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

As 'indicated on the face page, Block 18c, this Award is subject to the DOE
Assistance Regulations of Title 1O, Code of Federal Regulations, Part 600. This
set of regulations may be found in most major libraries or on the World Wide Web
at:

                       http://www.pr.doe.gov/fahome.htmi

2.2 ORDER OF PRECEDENCE (DEC 1999)
----------------------------------

In the event of any inconsistency among the provisions of this agreement, the
inconsistency shall be resolved by giving precedence as follows: (a) Applicable
Public Laws; (b) the special terms and conditions or schedule of articles; (c)
10 CFR Part 600; and (d) other documents, exhibits and attachments.

2.3 SUBSTANTIAL INVOLVEMENT BETWEEN DOE AND THE RECIPIENT (JAN 1999)
--------------------------------------------------------------------

There will be substantial involvement between the DOE and the Recipient during
performance of this Cooperative Agreement. The DOE will participate in review
and approval during the project period of one stage before work can begin on a
subsequent stage, thereby sharing the responsibility for the direction of the
project. In addition, the DOE will share responsibility for the management of
the project as further described in this section. The substantial involvement
anticipated between DOE and the Participant consists of (1) involvement in the
technical and business management aspects of the project, (2) substantial
involvement and contribution to the technical aspects of the work necessary for
its accomplishment, and (3) review and approval during the project period of one
stage before work can begin on a subsequent stage(ie, DOE will participate in
establishing and approving a work plan, which will be used to identify essential
and significant milestones necessary of completion of the project. This plan
will be used to determine whether or not to proceed with subsequent tasks in the
statement of project objectives).

a. Recipient Role
   --------------

          The Recipient shall be responsible for all aspects of project
          performance as set forth in the Application dated 4-26-00 as revised.
          All services, personnel, facilities, equipment, materials, and
          supplies shall be furnished by the Recipient, unless otherwise
          specified under this Cooperative Agreement.

          The Recipient shall designate a Project Manager who shall serve as its
          authorized representative for the technical and administrative
          elements of all work to be performed under this Cooperative Agreement.
          The Project Manager shall be the single authorized point of contact
          for all communications between the Recipient and the DOE.

b. DOE Role
   --------

          DOE shall monitor the Recipient's progress in performing the project
          and shall have a substantial role in project decision making.

          The DOE Contracting Officer is the only Government Representative
          authorized to accept the reports and other deliverables the Recipient
          is required to provide under this Cooperative Agreement. The review
          and comment of such reports and other deliverables may be delegated to
          the Contracting Officer's authorized representative (COR).

          The DOE Contracting Officer shall designate a COR who shall have the
          authority to issue written technical advice which suggests redirecting
          the project work (e.g., by changing the emphasis among different
          tasks), or pursuing specific lines of inquiry likely to assist in
          accomplishing the Statement of Work. The COR shall have the authority
<PAGE>

          to comment on those technical reports, plans, and other technical
          information the Recipient is required to submit to DOE for review and
          comment. The COR is not authorized to issue, and the Recipient is not
          required to follow, any technical advice which constitutes work which
          is not within the scope of the Statement of Work; which in any manner
          causes an increase or decrease in the total estimated cost or in the
          time required for performance of the project; which has the effect of
          changing any of the terms or conditions of the Cooperative Agreement;
          or which interferes with the Recipient's right to perform the project
          in accordance with the terms and conditions of this Cooperative
          Agreement.

c. No Government Obligation to Third Paties
   ----------------------------------------

          In connection with the performance of the project, the Government
          shall have no obligation or responsibility to any contractor,
          subcontractor or other person who is not a party to this Cooperative
          Agreement. The foregoing limitation shall apply notwithstanding the
          Contracting Officer's prior approval or consent of any contract
          awarded by the Recipient. The Recipient shall be responsible, without
          recourse to DOE, except for amounts DOE is otherwise obligated to pay
          pursuant to the provisions of this Cooperative Agreement for the
          resolution and satisfaction of all pre-award protests, contract
          administration issues, and contract disputes arising out of
          acquisitions related to the Project.

2.4 COST SHARING (May 2000)
---------------------------

The total estimated cost of the project for the work to be accomplished under
this award is $6,779,946.00. The Recipient and the Government agree to share the
allowable project costs under this award as follows:

     (b) Allocation of principal rights. The Contractor may retain the entire
     right, title, and interest throughout the world to each subject invention
     subject to the provisions of this clause and 35 U.S.C. 203. With respect to
     any subject invention in which the Contractor retains title, the Federal
     Government shall have a nonexclusive, nontransferable, irrevocable, paid-up
     license to practice or have practiced for or on behalf of the United States
     the subject invention throughout the world.

     (c) Invention disclosure, election of title, and filing of patent
     application by Contractor.

          (1) The Contractor will disclose each subject invention to the
          Department of Energy (DOE) within 2 months after the inventor
          discloses it in writing to Contractor personnel responsible for patent
          matters. The disclosure to DOE shall be in the form of a written
          report and shall identify the contract under which the invention was
          made and the inventor(s). It shall be sufficiently complete in
          technical detail to convey a clear understanding to the extent known
          at the time of the disclosure, of the nature, purpose, operation, and
          the physical, chemical, biological or electrical characteristics of
          the invention. The disclosure shall also identify any publication, on
          sale or public use of the invention and whether a manuscript
          describing the invention has been submitted for publication and, if
          so, whether it has been accepted for publication at the time of
          disclosure. In addition, after disclosure to the DOE, the Contractor
          will promptly notify that agency of the acceptance of any manuscript
          describing the invention for publication or of any on sale or public
          use planned by the Contractor.

          (2) The Contractor will elect in writing whether or not to retain
          title to any such invention by notifying DOE within 2 years of
          disclosure to DOE. However, in any case where publication, on sale or
          public use has initiated the I-year statutory period wherein valid
          patent protection can still be obtained in the United States, the
          period for election of title may be shortened by DOE to a date that is
          no more than 60 days prior to the end of the statutory period.

          (3) The Contractor will file its initial patent application on a
          subject invention to which it elects to retain title within 1 year
          after election of title or, if earlier, prior to the end of any
          statutory period wherein valid patent protection can be obtained in
          the United States after a publication, on sale, or public use. The
          Contractor will file patent applications in additional countries or
          international patent offices within either 10 months of the
          corresponding initial patent application or 6 months from the date
          permission is granted by the Commissioner of Patents and Trademarks to
          file foreign patent applications where such filing has been prohibited
          by a Secrecy Order.

          (4) Requests for extension of the time for disclosure, election, and
          filing under subparagraphs (c)(I), (2), and (3) of this clause may, at
          the discretion of the agency, be granted.

(d) Conditions when the Government may obtain title. The Contractor will convey
to the Federal agency, upon written request, title to any subject invention--

          (1) If the Contractor fails to disclose or elect title to the subject
          invention within the times specified in paragraph (c) of this clause,
          or elects not to retain title; provided, that DOE may only request
          title within 60 days after learning of the failure of the Contractor
          to disclose or elect within the specified times.

          (2) In those countries in which the Contractor fails to file patent
          applications within the times specified in paragraph (c) of this
          clause; provided, however, that if the Contractor has filed a patent
          application in a country after the times specified in paragraph (c) of
          this clause, but prior to its receipt of the written request of the
          Federal agency, the Contractor shall continue to retain title in that
          country.

<PAGE>

          (3) In any country in which the Contractor decides not to continue the
          prosecution of any application for, to pay the maintenance fees on, or
          defend in reexamination or opposition proceeding on, a patent on a
          subject invention.

     (e) Minimum rights to Contractor and protection of the Contractor right to
     file.

          (1) The Contractor will retain a nonexclusive royalty-free license
          throughout the world in each subject invention to which the Government
          obtains title, except if the Contractor fails to disclose the
          invention within the times specified in paragraph (c) of this clause.
          The Contractor's license extends to its domestic subsidiary and
          affiliates, if any, within the corporate structure of which the
          Contractor is a party and includes the right to grant sublicenses of
          the same scope to the extent the Contractor was legally obligated to
          do so at the time the contract was awarded. The license is
          transferable only with the approval of the Federal agency, except when
          transferred to the successor of that part of the Contractor's business
          to which the invention pertains.

          (2) The Contractor's domestic license may be revoked or modified by
          DOE to the extent necessary to achieve expeditious practical
          application of subject invention pursuant to an application for an
          exclusive license submitted in accordance with applicable provisions
          at 37 CFR Part 404 and agency licensing regulations. This license will
          not be revoked in that field of use or the geographical areas in which
          the Contractor has achieved practical application and continues to
          make the benefits of the invention reasonably accessible to the
          public. The license in any foreign country may be revoked or modified
          at the discretion of DOE to the extent the Contractor, its licensees,
          or the domestic subsidiaries or affiliates have failed to achieve
          practical application in that foreign country.

          (3) Before revocation or modification of the license, DOE will furnish
          the Contractor a written notice of its intention to revoke or modify
          the license, and the Contractor will be allowed 30 days (or such other
          time as may be authorized by DOE for good cause shown by the
          Contractor) after the notice to show cause why the license should not
          be revoked or modified. The Contractor has the right to appeal, in
          accordance with applicable regulations in 37 CFR Part 404 and agency
          regulations concerning the licensing of Government owned inventions,
          any decision concerning the revocation or modification of the license.

     (f) Contractor action to protect the Government's interest.

          (1) The Contractor agrees to execute or to have executed and promptly
          deliver to DOE all instruments necessary to (i) establish or confirm
          the rights the Government has throughout the world in those subject
          inventions to which the Contractor elects to retain title, and (ii)
          convey title to DOE when requested under paragraph (d) of this clause
          and to enable the government to obtain patent protection throughout
          the world in that subject invention.

          (2) The Contractor agrees to require, by written agreement, its
          employees, other than clerical and nontechnical employees, to disclose
          promptly in writing to personnel identified as responsible for the
          administration of patent matters and in a format suggested by the
          Contractor each subject invention made under contract in order that
          the Contractor can comply with the disclosure provisions of paragraph
          (c) of this clause, and to execute all papers necessary to file patent
          applications on subject inventions and to establish the Government's
          rights in the subject inventions. This disclosure format should
          require, as a minimum, the information required by subparagraph (c)(1)
          of this clause. The Contractor


<PAGE>


          shall instruct such employees, through employee agreements or other
          suitable educational programs, on the importance of reporting
          inventions in sufficient time to permit the filing of patent
          applications prior to U.S. or foreign statutory bars. (3) The
          Contractor will notify DOE of any decision not to continue the
          prosecution of a patent application, pay maintenance fees, or defend
          in a reexamination or opposition proceeding on a patent, in any
          country, not less than 30 days before the expiration of the response
          period required by the relevant patent office.

          (4) The Contractor agrees to include, within the specification of any
          United States patent application and any patent issuing thereon
          covering a subject invention, the following statement, "This invention
          was made with Government support under (identify the contract) awarded
          by the United States Department of Energy. The Government has certain
          rights in the invention."

     (g) Subcontracts.

          (1) The Contractor will include this clause, suitably modified to
          identify the parties, in all subcontracts, regardless of tier, for
          experimental, developmental, or research work to be performed by a
          small business firm or domestic nonprofit organization. The
          subcontractor will retain all rights provided for the Contractor in
          this clause, and the Contractor will not, as part of the consideration
          for awarding the subcontract, obtain rights in the subcontractor's
          subject inventions.

          (2) The contractor shall include in all other subcontracts, regardless
          of tier, for experimental, developmental, demonstration, or research
          work the patent rights clause at952.227-13.

          (3) In the case of subcontracts, at any tier, DOE, subcontractor, and
          the Contractor agree that the mutual obligations of the parties
          created by this clause constitute a contract between the subcontractor
          and DOE with respect to the matters covered by the clause; provided,
          however, that nothing in this paragraph is intended to confer any
          jurisdiction under the Contract Disputes Act in connection with
          proceedings under paragraph 0) of this clause.

          (h) Reporting on utilization of subject inventions. The Contractor
          agrees to submit, on request, periodic reports no more frequently than
          annually on the utilization of a subject invention or on efforts at
          obtaining such utilization that are being made by the Contractor or
          its licensees or assignees. Such reports shall include information
          regarding the status of development, date of first commercial sale or
          use, gross royalties received, by the Contractor, and such other data
          and information as DOE may reasonably specify. The Contractor also
          agrees to provide additional reports as may be requested by DOE in
          connection with any march-in proceeding undertaken by that agency in
          accordance with paragraph (j) of this clause. As required by 35 U.S.C.
          2O2(c)(5), DOE agrees it will not disclose such information to persons
          outside the Government without permission of the Contractor.

          (i) Preference for United States industry. Notwithstanding any other
          provision of this clause, the Contractor agrees that neither it nor
          any assignee will grant to any person the exclusive right to use or
          sell any subject invention in the United States unless such person
          agrees that any product embodying the subject invention or produced
          through the use of the subject invention will be manufactured
          substantially in the United States. However, in individual cases, the
          requirement for such an agreement may be waived by DOE upon a showing
          by the Contractor or its assignee that reasonable but unsuccessful
          efforts have been made to grant licenses on similar terms to potential
          licensees that would be likely to manufacture substantially in the
          United States or that under the circumstances domestic manufacture is
          not commercially feasible.


<PAGE>


     0) March-in rights. The Contractor agrees that, with respect to any subject
     invention in which it has acquired title, DOE has the right in accordance
     with the procedures in 37 CFR 401.6 and any supplemental regulations of the
     agency to require the Contractor, an assignee or exclusive licensee of a
     subject invention to grant a nonexclusive, partially exclusive, or
     exclusive license in any field of use to a responsible applicant or
     applicants, upon terms that are reasonable under the circumstances, and, if
     the Contractor, assignee, or exclusive licensee refuses such a request, DOE
     has the right to grant such a license itself if DOE determines that--

          (1) Such action is necessary because the Contractor or assignee has
          not taken, or is not expected to take within a reasonable time,
          effective steps to achieve practical application of the subject
          invention in such field of use;

          (2) Such action is necessary to alleviate health or safety needs which
          are not reasonably satisfied by the Contractor, assignee, or their
          licensees;

          (3) Such action is necessary to meet requirements for public use
          specified by Federal regulations and such requirements are not
          reasonably satisfied by the Contractor, assignee, or licensees; or (4)
          Such action is necessary because the agreement required by paragraph
          (i) of this clause has not been obtained or waived or because a
          licensee of the exclusive right to use or sell any subject invention
          in the United States is in breach of such agreement.


     (k) Special provisions for contracts with nonprofit organizations. If the
     Contractor is a nonprofit organization, it agrees that--

          (1) Rights to a subject invention in the United States may not be
          assigned without the approval of the Federal agency, except where such
          assignment is made to an organization which has as one of its primary
          functions the management of inventions; provided, that such assignee
          will be subject to the same provisions as the Contractor;

          (2) The Contractor will share royalties collected on a subject
          invention with the inventor. including Federal employee co-inventors
          (when DOE deems it appropriate) when the subject invention is assigned
          in accordance with 35 U.S.C. 202(e) and 37 CFR 401.10;

          (3) The balance of any royalties or income earned by the Contractor
          with respect to subject inventions, after payment of expenses
          (including payments to inventors) incidental to the administration of
          subject inventions will be utilized for the support of scientific
          research or education; and

          (4) It will make efforts that are reasonable under the circumstances
          to ~ttract licensees of subject inventions that are small business
          firms, and that it will give a preference to a small business firm
          when licensing a subject invention if the Contractor determines that.
          the small business firm has a plan or proposal for marketing the
          invention which, if executed, is equally as likely to brrng the
          invention to practical application as any plans or proposals from
          applicants that are not small business firms; provided, that the
          Contractor is also satisfied that the small business firm has the
          capability and resources to carry out its plan or proposal. The
          decision whether to give a preference in any specific case will be at
          the discretion of the contractor. However, the Contractor agrees that
          the Secretary of Commerce may review the Contractor's licensing
          program and decisions regarding small business applicants, and the
          Contractor will negotiate changes to its licensing policies,
          procedures, or practices with the Secretary of Commerce when that
          Secretary's review discloses that the Contractor could take reasonable
          steps to more effectively implement the requirements of this
          subparagraph (k)(4).

     (e) Unauthorized marking of data.

          (1) Notwithstanding any other provisions of this contract concerning
          inspection or acceptance, if any data delivered under thIs contract
          are marked with the notices specified in subparagraph (g)(2) or (g)(3)
          of this clause and use of such is not authorized by this clause, or if
          such data bears any other restrictive or limiting markings not
          authorized by this contract, the Contracting Officer may at any time
          either return the data to the Contractor, or cancel or ignore the
          markings. However, the following procedures shall apply prior to
          canceling or ignoring the markings.

               (i) The Contracting Officer shall make written inquiry to the
               Contractor affording the Contractor 30 days from receipt of the
               inquiry to provide written justification to substantiate the
               propriety of the markings;

               (ii) If the Contractor fails to respond or fails to provide
               written justification to substantiate the propriety of the
               markings within the 30-day period (or a longer time not exceeding
               90 days approved in writing by the Contracting Officer for good
               cause shown), the Government shall have the right to cancel or
               ignore the markings at any time after said period and the data
               will no longer be made subject to any disclosure prohibitions.

               (iii) If the Contractor provides written justification to
               substantiate the propriety of the markings within the period set
               in subdivision (e)(1)(i) of this clause, the Contracting Officer
               shall consider such written justification and determine whether
               or not the markings are to be canceled or ignored. If the
               Contracting Officer determines that the markings are authorized,
               the Contractor shall be so notified in writing. If the
               Contracting Officer determines, with concurrence of the head of
               the contracting activity, that the markings are not authorized,
               the Contracting Officer shall furnish the Contractor a written
               determination, which determination shall become the final agency
               decision regarding the appropriateness of the markings unless the
               Contractor files suit in a court of competent jurisdiction within
               90 days of receipt of the Contracting Officer's decision. The
               Government shall continue to abide by the markings under this
               subdivision (e)(1 )(iii) until final resolution of the matter
               either by the Contracting Officer's determination becoming final
               (in which instance the Government shall thereafter have the right
               to cancel or ignore the markings at any time and the data will no
               longer be made subject to any disclosure prohibitions), or by
               final disposition of the matter by court decision if suit is
               filed.

          (2) The time limits in the procedures set forth in subparagraph (e)(1)
          of this clause may be modified in accordance with agency regulations
          implementing the Freedom of Information Act (5 U.S.C. 552) if
          necessary to respond to a request thereunder.

          (3) This paragraph (e) does not apply if this contract is for a major
          system or for support of a major system by a civilian agency other
          than NASA and the U.S. Coast Guard agency subject to the provisions of
          Title III of the Federal Property and Administrative Services Act of
          1949.

          (4) Except to the extent the Government's action occurs as the result
          of final disposition of the matter by a court of competent
          jurisdiction, the Contractor is not precluded by this paragraph (e)
          from bringing a claim under the Contract Disputes Act, including
          pursuant to the Disputes clause of this contract, as applicable, that
          may arise as the result of the Government removing or ignoring
          authorized markings on data delivered under this contract.

     (f) Omitted or incorrect markings.

          (1) Data delivered to the Government without either the limited rights
          or restricted rights notice as authorized by paragraph (g) of this
          clause, or the copyright notice required by paragraph (c) of this
          clause, shall be deemed to have been furnished with unlimited rights,
          and the Government assumes no liability for the disclosure, use, or
          reproduction of such data. However, to the extent the data has not

          and (iii) of this clause are specified to be delivered under this
          contract and qualify as either limited rights data or restricted
          computer software, if the Contractor desires to continue protection of
          such data, the Contractor shall withhold such data and not furnish
          them to the Government under this contract. As a condition to this
          withholding, the Contractor shall identify the data being withheld and
          furnish form, fit, and function data in lieu thereof. Limited rights
          data that are formatted as a computer data base for delivery to the
          Government are to be treated as limited rights data and not restricted
          computer software.

          (2) (Reserved)

                 Statement of Cooperative Agreement Objectives

A. Objectives
   ----------

The overall objective of this project is to determine the cost and impacts of
sorbent injection into particulate control devices for various mercury removal
levels at field-scale, coal-fired power plants.

B. Scope of Work
   -------------

The scope of work is for one, three-year long budget period and intended to
provide the necessary information to assess the costs of controlling mercury
from coal-fired utilities by examining the economics of various levels of
mercury control (at different temperatures) at four different host sites.
Testing will be conducted on a minimum of three different configurations that
represent a significant percentage of existing units. These configurations will
include the following: an electrostatic precipitator collecting ash from a
powder river basin subbituminous coal; electrostatic precipitators collecting
ash from a low-sulfur eastern bituminous coal burned in low-NOx burners with
selective non-catalytic reduction (SNCR); and a baghouse configuration filtering
ash from powder river basin subbituminous coal. The subsequent cost analyses
will include capital costs, byproduct utilization issues, sorbent usage, any
necessary enhancements, such as S03 control or flue gas conditioning, balance of
plant, manpower requirements and waste issues.

C. Statement of Work
   -----------------

The program is divided into 13 tasks. Each task addresses one or more of the
program objectives. A description of these tasks is presented below.

Task 1 - Design and Fabrication of Transportable Mercury Control System
-----------------------------------------------------------------------

The participant shall design a transportable mercury control system with the
ability to provide both humidification and carbon/sorbent injection to a minimum
of two flue gas ducts simultaneously. Components shall be skid or panel mounted
for relatively quick and easy set-


<PAGE>


up/tear-down at each site. This system shall be sized and designed to cover the
range of plant TThis system shall have the ability to be operated with both
baghouses and electrostatic precipitators. The participant shall design and size
humidification injection lances for each plant application separately based on
duct dimensions and water flow requirements. The sorbent injection system shall
provide high flow (100-1500 lbs./hr) and low flow (10-200 lbs./hr) capability
depending on the amount of required sorbent injection. The participant shall
hold a design review meeting including the DOE COR, equipment suppliers, and
site-specific engineers before finalizing the transportable mercury control
system design and fabrication. The participant shall submit the final design
specifications to the DOE COR. After design specifications are finalized, the
participant shall fabricate the transportable mercury control system. Any
host-site components that are necessary to interface with the transportable
mercury control system shall be identified at least forty-five days prior to the
start of the scheduled host site field test to allow adequate design time to
accommodate the specific plant arrangements and ductwork configurations.


Tasks 2-9 will be common to each field test site and will be repeated for each
site that comes under a host site agreement.

Task 2 - Kick off Meeting Test Plan and Program Management Plan
---------------------------------------------------------------

The participant shall schedule and attend a kickoff meeting at each host site
with the appropriate plant, project, and environmental personnel. The
participant shall discuss the overall scope of the program, the potential impact
on plant equipment and operation and obtain information necessary to develop a
detailed test plan and program management plan. These documents shall be
available for host site personnel to use when addressing permitting, scheduling
and operating issues. The final test plan shall be completed 30 days prior to
testing and require concurrence from both the host site and DOE COR. The
participant shall also prepare a program management plan that includes
coordination, accounting, and project tracking activities for each host-site
field test.


<PAGE>


Task 3 - Sorbent Selection
--------------------------

The participant shall select at least two sorbents for evaluation during the
full-scale tests. These sorbents shall include at least one standard activated
carbon sorbent and one site-specific sorbent that demonstrates the best capacity
for mercury uptake based on mercury concentration, gas composition, temperature,
and mixing.

     Subtask 3.1 - Activated Carbon Screening:
     -----------------------------------------

     The participant shall characterize the physical and chemical properties of
     a given activated carbon followed by bench-scale, fixed-bed tests to
     determine the equilibrium absorption capacity and breakthrough
     characteristics. The sorbent shall be commercially available at a cost less
     than $.50/pound.

     Subtask 3.2- Site-Specific Sorbent Screening
     --------------------------------------------

     The participant shall evaluate the potential of alternate sorbents,
     including fly ash based products, to remove' mercury considering key
     factors such as carbon content, pore volume, surface area, and particle
     size distribution. The participant shall characterize the performance
     potential of candidate sorbents using equilibrium adsorption capacity data
     generated from fixed-bed, laboratory experiments with simulated flue gas.

All selected sorbents will be tested at the host site using a slipstream of gas
from full-scale systems. Additional site-specific sorbents shall also be tested
if the results from screening tests are promising and availability and cost are
reasonable. Samples of the candidate and selected sorbents shall be supplied to
DOE if requested by the COR.

Task 4 - Design and Fabrication of Site-Specific Equipment Needs
----------------------------------------------------------------

The participant shall insure the host utility obtains all permitting and
variance requirements. In test unit during sorbent injection. These components
shall be sized and designed for the specific plant arrangements and ductwork
configurations. Site specific equipment includes but is not limited to the
following:

The participant shall insure the host utility obtains all permitting and
variance requirements. In addition, the participant shall make arrangements with
the host utility to isolate fly ash from the test unit during sorbent injection.

Task 5 - Field Testing.
-----------------------

The field tests shall be accomplished through a series of nine (9) subtasks. The
subtasks shall be independent from each other in that each shall have specific
goals and tests associated with them. However, they shall also be interdependent
with the results from each task influencing the test parameters of subsequent
tasks.

     Subtask 5.1 - Pre-Baseline Measurements:
     ----------------------------------------

     The participant shall make preliminary system operation, performance and
     mercury level measurements prior to the start of equipment installation.
     The mercury shall be measured at both the inlet and outlet of the air
     pollution control device using a semi-continuous emissions (S-CEM) monitor
     for both total and speciated mercury concentrations. measurements shall be
     used to expedite the parametric evaluation, provide insight as to how
     mercury levels and removal efficiencies change in a transient and
     steady-state manner with varying boiler operation and to allow for the
     timely completion of the test plan. The participant shall verify the S-CEM
     by comparing its results to those obtained by Ontario-Hydro testing. During
     this period, the S-CEM shall be run continuously for a


<PAGE>


     minimum of 3 days. These data shall be used to understand the relationship
     between boiler operation (load and combustion conditions), control device
     inlet temperature, and fly ash properties (fly ash concentration and carbon
     content at the inlet and outlet of particulate matter control device and
     collection efficiency). The participant shall use these results in the
     design of parametric tests to reduce the number of uncontrolled variables.


     Subtask 5.2- Sorbent Screening:
     -------------------------------

     The participant. shall screen selected sorbents on actual flue gas prior to
     the start of equipment installation. The participant shall select the most
     promising sorbent/s based on these results and in coordination with Task 3.

     Subtask 5.3 - Site Modifications, Equipment Installation and System
     Checkout
     -------------------------------------------------------------------

     The participant shall oversee installation and checkout of the mercury
     control equipment. Procedures developed shall be similar to those used in
     the commercial installation of other flue gas conditioning systems. The
     participant shall work with the host utility to assure that the equipment
     is installed in an efficient manner, within the resources available at the
     site. In addition, the participant shall make arrangements with the host
     utility to isolate fly ash from the test unit during sorbent injection. The
     participant shall be responsible for final checkout of all systems and for
     the general maintenance of the systems during testing.

     Subtask 5.4 - Quality Assurance and Quality Control (QA/QC) Plan
     ----------------------------------------------------------------

     The participant shall prepare a QA/QC plan to control, evaluate, and
     document data quality to ensure that data generated are of the highest
     quality possible. The participant shall submit the QA/QC plan for DOE (and
     EPA if an agreement is negotiated between DOE and EPA) approval 30 days
     prior to each host-site field test. The plan shall be EPA ORD Level 2
     compliant and document that specific procedures that shall be adhered to
     and include data quality objectives and data quality indicator metrics to
     achieve them.



<PAGE>


The plan shall address:

     o QA/QC procedures associated with in sample collection, analytical and
     data analysis

          o    Integral performance evaluation and verification of Hg removal

          o    Data validation

          o    Data Treatment

          o    Procedural remedies for identified data deficiencies

     Other key questions the plan shall address include what will be done with
     the data, how will it be analyzed, will any duplicate (co-located) sampling
     take place, and what is the measurement precision. Table 1 summarizes
     several of the QA/QC activities DOE would like to consider. DOE reserves
     the right to coordinate with EPA to further refine required QA/QC
     activities.

     After equipment installation, the participant shall conduct a second,
     shorter set of baseline tests at conditions expected during the parametric
     tests. The participant shall ensure constant boiler load, standard soot
     blowing, and normal ESP rapping sequences or baghouse cleaning logic. The
     participant shall collect data during baseline operation that include the

     Subtask 5.6 - Parametric Test Series 1: Mercury Removal as a Function
     Temperature:
     ---------------------------------------------------------------------

     The participant shall conduct a series of tsts to determine the impace of
     inlet temperature on mercury removal efficiency across the particulate
     collection device. The participant shall define an operating window for
     temperature where maximum mercury removal can be obtained with a very low
     risk of duct deposition from spray cooling with water. The parametric tests



<PAGE>


     shall show the effects of boiler operating conditions and sorbent injection
     parameters .for temperatures less than 300(degree)F. Temperature shall be
     incrementally lowered to determine the effect of temperature and sorbent
     injection parameters on mercury removal and operational feasibility with
     the goal of obtaining maximum mercury removals. The participant shall pull
     the lances at least once per day during the tests to inspect for deposits
     forming around the nozzles and utilize an in-duct camera to monitor duct
     deposition.

     Subtask 5.7 - Parametric Test Series 2: Mercury Removal as a Function of
     Sorbent Injection:
     -------------------------------------------------------------------------

     The participant shall evaluate mercury removal as a function of sorbent
     injection rate at both the "normal" and optimized temperatures. The goal of
     this task shall be to define the quantity of sorbent required to obtain
     three different levels of mercury removal between 40% and 90% of the
     remaining mercury. The participant shall determine the optimum combination
     of cooling and sorbent injection required from subtask 5.6 data and input
     from available models. The optimum combination shall be based on a
     lowest-cost approach to a desired removal rate. The participant shall
     determine the operational time at each setting based on the time necessary
     to collect adequate operating/performance data. The participant shall
     utilize these results to determine the settings for the long-term test.
     These tests shall also be used to optimize performance and operation of the
     particulate control device. The participant shall provide additional
     flue-gas conditioning additives for particle resistivity and/or
     reentraimnent if required. DOE may provide (or coordinate with the prime
     participant) for additional sampling during the parametric testing.

DOE would primarily be concerned with co-pollutant control measurements of SO3,
HF, NOx, HCI, and fine particulate matter.

     Subtask 5.8 - Parametric Test Series 3: Mercury Removal as a Function of
     Alternate
     ---------------------------------------------------------------------------

     Sorbent Injection:
     ------------------

     The participant shall perform a set of parametric tests for evaluation of
     site-specific sorbent/s. These tests shall be conducted in a similar manner
     as those in subtask5. 7.

     Subtask 5.9 - Long-Term Testing:
     --------------------------------

     The participant shall perform mercury removal validation testing for a
     maximum of fourteen days at the "optimum" plant operating conditions
     (lowest cost/highest mercury removal) as determined from the parametric
     tests. The participant shall obtain DOE and host utility concurrence on the
     exact length of testing. The participant shall use commercially available
     semi-continuous mercury analyzers capable of measuring 0.1 microgram per
     normal cubic meter of mercury at the inlet of the particulate collector and
     at the outlet of the particulate collector during this test program to
     provide near real-time feedback. The participant shall calibrate the S-CEM
     every three days. The participant shall also make Ontario-Hydro
     measurements at the inlet and outlet of the particulate control device
     during testing. The participant shall strive for a leak-free sampling
     system. The participant shall place an oxygen analyzer downstream of the
     S-CEM to monitor and store the oxygen levels in the gas stream. The
     participant shall configure the gas sampling system in a manner to minimize
     any mercury removal or conversion due to the presence of particulate. The
     participant shall prepare a preliminary report on the removal efficiency
     over time, the effects on the particulate control device and balance of
     plant equipment, and on operation of the injection equipment to determine
     the viability and economics of the process.

     Task 6 - Data Analysis
     ----------------------

     The participant shall optimize data collection for the four host-sites
     measured and prepare a summary report on the effect of the combination of
     temperature and sorbent injection on mercury control and their impact on
     the existing pollution control equipment. The participant shall
     characterize mercury levels and plant operation for baseline conditions (no
     modification of


<PAGE>


     temperature or sorbent injection), various temperatures and injection rates
     as defined by the final test plan, and a long term evaluation to identify
     effects that may not be immediate. The participant shall collect samples of
     coal and fly ash during baseline testing for analysis. The participant
     shall conduct a full analysis of the coal including the mercury, chlorine
     and levels. The fly ash shall be analyzed for mercury and carbon content.
     Fly ash samples shall be collected from multiple locations when appropriate
     to determine if there is mercury segregation throughout the system or
     across the particulate collector. The participant shall conduct a full
     temperature, velocity and mercury (total and speciated) traverse at the
     inlet and outlet of the particulate collector during full-load conditions
     to determine profiles for appropriate sampling, humidification, and sorbent
     distribution. Following a complete mercury traverse using a S-CEM, the
     S-CEM shall be placed at the inlet to the particulate collector at a
     location identified from the traverse to represent the average duct
     concentration. While the first S-CEM is operating, a Second S~CEM shall be
     connected to the same probe to verify that both are measuring the same
     mercury concentration. The second S-CEM shall then be moved to the outlet
     of the particulate collector at a location identified from the traverse to
     indicate the duct average concentration. The participant shall obtain a
     triplicate manual mercury sample using the draft Ontario Hydro Method at
     the inlet location through a probe common to the inlet analyzer to verify
     operation of the analyzers. The participant shall monitor different plant
     signals to determine if any correlation exists between changes in mercury
     concentration and measured plant operating conditions.

     Task.7 - Waste Characterization
     -------------------------------

     The participant shall evaluate the stability and form of mercury in the ash
     for disposal and reuse (e.g. increased carbon content, elevated mercury
     concentrations). The participant shall utilize three series of standard
     procedures to assess the environmental stability of the ash and suitability
     for use in concrete. These tests consist of the Toxicity Characteristic
     Leaching Procedure (TCLP, SW846-1311 ), Specification C618 with air
     entrainment shaker tests, synthetic groundwater leaching procedure (SGLP),
     and thermal desorption (see Table 3). The participant


<PAGE>


     may perform additional tests on selected byproduct samples as needed to
     assess special. site- specific conditions that impact disposal or reuse
     options. The participant shall analyze selected samples of the fly ash for
     size, composition, and abundance of the ash particle types (for any host
     site that incorporates carbon separation). The participant shall obtain
     these grab samples of ash from control device hoppers during each day of
     testing. Samples shall be segregated by the test condition (baseline, each
     parametric test, and1ong-term test) and composited in 55-gallon drums with
     appropriate quantities placed into sample containers for shipping to the
     analytical laboratories. The participant! shall collect samples of the
     carbon-rich fraction in a similar manner as the ash samples for any host
     site that has a carbon separation process. Sampling and

     Task 8 - Design and Economics of Site-specific Control System

     After completion of testing and analysis of the data at each plant, the
     participant shall determine the requirements and costs for full-scale,
     permanent commercial implementation of the necessary equipment for mercury
     control using sorbent injection with humidification technology. The
     participant shall meet with the host utility plant and engineering
     personnel to develop plant specific design criteria. Process equipment
     shall be sized and designed based on test results and the plant specific
     requirements (reagent storage capacity, plant arrangement, retrofit issues,
     winterization, controls interface, etc.). A conceptual design document
     shall be developed with drawings and equipment lists. Modifications to
     existing plant equipment shall be determined and a work scope document
     developed based on input from the plant which may include modifications to
     the particulate collector, ash handling system, compressed air supply,
     electric power capacity, other plant auxiliary equipment, utilities and
     other balance of plant engineering

     removal, and a comparison of fly ash (with varying levels of unburned
     carbon) to activated carbon for mercury removal effectiveness. The
     participant shall also compare the database to EPRI's sorbent injection
     model which utilizes sorbent characteristics, mass transfer theory, and
     sorbent residence time in duct.


     Subtask 10.2 - Integrated Economic Analysis
     -------------------------------------------

     The participant shall determine the costs of controlling mercury emissions
     from coal- fired power plants I by conducting economic analyses on various
     mercury control technologies. After completion of all host-site testing,
     the participant shall submit a detailed economic analysis plan for DOE COR
     approval. This plan shall discuss the recommended economic methodology for
     evaluating electric utility industry costs as well as specific cost
     considerations and assumptions (including the requirements listed below).

     These economic/cost evaluations shall update and expand upon previous DOE
     cost assessments. The participant shall use the results from the host site
     tests in conjunction with detailed engineering cost estimates, reagent cost
     and transportation projections, impacts on downstream equipment, and O&M to
     determine full scale commercial costs for each fuel/plant/control
     configuration identified in Table 5.

requirements. Reagent type and sources shall be evaluated to determine the most
cost -effective reagent(s) for the site. Cost credits/penalties for fly ash
salability shall be estimated. The participant shall prepare a cost estimate to
implement the control technology. This shall include
capital cost estimates for mercury control process equipment as well as
projected annual operating costs. Where possible, order-of-magnitude estimates
will be included for plant modifications and balance of plant items.

Task 9 - Site Report
--------------------

The participant shall prepare a site report documenting all measurements, test
procedures, analyses, and results obtained in Tasks 2 through 8. This report
shall be a stand-alone document providing a comprehensive review of the testing
and data analyses completed at each host site.

Task 10 - Informaion Collection Request (ICR) Data Integration and Economic
Analysis
--------------------------------------------------------------------------------

This task consists of two sub tasks.

     Subtask 10.1 - ICR Data Integration
     -----------------------------------

     The participant shall prepare a database to catalog the level of mercury
     currently removed using ESP's and FF's without additional mercury controls.
     The participant shall populate this database with ICR Phase I, II, and III
     information showing plant configuration (boiler type, size, and emission
     control equipment, ESP or FF), fuel data (Btu, ash, sulfur, chlorine, and
     mercury), and mercury emission data (total and speciated) for the given
     load and temperature. The participant shall use the database to
     characterize the baseline ICR mercury removal as a function of fuel (type,
     chlorine content, etc.), configuration (ESP or FF), temperature and ash
     carbon content. The participant shall compare host sites' fly ash analyses
     (including mercury concentration and carbon content in fly ash) with any
     available plants' fly ash samples that were collected during ICR testing.
     The participant shall then integrate the host site field data with the
     database to identify any general trends. The participant shall specifically
     address mercury removal as a function of flue gas temperature, the effect
     of carbon content (native and re-injected) on mercury

     the appropriate literature, where details can be obtained. Equipment should
     be described only if it is not standard, or if information is not available
     thru the literature or other reference publications.

     RESULTS AND DISCUSSION* - It is extremely important that this section
     includes enough relevant data, especially statistical data, to allow the
     project manager to justify the conclusions. With the relevant data, explain
     how the data was interpreted and how it relates to the original purpose of
     the research. Be concise in the discussion on how this research effort
     solved or contributed to solving the original problem.


<PAGE>


     CONCLUSION* - The conclusion should not simply reiterate what was already
     included in the "Results and Discussion" section. It should, however,
     summarize what has already been presented, and include any logical
     implications of how the successes are relevant to technology development in
     the future. This is extremely important, since "relevancy" continues to be
     a criteria of the program.

4.10 ELECTRONIC MEDIA STANDARD FOR PREPARATION OF TECHNICAL REPORTS (DEC 1999)
--------------------------------------------------------------------------------

FILE FORMAT

     Production of high-quality, electronic documents is dependent on the
     quality of the input that is provided. Thus, the Recipient shall submit one
     good quality paper copy using either permanent or alkaline paper plus an
     electronic version of each technical report.


     ELECTRONIC REPORTS SHALL BE SUBMITTED IN THE ADOBE ACROBAT PORTABLE
     DOCUMENT FORMAT (PDF). ELECTRONIC REPORTS SUBMITTED IN A FORMAT OTHER THAN
     ADOBE WILL BE RETURNED AND THE REPORT CONSIDERED DELINQUENT.

     Each report shall be an integrated file that contains all text, tables,
     diagrams, photographs, schematics, graphs, and charts.

SUBMISSION FORMAT

     The electronic file(s} shall be submitted via diskette or CD-ROM. Diskettes
     or CD-ROMs must be labeled as follows:

        DOE Award Number
        Type/Frequency of Report(s)
        Reporting Period (if applicable)
        Name of submitting organization
        Name, phone number and fax number of preparer

     Diskettes -- Diskettes must be 3.5" double-sided, high-density (1.4 M Byte
     capacity). If file compression software is used to transmit a PDF file
     spanning more than one diskette, PKZIP from PKWare, Inc., is the required
     compression software. State the number of diskettes in the set (e.g.,



<PAGE>


     1/3)

     CD-ROM -- The electronic file(s) may be submitted on an ISO9660-format
     CD-ROM.

FILE NAMING

     In naming the electronic file, the Recipient shall use the standard
     eight-character naming convention for the main file name, and the three
     character extension applicable to the software use, e.g., .pdf for Adobe.

     For the main file name, .the first five characters are the last five digits
     from the award number; e.g., for Award Number DE-FG26-97NT12345, the first
     five characters are 12345.

     The next character represents the technical report and will always be
     designated as "R",

     The remaining two characters indicate the chronological number of the
     particular type of report; e.g., Quarterly Technical Progress Reports for a
     5-year award are numbered R01 through R20. Thus, the main file name for the
     sixth Quarterly Technical Progress Report under Award No. DE-FG26-
     99NT12345 would be 12345R06.PDF. If monthly, quarterly, annual, and a final
     technical report are required, the numbers would run from R01 through R86
     (60 monthly reports, 20 quarterly reports, 5 annual reports, and 1 final
     report).

4.11 ENVIRONMENTAL (DEC 1999)
-----------------------------

In response to the requirements of the National Environmental Policy Act of 1969
(NEPA) and other related environmental statutes, the National Energy Technology
Laboratory (NETL) requires the submission of various documents that assess the
environmental aspects and projected impacts of all of its proposed actions.
These documents may include the following: (1) Hazardous Substance Plan, (2)
Hazardous Waste Report, (3) Environmental Compliance Plan, (4) Environmental
Monitoring Plan, and (5) Environmental Status Reports.

The environmental information provided in these documents will enable NETL to
fulfill its responsibilities under NEPA (additional information about the
requirements of the National Environmental Policy Act can be found in the DOE
NEPA Compliance Guide and 10 CFR 1021) and to monitor the Recipient's compliance
with other environmental regulations. The implementation of any task associated
with a proposed action will be dependent upon DOE completing necessary NEPA
documentation. Therefore, to minimize the risk of project delays, it is
imperative that these reports be submitted in a timely manner.

The information contained herein specifies the basic environmental requirements
for this award, but it is not to be interpreted as containing all necessary
information for any given project. Likewise, certain aspects of the requirements
may not be applicable. Accordingly, the level of information provided should be
sufficient for DOE to assess the environmental implications of the proposed
action.

4.12 HAZARDOUS SUBSTANCE PLAN (MAY 1999)
----------------------------------------

The Recipient shall submit a Hazardous Substance Plan not later than thirty (30)
days after initial award. The Plan shall specifically identify each Hazardous
Substance (as defined under 40 CFR 261, Subpart D, entitled Lists of Hazardous
Wastes) anticipated to be purchased, utilized or generated in the performance of
this award. For each such Hazardous Substance identified, the Plan shall
specifically provide the following information:

     Description of Substance/Chemical
     EPA Hazardous Waste Number
     EPA Hazard Code
     Anticipated Quantity to be purchased, utilized or generated

     Anticipated Treatment Method

4.13 HAZARDOOUS WASTE REPORT (MAY 1999)
---------------------------------------

The Recipient shall submit a Hazardous Waste Report at the completion of award
performance. The Report shall specifically identify each Hazardous Waste (as
defined under 40 CFR 261, subpart d, entitled Lists of Hazardous Wastes)
actually utilized, or generated in the performance of this award. For each such
Hazardous Waste identified, the Report shall specifically provide the following
information:

     Description of substance/Chemical
     EPA Hazardous Waste Number
     EPA Hazard Code
     Actual Quantity Disposed
     Actual Hazardous Waste Transporter
     Actual Hazardous Waste Disposal Facility Contractor and Location
     (City/Municipality, State)
     Actual Disposal Date
     Actual Treatment Method

The Hazardous Waste Report is intended as a final reconciliation of anticipated
versus actual Hazardous Substances purchased, utilized, or generated in the
performance of this award.

4.14 PROPERTY REPORTS (DEC 1999)
--------------------------------

The NETL Property Handbook entitled "Management of Government Property in the
Possession of Contractors," contains forms, instructions, and suggested formats
for submission of property reports. This handbook can be found at

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

This report submitted on the SF-1428 and SF-120 is due immediately upon
completion or termination of the award. The Recipient is required to perform and
cause each subcontractor to perform a physical inventory, adequate for disposal
purposes, of all Government property applicable to the award.

4.16 REPORT OF TERMINATION OR COMPLETION INVENTORY (SF-1428 AND SF-120) (MAY
1999)
--------------------------------------------------------------------------------

The "Hot Line Report" may be used to report a major breakthrough in research,
development, or design; an event causing a significant schedule slippage or cost
growth; an environmental, safety and health violation; achievement of or failure
to achieve an important technical objective; or any requirement for quickly
documented direction or redirection. The report shall be submitted by the most
rapid means available, usually electronic, and should confirm telephone
conversations with DOE representatives. Identification as a "Hot Line Report"
serves notice at each link in the delivery chain that expedition in handling is
required. Unless otherwise agreed by the parties involved, DOE is expected to
take action and respond in a similarly timely manner. The report should include:

        1.  Recipient's name and address;
        2.  Award title and number;
        3.  Date;
        4.  Brief statement of problem or event;
        5.  Anticipated impacts; and
        6.  Corrective action taken or recommended.

Hot line reports shall document the incidents listed below:


<PAGE>


     1. Any single fatality or injuries requiring hospitalization of five or
     more individuals is to be immediately reported.

     2. Any significant environmental permit violation is to be reported as soon
     as possible, but within 24 hours of the discovery of the incident.

     3. Other incidents that have the potential for high visibility in the media
     are to be reported as quickly as possible, but within 24 hours following
     discovery.

     4. Any failure resulting in damage to Government-owned equipment in excess
     of $50,000 is to be reported as quickly as possible, but within 24 hours of
     the discovery of the failure.

     5. Any unplanned event which is anticipated to cause a schedule slippage or
     cost increase significant to the project is to be reported within 24 hours.

     6. Any verbal or written Notice of Violation of any Environmental, Safety,
     and Health statutes arising from the performance of this award is to be
     immediately reported.

     7. Any accidental spill or release which is in violation of any
     Environmental, Safety, and Health statutes arising from the performance of
     this award is to be immediately reported, but within 24 hours of the
     discovery of the accident.

     8. Any incident which causes a significant process or hazard control system
     failure, or is indicative of one which may lead to any of the above defined
     incidents, is to be reported as soon as possible, but within 5 days of
     discovery.

The requirement to submit Hot Line Reports for the incidents identified in 1, 2,
3, 6, or 7 is for the sole purpose of enabling DOE officials to respond to
questions relating to such events from the media and other public.

When an incident is reported in accordance with 4, 5, 6, 7, or 8, the Recipient
shall conduct an investigation of its cause and make an assessment of the
adequacy of resultant action. A written report is required no later than ten
(10) calendar days following the incident and shall include an analysis of the
pertinent facts regarding the cause, and a schedule of the remedial events and
time periods necessary to correct the action.

When an event results in the need to issue a written or verbal statement to the
local media, the statement is to be cleared first; if possible, and coordinated
with NETL Management and Communications Division, the Contracting Officer
Representative (COR) and the Contracting Officer.
