Under the stock trading plan, Dr. Johnson will sell shares over a 13 month
period representing approximately 3.5% of the total shares of II-VI common
stock for which Dr. Johnson is deemed to be the beneficial owner. Dr. Johnson

adopt written plans at times when they are not in possession of material,
non-public information under which they can purchase or sell shares at
predetermined times and price parameters in the future. These pre-planned
trades can then be executed at a later date, as spelled out in the plan,
without further action by the director, officer or other company insider and
without regard to any subsequent non-public information the individual might
have received.
