     additional thirty-three and one-third percent (33 1/3%) of his options for
     an additional 333 1/3 Shares; if, however, he had not previously exercised
     the Option for the initial 333 1/3 Shares, he would have a continuing
     right to exercise the initial portion of the Option Shares as well as the
     second portion, for a total of 66 2/3% or 666 2/3 Shares.

              7.  PURCHASE PRICE.  The purchase price per Share shall be set by
     the Committee.  The purchase price per Share shall be no less than par
     value per Share.

              8.      MANNER OF PAYMENT.  Options shall be exercised by
     delivery by the Optionee to the Corporation of an executed Notice of
     Exercise in the form provided by the Corporation, accompanied by either
     (i) a check in the amount of the purchase price, or (ii) by previously
     owned shares of Common Stock with a fair market value equal to the
     purchase price.

              9.      RESTRICTIONS ON SHARES.

              9.1     As soon as practicable after receipt of the purchase
     price, the Corporation shall deliver to the Optionee a certificate or
     certificates for the purchased Shares.  The Optionee shall thereupon
     become a shareholder of the Corporation with respect to the Shares
     represented by such certificates and, as such, shall be fully entitled to
     receive dividends and other distributions with respect to such Shares and
     shall have all of the other rights of a shareholder.  Notwithstanding the
     foregoing, the Optionee shall be prohibited from the sale, exchange,
     transfer, pledge, hypothecation, gift or other disposition of such Shares
     until the date on which such Shares are traded on an established

                                        - 3 -
<PAGE>






     securities exchange or secondary market; however, such Shares may be used
     as payment of the purchase price of Shares issued upon the exercise of
     other Options.  The aforesaid restriction shall apply to any new,
     additional or different securities the Optionee may receive with respect
     to such Shares by virtue of a stock split or stock dividend or any other
     change in the corporate or capital structure of the Corporation.

              9.2     At any time after termination of employment with the
     Corporation by the Optionee for any reason, including death, the
     Corporation shall have the right to repurchase all or any portion of the
     Shares acquired by such Optionee pursuant to this Plan (whether then held
     by the Optionee or by a transferee).  Such right must be exercised by the
     Corporation, if at all, at a time when the Shares are not traded on an
     established securities exchange or secondary market.  The purchase price
     for such re-acquired shares shall be the per share value most recently
     established by the Board of Directors as the fair market value of the
     Corporation's Common Stock for purposes of the grant of Options under this
     Plan.  The entire purchase price shall be paid at closing of such
     purchase, which shall occur on the date set by the Corporation within
     ninety (90) days after exercise by the Corporation of its right to
     repurchase.

              9.3     Until such time as the restrictions hereunder lapse with
     respect to the Shares, the certificates representing the Shares shall
     contain a legend evidencing such restrictions. Alternatively, the
     Corporation may require the Optionee to deposit the Share certificate(s)
     with the Corporation or its agent, endorsed in blank or accompanied by a
     duly executed irrevocable stock power or other instrument of transfer.

              10.     NON-ASSIGNABILITY OF OPTION.  During the Optionee's
     lifetime, the Option shall not be transferrable by the Optionee.

              11.     DIVIDENDS.  If at any time after an Option is granted but
     prior to its exercise, the Board of Directors shall declare, with respect
     to the Common Stock, any dividend payable in shares of stock of the
     Corporation of any class, then there shall be deliverable upon the
     subsequent exercise of any Option under this Plan, in addition to each
     Option Share granted, and for no additional price, such additional share
     or shares as shall have been distributable as a result of such share
     dividend in respect of an Option Share; except that fractional shares
     shall not be so deliverable.  Any such share dividend shall be deemed part
     of the Option Shares for the purpose of this Plan.

              12.     COMPLIANCE WITH LAWS.  Notwithstanding any other
     provisions of the Plan, each Option Agreement shall contain such
     provisions as the Committee shall determine to be appropriate to ensure
     that the Optionee agrees for himself or herself and for his or her legal
     representatives, that the Option shall not be exercisable by him, her or
     them and that the Corporation shall not be obligated to issue any Shares,
     during a time period in which such exercise would adversely affect any

                                        - 4 -
<PAGE>






     exemption from registration under applicable state and federal securities
     laws that is being relied upon, or is being considered by the Corporation
     for the issuance of any of its securities whether pursuant to the Plan or
     otherwise.

              13.     NO RIGHTS IN OPTION STOCK.  An Optionee shall not have
     any rights as a shareholder with respect to Shares for which an Option has
     not been exercised and payment has not been made as herein provided nor
     shall an Optionee have rights with respect to shares or the Corporation's
     stock not expressly conferred by the Plan.

              14.     ADJUSTMENTS.  If there are any changes in the
     capitalization of the Corporation affecting in any manner the number or
     kind of outstanding shares of the Corporation's stock, whether such
     changes have been occasioned by recapitalization, reorganization or other
     changes in the Corporation's capital structure or its business, merger or
     consolidation of the Corporation, issuance of bonds, debentures, preferred
     or prior preference stocks ahead of or affecting the Common Stock or the
     rights thereof, dissolution or liquidation of the Corporation, or any sale
     or transfer of all or any part of its assets or business, or any other
     corporate act or proceedings, whether of a similar character or otherwise,
     then the number and kinds of shares of the Corporation's stock then
     subject to Options and the price to be paid therefor shall be
     appropriately adjusted by the Committee.

              15.     AMENDMENT AND TERMINATION.  Unless the Plan has been
     terminated as hereinafter provided, it shall terminate on the date that is
     ten (10) years after the date of adoption hereof, except as to Options
     previously granted and outstanding under the Plan at such date, and no
     Options shall be granted hereunder after such date.  The Plan may be
     terminated, modified, or amended by the shareholders of the Corporation. 
     The Board of Directors of the Corporation may terminate the Plan or make
     such modifications or amendment thereof as it shall deem advisable or in
     order to conform to any change in any law or regulation applicable
     thereto; provided, however, that the Board of Directors may not, without
     further approval by the holders of a majority of the outstanding shares of
     the Corporation having general voting power; (a) increase the maximum
     number of shares as to which Options may be granted under the Plan, (b)
     change the class of employees eligible to be granted Options, (c) increase
     the periods during which Options may be granted or exercised, or (d)
     provide for the administration of the Plan otherwise than by the
     Committee.  No termination, modification, or amendment of the Plan may,
     without the consent of the employee to which any Option shall theretofore
     have been granted, adversely affect the rights of each such employee under
     such Option.

           delivers the  amount of  cash (or other  consideration determined  by
           the Board to  be acceptable  to the  Company, pursuant  to the  Plan)

                                    Administration

           2.1   The Plan  shall be administered by the  Committee.  Each member
     of  the Committee shall be appointed by and  shall serve at the pleasure of
     the Board.  The  Board shall have the sole continuing authority  to appoint
     members  of  the Committee  both  in  substitution  for members  previously
     appointed and to fill vacancies  however caused.  The  following provisions
     shall apply to the administration of the Plan:

                  (a)    The Committee  shall  designate one  of its  members as
           Chairman and shall hold  meetings at such times and places as it  may
           determine.    Each member  of  the  Committee  shall  be notified  in
           writing of  the time  and place  of any  meeting of the  Committee at
           least two days prior  to such meeting, provided  that such notice may
           be waived by  a Committee member.  A  majority of the members of  the
           Committee shall  constitute  a quorum,  and  any  action taken  by  a
           majority of the members  of the Committee present at any duly  called

                                          3
<PAGE>






           meeting  at  which  a  quorum  is  present  (as  well as  any  action
           unanimously  approved in  writing)  shall constitute  action  by  the
           Committee.   The Committee  may act  by unanimous  written consent of
           its members.

                  (b)   The Committee may appoint a Secretary (who need not be a
           member of  the Committee)  who shall  keep minutes  of its  meetings.
           The Committee may make such rules and regulations  for the conduct of
           its business as it may determine.

                  (c)   The Committee  shall have full and  exclusive authority,
           subject to the express provisions  of the Plan, to interpret the Plan
           as it relates to  Options granted or to be granted to Optionees under
           the  Plan,  to  provide,  modify and  rescind  rules  and regulations
           relating  thereto,  to determine  the  terms  and provisions  of each
           Option  granted to Optionees  and the  form of  each option agreement
           evidencing an  Option granted  to Optionees  under the  Plan, and  to
           make  all  other  determinations  and  perform such  actions  as  the
           Committee deems necessary or advisable to  administer the Plan as  it
           relates to Options  granted or to be  granted to Optionees under  the
           Plan.  In addition, the Committee  shall have full authority, subject
           to the express  provisions of the Plan,  to determine to whom Options
           shall be granted,  the time or date of grant of each such Option, the
           number of shares subject thereto and the  price at which such  shares
           may be purchased.  In making  such determinations, the Committee  may
           take  into  account  the  nature  of  the  services  rendered  by the
           Optionees, his  or  her present  and potential  contributions to  the
           success  of the Corporation's  business and  such other  facts as the
           Committee in its discretion shall deem  appropriate to carry out  the
           purposes of the Plan.

                  (d)  No  member of the Committee or the  Board shall be liable
           for  any  action taken  or  determination  made  in  good faith  with
           respect to the Plan or any Option granted hereunder.

                                     ARTICLE III

                                   Grant of Options

     person's name.  Any person who has been granted Options under this  Article
     III may  decline to  accept such  Options.   Such person  may indicate  his
     election to decline to accept the Options  by giving notice thereof to  the
     Corporation or by  refusing to execute a stock option agreement relating to
     the Options.

           3.2    PRICE.  The purchase price per share of Restricted Stock under

<PAGE>






                  (a)   Notwithstanding   anything   contained  herein   to  the
           contrary  or  in  any  option  agreement   executed  by  and  between
           Corporation and any Optionee, each Option granted under this  Article
           III  shall be fully  exercisable during  the period  beginning on the
           Date of Grant and ending on the Expiration Date.  

                  (b)   Notwithstanding   anything   contained  herein   to  the
           contrary  or  in  any  option  agreement  executed  by  and   between
           Corporation,   all  obligations   to  an   Optionee  hereunder  shall
           terminate in  the  event of  the  Termination  of Employment  of  the
           Optionee with the  Corporation, for any reason whatsoever,  including
           but not  limited  to the  death,  disability,  or retirement  of  the
           Optionee, prior to the purchase and sale  of the shares of Restricted
           Stock hereunder.    Any  unexercised Option  granted to  an  Optionee
           under  this  Article  III  shall  expire  and  become  null  and void
           immediately upon the Optionee's Termination of Employment.  

                  (c)   Under  the provisions of any option agreement evidencing
           an Option  granted hereunder, the Committee  or the  Board may impose
           such other  terms and conditions  upon the exercise  of an Option  as
           are not inconsistent with the terms of the Plan.


                                     ARTICLE IV

                                    Miscellaneous

           4.1    ADJUSTMENTS  TO REFLECT  CAPITAL AND  OTHER CORPORATE CHANGES.
     The Options  and the exercise price for such Options shall be appropriately
     adjusted  to  reflect  any stock  dividend,  stock  split,  combination  or
     exchange  of  shares,  recapitalization,  merger,  consolidation  or  other
     change  in  capitalization  with  a  similar  substantive effect  upon  the
     Options  granted   hereunder.     After  any   reorganization,  merger   or
     consolidation in which  the Corporation is not  the surviving  corporation,
     Optionee  shall, at no  additional cost, be  entitled upon  the exercise of
     the Options  to receive (subject  to any required  action by shareholders),
     in lieu  of the number  of shares of  Restricted Stock receivable  pursuant
     hereto, the  number and  class of shares  of stock  or other securities  to
     which  Optionee  would have  been  entitled pursuant  to the  terms  of the
     reorganization,   merger  or   consolidation  if,  at   the  time  of  such
     reorganization, merger or  consolidation, Optionee  had been the  holder of
     record of  a number  of  shares of  stock  equal to  the number  of  shares
     receivable or exercisable pursuant  hereto.  Comparable rights shall accrue
     to  Optionee  in  the  event  of  successive  reorganizations,  mergers  or
     consolidations of the character described above.

           In the event  of a reclassification  of Common Stock  not covered  by
     the  foregoing,  or  in  the  event  of  a  liquidation  or  reorganization
     (including a merger, consolidation or  sale of assets) of  the Corporation,
     the Board shall make  such adjustments, if any, as it may  deem appropriate
     in  the   number,  purchase  price  and  kind  of  shares  covered  by  the
     unexercised portions  of the  Options theretofore granted  under the  Plan.
     The provisions of  this Section 4.1 shall  only be applicable if,  and only

                                          5
<PAGE>






     to the extent  that, the  application thereof  does not  conflict with  any
     valid governmental statute, regulation, or rule.

           4.2    AMENDMENT AND TERMINATION OF THE  PLAN.  Subject to the  right
     of the Board  to terminate the  Plan prior thereto and  extend the term  of
     the Plan,  the Plan shall terminate on January 1, 1997.   No Options may be
     granted after termination of the Plan.  The Board may at  any time alter or
     amend the  Plan but  the Board  may not  make any  alteration or  amendment
     thereof  which   operates  to   (i)  abolish  the   Committee,  change  the
     qualifications of its members, or  withdraw the administration of  the Plan
     from  its  supervision,  (ii)  increase  the  total  number  of  shares  of
     Restricted  Stock  which may  be  granted  under the  Plan  (other  than as
     provided in Section  4.1 of this Article IV), (iii)  extend the term of the
     Plan or  the maximum exercise periods provided in  Article III hereof, (iv)
     decrease the minimum  purchase price for  Restricted Stock  under the  Plan
     (other than as provided in Section 4.1 of this Article IV), (v)  materially
     increase the  benefits accruing  to participants  under the  Plan, or  (vi)
     materially  modify the requirements as  to eligibility for participation in
     the Plan.

           No termination  or amendment of the  Plan shall  adversely affect the
     rights  of an Optionee  under an  Option, except  with the consent  of such
     Optionee.

           4.3   NO FRACTIONAL SHARES.   Notwithstanding any contrary indication
     in the Plan or  in any option agreement evidencing an Option  granted under
     the  Plan, no fractional  shares of Restricted Stock  may be purchased upon
     exercise of any Option.

           4.4    LEGEND.  Each  certificate for  the shares  of the  Restricted
     Stock issued hereunder  or in substitution  or exchange  therefor, or  upon
     the transfer thereof, together with  any other Restricted Stock  subject to
     the restrictions  of this  Plan, shall  be stamped  or otherwise  imprinted
     with the legend in substantially the following form:

                  The transfer of this instrument or  the securities
                  evidenced hereby  is restricted under the terms of
                  the 1996 Non-Statutory Stock Option Plan  dated as
                  of April 22, 1996,  a copy of which  is on file at
                  the  principal  office  of  Virtual  Open  Network
                  Environment Corporation,  and no transfer of  this
                  instrument  or such securities shall be made until
                  the conditions thereof shall have been fulfilled.

           4.5    LAPSE  OF RESTRICTIONS.   The  restrictions on  each share  of
     Restricted Stock  as described in this  Plan and Exhibit  A attached hereto
     shall lapse One Hundred Eighty (180) days after  any public offering of the
     Corporation's stock.

           4.6      PAYMENT  OF  PURCHASE  PRICE; APPLICATION  OF  FUNDS.   Upon
     exercise of an Option,  the purchase price shall be paid in  full by check;
     provided, however, that at  the request  of an Optionee  and to the  extent
     permitted by applicable law, the Corporation may,  in its sole and absolute

                                          6
<PAGE>






     discretion, approve  reasonable arrangements  with one  or more  Optionees,
     under which such  an Optionee may exercise  an Option by delivering  to the
     Corporation an  irrevocable notice  of exercise,  together with such  other
     documents  as  the Corporation  shall require,  and the  Corporation shall,
     upon receipt  of full  payment by  check, or  any other reasonable  payment
     arrangement, of the purchase  price and any other amounts due in respect of
     such   exercise,  deliver  to  such  Optionee   one  or  more  certificates
     representing  the shares  of  Restricted Stock  issued  in respect  of such
     exercise.  The proceeds  of any sale of Restricted Stock covered by Options
     shall  constitute general  funds of the  Corporation.  Upon  exercise of an
     Option,  the  Optionee  will  be  required  to  pay, or  arrange  with  the
     Corporation for the payment  of, the amount of any federal, state, or local
     taxes  required by law to be withheld in connection with such exercise.  No
     shares  of Restricted  Stock shall  be issued  upon exercise  of  an Option
     until full payment therefor  has been made, and an Optionee shall have none
     of the rights of a stockholder until shares are issued to him.

           4.7   REQUIREMENTS  OF LAW.  The granting of Options and the issuance
     of Restricted Stock upon the  exercise of an Option shall be subject to all
     applicable  laws,   rules  and  regulations,  and   to  such   approval  by
     governmental agencies as may be required.

           4.8    NONTRANSFERABILITY OF  OPTIONS.   An Option granted  under the
     Plan  shall not be  transferable by the  Optionee and  shall be exercisable
     during the lifetime of the Optionee only by the Optionee.

           4.9   OPTION AGREEMENT; INVESTMENT LETTER.  

                  (a)   Each  person  who  accepts  an  Option  offered  to  him
           hereunder  shall enter  into an  agreement with  the Corporation,  in
           such  form as the  Committee may  prescribe, setting  forth the terms
           and conditions  of the Option, whereupon  such person  shall become a
           participant in the Plan.

                  (b)   The  Corporation's  obligation  to   deliver  Restricted
           Stock  with  respect to  an  Option  shall  be  conditioned upon  its
           receipt from  the Optionee, to  whom such Restricted  Stock is to  be
           delivered,  of   an  executed  investment   letter  containing   such
           representations and agreements  as the Committee may determine to  be
           necessary or  advisable in order to  enable the  Corporation to issue
           and  deliver such  Restricted  Stock to  such Optionee  in compliance
           with applicable federal, state, or  local securities laws,  rules, or
           regulations.

           4.10  EFFECTIVE DATE OF THE PLAN.   The Plan shall become  effective,
     as of  the date  of its  adoption by  the Board.   If  the Plan  is not  so
     adopted, the Plan shall terminate  and all Options granted  hereunder shall
     be null and void.

           4.11   TERMINATION OF  EMPLOYMENT.   A transfer  of employment within
     the Corporation shall not be  considered to be a Termination  of Employment
     for  the purposes  of the  Plan.   Nothing in  the  Plan or  in any  option
     agreement evidencing an Option granted under the  Plan to an Optionee shall

                                          7
<PAGE>






     confer  upon  any Optionee  any  right to  continue  in the  employ  of the
     Corporation or in  any way interfere with  the right of the  Corporation to
     terminate the employment  or contractual relationship with the  Optionee at
     any time, with or without cause.

           4.12  CONSTRUCTION.   Options granted under the Plan are not intended
     to be treated as  incentive stock  options under Section  422 of the  Code.

     other gender, unless the context requires otherwise.

           4.13   INTERPRETATION.   The  section  headings  hereof are  inserted
     solely for  convenience  of reference  only  and  shall be  disregarded  in

     hereof, shall be interpreted  and construed in accordance with the  laws of
     the  State of Delaware,  except for its rules  relating to  the conflict of
     laws;  provided,  however,  that  such terms  and  provisions  relating  to
     federal income tax  law shall be  interpreted and  construed in  accordance
     with  federal  law,  and  such   terms  and  provisions  relating   to  the
     application of  securities  laws  shall be  interpreted  and  construed  in
     accordance  with federal  law and  the laws  of the  jurisdiction in  which
     Optionee resides or is domiciled.

           4.15   SEVERABILITY.  If any  provision, or portion  thereof, of this
     Plan, or the application  thereof to any person or circumstances, shall, to
     any extent  be  invalid or  unenforceable,  the  remainder hereof,  or  the
     application of such provision, or  portion thereof, to any other person  or

     defined) and its Subsidiaries (as hereinafter defined), if any, by
     encouraging and providing for the acquisition of an equity interest in the
     Company by non-employee directors, key employees and consultants through
     the grant of awards with respect to shares of Common Stock (as hereinafter
     defined).  The Plan will enable the Company to retain the services of non-
     employee directors, key employees and consultants upon whose judgment,
     interest, and special effort the successful conduct of its operations is
     largely dependent and to compete effectively with other enterprises for
     the services of non-employee directors, key employees and consultants as
     may be needed for the continued improvement of its business.

              1.02  Adoption and Term.  The Plan shall become effective on June
     12, 1996 ("Effective Date"), subject to the prior approval of a simple
     majority of the holders of Voting Stock (as hereinafter defined)
     represented, by person or by proxy, and entitled to vote at an annual or
     special meeting of the holders of Voting Stock.  The Plan shall terminate
     on June 11, 2006, or such earlier date as shall be determined by the Board
     (as hereinafter defined).

              nominated for election as members of the Board by the
              Board (or a committee of the Board) at a time when the

              persons who were members of the Board on the Effective
              Date; provided, however, that any persons nominated for

     and absolute discretion.
      
              2.14  Disability Date means the date which is six months after

     national securities exchange, the closing sales price or, if none, the
     average of the bid and asked prices of the Common Stock on such date as
     reported on the National Association of Securities Dealers Automated
     Quotation System ("Nasdaq"); provided, however, that, if there were no
     sales reported as of such date, Fair Market Value shall be computed as of

     day on which Fair Market Value is to be determined, Fair Market Value
     shall be determined as of the first date immediately preceding such date
     on which such exchange or quotation system was open for trading.  In the
     event the Common Stock is not admitted to trade on a securities exchange
     or quoted on Nasdaq, the Fair Market Value of a share of Common Stock as
     of any given date shall be as determined in good faith by the Committee,
     which determination may be based on, among other things, the opinion of

     Article IV.  Shares of Common Stock

              4.01  Number of Shares of Common Stock Issuable.  Subject to
     adjustments as provided in Section 9.05, 3,500,000 shares of Common Stock
     shall be available for Awards under the Plan.  The Common Stock to be
     offered under the Plan shall be authorized and unissued Common Stock, or
     issued Common Stock that shall have been reacquired by the Company and
     held in its treasury.

              4.02     Calculation of Number of Shares of Common Stock Awarded
     to any Participant.  In the event the purchase price of an Option is paid,
     or tax or withholding payments relating to an Award are satisfied, in
     whole or in part through the delivery of shares of Common Stock, a
     Participant will be deemed to have received an Award with respect to those
     shares of Common Stock. 

              4.03  Shares of Common Stock Subject to Terminated Awards.  The
     Common Stock covered by any unexercised portions of terminated Options,
     shares of Common Stock forfeited as provided in Section 7.02(a) and shares
     of Common Stock subject to Awards that are otherwise surrendered by the
     Participant without receiving any payment or other benefit with respect
     thereto may again be subject to new Awards under the Plan.

     Article V.  Participation

              5.01  Eligible Participants.  Participants in the Plan shall
     include such officers, other key employees of and consultants to the
     Company or its Subsidiaries, whether or not directors of the Company, as
     the Committee, in its sole discretion, may designate from time to time. 
     In making such designation, the Committee may take into account the nature
     of the services rendered by the officers, key employees and consultants,
     their present and potential contributions to the success of the Company,
     and such other factors as the Committee, in its discretion, may deem
     relevant.  The Committee's designation of a Participant in any year shall
     not require the Committee to designate such person to receive Awards in
     any other year.  The Committee shall consider such factors as it deems
     pertinent in selecting Participants and in determining the type and amount
     of their respective Awards.  A Participant may hold more than one Award
     granted under the Plan.  During the term of the Plan, no Employee
     Participant may receive Awards with respect to more than 750,000 shares of
     Common Stock.

              Non-Employee Directors shall receive Non-Employee Director
     Options in accordance with Article VIII, the provisions of which are
     automatic and non-discretionary in operation.  Non-Employee Directors
     shall not be eligible to receive any other Awards under the Plan unless
     they are no longer Non-Employee Directors on the Date of Grant of such
     Awards.

     Article VI.  Stock Options

              6.01  Grant of Option.  Any Option granted under this Article VI
     shall have such terms as the Committee may, from time to time, approve,
     and the terms and conditions of Options need not be the same with respect
     to each Participant.  Under this Article VI, the Committee may grant to
     any Employee or Consultant Participant one or more Incentive Stock
     Options, Non-Qualified Stock Options or both types of Options; provided,
     however, that Incentive Stock Options may only be granted to Employee
     Participants.  To the extent any Option does not qualify as an Incentive
     Stock Option (whether because of its provisions, the time or manner of its
     exercise or otherwise), that Option or the portion thereof that does not
     so qualify shall constitute a separate Non-Qualified Stock Option.

              6.02  Incentive Stock Options.  In the case of any grant of an
     Incentive Stock Option, whenever possible, each provision hereof and in
     any Award Agreement relating to such Option shall be interpreted to
     entitle the holder thereof to the tax treatment afforded by Section 422 of
     the Code, except in connection with the exercise of Options following a
     Participant's Termination of Employment, except in accordance with a
     specific determination of the Committee with the consent of the affected
     Participant and except to the extent that the operation of Section 9.05
     would cause an Option to no longer be entitled to such treatment.  If any
     provision hereof or that Award Agreement is held not to comply with
     requirements necessary to entitle that Option to that tax treatment, then
     except as otherwise provided in the preceding sentence: (a) that provision
     shall be deemed to have contained from the outset such language as is
     necessary to entitle the Option to the tax treatment afforded under
     Section 422 of the Code; and (b) all other provisions hereof and of that
     Award Agreement remain in full force and effect.  Except as otherwise
     specified in the first sentence of this Section 6.02, if any Award
     Agreement covering an Option the Committee designates to be an Incentive
     Stock Option hereunder does not explicitly include any term required to
     entitle that Incentive Stock Option to the tax treatment afforded by
     Section 422 of the Code, all such terms shall be deemed implicit in the
     designation of that Option, and that Option shall be deemed to have been
     granted subject to all such terms.
       
              6.03  Terms of Options.  Options granted under this Article VI
     shall be subject to the following terms and conditions and shall be in
     such form and contain such additional terms and conditions, not
     inconsistent with the terms of the Plan, as the Committee shall deem
     desirable:

                      (a)  Option Price.  The option price per share of
              Common Stock purchasable under an Option shall be
              determined by the Committee at the time of grant but, if
              the Option is an Incentive Stock Option, the option price
              per share shall not be less than 100% of the Fair Market
              Value of a share of Common Stock on the Date of Grant;
              provided, however, that, if an Incentive Stock Option is
              granted to a Ten Percent Shareholder, the option price

                                        - 8 -
<PAGE>






              per share shall be at least 110% of the Fair Market Value
              of a share of Common Stock on the Date of Grant.

                      (b)  Option Term.  The term of each Option shall
              be fixed by the Committee, but no Option shall be
              exercisable more than ten years after its Date of Grant;
              provided, however, that, if an Incentive Stock Option is
              granted to a Ten Percent Shareholder, the Option shall
              not be exercisable more than five years after its Date of
              Grant.

                      (c)  Exercisability.  An Award Agreement with
              respect to Options may contain such performance targets,
              waiting periods, exercise dates, restrictions on exercise
              (including, but not limited to, a requirement that an
              Option is exercisable in periodic installments), and
              restrictions on the transfer of the underlying shares of
              Common Stock, if any, as may be determined by the
              Committee at the time of grant.  To the extent not
              exercised, installments shall cumulate and be
              exercisable, in whole or in part, at any time after
              becoming exercisable, subject to the limitations set
              forth in Sections 6.03(b) and (h).  If an Option is an
              Incentive Stock Option and if required by Section 422 of
              the Code, the aggregate Fair Market Value of the shares
              of Common Stock underlying such Option (determined at the
              time the Option is granted) that becomes exercisable in
              any one calendar year shall not exceed $100,000. 

                      (d)  Method of Exercise.  Subject to whatever
              installment exercise and waiting period provisions that
              apply under Section 6.03(c) above, Options may be
              exercised in whole or in part at any time during the term
              of the Option, by giving written notice of exercise to
              the Company specifying the number of shares of Common
              Stock to be purchased.  Such notice shall be accompanied
              by payment in full of the purchase price in such form as
              the Committee may accept (including payment in accordance
              with a cashless exercise program approved by the
              Committee).  If and to the extent the Committee
              determines in its sole discretion at or after grant,
              payment in full or in part may also be made in the form
              of shares of Common Stock already owned by the
              Participant (and for which the Participant has good
              title, free and clear of any liens or encumbrances) based
              on the Fair Market Value of the shares of Common Stock on
              the date the Option is exercised; provided, however, that
              the right to make payment of the purchase price of an
              Incentive Stock Option in the form of already owned
              shares may be authorized only at the time of grant.  Any
              already owned Common Stock used for payment must have
              been held by the Participant for at least six months.  No

                                        - 9 -
<PAGE>






              Common Stock shall be issued on exercise of an Option
              until payment, as provided herein, therefor has been
              made.  A Participant shall generally have the right to
              dividends or other rights of a stockholder with respect
              to Common Stock subject to the Option only when
              certificates for shares of Common Stock are issued to the
              Participant.  
       
                      (e)      Reload Options.  The Committee shall have the
              authority to specify, at the time of grant or, with respect to
              Non-Qualified Stock Options, at or after the time of grant, that
              an Employee or a Consultant Participant shall be granted a Non-
              Qualified Stock Option (a "Reload Option") in the event such
              Participant exercises all or a part of an Option (an "Original
              Option") by surrendering in accordance with Section 6.03(d) of
              the Plan already owned shares of Common Stock in full or partial
              payment of the purchase price under the Original Option, subject
              to the availability of shares of Common Stock under the Plan at
              the time of such exercise; provided, however, that no Reload
              Option shall be granted to a Non-Employee Director.  Each Reload
              Option shall cover a number of shares of Common Stock equal to
              the number of shares of Common Stock surrendered in payment of
              the purchase price under such Original Option, shall have a
              purchase price per share of Common Stock equal to the 100% of the
              Fair Market Value of a share of Common Stock on the Date of Grant
              of such Reload Option, and shall expire on the stated expiration
              date of the Original Option.  A Reload Option shall be
              exercisable at any time and from time to time after the time of
              grant of such Reload Option (or, as the Committee in its sole
              discretion shall determine at or after the time of grant, at such
              time or times as shall be specified in the Reload Option).  Any
              Reload Option may provide for the grant, when exercised, of
              subsequent Reload Options to the extent and upon such terms and
              conditions, consistent with this Section 6.03(e), as the
              Committee in its sole discretion shall specify at or after the
              Date of Grant of such Reload Option.  A Reload Option shall
              contain such other terms and conditions, which may include a
              restriction on the transferability of the shares of Common Stock
              received upon exercise of the Original Option representing at
              least the after-tax profit received upon exercise of the Original
              Option, as the Committee in its sole discretion shall deem
              desirable, and which may be set forth in rules or guidelines
              adopted by the Committee or in the Award Agreements evidencing
              the Reload Options.

                      (f)  Non-Transferability of Options.  No Option
              shall be transferable by the Participant otherwise than
              by will or the laws of descent and distribution.  

                      (g)  Acceleration or Extension of Exercise Time. 
              The Committee, in its sole discretion, shall have the
              right (but shall not in any case be obligated) to permit

                                        - 10 -
<PAGE>






              purchase of Common Stock subject to any Option granted to
              an Employee or a Consultant Participant prior to the time
              such Option would otherwise become exercisable under the
              terms of the Award Agreement.  In addition, the
              Committee, in its sole discretion, shall have the right
              (but shall not in any case be obligated) to permit any
              Option granted to an Employee or a Consultant Participant
              to be exercised after its expiration date, subject,
              however to the limitation set forth in Section 6.03(b).

                      (h)  Exercise of Options Upon Termination of
              Employment.

                               (i)  Exercise of Vested Options
                      Upon Termination of Employment.

                                       (A)  Termination. 
                               Unless the Committee, in its
                               sole discretion, provides for a
                               shorter or longer period of time
                               in the Award Agreement or a
                               longer period of time in
                               accordance with Section 6.03(g),
                               upon an Employee or a Consultant
                               Participant's Termination of
                               Employment other than by reason
                               of death or Disability, an
                               Employee or a Consultant
                               Participant may, within three
                               months from the date of such
                               Termination of Employment,
                               exercise all or any part of his
                               or her Options as were
                               exercisable on the date of
                               Termination of Employment if
                               such Termination of Employment
                               is not for Cause.  If such
                               Termination of Employment is for
                               Cause, the right of the Employee
                               or Consultant Participant to
                               exercise such Options shall
                               terminate on the date of
                               Termination of Employment.  In
                               no event, however, may any
                               Option be exercised later than
                               the date determined pursuant to

                               Participant may, within one year
                               after the Disability Date,

                               her Options, whether or not such
                               Option was exercisable on the

                               Option be exercised later than
                               the date determined pursuant to
                               Section 6.03(b).

                                       (C)  Death.  Unless the

                               discretion, provides for a
                               shorter or longer period of time
                               in the Award Agreement or a

                               Participant while employed by
                               the Company, the right of the
                               Employee or Consultant
                               Participant's Beneficiary to

                               Employee or Consultant

                               of one year from the date of the
                               Employee or Consultant
                               Participant's death or on the

                               6.03(b), whichever is earlier.

                      or any part of an Option granted to an

                      not exercisable as of the date of
                      Termination of Employment, such right
                      shall expire at the date of such
                      Termination of Employment. 
                      Notwithstanding the foregoing, the
                      Committee, in its sole discretion and
                      under such terms as it deems
                      appropriate, may permit an Employee or a
                      Consultant Participant who will continue
                      to render significant services to the
                      Company after his or her Termination of
                      Employment to continue to accrue service
                      with respect to the right to exercise
                      his or her Options during the period in
                      which the individual continues to render
                      such services.

     Article VII.  Restricted Shares

              7.01  Restricted Share Awards.  Restricted Shares may be issued
     either alone or in addition to other Awards granted under the Plan.  The
     Committee may grant to any Employee or Consultant Participant an Award of
     shares of Common Stock in such number, and subject to such terms and
     conditions relating to forfeitability and restrictions on delivery and
     transfer (whether based on performance standards, periods of service or
     otherwise) as the Committee shall establish.  The terms of any Restricted
     Share Award granted under the Plan shall be set forth in an Award
     Agreement, which shall contain provisions determined by the Committee and
     not inconsistent with the Plan.  The provisions of Restricted Share Awards
     need not be the same for each Participant receiving such Awards.

                      (a)      Issuance of Restricted Shares.  As soon as
              practicable after the Date of Grant of a Restricted Share Award
              by the Committee, the Company shall cause to be transferred on
              the books of the Company shares of Common Stock, registered on
              behalf of the Participant in nominee form, evidencing the
              Restricted Shares covered by the Award, but subject to forfeiture
              to the Company retroactive to the Date of Grant if an Award
              Agreement delivered to the Participant by the Company with
              respect to the Restricted Shares covered by the Award is not duly
              executed by the Participant and timely returned to the Company. 
              Each Participant, as a condition to the receipt of a Restricted
              Share Award, shall pay to the Company in cash the par value of a
              share of Common Stock multiplied by the number of shares of
              Common Stock covered by such Restricted Share Award.  All shares
              of Common Stock covered by Awards under this Article VII shall be
              subject to the restrictions, terms and conditions contained in
              the Plan and the Award Agreement entered into by and between the
              Company and the Participant.  Until the lapse or release of all
              restrictions applicable to an Award of Restricted Shares, the
              stock certificates representing such Restricted Shares shall be
              held in custody by the Company or its designee.  Upon the lapse

                                        - 13 -

              or release of all restrictions with respect to an Award as
              described in Section 7.01(d), one or more stock certificates,
              registered in the name of the Participant, for an appropriate
              number of shares of Common Stock as provided in Section 7.01(d),
              free of any restrictions set forth in the Plan and the Award
              Agreement, shall be delivered to the Participant.

                      (b)      Shareholder Rights.  Beginning on the Date of
              Grant of the Restricted Share Award and subject to execution of
              the Award Agreement as provided in Section 7.01(a), the
              Participant shall become a shareholder of the Company with
              respect to all shares of Common Stock subject to the Award
              Agreement and shall have all of the rights of a shareholder,
              including, but not limited to, the right to vote such shares of
              Common Stock and, except as otherwise determined by the Committee
              and specified in the applicable Award Agreement, the right to
              receive dividends (or dividend equivalents); provided, however,
              that any shares of Common Stock distributed as a dividend or
              otherwise with respect to any Restricted Shares as to which the
              restrictions have not yet lapsed shall be subject to the same
              restrictions as such Restricted Shares and shall be held in
              custody by the Company as prescribed in Section 7.01(a).

                      (c)      Restriction on Transferability.  None of the
              Restricted Shares may be assigned or transferred (other than by
              will or the laws of descent and distribution), pledged or sold
              prior to lapse or release of the restrictions applicable thereto.

                      (d)      Delivery of Shares of Common Stock Upon Release
              of Restrictions.  Upon expiration or earlier termination of the
              forfeiture period without a forfeiture and the satisfaction of or
              release from any other conditions prescribed by the Committee,
              the restrictions applicable to the Restricted Shares shall lapse. 
              As promptly as administratively feasible thereafter, subject to
              the requirements of Section 9.04, the Company shall deliver to
              the Participant or, in case of the Participant's death, to the
              Participant's Beneficiary, one or more stock certificates for the
              appropriate number of shares of Common Stock, free of all such
              restrictions, except for any restrictions that may be imposed by
              law.

              7.02  Terms of Restricted Shares.

                      (a)      Forfeiture of Restricted Shares.  Subject to
              Section 7.02(b), all Restricted Shares shall be forfeited and
              returned to the Company and all rights of the Participant with
              respect to such Restricted Shares shall terminate unless the
              Participant continues in the service of the Company or any
              Subsidiary of the Company as an employee or consultant, as the
              case may be, until the expiration of the forfeiture period for
              such Restricted Shares and satisfies any and all other conditions
              set forth in the Award Agreement.  The Committee, in its sole

                                        - 14 -
<PAGE>






              discretion, shall determine the forfeiture period (which may, but
              need not, lapse in installments) and any other terms and
              conditions applicable with respect to any Restricted Share Award.

                      (b)      Waiver of Forfeiture Period.  Notwithstanding
              anything contained in this Article VII to the contrary, the
              Committee may, in its sole discretion, waive the forfeiture
              period and any other conditions set forth in any Award Agreement
              under appropriate circumstances (including the death, Disability
              or retirement of the Participant or a material change in
              circumstances arising after the date of an Award) and subject to
              such terms and conditions (including forfeiture of a
              proportionate number of Restricted Shares) as the Committee shall
              deem appropriate, provided that the Participant shall at that
              time have completed at least one year of employment or service as
              a consultant after the Date of Grant.

     Article VIII.  Non-Employee Director Options

              8.01  Grant of Non-Employee Director Options.  On the date a Non-
     Employee Director is elected as such for the first time by the holders of
     Voting Stock, such person shall be granted a Non-Employee Director Option
     consisting of an Option to purchase 10,000 shares of Common Stock;
     provided, however, that Non-Employee Directors who are first elected as
     such by the holders of Voting Stock prior to the 1996 annual meeting of
     holders of Voting Stock shall not be entitled to receive a Non-Employee
     Director Option under this Article VIII.  The option price for such Non-
     Employee Director Options shall be the Fair Market Value of a share of
     Common Stock on the Date of Grant.  All such Options shall be designated
     as Non-Qualified Stock Options and shall have a five year term.  Each such
     Option shall be exercisable in full on the Date of Grant of such Option.

              If a Non-Employee Director's service with the Company terminates
     by reason of death, any Option held by such Non-Employee Director may be
     exercised for a period of one year from the date of death or until the
     expiration of the Option, whichever is shorter. If a Non-Employee
     Director's service with the Company terminates other than by reason of
     death, any Option held by such Non-Employee Director may be exercised for
     a period of three months from the date of such termination, or until the
     expiration of the stated term of the Option, whichever is shorter.  All
     applicable provisions of the Plan (other than Sections 6.03(g) and (h))
     not inconsistent with this Section 8.01 shall apply to Options granted to
     Non-Employee Directors.

              Article IX.  Terms Applicable to All Awards Granted Under the
     Plan

              9.01  Award Agreement.  No person shall have any rights under any
     Award granted under the Plan unless and until the Company and the
     Participant to whom such Award shall have been granted shall have executed
     and delivered an Award Agreement authorized by the Committee expressly


                                        - 15 -
<PAGE>






     granting the Award to such person and containing provisions setting forth
     the terms of the Award.  

              9.02  Plan Provisions Control Award Terms.  The terms of the Plan
     shall govern all Awards granted under the Plan, and in no event shall the
     Committee have the power to grant to a Participant any Award under the
     Plan that is contrary to any provisions of the Plan.  If any provision of
     any Award shall conflict with any of the terms in the Plan as constituted
     on the Date of Grant of such Award, the terms in the Plan as constituted
     on the Date of Grant of such Award shall control.

              9.03  Modification of Award After Grant.  Except as provided by
     the Committee, in its sole discretion, in the Award Agreement or as
     provided in Section 9.05, no Award granted under the Plan to a Participant
     may be modified (unless such modification does not materially decrease the
     value of the Award) after the Date of Grant except by express written
     agreement between the Company and the Participant, provided that any such
     change (a) shall not be inconsistent with the terms of the Plan, and (b)
     shall be approved by the Committee.

              9.04  Taxes.  The Company shall be entitled, if the Committee
     deems it necessary or desirable, to withhold (or secure payment from the
     Participant in lieu of withholding) the amount of any withholding or other
     tax required by law to be withheld or paid by the Company with respect to
     any Award.  The Company may defer issuance of Common Stock under an Award
     unless indemnified to its satisfaction against any liability for any such
     tax.  The amount of such withholding or tax payment shall be determined by
     the Committee or its delegate and shall be payable by the Participant at
     such time as the Committee determines.  A Participant shall be permitted
     to satisfy his or her tax or withholding obligation by (a) having cash
     withheld from the Participant's salary or other compensation payable by
     the Company, (b) the payment of cash by the Participant to the Company,
     (c) the payment in shares of Common Stock already owned by the Participant
     valued at Fair Market Value, and/or (d) the withholding from the Award, at
     the appropriate time, of a number of shares of Common Stock sufficient,
     based upon the Fair Market Value of such Common Stock, to satisfy such tax
     or withholding requirements.  The Committee shall be authorized, in its
     sole discretion, to establish rules and procedures relating to any such
     withholding methods it deems necessary or appropriate (including, without
     limitation, rules and procedures relating to elections by Participants who
     are subject to the provisions of Section 16 of the Exchange Act to have
     shares of Common Stock withheld from an Award to meet those withholding
     obligations).

              9.05  Adjustments to Reflect Capital Changes; Change in Control.

                      (a)  Recapitalization.  The number and kind of
              shares subject to outstanding Awards, the purchase price
              or exercise price of such Awards, the amount of Non-
              Employee Director Options to be granted on any date under
              Article VIII, and the number and kind of shares available
              for Awards subsequently granted under the Plan shall be

                                        - 16 -
<PAGE>






              appropriately adjusted to reflect any stock dividend,
              stock split, combination or exchange of shares, merger,
              consolidation or other change in capitalization with a
              similar substantive effect upon the Plan or the Awards
              granted under the Plan.  The Committee shall have the
              power and sole discretion to determine the nature and
              amount of the adjustment to be made in each case.  In no
              event shall any adjustments be made under the provisions
              of this Section 9.05(a) to any outstanding Restricted
              Share Award if an adjustment has been or will be made to
              the shares of Common Stock awarded to a Participant in
              such person's capacity as a stockholder.

                      (b)  Sale or Reorganization.  After any
              reorganization, merger, or consolidation in which the
              Company is or is not the surviving entity, each
              Participant shall, at no additional cost, be entitled
              upon the exercise of an Option outstanding prior to such
              event to receive (subject to any required action by
              stockholders), in lieu of the number of shares of Common
              Stock receivable on exercise pursuant to such Option, the
              number and class of shares of stock or other securities
              to which such Participant would have been entitled
              pursuant to the terms of the reorganization, merger, or
              consolidation if, at the time of such reorganization,
              merger, or consolidation, such Participant had been the
              holder of record of a number of shares of Common Stock
              equal to the number of shares of Common Stock receivable
              on exercise of such Option.  Comparable rights shall
              accrue to each Participant in the event of successive
              reorganizations, mergers, or consolidations of the
              character described above.

                      (c)  Options to Purchase Stock of Acquired
              Companies.  After any reorganization, merger, or
              consolidation in which the Company shall be a surviving
              entity, the Committee may grant substituted Options under
              the provisions of the Plan, replacing old options granted
              under a plan of another party to the reorganization,
              merger, or consolidation whose stock subject to the old
              options may no longer be issued following such
              reorganization, merger, or consolidation.  The foregoing
              adjustments and manner of application of the foregoing
              provisions shall be determined by the Committee in its
              sole discretion.  Any such adjustments may provide for

                               (1)     Any and all Options shall become
                      exercisable as of the date of the Change in Control; and

                               (2)     The restrictions on vesting on all
                      Restricted Share Awards shall be deemed to have satisfied
                      as of the date of the Change in Control.

                      (e)  Existence of Awards.  The existence of outstanding
              Awards shall not affect the right of the Company or its
              stockholders to make or authorize any and all adjustments,
              recapitalizations, reclassifications, reorganizations and other
              changes in the Company's capital structure, the Company's

              Company's liquidation or dissolution, any sale or transfer of all
              or any part of the Company's assets or business, or any other

              otherwise.

              9.06  Surrender of Awards.  Any Award granted to a Participant
     under the Plan may be surrendered to the Company for cancellation on such
     terms as the Committee and holder approve.

              9.07  No Right to Award; No Right to Employment.  Except as
     provided in Article VIII, no director, employee, consultant or other
     person shall have any claim or right to be granted an Award.  Neither the
     Plan nor any action taken hereunder shall be construed as giving any
     director, employee or consultant any right to be retained by the Company
     or any of its Subsidiaries.

              9.08  Awards Not Includable for Benefit Purposes.  Income
     recognized by a Participant pursuant to the provisions of the Plan shall
     not be included in the determination of benefits under any employee
     pension benefit plan (as such term is defined in Section 3(2) of ERISA) or
     group insurance or other benefit plans applicable to the Participant that
     are maintained by the Company or any of its Subsidiaries, except as may be
     provided under the terms of such plans or determined by resolution of the
     Board.

              9.09  Governing Law.  The Plan and all determinations made and
     actions taken pursuant to the Plan shall be governed by the laws of the
     State of Delaware other than the conflict of laws provisions of such laws,
     and shall be construed in accordance therewith.

              9.10  No Strict Construction.  No rule of strict construction
     shall be implied against the Company, the Committee, or any other person
     in the interpretation of any of the terms of the Plan, any Award granted
     under the Plan or any rule or procedure established by the Committee.

              9.11  Compliance with Rule 16b-3 and Section 162(m).  It is
     intended that the Plan be applied and administered in compliance with Rule
     16b-3 and with Section 162(m).  If any provision of the Plan would be in

                                        - 18 -
<PAGE>






     violation of Rule 16b-3 or Section 162(m) if applied as written, such
     provision shall not have effect as written and shall be given effect so as
     to comply with Rule 16b-3 or Section 162(m), as the case may be, as
     determined by the Committee.  The Board is authorized to amend the Plan
     and to make any such modifications to Award Agreements to comply with Rule
     16b-3 and Section 162(m), as they may be amended from time to time, and to
     make any other such amendments or modifications deemed necessary or
     appropriate to better accomplish the purposes of the Plan in light of any
     amendments made to Rule 16b-3 and Section 162(m).  Notwithstanding the
     foregoing, the Board may amend the Plan so that it (or certain of its
     provisions) no longer comply with either or both of Rule 16b-3 or Section
     162(m) if the Board specifically determines that such compliance is no
     longer desired.

              9.12  Captions.  The captions (i.e., all Section headings) used
     in the Plan are for convenience only, do not constitute a part of the
     Plan, and shall not be deemed to limit, characterize, or affect in any way
     any provisions of the Plan, and all provisions of the Plan shall be
     construed as if no captions have been used in the Plan.

              9.13  Severability.  Whenever possible, each provision in the
     Plan and every Award at any time granted under the Plan shall be
     interpreted in such manner as to be effective and valid under applicable
     law, but if any provision of the Plan or any Award at any time granted
     under the Plan shall be held to be prohibited by or invalid under
     applicable law, then (a) such provision shall be deemed amended to
     accomplish the objectives of the provision as originally written to the
     fullest extent permitted by law, and (b) all other provisions of the Plan
     and every other Award at any time granted under the Plan shall remain in
     full force and effect.

              9.14  Legends.  All certificates for Common Stock delivered under
     the Plan shall be subject to such transfer restrictions set forth in the
     Plan and such other restrictions as the Committee may deem advisable under
     the rules, regulations, and other requirements of the SEC, any stock
     exchange upon which the Common Stock is then listed, and any applicable
     federal or state securities law.  The Committee may cause a legend or
     legends to be put on any such certificates to make appropriate references
     to such restrictions.

              9.15  Investment Representation.  The Committee may, in its
     discretion, demand that any Participant awarded an Award deliver to the
     Committee at the time of grant or exercise of such Award a written
     representation that the shares of Common Stock subject to such Award are
     to be acquired for investment and not for resale or with a view to the
     distribution thereof.  Upon such demand, delivery of such written
     representation by the Participant prior to the delivery of any shares of
     Common Stock pursuant to the grant or exercise of his or her Award shall
     be a condition precedent to the Participant's right to purchase or
     otherwise acquire such shares of Common Stock by such grant or exercise. 
     The Company is not legally obliged hereunder if fulfillment of its
     obligations under the Plan would violate federal or state securities laws.

              9.16  Amendment and Termination.

                      (a)  Amendment.  The Board shall have complete
              power and authority to amend the Plan at any time it is
              deemed necessary or appropriate; provided, however, that
              the Board shall not, without the affirmative approval of
              a simple majority of the holders of Voting Stock,
              represented, by person or by proxy, and entitled to vote
              at an annual or special meeting of the holders of Voting
              Stock, make any amendment that requires stockholder
              approval under any applicable law or rule, unless the
              Board determines that compliance with such law or rule is
              no longer desired.  No termination or amendment of the
              Plan may, without the consent of the Participant to whom
              any Award shall theretofore have been granted under the
              Plan, adversely affect the right of such individual under
              such Award; provided, however, that the Committee may, in
              its sole discretion, make provision in an Award Agreement
              for such amendments that, in its sole discretion, it
              deems appropriate.  If required by Rule 16b-3, Article
              VIII shall not be amended or modified more frequently
              than once in any period of six consecutive months other
              than to comport with changes in ERISA, the Code or the
              rules and regulations promulgated thereunder.

                      (b)  Termination.  The Board shall have the right
              and the power to terminate the Plan at any time.  No
              Award shall be granted under the Plan after the
              termination of the Plan, but the termination of the Plan
              shall not have any other effect and any Award outstanding
              at the time of the termination of the Plan may be
              exercised and may vest after termination of the Plan at
              any time prior to the expiration date of such Award to
              the same extent such Award would have been exercisable or
              vest had the Plan not terminated.

              9.17  Costs and Expenses.  All costs and expenses incurred in
     administering the Plan shall be borne by the Company.

              9.18  Unfunded Plan. The Plan shall be unfunded.  The Company
     shall not be required to establish any special or separate fund or make
     any other segregation of assets to assure the payment of any award under
     the Plan.

              9.19    Additional Restrictions on Transfer; Company's Repurchase
     Right; Legends.  

                      (a)      Additional Restrictions on Transfer. 
              Each Participant who receives an Award under the Plan
              shall be prohibited from selling, exchanging,
              transferring, pledging, hypothecating, giving or
              otherwise disposing of the underlying shares of Common

                                        - 20 -
<PAGE>






              Stock until 180 days have elapsed following such time as
              the Company has consummated an initial public offering of
              its Common Stock; provided, however, that shares of
              Common Stock may be used to pay the option price of
              Options and to pay withholding and other taxes as
              otherwise provided in the Plan.  

                      (b)      Company's Repurchase Right.  Upon a
              Participant's Termination of Employment, the Company
              shall have the right to repurchase any or all of the
              shares of Common Stock issued to the Participant with
              respect to Awards made under the Plan, whether then held
              by the Participant or a transferee.  If the Company
              wishes to exercise such right, it must pay the repurchase
              price for such shares of Common Stock to the Participant
              within sixty (60) days following the date of Termination
              of Employment.  If the Company determines to repurchase
              shares of Common Stock from the Participant, the Company
              shall pay the affected Participant the Fair Market Value
              of the shares of Common Stock to be repurchased, as
              determined by the Committee, without regard to any
              restrictions on transfer to which the underlying shares
              of Common Stock may be subject.  The Company's right to
              repurchase shares of Common Stock under this Section
              9.19(b) shall terminate with respect to all Awards
              granted under the Plan once the Company consummates an
              initial public offering of its Common Stock (even if the
              Company is within the sixty (60) day period referred to
              above with respect to a particular Participant).

                      (c)      Legends.  Until the restrictions
              provided by Sections 9.19(a) and (b) lapse by their own
              terms, each share of Common Stock issued under the Plan
              shall bear legends describing or referring to the
              existence of these restrictions.

              9.20    Loans.  The Committee shall be entitled to grant to
     Participants granted Non-Qualified Stock Options (other than Non-Employee
     Director Options) the right to pay the exercise price of such Options by
     delivery to the Company of an amount of cash equal to the par value per
     share of Common Stock purchased on exercise and a recourse promissory
     note.  Each such recourse promissory note shall have the following terms
     and conditions: (a) such promissory note shall not bear interest for the
     first year following the issuance thereof but thereafter shall bear
     interest at 2% over the prime rate of Citibank on such one year
     anniversary date, (b) interest shall be due and payable quarterly in
     arrears beginning in the second year, (c) the principal amount shall be
     due in full on the second anniversary date, (d) principal and accrued
     interest may be prepaid at any time, in whole or in part, without penalty,
     (e) in the event of a default in the payment of principal or interest when
     due and the continuance of such default for ten (10) days, the full
     principal amount of the promissory note plus accrued and unpaid interest

                                        - 21 -

     shall become immediately due and payable, and (vi) the promissory note
     shall be secured by a pledge to the Corporation of shares of Common Stock
     having a Fair Market Value equal to 110% of the principal amount of the
     promissory note.

     from such audit.  The cost of any such audit shall be borne solely by TIS,
     unless discrepancies exceed ten percent (10%) of the TIS Software payments
     paid by V-ONE during any quarter in which case the cost of such audit

                                   ---------------

              4.1     MAINTENANCE.  V-ONE has inspected the TIS Internet
     Firewall Toolkit upon which the TIS Software and the TIS Documentation are
     based and has determined the suitability, adequacy and proper operation of
     the software to its satisfaction.  TIS will provide V-ONE software
     telephone technical support during substantially all normal TIS working
     hours.  TIS shall provide V-ONE with any modifications, enhancements, or
     new versions of the TIS Software promptly when ready for delivery to end
     user customers.

              4.2     CUSTOMER SUPPORT.  TIS shall not be responsible for
     providing any support for the TIS Software to End User Customers.  V-ONE
     will provide first line support to End User Customers.

     establish a TIS Software Problem Resolution Team consisting of qualified
     UNIX programmer personnel, with a maximum of five (5).  These personnel
     will gain familiarity with the TIS Software and the installation process
     and provide the first line technical support for TIS Software for V-ONE
     and End User Customers.  V-ONE will identify the members of this TIS
     Software Problem Resolution Team to TIS.  The members of this team will be

     TIS Software Subscription.  V-ONE shall distribute reasonably promptly TIS
     Software Updates to End User Customers with an active TIS Software
     Subscription.

                                   ---------------

              As soon as practicable, TIS shall deliver to V-ONE two (2)
     electronic copies of the TIS Object Code and TIS Source Code, TIS
     Documentation and any such other information, documentation and
     instructions reasonably deemed necessary by TIS to enable V-ONE to perform
     its obligations under this Agreement (collectively the "Master Copy"). 
     TIS shall provide additional copies as necessary or appropriate upon any
     changes to TIS Object Code, TIS Source Code or TIS Documentation promptly
     when ready for delivery to end user customers.


                          6.  ADDITIONAL OBLIGATION OF V-ONE
                          ----------------------------------

              6.1     PRODUCT IDENTIFICATION.  V-ONE agrees that it shall
     clearly identify on all TIS Software packaging, supporting document, and
     advertisements that the TIS Software is "Trusted Information Systems'
     Gauntlet Internet Firewall", except as otherwise provided in this
     Agreement, and shall include such proprietary notices as may be reasonably
     requested by TIS.

              6.2     PRODUCT MARKETING.  V-ONE is authorized to represent to
     its End User Customers only such facts about the TIS Software as TIS
     states in its product descriptions, advertising and promotional materials
     or as may be stated in other non-confidential written material furnished
     by TIS.  V-ONE agrees to obtain written TIS concurrence, prior to
     publication, on the accuracy of statements describing TIS Software that
     are developed by V-ONE for product packaging, advertising and promotional
     materials.  TIS will use its best efforts to provide written approval or
     corrections within three TIS working days following the receipt of V-ONE's
     request for concurrence, and if approval or disapproval is not provided
     within five TIS working days, TIS waives its right to approve the
     particular publication.

              6.3     LICENSE AGREEMENTS.  V-ONE shall cause to be delivered to
     each End user Customer a license agreement which shall contain, at a
     minimum, all of the limitations of rights and the protection for TIS which
     are contained in Section 2.4.1., 7.1, 7.2, 7.3, 7.4, and 9.19 of this
     Agreement to the extent they apply to the rights granted to End user
     Customers.  V-ONE shall submit to TIS for its approval of such terms,
     which shall not be unreasonably withheld, a copy of its general form of
     sublicense agreement.  V-ONE shall use its reasonable efforts to ensure
     that all End user Customers abide by the terms of such license agreements
     and TIS shall retain the right to enforce such license agreements
     directly.

              6.4     CONFIDENTIALITY.

                      6.4.1  Each party understands and agrees that in the
     other party's performance of its duties and exercise of its rights

                                          6









     hereunder, such party will communicate certain confidential and
     proprietary information concerning TIS Software, Software Modifications,
     know-how, technology, techniques or marketing plans (collectively, the
     "Know-How).  Neither party shall use the Know-How of the other for any
     purpose other than the performance of this Agreement.  To the extent such
     information is confidential and proprietary to and trade secrets of the
     party disclosing such information, all such disclosures are made in utmost
     confidence.  Except as expressly authorized herein, each party agrees to
     hold all the Know-How within its own organization and shall not, without
     specific written consent of the disclosing party or as authorized herein,
     utilize in any manner, publish, communicate or disclose any part of such
     Know-How to third parties.  Each party will take all reasonable steps to
     protect the security, confidentiality and trade secrets status of the
     Know-How and will take such steps as are consistent with protection of its
     own confidential and proprietary information (but will in no event
     exercise less than reasonable care) to ensure that the provisions of this
     Agreement are not violated by such party's End User Customers, employees,
     agents or any other person to whom such has made lawful disclosure
     hereunder.  A party's obligations with respect to a particular portion of
     the Know-How will cease if and when that portion (i) becomes part of the
     public domain without any wrongful act attributable to such party; (ii) is
     lawfully received by such party from a third party without violation of
     this Agreement or any similar agreement; (iii) is approved for release by
     written authorization of the other party; (iv) is already known by such
     party as evidenced by its written records; or (v) is independently
     developed by such party, provided that the person or persons responsible
     for development did not have access to the Know-How.

                      6.4.2  V-ONE agrees to take all reasonable steps to
     protect the security and confidentiality of all data, information,
     programs, systems, materials, techniques and/or procedures relating to the
     TIS Source Code and further agrees not to remove or destroy any copyright
     or proprietary markings or confidential legends placed upon or contained
     within the TIS Source Code or Documentation, and to insert such copyright
     or proprietary markings or confidential legends in any copies of the TIS
     Source Codes or Documentation.  Except as specifically permitted in this
     Agreement, V-ONE agrees that it will not sell, license, distribute, copy
     or duplicate, or permit anyone else to sell, license, distribute, copy or
     duplicate, any aspect of the TIS Source Code.

              6.4.3  Each party acknowledges that the restrictions contained in
     this Section are reasonable and necessary to protect the other party's
     legitimate interests, that remedies at law will be inadequate, that any
     violation of these restrictions will cause irreparable damage within a
     short period of time and that the non-breaching party will be entitled to
     injunctive relief against such violation.  Each party further agrees that
     all confidentiality commitments hereunder shall survive the expiration or
     termination of this Agreement or the license granted herein.

              6.5     PROTECTION OF PROPRIETARY RIGHTS.  V-ONE shall, at its
     own costs and expense, protect and defend TIS's exclusive ownership of the
     TIS Software and all patents, copyrights, trademarks, proprietary and

                                          7









     trade secret rights associated with the foregoing against all claims,
     liens, and legal processes of creditors of V-ONE brought against V-ONE or
     TIS and keep the same free and clear from all such claims, liens and
     processes.  V-ONE shall immediately advise TIS in writing of the
     occurrence of any such claim, lien or legal process, and TIS, at its
     option and expense, shall have the right at any time, but not the
     obligation, to either monitor and participate in, or to control and direct
     (but not with respect to any aspect involving solely the liability of V-
     ONE, the investigation, preparation and settlement of any such claim, lien
     and legal process.  V-ONE shall fully cooperate with TIS in any such
     action.
              6.6     NOTICES.  Each party shall promptly advise the other of
     any legal notices served on such party which might affect the other party
     or other party's products.

              6.7     COSTS AND EXPENSES.  Except as otherwise expressly
     provided in this Agreement, each party shall be solely responsible for all
     of its costs, salaries and other expenses incurred in connection with the
     performance of its obligations hereunder, and the other party shall not
     have any liability, obligation or responsibility whatsoever therefore.

              6.8     INDEMNITY, V-ONE EXPRESSLY SAVES, INDEMNIFIES AND HOLDS
     TIS, ITS SUBSIDIARIES, AGENTS AND AFFILIATES HARMLESS FROM (i) ANY AND ALL
     LIABILITY OF ANY KIND OR NATURE WHATSOEVER TO V-ONE's CUSTOMERS,
     DISTRIBUTORS AND THIRD PARTIES WHICH MAY ARISE FROM ACTS OF V-ONE OR FROM
     THE LICENSE OF THE TIS SOFTWARE BY V-ONE, OR ANY DOCUMENTATION, SERVICES
     OR ANY OTHER ITEM FURNISHED BY V-ONE TO ITS CUSTOMERS; AND (ii) ANY
     LIABILITY ARISING IN CONNECTION WITH AN UNAUTHORIZED STATEMENT OR
     MISREPRESENTATION OF FACT MADE BY V-ONE OR ITS AGENTS, EMPLOYEES OR
     DISTRIBUTORS TO ANY PARTY WITH RESPECT TO THE TIS SOFTWARE.

                 7.  DISCLAIMER LIMITATION OF LIABILITY, WARRANTY AND
                          INTELLECTUAL PROPERTY INDEMNITIES
                 ----------------------------------------------------

              7.1     DISCLAIMER.  THE TIS SOFTWARE IS PROVIDED "AS-IS" WITHOUT
     ANY WARRANTY WHATSOEVER.  TIS DISCLAIMS ALL WARRANTIES WITH REGARD TO THE
     TIS SOFTWARE INCLUDING ANY AND ALL IMPLIED WARRANTIES OF MERCHANTABILITY
     AND FITNESS FOR A PARTICULAR PURPOSE AND ALL OBLIGATIONS OR LIABILITIES ON
     THE PART OF TIS FOR DAMAGES INCLUDING BUT NOT LIMITED TO CONSEQUENTIAL
     DAMAGES ARISING OUT OF, OR IN CONNECTION WITH, THE USE OR PERFORMANCE OF
     THE TIS SOFTWARE.

              7.2     LIMITATION OF LIABILITY.  IN NO EVENT WILL TIS BE LIABLE
     TO V-ONE OR ANY THIRD PARTIES FOR DIRECT, INDIRECT, INCIDENTAL, SPECIAL OR
     CONSEQUENTIAL DAMAGES OR LOST PROFITS EVEN IF TIS HAS BEEN ADVISED OF THE
     POSSIBILITY OF SUCH DAMAGES.

              7.3     PROPRIETARY RIGHTS INFRINGEMENT BY TIS

                      7.3.1  TIS shall indemnify and hold V-ONE harmless from
     any and all liability, damages, costs or expenses (including reasonable

                                          8









     attorneys' fees) which may be sustained or incurred by V-ONE as a result
     of any claim or claims that the unmodified TIS Software as delivered by
     TIS (excluding Software Modifications) infringes on a patent, copyright or
     trade secret.  TIS shall have no obligation to V-ONE pursuant to this
     Section 7.3 unless: (i) V-ONE gives TIS prompt written notice of the
     claim; (ii) TIS is given the right to control and direct the
     investigation, preparation, defense and settlement of the claim; and (iii)
     the claim is based on V-ONE's use of the unmodified TIS Software in
     accordance with this Agreement.

                      7.3.2  If TIS receives notice of an alleged infringement,
     TIS shall have the right, at its sole option, to obtain the right to
     continue use of the TIS Software or modify the TIS Software so that it is
     not longer infringing.  If neither of the foregoing options is reasonably
     available to TIS, then the license rights granted pursuant to Section 2 of
     this Agreement may be terminated at the option of any party hereto.

                      7.3.3  The rights and remedies set forth in Section 7.3.1
     and 7.3.2 above state the entire obligation of TIS and the exclusive
     remedies of V-ONE concerning TIS's proprietary rights infringement.

              7.4     PROPRIETARY RIGHTS INFRINGEMENT BY V-ONE

                      7.4.1  V-ONE shall indemnify and hold TIS harmless from
     any and all liability, damage, costs or expenses to third parties
     (including reasonable attorneys' fees) which may be sustained or incurred
     as a result of any claim or claims that the Software Modifications
     infringe on a patent, copyright or trade secret.  V-ONE shall have no
     obligation to TIS pursuant to this Section 7.4.1 unless: (i) TIS gives V-
     ONE prompt written notice of the claim; (ii) V-ONE is given the right to
     control and direct the investigation, preparation, defense and settlement
     of the claim; and (iii) the claim is not based solely on V-ONE's use of
     the unmodified TIS Software.

                      7.4.2  If V-ONE receives notice of an alleged
     infringement, V-ONE shall have the right, at its sole option, to obtain
     the right to continued use of the Software Modifications or to replace or
     modify the Software Modifications so that they are no longer infringing. 
     If neither of the foregoing options is reasonably available to V-ONE, then
     the license rights granted pursuant to Section 2 of this Agreement may be
     terminated at the option of any party hereto, and in the event of such
     termination, TIS shall retain all License Fees paid by V-ONE hereunder.

                      7.4.3  The rights and remedies set forth in Sections
     7.4.1 and 7.4.2 above state the entire obligation of V-ONE and the
     exclusive remedies of TIS concerning V-ONE's proprietary rights
     infringement.

                               8.  TERM AND TERMINATION
                               ------------------------

              8.1     TERM.  The license rights granted pursuant to Section 2
     hereof shall be effective as of the date hereof and shall continue in full
     force and effect until December 31, following the second anniversary of
     this Agreement unless sooner terminated pursuant to the terms of this
     Agreement.

              8.2     RENEWAL.  The license rights granted pursuant to Section
     2 of this agreement shall be automatically extended twice for successive
     one-year terms on the first day of each calendar year, provided that V-
     ONE:

                      8.2.1      Is not in material breach of this Agreement.

                      8.2.2  Is not delinquent in any payments to TIS at the
     same time of the renewal.

                      8.2.3  Provides TIS with a minimum of $20,000 in combined
     fees from Per copy License Fees and Per Copy Annual Subscription Fees in
     the preceding full calendar year.  Failure shall result in the termination
     of the license rights granted pursuant to Section 2 of this Agreement
     effective as of the last day of the calendar year for which the minimum
     combined fees from annual Per Copy License Fees and Per Copy Annual
     Subscription Fees were not paid to TIS.

              8.3     TERMINATION.  Notwithstanding the foregoing, either party
     shall be entitled to terminate the license rights granted pursuant to this
     Agreement at any time on written notice to the other in the event of a
     material breach of this Agreement by such other party and a failure to
     cure such breach within a period of thirty (30) days following receipt of
     written notice specifying that a breach has occurred, or if such breach is
     not reasonably susceptive to cure within such 30 day period and the
     breaching party does not commence remedial action within such 30 day
     period, and thereafter diligently continues such action until the breach
     is cured.  Notwithstanding the foregoing, should V-ONE on one or more
     occasion in any twelve (12) month period perform or fail to perform any
     act which gives TIS the right to terminate all or any part of the licensed
     rights granted to V-ONE, but for V-ONE's right to remedy such breach, TIS
     may on such second or subsequent breach, terminate this agreement
     forthwith by giving notice of such termination to V-ONE.

              8.4     INSOLVENCY.  In the event that V-ONE be adjudged
     insolvent or bankrupt, or upon the institution of any proceedings by or
     against it seeking relief, reorganization or arrangement under any laws
     relating to insolvency, or upon any assignment for the benefit of
     creditors, or upon the appointment of a receiver, liquidator or trustee of
     any of its property or assets, or upon the liquidation, dissolution or
     winding up of its business, then and in any such events the license rights
     granted pursuant to Section 2 of this Agreement may forthwith be
     terminated or canceled by the other part upon giving written notice

                                          10









     thereof, and upon the giving of such notice the license rights granted
     pursuant to Section 2 of this Agreement shall terminate forthwith;
     provided that, the rights of any sublicenses with respect to the TIS
     Software shall remain unaffected by such termination.

              8.5     TRANSFER AND ASSIGNMENT.  The license rights granted
     pursuant to Section 2 of this Agreement may not be transferred, by
     operation of law or otherwise, to any entity (including any successor or
     affiliate of V-ONE) except with the prior written consent of TIS that will
     not be unreasonably withheld; provided that, TIS hereby confirms and
     agrees that such consent will not be withheld for any proposed assignment
     or transfer in connection with a change of control in ownership of V-ONE
     or any sublicensee hereunder.  TIS may freely assign its rights under this
     Agreement.

              8.6     DISPOSITION OF TIS SOFTWARE AND TIS DOCUMENTATION ON
     TERMINATION.  Upon the expiration or termination of the license rights
     granted pursuant to this Agreement for any reason, the license rights
     granted pursuant to Section 2 of this Agreement shall immediately cease
     and terminate (except as provided below) and the remaining provisions
     hereof (including without limitation the confidentiality provisions of
     Section 6.4 hereof) shall remain in full force and effect.  If the license
     rights granted pursuant to Section 2 of this Agreement have expired or are
     terminated for any reason, V-ONE shall cease making copies of, using or
     licensing the TIS Software, except for such actions by V-ONE as are
     reasonably necessary to provide for sublicenses previously granted and
     orders placed with V-ONE in the ordinary course of business prior to such
     expiration or termination.  V-ONE shall return the Master Copies in V-
     ONE's possession to TIS as soon practicable after such expiration or
     termination and shall destroy or deliver to TIS all copies of the TIS
     Software.  Notwithstanding the above, for a period of two years after the
     date of expiration or termination of the license rights granted under this
     Agreement, V-ONE may retain one copy of the TIS Source Code and is hereby
     licensed for such term to use such TIS Source Code internally solely for
     the purpose of supporting End user Customers of TIS Software.  Upon the
     expiration of such two-year period, V-ONE shall destroy or return to TIS
     such single copy of TIS Source Code.


                             9.  MISCELLANEOUS PROVISIONS
                             ----------------------------

     unenforceable, the remained of this Agreement and application of such

     Agreement with valid and enforceable provisions which will achieve, to the
     extent possible, the economic, business and other purposes of the void or
     unenforceable provisions.

              9.4     ENTIRE AGREEMENT.  This Agreement and the exhibits hereto
     constitute the entire understanding and agreement of the parties hereto
     with respect to the subject matter hereof and thereof and supersede all
     prior and contemporaneous agreements or understandings, inducements or

              9.9     NO WAIVER.  The failure of any party to enforce any of
     the provisions hereof shall not be construed to be a waiver of the right
     of such party thereafter to enforce such provisions.

              9.10  OTHER REMEDIES.  Any and all remedies herein expressly
     conferred upon a party shall be deemed cumulative with and not exclusive
     of any other remedy conferred hereby or by law, and the exercise of any
     one remedy shall not preclude the exercise of any other.

              9.11  RESOLUTION OF PROBLEMS; ATTORNEY'S FEES.  In the event of
     any problem, claim, or dispute arising from this Agreement, the aggrieved
     party shall promptly notify the other party of the existence of the
     problem, claim, or dispute, and such party shall promptly undertake all
     reasonable efforts to resolve the matter within thirty days of such
     notice.  If such efforts are not successful, the parties shall meet
     promptly thereafter to resolve the matter amicably, and each party shall
     exert its reasonable best efforts toward this solution.  If the matter
     cannot be resolved through this process, then the parties shall submit the
     matter to non-binding arbitration, in accordance with the rules of the
     American Arbitration Association.  The arbitration shall be held in
     Washington, D.C., and shall utilize a single arbitrator selected by the
     parties.  Each party shall bear one-half of the costs of the arbitration. 
     In the event the arbitration process does not lead to resolution of the
     problem, then the parties shall then have recourse to all available rights
     and remedies under applicable law.  Should suit be brought to enforce or
     interpret any part of this Agreement, the prevailing party shall be
     entitled to recover, as an element of the costs of suit and not as
     damages, reasonable attorneys' fees to be fixed by the court (including
     without limitation, costs, expenses and fees on any appeal).

              9.12  NOTICES.  Whenever any party hereto desires or is required
     to give any notice, demand, or request with respect to this Agreement,
     each such communication shall be in writing and shall be effective only if
     it is delivered by personal service or mailed, United States certified

     Agreement authorized as an agent, employee or legal representative of any
     other party.  No party shall have the power to control the activities and
     operations of any other, and their status is, and at all times, will
     continue to be, that of independent contractors with respect to each
     other.  No party shall have any power or authority to bind or commit any
     other.  No party shall hold itself out as having any authority or
     relationship in contravention of this Section.

     with the other parties and to execute such further instruments, documents
     and agreements and to give such further written assurances, as may be

     without first obtaining such license or approval.

              9.19  ABSENCE OF THIRD PARTY BENEFICIARY RIGHTS.  No provisions
     of this Agreement are intended nor shall be interpreted to provide or
     create any third party beneficiary rights or any other rights of any kind

     hereto or any other person; unless specifically provided otherwise herein,
     and, except as so provided, all provisions hereof shall be personal solely

     Territory:

     WORLDWIDE; PROVIDED, HOWEVER, THAT OEM SHALL NOT GRANT  LICENSES FOR USE OF

     are included in the Licensed Software.  Licensed Software shall include
     modifications and enhancements (including all New Releases and New
     Versions) to such software as provided by RSA to OEM under this Agreement.

                      2.1.2  Use the RSA Source Code to provide support of
     Bundled Products to End User Customers.

                      2.1.3  Compile the RSA Source Code to create object code
     solely to permit creation of Interface Modifications and for the purposes
     set forth in Section 2.2 (with the limitations set forth in Section 2.3).

     of the RSA Software can be added and additional Bundled Products can be
     added by executing an amendment to a License/Product Schedule or a new
     License/Product Schedule.  RSA hereby grants OEM a non-exclusive, non-

     in Section 2.2 shall be limited as follows:

                      2.3.1  Sublicenses of the RSA Object Code to Licensed
     Software shall be granted only to (i) Distributors and (ii) End User
     Customers.

                      2.3.2  OEM may not in any way sell, rent, license,
     sublicense or otherwise distribute the RSA Software or any part thereof or
     the right to use the RSA Software or any part thereof as a stand-alone
     product to any person or entity.

                      2.3.3  OEM may not incorporate into any Bundled Product

     Page 6


     functionalities of such Licensed Software with respect to such Bundled
     Product.

              2.4     TITLE.

                      2.4.1  Except for the limited licenses granted in
     Sections 2.1 and 2.2, RSA shall at all times retain full and exclusive
     right, title and ownership interest in and to the RSA Software and in any
     and all related patents, trademarks, copyrights or proprietary or trade
     secret rights.

                      2.4.2  OEM shall at all times retain full and exclusive
     right, title and ownership interest in and to the Interface Modifications
     and in any and all related copyrights or proprietary or trade secret
     rights; provided, however, that OEM hereby agrees that it will not assert
     against RSA any of such copyrights or proprietary or trade secret rights
     with respect to any interfaces independently developed by RSA without
     reference to the source code to the Interface Modifications.

     3.       LICENSE FEES
              ------------

              3.1     LICENSE FEES.  In consideration of RSA's grant to OEM of
     the limited license rights hereunder, OEM shall pay to RSA the amounts set
     forth below (the "License Fees"):

                      3.1.1  SOURCE CODE LICENSE FEES.  If RSA is granting to
     OEM RSA Source Code license rights as specified in a License/Product
     Schedule, OEM shall pay to RSA the license fee as specified on each such
     License/Product Schedule.

                      3.1.2    OBJECT CODE LICENSE FEES.  In consideration of
     RSA's grant to OEM of the RSA Object Code sublicense rights for each
     Bundled Product described in each License/Product Schedule, OEM shall pay
     to RSA the license fees set forth in each such License/Product Schedule,
     subject to the following:

                               3.1.2.1  FIXED DOLLAR AMOUNT.  If a fixed dollar
     fee is specified for each copy/unit of a Bundled Product licensed or
     otherwise distributed by OEM or a Distributor, the License Fee per
     copy/unit shall be in the amount specified in the License Product
     Schedule.

                               3.1.2.2  PERCENTAGE OF NET SALES.  If a License
     Fee based on Net Sales is specified in the License/Product Schedule, a
     License Fee shall be due for each copy/unit of a Bundled Product licensed
     or otherwise distributed by OEM or a Distributor, in the amount of the
     specified percentage of the Net Sales Price of the Bundled Product.  The
     "Net Sales Price" shall be the gross amount of all cash, in-kind or other

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 7


     consideration receivable by OEM or such Distributor at any time in
     consideration of the licensing or other distribution of the Bundled
     Product, excluding any amounts received by OEM or such Distributor for
     sales and use taxes, shipping, insurance and duties, and reduced by all
     discounts, rebates, refunds or allowances granted in the ordinary course
     of business.  For the purposes of determining Net Sales Price, the amount
     of in-kind or other non-cash consideration receivable by OEM shall be
     deemed to have a dollar value equal to the standard price (as listed in
     OEM's published price schedule on the date of the grant of the license or
     the sale in question) ("Standard Price") for such Bundled Product, less
     all cash paid.  With respect to a Bundled Product which is licensed or
     otherwise distributed by OEM or a Distributor as part of a larger group of
     products or as an integral part of another product, a license fee shall be
     due as set forth above as though the Bundled Product had been licensed or
     distributed separately by OEM or such Distributor; provided, however, that
     if the amount invoiced for the Bundled Product when licensed or
     distributed in this manner is more than five percent (5%) below the
     Standard Price for the Bundled Product, then the Net Sale Price relating
     to such invoice shall be deemed to be no less than ninety-five percent
     (95%) of the Standard Price, notwithstanding the actual amount of the
     invoice.

                      3.1.3  PREPAYMENT OF LICENSE FEES.  OEM shall prepay
     license fees in the amount set forth in the License/Product Schedule upon
     execution of the License/Product Schedule.  In no event shall such
     prepayment be refundable.  If OEM has prepaid License Fees with respect to
     a Bundled Product, one-half (1/2) of the License Fees accrued may be
     offset against such prepaid License Fees.  OEM shall show the application
     of prepaid fees in the licensing reports provided to RSA pursuant to
     Section 3.5.

              3.2     TAXES.  All taxes, duties, fees and other governmental
     charges of any kind (including sales and use taxes, but excluding United
     States or California taxes based on the gross revenues or net income of
     RSA) which are imposed by or under the authority of any government or any
     political subdivision thereof on the License Fees or any aspect of this
     Agreement shall be borne by OEM and shall not be considered a part of, a
     deduction from or an offset against, the License Fees.

              3.3     TERMS OF PAYMENT.  License fees shall accrue with respect
     to Bundled Products licensed or otherwise distributed by OEM or
     Distributors upon the date of invoice of the Bundled Product to an End
     User Customer or Distributor.  License fees due RSA hereunder shall be
     paid by OEM to the attention of the Software Licensing Department at RSA's
     address set forth above on or before the thirtieth (30th) day after the
     close of the calendar quarter during which the fees accrued.  If OEM has
     prepaid License Fees with respect to a Bundled Product, one-half (1/2) of
     License Fees accrued with respect to that Bundled Product may be offset
     against such prepaid License Fees.  A late payment penalty of one percent

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 8


     (1%) of any license fees not paid when due shall be assessed for each
     thirty (30) day period, or portion thereof, during which such payment is
     delayed, beginning on the thirty-first (31st) day after the last day of
     the calendar quarter to which the delayed payment relates.

              3.4     U.S. Currency.  All payments hereunder shall be paid in
     lawful United States currency.  If OEM receives payment in foreign
     currencies, the amount of its license fees to RSA shall be calculated
     using the closing exchange rate published in THE WALL STREET JOURNAL
     Western Edition on the last business day such journal is published in the
     calendar quarter immediately preceding the date of payment.

              3.5     LICENSING REPORT.  A report in reasonably detailed form
     setting forth the calculation of license fees due from OEM and signed by a
     responsible officer of OEM shall be delivered to RSA on or before the
     thirtieth (30th) day after the close of each calendar quarter during the
     term of this Agreement, regardless of whether royalty payments are
     required to be made pursuant to Section 3.3.  The report shall include, at
     a minimum, the following information (if applicable to OEM's designated
     method of calculating license fees) with respect to the relevant quarter:
     (i) the total number of copies/units of Bundled Products licensed or
     otherwise distributed (indicating the names and versions thereof); (ii) if
     applicable, the total Net Set Sales Price invoiced to Distributors and End
     User Customers; and (iii) total license fees accrued.

              3.6     AUDIT RIGHTS.  RSA shall have the right, at its sole cost
     and expense, to conduct during normal business hours and not more
     frequently than annually, an audit of the appropriate records of OEM to
     verify the number of copies/units of Bundled Products licensed or
     otherwise distributed by OEM and Distributors and, if relevant to OEM's
     designated method of calculating license fees, the Net Sales Price
     therefor.  If such amounts are found to be different than those reported,
     or the license fees accrued are different than those reported, OEM will be
     invoiced or credited for the difference, as applicable.  Any additional
     license fees, along with the late payment penalty assessed in accordance
     with Section 3.3, shall be payable within thirty (30) days of such
     invoice.  If OEM has prepaid License Fees with respect to a Bundled
     Product, one-half (1/2) of License Fees accrued with respect to that
     Bundled Product may be offset against such prepaid License Fees.  If the
     deficiency in license fees paid by OEM is greater than five percent (5%)
     of the license fees reported by OEM for any quarter, OEM will pay the
     reasonable expenses associated with such audit, in addition to the
     deficiency.

     4.       WARRANTY AND MAINTENANCE
              ------------------------

              4.1     LIMITED WARRANTY.  During the initial ninety (90)-day
     term of each License/Product Schedule RSA warrants that the Licensed

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 9


     Functionality of the Licensed Software specified in each License/Product
     Schedule will operate in material conformance to RSA's published
     specifications for such Licensed Functionality of the Licensed Software. 
     RSA does not warrant that the RSA Software or any portion thereof is
     error-free.  OEM's exclusive remedy, and RSA's entire liability in tort,
     contract or otherwise, shall be correction of any warranted nonconformity
     as provided in Section 4.4.  This limited warranty and any obligations of
     RSA under Section 4.2 shall not apply to any Interface Modifications or
     any nonconformities caused thereby and shall terminate immediately if OEM
     makes any modification to the RSA Software other than Interface
     Modifications.

              4.2     OPTIONAL MAINTENANCE.  For the year commencing upon the
     expiration of the first ninety (90) days of each License/Product Schedule
     and for each year thereafter commencing on the anniversary of such
     expiration, OEM may elect to purchase annual maintenance, as defined in
     Section 4.4, by paying the then-current annual maintenance fee.  Such
     amount shall be payable for the first year upon the execution of each
     License/Product Schedule and for each subsequent year in advance of the
     commencement of such year.  RSA may cease to offer maintenance by notice
     delivered to OEM ninety (90) days or more before the end of the then-
     current maintenance term.

              4.3     ADDITIONAL CHARGES.  In the event RSA is required to take
     actions to correct a difficulty or defect which is traced to OEM errors,
     modifications, enhancements, software or hardware, then OEM shall pay to
     RSA its time and materials charges at RSA's rates then in effect.  In the
     event RSA's personnel must travel to perform maintenance or on-site
     support, OEM shall reimburse RSA for any reasonable out-of-pocket expenses
     incurred, including travel to and from OEM's sites, lodging, meals and
     shipping, as may be necessary in connection with duties performed under
     this Section 4 by RSA.

              4.4     MAINTENANCE PROVIDED BY RSA.  During the ninety (90) days
     following commencement of a License/Product Schedule and for periods for
     which OEM has paid an annual maintenance fee, RSA will provide OEM with
     the following services:

                      4.4.1  RSA will provide telephone support to OEM during
     RSA's normal business hours.  RSA may provide on-site support reasonably
     determined to be necessary by RSA at OEM's location specified on page 1
     hereof.  RSA shall provide the support specified in this Section 4.4.1 to
     OEM's employees responsible for developing Bundled Products, maintaining
     Bundled Products, and providing support to End User Customers.  No more
     than two (2) OEM employees may obtain such support from RSA at any one
     time.  On RSA's request, OEM will provide a list with the names of the
     employees designated to receive support from RSA.  OEM may change the
     names on the list at any time by providing written notice to RSA.

                      4.4.2  In the event OEM discovers an error in the
     Licensed Functionality of the Licensed Software which causes the Licensed
     Functionality of the Licensed Software not to operate in material
     conformance to RSA's published specifications therefor, OEM shall submit
     to RSA a written report describing such error in sufficient detail to
     permit RSA to reproduce such error.  Upon receipt of any such written
     report, RSA will use its reasonable business judgment to classify a
     reported error as either:  (i) a "Level 1 Severity" error, meaning an
     error that causes the Licensed Functionality of the Licensed Software to
     fail to operate in a material manner or to produce materially incorrect
     results and for which there is no workaround or only a difficult
     workaround; or (ii) a "Level 2 Severity" error, meaning an error that
     produces a situation in which the Licensed Functionality of the Licensed
     Software is usable but does not function in the most convenient or
     expeditious manner, and the use or value of the Licensed Functionality of
     the Licensed Software suffers no material impact.  RSA will acknowledge
     receipt of a conforming error report within two (2) business days and (A)
     will use its continuing best efforts to provide a correction for any Level
     1 Severity error to OEM as early as practicable; and (B) will use its
     reasonable efforts to include a correction for any Level 2 Severity error
     in the next release of the RSA Software.

                      4.4.3  RSA will provide OEM information relating to New
     Releases and New Versions of the RSA Software during the term of this
     Agreement.  New Releases will be provided at no additional charge.  New
     Versions will be provided at RSA's standard upgrade charges in effect at
     the time.  Any New Releases or New Versions acquired by OEM shall be
     governed by all of the terms and provisions of this Agreement.

              4.5  LICENSE OF NEW RELEASES.  In the event OEM has not purchased
     optional maintenance with respect to any Licensed Software, OEM may obtain
     a license of a New Release of such Licensed Software or any service which
     is provided as a part of maintenance by paying the maintenance fees which
     would otherwise have been due from the expiration of maintenance provided
     pursuant to Section 4.1 to the date of license of such New Release.

     5.       MASTER COPY
              -----------

              As soon as practicable but not later than five (5) business days
     after the date of execution of a License/Product Schedule RSA shall
     deliver to OEM one (1) copy of each of the RSA Object Code, the RSA Source
     Code and the User Manual licensed hereunder and such other information,
     documentation and instructions reasonably deemed necessary by RSA to
     enable OEM to perform its obligations under this Agreement.

     6.       ADDITIONAL OBLIGATIONS OF OEM
              -----------------------------

              6.1     BUNDLED PRODUCT MARKETING.  OEM is authorized to
     represent to Distributors and End User Customers only such facts about the
     RSA Software as RSA states in its published product descriptions,
     advertising and promotional materials or as may be stated in other non-
     confidential written material furnished by RSA.

              6.2     CUSTOMER SUPPORT.  OEM shall, at its expense, provide all
     support for the Bundled Products to Distributors and End User Customers.

              6.3     LICENSE AGREEMENTS.  OEM shall cause to be delivered to
     each Distributor and End User Customer a license agreement which shall
     contain, at a minimum, substantially all of the limitations of rights and
     the protections for RSA which are contained in Sections 2.3, 6.4.2, 6.6,
     7.1, 7.2, 9.8 and 9.9 of this Agreement and shall prohibit Distributors
     and End User Customers pursuant to written agreements from modifying,
     reverse engineering, decompiling or disassembling the RSA Object Code or
     any part thereof.  OEM shall use its reasonable best efforts to ensure
     that all Distributors and End User Customers abide by the terms of such
     agreements.

              6.4     CONFIDENTIALITY.
                      ----------------

                      6.4.1  OEM acknowledges that in RSA's performance of its
     duties hereunder RSA will communicate to OEM (or its designees) certain
     confidential and proprietary information concerning the RSA Software, and
     know-how, technology, techniques or marketing plans related thereto
     (collectively, the "Know-How") all of which are confidential and
     proprietary to, and trade secrets of, RSA.  OEM agrees to hold all the RSA
     Software and Know-How within its own organization and shall not, without
     specific written consent of RSA or as expressly authorized herein, utilize
     in any manner, publish, communicate or disclose any part of the RSA
     Software or Know-How to third parties.  This Section 6.4.1 shall impose no
     obligation on OEM with respect to any Know-How which:  (i) at the time of
     disclosure in writing is not marked or stamped with a legend identifying
     it as "Company Private," "Proprietary," "Confidential" or a similar
     legend, or, within thirty (30) days after oral disclosure, is not so
     identified in writing; (ii) is in the public domain at the time disclosed
     by RSA; (iii) enters the public domain after disclosure other than by
     breach of OEM's obligations hereunder or by breach of another party's
     confidentiality obligations; or (iv) is shown by documentary evidence to
     have been known by OEM prior to its receipt from RSA.  OEM will take such
     steps as are consistent with OEM's protection of its own confidential and
     proprietary information (but will in no event exercise less than
     reasonable care) to ensure that the provisions of this Section 6.4.1 are

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 12


     not violated by OEM's End User Customers, Distributors, employees, agents
     or any other person.

                      6.4.2  OEM agrees not to remove or destroy any proprie-
     tary, trademark or copyright markings or confidentiality legends placed
     upon or contained within the RSA Source Code, RSA Object Code, User
     Manuals or any related materials or documentation.  OEM further agrees to
     insert and maintain:  (i) within every Bundled Product and any related
     materials or documentation a copyright notice in the name of OEM; and (ii)
     within the splash screens, user documentation, printed product collateral,
     product packaging and advertisements for the Bundled Product, the
     appropriate RSA "Licensee Seal" from the form attached as Exhibit "B" to
     this Agreement and a statement that the Bundled Product contains the RSA
     Software.  OEM shall not take any action which might adversely affect the
     validity of RSA's proprietary, trademark or copyright markings or
     ownership by RSA thereof, and shall cease to use the markings, or any
     similar markings, in any manner on the expiration or other termination of
     the license rights granted pursuant to Section 2.

                      6.4.3  OEM acknowledges the extreme importance of the
     confidentiality and trade secret status of the RSA Source Code and OEM
     agrees, in addition to complying with the requirements of Sections 6.4.1
     and 6.4.2 as they relate to the RSA Source Code, to:  (i) inform any
     employee that is granted access to all or any portion of the RSA Source
     Code of the importance of preserving the confidentiality and trade secret
     status of the RSA Source Code; and (ii) maintain a controlled, secure
     environment for the storage and use of the RSA Source Code.

                      6.4.4  The placement of a copyright notice on any of the
     RSA Software shall not constitute publication or otherwise impair the
     confidential or trade secret nature of the RSA Software.

                      6.4.5  OEM acknowledges that the restrictions contained
     in this Section 6.4 are reasonable and necessary to protect RSA's
     legitimate interests and that any violation of these restrictions will
     cause irreparable damage to RSA within a short period of time and OEM
     agrees that RSA will be entitled to injunctive relief against each
     violation.  OEM further agrees that all confidentiality commitments
     hereunder shall survive the expiration or termination for any reason of
     this Agreement or the license rights granted pursuant to Section 2.

              6.5     FEDERAL GOVERNMENT SUBLICENSE.  Any sublicense of a
     Bundled Product acquired from OEM or any Distributor under a United States
     government contract shall be subject to restrictions as set forth in
     subparagraph (c)(1)(ii) of Defense Federal Acquisition Regulations
     Supplement (DFARs) Section 252.227-7013 for Department of Defense
     contracts and as set forth in Federal Acquisition Regulations (FARs)
     Section 52.227-19 for civilian agency contracts or any successor
     regulations.  OEM agrees that any such sublicense shall set forth all of

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 13


     such restrictions and the tape or diskette label for the Bundled Product
     and any documentation delivered with the Bundled Product shall contain a
     restricted rights legend conforming to the requirements of the current,
     applicable DFARs or FARs.

              6.6     NOTICES.  OEM shall immediately advise RSA of any legal
     notices served on OEM which might affect RSA, the RSA Software or any
     Bundled Products.

              6.7     INDEMNITY.  OEM EXPRESSLY INDEMNIFIES AND HOLDS HARMLESS
     RSA, ITS SUBSIDIARIES, AGENTS AND AFFILIATES FROM:  (i) ANY AND ALL
     LIABILITY OF ANY KIND OR NATURE WHATSOEVER TO OEM'S END USER CUSTOMERS,
     DISTRIBUTORS AND THIRD PARTIES WHICH MAY ARISE FROM ACTS OF OEM OR FROM
     THE LICENSE OF BUNDLED PRODUCTS BY OEM OR ANY DOCUMENTATION, SERVICES OR
     ANY OTHER ITEM FURNISHED BY OEM TO ITS END USER CUSTOMERS OR DISTRIBUTORS;
     AND (ii) ANY LIABILITY ARISING IN CONNECTION WITH AN UNAUTHORIZED
     REPRESENTATION OR ANY MISREPRESENTATION OF FACT MADE BY OEM OR ITS AGENTS,
     EMPLOYEES OR DISTRIBUTORS TO ANY PARTY WITH RESPECT TO THE RSA SOFTWARE OR
     ANY BUNDLED PRODUCTS.

     7.       DISCLAIMER OF WARRANTIES; LIMITATION OF LIABILITY; INTELLECTUAL
              PROPERTY INDEMNITIES
              ---------------------------------------------------------------

              7.1     DISCLAIMER.  EXCEPT FOR THE EXPRESS LIMITED WARRANTY
     PROVIDED IN SECTION 4.1, THE RSA SOFTWARE IS PROVIDED "AS IS" WITHOUT ANY
     WARRANTY WHATSOEVER.  RSA DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR
     STATUTORY, AS TO ANY MATTER WHATSOEVER, INCLUDING ALL IMPLIED WARRANTIES
     OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  RSA DISCLAIMS
     ANY WARRANTY OR REPRESENTATION TO ANY PERSON OTHER THAN OEM WITH RESPECT
     TO THE RSA SOFTWARE.  OEM SHALL NOT, AND SHALL TAKE ALL MEASURES NECESSARY
     TO INSURE THAT ITS AGENTS AND EMPLOYEES DO NOT, MAKE OR PASS THROUGH ANY
     SUCH WARRANTY ON BEHALF OF RSA TO ANY DISTRIBUTOR, END USER CUSTOMER OR
     OTHER THIRD PARTY.

              7.2     LIMITATION OF LIABILITY.  IN NO EVENT WILL RSA BE LIABLE
     TO OEM (OR TO ANY PERSON CLAIMING RIGHTS DERIVED FROM OEM) FOR INDIRECT,
     INCIDENTAL, SPECIAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES ARISING OUT OF OR
     RELATED TO THE TRANSACTIONS CONTEMPLATED UNDER THIS AGREEMENT, INCLUDING
     BUT NOT LIMITED TO LOST PROFITS, BUSINESS INTERRUPTION OR LOSS OF BUSINESS
     INFORMATION, EVEN IF RSA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
     DAMAGES.  UNDER NO CIRCUMSTANCES SHALL RSA'S TOTAL LIABILITY ARISING OUT
     OF OR RELATED TO THIS AGREEMENT EXCEED THE TOTAL AMOUNT PAID BY OEM TO RSA
     HEREUNDER, REGARDLESS OF WHETHER ANY ACTION OR CLAIM IS BASED ON WARRANTY,
     CONTRACT, TORT OR OTHERWISE.

              7.3     PROPRIETARY RIGHTS INFRINGEMENT BY RSA.
                      --------------------------------------

                      7.3.1  Subject to the limitations set forth below, RSA,
     at its own expense, shall:  (i) defend, or at its option settle, any
     claim, suit or proceeding against OEM on the basis of infringement of any
     United States patent, copyright or trade secret in the field of
     cryptography by the unmodified Licensed Software as delivered by RSA
     (excluding the Interface Modifications) or any claim that RSA has no right
     to license the Licensed Software hereunder; and (ii) pay any final
     judgment entered or settlement against OEM on such issue in any such suit
     or proceeding defended by RSA.  RSA shall have no obligation to OEM
     pursuant to this Section 7.3.1 unless:  (A) OEM gives RSA prompt written
     notice of the claim; (B) RSA is given the right to control and direct the
     investigation, preparation, defense and settlement of the claim; and (C)
     the claim is based on OEM's use of the unmodified License Software in
     accordance with this Agreement.

                      7.3.2  If RSA receives notice of an alleged infringement,
     RSA shall have the right, at its sole option, to obtain the right to
     continue use of the Licensed Software or to replace or modify the Licensed
     Software so that it is no longer infringing.  If neither of the foregoing
     options is reasonably available to RSA, then the license rights granted
     pursuant to Section 2 may be terminated at the option of either party
     hereto without further obligation or liability except as provided in
     Sections 7.3.1 and 8.3 and in the event of such termination, RSA shall
     refund the License Fees paid by OEM hereunder less depreciation for use
     assuming straight line depreciation over a five (5)-year useful life.

                      7.3.3  THE RIGHTS AND REMEDIES SET FORTH IN SECTIONS
     7.3.1 AND 7.3.2 CONSTITUTE THE ENTIRE OBLIGATION OF RSA AND THE EXCLUSIVE
     REMEDIES OF OEM CONCERNING RSA'S PROPRIETARY RIGHTS INFRINGEMENT.

              7.4     PROPRIETARY RIGHTS INFRINGEMENT BY OEM.
                      --------------------------------------

                      7.4.1  Subject to the limitations set forth below, OEM,
     at its own expense, shall:  (i) defend, or at its option settle, any
     claim, suit or proceeding against RSA on the basis of infringement of any
     United States patent, copyright or trade secret by any Bundled Product
     (excluding the unmodified RSA Software) or the Interface Modifications;
     and (ii) pay any final judgment entered or settlement against RSA on such
     issue in any such suit or proceeding defended by OEM.  OEM shall have no
     obligation to RSA pursuant to this Section 7.4.1 unless:  (A) RSA gives
     OEM prompt written notice of the claim; and (B) OEM is given the right to
     control and direct the investigation, preparation, defense and settlement
     of the claim.

                      7.4.2  If OEM receives notice of an alleged infringement,
     OEM shall have the right, at its sole option, to obtain the right to
     continued use of the Interface Modifications or the Bundled Product or to
     replace or modify the Interface Modifications or Bundled Product so that
     they are no longer infringing.  If neither of the foregoing options is
     reasonably available to OEM, then the license rights granted pursuant to
     Section 2 of this Agreement may be terminated at the option of either
     party hereto without further obligation or liability except as provided in
     Sections 7.4.1 and 8.3, and in the event of such termination, RSA shall
     retain all License Fees paid by OEM hereunder.

     7.4.1 AND 7.4.2 CONSTITUTE THE ENTIRE OBLIGATION OF OEM AND THE EXCLUSIVE
     REMEDIES OF RSA CONCERNING OEM'S PROPRIETARY RIGHTS INFRINGEMENT.

     8.       TERM AND TERMINATION
              --------------------

              8.1     TERM.  The license rights granted pursuant to Section 2
     shall be effective with respect to each License/Product Schedule as of the
     date thereof and shall continue in full force and effect for each item of
     Licensed Software for an initial period as set forth on each
     License/Product Schedule unless sooner terminated pursuant to the terms of
     this Agreement.  Such license rights shall be automatically renewed for
     successive one (1)-year terms unless either party notifies the other party
     in writing of its intention not to renew at least sixty (60) days prior to
     the expiration of the then-current term.  Such non-renewal option may be
     exercised by either party with or without cause.  Notwithstanding the
     foregoing, either party shall be entitled to terminate all the license
     rights granted pursuant to this Agreement at any time on written notice to
     the other in the event of a default by the other party and a failure to
     cure such default within a period of thirty (30) days (five (5) if the
     default involves the payment of money) following receipt of written notice
     specifying that a default has occurred.

              8.2     INSOLVENCY.  In the event that either party is adjudged
     insolvent or bankrupt, or upon the institution of any proceedings by or
     against either party seeking relief, reorganization or arrangement under
     any laws relating to insolvency, or upon any assignment for the benefit of
     creditors, or upon the appointment of a receiver, liquidator or trustee of
     any of either party's property or assets, or upon the liquidation,
     dissolution or winding up of either party's business, then and in any such
     events all the license rights granted pursuant to this Agreement may
     immediately be terminated by the other party upon giving written notice.

              8.3     DISPOSITION OF RSA SOFTWARE AND USER MANUALS ON
     TERMINATION.  Upon the expiration or termination pursuant to this Section
     8 of the license rights granted pursuant to Section 2, the remaining
     provisions of this Agreement (including without limitation the

<PAGE>







     RSA Data Security, Inc.
     OEM Master License Agreement
     Page 16


     confidentiality provisions of Section 6.4) shall remain in full force and
     effect, and OEM shall cease making copies of, using or licensing the RSA
     Software and Bundled Products excepting only such copies of Bundled
     Products necessary to fill orders placed with OEM prior to such expiration
     or termination.  OEM shall destroy all copies of the RSA Software and
     Bundled Products not subject to any then-effective license agreement with
     an End User Customer and all information and documentation provided by RSA
     to OEM (including all Know-How), other than such copies of the RSA Object
     Code, the User Manual and the Bundled Products as are necessary to enable
     OEM to perform its continuing support obligations in accordance with
     Section 6.2, if any, and except as provided in the next following
     sentence.  If OEM has licensed Source Code hereunder, for a period of one
     (1) year after the date of expiration or termination of the license rights
     granted under this Agreement, OEM may retain one (1) copy of the RSA
     Source Code and is hereby licensed for such term to use such RSA Source
     Code solely for the purpose of supporting End User Customers of Bundled
     Products.  Upon the expiration of such one (1)-year period, OEM shall
     destroy or return to RSA such single copy of the RSA Source Code.

     9.       MISCELLANEOUS PROVISIONS.

              9.1     GOVERNING LAWS.  IT IS THE INTENTION OF THE PARTIES
     HERETO THAT THE INTERNAL LAWS OF THE STATE OF CALIFORNIA, U.S.A.
     (IRRESPECTIVE OF ITS CHOICE OF LAW PRINCIPLES) SHALL GOVERN THE VALIDITY
     OF THIS AGREEMENT, THE CONSTRUCTION OF ITS TERMS, AND THE INTERPRETATION
     AND ENFORCEMENT OF THE RIGHTS AND DUTIES OF THE PARTIES HERETO.  THE
     PARTIES AGREE THAT THE UNITED NATIONS CONVENTION ON CONTRACTS FOR THE
     INTERNATIONAL SALE OF GOODS SHALL NOT APPLY TO THIS AGREEMENT.  THE
     PARTIES HEREBY AGREE THAT ANY SUIT TO ENFORCE ANY PROVISION OF THIS
     AGREEMENT OR ARISING OUT OF OR BASED UPON THIS AGREEMENT OR THE BUSINESS
     RELATIONSHIP BETWEEN THE PARTIES HERETO SHALL BE BROUGHT IN THE UNITED
     STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF CALIFORNIA OR THE
     SUPERIOR OR MUNICIPAL COURT IN AND FOR THE COUNTY OF SAN MATEO,
     CALIFORNIA, U.S.A.  Each party hereby agrees that such courts shall have
     exclusive in personam jurisdiction and venue with respect to such party,
     and each party hereby submits to the exclusive in personam jurisdiction
     and venue of such courts.

              9.2  BINDING UPON SUCCESSORS AND ASSIGNS.  Except as otherwise
     provided herein, this Agreement shall be binding upon, and inure to the
     benefit of, the successors, executors, heirs, representatives,
     administrators and assigns of the parties hereto; provided, however, that
     this Agreement shall not be assignable by OEM, by operation of law or
     otherwise, without the prior written consent of RSA, which shall not be
     unreasonably withheld.  Any such purported assignment or delegation
     without RSA's written consent shall be void and of no effect.

              9.3     SEVERABILITY.  If any provision of this Agreement, or the
     application thereof, shall for any reason and to any extent, be invalid or

     unenforceable, the remainder of this Agreement and application of such
     provision to other persons or circumstances shall be interpreted so as
     best to reasonably effect the intent of the parties hereto.  IT IS
     EXPRESSLY UNDERSTOOD AND AGREED THAT EACH AND EVERY PROVISION OF THIS
     AGREEMENT WHICH PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF
     WARRANTIES OR EXCLUSION OF DAMAGES IS INTENDED BY THE PARTIES TO BE
     SEVERABLE AND INDEPENDENT OF ANY OTHER PROVISION AND TO BE ENFORCED AS

     LICENSE AND MAINTENANCE FEES:
     ----------------------------

     Prepayment of License Fees:
     --------------------------

     Waived for this License/Product Schedule


     Source Code and Object Code License Fees:
     ----------------------------------------

          1.  AMOUNT OF LICENSE FEES.  The provisions of Sections 3.1.1 and
     3.1.2 of the Agreement shall not apply to this License/Product Schedule. 
     As consideration for the RSA Source Code and RSA Object Code licenses
     granted in this License/Product Schedule, OEM shall pay to RSA an amount
     equal to two percent (2%) of OEM's Gross Revenues during the term of this
     License/Product Schedule.  "Gross Revenues" means OEM's gross revenues
     from all of its products and services, as reflected in OEM's financial
     statements prepared in accordance with generally accepted accounting
     principles.  RSA shall have the option, at any time following the date of
     the Amendment until the date of the initial public offering of OEM's
     securities, to convert its right to future License Fees described in this
     paragraph 1 to Common Stock of OEM representing two percent (2%) of OEM's
     then-outstanding voting securities on an as-converted basis.

          2.  PAYMENT AND REPORTING.  Sections 3.3, 3.5 and 3.6 of the
     Agreement shall not apply to this License/Product Schedule.  License Fees
     with respect to this License/Product Schedule shall accrue when OEM's
     Gross Revenues are realized, as determined for OEM's accounting purposes,
     in accordance with generally accepted accounting principles.  License Fees
     due RSA shall be paid by OEM to the attention of the Software Licensing
     Department at RSA's address set forth on the first page of the Agreement
     on or before the thirtieth (30th) day after the close of the calendar
     quarter during which the License Fees accrued.  A late payment penalty of
     one percent (1%) of any License Fees not paid when due shall be assessed
     for each thirty (30)-day period, or portion thereof, during which such
     payment is delayed beginning on the thirty-first (31st) day after the last
     day of the calendar quarter to which the delayed payment relates.  OEM's
     unaudited quarterly financial statementsin reasonably detailed form
     setting forth OEM's Gross Revenues and the calculation of License Fees due
     from OEM, certified by a responsible officer of OEM, shall be delivered to
     RSA on or before the thirtieth (30th) day after the close of each calendar
     quarter during the term of this License/Product Schedule, regardless of
     whether License Fees are due for such quarter pursuant to the preceding
     sentences.  Within sixty (60) days after the close of OEM's fiscal year,
     OEM shall provide RSA with a copy of OEM's audited financial statements
     showing OEM's Gross Revenues for such fiscal year, along with a

<PAGE>







     Exhibit "A"
     License/Product Schedule
     Page 5



     reconciliation of those Gross Revenues with the Gross Revenues previously
     reported on a quarterly basis with respect to such fiscal year.  OEM
     shall, at the same time, pay to RSA any deficiency in License Fees
     previously paid for such fiscal year.  If OEM has overpaid License Fees
     for such fiscal year, such overpayment shall be credited against OEM's
     next required payment of License Fees.

          3.  MINIMUM LICENSE FEES FOR VIRTUAL SmartCAT.  In addition to the
     License Fees payable by OEM pursuant to paragraph 2 above, OEM shall pay
     to RSA the amount of One Dollar ($1.00) for each copy of Virtual SmartCAT
     sublicensed or otherwise distributed by OEM, unless: (i) OEM charges more
     than a de minimis amount of royalties or other fees such copy, or (ii)
     such copy contains a feature which disables the functionality of Virtual
     SmartCAT within forty-five (45) days or less of the date the copy is
     delivered.

          4.  ADDITIONAL CONSIDERATION.  As additional consideration for the
     RSA Source Code and RSA Object Code licenses granted in this
     License/Product Schedule, OEM will:

          a.  Promptly after the date of execution of this License/Product
     Schedule provide to RSA at no cost to RSA one complete SmartWall system
     and grant RSA a non-exclusive, perpetual, irrevocable, royalty-free
     license to use such SmartWall system for RSA's internal business purposes. 
     Such license shall include all bug fixes, updates, enhancements, support,
     and new releases provided to OEM's other licensees, at no additional cost
     to RSA.

          b.  Each copy of SmartCAT Cyber Wallet distributed by or under
     authority of OEM will identify RSA as the provider of the encryption
     technology within the product by displaying, with each occurrence of the
     product name "Cyber Wallet," the words "with RSA encryption" or the
     appropriate RSA licensee seal from Exhibit B to the Agreement.

     Maintenance Fees for this License/Product Schedule:
     --------------------------------------------------

     Annual maintenance fees for the Bundled Products covered by this
     License/Product Schedule shall be waived during the periods that License
     Fees are paid to RSA pursuant to this License/Product Schedule. 
     Notwithstanding the provisions of Section 4.4.3 of the Agreement, New
     Versions of the Licensed Software will be provided to OEM at no additional
     charge during the period that License Fees are paid to RSA pursuant to
     this License/Product Schedule; provided, however, that OEM shall not on
     the basis of so obtaining any New Version receive any rights under this
     License/Product Schedule to any algorithms not included with the Licensed
     Software as designated on page 2 of this License/Product Schedule.

              THIS AMENDMENT NUMBER TWO TO BSAFE/TIPEM OEM MASTER LICENSE
     AGREEMENT (the "Amendment") modifies that certain BSAFE/TIPEM OEM Master
     License Agreement dated as of December 30, 1994 by and between RSA Data

     and not otherwise defined shall have the meanings set forth in the
     Agreement.

              2.      EXERCISE OF OPTION. Pursuant to the First Amendment, OEM
     granted RSA an option to convert its right to [certain] future License
     Fees to Common Stock of OEM, as more particularly set forth in the First
     Amendment.  RSA hereby exercises such option to convert, and the parties
     hereby agree, in connection therewith, to enter into the Conversion

                      amended to read in its entirety as follows:

                               3.2     LIMITATION OF LIABILITY.  IN NO EVENT
                      WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR TO ANY
                      PERSON CLAIMING RIGHTS DERIVED FROM THE OTHER PARTY) FOR
                      INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR EXEMPLARY
                      DAMAGES ARISING OUT OF OR RELATED TO THE TRANSACTIONS
                      CONTEMPLATED UNDER THIS AGREEMENT, INCLUDING BUT NOT
                      LIMITED TO LOST PROFITS, BUSINESS INTERRUPTION OR LOSS OF

                      OF THE POSSIBILITY OF SUCH DAMAGES.  IN NO EVENT WILL
                      EITHER PARTY'S LIABILITY ARISING OUT OF OR RELATED TO
                      THIS AGREEMENT EXCEED THE AMOUNT OF $250,000, REGARDLESS
                      OF WHETHER ANY ACTION OR CLAIM IS BASED ON WARRANTY,

                      LIMITATIONS OF LIABILITY SHALL APPLY TO EITHER PARTY'S
                      INDEMNITY OBLIGATIONS HEREUNDER OR TO ANY BREACHES OF
                      SECTIONS 2 AND 6.4 AS SUCH BREACHES RELATE TO RSA'S
                      SOURCE CODE, OR TO ANY OTHER BREACHES OF SECTIONS 2, 6.1,
                      6.3, 6.4 AND 6.5 ARISING OUT OF A PARTY'S INTENTIONAL
                      CONDUCT OR FAILURE TO EXERCISE REASONABLE CARE.

              3.3     Section 7.3.1.  Section 7.3.1 of the Agreement is amended

     the Agreement (attached to the First Amendment) is replaced in its
     entirety with the "Exhibit "A" (License/Product Schedule No. 0596-VON-O-

     SPECIAL TERMS AND CONDITIONS
     ----------------------------

     1.      Limited Rights to Sublicense.
             -----------------------------
     Notwithstanding the provisions of Section 2.3.1 of the Agreement, RSA
     further hereby grants to OEM a non-exclusive, non-transferable, non-
     assignable license during the term of this License/Product Schedule to
     sublicense its rights granted in Section 2.2, as limited by Section 2.3,
     of the Agreement with respect to the RSA Object Code as part of the
     Bundled Products to OEM's licensees in the Territory (each, an "OEM
     Sublicensee") for use only (i) in their own products in which substantial
     functionality or value is added to the Bundled Products so that such
     products are not a substitute for the RSA Software, or (ii) in their own
     privately-labelled products consisting of the Bundled Products with no
     modifications other than minor packaging changes (collectively,
     "Sublicensee Products").  All sublicenses permitted under this paragraph
     shall be subject to all of the following conditions: (i) all such
     sublicenses will be granted in a signed writing containing at a minimum
     all of the restrictions set forth in Exhibit "A-1" attached hereto, and
     RSA shall be an express third party beneficiary of such sublicense
     agreements; (ii) OEM shall use its best efforts to enforce the provisions
     of such sublicenses as they relate to RSA and the RSA Software; (iii) the
     Sublicensee Products shall incorporate the Licensed Functionality of the
     RSA Object Code in such a way so as to ensure that the security functions
     of the RSA Object Code may only be accessed by the functionality of the
     Sublicensee Product in which it is included so that the RSA Object Code
     shall not be directly accessible to End User Customers or to software
     products other than the Sublicensee Products; (iv) the OEM Sublicensees to
     whom such rights are sublicensed shall have no further right to sublicense
     such rights; (v) on or before the date that OEM grants any sublicense
     hereunder, OEM shall submit to RSA an Exhibit "A" Extension in the form
     attached as Exhibit "A-2" for the applicable OEM Sublicensee; and (vi) any
     rights of any OEM Sublicensee sublicensed by OEM shall survive only so
     long as both the Agreement and the sublicense between OEM and such OEM
     Sublicensee remain in effect.  In connection with the foregoing, RSA
     further hereby grants to OEM a non-exclusive, non-transferable, non-
     assignable license during the term of this License/Product Schedule to use
     the RSA Source Code to provide support of Bundled Products to OEM
     Sublicensees.

     2.      New Versions.
             -------------

             a.  RSA agrees that the upgrade fees payable by OEM for any New
     Version pursuant to Section 4.3.3 with respect to Bundled Products covered
     by this License/Product Schedule shall be no less favorable than the
     upgrade fees for the same New Version paid by RSA's other similarly-
     situated OEMs.

             b.  RSA agrees that the upgrade fees payable by OEM for New
     Versions pursuant to Section 4.3.3 with respect to Bundled Products

                                        - 7 -                            54177.3

     covered by this License/Product Schedule shall not include any periodic
     License Fees in the nature of royalties.

                              MANDATORY SUBLICENSE TERMS

             All sublicense agreements for the license of the RSA Object Code
     in Bundled Products by OEM to OEM Sublicensees will include all of the
     following restrictions:

             I.  The OEM Sublicensee will receive no greater rights with
     respect to the Bundled Products than those permitted in Sections 2.2 of
     the Agreement as limited by Section 2.3 of the Agreement.

             II. The OEM Sublicensee will agree not to remove or destroy any
     proprietary, trademark or copyright markings or confidentiality legends
     placed upon or contained within the Bundled Products or any related
     materials or documentation.

             III.              If applicable, the OEM Sublicensee will agree
     that any sublicense of the Bundled Products to the United States
     Government or any agency thereof will state that such software is subject
     to limited rights in technical data and restricted rights applicable to
     commercial computer software developed entirely at private expense and
     that any associated documentation will include a restricted rights legend
     conforming to the Federal Acquisition Regulations (FARs) or the Department
     of Defense Federal Acquisition Regulations Supplement (DFARS), as
     applicable, then in effect that apply to software developed entirely at
     private expense.

             IV. The OEM Sublicensee will agree not to export or reexport any
     Bundled Products or any part thereof or information pertaining thereto any
     country for which a U.S. government agency requires an export license or
     other governmental approval without first obtaining such license or
     approval.

             V.  The OEM Sublicensee will agree that, except for the limited
     licenses granted under the license agreement, OEM and its licensors will
     retain full and exclusive right, title and ownership interest in and to
     the Bundled Products and in any and all related patents, trademarks,
     copyrights or proprietary or trade secret rights.

             VI. OEM will have the right to terminate the license for the OEM
     Sublicensee's breach of a material term.  The OEM Sublicensee will agree
     that, upon termination of the license, the OEM Sublicensee will return to
     OEM all copies of the object code and documentation for the Bundled
     Products or certify to OEM that the OEM Sublicensee has destroyed all such
     copies, except that the OEM Sublicensee may retain one (1) copy of the
     object code for the Bundled Products solely for the purpose of supporting
     the OEM Sublicensee's existing licensees.

             VII.              The OEM Sublicensee will agree not to reverse
     compile, disassemble or modify the Bundled Product.

             VIII.             The OEM Sublicensee will agree not to distribute
     the Bundled Product or any part thereof except pursuant to a license
     agreement meeting the requirements in Section 6.3 of the Agreement.

             IX.  The sublicense agreement will state that in no event will OEM
     or its licensors be liable for indirect, incidental, special,
     consequential or exemplary damages arising out of or related to the
     Bundled Product, including but not limited to lost profits, business
     interruption or loss of business information, even if such party has been
     advised of the possibility of such damages.

             This Conversion Agreement ("Agreement") is made and entered into
     between Virtual Open Network Environment Corporation, a Delaware
     corporation with its principal offices at 1803 Research Boulevard,
     Rockville, Maryland 20850 ("V-ONE"), RSA Data Security, Inc., a Delaware
     corporation, with its principal offices at 100 Marine Parkway, Redwood

                                       Recitals
                                       --------

             WHEREAS, V-ONE has granted to RSA the option to convert the right
     to receive future license fees under the BSAFE/TIPEM OEM Master License
     Agreement (No. 1294-VON-O-MLA-1), originally dated as of December 30, 1994
     and subsequently amended ("License Agreement"), between them into an
     equity interest in V-ONE, and

             WHEREAS, RSA has granted to MIT the right to receive 7.2% of the
     royalties received by RSA under the License Agreement, and
      
             WHEREAS, V-ONE proposes to issue to RSA 243,690 shares of its
     common stock, which number of shares is equal to 1.856% of V-ONE's
     currently issued and outstanding voting securities on an as-converted
     basis, and to issue to MIT 18,907 shares of its common stock, which number
     of shares is equal to 0.144% of V-ONE's currently issued and outstanding
     voting securities on an as-converted basis, and to deliver promptly a
     certificate representing such shares, and

             WHEREAS, V-ONE proposes to issue to RSA additional shares of its
     common stock equal to 1.856% of all additional issuances of voting
     securities, on an as-converted basis, that take place on or before the
     effective date of the registration statement for V-ONE's initial public
     offering, and to issue to MIT additional shares of its common stock equal
     to 0.144% of all additional issuances of voting securities, on an as-
     converted basis, that take place on or before the effective date of the
     registration statement for V-ONE's initial public offering, each issuance
     to be reduced by the number of any such shares that are repurchased by V-
     ONE prior to such effective date, and to deliver promptly a certificate or
     certificates representing such shares, and 

             WHEREAS, RSA desires to exercise its option to convert its right
     to receive future license fees under the License Agreement into an equity
     interest in V-ONE, and

             WHEREAS, RSA desires to receive shares of V-ONE common stock in
     satisfaction of V-ONE's obligation to pay future license fees to RSA, and
     to have V-ONE issue shares of V-ONE common stock to MIT in satisfaction of


                                        - 12 -                           54177.3

<PAGE>







     RSA's obligation to pay MIT 7.2% of the royalties received by RSA from V-
     ONE, and

             WHEREAS, MIT desires to receive shares of V-ONE common stock in
     satisfaction of RSA's obligation to pay MIT an amount of 7.2% of the
     royalties received by RSA from V-ONE;

             NOW, THEREFORE, in consideration of the covenants and agreements
     herein contained, and intending to be legally bound hereby, V-ONE, RSA and
     MIT agree as follows:

             1.  RSA exercises the option granted to RSA to convert the right
     to receive future license fees under the BSAFE/TIPEM OEM Master License
     Agreement (No. 1294-VON-O-MLA-1), originally dated as of December 30, 1994
     and subsequently amended, between them into an equity interest in V-ONE as
     of the date set forth below. 

             2.  V-ONE agrees to issue to RSA 243,690 shares of its common
     stock, which number of shares is equal to 1.856% of V-ONE's currently
     issued and outstanding voting securities on an as-converted basis, and to
     issue to MIT 18,907 shares of its common stock, which number of shares is
     equal to 0.144% of V-ONE's currently issued and outstanding voting
     securities on an as-converted basis, and to deliver promptly a certificate
     representing such shares.

             3.  V-ONE agrees to issue to RSA additional shares of its common
     stock equal to 1.856% of all additional issuances of voting securities, on
     an as-converted basis, that take place on or before the effective date of
     the registration statement for V-ONE's initial public offering, and to
     issue to RSA additional shares of its common stock equal to 0.144% of all
     additional issuances of voting securities, on an as-converted basis, that
     take place on or before the effective date of the registration statement
     for V-ONE's initial public offering, each issuance to be reduced by the
     number of any such shares that are repurchased by V-ONE prior to such
     effective date, and to deliver promptly a certificate or certificates
     representing such shares.

             4.  RSA is a key licensor to V-ONE.  MIT is a third party
     beneficiary of the License Agreement and this Agreement.  RSA and MIT are
     aware of V-ONE's business affairs and financial condition, are accredited
     investors for purposes of the Securities Act of 1933, as amended
     ("Securities Act"), and have acquired sufficient information about V-ONE
     to reach an informed and knowledgeable decision to exercise the conversion
     option and acquire the common stock as herein provided.  In making their
     decision, RSA and MIT are not relying on representations of any officer,
     director, stockholder or agent of the Company.  RSA is exercising the
     conversion option and acquiring the common stock for its own account for
     investment purposes only and not with a view to, or for the resale in
     connection with any "distribution" thereof for purposes of the Securities
     Act.  MIT is entering into this Agreement as a third party beneficiary of
     the License Agreement and this Agreement and is acquiring the common stock
     for its own account for investment purposes only and not with a view to,

                                        - 13 -                           54177.3

<PAGE>







     or for the resale in connection with any "distribution" thereof for
     purposes of the Securities Act. 

             5.  RSA and MIT understand and acknowledge that the common stock
     to be issued upon exercise of the conversion option will be issued
     pursuant to an exemption from the registration provisions of the
     Securities Act, that they may be required to hold such shares indefinitely
     unless subsequently registered under the Securities Act or unless an
     exemption from registration is otherwise available, that such common stock
     will be "restricted stock" as that term is defined in Rule 144 under the
     Securities Act and will be subject to that Rule, and that the certificates
     for such shares will be so legended.  RSA and MIT understand and
     acknowledge that V-ONE is under no obligation to register the common stock
     for sale under the Securities Act.

     V-ONE Series A Convertible  Preferred Stock ("Preferred Stock"),  valued at
     a price  of $3.00 per share, in exchange  for the Notes, and paying cash to

     Preferred Stock  to be  transferred to Investors  in exchange for  the Note
     and accrued interest thereon, and

                  WHEREAS,  V-ONE  proposes  to  offer  to those  Investors  who
     exchange their Notes for shares  of Preferred Stock, an  additional 333,333
     shares  of Preferred  Stock, at  a price  of  $3.00 per  share, based  upon

                  WHEREAS,  Investor  desires  to  receive  shares  of Preferred
     Stock in exchange  for the  Note, in repayment  of the  full amount of  the
     Note and the accrued interest thereon,  and to receive cash in lieu  of any

                    ----------------------------------------------

           3.1.   V-ONE Represents, Warrants and Covenants: 
                  -----------------------------------------

                  3.1.2.   The  authorized capital  stock of  V-ONE  consists of

     and nonassessable.   V-ONE has  reserved all 1,183,402  shares of Series  A
     Convertible  Preferred Stock  for  issuance  hereunder.    The  Common  and
     Preferred  Stock  shall  have  the  rights,   preferences,  privileges  and
     restrictions set forth in the Certificate.      

                  3.1.3.    All  corporate  action on  the  part  of V-ONE,  its
     directors and stockholders  necessary for the authorization,  execution and

     valid and binding  obligations of V-ONE, enforceable in accordance with its

     terms.  The  shares of Preferred Stock, when  issued in compliance with the
     provisions of  this Agreement, will be  validly issued, will  be fully paid
     and nonassessable,  and will  have the  rights, preferences and  privileges
     described  in  the  Certificate,   and  will  be  free  of  any   liens  or
     encumbrances, other  than any liens  or encumbrances created  by or imposed
     upon  Investor;  provided, however,  that  shares  of  Preferred Stock  are
     subject  to restrictions on transfer under  state and/or federal securities
     laws as set forth herein.   The shares of  Preferred Stock are not  subject
     to any preemptive rights or rights of first refusal.

                  3.1.4.   V-ONE makes  no representation or warranty  as to the
     minimum amount of  any subscription or  capital investment  it may  require
     and reserves the  right to treat the  shares of Preferred Stock  as finally
     sold and  to retain  the purchase price  for the  Preferred Stock  provided
     herein without regard to the amount of subscriptions.

           3.2.   Investor Represents, Warrants and Covenants: 
                  --------------------------------------------

                  3.2.1.    Investor  represents  that no  events have  occurred
     since  the date  of  the Purchase  Agreement  that have  altered Investor's
     representation that he or she was an accredited investor at that time,  and
     Investor  is,  and remains,  an  accredited  investor,  as  defined in  the
     federal securities laws. 

                  3.2.2.    Investor  acknowledges  that  he  or  she  has  been
     provided with  and  has carefully  read a  copy  of the  V-ONE  Corporation
     Business Plan dated  March 1996, V-ONE's 1995 Annual Report, balance sheets
     of V-ONE as  of December 31,  1994 and 1995  and the related statements  of
     operations,  stockholders'  equity  and cash  flows  for  the  period  from
     February  16, 1993 (date  of inception)  to December  31, 1993 and  for the
     years ended December  31, 1994 and 1995,  and unaudited balance sheets  for
     January  and February  of  1996 ("Financial  Statements"),  and a  copy the
     Certificate  of   Designation,  Preferences,   and  Rights   of  Series   A
     Convertible Preferred Stock of V-ONE.

                  3.2.3.    Investor represents and  affirms that he  or she has
     prior  investment   experience,  including   investments  in   unregistered
     securities, recognizes  the highly  speculative nature  of this  investment
     and is able to bear the economic risk of such an investment.
                  3.2.4.   The shares of Preferred Stock are being purchased for
     Investor's own account, for  investment purposes only, and not with  a view

     attorney, or  accountant with respect to this  matter and has willingly and
     consciously chosen not to seek such advice.

                  3.2.7.   Investor and his or  her investment adviser, attorney
     and accountant,  if any,  have been  furnished, during the  course of  this

                  "RESTRICTED  SECURITIES" shall  mean the  securities  of V-ONE
     required to bear the legend in Section 4.3.

                  "SECURITIES ACT" shall  mean the  Securities Act  of 1933,  as

     be stamped or  otherwise imprinted with a legend  in the following form (in
     addition to any  legend required under any other agreement between Investor

                  THE SHARES  REPRESENTED BY  THIS CERTIFICATE  HAVE
                  BEEN  ACQUIRED  FOR  INVESTMENT  AND  ARE  NOT THE
                  SUBJECT OF  A  REGISTRATION  STATEMENT  UNDER  THE
                  SECURITIES ACT  OF 1933.  SUCH SHARES  MAY NOT  BE
                  SOLD   OR  TRANSFERRED  IN  THE  ABSENCE  OF  SUCH
                  REGISTRATION   UNLESS  THE   COMPANY  RECEIVES  AN
                  OPINION  OF COUNSEL  REASONABLY ACCEPTABLE  TO  IT
                  STATING THAT SUCH SALE OR TRANSFER IS  EXEMPT FROM
                  THE REGISTRATION REQUIREMENTS OF SAID ACT.

           Investor  consents to  V-ONE making  a  notation  on its  records and
     giving instructions to  any transfer agent of the  Preferred Stock in order
     to implement the restrictions on transfer established in this Section 4.

           4.4.   The  holder of  Restricted  Securities  by acceptance  thereof
     agrees to comply in  all respects with the provisions of this  Section 4.4.
     Prior  to  any  proposed  sale,  assignment,  transfer  or  pledge  of  any
     Restricted  Securities (other than (i) a transfer not involving a change in
     beneficial  ownership,  (ii)  in  transactions involving  the  distribution
     without consideration  of Restricted Securities  by Investor to  any of its
     partners, or  retired partners or to the  estate of any of  its partners or
     retired partners,  or (iii) in  transactions in compliance  with Rule 144),
     and  unless  there   is  in  effect  a  registration  statement  under  the
     Securities  Act covering  the proposed  transfer, the  holder thereof shall
     give  written notice  to V-ONE of  such holder's  intention to  effect such
     transfer, sale, assignment or pledge.  Each  such notice shall describe the
     manner  and circumstances  of the  proposed transfer,  sale,  assignment or
     pledge in sufficient  detail, and shall  be accompanied,  at such  holder's
     expense by either (i) a  written opinion of legal counsel who shall be, and
     whose legal opinion shall  be, reasonably  satisfactory to V-ONE  addressed
     to  V-ONE, to  the  effect that  the  proposed transfer  of  the Restricted
     Securities may be  effected without registration under the  Securities Act,
     or (ii)  a "no action"  letter from the Commission  to the effect  that the
     transfer  of such  securities  without registration  will  not result  in a
     recommendation by the  staff of the  Commission that  action be taken  with
     respect  thereto, whereupon the holder of  such Restricted Securities shall
     be entitled to transfer such  Restricted Securities in accordance  with the

                                        - 6 -

<PAGE>







     terms  of the notice  delivered by  the holder  to V-ONE.   Any certificate
     evidencing the  Restricted Securities transferred  as above provided  shall
     bear,  except  if  such  transfer   is  made  pursuant  to  Rule  144,  the
     appropriate restrictive legend  set forth in Section 4.3 above, except that
     such  certificate shall not bear such  restrictive legend if in the opinion
     of counsel for such holder and V-ONE  such legend is not required in  order
     to establish compliance with any provision of the Securities Act.

           4.5.   Registration Right.
                  ------------------

           (a)    Demand Registration Right on Two Occasions
                  ------------------------------------------

                  (i)  Pursuant   to  this  Section  4.5,   V-ONE  will  provide
     Investors  as  a  group   and  not  individually,  subject  to  underwriter
     approval,  with a  right to  register Registration  Shares in  underwritten
     offerings on two occasions.  Investor may  exercise this right at any  time
     commencing the  date  of Closing  and  ceasing  on the  second  anniversary
     thereof, unless  the holding  period under  Rule 144 shall  be shorter,  by
     giving  notice to  V-ONE  that Investor  desires  to have  the Registration
     Shares registered for sale under the Securities Act.  Upon receipt of  such
     notice,  on  two  and  only  two  occasion,  V-ONE  promptly  will  file  a
     registration statement  with the Commission so that the Registration Shares
     may be publicly  sold as promptly  as practical thereafter  and V-ONE  will
     use its  best efforts to cause  such registration statement to  be declared
     effective by the Commission promptly. 

                  (ii)  Within ten days  after receiving any such  notice, V-ONE
     shall give notice to  all other Investors advising that V-ONE is proceeding
     with such  registration statement  and offering  to include  shares of  the
     other Investors provided that they notify V-ONE within  ten days of receipt
     of such  notice that  they desire  to have  their shares  included in  such
     registration rights.

                  (iii)  If Form  S-3 (or  its successor)  is available  for the
     offering  of the  Registration  Shares,  then  V-ONE will,  promptly  after
     receipt of  such notice  from Investor,  file a  registration statement  on
     Form S-3 under  the same procedures set forth above  and shall use its best
     efforts to  cause such registration  statement to be  declared effective by
     the Commission and to remain effective for a period of one year.

                  (iv)  In  connection   with  such  underwriting,  V-ONE  shall
     execute an appropriate underwriting agreement in  customary form and supply
     prospectuses to the Investors  and shall use  its best efforts to  register
     and  qualify  the  Registration Shares  for  sale  in  such  states as  the
     Investors shall reasonably  request ("States").  The  two-time registration
     right provided for in this Section 4.5  shall not be deemed to be satisfied
     if  V-ONE  (alone  and  not in  conjunction  with  a  determination by  the
     managing underwriter)  unilaterally determines not  to include any  portion
     of the  Registration Shares in  a registration statement  filed pursuant to
     this Section.

<PAGE>







                  (v)   V-ONE shall bear all expenses relating to the filing  of
     a  registration  statement  relating to  the  Registration  Shares  and the
     States, except  for underwriting  discounts or  commissions and shall  have
     the  right  to  approve  any  underwriter,  investment  broker  or  adviser
     retained by  an  Investor to  effect  a  distribution of  the  Registration
     Shares,   which    approval   shall   not    be   unreasonably    withheld.
     Notwithstanding anything  to  the  contrary set  forth  herein,  V-ONE  may
     postpone the  filing of  the registration  statement for  a  period not  to
     exceed ninety  days  if  the  postponement  will  avoid  the  necessity  of
     preparing audited financial  statements as of a date  other than the end of
     a fiscal year  or the Chief Executive  Officer of V-ONE determines  in good
     faith that the postponement  is necessary to  avoid serious jeopardy to  V-
     ONE, any significant  business prospect of V-ONE or the security holders of
     V-ONE considered as a group.

           (b)    Piggyback Registration Rights.
                  ------------------------------

                  (i)   If V-ONE  determines that  it will  file a  registration
     statement, at any time  after the date of Closing, for any  public offering
     of shares  of Preferred Stock, either for its own account or the account of
     any security  holder, V-ONE shall give written  notice to all Investors, at
     least (30)  days in  advance of  filing such  registration statement,  that
     such filing  is expected to be  made.  Upon the  written request of  any of
     the Investors received  by V-ONE at least  fifteen (15) days in  advance of
     the  filing, and  subject to  the  limitations set  forth  in this  Section
     4.5(b), V-ONE  shall include  in such  registration statement  Registration
     Shares for the purpose of registering such Registration Shares for sale  by
     or for the account of such Investors.

                  (ii)  V-ONE  shall have  exclusive  control  over the  filing,
     amending,  withdrawal  and   other  actions  regarding   such  registration
     statement.  V-ONE shall  have no obligation to give notice to any Investors
     with respect to the  filing of, or to include any  shares for any Investors
     in, any registration statement on Form S-4 or  Form S-8 (or successor forms
     thereto) or on any  other form that does not include substantially the same
     information  or  is not  in  substantially  the  same format  as  would  be
     required for a registration statement for a sale of shares by Investors. 

                                      SECTION 5

                                    Miscellaneous
                                    -------------

           5.1.   Notwithstanding  the   place  where  this   Agreement  may  be
     executed by  Investor,  all  the  terms  and  provisions  hereof  shall  be
     construed  in accordance  with and  governed by  the internal  laws  of the
     State of Delaware.

           5.2.   This Agreement  constitutes the  entire agreement  of Investor
     and V-ONE with  respect to  the subject matter  hereof and  may be  amended
     only by a writing  executed by  Investor and V-ONE.   This Agreement  shall

     inure  to the benefit of and be binding upon each of the parties hereto and
     their respective heirs and legal representatives.

           5.3.   Neither this Agreement nor any  term or provision hereof shall
     be modified, changed, discharged or  terminated except by an  instrument in
     writing  signed  by  the  party  against  whom  any  modification,  change,
     discharge or termination is sought to be enforced.

           5.4.   This Agreement and  the rights provided for herein may  not be
     transferred or  assigned by  Investor.   Any attempted  assignment of  this
     Agreement shall be null  and void.  All rights and obligations  of Investor
     shall  survive  Investor's  death,  permanent  incapacitation,  bankruptcy,
     insolvency or dissolution.

     representing Warrant  Shares shall,  except as otherwise  provided in  this
     Section 2 or in Section 3,  be stamped or otherwise imprinted with a legend
     substantially in the following form:  

                               "THIS  SECURITY  HAS NOT  BEEN REGISTERED
                      UNDER  THE SECURITIES  ACT OF  1933 OR  ANY STATE
                      SECURITIES LAWS AND MAY NOT BE TRANSFERRED UNLESS
                      SUCH SALE  OR TRANSFER IS IN  ACCORDANCE WITH THE
                      REGISTRATION REQUIREMENTS OF  THE SECURITIES  ACT
                      OF  1933 AND APPLICABLE STATE  SECURITIES LAWS OR
                      SOME  OTHER  EXEMPTION   FROM  THE   REGISTRATION
                      REQUIREMENTS  OF THE  SECURITIES ACT OF  1933 AND
                      APPLICABLE  STATE  SECURITIES  LAWS  IS AVAILABLE
                      WITH RESPECT THERETO,  AS DEMONSTRATED BY OPINION
                      OF COUNSEL SATISFACTORY TO THE COMPANY.

     A certificate  shall not  bear such  legend if  in the  opinion of  counsel
     satisfactory  to  the  Company  (it  being  agreed  that  Testa,  Hurwitz &
     Thibeault, LLP  shall be satisfactory)  the securities represented  thereby
     may be publicly sold without registration under  the Securities Act and any
     applicable state securities laws.

                      3.       Notice  of  Proposed  Transfer.    Prior  to  any
     proposed   transfer  of   any  Warrant   Shares  (other   than  under   the
     circumstances described  in Sections 4, 5  or 6), the  holder thereof shall
     give  written  notice  to the  Company  of  its  intention to  effect  such
     transfer.   Each  such  notice shall  describe the  manner of  the proposed
     transfer  and, if  requested by  the  Company, shall  be accompanied  by an
     opinion of  counsel  satisfactory to  the  Company  (it being  agreed  that
     Testa, Hurwitz & Thibeault, LLP shall  be satisfactory) to the  effect that
     the  proposed transfer  may  be  effected  without registration  under  the
     Securities Act  and any  applicable state  securities  laws, whereupon  the
     holder  of  such  stock  shall  be  entitled  to  transfer  such  stock  in
     accordance  with the terms  of its  notice.   Each certificate  for Warrant
     Shares transferred  as above provided  shall bear the  legend set  forth in
     Section 2,  except that  such  certificate shall  not  bear such  legend if
     (i) such transfer is in accordance with the provisions  of Rule 144 (or any
     other  rule   permitting  public  sale   without  registration  under   the
     Securities Act) or (ii) the  opinion of counsel referred to above is to the
     further  effect that the  transferee and  any subsequent  transferee (other
     than  an affiliate  of  the Company)  would  be entitled  to  transfer such
     securities in a  public sale without registration under the Securities Act.
     The restrictions  provided  for  in  this  Section 3  shall  not  apply  to
     securities  that  are  not  required  to  bear  the  legend  prescribed  by
     Section 2 in accordance with the provisions of that Section.

                      4.       Required  Registration.   (a)  At any  time after
     six months after any registration  statement covering a public  offering of

<PAGE>







                          Registration Rights Agreement - 3

     securities of  the  Company under  the  Securities  Act shall  have  become
     effective,  Purchaser  may  request  the  Company  to  register  under  the
     Securities Act all  or any portion of  the shares of Restricted  Stock held
     by Purchaser  for sale  in the  manner specified  in such  notice, provided
     that  the reasonably  anticipated  aggregate price  to  the public  of such
     public offering  would exceed  $500,000.   Notwithstanding anything to  the
     contrary contained  herein, no  request may  be made  under this  Section 4
     within 120 days after  the effective date of a registration statement filed
     by the Company covering a  firm commitment underwritten public  offering in
     which the holders  of Restricted  Stock shall  have been  entitled to  join
     pursuant to Sections 5 or 6 and in which there shall have been  effectively
     registered all  shares of Restricted  Stock as to  which registration shall
     have been requested.  

                      (b)   Following  receipt  of any  notice  under this  Sec-
     tion 4, the  Company  shall immediately  notify all  holders of  Restricted
     Stock  from  whom notice  has  not been  received  and shall  use  its best
     efforts  to  register   under  the  Securities  Act,  for  public  sale  in
     accordance with the  method of disposition  specified in  such notice  from
     requesting holders, the number of  shares of Restricted Stock  specified in
     such notice (and in all notices received by  the Company from other holders
     within 30 days  after the giving of such  notice by the Company).   If such
     method  of disposition  shall  be  an  underwritten  public  offering,  the
     holders of a  majority of the shares of Restricted Stock to be sold in such
     offering  may designate the managing  underwriter of such offering, subject
     to the approval  of the Company,  which approval shall not  be unreasonably
     withheld  or  delayed.     The  Company  shall  be  obligated  to  register
     Restricted  Stock  pursuant  to  this  Section 4   on  one  occasion  only,
     provided,  however,  that such  obligation shall  be deemed  satisfied only
     when  a registration  statement  covering all  shares  of Restricted  Stock
     specified in notices  received as aforesaid,  for sale  in accordance  with
     the method of disposition specified  by the requesting holders,  shall have
     become effective  and, if such method  of disposition is  a firm commitment
     underwritten  public  offering,  all  such  shares  shall  have  been  sold
     pursuant thereto  (other than  shares,  if any,  that may  be sold  in  the
     underwriters' overallotment option).  

                      (c)   The  Company  shall be  entitled  to include  in any
     registration  statement  referred  to  in  this  Section 4,  for  sale   in
     accordance with  the  method of  disposition  specified by  the  requesting
     holders, shares  of Common  Stock to  be sold  by the Company  for its  own
     account, except  as and to the extent that,  in the opinion of the managing
     underwriter (if such  method of disposition shall be an underwritten public
     offering),  such  inclusion would  adversely  affect the  marketing  of the
     Restricted  Stock  to be  sold.    Except  for  registration statements  on
     Form S-4,  S-8, a  combination  S-8/S-3 relating  to  the resale  of shares
     issued under a stock plan only, or any successor thereto, the Company  will
     not file with  the Commission any other registration statement with respect
     to  its  Common  Stock,  whether for  its  own  account  or  that of  other
     stockholders, from the date  of receipt of a notice from requesting holders
     pursuant  to  this   Section 4  until  the  completion  of  the  period  of
     distribution of the registration contemplated thereby.

                          Registration Rights Agreement - 4

                      5.       Incidental Registration.   If the  Company at any
     time (other  than pursuant to  Section 4 or Section 6  or in the  Company's
     initial public offering) proposes to  register any of its  securities under
     the Securities Act for sale to the  public, whether for its own account  or
     for the account  of other security holders or  both (except with respect to
     registration statements on  Forms S-4, S-8, a combination  S-8/S-3 relating
     to the resale of  shares issued under  a stock plan  only, or another  form
     not available  for  registering  the  Restricted  Stock  for  sale  to  the
     public), each such time  it will give written notice to all holders of out-
     standing Restricted Stock  of its  intention so to  do.   Upon the  written
     request of  any such holder, received  by the Company  within 30 days after
     the giving  of any  such notice  by the  Company, to  register  any of  its
     Restricted  Stock, the  Company will  use  its best  efforts  to cause  the
     Restricted  Stock as to which registration  shall have been so requested to
     be included in  the securities to be covered  by the registration statement
     proposed to be filed by the Company, all to the extent requisite to  permit
     the sale or other  disposition by  the holder of  such Restricted Stock  so
     registered.  In the event that any  registration pursuant to this Section 5
     shall be, in  whole or in part,  an underwritten public offering  of Common
     Stock, the  number of shares of Restricted Stock to  be included in such an
     underwriting may  be reduced (pro  rata among the  requesting holders based
     upon  the number of  shares of Restricted Stock  owned by  such holders) if
     and to the extent  that the  managing underwriter shall  be of the  opinion
     that such inclusion  would adversely affect the marketing of the securities
     to be sold by the Company therein,  provided, however, that such number  of
     shares  of Restricted Stock  shall not be reduced  if any shares  are to be
     included in such underwriting for the account of  any person other than the
     Company or  requesting holders  of Restricted  Stock.  Notwithstanding  the
     foregoing provisions, the  Company may withdraw any  registration statement
     referred to  in this Section 5  without thereby incurring  any liability to
     the holders of Restricted Stock.  

                      6.       Registration on  Form S-3.  If at  any time (i) a
     holder  or holders of at least 20%  of the total shares of Restricted Stock
     then outstanding request  that the Company file a registration statement on
     Form S-3 or  any successor  thereto for  a public  offering of  all or  any
     portion of the  shares of Restricted  Stock held by such  requesting holder
     or holders, the  reasonably anticipated aggregate  price to  the public  of
     which would exceed  $500,000, and (ii) the Company is a registrant entitled
     to use Form S-3 or  any successor thereto to register such shares, then the
     Company shall use its best efforts to register under the Securities Act  on
     Form S-3 or  any successor thereto, for public  sale in accordance with the
     method of  disposition specified in  such notice,  the number of  shares of
     Restricted  Stock  specified in  such  notice.    Whenever  the Company  is
     required  by  this  Section 6  to  use  its  best  efforts  to  effect  the
     registration of Restricted  Stock, each of the procedures  and requirements
     of  Section 4  (including but  not  limited  to  the  requirement that  the
     Company  notify all holders  of Restricted  Stock from whom  notice has not
     been received and provide them  with the opportunity to participate  in the
     offering)  shall apply to such registration,  provided, however, that there
     shall be  no limitation on  the number of  registrations on Form S-3  which
     may be requested  and obtained under this Section 6, and provided, further,

<PAGE>







                          Registration Rights Agreement - 5

     however,  that  the  requirements  contained  in   the  first  sentence  of
     Section 4(a) shall not apply  to any registration on Form S-3 which  may be
     requested and obtained under this Section 6.  

                      7.       Registration  Procedures.    If and  whenever the
     Company is required  by the provisions  of Sections 4,  5 or 6  to use  its
     best efforts to effect  the registration of any shares of  Restricted Stock
     under the Securities Act, the  Company will, as expeditiously  as possible:

                      (a)  prepare  and file with the Commission  a registration
     statement (which, in the case  of an underwritten public  offering pursuant
     to Section 4, shall be  on Form S-1 or other form of  general applicability
     satisfactory  to the  managing underwriter  selected  as therein  provided)
     with  respect to such  securities and  use its  best efforts to  cause such
     registration statement to  become and remain  effective for  the period  of
     the   distribution   contemplated   thereby   (determined  as   hereinafter
     provided);  

                      (b)  prepare and file with  the Commission such amendments
     and supplements to such registration  statement and the prospectus  used in
     connection  therewith  as  may  be  necessary  to  keep  such  registration
     statement effective  for the period  specified in  paragraph (a) above  and
     comply  with the  provisions  of the  Securities  Act with  respect  to the
     disposition of all Restricted Stock covered  by such registration statement
     in accordance  with the sellers'  intended method of  disposition set forth
     in such registration statement for such period;  

                      (c)  furnish  to each seller  of Restricted  Stock and  to
     each underwriter  such number of  copies of the  registration statement and
     the prospectus included therein (including each  preliminary prospectus) as
     such persons reasonably may request in order to facilitate the  public sale
     or other disposition of the  Restricted Stock covered by  such registration
     statement;  

                      (d)   use  its  best efforts  to  register or  qualify the
     Restricted  Stock  covered   by  such  registration  statement   under  the
     securities or  "blue sky"  laws  of such  jurisdictions as  the sellers  of
     Restricted  Stock or, in the  case of an  underwritten public offering, the
     managing underwriter reasonably shall request, provided,  however, that the
     Company shall not for  any such purpose be required to qualify generally to
     transact business as a foreign corporation in any  jurisdiction where it is
     not so qualified  or to consent to  general service of process  in any such
     jurisdiction;  

                      (e)      use its best efforts to list the Restricted Stock
     covered  by such  registration statement  with any  securities exchange  on
     which the Common Stock of the Company is then listed; 

                      (f)      immediately  notify  each  seller  of  Restricted
     Stock and each underwriter under  such registration statement, at  any time
     when a  prospectus relating thereto is  required to be delivered  under the
     Securities Act, of  the happening  of any event  of which  the Company  has

<PAGE>







                          Registration Rights Agreement - 6

     knowledge  as  a  result  of   which  the  prospectus  contained   in  such
     registration statement, as  then in effect, includes an untrue statement of
     a material fact  or omits to  state a material fact  required to be  stated
     therein  or necessary  to  make the  statements  therein not  misleading in
     light of the circumstances then existing;  

                      (g)      if  the  offering  is  underwritten  and  at  the
     request of any seller of Restricted Stock, use its best efforts to  furnish
     on  the date  that Restricted  Stock is  delivered to  the underwriters for
     sale pursuant to  such registration:   (i) an  opinion dated  such date  of
     counsel  representing the  Company for  the purposes  of such registration,
     addressed  to  the underwriters  and  to  such  seller,  stating that  such
     registration  statement has become effective  under the  Securities Act and
     that  (A) to the best  knowledge of such counsel,  no stop order suspending
     the effectiveness thereof has been issued and no proceedings for that  pur-
     pose have  been  instituted  or  are  pending  or  contemplated  under  the
     Securities Act, (B) the registration statement, the  related prospectus and
     each amendment  or supplement  thereof comply  as to form  in all  material
     respects with  the requirements  of the  Securities Act  (except that  such
     counsel need not  express any opinion as to financial statements, schedules
     and  other financial  and  statistical data  contained therein)  and (C) to
     such  other  effects as  reasonably  may be  requested  by counsel  for the
     underwriters or by such seller or its counsel and (ii) a letter dated  such
     date  from the  independent  public accountants  retained  by the  Company,
     addressed to  the underwriters  and to such  seller, stating that  they are
     independent  public accountants within  the meaning  of the  Securities Act
     and that, in the opinion  of such accountants, the financial  statements of
     the Company  included in the  registration statement or  the prospectus, or
     any amendment  or supplement  thereof, comply  as to form  in all  material
     respects  with the  applicable accounting  requirements  of the  Securities
     Act, and such  letter shall additionally cover such other financial matters
     (including information as to  the period ending no more  than five business
     days prior to  the date of such  letter) with respect to  such registration
     as such underwriters reasonably may request; and  

                      (h)      make available  for inspection by  each seller of
     Restricted  Stock,   any  underwriter  participating  in  any  distribution
     pursuant  to such  registration statement, and  any attorney, accountant or
     other  agent retained  by  such seller  or  underwriter, all  financial and
     other  records,  pertinent  corporate  documents  and   properties  of  the
     Company,  and  cause the  Company's  officers, directors  and  employees to
     supply  all   information  reasonably   requested  by   any  such   seller,
     underwriter,  attorney,  accountant  or  agent  in   connection  with  such
     registration statement.  

                      For  purposes  of  Section 7(a)  and  7(b)   and  of  Sec-
     tion 4(c),  the  period of  distribution  of  Restricted  Stock  in a  firm
     commitment underwritten public  offering shall  be deemed  to extend  until
     each  underwriter  has   completed  the  distribution  of   all  securities
     purchased by it, and the period of distribution of Restricted Stock in  any
     other registration shall be deemed to extend until  the earlier of the sale

<PAGE>







                          Registration Rights Agreement - 7

     of all Restricted  Stock covered thereby  and 90 days  after the  effective
     date thereof.  

                      In connection with each  registration hereunder, the  sel-
     lers  of Restricted  Stock  will furnish  to  the Company  in writing  such
     information with  respect to  themselves and  the proposed distribution  by
     them as  reasonably shall be necessary  in order to assure  compliance with
     federal and applicable state securities laws.  

                      In  connection  with each  registration  pursuant to  Sec-
     tions 4, 5 or 6 covering an  underwritten public offering, the Company  and
     each  seller agree  to enter  into a  written agreement  with  the managing
     underwriter  selected  in the  manner  herein  provided  in  such form  and
     containing such provisions  as are customary in the securities business for
     such  an  arrangement  between  such  underwriter   and  companies  of  the
     Company's  size  and  investment  stature;  provided,   however,  that  the
     provisions of such agreement whereby  each seller shall agree  to indemnify
     other parties  to such agreement  shall not exceed  or be broader in  scope
     than the indemnification set forth in Section 9(b) hereof.  

                      8.       Expenses.   All expenses incurred  by the Company
     in complying with Sections 4, 5  and 6, including, without  limitation, all
     registration and filing fees,  printing expenses, fees and disbursements of
     counsel  and  independent public  accountants  for  the Company,  fees  and
     expenses (including  counsel fees)  incurred in  connection with  complying
     with state securities or "blue sky" laws, fees of the National  Association
     of Securities  Dealers, Inc., transfer  taxes, fees of  transfer agents and
     registrars, costs  of insurance and  fees and disbursements  of one counsel
     for the  sellers of Restricted  Stock, but excluding  any Selling Expenses,
     are  called  "Registration  Expenses."    All  underwriting  discounts  and
     selling commissions applicable to the  sale of Restricted Stock  are called
     "Selling Expenses."  

                      The Company  will pay  all Registration  Expenses in  con-
     nection with  each registration statement  under Sections 4, 5  or 6.   All
     Selling  Expenses in  connection  with  each registration  statement  under
     Sections 4,  5  or  6  shall  be  borne  by  the participating  sellers  in
     proportion to the  number of shares sold by  each, or by such participating
     sellers other than the  Company (except to the extent the Company  shall be
     a seller) as they may agree.  

                      9.       Indemnification and  Contribution.   (a)  In  the
     event  of  a  registration  of  any  of  the  Restricted  Stock  under  the
     Securities Act pursuant to Sections 4, 5  or 6, the Company will  indemnify
     and hold harmless  each seller of  such Restricted  Stock thereunder,  each
     underwriter of such Restricted Stock  thereunder and each other  person, if
     any, who  controls such  seller or  underwriter within  the meaning of  the
     Securities Act,  against any losses, claims,  damages or liabilities, joint
     or several, to  which such seller,  underwriter or  controlling person  may
     become  subject under  the  Securities Act  or  otherwise, insofar  as such
     losses,  claims, damages  or liabilities  (or actions  in respect  thereof)
     arise out  of or  are based  upon any  untrue statement  or alleged  untrue

     statement  of any  material fact  contained in  any registration  statement
     under which such Restricted Stock  was registered under the  Securities Act
     pursuant  to  Sections 4, 5  or  6,  any  preliminary  prospectus or  final
     prospectus  contained therein, or any  amendment or  supplement thereof, or
     arise out of or  are based upon the  omission or alleged omission to  state
     therein a material fact required to be stated  therein or necessary to make
     the  statements  therein  not  misleading,  and will  reimburse  each  such
     seller, each  such underwriter  and each  such controlling  person for  any
     legal or  other expenses  reasonably incurred  by them  in connection  with
     investigating  or defending  any  such loss,  claim,  damage, liability  or
     action, provided, however, that the Company will not be liable in any  such
     case if and to  the extent that any such  loss, claim, damage or  liability
     arises  out of  or  is based  upon an  untrue  statement or  alleged untrue
     statement or  omission  or alleged  omission  so  made in  conformity  with
     information furnished by any such seller, any such underwriter or any  such
     controlling person  in writing  specifically for  use in  such registration
     statement or prospectus.  

                      (b)      In  the event  of a  registration  of any  of the
     Restricted Stock  under the Securities Act pursuant  to Sections 4, 5 or 6,
     each  seller  of  such  Restricted  Stock  thereunder,  severally  and  not
     jointly, will  indemnify and  hold harmless  the Company,  each person,  if
     any, who controls  the Company within  the meaning of  the Securities  Act,
     each officer  of the  Company who  signs the  registration statement,  each
     director of the Company, each underwriter and each person  who controls any
     underwriter within the meaning of  the Securities Act, against  all losses,
     claims, damages or liabilities, joint  or several, to which the  Company or
     such  officer,  director,  underwriter or  controlling  person  may  become
     subject under  the Securities  Act or  otherwise, insofar  as such  losses,
     claims, damages  or liabilities (or  actions in respect  thereof) arise out
     of or are  based upon any untrue  statement or alleged untrue  statement of
     any material fact  contained in the registration statement under which such
     Restricted  Stock  was registered  under  the  Securities Act  pursuant  to
     Sections 4,  5  or  6,  any  preliminary  prospectus  or  final  prospectus
     contained therein, or any amendment or supplement  thereof, or arise out of
     or are  based upon  the omission  or alleged  omission to  state therein  a
     material  fact  required to  be  stated therein  or necessary  to  make the
     statements therein not  misleading, and will reimburse the Company and each
     such officer, director,  underwriter and  controlling person for  any legal
     or  other  expenses  reasonably   incurred  by  them  in   connection  with
     investigating  or  defending any  such  loss, claim,  damage,  liability or
     action, provided, however,  that such seller  will be  liable hereunder  in
     any such case if  and only to the extent that any such  loss, claim, damage
     or liability arises out of or is based upon an  untrue statement or alleged
     untrue statement or omission or  alleged omission made in reliance upon and
     in  conformity  with  information  pertaining  to  such  seller,  as  such,
     furnished in writing to the Company by such seller specifically for use  in
     such registration statement or prospectus, and  provided, further, however,
     that the liability  of each seller hereunder  shall be limited to  the pro-
     portion  of any  such loss, claim,  damage, liability  or expense  which is
     equal to the proportion  that the public offering price of the  shares sold
     by such seller under such registration statement bears  to the total public

<PAGE>







                          Registration Rights Agreement - 9

     offering price of all securities sold thereunder,  but not in any event  to
     exceed the  proceeds received by  such seller from  the sale of  Restricted
     Stock covered by such registration statement.  

                      (c)      Promptly  after receipt  by an  indemnified party
     hereunder of notice  of the commencement  of any  action, such  indemnified
     party  shall, if  a claim  in respect  thereof is  to be  made  against the
     indemnifying  party hereunder,  notify the  indemnifying  party in  writing
     thereof, but the  omission so  to notify the  indemnifying party shall  not
     relieve it from any liability which it  may have to such indemnified  party
     other  than  under  this Section 9  and  shall  only  relieve  it from  any
     liability which it may have  to such indemnified party under this Section 9
     if  and  to  the  extent the  indemnifying  party  is  prejudiced  by  such
     omission.    In  case  any  such  action  shall  be   brought  against  any
     indemnified  party  and it  shall  notify  the  indemnifying  party of  the
     commencement thereof,  the indemnifying  party shall be  entitled to parti-
     cipate in  and, to the  extent it shall  wish, to assume  and undertake the
     defense thereof with counsel satisfactory  to such indemnified party,  and,
     after notice from the indemnifying  party to such indemnified party of  its
     election so to assume and  undertake the defense thereof,  the indemnifying
     party shall not be  liable to such  indemnified party under this  Section 9
     for any legal expenses subsequently  incurred by such indemnified  party in
     connection  with  the  defense  thereof  other  than  reasonable  costs  of
     investigation and of  liaison with counsel so selected,  provided, however,
     that, if  the defendants  in any such  action include both  the indemnified
     party  and the  indemnifying  party and  the  indemnified party  shall have
     reasonably concluded that  there may be reasonable defenses available to it
     which  are  different   from  or  additional  to  those  available  to  the
     indemnifying party or  if the interests of the indemnified party reasonably
     may  be deemed  to conflict with  the interests of  the indemnifying party,
     the indemnified party  shall have  the right to  select a separate  counsel
     and  to assume  such legal  defenses  and otherwise  to participate  in the
     defense  of such  action,  with the  expenses  and  fees of  such  separate
     counsel and other expenses related  to such participation to  be reimbursed
     by the indemnifying party as incurred.  

                      (d)      In  order  to  provide  for  just  and  equitable
     contribution to joint  liability under the  Securities Act  in any case  in
     which either (i) any  holder of  Restricted Stock  exercising rights  under
     this  Agreement, or  any controlling  person of  any such  holder, makes  a
     claim for indemnification pursuant to  this Section 9 but it  is judicially
     determined (by  the entry  of  a final  judgment or  decree by  a court  of
     competent jurisdiction and the  expiration of time to appeal  or the denial
     of the last right of appeal) that such indemnification may not be  enforced
     in such  case notwithstanding  the fact  that this  Section 9 provides  for
     indemnification in  such case,  or (ii) contribution  under the  Securities
     Act may  be required  on the part  of any such  selling holder or  any such
     controlling person in  circumstances for which indemnification  is provided
     under  this Section 9; then,  and in each such  case, the  Company and such
     holder  will  contribute  to  the  aggregate  losses,  claims,  damages  or
     liabilities to which they may  be subject (after contribution  from others)
     in  such  proportion so  that such  holder is  responsible for  the portion

                          Registration Rights Agreement - 10

     represented  by  the percentage  that  the  public  offering  price of  its
     Restricted Stock offered  by the registration statement bears to the public
     offering price of  all securities  offered by such  registration statement,
     and  the  Company  is  responsible  for  the  remaining  portion; provided,
     however, that, in any  such case,  (A) no such holder  will be required  to
     contribute any amount  in excess of the  public offering price of  all such
     Restricted Stock  offered by  it pursuant  to such  registration statement;
     and  (B) no person or entity guilty of fraudulent misrepresentation (within
     the meaning of  Section 11(f) of  the Securities Act)  will be entitled  to
     contribution  from  any  person  or  entity  who  was  not  guilty of  such
     fraudulent misrepresentation.  

                      10.      Changes  in Common  Stock.  If, and  as often as,
     there  is any change  in the Common  Stock by way  of a  stock split, stock
     dividend,   combination  or   reclassification,   or  through   a   merger,
     consolidation, reorganization or  recapitalization, or by any  other means,
     appropriate  adjustment shall be made in the  provisions hereof so that the
     rights and privileges  granted hereby shall  continue with  respect to  the
     Common Stock as so changed.  

                      11.      Rule 144 Reporting.  With a view to making avail-
     able the benefits  of certain rules and regulations of the Commission which
     may at  any time  permit the  sale of  the Restricted Stock  to the  public
     without registration,  at all  times after  90 days after any  registration
     statement covering a  public offering of  securities of  the Company  under
     the Securities Act shall have become effective, the Company agrees to:  

                      (a)      make  and keep  public information  available, as
     those terms are  understood and defined  in Rule 144  under the  Securities
     Act;  

                      (b)      use its best efforts  to file with the Commission
     in a timely manner all reports and other  documents required of the Company
     under the Securities Act and the Exchange Act; and  

                      (c)      furnish to each holder of Restricted Stock forth-
     with upon request a written statement by  the Company as to its  compliance
     with the  reporting requirements of such Rule 144 and of the Securities Act
     and the Exchange Act, a copy of the most recent annual  or quarterly report
     of  the Company,  and  such other  reports and  documents  so filed  by the
     Company  as such  holder may reasonably  request in availing  itself of any
     rule  or regulation  of  the Commission  allowing such  holder to  sell any
     Restricted Stock without registration.  

                      12.      Representations and  Warranties of  the  Company.
     The Company represents and warrants to you as follows:  

                      (a)   The  execution,  delivery  and performance  of  this
     Agreement  by  the Company  have  been  duly  authorized  by all  requisite
     corporate action and  will not violate any  provision of law, any  order of

     inure  to the  benefit  of the  respective  successors and  assigns of  the
     parties hereto (including without limitation transferees  of any Restricted
     Stock), whether so expressed or  not, provided, however, that  registration
     rights  conferred herein  on  the holders  of  Restricted Stock  shall only

     transferred  to such  transferee  at  least  20%  of the  total  shares  of
     Restricted  Stock originally issued pursuant  to the  Purchase Agreement to
     the  direct  or  indirect   transferor  of  such  transferee  or  (ii) such

              address of such party set forth in the Purchase Agreement;  

                      if to any  subsequent holder of Restricted Stock, to it at
              such address as may have  been furnished to the Company in writing
              by such holder;  

     or, in  any case,  at such other  address or addresses  as shall  have been

     Stock) or to the holders  of Restricted Stock (in the case  of the Company)
     in accordance with the provisions of this paragraph.

                      (e)      This  Agreement may  be executed  in two  or more
     counterparts, each of  which shall be deemed an  original, but all of which

                      (f)      The obligations of the Company to register shares
     of  Restricted  Stock under  Sections 4,  5 or  6  shall  terminate on  the

     pursuant to Rule 144(k) under the Securities Act.

                      (g)      Each holder of Restricted Stock who is a party to

              FOR VALUE RECEIVED, Virtual Open Network Environment Corporation,
     a Delaware corporation (the "Company"), hereby promises to pay to the
     order of JMI Equity Fund II, L.P., or registered assigns (hereinafter
     referred to as the "Payee"), on or before June 18, 2000, the principal sum
     of One Million, Five Hundred Thousand Dollars ($1,500,000.00) or such part
     thereof as then remains unpaid and to pay interest from the date hereof on
     the whole amount of said principal sum remaining from time to time unpaid
     at the rate of eight percent (8%) per annum, such interest shall be
     payable quarterly in arrears on the last day of March, June, September and
     December in each year, the first such payment to be due and payable on
     September 30, 1996, and at maturity or prior prepayment of the Notes in
     full; provided, however, that if an Event of Default (as defined in the
     Agreement (defined below) has occurred and is continuing, from and after
     the date such Event of Default occurred the entire outstanding unpaid
     principal balance of this Note and any matured but unpaid interest from
     time to time due thereon shall bear interest, payable on demand, at the
     rate twelve percent (12%) per annum, or such lower rate as then may be the

     and a 30-day month, counting actual days elapsed.

              This Note is issued pursuant to, and is entitled to the benefits
     of, (i) the Senior Subordinated Note and Warrant Purchase Agreement dated
     as of June 18, 1996 between the Company and the Payee (as the same may be
     amended from time to time, hereinafter referred to as the "Agreement"),
     and (ii) the Subordination Agreement dated as of June 18, 1996 among the
     Company, the Payee, James F. Chen and Hai Hua Cheng (as the same may be

     or delivered to the Payee at its address referred to in Section 9.03 of
     the Agreement, without any presentment or notation of payment, except that
     prior to any transfer of this Note, the holder hereof shall endorse on
     this Note a record of the date to which interest has been paid and all
     payments made on account of principal of this Note.  The Company shall
     have no duty to pro rate interest payments with respect to this Note and
     shall pay the entire amount of any interest payment on this Note solely to

     in Control; or (3) sale of all or substantially all of the assets of the
     Company, the Company shall prepay, without premium, this Note in whole,
     together with interest due hereon through the date of prepayment.  This
     Note may also be prepaid in whole or in part at any time without premium
     or penalty.

     Company to pay interest at a rate in excess of the maximum rate permitted

     computation of payment of interest due.

              The indebtedness evidenced by this Note and the rights and
     remedies of the Payee under the Agreement and the Operative Documents
     shall be subordinate and junior to certain indebtedness of the Company to
     the Bank.  This Note will be senior subordinated indebtedness of the
     Company ranking pari passu with all other existing and future senior

     registered in the name of, the transferee or transferees.  The Company may
     treat the person in whose name this Note is registered as the owner hereof
     for the purpose of receiving payment and for all other purposes.  

              In case any payment herein provided for shall not be paid when
     due, the Company promises to pay all cost of collection, including all

                            COMMON STOCK PURCHASE WARRANT

     Warrant No. W-1                            Number of Shares: 100,000


                    VIRTUAL OPEN NETWORK ENVIRONMENT CORPORATION


                               Void after June 18, 2006


              1.  Issuance.  This Warrant is issued to JMI Equity Fund II,
     L.P., a Delaware limited partnership, by Virtual Open Network Environment
     Corporation, a Delaware corporation (hereinafter with its successors
     called the "Company").
                 -------

              2.  Purchase Price; Number of Shares.  Subject to the terms and
     conditions hereinafter set forth, the registered holder of this Warrant
     (the "Holder"), commencing on the date hereof, is entitled upon surrender
     of this Warrant with the subscription form annexed hereto duly executed,
     at the principal office of the Company, or such other office as the
     Company shall notify the Holder of in writing, to purchase from the
     Company at a price (the "Purchase Price") of $.01 per share, 100,000 fully
     paid and nonassessable shares of Common Stock, par value $.001 per share,
     of the Company (the "Common Stock").  Until such time as this Warrant is
     exercised in full or expires, the Purchase Price and the securities
     issuable upon exercise of this Warrant are subject to adjustment as
     hereinafter provided.  

              3.  Payment of Purchase Price.  The Purchase Price may be paid
     (i) in cash or by check, (ii) by the surrender by the Holder to the
     Company of any promissory notes or other obligations issued by the
     Company, with all such notes and obligations so surrendered being credited
     against the Purchase Price in an amount equal to the principal amount
     thereof plus accrued interest to the date of surrender, (iii) through
     delivery by the Holder to the Company of other securities issued by the
     Company, with such securities being credited against the Purchase Price in
     an amount equal to the fair market value thereof, as determined in
     accordance with Section 4, or (iv) by any combination of the foregoing. 
     The Board shall promptly respond in writing to an inquiry by the Holder as
     to the fair market value of any securities the Holder may wish to deliver
     to the Company pursuant to clause (iii) above.

                                   Warrant--Page 2

              4.  Net Issue Election.  The Holder may elect to receive, without
     the payment by the Holder of any additional consideration, shares equal to
     the value of this Warrant or any portion hereof by the surrender of this
     Warrant or such portion to the Company, with the net issue election notice
     annexed hereto duly executed, at the office of the Company.  Thereupon,
     the Company shall issue to the Holder such number of fully paid and
     nonassessable shares of Common Stock as is computed using the following
     formula:

                                     X = Y (A-B)
                                          -------
                                           A 

     where 
              
              X  =    the number of shares to be issued to the Holder pursuant
                      to this Section 4.

              Y  =    the number of shares covered by this Warrant in respect
                      of which the net issue election is made pursuant to this
                      Section 4.

              A  =    the fair market value of one share of Common Stock, as
                      determined in accordance with this Section 4, as at the
                      time the net issue election is made pursuant to this
                      Section 4. 

              B  =    the Purchase Price in effect under this Warrant at the
                      time the net issue election is made pursuant to this
                      Section 4.

              The "fair market value" of a share of Common Stock shall be
     determined as follows: 

                      (a) If the Common Stock is publicly traded on a
     particular measurement date, the fair market value of a share of Common
     Stock on such measurement date shall be: (i) the average of the closing
     sale prices for the Common Stock, as quoted on any national securities
     exchange or the Nasdaq National Market on which such stock shall be listed
     or designated for trading, or (ii) if the Common Stock is not then traded
     on a national securities exchange or on the Nasdaq National Market, but is
     quoted on the National Association of Securities Dealers, Inc. s Automated
     Quotation System ("NASDAQ"), the average of the closing bid and asked
     prices for the Common Stock as reported on NASDAQ, in each case for the
     five trading days ending on the second trading day prior to the
     measurement date; provided, however, that if the Company shall declare a
     dividend or distribution (as discussed in Section 9) payable to holders of
     the Common Stock of record on any date during the period (inclusive)
     beginning with the first date of any period of trading days utilized to
     determine a fair market value and ending on the date immediately prior to
     the measurement date, then the calculation of fair market value shall be
     appropriately discounted to remove the effect of the value of such

<PAGE>







                                   Warrant--Page 3

     dividend or distribution from the calculation of the fair market value for
     dates prior to and including the record date.

                      (b)  If the Common Stock is not publicly traded on a
     particular measurement date, the fair market value of a share of Common
     Stock as of such measurement date shall be determined by the Board of
     Directors of the Company acting in good faith (taking into account any
     recent corporate events involving a determination of value for the
     Company's securities (e.g., the closing of an offering of securities or
     the granting of incentive stock options)).

              The Board shall promptly respond in writing to an inquiry by the
     Holder as to the fair market value of one share of Common Stock.

              5.  Partial Exercise.  This Warrant may be exercised in part, and
     the Holder shall be entitled to receive a new warrant, which shall be
     dated as of the date of this Warrant, covering the number of shares in
     respect of which this Warrant shall not have been exercised.  

              6.  Issuance Date.  The person or persons in whose name or names
     any certificate representing shares of Common Stock is issued hereunder
     shall be deemed to have become the holder of record of the shares
     represented thereby as at the close of business on the date this Warrant
     is exercised with respect to such shares, whether or not the transfer
     books of the Company shall be closed.  

              7.  Expiration Date; Automatic Exercise.  This Warrant shall
     expire at the close of business on June 18, 2006, and shall be void
     thereafter.  Notwithstanding the foregoing, this Warrant shall
     automatically be deemed to be exercised in full pursuant to the provisions
     of Section 4, without any further action on behalf of the Holder, upon the
     earliest of (i) June 30, 1996, (ii) immediately prior to the closing of
     the Company s initial public offering of shares of Common Stock or (iii)
     immediately prior to the time this Warrant would otherwise expire pursuant
     to the preceding sentence.

              8.  Reserved Shares; Valid Issuance.  The Company covenants that
     it will at all times from and after the date hereof reserve and keep
     available such number of its authorized shares of Common Stock, free from
     all preemptive or similar rights therein, as will be sufficient to permit
     the exercise of this Warrant in full.  The Company further covenants that
     such shares as may be issued pursuant to the exercise of this Warrant
     will, upon issuance, be duly and validly issued, fully paid and
     nonassessable and free from all taxes, liens and charges with respect to
     the issuance thereof.  

              9.  Dividends.  If the Company shall subdivide the Common Stock,
     by split-up or otherwise, or combine the Common Stock, or issue additional
     shares of Common Stock in payment of a stock dividend on the Common Stock,
     the number of shares issuable on the exercise of this Warrant shall
     forthwith be proportionately increased in the case of a subdivision or
     stock dividend, or proportionately decreased in the case of a combination,

<PAGE>







                                   Warrant--Page 4

     and the Purchase Price shall forthwith be proportionately decreased in the
     case of a subdivision or stock dividend, or proportionately increased in
     the case of a combination.  The Company shall not pay any dividend or make
     any other distribution upon the Common Stock payable in cash, property or
     securities of the Company other than Common Stock or in securities of a
     corporation other than the Company.

              10.  Mergers and Reclassifications.  If there shall be any
     reclassification, capital reorganization or change of the Common Stock
     (other than as a result of a subdivision, combination or stock dividend
     provided for in Section 9), or any consolidation of the Company with, or
     merger of the Company into, another corporation or other business
     organization (other than a consolidation or merger in which the Company is
     the continuing corporation and which does not result in any
     reclassification or change of the outstanding Common Stock), or any sale
     or conveyance to another corporation or other business organization of all
     or substantially all of the assets of the Company, then, as a condition of
     such reclassification, reorganization, change, consolidation, merger, sale
     or conveyance, lawful provisions shall be made, and duly executed
     documents evidencing the same from the Company or its successor shall be
     delivered to the Holder, so that the Holder shall thereafter have the
     right to receive, at a total price not to exceed that payable upon the
     exercise of this Warrant in full, the kind and amount of shares of stock
     and other securities and property receivable upon such reclassification,
     reorganization, change, consolidation, merger, sale or conveyance by a
     holder of the number of shares of Common Stock which might have been
     received by the Holder immediately prior to such reclassification,
     reorganization, change, consolidation, merger, sale or conveyance if the
     Holder had exercised this Warrant in full prior thereto, and in any such
     case appropriate provisions shall be made with respect to the rights and
     interest of the Holder to the end that the provisions hereof (including
     without limitation, provisions for the adjustment of the Purchase Price
     and the number of shares issuable hereunder) shall thereafter be
     applicable in relation to any shares of stock or other securities and
     property thereafter deliverable upon exercise hereof.

              11.  Adjustments for Issuances Below Purchase Price.  In case the
     Company shall at any time or from time to time issue or sell any shares of
     Common Stock (other than (i) shares issued in transactions to which
     Sections 9 or 10 of this Warrant apply, (ii) shares issuable pursuant to
     obligations existing on the date hereof and (iii) up to 4,028,444 shares
     of Common Stock (appropriately adjusted for subdivisions, combinations,
     stock dividends and the like) issued to employees, officers, directors or
     consultants of the Company in connection with their service to the
     Company, plus such number of shares of Common Stock (as so adjusted) which
     are repurchased by the Company from such persons pursuant to contractual
     rights held by the Company and at repurchase prices not exceeding the
     respective original purchase prices paid by such persons to the Company
     therefor) for a consideration per share less than the Purchase Price in
     effect for this Warrant immediately prior to the time of such issue or
     sale, then forthwith upon such issue or sale, the Purchase Price shall
     (until another such issue or sale) be reduced to the price at which the

<PAGE>







                                   Warrant--Page 5

     Company issued or sold such shares of Common Stock.  Further, the number
     of shares purchasable hereunder shall be increased to a number determined
     by dividing (i) the number of shares purchasable hereunder immediately
     prior to such issue or sale, multiplied by the Purchase Price hereunder
     immediately prior to such event, by (ii) the Purchase Price in effect
     immediately after the foregoing adjustment.  

              For the purpose of this Section 11, the following provisions
     shall also be applicable:  

                      A.  In case the Company shall in any manner grant
              (whether directly or by assumption in a merger or otherwise) any
              warrants or other rights to subscribe for or to purchase, or any
              options for the purchase of, Common Stock or any stock or
              security convertible into or exchangeable for Common Stock (such
              warrants, rights or options being called "Options" and such
              convertible or exchangeable stock or securities being called
              "Convertible Securities"), at a price less than the Purchase
              Price in effect immediately prior to the time of the offering of
              such Options, all shares of Common Stock which the holders of
              such Options shall be entitled to subscribe for or purchase
              pursuant to such Options shall be deemed to be issued or sold as
              of the date of the granting of such Options, as the case may be,
              and the minimum aggregate consideration named in such Options for
              the Common Stock or Convertible Securities covered thereby, plus
              the consideration received by the Company for such Options, shall
              be deemed to be the consideration actually received by the
              Company (as of the date of the granting of such Options, as the
              case may be) for the issue or sale of such shares.

                      B.  In case the Company shall in any manner issue or sell
              any Convertible Securities and the price per share for which
              Common Stock is deliverable upon such conversion or exchange
              (determined by dividing (i) the total minimum amount received or
              receivable by the Company in consideration of the issue or sale
              of such Convertible Securities, plus the total minimum amount of
              premiums, if any, payable to the Company upon conversion or
              exchange, by (ii) the total number of shares of Common Stock
              necessary to effect the conversion or exchange of all such
              Convertible Securities) shall be less than the Purchase Price in
              effect immediately prior to the time of such issue or sale, then
              such issue or sale shall be deemed to be an issue or sale (as of
              the date of issue or sale of such convertible or exchangeable
              shares or obligations) of the total maximum number of shares of
              Common Stock necessary to effect the conversion or exchange of
              all such Convertible Securities, and the total minimum amount
              received or receivable by the Company in consideration of the
              issue or sale of such Convertible Securities, plus the total
              minimum amount of premiums, if any, payable to the Company upon
              exchange or conversion, shall be deemed to be the consideration
              actually received (as of the date of the issue or sale of such


<PAGE>






                                   Warrant--Page 6

              convertible or exchangeable shares or obligations) for the issue
              or sale of such Common Stock.  

                      C.  If there shall be any change in (i) the minimum
              aggregate consideration named in the Options, (ii) the
              consideration received by the Company for such Options, (iii) the
              price per share for which Common Stock is deliverable upon the
              conversion or exchange of the Convertible Securities, (iv) the
              number of shares which may be subscribed for or purchased
              pursuant to the Options, or (v) the rate at which the Convertible
              Securities are convertible into or exchangeable for Common Stock,
              then the Purchase Price in effect at the time of such event shall
              be readjusted to the Purchase Price which would have been in
              effect at such time had such rights, options, or convertible or
              exchangeable shares or obligations provided for such changed
              consideration, price per share, number of shares, or rate of
              conversion or exchange, as the case may be, at the time initially
              offered, granted, issued or sold, but only if as a result of such
              adjustment the Purchase Price then in effect hereunder is not
              increased above $3.00 per share (appropriately adjusted to
              reflect the occurrence of any event described in Section 9
              hereto).

                      D.  In case the Company shall declare a dividend or make
              any other distribution upon any stock of the Company payable in
              Common Stock (except for dividends or distributions upon the
              Common Stock), Options or Convertible Securities, any Common
              Stock, Options or Convertible Securities, as the case may be,
              issuable in payment of such dividend or distribution shall be
              deemed to have been issued or sold at a price per share equal to
              $.001.  

                      E.  In determining the amount of consideration received
              by the Company for Common Stock, Options or Convertible
              Securities, no deduction shall be made for expenses or
              underwriting discounts or commissions paid by the Company.  The
              Board shall determine in good faith the fair value of the amount
              of consideration other than money received by the Company upon
              the issue by it of any of its securities.  The Board shall, in
              case any Common Stock, Options or Convertible Securities are
              issued with other stock, securities or assets of the Company,
              determine in good faith what part of the consideration received
              therefor is applicable to the issue of the Common Stock, Options
              or Convertible Securities.  

                      F.  In case the Company shall take a record of the
              holders of its Common Stock for the purpose of entitling them (i)
              to receive a dividend or other distribution payable in Common
              Stock, Options or Convertible Securities or (ii) to subscribe for
              or purchase Common Stock, Options or Convertible Securities, then
              such record date shall be deemed to be the date of the issue or
              sale of the shares of Common Stock deemed to have been issued or

<PAGE>







                                   Warrant--Page 7

              sold upon the declaration of such dividend or the making of such
              other distribution or the date of the granting of such right of
              subscription or purchase, as the case may be.  

                      G.  The disposition of any shares of Common Stock owned
              or held by or for the account of the Company shall be considered
              an issue or sale of Common Stock for the purpose of this
              Section 11.  

              12.  Fractional Shares.  In no event shall any fractional share
     of Common Stock be issued upon any exercise of this Warrant.  If, upon
     exercise of this Warrant as an entirety, the Holder would, except as
     provided in this Section 12, be entitled to receive a fractional share of
     Common Stock, then the Company shall issue the next higher number of full
     shares of Common Stock, issuing a full share with respect to such
     fractional share.

              13.  Certificate of Adjustment.  Whenever the Purchase Price is
     adjusted, as herein provided, the Company shall promptly deliver to the
     Holder a certificate of a firm of independent public accountants setting
     forth the Purchase Price after such adjustment and setting forth a brief
     statement of the facts requiring such adjustment.  

              14.  Notices of Record Date, Etc.  In the event of:

                               (a)  any taking by the Company of a record of the
              holders of any class of securities for the purpose of determining
              the holders thereof who are entitled to receive any dividend or
              other distribution, or any right to subscribe for, purchase or
              otherwise acquire any shares of stock of any class or any other
              securities or property, or to receive any other right,

                               (b)  any reclassification of the capital stock of
              the Company, capital reorganization of the Company, consolidation
              or merger involving the Company, or sale or conveyance of all or
              substantially all of its assets, or 

                               (c)  any voluntary or involuntary dissolution,
              liquidation or winding-up of the Company,

     then and in each such event the Company will mail or cause to be mailed to
     the Holder a notice specifying (i) the date on which any such record is to
     be taken for the purpose of such dividend, distribution or right, and
     stating the amount and character of such dividend, distribution or right,
     or (ii) the date on which any such reclassification, reorganization,
     consolidation, merger, sale or conveyance, dissolution, liquidation or
     winding-up is to take place, and the time, if any is to be fixed, as of
     which the holders of record in respect of such event are to be determined. 
     Such notice shall be mailed at least 20 days prior to the date specified
     in such notice on which any such action is to be taken.

              15.  Amendment.  The terms of this Warrant may be amended,
     modified or waived only with the written consent of the Company and the
     Holder.

              16.  Warrant Register; Transfers, Etc.  
                   ---------------------------------

                      A.  The Company will maintain a register containing the
              name and address of the Holder.  The Holder may change its
              address as shown on the warrant register by written notice to the
              Company requesting such change.  Any notice or written
              communication required or permitted to be given to the Holder may
              be given by certified mail or delivered to the Holder at its
              address as shown on the warrant register.

                      B.  If this Warrant or the shares of Common Stock issued
              or issuable upon exercise of this Warrant shall have been
              registered under the Securities Act and applicable state
              securities laws, or if such registration is not required, as
              demonstrated by opinion of counsel satisfactory to the Company,
              this Warrant may be transferred by the Holder with respect to any
              or all of the shares purchasable hereunder.  Upon surrender of
              this Warrant to the Company, together with the assignment hereof
              properly endorsed, for transfer of this Warrant as an entirety by
              the Holder, the Company shall issue a new warrant of the same
              denomination to the assignee.  Upon surrender of this Warrant to
              the Company, together with the assignment hereof properly
              endorsed, by the Holder for transfer with respect to a portion of
              the shares of Common Stock purchasable hereunder, the Company
              shall issue a new warrant to the assignee, in such denomination
              as shall be requested by the Holder hereof, and shall issue to
              such Holder a new warrant covering the number of shares in
              respect of which this Warrant shall not have been transferred.

                      C.  In case this Warrant shall be mutilated, lost, stolen
              or destroyed, the Company shall issue a new warrant of like tenor
              and denomination and deliver the same (i) in exchange and
              substitution for and upon surrender and cancellation of any
              mutilated Warrant, or (ii) in lieu of any Warrant lost, stolen or
              destroyed, upon receipt of evidence reasonably satisfactory to
              the Company of the loss, theft or destruction of such Warrant
              (including a reasonably detailed affidavit with respect to the
              circumstances of any loss, theft or destruction) and of indemnity
              reasonably satisfactory to the Company, provided, however, that
              so long as JMI Equity Fund, L.P. is the registered holder of this
              Warrant, no indemnity shall be required other than its written
              agreement to indemnify the Company against any loss arising from
              the issuance of such new warrant.

              17.  No Impairment.  The Company will not, by amendment of its
     Amended and Restated Certificate of Incorporation or through any
     reclassification, capital reorganization, consolidation, merger, sale or

<PAGE>







                                   Warrant--Page 9

     conveyance of assets, dissolution, liquidation, issue or sale of
     securities or any other voluntary action, avoid or seek to avoid the
     observance or performance of any of the terms of this Warrant, but will at
     all times in good faith assist in the carrying out of all such terms and
     in the taking of all such action as may be necessary or appropriate in
     order to protect the rights of the Holder.

              18.  Governing Law.   The provisions and terms of this Warrant
     shall be governed by and construed in accordance with the internal laws of
     the State of Delaware.

              19.  Successors and Assigns.  This Warrant shall be binding upon
     the Company's successors and assigns and shall inure to the benefit of the
     Holder's successors, legal representatives and permitted assigns.

              20.  Business Days.  If the last or appointed day for the taking
     of any action required or the expiration of any right granted herein shall
     be a Saturday or Sunday or a legal holiday in Delaware, then such action
     may be taken or right may be exercised on the next succeeding day which is
     not a Saturday or Sunday or such a legal holiday.

     UNLESS  SUCH  SALE OR  TRANSFER  IS  IN  ACCORDANCE  WITH THE  REGISTRATION

                            COMMON STOCK PURCHASE WARRANT

     Warrant No. W-2                            Number of Shares: 400,000


                    VIRTUAL OPEN NETWORK ENVIRONMENT CORPORATION


                               Void after June 18, 2006


     1.  Issuance.  This Warrant is issued to JMI Equity Fund II, L.P., a
     Delaware limited partnership, by Virtual Open Network Environment
     Corporation, a Delaware corporation (hereinafter with its successors
     called the "Company").
                   -------

              2.  Purchase Price; Number of Shares.  Subject to the terms and
     conditions hereinafter set forth, the registered holder of this Warrant
     (the "Holder"), commencing on the date hereof, is entitled upon surrender
     of this Warrant with the subscription form annexed hereto duly executed,
     at the principal office of the Company, or such other office as the
     Company shall notify the Holder of in writing, to purchase from the
     Company at a price (the "Purchase Price") of $3.00 per share, 400,000
     fully paid and nonassessable shares of Common Stock, par value $.001 per
     share, of the Company (the "Common Stock").  Until such time as this
     Warrant is exercised in full or expires, the Purchase Price and the
     securities issuable upon exercise of this Warrant are subject to
     adjustment as hereinafter provided.  

              3.  Payment of Purchase Price.  The Purchase Price may be paid
     (i) in cash or by check, (ii) by the surrender by the Holder to the
     Company of any promissory notes or other obligations issued by the
     Company, with all such notes and obligations so surrendered being credited
     against the Purchase Price in an amount equal to the principal amount
     thereof plus accrued interest to the date of surrender, (iii) through
     delivery by the Holder to the Company of other securities issued by the
     Company, with such securities being credited against the Purchase Price in
     an amount equal to the fair market value thereof, as determined in
     accordance with Section 4, or (iv) by any combination of the foregoing. 
     The Board shall promptly respond in writing to an inquiry by the Holder as
     to the fair market value of any securities the Holder may wish to deliver
     to the Company pursuant to clause (iii) above.

                                  Warrant - Page 2 

              4.  Net Issue Election.  The Holder may elect to receive, without
     the payment by the Holder of any additional consideration, shares equal to
     the value of this Warrant or any portion hereof by the surrender of this
     Warrant or such portion to the Company, with the net issue election notice
     annexed hereto duly executed, at the office of the Company.  Thereupon,
     the Company shall issue to the Holder such number of fully paid and
     nonassessable shares of Common Stock as is computed using the following
     formula:

                                     X = Y (A-B)
                                         -------
                                           A 

     where 

                      X  =     the number of shares to be issued to the Holder
                               pursuant to this Section 4.

                      Y  =     the number of shares covered by this Warrant in
                               respect of which the net issue election is made
                               pursuant to this Section 4.

                      A  =     the fair market value of one share of Common
                               Stock, as determined in accordance with this
                               Section 4, as at the time the net issue election
                               is made pursuant to this Section 4. 

                      B  =     the Purchase Price in effect under this Warrant
                               at the time the net issue election is made
                               pursuant to this Section 4.

              The "fair market value" of a share of Common Stock shall be
     determined as follows: 

                      (a) If the Common Stock is publicly traded on a
     particular measurement date, the fair market value of a share of Common
     Stock on such measurement date shall be: (i) the average of the closing
     sale prices for the Common Stock, as quoted on any national securities
     exchange or the Nasdaq National Market on which such stock shall be listed
     or designated for trading, or (ii) if the Common Stock is not then traded
     on a national securities exchange or on the Nasdaq National Market, but is
     quoted on the National Association of Securities Dealers, Inc.'s Automated
     Quotation System ("NASDAQ"), the average of the closing bid and asked
     prices for the Common Stock as reported on NASDAQ, in each case for the
     five trading days ending on the second trading day prior to the
     measurement date; provided, however, that if the Company shall declare a
     dividend or distribution (as discussed in Section 9) payable to holders of
     the Common Stock of record on any date during the period (inclusive)
     beginning with the first date of any period of trading days utilized to
     determine a fair market value and ending on the date immediately prior to
     the measurement date, then the calculation of fair market value shall be
     appropriately discounted to remove the effect of the value of such

<PAGE>







                                  Warrant - Page 3 

     dividend or distribution from the calculation of the fair market value for
     dates prior to and including the record date.

                      (b)  If the Common Stock is not publicly traded on a
     particular measurement date, the fair market value of a share of Common
     Stock as of such measurement date shall be determined by the Board of
     Directors of the Company acting in good faith (taking into account any
     recent corporate events involving a determination of value for the
     Company's securities (e.g., the closing of an offering of securities or
     the granting of incentive stock options)).

              The Board shall promptly respond in writing to an inquiry by the
     Holder as to the fair market value of one share of Common Stock.

              5.  Partial Exercise.  This Warrant may be exercised in part, and
     the Holder shall be entitled to receive a new warrant, which shall be
     dated as of the date of this Warrant, covering the number of shares in
     respect of which this Warrant shall not have been exercised.  

              6.  Issuance Date.  The person or persons in whose name or names
     any certificate representing shares of Common Stock is issued hereunder
     shall be deemed to have become the holder of record of the shares
     represented thereby as at the close of business on the date this Warrant
     is exercised with respect to such shares, whether or not the transfer
     books of the Company shall be closed.  

              7.  Expiration Date; Automatic Exercise.  This Warrant shall
     expire at the close of business on June 18, 2006, and shall be void
     thereafter.  Notwithstanding the foregoing, this Warrant shall
     automatically be deemed to be exercised in full pursuant to the provisions
     of Section 4, without any further action on behalf of the Holder,
     immediately prior to the time this Warrant would otherwise expire pursuant
     to the preceding sentence.

              8.  Reserved Shares; Valid Issuance.  The Company covenants that
     it will at all times from and after the date hereof reserve and keep
     available such number of its authorized shares of Common Stock, free from
     all preemptive or similar rights therein, as will be sufficient to permit
     the exercise of this Warrant in full.  The Company further covenants that
     such shares as may be issued pursuant to the exercise of this Warrant
     will, upon issuance, be duly and validly issued, fully paid and
     nonassessable and free from all taxes, liens and charges with respect to
     the issuance thereof.  

              9.  Dividends.  If the Company shall subdivide the Common Stock,
     by split-up or otherwise, or combine the Common Stock, or issue additional
     shares of Common Stock in payment of a stock dividend on the Common Stock,
     the number of shares issuable on the exercise of this Warrant shall
     forthwith be proportionately increased in the case of a subdivision or
     stock dividend, or proportionately decreased in the case of a combination,
     and the Purchase Price shall forthwith be proportionately decreased in the
     case of a subdivision or stock dividend, or proportionately increased in

<PAGE>







                                  Warrant - Page 4 

     the case of a combination.  The Company shall not pay any dividend or make
     any other distribution upon the Common Stock payable in cash, property or
     securities of the Company other than Common Stock or in securities of a
     corporation other than the Company.

              10.  Mergers and Reclassifications.  If there shall be any
     reclassification, capital reorganization or change of the Common Stock
     (other than as a result of a subdivision, combination or stock dividend
     provided for in Section 9), or any consolidation of the Company with, or
     merger of the Company into, another corporation or other business
     organization (other than a consolidation or merger in which the Company is
     the continuing corporation and which does not result in any
     reclassification or change of the outstanding Common Stock), or any sale
     or conveyance to another corporation or other business organization of all
     or substantially all of the assets of the Company, then, as a condition of
     such reclassification, reorganization, change, consolidation, merger, sale
     or conveyance, lawful provisions shall be made, and duly executed
     documents evidencing the same from the Company or its successor shall be
     delivered to the Holder, so that the Holder shall thereafter have the
     right to receive, at a total price not to exceed that payable upon the
     exercise of this Warrant in full, the kind and amount of shares of stock
     and other securities and property receivable upon such reclassification,
     reorganization, change, consolidation, merger, sale or conveyance by a
     holder of the number of shares of Common Stock which might have been
     received by the Holder immediately prior to such reclassification,
     reorganization, change, consolidation, merger, sale or conveyance if the
     Holder had exercised this Warrant in full prior thereto, and in any such
     case appropriate provisions shall be made with respect to the rights and
     interest of the Holder to the end that the provisions hereof (including
     without limitation, provisions for the adjustment of the Purchase Price
     and the number of shares issuable hereunder) shall thereafter be
     applicable in relation to any shares of stock or other securities and
     property thereafter deliverable upon exercise hereof.

              11.  Adjustments for Issuances Below Purchase Price.  In case the
     Company shall at any time or from time to time issue or sell any shares of
     Common Stock (other than (i) shares issued in transactions to which
     Sections 9 or 10 of this Warrant apply, (ii) shares issuable pursuant to
     obligations existing on the date hereof and (iii) up to 4,028,444 shares
     of Common Stock (appropriately adjusted for subdivisions, combinations,
     stock dividends and the like) issued to employees, officers, directors or
     consultants of the Company in connection with their service to the
     Company, plus such number of shares of Common Stock (as so adjusted) which
     are repurchased by the Company from such persons pursuant to contractual
     rights held by the Company and at repurchase prices not exceeding the
     respective original purchase prices paid by such persons to the Company
     therefor) for a consideration per share less than the Purchase Price in
     effect for this Warrant immediately prior to the time of such issue or
     sale, then forthwith upon such issue or sale, the Purchase Price shall
     (until another such issue or sale) be reduced to the price at which the
     Company issued or sold such shares of Common Stock.  Further, the number
     of shares purchasable hereunder shall be increased to a number determined

<PAGE>







                                  Warrant - Page 5 

     by dividing (i) the number of shares purchasable hereunder immediately
     prior to such issue or sale, multiplied by the Purchase Price hereunder
     immediately prior to such event, by (ii) the Purchase Price in effect
     immediately after the foregoing adjustment.  

              For the purpose of this Section 11, the following provisions
     shall also be applicable:  

                      A.  In case the Company shall in any manner grant
              (whether directly or by assumption in a merger or otherwise) any
              warrants or other rights to subscribe for or to purchase, or any
              options for the purchase of, Common Stock or any stock or
              security convertible into or exchangeable for Common Stock (such
              warrants, rights or options being called "Options" and such
              convertible or exchangeable stock or securities being called
              "Convertible Securities"), at a price less than the Purchase
              Price in effect immediately prior to the time of the offering of
              such Options, all shares of Common Stock which the holders of
              such Options shall be entitled to subscribe for or purchase
              pursuant to such Options shall be deemed to be issued or sold as
              of the date of the granting of such Options, as the case may be,
              and the minimum aggregate consideration named in such Options for
              the Common Stock or Convertible Securities covered thereby, plus
              the consideration received by the Company for such Options, shall
              be deemed to be the consideration actually received by the
              Company (as of the date of the granting of such Options, as the
              case may be) for the issue or sale of such shares.

                      B.  In case the Company shall in any manner issue or sell
              any Convertible Securities and the price per share for which
              Common Stock is deliverable upon such conversion or exchange
              (determined by dividing (i) the total minimum amount received or
              receivable by the Company in consideration of the issue or sale
              of such Convertible Securities, plus the total minimum amount of 
              premiums, if any, payable to the Company upon conversion or
              exchange, by (ii) the total number of shares of Common Stock
              necessary to effect the conversion or exchange of all such
              Convertible Securities) shall be less than the Purchase Price in
              effect immediately prior to the time of such issue or sale, then
              such issue or sale shall be deemed to be an issue or sale (as of
              the date of issue or sale of such convertible or exchangeable
              shares or obligations) of the total maximum number of shares of
              Common Stock necessary to effect the conversion or exchange of
              all such Convertible Securities, and the total minimum amount
              received or receivable by the Company in consideration of the
              issue or sale of such Convertible Securities, plus the total
              minimum amount of premiums, if any, payable to the Company upon
              exchange or conversion, shall be deemed to be the consideration
              actually received (as of the date of the issue or sale of such
              convertible or exchangeable shares or obligations) for the issue 
              or sale of such Common Stock.

                      C.  If there shall be any change in (i) the minimum
              aggregate consideration named in the Options, (ii) the
              consideration received by the Company for such Options, (iii) the
              price per share for which Common Stock is deliverable upon the
              conversion or exchange of the Convertible Securities, (iv) the
              number of shares which may be subscribed for or purchased
              pursuant to the Options, or (v) the rate at which the Convertible
              Securities are convertible into or exchangeable for Common Stock,
              then the Purchase Price in effect at the time of such event shall
              be readjusted to the Purchase Price which would have been in
              effect at such time had such rights, options, or convertible or
              exchangeable shares or obligations provided for such changed
              consideration, price per share, number of shares, or rate of
              conversion or exchange, as the case may be, at the time initially
              offered, granted, issued or sold, but only if as a result of such
              adjustment the Purchase Price then in effect hereunder is not
              increased above $3.00 per share (appropriately adjusted to
              reflect the occurrence of any event described in Section 9
              hereto).

                      D.  In case the Company shall declare a dividend or make
              any other distribution upon any stock of the Company payable in
              Common Stock (except for dividends or distributions upon the
              Common Stock), Options or Convertible Securities, any Common
              Stock, Options or Convertible Securities, as the case may be,
              issuable in payment of such dividend or distribution shall be
              deemed to have been issued or sold at a price per share equal to
              $.001.  

                      E.  In determining the amount of consideration received
              by the Company for Common Stock, Options or Convertible
              Securities, no deduction shall be made for expenses or
              underwriting discounts or commissions paid by the Company.  The
              Board shall determine in good faith the fair value of the amount
              of consideration other than money received by the Company upon
              the issue by it of any of its securities.  The Board shall, in
              case any Common Stock, Options or Convertible Securities are
              issued with other stock, securities or assets of the Company,
              determine in good faith what part of the consideration received
              therefor is applicable to the issue of the Common Stock, Options
              or Convertible Securities.  

                      F.  In case the Company shall take a record of the
              holders of its Common Stock for the purpose of entitling them (i)
              to receive a dividend or other distribution payable in Common
              Stock, Options or Convertible Securities or (ii) to subscribe for
              or purchase Common Stock, Options or Convertible Securities, then
              such record date shall be deemed to be the date of the issue or
              sale of the shares of Common Stock deemed to have been issued or
              sold upon the declaration of such dividend or the making of such
              other distribution or the date of the granting of such right of
              subscription or purchase, as the case may be.

                                  Warrant - Page 7 

                      G.  The disposition of any shares of Common Stock owned
              or held by or for the account of the Company shall be considered
              an issue or sale of Common Stock for the purpose of this
              Section 11.  

              12.  Fractional Shares.  In no event shall any fractional share
     of Common Stock be issued upon any exercise of this Warrant.  If, upon
     exercise of this Warrant as an entirety, the Holder would, except as
     provided in this Section 12, be entitled to receive a fractional share of
     Common Stock, then the Company shall issue the next higher number of full
     shares of Common Stock, issuing a full share with respect to such
     fractional share.

              13.  Certificate of Adjustment.  Whenever the Purchase Price is
     adjusted, as herein provided, the Company shall promptly deliver to the
     Holder a certificate of a firm of independent public accountants setting
     forth the Purchase Price after such adjustment and setting forth a brief
     statement of the facts requiring such adjustment.  

              14.  Notices of Record Date, Etc.  In the event of:
                   ---------------------------

                      (a)  any taking by the Company of a record of the holders
              of any class of securities for the purpose of determining the
              holders thereof who are entitled to receive any dividend or other
              distribution, or any right to subscribe for, purchase or
              otherwise acquire any shares of stock of any class or any other
              securities or property, or to receive any other right,

                      (b)  any reclassification of the capital stock of the
              Company, capital reorganization of the Company, consolidation or
              merger involving the Company, or sale or conveyance of all or
              substantially all of its assets, or 

                      (c)  any voluntary or involuntary dissolution,
              liquidation or winding-up of the Company,

     then and in each such event the Company will mail or cause to be mailed to
     the Holder a notice specifying (i) the date on which any such record is to
     be taken for the purpose of such dividend, distribution or right, and
     stating the amount and character of such dividend, distribution or right,
     or (ii) the date on which any such reclassification, reorganization,
     consolidation, merger, sale or conveyance, dissolution, liquidation or
     winding-up is to take place, and the time, if any is to be fixed, as of
     which the holders of record in respect of such event are to be determined. 
     Such notice shall be mailed at least 20 days prior to the date specified
     in such notice on which any such action is to be taken.

              15.  Amendment.  The terms of this Warrant may be amended,
     modified or waived only with the written consent of the Company and the
     Holder.

              16.  Warrant Register; Transfers, Etc.
                   ---------------------------------

                      A.  The Company will maintain a register containing the
              name and address of the Holder.  The Holder may change its
              address as shown on the warrant register by written notice to the
              Company requesting such change.  Any notice or written
              communication required or permitted to be given to the Holder may
              be given by certified mail or delivered to the Holder at its
              address as shown on the warrant register.

                      B.  If this Warrant or the shares of Common Stock issued
              or issuable upon exercise of this Warrant shall have been
              registered under the Securities Act and applicable state
              securities laws, or if such registration is not required, as
              demonstrated by opinion of counsel satisfactorily to the Company,
              this Warrant may be transferred by the Holder with respect to any
              or all of the shares purchasable hereunder.  Upon surrender of
              this Warrant to the Company, together with the assignment hereof 
              properly endorsed, for transfer of this Warrant as an entirety by
              the Holder, the Company shall issue a new warrant of the same
              denomination to the assignee.  Upon surrender of this Warrant to
              the Company, together with the assignment hereof properly
              endorsed, by the Holder for transfer with respect to a portion of
              the shares of Common Stock purchasable hereunder, the Company
              shall issue a new warrant to the assignee, in such denomination
              as shall be requested by the Holder hereof, and shall issue to
              such Holder a new warrant covering the number of shares in
              respect of which this Warrant shall not have been transferred.

                      C.  In case this Warrant shall be mutilated, lost, stolen
              or destroyed, the Company shall issue a new warrant of like tenor
              and denomination and deliver the same (i) in exchange and
              substitution for and upon surrender and cancellation of any
              mutilated Warrant, or (ii) in lieu of any Warrant lost, stolen or
              destroyed, upon receipt of evidence reasonably satisfactory to
              the Company of the loss, theft or destruction of such Warrant
              (including a reasonably detailed affidavit with respect to the
              circumstances of any loss, theft or destruction) and of indemnity
              reasonably satisfactory to the Company, provided, however, that
              so long as JMI Equity Fund, L.P. is the registered holder of this
              Warrant, no indemnity shall be required other than its written
              agreement to indemnify the Company against any loss arising from
              the issuance of such new warrant.

              17.  No Impairment.  The Company will not, by amendment of its
     Amended and Restated Certificate of Incorporation or through any
     reclassification, capital reorganization, consolidation, merger, sale or
     conveyance of assets, dissolution, liquidation, issue or sale of
     securities or any other voluntary action, avoid or seek to avoid the
     observance or performance of any of the terms of this Warrant, but will at
     all times in good faith assist in the carrying out of all such terms and

     in the taking of all such action as may be necessary or appropriate in
     order to protect the rights of the Holder.

              18.  Governing Law.   The provisions and terms of this Warrant
     shall be governed by and construed in accordance with the internal laws of
     the State of Delaware.

              19.  Successors and Assigns.  This Warrant shall be binding upon
     the Company's successors and assigns and shall inure to the benefit of the
     Holder's successors, legal representatives and permitted assigns.

              20.  Business Days.  If the last or appointed day for the taking
     of any action required or the expiration of any right granted herein shall
     be a Saturday or Sunday or a legal holiday in Delaware, then such action
     may be taken or right may be exercised on the next succeeding day which is
