                                    RECITALS

         WHEREAS, Predictive wishes from time to time to perform Enterprise
Management services for Bear Stearns and Bear Stearns wishes to consider
engaging Predictive to perform such services (an "Assignment").

         WHEREAS, in the interest of streamlining the startup phase of any such
Assignment, Bear Stearns and Predictive wish to agree in advance as to certain
terms and conditions under which such services may be rendered;

         THEREFORE, for good and valuable consideration given pursuant to the
terms, conditions and covenants contained herein, Bear Stearns and Predictive
hereby agree as follows:

SECTION 1:        STATEMENT OF WORK, SERVICES AND DELIVERABLES

1.1.     Each Assignment will be commenced by a Statement of Work executed by
         both Bear Stearns and Predictive (a "Statement of Work") referencing
         this Agreement, and setting forth: (i) the deliverables to be produced
         (the "Deliverables") and/or the other services to be performed (the
         "Services"); (ii) the schedule for delivery of such Deliverables,
         performance of such Services, and the date of completion of
         Predictive's performance under the Statement of Work ("Completion
         Date"); (iii) the agreed fees and costs consistent with this Agreement
         for such Services and Deliverables ("Statement of Work Fees"); (iv) the
         schedule for payment of such fees and costs ("Payment Schedule"); and
         (v) the acceptance criteria against which the completeness of
         deliverables will be measured ("Acceptance Criteria"). Notwithstanding
         the foregoing, whether or not such Statement of Work sets forth the
         items set forth in (i) through (v) above or refers to this Agreement,
         the terms, conditions and provisions of this Agreement shall apply to
         such Assignment and shall be automatically incorporated into such
         Statement of Work, regardless of the terms discussed with any third
         party.

1.2.     As and when required by and Statement of Work and this Agreement,
         Predictive shall perform for Bear Stearns the Services described in the
         Statement of Work and shall deliver to Bear Stearns the Deliverables
         described in the Statement of Work.

1.3.     Notwithstanding the generality of Section 1.2., above and in addition
         thereto, at the conclusion of each month during the term of each
         Statement of Work, Predictive shall deliver to Bear Stearns all
         Deliverables (including drafts and other work in progress) produced by
         Predictive in the performance of the Statement of Work over the course
         of that month.

1.4.     Predictive warrants that it has or will provide the resources and
         personnel necessary to carry out its work under each Statement of Work
         and will use its best efforts to perform all work required under this
         Agreement and each Statement of Work in a timely, skillful, and
         efficient manner. Predictive shall not be responsible for any delay in
         the performance of Services due to causes beyond reasonable control of
         Predictive.

1.5.     After completion of each milestone of the Statement of Work against
         which a payment in the Payment Schedule is tied, (other than
         obligations intended to survive acceptance by Bear Stearns), Predictive
         will notify Bear Stearns in writing that Predictive has completed its
         performance, that the Services are fully implemented, that the
         Deliverables are fully implemented, and that Predictive's testing is
         completed. Bear Stearns, with the cooperation and assistance of
         Predictive, shall then be entitled to conduct a


         comprehensive, integrated acceptance test of the Acceptance Criteria on
         all the Services and Deliverables ("Acceptance Test"), and, if Bear
         Stearns reasonably determines that any material part of the Acceptance
         Criteria are not met during the Acceptance Test, to reject such
         Services and/or Deliverables by notifying Predictive in writing.
         "Acceptance" shall mean the receipt by Predictive of written
         notification from Bear Stearns that the Acceptance Test on the Services
         and Deliverables has been successfully completed. Any rejection shall
         state specifically the manner in which the Services and Deliverables
         are defective. In the event of rejection, Predictive shall correct any
         deficiencies and shall resubmit such Services and Deliverables for
         further Acceptance Testing in accordance with this paragraph. Bear
         Stearns shall not be invoiced for more than 80% of the aggregate amount
         due for any Services or Deliverables until such Services and
         Deliverables satisfy the Acceptance Test and are accepted by Bear
         Stearns pursuant to this Section 1.5.

SECTION 2:        PROPRIETARY RIGHTS IN DELIVERABLES, ETC.

2.1      Predictive agrees that (i) any and all Deliverables, (ii) any and all
         original other works of authorship, including, but not limited to all,

         compilations which may be created, compiled or produced by Predictive
         or any of its subcontractors, consultants or employees in the course of
         performing Services or producing Deliverables for Bear Stearns (along
         with the items described in (i) above, collectively, "Works of
         Authorship"), and (iii) any and all copyrights and other proprietary
         rights and all foreign and domestic, registered and unregistered,
         copyrights, applications for registrations therefor and other
         proprietary rights related to any Works of Authorship (collectively,
         "Copyrights"), shall be deemed to be works made for hire for and the
         exclusive property of Bear Stearns. Except to the extent specifically
         agreed in the Statement of Work, to the extent that Predictive has or
         obtains any right, title or interest in or to any Work of Authorship of
         Copyright, Predictive hereby assigns and agrees to assign to Bear
         Stearns all of such right, title and interest therein and thereto, and
         to the extent that any employee, agent or sub-contractor of Predictive
         has or obtains any right, title or interest in or to any Work of
         Authorship or Copyright, Predictive shall cause such employee, agent or
         sub-contractor to assign to Bear Stearns all of such right, title and
         interest therein and thereto.

2.2.     To the extent that any Deliverables or Services embody, contain or

         developments, improvements, techniques or expertise that are known by
         Predictive prior to Predictive's work for Bear Stearns or is developed
         by Predictive during the course of Predictive's work for Bear Stearns
         (collectively "Know-How") of Predictive, Predictive shall retain
         ownership of such Know-How, provided that Bear Stearns shall have the
         full, unrestricted and non-exclusive right to use, disclose, prepare
         works of authorship based upon any Know-How embodied by, contained in
         or disclosed by the Deliverables of Services and to copy, display and
         distribute any such works of authorship.

2.3.     Nothing herein shall prevent Predictive from providing services
         substantially similar to those contemplated herein, whether for a
         competitor of Bear Stearns or otherwise, and the parties expressly
         agree that in providing such services, or in developing its general,
         commercially available software products, Predictive may directly or
         indirectly utilize residual know-how in its area of expertise not
         specific to Bear Stearns resulting from the performance of the services
         contemplated herein.

2.4.     Upon the request of Bear Stearns, Predictive shall at Bear Stearns'
         reasonable out-of-pocket cost and expense do all acts and things,
         including, but not limited to, making and executing documents,
         applications, deeds, license agreements, assignments, transfers,
         conveyances, powers of attorney and instruments, using its best efforts
         to obtain the cooperation of and bringing claims and actions against
         its employees, ex-employees, agents, ex-agents and independent
         contractors and giving information and testimony, in each case,
         requested at any time and from time to time by Bear Stearns, in its
         good faith discretion, to vest, secure, defend, protect and/or evidence
         the right, title and ownership of Bear Stearns in and to any and all
         Works of Authorship and Copyrights. Predictive hereby appoints Bear
         Stearns and is successors and assigns as Predictive's attorney-in-fact,
         with full power of substitution, in the name and stead of Predictive or
         Bear Stearns, for the benefit of Bear Stearns and its successors and
         assigns, to from time to time do any and all such acts and things which
         Predictive is obligated to do under his paragraph. Predictive declares
         that the appointment made and the powers granted hereby are coupled
         with an interest and are irrevocable.

         order, Predictive either:

         (a)      obtains promptly for Bear Stearns the right to continue to use
                  the Deliverables which are the subject of the claim of
                  infringement without additional cost to Bear Stearns, or

         (b)      provides without cost to Bear Stearns an equally satisfactory
                  substitute Deliverables which achieve the same objectives as
                  the Deliverables which are the subject of the claim of
                  infringement, is equally practicable and functional and does
                  not infringe any copyright, patent, trade secret or other form
                  of proprietary or intellectual property rights of third

SECTION 10:       TERMINATION/BANKRUPTCY

10.1     Termination For Convenience By Bear Stearns. Bear Stearns may terminate
         this Agreement or a particular Statement of Work by giving thirty (30)
         days advance written notice to Predictive. Bear Stearns shall then pay
         within (30) days all unpaid amounts that have been incurred as of the
         date of termination plus a termination charge equal to thirty percent
         (30%) of the total remaining fees that would have been due under the
         terminated Statement(s) of Work, if the remainder of the Services
         described therein had been fully performed. The remainder balance shall
         be computed by subtracting the value of paid invoices from the total
         value of the Services under the terminated Statement(s) of Work. The
         parties agree that such termination charge shall constitute
         consideration for Predictive's time, effort and expense in preparing to
         perform its obligations, hereunder, as actual damages are difficult to
         ascertain. Predictive shall promptly deliver to Bear Stearns all
         Deliverables performed for and prepaid by Bear Stearns prior to the
         termination relating to such Statement of Work.

10.2     Termination For Breach by Bear Stearns. If Bear Stearns fails to pay
         any outstanding charges within forty-five (45) days after receipt of
         written notice of delinquency, or if Bear Stearns fails to perform or
         observe any other material term or condition of this Agreement for
         forty-five (45) days after receipt of written notice from Predictive of
         such failure, Bear Stearns shall be in default and Predictive may,
         without prejudice to any other right or remedy, suspend performance
         under, or terminate in its entirety, or in relation to a particular
         Statement of Work. Any unpaid charges or other obligations accrued to
         such termination shall survive termination of this Agreement or
         Statement of Work, as applicable.

10.3     Termination For Breach by Predictive. If Predictive fails to perform or
         observe any other material term or condition of this Agreement and/or
         Statement(s) of Work for forty-five (45) days after Predictive's
         receipt of written notice from Bear Stearns of such failure and has not
         commenced performance or observance of such material term or condition
         within such 45-day period, Bear Stearns shall have the option of
         immediately terminating the Agreement and/or Statement of Work involved
         in whole or in part, without further obligation including any
         additional payments, liability or penalty of any kind.

10.4     If Predictive becomes the subject of a case commenced under Title 11 of
         the United States Code (the "Bankruptcy Code") and Predictive, as
         debtor-in-possession, or a trustee appointed for Predictive ("Trustee")
         decides to reject this Agreement and/or any Statement of Work pursuant
         to Section 365(n) of the Bankruptcy Code, then Bear Stearns, in
         addition to all rights conferred by the Bankruptcy Code and other
         applicable law, shall have the right to treat this Agreement and/or
         such Statement of Work as terminated or to retain its rights
         thereunder. If Bear Stearns decides to retain its rights under this
         Agreement and/or Statement of Work, as the case may be, then (i) on
         written request of Bear Stearns, Predictive or the Trustee shall
         provide Bear Stearns with any and all information, Deliverables and any
         other Works of Authorship held by the Trustee, Escrow Agent or
         Predictive; and (ii) Predictive or the Trustee shall not interfere with
         the rights of Bear Stearns pursuant to this Agreement including, but
         not limited to the right to obtain any information pertaining to the
         foregoing from any other entity or individual, including employees,
         consultants and former employees and consultants of Predictive.
         Predictive acknowledges and consents that the automatic stay imposed by
         Section 362 of the Bankruptcy Code shall be automatically lifted,
         modified and/or vacated to allow Bear Stearns to realize any and all of



                                       6


         its rights herein. The provisions of this paragraph shall also apply in
         the event that Predictive or the Trustee has not rejected this
         Agreement or any Statement of Work. The parties hereby agree and affirm
         that the payments already paid by Bear Stearns as of the date of a
         rejection under the Bankruptcy Code, as described in the first sentence
         hereof, are full consideration for Predictive's obligation and
         undertakings under this Agreement and all applicable Statements of
         Work. These payments shall not be deemed to be royalty payments for the
         purpose of Section 365(n) of the Bankruptcy Code and if Predictive or
         the Trustee rejects this Agreement or any Statement of Work and Bear
         Stearns decides to retain its rights thereunder, Bear Stearns shall be
         relieved from its obligation to make such payments.

10.3.    Notwithstanding anything set forth in this Agreement, the assignments
         made and licenses granted in this Agreement shall survive the
         expiration or termination of the Agreement, regardless of the cause.

SECTION 11:       MISCELLANEOUS

11.1.    If any provision of this Agreement is declared or found to be invalid,
         illegal, unenforceable or void, then both parties shall be relieved of
         all obligations arising under such provision, but only to the extent
         that such provision is invalid, illegal, unenforceable or void, it
         being the intent and agreement of the parties that this Agreement shall
         be deemed amended by modifying such provision to the extent necessary
         to make it valid, legal and enforceable while preserving its intent or,
         if that is not possible, by substituting therefor another provision
         that is valid, legal and enforceable and achieves the same objective.
         Each party agrees that it will perform its obligations hereunder in
         accordance with all applicable laws, rules and regulations now or
         hereafter in effect.

11.2.    Headings are for reference purposes only.

11.3     Any notices required or permitted to be sent hereunder shall be served
         personally or by registered or certified mail, return receipt
         requested, reputable overnight delivery services such as Federal
         Express, Airborne Express or DHL, or by facsimile with confirmation of
         receipt; to the addresses listed above.

11.4.    This Agreement shall be interpreted and construed in accordance with
         the Copyright laws of the United States and the internal law of State
         of New York, without regard to the conflicts of law principles thereof,
         and any action brought in relation to this Agreement shall be brought
         in a Federal or state court in the City of New York and Licensee and
         Licensor hereby irrevocably consent to the jurisdiction of such Courts,
         and both parties hereby waiving any claim or defense that such forum is
         not convenient or proper. Each party hereby consents to service of
         process by any means authorized by New York law (other than by
         publication). Each party waives any right to trial by jury with respect
         to any dispute, suit, action or proceeding arising out of or relating
         to this Agreement or otherwise relating to the relationship of the
         parties, whether in contract, tort or otherwise.

11.5.    This Agreement may not be modified or altered except by a written
         instrument executed by both parties. The failure of either party to
         exercise in any respect any right provided for herein shall not be
         deemed a waiver of any rights. This Agreement, together with each
         Statement of Work hereunder, constitutes the entire agreement between
         the parties with respect to the subject matter hereof and supersedes
         and merges all prior proposals, understandings and all other
         agreements, oral and written between the parties relating to such
         subject matter. The rights and remedies of Bear Stearns under this
         Agreement and any Statement of Work are cumulative.

11.6.    Neither party may assign this Agreement or any Statement of Work or
         delegate any obligations hereunder or thereunder, except that
         Predictive may sub-contract some or all of its performance under the
         Agreement only with the written consent of Bear Stearns, which shall
         not be unreasonably withheld; provided, however, that all obligations
         of Predictive under this Agreement shall apply fully to any such
         sub-contractor as if it were "Predictive" under this Agreement and
         Predictive shall remain fully liable for the performance of such
         assignee or sub-contractor hereunder; and Bear Stearns may from time to
         time assign this Agreement, in whole or in part, to one or more of its
         then affiliates, and to the extent of any such assignment, the relevant
         references in this agreement to shall apply to such affiliate.



                                       7


11.7.    To the extent that, and only to the extent that, this Agreement
         otherwise obligates Bear Stearns to reimburse Predictive for any travel
         (including lodging, meals or similar expenses), such obligation is
         subject to the following conditions and limitations: (a) the travel
         expenses may not exceed the expense of travel to the relevant Bear
         Stearns facility from the nearest Predictive facility or office, (b)
         any such travel must be at the request of Bear Stearns's designated
         liaison person, (c) Predictive provides Bear Stearns with a listing of

         not exceed $150 per day plus carrier travel (lowest coach fare), (e)
         Predictive makes travel arrangements via Bear Stearns's Travel
         Department, and (f) the travel is in accordance with Bear Stearns's
         Travel Policies/Procedures.

11.8.    Predictive acknowledges that, as is the custom and practice in Bear
         Stearns's industry, from time to time Bear Stearns monitors and/or
         records certain telephone lines and other communications devices going
         into or out of Bear Stearns's premises, and to the extent that any such
         monitoring and/or recording occurs relating to any telephone call and
         other communication going into or out of Bear Stearns's premises
         involving Predictive or any of its employees, agents and
         sub-contractors, then Predictive, on behalf of its self and its
         employees, agents and sub-contractors, consents thereto or will ensure
         such other party consents thereto.

Introduction
- --------------------------------------------------------------------------------

            Predictive Systems, Inc. (Predictive) is pleased to present this
            proposal to assist in the analysis and redesign of the [****]
            location at Bear, Stearns & Co. (Bear Stearns). We look forward to
            continuing our work with Bear Stearns as a strategic partner. Our
            engineering staff is experienced on the tools and requirements in
            performing a network analysis and redesign. This coupled with our
            knowledge of the Bear Stearns network, uniquely qualify us for the
            project.

            This proposal meets the requirements set forth in meetings and
            conversations with Bear Stearns during the 5 days period of 2/2/99 -
            2/9/99 and supported documentation that has been provided during
            those meetings.

Non-disclosure
- --------------------------------------------------------------------------------

            All information contained in this proposal and quotation is
            confidential and proprietary to Predictive Systems, constituting its
            trade secrets and privileged, confidential property. It is furnished
            to Bear Stearns in confidence, with the understanding that it will
            not, without written permission of Predictive Systems, be used for
            other than evaluation purposes or be disclosed to any third party.
            Duplication of this proposal and quotation is strictly forbidden,
            and all copies shall be returned to Predictive Systems upon our
            request.

Deadline for response

      Predictive Systems has developed a methodology to perform the type of
      analysis required for the design and migration of users to a new
      architecture. The overall process of the network analysis is geared
      towards the analytical evaluation of each building's internal traffic
      patterns and bandwidth utilization. Attached to this document is a
      description of the network analysis methodology and tools that will be
      used by Predictive Systems for this project. Below is a brief description
      of this process.

      The first step in this process is a basic network audit of the
      infrastructure to determine the traffic `flow'. Subsequently Predictive
      Systems will perform a data collection of protocol and traffic information
      to gauge network usage and to plan for the migration to the switched
      environment.

            The following three steps characterize the basic process involved:
                  o     Detailed Building Review and Inventory of Infrastructure
                  o     Data Collection: LAN/WAN Traffic Analysis; Protocol
                        Review
                  o     Report on Findings: Building Summary

Proposal for [****] Redesign
                                                                          Page 3


Project Component Description
- --------------------------------------------------------------------------------

The following lists the four components to the [****] redesign project. [****]
 Each component is described with a brief list of activities. The project
will require a [****] of the existing ECN network. Predictive will require
the assessment to understand the network prior to any additions or redesigns.

Current Network/Infrastructure Assessment
- --------------------------------------------------------------------------------

There are two main areas to the assessment, the first is a detailed inventory of
all communications equipment to the level of port, application and user
identification. The second is an analysis of the network usage over the building
and inter-building network, LAN segment utilization and Top Talkers are part of
the analysis that will be performed. The information gathered will be used in
the design and migration plans for the users onto the new architecture. Refer to
the Network Assessment Section of the document for details on how the assessment
will be performed and what tools will be used during the project.

Some of the activities are;
      o     Identify all networks to be analyzed
      o     Set-up Tools to be used (probes, data collection systems)
      o     Capture Data for over a 3 day period
      o     Analyze and document results of the segment
      o     Physical inventory of all devices to the port identification
      o     Document inventory with network segment diagrams and spreadsheets.

Centillion Extension Design and Implementation
- --------------------------------------------------------------------------------
                  [****] We will review current network capacity and offer
                  suggestions on successfully extending the networks to
                  [****].

                  Some of the activities are;
                  o     Identify subnets to extend
                  o     Work with Bear Stearns Engineering to develop a design
                        for subnet extension
                  o     Build out [****] extension
                  o     Test and burn in equipment
                  o     Integrate [****] design

Accelar Design and Implementation
- --------------------------------------------------------------------------------

            [****] The data collected during the segment analysis along with
            the current [****] will provide the required information to develop
            a design. The design and migration will provide the logical and
            physical requirements. The results will be the network diagrams,
            equipment lists, computer room requirements (cabling and cabinets)
            and configuration documentation. [****] Predictive Systems has
            extensive knowledge of these processes along with the Communications
            staff that will be involved in the projects.

            The activities involved are;

            o     Propose Network Design Documentation for review with Bear
                  Stearns Engineering.

            o     Utilizing the [****] for procurement (budget forms etc...)
                  and implementation scheduling.

            o     All preparation work prior to the implementation such as
                  project plans, configurations of the switches and any changes
                  required of the routers and firewalls.

            Installation of the equipment, burn in time for new devices,
            configuration of the devices, EMS templates for management and
            review and testing of [****] management. Finalization of the
            user migrations and business unit cut windows.

Cut-Over to Production
- --------------------------------------------------------------------------------

This component of the project is comprised requires the co-ordination with
business units and other Bear Stearns departments. The migration of users will
take place over multiple weeknights and weekends with post application testing
prior to the next business day.

      The following are some of the activities;

            o     Develop Project plans, [****] projects open for each migration
                  group along with following the procedures for getting windows
                  with clients.
            o     On-Site for the migration of users assisting the
                  Implementation team as needed during the cut. Verification
                  that all the devices are running properly and working with
                  Business Unit SA in application testing.
            o     On-Site for assistance first business day of running with the
                  new system.

Post Production Analysis
- --------------------------------------------------------------------------------

After the migration of all users to the switched network there will be a
performance analysis utilizing the some of the same tools and the pre-design
analysis. Due to the difference in topology [****] there cannot be the same
reports as the first analysis. Any and all the information that is available
will be collected and reported upon. The goal of the analysis is to evaluate
the differences in the utilization and capacity of the new network design.

Once the project is completed all the documentation and diagrams will be
transitioned to Operations. The identification of a dedicated operational
engineer would be helpful during the project and would assist with a smooth
transition from engineering to operations. [****] To ensure the successful
transition to operations there will be a meeting scheduled with operations to
set the requirements, documentation, configurations and diagrams.

================================================================================
Assumptions
- --------------------------------------------------------------------------------

            In developing this proposal, there are many assumptions Predictive
            Systems has made that can materially affect the outcome and cost of
            the project. Should any of these assumptions prove to be incorrect,
            exaggerated or underestimated, the scope and cost of the project may
            change significantly.

            In the event of any such material change in assumptions,
            requirements or specifications, Predictive will request a Change
            Order Authorization from Bear Stearns which must be signed by Bear
            Stearns prior to the change being incorporated into the project
            plan. The Change Order could be an addition or reduction of work,
            based on the circumstances.

General Project Assumptions
- --------------------------------------------------------------------------------

            1.    It is in Bear Stearn's estimation that the project will
                  require [****] to complete. This is assuming equipment
                  availability, business unit cut window availability,
                  pre-defined user moves schedules and no major changes to the
                  design standards.

            2.    Bear Stearns will facilitate the timely installation of
                  equipment, power and cabling system prior to initial build out
                  of new network.

            3.    This is a collaborative Engineering project whereby Predictive
                  Systems is providing staff augmentation based on Bear Stearn's
                  defined dates and deliverables.

            4.    Both Predictive and Bear Stearns will assign a single point of
                  contact for the engineering and a point of contact for the
                  implementation tasks.

            5.    Bear Stearns will provide adequate facilities, equipment and
                  communications lines for the Implementation Staging. Bear
                  Stearns will also provide a work area with a phone and a
                  network connection for each Predictive consultant.

            6.    [****] Any and all information that is available will be
                  used with collection methods similar to the first analysis.

            network technology serves two purposes: to make money and to save
            money.

            Predictive Systems' unique BusinessFirst(TM) methodology helps
            Fortune-1000 clients define, package, and measure network services.
            BusinessFirst is rooted in the concept that a company should run its
            IT organization as a business. Throughout the BusinessFirst process,
            Predictive Systems translates strategic business objectives into
            sound, achievable technology solutions. This approach ensures that
            the technology never obscures the business goals.

            Predictive Systems' BusinessFirst methodology can clarify the
            business requirements driving the project in specific, measurable
            terms. Predictive Systems quantifies factors such as business risk,
            total cost of ownership, and operational efficiency to build a
            complete financial justification for a network project. By
            instrumenting every system to measure and quantify the key factors
            that govern success, Predictive Systems turns complexity into
            clarity.

            Predictive Systems serves its clients with a collaborative practice
            structure that delivers both breadth and depth of experience to all
            aspects of a project. Predictive Systems has the people and

            works. When technology "gaps" are discovered in a client's network,
            or disparate systems need to communicate with one another,
            Predictive Systems' software developers build custom applications to
            solve these problems. These custom applications can turn a
            collection of products into an integrated system.

Predictive Systems' practice areas
- --------------------------------------------------------------------------------

            Predictive Systems' consultants are organized into areas of
            specialization, or practice areas. Although many engineers are
            cross-skilled in a variety of technologies, and many technologies
            span multiple practice areas, each practice area represents an
            aspect of network technology important enough to warrant
            specialization. In addition, the Software Development and Technical
            Publications departments span all practice areas. Resources from all
            of these groups are available to define and implement the
            technological solutions that best meet our clients' business needs.

Internetwork Design and Engineering practice
- --------------------------------------------------------------------------------

            Predictive Systems' Internetwork Design and Engineering
            (internetworking) practice area is dedicated to helping each client
            design and implement network solutions in support of their strategic
            business initiatives. To this end, we have created a team of
            seasoned professionals from the three major industry proving
            grounds--telecommunications providers, network equipment vendors,
            and Fortune-500 end users. Using their specialized technical skills,
            real-world industry experience, and methodologies that are needed to
            solve the problems associated with building and maintaining network
            foundations, Predictive Systems' internetwork consultants develop
            innovative network solutions that provide our clients with a
            measurable competitive advantage.

            Our Internetwork Design and Engineering staff has extensive
            experience with a wide variety of technologies and vendors. For some
            clients, our consultants are involved in both technology and vendor
            selection. Other clients have already selected the technology,
            vendor, or both. Regardless of the pre-existing condition,
            Predictive Systems offers a completely objective, "trusted advisor"
            approach to our clients. Our up-to-date knowledge of all of the
            major technologies and vendors is a significant part of the value
            Predictive Systems brings to a project.

            The Internetwork Design and Engineering practice fills the
            substantial gap in the marketplace between management consulting
            firms and technical staff augmentation services. With core
            competencies in the areas of Backbone Technology, LAN Switching, IP
            Management and Design, ATM, Remote Access, our versatile team
            contributes both technical depth and breadth to client engagements.
            Predictive Systems' team has the business acumen to translate
            business objectives into technical solutions, the technical skills
            to build the vision, the project skills to deliver the engagement on
            time and on budget, and the rigorous methodologies to ensure that
            the resulting system is manageable for a controlled, known cost.

            Predictive Systems' Internetwork Design and Engineering practice
            offers the following services:

            The following sections will detail the steps that will be taken in
            the development of the contingency plan.

[****]
- --------------------------------------------------------------------------------

            There are four major activities in the development of the
            contingency plan. The first activity is to identify all network
            components and possible Y2K events that will be covered under the
            Y2K Contingency Plan. The second is the research, testing and
            development of applications and tools that will be used to assist in
            the elimination of problems or early identification of potential
            problems. The third will be the identification and geographic
            distribution of parts and devices per vendor utilized in today's
            production network. The fourth is the restoration planning where the
            process and procedures will be documented on how to recover from a
            Y2K failure.

            The following will detail the process in the development of the
            Communications contingency plan.

Y2K Event Process Life Cycle
- --------------------------------------------------------------------------------

            The goal in this section is to identify potential device failure
            scenarios due to Y2K abnormalities. Each identified scenario is then
            reviewed for the devices effected and business priority. [****]

            Information and Identification of Network Components

            The Communications [****] Plan will cover a definitive set of
            devices and services. The first step in developing the plan is to

            [****]

            The use of existing inventories, diagrams and interviews of the
            communication engineers will be combined into a single listing of
            vendors and hardware device types. Along with identification of
            device type, the number of each device type and the criticality
            within the network will be critical to further [****]

            is to identify the effects of these events on Bear Stearns business.

            >     Communication Business Network Review

            The goal of the communication business network review is to identify
            the entire business system that supports given business function and
            the dependencies on the Communications services. Interviewing the
            Communications Business Engineering staff will collect the data.

Y2K Response Applications and Development
- --------------------------------------------------------------------------------

            [****] The first step will be to research the market place for
            programs that will assist in the identification of problems such as
            audit, calendar and timing systems that will provide flexibility to
            global changes in devices that did not respond properly to the "end
            of year" date change. [****] Additional tools will be evaluated as
            necessary.

            Some of the activities would be;

            1.    Identify applications in the marketplace that will assist in
                  the restoration or management of a Y2K problem.

            2.    Test and evaluate the applications to determine which of the
                  event scenarios would benefit, either in problem
                  identification and isolation or in problem restoration.

            The section is the planning for the number of resources, skillet
            requirements and the physical locations of the on-site engineers to
            carry out restoration plans will be identified for the Y2K coverage
            time period. The planning involves a review of the [****]. This
            analysis will provide the data needed to determine the number of
            resource and device spares.

            Resource Allocation Planning

            The allocation planning will detail the number of resources,
            skillets and geographic location that will be required for
            restoration of multiple outages simultaneously. There will be
            requirements for both Bear Stearns engineering resources and
            specialist from the Vendors with devices that are determined
            critical to the network.

            The plan will also outline the critical locations that require
            on-site engineers for a specific device type and the ability to
            leverage other engineers to cover multiple sites. The plan will
            provide a list that will identify the number and skillset required
            to resolve any of the problems that are identified [****]

            [****]

            Equipment Reserves and Distribution

            There are two avenues that must be reviewed with the identification
            of devices in reserve. The first is to determine the number of
            spares that should be on-site at each major location. The second is
            to determine an alternative network device to be used in place of
            the current device type when there is no remediation available.

            [****]

Assumptions
- --------------------------------------------------------------------------------

            In developing this proposal, there are many assumptions Predictive
            Systems has made that can materially affect the outcome and cost of
            the project. Should any of these assumptions prove to be incorrect,
            exaggerated, or underestimated, the scope and cost of the project
            may change significantly.

            In the event of any such material change in assumptions,
            requirements or specifications, Predictive will request a Change
            Order Authorization from Bear, Stearns & Co., which must be signed
            by Bear, Stearns & Co. prior to the change being incorporated into
            the

            project plan. The Change Order could be an addition or reduction of
            work, based on the circumstances.

General project assumptions
- --------------------------------------------------------------------------------

            1.    Bear Stearns' point of contact will provide project direction
                  for the Predictive resources for the duration of the project.

            2.    The fixed price proposal provided assumes a 45-hour workweek.
                  If review of the monthly time indicates excessive hours per
                  week, Predictive will bring that to Bear Stearns management's
                  attention in the form of a Change Order request.

            3.    Additional project requirements will be accommodated to the
                  best of the team's ability given the current project
                  requirements and time frames. Any impact to the current
                  project time frames will be detailed in writing to the Bear
                  project contact as they are identified by the Predictive team.

            4.    Bear, Stearns & Co. will also provide a work area with a phone
                  and a network connection for each Predictive consultant.

Specific project assumptions
- --------------------------------------------------------------------------------

            1.    All outages are considered Y2K-related during a specific
                  timeframe until proven otherwise.

            [****]

            5.    Bear Stearns will provide the list of Business Unit managers
                  responsible for participating in the contingency planning
                  process.

            6.    Senior management participation is critical, and will be
                  available for review and prioritization of Business Units.

            engineering team.

General router upgrade process
- --------------------------------------------------------------------------------

            In the course of the project, the Predictive Systems team will
            upgrade all routers to the code version that has been fully tested
            by the engineering group. All configuration changes and new hardware
            replacements will also be installed as per engineering
            specifications. The upgrade project will involve a specific process,
            which includes, but is not limited to, the following:

            [****]

            o     Determine the number of configuration versions in existence.

            o     For each configuration, develop cutover plan and fallback
                  plan.

            o     Procure all required components for cutover (hardware,
                  software, and cabling).

            o     Obtain and schedule cutover window from Bear Stearns.
                  Coordinate the cutover with other implementation activities.

            o     Stage the cutover.

            o     Perform the cutover.

            o     Test the new configuration.

            o     Document the new configuration.

            o     Assist Bear Stearns operations in monitoring cutover
                  environment to ensure it is stable.

            The Predictive Systems team will conform to and fully adopt Bear
            Stearns' implementation methodology. All implementation work will
            flow through the Bear Stearns project system.

            Other router configuration changes that will be included in the
            upgrade are:

            o     Changing router name to conform to new standards.

            o     Upgrading memory.

            o     Adding user ID password to conform to new standards.

                  ble for scheduling, assisting with configurations, equipment
                  procurement, maintaining project plans, technical leadership,
                  and preparing weekly status reports.

            o     Internetworking engineers: Internetworking engineers will be
                  used for all phases of this project. The engineers will
                  perform all tasks required for the upgrade and configuration
                  changes in the project. The engineering resources will follow
                  existing Bear Stearns project processes in performing these
                  tasks

Assumptions
- --------------------------------------------------------------------------------

            In developing this proposal, Predictive Systems has made many
            assumptions that could materially affect the outcome and cost of the
            project. Should any of these assumptions prove to be incorrect,
            exaggerated, or underestimated, the scope and cost of the project
            may change significantly.

            In the event of any such material change in assumptions,
            requirements, or specifications, Predictive Systems will request
            from Bear Stearns a change order authorization, which must be signed
            by Bear Stearns prior to the change being incorporated into the
            project plan. Based on circumstances, the change order could be an
            addition or reduction of work.

General project assumptions
- --------------------------------------------------------------------------------

            o     Device count: [****] This proposal is based on this
                  number of routers. If there are any major changes to the
                  number of devices to be upgraded or the work to be performed
                  on each router, a change order will be used to recalculate
                  project time and expense.

            o     Travel: This proposal includes no travel time or expenses for
                  travel outside of the New York metropolitan area. Should such
                  travel be required, actual travel and out-of-pocket costs will
                  be charged back to Bear Stearns.

            o     Single point of contact: Both Predictive Systems and Bear
                  Stearns will assign a single point of contact for the
                  implementation tasks.

            o     Dedication to task: The Predictive Systems team will be
                  dedicated to the [****], and will not be involved in [****].
                  If members of Predictive Systems' project team are required
                  for other tasks during the engagement, a separate purchase
                  vehicle must be established.

            o     Verification of router code: Prior to the start of this
                  project, there will be version testing for functionality and
                  interoperability, including for router models used in the EMS
                  systems.

            o     Configuration standards: Bear Stearns will provide written
                  configuration standards, such as the Clearnet naming
                  convention, user ID passwords, and any [****].

            o     Facility: Bear Stearns will provide adequate facilities,
                  equipment, and communications lines for the implementation
                  staging. Bear Stearns will also provide a work area with a
                  phone and a network connection for each Predictive Systems
                  engineer.

            o     Working hours: Due to the nature of this project, the
                  Predictive Systems engineers will be required to perform a
                  significant amount of off-hours work. This has been built into
                  the project plan and is reflected in the overall project cost.

Reporting methods

Status reports
- --------------------------------------------------------------------------------

            The Predictive Systems team will provide a weekly status report in
            electronic format to the Bear Stearns program manager. The report
            form will be brief, listing any items that were completed that week
            and the open items for the next week. The purpose of the reports is
            to provide weekly information on the status of the project and any
            outstanding issues from the week. The reports will be available on
            Monday morning.

About Predictive Systems
- --------------------------------------------------------------------------------

            Predictive Systems is a network consulting and integration firm that
            specializes in the design, management, and security of
            business-critical networks. Recognized in the industry for its
            vendor-independent perspective, the firm's expertise lies in solving
            multi-faceted, complex network problems. At Predictive Systems,
            network technology serves two purposes: to make money and to save
            money.

            Predictive Systems' unique BusinessFirst(TM) methodology helps
            Fortune-1000 clients define, package, and measure network services.
            BusinessFirst is rooted in the concept that a company should run its
            IT organization as a business. Throughout the BusinessFirst process,
            Predictive Systems translates strategic business objectives into
            sound, achievable technology solutions. This approach ensures that
            the technology never obscures the business goals.

            Predictive Systems' BusinessFirst methodology can clarify the
            business requirements driving the project in specific, measurable
            terms. Predictive Systems quantifies factors such as business risk,
            total cost of ownership, and operational efficiency to build a
            complete financial justification for a network project. By
            instrumenting every system to measure and quantify the key factors
            that govern success, Predictive Systems turns complexity into
            clarity.

            Predictive Systems serves its clients with a collaborative practice
            structure that delivers both breadth and depth of experience to all
            aspects of a project. Predictive Systems has the people and
            processes to build networks that mean business.

Predictive Systems' services
- --------------------------------------------------------------------------------

            Predictive Systems offers a unique combination of expertise in
            network management, performance management, internetwork
            engineering, information security, and software development.
            Predictive Systems' engineers combine skill in network management
            applications with real-world experience using state-of-the-art
            internetwork technologies, including Asynchronous Transfer Mode
            (ATM) and Asymmetric Digital Subscriber Line (ADSL), to address the
            multi-faceted challenges of designing and managing mission-critical

            works. When technology "gaps" are discovered in a client's network,
            or disparate systems need to communicate with one another,
            Predictive Systems' software developers build custom applications to
            solve these problems. These custom applications can turn a
            collection of products into an integrated system.

Predictive Systems' practice areas
- --------------------------------------------------------------------------------

            Predictive Systems' consultants are organized into areas of
            specialization, or practice areas. Although many engineers are
            cross-skilled in a variety of technologies, and many technologies
            span multiple practice areas, each practice area represents an
            aspect of network technology important enough to warrant
            specialization. In addition, the Software Development and Technical
            Publications departments span all practice areas. Resources from all
            of these groups are available to define and implement the
            technological solutions that best meet our clients' business needs.

Internetwook Design and Engineering practice
- --------------------------------------------------------------------------------

            Predictive Systems' Internetwork Design and Engineering
            (internetworking) practice area is dedicated to helping each client
            design and implement network solutions in support of their strategic
            business initiatives. To this end, we have created a team of
            seasoned professionals from the three major industry proving
            grounds--telecommunications providers, network equipment vendors,
            and Fortune-500 end users. Using their specialized technical skills,
            real-world industry experience, and methodologies that are needed to
            solve the problems associated with building and maintaining network
            foundations, Predictive Systems' internetwork consultants develop
            innovative network solutions that provide our clients with a
            measurable competitive advantage.

            Our Internetwork Design and Engineering staff has extensive
            experience with a wide variety of technologies and vendors. For some
            clients, our consultants are involved in both technology and vendor
            selection. Other clients have already selected the technology,
            vendor, or both. Regardless of the pre-existing condition,
            Predictive Systems offers a completely objective, "trusted advisor"
            approach to our clients. Our up-to-date knowledge of all of the
            major technologies and vendors is a significant part of the value
            Predictive Systems brings to a project.

            The Internetwork Design and Engineering practice fills the
            substantial gap in the marketplace between management consulting
            firms and technical staff augmentation services. With core
            competencies in the areas of Backbone Technology, LAN Switching, IP
            Management and Design, ATM, Remote Access, our versatile team
            contributes both technical depth and breadth to client engagements.
            Predictive Systems' team has the business acumen to translate
            business objectives into technical solutions, the technical skills
            to build the vision, the project skills to deliver the engagement on
            time and on budget, and the rigorous methodologies to ensure that
            the resulting system is manageable for a controlled, known cost.

            Predictive Systems' Internetwork Design and Engineering practice
            offers the following services:

            o     Advanced Technology Planning and Migration

            o     Core Backbone and Campus Network Design and Implementation

            There will be a weekly status meetings with Bear, Stearns & Co. on
            the overall project. The meeting should be held at the same time and
            day every week (the time and day need to be determined). The meeting
            will be to review any work that was performed by the Predictive
            Systems' team and review the open items list of work that is
            scheduled for the next week. This meeting will also provide a
            platform for reviewing any new issues or additional project

            In developing this proposal, there are many assumptions Predictive
            Systems has made that can materially affect the outcome and cost of

            the project. Should any of these assumptions prove to be incorrect,
            exaggerated, or underestimated, the scope and cost of the project
            may change significantly.

            In the event of any such material change in assumptions,
            requirements or specifications, Predictive will request a Change
            Order Authorization from Bear, Stearns & Co. which must be signed by
            Bear, Stearns & Co. prior to the change being incorporated into the
            project plan. The Change Order could be an addition or reduction of
            work, based on the circumstances.

General project assumptions
- --------------------------------------------------------------------------------

            1.    Bear Stearns point of contact will provide project direction
                  for the Predictive resources for the duration of the project.

            2.    The Fixed price proposal provided assumes a 40-hour work week.
                  If review of the monthly time indicates excessive hours per
                  week Predictive will bring that to Bear Stearns management's
                  attention in the form of a Change Order request.

            3.    Additional project requirements will be accommodated to the
                  best of the team's ability given the current project
                  requirements and time frames. Any impact to the current
                  project time frames will be detailed in writing to the Bear
                  project contact as they are identified by the Predictive team.

            4.    Bear, Stearns & Co. will also provide a work area with a phone
                  and a network connection for each Predictive consultant.

About Predictive Systems
- --------------------------------------------------------------------------------

            Predictive Systems is a network consulting and integration firm that
            specializes in the design, management, and security of
            business-critical networks. Recognized in the industry for its
            vendor-independent perspective, the firm's expertise lies in solving
            multi-faceted, complex network problems. At Predictive Systems,
            network technology serves two purposes: to make money and to save
            money.

            Predictive Systems' unique BusinessFirst(TM) methodology helps
            Fortune-1000 clients define, package, and measure network services.
            BusinessFirst is rooted in the concept that a company should run its
            IT organization as a business. Throughout the BusinessFirst process,
            Predictive Systems translates strategic business objectives into
            sound, achievable technology solutions. This approach ensures that
            the technology never obscures the business goals.

            Predictive Systems' BusinessFirst methodology can clarify the
            business requirements driving the project in specific, measurable
            terms. Predictive Systems quantifies factors such as business risk,
            total cost of ownership, and operational efficiency to build a
            complete financial justification for a network project. By
            instrumenting every system to measure and quantify the key factors
            that govern success, Predictive Systems turns complexity into
            clarity.

            Predictive Systems serves its clients with a collaborative practice
            structure that delivers both breadth and depth of experience to all
            aspects of a project. Predictive Systems has the people and
            processes to build networks that mean business.

            works. When technology "gaps" are discovered in a client's network,
            or disparate systems need to communicate with one another,
            Predictive Systems' software developers build custom applications to
            solve these problems. These custom applications can turn a
            collection of products into an integrated system.

Predictive Systems' practice areas
- --------------------------------------------------------------------------------

            Predictive Systems' consultants are organized into areas of
            specialization, or practice areas. Although many engineers are cross
            skilled in a variety of technologies, and many technologies span
            multiple practice areas, each practice area represents an aspect of
            network technology important enough to warrant specialization. In
            addition, the Software Development and Technical Publications
            departments span all practice areas. Resources from all of these
            groups are available to define and implement the technological
            solutions that best meet our clients' business needs.

            seasoned professionals from the three major industry proving
            grounds--telecommunications providers, network equipment vendors,
            and Fortune-500 end users. Using their specialized technical skills,
            real-world industry experience, and methodologies that are needed to
            solve the problems associated with building and maintaining network
            foundations, Predictive Systems' internetworking consultants develop
            innovative network solutions that provide our clients with a
            measurable competitive advantage.

            Our Internetworking Design and Engineering staff has extensive
            experience with a wide variety of technologies and vendors. For some
            clients, our consultants are involved in both technology and vendor
            selection. Other clients have already selected the technology,
            vendor, or both. Regardless of the pre-existing condition,
            Predictive Systems offers a completely objective, "trusted advisor"
            approach to our clients. Our up-to-date knowledge of all of the
            major technologies and vendors is a significant part of the value
            Predictive Systems brings to a project.

            The Internetworking Design and Engineering practice fills the
            substantial gap in the marketplace between management consulting
            firms and technical staff augmentation services. With core
            competencies in the areas of Backbone Technology, LAN Switching, IP
            Management and Design, ATM, Remote Access, our versatile team
            contributes both technical depth and breadth to client engagements.
            Predictive Systems' team has the business acumen to translate
            business objectives into technical solutions, the technical skills
            to build the vision, the project skills to deliver the engagement on
            time and on budget, and the rigorous methodologies to ensure that
            the resulting system is manageable for a controlled, known cost.

            Predictive Systems' Internetworking Design and Engineering practice
            offers the following services:

            o     Advanced Technology Planning and Migration

            o     Core Backbone and Campus Network Design and Implementation

            electronic format to the Bear, Stearns & Co. Program Manager. The
            report form will be brief; listing any items that were completed
            that week and the open items for the next week. The purpose of the
            reports is to provide weekly information on the status of the
            project and any outstanding issues from the week. The reports will
            be available on Monday morning.

            day every week (the time and day need to be determined). The meeting
            will be to review any work that was performed by the Predictive
            Systems' team and review the open items list of work that is
            scheduled for the next week. This meeting will also provide a
            platform for reviewing any new issues or additional project
            requirements.

Assumptions
- --------------------------------------------------------------------------------

            In developing this proposal, there are many assumptions Predictive
            Systems has made that can materially affect the outcome and cost of
            the project. Should any of these assumptions prove to be incorrect,
            exaggerated, or underestimated, the scope and cost of the project
            may change significantly.

            In the event of any such material change in assumptions,
            requirements or specifications, Predictive will request a Change
            Order Authorization from Bear, Stearns & Co. which must be signed by
            Bear, Stearns & Co. prior to the change being incorporated into the
            project plan. The Change Order could be an addition or reduction of
            work, based on the circumstances.
