     3.2  DELIVERY AND INSTALLATION.

          (a)  On the Delivery Date, IONA will deliver to BroadVision's
designated facility one electronic copy of the Product and one electronic copy
of the Documentation.  The parties shall mutually determine who will install the

installation of the Product, BroadVision will reimburse IONA's reasonable travel
and lodging expenses in connection with the Product installation.

BroadVision will ensure that the designated computer is operational on the
Delivery Date, and will make available reasonable amounts of machine time and
other resources (such as access and passwords) reasonably necessary for IONA's
installation.  In the event IONA is responsible for installation of the Product,
if IONA is delayed from performing its obligations under this Section 3.2 solely
due to BroadVision's failure to make available the machine time and resources
reasonably necessary for IONA's installation, BroadVision will pay all of IONA's
costs attributable to such delay at IONA's then current time and materials
consulting rates.

     3.3  BROADVISION'S ACCEPTANCE.

shall determine to its satisfaction that the Products materially conform to the
Documentation.

          (b)  CORRECTION OF ERRORS.  If within such thirty (30) day period,
BroadVision determines that the functions of the Products do not materially
conform to the Documentation,  BroadVision shall notify IONA in writing
specifying the nonconforming Product and which part of the Documentation the
Product fails to conform to.  IONA shall correct any confirmed nonconformities
and shall provide the corrected Product to BroadVision as soon as commercially
reasonable.  BroadVision shall determine within seven (7) business days whether
the corrected Product conforms to the Documentation, and shall notify IONA
within such period of any continuing nonconformities.  If IONA is unable to
correct any material nonconformity, BroadVision may, at its discretion, refuse
to accept the nonconforming Product, in which case IONA shall refund the portion
of the fees BroadVision paid for such Product.

          (c)  BroadVision's failure to notify IONA of such non-conformance will
mean that BroadVision will be deemed to have accepted the Product.  BroadVision
will also be deemed to have accepted the Product if BroadVision uses the Product
commercially or resells the Product.

     3.4  DOCUMENTATION.  BroadVision may use only the applicable portions of
the Documentation, modified in its discretion, to create BroadVision's
documentation for the Final Products.  Before disseminating to third parties,
BroadVision will provide a copy of BroadVision's documentation to IONA for
IONA's review and approval, which shall be given within ten (10) business days
of submission and shall not be unreasonably withheld.  To the extent that
BroadVision uses the Documentation or portions thereof to create a derivative
work, BroadVision shall own all right, title and interest in and to the
derivative work.  BroadVision shall affix the following notice to any media
incorporating the Documentation:  COPYRIGHT

agreement.  The terms shall provide that IONA will [ * ]. Other terms [ * ]

negotiate in good faith for a period of thirty (30) days the terms of a [ * ]
agreement, which terms shall be reasonable and customary for the industry.

the Products for platforms other than Solaris and Windows NT, BroadVision and
IONA agree to negotiate for a period of thirty (30) days the terms of an
agreement covering IONA's development of such a version.  However, IONA may
decide not to do such development work in its sole discretion.

custom development services, the parties shall execute a mutually acceptable
written agreement which will be attached as an Exhibit to this Agreement.

4.   OWNERSHIP.

     IONA's license of the Products and Documentation under this Agreement will
not constitute a sale of any title or interest in the Products.  IONA will
retain all right, title and interest in and to the Products and all copies
thereof.  No right or license, other than the rights expressly granted herein,
is granted by implication or otherwise.

5.   FEES AND PRICES.

     5.1  FEES.  BroadVision will pay the fees for the Products and the
maintenance fees set forth on Exhibit A in U.S. Dollars.  For Products sold and
sublicensed to resellers or End Users in Application Development Kits,
BroadVision agrees to make and pay royalties as set forth in Exhibit A based on
the number of copies of Products made by or on behalf of BroadVision.  For
Products sold and sublicensed to resellers or End Users in Run Time Products,
BroadVision shall pay the fees set forth in Exhibit A.

     5.2  TAXES.  BroadVision's payments required hereunder are exclusive of

all sales, use, rental receipt, personal property or other taxes and their
equivalents which may be levied or assessed in connection with the use,
manufacture or sale of the Products or the Final Products.

     5.3  FORECASTS.  Upon IONA's written request, which may be provided no more
than two times in a calendar year, BroadVision will provide to IONA, within
twenty (20) days of IONA's request, an annual forecast of the number of copies
BroadVision intends to make of the Products and Final Products and whether such
copies will be used in Application Development Kits or Run Time Products.

     5.4  REPORTING.  Within ten (10) days following the end of each calendar
quarter, BroadVision shall render to IONA a statement showing in reasonable
detail the number of copies of the Products made and the number of copies of the
Products sold and sublicensed during such quarter.  BroadVision shall pay IONA
the applicable license fee for a sale and sublicense to a reseller or End User
within forty-five (45) days of BroadVision's delivery of the Final Product to
such reseller or End User.  In BroadVision's invoice for each sale and
sublicense, BroadVision will disclose the identity of each End User.

     5.5  RECORDS AND INSPECTION RIGHTS.  BroadVision will keep and maintain,
for a period of three (3) years, proper records and books of account relating to
BroadVision's marketing and distribution of the Products.  IONA may inspect such
records to verify BroadVision's statements.  Any such inspection will be
conducted only by independent public accountants during regular business hours
at BroadVision's offices in a manner that does not unreasonably interfere with
BroadVision's business activities.  Such inspection shall be at IONA's cost and
expense; PROVIDED, HOWEVER, if the audit reveals overdue payments in excess of
fifteen percent (15%) of the payments owed to date, BroadVision shall pay the
cost of such audit(s) and for each such audit IONA may conduct another audit
during the same twelve (12) month period.  Except as set forth above, such
audits may be conducted no more than once in any twelve (12) month period.  In
the event that IONA wishes to inspect such books and records, BroadVision will
make all relevant records available, including but not limited to all records
relating to activities outside of the United States (whether such records were
originally generated within or outside of the United States).  IONA will have no
right to inspect any materials not relating directly to the copying of the
Products or the distribution and marketing of the Final Products hereunder.  In
no event may IONA commence an inspection of any statement later than two (2)
years from the date of such statement.

          (2)  For questions arising from BroadVision's internal use of the
Products, IONA will provide first line telephone support to BroadVision and its
employees.

          (3)  For questions arising from End User's use of the Products, IONA
will provide second line telephone support to BroadVision.  Before contacting
IONA with End User's questions, BroadVision will first provide all End User
support that it is commercially reasonable for a competent engineering team to
provide without having access to the program's source code.  IONA may redirect
any End Users' calls it receives to BroadVision.

     Should BroadVision require support for problems not caused by IONA, such as
hardware failures, communications failures, or failures due to BroadVision
Products or non-IONA software product failures, BroadVision will pay IONA's fees
as set forth in IONA's then current price list.

     For the fees as set forth in Exhibit A, IONA will provide the support
described in this Section 6(a) twenty-four (24) hours a day, seven days a week.
At IONA's discretion, coverage between 5 p.m. and 8 a.m. weekdays and on
weekends local Ireland time may be provided by a trained technician accessible
by beeper.

     For any warranty, maintenance or support service provided by IONA to
BroadVision, BroadVision shall provide reasonable site and system access
(including remote access) reasonably necessary to IONA's performance of the
work.

     Nothing in this Agreement shall be construed to require IONA to support
versions of the Products that have been rendered non-current by subsequent
versions.  IONA will provide six (6) months prior written notice to BroadVision
before it ceases to provide support for a particular version of a Product.

     (b)  BUG FIXES.  After the expiration of the warranty period, IONA will
provide bug fixes to the Products to ensure that the Products materially conform
to the Documentation.

     (c)  NEW RELEASES.  IONA will provide BroadVision with any new versions of
the Products, including releases that ensure Product compatibility with new
versions and releases containing significant new features.

7.   PRESS RELEASE.

     The parties agree to release a cooperative press release about the release
of Final Products, with a significant focus on the Products and their role in
the Final Products.  Neither party will release such a press release without the
other party's prior written permission.

8.   TRADEMARKS; MARKINGS.

     8.1  TRADEMARKS AND TRADE NAMES.  During the term of this Agreement, in
connection with advertising, promotion and marketing of the Final Products and
in related product brochures and other materials, each party may use the
trademarks, trade names and other marketing names used by the other party in
connection with the Products or Final Products


                                     7

<PAGE>

(the "Trademarks").  In the event that a party ceases using a Trademark, such
party will provide the other party with sixty (60) days prior written notice;
after the expiration of the sixty (60) day period, the notified party shall
cease using the Trademark and shall have ninety (90) additional days to sell
through its inventory of pre-printed materials containing such Trademarks. 
IONA grants no other rights than expressly granted hereunder, and BroadVision
acknowledges IONA's exclusive ownership of such marks and names and the
renown of IONA's marks and names worldwide.  BroadVision grants no other
rights than expressly granted hereunder, and IONA acknowledges BroadVision's
exclusive ownership of such marks and names and the renown of BroadVision's
marks and names worldwide.  Each party agrees not to take any action
inconsistent with the other party's ownership and further agrees to cooperate
with, at its expense, any reasonable action, including without limitation,
the conduct of legal proceedings, which the owning party deems necessary to
establish and preserve such party's exclusive rights in and to its Trademarks
and trade names.  Anything herein to the contrary notwithstanding, if a party
has a reasonable belief that a Trademark may infringe a third party's rights,
such party may require the other party to stop using such Trademark.

     8.2  MARKINGS.  Any reproduction of Trademarks, logos, symbols and other
identifying marks will materially conform to the original design.  Each party
agrees that it will not remove or make or permit alterations to any labels or
other identifying markings placed on any Product or Documentation.

     8.3  USE OF MARKS AND NAMES.  Either party may use the other party's
Trademarks, logos, symbols and other identifying marks in advertising and
promotional materials, including any professionally mastered marketing
materials, subject to the other party's prior written approval, which approval
will be provided within ten (10) business days after receipt of the request and
will not be unreasonably withheld.  IONA acknowledges and agrees that
BroadVision may use the term "CORBA" without prior permission; provided that
BroadVision will provide IONA with copies of any of BroadVision's professionally
mastered marketing materials that include the term "CORBA"; and provided
further, that in the event that BroadVision uses "CORBA" in any professionally
mastered marketing materials, BroadVision will also use one or more of IONA's
Trademarks in such material.

     8.4  STANDARDS.  The licenses regarding the Trademarks granted hereunder
may be terminated in whole or in part by written notice if, at any time, in the
opinion of the licensing party, the marketing of Products, advertising or
promotional materials or packaging or design work for the same do not meet such
party's then current standards for the Products or Final Products.
Notwithstanding the foregoing, in the event the licensing party believes such
standards are not being met, the parties will discuss the deficiencies and
attempt to resolve them promptly.

     8.5  REFERENCE SITE.  IONA may direct any press inquiries about the
Products to BroadVision.  BroadVision will use commercially reasonable efforts
to respond to such inquiries.  BroadVision may objectively critique the Products
or IONA.  BroadVision agrees not to unjustifiably criticize IONA or the Products
or to make unjustifiable invidious comparisons between the Products and
competitive products or IONA and its competitors.

9.   WARRANTIES.

<PAGE>

     9.1  LIMITED WARRANTY.  IONA warrants that, for the period of ninety (90)
days following installation on BroadVision's or End User's computer systems, as
applicable, the Products will materially conform to the Documentation.  End
Users' and BroadVision's sole remedies for failure of a Product to meet this
warranty will be limited to having IONA use commercially reasonable efforts to
correct documented nonconformances within five (5) business days and, if IONA is
unable to correct such nonconformances within thirty (30) business days, IONA
shall refund all license fees it has received pursuant to Section 5.1.  IONA
DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
FREEDOM FROM THIRD PARTY INFRINGEMENT CLAIMS.

     9.2  NO ADDITIONAL WARRANTIES TO END USERS.  BroadVision will make no
warranties to End Users on behalf of IONA other than as set forth in
Section 9.1, and agrees to indemnify and hold IONA harmless from any third
party claims based on warranties given in violation of this Agreement.

     9.3  EXCLUSIONS.

          (a)  IONA's warranty does not cover loss or damage which (i) is due to
improper installation or maintenance by any person other than as authorized by
IONA, misuse, neglect, or any cause other than ordinary commercial or industrial
application; (ii) is due to adjustment, repair or modification by any person
other than as authorized by IONA; (iii) is due to storage or use in an improper
environment, excessive or inadequate heating or air conditioning and electrical
power failures, surges or other irregularities; or (iv) is due to any statement
about the Products other than as provided in this Agreement or in IONA's
documentation, unless confirmed in writing by IONA.

          (b)  IONA does not warrant that the Products will meet BroadVision's
or End Users' requirements, that operation of the Products will be uninterrupted
or error-free, or that all software errors will be corrected.  IONA is not
responsible for problems caused by any computer hardware or computer operating
systems (including BroadVision Products) which are not compatible with the
system specifications required to run the Products as set forth in the Product's
user manual, or for problems in the interaction of the Products with non-IONA
software (including any applicable BroadVision Products).

10.  LIMITATION OF LIABILITY.

     NEITHER PARTY WILL BE LIABLE TO THE OTHER PARTY, END USERS OR ANY OTHER
ENTITY CLAIMING THROUGH OR UNDER THE OTHER PARTY OR END USERS FOR ANY LOSS OF
PROFITS OR INCOME, LOSS OF DATA, OR OTHER TANGIBLE BUSINESS LOSS OR OTHER
CONSEQUENTIAL, INCIDENTAL, OR SPECIAL DAMAGES OR FOR ANY CLAIM BY ANY OTHER
PARTY, WHETHER IN AN ACTION IN CONTRACT OR TORT OR BASED ON A WARRANTY, EVEN IF
SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING OUT OF
OR IN CONNECTION WITH THE USE OF THE LICENSES GRANTED HEREUNDER.  IN NO

right existing or issued as of the Effective Date.  IONA will indemnify
BroadVision for all losses, damages and all reasonable expenses and costs
incurred by BroadVision as a result of a final judgment entered against
BroadVision in any such claim, action, suit or proceeding; provided that
BroadVision gives IONA prompt written notice of any such claim, grants IONA
control of the defense and any settlement thereof, and reasonably cooperates
with IONA at IONA's expense.

          (b)  If the Products, in whole or in part, are or in IONA's opinion
may become, the subject of any claim, action, suit or proceeding for
infringement of, or if it is judicially determined that the Products, in whole
or in part, infringe any third party's U.S. copyright or patent right, or if the
Product's use is enjoined, then IONA shall, at its option and expense:
(i) procure for BroadVision the right to continue the Product's sale and use;
(ii) replace or modify the Product so as not to infringe such third party's
copyright or patent right while conforming, as closely as possible, to the
Documentation; or (iii) terminate this Agreement as to such Products and refund
the license fees paid for such Products, pro rated over a five (5) year term
from the Effective Date.  The foregoing remedial actions do not relieve IONA
from its obligations under Section 11.1(a).

     11.2 LIMITATION ON LIABILITY/EXCLUSIVE REMEDY.

          (a)  IONA will have no liability under Section 11.1 for any
infringement claim based upon: (i) the use or combination of the Products with
software, hardware, or other materials not provided by IONA; (ii) components or
software which were not manufactured by IONA; (iii) any use of an unauthorized
altered version of the Products; and (iv) the use of a superseded version of the
Products, if such infringement would have been avoided by the use of a current
version.

          (b)  SECTION 11 STATES IONA'S ENTIRE OBLIGATION AND LIABILITY WITH
RESPECT TO ANY CLAIMS OF PATENT, COPYRIGHT OR OTHER PROPRIETARY RIGHT
INFRINGEMENT.

12.  BROADVISION'S INDEMNITY.

     BroadVision will, at its own expense, defend and hold harmless IONA against
any third party claim, action, suit or proceeding alleging that any BroadVision
Product furnished and used within the scope of this Agreement or the use, sale
or other disposition thereof, infringes any U.S. copyright or patent right
existing or issued as of the Effective Date.  BroadVision will

indemnify IONA for all losses, damages and all reasonable expenses and costs
incurred by IONA as a result of a final judgment entered against IONA in any
such claim, action, suit or proceeding; provided that IONA gives BroadVision
prompt written notice of any such claim, grants BroadVision control of the
defense and any settlement thereof, and reasonably cooperates with
BroadVision at BroadVision's expense.

Effective Date, but this Agreement will automatically renew for additional three
(3) year terms unless terminated earlier (a) by either party by delivering
written notice to the other prior to: (i) six (6) months preceding expiration of
the term of this contract, or (ii) any renewal of such term, or (b) in
accordance with Section 14.  Nothing in this Agreement will be construed as
requiring either party to renew or extend this Agreement.

the other party, terminate this Agreement upon the occurrence of any one or more

                                 EXHIBIT A

                    SUPPLEMENTAL TERMS AND CONDITIONS

1.   PRODUCTS AND PLATFORMS.

Graphics IRIX or Windows NT.  BroadVision acknowledges that it accepted the
Products enumerated in the foregoing sentence on February 28, 1995.  By July 1,
1995, as part of the Products and for no additional license fees, IONA will
provide versions of its Orbix product that support multi-threading on the

     1.3  PRODUCTS.  Subject to the delivery schedule in Section 1.2 of this
Exhibit A, the Products are the Orbix product in the Solaris, DEC, OSF/1, HP-UX,
Silicon Graphics IRIX or Windows NT platforms.

     1.4  TERRITORY.  The Territory shall be worldwide.

2.   FEES.

     2.1  INTERNAL USE OF PRODUCTS.  BroadVision shall pay the license fee set
forth in Exhibit B for licensing the Products for BroadVision's internal use.
BroadVision agrees to purchase [*] copies of Products for its internal use.

     2.2  APPLICATION DEVELOPMENT KIT LICENSES.  BroadVision shall pay [*]
percent ([*]%) of the applicable list price set forth in Exhibit B for each copy
of the Products sold and sublicensed in Application Development Kits to
resellers or End Users.

     2.3  PRICE INCREASES.  IONA in its discretion may increase the fees for
copies of the Products used in the Application Development Kits set forth in
Exhibit B on each annual anniversary of the Effective Date by providing sixty
(60) days' prior written notice.  In no event shall the year-to-year percentage
increase in such fees exceed the corresponding year-to-year percentage increase,
plus five percent (5%), in the Retail Price Index measured from January to
January.  However, in the event of major changes in the currency exchange rate
between the Ireland Punt and the U.S. Dollar, the parties agree to negotiate in

<PAGE>

Products less any reseller discounts.  The initial license fees to be charged
to End Users by BroadVision for the Run Time Products will be as set forth
in Exhibit C.

     2.5  VERSION 2.0 RUN TIME PRODUCT LICENSE.  It is the parties' intent to
move to a modular pricing structure upon BroadVision's release of Version 2.0 of

attributable only to the individual module which allows the user to actually
utilize the Product's functionality.  Upon BroadVision's release of a Run Time
Product it enumerates, in its sole discretion, as version 2.0, BroadVision will
pay to IONA [*] percent ([*]%) of the gross license fees attributable to
BroadVision's sale and sublicense of the individual module which allows the User
to actually utilize the Product's functionality less any reseller discounts.
Notwithstanding the foregoing, if BroadVision has not released a Run Time
Product it enumerates as version 2.0 within thirty (30) months from the
Effective Date, the parties agree to renegotiate the fees applicable to the Run
Time Products.

     2.6  MAINTENANCE AND SUPPORT FEES.  For 8:00 a.m. to 5:00 p.m. support for
Products for BroadVision's internal use, the annual maintenance and support fee
shall be twelve and a half percent (12 1/2%) of the Internal Development License
fee set forth in Exhibit B for each copy of the Product licensed.  For 8:00 a.m.
to 5:00 p.m. support for Products for BroadVision's resale, the annual
maintenance and support fee shall be four percent (4%) of the Resale Development
License fee set forth in Exhibit B for each copy of the Product licensed.  All
fees under this Section 2.6 are payable in advance on the expiration of the
applicable warranty period and each anniversary thereof.  For 24 hours per day,
seven days a week support as described in Section (6a), the Parties shall use
their best efforts to negotiate the applicable fee when customer requirements
for such support arise.

     -    SINGLE SERVICE PROVIDER (SSP)

          An SSP is generally a content provider developing a single application
          for use across one or more on-line platforms.  Content providers span
          a wide range of industries, including media and entertainment, retail
          and catalog sales consumer goods, travel services, and more.  Examples
          of leading companies developing services include AA/Sabre, Disney,
          Fingerhut, Lands End,  Macy's Interactive, QVC, Times-Mirror and
          Viacom.

     -    MULTIPLE SERVICE PROVIDER

          An MSP is generally a network operator or network access provider that
          is aggregating a suite of applications into a package of ITV or on-
          line services.  MSPs develop applications and also strike deals with
          SSPs. Examples of MSPs include unregulated subsidiaries of all the
          U.S. RBOCS and telephone companies, international telecommunications
          firms, cable companies, major on-line services.

     -    SYSTEMS INTEGRATORS

          Systems integrators contract with SSPs and MSPs to build the software
          and hardware platforms necessary for delivering on-line and
          interactive services. Systems integrators playing a strong role in the
          interactive markets include AT&T, Cap Gemini, Arthur Andersen, EDS,
          Lockheed, Logica, SHL Systemhouse and Siemens.

     -    PLATFORM VENDORS

          Platform vendors offer end-to-end solutions for interactive and on-
          line services.  Platform vendors may choose to integrate or OEM
          CoMarket software into their platform for sale to service providers,
          or they may work in a co-marketing partnership with BroadVision.
          Leading platform vendors for interactive and on-line services include
          DEC, HP, ICTV, IDS, Intel, MEI, Microsoft, NetScape, Oracle, Spry and
          Sun, Sun/Thompson, Sybase, Tandem.

DESCRIPTION OF LICENSEES

BroadVision offers three types of licenses for CoMarket, depending on the type
of customer and their use of the product.  These include:

     -    COMARKET TOOLKIT DEVELOPERS


                                     C-1

<PAGE>

          Developers are companies with the rights to develop applications using
          BroadVision products.  Developers are licensed to use the CoMarket
          Toolkits and embed the CoMarket APIs in applications.

     -    COMARKET DASHBOARD USERS

          Dashboard end-users are companies with the rights to use the CoMarket
          Dashboard in an operational environment.

     -    COMARKET OPERATORS

          Operators are companies with the rights to execute applications
          developed using the CoMarket Toolkits and operate the CoMarket ICMS.
          There are two types of operators, Single Service Providers (SSPs) and
          Multiple Service Providers (MSPs), as defined below:

          -    SINGLE SERVICE PROVIDER (SSP)

               An SSP is a company providing an Interactive Service Application,
               such as an electronic catalog, games service, etc.  An SSP
               generally operates only one service on an interactive network,
               either as a stand alone application or as part of an MSP package.

          -    MULTIPLE SERVICE PROVIDER (MSP)

               An MSP is a company developing and providing multiple interactive
               applications as part of a total package.  Examples include
               providers of  ITV platforms, such as RBOCs, cable companies and
               Direct Broadcast Satellite (DBS) operators, as well as providers
               of on-line services or electronic malls.

     -    COMARKET RESELLERS

          Resellers are companies with the rights to sub-license BroadVision
          products.  Resellers may include MSPs offering BroadVision tools as
          part of their platform development environment, systems integrators,
          or other software companies.

PRODUCT LICENSES

The product is licensed based on the components used.  There are three types of
licenses:

     1.   COMARKET TOOLKITS LICENSE


                                     C-2

<PAGE>

          The Toolkit license includes documentation, example programs and code
          comprising the CoMarket Application Programming Interfaces (API).  The
          Toolkits are licensed on a per developer basis, and include:

          -    The Application Integration Toolkit, including platform-specific
               software stubs for integration of the ICMS with interactive
               applications

          -    The Existing Business Systems Toolkit, including platform-
               specific software drivers for integration of the ICMS with
               existing business systems

Both toolkits include documentation and sample programs.  The CoMarket APIs are
provided as a C++ library.  The CoMarket Toolkit license includes the right to
incorporate both the software stubs and drivers in interactive applications and
existing business systems, and the right to sub-license such applications to
others.

     2.   COMARKET DASHBOARD LICENSE

          The Dashboard license provides operators of interactive applications
          the right to use the CoMarket Dashboard.  Dashboards are licensed on a
          per seat basis. The Dashboard provides marketing and back office
          operators the ability to define and implement new prices, pricing
          rules, discounts and incentive programs, create reports from data in
          the Application Observation System, add, modify and update marketing
          programs.

     3.   COMARKET ICMS LICENSES

          The CoMarket ICMS provides the interactive application access to the
          functionality supplied by the ICMS subsystems in an operational
          environment.  An ICMS may support one or more interactive applications
          and many consumer sessions.  The ICMS is licensed based on the number
          of consumer sessions.  Initially, the product will be sold as a single
          package (e.g. all subsystems sold in the package).  Over time, a
          component-based approach will be supported, allowing ICMS subsystems
          to be purchased on a modular basis.

COMARKET RELEASE AND CONFIGURATION PLAN

     1.   CoMarket V1.0, scheduled for release in December 1995, will consist of
          all ICMS subsystems configured as one package.  The CoMarket Toolkits
          and CoMarket Dashboards, licensed separately, will support the
          functionality provided in V1.0 of the ICMS.

     2.   BroadVision's second release (CoMarket V1.5), scheduled for the second
          half of 1996, will consist of enhanced versions of the subsystems
          contained in V1.0, and additional subsystems containing new
          functionality.  CoMarket V1.0 will also be configured as a single
          package.  Customers using V1.0 can upgrade to V1.5 by paying the
          incremental difference in price between the two releases. The CoMarket
          Toolkits and CoMarket Dashboards, licensed separately, will also be
          enhanced to support the new functionality provided in V1.5 of the
          ICMS.

     3.   BroadVision's third release (CoMarket V2.0), scheduled for 1997, will
          be priced on a per subsystem basis and not as a set package.  CoMarket
          V2.0 will include enhancements to existing subsystems and new
          functionality provided through additional subsystems.   The CoMarket
          Toolkits and CoMarket Dashboards, licensed separately, will be
          enhanced to support the new functionality provided in V2.0 of the
          ICMS.  These products will only support access to the ICMS subsystems
          licensed for use.
