On April 10, 2009, Electronic Sensor Technology, Inc. (the "Registrant")

bearing an interest rate of 9% with a maturity of one year. The debenture grants
Halfmoon Bay a security interest in all of the intellectual property of the
Registrant.

Halfmoon Bay currently owns approximately 55% of the outstanding common stock of
the Registrant and beneficially owns an additional 10% of the outstanding common
stock of the Registrant by virtue of the shares underlying a 9% convertible
debenture issued by the Registrant to Halfmoon Bay on March 28, 2008.

A copy of the 9% debenture issued to Halfmoon Bay on April 10, 2009 is attached
hereto as Exhibit 4.1 and incorporated herein by reference.

Item 2.03      Creation of a Direct Financial Obligation.

The disclosures in Item 1.01 are incorporated into this Item 2.03 by reference.
Upon the occurrence of certain circumstances, such as default in payment or
bankruptcy of the Registrant, the principal amount of the 9% debenture held by
Halfmoon Bay, and any interest thereon, become immediately due and payable in
cash.
