Item 1.01. Entry into a Material Definitive Agreement.

On April 28, 2005, Sutron Corporation amended its 1996, 1997 and 2002 Stock 
Option Plans to make Directors eligible for stock option grants under the 
plans in addition to Officers and key employees.  The plans were also 
amended in regards to the vesting of options.  Previously the options vesting 
schedule required all shares to vest at the rate of twenty percent (20%) 
of the shares on each anniversary of the date of grant of the Option.  This
provision was deleted and replaced with a new provision, that the Board, in 
its sole discretion, will designate the vesting schedule of each individual 
Option that is to be granted.  The 2002 stock option plan was also amended 
to increase the number of shares which may be issued from 400,000 shares 
to 650,000 shares. All stock options issued under the 1996, 1997 and 2002 
Stock Option Plans are Non-Qualified Options.

The Company expects to file the stock option plans, as amended, as exhibits 
to its next Form 10-QSB.
