                              Goals and Objectives

2.1  General:

The business relationship between NCS and SmarterKids.com is a focused priority
on providing value-added electronic testing and educational products and
services to our clients and their constituents in the K-12 market. The theme of
the business proposition is to augment state assessment programs by offering a
variety of HelpTests for users to access on-line. These tests will provide
feedback on student skill proficiency and performance. Using this skill data,
NCS will refer parents/teachers to recommended web sites where they may find
educationally relevant information, services, and products (SmarterKids.com).

2.2  On-line HelpTests:

The purpose of the NCS web site is to provide HelpTests aligned specifically to
individual state assessment standards and curriculum requirements.  Additionally
off-grade tests and national tests (e.g., NAEP items) will also be provided
online.  These tests will promote confidence in test taking skills, provide an
early assessment of student strengths and areas for improvement, an electronic
workbook for repeat test takers working to pass state matriculation standards,
and provide educational product recommendations for skill proficiency
improvement (SmarterKids.com). Additionally, the site will accommodate direct
entry of individual student report data for parents/teachers whose children have
already taken a state assessment test.

It is not planned that a paper-based HelpTest would be provided as part of this
project.

[CONFIDENTIAL TREATMENT REQUESTED]**

2.3  Link To SmarterKids.com:

At the completion of a HelpTest, the student scores and results are provided on-
line.  The user will be referred to options, including "Would You Like To See
Products and Services Tailored To: 1) Concentration On Strengths 2)
Concentration On Areas For Improvement." After a selection, a Notice page will
advise the user of linking to SmarterKids.com for product recommendations.

The user will arrive at the SmarterKids.com web site, with special co-site
branding of NCS and SmarterKids.com and navigation button(s) back to NCS.  This
will promote intersite navigation and will build the brand recognition,
confidence, and quality of our relationship.

                                 Project Plans

3.1  Pilot Projects:

NCS has identified two state pilot projects to kickoff the initiative.  One
pilot will be a statewide initiative for Michigan and the [CONFIDENTIAL
TREATMENT REQUESTED]**.  For participating in the pilot projects, NCS will
provide a special promotional offer of [CONFIDENTIAL TREATMENT REQUESTED]** and
a [CONFIDENTIAL TREATMENT REQUESTED]** merchandise credit at the SmarterKids.com
web store.  This discount could be applied to teacher accounts and/or Title I
district funds.  Participation by states in the pilot projects is subject to
their approval.

3.2  Project Phases:

This project will be divided into three phases.

Phase 1 will involve the generation of a PC based demonstration tool and
marketing materials to initiate discussions with customers to promote support
for hosting a pilot project.  This system will include an alpha release of the
WeHelpKids.com web site including menus and links, (1) 30Q Math Grade 4
HelpTest, test skill results mapping to SmarterKids.com skill sets, and the
process of linking to the SmarterKids.com web site for product recommendations.

Phase 2 will involve the active deployment of a beta WeHelpKids.com web site to
support both the Michigan and [CONFIDENTIAL TREATMENT REQUESTED]** pilots.  NCS
will provide a subset of HelpTests and ReportCard entry forms for inputting
state test results.  Skill results from the HelpTest and ReportCard will be
completely mapped to SmarterKids.com skill sets.  The user will then be windowed
to the SmarterKids.com site for product recommendations.

Phase 3 will involve a postmortem analysis of the pilot projects and their
contribution to the NCS/SmarterKids.com value proposition.  Collected
information such as demographics, purchasing profile, adoption rates, revenue
models, customer reactions, and other meaningful market data will be assessed to
help refine the parameters of the business relationship.  At the conclusion of
this phase, a Go/No Go decision will be made on a nationwide deployment of this
initiative.

3.3  Project Tasks and Schedule:

The project tasks and planned schedule associated with completion of the Phases
1 through 3 are shown in the attached project schedule:

                               Value Proposition

5.1  Revenue Model:

The revenue from this initiative will result from the purchase of products and
services at SmarterKids.com by parents/teachers. For state participation in the
pilot projects, NCS will provide a special promotional offer of [CONFIDENTIAL
TREATMENT REQUESTED]**, and a [CONFIDENTIAL TREATMENT REQUESTED]** merchandise
credit at the SmarterKids.com web store. This discount will be applied to
special teacher accounts and/or donations to Title/district funds, as
applicable.

It is envisioned that providing the HelpTest service for free will maximize
traffic to the NCS web site, and ultimately maximize the exposure and adoption
rate of products on the SmarterKids.com site. However, these pilot projects may
validate the possibility of ultimately charging a registration fee for the
HelpTest on the NCS web site.

5.2  Financial Model:

     1. Standard Affiliate Program:  Revenue generated from clients linking
        from the NCS web site to the SmarterKids.com store. Each and every time
        a client links from NCS to SmarterKids.com and purchases products, NCS
        will receives [CONFIDENTIAL TREATMENT REQUESTED]** of the gross margin
        of all SmarterKids.com sales to that client.

     2. Special Affiliate Program:  Revenue generated from clients returning
        directly to the SmarterKids.com store through a special SmarterKids.com
        homepage especially designed for NCS and its customers. (e.g.,
        http://www.smarterkids. com/whk). Each and every time a client enters
        this homepage and subsequently purchases products, NCS receives
        [CONFIDENTIAL TREATMENT REQUESTED]** of the gross margin of all
        SmarterKids.com sales to that client.

     3. Special Coupon Program: Revenue generated from clients returning
        directly to the SmarterKids.com store and purchasing products using
        special NCS incentive codes. Each and every time a client purchases
        products and enters a special NCS code, NCS receives [CONFIDENTIAL
        TREATMENT REQUESTED]** of the gross margin of all SmarterKids.com sales
        to that client.

                           Value Proposition (Cont.)

5.3  Margin Calculation:

Gross margin will be defined as the net revenue of the sale of products less the
cost of goods sold for those products:

Net revenue shall be defined as the gross revenue on the sale of all products
less any discounts, applicable promotions, merchandise incentive program
discounts or other programs that reduce the cost of the product to the customer.
Shipping and sales tax are excluded from the calculation.

Cost of Goods shall be defined as the cost of the product to SmarterKids.com, as
charged by our 3/rd/ party fulfillment partner.  These costs consist of the
purchase cost from the product manufacturer plus handling and fulfillment fees
incurred by our fulfillment partner.  Additionally, royalties to the content
providers of proprietary SmarterKids.com products (the Children's Skills Test
line) shall be an additional cost of goods on those items only.  Freight-out
costs are excluded from the calculation.

5.4  Terms of Payment:

Payment to NCS under this agreement shall occur quarterly, 30 days following the
close of each calendar quarter.

5.5  Audit:

NCS shall have the right to perform (or have performed on its behalf) an audit
of the books and records (including business records and web site activity
records regardless of media) of SmarterKids.com, relating to the performance of
SmarterKids.com's obligations under this Agreement and the calculation of all
payments due to be paid to NCS hereunder. Such audits shall be conducted at
reasonable times and frequencies, with a minimum advanced notice of 10 business
days, during regular business hours and subject to the terms and condition of
the Non-Disclosure Agreement referred to in Section 4.8.

5.6  Purchase Incentives:

SmarterKids.com offers NCS, on a nonexclusive basis, a merchandise incentive
program. This incentive program allows NCS to offer merchandise credits to its
clients for purchasing products at the SmarterKids.com web store using methods
described in Section 5.2. These credits may be applied to teacher or other
special accounts at the rate of [CONFIDENTIAL TREATMENT REQUESTED]** of sales
price. NCS and SmarterKids.com shall equally share the cost burden of a client
exercising a merchandise credit.

                           Value Proposition (Cont.)

5.7  Stock Warrants:

Smarterkids.com will grant to NCS, with the approval of the SmarterKids.com
Board Of Directors, warrants to purchase 75,000 shares (approximately 1.00% of
the company post financing) of the Company's common stock at an exercise price
of $2.00/share. These shares would be exercisable in four equal increments based
on completion of the planned rollout to states (to be mutually agreed upon). One
fourth would be immediately exercisable upon completion of phase three and a
"Go" decision on large scale deployment of the state initiatives. The remaining
warrants would be exercisable as completion of the rollout occurs.
