     THIS SEPARATION AND NON-COMPETITION AGREEMENT is made as of this 25th day
of February, 2000, by and between ENVIRONMENTAL ELEMENTS CORPORATION, a Delaware
corporation with principal offices at 3700 Koppers Street, Baltimore, Maryland
21227 (hereinafter referred to as "Company") and E. H. VERDERY (hereinafter
referred to as "Mr. Verdery").

                                  Background

1. Mr. Verdery has resigned his employment with the Company effective February
   25, 2000, and has further resigned from the office of Chairman of the Board
   of Directors, President and Director of the Company effective February 25,
   2000 and from all other offices of the Company and of its subsidiaries
   effective February 25, 2000.

2. The Company and Mr. Verdery are desirous of reaching an agreement concerning
   the terms of the separation of Mr. Verdery from the Company.

     NOW, THEREFORE, in consideration of the premises and mutual covenants,
understandings, and agreements contained in this Agreement, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by both parties, and in lieu of any other severance arrangements,
or company policy or precedent, it is hereby agreed by and between the parties
as follows:

1. Mr. Verdery's last day as an employee of EEC will be February 25, 2000.

2. Beginning February 26, 2000 Mr. Verdery will receive a severance package
   consisting of one of the following two alternatives, Option A or Option B.
   Mr. Verdery will notify the Company not later than April 25, 2000 if he
   elects to receive the lump sum package described as Option B. Mr. Verdery's
   failure to provide notice, which is received by the Company on or before
   April 25, 2000 that he wishes his severance package to be Option B, shall
   constitute notice to the Company of Mr. Verdery's election of Option A.

     The severance package options are as follows:

     Option A - Beginning February 26, 2000 Mr. Verdery will receive severance
     --------
     pay based on his annual salary of $275,000.00, payable in bi-weekly
     installments through March 31, 2001, a total of $301,369.70. During this
     period, he will continue to have available his medical, drug, dental,
     vision, group life insurance, accidental death and dismemberment, and long
     term disability benefits, all at levels and with elections in effect on
     February 25, 2000. For a period beginning on the date hereof and ending on
     the earlier of (i) the date upon which Mr. Verdery accepts full time
     employment, or (ii) March 31, 2001, the Company will continue to lease the
     vehicle currently leased for the benefit of Mr. Verdery, and will continue
     to include that vehicle in its vehicle insurance program. Mr. Verdery will
     pay all fuel and maintenance costs of the vehicle during this period, and
     will return the vehicle to the Company at the end of this period in as good
     condition as at the date hereof, normal wear and tear expected.

     Option B - Beginning - Beginning February 26, 2000, Mr. Verdery will

     the period beginning February 26, 2000 and ending March 31, 2001, or a
     total of $301,369.72. From the date hereof until the payment of this lump
     sum, if elected, the Company will pay Mr. Verdery bi-weekly and will
     continue his benefits as if he had selected Option A. In computing the lump
     sum due, if elected, the Company shall reduce the total amount due,
     $301,369.72, by the amount paid out in bi-weekly installments from the date
     hereof until the date the remaining lump sum payment is made. From the date
     the lump sum payment is made forward, Mr. Verdery shall not be entitled to
     the benefits described in Option A, pension credits under Section 4 herein,
     and he shall return promptly the leased vehicle whose use he is permitted
     under Option A in as good condition as the date hereof, normal wear and
     tear expected. The lump sum payment, if any, shall be due fifteen days
     following the Company's receipt of Mr. Verdery's notice of his election of
     Option B, pursuant to the terms above and returns the leased vehicle to the
     Company. Mr. Verdery's opportunity to elect this Option B expires at close
     of business on April 25, 2000.

3.   In accordance with the EEC Stock Option Plan, Mr. Verdery's right to
     exercise his options shall terminate at the expiration of three months
     after your termination date of February 25,

     employment for your entire severance pay period. You are entitled to a
     future pension benefit from the EEC Retirement Plan at age 65.

     acquire any interest in, become employed by, or provide consulting services
     to, or otherwise participate in, either directly or indirectly, other than

     accepting employment by corporations (for example ABB) which have, among
     their various businesses or business units, businesses or business units
     which are in competition with the Company, so long as Mr. Verdery is not
     directly responsible for such businesses or business units during the
     period ending March 31, 2001. In any event, however, the restrictions
     contained in paragraph (ii) below will remain in full force and effect.
     (ii) Mr. Verdery will not disclose to any person or other entity any trade
     secrets, customer or supplier names, computer programs, cost and pricing
     data, product development efforts, now-how and show-how, proposal and
