----------
* We were not required to file reports pursuant to Section 13 or 15(d) of the
Securities Exchange Act during the past 12 months because (i) our registered
common stock was registered under the Securities Act during such period and was
not registered under the Exchange Act, (ii) we did not have any registration
statement that became effective during such period and (iii) we had less than
300 shareholders of record throughout such period. Although we were not required
to do so, we voluntarily filed such reports with the Securities and Exchange
Commission during such period. On March 24, 2006 we filed a registration
statement on Form 10-SB to register our common stock pursuant to the Exchange
Act, which we subsequently withdrew pursuant to the request of the Securities
and Exchange Commission until our registration statement on Form SB-2, for which
an amendment was last filed on May 1, 2006, is declared effective. Once our
registration statement on Form SB-2 is declared effective, we plan to file
another registration statement on Form 10-SB to register our common stock
pursuant to the Exchange Act. Once our registration statement on Form 10-SB is
effective, we will be subject to the filing requirements of the Securities
Exchange Act.

                       ELECTRONIC SENSOR TECHNOLOGY, INC.
                          Notes to Financial Statements
                                   (Unaudited)
                                  June 30, 2006

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-B. 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,
     2005, included in the Annual Report filed on Form 10-KSB for the year then
     ended, which will be amended and such financial statements restated in
     accordance with the Current Report filed on Form 8-K on August 14, 2006.

     In the opinion of the management of Electronic Sensor Technology, Inc. (the
     "Company"), all adjustments (consisting of normal recurring accruals)
     necessary to present fairly the Company's financial position as of June 30,
     2006, and the results of operations and cash flows for the six-month period
     ending June 30, 2006 have been included. The results of operations for the
     six-month period ended June 30, 2006 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 Annual Report filed on Form 10-KSB as filed with the Securities
     and Exchange Commission for the year ended December 31, 2005, which will be
     amended and such financial statements restated in accordance with the
     Current Report filed on Form 8-K on August 14, 2006.

2)   RESTATEMENT OF JUNE 30, 2005 FINANCIAL STATEMENTS

     On August 14, 2006 and March 17, 2006, we filed Current Reports on Form 8-K
     stating that the financial statements contained in our Quarterly Report on
     Form 10-QSB for the interim period ended June 30, 2005 (in addition to the
     financial statements for the fiscal year ended December 31, 2005 and the
     interim periods ended March 31, 2005, September 30, 2005 and March 31,
     2006) should not longer be relied upon as we did not properly account for
     certain liquidated damages associated with a $3.985 million private
     placement of warrants and shares of our common stock that occurred in
     February 2005. In determining the proper accounting for the liquidated
     damages, we are considering the guidance contained in Emerging Issue Task
     Force ("EITF") 05-04 View C, "The Effect of a Liquidated Damages Clause on
     a Freestanding Financial Instrument", subject to EITF Issue No. 00-19,
     "Accounting for Derivative Financial Instruments Indexed to, and
     Potentially Settled in, a Company's Own Stock". The restated amounts
     presented in this Quarterly Report and contained on the Consolidated
     Statement of Operations reflects the balances for "Other income-derivative"
     and "Other expense-derivative" for the three- and six-month periods ended
     June 30, 2005, in accordance with the foregoing. Correspondingly, the
     restated amount on the Consolidated Statement of Cash Flows properly
     reflects the amount related to the fair value of derivative liabilities for
     the six-months period ended June 30, 2005. See Note 6 - Derivative
     Liabilities, for further information on the accounting and measurement of
     the derivative liabilities associated with the February 2005 private
     placement of warrants and shares of our common stock, as well as those
     associated with the December 2005 private placement of warrants and
     convertible debentures, and related agreements.

3)   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. 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

                                      F-4


     subsidiary of Bluestone on January 31, 2005. Under the Merger Agreement (i)
     AAC merged with and into Amerasia such that Amerasia became of 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.

     For accounting purposes, the transaction was treated as a recapitalization
     of EST and accounted for as a reverse acquisition. Accordingly, the
     accompanying financial statements include the accounts of EST for the
     period from January 1, 2005 to June 30, 2006 and the accounts of Bluestone
     from February 1, 2005 to June 30, 2006.

4)   NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a)   NATURE OF BUSINESS

          The Company develops and manufactures electronic devices used for
          vapor analysis. It markets its products through distribution channels
          in over 20 countries.

     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.

     c)   LINE OF CREDIT

          The Company has a revolving line of credit agreement for borrowings up
          to $500,000. The line of credit is secured and collateralized with a
          certificate of deposit in the amount of $250,000. The line of credit
          had borrowings of $370,000 against it at June 30, 2006. The line of
          credit expires on March 31, 2007.

     d)   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 shipment or
          service revenue are recorded as deferred revenue.

     e)   SHIPPING AND HANDLING

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

     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)   DEFERRED FINANCING COSTS

          Deferred financing costs consist of direct costs incurred by the
          Company in connection with the issuance of its 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.

                                      F-5


     h)   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.

     i)   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.

     j)   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.

     k)   FAIR VALUE OF FINANCIAL INSTRUMENTS

          The fair value of certain financial instruments, including accounts
          receivable, accounts payable and accrued liabilities, approximate
          their carrying values due to the short maturity of these instruments.
          The fair value of the convertible debentures issued by the Company in
          December 2005 amounts to $7,000,000, based on the Company's
          incremental borrowing rate. The carrying value of the derivative
          liabilities associated with the convertible debentures represents its
          fair value.

     l)   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 June 30, 2006
          no assets were impaired.

     m)   DERIVATIVE LIABILITIES

          The Company accounts for its liquidated damages granted pursuant to a
          separate registration rights agreement pursuant to Emerging Issue Task
          Force ("EITF") 05-04, View C, "The Effect of a Liquidated Damages
          Clause on a Freestanding Financial Instrument", subject to EITF Issue
          No. 00-19, "Accounting for Derivative Financial Instruments Indexed
          to, and Potentially Settled in, a Company's Own Stock". Pursuant to
          EITF 05-04, View C, liquidated damages payable in cash or stock are
          accounted for as a separate derivative, which requires a periodical
          valuation of its fair value and a corresponding recognition of
          liabilities associated with such derivative.

          The Company accounts for liquidated damages granted pursuant to
          registration rights which are not included in a separate registration
          right agreement as a combined unit with the warrants which are
          contemporaneously issued with the registration rights pursuant to SFAS
          133 "Accounting for Derivative and Hedging Activities" and EITF 00-19.

          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, at issuance and at each
          subsequent balance sheet date, and a corresponding recognition of
          liabilities associated with such derivatives. The

                                      F-6


          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.

          Embedded conversion features represent embedded derivatives which are
          separated from their host and accounted for as derivatives. An
          embedded derivative instrument may consist of:

               1)   The underlying is an interest rate that alters net interest
                    payments such that they could at least double the investor's
                    initial rate of return on the host contract, such as an
                    interest bearing debenture, and that is at least twice what
                    would otherwise be the market return for a contract that has
                    the same terms as the host contract and that involves a
                    debtor with similar credit quality;

               2)   The underlying is a an debt instrument which provides for
                    non-standard anti-dilution provisions upon conversion of a
                    debt instrument into equity, such as anti-dilution
                    provisions which reset to a lower conversion price than
                    initially stated in the debt instrument in the event of a
                    subsequent financing with a lower effective price which
                    classify the debt instrument as non-conventional debt;

               3)   The underlying is a debt instrument which provides for
                    variable number of shares upon conversion of a debt
                    instrument into equity;

               4)   The underlying is an instrument which provides for
                    acceleration of the repayment of a principal on a debt
                    instrument that requires principal repayments if the debt
                    involves a substantial premium and the acceleration is only
                    contingently exercisable and is not indexed to interest
                    rates or credit risk.

          Freestanding warrants may be recorded as derivative liabilities if
          they allow for net-cash settlement or if they give the counterparty a
          choice of net-cash or physical settlement or would not qualify for the
          following conditions for equity classification, among others:

               1)   The Company does not have sufficient authorized and unissued
                    shares available to settle the contract after considering
                    all other commitments that may require the issuance of stock
                    during the maximum period the derivative contract could
                    remain outstanding;

               2)   The contract does not contain an explicit limit on the
                    number of shares to be delivered in a share settlement;

               3)   The contract provides for cash payments to the counterparty
                    in the event the Company fails to make timely filings with
                    the SEC.

          In June 2005, the Financial Accounting Standard Board issued EITF
          05-04. EITF 05-04 addresses the question as to whether liquidated
          damages pursuant to a registration rights agreement should be combined
          as a unit with the underlying financial instruments and be evaluated
          as a single instrument. EITF 05-04 does not reach a consensus on this
          matter and allows for the treatment as a combined unit (Views A and B)
          as well as separate freestanding financial instruments (View C). On
          September 15, 2005, the FASB staff postponed further discussion of
          EITF 05-04. As of May 31, 2006, the FASB still has not rescheduled
          EITF 05-04 for further discussion.

                                      F-7


          In connection with the issuance of a convertible debentures and
          related warrants, we granted liquidated damages pursuant to a separate
          registration right agreement. The Company adopted View C of EITF
          05-04. Accordingly, the liquidated damages pursuant to this
          registration right agreement were evaluated as a stand alone financial
          instrument. This treatment did not have a significant different effect
          than if the Company would have adopted View A or B, because the
          classification of the warrants and certain embedded features of the
          convertible debentures were classified as derivative liabilities. The
          Company believes that should the FASB staff reach a consensus on EITF
          05-04 and select combined treatment (View A or B), the embedded
          conversion features and the warrants will have to be evaluated as a
          combined unit with the liquidated damages pursuant to the registration
          rights agreement, and accordingly, be evaluated as derivative
          liabilities. The Company does not believe that its measurement of the
          derivative liabilities under View A or View B would significantly
          differ from its measurement of the derivative liabilities under View C
          in these circumstances.

          The classification of each contract (e.g., embedded conversion
          feature, liquidated damage, freestanding warrant) is reassessed at
          each balance sheet date. If the classification required under EITF
          00-19 changes as a result of events during the period (if, for
          example, as a result of issuing an instrument which is convertible
          into an undeterminable amount of shares we cannot ascertain that we
          have a sufficient amount of authorized but unissued shares to satisfy
          the maximum number of shares that could be required to net-share
          settle the contract), the contract is reclassified as of the date of
          the event that caused the reclassification. If a contract is
          reclassified from permanent or temporary equity to an asset or
          liability, the change in fair value of the contract during the period
          the contract was classified as equity is accounted for as an
          adjustment to stockholders' equity. The contract is subsequently
          marked to fair value through earnings. If a contract is reclassified
          from an asset or a liability to equity, gains or losses recorded to
          account for the contract at fair value during the period that the
          contract was classified as asset or liability is not reversed.

          Additionally, because there is no explicit number of shares that are
          to be delivered upon satisfaction of the liquidated damages, the
          Company is unable to assert that it had sufficient authorized and
          unissued shares to settle the liquidated damages. Accordingly, all of
          the Company's previously issued and outstanding instruments, such as
          warrants and options as well as those issued in the future, would be
          classified as liabilities as well, effective with the granting of the
          registration rights

     n)   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 using the weighted average number of common and dilutive
          common share equivalents outstanding during the period. Dilutive
          common share equivalents consist of shares issuable upon the exercise
          of stock options and warrants embedded conversion features (calculated
          using the reverse treasury stock method). The outstanding options,
          warrants and shares equivalent issuable pursuant to embedded
          conversion features amounted to 66,982,944 and 5,576,871 at June 30,
          2006 and 2005, respectively. The outstanding options, warrants and
          shares equivalent issuable pursuant to embedded conversion features
          and warrants at June 30, 2006 and 2005, respectively, are excluded
          from the loss per share computation for that period due to their
          antidilutive effect.

                                      F-8


          The following sets forth the computation of basic and diluted earnings

     o)   STOCK BASED COMPENSATION

          In December 2004, the FASB issued SFAS No. 123(R), "Share-Based
          Payment," which replaces SFAS No. 123 and supersedes APB Opinion No.
          25. Under SFAS No. 123(R), companies are required to measure the
          compensation costs of share-based compensation arrangements based on
          the grant-date fair value and recognize the costs in the financial
          statements over the period during which employees are required to
          provide services. Share-based compensation arrangements include stock
          options, restricted share plans, performance-based awards, share
          appreciation rights and employee share purchase plans. In March 2005
          the SEC issued Staff Accounting Bulletin No. 107, or "SAB 107". SAB
          107 expresses views of the staff regarding the interaction between
          SFAS No. 123(R) and certain SEC rules and regulations and provides the
          staff's views regarding the valuation of share-based payment
          arrangements for public companies. SFAS No. 123(R) permits public
          companies to adopt its requirements using one of two methods. On April
          14, 2005, the SEC adopted a new rule amending the compliance dates for
          SFAS 123R. Companies may elect to apply this statement either
          prospectively, or on a modified version of retrospective application
          under which financial statements for prior periods are adjusted on a
          basis consistent with the pro forma disclosures required for those
          periods under SFAS 123. Effective January 1, 2006, the Company has
          fully adopted the provisions of SFAS No. 123R and related
          interpretations as provided by SAB 107. As such, compensation cost is
          measured on the date of grant as the excess of the current market
          price of the underlying stock over the exercise price. Such
          compensation amounts, if any, are amortized over the respective
          vesting periods of the option grant. The Company applies this
          statement prospectively.

5)   CONVERTIBLE DEBENTURES

     During December 2005, we issued in a private offering, $7,000,000 aggregate
     principal amount of convertible debentures due December 7, 2009. The
     convertible debentures are 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 and can be redeemed at the lesser of $0.4544 or 90% of the
     average of the volume weighted average price for the 20 consecutive trading
     days immediately prior to the conversion date. The Company received
     $7,000,000 in cash as consideration. The convertible debentures bear
     interest at 8%, payable in cash or stock, at the Company's option, and are
     required to be redeemed in 9 equal quarterly payments commencing January 1,
     2008, in cash or stock, at the Company's option. If the Company chooses to
     pay interest on or redeem the debentures in shares of the Company's common
     stock, rather than in cash, the conversion rate for such

                                      F-9


     stock payment is the lesser of $0.4544 and 90% of the average of the volume
     weighted average price for the 20 consecutive trading days immediately
     prior to the interest payment or redemption date, as applicable.

     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. Furthermore, the Company granted
     liquidated damages pursuant to a registration rights agreement.

     The convertible debentures and related agreements provide, among other
     things, for:

          1)   Liquidated damages amounting to 2% per month of the outstanding
               principal amount, payable in cash or stock, to the debenture
               holders in the event that a registration statement covering the
               shares underlying the convertible debentures is not declared
               effective within 150 days of the date the debentures were issued
               (although a registration statement covering the shares underlying
               the convertible debentures has not been declared effective as of
               June 30, 2006, no claims for liquidated damages have been
               received from the debenture holders). The liquidated damages are
               payable in cash monthly or if unpaid, bear interest at 18% per
               annum. If unpaid by January 1, 2008 and thereafter, they may be
               converted in shares of common stock at the same prevailing rate
               as the remaining principal amount of the convertible debentures;

          2)   Default interest rate of 18% and a default premium of 30% of the
               principal amount of the debentures, payable in cash or stock.
               Events of default include, among other things, if a payment,
               whether cash or stock is not paid on time and cured within three
               days, if the Company's common stock is not quoted for trading for
               at least five trading days, if a registration is not effective
               within 180 days after December 7, 2005 (although a registration
               statement covering the shares underlying the convertible
               debentures has not been declared effective as of June 30, 2006,
               no claims for liquidated damages have been received from the
               debenture holders). The default interest rate and the default
               premium may be converted in shares of common stock at the same
               prevailing rate as the remaining principal amount of the
               convertible debentures;

          3)   A reset feature of the conversion price in the event of a
               subsequent equity or convertible financing with an effective
               price lower than the debenture conversion price, whereby the
               aforementioned variable conversion price of the convertible
               debentures is adjusted to the new lower effective price of the
               subsequent equity or convertible financing;

          4)   The warrants require that the Company reimburse any holder of a
               warrant in respect of any trading loss resulting from the failure
               of the Company to timely deliver shares issued pursuant to the
               exercise of warrants. This compensation may be paid in shares of
               common stock or cash. The exercise price of the warrants, which
               is $0.4761 per share at the date of the agreement, may be reduced
               to $0.001 per share, at a monthly rate $0.03 per share if the
               registration statement we are required to file at the request of
               the warrant holders with respect to the common stock underlying
               the warrants is not declared effective within six months of the
               date of issuance of the warrants.

     In connection with the issuance of the convertible debentures, we issued
     485,213 warrants to a company in partial consideration for financial
     advisory services, as well as paid $490,000 to this company. The warrants
     have the same terms as those granted to the debenture holders. The fair
     value of the warrants at the date of issuance amounted to approximately
     $136,000. We also incurred approximately $102,500 in additional
     professional fees 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 have been recorded as deferred
     financing costs. The deferred financing costs are amortized over the term
     of the convertible debentures. The amortization of deferred financing costs
     approximated $121,000 at June 30, 2006.

     See Note 6 - Derivative Liabilities for further information on the
     accounting and measurement of the derivative liabilities associated with
     the issuance of the convertible debentures and related agreements.

                                      F-10


     We recognized a debt discount of $7,000,000 at the date of issuance of the
     convertible debentures and the excess amount has been recorded as liability
     and a corresponding increase to other expense. The debt discount is
     recognized over the term of the convertible debentures.

6)   DERIVATIVE LIABILITIES

     FEBRUARY 2005 TRANSACTION

     During February 2005, we recognized derivative liabilities of approximately
     $6.0 million pursuant to the issuance of 3,985,000 freestanding warrants
     and granting certain registration rights which provided for liquidated
     damages in the event of failure to timely register the shares in connection
     with the issuance of shares of common stock and the related warrants.

     There are no liquidated damages provided for untimely effectiveness of the
     registration of shares pursuant to piggy-back registration rights. The
     Company intends to register all shares and warrants pursuant to the
     subscriber piggy-back registration rights.

     The agreement pursuant to which the warrants were issued and the
     registration rights were granted provided for liquidated damages pursuant
     to demand registration rights in the event of a failure to timely register
     the shares after demand is made by the holders of a majority of the
     warrants and shares of common stock issued pursuant to such agreement. The
     demand registration rights of these investors are such that if the Company
     fails to register the investors shares, including the shares underlying the
     warrants, the Company will pay a cash penalty amounting to 1% of the amount
     invested per month, $39,850, if the registration statement is not filed
     within 60 days of demand or is not declared effective within 150 days from
     the date of initial filing. The maximum liability associated with the
     liquidated damages amounts to 49% of the gross proceeds associated with the
     issuance of shares of common stock, which amounts to $1,952,650. The
     percentage of liquidated damages amounts to the difference between 60
     months, which is the inherent time limitation under which the underlying
     shares would be free-trading (three year term and two year holding period)
     and 11 months, which is the grace period for registering the shares (no
     demand permitted for four months, two-month period to file and five-month
     period to become effective), times the penalty percentage, which is 1%. The
     Company believes that the likelihood that it will incur any liabilities
     resulting from the liquidated damages pursuant to the demand registration
     rights is remote considering that it will register the shares and the
     shares underlying the warrants pursuant to piggy-back registration rights,
     which do not contain liquidated damages.

     Because the registration rights were not granted under a separate
     registration rights agreement, we considered those features in evaluating
     whether the associated warrants should be classified as derivative
     liabilities. Considering that the amount of the maximum penalty is 49%, the
     Company cannot conclude that that this discount represents a reasonable
     approximation of the difference between registered and unregistered shares
     under paragraph 16 of EITF 00-19. Accordingly, the warrants issued in
     connection with the February 2005 transaction are considered derivative
     liabilities.

     The fair value of the warrants issued in connection with the February 2005
     transaction at the date of issuance of the warrants and the granting of
     registration rights and at June 30, 2006 is as follows:

     DECEMBER 2005 TRANSACTION

     During December 2005, in connection with the issuance of the convertible
     debentures, 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.

     The  embedded conversion features are as follows:

     Default Interest Rate and Premium: The default interest rate is 18% while
     the stated rate of the convertible debentures is 8%. Additionally, the
     Company is liable to pay for a premium amounting to 30% of the principal
     amount of the convertible debentures in the event of default. This embedded
     derivative could at least double the investor's initial rate of return on
     the host contract and could also result in a rate of return that is at
     least twice what otherwise would be the market return for a contract that
     has the same terms as the host contract and that involves a debtor with
     similar credit quality. Furthermore, the default interest rate may be
     triggered by certain events of defaults which are not related to
     credit-risk-related covenants or the Company's creditworthiness (e.g., if a
     registration statement is not effective within 180 days after December 7,
     2005). The default provisions are effective, at the holders' option, upon
     an event of default. Although a registration statement covering the shares
     underlying the convertible debentures has not been declared effective as of
     June 30, 2006, the debenture holders have not notified the Company of an
     election to accelerate the debentures, nor have any claims for liquidated
     damages been received.

     Reset Feature Following Subsequent Financing: The debenture provides for a
     reset feature of the conversion price in the event of a subsequent equity
     or convertible financing with an effective price lower than the debenture
     conversion price, whereby the aforementioned variable conversion price of
     the convertible debentures is adjusted to the new lower effective price of
     the subsequent equity or convertible financing , which amounts to 10% of
     the shares issuable pursuant to the convertible debentures, which is the
     effective discount to market value we would offer in the event we provide
     for a subsequent private placement financing. This reset does not
     constitute a standard anti-dilution provision and is indexed to an
     underlying other than an interest rate or credit risk.

     Conversion Rate: The convertible debentures are convertible at a variable
     conversion price, which is the lesser of $0.4544 or 90% of the average of
     the volume weighted average price for the 20 consecutive trading days
     immediately prior to the conversion date. The convertible debentures are
     convertible at any time on or prior to the maturity date at the option of
     the debenture holder. The implied conversion embedded feature amounts to a
     conversion discount of 10% to market.

                                      F-12


     The Company believes that the aforementioned embedded derivatives meet the
     criteria of SFAS 133, including Implementation issue No. B16 and EITF
     00-19, when appropriate, and should be accounted for as derivatives with a
     corresponding value recorded as a liability.

     In connection with the issuance of the convertible debentures, the Company
     issued warrants to the debenture holders. The related warrants require that
     the Company reimburse any holder of a warrant in respect of any trading
     loss resulting from the failure of the Company to timely deliver shares
     issued pursuant to the exercise of warrants. This compensation may be paid
     in shares of common stock or cash. Accordingly, we have accounted for such
     warrants as derivatives.

     In connection with the issuance of the convertible debentures, the Company
     granted liquidated damages pursuant to a registration rights agreement. The
     liquidated damages amount to 2% per month of the outstanding principal
     amount, payable in cash or stock, to the debenture holders in the event
     that a registration statement covering the shares underlying the
     convertible debentures is not declared effective within 150 days of the
     date the debentures were issued (although a registration statement covering
     the shares underlying the convertible debentures has not been declared
     effective as of June 30, 2006, no claims for liquidated damages have been
     received from the debenture holders). The liquidated damages are payable in
     cash monthly or if unpaid, bear interest at 18% per annum. If unpaid by
     January 1, 2008 and thereafter, they may be converted in shares of common
     stock at the same prevailing rate as the remaining principal amount of the
     convertible debentures. Pursuant to View C of EITF 05-04 the liquidated
     damages are accounted for as a separate derivative. While the liquidated
     damages may be settled in stock if unpaid by January 1, 2008, the Company
     determined that it was more likely that they would be paid in cash shortly
     after their occurrence and has used such assumption in measuring the fair
     value of the derivative liability associated with the liquidated damages.

     Additionally, because there is no explicit number of shares that are to be
     delivered upon satisfaction of the convertible debentures, the Company is
     unable to assert that it had sufficient amount of authorized and unissued
     shares to settle its obligations under the convertible debentures.
     Accordingly, all of the Company's previously issued and outstanding
     instruments, such as warrants, as well as those issued in the future, would
     be classified as liabilities as well, effective with the issuance of the
     convertible debentures and until the Company is able to assert that it has
     a sufficient amount of authorized and unissued shares to settle its
     obligations under all outstanding instruments. At the date of the issuance
     of the convertible debentures, the Company had 1,941,871 warrants
     outstanding which were classified as derivatives.

     The fair value of the derivative liabilities at the date of issuance of the
     convertible debentures and at June 30, 2006 are as follows:

                                       At Issuance      At June 30, 2006
                                   ------------------  ------------------
     Freestanding warrants               $  3,532,348        $    756,932
     Embedded conversion features           3,463,542           4,359,649
     Liquidated damages                       192,500             192,500
     Other outstanding warrants               143,268                   0

     The Company used the following methodology to value the embedded conversion
     features and liquidated damages:

     It estimated the discounted cash flows payable by the Company, using
     probabilities and likely scenarios, for event of defaults triggering the
     30% penalty premium and 18% interest accrual, subsequent financing reset,
     and liquidated damages, such as the untimely effectiveness of a
     registration statement. If the additional cash consideration was payable in
     cash or stock, it determined the amount of additional shares that would be
     issuable pursuant to its assumptions. The Company will revisit the weight
     of probabilities and the likelihood of scenarios at each of the measurement
     dates of the derivative liabilities, which are the balance sheet dates.

                                      F-13


     The Company used the following assumptions to measure the identified
     derivatives, using the Lattice valuation model, as follows:

     Embedded conversion features

                                  At issuance      At June 30, 2006

     Market price:                  $    0.4880        $        0.19
     Conversion price:              $    0.4544        $        0.17
     Term:                              4 years           3.42 years
     Volatility:                             39%                  39%
     Risk-free interest rate:              4.39%                5.13%

     Freestanding warrants

     The derivative liability amounts to the fair value of the warrants issuable
     upon exercise, assuming that the underlying shares will not be timely
     registered. We computed the fair value of this embedded derivative using
     the Black Scholes valuation model with the following assumptions:

                                  At issuance      At June 30, 2006
                                ---------------   ------------------
     Market price:                  $     0.488        $        0.19
     Exercise price:                $    0.4761        $        0.34
     Term:                              5 years           4.42 years
     Volatility:                             39%                  39%
     Risk-free interest rate:              4.39%                5.13%

     We adjusted the effective exercise price to reflect the contractual
     adjustment assuming that the warrants will most likely be registered during
     the fourth quarter of 2006.

     Liquidated damages

     The liquidated damages, payable in cash, are valued using the weighting
     probabilities and likely scenarios to estimate the amount of liquidated
     damages and were valued at approximately $192,500 at the date of the grant
     of the registration rights and at June 30, 2006.

     The aggregate fair value of the derivative liabilities associated with the
     warrants, embedded conversion features, and liquidated damages in
     connection with the issuance of the convertible debentures and related
     agreements amounted to approximately $7.05 million at the date of issuance
     which exceeded the principal amount of the convertible debentures by
     approximately $50,000. The Company recognized $7,000,000 as debt discount
     and the excess amount has been recorded as other expenses. Additionally,
     approximately $136,000 of the fair value of the warrants was recorded as
     deferred financing costs.

     The aggregate fair value of all derivative liabilities upon issuance of the
     various debt and equity instruments amounted to $13.3 million, of which
     $10.7 million was allocated to the net proceeds of the issuance of common
     stock and convertible debentures, $2.4 million was allocated to other
     expenses and approximately $136,000 was allocated to deferred financing
     costs.

     The decrease in fair value of the derivative liabilities between
     measurement dates, which are the date of issuance of the various debt and
     equity instruments and the balance sheet date, which is June 30, 2006
     amounted to approximately $8.7 million and has been recorded as other
     income.

7)   STOCKHOLDERS' DEFICIT

     COMMON STOCK

     Shares issued pursuant to services

     During January 2006, the Company issued 75,000 shares to its former chief
     executive officer for services rendered. The fair value of such shares
     amounted to approximately $21,000 based on the quoted price of the
     Company's shares at the date of issuance.

     Conversion of shares for pre-merger liabilities

     In connection with the Mergers, the Company issued, in aggregate, 2,783,892
     shares of common stock in satisfaction of liabilities incurred pursuant to
     notes payable, loan payable, and related accrued interest to related
     parties.

     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 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

                                      F-15


     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.

     All options outstanding at June 30, 2006 were fully-vested at January 1,
     2006, with the exception of 500,000 options held by our former Chief
     Executive Officer, Matthew Collier, and 250,000 options held by the
     Chairman of our Board of Directors, James Frey. Upon the termination of our
     Chief Executive Officer in January 2006, 200,000 of his options vested, but
     were cancelled, without being exercised, in April 2006. However, such
     options were cancelled, without being exercised, in April 2006.
     Accordingly, no expense associated with the outstanding options was
     recorded during the six-month period June 30, 2006.

OVERVIEW

The Company is engaged in the development, manufacturing, and sales of a
patented product called zNose(R); a device designed to detect and analyze
chemical odors and vapors, or, in other 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, environmental and laboratory instrumentation markets. The Company is
involved in ongoing product research and development efforts in that regard. The
Company has also concentrated its efforts on further product development,
testing and proving and assembling a sales and support organization.

The Company was originally incorporated under the laws of the state of Nevada as
"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 Ontario, Canada. Upon acquisition of Electronic Sensor
Technology, L.P. ("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, as discussed in the footnotes to the
financial statements, 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.

CRITICAL ACCOUNTING POLICIES

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

                                        2


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.

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 June 30, 2006 no assets were impaired.

The Company accounts for liquidated damages granted pursuant to a separate
registration rights agreement pursuant to Emerging Issue Task Force ("EITF")
05-04, View C, "The Effect of a Liquidated Damages Clause on a Freestanding
Financial Instrument", subject to EITF Issue No. 00-19, "Accounting for
Derivative Financial Instruments Indexed to, and Potentially Settled in, a
Company's Own Stock". Pursuant to EITF 05-04, View C, liquidated damages payable
in cash or stock are accounted for as a separate derivative, which requires a
periodical valuation of its fair value and a corresponding recognition of
liabilities associated with such derivative. The Company accounts for liquidated
damages granted pursuant to registration rights which are not included in a
separate registration right agreement as a combined unit with the warrants which
are contemporaneously issued with the registration rights pursuant to SFAS 133,
"Accounting for Derivative and Hedging Activities" and EITF 00-19. The Company
also 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. The valuation of such
derivatives requires significant judgment. We exercise our judgment in
determining the maximum liabilities associated with such derivatives as well as
the expected volatility related to their fair value. We base our estimate of the
maximum liabilities on our interpretation of the agreements related to the
derivatives.

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.

The terms of the convertible debentures and warrants that we issued in a private
placement on December 7, 2005 required that we register the shares of our common
stock underlying such debentures and warrants within 180 days of the date of
issuance of the debentures and warrants, as described more fully in the notes to
the consolidated

                                        3


financial statements contained in this Quarterly Report. The failure to do so is
an event of default under the debentures, giving the debenture holders the right
to accelerate the debentures and receive a premium of approximately 30% of the
outstanding amounts due under the debentures upon acceleration. The failure to
do so also reduces the exercise price of the warrants by $0.03 per month until
such registration statement is declared effective. In addition, the failure to
register such shares within 150 days of the date of issuance of the debentures
and warrants gives the holders the right to receive liquidated damages in the
amount of 2% per month of the purchase price of the debentures and warrants,
pursuant to a registration rights agreement, and the failure to pay such
liquidated damages relating to the debentures is an event of default under the
debentures. Although we have been working diligently to obtain effectiveness of
our registration statement and continue to do so, we have thus far been unable
to have such registration statement declared effective by the Securities and
Exchange Commission. As such, the aforementioned penalties have been triggered.

At this time, the holders of the debentures and the warrants have the right to
declare an acceleration of debentures and to receive a premium thereon. If the
holders do so, we will owe them approximately $9.1 million, due and payable
immediately upon such declaration by the holders. Under the terms of the
warrants, the exercise prices of the warrants would have fallen from $0.4761 per
share to approximately $0.4061 per share. Pursuant to the registration rights
agreement, we would also owe the holders of the debentures and warrants
approximately $466,000, plus interest thereon at a rate of 18% per annum. As of
the present date, the holders of the debentures and warrants have not declared
an event of default under the debentures, nor have they made any demand for
payment of liquidated damages (although such demand is not required for the
latter). We are currently in settlement negotiations for the forbearance of the
exercise of the foregoing rights by the holders.

RESULTS OF OPERATIONS

The following tables sets forth, in $ and as a percentage of revenues, certain
items included in the Company's Income Statements (see Financial Statements and
Notes) for the periods indicated:

SIX MONTHS ENDED JUNE 30, 2006 COMPARED TO SIX MONTHS ENDED JUNE 30, 2005

Revenues are derived from product sales and product support services. For the
six months ended June 30, 2006 revenues were $1,154,224, compared to $651,652 in
2005. The 77% increase in revenues results mainly from an increase in the number
of zNose(R) units shipped from 19 units in 2005 to 32 units in 2006 for the
six-month period. Also contributing to the increase in revenues was a slight
increase in sales from product support services.

Cost of Sales consist of product costs and expenses associated with product
support services. For the six-month period, cost of sales was $592,714 for 2006
as compared to $375,086 in 2005. The increase in cost of sales was due to a
greater volume of products shipped in the current year as compared to last year.
The improvement in cost of sales as a percent of revenues, from 58% of 2005
revenues to 51% of 2006 revenues, is attributed to production efficiencies and
production economies of scales resulting in overhead being spread over a greater
volume of production - all of which contributed to a lower manufacture cost per
unit.

                                        4


Gross profit was $561,510 for the six months ending June 30, 2006, compared to
$276,566 for the same period in 2005. The increase in gross profit was due to
greater sales volume, and an increase in high-margin support services revenues
over 2005. The improvement in 2006 gross profit from 42% in 2005 to 49% of
revenues is attributed to greater labor utilization, which improved labor
productivity and lowered the direct labor cost per manufactured unit.

Research and Development costs for the first six months of 2006 were $416,144
versus $331,285 for 2005. The increase of $84,859 in current year expenditures
over 2005 were mainly for greater personnel related expenses incurred for
enhancement of existing products and development of the Model 4300, the
company's newest zNose(R) product that was introduced to market in June 2006.

Selling, General and Administrative expenses for the six months ending June 30,
2006 were $1,436,961, compared to $1,103,030 for 2005. The $333,931 increase was
due to increased staffing required to support the growth of the company,
incurrence of necessary expenses associated with being a public company,
expansion of marketing activities including increased personnel staffing and
participation in a greater number of industry trade shows and conferences.

Interest expense for the first six months of 2006 was $1,416,279, as compared to
$34,271 in 2005. The increase in interest expense is primarily due to the
amortization of debt discount and stated interest associated with our $7,000,000
convertible debentures, which were issued in December 2005.

Other income-derivatives primarily consist of the decrease in the fair value of
derivative liabilities between the measurement dates. The increase in other
income during the six-month period ending June 30, 2006 when compared to prior
period is primarily attributable to a decrease in the quoted price of our common
stock. Please refer to Note 5 of our accompanying financial statements for
further explanation of the origin and nature of such income. We are unable to
determine whether we will record further decreases in the fair value of
derivative liabilities in the foreseeable future, which would be recorded as
other income-derivatives. Such decreases would be generally triggered by a
decrease in the fair value of our stock price, upon satisfaction of liquidated
damages pursuant to registration rights, or, possibly, upon satisfaction of our
convertible debentures.

Other expense-derivatives primarily consist of the recognition of derivative
liabilities we issued during the three-month period ended March 31, 2005. No
derivatives were issued during the three-month period ended June 30, 2005 nor
were any derivatives issued in 2006. Please refer to Notes 5 and 6 of our
accompanying financial statements for further explanation of the origin and
nature of such expenses.

LIQUIDITY AND CAPITAL RESOURCES

For the six-month period, net cash used by the Company for operating activities
were $1,454,193 and $1,364,616 for 2006 and 2005 respectively. Cash used in the
first six months of 2006 was comprised of the net loss for the period of
$1,024,755, less net non-cash items (including depreciation and amortization
expenses of $18,865, issuance of common shares for services of $21,000,
amortization of debt discount of $1,166,667, amortization of deferred financing
costs of $103,782, less decrease in fair value of derivative liability of
$1,683,119) of $372,805 minus the net change in operating assets and liabilities
of $56,633. Cash used in operations during the same six months of 2005 was
comprised of the net income for the period of $782,716, less net non-cash
expenses of $1,959,844 (including depreciation and amortization expenses of
$5,605, recognition of derivative liabilities of $2,298,501, less decrease in
fair value of derivative liability of $4,263,950), less the net change in
operating assets and liabilities of $187,488.

Investing activities provided cash of $599,413 in the first six months of 2006
and used $47,500 during the same period in 2005. Cash of $69,265 in 2006 and
$77,780 in 2005 were used to purchase of capital equipment. In 2005, $30,280 was
received from the sales of property and equipment. Whereas in 2006, $668,678 was
provided due to a reduction in the amount of collateral required for the
company's line of credit.

Financing activities for the first six months of 2006 consisted of $370,000 from
the line of credit the company has in place with its bank. The funds from the
credit line were used for operating expenses. In 2005, financing activities
provided cash of $3,501,708 primarily from the issuance of common stock in
February.

                                        5


On June 30, 2006 the Company's cash (including cash equivalents) was $3,735,141,
compared to $2,116,022 on June 30, 2005. The Company had a working capital on
June 30, 2006 of $436,679. The working capital includes $4,087,959 for
derivative liabilities - excluding this amount from current liabilities, the
Company's working capital would be $4,524,638. The Company's working deficit at
June 30, 2005 was $1,053,722 - excluding derivative liabilities of $1,753,400,
working capital would be $699,678.

The Company has a credit facility in place with East West Bank for $500,000. The
line of credit had borrowings of $370,000 against it at June 30, 2006. The funds
from the line of credit was used for operating expenses. The line of credit
expires on March 31, 2007.

Although the Company possesses a bank operating line of credit, there can be no
assurance that these proceeds will be adequate for our future 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.

The Company's primary capital needs are to fund its growth strategy, which
includes a sales and marketing staff to support the marketing, advertising and
selling of the zNose(R) family of chemical detection products, increasing
distribution channels both in the domestic and foreign markets, 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

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 do not foresee any material
inflationary trends for our product sources.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

ITEM 3. CONTROLS AND PROCEDURES

We have carried out an evaluation, under the supervision and with the
participation of our management, including our Chief Executive Officer and our
Vice President of Finance and Administration, on the effectiveness of the design
and operation of our disclosure controls and procedures as of June 30, 2006
pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, our Chief
Executive Officer and Vice President of Finance and Administration concluded
that our disclosure controls and procedures are effective to ensure that
information required to be disclosed by us in the reports that we file or submit
under the Exchange Act is recorded, processed, summarized and reported within
the time periods specified in the Securities and Exchange Commission's rules and
forms.

                                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. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We did not sell any unregistered equity securities or repurchase any of our
equity securities during the three months ended June 30, 2006.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

The terms of the convertible debentures and warrants that we issued in a private
placement on December 7, 2005 required that we register the shares of our common
stock underlying such debentures and warrants within 180 days of the date of
issuance of the debentures and warrants, as described more fully in the notes to
the consolidated financial statements contained in this Quarterly Report. The
failure to do so is an event of default under the debentures, giving the
debenture holders the right to accelerate the debentures and receive a premium
of approximately 30% of the outstanding amounts due under the debentures upon
acceleration. The failure to do so also reduces the exercise price of the
warrants by $0.03 per month until such registration statement is declared
effective. In addition, the failure to register such shares within 150 days of
the date of issuance of the debentures and warrants gives the holders the right
to receive liquidated damages in the amount of 2% per month of the purchase
price of the debentures and warrants, pursuant to a registration rights
agreement, and the failure to pay such liquidated damages relating to the
debentures is an event of default under the debentures. Although we have been
working diligently to obtain effectiveness of our registration statement and
continue to do so, we have thus far been unable to have such registration
statement declared effective by the Securities and Exchange Commission. As such,
the aforementioned penalties have been triggered.

At this time, the holders of the debentures and the warrants have the right to
declare an acceleration of debentures and to receive a premium thereon. If the
holders do so, we will owe them approximately $9.1 million, due and payable
immediately upon such declaration by the holders. Under the terms of the
warrants, the exercise prices of the warrants would have fallen from $0.4761 per
share to approximately $0.4061 per share. Pursuant to the registration rights
agreement, we would also owe the holders of the debentures and warrants
approximately $466,000, plus interest thereon at a rate of 18% per annum. As of
the present date, the holders of the debentures and warrants have not declared
an event of default under the debentures, nor have they made any demand for
payment of liquidated damages (although such demand is not required for the
latter). We are currently in settlement negotiations for the forbearance of the
exercise of the foregoing rights by the holders.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to the vote of security holders during the three
months ended June 30, 2006.

ITEM 5. OTHER INFORMATION

There is no other information to report.
