----------
(*) 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. We are in the process of amending our
registration statement on Form SB-2, for which an amendment was most recently
filed on October 20, 2006. Once that registration statement is declared
effective, we will be required to file annual, quarterly and periodic reports
with the Securities and Exchange Commission during the fiscal year in which such
registration statement is declared effective.

                       ELECTRONIC SENSOR TECHNOLOGY, INC.
                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)
                               September 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, for which an amendment including restated financial statements and
     related footnotes was filed on Form 10-KSB/A on September 26, 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
     September 30, 2006, and the results of operations and cash flows for the
     nine-month period ending September 30, 2006 have been included. The results
     of operations for the nine-month period ended September 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, included in the Annual Report filed on Form 10-KSB
     for the year then ended, for which an amendment including restated
     financial statements and related footnotes was filed on Form 10-KSB/A on
     September 26, 2006.

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. 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 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 September 30, 2006 and the accounts of
     Bluestone from February 1, 2005 to September 30, 2006.

3)   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.

                                       F-4


     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)   ALLOWANCE FOR DOUBTFUL ACCOUNTS

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

     d)   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. No amounts were due
          under this line of credit at September 30, 2006. The line of credit
          expires on March 31, 2007.

     e)   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.

     f)   SHIPPING AND HANDLING

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

     g)   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.

     h)   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


     i)   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.

     j)   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.

     k)   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.

     l)   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.

     m)   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 September 30,
          2006 no assets were impaired.

     n)   DERIVATIVE LIABILITIES

          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 September 30, 2006, the FASB still has not
          rescheduled EITF 05-04 for further discussion.

          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

                                       F-6


          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 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 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.

     o)   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 45,278,509 and 5,576,871 at September
          30, 2006 and 2005, respectively. The outstanding options, warrants and
          shares equivalent issuable pursuant to embedded conversion features
          and warrants at September 30, 2006 and 2005, respectively, are
          excluded from the loss per share computation for that period due to
          their antidilutive effect. The Company adjusted the numerator for any
          changes in income or loss that would result if the contract had been
          recorded as an equity instrument for accounting purposes during the
          period. However, the Company did not adjust the numerator for interest
          charges during the period on the convertible debentures because it
          would have been anti-dilutive.

                                       F-7

     p)   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 No. 123(R). 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. 123(R) 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.

     q)   RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

          In July 2005, the FASB issued FASB Staff Position ("FSP") 150-5,
          "Accounting Under SFAS 150 for Freestanding Warrants and Other Similar
          Instruments on Redeemable Shares". FSP 150-5 clarifies that warrants
          on shares that are redeemable or puttable immediately upon exercise
          and warrants on shares that are redeemable or puttable in the future
          qualify as liabilities under SFAS 150, regardless of the redemption
          feature or redemption price. The FSP is effective for the first
          reporting period beginning after September 30, 2005, with resulting
          changes to prior period statements reported as the cumulative effect
          of an accounting change in accordance with the transition provisions
          of SFAS 150. We adopted the provisions of FSP 150-5 on July 1, 2005,
          which did not have a material effect on our financial statements.

                                       F-8


          In July 2005, the FASB issued EITF 05-6, "Determining the Amortization
          period for Leasehold Improvements Purchased After Lease Inception or
          Acquired in a Business Combination", which addressed the amortization
          period for leasehold improvements made on operating leases acquired
          significantly after the beginning of the lease. The EITF is effective
          for leasehold improvements made in periods beginning after June 29,
          2005. We adopted the provisions of EITF 05-6 on July 1, 2005, which
          did not have a material impact to the Company's financial position,
          results of operations and cash flows.

          In September 2005, the FASB issued FASB Statement No. 157. This
          Statement defines fair value, establishes a framework for measuring
          fair value in generally accepted accounting principles (GAAP), and
          expands disclosures about fair value measurements. This Statement
          applies under other accounting pronouncements that require or permit
          fair value measurements, the Board having previously concluded in
          those accounting pronouncements that fair value is a relevant
          measurement attribute. Accordingly, this Statement does not require
          any new fair value measurements. However, for some entities, the
          application of this Statement will change current practices. This
          Statement is effective for financial statements for fiscal years
          beginning after November 15, 2007. Earlier application is permitted
          provided that the reporting entity has not yet issued financial
          statements for that fiscal year. Management believes this Statement
          will have no impact on the financial statements of the Company once
          adopted.

4)   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, which was subsequently reduced to $0.4000 as per a Forbearance
     and Amendment Agreement, dated September 7, 2006, with the holders of the
     convertible debentures (see Note 7), and can be redeemed at the lesser of
     $0.4000 or 90% of the average of the volume weighted average price for the
     20 consecutive trading days immediately prior to the conversion date. 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 stock payment is the lesser of $0.4544, which was subsequently reduced
     to $0.4000 as per a Forbearance and Amendment Agreement, dated September 7,
     2006, with the holders of the convertible debentures (see Note 7), or 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, which was subsequently reduced to
     $0.4300 per share as per a Forbearance and Amendment Agreement, dated
     September 7, 2006, with the holders of the warrants (see Note 7).
     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
               (which was subsequently extended to February 28, 2007 as per a
               Forbearance and Amendment Agreement, dated September 7, 2006,
               with the holders of the convertible debentures and warrants - see
               Note 7). The liquidated damages are payable in cash monthly or in
               unpaid, bear interest at 18% per annum. If unpaid by January 1,
               2008, they may be converted in shares of common stock at the same
               prevailing rate as the remaining principal amount of the
               convertible debentures;

                                       F-9


          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 (which was subsequently
               extended to February 28, 2007 as per a Forbearance and Amendment
               Agreement, dated September 7, 2006 with the holders of the
               convertible debentures and warrants - see Note 7). 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; and

          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
               (and was subsequently reduced to $0.4300 per share as per a
               Forbearance and Amendment Agreement, dated September 7, 2006,
               with the holders of the warrants - see Note 7), 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 (which was subsequently extended
               to February 28, 2007 as per a Forbearance and Amendment
               Agreement, dated September 7, 2006 with the holders of the
               warrants - see Note 7).

     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 $136,200 for the nine-month period ending September 30, 2006.

     See Note 5- 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.

     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.

5)   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.

                                      F-10


     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 September 30, 2006 is as follows:

                                         At issuance       At September 30, 2006
                                        -------------      ---------------------

     Freestanding warrants              $   6,017,350             $            0

     The Company used the following assumptions, using the Black Scholes Model
     to measure the identified derivatives as follows:

     Freestanding warrants

                                         At issuance      At September 30, 2006

     Market price:                      $        2.40            $         0.32
     Exercise price:                    $        1.00            $         1.00

     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

                                      F-11


     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 a
     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 timely filed). The default provisions are
     effective, at the holders' option, upon an event of default.

     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, which was subsequently
     reduced to $0.4000 as per a Forbearance and Amendment Agreement, dated
     September 7, 2006, with the holders of the convertible debentures (see Note
     7), 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.

     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 (which was subsequently extended to
     February 28, 2007 as per a Forbearance and Amendment Agreement, dated
     September 7, 2006 with the holders of the convertible debentures - see Note
     7). 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

                                      F-12


     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. The maximum
     liability associated with the liquidated damages amounts to 38% of the
     gross proceeds associated with the issuance of the convertible debentures,
     which amounts to $2,660,000.

     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 September 30, 2006 are as follows:

                                         At issuance       At September 30, 2006
                                        -------------      ---------------------
     Freestanding warrants              $  3,532,348            $      1,135,397
     Embedded conversion features          3,463,542                   3,208,333
     Liquidated damages                      192,500                           0
     Other outstanding warrants              143,268                      15,919

     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 revisits the weight of
     probabilities and the likelihood of scenarios at each measurement date of
     the derivative liabilities, which are the balance sheet dates.

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

     Embedded conversion features

                                         At issuance      At September 30, 2006
                                        -------------     ---------------------

     Market price:                      $      0.4880          $           0.32
     Conversion price:                  $      0.4544          $           0.29
     Term:                                    4 years                3.17 years
     Volatility:                                   39%                       39%
     Risk-free interest rate:                    4.39%                     4.69%

     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:

                                      F-13


                                         At issuance      At September 30, 2006
                                        -------------     ---------------------

     Market price:                      $       0.488          $           0.32
     Exercise price:                    $      0.4761          $           0.43
     Term:                                    5 years                4.17 years
     Volatility:                                   39%                       39%
     Risk-free interest rate:                    4.39%                     4.69%

     We adjusted the effective exercise price to reflect the contractual
     adjustment based on the Forbearance Agreement assuming that the warrants
     will most likely be registered before February 28, 2007.

     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 and $0 at the date of the
     grant of the registration rights and at September 30, 2006, respectively.

     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 was recorded as other expenses in December 2005.
     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 their issuance
     in 2005 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 and charged to other expenses (in 2005), and approximately
     $136,000 was allocated to deferred financing costs (in 2005).

     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 September 30,
     amounted to approximately $5.8 million and $1.4 million, and have been
     recorded as other income in 2005 and 2006, respectively.

6)   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 that took place on January 31, 2005, 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

                                      F-14


     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 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 September 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 and
     the remainder of his 500,000 options were cancelled. The 200,000 vested
     options were subsequently cancelled, without being exercised, in
     April 2006.

                                      F-15


     Accordingly, no expense associated with the outstanding options was
     recorded during the nine-month period ending September 30, 2006.

7)   FORBEARANCE AND AMENDMENT AGREEMENT

     On September 7, 2006, the Company entered into a Forbearance and Amendment
     Agreement with the holders of the convertible debentures and warrants that
     we issued in a private placement on December 7, 2005. The terms of the
     convertible debentures and warrants 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. The failure to do so
     is an event of default under the debentures, giving the 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 shares are registered. 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.

     Pursuant to the Forbearance and Amendment Agreement, the holders have
     agreed, among other things, to abstain from exercising the aforementioned
     rights and remedies arising out of the existing defaults under the
     debentures and warrants unless we are unable to register the shares
     underlying the convertible debentures and the warrants by February 28,
     2007. In exchange for such forbearance, the Company agreed to reduce the
     conversion price of the debentures issued on December 7, 2005 from
     $0.4544 per share to $0.4000 per share and to reduce the exercise price of
     the warrants issued to the holders of the convertible debentures on such
     date from $0.4761 per share to $0.4300 per share.

     The Forbearance and Amendment Agreement constitutes a temporary
     modification of terms of the convertible debentures and associated
     agreements. The temporary modification of terms impacts the probabilities
     and likely scenarios in our valuation of freestanding warrants, derivatives
     and liquidated damages associated with the convertible debentures and
     related financial instruments used at issuance and at each subsequent
     balance sheet date. Based on the terms of the Forbearance and Amendment
     Agreement and management's analysis of the status of its current
     registration statement, notwithstanding any unforeseen circumstances, the
     Company believes that it will be able to register all of the shares of its
     common stock underlying such debentures and warrants by February 28, 2007.
     Accordingly, the Forbearance and Amendment Agreement provides for revised
     probabilities and likely outcomes that the Company will use in its
     valuation of the embedded conversion features, the freestanding warrants
     and the liquidated damages associated with the issuance of the convertible
     debentures, as required by SFAS 133, paragraph 17. Such valuation is
     performed at each balance sheet date.

                                      F-16


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

--------------------------------------------------------------------------------

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 recognition. Cash payments received in advance of
product shipment or service revenue are recorded as deferred revenue.

                                        2


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 September 30, 2006 no assets were impaired.

We account for liquidated damages 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. We also account for our 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 is
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 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.

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:

NINE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 2005

Revenues are derived from product sales and product support services. For the
nine months ending September 30, 2006, revenues were $1,549,800, compared to
$1,417,700 for the same period in 2005. The 9% increase in revenues results from
an increase in the number of zNose(R) units shipped from 37 during the nine
month period ending September 30, 2005 to 42 units for the same period in 2006.
Product support revenues for the nine month ending September 30, 2006 were
approximately the same as that in 2005 over the same period.

Cost of Sales consist of product costs and expenses associated with product
support services. For the nine months ending September 30, 2006, cost of sales
was $731,500, compared to $592,700 for the same period 2005. Cost of sales
increased from 42% of revenues in 2005 to 47% of revenues in 2006 due to quality
issues with some materials that required additional labor to investigate,
identify, locate and correct. There were also additional labor costs incurred to
produce the Model 4300, which is in the initial stages of production. The Model
4300 was introduced to market in June 2006.

Gross profit was $818,300 for the nine months ending September 30, 2006,
compared to $825,000 for the same period in 2005. Gross profit as a percentage
of revenues decreased from 58% in 2005 to 53% for the reasons noted in the Cost
of Sales discussion above. Margins, however, are expected to recover as the
vendor based quality issues have been resolved and through manufacturing and
learning curve efficiencies which are expected to result as production of the
Model 4300 increases.

Research and Development costs for the nine months ending September 30, 2006
were $616,600 versus $618,500 for the same period in 2005. Increased engineering
staffing resulted in personnel related expenses being approximately $55,000
greater than in 2005. The increased in staffing reduced the need to out-source
certain engineering tasks which resulted in a reduction of approximately $73,000
for external engineering support services. Additionally, there was also a slight
decrease in engineering overhead expenses of approximately $18,000.

Selling, General and Administrative expenses for the nine months ending
September 30, 2006 were $2,060,900, compared to $1,825,000 for the same period
in 2005. The $235,900 increase was due to the hiring of new employees
necessitated by the growth of the business, expanded marketing activities,
offset by a reduction in legal and related expenses incurred in connection with
the company's reverse merger and IPO in 2005.

Interest expense for the nine months ending September 30, 2006 was $2,105,500,
as compared to $54,700 for the same period in 2005. The increase in interest
expense is primarily due to the amortization of debt discount and stated
interest associated with our 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 for the nine month period ending September 30, 2006, as compared to the
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 have been issued in 2006. Please refer to Note 5 of our accompanying
financial statements for further explanation of the origin and nature of such
expenses. We believe that we will incur additional expenses associated with the
fair value at issuance of financial instruments which will be recorded pursuant
to derivative accounting. However, we are unable to determine the expected
amount we would

                                        4


recognize pursuant to such issuances since their fair value is computed based on
a number of assumptions, including, among others, the fair value of our stock
price, expected term and exercise price of the financial instrument and expected
volatility of our stock price, which will only be known at the date of issuance.

LIQUIDITY AND CAPITAL RESOURCES

For the nine months ending September 30, 2006, net cash used by the Company for
operating activities were $2,355,525 and $2,247,767 for 2006 and 2005
respectively. Cash used for the nine months ending September 30, 2006 was
comprised of the net loss for the period of $2,552,763, plus net non-cash items
(including depreciation and amortization expenses of $29,836, issuance of common
shares for services of $21,000, amortization of debt discount of $1,750,000,
amortization of deferred financing costs of $136,160, less decrease in fair
value of derivative liability of $1,411,430) of $525,566 minus the net change in
operating assets and liabilities of $328,328. Cash used in operations during the
same nine months of 2005 was comprised of the net income for the period of
$1,908,891, less net non-cash expenses (including depreciation and amortization
expenses of $11,430, recognition of derivative liabilities of $2,205,642, less
decrease in fair value of derivative liability of $5,778,250) of $3,561,178, and
less the net change in operating assets and liabilities of $595,480.

Investing activities provided cash of $544,621 in the first nine months of 2006
and used $991,325 during the same period in 2005. Cash of $124,057 in 2006, and
$108,954 in 2005 were used to purchase capital equipment. In 2005, $30,280 was
received from the sales of property and equipment, and $912,651 was used for
collateral on the company's credit line. Whereas in 2006, $668,678 was provided
through a reduction in the amount of collateral required for the company's
reduced line of credit.

There were no financing activities for the first nine months of 2006. In 2005,
financing activities provided $3,432,708 from the issuance of common stock for
$3,811,708, less decrease in the line of credit for $269,000 and repayment of
partners' loans for $110,000.

On September 30, 2006 the Company's cash (including cash equivalents) was
$2,409,017, compared to $220,047 on September 30, 2005. The Company had a
working deficit on September 30, 2006 of $519,436. The working deficit includes
$4,359,649 for derivative liabilities - excluding this amount from current
liabilities; the Company's working capital would be $3,840,213. The Company's
working deficit at September 30, 2005 was $212,423 - excluding derivative
liabilities; working capital would be $26,677.

The Company has a credit facility in place with East West Bank for $500,000. No
amounts were due under this line of credit at September 30, 2006. 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 long-term 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 creating a sales and marketing staff for the marketing, advertising and
selling of the zNose(R) family of chemical detection products, increasing
distribution channels both in U.S. and foreign countries, introducing new
products, improving existing product lines and development of a strong corporate
infrastructure.

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.
