of the "not to exceed project budget", an executive officer of Enova approves
in writing a revised not to exceed project budget" for the Services. No right
to exceed any deliverable budget or to exceed project budget" shall be
inferred from course of performance or course of dealing. The "not to exceed
budget" is based upon Contractor's two year cost estimate for the Services
specified in SCHEDULE A which is attached as SCHEDULE C - TASK COST
ESTIMATES. The TASK COST ESTIMATES do not impose any obligation on Enova to
use a minimum number of hours of Contractors Services and are not intended by
either party to be used as a performance standard, as a measure of damages or
as a basis for the calculation of any termination fees. The "not to exceed
budget" is not a budget for any deliverable and does not negate the
obligation to budget the individual deliverables.

      12.2 Contractor hereby agrees to accept as full compensation for
satisfactory performance of the Services as described in Article 1 and SCHEDULE
A, the compensation

from a third party who did not receive same, directly or indirectly, from Enova.
Contractor shall use the higher of the standard of care that Contractor uses to

prevent unauthorized use or disclosure of such Confidential Information.

      30.2 COURT OR ADMINISTRATIVE ORDER. Notwithstanding the provisions of
Section 30.1 above, Contractor and its employees, agents and representatives
("Representatives") may disclose any of the Confidential Information in the
event, but only to the extent, that, based upon advice of counsel, it is
required to do so by the disclosure requirements of any law, rule, or regulation
or any order, decree, subpoena or ruling or other similar process of any court,
governmental agency or governmental or regulatory authority. Prior to making or
permitting any of its Representatives to make such disclosure, Contractor shall

after the date of disclosure of such Confidential Information.

Contractor, Enova shall be entitled to seek an injunction preventing such
breach, without the necessity of proving damages or posting any bond. Any such

                                       FOR
                              CENTER OF EXCELLENCE

1. Strategic Architecture Refinement and Maintenance

      Transnational Partners II ("Contractor") and the Information Technology
      Services Department of Enova ("ITS") have completed a preliminary
      architecture specification for Enova's future information technology as
      set forth in the ITS Future State document dated October, 1996 attached
      hereto ("architecture specification"). This architecture specification is
      being used as a blue print for building the software infrastructure that
      is the heart of the Center of Excellence. This architecture specification,
      like software itself, must be updated regularly to provide Enova with a
      strategic direction that is relevant both to underlying business and
      technology directions. Contractor shall provide Enova ongoing advice and
      assistance in finalizing and updating, as necessary, the architecture
      specification.

2. Center of Excellence Staff

      2.1   Employees. The staff of the Center of Excellence will be composed of
            internal Enova employees and external contract support staff
            retained by Contractor. Enova business timelines make it imperative
            that selected employees and contractors possess the necessary
            technical skills and vision behind Center of Excellence projects.
            Enova expects that it will hire through its normal employment hiring
            channels any personnel that it will need to operate the Center of
            Excellence and to support business line product development.
            Contractor shall assist Enova in screening, conducting initial
            interviews and recommending persons to fill any Enova employee staff
            positions for the Center of Excellence. All Enova hiring decisions
            shall be made by Enova.

      2.2   Contract Personnel. Contractor, however, may retain contract support
            staff (as opposed to system integrators and other vendors who may
            provide services in connection with the projects) to fill positions
            that are expected to be temporary or be limited to the duration of
            the Contractor project to work under the direction of Contractor
            and, subject to the conditions specified below, may hire individual
            expert programmers to work on approved projects under the direction
            of Contractor. Contractor shall be responsible for entering into an
            appropriate confidentiality, work made for hire, and invention
            assignment agreements with each of its contract support staff and
            subcontractors in form and substance reasonably satisfactory to
            Enova and Enova shall be named a third party beneficiary of those
            agreements (such form to be prepared and approved prior to the
            execution of this Agreement). Contractor shall responsible for
            paying its contract support staff and any third party programmers or
            consultants that it directly retains, including any out-of


                                      A-1
<PAGE>

            pocket expenses or per diem allowances which are not reimbursable by
            Enova.

            Contractor acknowledges that it is not a general contractor under
            this Agreement and that Enova will generally procure third party
            software, including customized software, directly from vendors.
            However, Contractor has represented to Enova that it has contacts
            with individual expert computer programmers and integrators who work
            on projects throughout the country on a consulting basis and who may
            be willing to work as subcontractors on this project because of
            Contractors involvement. Subject to (a) Enova's written approval of
            (i) each specific project on which a subcontractor will work, (ii)
            unless the specific project requires fewer than eight man hours or
            unless otherwise waived in writing by the Enova Representative, the
            functionality specifications and performance requirements for each
            custom software or programming to be done by the subcontractor, and
            (iii), unless the specific project requires fewer than eight man
            hours, Enova and Contractor's agreement as to a fixed fee or time
            and materials arrangement with a budget and milestone and
            deliverables schedule for each such specific project and (b)
            Contractor's adherence to the software development terms and
            conditions set forth in this SCHEDULE - A, then Contractor may
            retain such consultants as a subcontractor and bill Enova for the
            services in accordance with the agreed upon fee arrangement and in
            accordance with the payment provisions of this Agreement.

3. Enova Enterprise Infrastructure Development

      3.1   GENERAL. Contractor shall provide lead direction, management and
            system engineering in the development of the following components of
            the Enova Enterprise Infrastructure as specified in the architecture
            specification approved by Enova: (i) enterprise network
            infrastructure, (ii) system security for the Center of Excellence,
            (iii) data and application services infrastructure for the Center of
            Excellence, (iv) world wide web infrastructure, (v) legacy systems
            data access and interface operability, (vi) desktop environment for
            the staff of the Center of Excellence, (vii) data repository for the
            Center of Excellence's access to enterprise wide data from separate
            existing and legacy systems, (viii) middleware layer of the
            infrastructure for the Center of Excellence, (ix) integrated system
            management environment for the maintenance and operation of an
            enterprise computing environment and (ix) repository of application
            software components and application software standards. Each of
            these items will be developed in accordance with the approved
            architecture specification.

      3.2   REQUIREMENTS

            3.2.1 Network Infrastructure.

                  (a)   prepare with Enova's input and submit for Enova's
                        written approval a detailed design specification for
                        each of the five networks specified in the architecture
                        specification (I.E. firewalls

            each deliverable.

      E.6   Unless the project requires fewer than eight man hours or unless
            Enova otherwise waives the term in writing, Enova and Contractor
            shall agree in writing upon an acceptance test procedure for the
            alpha, beta and final versions of each deliverable. During the
            agreed upon testing period for each version, Contractor and Enova
            shall jointly test the deliverable, in accordance with the agreed
            upon procedure, to verify if it meets the functionality
            specifications and performance requirements. Enova shall inform
            Contractor of any errors or deficiencies discovered during any of
            the test periods. Contractor shall promptly proceed to correct any
            errors or deficiencies.

      E.7   Contractor warrants that for a period of six months following
            Enova's written acceptance of the final version of a deliverable,
            any component of any such deliverable which has been provided by
            Contractor or any of its subcontractors will perform substantially
            in accordance with the functional

            specifications and performance requirements for such deliverable
            when properly installed and operated on the computer system for
            which the deliverable was designed; provided however, that such
            warranty by Contractor shall not extend to any component of any such
            deliverable which has been provided by Enova or any contractor of
            Enova. In addition, Contractor warrants that no deliverable will
            contain any "back door," "time bomb," "Trojan horse," "worm," "drop
            dead device", or "virus" as these terms are commonly used in the
            computer software industry), or other software routines or hardware
            components designed to permit unauthorized access, to disable or
            erase software, hardware, or data in a manner unauthorized by, and
            contrary to the intentions of, the user, or to perform any other
            similar unauthorized destructive type of functions. Contractor shall
            pass through to Enova any third party warranties on any software
            components

      E.8   Contractor does not warrant that the operation of the software
            deliverables will be error free or uninterrupted or that all defects
            in the software deliverables will be corrected; provided, however,
            that upon Enova's request, Contractor shall promptly correct
            significant defects or provide replacement services for any
            Significant Non-Conforming Services. Significant Non-conforming
            Services is defined as the failure of a deliverable product to
            perform substantially any of the functions specified in the
            functional specifications for such product or to meet substantially
            the performance requirements for such product. Contractor shall use
            best efforts to have any Significant Non-conforming Services or
            significant defects that cause disruption of critical business
            operations of the Center of Excellence corrected within 48 hours of
            the first report of such Significant Non-conforming Service or
            significant defect.

      E.9   The use of any deliverable by Enova shall not violate or infringe
            the rights of any third party.

      E.10  Each subcontractor shall maintain the same type of insurance in the
            same amounts as required of Contractor unless Enova waives in
            writing this requirement as to a particular subcontractor.

      E.11  The other terms and conditions of the Agreement shall apply,
            including, without limitation, Sections 8, 14, 15, 18, 19 and 22.

      E.12  No waiver of any term or condition for software deliverables shall
            constitute a waiver as to all such terms or conditions or as to such
            term or condition as applied to any other deliverable. The foregoing
            terms and conditions may not be modified by course of dealing,
            course of performance or trade usage and may only be modified in
            writing signed by both parties.

                              CENTER OF EXCELLENCE

9. CITO OPERATIONS AND SUPPORT

The Contractor shall assist the Enova Office of the Chief Information Technology
Officer ("CITO") to develop and implement information technology-related
policies and procedures for both the Center of Excellence and the new entity to
be created through the merger of Enova Corporation and Pacific Enterprises
("NewCo"). To fulfill this role, the Contractor will participate in relevant
CITO staff meetings and, to the extent requested by the CITO to create and
present position papers and other presentations. Also, to the extent requested
by the CITO, the Contractor shall provide business and technical expertise to
the CITO to identify and select strategic partners and technology.

10. NEW PROJECT DEVELOPMENT SUPPORT

10.1  GENERAL. Section 4 of the SCHEDULE A did not specify in detail a specific
      process by through which new business line development or other
      application program projects could be initiated. Subject to Enova
      approval, the Contractor will develop a procedure for the initiation of
      new projects in the COE, including the provision of senior-level technical
      and business process support for the projects. In addition to the items
      specified in Section 4, as part of this activity, Contractor will perform
      the Services specified in Section 10.2.

10.2  REQUIREMENTS

      a)    Work with Enova and technical project managers for the business
            initiating the project to develop project requirement
            specifications, project plans and budgets.

      b)    Develop top-level operational concepts for building and deploying
            new business support systems, subject to Enova's approval.

      c)    Conduct internal rapid implementation plan (RIP) workshops utilizing
            the COE design center.

      d)    Assist Enova and the technical project managers for the business
            initiating the project in the selection of project implementation
            support partners.

      e)    Assist Enova and the technical support managers for the business
            initiating the project in the selection of third party software
            development tools and applications

      f)    Assist NewCo project managers to understand and access the resources
            and services available within the COE.

11. COE DESIGN CENTER DEVELOPMENT

11.1  GENERAL. Successful utilization of software rapid application development
      (RAD) processes requires the development and usage of a formalized project
      implementation methodology. In addition, the methodology must be supported
      by an adequate physical infrastructure that facilitates, rather than
      hinders, the RAD process. Finally, trained facilitators are required to
      assist project teams in the development of requirements and design
      specifications that are adequate to meet the needs of software
      implementation teams.
<PAGE>

      The Contractor will develop, with the approval of Enova, a formal RAD
      process for application software development for the Design Center.
      Subject to Enova's budgetary considerations and approvals, this Design
      Center generally will contain the necessary physical, technical, and
      procedural infrastructure necessary to incubate and deliver application
      software projects in adherence with RAD project management and delivery
      principles. The Design Center will be located at Enova's Sorrento Mesa
      facility.

11.2  REQUIREMENTS

      a)    Develop RAD process templates for all project phases (requirements,
            design, implementation, stabilization, and production). These
            project templates will serve as a shared design and implementation
            template to be used across all NewCo projects.

      b)    Design a prototype Design Center. The design for the prototype
            Design Center will contain the necessary team rooms, break out work
            areas, implementation, support areas, and technical infrastructure
            (e.g., audio visual equipment) needed to support the RAD process.
            The design shall be subject to the CITO's input and prior approval
            and any tenant improvements, fixtures, furnishings, and equipment
            shall be procured through Enova's normal procurement channels and be
            subject to Enova's normal budget and approval processes.

      c)    Identify and recommend to Enova the software support systems needed
            to manage the RAD process, assist Enova in procuring through its
            normal procurement channels such software support systems, and
            integrate the software support systems. Anticipated support systems
            include design software systems (e.g., Rational Rose), project
            management software, and project action item and tracking databases.

      d)    Develop process manuals and training curriculum to support the
            Design Center. This process manuals and training materials will be
            used to mentor new staff in the COE RAD development methodology.
            These manuals and training information will be tailored to support
            the specific employment of COE design support systems and software
            implementation tools.

12. BUSINESS OBJECT DEVELOPMENT FRAMEWORK

12.1  GENERAL. The focus of this task is to create the necessary framework for
      expressing fine-grain business objects and components. The development of
      the business object framework complements the current COE enterprise
      framework task. In particular, the fine-grain business objects created
      utilizing the framework developed in this task will implement the behavior
      and processing of enterprise service objects. These fine-grain business
      objects are tailored to utilize specific implementation languages (i.e.,
      Java) and are instantiated as process local objects. The Contractor will
      create a framework so that it is completely compatible and operational
      with the existing Enova COE enterprise framework. The framework will be an
      integration of existing enterprise frameworks (e.g., Claremont Technology
      Group's Business Solution Framework) and technology platforms (e.g., Sun's
      Java Beans) rather than a proprietary framework developed from scratch.

12.2  REQUIREMENTS

      a)    Evaluate existing candidate technical solutions and products as a
            basis for creating the NewCo business object framework

      b)    Subject to Enova's input and approval, develop a requirement
            specification for the overall business object framework. A part of
            this requirement specification will be to determine the
            implementation languages and environments that must be addressed by
            the business object framework.

      c)    Subject to Enova's input and approval, develop design specification
            for the business object framework. Included in the design
            specification will be plans for integrating the


                                       A-2

<PAGE>

            business object framework with the existing COE enterprise component
            model and services.

      d)    Implement the business object framework. An aspect of this task will
            be to coordinate the delivery and integration of software developed
            by contracted third parties and product suppliers into the business
            object framework.

      e)    Iterate the development of the framework to meet new requirements
            resulting from the utilization of the business object framework by
            NewCo application project teams.

13. APPLICATION PROJECT SUPPORT

13.1  GENERAL. Upon the request of Enova, the Contractor shall provide
      architectural and programming assistance to application development
      efforts in NewCo that utilize the COE infrastructure and services. The
      Contractors role shall be limited to providing the technical integration
      and object modeling skills to utilize the COE infrastructure effectively,
      rather than providing general application development staff. As of the
      date of this Amendment, the projects covered by this task are Pacific
      Enterprises' Phoenix and Energy Pacific's Energy Delivery Management (EDM)
      system. Any future projects will be added through a new Scope of Work or
      other amendment to the Agreement.

13.2  REQUIREMENTS

      a)    Provide projects with COE enterprise modeling and technical
            implementation support.

      b)    Assist the project in implementing enterprise interfaces to other
            NewCo systems utilizing the COE integration framework.

      c)    Assist the project team in developing business object services
            utilizing the COE framework.

      d)    Assist the project management team in negotiations with the
            implementation partners and vendors.

      e)    Assist project managers to ensure that contracted delivery partners
            are meeting overall NewCo objectives.

14. NEWCO SYSTEM CONSOLIDATION

14.1  GENERAL. The information technology ("IT") merger team is in the planning
      phase for consolidating the current set of applications fielded by both
      Enova and Pacific Enterprises into a single, unified suite. The Contractor
      will provide the system consolidation team with both technical
      infrastructure and enterprise object modeling expertise to plan and
      implement the integration of the NewCo application suite. The Contractor
      expertise will be focused on leveraging the existing COE infrastructure to
      create an integration solution based on sharable business objects rather
      on a point solution which link specific applications using pair-wise
      interfaces.

14.2  REQUIREMENTS

      a)    Work with the IT system consolidation program manager to develop
            application consolidation strategies.

      b)    Assist the system consolidation program in selecting application
            integration technology. A part of this selection process will be to
            assess the suitability of the existing and planned COE enterprise
            infrastructure to support application consolidation.

      c)    Subject to system consolidation team input and approval, design and
            develop standard interface solutions that can be shared across
            application interface development teams. It is expected that this
            activity will result in the creation of a set of foundation
            interface classes and techniques that will form the basis of the
            general integration solution.


                                      A-3
<PAGE>

            Standard interface forms will consider real-time, batch, mainframe,
            and client-server interfaces in addition to any relevant permutation
            of these factors.

      d)    Assist the system consolidation team in expressing the consolidate
            application suite as business objects.

      e)    Assist the application consolidation team in developing concrete
            interfaces that link existing application processing and interface
            requirements to the common enterprise object model.

15. OTHER PROJECTS

      a)    To the extent that Enova or Pacific Enterprises' requests that the
            Contractor work on other significant projects that are not covered
            by the existing scope of services, including, without limitation,
            due diligence for possible acquisitions, the scope of Services and
            the budget for such Services shall be set worth in either a new
            Scope of Work or an amendment to this Agreement.
