Item 14. Indemnification of Directors and Officers

     The Registrant's Amended and Restated Certificate of Incorporation in
effect as of the date hereof (the "Certificate") provides that, except to the
extent prohibited by the Delaware General Corporation Law, as amended (the
"DGCL"), the Registrant's directors shall not be personally liable to the
Registrant or its stockholders for monetary damages for any breach of fiduciary
duty as directors of the Registrant. Under the DGCL, the directors have a
fiduciary duty to the Registrant which is not eliminated by this provision of
the Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of nonmonetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to the Registrant, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by the DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws. The Registrant maintains liability
insurance for its officers and directors.

     Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Registrant may fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative)
by reason of the fact that such person is or was a director or officer of the
Registrant, or is or was serving at the request of the Registrant as a


                                      II-1
<PAGE>

director or officer of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding.

     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

       of this registration statement in reliance upon Rule 430A and contained
       in a form of prospectus filed by the registrant pursuant to Rule 424
       (b)(1) or (4), or 497(h) under the Securities Act of 1933, shall be
       deemed to be part of this registration statement as of the time it was
       declared effective.

   (2) For the purpose of determining any liability under the Securities Act
       of 1933, each post-effective amendment that contains a form of
       prospectus shall be deemed to be a new registration statement relating
       to the securities offered therein, and this offering of such securities
       at that time shall be deemed to be the initial bona fide offering
       thereof.

     Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

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 networks.
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.

Our Internetwork Design and Engineering staff has extensive experience with a
wide variety of technologies and vendors. For some clients, our consultants are

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 marketplace between management consulting firms and technical staff
augmentation services. With core competencies in the areas of Backbone

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 networks.
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.

There are an estimated [***] in the Bear Stearns network (not including [***].
The majority of the [***] can be [***] without a site visit.

Predictive Systems' approach
- --------------------------------------------------------------------------------

[***] familiar with Bear Stearns' project process will lead the project team.
Their activities will include all project management activities such as
scheduling, project timeline distribution, assistance with configuration,
equipment procurement and weekly status reports. A [***] will provide technical
leadership for all aspects of the projects. An [***] will also be assigned to
the project for the [***]. Once the planning and staging phase is completed by
[***], another [***] will join the team. Upon the completion of the [***], the
[***] will be replaced with a [***] for the duration of the project.

The approach is to set up the [***], project [***]. This will guarantee a smooth
[***] schedule with NO impact on the [***].

Below is a general description of the [***] activities, followed by a detailed
description of the specific changes to be made by each engineering team.

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

Over the course of the project, the Predictive Systems team will [***] all [***]

also be installed as per engineering specifications. Both [***] subprojects will
involve a specific process, which includes, but is not limited to, the
following:

[***] and associated tasks will require the following processes to be completed
in accordance with Bear Stearns [***].

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   [***]: There are an estimated [***] (including the [***]) in the Bear
    Stearns network. This proposal is based on this number of [***]. If there
    are any major changes to the number of [***] to be [***] or the work to be
    performed on each [***], 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 [***] tasks.

o   Dedication to task: The Predictive Systems team will be dedicated to the
    [***], and will not be involved in other [***] support activities. 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 [***]: Prior to the start of this project, there will be
    version testing for [***], including for [***].

o   Configuration standards: Bear Stearns will provide written configuration
    standards, such as the [***], 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 consultant.


               Owner: [***] / Subject to non-disclosure agreement
                                      [***]

o   Working hours: Due to the nature of this project, the Predictive Systems
    consultants 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.

Status meetings
- --------------------------------------------------------------------------------

There will be weekly status meetings with Bear Stearns 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 requirements.

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 networks.
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.

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 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.

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

This proposal was generated based on a request by [***] and [***] of the
[***] at Bear, Stearns & Co. As a result of conversations with [***], it is the
understanding of Predictive Systems that there are several key areas where we
can assist Bear, Stearns & Co. regarding implementation projects scheduled over
the next 3 months. The primary area of concern is the resource availability of
implementation to work with engineering on new technology that is currently
under deployment and the on-going daily implementation work from various other
projects already underway.

 The following proposal addresses those areas and more fully describes the
capabilities that Predictive can deliver for this and future consulting
engagements. Predictive Systems has profiled the resources that are required to
conduct the services discussed.

Project Background
- --------------------------------------------------------------------------------

      First Union has made a tremendous investment in providing banking services
      [***]. At this time, the [***]. To do so, First Union continues to offer
      [***] to [***] customers at an extremely rapid rate.

      First Union has identified that the [***] availability can be achieved
      [***]. This project is the first step in a direction to fully manage all
      aspects of the [***] space in support of achieving maximum availability.

      The project consists of the design and deployment of [***]. This includes
      [***] for up to but not to exceed [***]. All [***] to be placed under
      [***] are [***]. The deployment also consists of [***].

      The First Union National Bank [***] contains the [***]. First Union has
      made a [***] in these areas.

      Predictive Systems proposes a [***] to meet these needs. The approach and
      methodology are more fully described below.

Project Description
- --------------------------------------------------------------------------------

      Predictive Systems proposes to build this proof of concept with the
      assumption that we are responsible for systems and network administration,
      application administration, and end-to-end testing and analysis. See Table
      1 on the following page for details.

Reporting Methods
- --------------------------------------------------------------------------------



Status Reports
- --------------------------------------------------------------------------------

      Predictive Systems' team will provide a weekly status report in electronic
      format to the First Union 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 by Friday at 9AM.

Status Meetings
- --------------------------------------------------------------------------------

      There will be weekly status meetings with First Union on the overall
      project. The meeting should be held at the same time and day every week

Proposed Statement of Work
- --------------------------------------------------------------------------------

[***]
- --------------------------------------------------------------------------------
This SOW details the activities of Predictive Systems' [***]. The team will be
responsible for implementing enhancements to the current system to support new
requirements that have emerged since the original [***] was developed. The [***]
functionality enhances the current system functionality in the areas depicted in
Table 1.

[***]
- --------------------------------------------------------------------------------
The [***] system implementation will involve some up-front analysis and
requirements review work followed by the implementation of the identified
functionality. However, unlike a ground-up integration project, and because the
current production [***] serves as the basis for the development of this phase
of enhancements, the [***].

Under the plan recommended in this SOW, the [***] system enhancements will
be delivered in stages, with the most important functionality delivered first.
This staged implementation model was successful during the [***] deployment
cycle. Figure 1 provides a conceptual model for the staged delivery approach.

Description of Project Tasking
- --------------------------------------------------------------------------------
Because the most important functionality is delivered first, the [***] users'
critical needs can be met sooner. Each staged delivery presents tangible
evidence of the project's progress and gives the end-user a chance to review the
interim products and provide feedback to the project team prior to the delivery
of the final system. This methodology allows a series of adjustments to be made
to the system in a controlled fashion, with user input, rather than waiting to
the end of the project to make a massive amount of change. In a series of staged
deliveries, the project progresses along a path that includes the steps
described in the rest of this section .

Figure 1 Staged Delivery Model

Requirements Review and Workflow Definition

The requirements review and workflow definition stage of the [***] deployment
involves spending some time with the end-user community to develop a prioritized
list of functional requirements to be deployed in a staged fashion. The [***]
staff has been exposed to the [***]; therefore, a fast-track approach for
requirements review can be utilized by building upon the most desirable
functions from the system and developing new functionality where required.
Although much of the functionality that has been implemented during the [***]
effort was defined during the [***] design task, many of the requirements have
changed over time. However, rather than conducting a lengthy requirements review
and workflow definition process, this task will be conducted as an on-going
iterative process.

Program Management Summary
- --------------------------------------------------------------------------------


Status Meetings
- --------------------------------------------------------------------------------

          There will be weekly status meetings with Qwest on the overall
          project. The meeting should be held at the same time of day every week
          (the time and day have yet to be determined). The meeting will focus
          on reviewing any work that was performed by the Qwest/Predictive
          Systems team and reviewing any open items that are scheduled for the
          next week's period. This meeting will also provide a platform for
          reviewing any new issues or additional project requirements.

Project Schedule
- --------------------------------------------------------------------------------

          Assuming that independent tasks are performed at the same time, this
          project will take approximately [***] to complete. This
          schedule is dependent upon the availability of information and access
          to Qwest staff as required.

          Project dates are subject to change based on project implementation
          details and will be provided to the Qwest Program Manager, as
          modifications are required. Weekly written status reports will be
          provided to Qwest indicating progress made since the last reporting
          period, progress to date, issues and concerns, and action items (new
          or outstanding).

Status Meetings
- --------------------------------------------------------------------------------

There will be weekly status meetings with Qwest on the overall project. The
meeting should be held at the same time of day every week (the time and day have
yet to be determined). The meeting will focus on reviewing any work that was
performed by the Qwest/Predictive Systems team and reviewing any open items that
are scheduled for the next week's period. This meeting will also provide a
platform for reviewing any new issues or additional project requirements.

Project Schedule
- --------------------------------------------------------------------------------

Assuming that independent tasks are performed at the same time, this project
will take approximately [***] calendar months to complete. This schedule is
dependent upon the availability of information and access to Qwest staff as
required.

Project dates are subject to change based on project implementation details and
will be provided to the Qwest Program Manager, as modifications are required.
Weekly written status reports will be provided to Qwest indicating progress made
since the last reporting period, progress to date, issues and concerns, and
action items (new or outstanding).

A detailed project plan will be delivered at the conclusion of the first week of
work on this SOW based on priorities as defined by Qwest and Predictive Systems.

  Systems cannot guarantee that new work or changes to the scope defined in this
  SOW can be completed by the stated due date. All changes to the scope of this
  SOW must be agreed to by Predictive Systems and Qwest.

o Development environment not currently available, i.e. the short-term
  development will be done on the production box. [***]

o Timely access to Qwest personnel and technical information will be provided in
  order to meet project milestones and to stay within the bounds of the costs
  estimates.

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 networks.
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.

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 networks.
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.

                  sign the Change Request, indicating the acceptance of the
                  changes by the parties.

          is given adequate notice and the ability to challenge such required
          disclosure.
   12.4.2 Neither party shall disclose, advertise, or publish the terms and
          conditions of this Agreement without the prior written consent of the

                 secret information of Cisco, as well as any information posted
                 on CCO. Customer shall at all times, both during the term of

                 Information other than as expressly authorized by Cisco under
                 this Agreement, nor shall Customer disclose any such
                 Confidential Information to third parties without Cisco's
                 written consent. Customer further agrees to immediately return
                 to Cisco all Confidential Information (including copies
                 thereof) in Customer's possession, custody, or control upon
                 termination of this Agreement at any time and for any reason.
                 The obligations of confidentiality shall not apply to
                 information which (a) has entered the public domain except
                 where such entry is the result of Customer's breach of this
                 Agreement; (b) prior to disclosure hereunder was already
                 rightfully in Customer's possession; (c) subsequent to
                 disclosure hereunder is obtained by Customer on a
                 nonconfidential basis from a third party who has the right to
                 disclose such information to the Customer; (d) is required to
                 be disclosed pursuant to a court order, so long as Cisco is
                 given adequate notice and the ability to challenge such
                 required disclosure.

         12.4.2  Neither party shall disclose, advertise, or publish the terms
                 and conditions of this Agreement without the prior written
                 consent of the other party. Any press release or publication
                 regarding this Agreement is subject to prior review and written
                 approval of the parties.

12.5 This Agreement is the complete agreement between the parties hereto
     concerning the subject matter of this Agreement and replaces any prior or
     contemporaneous oral or written communications between the parties. There

5. CHANGE MANAGEMENT PROCEDURES.

   5.1 It may become necessary to amend this Statement of Work for reasons
       including, but not limited to, the following:
       5.1.1  Cisco's and/or Customer's changes to the scope of work and/or
              specifications for the Deliverables,
       5.1.2  Non-availability of resources which are beyond either party's
              control; and/or,
       5.1.3  Environmental or architectural impediments not previously
              identified.

   5.2 In the event either party desires to change this Statement of Work, the
       following procedures will apply:

       5.2.1 The party requesting the change will deliver a Change Request
             document (Appendix C) to the other party. The Change Request will
             describe the nature of the change, the reason for the change, and
             the effect the change will have on the scope of work, which may
             include changes to the Deliverables, and the schedule.
       5.2.2 A Change Request may be initiated by either party for any material
             changes to the SOW. The designated Program/Project Manager of the
             requesting party will review the proposed change with his/her
             counterpart. The parties will evaluate the Change Request and
             negotiate in good faith the changes to the Services and the
             additional charges, if any, required to implement the Change
             Request. If both parties agree to implement the Change Request, the
             appropriate authorized representatives of the parties will sign the
             Change Request, indicating the acceptance of the changes by the
             parties.
       5.2.3 Upon execution of the Change Request, said Change Request will be
             incorporated into, and made a part of this SOW.

   5.3 Whenever there is a conflict between the terms and conditions set forth
       in a fully executed Change Request and those set forth in the original
       SOW, or previous fully executed Change Request, the terms and conditions
       of the most recent fully executed Change Request shall prevail.

               Customer acknowledges that, in connection with this Agreement and
               its relationship with Cisco, it may obtain information relating
               to the Products or to Cisco, which is of a confidential and
               proprietary nature ("Confidential Information"). Such
               Confidential Information may include, but is not limited to,

               programs, schematics, software source documents, data, customer
               lists, financial information, and sales and marketing plans or
               information which Customer knows or has reason to know is
               confidential, proprietary or trade secret information of Cisco,
               as well as any information posted on CCO. Customer shall at all
               times, both during the term of this Agreement and for a period of
               at least three (3) years after its termination, keep in trust and
               confidence all such Confidential Information, and shall not use
               such Confidential Information other than as expressly authorized
               by Cisco under this Agreement, nor shall Customer disclose any
               such Confidential Information to third parties without Cisco's
               written consent. Customer further agrees to immediately return to
               Cisco all Confidential Information (including copies thereof) in
               Customer's possession, custody, or control upon termination of
               this Agreement at any time and for any reason. The obligations of
               confidentiality shall not apply to information which (a) has
               entered the public domain except where such entry is the result
               of Customer's breach of this Agreement; (b) prior to disclosure
               hereunder was already rightfully in Customer's possession; (c)
               subsequent to disclosure hereunder is obtained by Customer on a
               nonconfidential basis from a third party who has the right to
               disclose such information to the Customer; (d) is required to be
               disclosed pursuant to a court order, so long as Cisco is given
               adequate notice and the ability to challenge such required
               disclosure.

               Neither party shall disclose, advertise, or publish the terms and
               conditions of this Agreement without the prior written consent of
               the other party. Any press release or publication regarding this
               Agreement is subject to prior review and written approval of the
               parties.

     This Agreement is the complete agreement between the parties hereto
     concerning the subject matter of this Agreement and replaces any prior or
     contemporaneous oral or written communications between the parties. There

L.  CHANGE MANAGEMENT PROCESS

Introduction
A Change Request is necessary whenever a task or activity requires an approach
that is different than originally approved by the [***]. A Change Request (CR)
is required when the project budget, resources, scope, timeline is altered from
what was originally approved. A change includes an estimated five day or greater
impact to the schedule or a total of eight man-hours (i.e. 1 person for 8 hours
or 2 people for 4 hours) have been expended for an effort. The Change Request is
necessary regardless of whether the change is a result of new customer
requirements, changes in our systems, new information or technology, new
regulatory requirements, or unanticipated findings.

Purpose
Changes occur frequently throughout our development effort. Many times, those
changes are small. Some are deceptively small because they start out appearing
as something that might be accomplishable in a matter of hours or even minutes.
Unfortunately, these changes can grow to something that will take substantially
longer to complete (days, weeks or months) or may require the efforts of more
individuals than originally anticipated. Scope creep is the result of
uncontrolled change.

Our customers need to know the impact of changes and be given the opportunity to
decide if a change (required or not) is justifiable and whether it should be
deferred until a more appropriate time--particularly if those changes impact the
overall cost or schedule. For scheduling and impact assessment purposes,
management needs to be informed of all changes.

While we hope that everyone recognizes that any change may impact our cost and
schedule, customers frequently perceive changes as something we would not accept
unless we can do it without affecting our cost or schedule.

Change management and the use of a change request, enables the project team and
project manager to monitor and communicate changes as they occur. They also
allow the management team to acquire a commitment from the customer to pay for
those changes.

Instructions For Processing a Change Request:

o    Complete the form provided in this SOW and submit to the Project Manager
     via e-mail or by hard copy. The Project Manager will review the Change
     Request Form for completion. The Project Manager will input the form into
     tracking database. Project Managers will need to keep status on a weekly
     basis so that tracking database is maintained until the Change Request has
     been closed.

o    The Project Manager will insert an appropriate ID number and track the
     Change Request.

o    Be sure to consider cost and impact of the change on all phases of the
     project (e.g. design, documentation, testing) and add attachments to
     substantiate your findings or recommendations.

o    Submit the Change Request form to your Project Manager; retaining a copy
     for your own records. The project manager will meet with the Account
     Manager and Engagement Manager if necessary and decide on whether to
     implement the change requested. The Project Manager will notify you whether
     the change was approved, deferred or rejected.

M.  ISSUE MANAGEMENT PROCESS

An issue is a question, concern or request that is raised by any originator and
pertains to the project. An issue may later be reclassified as a Change Request
or incident negotiated, deferred, or deleted. Issues should be maintained in the
a tracking database.

Issue For Resolution: An Issue for Resolution is the name given to items logged
in a tracking database as an issue and they have a type code of IFR. The IFR
process is utilized to record, track, escalate, and resolve issues.

Issue Management Process: The Issue Management Process encompasses the methods
employed to track issues to their resolution. Project team members need to be
committed to the process of issue management to ensure accurate project controls
and tracking.

The Issue Management Process provides a structured method to initiate, track,
escalate, and resolve issues. The Project Manager is responsible for managing
project issues. Left unresolved, issues may impede or prohibit project-related
progress or development by delaying or suspending work effort.

The Client, any member of the client's team or the Cisco project team can
initiate issues at any time during the life of the project by submitting an
issue by phone or electronic mail to [***]. Addressing and resolving an issue
may require a change to the project scope, price/rate, and implementation
schedule if the client deems necessary. NOTE: Change to the project scope may
have a direct impact on the budget and implementation schedule.

Similar to the Change Management Process, Issue Management may occur at any time
during the life of the project. Issues may evolve into Change Requests, they may
be deferred, canceled, worked through and eliminated (closed or completed), or
simply tabled. Issues may be discovered to be related to incidents already
known, or change request already in the process. Issues sometimes require senior
management action, or even organization reaction. Issue will be entered in the
tracking database in the same fashion as Change Requests. Issues are coded IFRs,
which stands for Issue For Resolution, and implies that action is required.

Identify Issue: Any originator can identify an issue. After identification, the
originator will forward the issue via electronic mail or hard copy to the
Project Manager. (An IFR template is being created--until a form is created
submit issues in a format of your choice via electronic mail.)

Escalation of an Issue: Define the process to identify how to escalate the issue
to the next authority level until resolved.

Assign Responsibility: The Project Manager assigns the appropriate resource the
responsibility for action on the issue. A Project Team Member forwards the IFR
to the Project Manager. The Project Manager originates the IFR in the tracking
database. The Project Manager will produce a weekly report of all open issues
upon request.

Review Customer Issues with Customer: The Project Manager will review any
applicable issues with the customer as necessary otherwise all outstanding
Issues (as well as Change Requests) will be listed in the weekly status
report.Obtain Customer Approval: If the issue was resolved, and it requires
customer approval, the Project Manager will forward the documentation for
appropriate written signature(s).

Approve Status: If the issue was not resolved, the issue returns to the
Originator for a decision to: accept the current status of the item, escalate,
defer, or cancel (marked canceled and archived).

N.  Communication Approach

The primary form of communication will be via electronic-mail. As well, team
communication is encouraged through team status meetings (via telephone
conference) conducted by the Project Manager throughout the lifecycle of this
project (every Wednesday from 10:30 a.m. -12:30 p.m.). Remote team members are
provided with bridge numbers to participate remotely in the weekly team
meetings. The Project Manager or delegate will record meeting minutes and action
items during the status meetings and will finalize and publish this information
and other required reports via electronic-mail.

The Project Manager will brief the Senior Manager on the status of the project
on a weekly basis through the submission of a Weekly Status Report. Unless
otherwise notified or instructed, this report will be submitted to the Senior
Manager by 2 p.m. via electronic mail on each Friday throughout the lifecycle of
the project. Project Red Flag items will be brought to the attention of the
Account Manager and Engagement Manager as soon as the Project Manager is aware
the urgent issue exists and will also be reflected in the Weekly Status Report.

Project Team members are to keep the Project Manager abreast of the status of
their assignments on a weekly basis. At an interval reporting time agreed upon
by the project team (Status Reports are due to the Project Manager every Friday
by 1 p.m. CST), team members will forward an informal status report to the
Project Manager. The Project Manager will use this information to assist in the
management and facilitation of allocation of resources, labor hours, issues,
change requests, requirements, project scope, etc. The status reports will be
consolidated and forwarded to the client by 2 p.m. CST every Friday by 2 p.m.
CST.

Information can be transferred among project team members via electronic-mail
and hard copy. All decisions made informally such as by telephone must be
documented and filed with the Project Manager. Finalization of project decisions
are contingent upon written approval of the Project Manager, senior manager, and
customer. Work cannot be performed until the appropriate documentation and
written approval is received and filed through the Project Manager or delegate.

All change and issue communication must be documented. Change Requests and
Issues will be coordinated through the Project Manager on the appropriate
form(s) to the Cisco Account Manager. The Project Manager is the primary point
of contact to interface with the Account Manager and Customer. All change
requests and issues will be tracked via the tracking database.

The Cisco Project Manager will provide the necessary tracking reports on a
weekly basis to the entire team and Customer to assist in the facilitation of
the project. All members of the project team, Project Manager, Engagement
Manager, Account Manager, Customer, and technical consultants have software
applications that are compatible for interfacing. These electronic mediums are
strongly encourage so that team members and the customer are able to share
information:

MS Word 97
MSExcel97
MSProject 98
MSAccess 97
electronic mail

L.  CHANGE MANAGEMENT PROCESS

Introduction
A Change Request is necessary whenever a task or activity requires an approach
that is different than originally approved by the [***]. A Change Request (CR)
is required when the project budget, resources, scope, timeline is altered from
what was originally approved. A change includes an estimated five day or greater
impact to the schedule or a total of eight man-hours (i.e. 1 person for 8 hours
or 2 people for 4 hours) have been expended for an effort. The Change Request is
necessary regardless of whether the change is a result of new customer
requirements, changes in our systems, new information or technology, new
regulatory requirements, or unanticipated findings.

Purpose
Changes occur frequently throughout our development effort. Many times, those
changes are small. Some are deceptively small because they start out appearing
as something that might be accomplishable in a matter of hours or even minutes.
Unfortunately, these changes can grow to something that will take substantially
longer to complete (days, weeks or months) or may require the efforts of more
individuals than originally anticipated. Scope creep is the result of
uncontrolled change.

Our customers need to know the impact of changes and be given the opportunity to
decide if a change (required or not) is justifiable and whether it should be
deferred until a more appropriate time--particularly if those changes impact the
overall cost or schedule. For scheduling and impact assessment purposes,
management needs to be informed of all changes.

While we hope that everyone recognizes that any change may impact our cost and
schedule, customers frequently perceive changes as something we would not accept
unless we can do it without affecting our cost or schedule.

Change management and the use of a change request, enables the project team and
project manager to monitor and communicate changes as they occur. They also
allow the management team to acquire a commitment from the customer to pay for
those changes.

Instructions For Processing a Change Request:

o    Complete the form provided in this SOW and submit to the Project Manager
     via e-mail or by hard copy. The Project Manager will review the Change
     Request Form for completion. The Project Manager will input the form into
     tracking database. Project Managers will need to keep status on a weekly
     basis so that tracking database is maintained until the Change Request has
     been closed.

o    The Project Manager will insert an appropriate ID number and track the
     Change Request.

o    Be sure to consider cost and impact of the change on all phases of the
     project (e.g. design, documentation, testing) and add attachments to
     substantiate your findings or recommendations.

o    Submit the Change Request form to your Project Manager; retaining a copy
     for your own records. The project manager will meet with the Account
     Manager and Engagement Manager if necessary and decide on whether to
     implement the change requested. The Project Manager will notify you whether
     the change was approved, deferred or rejected.

M.  ISSUE MANAGEMENT PROCESS

An issue is a question, concern or request that is raised by any originator and
pertains to the project. An issue may later be reclassified as a Change Request
or incident negotiated, deferred, or deleted. Issues should be maintained in the
a tracking database.

Issue For Resolution: An Issue for Resolution is the name given to items logged
in a tracking database as an issue and they have a type code of IFR. The IFR
process is utilized to record, track, escalate, and resolve issues.

Issue Management Process: The Issue Management Process encompasses the methods
employed to track issues to their resolution. Project team members need to be
committed to the process of issue management to ensure accurate project controls
and tracking.

The Issue Management Process provides a structured method to initiate, track,
escalate, and resolve issues. The Project Manager is responsible for managing
project issues. Left unresolved, issues may impede or prohibit project-related
progress or development by delaying or suspending work effort.

The Client, any member of the client's team or the Cisco project team can
initiate issues at any time during the life of the project by submitting an
issue by phone or electronic mail to [***]. Addressing and resolving an issue
may require a change to the project scope, price/rate, and implementation
schedule if the client deems necessary. NOTE: Change to the project scope may
have a direct impact on the budget and implementation schedule.

Similar to the Change Management Process, Issue Management may occur at any time
during the life of the project. Issues may evolve into Change Requests, they may
be deferred, canceled, worked through and eliminated (closed or completed), or
simply tabled. Issues may be discovered to be related to incidents already
known, or change request already in the process. Issues sometimes require senior
management action, or even organization reaction. Issue will be entered in the
tracking database in the same fashion as Change Requests. Issues are coded IFRs,
which stands for Issue For Resolution, and implies that action is required.

Identify Issue: Any originator can identify an issue. After identification, the
originator will forward the issue via electronic mail or hard copy to the
Project Manager. (An IFR template is being created--until a form is created
submit issues in a format of your choice via electronic mail.)

Escalation of an Issue: Define the process to identify how to escalate the issue
to the next authority level until resolved.

Assign Responsibility: The Project Manager assigns the appropriate resource the
responsibility for action on the issue. A Project Team Member forwards the IFR
to the Project Manager. The Project Manager originates the IFR in the tracking
database. The Project Manager will produce a weekly report of all open issues
upon request.

Review Customer Issues with Customer: The Project Manager will review any
applicable issues with the customer as necessary otherwise all outstanding
Issues (as well as Change Requests) will be listed in the weekly status
report.Obtain Customer Approval: If the issue was resolved, and it requires
customer approval, the Project Manager will forward the documentation for
appropriate written signature(s).

Approve Status: If the issue was not resolved, the issue returns to the
Originator for a decision to: accept the current status of the item, escalate,
defer, or cancel (marked canceled and archived).

N.  Communication Approach

The primary form of communication will be via electronic-mail. As well, team
communication is encouraged through team status meetings (via telephone
conference) conducted by the Project Manager throughout the lifecycle of this
project (every Wednesday from 10:30 a.m. -12:30 p.m.). Remote team members are
provided with bridge numbers to participate remotely in the weekly team
meetings. The Project Manager or delegate will record meeting minutes and action
items during the status meetings and will finalize and publish this information
and other required reports via electronic-mail.

The Project Manager will brief the Senior Manager on the status of the project
on a weekly basis through the submission of a Weekly Status Report. Unless
otherwise notified or instructed, this report will be submitted to the Senior
Manager by 2 p.m. via electronic mail on each Friday throughout the lifecycle of
the project. Project Red Flag items will be brought to the attention of the
Account Manager and Engagement Manager as soon as the Project Manager is aware
the urgent issue exists and will also be reflected in the Weekly Status Report.

Project Team members are to keep the Project Manager abreast of the status of
their assignments on a weekly basis. At an interval reporting time agreed upon
by the project team (Status Reports are due to the Project Manager every Friday
by 1 p.m. CST), team members will forward an informal status report to the
Project Manager. The Project Manager will use this information to assist in the
management and facilitation of allocation of resources, labor hours, issues,
change requests, requirements, project scope, etc. The status reports will be
consolidated and forwarded to the client by 2 p.m. CST every Friday by 2 p.m.
CST.

Information can be transferred among project team members via electronic-mail
and hard copy. All decisions made informally such as by telephone must be
documented and filed with the Project Manager. Finalization of project decisions
are contingent upon written approval of the Project Manager, senior manager, and
customer. Work cannot be performed until the appropriate documentation and
written approval is received and filed through the Project Manager or delegate.

All change and issue communication must be documented. Change Requests and
Issues will be coordinated through the Project Manager on the appropriate
form(s) to the Cisco Account Manager. The Project Manager is the primary point
of contact to interface with the Account Manager and Customer. All change
requests and issues will be tracked via the tracking database.

The Cisco Project Manager will provide the necessary tracking reports on a
weekly basis to the entire team and Customer to assist in the facilitation of
the project. All members of the project team, Project Manager, Engagement
Manager, Account Manager, Customer, and technical consultants have software
applications that are compatible for interfacing. These electronic mediums are
strongly encourage so that team members and the customer are able to share
information:

MSExcel97
MSProject 98
MSAccess 97
electronic mail

("SOW"). PREDICTIVE SYSTEMS will perform the professional services and deliver
the materials as described in the SOW (collectively "Services"). To the extent
of any inconsistency between this Agreement and the SOW, the SOW shall govern.


2.       Term
This Agreement shall commence on the effective date specified above and shall

PREDICTIVE SYSTEMS shall indemnify MNS and its Customers and hold them harmless
from the same, and any penalties, fines, interest, costs or other obligations
with respect thereto. MNS may, upon written notice, request that PREDICTIVE
SYSTEMS remove or reassign certain personnel based on the individual's skills,
background, performance or failure to perform as determined by MNS.


4.       Pricing and Payment Terms
a. Service. MNS shall pay PREDICTIVE SYSTEMS for the Services in accordance with
the rates established in the attached Exhibit "B" or any SOW. In the event of
inconsistency between the rates shown in the SOW and Exhibit "B", the rates
agreed upon in the mutually executed SOW shall govern. Services will be invoiced
on a monthly basis.

and actual expenses in accordance with the PREDICTIVE SYSTEMS Travel and Expense
policy, a copy of which shall be provided to MNS. Expense invoices will include
a summary of expenses by major category. Expenses will be invoiced on a monthly
basis.

c. Payment Terms. Invoices are due within 30 days after receipt. MNS agrees to
pay a late charge of one and one half percent (1 1/2%) per month or the maximum
lawful rate, whichever is less, for all amounts not paid within thirty (30) days
of receipt of invoice.

d. Taxes. MNS shall be responsible for all applicable taxes except for taxes
imposed on the net income of PREDICTIVE SYSTEMS or taxes related to PREDICTIVE
SYSTEMS consultants as stated in Section 3 "Independent Contractor".

professional and workmanlike manner and that they will be in conformance with
the requirements of the SOW. The Services will be deemed to be accepted unless
MNS notifies PREDICTIVE SYSTEMS in writing within sixty (60) days after
performance that the Services did not conform to this warranty. PREDICTIVE
SYSTEMS will promptly correct any non-conformities and will notify MNS in
writing that the non-conformities have been corrected; and the Services will be
deemed to be accepted after thirty (30) days unless MNS notifies PREDICTIVE
SYSTEMS that the non-conformities have not been corrected.

6.       Insurance
Throughout the term of this Agreement, PREDICTIVE SYSTEMS will maintain the
following minimum amounts of insurance: (i) workers' compensation, statutory
minimums, (ii) commercial general liability with a minimum of $1,000,000 per

upon request. Each policy shall provide that it will not be canceled or reduced
except upon not less than 30 days notice to MNS.


7.       Termination

other party fails to perform its material obligations under this Agreement and
such failure is not corrected within thirty (30) days after receipt of written
notice of the breach from the non-breaching party, or (ii) either party is
appointed a trustee for the benefit of creditors, becomes insolvent, bankrupt or

                                         FIRST ADDENDUM TO
                      MASTER PROFESSIONAL SERVICES AGREEMENT NO. MNS00352199

         THIS ADDENDUM ("Addendum"), with an effective date July 26, 1999, is
entered into by and between BellSouth MNS, Inc. ("BellSouth") and Predictive
Systems, Inc. ("Predictive). The Addendum modifies Master Professional Services
Agreement No. MNS00352199, with an effective date of May 14, 1999 ("MPSA").

         WHEREAS, the parties have entered into a MPSA which enables Predictive
to perform professional services for BellSouth; and

         WHEREAS, the parties have determined that certain rules of engagement
and restriction of actions should be added to the MPSA;

         NOW, THEREFORE IN CONSIDERATION of the foregoing, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, BellSouth and Predictive agree to amend the MPSA by adding the
following terms to the MPSA:

15. RIGHT OF FIRST REFUSAL

          a. During the Term of this Addendum, Predictive shall have a right of
             first refusal to perform the services itemized in Schedule 15.1,
             which BellSouth obtains the opportunity to perform. Prior to
             submitting a written proposal for such services to a potential
             Customer, BellSouth shall submit to Predictive an offer ("Offer")
             describing the proposed Project in reasonable detail, including the
             services to be performed by Predictive. Predictive shall have two
             (2) business days after receipt of the Offer (the "Offer Period")
             to inform BellSouth whether Predictive wishes to perform and is
             capable of performing the services. During the Offer Period,
             BellSouth shall respond promptly and in good faith to requests by
             Predictive for additional information with respect to the proposed
             Project. If Predictive accepts the Offer within the Offer Period,
             Predictive shall have the right to perform such services as an
             independent contractor to BellSouth. If Predictive rejects such
             offer or fails to accept the same within the Offer Period,
             BellSouth shall have the right to engage another independent
             contractor to perform such Project under the same terms offered to
             Predictive or to perform the same itself.

          b. Attached hereto as Schedule 15.2 is a list of existing and
             potential Predictive customers located within the existing
             BellSouth customer territory. Such customers (and services provided
             by Predictive thereto) shall not be subject to this Addendum.
             Schedule 15.2 shall be updated periodically to reflect changes to
             this customer list, as

                                  CONFIDENTIAL
                                                                     Page 1 of 4

<PAGE>

             obtained by Predictive through its own sales efforts and not in
             violation of this Addendum, subject to the agreement of BellSouth
             which shall not be unreasonably withheld.

          c. Except as set forth herein and in the MPSA, there shall be no
             limitations on the parties' respective activities, including,
             without limitation, their ability to offer independently and for
             their own accounts services marketed jointly by them pursuant to
             this Addendum.

          d. Upon termination of the MPSA this Addendum shall be considered null
             and void. Furthermore, either party may terminate this Addendum at
             any time by providing the other party with thirty (30) days written
             notice of its intent to terminate the Addendum. At this time all
             materials, written and electronic, developed solely by Predictive
             Systems relating to services outlined in Schedule 15.1 must be
             returned to Predictive and BellSouth must refrain from marketing or
             selling Predictive's independently developed methodology. Such
             materials and methodology shall constitute "Information" for
             purposes of the Nondisclosure Agreement ("NDA") dated as of March
             24, 1999, between Predictive and BellSouth. Such materials and
             methodology shall not be included in documents and other materials
             considered to be the property of BellSouth under section 12
             (Proprietary Rights) of the MPSA.

          e. Unless otherwise agreed to in writing by both parties, Predictive
             agrees that any opportunity being jointly pursued by Predictive and
             BellSouth under this Addendum, i.e. any opportunity which is
             subject to a written proposal, will not be pursued by Predictive
             independently. It is further agreed that except for customers
             released as set forth herein, during the term of this Addendum, and
             for six (6) months after the termination of this Addendum,
             Predictive will not pursue any customer introduced to them by
             BellSouth in either a pre-sales effort that resulted in proposed
             work from Predictive or actual services delivered. The parties
             agree to jointly develop and maintain a list of customers that
             Predictive is prohibited from independently pursuing. Such list is
             attached hereto as Schedule 15.3, and shall be updated from time to
             time. At least once per quarter, Predictive and BellSouth will
             review the customer account(s) on Schedule 15.3 to determine
             whether the appropriate activity levels for the sales of Predictive
             services are being met. The criteria for this evaluation should
             include but not be limited to the number of proposed projects and
             the revenue associated with those proposed projects. In the event
             BellSouth and Predictive both agree that the requisite activity
             levels are not being met for the reviewed customer account(s), and

                                  CONFIDENTIAL
                                                                     Page 2 of 4

<PAGE>

             neither party can conceive a solution to increase activity levels,
             BellSouth will release Predictive to pursue business independently
             for the purpose of such account(s). Said agreement and release
             shall not be unreasonably withheld.

          f. For purposes of sections (b) and (e) of this Addendum, the term
             "customer" shall be deemed to refer to the operating or business
             unit as to which the relevant customer decision-maker exercises
             purchasing authority. As a result of the forgoing definition, the
             parties acknowledge and agree that a single entity may contain
             several "customers" for purposes of section (b) and (e) of this
             Addendum.

          Except as expressly modified by this Addendum, the MPSA shall remain
in full force and effect.

         IN WITNESS WHEREOF, this Addendum has been executed BellSouth and
Predictive by their duly authorized representatives.

         the event of any inconsistency between the rates shown in the SOW

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 networks.
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.
