Business ethics are no different than personal ethics.  The same high standard applies to both.  As an employee of Tri-Valley or any of its subsidiaries, you are required to adhere to the highest standard.  The ethical standards set forth in this code reflect who we are and are the standards by which we choose to be judged.

|Misconduct cannot be excused because it was directed or requested by another.  In this regard, you are expected to alert management whenever an illegal, dishonest or unethical act is discovered or suspected.  You will never be penalized for reporting your discoveries or suspicions.  There will be no reprisals for the good faith reporting of a perceived violation.  Reports of a violation will be investigated promptly and the matter will be treated, to the extent possible, as confidential.  In addition to (or instead of) reporting the matter to Tri-Valley's management, employees may report violations by senior management (and must report violations involving financial accounting and reporting) to the chairperson of our audit committee, who is an independent director and who does not report to our president or other senior management of Tri-Valley.

|Any employee who ignores or violates any of Tri-Valley's ethical standards, and any manager who penalizes a subordinate for trying to follow these ethical standards, will be subject to corrective action, including immediate dismissal.  However, it is not the threat of discipline that should govern your actions.  We hope you share our belief that a dedicated commitment to ethical behavior is the right thing to do and is good business.
