ACCESS and ISG will record the installation of each copy of the Licensed Works
for which license fees are payable, using

                            CONFIDENTIAL TREATMENT

                                      -5-
<PAGE>

the procedures described in Section 4.4. After the end of each quarter, ISG will
deliver to ACCESS a statement setting forth the calculation of the Utilization
Amount, the Committed Amount and the Carryover Amount for the quarter. ACCESS
will pay to ISG within 45 days of receipt of such statement the amount, if any,
by which (i) the Utilization Amount for the quarter minus the Carryover Amount
                                                    -----
for the quarter exceeds (ii) the Committed Amount for the quarter.

               4.2.2. The following terms used in Section 4.2.1 have the
following meanings:

              "Committed Amount" means, for any quarter, the amount so
designated for such quarter in Schedule I.

              "Utilization Amount" means, for any quarter, the amount of
license fees that would be payable for all copies of Licensed Works installed
during the quarter, calculated in accordance with Section 4.1 and reflecting any
increase or decrease pursuant to Section 4.2.3.

              "Carryover Amount" means, for any quarter, the amount (if any) by
which (i) the sum of the Committed Amounts for all preceding quarters exceeds
(ii) the sum of the Utilization Amounts for all preceding quarters. The
Carryover Amount shall be retroactively adjusted to reflect any retroactive
price adjustments required by Section 4.2.3.

              4.2.3. The obligation of ACCESS to pay Committed Amounts shall be
subject to compliance by ISG with its obligations hereunder and shall terminate
upon any termination of this Agreement. ACCESS shall have the following options
to change its obligations to pay the Committed Amounts and the pricing of
Licensed Works.

              Option 1. ACCESS may cancel its obligations to pay the Committed
              --------
Amounts for the quarter ended June 30, 1998 and all subsequent quarters upon
notice to ISG delivered on or before June 29, 1997. The obligations of ACCESS to
pay the Committed Amounts for the quarter ending on March 31, 1998 and all prior
quarters will be unaffected by exercise of this option. Upon exercise of this
option, the license fees for Licensed Works will be changed from those shown in
Table 1 of Schedule I to those shown in Table 2 of Schedule I, and Utilization
Amounts and the Carryover Amount shall be calculated on this basis. This change
will apply retroactively to all copies of Licensed Works installed after the
effective date of this Amended and Restated

                            CONFIDENTIAL TREATMENT

                                      -6-
<PAGE>

Reseller Agreement and ACCESS will pay, upon invoice by ISG following exercise
of this Option 1, the amount (if any) by which (i) the payments that would have
been made under Section 4.2.1 for prior quarters based upon Table 2 of Schedule
I exceed (ii) the amounts actually paid by ACCESS during such prior quarters.

              Option 2. ACCESS may cancel its obligations to pay the Committed
              --------
Amounts for the quarter ended June 30, 1999 and all subsequent quarters upon
notice to ISG delivered on or before September 15, 1998. The obligations of
ACCESS to pay the Committed Amounts for the quarter ending on March 31, 1999 and
all prior quarters will be unaffected by exercise of this option. Upon exercise
of this option, the license fees for copies of Licensed Works installed after
March 31, 1998 will be changed from those shown in Table 1 of Schedule I to
those shown in Table 2 of Schedule I, and Utilization Amounts and the Carryover
Amount shall be calculated on this basis. This change will not be retroactive.


              If neither Option 1 nor Option 2 is exercised, the license fee
for the VRS NT 200 (v1.1) application will be reduced to zero for all copies
installed after September 15, 1998. If ACCESS shall deliver to ISG an
irrevocable waiver of ACCESS's rights to exercise Option 1 and Option 2 (which
may be delivered after Option 1 has expired), the license fee for the VRS NT 200
(v1.1) application will be reduced to zero for all copies installed after the
date of the waiver. ACCESS may at any time elect to reduce the license fee for
the VRS NT 200 (v1.1) application to zero by notice to ISG accompanied by
payment of a reduction fee of [*THE CONFIDENTIAL PORTION HAS BEEN OMITTED AND
FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.] Such a reduction
will be effective for all copies of the VRS NT 200 (v1.1) application installed
after the date of notice and payment.


          4.3  After termination of the obligations of ACCESS to pay Committed
Amounts ACCESS shall nonetheless have the rights to resell ISG Devices and
license the Licensed Works as set forth herein for the remaining term of this
Agreement. After any termination of the Committed Amount obligations, license
fees for the Licensed Works shall be calculated in accordance with Sections 4.1
and 4.2.3 and shall be paid monthly upon invoice by ISG for Licensed Works
installed during each month. Any Carryover Amount remaining after termination of
the Committed Amount obligations shall be applied on a first dollar basis to
reduce license fees otherwise payable.

<PAGE>

          4.4  Within 15 business days of the end of each month, ACCESS will
deliver to ISG a written statement setting forth a list of all ISG Devices
shipped or installed during the month, the Licensed Works included in such ISG
Devices, the name and address of the end user site for each device, a contact
name and telephone number for each end user, and the host ID of each system on
which Licensed Works are installed. These statements will be the basis for
quarterly statements of utilization required by Section 4.2.1 and the monthly
invoices required by Section 4.3. Terms and conditions for all ISG Devices
ordered hereunder shall be in accordance with this Agreement and shall not be
modified by any terms of ACCESS's purchase order or other forms or ISG's
invoice, bill of lading, installation certificate or other forms. Payment of all
invoices shall be due 45 days from receipt of invoice. Amounts overdue beyond
this limit will bear interest at the rate of 1% per month.

          4.5  ACCESS shall maintain complete and accurate records of each ISG
Device sold and each copy of Licensed Works installed hereunder, including
without limitation all records required for compliance with FDA regulations. ISG
may, not more often than twice in any period of twelve consecutive months,
conduct a review of the records of ACCESS relating to ISG Devices and Licensed
Works, at reasonable times and upon reasonable notice. ISG shall bear its own
costs incurred for any such audit unless the audit results in a determination of
a discrepancy of more than 10% between license fees payable as originally
reported by ACCESS and license fees actually payable for Licensed Works
installed by ACCESS for the period covered by the audit, in which case ACCESS
shall pay the reasonable out of pocket costs of the audit. All information made
available by ACCESS under Section 4.4 or this section 4.5 shall be treated as
confidential in accordance with Section 6.2 and shall not be used for any
purpose other than determination of the amounts payable under this Agreement.

          4.6  Prices do not include sales tax or similar taxes. ACCESS shall
pay such taxes either directly or when invoiced by ISG, or shall supply
appropriate tax exemption certificates in a form satisfactory to ISG.

          4.7  Payments to ISG shall not be deemed to have been made until the
funds are available to ISG in Mississauga, Ontario, Canada.  Alternatively, if
ACCESS is prevented by government regulations from transferring funds to
Canada, ISG shall have the right to require ACCESS to deposit the blocked funds
or an equivalent amount denominated in another currency due to ISG in a bank and
country designated by ISG and for ISG's account.

          4.8  ACCESS shall be responsible, at its own expense, for obtaining
all necessary import permits and for the payment of any and all taxes and duties
imposed on the delivery, importation, sale or license of the ISG Devices and
Licensed Works in locations designated by ACCESS; except that ISG shall be
responsible for complying with all regulations or other measures promulgated by
the FDA under the Food and Drug Act which are required to be complied with for
the importation of ISG Devices into the United States.

          4.9  If any copy of Licensed Works installed on an ISG Device is lost
or is so damaged as to be unusable prior to delivery of such ISG Device to the
customer, ISG will permit installation of a replacement copy of such lost or
damaged Licensed Works without payment of an additional license fee.

     5.   SUPPORT.

          5.1  ISG will supply the following materials to ACCESS:

              5.1.1  Five copies of the latest object code or executable code
for the GMA Release version of each item included in the Licensed Works, with
updates as provided in Section 5.2.3. Each copy of Licensed Works will enable
ACCESS to install and integrate such Licensed Works on ISG Devices, and will
enable users to use such ISG Devices for an unlimited time, without requiring
any activation or other action by ISG. If a copy of the Licensed Works initially
provided is lost, damaged or destroyed, ISG will provide at cost a replacement
copy, which may be a more recent release or version.

              5.1.2 Either (i) for each ISG Device for which a license fee is
recorded, one copy of documentation in English and documentation updates as they
are prepared and released which, when taken together, constitute complete
documentation for the ISG Devices complying with the requirements of the Food
and Drug Act and the regulations and other measures promulgated by the FDA
thereunder or (ii) all materials necessary to permit ACCESS to produce
documentation as set forth in clause (i), which will include soft copy of text
and updates as well as art work for covers, backs and spines of user manuals.

              5.1.3  Five copies of all installation scripts and procedures
necessary or appropriate for installation of the GMA Release version of each
item of Licensed Software on ISG Devices.

              5.1.4  Five copies of any modifications to the Licensed Works
(with revisions to the documentation to reflect such modifications) which are
provided to other customers of ISG without charge and are not proprietary to
such customers.

          5.2  ISG will provide the following support:

              5.2.1  ISG will make support as provided in this Section 5.2
available for each ISG Device for the duration of the Support Period for such
device, subject to payment of support fees as provided herein. ISG will at all
times support the current release of each of the Licensed Works and the
immediately preceding Major Release of each of the Licensed Works. ISG will
support each Major Release of VRS UNIX Software for at least 12 months from the
date of GMA Release, regardless of the number of additional releases during such
period. After June 30, 1998, ISG will support each Major Release of VRS NT
Software for at least 12 months from the date of GMA Release, regardless of the
number of additional releases during such period. A "Major Release" is a release
of a Licensed Work which has undergone full GMA Release procedures and is
identified by the first two numerals in a version number (that is, "x.y").

              5.2.2  ACCESS will provide first line support to its customers.
In the event of a problem, ACCESS's end customer will contact ACCESS with
problems, queries and/or help line requests. Trained ACCESS customer service
personnel will respond to calls and attempt to diagnose and repair problems
according to procedures defined in ISG's training courses and documentation.
ACCESS will contact ISG only after having done so without resolving the problem,
with such contact being made as defined for the relevant geographical territory
and the problem being logged in accordance with an agreed procedure. ISG will
then provide second line support. ISG will issue a Customer Service Order Number
and one or more of the following courses of action will be taken as deemed
appropriate by ISG technical support staff:

              i)   Technical or applications support via telephone to trained
ACCESS service personnel.

              ii)   In depth problem investigation and analysis via modem to end
customer system.  This support is provided only where direct high speed modem
access is available via a dedicated telephone line.

                                      -10-
<PAGE>

              iii)   A monthly problem report will be provided to ACCESS
detailing the Customer Service Order Number, date and type of call and
resolution of each support call.

              iv)   On site consultation is available upon request at then
applicable ISG standard time and materials rates and is subject to availability
of technical or applications support personnel.

              v) Five master copies of software updates will be provided from
time to time to ACCESS, as provided in Section 5.2.3 below.

              5.2.3  In providing maintenance support, ISG shall:

              i)  Respond to and verify any alleged errors in the
documentation or code upon notification by ACCESS; and

              ii)  Provide resolution of defects as detailed below:

                   1.  Safety - Deficiency affects patient safety or FDA
         reportable defects.

                   2.  Critical - Deficiency causes the VRS application to fail
         catastrophically.

                   3.  Urgent - Deficiency causes the VRS application to give
         erroneous, distorted or severely deficient function from which users
         must be isolated.

                   4.  Serious to Minor - Deficiency similar to level 3 above,
         but for which a work-around can be implemented allowing the user to
         achieve the desired accuracy or function, with minor inconvenience, or
         deficiency causes minor inconvenience, but is a definite deficiency
         against specification.

                   5.  Improvements - ACCESS requests new functionality not
covered by specification.

For priority levels 1, 2 and 3, ISG will immediately take corrective action and
provide a validated bug fix, in the form of an update, within a reasonably
expeditious time frame.

                                      -11-
<PAGE>

For priority level 4, ISG will take corrective action and provide a validated
bug fix, in the form of an update, without charge, within a reasonable time
frame.

For priority level 5, ISG will determine in its good faith judgment whether the
requested functionality is appropriate for inclusion in the next general release
to customers.  If ISG so determines, ISG will provide an update to ACCESS
without charge.  If ISG does not so determine, ISG will provide the requested
modification at ISG's standard charges.


              5.2.4   ACCESS will pay support fees of [*THE CONFIDENTIAL
PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION.] to be invoiced on June 30, 1997 and [*THE CONFIDENTIAL PORTION HAS
BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.]
to be invoiced on June 30, 1998. ACCESS and ISG will, not less than annually,
review the foregoing support fees and the records of both parties relating to
service provided to customers, and will discuss in good faith whether any change
in such fees is appropriate in light of the time and effort actually expended by
ISG on support under this Agreement. Prior to March 31, 1999, ACCESS and ISG
will negotiate pricing for support to be provided by ISG after that date. ISG
will in any event make support available after that date to the extent provided
in this Agreement at ISG's then applicable time and materials charges.


          5.3  ISG hereby certifies the compatibility only of the hardware and
systems configurations listed in Schedule I for inclusion in ISG Devices on
which Licensed Works are installed. ISG will cause the Licensed Works to be
compatible with, and will certify to ACCESS that ISG Devices may include:

              (i)  At all times during the term of this Agreement prior to the
    UNIX Termination Date, the release of the Sun Solaris operating system
    immediately prior to the then most current release.

              (ii) At all times during the term of this Agreement on or after

    necessary to correct a defect of Level 3 or higher (as defined in Section
    5.2.3(ii)), ISG will provide the necessary support. The "UNIX Termination
    Date" means a date of which ACCESS is notified at least twelve months in
    advance, on which ISG shall cease to make VRS UNIX Software available to
    customers.

              (iii) At all times during the term of this Agreement, the
    release of the Windows NT operating system immediately prior to the then
    most current release.

         ISG Devices including any of the systems and components set forth
above, and Licensed Works installed thereon, shall be covered by all support
obligations, representations, warranties and agreements of ISG contained herein.

         5.4  While it is acknowledged that the ISG Devices may be used in
certain surgical, medical life support or other applications of a similar degree
of potential hazard, ACCESS acknowledges that ISG Devices are not designed or
intended to substitute for or override the training, experience and knowledge of
end users.

    1.   ADDITIONAL COVENANTS.

         6.1  ACCESS shall include in all copies of Licensed Works made by
ACCESS any copyright or similar notice as furnished by ISG to ACCESS.

         6.2  Each party hereto covenants that it shall keep confidential any
confidential information relating to the other party's business, finances,
marketing and technology to which it obtains access (including without
limitation the Licensed Works and the pricing and other terms of this Agreement)
and that it shall take all reasonable precautions to protect such confidential
information of the other party or any part thereof from any use, disclosure or
copying except as expressly authorized by this Agreement.  The obligations of
the parties under this Section 6.2 are in addition to, and not in substitution
of, their respective obligations under the Confidentiality Agreement dated as of
March 31, 1995 between ACCESS and ISG.

         6.3  The parties agree as follows with respect to proprietary rights:

                            CONFIDENTIAL TREATMENT

                                      -13-
<PAGE>

              6.3.1  ACCESS acknowledges that, except as set forth in Section
6.3.2 below, the Licensed Works and all related information and documentation
are the property of ISG and/or third parties from whom ISG has acquired certain
rights under license.

              6.3.2  ISG acknowledges that ACCESS has provided and will
provide to ISG certain software applications, know-how and trade secrets
relating to wavelet compression and decompression of images, which are included
in Licensed Works made available to ACCESS under this Agreement. ISG agrees that
it will treat the particular specifications ACCESS has provided regarding
compression and decompression as proprietary information of ACCESS. This applies
to the specifications and concepts including the following:

         1. Non-standard DICOM transport mechanisms for image transmission

         2. Controls over the number of images in a study

         3. The use of progressive decompression

         4. Modifications to the DICOM header elements reflecting changes in
            certain data such as image matrix size and compression status

         5. Error and exception handling

         6. PPP server transmission methodologies

ISG agrees that it will not provide other customers for its workstation products
with the above information and know-how (or devices or applications including
them). Nothing in this paragraph will be construed so as to restrict ISG from
developing and/or marketing a solution similar to any or all of the ACCESS
solutions specified in items 1 to 6 above, provided that ISG has received the
specifications and/or know-how for such similar solutions from a third party
without solicitation or assistance from ISG and without any knowledge on ISG's
part that such third party is in violation of  any confidentiality obligation or
proprietary right.

         6.4  ACCESS at all times will comply with all provisions of the Food
and Drug Act and the regulations and other measures promulgated by the FDA
thereunder which are applicable to ACCESS as a distributor of ISG Devices as
contemplated by this Agreement.

         6.5  ISG represents that the ISG Devices, when configured and marketed
as contemplated by this Agreement and assuming compliance by ACCESS with its
covenant set forth in Section 6.4, will at all times comply with all applicable
provisions of the Food and Drug Act, the regulations and other measures
promulgated by the FDA thereunder, and all filings made by ISG thereunder, and
will have all necessary FDA clearances or approvals for commercial marketing in
the United States of America.  ISG will at all times comply with all provisions
of the Food and Drug Act, the regulations and other measures promulgated by the
FDA thereunder, and all filings made by ISG thereunder, which are applicable to
ISG as the manufacturer of ISG Devices distributed as contemplated by this
Agreement.

         6.6  The parties agree to the following indemnity provisions:

              6.6.1  ACCESS shall indemnify and save harmless ISG from and
against any and all liabilities, damages, costs or expenses (including
attorney's fees as incurred) resulting from any negligence or misconduct of
ACCESS in marketing or installing ISG Devices or failure to comply with ACCESS's
obligations set forth in Section 6.4.

              6.6.2  ISG shall indemnify and save harmless ACCESS from and
against any and all liabilities, damages, costs or expenses (including
attorney's fees as incurred) resulting from any negligence or misconduct of ISG
in manufacturing ISG Devices, any defect in ISG Devices installed and configured
as instructed by ISG, or any inaccuracy or failure of compliance with ISG's
representations and obligations set forth in Section 6.5.

              6.6.3  Any party seeking indemnification hereunder shall promptly
inform the indemnifying party in writing upon becoming aware of any claim for
which indemnity may be sought. Such notice shall include a statement of the
facts and circumstances relevant to such claim.  Following such notice, the
indemnifying party may participate in the defense.  Neither party shall settle
or compromise any claim for which indemnity is sought hereunder without the
prior written consent of the indemnifying party.

         6.7  At least two qualified ACCESS employees will attend two days of
service training at ISG's facility annually. ACCESS will pay a charge of $3,000
per person per year for such training. Attendance by ACCESS personnel for whom
the training charge has been paid in any year at additional new training courses
during that year will be  free of charge.

         6.8  ISG agrees to the following development obligations.

              6.8.1  ISG will release for resale by ACCESS hereunder either a
software patch for VRS UNIX 2.1 or a release of VRS UNIX 2.2 , which will in
either case include additional functionality as set forth in Schedule I. This
patch or release will be released in a beta test version by June 30, 1997 and a
GMA Release version by October 31, 1997.

              6.8.2  ISG will release for resale by ACCESS hereunder a GMA
Release version of the VRS NT-200 Release 1.1 application, having the
functionality specified in Schedule I, by May 30, 1997.

              6.8.3  ISG will release for resale by ACCESS hereunder a GMA
Release version of the VRS NT Software having the decompression functionality
specified in Schedule I by June 30, 1997.

              6.8.4  If ISG does not release any of the applications set forth
above by the date specified, payment of all Committed Amounts falling due after
the specified release date will be deferred until release occurs. During any
period of deferral, ACCESS will pay license fees as provided in Section 4.3.
Upon resumption of payment of Committed Amounts, payments made during the
deferral period will be credited on a first dollar basis against Committed
Amounts payable.


   7.    WARRANTIES.

         7.1  ISG warrants and agrees that:

              7.1.1  ISG has the full authority to grant the license and rights
set forth in this Agreement.

              7.1.2  To the best of ISG's knowledge, the documentation and
code of the Licensed Works have not been published under circumstances which
have caused loss of copyright therein, and to the best of the ISG's knowledge
the documentation and code of the Licensed Works do not infringe upon any
copyright or other proprietary right of any third party.

                                      -16-
<PAGE>

              7.1.3  ISG is not aware of any claim of infringement of any
copyright or other proprietary right having been made or pending against ISG
relative to the documentation or code of the Licensed Works.

              7.1.4  ISG will, at its expense, defend against, hold ACCESS
harmless from, and pay any final judgment against ACCESS or any ACCESS customer
arising out of any claim that the use of any Licensed Work as contemplated by
this Agreement infringed a copyright, a patent or a trade secret provided that
(i) ACCESS notifies ISG in writing of such claim or action, and (ii) ISG has
sole control of the defense and settlement of such claim or action. In defending
against such claim or action, ISG may, at its option, agree to any settlement in
which ISG shall either (1) procure for ACCESS and all ACCESS customers the right
to continue using the Licensed Works; or (2) modify or replace the Licensed
Works so that they no longer infringe, to the extent that the exercise of such
option does not result in a material adverse change in the operational
characteristics of the Licensed Works, and equivalent functions and performance
provided by ISG remain following implementation of such option. If ISG concludes
in its judgment that none of the foregoing options is reasonable, ISG may remove
the Licensed Works and any other components supplied by ISG rendered unusable as
a result of such removal and repay to ACCESS all amounts paid with respect to
the infringing products by ACCESS to ISG under this Agreement. Any such payment
shall be in addition to, and shall not diminish, ISG's obligation to defend and
indemnify against claims for infringement. Each party shall promptly notify the
other in the event that it becomes aware of a claim covered by this Section 7.1.

         7.2  The ISG Devices, when properly installed and configured, will meet
all applicable standards of the American College of Radiology for diagnostic
images and are appropriate for diagnostic radiological examinations, and ISG has
no knowledge of existing problems which would cause the ISG Devices to fail to
comply with the foregoing warranty.

   8.  TERM AND TERMINATION.

         8.1  This agreement shall have an initial term ending on March 31,
2000, subject to earlier termination as provided below.

terminate this Agreement by delivery of a separate written termination notice to
ACCESS.

              8.5.5  ACCESS shall provide a list of names and addresses of
customers who have entered into sublicenses with ACCESS since the date of this
Agreement.

         8.6  Notwithstanding any termination or expiration of this Agreement,
any sublicense granted to an ACCESS customer prior to such termination or
expiration shall survive such termination or expiration, and Sections 6.2, 6.3,

              9.2.1 Subject to ACCESS's right to grant sublicenses hereunder,

Agreement.

         9.5  If any provision of this Agreement is invalid or unenforceable in
any particular case, such case shall not invalidate or render unenforceable any
other part of this Agreement.  The Agreement shall simply be construed as not

unenforceable to the extent of the particular case, and the rights and
obligations of the parties hereto shall be construed accordingly.

         9.6  This Agreement is effective when executed by both parties.  This
Agreement may be executed in counterparts, each of which shall constitute one
and the same instrument.

         9.7  This Agreement and the Confidentiality Agreement dated March 31,

subject matter hereof and supersedes all prior agreements, understandings,
negotiations and discussions, whether oral or written, of the parties

Materials to ACCESS if and when ACCESS is deemed to have the right thereto as
determined below.

              9.10.1 Provided that ACCESS is not then in material default under

of the occurrence of any of the following events (each a "Release Condition"):

              (a)    The undisputed failure by ISG, following not less than 90
                     days written notice from ACCESS, clearly indicating the
                     nature of the default, to maintain the Licensed Works and
                     such failure results in the occurrence or continuance of a
                     defect classified as Level 1 Safety, Level 2 Critical or
                     Level 3 Urgent under Section 5.2.3 above, or if such
                     failure is disputed, the notice must be supplemented by a
                     court order resolving the dispute; or

              (b)    Proceedings shall be commenced by or against ISG under the
                     United States Bankruptcy Code or the Canadian Bankruptcy
                     and Insolvency Act and (in the case of a proceeding
                     commenced against ISG) shall not be dismissed or discharged
                     within 90 days of commencement.

              9.10.2 Upon taking possession of the Escrow Materials due to the
occurrence of a Release Condition, ACCESS agrees that such source code shall be
subject to restrictions on use, transfer, sales and reproduction placed on the
Licensed Works themselves by this Agreement.

              9.10.3 The Escrow Agreement will continue in full force and
effect, except that this Agreement shall govern any inconsistencies between this
Agreement and the Software Escrow Agreement.

              9.10.4 ACCESS shall use the Escrow Materials only for what would
otherwise be obligations of ISG to provide support of the Licensed Works. It is
expressly understood that the Software Escrow Agreement pertains to the right to
use the Escrow Materials and that no rights to ownership of the Escrow Materials
pass from ISG to ACCESS. It is also expressly understood that the Escrow
Materials are confidential and secret assets of ISG and the Escrow Materials
will be held by ACCESS and not reproduced or copied, or made available to any
third party, except in accordance with this Agreement. It is expressly
understood that the Escrow Materials will be either returned to ISG or destroyed
once the default giving rise to a Release Condition is cured and adequate
assurances of ISG's future performance are given to ACCESS. UNDER NO
CIRCUMSTANCES IS THE SOURCE CODE TO BE SOLD, TRANSFERRED OR COPIED BY ACCESS OR
ITS DISTRIBUTORS. This

LIMITATION ARTICLE 5), ISG MAKES NO WARRANTIES OF ANY KIND WITH RESPECT TO THE
ISG DEVICES, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE.  Except as otherwise set forth in this

incidental or consequential damages of any nature or kind whatsoever or for any
damages (whether caused directly or indirectly) related to loss of profits, loss
of revenue, loss of data or other economic loss in connection with, or arising
out of, the use or supply or non-supply of the ISG Devices.  Except as otherwise
set forth in this Agreement (including without limitation Articles 6 and 7), the
liability of ISG to ACCESS under this Agreement or resulting from this Agreement
under any theory of law or equity is limited to money damages not to exceed the
