Springfield MO  65807 USA

Dear John and Cap,

During our recent conversations, you expressed an interest in developing a
relationship with Muir, Crane & Co. which would provide SLS with strategic
counsel with respect to financial communications as well as assistance in
meeting your corporate finance objectives. The goal of this program is to
generate greater visibility and support of SLS' stock.

Muir, Crane & Co. will implement an outreach program that initially targets the
retail investment community and will arrange meetings with investment bankers
that lead to additional rounds of financing.

It would be our pleasure to work with SLS International to achieve these goals.

MEETINGS W/INVESTMENT BANKERS & OTHER FUNDING SOURCES
-----------------------------------------------------
Muir, Crane & Co. will immediately begin arranging a series of introductory
meetings with appropriate investment bankers and other sources of funding to
secure additional funding. Arranging such meetings will occur concurrently with
the completion of the Benchmark Survey and the White Paper/Corporate Profile.
(See below)

As we discussed in a recent conversation, in our experience, we have the
greatest success rate when we approach this type of project by sequentially
incorporating the following components:

BENCHMARK RESEARCH / INDUSTRY FEEDBACK
--------------------------------------
These studies provide a window into the key issues surrounding the company and
its industry niche. By discussing the SLS model with industry analysts and
investment professionals, we get early reaction and perceptions of the business
model. We will also discover valuable positioning information relating to the
fact that SLS is not a well known entity and the distinguishing characteristics
between SLS and other ultra high fidelity / high-tech consumer retail
investments are available to the market.

As much as this study is a research tool allowing us to determine market
acceptance/resistance, it is also a device that allows us to market the company
to specific targets who invest in companies with similar fundamentals or to key
opinion leaders in the trade, controlled circulation and business press that are
important to your industry niche.

WHITE PAPER / CORPORATE PROFILE
-------------------------------
Similar in look and feel to a research report, but without estimates or
recommendations, the white paper provides an overview of the market and an
overview of the specific opportunity to be exploited by SLS. It provides great
detail as to where SLS fits in to the opportunity, including financial models
discussing ranges of expected revenues and a breakdown of various revenue
steams, as well as outlining the eventual move into broadened product offerings.
This document should also discuss the management team and any specific prior
experience. This is a key component of a highly targeted telephone outreach
program and direct communications campaign.

TRADE MEDIA / LIFESTYLE MEDIA / BUSINESS MEDIA
----------------------------------------------
News articles represent third party validation and provide the materials
necessary to create "Buzz." Successful results from these contacts leads to
reprints that can be redistributed by direct mail to brokers, analysts, and
others within the financial community, as well as to other media contacts.

DIRECT MAIL
-----------
Incorporates staggered mailings of materials crafted to introduce SLS and to
educate targeted audiences to the market opportunity of the company. Feedback
from direct mail identifies qualified prospects for meetings. Materials include
the following:

         1. Introduction Letter with return card
         2. White Paper with positioning cover letter and return card
         3. News article reprints

MEETINGS WITH MICRO-CAP INVESTORS
---------------------------------
Arranged as ether introductory one-on-one conference calls or as scheduled days
of one-on-one or small group meetings with regional retail Broker / Dealers or
Micro-cap money managers. Meetings are often scheduled to take advantage of
pre-existing corporate travel plans. A typical day of meetings would include
four to six meeting s at a cost of $3,000.00 per day.

------------

Co. will be compensated as follows:
