            allowable and allocable costs of performance of the work on a 46.7

            Financial Assistance Award face page.

            The Government's share obligated in this agreement, in the amount of
            $1,425,057.00, is subject to the following conditions and
            limitations:

            a.    Funds in the amount of $1,425,057.00 are provided for the
                  reimbursement of the Government's share of costs associated

            b.    The parties have 120 days to complete negotiations of the

                  agree, that the allowable and allocable costs incurred, under
                  this cooperative agreement, shall be reimbursed on a 46.7
                  percent (Government) and 53.3 percent (Participant).

      $1,425,057.00 and no additional Federal funding will be provided
      notwithstanding the total cost of the project at completion.

2.    FEE

      No fee shall be paid to the Recipient or any subaward for performance
      under this Agreement.

3.    STATEMENT OF SUBSTATIAL INVOLVEMENT

      The Department of Energy (Department, DOE) will be substantially involved
      in all Tasks of the Statement of Work. The Department will collaborate
      with the participant in evaluating, accepting, and achieving the
      milestones for research as proposed by the respondent.

      The Department will provide technical direction to the overall program, as
      well as the individual program elements as it is determined to be
      necessary and appropriate by DOE. The Department will participate during
      the full duration of the project, and will have continuing rights to
      conduct ongoing negotiations with the participant regarding the technical
      direction of the work conducted under this Agreement. The Department staff
      members will attend meetings and participate in the formation and
      direction of scope of the key development activities. The DOE Project
      Officer will participate in the development, review and approval of all
      proposed statements of work, including subcontractor statements of work,
      prior to the execution of any subcontract. The Department will review
      technical progress reports and provide input to these reports as deemed
      necessary. In addition, the Department will have the right to have
      National Laboratories or selected private organizations perform
      independent tests and evaluations of the cooperative agreement's
      deliverables, thus providing an additional measure of technical progress.


                                       1
<PAGE>

      The Department may collaborate with the participant in the allocation of
      funds budgeted for this Agreement. Further, as work progresses, funding
      needs may change and depending upon availability of funds, the Department
      may collaborate with the participant to reallocate funds budgeted between
      the different programs and projects.

      The Department will thus be actively monitoring all phases of the
      participant's research and development activities, including participation
      in the participant's reviews of its contractor's activities and review of
      the contractor's reports to the participant. The Department will actively
      participate in the participant's process of reviewing and approving each
      phase of the proposed programs and projects.

      The substantial involvement by the Department under this Agreement will
      remain in effect for the term of the cooperative agreement award unless
      otherwise amended in writing by the Contracting Officer. Moreover, this
      statement of substantial involvement by the Department does not increase
      the Department of Energy's liability under the Agreement award.

4.    TECHNICAL DIRECTION

      A.    The work to be performed by the Participant under this Cooperative
            Agreement is subject to the surveillance and written Technical
            Direction of a "DOE Project Officer," identified in block 11 of the
            face page. The term "Technical Direction" is defined to include,
            without limitation, the following:

            1.    Directions to the Participant which redirects the work effort,
                  shifts work emphasis between work areas or tasks, require
                  pursuit of certain lines of inquiry, fill in details or
                  otherwise provide technical guidance to the Participant in
                  order to accomplish the tasks and requirements stated in the
                  Statement of Work as contained in the agreement.

            2.    Provision of information to the Participant which assists in
                  the interpretation of drawings, specifications or technical
                  portions of the Statement of Work as contained in the
                  Agreement.

            3.    Review and, where required by the Cooperative Agreement,
                  approval of technical reports, drawings, specifications or
                  technical information to be delivered by the Participant to
                  DOE under the Cooperative Agreement.

            4.    The DOE Project Officer shall monitor the Participant's
                  performance with respect to compliance with the requirements
                  of this Cooperative Agreement.

      B.    Technical direction and management surveillance shall not impose
            tasks or requirements upon the Participant additional to or
            different from the tasks and requirements stated in the Statement of
            Work of this Agreement. The Technical Direction to be valid:

            1.    Must be issued in writing consistent with the tasks and
                  requirements stated in the Statement of Work of this

                                       2
<PAGE>

            2.    May not:

                  a.    constitute an assignment of additional work outside the
                        tasks and requirements stated in the Statement of Work
                        of this Agreement;

                  b.    in any manner cause an increase or decrease in the total
                        estimated project cost or the time required for project
                        performance;

                  c.    change any of the expressed terms, conditions or
                        specification of the Cooperative Agreement; or

                  d.    accept non-conforming work.

      C.    The Participant shall proceed promptly with the performance of
            Technical Directions duly issued by the DOE Project Officer in the
            manner prescribed by paragraph B. above and which are within his
            authority under the provisions of paragraph A. above; provided,
            however, that the Participant shall immediately cease the
            performance of any Technical Direction upon receipt of a written
            instruction to that effect from the Contracting Officer.

      D.    If in the opinion of the Participant any Technical Direction issued
            by the DOE Project Officer is within one of the categories as
            defined in B.2b. (a) through (d) above, the Participant shall not
            proceed but shall notify the Contracting Officer in writing within
            five working days after the receipt of any such Technical Direction
            and shall request the Contracting Officer to rescind such direction
            or mutually agree to modify the agreement accordingly.

      E.    The only persons authorized to give Technical Direction to the
            Participant under this Agreement are the Contracting Officer and any
            "DOE Project Officer" as listed in Block 11 of the face page. Any
            action taken by the Participant in response to any direction given
            by any person other than the Contracting Officer or DOE Project
            Officer shall not be binding upon the Government.

5.    CONTINUATION OF WORK

      There will be an evaluation of the progress near the end of the project
      period to determine to either continue, redirect, or terminate the
      project.

      (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 subparagraphs (g)(2) or (g)(3) below 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
not 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
(i) above, the Contracting Officer shall consider such written justification and
determine whether or not the markings are to be canceled or ignore. 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 (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 (1) above
may be modified in accordance with agency regulations implementing the Freedom
of Information Act (5 U.S.C. 552) if necessary to respond to a request
thereunder.
      (3) This paragraph (e) does not apply if this contract is for a major
system or for support of a major system by a civilian agency other than NASA and
the U.S. Coast Guard subject to the provisions of Title III of the Federal
Property and Administrative Services Act of 1949.
      (4) Except to the extent the Government's action occurs as the result of
final disposition of the matter by a court of competent jurisdiction, the
Contractor is not precluded by this paragraph (e) from bringing a claim under
the Contract Disputes Act, including pursuant to the Disputes clause of this
contract, as applicable, that may arise as the result of the Government removing
or ignoring authorized markings on data delivered under this contract.


                                        3
<PAGE>

(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) below, or the copyright
notice required by paragraph (c) above, shall be deemed to have been furnished
with unlimited rights, and the Government assumes no liability for disclosure,
use, or reproduction of such data. However, to the extent the data has not been
disclosed without restriction outside the Government, the Contractor 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 Contractor's expense, and the Contracting
Officer may agree to do so if the Contractor:
            (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
Contractor's expense of incorrect notices if the Contractor 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 subparagraphs (b)(1)(i), (ii), and
(iii) above are specified to be delivered under this contract and qualify as
either limited rights data or restricted computer software, if the Contractor
desires to continue protection of such data, the Contractor shall withhold such
data and not furnish them to the Government under this Contract. As a condition
to this withholding, the Contractor shall identify the data being withheld and
furnish form, fit, and function data in lieu thereof. Limited rights data that
are formatted as a computer data base for delivery to the Government is to be
treated as limited rights data and not restricted computer software.

      (2) [Reserved.]

      (3) [Reserved.]

(h)   Subcontracting.
      The Contractor has the responsibility to obtain from its subcontractors
all data and rights therein necessary to fulfill the Contractor's obligations to
the Government under this contract. If a subcontractor refuses to accept terms
affording the Government such rights, the Contractor 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 Contractor agrees, except as may be otherwise specified in this
contract 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 contract, inspect at
the Contractor's facility any data withheld pursuant to paragraph (g)(1) above,
for purposes of verifying the Contractor's assertion pertaining to the limited

      REFUND OF ROYALTIES (FEB 1995)

(a) The contract price includes certain amounts for royalties payable by the
Contractor or subcontractors or both, which amounts have been reported to the
Contracting Officer.

(b) The term "royalties" as used in this clause refers to any costs or charges
in the nature of royalties, license fees, patent or license amortization costs,
or the like, for the use of or for rights in patents and patent applications in
connection with performing this contract or any subcontract here-under. The term
also includes any costs or charges associated with the access to, use of, or
other right pertaining to data that is represented to be proprietary and is
related to the performance of this contract or the copying of such data or data
that is copyrighted.

(c) The Contractor shall furnish to the Contracting Officer, before final
payment under this contract, a statement of royalties paid or required to be
paid in connection with performing this contract and subcontracts hereunder
together with the reasons.

(d) The Contractor will be compensated for royalties reported under paragraph
(c) of this clause, only to the extent that such royalties were included in the
contract price and are determined by the Contracting Officer to be properly
chargeable to the Government and allocable to the contract. To the extent that
any royalties that are included in the contract price are not, in fact, paid by
the Contractor or are determined by the Contracting Officer not to be properly
chargeable to the government and allocable to the contract, the contract price
shall be reduced. Repayment or credit to the Government shall be made as the
Contracting Officer directs. The approval by DOE of any individual payments or
royalties shall not prevent the Government from contesting at any time the
enforceability, validity, scope of, or title to, any patent or the proprietary
nature of data pursuant to which a royalty or other payment is to be or has been
made.

(e) If, at any time within 3 years after final payment under this contract, the
Contractor for any reason is relieved in whole or in part from the payment of
the royalties included in the final contract price as adjusted pursuant to
paragraph (d) of this clause, the Contractor shall promptly notify the
Contracting Officer of that fact and shall reimburse the Government in a
corresponding amount.

(f) The substance of this clause, including this paragraph (f), shall be
included in any subcontract in which the amount of royalties reported during
negotiation of the subcontract exceeds $250.

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 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
1-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 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


                                        8
<PAGE>

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."


                                        9
<PAGE>

(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;


                                       10
<PAGE>

      (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.

(End of clause)

the Contractor, may request greater rights than the nonexclusive license and the
foreign patent rights provided in paragraph (d) of this clause on identified
inventions in accordance with the DOE patent waiver regulations. A request for a
determination of whether the Contractor or the employee-inventor is entitled to
acquire such greater rights must be submitted to the Patent Counsel with a copy
to the Contracting Officer at the time of the first disclosure of the invention
pursuant to subparagraph (e)(2) of this clause, or not later than 8 months
thereafter, unless a longer period is authorized in writing by the Contracting
Officer for good cause shown in writing by the Contractor. Each determination of
greater rights under this contract shall be subject to paragraph (c) of this
clause, unless otherwise provided in the greater rights determination, and to
the reservations and conditions deemed to be appropriate by the Secretary of
Energy or designee.

            (ii) Within two (2) months after the filing of a patent application,
the Contractor shall provide the filing date, serial number and title, a copy of
the patent application (including an English-language version if filed in a
language other than English), and, promptly upon issuance of a patent, provide
the patent number and issue date for any subject invention in any country for
which the Contractor has been granted title or the right to file and prosecute
on behalf of the United States by the Department of Energy.

            (iii) Not less than thirty (30) days before the expiration of the
response period for any action required by the Patent and Trademark Office,
notify the Patent Counsel of any decision not to continue prosecution of the
application.

            (iv) Upon request, the Contractor shall furnish the Government an
irrevocable power to inspect and make copies of the patent application file.

(c) Minimum rights acquired by the Government.

      (1) With respect to each subject invention to which the Department of
Energy grants the Contractor principal or exclusive rights, the Contractor
agrees as follows:

            (i) The Contractor hereby grants to the Government a nonexclusive,
nontransferable, irrevocable, paid-up license to practice or have practiced each
subject invention throughout the world by or on behalf of the Government of the
United States (including any Government agency).

            (ii) The Contractor agrees that with respect to any subject
invention in which DOE has granted it title, DOE has the right in accordance
with the procedures in the DOE patent waiver regulations (10 CFR part 784) 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 it determines that--

                  (A) 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;

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

                  (C) 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

                  (D) Such action is necessary because the agreement required by
paragraph (i) of this clause has neither been obtained nor 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.

            (iii) 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 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 proceedings undertaken
by that agency in accordance with subparagraph (c)(1)(ii) of this clause. To the
extent data or information supplied under this section is considered by the
Contractor, its licensee, or assignee to be privileged and confidential and is
so marked, the Department of Energy agrees that, to the extent permitted by law,
it will not disclose such information to persons outside the Government.

            (iv) The Contractor agrees, when licensing a subject invention, to
arrange to avoid royalty charges on acquisitions involving Government funds,
including funds derived through a Military Assistance Program of the Government
or otherwise derived through the Government, to refund any amounts received as
royalty charges on a subject invention in acquisitions for, or on behalf of, the
Government, and to provide for such refund in any instrument transferring rights
in the invention to any party.

            (v) The Contractor agrees to provide for the Government's paid-up
license pursuant to subparagraph (c)(1)(i) of this clause in any instrument
transferring rights in a subject invention and to provide for the granting of
licenses as required by subparagraph (c)(1)(ii) of this clause, and for the
reporting of utilization information as required by subparagraph (c)(1)(iii) of
this clause, whenever the instrument transfers principal or exclusive rights in
a subject invention.

      (2) Nothing contained in this paragraph (c) shall be deemed to grant to
the Government any rights with respect to any invention other than a subject
invention.

(d) Minimum rights to the Contractor.


                                       13
<PAGE>

      (1) The Contractor is hereby granted a revocable, nonexclusive,
royalty-free license in each patent application filed in any country on a
subject invention and any resulting patent in which the Government obtains
title, unless the Contractor fails to disclose the subject invention within the
times specified in subparagraph (e)(2) of this clause. The Contractors license
extends to its domestic subsidiaries and affiliates, if any, within the
corporate structure of which the Contractor is a part 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 DOE 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 the subject
invention pursuant to an application for an exclusive license submitted in
accordance with applicable provisions in 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 applications
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 its 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 agency licensing regulations
and 37 CFR Part 404 concerning the licensing of Government-owned inventions, any
decision concerning the revocation or modification of its license.

      (4) The Contractor may request the right to acquire patent rights to a
subject invention in any foreign country where the Government has elected not to
secure such rights, subject to the conditions in subparagraphs (d)(4)(i) through
(d)(4)(vii) of this clause. Such request must be made in writing to the Patent
Counsel as part of the disclosure required by subparagraph (e)(2) of this
clause, with a copy to the DOE Contracting Officer. DOE approval, if given, will
be based on a determination that this would best serve the national interest.

            (i) The recipient of such rights, when specifically requested by
DOE, and three years after issuance of a foreign patent disclosing the subject
invention, shall furnish DOE a report stating:

                  (A) The commercial use that is being made, or is intended to
be made, of said invention, and

                  (B) The steps taken to bring the invention to the point of
practical application or to make the invention available for licensing.

            (ii) The Government shall retain at least an irrevocable,
nonexclusive, paid-up license to make, use, and sell the invention throughout
the world by or on behalf of the Government (including any Government agency)
and States and domestic municipal governments, unless the Secretary of Energy or
designee determines that it would not be in the public interest to acquire the
license for the States and domestic municipal governments.

            (iii) If noted elsewhere in this contract as a condition of the
grant of an advance waiver of the Government's title to inventions under this
contract, or, if no advance waiver was granted but a waiver of the Government's
title to an identified invention is granted pursuant to subparagraph (d)(2) of
this clause upon a determination by the Secretary of Energy that it is in the
Government's best interest, this license shall include the right of the
Government to sublicense foreign governments pursuant to any existing or future
treaty or agreement with such foreign governments.

            (iv) Subject to the rights granted in subparagraphs (d)(1), (2), and
(3) of this clause, the Secretary of Energy or designee shall have the right to
terminate the foreign patent rights granted in this subparagraph (d)(4) in whole
or in part unless the recipient of such rights demonstrates to the satisfaction
of the Secretary of Energy or designee that effective steps necessary to
accomplish substantial utilization of the invention have been taken or within a
reasonable time will be taken.

            (v) Subject to the rights granted in subparagraphs (d)(1), (2), and
(3) of this clause, the Secretary of Energy or designee shall have the right,
commencing four years after foreign patent rights are accorded under


                                       14
<PAGE>

this subparagraph (d)(4), to require the granting of a nonexclusive or partially
exclusive license to a responsible applicant or applicants, upon terms
reasonable under the circumstances, and in appropriate circumstances to
terminate said foreign patent rights in whole or in part, following a hearing
upon notice thereof to the public, upon a petition by an interested person
justifying such hearing:

                  (A) If the Secretary of Energy or designee determines, upon
review of such material as he deems relevant, and after the recipient of such
rights or other interested person has had the opportunity to provide such
relevant and material information as the Secretary or designee may require, that
such foreign patent rights have tended substantially to lessen competition or to
result in undue market concentration in any section of the United States in any
line of commerce to which the technology relates; or

                  (B) Unless the recipient of such rights demonstrates to the
satisfaction of the Secretary of Energy or designee at such hearing that the
recipient has taken effective steps, or within a reasonable time thereafter is
expected to take such steps, necessary to accomplish substantial utilization of
the invention.

            (vi) If the contractor is to file a foreign patent application on a
subject invention, the Government agrees, upon written request, to use its best
efforts to withhold publication of such invention disclosures for such period of
time as specified by Patent Counsel, but in no event shall the Government or its
employees be liable for any publication thereof.

            (vii) Subject to the license specified in subparagraphs (d)(1), (2),
and (3) of this clause, the contractor or inventor agrees to convey to the
Government, upon request, the entire right, title, and interest in any foreign
country in which the contractor or inventor fails to have a patent application
filed in a timely manner or decides not to continue prosecution or to pay any
maintenance fees covering the invention. To avoid forfeiture of the patent
application or patent, the contractor or inventor shall, not less than 60 days
before the expiration period for any action required by any patent office,
notify the Patent Counsel of such failure or decision, and deliver to the Patent
Counsel, the executed instruments necessary for the conveyance specified in this
paragraph.

(e) Invention identification, disclosures, and reports.

      (1) The Contractor shall establish and maintain active and effective
procedures to assure that subject inventions are promptly identified and
disclosed o Contractor personnel responsible for patent matters within 6 months
of conception and/or first actual reduction to practice, whichever occurs first
in the performance of work under this contract. These procedures shall include
the maintenance of laboratory notebooks or equivalent records and other records
as are reasonably necessary to document the conception and/or the first actual
reduction to practice of subject inventions, and records that show that the
procedures for identifying and disclosing the inventions are followed. Upon
request, the Contractor shall furnish the Contracting Officer a description of
such procedures for evaluation and for determination as to their effectiveness.

      (2) The Contractor shall disclose each subject invention to the DOE Patent
Counsel with a copy to the Contracting Officer within 2 months after the
inventor discloses it in writing to Contractor personnel responsible for patent
matters or, if earlier, within 6 months after the Contractor becomes aware that
a subject invention has been made, but in any event before any on sale, public
use, or publication of such invention known to the Contractor. 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
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 DOE, the
Contractor shall promptly notify Patent Counsel of the acceptance of any
manuscript describing the invention for publication or of any on sale or public
use planned by the Contractor. The report should also include any request for a
greater rights determination in accordance with subparagraph (b)(2) of this
clause. When an invention is disclosed to DOE under this paragraph, it shall be
deemed to have been made in the manner specified in Sections (a)(1) and (a)(2)
of 42 U.S.C. 5908, unless the Contractor contends in writing at the time the
invention is disclosed that is was not so made.

      (3) The Contractor shall furnish the Contracting Officer the following:


                                       15
<PAGE>

            (i) Interim reports every 12 months (or such longer period as may be
specified by the Contracting Officer) from the date of the contract, listing
subject inventions during that period, and certifying that all subject
inventions have been disclosed (or that there are not such inventions) and that
the procedures required by subparagraph (e)(1) of this clause have been
followed.

            (ii) A final report, within 3 months after completion of the
contracted work listing all subject inventions or certifying that there were no
such inventions, and listing all subcontracts at any tier containing a patent
rights clause or certifying that there were no such subcontracts.

      (4) 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 (e)(2) of this clause.

      (5) The Contractor agrees, subject to FAR 27.302(j), that the Government
may duplicate and disclose subject invention disclosures and all other reports
and papers furnished or required to be furnished pursuant to this clause.

(f) Examination of records relating to inventions.

      (1) The Contracting Officer or any authorized representative shall, until
3 years after final payment under this contract, have the right to examine any
books (including laboratory notebooks), records, and documents of the Contractor
relating to the conception or first actual reduction to practice of inventions
in the same field of technology as the work under this contract to determine
whether--

            (i) Any such inventions are subject inventions;

            (ii) The Contractor has established and maintains the procedures
required by subparagraphs (e)(1) and (4) of this clause;

            (iii) The Contractor and its inventors have complied with the
procedures.

      (2) If the Contracting Officer learns of an unreported Contractor
invention which the Contracting Officer believes may be a subject invention, the
Contractor may be required to disclose the invention to DOE for a determination
of ownership rights.

      (3) Any examination of records under this paragraph will be subject to
appropriate conditions to protect the confidentiality of the information
involved.

(g) Withholding of payment (NOTE: This paragraph does not apply to
subcontracts).

      (1) Any time before final payment under this contract, the Contracting
Officer may, in the Government's Interest, withhold payment until a reserve not
exceeding $50,000 or 5 percent of the amount of this contract, whichever is
less, shall have been set aside if, in the Contracting Officer's opinion, the
Contractor fails to--

            (i) Convey to the Government, using a DOE-approved form, the title
and/or rights of the Government in each subject invention as required by this
clause.

            (ii) Establish, maintain, and follow effective procedures for
identifying and disclosing subject inventions pursuant to subparagraph (e)(1) of
this clause;

            (iii) Disclose any subject invention pursuant to subparagraph (e)(2)
of this clause;

            (iv) Deliver acceptable interim reports pursuant to subparagraph
(e)(3)(i) of this clause; or

            (v) Provide the information regarding subcontracts pursuant to
subparagraph (h)(4) of this clause.


                                       16
<PAGE>

      (2) Such reserve or balance shall be withheld until the Contracting
Officer has determined that the Contractor has rectified whatever deficiencies
exist and has delivered all reports, disclosures, and other information required
by this clause.

      (3) Final payment under this contract shall not be made before the
Contractor delivers to the Contracting Officer all disclosures of subject
inventions required by subparagraph (e)(2) of this clause, and acceptable final
report pursuant to subparagraph (e)(3)(ii) of this clause, and the Patent
Counsel has issued a patent clearance certification to the Contracting Officer.

      (4) The Contracting Officer may decrease or increase the sums withheld up
to the maximum authorized above. No amount shall be withheld under this
paragraph while the amount specified by this paragraph is being withheld under
other provisions of the contract. The withholding of any amount or the
subsequent payment thereof shall not be construed as a waiver of any Government
rights.

(h) Subcontracts.

      (1) The contractor shall include the clause at 48 CFR 952.227-11 (suitably
modified to identify the parties) in all subcontracts, regardless of tier, for
experimental, developmental, demonstration, or research work to be performed by
a small business firm or domestic nonprofit organization, except where the work
of the subcontract is subject to an Exceptional Circumstances Determination by
DOE. In all other subcontracts, regardless of tier, for experimental,
developmental, demonstration, or research work, the contractor shall include
this clause (suitably modified to identify the parties). The contractor shall
not, as part of the consideration for awarding the subcontract, obtain rights in
the subcontractor's subject inventions.

      (2) In the event of a refusal by a prospective subcontractor to accept
such a clause the Contractor--

            (i) Shall promptly submit a written notice to the Contracting
Officer setting forth the subcontractor's reasons for such refusal and other
pertinent information that may expedite disposition of the matter; and

            (ii) Shall not proceed with such subcontract without the written
authorization of the Contracting Officer.

      (3) In the case of subcontracts at any tier, DOE, the subcontractor, and
Contractor agree that the mutual obligations of the parties created by this
clause constitute a contract between the subcontractor and DOE with respect to
those matters covered by this clause.

      (4) The Contractor shall promptly notify the Contracting Officer in
writing upon the award of any subcontract at any tier containing a patent rights
clause by identifying the subcontractor, the applicable patent rights clause,
the work to be performed under the subcontract, and the dates of award and
estimated completion. Upon request of the Contracting Officer, the Contractor
shall furnish a copy of such subcontract, and, no more frequently than annually,
a listing of the subcontracts that have been awarded.

      (5) The contractor shall identify all subject inventions of the
subcontractor of which it acquires knowledge in the performance of this contract
and shall notify the Patent Counsel, with a copy to the contracting officer,
promptly upon identification of the inventions.

(i) Preference United States industry. Unless provided otherwise, no Contractor
that receives title to any subject invention and no assignee of any such
Contractor shall grant to any person the exclusive right to use or sell any
subject invention in the United States unless such person agrees that any
products embodying the subject invention will be manufactured substantially in
the United States. However, in individual cases, the requirement may be waived
by the Government upon a showing by the Contractor or 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) Atomic energy.

      (1) No claim for pecuniary award of compensation under the provisions of
the Atomic Energy Act of 1954, as amended, shall be asserted with respect to any
invention or discovery made or conceived in the course of or under this
contract.


                                       17
<PAGE>

      (2) Except as otherwise authorized in writing by the Contracting Officer,
the Contractor will obtain patent agreements to effectuate the provisions of
subparagraph (e)(1) of this clause from all persons who perform any part of the
work under this contract, except nontechnical personnel, such as clerical
employees and manual laborers.

(k) Background Patents.

      (1) Background Patent means a domestic patent covering an invention or
discovery which is not a subject invention and which is owned or controlled by
the Contractor at any time through the completion of this contract:

            (i) Which the contractor, but not the Government, has the right to
license to others without obligation to pay royalties thereon, and

            (ii) Infringement of which cannot reasonably be avoided upon the
practice of any specific process, method, machine, manufacture, or composition
of matter (including relatively mirror modifications thereof) which is a subject
of the research, development, or demonstration work performed under this
contract.

      (2) The Contractor agrees to and does hereby grant to the Government a
royalty-free, nonexclusive license under any background patent for purposes of
practicing a subject of this contract by or for the Government in research,
development, and demonstration work only.

      (3) The Contractor also agrees that upon written application by DOE, it
will grant to responsible parties, for purposes of practicing a subject of this
contract, nonexclusive licenses under any background patent on terms that are
reasonable under the circumstances. If, however, the Contractor believes that
exclusive rights are necessary to achieve expeditious commercial development or
utilization, then a request may be made to DOE for DOE approval of such
licensing by the Contractor.

      (4) Notwithstanding subparagraph (k)(3) of this clause, the contractor
shall not be obligated to license any background patent if the Contractor
demonstrates to the satisfaction of the Secretary of Energy or designee that:

            (i) a competitive alternative to the subject matter covered by said
background patent is commercially available or readily introducible from one or
more other sources; or

            (ii) the Contractor or its licensees are supplying the subject
matter covered by said background patent in sufficient quantity and at
reasonable prices to satisfy market needs, or have taken effective steps or
within a reasonable time are expected to take effective steps to so supply the
subject matter.

(l) Publication. It is recognized that during the course of the work under this
contract, the Contractor or its employees may from time to time desire to
release or publish information regarding scientific or technical developments
conceived or first actually reduced to practice in the course of or under this
contract. In order that public disclosure of such information will not adversely
affect the patent interests of DOE or the Contractor, patent approval for
release of publication shall be secured from Patent Counsel prior to any such
release or publication.

(m) Forfeiture of rights in unreported subject inventions.

      (1) The Contractor shall forfeit and assign to the Government, at the
request of the Secretary of Energy or designee, all rights in any subject
invention which the Contractor fails to report to Patent Counsel within six
months after the time the Contractor:

            (i) Files or causes to be filed a United States or foreign patent
application thereon; or

            (ii) Submits the final report required by subparagraph (e)(2)(ii) of
this clause, whichever is later.

      (2) However, the Contractor shall not forfeit rights in a subject
invention if, within the time specified in subparagraph (m)(1) of this clause,
the Contractor:


                                       18
<PAGE>

            (i) Prepares a written decision based upon a review of the record
that the invention was neither conceived nor first actually reduced to practice
in the course of or under the contract and delivers the decision to Patent
Counsel, with a copy to the Contracting Officer or

            (ii) Contending that the invention is not a subject invention, the
Contractor nevertheless discloses the invention and all facts pertinent to this
contention to the Patent Counsel, with a copy to the Contracting Officer; or

            (iii) Establishes that the failure to disclose did not result from
the Contractor's fault or negligence.

      (3) Pending written assignment of the patent application and patents on a
subject invention determined by the Secretary of Energy or designee to be
forfeited (such determination to be a final decision under the Disputes clause
of this contract), the Contractor shall be deemed to hold the invention and the
patent applications and patents pertaining thereto in trust for the Government.
The forfeiture provision of this paragraph (m) shall be in addition to and shall
not supersede other rights and remedies which the Government may have with
respect to subject inventions.

(End of clause)

      privacy or security reasons, and enter a declassification date if the
      sanitized document is also a declassified document. Check "Never
      classified" for documents that have never been classified and are being
      made publicly available.

      2.e. OpenNet Document Categories. For information products which will be
      included in the OpenNet Database, provide the appropriate two-level
      subject categories based on the list in OpenNet DeClassified Information

      c.    The following item No. 10 is added to the Special Terms and

            "10.  FUNDING

            It is the intention of Government and the Participant to share the
            allowable and allocable costs of performance of the work on a 46.7
            percent (Government) and 53.3 percent (Participant) based on the
            total cost of the project in Block No. 16.a(6) of the Notice of
            Financial Assistance Award face page.

            The Government's share obligated in this agreement, in the amount of
            $1,425,057.00, is subject to the following conditions and
            limitations:

            a.    Funds in the amount of $1,425,057.00 are provided for the
                  reimbursement of the Government's share of costs associated
                  with the performance of the Statement of Work attached hereto.

            b.    The parties have 120 days to complete negotiations of the
                  Participant's proposal, dated 10-14-98, submitted in response
                  to Solicitation No. DE-SC02-98EE50525. It is the intent of the
                  Government to issue an amendment for the completion of the
                  entire scope of work, inclusive of the required 50/50 percent
                  cost share within the 120 days. If, after 120 days, an
                  agreement is not reached and an amendment not executed for
                  further work performance, the parties do hereby mutually
                  agree, that the allowable and allocable costs incurred, under
                  this cooperative agreement, shall be reimbursed on a 46.7
                  percent (Government) and 53.3 percent (Participant).
                  Notwithstanding the total costs incurred for work under this
                  agreement, the cost share to the Government shall not exceed
                  $1,425,057.00."

                                                       DE-FCO2-99EE50570

                  ending 9/29/02, on a DOE 50%/SatCon 50% basis. As a result,
                  the Government's contribution toward the aforementioned
                  budget/project period shall be $9,996,964, as specified in
                  Block 15.a.(4) of the face page, and the Recipient's
                  contribution shall be $9,997,044, as specified in Block
                  16.a(5) of the face page. The cost share percentages specified
                  above shall also apply to any increase in the Total Approved
                  Budget, specified in Block 16.a.(6) of the face page.
                  Notwithstanding any other provision in this Agreement, it is
                  understood by the parties that no additional Federal funding
                  above that specified in Block 16.b.(3) of the face page will
                  be provided under this Agreement notwithstanding the total
                  cost of the project at its completion. The Recipient further
                  understands and agrees that it is liable for its pro rata
                  share of the total allowable and allocable costs incurred for
                  work performed under this Agreement in the event the project
                  is terminated early or is not funded to its completion.

            j)    Clause 6, "Partially Funded Financial Assistance Award With
                  Cost Sharing", is hereby added to the "Additional Special
                  Provisions" as follows:

                  "PARTIALLY FUNDED FINANCIAL ASSISTANCE AWARD WITH COST SHARING

                  This award is partially funded on a cost reimbursement basis
                  without fee or profit. The total estimated cost of the project
                  to be conducted during the current budget period specified in
                  Block 6. of the face page is $19,994,008, of which the
                  estimated cost to DOE is $9,996,964 and the estimated cost to
                  the Recipient is $9,997,044. The Cumulative DOE Obligation for
                  the current budget period is $2,413,057, and, subject to the
                  availability of additional funds, DOE anticipates obligating
                  an additional $7,583,907 hereunder for the current budget
                  period. The Recipient shall not be obligated to continue
                  performance of the project beyond the total of (a) the amount
                  of funds set forth as the Cumulative DOE Obligation specified
                  in Block 16.b.(1) of the face page, (b) the amount, if any,
                  set forth as DOE Funds Authorized for Carry Over in Block
                  16.a(2) of the face page, and (c) the amount of the
                  Recipient's current obligation for the current budget period,
                  viz., $2,413,076; provided, however, that, once the Cumulative
                  DOE Obligation has been increased by DOE to $9,996,964, the
                  Recipient's obligation shall be increased to a total amount of
                  $9,997,044, and the Recipient shall be expected to bring this
                  phase of the project (covered by the current budget period) to

                  Contracting Officer to determine the recipient's financial
                  viability, i.e., the recipient has sufficient resources to
                  meet its responsibility under the agreement. Notwithstanding
                  the total costs incurred for work under this agreement, the
                  cost share to the Government for any allowable and allocable
                  costs incurred shall not exceed the amount in block 16 b.(1)

                  "CEILING ON RATES FOR ALLOWABLE OVERHEAD AND GENERAL AND
                  ADMINISTRATIVE COSTS TO BE REIMBURSED BY THE GOVERNMENT

                  Reimbursement by the Government of any allowabe Overhead (OH)
                  costs shall be subject to a ceiling rate of 90% applied to the
                  appropriate base, as proposed, and reimbursement of allowable
                  General and Administrative (G&A) costs shall be subject to a
                  ceiling rate of 36% applied to the appropriate base, as
                  proposed. Any OH or G&A costs in excess of the ceiling rates
                  applicable to the respective bases shall not be reimbursed by
                  the Government nor be considered as cost share under this
                  Agreement or any other Government award.

                  Additionally, it is understood that, consistent with the
                  budget plan, neither OH nor G&A costs shall be applied to the
                  cost share portion of the budget. OH and G&A costs associated
                  with the cost share portion of the budget shall not be

19.   REMARKS (continued)

      a.    The following revisions are effective for performance under this
            cooperative agreement on or after the effective date of this
            amendment:

            (1)   The cumulative DOE obligation for this budget period as
                  refelected in block no. 16.b. (1) of the Notice of Financial
                  Assistance Award is increased by $1,000,000.00 from
                  $4,413,057.00 to $5,413,057.00.

            (2)   Clause 6, "Partially Funded Financial Assistance Award With
                  Cost Sharing", of the Additional Special Provisions is hereby
                  updated to reflect the cumulative DOE obligation for the
                  current budget period of $5,413,057.00, and the corresponding
                  amount of the Recipient's obligation for the budget period,
                  currently $5,413,100.00. DOE's anticipated future obligation
                  is reduced by $1,000,000.00 from $5,583,907.00 to
                  $4,583,907.00.

            (3)   Clause 7 "Authorization of Expenditures" is revised by
                  substituting the year "2001" for the year "2000" in the three
                  places it is used.

      b.    All other terms and conditions remain unchanged and in full force
            and effect.
