     extent that such Joint Intellectual Property pertains to the MCP per se
     that ADA-ES is capable of providing, it shall be owned by ADA-ES; and to
     the extent that such Joint Intellectual Property pertains to the ECS per se
     that ALSTOM has the expertise to supply, such Joint Intellectual Property
     shall be owned by ALSTOM. Similarly, the Joint Intellectual Property Rights
     for the Joint Intellectual Property, which is owned by ADA-ES, shall be
     owned by ADA-ES, and the Joint Intellectual Property Rights for the Joint
     Intellectual Property, which is owned by ALSTOM, shall be owned by ALSTOM.

3.2 Licenses. Subject to the licensing restrictions and reservation of rights
contained herein, each of the Parties intends to commercially exploit the MCP
and the Intellectual Property relating thereto. Therefore, to the extent
required in order to effect such commercial exploitation of the MCP, each of the
Parties grants to the other Party the licensing rights set forth below.

     3.2.1 ADA-ES Grants. ADA-ES hereby grants to ALSTOM:

     (a)  Marketing License. An Exclusive Marketing License under ADA-ES'
          Intellectual Property specifically directed to the MCP (including
          Joint Intellectual Property created during the term of this Agreement
          and owned by ADA-ES for the MCP) to the extent necessary for the
          commercial use and exploitation by ALSTOM of the MCP.

     (b)  Additionally, ADA-ES grants to ALSTOM a limited, royalty-free license
          under ADA-ES' Intellectual Property to use certain of ADA-ES'
          Intellectual Property in order for ALSTOM to exploit as contemplated
          by this Agreement the MCP.

     3.2.2 ALSTOM Grants. ALSTOM hereby grants to ADA-ES:

          and owned by ALSTOM for the MCP) to the extent necessary for the
          commercial use and exploitation by ADA-ES of the MCP.

     (b)  Additionally, ALSTOM grants to ADA-ES a limited, royalty-free license
          under ALSTOM's Intellectual Property to use certain of ALSTOM's
          Intellectual Property in order for ADA-ES to exploit as contemplated
          by this Agreement the MCP.


3.3 This exclusive marketing and exploitation relationship shall be exclusive
except;

     3.3.1 In those cases where after diligent effort the proposed client will
     not accept the ECS that ALSTOM proposes to supply to the client or the
     proposed client will not accept the MCP that ADA-ES proposes to provide to
     the client. In such an event, the Party that is acceptable to the customer
     may pursue its own limited scope on an individual basis.

<PAGE>

     3.3.2 Sales of the MCP only that do not include ECS. ADA-ES shall be free
     to respond to requests for quotations for MCPs and to supply MCPs to any
     Industrial, Utility and power plant applications for engineering companies
     and other air pollution control vendors where the request and supply by
     ADA-ES does not include ECS.

     3.3.3 Sales of ECS only that do not include the MCP. ALSTOM shall be free
     to respond to requests for quotations for ECS and to supply ECSs to any
     Industrial, Utility and power plant applications for engineering companies
     and other air pollution control vendors where the request and supply by
     ALSTOM does not include MCP.

     3.3.4 Prior business relationships, if any, as designated in attached
     Schedule 3. After execution of the Agreement, any additional exclusions
     will be mutually agreed upon between the parties through the designated
     marketing channels as they are identified.

4.0 Joint Commercial Offerings

4.1 The Parties agree that ALSTOM shall take the lead in preparing a proposal to
the client for joint commercial offerings of the MCP packaged with an ECS,
provided however, if particular circumstances indicate for a specific project
that this is not the most advantageous approach to achieve a sale, then the
Parties will mutually decide if ADA-ES will be the lead Party, or an alternate
approach will be followed, for purposes of submitting such proposal to the
client for such project.

4.2 Each Party will cooperate with the other Party in determining the
appropriate division of work between the Parties, and in supplying the client
with the required ECS and services in the case of ALSTOM and in providing the
client with the required MCP in the case of ADA-ES to meet the client's
specifications and/or requirements. Each party shall be fully responsible for
the performance and deficiencies of its respective scope of supply as set forth
in the division of work in Schedule 1. The Parties further agree that for each
particular joint commercial offering, (i) each Party shall adapt and refine, as
appropriate, its respective division of work based on the form in Schedule 1 for
the specific requirements of the customer and project (e.g. coal type, gas flow
and duct design); and (ii) commercial terms and conditions as between the
Parties, including any warranties, guarantees, and remedies and limitations for
any breaches thereto, shall be mutually agreed upon in a subcontract or other
definitive agreement executed by the Parties. Such agreement between the Parties
shall be entered into with due consideration of the respective terms and
conditions in the sales agreement with the customer which results from the joint
commercial offering. Notwithstanding the foregoing and for the avoidance of
doubt, nothing contained herein shall require a Party to commit to or be
obligated to perform any particular term of sale that it does not agree to offer
or to be bound by as evidenced by the subcontract or other definitive agreement
between the Parties, or as otherwise indicated in the joint commercial offering.

4.3 The non-lead Party will compile and submit to the lead Party for inclusion
in the proposal to the client all technical information as well as warranty and
guarantee information to the extent that all such information may be required
from the non-lead Party, and the non-lead Party's pricing for the non-lead
Party's scope of supply. Neither Party will make any changes to the other
Party's scope of supply unless such action has been specifically agreed to in
writing by both Parties prior to their submission of such proposal to the
client.

4.4 Most Favorable Pricing discount. ADA-ES agrees that for all joint commercial
offerings in which ADA-ES's scope will be offered as a subcontractor to ALSTOM,
ADA shall provide ALSTOM with a discounted price on its scope of work equal to
5% less than the lowest price that ADA-ES would otherwise quote for the MCP such
that, with the discount of 5%, ALSTOM receives the most favorable price from
ADA-ES than any of its other customers who may be permitted to purchase an MCP
directly from ADA-ES pursuant to paragraph 3.3 above, or from sales not
otherwise precluded by virtue of this Agreement.

5.0 Exploitation

5.1 ALSTOM and ADA-ES plan to exploit potential applications for employing ECS
and MCP for the removal of mercury from the flue gas generated from the
combustion of fossil fuels. The Parties agree to meet at least annually to
establish the goals for such exploitation for that year and, if appropriate, for
subsequent years as well. Each Party agrees to fund its own portion of the
effort involved in such exploitation work. The Parties shall also mutually agree
on whether to seek third party exploitation funding and, if the Parties should
so mutually agree, on the type of such funding and on the identity of the third
party funding entity from whom such third party exploitation funding would be
sought.

5.2 Sales Objectives. The Parties agree to meet periodically to coordinate and
select sales opportunities as well as to coordinate the joint sales and
marketing activities of both Parties as contemplated in 5.1 above. Each Party
shall be responsible for funding its own portion of the effort involved both in
coordinating and selecting such sales opportunities and in coordinating such
joint sales and marketing activities.

5.3 Auditing. No more than once per calendar year, each Party may employ an
independent Third Party auditor to perform a reasonable inspection and audit of
the books, records and systems of the other Party hereto to verify compliance by
the other Party with this Exploitation Agreement. Notwithstanding the foregoing,
the scope of the audit to be conducted by such independent Third Party auditor
shall be limited to the other Party's performance under this Exploitation
Agreement, and in particular the obligations set forth in Sections 3, 4, and 5,
and the scope shall not be broadened to include unrelated business segments of
the other Party or the other Party's global financial performance. The audited
Party agrees to cooperate in such inspections and audits. All such audits by the
independent Third Party auditor shall be conducted during normal business hours
and with at least 7 days advance written notice from the auditing Party to the
Party that is to be audited. Each Party shall bear its own costs and expenses in
connection with the conducting of such an audit by such an independent Third
Party auditor.
