Item 1. Business.

     In this annual report, references to the "company," "we," "our," or "us"
refers to Electronic Sensor Technology, Inc., a Nevada corporation.

     We are engaged in the development, manufacture, and sale of a patented
product we call zNose(R), a device designed to detect and analyze chemical odors
and vapors, or, in another words, an electronic "nose". We believe the zNose(R)
is superior to other electronic "noses" because of its speed, specificity and
sensitivity. The zNose(R) identifies the chemical makeup of any fragrance, vapor
or odor. The zNose(R) does this by creating a visual image of the fragrance,
vapor or odor that it detects, so that the user of the zNose(R) may easily
identify the fragrance, vapor or odor.

     We believe that our products have broad applications in the homeland
security, analytical instrumentation/quality control, and environmental
monitoring and detection markets. We are involved in ongoing product research
and development efforts in that regard. We have also concentrated our efforts on
further product development, testing and proving, and continuing to expand our
sales and support organization.

     Our executive offices are located at 1077 Business Center Circle, Newbury
Park, California 91320 and our telephone number is (805) 480-1994.

HISTORY AND BACKGROUND

     Electronic Sensor Technology, Inc. was originally incorporated under the
laws of the state of Nevada as Bluestone Ventures Inc. on July 12, 2000. From
the date of its incorporation until February 1, 2005, Bluestone Ventures was in
the business of acquiring and exploring potential mineral properties in Ontario,
Canada. The company's name was changed to "Electronic Sensor Technology, Inc."
on January 26, 2005 in connection with the acquisition of two corporations that
had together owned Electronic Sensor Technology, L.P. Since the acquisition of
Electronic Sensor Technology, L.P., our business has been the development,
manufacture and sale of instruments that detect and analyze vapors and odors.
The company has abandoned its mining exploration business.

Overview of Past Operations of Electronic Sensor Technology, L.P.

     Electronic Sensor Technology, L.P. was formed in 1995 to develop and
manufacture, the zNose(R), an advanced technology in chemical vapor detection
and analysis. In 1999, Electronic Sensor Technology, L.P. completed beta testing
of its products and commenced commercial sales to the analytical
instrumentation/quality control market as well as the homeland security market.

Electronic Sensor Technology, L.P. Acquisition

     On February 1, 2005, pursuant to the terms of an Agreement and Plan of
Merger by and among Electronic Sensor Technology, Inc., Amerasia Technology,
Inc., holder of approximately 55% of the partnership interests of Electronic
Sensor Technology, L.P., L&G Sensor Technology, Inc., holder of approximately
45% of the partnership interests of Electronic Sensor Technology, L.P., Amerasia
Acquisition, a wholly-owned subsidiary of Electronic Sensor Technology, Inc.,
and L&G Acquisition, a wholly-owned subsidiary of Electronic Sensor Technology,
Inc., Electronic Sensor Technology, Inc., acquired 100% of the outstanding
equity partnership interest of Electronic Sensor Technology, L.P. Under the
Agreement and Plan of Merger:

     (i)  Amerasia Technology merged with and into Amerasia Acquisition such
          that Amerasia Technology became a wholly-owned subsidiary of
          Electronic Sensor Technology, Inc.;

     (ii) L&G Sensor Technology merged with and into L&G Acquisition such that
          L&G Sensor Technology became a wholly-owned subsidiary of Electronic
          Sensor Technology, Inc.;

     (iii) as a result of the mergers of (i) and (ii), Electronic Sensor
          Technology, Inc. indirectly acquired the partnership interests of
          Electronic Sensor Technology, L.P.; and

     (iv) Electronic Sensor Technology, Inc. issued 20,000,000 shares of its
          common stock to the shareholders of Amerasia Technology and L&G Sensor
          Technology.

     In November 2004, Electronic Sensor Technology, L.P. sold $200,000 in
limited partnership interests to certain bridge investors. Concurrent with the
mergers, these limited partnership interests were directly exchanged into
200,000 shares of common stock of Electronic Sensor Technology, Inc. and
warrants to purchase 200,000 shares of common stock of Electronic Sensor
Technology, Inc. at $1.00 per share.

     In connection with the mergers, Electronic Sensor Technology, Inc. entered
into Subscription Agreements with certain investors on January 31, 2005. Under
these Subscription Agreements, Electronic Sensor Technology issued and sold in a
private placement 3,985,000 shares of its common stock and warrants to purchase
3,985,000 shares of common stock at $1.00 per share to certain investors for
gross proceeds of $3,985,000, which were received on February 1, 2005.
Electronic Sensor Technology received net proceeds of approximately $3,821,000
less fees, including counsel fees for the investors and Electronic Sensor
Technology, L.P. of approximately $164,000.

     Immediately following the mergers and the private placement, on February 1,
2005 there were 53,968,471 shares of Electronic Sensor Technology common stock
outstanding, of which (i) shareholders of Bluestone Ventures prior to the
mergers and the private placement held 26,988,279 shares (approximately 50.0% of
our common stock), (ii) the shareholders of Amerasia Technology and L&G Sensor
Technology prior to the mergers and the private placement held 22,783,471 shares
(approximately 42.2% of our common stock) and (iii) investors in the private
placement occurring on February 1, 2005 and the bridge investors as a group held
4,185,000 shares (approximately 7.8% of our common stock). The total outstanding
interests of Electronic Sensor Technology, L.P. were exchanged for 20,000,000
shares of Electronic Sensor Technology, Inc. In addition, 2,783,279 shares of
Electronic Sensor Technology, Inc. were distributed to pre-merger shareholders
of Amerasia Technology and L&G Sensor Technology in exchange for the
cancellation of debt owed to such shareholders, at a conversion rate of $1.00
per share. The conversion rate of $1.00 per share was established immediately
preceding the merger through the private placement of 3,985,000 shares of common
stock at $1.00 per share and the conversion of a $200,000 equity advance to
Electronic Sensor Technology, L.P. for 200,000 shares of Electronic Sensor
Technology common stock. The transaction price of $1.00 per share was
established by arms length negotiation between the former management of
Bluestone Ventures and Electronic Sensor Technology, L.P. (now management of
Electronic Sensor Technology, Inc.) in December 2004. As a condition to the
merger transactions, Bluestone Ventures agreed to raise not less than $3,000,000
of new equity capital in a private placement offering. In determining to proceed
with the merger transactions, management of Electronic Sensor Technology, L.P.
(now management of Electronic Sensor Technology, Inc.) weighed the expected cash
balance of Bluestone Ventures after giving effect to the private placement
offering discussed above and the mergers against the overall equity ownership of
Electronic Sensor Technology, Inc. post-merger that would be held by the former
owners of Electronic Sensor Technology, L.P. (i.e., the former owners of
Electronic Sensor Technology, L.P. were willing to give up 57.8% of Electronic
Sensor Technology, L.P. for not less than $3,000,000 in cash). While management
of Electronic Sensor Technology, L.P. (now management of Electronic Sensor
Technology, Inc.) was not privy to the valuation methodology used by management
of Bluestone Ventures in establishing a transaction price of $1.00 per

                                        2
<PAGE>
share, management of Electronic Sensor Technology, L.P. (now management of
Electronic Sensor Technology, Inc.) assumes that management of Bluestone
Ventures and its advisors used one or more traditional valuation methodologies.

     Following the mergers we assumed as our principal operations the operations
of Electronic Sensor Technology, L.P. and the prior operations of Bluestone
Ventures were terminated.

INDUSTRY OVERVIEW

     Although there are a vast number of applications for the zNose(R) product,
we believe that the most significant demands for our product will be in three
general market categories - homeland security, analytical
instrumentation/quality control and environmental monitoring and detection.

     Homeland Security. According to published sources, the homeland security
market is a multi-billion dollar market and is projected to remain as such in
the foreseeable future. We believe that detection and analysis of chemical
compounds will aid greatly in various homeland security efforts including:

     o    Cargo Containers. Over 46.3 million cargo containers arrive in the
          U.S. every year and only a fraction of them are being inspected by the
          U.S. Customs Department. We believe cargo container security will
          become a top priority with the U.S. government.

     o    Airports. Our zNose(R) products may be used to complement existing
          x-ray and bomb detection technologies.

     o    Drug Interdiction. The zNose(R)has been used to detect contraband,
          including illicit controlled substances along U.S. borders.

     o    Building Security. zNose(R) technology can be applied for continuous
          and real-time chemical detection and to monitor the air in buildings
          and in confined spaces. Detecting hazardous gases and poisonous
          chemical agents such as sarin, VX explosives, and contrabands for
          security and environmental safety purposes are the main concerns for
          various government and commercial buildings, as well as military
          facilities.

     Analytical Instrumentation/Quality Control. The zNose(R) has been serving
the chemical vapor analysis needs in various manufacturing industries. We
estimate that the market for products such as zNose(R) will exceed $50 million
during the next few years. The zNose(R) has been used for a host of applications
relating to analysis and quality control such as:

     o    screening incoming raw materials;

     o    checking ingredients in processed food and pharmaceutical products;

     o    inspecting packaging materials and finished goods; and

     o    detecting hazardous gas leaks in chemical plants.

     Environmental Monitoring and Detection. The zNose(R) has been serving rapid
on-location needs in detection and monitoring of toxic chemicals in the water
for environmental protection purposes. The zNose(R) was used by the China
Environmental Protection Agency (China EPA) to detect and monitor toxic flows in
a river caused by a chemical spill after a chemical plant explosion in
northeastern China. This industrial accident contaminated the major water
sources located near the plant. The zNose(R) is also used by the China
Environmental Protection Agency (EPA) to determine the safety of drinkable water
on a near real-time basis.

CONVENTIONAL ELECTRONIC NOSE TECHNOLOGY

     Conventional electronic noses are unable to meet the needs of the market
because of their fundamental construction. They are not able to identify
fragrances, vapors and odors with an acceptable degree of specificity and
preciseness. In addition, conventional electronic noses require sophisticated
computer software in order for its chemical analyses to be recognized. This type
of electronic nose is therefore not acceptable for use in scientific
measurement.

                                        3
<PAGE>
THE ZNOSE(R) SOLUTION

     Speed, precision and versatility are the key characteristics of the
zNose(R) product. The zNose(R) has been developed to replace the conventional
electronic nose. The zNose(R) operates as quickly as a conventional electronic
nose while delivering the precision and accuracy of a much more expensive
instrument. The zNose(R) has advanced chemical analysis technology by performing
vapor analysis within 10 seconds. Early models of the zNose(R) have been tested
by the U.S. Environmental Protection Agency under Environmental Technology
Verification program and by the Office of National Drug Control Policy for drug
interdiction. Tests have also been performed at the Midwest Research Institute's
Surety Laboratory in Kansas City and at the U.S. Army Dugway Proving Ground in
Utah with respect to the effectiveness of the zNose(R) in detecting chemical
agents such as sarin gases.

     Our VaporPrint(R) imaging ability is another major advantage of the
zNose(R) product. VaporPrint(R) allows the user of the zNose(R) to see a visual
image of the makeup of a particular fragrance, vapor or odor within 10 seconds.
In addition, VaporPrint(R) can produce high-resolution visual images of odor
intensity. VaporPrint(R) images are displayed on a laptop computer screen and
are recorded on the hard drive of the laptop computer.

OUR PRODUCTS

zNose(R)

     The zNose(R) is essentially a vapor detector that uses a sensor based on
Surface Acoustic Wave technology. Basically, the zNose(R) "inhales" a particular
fragrance, vapor or odor. The fragrance, vapor or odor is carried up through a
column and the chemicals making up the fragrance, vapor or odor condense on the
crystal surface of the sensor in the zNose(R). This condensation on the sensor
causes a change in what is called the "fundamental acoustic frequency" of the
crystal surface. It is this change in fundamental acoustic frequency that allows
the zNose(R) to determine the chemical makeup of the fragrance, vapor or odor.
This change is measured by a microprocessor that calculates the change in
frequency which is related to the amount of fragrance, vapor or odor sampled by
the zNose(R). The microprocessor also measures the arrival time (called the
retention time) of the change in the fundamental frequency. Different chemicals
arrive at different times and so, once the microprocessor has determined the
retention time of the unidentified fragrance, vapor or odor, it compares it to
retention times that are stored in a computer library. This allows the zNose(R)
to identify the particular fragrance, vapor or odor.

     The zNose(R) analyzes and identifies vapor specimens in a two-step process.
In the first step, typically lasting 10 seconds, the instrument collects a small
sample of the vapor to be analyzed. The sample is then injected in to the gas
chromatography column where the individual chemicals present are separated and
measured. The chemical analysis requires as little as 10 seconds to produce the
vapor's chemical signature, or chromatogram. The vapor's chemical signature can
also be visually displayed in a graphic form called a "VaporPrint". This
chemical signature is then compared against the reference database of chemical
odor profiles. If the chemical compound of the specimen is not in the reference
database, it will not be identified by name; however, the makeup of the
unidentified specimen can be stored in the reference database for future
identification. The reference database of chemical odor profiles that is stored
on the hard drive of the laptop computer is composed of standards of various
chemicals that are available through the National Institute of Standards and
Technology (NIST). The database can be updated when standards of new chemicals
are encountered and input by way of simple software selection, or by way of
sampling unknown chemical compounds and storing the measurements of such
chemical compounds in the database. If the zNose(R) samples a non-specimen
vapor, such as clear ambient air, no signal is generated on the laptop computer
screen and no VaporPrint(R) is created. If the zNose(R) samples a complex
mixture of chemical compounds, each compound and the concentration of such
compound is measured independently of the other compounds contained in the
mixture. Due to the independent measurement of each compound in a complex
mixture, each measurement is free from the influence of the other compounds, and
the accuracy of the zNose(R) is therefore not affected by complex mixtures.

     We currently manufacture and sell four zNose(R) models designated as Model
4200 (Handheld Unit), Model 4300 (Portable Unit), Model 7100 (Bench Top Unit),
and Model 8100 (Fixed Installation Unit). Model 4200 is designed for portability
and for applications requiring quick and accurate vapor screening in the field.
Model 4300 is also designed for portability and can operate outdoors with the
same capabilities of Model 4200 without the need for an external power source.
Model 7100 is designed for laboratory testing and is ideal for testing water and
product quality control samples. Model 8100 is designed for indoor ambient air
monitoring and can be used for building security monitoring applications. Both
Model 4200 and Model 7100 weigh approximately 27 pounds, not including a laptop
computer that must be used with each zNose(R). Model 4300 weighs approximately
24 pounds, not including the laptop computer, but also includes a battery
charger that weighs approximately 8

                                        4
<PAGE>
pounds. The Model 4200 has two housings (the case and the detector head) and a
laptop computer. The case of the Model 4200 is 10" x 12" x 6" and weighs 20
pounds and the detector head of the Model 4200 is 4.25" x 12" x 7" and weighs 7
pounds. The components and dimensions of the Model 4300 are similar to the Model
4200, but the battery charger of the Model 4300 is 5.5" x 13.5" x 5.5. The Model
7100 is packaged in a single housing and also requires a laptop computer. The
dimensions of the Model 7100 packaging are 14.3" x 14.3" x 7.5". The Model 8100
is designed as a fixed installation unit for indoor ambient air monitoring and
is designed to be operated remotely from a central control station via a
Bluetooth control link. The dimensions of the Model 8100 unit are 15" x 37" x
36". The Models 4200, 7100, and 8100 are powered by a standard AC electrical
outlet, and all models adapt to standard outlets in North America, Asia and
Europe (i.e., the zNose(R) may be operated by a 110 volt or 220 volt power
source). All four models can be produced in one of two basic vapor sensing
configurations: volatile and semi-volatile. The volatile configuration can
detect volatile organic compounds, such as benzene. The semi-volatile
configuration can detect heavier vapors such as those found in explosives and
drugs.

     During 2008, we developed the Model 4500. The Model 4500 is a two-piece
portable unit that is similar in configuration to the Model 4300 except for the
laptop computer that is required by the Model 4300 has been replaced by an
embedded processor in the Model 4500.

Accessories

     We offer several lines of accessory products such as calibration devices,
sample desorbers, MicroSense Software(C), and GPS receivers. An example is our
Model 3100 which provides a calibrated vapor source as well as a tool for
extracting vapors from solid and liquid samples.

COMPETITION

     We are unaware of any direct competitor to the zNose(R) product on the
market today. In the homeland security markets, we face competition from
manufacturers of x-ray machines, ion-mobility spectrometers and chemical coated
sensors. X-ray machines have been widely used for security purposes in detecting
metal objects but not for chemical compounds. Ion-mobility spectrometer
equipment is a vapor detector and is designed to detect certain compounds but is
blind to other compounds. Hence, it can only see a small dot in a space but
cannot see the total picture. It employs a different sample collection technique
by wiping the surfaces of the object placed for screening. The ion-mobility
spectrometer also uses materials in its construction which may be offensive to
users in certain countries.

     Chemical coated sensors are the conventional electronic noses. They use an
array of chemical sensors each reacting to certain specific compounds. As
mentioned earlier, electronic noses cannot be calibrated with chemical standards
and therefore cannot be used effectively for scientific measurement.

     We have another set of competitors manufacturing portable vapor and odor
analysis products for the instrumentation market from major corporations such as
Agilent Technologies, Inc. (NYSE: A), Perkin-Elmer, Inc. (NYSE: PKI) and Varian,
Inc. (NASDAQ: VARI). We believe that our zNose(R)product is competitive with
these companies' products based on speed and cost.

     Many of our current and potential competitors, including the aforementioned
competitors, have larger customer bases, greater brand recognition and
significantly greater financial, marketing and other resources than we do and
may enter into strategic or commercial relationships with larger, more
established companies. Some of our competitors may be able to secure alliances
with customers and affiliates on more favorable terms, devote greater resources
to marketing, advertising and promotional campaigns and devote substantially
more resources to research and development than we do. In addition, new
technologies and the expansion of existing technologies may increase the
competitive pressures on us.

     We cannot assure you that we will be able to compete successfully against
current or future competitors, and competitive pressures faced by us could harm
our business, operating results and financial condition. We do not currently
represent a significant competitive presence in the homeland security or
analytic instrumentation markets.

MANUFACTURING AND RAW MATERIALS

     We design, prototype and manufacture our products at our headquarters. Our
manufacturing facilities adhere to ISO9001 manufacturing methods (quality
standards developed by the International Organization for Standardization, which
have been adopted by many countries around the world). We contract out the
manufacturing and assembling of certain components to subcontractors. Our
current annual manufacturing capacity is approximately 300 zNose(R) units. The
principal components to our products are computer chips, circuit boards,
transformers and sensory devices. The prices for these components are subject to
market forces largely beyond our control, including energy costs, market demand,
and freight costs. The prices for these components have varied significantly in
the past and may vary significantly in the future. Our principal suppliers of
components and raw materials include: Sigma Aldrich Co. of Bellefonte,
Pennsylvania, American Precision of Chatsworth, California, Machine Works LLC of
Santa Paula California, Clayton Controls of Costa Mesa, California, and Syncor
Industries, Inc. of Ventura, California.

CUSTOMERS

     In 2008, we had approximately 61 customers. Our largest customer in 2008,
Beijing R&D Technology Company Ltd. (which is our exclusive distributor in
China), purchased 22 of the total 56 zNose(R) units sold by us in 2008,
constituting approximately 39% of the zNose(R) units sold in 2008. Our largest
customers are (1) Beijing R&D Technology Company Ltd. of China, (2) Petroleum
Services Co. and (3) Security Pro USA.

PATENTS, TRADEMARKS AND OTHER PROPRIETARY RIGHTS

     We regard our patents, trademarks, trade names and similar intellectual
property as critical to our success. We rely on patent and trademark laws, trade
secret protection and confidentiality agreements with employees, distributors,
customers, partners and others to protect our proprietary rights.

     We own four United States patents covering our zNose(R) product, including:

     o    No. 5,289,715, "Vapor Detection Apparatus and Method Using an Acoustic
          Interferometer" issued March 1, 1994;

     o    No. 5,970,803, "Method and Apparatus for Identifying and Analyzing
          Vapor Elements", issued October 26, 1999;

     o    No. 6,212,938, "Method of Detecting Smell of a Vapor and Producing a
          Unique Visual Representation thereof," issued April 10, 2001;

     o    No. 6,354,160, "Method and Apparatus for Identifying and Analyzing
          Vapor Elements," issued December 3, 2002.

                                        6
<PAGE>
     We may not be able to obtain patent protection for any derivative uses of
zNose(R), or for any other products we may later acquire or develop. We also
cannot assure you that we will be able to obtain other foreign patents to
protect our products.

     We have copyrighted our MicroSense Windows software and Xilinx gate array
firmware, which controls the operation of the zNose(R) and produces visual
images. These images, trademarked as VaporPrint(R) images, make it possible to
display vapor analysis data from any vapor analysis system, as unique visual
images and facilitate pattern recognition of complex odors and fragrances.

     We currently hold registered trademarks for zNose(R) and VaporPrint(R). We
intend to evaluate the possible application for new patents and trademarks as
needed to cover current and future applications of our technology and product
developments. We intend to undertake all steps necessary to preserve and protect
our patents, trademarks and intellectual property generally.

     We are not aware that our products, trademarks or other proprietary rights
infringe the rights of third parties, nor are we aware of any infringements of
our proprietary rights. We continually evaluate potential infringements of our
proprietary rights and intend to take such legal and other actions as may be
necessary to protect those rights. However, there can be no assurance that third
parties will not assert infringement claims against us in the future with
respect to current or future products or that any such assertion may not require
us to enter into royalty arrangements or result in costly litigation.

GOVERNMENT REGULATION

     Government agencies, in particular, the Department of Defense, are
principal customers for our products. As a result, we are required to comply
with the Federal Acquisition Regulations, a comprehensive set of regulations
governing how vendors do business with the U.S. federal government, to the
extent we contract with departments or agencies of the U.S. government, as well
as similar regulations to the extent we contract with state or local
governments. Sales to or grants from foreign governments or organizations
generally have their own regulatory framework, which may or may not be similar
to present U.S. standards or requirements.

RESEARCH AND DEVELOPMENT

     Our research and development program consists of developing technologies
related to enhancing our electronic nose product and making it more portable.
Fees related to research and development include consulting fees, technical
fees, and research, development and testing of our zNose(R) product. We spent
approximately $745,000 in 2007 and $658,000 in 2008 on research and development
activities, none of which was borne directly by customers.

EMPLOYEES

     As of December 31, 2008 we had a total of 15 full-time employees and 3
consultants. In addition to management, we employ sales people, administrative
staff, and development and technical personnel. From time to time, we may employ
independent consultants or contractors to support our research and development,
marketing, sales and support, and administrative organizations. No collective
bargaining units represent our employees and Electronic Sensor Technology is not
party to any labor contracts.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

     You should read the following discussion and analysis of our financial
condition and results of operations together with the financial statements and
the related notes appearing in this annual report.

CRITICAL ACCOUNTING POLICIES

     Electronic Sensor Technology records revenue from direct sales of products
to end-users when the products are shipped, collection of the purchase price is
probable and Electronic Sensor Technology has no significant further obligations
to the customer. Costs of remaining insignificant obligations of Electronic
Sensor Technology, if any, are accrued as costs of revenue at

                                       10
<PAGE>
the time of revenue recognition. Cash payments received in advance of product
shipment or service revenue are recorded as deferred revenue.

     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the recorded amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     Electronic Sensor Technology reviews long-lived assets, such as property
and equipment, to be held and used or disposed of, for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. If the sum of the expected cash flows, undiscounted and
without interest, is less than the carrying amount of the asset, an impairment
loss is recognized as the amount by which the carrying amount of the asset
exceeds its fair value. At December 31, 2008 no assets were impaired.

     The company accounts for its liquidated damages pursuant to FASB Staff
Position No. EITF 00-19-2 "Accounting for Registration Payment Arrangements"
("FSP 00-19-2"). FSP 00-19-2 provides that the contingent obligation to make
future payments or otherwise transfer consideration under a registration payment
arrangement, should be separately recognized and measured in accordance with
FASB Statement No.5, "Accounting for Contingencies". The registration statement
payment arrangement should be recognized and measured as a separate unit of
account from the financial instrument(s) subject to that arrangement. If the
transfer of consideration under a registration payment arrangement is probable
and can be reasonably estimated at inception, such contingent liability is
included in the allocation of proceeds from the related financing instrument.
The company had registered all shares underlying the 8% convertible debentures
as well as all shares underlying the warrants related to the 8% convertible
debentures, but no longer maintains such registration, in light of the partial
conversion and partial cancellation of the debentures and a portion of the
warrants.

     The company accounts for its embedded conversion features and freestanding
warrants pursuant to SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities", which requires a periodic valuation of their fair value and
a corresponding recognition of liabilities associated with such derivatives. The
recognition of derivative liabilities related to the issuance of shares of
common stock is applied first to the proceeds of such issuance, at the date of
issuance, and the excess of derivative liabilities over the proceeds is
recognized as other expense in the accompanying consolidated financial
statements. The recognition of derivative liabilities related to the issuance of
convertible debt is applied first to the proceeds of such issuance as a debt
discount, at the date of issuance, and the excess of derivative liabilities over
the proceeds is recognized as other expense in the accompanying consolidated
financial statements. Any subsequent increase or decrease in the fair value of
the derivative liabilities, which are measured at the balance sheet date, are
recognized as other expense or other income, respectively.

     Accounts receivable are reported at net realizable value. We have
established an allowance for doubtful accounts based upon factors pertaining to
the credit risk of specific customers, historical trends, and other information.
Delinquent accounts are written-off when it is determined that the amounts are
uncollectible.

     Inventories are stated at the lower of cost or market, cost determined by
the first-in, first-out (FIFO) method. The company writes down its inventory for
estimated obsolescence or unmarketable inventory using the difference between
the cost of inventory and the estimated market value based upon assumptions
about future demand and market conditions.

     We are required to estimate our income taxes in each of the jurisdictions
in which we operate as part of the process of preparing our consolidated
financial statements. SFAS No. 109, "Accounting for Income Taxes", requires a
valuation allowance to reduce the deferred tax assets reported if, based on the
weight of the evidence, it is not more likely than not that some portion or all
of the deferred tax assets will be realized. Management reviews deferred tax
assets periodically for recoverability and makes estimates and judgments
regarding the expected geographic sources of taxable income, gains from
investments, as well as tax planning strategies in assessing the need for a
valuation allowance. We determined that a valuation allowance of approximately
$3,700,000 relating to net operating loss carryovers was necessary to reduce our
deferred tax assets to the amount that will more likely than not be realized. As
a result, at December 31, 2008 the company has no net deferred tax assets. If
the estimates and assumptions used in our determination change in the future, we
could be required to revise our estimates of the valuation allowances against
our deferred tax assets and adjust our provisions for additional income taxes.
In the ordinary course of global business, there are transactions for which the
ultimate tax outcome is uncertain, thus judgment is required in determining the
worldwide provision for income taxes. We provide for income taxes on
transactions based on our estimate of the probable liability. We adjust our
provision as appropriate for changes that impact our underlying judgments.
Changes that impact provision

                                       11
<PAGE>
estimates include such items as jurisdictional interpretations on tax filing
positions based on the results of tax audits and general tax authority rulings.

PLAN OF OPERATIONS

     Over the course of the next 12 months, we intend to execute our business
plan and focus our business development efforts in the following key areas:

     o    By diversifying our product offerings to enhance the usefulness of our
          solutions for customers who will have already adopted one or more
          products;

     o    By enhancing our product lines and developing new products to attract
          new customers; and

     o    By developing partnering relationships with wide-ranging sales and
          distribution channel leaders already serving our vertical market space
          in a way that assists them in developing new revenue streams and
          opportunities through improved technical and sales support and
          customer services.

     Revenues are derived from sales and support services on our zNose product
line. Revenues for 2008 were approximately $473,000 or 22% below 2007. The
decrease in revenues was due to a significant drop in business from our Chinese
distributor in the first two quarters of the year. Even though business from
this customer recovered in the second half of the year, it was not enough to
offset the first half drop in business. Shipments picked up in the second half
of the year, its impact on revenues; however, was somewhat offset by aggressive
pricing on the Model 4200 which is being discontinued in its current
configuration at the end of the production run. The aggressive pricing also
prompted several customers to "buy down" from our higher priced model to the
Model 4200. As in the prior year, over 60% of our revenues were from
international customers who generate very little training and after-sales
support revenues. This is because most training and all after-sales support
needs for international customers are performed by the respective sales
representative or distributor servicing their respective accounts. Training and
after-sales support functions for domestic customers are performed by the
company.

     Cost of Sales consist of product costs and expenses associated with product
support services. Consistent with the decrease in revenues, cost of sales was
approximately $314,000 or 23% lower in 2008 than in 2007. As a percentage of
revenues, cost of sales were 60% and 62% for 2008 and 2007, respectively. Cost
of sales continue to be negatively impacted by manufacturing variances resulting
from a slow down in production to reflect lower sales activities and to work-off
existing inventory. Excluding the impact of the variances and other adjustments,
cost of sales would be 49% of revenues, 1% worse than in 2007.

     Research and development expenses primarily consist of salaries and related
benefits, material and supplies associated with our efforts in developing and
enhancing our products. In 2008, research and development expenses decreased
approximately $86,000 or 12% from 2007. The decrease is attributable to a
reduction of personnel expenses due to a reduction of census ($100,000),
reduction in patent attorney fees and consultants' expenses ($15,000), offset by
expenses associated with the development of the Model 4500.

     Selling expenses primarily consist of salaries, commissions and related
benefits associated with our selling and marketing efforts. Selling expenses
were approximately $193,000 lower in 2008 than in 2007. The decrease in selling
expenses resulted from savings through reduction of commission and consulting
expenses ($103,000), selective attendance at trade shows ($40,000), reduction in
personnel costs ($88,000), offset by an increase in promotional ($29,000) and
facility ($9,000) expenses.

                                       13
<PAGE>
     Compensation expenses primarily consist of salaries and related benefits of
our general and administrative personnel. The decrease in compensation expenses
of approximately $155,000 during 2008 when compared to 2007 is attributable to a
decrease in stock based compensation expense ($18,000), decrease in personnel
expenses through census reduction ($58,000), decrease in severance paid to
departed company officers ($53,000), and lower employee benefits expenses
($26,000).

     General and administrative expenses for 2008 were approximately 15% less
than 2007. The improvement of approximately $165,000 resulted from reductions of
legal and professional expenses ($32,000), deferred financing fees ($111,000),
Board of Directors meeting expenses ($92,000), travel and lodging ($17,000),
offset by increases in operating expenses ($6,000) and facilities cost
($81,000).

     Other income - derivative liabilities primarily consists of the decrease in
the fair value of derivative liabilities between the measurement dates which are
balance sheet dates. On March 31, 2008, we satisfied our obligations under the
8% convertible debentures and as a result, the company can assert that it has a
sufficient amount of authorized and unissued shares to settle its obligations
which can be settled in shares. Accordingly, the company reclassified all
contracts, warrants, and other convertible instruments outstanding at March 31,
2008 from liability to equity.

     Other income - gain from extinguishment of debt resulted from the early
retirement of the 8% convertible debentures on March 31, 2008 (see Item 8).

     Interest expense primarily consists of debt discount amortization and
interest on certain debt. The $2,037,000 reduction in interest expense is due to
retirement of the $7.0 million 8% convertible debentures, and related debt
discount, on March 31, 2008. Previously, interest expense included both interest
accrued on the 8% convertible debentures as well as amortization of the related
debt discount. Since the beginning of the second quarter, interest expense
pertains mostly to the interest accrued on the $2.0 million 9% convertible
debenture, which was issued on March 28, 2008.

LIQUIDITY AND CAPITAL RESOURCES

     Our cash and cash equivalents amounted to approximately $484,000 at
December 31, 2008.

     During 2008, we used approximately $1.755 million in our operating
activities which is the result of the following:

          o    A net loss of approximately $1.301 million adjusted for:

               o    depreciation and amortization of approximately $48,000,
                    increase in the reserve for obsolescence of approximately
                    $7,000, amortization of debt discount of approximately
                    $592,000, amortization of deferred financing costs of
                    approximately $45,000, issuance of shares for payment of
                    interest of $160,000, and stock based compensation of
                    approximately $96,000; and

               o    decreases in the fair value of the derivative liabilities of
                    approximately $323,000, allowance for doubtful accounts of
                    $1,500 and gain on extinguishment of debt of approximately
                    $1.262 million.

          o    Decreases in inventories of approximately $254,000, prepaid
               expenses of approximately $22,000, deferred revenues of
               approximately $42,000, accounts payable and accrued expenses of
               approximately $48,000 due to better management of cash
               expenditures, and increases in accounts receivable of
               approximately $2,000.

     During 2008, investing activities provided approximately $12,000 from
proceeds received from the sale of property and equipment, less property and
equipment purchased.

     During 2008, we generated approximately $1.979 million from financing
activities. The company received $5.5 million from an investor, $3.5 million for
the purchase of common stock of the company (at $0.0405 per share), and $2.0
million for a 9% convertible debenture. The 9% convertible debenture has a five
(5)-year term, and the conversion rate of the debenture is at $0.0486. A
condition of the new investment required the company to use $3.5 million to
extinguish the company's 8% convertible debentures. A Conversion and Termination
Agreement with the 8% convertible debenture holders on February 26, 2008,
provided that in exchange for $3.5 million, the debenture holders would convert
$3.5 million of the principal amount of their 8% convertible debentures,
together with interest thereon, at a conversion price of $0.35 per share of
Common Stock. Additionally, the agreement

                                       14
<PAGE>
provided that upon receipt of the foregoing sum and the conversion shares of
Common Stock, the debenture holders would cancel the remainder of their 8%
convertible debenture and 50% of the shares of Common Stock underlying warrants.
On March 31, 2008, upon payment of $3.5 million and remittance of the conversion
shares to the 8% convertible debenture holders, the entire $7.0 million 8%
convertible debentures was extinguished.

     Certificates of deposits, aggregating $15,500 at December 31, 2008, are
used to secure and collateralize the company's credit card liability and to
provide a performance guarantee for a sale to an oversea customer.

     During 2007, we used approximately $1.807 million in our operating
activities which is the result of the following:

          o    A net loss of approximately $4.375 million adjusted for:

               o    the amortization of debt discount of approximately $2.333
                    million, amortization of deferred financing costs of
                    approximately $182,000, issuance of shares for payment of
                    interest of $311,000, and stock based compensation of
                    $115,000, and a decrease in the fair value of the derivative
                    liabilities of approximately $980,000.

          o    A decrease in inventories of approximately $410,000 due to an
               extended slow down of production to work-off on-hand materials,
               and an increase in accounts payable and accrued expenses of
               approximately $117,000 due to better management of cash
               expenditures.

     During 2007, investing activities provided approximately $22,000 from
proceeds received from the sale of property and equipment.

     During 2007, we generated approximately $940,000 from financing activities
by liquidating a certificate of deposit that was used to satisfy collateral
requirement of our line of credit which we cancelled.

     There can be no assurance that any required or desired financing will be
available through any other bank borrowings, debt, or equity offerings, or
otherwise, on acceptable terms. If future financing requirements are satisfied
through the issuance of equity securities, investors may experience significant
dilution in the net book value per share of common stock. There is no guarantee
that a market will exist for the sale of our shares.

     Our primary capital needs are to fund our growth strategy, which includes
expanding our sales and marketing staff for the marketing, advertising and
selling of the zNose(R) family of chemical detection products, increasing
distribution channels both in the U.S. and foreign countries, introducing new
products, improving existing product lines and development of a strong corporate
infrastructure. We do not believe that we will have to incur significant capital
expenditures in the near future in order to meet our growth strategy goals.

     As of December 31, 2008, our cash balance and working capital were $484,000
and $1,028,000, respectively. The cash balance and working deficit as December
31, 2007 were $249,000 and $3,848,000.

SEASONALITY AND QUARTERLY RESULTS

     We have not experienced and do not foresee any seasonality to our revenues
or our results of operations.

INFLATION

     Although we currently use a limited number of sources for most of the
supplies and services that we use in the manufacturing of our vapor detection
and analysis technology, our raw materials and finished products are sourced
from cost-competitive industries. While prices for our raw materials may vary
significantly based on market trends, we have not experienced and do not foresee
any material inflationary trends for our product sources.

OFF BALANCE SHEET ARRANGEMENTS

     We do not have any off-balance sheet arrangements.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Electronic Sensor Technology, Inc.

     We have audited the accompanying balance sheets of Electronic Sensor
Technology, Inc. as of December 31, 2008 and 2007 and the related consolidated
statements of operations, changes in stockholders' deficit and cash flows for
the years ended December 31, 2008 and 2007. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

     We conducted our audit in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. The Company is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over financial
reporting. Accordingly we express no such opinion. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
the consolidated financial position of Electronic Sensor Technology, Inc., as of
December 31, 2008 and 2007 and the consolidated results of its operations and
its cash flows for the years ended December 31, 2008 and 2007 in conformity with
accounting principles generally accepted in the United States of America.

                          Notes to Financial Statements
                           December 31, 2008 and 2007

(1)  Nature of Business and Summary of Significant Accounting Policies

     Nature of Business

     Electronic Sensor Technology, Inc. develops and manufactures electronic
     devices used for vapor analysis. It markets its products through
     distribution channels in over 20 countries.

     Basis of Consolidation

     The accompanying financial statements include the accounts of the Company
     and its wholly owned subsidiaries. All intercompany balances and
     transactions have been eliminated in consolidation.

     Cash and Cash Equivalents

     The Company considers highly liquid financial instruments with maturities
     of three months or less at the time of purchase to be cash equivalents. The
     Company had cash and cash equivalents amounting to $484,028 and $248,587 at
     December 31, 2008 and 2007, respectively.

     Certificate of Deposit - Restricted

     The Company had two certificates of deposit in place at December 31, 2008.
     One, in the amount of $12,000, was used to secure and collateralize the
     Company's credit card liability. The other certificate of deposit in the
     amount of $3,500 was used to provide a performance guarantee for a sale to
     an oversea customer.

     Allowance for Doubtful Accounts

     The allowance for doubtful accounts is based on the Company's assessment of
     the collectability of customer accounts and the aging of the accounts
     receivable. If there is a deterioration of a major customer's credit
     worthiness or actual defaults are higher than the Company's historical
     experience, the Company's estimates of the recoverability of amounts due it
     could be adversely affected. The Company regularly reviews the adequacy of
     the Company's allowance for doubtful accounts through identification of
     specific receivables where it is expected that payments will not be
     received. The Company also establishes an unallocated reserve that is
     applied to all amounts that are not specifically identified. In determining
     specific receivables where collections may not be received, the Company
     reviews past due receivables and gives consideration to prior collection
     history and changes in the customer's overall business condition. The
     allowance for doubtful accounts reflects the Company's best estimate as of
     the reporting dates. Changes may occur in the future, which may require the
     Company to reassess the collectability of amounts and at which time the
     Company may need to provide additional allowances in excess of that
     currently provided.

     Fair Value of Financial Instruments

     The carrying value of cash and cash equivalents, certificate of deposit,
     accounts receivables, accounts payable and accrued expenses approximate
     their fair value due to their short-term maturities. The fair value of the
     9% convertible debentures issued by the Company on March 28, 2008 amounts
     to $2,000,000, based on the Company's incremental borrowing rate.

     Risk Factors

     Recently, the credit markets and the financial services industry have been
     experiencing a period of unprecedented turmoil and upheaval characterized
     by the bankruptcy, failure, collapse or sale of various financial
     institutions and an unprecedented level of intervention from the United
     States federal government. While the ultimate outcome of these events
     cannot be predicted, they may have a material adverse effect on the
     Company's liquidity and financial condition if its ability to borrow money
     to finance its operations from its existing lenders or from other sources,
     or obtain credit from trade creditors were to be impaired. In addition, the
     recent economic crisis could also adversely impact our customers' ability
     to finance the purchase of electronic

                                       F-6
<PAGE>
     instruments from us or our suppliers' ability to provide us with product,
     either of which may negatively impact the Company's business and results of
     operations.

     a.   Concentration of Credit

          The Company is subject to concentrations of credit risk primarily from
          cash and cash equivalents and accounts receivable. The Company's cash
          and cash equivalents accounts are held at financial institutions and
          are insured by the Federal Deposit Insurance Corporation ("FDIC") up
          to $100,000 at December 31, 2008. For the years ended December 31,
          2008 and 2007, the Company has reached bank balances exceeding the
          FDIC insurance limit. While the Company periodically evaluates the
          credit quality of the financial institutions in which it holds
          deposits, it cannot reasonably alleviate the risk associated with the
          sudden failure of such financial institutions. The Company's accounts
          receivables are due from distributors in all other countries in which
          it markets its products. The Company does not require collateral to
          secure its accounts receivables.

     b.   Product Concentration

          Substantially all of the Company's revenues were derived from the sale
          of electronic devices and related accessories used for vapor analysis.

     c.   Customer Concentration

          The Company's largest customer accounted for approximately 33% and 47%
          of its revenues during 2008 and 2007, respectively. This same customer
          and another customer accounted for approximately 96% and 86% of the
          gross accounts receivable balance at December 31, 2008 and 2007,
          respectively. No other customers accounted for more than 10% of its
          revenues or more than 10% of its net accounts receivable.

     d.   Geographic Concentration

          The Company sells its products internationally in 20 countries. Sales
          to these countries were approximately 63% and 66% for the years ended
          December 31, 2008 and 2007, respectively.

     Inventories

     Inventories are comprised of raw materials, work-in-process, and finished
     goods. Inventories are stated at the lower of cost or market, cost
     determined by the first-in, first-out (FIFO) method. The Company writes
     down its inventory for estimated obsolescence or unmarketable inventory
     using the difference between the cost of inventory and the estimated market
     value based upon assumptions about future demand and market conditions.

     Property and Equipment

     Property and equipment are recorded at cost and are depreciated on a
     straight-line basis over their estimated useful lives of five years.
     Leasehold improvements are recorded at cost and are amortized on a
     straight-line basis over the lesser of five years or the remaining
     lease-life. Maintenance and repairs are charged to expense as incurred.
     Significant renewals and betterments are capitalized.

     Property and equipment consist of the following as of December 31, 2008:

          Machinery and equipment            $  260,500
          Leasehold improvements                 39,500
          Office furniture and equipment        125,900
                                             ----------
                                                425,900
          Accumulated depreciation             (311,700)
                                             ----------
                                             $  114,200
                                             ==========

     Machinery and equipment includes a capital lease for $74,000. Depreciation
     expense amounted to approximately $48,300 and $56,500 during 2008 and 2007,
     respectively.

                                       F-7
<PAGE>
     Capital Lease

     On June 28, 2007, the Company entered into a capital lease under which the
     present value of the minimum lease payments amounted to $59,200. The lease
     expires in September 2010. The present value of the minimum lease payments
     was calculated using a discount rate of 11.41%. The principal balance of
     the capital lease obligation amounted to approximately $36,600 at December
     31, 2008, of which approximately $20,000 is included in the current portion
     of capital lease obligations in the accompanying consolidated balance
     sheet. As of December 31, 2008, the total future minimum lease payments on
     this lease is approximately $36,600 (if stated by year, the minimum lease
     payments are approximately: 2009 - $20,000, and 2010 - $16,600).

     Deferred Financing Costs

     Deferred financing costs consist of direct costs incurred by the Company in
     connection with the issuance of its 8% convertible debentures. The direct
     costs include cash payments and fair value of warrants issued to the
     placement agent, which secured the financing. Deferred financing costs are
     amortized over 48 months using the effective interest rate method. On March
     31, 2008, $3.5 million of the $7.0 million 8% convertible debentures was
     retired and the remaining $3.5 million was converted into equity. As such,
     the unamortized deferred financing costs related to the 8% convertible
     debentures were fully amortized as of March 31, 2008.

     Income Taxes

     Income taxes are accounted for in accordance with SFAS No. 109, Accounting
     for Income Taxes. SFAS No. 109 requires the recognition of deferred tax
     assets and liabilities to reflect the future tax consequences of events
     that have been recognized in the Company's financial statements or tax
     returns. Measurement of the deferred items is based on enacted tax laws. In
     the event the future consequences of differences between financial
     reporting bases and tax bases of the Company's assets and liabilities
     result in a deferred tax asset, SFAS No. 109 requires an evaluation of the
     probability of being able to realize the future benefits indicated by such
     assets. A valuation allowance related to a deferred tax asset is recorded
     when it is more likely than not that some or the entire deferred tax asset
     will not be realized.

     Use of Estimates

     The preparation of financial statements in accordance with accounting
     principles generally accepted in the United States requires management to
     make estimates and assumptions that affect the reported amounts of assets
     and liabilities and disclosure of contingent assets and liabilities at the
     date of the financial statements and the reported amounts of revenues and
     expenses during the reporting periods. Significant estimates made by
     management include, but are not limited to, the realization of receivables,
     recognition of stock based compensation and the valuation of the derivative
     liability. Actual results may differ from these estimates.

     Basic and Diluted Earnings per Share

     Basic earnings per share are calculated by dividing income available to
     stockholders by the weighted-average number of common shares outstanding
     during each period. Diluted earnings per share are computed by dividing
     income available to stockholders, adjusted for interest savings on the
     convertible debenture and changes in income or loss associated with the
     derivative contract that would result if the contract had been recorded as
     an equity instrument for accounting purposes during the period, by the
     weighted average number of common shares outstanding during the period plus
     the net effect of stock options and warrants, effect of the convertible
     debentures, and embedded conversion features.

     The outstanding options, warrants and shares equivalent issuable pursuant
     to embedded conversion features and warrants at December 31, 2008 are
     excluded from the loss per share computation for that period due to their
     antidilutive effect.

     The following sets forth the computation of basic and diluted earnings per
     share at December 31:

     Stock-Based Compensation

     The Company adopted SFAS No. 123R, "Share Based Payments." SFAS No. 123R
     requires companies to expense the value of employee stock options and
     similar awards and applies to all outstanding and vested stock-based
     awards.

     In computing the impact, the fair value of each option is estimated on the
     date of grant based on the Black-Scholes options-pricing model utilizing
     certain assumptions for a risk free interest rate; volatility; and expected
     remaining lives of the awards. The assumptions used in calculating the fair
     value of share-based payment awards represent management's best estimates,
     but these estimates involve inherent uncertainties and the application of
     management judgment. As a result, if factors change and the Company uses
     different assumptions, the Company's stock-based compensation expense could
     be materially different in the future. In addition, the Company is required
     to estimate the expected forfeiture rate and only recognize expense for
     those shares expected to vest. In estimating the Company's forfeiture rate,
     the Company analyzed its historical forfeiture rate, the remaining lives of
     unvested options, and the amount of vested options as a percentage of total
     options outstanding. If the Company's actual forfeiture rate is materially
     different from its estimate, or if the Company reevaluates the forfeiture
     rate in the future, the stock-based compensation expense could be
     significantly different from what we have recorded in the current period.
     The impact of applying SFAS No. 123R approximated $95,900 in additional
     compensation expense during the year ended December 31, 2008. Such amount
     is included in general and administrative expenses on the statement of
     operations.

     Accounts Payable and Accrued Expenses

     Accounts payable and accrued expenses at December 31, 2008 consist
     primarily of vendor payables.

     Deferred Revenues

     Deferred revenues consist of a one-time licensing fee received by the
     Company during 2004 and is recognized over the term of the agreement which
     is five years. The Company recognized revenues of $41,667 and $50,000
     pursuant to this agreement during 2008 and 2007, respectively.

     Derivative Liabilities

     The Company accounts for its liquidated damages pursuant to FASB Staff
     Position No. EITF 00-19-2 "Accounting for Registration Payment
     Arrangements" ("FSP 00-19-2"). FSP 00-19-2 provides that the contingent
     obligation to make future payments or otherwise transfer consideration
     under a registration payment arrangement, should be separately recognized
     and measured in accordance with FASB Statement No.5, "Accounting for
     Contingencies". The registration statement payment arrangement should be
     recognized and measured as a separate unit of account from the financial
     instrument(s) subject to that arrangement. If the transfer of consideration
     under a registration payment arrangement is probable and can be reasonably
     estimated at inception, such contingent liability is included in the
     allocation of proceeds from the related financing instrument. The Company
     had registered all shares underlying the 8% convertible debentures as well
     as all shares underlying the warrants related to the 8% convertible
     debentures, but no longer maintains such registration, in light of the
     partial conversion and partial cancellation of the debentures and a portion
     of the warrants (see Notes 3 and 4).

                                       F-9
<PAGE>
     The Company accounts for its embedded conversion features and freestanding
     warrants pursuant to SFAS No. 133, "Accounting for Derivative Instruments
     and Hedging Activities", which requires a periodic valuation of their fair
     value and a corresponding recognition of liabilities associated with such
     derivatives. The recognition of derivative liabilities related to the
     issuance of shares of common stock is applied first to the proceeds of such
     issuance, at the date of issuance, and the excess of derivative liabilities
     over the proceeds is recognized as other expense in the accompanying
     consolidated financial statements. The recognition of derivative
     liabilities related to the issuance of convertible debt is applied first to
     the proceeds of such issuance as a debt discount, at the date of issuance,
     and the excess of derivative liabilities over the proceeds is recognized as
     other expense in the accompanying consolidated financial statements. Any
     subsequent increase or decrease in the fair value of the derivative
     liabilities, which are measured at the balance sheet date, are recognized
     as other expense or other income, respectively.

     Research and Development

     Research and development costs are charged to operations as incurred and
     consists primarily of salaries and related benefits, raw materials and
     supplies.

     Segment reporting

     The Company operates in one segment, manufacturing of electronic devices
     used for vapor analysis. The Company's chief operating decision-maker
     evaluates the performance of the Company based upon revenues and expenses
     by functional areas as disclosed in the Company's statements of operations.

     Revenue Recognition

     The Company records revenue from direct sales of products to end-users when
     the products are shipped, collection of the purchase price is probable and
     the Company has no significant further obligations to the customer. Costs
     of remaining insignificant Company obligations, if any, are accrued as
     costs of revenue at the time of revenue recognition. Cash payments received
     in advance of product or service revenue are recorded as deferred revenue.

     Shipping and Handling

     The Company accounts for shipping and handling costs as a component of
     "Cost of Sales".

     Long-lived Assets

     The Company reviews long-lived assets, such as property and equipment, to
     be held and used or disposed of, for impairment whenever events or changes
     in circumstances indicate that the carrying amount of an asset may not be
     recoverable. If the sum of the expected cash flows, undiscounted and
     without interest, is less than the carrying amount of the asset, an
     impairment loss is recognized as the amount by which the carrying amount of
     the asset exceeds its fair value. At December 31, 2008 no assets were
     impaired.

     Recently Issued Accounting Pronouncements

     FASB Statement Number 160

     In December 2007, the FASB issued FASB Statement No. 160 - Noncontrolling
     Interests in Consolidated Financial Statements - an amendment of ARB No.
     51. This Statement applies to all entities that prepare consolidated
     financial statements, except not-for-profit organizations, but will affect
     only those entities that have an outstanding noncontrolling interest in one
     or more subsidiaries or that deconsolidate a subsidiary. Not-for-profit
     organizations should continue to apply the guidance in Accounting Research
     Bulletin No. 51, Consolidated Financial Statements, before the amendments
     made by this Statement, and any other applicable standards, until the Board
     issues interpretative guidance.

     This Statement amends ARB 51 to establish accounting and reporting
     standards for the noncontrolling interest in a subsidiary and for the
     deconsolidation of a subsidiary. It clarifies that a noncontrolling
     interest in a subsidiary is an ownership interest in the consolidated
     entity that should be reported as equity in the consolidated financial
     statements. Before this Statement was issued, limited guidance existed for
     reporting noncontrolling interests. As a result, considerable diversity in
     practice existed. So-called minority interests were reported in the
     consolidated statement of financial position as liabilities or in the
     mezzanine section between liabilities and equity. This Statement improves
     comparability by eliminating that diversity.

                                      F-10
<PAGE>
     A noncontrolling interest, sometimes called a minority interest, is the
     portion of equity in a subsidiary not attributable, directly or indirectly,
     to a parent. The objective of this Statement is to improve the relevance,
     comparability, and transparency of the financial information that a
     reporting entity provides in its consolidated financial statements by
     establishing accounting and reporting standards that require: (a) The
     ownership interests in subsidiaries held by parties other than the parent
     be clearly identified, labeled, and presented in the consolidated statement
     of financial position within equity, but separate from the parent's equity,
     (b) The amount of consolidated net income attributable to the parent and to
     the noncontrolling interest be clearly identified and presented on the face
     of the consolidated statement of income, (c) Changes in a parent's
     ownership interest while the parent retains its controlling financial
     interest in its subsidiary be accounted for consistently. A parent's
     ownership interest in a subsidiary changes if the parent purchases
     additional ownership interests in its subsidiary or if the parent sells
     some of its ownership interests in its subsidiary. It also changes if the
     subsidiary reacquires some of its ownership interests or the subsidiary
     issues additional ownership interests. All of those transactions are
     economically similar, and this Statement requires that they be accounted
     for similarly, as equity transactions, (d) When a subsidiary is
     deconsolidated, any retained noncontrolling equity investment in the former
     subsidiary be initially measured at fair value. The gain or loss on the
     deconsolidation of the subsidiary is measured using the fair value of any
     noncontrolling equity investment rather than the carrying amount of that
     retained investment, (e) Entities provide sufficient disclosures that
     clearly identify and distinguish between the interests of the parent and
     the interests of the noncontrolling owners.

     This Statement is effective for fiscal years, and interim periods within
     those fiscal years, beginning on or after December 15, 2008 (that is,
     January 1, 2009, for entities with calendar year-ends). Earlier adoption is
     prohibited. This Statement shall be applied prospectively as of the
     beginning of the fiscal year in which this Statement is initially applied,
     except for the presentation and disclosure requirements. The presentation
     and disclosure requirements shall be applied retrospectively for all
     periods presented. Management believes this Statement will have no impact
     on the financial statements of the Company once adopted.

     FASB 161 - Disclosures about Derivative Instruments and Hedging Activities

     In March 2008, the FASB issued FASB Statement No. 161, which amends and
     expands the disclosure requirements of FASB Statement No. 133 with the
     intent to provide users of financial statements with an enhanced
     understanding of; how and why an entity uses derivative instruments, how
     the derivative instruments and the related hedged items are accounted for
     and how the related hedged items affect an entity's financial position,
     performance and cash flows. This Statement is effective for financial
     statements for fiscal years and interim periods beginning after November
     15, 2008. Management believes this Statement will have no impact on the
     financial statements of the Company once adopted.

     FASB 161 - The Hierarchy of Generally Accepted Accounting Principles

     In May 2008, the Financial Accounting Standards Board (FASB) issued
     Statement of Financial Accounting Standards (SFAS) No. 162, "The Hierarchy
     of Generally Accepted Accounting Principles." The new standard is intended
     to improve financial reporting by identifying a consistent framework, or
     hierarchy, for selecting accounting principles to be used in preparing
     financial statements that are presented in conformity with U.S. generally
     accepted accounting principles (GAAP) for non-governmental entities. We are
     currently evaluating the effects, if any, that SFAS No. 162 may have on our
     financial reporting.

(2)  Inventory

     Inventory consists of the following:

                                       December 31, 2008      December 31, 2007
                                       -----------------      -----------------
               Finished goods                 $  341,530             $  475,091
               Work-in-process                     4,816                360,671
               Raw materials                     311,108                 76,030
               Reserve for obsolescence         (100,000)              (92,803)
                                              ----------             ----------
                                              $  557,454             $  818,989
                                              ==========             ==========

     Inventories are stated at the lower of cost or market, cost determined by
     the first-in, first-out (FIFO) method. The Company writes down its
     inventory for estimated obsolescence or unmarketable inventory equal to the
     difference between the cost of inventory and the estimated market value
     based upon assumptions about future demand and market conditions. The
     Company writes down inventory during the period in which such products are
     no longer marketable in any of their markets due to governmental
     regulations as well as inventory which matures within the next three months
     of the measurement date.

(3)  Convertible debentures

     8% Convertible Debentures

     During December 2005, we issued in a private offering, $7,000,000 aggregate
     principal amount of 8% convertible debentures due December 7, 2009. The
     convertible debentures were convertible at any time on or prior to the
     maturity date at the option of the debenture holder at a conversion price
     of $0.4544, which was subsequently reduced to $0.4000 as per a Forbearance
     and Amendment Agreement, dated September 7, 2006, with the holders of the
     convertible debentures and can be redeemed at the lesser of $0.4000 or 90%
     of the average of the volume weighted average price for the 20 consecutive
     trading days immediately prior to the conversion date. Interest on the
     convertible debentures was payable in cash or stock, at the Company's
     option.

     In connection with the issuance of the convertible debentures, the Company
     issued five-year warrants to purchase 12,130,314 shares of common stock at
     an exercise price of $0.4761 per share, which was subsequently reduced to
     $0.4300 per share as per a Forbearance and Amendment Agreement, dated
     September 7, 2006, with the holders of the warrants.

     We paid professional fees of approximately $592,000 and issued 485,213
     warrants with a fair value of approximately $136,000 relating to the
     issuance of the convertible debentures and warrants. The payments of
     professional fees and the fair value of the warrants, aggregating
     approximately $729,000, were recorded as deferred financing costs.

     A Conversion and Termination Agreement was entered into with the debenture
     holders on February 26, 2008. Pursuant to the agreement, the convertible
     debenture holders agreed that in exchange for $3,500,000, the debenture
     holders would convert $3,500,000 of the principal amount of their 8%
     convertible debentures, together with accrued interest thereon, at a
     conversion price of $0.35 per share of Common Stock. Upon receipt of the
     foregoing sum and the conversion shares of Common Stock, the debenture
     holders agreed to cancel the remainder of their 8% convertible debentures
     and 50% of the shares of Common Stock underlying warrants. With respect to
     the remaining 6,065,157 shares of Common Stock underlying the warrants,
     they will otherwise continue in full force and effect in accordance with
     their terms. On March 31, 2008, we remitted $3,500,000 in cash and
     transferred 10,400,000 shares of common stock to the debenture holders to
     completely retire the 8% convertible debentures.

     The extinguishment of the convertible debentures resulted in a gain of
     approximately $1,261,900, which included the write off of related
     unamortized deferred financing costs of approximately $302,600.

     9% Convertible Debentures

     On March 28, 2008, we received $5,500,000 from an investor, $3,500,000 of
     which was for Common Stock of the Company, and $2,000,000 for a convertible
     debenture bearing an interest rate of 9%, payable semi-annually in cash.
     The common stock shares were issued at a price of $0.0405 per share. The 9%
     convertible debenture has a five (5)-year term, and the conversion rate of
     the debenture is $0.0486 (equaled to 41,152,263 common shares). The
     difference between the conversion rate of the debenture and the closing
     price of the Company's common stock on the date of issuance resulted in a
     note discount of approximately $58,000. The note discount will be amortized
     over the term of the convertible debenture. The unamortized balance at
     December 31, 2008 was approximately $49,000.

     A condition of the new investment required the Company to use $3,500,000 to
     extinguish the 8% convertible debentures and this event occurred on March
     31, 2008.

(4)  Derivative Liabilities

     In connection with the issuance of the 8% convertible debentures in
     December 2005, the Company determined that the conversion feature of the
     convertible debentures represents an embedded derivative since the
     debentures are convertible into a variable number of shares upon
     conversion. Because there is no explicit number of shares that are to be
     delivered upon satisfaction of the convertible debentures and that there is
     no cap on the number of shares to be delivered upon expiration of the
     contract to a fixed number, the Company is unable to assert that it had
     sufficient authorized and unissued shares to settle its obligations under
     the convertible debentures and therefore, net-share settlement is not
     within the control of the Company. Accordingly, the convertible debentures
     are not considered to be conventional debt under EITF 00-19 and the
     embedded conversion feature must be bifurcated from the debt host and
     accounted for as a derivative liability.

                                      F-12
<PAGE>
     A Conversion and Termination Agreement was entered into with the 8%
     convertible debenture holders on February 26, 2008. Pursuant to the
     agreement, the convertible debenture holders agreed that in exchange for
     $3,500,000, the debenture holders would convert $3,500,000 of the principal
     amount of their 8% convertible debentures, together with accrued interest
     thereon, at a conversion price of $0.35 per share of Common Stock. Upon
     receipt of the foregoing sum and the conversion shares of Common Stock, the
     debenture holders agreed to cancel the remainder of their 8% convertible
     debentures and 50% of the shares of Common Stock underlying warrants. With
     respect to the remaining shares of Common Stock underlying the warrants,
     they will otherwise continue in full force and effect in accordance with
     their terms. On March 31, 2008, we remitted $3,500,000 in cash and
     transferred 10,400,000 shares of Common Stock to the debenture holders.

     As a result of the satisfaction of the Company's obligations under its 8%
     convertible debentures, the Company reclassified the derivative liabilities
     balance outstanding at March 31, 2008 from liability to equity. The amount
     of derivative liabilities that was reclassified to equity approximated
     $2,053,000.

(5)  Stockholders' Deficit

     Common Stock

     Shares issued for payment of interest

     During 2008, the Company elected interest accrued on the 8% convertible
     debentures in shares of the Company's common stock, rather than in cash.
     The Company issued 2,677,534 shares of the Company's common stock to the
     holders of the 8% convertible debentures.

     Shares issued to private investor

     On March 28, 2008, we received $5,500,000 from an investor, $3,500,000 of
     which was for Common Stock of the Company, and $2,000,000 for a convertible
     debenture bearing an interest rate of 9%, payable semi-annually in cash
     (see Note 3). The common stock shares were issued at a price of $0.0405 per
     share. The number of common shares issued to this investor was 86,419,753.

     Shares issued for conversion of 8% convertible debentures

     A Conversion and Termination Agreement was entered into with the debenture
     holders on February 26, 2008. Pursuant to the agreement, the convertible
     debenture holders agreed that in exchange for $3,500,000, the debenture
     holders would convert $3,500,000 of the principal amount of their 8%
     convertible debentures, together with accrued interest thereon, at a
     conversion price of $0.35 per share of Common Stock (see Note 3). On March
     31, 2008, we remitted $3,500,000 in cash and transferred 10,400,000 (of
     which 400,000 common shares pertained to accrued interest) shares of common
     stock to the debenture holders to retire $3,500,000 of the 8% convertible
     debentures.

     Options

     In 2005, the Board of Directors adopted the Electronic Sensor Technology,
     Inc. 2005 Stock Incentive Plan. The purpose of the Stock Incentive Plan is
     to attract and retain the services of experienced and knowledgeable
     individuals to serve as our employees, consultants and directors. On the
     date the Stock Incentive Plan was adopted, the total number of shares of
     common stock subject to it was 5,000,000. The Stock Incentive Plan is
     currently administered by the Board of Directors, and may be administered
     by any Committee authorized by the Board of Directors, so long as any such
     Committee is made up of Non-Employee Directors, as that term is defined in
     Rule 16(b)-3(b) of the Securities Exchange Act of 1934.

     The Stock Incentive Plan is divided into two separate equity programs: the
     Discretionary Option Grant Program and the Stock Issuance Program. Under
     the Discretionary Option Grant Program, eligible persons may, at the
     discretion of the administrator, be granted options to purchase shares of
     common stock and stock appreciation rights. Under the Stock Issuance
     Program, eligible persons may, at the discretion of the administrator, be
     issued shares of common stock directly, either through the immediate
     purchase of such shares or as a bonus for services rendered for Electronic
     Sensor Technology (or a parent or subsidiary of Electronic Sensor
     Technology).

     Pursuant to the terms of the Discretionary Option Grant Program, the
     exercise price per share is fixed by the administrator, but may not be less
     than 85% of the fair market value of the common stock on the date of grant,
     unless the recipient of a grant

                                      F-13
<PAGE>
     owns 10% or more of Electronic Sensor Technology's common stock, in which
     case the exercise price of the option must not be less than 110% of the
     fair market value. An option grant may be subject to vesting conditions.
     Options may be exercised in cash, with shares of the common stock of
     Electronic Sensor Technology already owned by the person or through a
     special sale and remittance procedure, provided that all applicable laws
     relating to the regulation and sale of securities have been complied with.
     This special sale and remittance procedure involves the optionee
     concurrently providing irrevocable written instructions to: (i) a
     designated brokerage firm to effect the immediate sale of the purchased
     shares and remit to Electronic Sensor Technology, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     federal, state and local income and employment taxes required to be
     withheld by Electronic Sensor Technology by reason of such exercise and
     (ii) Electronic Sensor Technology to deliver the certificates for the
     purchased shares directly to such brokerage firm in order to complete the
     sale. The term of an option granted pursuant to the Discretionary Option
     Grant Program may not be more than 10 years.

     The Discretionary Option Grant Program also allows for the granting of
     Incentive Options to purchase common stock, which may only be granted to
     employees, and are subject to certain dollar limitations. Any options
     granted under the Discretionary Option Grant Program that are not Incentive
     Options are considered Non-Statutory Options and are governed by the
     aforementioned terms. The exercise price of an Incentive Option must be no
     less than 100% of the fair market value of the common stock on the date of
     grant, unless the recipient of an award owns 10% or more of Electronic
     Sensor Technology's common stock, in which case the exercise price of an
     incentive stock option must not be less than 110% of the fair market value.
     The term of an Incentive Option granted may not be more than five years if
     the option is granted to a recipient who owns 10% or more of Electronic
     Sensor Technology's common stock, or 10 years for all other recipients of
     Incentive Options. Incentive Options are otherwise governed by the general
     terms of the Discretionary Option Grant Program.

     Pursuant to the terms of the Stock Issuance Program, the purchase price per
     share of common stock issued is fixed by the administrator, but may not be
     less than 85% of the fair market value of the common stock on the issuance
     date, unless the recipient of a such common stock owns 10% or more of
     Electronic Sensor Technology's common stock, in which case the purchase
     price must not be less than 100% of the fair market value. Common stock may
     be issued in exchange for cash or past services rendered to Electronic
     Sensor Technology (or any parent or subsidiary of Electronic Sensor
     Technology). Common stock issued may be fully and immediately vested upon
     issuance or may vest in one or more installments, at the discretion of the
     administrator.

     Management used Black Scholes methodology to determine the fair value of
     the options on the date of issue based on the following assumptions. The
     expected volatility was based on the average historical volatility of
     comparable publicly-traded companies.

              Expected life of option            5 years             5 years

     The fair value of the granted stock options shares was approximately
     $258,000 or $0.06 per share. Approximately $96,000 was charged to
     compensation expense in 2008. The remaining amount will be amortized to
     compensation expense over future periods based on the vesting schedule of
     the respective stock option shares. The total compensation cost related to
     nonvested awards not yet recognized amounted to approximately $36,000 and
     $112,000 at December 31, 2008 and 2007, respectively. This compensation
     cost will be recognized over the weighted average period of the remaining
     terms of the stock options, unless the options are terminated sooner.

     Eligible employees may also elect to contribute a percentage of their
     compensation to the Plan. During 2008 and 2007, the Company contributed
     approximately $33,300 and $32,300, respectively, to the Plan.

(8)  Income Taxes

     Deferred income taxes reflect the net tax effect of temporary differences
     between the carrying amounts of assets and liabilities for financial
     reporting purposes and the amounts used for income tax purposes.
     Significant components of the net deferred taxes are as follows:

                                                      2008            2007
                                                      ----            ----

             Less valuation allowance              (3,700,000)      (3,300,000)
                                                 ------------     ------------

                                                 ============     ============

     The Company's net operating losses totaled approximately $9.1 million at
     December 31, 2008, and will expire in 2028.

     SFAS No. 109 requires a valuation allowance to reduce the deferred tax
     assets reported, if any, based on the weight of the evidence, it is more
     likely than not that some portion or all of the deferred tax assets will
     not be realized. Management has determined that a valuation allowance of
     $3,700,000 at December 31, 2008 is necessary to reduce the deferred tax
     assets to the amount that will more likely than not be realized. The change
     in the valuation allowance during 2008 and 2007 was an increase of
     approximately $400,000 and $1,300,000 respectively.

     The federal statutory tax rate reconciled to the effective tax rate during
     2008 and 2007, respectively, is as follows:

                                                   2008         2007

(9)  Subsequent Events

     On April 10, 2009, the Company received $1 million from an investor in
     exchange for a debenture bearing an interest rate of 9% with a maturity of
     one year. The debenture grants the investor a security interest in all of
     the intellectual property of the Company.

Item 9A(T). Controls and Procedures.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

     The company's Chief Executive Officer and Chief Financial Officer, after
evaluating the effectiveness of the company's disclosure controls and procedures
(as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as
amended) as of the end of the period covered by this annual report on Form 10-K,
have concluded that, based on such evaluation, the company's disclosure controls
and procedures were effective to ensure that material information relating to
the company is recorded, processed, summarized, and reported in a timely matter.
In designing and evaluating the disclosure controls and procedures, the
company's management recognized that any controls and procedures, no matter how
well designed and operated, can provide only reasonable assurance of achieving
the desired control objectives, and the company's management necessarily was
required to apply its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

     The management of the company is responsible for establishing and
maintaining adequate internal control over financial reporting. Internal control
over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f)
promulgated under the Securities Exchange Act of 1934, as amended, as a process
designed by, or under the supervision of, the company's principal executive and
principal financial officers and effected by the company's Board of Directors,
management and other personnel, to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted accounting
principles. The company's internal control over financial reporting includes
those policies and procedures that:

     o    pertain to the maintenance of records that, in reasonable detail,
          accurately and fairly reflect the transactions and dispositions of the
          assets of the company;

     o    provide reasonable assurance that transactions are recorded as
          necessary to permit preparation of financial statements in accordance
          with generally accepted accounting principles, and that receipts and
          expenditures of the company are being made only in accordance with
          authorizations of management and directors of the company; and

     o    provide reasonable assurance regarding prevention or timely detection
          of unauthorized acquisition, use or disposition of the company's
          assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

The company's management assessed the effectiveness of the company's internal
control over financial reporting as of December 31, 2008. In making this
assessment, it used the criteria set forth in the Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO). Based on its assessment, the company's management has
concluded that, as of December 31, 2008, the company's internal control over
financial reporting is effective based on those criteria. This report does not
include an attestation report of our registered public accounting firm regarding
internal control over financial reporting. Management's report was not subject
to attestation by our registered public accounting firm pursuant to temporary
rules of the Securities and Exchange Commission that permit us to provide only
management's report in this annual report.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

     During the quarter ended December 31, 2008, there were no changes in our
internal control over financial reporting that materially affected, or are
reasonably likely to materially affect, our internal control over financial
reporting.

Midsummer Investment, Ltd. and Islandia, L.P.

     On September 7, 2006, Electronic Sensor Technology entered into a
Forbearance and Amendment Agreement with Midsummer Investment, Ltd. and
Islandia, L.P., which, at such time, each held an 8% convertible debenture and a

share of common stock, and the remaining shares of common stock underlying the
warrants held by Midsummer and Islandia were reduced by 50%.

DIRECTOR INDEPENDENCE

     Although we are not required to have independent directors on our Board of
Directors because our securities are not listed on a national securities
exchange or an inter-dealer quotation system that has director independence
requirements, two of the five directors on our Board are independent using the
definition of "independent director" contained in Rule 5605(a)(2) of the NASDAQ
Marketplace Rules. Our independent directors are Low Gay Teck and Thomas Dudley.
Under Rule 5605(a)(2) of the NASDAQ Marketplace Rules, an "independent director"
is generally defined as a person other than an executive officer or employee of
the company or another individual having a relationship which, in the opinion of
the company's Board of Directors, would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director.

     The members of our audit committee and our compensation committee include
Thomas Dudley, who is also the chairman of both committees, Maggie Tham and
William Wittmeyer. In addition to being an independent director under Rule
5605(a)(2), the NASDAQ audit committee independence standards (which are also
not applicable to us) contain NASDAQ Marketplace Rule 5605(c), which requires
that audit committee members meet certain additional independence requirements.
Thomas Dudley is independent under the NASDAQ audit committee independence
standards.
