SECTION  3  -  SECURITIES  AND  TRADING  MARKETS
------------------------------------------------

ITEM  3.02  UNREGISTERED  SALES  OF  EQUITY  SECURITIES.

On  September  14,  2004, Tri-Valley Corporation sold 3,425 shares of its common
stock  to one individual purchaser for $13,871 or $4.05 per share, which was the
closing  price of the company's stock on the American Stock Exchange on the date
of sale.  The sale was made in a privately negotiated transaction in reliance on
the  exemption  from the registration requirements of the Securities Act of 1933
(the  "Act")  contained  in  Section  4(2)  of  the  Act.

On July 9 and August 10, 2004,*, the company made two sales of common stock to a
single  individual, also in privately negotiated transactions in reliance on the
exemption  from  registration requirements contained in Section 4(2) of the Act.
On  July  9,  the company sold 300,000 shares of common stock at $4.02 per share
(total  consideration  $1,206,000),  and  on August 10, the company sold 200,000
shares  of  common  stock at $4.01 per share (total consideration $802,000).  In
each  case,  the  price  per  share was equal to the closing market price of the
company's  stock  on  the  American  Stock  Exchange  on  the  date  of  sale.

*  These  two sales were completed prior to the effective date of the amendments
to  Form  8-K  which  adopted  Item  3.02.
