                          NOTES TO FINANCIAL STATEMENTS
                    FOR THE QUARTER ENDED SEPTEMBER 30, 2004
                                   (UNAUDITED)


1.    BASIS OF PRESENTATION

      The accompanying unaudited financial statements of Tech Laboratories, Inc.
      ("the Company") have been prepared in accordance with generally accepted
      accounting principles for interim financial information and with Item
      310(b) of Regulation SB. Accordingly, they do not include all of the
      information and footnotes required by generally accepted accounting
      principles for complete financial statements. In the opinion of
      management, all adjustments (consisting of normal recurring accruals)
      considered necessary for a fair presentation have been included. Operating
      results for the three and nine months ended, September 30, 2004 are not
      necessarily indicative of the results that may be expected for the year
      ended December 31, 2004. These unaudited financial statements should be
      read in conjunction with the audited financial statements and footnotes
      thereto included in the Company's Form 10-KSB/A for the year ended,
      December 31, 2003, as filed with the Securities and Exchange Commission.

      Certain prior year balances have been reclassified to conform to the
      current year presentation.

2.    LONG-TERM CONVERTIBLE DEBT

      On October 13, 2000, Tech Labs completed a $1.5 million financing of 6.5%
      convertible promissory notes due October 15, 2002. Interest is payable
      quarterly in cash or in shares of common stock at the option of the
      noteholders. Tech Labs disclosed all terms of this financing on Form 8-K
      filed on October 18, 2000.

      On January 11, 2002, Tech Labs entered into a conversion and redemption
      agreement concerning the long-term debt. An Event of Default, as defined
      in the 6.5% convertible notes, occurred on January 25, 2002, when Tech
      Labs was unable to make the first payment of $750,000 to the holders of
      the notes.

      On April 19, 2002, Tech Labs successfully negotiated a cure of the default
      referenced above. This cure required that Tech Labs' registration
      statement, filed with the Securities and Exchange Commission on April 5,
      2002, to have been declared effective on or before June 29, 2002, covered
      the shares underlying the 6.5% convertible notes. If the registration
      statement was declared effective by such date and Tech Labs made certain
      payments described in the Tech Labs' report on Form 8-K filed April 25,
      2002, the maturity date of the 6.5% convertible notes would have been
      extended from October 13, 2002 to December 30, 2002.

      On August 2, 2002, the Company announced that an Event of Default
      reoccurred on the 6.5% convertible notes. The Company was unable to have
      its registration statement declared effective by June 29, 2002, and was
      unable to reach a new agreement with the holders of the 6.5% convertible
      notes prior to the expiration of the waiver the Company had been granted
      by the holders of the notes. In October 2003 a cure was successfully
      negotiated and is further described in the Company's 8-K filed in October
      2003. In May 2004, Cornell Capital acquired convertible debt and signed a
      stand by equity financing agreement with Tech Labs, Inc. Financing
      availability is contingent on registration of the shares underlying this
      agreement. An SB-2 to register these shares is in process.

                      Management's Discussion and Analysis
                 of Financial Condition and Results of Operation



Item  2. Management's Discussion and Analysis of Financial Condition and Results
      of Operations.

      Quarter ending September 30, 2004, compared to Quarter ending September
      30, 2003

            Sales were $167,872 for the third quarter of 2004 as compared to
            $32,619 for the similar period of 2003. This increase was due to the
            sale of IDS Sensors to BAE Systems. The Company continues to seek
            long-term contracts with major computer companies. The company
            believes these contracts will provide future growth for its major
            Product DYNTRAX. Cost of sales of $92,179 for the third quarter of
            2004 has increased by $63,841 compared to the same period of 2003,
            primarily due to the BAE sale.

            Selling, general, and administrative expenses decreased by $46,984
            compared to the same period of 2003 due to decreases in selling
            expenses, and expenses associated with the company's attempts to
            raise long-term capital due to the successful completion of the
            stand by equity agreement.

            Net loss from operations of ($114,114) decreased $128,154 compared
            to a loss of ($242,268) for the prior period as a direct result of
            the BAE sale and declines in expenses incurred to explore long-term
            financing prospects.

      Nine Months Ended September 30, 2004, compared to Nine Months Ended
      September 30, 2003

            Sales were $233,138 for the nine months ended, September 30, 2004,
            as compared to $202,634 for the similar period of 2003. This
            increase was due to the sale of IDS Sensors to BAE Systems. The
            Company continues to seek long-term contracts with major computer
            companies. The company believes these contracts will provide future
            growth for its major Product DYNTRAX. Cost of sales of $131,043 for
            the nine months ended, September 30, 2004, decreased by $10,750
            compared to the same period of 2003.

            Selling, general, and administrative expenses increased by $186,849
            compared to the same period of 2003 due to increases in selling
            expenses, and expenses associated with the company's attempts to
            raise long-term capital due to the successful completion of the
            stand by equity agreement.

            Net loss from operations of ($786,426) increased $487,820 compared
            to a loss of ($298,606) for the prior period as a direct result of
            the increases in expenses incurred to explore long-term financing
            prospects, including the $340,000 commitment fee paid to Cornell
            Capital Partners, related to a standby equity distribution
            agreement.

                      Management's Discussion and Analysis
                 of Financial Condition and Results of Operation



LIQUIDITY AND CAPITAL RESOURCES

      The Company's operating activities utilized cash of $126,098 during the
      nine months ended, September 30, 2004, as compared to $22,550 during the
      nine months ended, September 30, 2003.

      As a result of operating losses and negative cash flow experienced during
      2001, 2002, and 2003, and continuing in 2004, Tech Labs has a tenuous
      liquidity position. If sales do not improve or alternative financing is
      not available in the near future, substantial doubt exists about Tech
      Labs' ability to continue as a going concern. The company has signed a
      stand-by equity distribution agreement with Cornell Capital Partners in
      May 2004, which could potentially provide approximately $8.5 million of
      future equity financing. The company is in the process of preparing an
      SB-2 registration statement registering the shares included in this
      agreement.

      During the first nine months of 2004, the Company is still suffering from
      the economic downturn.

Item  3. Controls and Procedures

      (a)   Evaluation of disclosure controls and procedures.

      Our Chief Executive Officer and Chief Financial Officer (collectively the
      "Certifying Officers") maintain a system of disclosure controls and
      procedures that is designed to provide reasonable assurance that
      information, which is required to be disclosed, is accumulated and
      communicated to management timely. Under the supervision and with the
      participation of management, the Certifying Officers evaluated the
      effectiveness of the design and operation of our disclosure controls and
      procedures (as defined in Rule [13a-14(c)/15d-14(c)] under the Exchange
      Act) within 90 days prior to the filing date of this report. Based upon
      that evaluation, the Certifying Officers concluded that our disclosure
      controls and procedures are effective in timely alerting them to material
      information relative to our company required to be disclosed in our
      periodic filings with the SEC.

      (b)   Changes in internal controls.

      Our Certifying Officer has indicated that there were no significant
      changes in our internal controls or other factors that could significantly
      affect such controls subsequent to the date of his evaluation, and there
      were no such control actions with regard to significant deficiencies and
      material weaknesses.

                           PART II - OTHER INFORMATION

Item  1. Legal Proceedings.

      On July 31, 2002, Tawfik Khalil and Amneh Khalil filed a lawsuit in the
      Superior Court of Passaic County, New Jersey, against Glen Venza, a
      Company part-time employee, Tech Labs, and certain other parties for
      property damages and personal injuries. The case arose from a car accident
      involving Mr. Venza and the plaintiffs, which occurred while Mr. Venza was
      performing certain duties for Tech Labs in a vehicle Mr. Venza borrowed
      from a third party. Tech Labs has only been named as a party to the
      personal injuries, and not for property damages, and believes it is
      covered for the accident by its insurance policy.

      A lawsuit was filed against a subsidiary of the Company, Tech Labs
      Community Networks, Inc. ("TLCN"), in the Superior Court of New Jersey,
      Passaic County, on February 20, 2003, claiming that the plaintiff
      delivered certain goods and services to TLCN and is owed $23,856, plus
      interest and attorney fees. We disagree that any goods or services were
      contracted to be provided to the plaintiff, and we believe we will prevail
      in this litigation.

      On July 30, 2003, a former director and a former employee filed a joint
      lawsuit in Superior Court of New Jersey, Passaic County, against us for
      consulting fees and expenses, respectively. In the same lawsuit, W.T.
      Sports filed a claim for a commission owed on sales due from a licensing
      agreement with us. The claims by the former director and former employee
      are for about $10,000 and we deny any liability under these claims and are
      defending the lawsuit. With regard to W.T. Sports, our agreement has an
      arbitration in case of dispute and therefore we are attempting to move
      this case to arbitration. We believe that we have a counterclaim, which is
      far in excess of the amount they claim we owe for the licensing fees. On
      November 11, 2004, an arbitration hearing took place. The decision by the
      arbitrator will be known by December 10, 2004.

      On June 30, 2004, the law firm of Stursberg & Veith, former counsel to
      Tech Laboratories, Inc., filed a lawsuit in the United States District
      Court for the Southern District of New York claiming that the plaintiff
      delivered certain good and valuable services to Tech laboratories and is
      owed $161,179.26 plus interest, costs, and disbursements for each cause of
      action, and other and further relief as the Court may deem necessary. The
      complaint alleges four causes of action including an unpaid account,
      stated breach of contract, quantim meruit, and unjust enrichment. We
      disagree with the amount of the unpaid balance owed to the plaintiff. We
      are in the process of filing a counterclaim for overcharging and certain
      wrongdoing by the plaitiff.
