                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.  BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of Eco Soil Systems, Inc. (the "Company"), all
adjustments, consisting only of normal recurring adjustments, necessary for the
fair statement of the results for the three-month periods ended June 30, 2000
and 1999 have been made. The results of operations for the three-month and
six-month periods ended June 30, 2000 are not necessarily indicative of the
results to be expected for the full fiscal year. For further information, refer
to the audited financial statements and notes thereto included in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 1999.

2.  NET LOSS PER SHARE

     In accordance with Financial Accounting Standards Board Statement No. 128,
"Earnings per share" ("SFAS 128"), basic earnings (loss) per share is calculated
by dividing net (loss) by the weighted average number of common shares
outstanding for the period. Diluted earnings per share reflects the potential
dilution of securities that could share in the earnings of the Company such as
common stock which may be issuable upon exercise of outstanding stock options
and warrants. These shares are excluded when their effects are antidilutive.

3.  DISCONTINUED OPERATIONS

     On July 28, 2000, the Company completed the sale of substantially all of
the assets of its Turf Partners subsidiary (the "Asset Sale") to the J.R.
Simplot Company ("Simplot"). At the closing of the Asset Sale, Simplot made a
cash payment of $23 million in cash and assumed Turf Partners' exiting long-term
debt and vendor payables totaling $38.5 million. Simplot also assumed Turf
Partners' outstanding contracts and leases. The Asset Sale was consummated
pursuant to an Amended and Restated Asset Purchase Agreement dated April 5,
2000, as amended by a First Amendment to Amended and Restated Asset Purchase
Agreement dated June 9, 2000.

above. Interest expense allocated to the discontinued operations totaled
$730,000 and $330,000 for the three months ended June 30, 2000 and 1999,
respectively, and $1.5 million and $621,000 for the six months ended June 30,
2000 and 1999, respectively. Also, selling, general and administrative expenses
that were recorded by the parent company but were specifically an expense of the
discontinued operations have been allocated to the discontinued operations as
shown above. The amount of selling, general and administrative expenses
allocated by the parent company to the discontinued operations totaled $728,000
and $126,000 for the three months ended June 30, 2000 and 1999, respectively,
and $1.3 million and $622,000 for the six months ended June 30, 2000 and 1999,
respectively.

    The historical consolidated balance sheets reflect the assets and
liabilities of discontinued operations as current or non-current assets based on
the original classification of the accounts, except that current liabilities are
netted against current assets and non-current liabilities are netted against
non-current assets.

    The following pro forma financial statements reflect the Asset Sale as if
the sale to Simplot was completed on June 30, 2000. Also, this information
should be read in conjunction with the financial statements and notes thereto
included in Item 1 of this report for the quarter ended June 30, 2000.

    The following pro forma adjustments have been recorded to the historical
financial statements: (i) an adjustment of $749,000 to reflect shipments to Turf
Partners from the parent company as if they were independent companies as of
June 30, 2000, (ii) the recognition of a gain on the sale of the discontinued
operations of $17.8 million, (iii) the application of $23 million of proceeds
from the Asset Sale as follows: (a) retired $14 million of the $15 million
Senior Subordinated Notes, (b) repaid the Simplot Term Loan of $3 million
received in July 2000, and (c) paid $1.1 million in closing fees, and (iv) a
$3.9 million write-off of debt issuance costs related to the Senior Subordinated
Notes.

4.  RESTRUCTURING CHARGES

    During the second quarter, the Company incurred a restructuring charge of
$1.1 million as a result of the closure of five operating locations of the
Agricultural Supply subsidiary located in the United States and Mexico.

    A total of 25 employees were terminated from these locations, with almost
all of them having left the Company as of June 30, 2000. The remaining accrued
liabilities associated with these operations are expected to be recognized
during the second half of fiscal 2000.

      Details of the restructuring charge (in thousands) are as follows:
