ITEM 3.01. FAILURE TO SATISFY A CONTINUED LISTING RULE OR STANDARD

Consistent with Nasdaq procedures, Sutron Corporation reported to The "Nasdaq"
Stock Market on June 27, 2007 that Thomas R. Porter, an independent director and
chairman of the audit committee, passed away unexpectedly of a heart attack on
May 23, 2007 and that, accordingly, the Company no longer technically complies
with Nasdaq's independent director and audit committee requirements as set forth
in Nasdaq Marketplace Rule 4350.

On June 28, 2007, Nasdaq replied via letter to the Company that consistent with
Marketplace Rules 4350(c)(1) and 4350(d)(4), the Company has a cure period in
order to regain compliance with the independent director and audit committee
requirements as set forth in Nasdaq Marketplace Rule 4350. The cure period is
(1) until the earlier of the Company's next annual shareholders' meeting or May
23, 2008; or (2) if the next annual shareholders' meeting is held before
November 19, 2007, then the Company must evidence compliance no later than
November 19, 2007. If the Company does not comply within the cure period, the
Company's stock will be delisted. It is the Company's intent to appoint a new
independent director and otherwise comply with the Nasdaq rules within the cure
period.
