Gentlemen:

         Reference is made to the amended and restated stock purchase agreement,
dated as of August 30, 2000 (the "Purchase Agreement"), among Commodore Applied
Technologies, Inc. ("Commodore"), William J. Russell ("Russell"), Tamie P.
Speciale ("Speciale") and Dispute Resolution Management, Inc. ("DRM"). Unless
otherwise expressly defined herein, all capitalized terms used in this letter
shall have the same meaning as is defined in the Purchase Agreement.

         In connection with the transactions contemplated by the Purchase
Agreement, Commodore acquired; 81% of the issued and outstanding shares of
capital stock of DRM from Russell and Speciale. It is acknowledged that,
pursuant to the terms of the Purchase Agreement, 35% of all DRM Cash Flow (as
defined) is subject to distribution to Russell and Speciale and the balance is
to be either retained by DRM for working capital and/or other corporate purposes
or, if approved by the board of directors of DRM and by Russell and Speciale,
may be distributed to Commodore as an intercompany dividend or loan.

         This will further acknowledge that prior to February 12, 2001, DRM
expects to receive from clients, one or more cash payments aggregating
approximately $4.0 million in connection with the settlement of environmental
claims.

         In order to induce the "Investors" to loan and advance up to $500,000
to Commodore pursuant to the terms of a securities purchase agreement, dated of
even date herewith (the "Investment Agreement"), DRM hereby agrees that

                  (a) as, if and when DRM shall receive payments from its
clients or from the insurer(s) in connection with such environmental claims, it
shall, promptly following receipt of such payments, distribute to Commodore,
either as an intercompany loan or dividend, not less than the sum of $500,000;
and

                  (b) as, if and when such distribution(s) are to be made to
Commodore, the initial $500,000 shall be remitted to Greenberg Traurig, LLP, as
attorneys for the benefit of the Investors, as follows:

                                TO: Citibank N.A.

         Nothing contained in this letter shall, in any manner, be deemed or
construed to constitute (i) a guaranty by DRM of any obligations of Commodore to
the Investors under the Investment Agreement or otherwise, (ii) any guaranty by

grant by DRM of any lien or security interest on any assets of DRM.

         It is expressly understood and agreed that DRM's only commitment
hereunder is to distribute to Commodore $500,000 of the total cash proceeds
received by DRM from the environmental settlement we anticipate receiving
between now and February 12, 2001 or thereafter; provided, that if for any
reason the aggregate amounts contemplated to be paid to DRM are materially
reduced, DRM and its board of directors are free to reduce the amounts to be
distributed to Commodore so as to (a) insure the payments to Russell and
Speciale contemplated by the Purchase Agreement, and (b) provide for reasonable
and necessary working capital for DRM.

         DRM acknowledges that its agreement and undertaking set forth herein is
a material inducement to enable Commodore to obtain financing from the Investors
and that the Investors are entitled to rely upon the covenants and agreements of
DRM contained herein.

Mr. Mack Jones
President
Commodore Advanced Sciences, Inc.
2340 Menaul Boulevard NE
Albuquerque, NM  87107

Dear Mr. Jones:

         On February 14, 2001, Commodore Advanced Sciences, Inc. (Commodore)
requested a renewal of the Commodore Applied Technologies, Inc., TSCA PCB
approval dated March 7, 1996, with two subsequent revisions (the latest on May
29, 1998). Commodore requested an amendment to this approval to include the S-10
reactor which was demonstrated in November 2000 in Harrisburg, Pennsylvania, and
a renewal for the continued operation of the L1200 and the Type S Reactors. The
Commodore approval expires on March 15, 2001.

         The demonstration test results are currently under review by the Office
of Pollution Prevention and Toxics (OPPT). The review is expected to be
completed by September 15, 2001. The approval will then be renewed for the
continued operation of the L1200 and Type S Reactors and amended to incorporate
the results from the November 2000 demonstration of the S-10 reactor. Approval
is contingent on acceptable results from the demonstration test and the permit
conditions being agreeable with Commodore.

         In the interim, a renewal of the TSCA PCB Disposal Approval dated May
29, 1998, is hereby granted to Commodore Advanced Sciences, Inc., of
Albuquerque, New Mexico to operate the L1200 and Type S Reactors as described by
the conditions in the May 29, 1998 Approval and is effective upon date of
signature. This approval shall expire on September 15, 2001.

         If you have any questions regarding this matter, please contact Winston
Lue of my staff at (202) 260-3962.

                                            Sincerely,

1.2      Commodore and WCS agree to cooperate with each other and coordinate the
         shipment of the equipment  described in Section 1.1 above and Exhibit A
         and the  preparation  of the Facility Site as described in this Section
         1.2 such that prior to the delivery of any equipment, the Facility Site

         not accept  materials for treatment that will result in a payment to it
         of less than $2.00 per pound.  Commodore  shall process all  conforming
         Materials to the specifications set forth on Exhibit A hereto.

2.3      Commodore  shall not  install  any other SET  equipment  or similar SET
         equipment  at  a  commercial  facility  for  processing  Material  that
         otherwise  could be processed at WCS using  Commodore's  SET  equipment
         unless WCS provides written consent to Commodore for each such Material
         to be  processed.  Such request for written  consent  shall trigger the
         following right:

         2.3.1  WCS shall have the sole elective right upon Commodore's  request
                for consent to:

                         purchase  under this  provision,  WCS may contract with
                         Commodore  for  additional   services  related  to  the

2.0      PROCESS CAPABILITIES AND MATERIAL SPECIFICATIONS
---      ------------------------------------------------

2.1      General Process Capabilities

         Commodore's  solvated  electron  technology (SET) is a patented process
         for  the  reductive  destruction  of  many  organic  molecules  and  is
         extremely  effective  in  the  dehalogenation  of  halogenated  organic
         compounds.  In the process,  contaminants  are  destroyed by a chemical
         reduction  mechanism,  whereby the  functional  organic  compounds  are
         converted to petroleum hydrocarbons and metal salts.

         In application, contaminated materials are placed into a treatment cell
         and mixed with a solvated electron  solution.  Chemical  reactions then
         strip the halogen ions and reduce the organic  compound.  At the end of
         the  reaction,  ammonia  within  the  treatment  cell  is  removed  and
         recycled.

         Commodore  will place  Conforming  Materials  received  from WCS (using
         either a lift machine or other conveying mechanism) into the D/2 and/or
         S-10  treatment  cell and mix the  material  with a  solvated  electron
         solution. Chemical reactions then strip the halogen ions and reduce the
         organic  compound.  At the  end of the  reaction,  ammonia  within  the
         treatment cell is removed and recycled.

2.2      Conforming Material Specifications

         Commodore's   SET  D/2  and  S-10  system(s)  has  been  successful  at
         remediating  a wide variety of toxic  chemicals.  For the WCS treatment
         installation, the following criteria must be met for successful, single
         run  treatment  with the goal to remove the organic  constituent(s)  to
         below regulatory limits: The target compound to be treated must be able
         to be chemically reduced.

         (1) The total reducible organic contaminants to be treated are equal to
             or less than 20,000 ppm.

         (2) Total water content is less than or equal to 25%.

                                       18
<PAGE>

         (3) No size  reduction of material is required.  Material  must be less
             than 6" in diameter when delivered to the system.

         (4) The waste  stream  and any of its  constituent(s)/target  compounds
             must not be shock-sensitive.

         (7) Such other criteria as Commodore, in its exercise of scientific and
             reasonable discretion, shall establish.

                                ----------------

For the destruction of organic material (i.e., PCBs, dioxins, etc.) in various
waste streams utilizing Commodore's SET process and D/2 and S-10 processing
equipment, the pricing per pound processed is as indicated below.

The basis for this pricing has been estimated on material characteristics and
contaminant concentrations as published as part of the Broad Spectrum
procurement RFP of January 1998. In addition, the waste to be treated must meet
the specifications as noted in the process description, specifically that total
reducible organic contaminants for material to be treated are equal to, or less
than 20,000 ppm, the total water content is less than 25%, and no size reduction
of material is required. Additional process runs (i.e., additional cost) will be
needed for greater material that exceed these limits, and costing will be
determined on a case by case basis.

                  WCS Price to Customer (per pound)
                  ---------------------------------    ------------------------
                             $6.00 - $12.00              Greater than $12.00
