                       ELECTRONIC SENSOR TECHNOLOGY, INC.
                          Notes to Financial Statements
                                   (Unaudited)
                                 March 31, 2005

(1)   Basis of Presentation

      The accompanying unaudited consolidated financial statements have been
      prepared in accordance with generally accepted accounting principles for
      interim financial statements and with the instructions to Form 10-QSB and
      Article 10 of Regulation S-X. Accordingly, they do not include all the
      information and disclosures required for annual financial statements.
      These financial statements should be read in conjunction with the
      consolidated financial statements and related footnotes for the year ended
      December 31, 2004, included in the Form 8-K filed with the SEC on April
      19, 2005.

      In the opinion of the Company's management, all adjustments (consisting of
      normal recurring accruals) necessary to present fairly the Company's
      financial position as of March 31, 2005, and the results of operations and
      cash flows for the three month period ending March 31, 2004 have been
      included. The results of operations for the three month period ended March
      31, 2005 are not necessarily indicative of the results to be expected for
      the full year. For further information, refer to the consolidated
      financial statements and footnotes thereto included in the Company's Form
      8-K as filed with the Securities and Exchange Commission for the year
      ended December 31, 2004.

(2)   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.

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

      (a)   Nature of Business

            Electronic Sensor Technology, Inc. (the "Company") (formerly
            Bluestone Ventures, Inc.) develops and manufactures electronic
            devices used for vapor analysis.

      (b)   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 did not have any cash equivalents at
            March 31, 2005.

      (c)   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.


                                       6


      (d)   Shipping and Handling

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

      (e)   Property and Equipment

            Property and equipment are stated at cost, net of accumulated
            depreciation. Depreciation is computed using the straight-line
            method over the estimated useful lives of five years.

      (f)   Inventories

            Inventories are comprised of raw materials, work in process, and
            finished goods. Inventories are stated at the lower of cost or
            market and are determined using the first-in, first-out method.

      (g)   Use of Estimates

            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.

      (h)   Fair Value of Financial Instruments

            The fair value of certain financial instruments, including accounts
            receivable, accounts payable and accrued liabilities, approximates
            their carrying value due to the short maturity of these instruments.

      (i)   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 March 31, 2005 no assets were impaired.

(3)   Mergers and Acquisitions

Bluestone Ventures, Inc. ("Bluestone") executed an Agreement and Plan of Merger
("Merger Agreement") by and among Bluestone, Amerasia Technology, Inc.,
("Amerasia"), holder of approximately 55% of the partnership interests of
Electronic Sensor Technology, L.P., ("EST"), L & G Sensor Technology, L.P.,
("L&G"), holder of approximately 45% of the partnership interests of EST,
Amerasia Acquisition Corp., ("AAC") a wholly-owned subsidiary of Bluestone, and
L & G Acquisition Corp., ("LAC") a wholly owned subsidiary of Bluestone on
January 31, 2005. Under the Merger Agreement (i) AAC merged with and into
Amerasia such that Amerasia became a wholly-owned subsidiary of Bluestone, (ii)
LAC merged with and into L&G such that L&G became a wholly-owned subsidiary of
Bluestone, (iii) as a result of the merger of (i) and (ii), Bluestone indirectly
acquired all of the partnership interests of EST and (iv) Bluestone issued
20,000,000 shares of its common stock to the shareholders of Amerasia and L&G.
This merger has been treated as a purchase only of the partnership interests of
Electronic Sensor Technology L.P.


                                       7


For accounting purposes, the transaction will be treated as a recapitalization
of EST and accounted for as a reverse acquisition.

Bluestone also entered into various Subscription Agreements with certain
investors on January 31, 2005. Under these Subscription Agreements, Bluestone
issued 3,985,000 shares of its common stock ("shares") and warrants to purchase
3,985,000 shares at $1.00 per share to certain investors for gross proceeds of
$3,985,000. Bluestone received the gross proceeds of the sale of these shares on
February 1, 2005. Bluestone received net proceeds of approximately $3,822,000.
This amount was net of legal fees, including counsel fees for the investors and
EST of approximately $163,000.

By virtue of the Mergers, all shares of common stock of Amerasia were converted
into the right to receive shares of common stock of Bluestone at an exchange
ratio of 4.6223537 shares of Bluestone common stock for each share of Amerasia
common stock and all shares of common stock L&G were converted into the right to
receive shares of common stock of Bluestone at an exchange ratio of 90 shares of
Bluestone common stock for each share of L&G common stock. In addition, all
200,000 Class C limited partnership units of Electronic Sensor Technology L.P.
were automatically converted into 200,000 shares of Bluestone common stock.

The purchase price for the Mergers was 20,000,000 shares of Bluestone common
stock. The closing of the mergers occurred on February 1, 2005 (the "Closing
Date").

In January 2005 the loans payable to three partners of Electronic Sensor
Technology L.P., totaling $1,198,630 were converted into 1,198,630 shares of
common stock of Bluestone.

In January 2005 the notes payable to related parties of $1,272,000 plus accrued
interest were converted into 1,585,111 shares of common stock of Bluestone.
Bluestone has changed its name to Electronic Sensor Technology, Inc. as of
February 2005.

(b)   Stock Option Plan

The Company adopted a Stock Incentive Option Plan in April 2005. There were
969,500 initial options granted to former EST limited partnership employees.

Overview

      We are engaged in the development, manufacturing, and sales 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) is capable of measuring and quantifying the chemistry
of any compound, fragrance, vapor or odor with parts per trillion sensitivity in
10 seconds. We also believe the zNose(R) has the unique ability to quantify and
speciate the subject chemical vapor by creating visual olfactory images. This
enables the measured odor or vapor to be easily identified by the user.

      We believe that our products will have broad applications in the homeland
security and laboratory instrumentation 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
assembling our sales and support organization.

      Electronic Sensor Technology, Inc. ("EST") was originally incorporated
under the name "Bluestone Ventures, Inc.", on July 12, 2000. From inception
until February 1, 2005, we engaged in the business of acquiring, exploring and
developing certain mining properties in Canada. Upon the acquisition of
Electronic Sensor Technology, LP (the "ELP"), we abandoned our mining business
and adopted ELP's business of developing, manufacturing and selling the vapor
analysis device. Prior to the closing of the Mergers, on January 26, 2005, we
changed our name to "Electronic Sensor Technology, Inc."

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

Quarter Ended March 31, 2005 Compared to Quarter Ended March 31, 2004

      Revenues for the quarter ended March 31, 2005 were $207,000 compared to
$305,000 in 2004. Our revenues experienced a decline of 32% due to the slip of
deliveries of some newly re-designed parts.

      Gross profit was ($83,000) for the first quarter ended March 31, 2005
compared to $61,000 for the quarter ended March 31, 2004. This decrease of
$144,000 resulted from increased manufacturing costs from additional personnel.

      Compensation expenses in the first quarter of 2005 were $59,000 as
compared to $67,000 in 2004. As a percentage of sales, total compensation
expenses increased from 22% of sales to 29% of sales. The decrease of $8,000 was
due to a decrease of sales commissions.

      Selling expenses in the first quarter of 2005 were $39,000 as compared to
$8,000 in 2004. As a percentage of sales, total selling expenses increased from
3% of sales to 19% of sales. This increase of $31,000 was due to an increase of
personnel costs.

      General and administrative expenses for the first quarter of 2005 were
$470,000 as compared to $83,000 in 2004. As a percentage of sales, general and
administration expenses increased from 27% of sales to 227% of sales. This
increase of $386,000 was primarily due to consulting and professional fees in
connection with the reverse merger.

      Interest expense for the first quarter of 2005 was $20,566 as compared to
$16,370 for the same period in 2004. This increase in interest expense is due
to expanded line of credit and higher interest rate.

      Net Loss was $659,000 for the period ended March 31, 2005 as compared to a
loss of $146,000 for the three- month period ended March 31, 2004. The increase
was primarily due to higher operating expenses in first quarter of 2005
including one time charges in connection with the reverse merger.

Liquidity and Capital Resources

      In the first quarter of 2005 net cash used by the Company for operating
activities was $709,000. In the first quarter of 2004, the cash provided by
Company's operations was $287,000. Cash used in the first quarter of 2005 was
comprised of the net loss incurred for the quarter of $659,000, plus net
non-cash expenses of $2,000 plus the net change in operating assets and
liabilities of $(52,000). Cash used in operations in the first quarter of 2004
was comprised of the net loss of $146,000 plus net non-cash expenses of $7,000,
plus the net change in operating assets and liabilities of cash of $426,000.

      Investing activities used cash of $39,000 in the first quarter of 2005 and
provided $9,700 during the first quarter ended March 31, 2004. In 2005 and 2004
the cash was used to purchase of equipment.

      Financing activities provided cash of $3.5 million and used cash of
$373,000 during the first quarters ended March 31, 2005 and 2004, respectively.

      At March 31, 2005 the Company had cash of $2.8 million compared to $45,000
at March 31, 2004. At March 31, 2005, the Company had working capital of $1.25
million, as compared to working deficit of $5.5 million at March 31, 2004. The
Company, at present, has a credit facility in place with East West Bank for $1.8
million.

      Although we have a bank operating line of credit, there can be no
assurance that these proceeds will be adequate for our capital needs. 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 and there is no guarantee that a
market will exist for the sale of the Company's shares.


                                       10


      The Company's primary capital needs are to fund its growth strategy, which
includes creating a sales and marketing staff for the marketing, advertising and
selling of zNose(R) family of chemical detection products, increasing
distribution channels, introducing new products, improving existing product
lines and development of a strong corporate infrastructure.

Seasonality and Quarterly Results

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

Inflation

      Our raw materials and finished products are sourced from cost-competitive
industries. As such, we do not foresee any material inflationary trends for our
product sources.

      Our business is subject to a number of risks as outlined below. An
investment in our securities is speculative in nature and involves a high degree
of risk. You should read this annual report carefully and consider the following
risk factors:

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

RISKS RELATED TO OUR COMPANY

We have a significant accumulated deficit and have received an opinion from our
auditors regarding our ability to continue as a going concern, and we may never
achieve profitability.

      We have incurred significant net losses every year since our inception,
including net losses in 2004 and 2003. These losses have resulted principally
from expenses incurred in our research and development programs and general and
administrative expenses. To date, we have not yet generated significant
recurring revenues. Our limited revenues that derive from sales of the zNose(R)
product have not been and may not be sufficient to sustain our operations. We
anticipate that we will continue to incur substantial operating losses based on
projected sales revenues less manufacturing, general and administrative and
other operating costs for an indefinite period of time. We expect that our
revenues will not be sufficient to sustain our operations for the foreseeable
future, notwithstanding any anticipated revenues we may receive when our vapor
detection products obtain increased visibility in our markets, due to the
significant costs associated with the development and marketing of our products.
No assurances can be given when we will ever be profitable.

      Our independent auditors have added an explanatory paragraph to their
audit opinions issued in connection with the financial statements for each of
the years ended December 31, 2004 and 2003 relative to the substantial doubt
about our ability to continue as a going concern. Our ability to obtain
additional funding will determine our ability to continue as a going concern.
Our financial statements do not include any adjustments that might result from
the outcome of this uncertainty.

      We expect to continue to experience losses until the time, if ever, when
we are able to sell products sufficient to generate revenues adequate to support
our operations. If we fail to become profitable, we may be forced to cease
operations.

Our limited manufacturing experience and capacity may limit our ability to grow
our revenues.

      To be successful, we must manufacture our products in compliance with
industry standards and on a timely basis, while maintaining product quality and
acceptable manufacturing costs. We also 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. We do not have agreements with
our suppliers. Our manufacturing strategy presents the following risks:

      o     delays in the quantities needed for product development could delay
            commercialization of or products in development;

      o     if market demand for our products increases suddenly, our current
            suppliers might not be able to fulfill our commercial needs, which
            would require us to seek new supply arrangements and may result in
            substantial delays in meeting market demand; and

      o     we may not have intellectual property rights, or may have to share
            intellectual property rights, to any improvements in the
            manufacturing processes or new manufacturing processes for our
            products.


                                       11


      Any of these factors could delay commercialization of our products under
development, entail higher costs and result in our being unable to effectively
sell our products.

We face significant competition and our business and financial results could
suffer from competition.

      While we are unaware of any competitor that has created a vapor analysis
device similar to the zNose(R), there are companies that offer products and
services that compete with the zNose(R) in our markets. See "Business -
Competition." We believe that manufacturers of X-Rays, Ion Mobility
Spectroscopy, and other electronic noses compete with us in the security-related
markets. In the analytic instrumentation markets, we compete with many gas
chromatograph manufacturers including Perkin-Elmer (PKI:NYSE) and Agilent
Technologies (A:NYSE). Many of our existing and potential competitors have
longer operating histories, greater experience, greater name recognition, larger
customer bases and significantly greater financial, technical and marketing
resources than we do. Because of their greater resources, our competitors are
able to undertake more extensive marketing campaigns for their products and
services, and make more attractive offers to potential employees, strategic
partners, and others. We may not be able to compete successfully against our
current or future competitors and our business and financial results could
suffer from such competition.

If our products do not achieve a significant level of market acceptance, it is
highly unlikely that we ever will become profitable.

      To our knowledge, electronic nose technology, and our zNose(R) product,
has yet to receive widespread market acceptance in the markets we are focused
on. The commercial success of our current and future products will depend upon
the adoption of our zNose(R) technology by our customers. In order to be
successful, our future products must meet the technical and cost requirements
for the markets we intend to penetrate. Market acceptance will depend on many
factors, including:

      o     our ability to convince potential customers to adopt our products;

      o     the willingness and ability of potential customers to adopt our
            products;

      o     our ability to sell and service sufficient quantities of our
            products; and

      o     new, advanced technology offered by other companies which compete
            with our products.

      Because of these and other factors, our products may not achieve market
acceptance. If our products do not achieve a significant level of market
acceptance, demand for our future products will not develop as expected and it
is highly unlikely that we ever will become profitable.

Other companies could create a technology which competes effectively with our
zNose(R) technology, and we may be unable to maintain our existing, or capture
additional, market share in our markets.

      Based upon our review of the industry, we are unaware of any company today
that markets a technology which is similar to our zNose(R) technology.
Nonetheless, our intended markets generally are dominated by a very large
corporations (or their subsidiaries), which have greater access to capital,
manpower, technical expertise, distribution channels and other elements which
would give them a huge competitive advantage over us were they to begin to
compete directly against us. It is possible that these and other competitors may
implement new, advanced technologies before we are able to, allowing them to
provide more effective products at more competitive prices. Any number of future
technological developments could:

      o     adversely impact our competitive position;

      o     require write-downs of obsolete technology;

      o     require us to discontinue production of obsolete products before we
            can recover any or all of our related research, development and
            commercialization expenses; or

      o     require significant capital expenditures beyond those currently
            contemplated.


                                       12


      We cannot assure investors that we will be able to achieve the
technological advances to remain competitive and profitable, that new products
and services will be developed and manufactured on schedule or on a
cost-effective basis, that anticipated markets will exist or develop for new
products or services, or that any marketed product will not become
technologically obsolete.

We depend on key personnel in a competitive market for skilled employees, and
failure to retain and attract qualified personnel could substantially harm our
business.

      Our potential for success depends significantly on our executive officers,
including, Edward Staples, our President; Francis Chang, our Vice President,
Finance and Administration; and Teong Lim, our Vice President, Corporate
Development. These individuals do not have employment agreements with the
Company. We do not carry key-man life insurance on any executive. Given the
early stage of our product development and commercialization and our plans for
rapid expansion, the loss of the services of any executive or the services of
any other key employees we may hire in the future would have a substantial,
adverse effect on our business. We believe that our future success will depend
in large part on our ability to attract and retain highly skilled sales,
marketing and management personnel. If we are unable to hire the necessary
personnel, the development of our business will likely be delayed or prevented.
Competition for these highly skilled employees is intense. As a result, we
cannot assure you that we will be successful in retaining our key personnel or
in attracting and retaining the personnel we require for expansion.

We may not be able to protect our intellectual property and may infringe on the
intellectual property rights of others.

      The protection of our intellectual property, including our patents and
other proprietary rights, is important to our success and our competitive
position. Accordingly, we devote substantial resources to the maintenance and
protection of intellectual property through various methods such as patents and
patent applications, trademarks, copyrights, confidentiality and non-disclosure
agreements. We also rely on trade secrets, proprietary methodologies and
continuing technological innovation to remain competitive. We have taken
measures to protect our trade secrets and know-how, including the use of
confidentiality agreements with our employees. However, it is possible that
these agreements may be breached and that the available remedies for any breach
will not be sufficient to compensate us for damages incurred.

      We currently have four patents in the United States and patents in various
foreign countries. There can be no assurance that the claims allowed under any
patents held by us will be sufficiently broad to protect our technology against
competition from third parties with similar technologies or products. Moreover,
we cannot assure you that others will not assert rights in, or ownership of,
patents and other proprietary rights we may establish or acquire or that we will
be able to successfully resolve such conflicts. In addition, we cannot assure
you that any patents issued to us will not be challenged, invalidated or
circumvented or that the rights granted under these patents will provide a
competitive advantage to us. Moreover, the laws of some foreign countries do not
protect intellectual property rights to the same extent as the laws of the
United States, and we could experience various obstacles and high costs in
protecting our intellectual property rights in foreign countries. If we are
unable to obtain or maintain these protections, we may not be able to prevent
third parties from using our intellectual property.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

Our stock price is subject to extreme volatility.

      The trading price of our common stock is likely to be highly volatile and
could be subject to wide fluctuations in response to factors such as actual or
anticipated variations in the Company's quarterly operating results,
announcements of technological innovations, or new products by the Company or
its competitors, changes in financial estimates by securities analysts,
conditions or trends in the analytic instrumentation markets, changes in the
market valuations of other security-detection oriented companies, announcements
by the Company or its competitors of significant acquisitions, strategic
partnerships, joint ventures or capital commitments, additions or departures of
key personnel, sales of common stock or other securities of the Company in the
open market and other events or factors, many of which are beyond the Company's
control. Further, the stock markets in general, and the market for technology
companies have experienced extreme price and volume fluctuations that have often
been unrelated or disproportionate to the operating performance of such
companies. These broad market and industry factors may materially and adversely
affect the market price of the common stock, regardless of the Company's
operating performance. Market fluctuations, as well as general political and
economic conditions such as recession or interest rate or currency rate
fluctuations, may also adversely affect the market price of the common stock. In
the past, following periods of volatility in the market price of a company's
securities, securities class-action litigation has often been instituted against
such company. Such litigation, if instituted, could result in substantial costs
and a diversion of management's attention and resources, which would have a
material adverse effect on the Company's business, results of operations and
financial condition.


                                       13


There is no established trading market for our shares of common stock. The
liquidity of our common stock will be affected by its limited trading market.

      Bid and ask prices for our common stock are quoted on the Over-the-Counter
Bulletin Board under the symbol "ESNR.OB." There is currently no broadly
followed, established trading market for our common stock. An established
trading market for our shares may never develop or be maintained. Although we
intend, as soon as is practicable, to undertake the process to become listed on
one of the national stock exchanges or with Nasdaq, there is no assurance as to
when or if those events will occur. Active trading markets generally result in
lower price volatility and more efficient execution of buy and sell orders. The
absence of an active trading market reduces the liquidity of our shares. Prior
to the consummation of the merger, we had no reported trading volume in our
common stock. Since then, we have had sporadic reported trading in our shares.
As a result of this lack of trading activity, the quoted price for our common
stock on the Over-the-Counter Bulletin Board is not necessarily a reliable
indicator of its fair market value. Further, if we cease to be quoted, holders
would find it more difficult to dispose of, or to obtain accurate quotations as
to the market value of, our common stock, and the market value of our common
stock would likely decline.

If and when a trading market for our common stock develops, because we are a
technology company, we expect that the trading prices will be extremely
volatile.

      The trading prices of technology company stocks in general tend to
experience extreme price fluctuations. The valuations of many technology
companies without consistent product revenues or earnings, if any, are not based
on conventional valuation standards such as price to earnings and price to sales
ratios. Any negative change in the public's perception of the prospects of
technology companies could depress our stock price regardless of our results of
operations if a trading market for our stock develops. Other broad market and
industry factors may decrease the trading price of our common stock, regardless
of our performance. Market fluctuations, as well as general political and
economic conditions such as war, recession or interest rate or currency rate
fluctuations, also may decrease the trading price of our common stock. In
addition, our stock price could be subject to wide fluctuations in response to
factors including, but not limited to, the following:

      o     announcements of new technological innovations or new products by us
            or our competitors;

      o     conditions or trends in the sensor technology or chemical detection
            industry;

      o     changes in the market valuations of other technology companies;

      o     developments in domestic and international governmental policy or
            regulations;

      o     announcements by us or our competitors of significant acquisitions,
            strategic partnerships, joint ventures or capital commitments;

      o     developments in patent or other proprietary rights held by us or by
            others;

      o     loss or expiration of our intellectual property rights;

      o     lawsuits initiated by or against us;

      o     period-to-period fluctuations in our operating results;

      o     sales of our common stock or other securities in the open market.

      In the past, shareholders have often instituted securities class action
litigation after periods of volatility in the market price of a company's
securities. If a shareholder files a securities class action suit against us, we
would incur substantial legal fees and our management's attention and resources
would be diverted from operating our business to respond to the litigation.


                                       14


We may raise additional capital through a securities offering that could dilute
your ownership interest

      We require substantial working capital to fund our business. If we raise
additional funds through the issuance of equity, equity-related or convertible
debt securities, these securities may have rights, preferences or privileges
senior to those of the holders of our common stock. The issuance of additional
common stock or securities convertible into common stock by our management will
also have the effect of further diluting the proportionate equity interest and
voting power of holders of our common stock.

      In addition, under our Articles of Incorporation, the Board is authorized
to issue, without obtaining shareholder approval, shares of preferred stock
having the rights, privileges and designates as determined by the Board.
Therefore, the Board could issue shares of preferred stock that would have
preferential liquidation, distribution, voting, dividend or other rights, which
would be superior to the rights of common stockholders.

A significant number of our shares are eligible for sale, and their sale could
depress the market price of our common stock.

      Sales of a significant number of shares of our common stock in the open
market could harm the market price of our common stock. A reduced market price
for our shares could make it more difficult to raise funds through future
offerings of common stock. Approximately 27 million shares are eligible for
trading in the open market. As additional shares become available for resale in
the open market, including new shares issued upon the exercise of our
outstanding options, warrants, and contractual obligations to issue shares, the
number of our publicly tradable shares will increase, which could decrease their
trading price. In addition, some of our shares may be offered from time to time
in the open market pursuant to Rule 144, and these sales may have a depressive
effect on the market for our shares. In general, a person who has held
restricted shares for a period of one year may, upon filing with the SEC a
notification on Form 144 and satisfying certain other conditions to the
application of Rule 144, sell into the market shares up to an amount equal to 1%
of the outstanding shares of common stock. These sales may be repeated once each
three months. In addition, any of the restricted shares may be sold by a
non-affiliate after they have been held for two years pursuant to Rule 144(k).

We may be subject to the SEC's penny stock rules.

      Broker-dealer practices in connection with transactions in "penny stocks"
are regulated by certain rules adopted by the SEC. Penny stocks generally are
equity securities with a price of less than $5.00, other than securities
registered on certain national securities exchanges or quoted on the Nasdaq
Stock Market if current price and volume information with respect to
transactions in such securities is provided by the exchange or system. The rules
require that a broker-dealer, prior to a transaction in a penny stock not
otherwise exempt from the rules, deliver a standardized risk disclosure document
that provides information about penny stocks and the risks in the penny stock
market. The broker-dealer also must provide the customer with current bid and
offer quotations for the penny stock, the compensation of the broker-dealer and
its salesperson in connection with the transaction and monthly account
statements showing the market value of each penny stock held in the customer's
account. In addition, the rules generally require that prior to a transaction in
a penny stock, the broker-dealer must make a special written determination that
the penny stock is a suitable investment for the purchaser and receive the
purchaser's written agreement to the transaction. These disclosure requirements
may have the effect of reducing the liquidity of penny stocks. If our securities
become subject to the penny stock rules, holders of our shares of common stock
may find it more difficult to sell their securities.

We have not paid dividends in the past and do not expect to pay dividends in the
future. Any return on investment may be limited to potential future appreciation
in the value of our stock.

      We have never paid cash dividends on our stock and do not anticipate
paying cash dividends on our stock in the foreseeable future. The payment of
dividends on our shares, if ever, will depend on our earnings, financial
condition and other business and economic factors affecting us at such time as
the board of directors may consider relevant. If we do not pay dividends, our
stock may be less valuable because a return on investment will only occur if and
to the extent that our stock price appreciates, and if the price of our stock
does not appreciate, then there will be no return on investment.

Our anti-takeover defense provisions may deter potential acquirers and depress
our stock price.

      Certain provisions of our articles of incorporation, bylaws and Nevada
law, as well as certain agreements we have with our executives, could be used by
our incumbent management to make it substantially more difficult for a third
party to acquire control of us. These provisions include the following:


                                       15


      o     we may issue preferred stock with rights senior to those of our
            common stock;

      o     our Board of Directors has the exclusive right to fill vacancies and
            set the number of directors;

      o     we require advance notice for nomination of directors by our
            shareholders and for shareholder proposals.

      These provisions may discourage certain types of transactions involving an
actual or potential change in control. These provisions may also limit our
shareholders' ability to approve transactions that they may deem to be in their
best interests and discourage transactions in which our shareholders might
otherwise receive a premium for their shares over the then current market price.

Some of our existing shareholders can exert control over us, and may not make
decisions that are in the best interests of all shareholders.

      Our officers, directors and principal shareholders together control
approximately 42% of our outstanding common stock. Land & General Berhad through
its wholly owned subsidiary, L & G Resources (1994), Inc., owns approximately
18.3% of our outstanding common stock. As a result, these shareholders, if they
act together, will be able to exert a significant degree of influence over our
management and affairs and over matters requiring shareholder approval,
including the election of directors and approval of significant corporate
transactions. In addition, this concentration of ownership may delay or prevent
a change in control of us and might affect the market price of our shares, even
when a change may be in the best interests of all shareholders. Moreover, the
interests of this concentration of ownership may not always coincide with our
interests or the interests of other shareholders, and, accordingly, they could
cause us to enter into transactions or agreements which we would not otherwise
consider.

Past activities of the Company and its affiliates may lead to future liability
for us.

      Prior to the acquisition of ELP, we engaged in businesses unrelated to its
current operations. As a result, liabilities of the prior business before to the
acquisition of ELP may have a material adverse effect on us.

Item 3. Controls and Procedures

      Within 90 days prior to the date of this Form 10-QSB, the Company carried
out an evaluation, under the supervision and with the participation of the
Company's management, including the Company's President and Chief Executive
Officer along with the Company's Chief Financial Officer, of the effectiveness
of the design and operation of the Company's disclosure controls and procedures
pursuant to Exchange Act Rule 13a-14. Based upon that evaluation, the Company's
President and Chief Executive Officer along with the Company's Chief Financial
Officer concluded that the Company's disclosure controls and procedures are
effective in timely alerting them to material information relating to the
Company required to be included in this Form 10-QSB.

      There have been no changes in the Company's internal controls or in other
factors, which could significantly affect the internal controls subsequent to
the date the Company carried out its evaluation.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

      We are not a party to any pending material legal proceedings and are not
aware of any threatened or contemplated proceeding by any governmental authority
against us.

Item 2. Changes in Securities and Use of Proceeds.

      During the first quarter ended March 31, 2005, the Company issued
unregistered common stock and various warrants as outlined below:

      The Company issued 20,000,000 shares of its common stock on February 1,
2005 in connection with the acquisition of the sole shareholders of Electronic
Sensor Technology, LP, a California limited partnership.


                                       16


      As of February 1, 2005, the Company issued 3,985,000 shares of its common
stock and warrants to purchase 3,985,000 shares of its common stock at an
exercise price of $1.00 per share for three years to certain investors. The
Company received gross proceeds of $3,985,000. In addition, certain bridge
investors of Electronic Sensor Technology, LP ("LP"), exchanged Class C
Partnership Interests in the LP for 200,000 shares of Company common stock and
200,000 Investor Warrants.

      The Company also issued 2,783,741 shares of its common stock and warrants
to purchase 1,391,871 shares of its common stock at an exercise price of $1.00
per share for three years, so long as the trading price of the stock was at
least $1.50 per share ("Debtholder Warrants") in exchange for cancellation of
certain debt by LP debt holders.

      The Company relied upon Section 4(2) of the Securities Act for the above
listed offers and sales. It believed that Section 4(2) was available because the
offers and sales did not involve a public offering and there was not general
solicitation or general advertising involved in suxh offers or sales.

Item 3. Defaults Upon Senior Securities

There were no defaults upon senior securities.

Item 4. Submission of Matters to a Vote of Security Holders

There were no matters submitted to the vote of security holders.

Item 5. Other Information

There is no other information to report
