          account potential tariff rebates that are currently being applied for.
          The tariffs were  charged on some raw  materials  used to  manufacture
          products that were shipped in both 2019 and 2020.

     o    Basic  weighted  average  shares used in computing  earnings per share

     o    Non-GAAP  operating cash flow:  For the 12 months ending  December 31,
          2020,   net   income   reflects   $1,007,684   of   non-cash   charges
          (depreciation,  stock  option  expenses),  as well as gain  (loss)  on
          disposition of equipment,  gain(loss) on investment, interest expense,
          interest income, write down of inventory, Income tax expense/recovery,

          these items are removed,  the  financials  show operating cash flow of
          $4,514,182 or $0.37 per share.  This compares with operating cash flow

Notes: certain items not related to "operations" of the Company's net income are
listed below.

a)    Non-GAAP - Flexible Solutions International purchased 65% of ENP in 4th
      quarter, 2018 (October 2018). Therefore Operating Cash Flow is adjusted by
      the pre-tax Net income or loss of the non-controlling interest in ENP. An
      adjustment to 2019 Operating cash flow has been made to account for the
      use of a pre-tax amount versus an after tax amount which was originally
      used in that year.

                                       2


b)    Non-GAAP  -  amounts   exclude   certain   cash  and   non-cash   items:
      depreciation and stock compensation  expense (2020 = $1,007,684,  2019 =
      $866,708),   interest  expense  (2020  =  $260,657,  2019  =  $428,371),
      interest  income (2020 = $53,101,  2019 = $80,731),  gain on  investment
      (2020 = $877,358,  2019 = $323,824),  gain on sale of equipment  (2020 =
      9,490,  2019 =  $2,312),  Gain  on  acquisition  of ENP  Realty  (2020 =
      $133,341,  2019 = N/A),  Deferred income tax recovery  (expense) (2020 =
      (409,553),  2019 =  $602,421),  Income  tax (2020 =  $1,197,888,  2019 =
      $619,857),  and  pre-tax  Net  income  attributable  to  non-controlling
      interests  (2020  =  $871,844,  2019 =  $583,793).  *See  the  financial
      statements for all adjustments.

c)    The revenue and gain from the 50% investment in the private  Florida LLC
      announced  in January  2019 is not  treated  as  revenue or profit  from
      operations by Flexible  Solutions  given the Company only  purchased 50%
      of the LLC.  The profit is treated as  investment  income and  therefore
      occurs  below  Operating  income in the  Statement of  Operations.  As a
      result,  the gains from all  investments  (2020 =  $877,358,  and 2019 =
      $323,824),  including  those from the Florida  LLC, are removed from the
      calculation to arrive at Operating Cash Flow.

d)    Non-GAAP - amounts represent depreciation and stock compensation expense.
