2.       CLOSING. Subject to the terms and conditions of this Agreement, the
closing of the purchase and sale of the Brehm Common Stock (the "Closing")

mutually agreed upon by the parties hereto in writing. (Such time and date is
sometimes hereinafter referred to as the "Closing Date" or "Closing".)

3.       PROCEDURE AT THE CLOSING. At the Closing, the parties hereto agree to
take the following steps in the order listed:

A.       Seller shall deliver to the Buyer the Brehm Common Stock, and such
stock powers and other instruments to transfer to the Buyer good and marketable
title to the Brehm Common Stock, free and clear of all liens, claims and
encumbrances.

B.       In exchange for the Brehm Common Stock, Buyer shall transfer to Seller:

                  (1) Shares of registered EarthCare Common Stock equal in

D.       The parties shall also exchange an executed Lock-up Agreement as well
as a consulting agreement, in the form attached hereto as Exhibit 3-D.

E.       The purchase price shall be adjusted (the "Adjustment") as follows:

1.       If the Company's current assets as of the Closing Date exceed the
Company's current liabilities as of such date, then such excess shall be paid
to Seller as an addition to the purchase price.
2.       If the Company's current liabilities as of the Closing Date exceed the
Company's current assets as of such date, then Seller shall reimburse to Buyer
an amount equal to such deficiency.

                                       2
<PAGE>   3

after the Closing Date ("the Adjustment Date"). Current assets and current
liabilities shall be determined in accordance with generally accepted
accounting principles except that accounts receivable, including unbilled
services rendered to the date of Closing and billed thereafter (the "Accounts
Receivable"), will be considered current assets only if collected prior to the
Adjustment Date or are otherwise accepted in writing by Buyer. Buyer agrees
that all amounts collected shall be applied first to Accounts Receivable
generated prior to the Closing and that Buyer shall cause the Company to
collect the Accounts Receivable in the same manner as that employed by Buyer
and its affiliates in the collection of accounts receivable in general.

4.       The Adjustment shall be made hereunder as follows:

         a.       If there is an excess of current assets over current
liabilities, the excess, to the extent of cash collected through the Adjustment
Date, shall be paid to Seller on the Adjustment Date. To the extent such excess
is in the form of yet uncollected Accounts Receivable, Buyer shall cause the
Company to continue to collect such outstanding Accounts Receivables after the
Adjustment Date and Buyer shall pay to Seller, monthly, Accounts Receivables
thereafter collected. Payment on account of the Accounts Receivables shall be
made by the 10th day of each month for collections received during the
preceding month and shall be accompanied by a statement of Accounts Receivables
collected.
         b.       If the current liabilities exceed current assets then, at
Seller's election, (a) Seller shall pay to Buyer the amount of such deficiency
or (b) the number of the Holdback Shares (as defined in Paragraph 3-B(1))
having a Value (calculated at the then current market) equal to the deficiency
shall be released to Buyer and, in either such event, Buyer shall pay to Seller
on a monthly basis as described above, an amount equal to the Accounts
Receivable thereafter collected by the Company.

ordinary course of business or reserved against in the Buyer Financial
Statements or reflected in the notes thereto or (ii) which were incurred after
December 31, 1998, and were incurred in the ordinary course of business and

                           (1) Long Term Liabilities Adjustment. In the event
           the liabilities of the Company as of the Closing Date for the payoff
           amounts under the leases set forth on Schedule 2.B(1) and under the
           promissory notes identified on Schedule 2.B(1) (collectively the
           "Long Term Liabilities") are not equal to $513,000, then the cash
           portion of the Merger Consideration shall be modified by an amount
           equal to $513,000 minus the amount of the Long Term Liabilities.

                           (2) Accounts Receivable Adjustment. Ninety (90) days
           after the Closing Date the stock portion of the Merger Consideration

           with the following:

                           (a) After Closing, Subsidiary will use reasonable
                      efforts to collect accounts receivable and retainage in
                      accordance with prudent business practices and in a manner
                      which will not result in the discount of other accounts
                      receivable or retainage owed by the same account debtor or
                      of the terms on which goods or services are provided to
                      the same account debtor in the future.

<PAGE>   6

                           (b) Payments by an account debtor will be applied to
                      the oldest invoices and retainage first if the account
                      debtor does not designate application of payments to
                      specific invoices.

                           (c) Accounts receivable which are not collected
                      within 90 days after they arose will be applied to the
                      allowance for doubtful accounts reflected on the most
                      recent Balance Sheet, and no reduction to the Merger
                      Consideration shall be made under this Section 2.B(2)
                      until the allowance for doubtful accounts reflected on the
                      Balance Sheet has been reduced to zero.

                           (d) To the extent an account receivable is not
                      collected within 90 days after the Closing Date and the
                      Merger Consideration is reduced under this Section 2.B(2),
                      Subsidiary will, upon the request of the Shareholders,
                      assign the account receivable to the Shareholders. Any
                      such assignment shall be made without recourse to
                      Subsidiary, and the Shareholders shall indemnify
                      Subsidiary against any claims which may be asserted by the
                      account debtor which arose prior to the Closing Date. In
                      the event such assignment is of only a portion of an
                      account receivable, the Shareholders and Subsidiary shall
                      cooperate in the collection thereof.

                           (e) The number of shares of EarthCare Stock used to
                      satisfy any adjustment to the Merger Consideration due to
                      the failure to collect accounts receivable pursuant to
                      this Section 2.B(2) shall be based upon the closing sale
                      price of a share of EarthCare Stock on the NASDAQ

                                      -6-
