provide the other party with a written statement of the facts of the
infringement or opposition, to the extent known. Within a reasonable time
thereafter, including time to satisfy itself as to the facts, with respect to a
notice of a third party infringement, the owner of the Patent shall have the
right to bring suit to enjoin such infringement and to recover damages therefor
and to select counsel for the prosecution of any such infringement suit.

        (b) If one party chooses not to bring such an infringement suit, the
other party may, at its own expense and in the name of the owner or in its own
name, or both, bring suit to enjoin such infringement and to recover damages
therefor and to select counsel for the prosecution of any such infringement
suit.

        (c) Any damages collected in any suit pursued by a single party shall
first be applied to the reimbursement of litigation expenses of the party
bringing suit and second to the reimbursement of any reasonable expenses
incurred by the other party in support of such suit. Any remaining damages shall
belong to the party bringing suit.

        (d) If both parties jointly instigate infringement or opposition
proceedings both parties shall share the costs and the receipt of damages on an
equitable basis which shall be as agreed by the parties, or in the absence of
such agreement, shall be based on a commercially reasonable determination of the
respective interests of the parties in enjoining the infringement and the
relative damages suffered.

receiving party to any other party without the prior written consent of the
disclosing party, except as authorized herein. The parties agree to use their
best efforts to maintain the confidentiality of the Confidential Information
disclosed to them and each shall use no less than the same safeguards as its
uses to protect its own confidential information of a similar nature.

7.2 Non-Disclosure. The receiving party shall disclose Confidential Information
only to its officers, employees, and third party consultants whose duties
reasonably require familiarity with such information. The receiving party shall
obtain from such third party consultants legally enforceable undertakings not to

purposes other than those contemplated by this Agreement. Except as otherwise
agreed by the parties, the receiving party shall be required to take such legal
actions, at its own expense, as may be reasonably necessary to enforce such
undertakings.

7.3 Exceptions. The confidentiality obligation of the receiving party under
Sections 7.1 and 7.2 shall not apply to Confidential Information which:

        (a) is or becomes publicly known through no wrongful act of the
receiving party or its employees;

9.1 Term; Termination. Unless earlier terminated pursuant to this Section 9.1 or
Section 11.13, this Agreement shall terminate ten (10) years from the Effective

other party fails to perform any material obligation or undertaking to be
performed by it under this Agreement, and such failure shall not be cured within
ninety (90) days after written notice thereof from the other party, specifying
in detail the nature of the breach and indicating the other party's intent to

(150) days after such notice is given, and provided further that any failure to
make payments due under this Agreement shall not be subject to such 90 and

this Article 9 or Section 11.13, all obligations undertaken by the parties

9.3 Continuing Liabilities. Termination of this Agreement for any reason shall
not release any party hereto from any liability which, at the time of such
termination, has already accrued to the other party or which is attributable to
a period prior to such termination, or constitute a waiver of, or preclude
either party from pursuing, any rights and remedies it may have hereunder or at
law or in equity which accrued or are based upon any event occurring prior to
such termination.

                   ARTICLE 10 - DEMI PAYMENTS, NET WORTH, ETC.

10.1 DEMI Agreement. If AER fails to pay DEMI the dollar amounts set forth on
Appendix 4 of the DEMI Agreement (under the provisions of Section 2(b) thereof)
or in the event AER fails to meet the minimum royalty payments as set forth in
Appendix 5 of the DEMI Agreement, then within thirty (30) business days of the
date any such payment is due, AER shall give notice to DURACELL in order to
afford DURACELL the opportunity to make these payments to DEMI so as not to lose
the exclusive worldwide right and license to use the Licensed Rights granted
from DEMI and CHEIKY to AER. If DURACELL makes any such payment to DEMI on
behalf of AER, AER will reimburse DURACELL within thirty (30) days after such
payment by DURACELL.

10.2 Net Worth. AER will use its best efforts to maintain a positive net worth
(total assets minus total liabilities as determined under generally accepted
accounting principles, consistently applied) and pay its debts as they mature.
If AER files a petition under Chapter 7 of the United States Bankruptcy Code,
prior to so doing, it shall notify DURACELL of its intention to file such a
petition, and upon request of DURACELL, AER will sell to DURACELL, for its then
fair market value, any of AER's Pilot Line, Production Line, [ ]* Cells in
inventory, [ ]* Cells in inventory, work in progress related thereto and related
support tools and fixtures, and DURACELL may make an offer to purchase all or
part of the AER Technology but AER shall be under no obligation to accept any
such offer. The licenses set forth in this Agreement will survive any bankruptcy
of AER pursuant to Section 365(n) of the United Sates Bankruptcy Code.

10.3 Return of DURACELL Equipment. If AER files a petition under Chapter 7 of
the United States Bankruptcy Code, prior to so doing, it will return to DURACELL
all materials and Equipment which have been designated for the Program and paid
for by DURACELL.

10.4 Periodic Reports. Promptly after filing, AER will deliver to DURACELL
copies of all periodic reports AER files with the Securities and Exchange
Commission, and appropriate AER personnel will review such periodic reports with
appropriate DURACELL personnel.

                           ARTICLE 11 - MISCELLANEOUS

respective obligations under this Agreement.

DURACELL'S or AER's rights with respect to the ownership, development, license
and sale of [ ]* battery technology.

11.4 Independent Contractors. The parties hereto are independent contractors and
shall have no power, nor will either of the parties represent that either has
any power, to bind the other party or to assume or to create any obligation or
responsibility, expressed or implied, on behalf of the other party or in other
party's name. This Agreement shall not be construed as constituting DURACELL,
and AER as partners or as creating any other form of legal association which
would impose liability upon one party for the act or failure to act of the
other.

11.5 Overdue Payments. In addition to all other remedies available under this
Agreement or applicable law, payments provided for in this Agreement shall, when
overdue, be subject to a late payment charge calculated monthly at a fluctuating
rate of interest equal to two percent (2%) over the prime rate (or equivalent
designation) announced by Citibank, N.A., New York City, during delinquency;
provided, however, that if the amount of such late payment charge exceeds the
maximum permitted by law for any such charge, such charge shall be reduced to
such maximum amount. In the event that such prime rate (or equivalent
designation) shall be discontinued or become unavailable for any reason, the
prime rate (or equivalent designation) of another bank in New York City shall be
selected by AER and approved by DURACELL, which approval shall not be
unreasonably withheld.

11.6 Severability. In the event that any part of this Agreement shall be
determined to be in violation of any statute, rule of law, governmental
regulation or decree of a court of competent jurisdiction, or unenforceable for
any reason, such part shall be deemed severed from this Agreement, but the
remainder of this Agreement shall continue in full force and effect.

11.7 No Waiver. The failure of either party to exercise any right or to demand
the performance by the other party of duties required hereunder shall not
constitute a waiver of any rights or obligations provided for herein.

11.8 Governing Law. This Agreement shall be governed by and construed in
accordance with, and the legal relations between the parties hereto shall be
determined in accordance with, the laws of the State of Connecticut, without
regard to any laws relating to conflicts of law.

11.9 Arbitrator. If any dispute shall arise between the parties hereto as to any
matter relating to this Agreement, or the breach hereof, the parties hereto
shall negotiate with each other in good faith and attempt to reach an amicable
resolution of such dispute. If, after negotiating in good faith, the parties are
unable to resolve such dispute on an amicable basis within a period of ninety
(90) days, either party may submit the dispute to binding arbitration pursuant
to the Commercial Arbitration Rules of the American Arbitration Association. The
place of arbitration shall be Hartford, Connecticut. The parties shall be bound
by any award issued as a result of such arbitration and such

anywhere in the world and in any event service of any and all process on any
party hereto in any suit, action or proceeding arising out of this Agreement may
be made in accordance with applicable law to the address set forth for such
party in Section 11.11 (as the same may be changed pursuant to the provisions of
Section 11.11), and service thus made shall be taken and held to be valid
personal service upon such party.

11.10 Force Majeure. No party shall be liable to any other for failure or delay
in the performance of any of its obligations under this Agreement for the time
and to the extent such failure or delay is caused by riots, civil commotion,
wars, hostilities between nations, governmental laws, orders or regulations,
embargoes, actions by government or agency thereof, acts of God, storms, fires,
accidents, labor disputes or strikes, sabotage, explosions or other similar or
different contingencies, in each case, beyond the reasonable control of the
respective party. If the performance of any obligation under this Agreement is

however, that any party may assign its rights and obligations under this
Agreement to an Affiliate without the consent of the other party or parties
provided that the assigning party hereto remains liable, together with any such
assignee, for all of its respective obligations under this Agreement and
provided further that notwithstanding anything to the contrary in this

                                    AGREEMENT

        For $1.00 and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, AER Energy Resources, Inc., a
Georgia corporation ("AER"), Michael Cheiky, a California resident ("Cheiky"),
Dreisbach Electromotive, Inc., an Ohio corporation ("DEMI"), and Duracell, Inc.,
a Delaware corporation ("DURACELL"), hereby agree, as follows:

        1. DEMI Agreement. AER, Cheiky and DEMI represent and warrant to
DURACELL that AER, Cheiky and DEMI are parties to a License Agreement dated as
of July 19, 1989 (the "Original License Agreement"), which has been amended by
the following agreements: DEMI/AER Air Manager Agreement dated as of January 16,
1992; Amended and Restated DEMI/AER Air Manager Agreement dated as of October
15, 1993; Consent to Partial Assignment of Royalties and Amendment No. 2 to
License Agreement dated as of October 15, 1993 and Amendment No. 3 to License
Agreement and Termination of Technology Assignment Agreement dated as of
December 26, 1995, all by and among AER, Cheiky and DEMI. AER, Cheiky and DEMI
further represent and warrant to DURACELL that (a) the Original License
Agreement and the above-mentioned subsequent amendments and supplementary
agreements represent all of the amendments and supplementary agreements relating
to the Original License Agreement (the Original License Agreement and such
amendments and supplementary agreements are herein referred to collectively as
the "DEMI License"); and (b) the DEMI License is in full force and effect and no
party is in default under the DEMI License.

        2. No Objections. Cheiky and DEMI agree that each has reviewed the
Technology Licenses and Services Agreement dated September 24, 1998 between
DURACELL and AER (the "DURACELL Agreement") and Cheiky and DEMI have no
objections to the provisions of the DURACELL Agreement or AER's execution and
delivery of the DURACELL Agreement.

        3. Non-Applicability of Certain Provisions. Section 11, the third
sentence of Section 15, and Sections 17 and 18 of the DEMI License shall not
apply to DURACELL, as a Sublicensee under the DEMI License.

        4. No Rights. Notwithstanding any provisions of the DEMI License to the
contrary: (a) DEMI and Cheiky each shall have no rights to any Program
Technology or DURACELL Technology or both (as "Program Technology" and "DURACELL
Technology" are defined in the DURACELL Agreement), and (b) the last sentence of
Section 1(e) and the proviso to Section 2(a) of the DEMI License shall not apply
to DURACELL, and (c) with respect to products which DURACELL or any of its
Sublicensees manufactures, makes, has made, uses, sells, offers to sell or
leases, DEMI or the Shareholders' Agent (as defined in the DEMI License) shall
be paid royalties by AER under the DEMI License through July 19, 2004, only with
respect to Net Sales (as defined in the DURACELL Agreement) for which DURACELL
pays AER, and through July




<PAGE>   32



19, 2004, AER will pay royalties to DEMI or the Shareholders' Agent at a rate of
four percent (4%) of such Net Sales with respect to all Net Sales with respect
to which DURACELL or any of its Sublicensees pays AER under the DURACELL
Agreement. After July 19, 2004, no royalties will be owed by AER under the DEMI
License. AER will use its best efforts to cause DURACELL to pay to AER all
amounts owed by DURACELL to AER under the DURACELL Agreement. DEMI and Cheiky
acknowledge and agree that under the DEMI License, AER and not its Sublicensees
is responsible for paying royalties to DEMI; provided, however, that in the
event DURACELL breaches the DURACELL Agreement by failing to pay royalties to
AER in accordance with the provisions of the DURACELL Agreement and AER fails to
cause DURACELL to meet its royalty obligations under the DURACELL Agreement
within 60 days after the breach by DURACELL, (i) DEMI shall be entitled to
proceed directly against DURACELL to recover any amounts owed by AER to DEMI
under the DEMI License, and (ii) DEMI shall retain all rights under applicable
law to seek damages and injunctive relief from DURACELL for DURACELL's use of
patents and other Aerobic Power Technology (as defined in the DEMI License)
owned by DEMI.

        5. Indemnification. DURACELL and AER shall each, severally but not
jointly, defend, hold harmless and indemnify DEMI and its past, present and
future directors, officers, employees, affiliates, successors and assigns,
during the term of this Agreement and thereafter from and against any and all
liability, costs and expenses (collectively "Costs") arising out of (i) the
death or injury to any person or persons or damage to property resulting from
any negligence, fault or defect in the manufacture or design of products or
components manufactured by or for DURACELL or AER, respectively; or (ii) its
failure to comply with relevant laws, rules, regulations, ordinances, permits or
licenses. DEMI shall promptly notify DURACELL or AER or both, as appropriate, in
writing after notice of such claim is received, and shall give DURACELL or AER
or both, as appropriate, reasonable assistance at DURACELL's or AER's expense,
respectively, in the defense of such claim. Upon receipt of notice, whether
formal or informal, direct or indirect, of any action for which indemnification
may be available under this Section 5, the party receiving notice shall notify
the other or others and their senior management shall meet to discuss how to
handle the matter.

        6. DURACELL Rights Continue. If AER ceases operations or terminates or
proposes to terminate the DURACELL Agreement, or if the DEMI License is rejected
in any proceeding under the United States Bankruptcy Code or other insolvency
laws, Cheiky and DEMI shall allow DURACELL to maintain in force the licenses set
forth in Sections 3.2 and 3.5 of the DURACELL Agreement and shall take no action
to impair DURACELL's licenses set forth in Sections 3.2 and 3.5 of the DURACELL
Agreement, upon payment directly to DEMI of the royalties set forth in the DEMI
License which would be payable to DEMI by AER under the DEMI License with
respect to products sold by DURACELL under the DURACELL Agreement.

        7. Future Amendments to DEMI License. During the term of the DURACELL
Agreement, AER, Cheiky and DEMI agree that the DEMI License will not be amended
or

                                      A-ii

modified in a manner which adversely effects DURACELL without the written
consent of DURACELL, which consent shall not be withheld unreasonably.

        8. No Other Changes. DEMI, Cheiky and AER agree that except as modified
above, the DEMI License remains in full force and effect.
