                Poly-Scientific / Lumenon [**] Development Plan

INTRODUCTION

In early 2001, Poly-Scientific and Lumenon began working together to develop a
[**]. It was known at that time that 2x2 switches were being used in conjunction
with [**]. The [**]. These components allow [**]. Any change to the [**].

Lumenon, being a manufacturer of MUXES and DEMUXES, was looking for a switch
partner and Poly-Scientific, being a manufacturer of MEMS switches, was looking
for a MUX/DEMUX partner. A MOU was signed to allow work to begin. It was known
at that time that equipment manufacturers were asking for the following:

     - Lower component cost

     - Higher levels of component integration

     - Smaller component packages that translate to smaller board areas

     - Smaller boards that translate to smaller equipment enclosures, etc.

     - All of the above without sacrificing performance

Poly-Scientific/Lumenon's design goal is to create a [**] is currently being
used as an example of what can be done. The following is our design philosophy:

     - Develop [**]
     - Design [**]
     - [**] where possible
       - [**]
       - [**]
       - [**]

illustration of what can be achieved when [**] are used and [**]. Figure 3 shows
all of the [**] on a [**].

PRODUCT DEVELOPMENT AND PROTOTYPING EFFORT

The modules [**] are identified in Exhibit B. The modules that [**] are
identified in Exhibit C. Specifications for each of these products are included
as Exhibit D.

During the past year, major effort has been directed toward the packaging of
each of these modules. In some cases, packages that were being used for a
particular component were changed to fit the overall requirements of the [**].
In other cases, packages were designed to accommodate [**] have been developed.
[**] on a [**] and it is believed that there is [**]. This [**] product were
[**] in some cases [**] have been received, [**] of this product.

While the [**] will be [**] that has been [**].

In Lumenon's case, [**]. [**] are currently being worked. It is anticipated that
[**] will be [**].

Poly-Scientific has [**] is to [**]. It is anticipated that [**] will be [**]
have been [**]and have been [**].

Poly-Scientific is [**] with Lumenon and is [**] [**] will be performed [**] on
the final product.

The date [**] should be completed such that [**] can be made available [**].
