                             PENTAIR, INC.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

       1.  The accompanying unaudited condensed consolidated 
           financial statements have been prepared in accordance with 
           instructions for Form 10-Q and, accordingly, do not include
           all information and footnotes required by generally accepted 
           accounting principles for complete financial statements.
           In the opinion of management, all adjustments, consisting
           only of normal recurring accruals, considered necessary 
           for a fair presentation have been included.

           These statements should be read in conjunction with the 
           financial statements and footnotes included in the Company's 
           Annual Report on Form 10-K for the year ended December 31, 
           1996, previously filed with the Commission.

       2.  The results of operations for the three months ended 
           March 31, 1997 are not necessarily indicative of the 
           operating results to be expected for the full year.

      3.   Income tax provisions for interim periods are based on 
           the current best estimate of the effective federal, 
           state and foreign income tax rates.

      4.   Earnings per common share are based on the weighted 
           average number of common and common equivalent shares 
           outstanding during each period. The tax benefits
           applicable to preferred dividends paid to ESOPs are: 
           for allocated shares credited to income tax expense and for 
           unallocated shares, credited to retained earnings 
           and are not considered earnings applicable to common stock.

           Fully diluted computations assume full conversion of 
           each series of preferred stock into common stock, 
           the elimination of preferred dividend requirements, 
           and the recognition of the tax benefit on deductible ESOP 
           dividends applicable to allocated shares payable
           based on the converted common dividend rate. Conversion
           was assumed during the portion of each period that the
           securities were outstanding.


      5.   The long-term debt is summarized as follows ($ millions):


                                    March 31,   December 31,
                                    1997        1996

                                           
     Revolving credit facilities    $189         $168 
     Private placement debt          125          115 
     Other                            32           30 
     TOTAL                           346          313 
     Current maturities               (45)        (33)
     Total long-term debt            $301        $280 


          Debt agreements contain various restrictive covenants, including
          a limitation on the payment of dividends and certain other 
          restricted payments.  Under the most restrictive covenants,  
          $118 million of the March 31, 1997 retained earnings were
          unrestricted for such purposes.

      6.   Statement of Cash Flows

           The following is supplemental information relating to
           the Statement of Cash Flows ($000's):


                               Three Months Ended March 31
                                  1997        1996
                                        
         Interest paid
         (net of capitalized
          interest in 1997)      $2,538       $6,187
         Income tax payments     10,981        3,310


      7.   Recent Accounting Standards

           In February 1997, the Financial Accounting Standards Board
           issued Statement of Financial Accounting Standards No. 128, 
           "Earnings Per Share," which is effective for financial 
           statements issued for the periods ending after December 15, 
           1997, including interim periods; earlier application is not 
           permitted.  The Company has determined that adoption of the 
           standard will not have a material effect on the Company's 
           financial position or results of operations.

      RESULTS OF OPERATIONS

      Consolidated Results.
      Consolidated net sales increased to $411.1 million in 1997, 
      representing a 12.2% increase over 1996.  The double digit growth 
      rate is attributed to strength in power tools, North American 
      enclosures and pumps, as well as acquisitions (Flex, Century, 
      SIATA, and Transrack).  These more than offset continuing 
      economic weakness in Europe and adverse currency effects of the 
      strong U.S. dollar.

      Operating income increased to $37.5 million in 1997, up 14.9% 
      over 1996, and operating income as a percent of sales improved 
      from 8.9% to 9.1%.  Gross profit margins declined .7% in 1997 
      to 30.6% versus 31.3% in 1996.  This is primarily due to 
      product mix.  Selling, general and administrative expense (SG&A)
      as a percent of sales was 21.5% in 1997 as compared to 22.4% in 1996,
      thus offsetting the change in the gross profit margin. 

      Specialty Products Segment.
      Specialty Products sales increased $22.1 million or 14.4%, 
      propelled by new product introductions, expanded distribution 
      in home center and hardware channels, and acquisitions.  The 
      Tool businesses grew from acquisitions (Flex by Porter-Cable)
      and continued expansion new channels, including Sears, and new 
      product introductions.  In the Water products businesses,
      slow economic conditions in the European markets of Fleck Controls
      were balanced by gains at the Myers pump business. Myers' excellent
      operating performance was supplemented by demand for pumps resulting 
      from flood conditions in the U.S.  The SIATA acquisition (by Fleck 
      Controls) contributed to sales and income in 1997.

      Operating income as a percent of sales decreased to 11.8% in 1997 
      from 12.3% in 1996 due to product mix and the continued economic 
      softness in Europe that affected both Flex and Fleck Controls.
 
      General Industrial Equipment Segment.
      General Industrial Equipment sales increased $22.8 million or 10.7%.
      North American sales growth was strong enough to overcome weaker 
      European sales (especially as measured in a stronger U.S. Dollar)
      in the enclosure and lubrication systems businesses in the first 
      quarter of 1997.  Sales at Federal increased as a result of
      introduction of new products and a reduction in ammunition industry
      discounting. The acquisition of Century Manufacturing contributed 
      sales and income to the vehicle service equipment businesses in 1997.

      Operating income as a percent of sales increased to 9.5% in 1997 
      from 9.0% in 1996 primarily as a result of higher profitability
      at Federal.


      FINANCIAL CONDITION
      Cash flow from operating activities was negative $4.7 million in 
      1997 compared to negative $15.9 million in 1996.  The improvement in 
      reducing cash used by operating activities in 1997 as compared to 1996 
      was a result of continued focus on managing working capital, principally
      by controlling the increase in inventories in relation to sales growth.
      Accounts receivable levels increased due to dating programs and the
      addition of acquisition sales.

      Capital expenditures were $21.5 million in 1997 as compared to 
      $9.4 million in 1996. The increase is primarily due to peak
      construction efforts at Hoffman's new Mt. Sterling facility. The 
      Company had a negative free cash flow of $26.2 million in 1997 
      compared to negative $25.3 million in 1996. Free cash flow,
      a measure of the internal financing of operational cash needs, 
      is defined as cash from operations less capital expenditures. 
      One of Pentair's primary financial goals is to maximize free
      cash flow within the framework of supporting the operations of all 
      of its businesses.

      Borrowings in the first quarter of 1997 financed some operating
      needs and acquisition payments, along with capital expenditures.
      The percentage of long-term debt to total capital was 34% at
      March 31, 1997 compared to 33% at December 31, 1996.


      OUTLOOK

      In general, the Company is well-positioned to continue its
      aggressive growth. Recent acquisitions are expected to continue to 
      contribute to sales and earnings growth.  The strong emphasis on 
      product development and aggressive efforts to expand distribution
      channels that helped during 1996 are expected to generate growth
      in market share, sales and profits.  In all subsidiaries, sales are
      expected to grow as a result of new products and enhanced customer 
      service.  Pentair also continues to search for strategic or synergistic
      industrial acquisitions to complement its existing businesses.

      The diversification of the industrial businesses in Pentair's
      various markets has helped the company to maintain consistent growth
      over the past few years.  Also diversity in geography has helped the
      company to weather the various economic patterns. 

      Capital outlays in 1997 are expected to be in the  $70 million range.
      Projects include completion of the manufacturing plant for Hoffman
      Engineering in Mount Sterling, Kentucky, reconfiguration and expansion 
      of manufacturing facilities and new product development.  The Company
      believes that these capital expenditures are expected to be
      financed out of its operating cash flows.

      Looking ahead in 1997, the Company expects that cash from operating
      activities should continue to provide the funds for capital investments,
      dividends and small acquisitions. The Company has the capacity to 
      finance larger acquisitions while maintaining reasonable financial ratios.

      The Company's future results of operations and the other forward 
      looking statements contained in the Outlook, in particular statements 
      about acquisitions, capital spending and sales growth, involve a number
      of risks and uncertainties.  In addition to the factors discussed
      specifically above, among the other factors that could cause actual 
      results to differ materially include the following: business conditions 
      and the general economy; competitive factors, such as market acceptance 
      of new products, pricing, and the impact of competitive products; risk 
      of nonpayment of accounts receivable; manufacturing capacity; risks 
      associated with foreign operations; risks of inventory obsolescence 
      due to shifts in market demand; timing of product introductions;
      and litigation regarding environmental issues.  The actual results the 
      Company achieves may differ materially from those anticipated as a 
      result of these risks and uncertainties.  Readers are encouraged to 
      carefully review and consider disclosures made by the Company in this
      report and in the Company's Annual Report and other reports filed
      from time to time with the Securities and Exchange Commission. 

      Future revenues, costs, margins, product mix and profits are all
      influenced by a number of factors, as discussed above, however 
      Pentair believes that it has the products, facilities, personnel,
      competitive advantage, and financial resources for continued
      business success.
