              SCIENTIFIC INDUSTRIES, INC. AND SUBSIDIARY
    NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


     General:     The accompanying unaudited interim condensed
                  consolidated financial statements are prepared
                  pursuant to the Securities and Exchange
                  Commission's rules and regulations for reporting
                  on Form 10-QSB. Accordingly, certain information
                  and footnotes required by accounting principles
                  generally accepted in the United States for
                  complete financial statements are not included
                  herein. The Company believes all adjustments
                  necessary for a fair presentation of these interim
                  statements have been included and are of a normal
                  and recurring nature.  These interim statements
                  should be read in conjunction with the Company's
                  financial statements and notes thereto, included
                  in its Annual Report on Form 10-KSB, for the
                  fiscal year ended June 30, 2005.  The results for
                  the three and six months ended December 31, 2005,
                  are not necessarily an indication of the results
                  of the full fiscal year ending June 30, 2006.


 1.  Significant accounting policies:

     Principles of consolidation:

     The accompanying condensed consolidated financial statements
     include the accounts of the Company and Scientific Packaging
     Industries, Inc., a New York corporation and an inactive wholly
     owned subsidiary of the Company.  All intercompany items and
     transactions have been eliminated in consolidation.

 2.   Line of Business and Concentrations:

     The Company is engaged in manufacturing and marketing of
     equipment for research in university, hospital and industrial
     laboratories.  The Company believes that it has only one
     reportable segment.  Approximately 75% and 72% of net sales for
     the three month periods ended December 31, 2005 and 2004,
     respectively, were derived from the Company's main product, the
     Vortex-Genie(R) 2 mixer, excluding accessories, and approximately
     71% and 73% for the six month periods ended December 31, 2005
     and 2004, respectively.

     The Company's export sales (principally Europe and Asia) were
     approximately $434,000 and $435,000 for the three month periods

     and $748,000 for the six month periods ended December 31, 2005
     and 2004, respectively.

     46% and 49% of net sales for the three month periods ended
     December 31, 2005 and 2004, respectively, and 49% of total net
     sales for each of the six month periods ended December 31, 2005
     and 2004.

 4.  Earnings per common share:

     Basic earnings per common share are computed by dividing net
     income by the weighted-average number of shares outstanding.
     Diluted earnings per common share include the dilutive effect
     of stock options and a warrant, which was exercised at the end
     of September, 2005.


     Earnings per common share was computed as follows:

     All options outstanding as of December 31, 2005 and 2004 were
     included in the foregoing computations.  The warrant was
     included in the calculation for the periods prior to its
     exercise in September 2005.

 5.  Comprehensive Income:

     There was no significant difference between net income and
     comprehensive income for the three and six month periods ended
     December 31, 2005 and 2004.

 6.   Stock-Based Compensation Plans:

     The Company maintains an Incentive Stock Option Plan which it
     accounts for under the recognition and measurement principles
     of APB Opinion No. 25, "Accounting for Stock Issued to
     Employees," and related Interpretations.  No stock-based
     compensation costs are reflected in net income, as all options
     granted under those plans had an exercise price equal to the
     market value of the underlying common stock on the date of
     grant.  The following table illustrates the effect on net
     income and earnings per share if the Company had applied the
     fair value recognition provisions of FASB Statement No. 123,
     "Accounting for Stock-Based Compensation," to stock-based
     employee compensation:

 On December 16, 2004, the Financial Accounting Standards Board
 issued Statement No. 123 (revised 2004) that will require
 compensation costs related to share-based payment transactions to
 be recognized in the financial statements.  With limited
 exceptions, the amount of compensation cost will be measured based
 on the grant-date fair value of the equity or liability instruments
 issued.  In addition, liability awards will be measured each
 reporting period.  Compensation cost will be recognized over the
 period that an employee provides service in exchange for the award.
  Statement 123(R) replaces FASB Statement No. 123, Accounting for
 Stock-Based Compensation, and supercedes APB Opinion No. 25,
 accounting for Stock Issued to Employees.  SFAS 123(R) is effective
 at the beginning of the next fiscal year that begins after December
 15, 2005.  The Company is currently assessing the impact of
 adopting SFAS 123(R).

 Certain statements contained in this report are not based on
 historical facts, but are forward-looking statements that are based
 upon various assumptions about future conditions.  Actual events in
 the future could differ materially from those described in the
 forward-looking information.  Numerous unknown factors and future
 events could cause such differences, including but not limited to,
 product demand, market acceptance, impact of competition, the
 ability to reach final agreements, adverse economic conditions, and
 other factors affecting the Company's business that are beyond the
 Company's control.  Consequently, no forward-looking statement can

 Liquidity and Capital Resources

 Cash and cash equivalents decreased by $12,600 to $171,300 as of
 December 31, 2005 from $183,900 as of June 30, 2005.

 Net cash provided by operating activities was $182,800 for the six
 month period of the current fiscal year as compared to $100,100 in
 the comparative period for 2004.  The principal factors accounting
 for the difference was higher income and less of an increase in
 accounts receivable in 2005.  Cash used in investing activities was
 $197,400 for the current period as compared to $187,800 for the six
 months ended December 31, 2004 principally due to increased
 purchases of investment securities during the current year.

 On September 27, 2005, the Board of Directors of the Company
 declared a cash dividend of $.09 per share of Common Stock which
 was paid on January 13, 2006 to holders of record as of the close
 of business on October 27, 2005.

 The Company's working capital as of December 31, 2005 increased
 $121,100 to $2,369,900 from $2,248,800 at June 30, 2005.  The
 increase was mainly due to income from operations, partially offset
 by the accrual for the declared dividend.  The Company has
 available a secured bank line of credit of $200,000 with North Fork
 Bank with interest at prime, all of which was available as of
 December 31, 2005.  The Company has never borrowed under this line
 of credit.  Management believes that the Company will be able to
 meet its cash flow needs during the 12 months ended December 31,
 2005 from funds generated by operations and its available financial
 resources which include its cash and investment securities.

 Results of Operations

 Financial Overview

 Due mainly to higher sales and gross profit margins, the Company
 achieved net income of $89,700 and $186,600 for the three and six
 month periods ended December 31, 2005 - increases of $28,900 (48%)
 and $67,200 (56%) over the comparable periods last year.


 The Three Months Ended December 31, 2005 Compared with the Three
 Months Ended December 31, 2004.

 The Company's net sales for the three months ended December 31,
 2005 increased by $83,000 (9.8%) to $928,100 compared with $845,100
 for the three months ended December 31, 2004 primarily as a result
 of higher domestic sales of the Vortex-Genie(R) 2 mixer and a
 reduction in the prior year period's sales due to production
 interruptions caused by a supplier.

 The gross profit percentage for the three months ended December 31,
 2005 increased to 50.1% compared to 48.3% for the three months
 ended December 31, 2004, mainly as a result of lower production
 costs and increased selling prices of certain products.

 General and administrative expenses for the three months ended
 December 31, 2005 were higher by $44,800 (26.7%) for the current
 year's three month period - $212,700 compared to $167,900 for the
 three months ended December 31, 2004 - due primarily to higher
 costs incurred in pursuit of business opportunities.

 Selling expenses for the three months ended December 31, 2005
 decreased by $14,400 (17.7%) to $66,900 as compared with $81,300
 for the three months ended December 31, 2004 due to lower costs
 related to trade shows.

 Research and development expenses for the three months ended
 December 31, 2005 decreased by $10,100 (11.4%) to $78,400 as
 compared to $88,500 for the three months ended December 31, 2004 as
 a result of the substantial expenditures incurred in the prior
 period on the Multi-MicroPlate Genie(R) mixer.

 As a result of the foregoing, the Company's income before income
 taxes increased by $38,800 (49.2%) to $117,600 for the three months
 ended December 31, 2005 compared to $78,800 for the three months
 ended December 31, 2004.

 Income taxes were $27,900 for the three months ended December 31,
 2005 compared to $18,000 for the comparable period last year.

 The Company's net income increased by $28,900 (47.5%) to $89,700

              SCIENTIFIC INDUSTRIES, INC. AND SUBSIDIARY


 The Six Months Ended December 31, 2005 Compared with the Six Months
 Ended December 31, 2004.

 The increase of $121,200 (7.1%) in the Company's net sales for the six
 months ended December 31, 2005 to $1,818,100 as compared with
 $1,696,900 for the six months ended December 31, 2004 was
 principally due to increased  sales of new products in the first
 quarter and higher domestic sales of the Vortex-Genie 2 mixer in
 the second quarter of this year and the reduction in the prior
 year's second quarter sales due to production interruptions caused
 by a supplier.  The gross profit percentage for the six months
 ended December 31, 2005 improved to 50.7% compared to 47.5% for the
 prior year's period, mainly as a result of lower production costs
 and increased selling prices of certain products.

 General and administrative expenses for the six months ended
 December 31, 2005 increased by $41,300 (12.0%) to $386,700 as
 compared with $345,400 for the prior year's six-month period,
 mainly as a result of higher costs incurred in pursuit of business
 opportunities.

 Selling expenses decreased by $18,800 (12.6%) from $149,200 to
 $130,400 between the comparative six month periods, due mostly to
 lower costs related to trade shows.

 As a result of the foregoing, the Company's income before income
 taxes increased by $97,100(62.5%) to $252,500 for the six months
 ended December 31, 2005 compared to $155,400 for the six months
 ended December 31, 2004 and the income tax provision for the six
 months ended December 31, 2005 was $65,900 compared to $36,000 for
 the prior year's period.

 $67,200 (56.3%) to $186,600 compared to $119,400 for the same
 period last year.

 ITEM 3.  CONTROLS AND PROCEDURES

 As of the end of the period covered by this report, based on an
 evaluation of the Company's disclosure controls and procedures (as
 defined in Rules 13a-15(e) and 15d-15(e) under the Securities
 Exchange Act of 1934), the Chief Executive and Chief Financial
 Officer of the Company concluded that the Company's disclosure
 controls and procedures are effective to ensure that information
 required to be disclosed by the Company in its Exchange Act reports
 is recorded, processed, summarized and reported within the
 applicable time periods specified by the SEC's rules and forms.

 There was no change in the Company's internal controls over
 financial reporting that occurred during the most recent fiscal
 quarter that materially affected or is reasonably likely to
 materially affect the Company's internal controls over financial
 reporting.
