                        TECHNICAL SERVICES SCOPE OF WORK

The Services as generally described in Article 1 - SCOPE, are more definitively
described as stated below:

Cayenta.com shall provide SEMPRA ENERGY with consulting and professional
services support on a Time and Expense basis that includes but is not limited to
the following.

EFX APPLICATIONS PROJECTS

OVERVIEW

CAYENTA.COM will deliver time and materials consulting and contract services
in support of the enablement of nine strategic business applications to
operate within the EFX FRAMEWORK and also to deliver added business function.
The nine applications to be enabled and enhanced are CIS, CISCO, Gas Select,
GIR, Gas Select, OMS-A, OMS-B, MCS, Phoenix and Web Portal Enablement-SAP.
Cayenta.com will support eight related projects, which will deliver the
business enhancements and EFX integration.

The EFX FRAMEWORK is SEMPRA ENERGY'S strategic direction for delivering and
managing superior (web technology based) business applications in a
competitive market. The EFX Framework will enable delivery of new and
enhanced applications more rapidly, with higher quality and at lower cost
than can be delivered by conventional development methods.

The projects will deliver all created services and facilities in accordance
with Sempra Energy's EFX framework. All services will be designed such that
the resulting software components can be factored into Sempra Energy's
Business Services and Common Horizontal Facilities libraries. All web
components will make use of EFX web services to develop any and all web
client solutions.

EFX CIS ENABLEMENT

The CIS application provides customer care and billing functions for all
SoCal Gas core customers and partial customer management services for the
Phoenix non-core system.

This project will support the CIS application team in creating application
components that assist the CIS team to migrate the application away from OS/2
and Smalltalk. In addition, this project will deliver new component services
that help the CIS team extend their WEB-based client and add additional
e-commerce facilities as well as develop new CIS-specific integration
services and components

<PAGE>

mandated by GIR.

Specific services to be delivered include a java and CORBA-based CICS access
service packaged to meet specific CIS needs. Smalltalk process management
services will also be provided as well as Smalltalk CORBA interface to EFX to
enable the eventual migration of the CIS system to a physical 3-tier
implementation. The project will assist the CIS development team to integrate
GIR project requirements as new EFX components.

EFX CISCO ENABLEMENT

The CISCO application provides customer care and billing functions for all SDG&E
customers.

The purpose of this project is to provide bolt-on components and services that
make the CISCO application easier to interface with other applications, provide
enhanced services in support of Electric Industry Restructuring (EIR) and Gas
Industry Restructuring (GIR), and enable web-based customer access to billing
information.

EFX GIR INTEGRATION

Gas Industry Restructuring (GIR) is a PUC-initiated activity underway in
California to provide increased competition in the California natural gas
marketplace. One of the key impacts of this initiative is on Utility
Distribution Company (UDC) information technology systems that will require
modification to meet new regulator specified functional requirements. A key
aspect of these changes will be a requirement to provide expanded interfaces and
e-commerce facilities that link UDC's with their trading partners (e.g.,
retailers, shippers).

The purpose of this project is to provide a common platform that can be shared
by both SoCal Gas and SDG&E to provide e-commerce, trading partner integration,
and common GIR-mandated bolt-on services that can be utilized by both company's
application suite to meet the needs of deregulation. This project will develop a
common set of GIR-specific integration services and bolt-on functional
components that can be shared by both SoCal Gas and SDG&E.

EFX GAS SELECT DEVELOPMENT

The Gas Select application provides an on-line order entry system for SoCal Gas
non-core commercial customers.

The application, as part of the overall GIR process and in response to
competitive pressures needs to be redeveloped as a web-based portal solution.
The development of the application as a web-based solution will enable the Gas
Select to not only provide enhanced functionality, but will also provide lowered
support and maintenance costs on the part of the Gas Company as the system's
client will eliminate most client support issues. The purpose of this project
will be to provide the core web services and management facilities to host the
Gas Select application as an Internet portal. A key expected requirement is the
need to package commerce grade security with application to support secure
end-user access over

<PAGE>

the web.

EFX OMS INTEGRATION PLATFORM DEVELOPMENT - A

Outage Management Systems (OMS) are mission-critical applications that are
required to detect system outages and manage the recovery of service to Sempra
Energy customers. SDG&E has initiated a new project to replace its current
system with a new application platform. To operate, this new system will be
required to integrate key utility systems including GIS, SCADA, service order
dispatch, work force management, and customer information systems with the core
outage management system functionality. As a mission-critical system, it is also
necessary that the OMS application be highly-available to its users and be able
to sustain operations in a 7X24 environment and under degraded modes of
operation including application server failures.

The purpose of this project is to establish the necessary integration
infrastructure to host the OMS system including application integration, system
monitoring, and failure recovery services. This project will result in the
development and deployment of a system integration framework and management
environment for the OMS. Key services to be provided are application specific
proxies that will enable communication between all OMS II system components.
Specific proxy objects needing development for the OMS II include
representations of the CISCO, SORT, GFMS, and SCADA applications. A key focus
will be to provide facilities and services for enabling the OMS II system to
remain in operation in response to failures in feeder application systems as
well as support the dynamic redeployment of the OMS II application components in
response to system failures.

                       TECHNICAL SERVICES SCOPE OF WORK

The Services as generally described in Article 1 - SCOPE, are more definitively
described as stated below:

Cayenta.com shall provide SEMPRA ENERGY with consulting and professional
services support on a Time and Expense basis that includes but is not limited
to the following.

EFX INFRASTRUCTURE DEVELOPMENT PROJECTS

OVERVIEW

CAYENTA.COM will deliver time and materials consulting and contract services
in support of seven EFX FRAMEWORK related projects.

The EFX FRAMEWORK is SEMPRA ENERGY'S strategic direction for delivering and
managing superior (web technology based) business applications in a
competitive market. The EFX Framework will enable delivery of new and
enhanced applications more rapidly, with higher quality and at lower cost
than can be delivered by conventional development methods.

The projects will continue the development of new and improved EFX services
that can be leveraged by the IT community across all Sempra Energy companies,
create best practices for EFX development that can deployed as an integral
part of an overall FFX-based project delivery, develop new and improved EFX
Enterprise Infrastructure that can be leveraged by the IT community across
all Sempra Energy companies, provide specific courseware to train Sempra
Energy staff in the utilization of EFX, create the necessary tools and
supporting processes for administering within and across Sempra Energy
companies, create best practices for EFX development that can deployed as
an integral part of an overall EFX-based project delivery and to ensure that
EFX software is adapted, when necessary, to be compatible with core
technology selections being made by the corporation. The seven projects
included are EFX Core Services, EFX Design Center, EFX Enterprise
Infrastructure, EFX Rollout, EFX Operations 2000, EFX Process 2000 and EFX
Technology 2000. Brief descriptions are provided below.

EFX CORE SERVICES

EFX has been created by Sempra Energy to provide a common platform for
developing and integrating software in a single, high quality, supportable
environment. The purpose of this

<PAGE>

activity is to continue the development of new and improved EFX services that
can be leveraged by the IT community across all Sempra Energy companies.

This activity will result in the development of EFX 3.0. EFX 3.0 will be
based on the existing EFX 2.0 release but include newly developed components
and services. In addition to new development, a major aspect of this task
will be to factor and repackage code submissions made by Sempra Energy
development teams into sharable infrastructure services and components. New
development will focus on blending high quality, low cost component-based
products with standards compliant interfaces to develop a sharable set of
framework services that can be affordably deployed through out all Sempra
Energy company's and Soliance Network customers. Expected activities to be
conducted as part of EFX 3.0 include the integration of workflow services,
business object persistence services, and web portal and commerce facilities.
Additional areas will be added in response to application and integration
project demands. Finally, EFX 3.0 will be supported with user documentation
and examples.

EFX DESIGN CENTER DEVELOPMENT

Effective systems engineering processes are critical to the quality and
on-time delivery of software and system projects. Sempra Energy IT leadership
has recognized this fact and has made a significant commitment to institute
processes to manage and guide systems development and support. The purpose of
this task is to create best practices for EFX development that can
deployed as an integral part of an overall EFX-based project delivery.

This activity will adapt and extend the previously developed SDCDC-developed
Strategic Needs Assessment Process (SNAP) with extensions to support the
estimation, delivery, and ongoing operational support for EFX projects. Any
and all development processes will be based on leading industry solutions and
best practices and support a rapid iterative model of development and support
to ensure that any major project release is held to less than [...***...].
Further, it is expected that this activity will be conducted in close
cooperation with the Sempra Energy IT Quality Directory to ensure compliance
with any existing Sempra Energy systems engineering best practices.

EFX ENTERPRISE INFRASTRUCTURE II

EFX has been created by Sempra Energy to provide a common platform for
developing and integrating software in a single, high quality, supportable
environment. The purpose of this activity is to develop new and improved EFX
Enterprise Infrastructure that can be leveraged by the IT community across
all Sempra Energy companies.

This activity will result in the development of Enterprise Infrastructure
Applications such as an Enterprise Business Repository, LDAP Enterprise
Directory Services, Enterprise FTP Services, Enterprise FAX Services, and
Enterprise EDI services. This project is intended to increase the robustness
of the EFX infrastructure by both meeting new application requirements as
sharable framework services and harvesting existing applications for new
component services.

EFX ROLLOUT

EFX has been created by Sempra Energy to provide a common platform for
developing and integrating software in a single, high quality, supportable
environment. The purpose of this activity is to provide specific courseware
to train Sempra Energy staff in the utilization of EFX.

This activity will result in the development of a comprehensive set of
training courseware for EFX that can be provided to Sempra Energy's IT
community. The following courses are to be created as part of this activity:

- EFX for Java Programmers
- EFX for Visual Basic Programmers
- EFX for PowerBuilder Programmers
- EFX for System Administrators and Operators

This project is necessary to create the curriculum and courseware required to
train Sempra Energy IT staff to effectively utilize EFX and EFX services.
These classes are absolutely necessary to ensure the success of the EFX roll
out across Sempra Energy.

EFX OPERATIONS 2000

EFX has been created by Sempra Energy to provide a common platform for
developing and integrating software in a single, high quality, supportable
environment. Applications developed utilizing EFX are entering production and
will increasingly require support by Sempra Energy Operations staff. The
purpose of this activity is to create the necessary tools and supporting
processes for administering within and across Sempra Energy companies.

This activity will focus on the creation of EFX management tools and
processes that can be hosted in the current Sempra Energy data center(s).
These tools will be capable of administering and monitoring the EFX
environment and the applications under the control of EFX. A major focus will
be to integrate EFX with Sempra Energy operations management tools to ease
the overall training and support burden on data center staff. Special
attention will be placed on the coordination of software installation,
backup, job scheduling, and runtime tuning of system performance. This task
will also provide full documentation and processes for using all developed
operations tools. This project will be required to enable the full management
of EFX applications by the Sempra Energy Rancho Bernardo data center and
other operational support centers in a standardized manner and at reasonable
cost. It is expected that this activity will enable operations to provide
first and partial second level support for new and existing applications that
make use of EFX management services rather than by applications development
staff.

EFX PROCESS 2000

Effective systems engineering processes are critical to the quality and
on-time delivery of software and system projects. Sempra Energy IT leadership
has recognized this fact and has made a significant commitment to institute
processes to manage and guide systems development and support. These systems
engineering efforts have focussed principally on working with existing
development teams and platforms responsible for maintaining Sempra Energy's
current software inventory. The purpose of this task is to create best
practices for EFX development that can deployed as an integral part of an
overall EFX-based project delivery.

This activity will adapt and extend the previously developed SDCDC-developed
Strategic Needs Assessment Process (SNAP) with extensions to support the
estimation, delivery, and ongoing operational support for EFX projects. Any
and all development processes will be based on leading industry solutions and
best practices and support a rapid iterative model of development and support
to ensure that any major project release is held to less than [...***...].
Further, it is expected that this activity will be conducted in close
cooperation with the Sempra Energy IT Quality Directory to ensure compliance
with any existing Sempra Energy systems engineering best practices.

This project is to create the project management and organizational templates
needed to complement EFX-based projects and to assist Sempra Energy IT and
Soliance Networks in competing against leading systems integrators.

EFX TECHNOLOGY 2000

EFX has been created by Sempra Energy to provide a common platform for
developing and integrating software in a single, high quality, supportable
environment. The purpose of this activity is to ensure that EFX software is
adapted, when necessary, to be compatible with core technology selections
being made by the corporation.

This activity will result in the modification of existing and new Sempra
Energy technology components as they enter the corporate inventory. This
activity will focus principally on porting and adapting EFX to all Sempra
Energy operating systems (e.g., MVS) and system services (e.g., RACF
security). A key activity will be to ensure that the preliminary support for
clustering on Sun's Solaris operating system is extended and ported to the
Windows NT/2000 environment. Additional system ports planned as a part of
this activity include MVS, RedHat Linux, HP/UX, and AIX. These ports, with
the exception of Linux, are required to bring existing Sempra Energy
applications under EFX management control.

This project is required to ensure that EFX is compatible with the entire
Sempra Energy deployment environment and suite of system services. This
breadth of coverage will also assist Sempra Energy in adapting EFX to support
and manage applications resulting from corporate acquisitions or owned by
Soliance Network customers.
