ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On December 22, 2005, the Board of Directors of Sutron Corporation ("the
Company") approved accelerating the vesting of all currently unvested stock
options awarded to employees, officers and directors under its stock option
plans. The closing stock price on of the Company's common stock on December 21,
2005, the last trading day before the acceleration, was $7.50. The unvested
options to purchase up to approximately 254,000 additional shares became
immediately exercisable as a result of the vesting acceleration. Typically,
stock options granted by the Company vest over a five year period. The number of
shares and exercise prices of the options subject to the acceleration remain
unchanged.

The purpose of the accelerated vesting was to enable the Company to avoid
recognizing in its statement of operations non-cash compensation expenses
associated with these options in future periods, upon the expected
implementation of FASB Statement of Financial Accounting Standards No. 123
(Revised 2004), "Share-Based Payment" in January 2006. As a result of the
acceleration, the Company expects to avoid recognition of up to approximately
$2.7 million of compensation expense over the course of the original vesting
periods. Up to approximately $1.1 of such compensation expense is expected to be
avoided in 2006.

Also on December 22, 2005, the Board of Directors of Sutron Corporation approved
a compensation plan for its independent directors. The plan provides that each
independent director shall be paid an annual retainer through a grant of stock
options in the amount of 5,000 shares of common stock of Sutron Corporation that
will vest over a one year period from the date of grant which will be the date
of the Annual Shareholders Meeting. The grant date for 2005 stock options will
not be retroactive to the June 1, 2005, the date of the 2005 Annual
Shareholder's Meeting, but shall become effective as of December 22, 2005 and
the options vest immediately.

Each independent director shall be paid an attendance fee in cash of $1,500 for
each meeting of the Board of Directors where the director is physically present
and in cash of $500 for each meeting attended telephonically. Also, each
independent director shall be paid an attendance fee in cash of $1,000 for each
committee meeting of the Board of Directors where the director is physically
present and in cash of $500 for each meeting attended telephonically. There
shall be no additional compensation when the committee meeting is held in
conjunction with a Board meeting. Travel expenses will be reimbursed at actual
cost.

Finally, the Chairman of the Audit Committee shall be paid in cash an additional
$2,000 for increased responsibility and work required under recently adopted
rules and regulations of the Securities and Exchange Commission.
