The text of the Letter follows:

Dear Shareholders:

I am pleased to provide this year-end summary of our accomplishments in
2010 and our strategic initiatives moving forward in 2011.

During the past 12 months, we focused our attention on building the
financial, product and infrastructure foundations for our future growth.
Specifically, several key milestones were achieved, including the:

    - Successful closing of our initial round of financing in excess of $6
    million;

    - Securing of the first two orders for our Krystall ( tm ) water
    purification units and signing of distribution agreements for such units
    in Algeria and Malaysia;

    - Undertaking of two major new business market studies which validated
    our products and the market's need for them;

    - Identification of third-party leasing sources ready to commit to
    financing Krystall purchases by the public and private sectors;

    - Building of an enlarged production platform and infrastructure for
    Krystall to accommodate anticipated sales growth;

    - Addition of personnel in sales, marketing and technical support;

    - Move to new headquarters in the prestigious R&D Science Park at EPFL,
    further expanding our special relationship with LESO, the solar applied
    research laboratory of EPFL; and

    - Invitation to be an "official observer" at the UN Convention on Climate
    Change in Cancun, a sponsor of the World Climate Summit and an exhibitor
    at the Green Solutions trade show.

In 2011, we are moving ahead aggressively to become an established
world-wide provider of advanced solar-powered technologies in the areas of
water purification and the cooling/heating of buildings. The hard work
undertaken during 2010 is already paying off in these first few days of 2011:

    - We are in negotiations with several entities for the sale of a
    significant number of Krystall units;

    - Studies are underway in preparation for bidding on major infrastructure
    projects using Klymaa's ( tm ) cooling and heating technology;

    - There continues to be active interest in the company from several major
    investment groups; and

    - We are in advanced discussions with a major Asian global construction
    conglomerate for a joint venture in that part of the world.

I will be coming back to you shortly with more updates.

We believe that we have the right products at the right time, and we look
to 2011 with great excitement.

Thank you for the confidence you have shown in SwissINSO. On behalf of
Management and the Board of Directors, all best wishes for a healthy and
prosperous new year.

Michel Gruering
