HARRIS & HARRIS GROUP, INC.

FOCUSES ON BIOLOGY+ IN NEW INVESTMENTS

Shareholders of Harris & Harris Group may be interested to read our latest letter to shareholders, which has been posted to our website at www.HHVC.com, describing our investment focus on BIOLOGY+. BIOLOGY+ is the investment portion of our four-part plan to realize, invest, partner and return over the next five years.  

Harris & Harris Group builds transformative companies from disruptive science. Our investments will have two characteristics: 1) they will be early-stage, where our focus will be on founding, incubating and building transformative companies from disruptive science and 2) they will be focused on BIOLOGY+.

We define BIOLOGY+ as investments in interdisciplinary life science companies where biology innovation is intersecting with innovations in areas such as electronics, physics, materials science, chemistry, information technology, engineering and mathematics. We focus on this intersection because we believe interdisciplinary innovation will be required in order to address many of the life science challenges of the future.

More details on our BIOLOGY+ investment focus can be found in our letter to shareholders at http://ir.hhvc.com/letters.cfm.
