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

           including, but not limited to, the following:

           7.1.3 Non-availability of resources which are beyond either party's
                 control; and/or,
           7.1.4 Environmental or architectural impediments not previously
                 identified.

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

           7.2.1  The party requesting the change will deliver a change request
                  document ("Change Request") 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.
           7.2.2  A Change Request may be initiated either by the customer or
                  by Cisco 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.
           7.2.3  Upon execution of the Change Request, said Change Request
                  will be incorporated into, and made a part of, this SOW.

     7.3   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.

8.   DURATION OF WORK/SCHEDULE.

     A requested Service commencement date is to be included in Customer's
     Purchase Order subject to confirmation by Cisco.

   12.4.1 Customer acknowledges that, in connection with this Agreement and
          its relationship with Cisco, it may obtain information relating to the

          possession, custody, or control upon termination of this Agreement at
          any time and for any reason. The obligations of confidentiality shall

          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

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 are no conditions, understandings, agreements, representations,
     or warranties, expressed or implied, which are not specified herein.
     This Agreement may only be modified by a written document executed by
     the parties hereto.

        including, but not limited to, the following:

        7.1.1  Customer's changes to the scope of work and/or specifications for
               the Deliverables,

        7.1.2  Customer's changes to the Implementation Plan,

        7.1.3  Non-availability of resources which are beyond either party's
               control; and/or,

        7.1.4  Environmental or architectural impediments not previously
               identified.

    7.2 In the event either party desires to change this Statement of Work, the
        following procedures will apply: 7.2.1 The party requesting the change
        will deliver a change request document ("Change Request") to the other
        party.

        7.2.1  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.

        7.2.2  A Change Request may be initiated either by the customer or by
               Cisco 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.

        7.2.3  Upon execution of the Change Request, said Change Request will be
               incorporated into, and made a part of, this SOW.

    7.3 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.

8.  DURATION OF WORK/SCHEDULE.

    A requested Service commencement date is to be included in Customer's
    Purchase Order subject to confirmation by Cisco.

                 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

                 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

                 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

                 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

       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.

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

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:

                     MASTER PROFESSIONAL SERVICES AGREEMENT

This Master Professional Services Agreement ("Agreement") is effective
this 14th day of May, 1999 and is entered into by and between BellSouth MNS, A
Delaware corporation with a principal place of business at 2400 Century Parkway
("MNS"), Atlanta, GA 30345 and Predictive Systems with offices located at 20
Mansell Court Suite 200 Roswell, GA 30076 ("Client").

1.       Scope of Agreement
This Agreement is intended to be a master agreement under which MNS can place
orders for professional services to be performed by PREDICTIVE SYSTEMS at either
MNS locations or at locations of customers of MNS ("Customers"), in the United
States. MNS and PREDICTIVE SYSTEMS may execute project orders for professional
services under a Statement of Work, a form of which is attached as Exhibit A
("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
remain in effect for two (2) years thereafter unless terminated earlier pursuant
to this Agreement. Provided however, if there is a SOW for which the parties
have obligations that extend beyond such termination date, the terms of this
Agreement shall continue to apply to the SOW until all obligations have been
satisfied.

3.       Independent Contractor
PREDICTIVE SYSTEMS is an independent contractor and nothing in this Agreement or
related to PREDICTIVE SYSTEMS' performance of any SOW shall be construed to
create an employee relationship between MNS and PREDICTIVE SYSTEMS or any
PREDICTIVE SYSTEMS consultant. PREDICTIVE SYSTEMS shall be solely responsible
for (a) payment of applicable taxes, deductions or other payments and benefits
due to or connection with its employees, including, without limitation, federal
and state withholding, social security and unemployment taxes, and any workers'

employment laws, rules and regulations with respect to such employees; and
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.

b. Expenses. MNS will reimburse PREDICTIVE SYSTEMS for pre-approved, reasonable
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".

5.       Warranty
PREDICTIVE SYSTEMS warrants that the Services will be performed in a
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
