Due to automated procedures employed in formulating this document, clauses and
provisions within it may not always be continuously numbered.

2.2 PREVAILING REGULATIONS (NOV 1998)
-------------------------------------

As indicated on the face page, Block 18c, this Award is subject to the DOE
Assistance Regulations of Title 10, 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

2.3 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.

2.4 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.

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

          The Recipient shall be responsible for all aspects of project
          performance as set forth in the Application dated May 10,1999, 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 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
          to comment on those technical reports, plans, and other technical

                                        2
<PAGE>

          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 Parties
     -----------------------------------------

          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.

2.5 COST SHARING (DEC 1999)
---------------------------

In accordance with 10 CFR 600.1230), cost sharing by the Recipient is required
and is to be not less than 20% of the total proposed amount.

The total estimated project cost is $1,784,141. For billing purposes, DOE and
the Participant shall share actual allowable direct and indirect project costs
(including cost sharing) in the percentages set forth below:

DOE                73%
Participant        27%

If final allowable project costs exceed $1,297,351, DOE's maximum contribution
to the project is $1,033,956. Once DOE has paid $1,033,956, the Participant
shall complete the project at the Participant's own expense.

If final allowable costs are less than $1,297,351, and the Participant completes
the project, DOE shall share 80% of final allowable project costs.

2.6 FUNDING (JULY 1999)
-----------------------

Funding in the amount of $249,000 is obligated and made available for payment of
the Government's share of allowable costs.

The Recipient shall promptly notify the Contracting Officer in writing of the
estimated amount of additional funds, if any, are required to continue timely
performance under this award and when the funds will be required. The maximum
DOE obligation to the Recipient is shown in Block 16 of the DOE Form 4600.1. The
Government is not obligated to increase the total dollar amount funded and the
Recipient is not obligated to continue performance under this award or otherwise
incur costs to the extent that the Government's share of allowable costs would
exceed the amount obligated by the Government.

2.7 METHOD OF PAYMENT (DEC 1999)

detail to permit evaluation of the impact on the project. No key personnel may
be substituted without the Contracting Officer's approval. Such approval shall

2.16 PUBLIC ACCESS TO INFORMATION (JULY 1999)
---------------------------------------------

The Freedom of Information Act, as amended, and the DOE implementing regulations
(10 CFR 1004) require DOE to release certain documents and records regarding
awards to any person who provides a written request. The intended use of the
information will not be a criterion for release. These requirements apply to
information held by DOE and do not require Recipients, their subgrantees, or
their contractors to permit public access to their records.

2.17 NATIONAL SECURITY (NOV 1998)
---------------------------------

It is not expected that activities under the award will generate or otherwise
involve classified information (i.e. Restricted Data, Formerly Restricted Data,
National Security Information).

However, if in the opinion of the Recipient or DOE such involvement becomes
expected prior to the closeout of the award, the Recipient or DOE shall notify
the other in writing immediately. If the Recipient believes any information
developed or acquired may be classifiable, the Recipient shall not provide the
potentially classifiable information to anyone, including the DOE officials with
whom the Recipient normally communicates, except the Director of Classification,
and shall protect such information as if it were classified until notified by
DOE that a determination has been made that it does not require such handling.
Correspondence which includes the specific information in question shall be sent
by registered mail to U. S. Department of Energy, Attn.: Executive Assistant for
Defense Programs, DP-4, 4A-019/FORS, 1000 Independence Avenue, Washington, D.C.

the award by mutual agreement. If the award is to be terminated, all materials
deemed by DOE to be classified shall be forwarded to DOE, in a manner specified

                                       5
<PAGE>

by DOE, for proper disposition. If the Recipient and DOE wish to continue the
award, even though classified information is involved, the Recipient shall be
required to obtain both personnel and facility security clearances through the
Office of Safeguards and Security for Headquarters awarded awards obtained
through DOE field organizations. Costs associated with handling and protecting
any such classified information shall be negotiated at the time the
determination to proceed is made.

2.18 COMPLIANCE WITH BUY AMERICAN ACT (DEC 1999)
------------------------------------------------

In accepting this award, the Recipient agrees to comply with sections 2 through
4 of the Act of March 3, 1933 (41 U.S.C. 10a-10c, popularly known as the "Buy

addition to those prescribed elsewhere in statute and regulation.

A copy of the DOE "Lobbying Brochure" which provides a summary of the statutory
and regulatory restrictions regarding lobbying activities for Federal
contractors can be found at (http://www.Dr.doe.aov/lobbying.html).

2.21 NOTICE REGARDING UNALLOWABLE COSTS AND LOBBYING ACTIVITIES (NOV 1998)
--------------------------------------------------------------------------

Recipients of financial assistance are cautioned to carefully review the
allowable cost and other provisions applicable to expenditures under their
particular award instruments. If financial assistance funds are spent for
purposes or in amounts inconsistent with the allowable cost or any other
provisions governing expenditures in an award instrument, the government may
pursue a number of remedies against the Recipient, including in appropriate
circumstances, recovery of such funds, termination of the award, suspension or
debarment of the Recipient from future awards, and criminal prosecution for
false statements.

Particular care should be taken by the Recipient to comply with the provisions
prohibiting the expenditure of funds for lobbying and related activities.
Financial assistance awards may be used to describe and promote the
understanding of scientific and technical aspects of specific energy
technologies, but not to encourage or support political activities such as the
collection and dissemination of information related to potential, planned or
pending legislation.

2.22 YEAR 2000 COMPLIANCE (NOV 1998)
------------------------------------

Year 2000 compliant means, with respect to information technology, the
information technology accurately processes date/time data (including, but not
limited to, calculating, comparing, and sequencing) from, into, and between the
twentieth and twenty-first centuries, and the years 1999 and 2000 and leap year
calculations, to the extent that other information technology, used in
combination with the information technology being acquired, properly exchanges
date/time data with it.

The Recipient assures, by acceptance of this award, that items delivered under
this contract are year 2000 compliant.

2.23 REPORTING (NOV 1998)
-------------------------

Failure to comply with the reporting requirements contained in this award will
be considered a material noncompliance with the terms of the award.
Noncompliance may result in a withholding of future payments, suspension or
termination of the current award, and withholding of future awards. A willful
failure to perform, or of unsatisfactory performance of this and/or other
financial assistance awards, may also result in a debarment action to preclude
future awards by Federal agencies.

          the licensing of Government-owned inventions" mean the Department of
          Energy patent licensing regulations at 10 CFR Part 781.

     (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

                                       10

<PAGE>

          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.

          (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 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 at 952.227-13.

          (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 (j) 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

                                       12

<PAGE>

     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 U) of
     this clause. As required by 35 U.S.C. 202(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.

     (j) 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;

                                       13

<PAGE>

          (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 attract 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 bring 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).

     (I) Communications.

          (1) The contractor shall direct any notification, disclosure, or
          request to DOE provided for in this clause to the DOE patent counsel
          assisting the DOE contracting activity, with a copy of the
          communication to the Contracting Officer.

          (2) Each exercise of discretion or decision provided for in this
          clause, except subparagraph (k}(4). is reserved for the DOE Patent
          Counsel and is not a claim or dispute and is not subject to the
          Contract Disputes Act of 1978.

          (3) Upon request of the DOE Patent Counselor the contracting officer,
          the contractor shall provide any or all of the following:

               (i) a copy of the patent application, filing date, serial number
               and title, patent number, and issue date for any subject
               invention in any country in which the contractor has applied for
               a patent;

               (ii) a report, not more often than annually, summarizing all
               subject inventions which were disclosed to DOE individually
               during the reporting period specified; or

               (iii) a report, prior to closeout of the contract, listing all
               subject inventions or stating that there were none.

     Contractor, when requested, shall promptly deliver to Patent Counsel a duly
     executed and approved instrument fully confirmatory of all rights to which
     the Government is entitled.

(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.

3.11 RIGHTS IN TECHNICAL DATA
-----------------------------

A.   Withholding of limited rights data. Notwithstanding the inclusion of clause
     FAR 52.227-16, Additional Technical Data Requirements, in this Cooperative
     Agreement or any provision of this Cooperative Agreement specifying the
     delivery of technical data, the Participant may withhold limited rights
     data from delivery, provided that the Participant furnishes in lieu of any
     such limited rights data so withheld technical data disclosing the source,
     size, configuration, mating and attachment characteristics, functional

                                       19

<PAGE>

     characteristics, and performance requirements ("Form, Fit and Function"
     data, e.g., specification control drawing, catalog sheets, envelope
     drawings, etc.), or a general description of such limited rights data where
     "Form, Fit and Function" data are not applicable. Such data shall be
     subject to the provision of clause FAR 52.227-14, Rights in Data-- General
     with Alternative V, paragraph G), "Inspection rights," and paragraph (g),
     "Protection of limited rights data and restricted computer software.

     1.   The limited rights data subject to clause FAR 52.227-14 are described
          as follows: (1) "Chemical formulations of flue gas conditioning
          agents", and (2) "Lance and Injection System". This listing of data,
          which are asserted by the Participant to be limited rights data, does
          not constitute an admission by the Government that the data is in fact
          limited rights data.

          If a patent is issued by the United States Patent and Trademark Office
          (U.S. PTO) or the patent office of any foreign country based on any
          information asserted to be limited rights data, the Government will no
          longer treat any data contained in such issued patent as limited
          rights data. In addition, if any information asserted to be limited
          rights data results in or becomes a Subject Invention, as that term is
          defined in DEAR 952.227-11 (a), the Government will only treat such
          data as limited rights data until the Contractor has filed its initial
          patent application. Further, if the Government obtains title to the
          Subject Invention pursuant to DEAR 952.227-11 (d), the Government will
          no longer treat such data as limited rights data.

     2.   Subject to clause FAR 52.227-14 paragraph 0), any limited rights data
          specifically used in the performance of this Cooperative Agreement
          shall, at the option of the Contracting Officer, be available for
          inspection by a designee of the Contracting Officer at the project
          facility.

                               Statement of Work

     The overall objective of this program is to develop a family of cohesivity
modifying flue gas conditioning agents that can be commercialized to provide
utilities with a cost-effective means of complying with particulate emission and
opacity regulations. Improving the cohesivity and agglomeration of flyash
particles is a proven means of increasing the collection efficiency of an
electrostatic precipitator (ESP). Optimizing these properties is vital to the
overall collection efficiencies of ESPs, and flue gas conditioning may provide
the most cost effective means in today's deregulated utility market for plants
to meet DOE's goals of 0101 lb/MBtu and 99.99% collection efficiency in the
particle size 0.1 to 10 microns.

     This new class of additives is needed because currently available
agglomerating aids on the market require the storage and handling of large
quantities of ammonia, which under recent legislation has been classified as
extremely hazardous and necessitates extensive risk assessment and emergency
response plans. There are also operating conditions and coals where the ammonia
based technologies are not as effective and the treated ash treated is difficult
to dispose of because of the odor produced by ammonia.

Approach

     The primary objective will be achieved through a series of technical tasks
that begin in the laboratory, followed by a short "proof of concept"
demonstration at a utility plant, optimization of the conditioning technology
through the combination of laboratory and full scale evaluation and finally,
longer term demonstrations at various sites to prove the viability of the
technology over a broad range of applications. The successful completion of this
work requires both proper equipment and skills. ADA-ES has the majority of
laboratory and demonstration equipment in house and has a proven track record of
corporate experience dedicated to supporting technology development. The
technical tasks are summarized below.

                                                                               2

<PAGE>

Task 1. Upgrade Existing Laboratory Test Apparatus: Improve the capability of
existing equipment to directly measure cohesivity and tensile strength.

Task 2. Identify and Evaluate Candidate Cohesivity Enhancement Additives:
Perform screening tests to identify the most promising candidate additives,
followed by an intensive series of parametric tests to assure the additives meet
the requirement in terms of performance, ability to integrate easily with the
plant process and cost.

Task 3. Demonstrate Performance at Full Scale and Optimize Product: Prepare and
install equipment for the demonstration of the most promising additive or
additives on at least a portion of a full-scale ESP. This test will confirm
anticipated performance and identify properties that can not be simulated in
laboratory tests.

Task 4. Identify Potential Longer Term Demonstration Sites: To meet DOE's goal
that the newly developed technology be applicable for a variety of coals and
configurations, demonstrations will be conducted at several sites. In this task
additional test sites will be identified and contacted.

Task 5. Conduct Demonstrations to Confirm Performance for Different Coals and
Configurations: Additive performance will be evaluated at several different
sites. The coals will be representative of types widely used. The two primary
groups of interest are Powder River Basin Sub-bituminous and a low sulfur washed
eastern bituminous with ash silica-alumina content above 85%. Also of interest
is a site that fires a high sulfur bituminous coal with a scrubber-ESP
configuration.

                                                                               3

<PAGE>

Task 6. Determine Waste Characteristics: Determine the effect of the additive on
flyash disposal and reuse properties.

Task 7. Perform Economic Analysis: Develop the economics of the conditioning
technology following EPRI approved techniques, where costs are presented as
normalized busbar costs.

Task 8. Management and Reporting: Define project schedule, milestones and
costing for internal project tracking. Prepare and submit DOE required reports.

                                                                               4

          opinions of authors expressed herein do not necessarily state or
          reflect those of the United States Government or any agency thereof.

     " ABSTRACT* - should be a brief, concise summary of the report.

     TABLE OF CONTENTS*

     LIST(S) OF GRAPHICAL MATERIALS

     INTRODUCTION

     EXECUTIVE SUMMARY - this should be a well organized summary that highlights
     the important accomplishments of the research during the reporting period.
     It should be no less than one page and no more than two pages in length,
     and should be single spaced. This summary must be more comprehensive than
     the traditional "abstract."

<PAGE>

     EXPERIMENTAL * - this should describe, or reference all experimental
     methods being used for the research. It should also provide detail about
     materials and equipment being used. Standard methods can be referenced to
     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.

     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.

     REFERENCES*

     BIBLIOGRAPHY

     LIST OF ACRONYMS AND ABBREVIATIONS

     APPENDICES (IF NECESSARY)

Company Names and Logos - Except as indicated above, company names, logos, or

4.15 ELECTRONIC MEDIA STANDARD FOR PREPARATION OF TECHNICAL REPORTS (MAY 1999)
------------------------------------------------------------------------------

 FILE FORMAT

     Production of high-quality I 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

<PAGE>

     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., 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-FG26-00NT12345, 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- 00NT12345 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).

4.16 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.

and the DOE is under no commitment to provide additional funding to the
Recipient beyond this amount.

2.7  CONTINUATION APPLICATION (AUG 2001)

The Recipient will request advances using the ASAP payment system and will
request cash only as needed for immediate disbursements, will report cash
disbursements in a timely manner, and will impose the same standards of timing
and amount, including reporting requirements, on secondary recipients.

If DOE subsequently determines that the recipient's financial management system
does not meet the required standards of 10 CFR 600.121, or the recipient has not
maintained or demonstrated the willingness and ability to maintain written
procedures that minimize the time elapsing between the transfer of funds and
disbursement by the recipient, advance payments may be changed to payments by
reimbursement.

The Recipient is required to maintain advances of federal funds in interest
bearing accounts. Any interest income earned by the Recipient on federal funds
must be remitted at le ast quarterly to the cognizant DOE office. However, up to
$250 of the interest earned per year may be retained by the Recipient to cover
administrative expenses.

Funds advanced to the Recipient must be kept to a minimum amount necessary to
meet the Recipient's cash flow needs. Cash needs shall be determined by the
Recipient's cash outlay requirements and shall not be based on costs incurred.
If funds are erroneously drawn in excess of the Recipient's immediate
disbursement needs, the excess funds should be promptly refunded and reissued
when needed. The only exception to this is when excess funds will be disbursed
by the Recipient within seven calendar days or when the excess funds are less
than $10,000 and will be disbursed within thirty (30) calendar days.

          licensing of Government-owned inventions" mean the Department of
          Energy patent licensing regulations at 10 CFR Part 781.

(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 l-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)(l), (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 le arning 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.

     (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 shall instruct such

                                 ASSISTANCE AWARD                        9/27/02
================================================================================

     (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 at 952.227-13.

     (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 (j) 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. 202(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.

(j) 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
     attract 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 bring 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).

(l) Communications.

     (1) The contractor shall direct any notification, disclosure, or request to
     DOE provided for in this clause to the DOE patent counsel assisting the DOE
     contracting activity, with a copy of the communication to the Contracting
     Officer.

     (2) Each exercise of discretion or decision provided for in this clause,
     except subparagraph (k)(4), is reserved for the DOE Patent Counsel and is
     not a claim or dispute and is not subject to the Contract Disputes Act of
     1978.

     (3) Upon request of the DOE Patent Counsel or the contracting officer, the
     contractor shall provide any or all of the following:

          (i)  a copy of the patent application, filing date, serial number and
               title, patent number, and issue date for any subject invention in
               any country in which the contractor has applied for a patent;

          (ii) a report, not more often than annually, summarizing all subject
               inventions which were disclosed to DOE individually during the
               reporting period specified; or

          (iii) a report, prior to closeout of the contract, listing all subject
               inventions or stating that there were none.

(2) Data not first produced in the performance of this award. The Recipient
shall not, without prior written permission of the Contracting Officer,
incorporate in data delivered under this award any data not first produced in
the performance of this award and which contains the copyright notice of 17
U.S.C. 401 or 402, unless the Recipient identifies such data and grants to the
Government, or acquires on its behalf, a license of the same scope as set forth

unless otherwise specifically authorized in writing by the Contracting Officer.

(3) The Recipient agrees not to assert copyright in computer software first
produced in the performance of this award without prior written permission of
the DOE Patent Counsel assisting the contracting activity. When such permission

commercialization of the data. The Recipient, when requested, shall promptly
deliver to Patent Counsel a duly executed and approved instrument fully
confirmatory of all rights to which the Government is entitled.

(e) Unauthorized marking of data.

(1) Notwithstanding any other provisions of this award concerning inspection or
acceptance, if any data delivered under this award 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 award, the Contracting Officer may at
any time either return the data to the Recipient, 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 Recipient
affording the Recipient 30 days from receipt of the inquiry to provide written
justification to substantiate the propriety of the markings;

(ii) If the Recipient fails to respond or fails to provide written justification
to substantiate the propriety of the markings within the 30-day period (or a

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 Recipient 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 Recipient

concurrence of the head of the contracting activity, that the markings are not
authorized, the Contracting Officer shall furnish the Recipient a written

determination, which determination shall become the final agency decision
regarding the appropriateness of the markings unless the Recipient 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 award 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 Recipient is
not precluded by this paragraph (e) from bringing a claim under the Contract
Disputes Act, including pursuant to the Disputes clause of this award, as
applicable, that may arise as the result of the Government removing or ignoring
authorized markings on data delivered under this award.

(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 been disclosed without restriction outside the
Government, the Recipient may request, within 6 months (or a longer time
approved by the Contracting Officer for good cause shown) after delivery of such
data, permission to have notices placed on qualifying data at the Recipient's
expense, and the Contracting Officer may agree to do so if the Recipient -

(i) Identifies the data to which the omitted notice is to be applied;

(ii) Demonstrates that the omission of the notice was inadvertent;

(iii) Establishes that the use of the proposed notice is authorized; and

(iv) Acknowledges that the Government has no liability with respect to the
disclosure, use, or reproduction of any such data made prior to the addition of
the notice or resulting from the omission of the notice.

(2) The Contracting Officer may also (i) permit correction at the Recipient's
expense of incorrect notices if the Recipient identifies the data on which
correction of the notice is to be made, and demonstrates that the correct notice
is authorized, or (ii) correct any incorrect notices.

(g) Protection of limited rights data and restricted computer software.

(1) When data other than that listed in subdivisions (b)(1)(i), (ii), and (iii)
of this clause are specified to be delivered under this award and qualify as
either limited rights data or restricted computer software, if the Recipient
desires to continue protection of such data, the Recipient shall withhold such
data and not furnish them to the Government under this award. As a condition to
this withholding, the Recipient 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 database for delivery to the Government are to be
treated as limited rights data and not restricted computer software.

(h) Subcontracting. The Recipient has the responsibility to obtain from its
subcontractors all data and rights therein necessary to fulfill the Recipient's
obligations to the Government under this award. If a subcontractor refuses to
accept terms affording the Government such rights, the Recipient shall promptly
bring such refusal to the attention of the Contracting Officer and not proceed
with subcontract award without further authorization.

(i) Relationship to patents. Nothing contained in this clause shall imply a
license to the Government under any patent or be construed as affecting the
scope of any license or other right otherwise granted to the Government.

(j) The Recipient agrees, except as may be otherwise specified in this award for
specific data items listed as not subject to this paragraph, that the
Contracting Officer or an authorized representative may, up to three years after
acceptance of all items to be delivered under this award, inspect at the
Recipient's facility any data withheld pursuant to paragraph (g)(1) of this
clause, for purposes of verifying the Recipient's assertion pertaining to the
limited rights or restricted rights status of the data or for evaluating work
performance. Where the Recipient whose data are to be inspected demonstrates to
the Contracting Officer that there would be a possible conflict of interest if
the inspection were made by a particular representative, the Contracting Officer
shall designate an alternate inspector.

3.11 52.227-16 ADDITIONAL DATA REQUIREMENTS. (JUN 1987)

(a) In addition to the data (as defined in the clause at 52.227-14, Rights in
Data - General clause or other equivalent included in this contract) specified

of all items to be delivered under this contract, order any data first produced
or specifically used in the performance of this contract.

(b) The Rights in Data - General clause or other equivalent included in this
contract is applicable to all data ordered under this Additional Data
Requirements clause. Nothing contained in this clause shall require the
Contractor to deliver any data the withholding of which is authorized by the

whic h are specifically identified in this contract as not subject to this
clause.

(c) When data are to be delivered under this clause, the Contractor will be
compensated for converting the data into the prescribed form, for reproduction,
and for delivery.

(d) The Contracting Officer may release the Contractor from the requirements of
this clause for specifically identified data items at any time during the 3-year
period set forth in paragraph (a) of this clause.

3.12 52.227-23 RIGHTS TO PROPOSAL DATA (TECHNICAL). (JUN 1987)

Except for data contained on pages (n/a), it is agreed that as a condition of
award of this contract, and notwithstanding the conditions of any notice
appearing thereon, the Government shall have unlimited rights (as defined in the
"Rights in Data - General" clause contained in this contract) in and to the
technical data contained in the proposal dated 2-8-02, upon which this contract
is based.

4.2  ATTACHMENT A -- STATEMENT OF PROJECT OBJECTIVES (JAN 1999)

                   LONG TERM OPERATION OF A COHPAC SYSTEM FOR
                   REMOVING MERCURY FROM COAL-FIRED FLUE GAS

A.   OJECTIVES

The overall objective of this program is to evaluate the long term effects of
sorbent injection on mercury capture and COHPAC performance on 1/2 of the gas
stream at Alabama Power's Plant Gaston Unit 3. Data from the program will be
used to determine:

     1.   Is sorbent injection into a high air-to-cloth ratio baghouse a viable,
          long term approach for mercury control; and

     2.   Design criteria and costs for new baghouse/sorbent injection systems
          that will use a similar, polishing baghouse (TOXECON) approach.

B.   SCOPE OF WORK

Baghouse experts would agree that the only way to determine long term viability
of a new baghouse application is to review performance after a minimum of 6
months and preferable a year of operation. The technical approach proposed in
this effort is designed to gather both the necessary long-term data and to
investigate supporting technologies that might provide improved economics or
performance.

A commercial sorbent injection system will be procured that will allow for
continuous operation with minimal O&M requirements. COHPAC performance will be
evaluated using existing diagnostic equipment and with periodic, in-situ fabric
drag measurements. Mercury measurements will be made with a dedicated mercury
analyzer capable of measuring speciated, vapor phase mercury. Resources are set
aside to optimize operation of the mercury analyzers to minimize on-site
support. At a minimum, continuous mercury measurements will be made one week per
month and during certain test periods. To reduce risk to the host site, a new
set of bags will be purchased in case of irreparable degradation to the existing
bags. In addition, if new, high-performance fabrics are available, we will work
with EPRI and the developers to install and monitor limited numbers of these
bags. After performance is optimized with the benchmark sorbent, it will be
possible to perform short-term evaluations of up to 3 alternate sorbents.

C.   TASKS TO BE PERFORMED

The overall objective will be achieved through a series of technical tasks
described below.

Task 1.0 - Design, Procure and Install a Sorbent Injection System
-----------------------------------------------------------------

The deliverable for this first task is an installed and operational, commercial
quality dry sorbent injection system. ADA-ES will work with Norit Americas in
the design and procurement of the system. Norit Americas has an impressive
installation list for large activated carbon injection systems. Even so, these
systems are installed on processes that have much lower flue gas volumes than
most utility plants. ADA- ES will design and supply the injection manifolds and
lances.

Conceptually this injection system will include bulk storage for up to 1 1/2
trucks of carbon, sorbent delivery capability from pneumatic trucks, a
loss-of-weight balance for accurate tracking of carbon usage and Allen Bradley
PLC control and data acquisition capabilities. The system will be designed for
easy conversion to supply 100% of the Unit 3 flue gas, with the anticipation
that if the results are promising, the host site may want to continue use after
the end of the program.

ADA-ES will work with Alabama Power to select the installation contractor and
will oversee installation, shakedown and troubleshooting.

It is expected that this task will be completed 3 months after the contract is
awarded.

================================================================================

Task 2.0 - Procure Mercury Analyzer
-----------------------------------

One of the most difficult tasks of our current mercury control program is the
real time measurement of mercury. Apogee Scientific has provided excellent
support in this task by supplying the analyzers, analyzer operation, and data
acquisition and analysis.

The deliverable of this task is a mercury analyzer capable of speciated, vapor
phase mercury measurements with similar reliability to the instruments used in
the current program, but with reduced labor support requirements. ADA-ES will
continue to work with Apogee and apply their expertise to the procurement of the
best option and/or combinations of mercury measurement systems. If the state of
mercury measurement still has not improved past the need for a full-time person
to run the instruments, then the analyzer will be operated at least one week per
month and during optimization and subsystem testing.

Task 3.0 - System Optimization
------------------------------

The first month of operation will be devoted to integrating the injection and
mercury measurement systems with COHPAC and normal plant operation. It is
possible that injection concentration will change over time as pressure drop
performance is understood and as the performance of the upstream ESP varies.
Feedback control may be required in order to vary the injection concentration to
maintain the cleaning frequency below 1.5 pulses/bag/hour (practical limit
determined by Alabama Power during short-term tests).

New bags will not be installed for the beginning of these tests, as the current
bags are relatively new with less than 1 year of operating time. The first set
of Ryton bags installed in this COHPAC baghouse remained in service for over 4
years.

Also included in this task are baseline measurements of mercury and fabric drag.

Task 4.0 - Long Term Operation and Monitoring
---------------------------------------------

The primary subtasks include:

     1.   Integrating continuous injection of sorbent into the COHPAC baghouse
          through at least 3 seasons. This might seem like an odd way to track
          time, but experience has shown that particulate control equipment
          performs differently in the summer versus the winter months. Load
          capacity, ambient temperature, quality of the coal and, in this case,
          the performance cycle of the hot-side ESP affect COHPAC performance.
          Including optimization, the injection equipment will be available for
          operation over a 12-month period.

     2.   Tracking the pressure drop/cleaning frequency characteristics and
          strength integrity of the fabric. Operational trends will be monitored
          using the existing system supplied by Southern Research Institute.
          Performance variables that will be monitored continuously include
          pressure drop, cleaning frequency, inlet grain loading, flow, and
          outlet opacity.

          At least 24 new, standard bags will be installed prior to beginning
          carbon injection for control purposes. In-situ drag (drag = pressure
          drop divided by air-to-cloth ratio) measurements will be made on
          select bags to determine baseline drag conditions. Either the EPRI
          portable drag tester now at TXU's Big Brown station or Southern
          Research's device will be used. The drag of the selected bags will be
          measured periodically throughout the 12-month test period to track any
          increase in drag or decreases in permeability of the fabric. Drag
          tests will also be performed on bags in the control baghouse, A-side.

     3.   Periodic collection of coal and ash samples. Analyses will include
          ultimate and proximate, mercury and chlorine measurements of the coal,
          and mercury and LOI measurements of the ash. These samples will be
          archived and the final test samples will be determined based on
          mercury removal performance and test conditions. Daily coal samples
          will be taken during Ontario Hydro testing.

     4.   Measuring mercury following the draft Ontario Hydro method twice
          during the long term tests. The conditions for these tests will be
          decided after review of the results.

Charles Lindsey, with ADA-ES, lives in the Birmingham, Alabama area. Mr. Lindsey
will be available, if needed, for nearly full-time support of this test program.
ADA-ES will be responsible for operation of the mercury analyzers, teaching
Gaston personnel the operation of the injection system, ordering activated
carbon and coordinating all on-site tests. ADA-ES will work with Southern
Research Institute in the performance monitoring of COHPAC.

Task 5.0 - Subsystem Testing
----------------------------

This long-term test at Gaston provides an opportunity to evaluate other mercury
control sorbents that may have advantages in cost and/or performance, and
advanced fabrics that may enhance mercury control or COHPAC performance. Also
included in this task is the procurement of a repla cement set of PPS
(polyphenylene sulfide) felt bags for the B-side baghouse.

Several sorbent suppliers have asked to be contacted if additional baghouse test
time is available. The commercial suppliers include STI, Sorbtech, CarboChem and
Donau Carbon. In addition, EPRI has ongoing programs that both develop and
evaluate new sorbents. One or more of these sorbents may be of interest to the
test team.

The test plan has time set aside to evaluate three different sorbents. Each of
the alternative sorbents can be evaluated for up to two weeks, with the caveat
that tests will be ended early if any detrimental performance trends are noted.
During these test periods, the S-CEMs will be operational, ash and coal samples
will be collected, and COHPAC performance will be closely monitored.

The alternate suppliers will be asked to provide about 10,000 lbs of sorbent
delivered in a pneumatic truck with compatible hose connections. Shorter tests
can be considered, however, the injection system will not be able to accommodate
supersack deliveries. Results from these short tests will be compiled in an
informal report for the supplier.

A brief history of the PPS felt used in the COHPAC baghouse is needed to
understand the importance of potential alternate fabric tests. The OEM fabric
for the four COHPAC baghouses in the U.S. (Gaston Units 2 and 3 and Big Brown
Units 1 and 2) was a 2.7 denier RytonTM felt. Denier is a measure of the linear
density of a fiber and provides an indication of the cross section or thickness
of the fibers, and Ryton was the original PPS fiber. It took several years to
optimize the fabric specification for the Ryton bags at Big Brown, the first
COHPAC installation. Last year the producer of Ryton fabric stopped production
of the material. A direct, but unproven replacement PPS fiber is now provided by
Toray Industries and in know as Torcon.

EPRI has invested significant resources to develop a fabric that had inherently
higher permeability and therefore lower pressure drop. The most tested
high-permeability fabric was a 6 denier instead of 2.7 denier Ryton felt. The
test results after a year of operation at Big Brown showed the residual drag of
the 6 denier fabric was half that of the 2.7 denier fabric. This fabric helps
reduce pressure drop problems at Big Brown and the plant had switched to
ordering 6 denier fabric for all bag replacements. With Ryton no longer
available, the new high permeability fabric is 7 denier Torcon. This fabric has
just been installed in the full-scale units at Big Brown to begin a long-term
evaluation process.

================================================================================

This same fabric is of interest at Gaston because the major impact on COHPAC
from earlier short-term sorbent injection testing was an increase in cleaning
frequency, or equivalently pressure drop. This highpermeability fabric may
reduce the impact of the increased mass loading on pressure drop and allow for
either higher injection rates or less performance degradation over time. Because
of these ongoing developments in the design of the PPS felts, it is important to
include resources to install small numbers of test bags to begin gathering the
long-term data necessary to qualify the viability of the new fabric. Because
these test bags will be mixed with existing bags, outlet emissions or real time
pressure drop behavior can't be tracked. However, based on the work at Big Brown
it is possible to evaluate performance by periodically measure in-situ drag
(Bustard, et al., 2001).

Task 6.0 - Management and Reporting
-----------------------------------

A final report will be prepared documenting measurements, test procedures and
results obtained in Tasks 1 through 5. This report is intended to be a
stand-alone document providing a comprehensive review of the testing. This
report will also include an economic analysis of the cost of controlling mercury
emissions with sorbent injection.

This task also provides time for overall program management, technology transfer
and time to complete DOE's reporting requirements.

================================================================================

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., 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).

4.13 ENVIRONMENTAL (OCT 2000)

In response, in part, 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 MonitoringPlan, 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.
