                           Memorandum of Understanding

1.       Parties:

         Lockheed Martin Advanced Environmental Systems Inc., a corporation
         established under the laws of the state of Delaware, having offices
         at 201 Third St. NW, Suite 1600, Albuquerque, NM 87102 (herein after
         called LMAES).

         Commodore Advanced Sciences, Inc., a corporation established under
         the laws of Virginia, having offices at 6867 Elm Street, McLean, VA
         22101, (herein after referred to as "CAS").

2.       Purpose:

         a.  The purpose of this agreement is to set forth understandings
             under which LMAES and CAS will evaluate, for possible teamed
             effort by the parties, potential projects and contracts related
             to cooperative efforts in the pursuit of mutually beneficial
             projects related to Commodore's Solvated Electron Technology
             (SET(TM)) and particular expertise and complementary technologies
             of LMAES. Projects in these areas may include environmental
             investigations, waste characterization, remedial investigations,
             feasibility studies, remediation, demilitarization, and research
             and development.

         b.  In the event the parties determine on a case by case basis to
             work with each other for a particular project (e.g. a request for
             a proposal by the United States Government or other entities) the
             parties will seek to negotiate a separate teaming agreement for
             each such project.

3.       Objectives:

         a.  It is the intent of both Parties to cooperate in a business
             arrangement to pursue opportunities with the SET(TM) technology
             for mixed and hazardous waste. Should a contract result from
             these activities, the Parties agree to enter into a formal
             teaming arrangement where the rights and responsibilities of both
             Parties will be clearly identified.

         b.  A further objective is to work together to develop a "History" of
             working together on field projects that will add value in
             pursuing future work together.

         c.  As an integral part of the overall objectives, performing a
             project or projects together will be the initial step.

4.   Validation of SET(TM) Technology

     (a)  CAS will validate the SET(TM) technology under field conditions,
          provide details on unit operability and maintainability in the DOE or
          DOD environment, verify previous testing and results regarding
          scalability, and provide operating data as to SET(TM)'s applicability
          to integrate the process into other treatment trains that LMAES has,
          or has access to, when required. In addition, CAS will validate for
          LMAES their previous test results on destruction, identification of
          by-products from the reactions (and verification of their benign
          nature) and, in the case of mixed waste, how the process may reduce
          and concentrate certain radioactive materials from soil. Ideally, the
          demonstration would show SET(TM)'s versatility in dealing with various
          waste forms such as soils, liquids and miscellaneous heterogenous
          waste streams such as job control material.

     (b)  In conjunction with demonstrating and verifying the technical aspects
          of the SET(TM) process, site support issues will be validated. These
          include material handling, radiological engineering in design and
          implementation of radiological controls, industrial hygiene controls,
          and safety procedures in using the ammonia and sodium metal during
          process applications.

     (c)  To assist in effectively and expeditiously implementing this MOU,
          LMAES agrees to enter into a research and development contract with
          CAS in an amount not to exceed $50,000, with planned effective date in
          January of 1998, to treat contaminated material and validate SET(TM)
          Technology against specific expected results (to be finalized and
          agreed to before activation of contract). In support of this R&D
          contract, CAS will provide an equivalent amount of "Like Kind" value
          ($50K) in equipment, operators, consumables, laboratory testing, etc.
          to aid the success of the treatability studies and customer site
          demonstration.

     (d)  The intent of this R&D contract is to demonstrate the benefits to be
          derived from use of the SET(TM) Technology in the decontamination of
          soil and/or drummed material. Some amount of contaminated material may
          be shipped to the LMAES Material Treatability Laboratory, in Las
          Vegas, NV, to evaluate contaminant bonding and particle size
          distribution. This will be followed by treatability studies using the
          SET(TM) Technology, provided by CAS in conjunction with other pre and
          post processors, as required, to assess results.

5.   Business Opportunities

     (a)  Following successful treatability studies, LMAES and CAS will plan to
          schedule demonstration at a selected customer site.

     (b)  A projected near-term customer is Y-12 (Oak Ridge) contaminated soil
          and

                                       2

<PAGE>


          job control material. Follow-on opportunities at the Portsmouth, Ohio
          facility will be predicated on successful demonstration and validation
          activities at Oak Ridge Y-12 facility or other facilities.

     (c)  Both parties mutually agree to identify, during the 4th quarter of
          1997 and 1st quarter 1998, the clients and projects that they will
          initially pursue together during the term of this MOU. These will
          include, but not necessarily be limited to, the Department of Energy,
          Department of Defense, International and LMC.

     (d)  Upon successful completion of all demonstration and validation
          provided for herein the two parties will further define potential
          customers to be targeted for further business opportunities.

6.   Marketing

     (a)  Both Parties shall submit to each other all appropriate technical and
          business data and information concerning its technical and business
          history, including reasonable cost or pricing data, for use in
          developing strategies leading to a favorable competitive position with
          respect to the client's opportunities. Both Parties shall make
          available appropriate and high-quality personnel to provide reasonable
          assistance to each other in the preparation of presentations,
          meetings, strategy sessions, and proposals. Further, both Parties will
          continue to work together toward these objectives throughout any
          subsequent evaluations, presentations, submittal, and best and final
          request concerning the pursuit of contracts which may follow the
          submission of the proposals. Both Parties agree that their portion of
          the project scopes is subject to negotiation.

     (b)  In pursuit of the program it is agreed that both Parties will jointly
          develop specific marketing and pricing strategies. The Parties will
          meet at those times which are necessary to discuss progress and status
          of their technical documentation; and cooperate in the exchange of
          data which may be necessary to aid in the development of briefings.
          Both Parties will also provide a person at each company to serve as a
          primary designated focal point of the effort. For LMAES, that person
          shall be Ed Brown at (505) 924-2588; for CAS that person shall be
