                     for physical harm to persons caused by ISM's negligence)
                     even if ISM has been advised of the possibility thereof,
                     including but not limited to lost profits, lost business
                     revenue, failure to realise expected savings or loss of, or

                     secret indemnity") and article 5.0 ("Confidential
                     Information")

8.0    ISM'S PATENT, TRADE MARK AND TRADE SECRET INDEMNITY

       8.1    Subject to section 7.2, ISM will indemnify, defend and hold
              OptiMark, the OptiMark Related Companies, the Customers of each
              and the officers, directors, employees and agents of each
              (individually and collectively, the "OptiMark Indemnitees")
              harmless from and against any and all claims, causes of action,
              liabilities, damages, costs or expenses finally awarded or settled
              against them (including, without limitation, reasonable legal fees
              awarded or settled against them or any of them) arising out of or
              resulting from any claim of infringement of a patent, of a
              copyright, of a misappropriation of a trade secret or of any other
              right alleged against the OptiMark Indemnitees and arising out of
              or from the use or exploitation of the ITS Software or the
              IBM-Made Modifications in the OPS Modified Work as permitted under
              this Agreement by the OptiMark Indemnitees provided that, subject
              to the provisions set forth in section 8.2, the OptiMark
              Indmenitees promptly notify ISM of any such claim and co-operate
              with ISM in, and allow ISM to control, the defense of any such
              claim and any related settlement negotiations.

       8.2    Using counsel selected by ISM, ISM will assume, at its own cost, a
              prompt, rigorous and full defense and/or a good faith settlement
              (which seeks to maintain OptiMark's rights hereunder) of any claim
              of which ISM is responsible to indemnify under section 8.1 and
              OptiMark will cooperate reasonably with ISM in connection
              therewith; except that with respect to settlements entered into by
              ISM: (A) the consent of OptiMark will be required if the
              settlement provides for equitable relief against any of the
              OptiMark Indemnitees; and (b) ISM will obtain a full and complete
              release of the OptiMark Indemnitees from the third party
              claimant(s) concerning any claim which ISM is responsible to
              indemnify under section 8.1. ISM will keep OptiMark reasonably and
              timely apprised of the events of the defense and/or settlement
              (including without limitation the providing of copies of the
              relevant pleadings, other filings and settlement proposals) and
              ISM shall give full consideration to, and be open to discussion
              of, the views and suggestions of OptiMark (and/or its counsel as
              provided for in section 8.3) in proceeding with such defense
              and/or settlement.

                                       4
<PAGE>   5

       8.3    In the defense or settlement of any claim under section 8.1, and
              subject to section 7.2, ISM shall promptly reimburse the OptiMark
              Indemnitees for all costs, damages, expenses, legal fees and/or
              other amounts that a court of competent jurisdiction (including
              without limitation any arbitration panel or other tribunal)
              finally awards against any OptiMark Indemnitee and to timely pay
              all costs, damages, expenses, legal fees and/or other amounts
              agreed to be paid in settlement, resulting from a claim
              indemnified under section 8.1 provided further that ISM will
              permit OptiMark to participate in the settlement or defense of the
              claims through counsel chosen and paid for by OptiMark, and keep
              such counsel informed as they may request.

       8.4    In addition, if any claim or cause of action referred to in
              section 8.1 is made against an OptiMark Indemnitee's use or
              exploitation of the IBM-Made Modifications in the OPS Modified
              Work as permitted under this Agreement which occasions any
              material risk of an injunction against such use or exploitation,
              IBM will, upon notice of the claim of infringement and at no cost
              to OptiMark either, (i) obtain a license from the third party for
              the OptiMark Indemnitees to continue using the accused IBM-Made
              Modifications which shall come into effect no later than the
              earliest effective date of any such injunction; and/or (ii) modify
              the accused IBM-Made Modifications to avoid such infringement and
              use all diligent efforts which are not unreasonable to complete
              such modifications before any inlunction precluding the use
              thereof can be secured or come into effect, including securing the
              assistance of the IBM Related Companies in so doing.

       8.5    In addition to the indemnity provided in section 8.1, ISM shall
              promptly notify OptiMark in writing, should ISM receive notice of
              or become aware of any third party claim or assertion against ISM
              (or the IBM Related Companies) of ownership or of copyright or
              patent infringement or of infringement of any other intellectual
              property right pertaining to any aspect of the IBM-Made
              Modifications or the use thereof and provide a copy of any such
              claim or assertion (if the claim or assertion is provided in
              writing) or a description thereof (if made orally) and upon
              OptiMark's request, ISM shall provide reasonable responses to
              reasonable OptiMark inquiry concerning such claims or assertions
              and any risk of injunction as perceived by ISM.

       8.6    The provisions in sections 8.1 to 8.5 represent ISM's entire
              obligation to OptiMark regarding any claim for infringement,
              except as set forth in section 8.5.

       8.7    ISM has no obligation under this Agreement regarding any
              infringement claim based on the following:

              8.7.1  Any OPS Modifications other than IBM-Made Modifications, or
                     any use of the IBM-Made Modifications in the OPS Modified
                     Work which is outside the license or grants of the License
                     Agreement;

              8.7.2  The combination, operation or use of the IBM-Made
                     Modifications with any product, data, computer equipment or
                     software that ISM or an IBM

                                       5
<PAGE>   6

                     Related Company did not recommend, intend or provide and
                     which infringement claim would not have been made out by
                     the use of the IBM-Made Modifications with any product,
                     data, computer equipment or communication software that ISM
                     or an IBM Related Company did or does recommend, intend or
                     provide; or

              8.7.3  The combination, operation or use of the IBM-Made
                     Modifications in the OPS Modified Work with any other
                     software used by OptiMark for trade processing, trade
                     matching and strategizing functions which ISM or the IBM
                     Related Companies do not recommend, intend or provide and
                     which infringement claim would not have been made out by
                     the use of the IBM-Made Modifications with software which
                     ISM or the IBM Related Companies did or do recommend,
                     intend or provide.

9.0    OPTIMARK'S INDEMNITY

       9.1    OptiMark will indemnify and save harmless ISM, the IBM Related
              Companies, their officers, directors, employees and agents
              (collectively and individually called the "ISM Indemnitees") from
              and against any and all liabilities, damages, costs or expenses
              awarded against or incurred or suffered by them or any of them
              (including, without limitation, reasonable legal fees incurred by
              them or any of them) arising out of any claim against them or any
              of them by a Customer or any subcontractor to OptiMark made in
              connection with this Agreement or the Services.

       9.2    OptiMark will assume, at its own cost, the defense or settlement
              of any claim in respect of which OptiMark is responsible to
              indemnify the ISM Indemnitees under section 9.1, and ISM will
              cooperate with OptiMark in connection therewith; except that with
              respect to settlements entered into by OptiMark (a) the consent of
              ISM will be required if the settlement provides for equitable
              relief against an ISM Indemnitee; and (b) OptiMark will obtain the
              release of ISM and any ISM Indemnitee. OptiMark will: (i) permit
              ISM to participate in the settlement or defense of the claim
              through counsel chosen by ISM; and (ii) promptly reimburse ISM and
              the ISM Indenmitees for the full amount of any loss resulting from
              any claim and all related expenses incurred by the ISM
              Indemnitees. In the event that OptiMark fails to assume the
              defense or settlement of any claim, ISM shall have the right, but
              not the obligation, to contest, settle or compromise the claim in
              the exercise of its reasonable judgement at the expense of
              OptiMark.

              from this Agreement or will be severed with respect to such
              transaction or person only, and the remainder of the Agreement
              will continue in full force and effect.

       13.4   Any waiver by either party of any obligation under this Agreement
              must be in writing and will not be considered to be a waiver of
              any other breach of the same obligation.

       13.5   Upon termination of this Agreement, all accrued obligations or
              liabilities and the provisions which by their nature are intended
              to endure beyond such termination will remain in effect.

       13.6   No action regardless of form may be brought by either party

              prior written consent of the other party.

1      PURPOSE

The purpose of this document is to describe in detail the application support
services ("Services") required for the Order Profile System (OPS) application
component of the OptiMark Trading System (OTS) of OptiMark Technologies
Incorporated (OTI), which will be executed by ISM Information Systems Management
Corporation (ISM), specifically the Professional Services, Securities Industry
Services (ISM).

2      BACKGROUND

The application software Order Profile System (OPS Application), provided by
ISM, represents one component of the overall OTS being operated by OTI. From an
application software view, OTS consists of eight (8) major application
components: Graphical User Interface (GUI), Institutional Server (I/S),
Distribution Server (D/S), Order Profile System (OPS), Matching Engine Complex
(MEC), Gateway Server, Pacific Stock Exchange application (PCX) and Audit
Server.

The major purpose of the OPS Application component is to receive orders,
maintain the order book of record, schedule matching cycles,
receive/log/broadcast executions from the MEC, and broadcast market information
to the external users of OTS. In order to provide this functionality, it is
necessary for the OPS to connect to several of the other application components
including D/S, Pacific Stock Exchange (PCX), Gateway Servers and the MEC.

OPTIMARK TRADING SYSTEM ARCHITECTURE

            [GRAPHIC DESCRIBING OPTIMARK TRADING SYSTEM ARCHITECTURE]

The implementation of OTS has been completed and this new technology was
launched into production for the securities industry on January 28, 1999. Now
that OTS is in production, it is necessary for the formalization of production
maintenance for the overall application.

3           OVERVIEW

The maintenance of the OPS Application will involve a complex set of services
that are described in this document. The relationships between the different
services and their corresponding dependencies will also be described. The
Services being implemented include the following:

-           production support,
-           change management,
-           modifications and enhancements,
-           release management,
-           operations support,
-           education, and
-           training.

These Services need to be performed in varying degrees depending on the type of
application environment they are being performed in. An application environment
is the physical location on a unit of computer hardware in which the OPS
Application resides and operates. There are currently nine OPS Application
environments that can be categorized into one of following four environment
types:

-           Production environment,
-           Integration Test environment,
-           Quality Engineering environment, and
-           Development environment.

The level of skills required by the ISM team to perform the Services is very
high and requires in-depth knowledge of the OPS Application as well as the
relation to each of the other seven (7) OTS application components. During the
first twelve months of the Agreement ISM will be providing the majority of the
Services required for OPS Application maintenance. Over the lifetime of the
Agreement, 24 months, ISM will begin transitioning the maintenance
responsibilities to OTI. ISM and OTI will mutually agree on the transition plan,
schedule and evolution before the end of December 31, 1999.

The Services performed on the Production environment require a high level of
skill and intimate knowledge of the OPS Application. Therefore, the Production
environment will, initially, be supported primarily by ISM staff who possess the
in-depth knowledge of the OPS Application. The support for the Integration Test
environment requires a level similar to the Production environment; the main
difference being the time frame for which a problem can be resolved. Obviously,
problems encountered in the Integration Test environment will not have to be
resolved with the same urgency. ISM staff will remain actively involved in the
Integration Test environment, for the duration of this Agreement, to facilitate
a smooth migration of the OPS Application from the Integration Test environment
to the Production environment. For Quality Engineering and Development
environments, ISM will perform a larger role during the intitial 12 months of
this Agreement followed by the beginning or the transitioning of tasks to OTI.

The parties agree that the following matrix depicts the view of the
responsibilities of each party relative to the Services as of the Effective
Date. Over the term of this Agreement it is the

                                       22

intention of the parties that the dependency on ISM resources is to be reduced
so that ISM is only involved in the support of the Production and Integration
Test environments while OTI assumes overall responsibilities for the other
environments.

4      DOCUMENT FORMAT

In order to simplify the documented description of the Services that are
required within each of the application environments, the document has been
structured to describe the full set of Services required in the Production
environment and then each subsequent environment is described using this same
format. A matrix of each Service component is mapped against each of the nine
(9) environments depicting whether OTI or ISM is performing the Service.
