However, in each case above, Consultant may be required to work additional days in a week so long as the number of days worked in the next week or subsequent weeks is reduced by the number of extra days so worked. (ii) Consultant shall choose which days he desires to work, although the Chief Executive Officer and the President may require Consultant to work on specific days in accordance with the needs of AER Energy. All of Consultant's duties shall be performed at the principal offices of AER Energy unless otherwise requested by the President or the Chief Executive Officer.

The Board of Directors may, in its discretion, nominate Consultant for election to the Board of Directors for subsequent terms. 2 7. Ownership and Non-Disclosure. (a) Work Product. Except as expressly provided in this Agreement, AER Energy alone shall be entitled to all benefits, profits and results arising from or incidental to Consultant's performance of the consulting services described in this Agreement (the "Services"). To the greatest extent possible, any work product, property, data, documentation or information or materials prepared, conceived, discovered, developed or created by Consultant in connection with performing the Services or any other of his employment responsibilities to date at AER Energy ("Work Product") shall be deemed to be "work made for hire" as defined in the Copyright Act, 17 U.S.C.A. ss. 101 et seq., as amended, and owned exclusively and perpetually by AER Energy. Consultant hereby unconditionally and irrevocably transfers and assigns to AER Energy all intellectual property or other rights, title and interest Consultant may currently have (or in the future may have) by operation of law or otherwise in or to any Work Product. Consultant shall execute and deliver to AER Energy any transfers, assignments, documents or other instruments that AER Energy may deem necessary or appropriate to vest complete and perpetual title and ownership of any Work Product and all associated rights exclusively in AER Energy. AER Energy shall have the right to adapt, change, revise, delete from, add to and rearrange the Work Product or any part thereof written or created by Consultant, and to combine the same with other works to any extent, and to change or substitute the title thereof, and in this connection Consultant hereby waives the "moral rights" of authors as that term is commonly understood throughout the world including, without limitation, any similar rights or principles of law which Consultant may now or later have by virtue of the law of any locality, state, nation, treaty, convention or other source. Unless otherwise specifically agreed, Consultant shall not be entitled to any compensation in addition to that provided for in Section 4 for any exercise by AER Energy of its rights set forth in this Section 7(a). (b) Trade Secrets and Confidential Information. Through exercise of his rights and performance of his obligations under this Agreement, and as President and Chief Executive Officer of AER Energy prior to the date hereof, Consultant has been and will be exposed to "Trade Secrets" and "Confidential Information" (as those terms are defined in this Section 7(b)). "Trade Secrets" shall mean information or data of or about AER Energy or any affiliate or other entity from which AER Energy has licensed or during the Consulting Period will license technology, including, but not limited to, technical or nontechnical data, formulas, patterns, compilations, programs, devices, methods, techniques, drawings, processes, financial data, financial plans, products plans, or lists of actual or potential customers, clients, distributors, or licensees, that: (i) derive economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from their disclosure or use; and (ii) are the subject of efforts that are reasonable under the circumstances to maintain their secrecy. To the extent the foregoing definition is inconsistent with a definition of "trade secrets" mandated under applicable law, the latter definition shall govern for purposes of interpreting Consultant's obligations under this Agreement. "Confidential Information" shall mean valuable, non-public, competitively sensitive data and information relating to the business of AER Energy or any of its affiliates, any other entity from which AER Energy 3 has licensed or during the Consulting Period will license technology, or any other entity to which AER Energy has or will license its technology (including any such technology that is or will be licensed from others) any subsidiary or affiliate, other than Trade Secrets. Consultant acknowledges and agrees that any unauthorized disclosure or use of any Trade Secrets or Confidential Information would be wrongful and would likely result in immediate and irreparable injury to AER Energy. Except as required to perform his obligations under this Agreement or except with Company's prior written permission, Consultant shall not, without the express prior written consent of AER Energy, redistribute, market, publish, disclose or divulge to any other person or entity, or use or modify for use, directly or indirectly in any way for any person or entity: (i) any Trade Secrets at any time (during or after the Consulting Period) during which such information or data shall continue to constitute a "trade secret" under applicable law; and (ii) any Confidential Information during the Consulting Period and for a period of four (4) years after termination of the Consulting Period. Consultant shall cooperate with any reasonable confidentiality requirements of AER Energy. Consultant shall immediately notify AER Energy of any unauthorized disclosure or use of any Trade Secrets or Confidential Information of which Consultant becomes aware. (c) Return of Materials. At any point during the Consulting Period at the specific request of AER Energy, or, in any event, immediately after the Consulting Period has been terminated, Consultant will return to AER Energy all Work Product (including any copies or reproductions thereof and any materials constituting or containing Trade Secrets or Confidential Information of AER Energy) that are in Consultant's possession or control. (d) Acknowledgment. The parties acknowledge and agree that the covenants of Consultant in this Section 7 (collectively, the "Protective Covenants") are reasonable as to time, scope and territory given AER Energy's need to protect its substantial investment in its Work Product, Confidential Information and Trade Secrets, and particularly given (a) the compensation and benefits that are to be provided Consultant, (b) the complexity and competitive nature of AER Energy, and (c) that Consultant has sufficient skills to find alternative, commensurate employment or consulting work in Consultant's field of expertise that would not entail a violation of the Protective Covenants. The parties further acknowledge that any breach or threatened breach of a Protective Covenant by Consultant is likely to result in irreparable injury to AER Energy, and therefore, in addition to all remedies provided at law or in equity (which remedies shall be cumulative and not mutually exclusive), AER Energy shall be entitled to file suit in a court of competent jurisdiction to seek a temporary restraining order and a permanent injunction to prevent a breach or contemplated breach of the Protective Covenant. (e) No Effect of Termination. The termination of the Consulting Period or this Agreement shall not limit or otherwise affect the agreements and covenants set forth in this Section 7. 8. Indemnification. AER Energy shall indemnify Consultant with respect to his service under this Agreement to the full extent permitted by the Georgia Business Corporation Code. 9. Termination. 4 (a) Termination with Cause by AER Energy. AER Energy may terminate its obligations under this Agreement upon the breach or default by Consultant of any provision of this Agreement or any other agreement between Consultant and AER Energy if such breach or default is not remedied within thirty days after written notice thereof to Consultant. (b) Termination on Account of Death or Medical Disability. AER Energy may terminate its obligations under this Agreement upon the death of Consultant or upon the expiration of 60 days following the commencement of a continuous period of medical disability (either physical or mental) of Consultant causing him to have been substantially unable to perform his duties pursuant to this Agreement for such sixty-day period; provided, however, that any stock option which has previously been granted to Consultant (as such agreement may be amended) shall continue in effect to the extent provided in the stock option agreement. A state of "medical disability" may be conclusively established by the parties' agreement that such state exists or by the issuance of a letter confirming such disability written by a duly licensed and practicing physician selected by AER Energy. A state of medical disability shall commence upon the first day Consultant is substantially unable to perform his duties hereunder because of any medical disability. 10. Releases. (a) Mutual Releases. Consultant hereby releases, discharges and acquits forever the AER Energy Releasees (as defined below) from any and all debts, claims, demands, liabilities, assessments, actions or causes of action, whether in law or in equity, whether direct or indirect, whether presently known or unknown, absolute or contingent, arising under any law, rule, regulation, ordinance, agreement, guideline or other standard of conduct of any kind whatsoever (collectively, "Claims") which Consultant had, now has, or may have had against any of the AER Energy Releasees from the beginning of time up to the date of this Agreement. Except as provided in Section 10(c), AER Energy hereby releases, discharges and acquits forever Consultant from any and all Claims which AER Energy had, now has, or may have had against Consultant from the beginning of time up to the date of this Agreement. Unless the context plainly requires otherwise, the term "AER Energy Releasees" includes AER Energy and its owners, shareholders, directors, officers, partners, agents, attorneys, parent entities, employees, successors, assigns, affiliates and subsidiaries, and each of their respective owners, shareholders, directors, officers, partners, agents, attorneys, parent entities, employees, successors, assigns, affiliates and subsidiaries. (b) Employment-Related Claims. Without limiting the foregoing release, Consultant waives all rights he may have had or now has to pursue any and all remedies available to him under any cause of action whatsoever against the AER Energy Releasees, including without limitation, claims of wrongful discharge, emotional distress, defamation, breach of contract, breach of the covenant of good faith and fair dealing, the Employee Retirement Income Security Act, and any other laws and regulations relating to employment, including any and all employment laws of the State of Georgia. Consultant further acknowledges and expressly agrees that he is waiving any and all 5 rights he may have had or now has to pursue any claim of discrimination, including but not limited to, any claim of discrimination based on sex, age, race, national origin, disability, or on any other basis, under Title VII of the Civil Rights Act of 1964, the Americans With Disabilities Act of 1990, the Equal Pay Act of 1963, the Age Discrimination in Employment Act of 1967, the Civil Rights Act of 1866, any other analogous law of the State of Georgia, and all other laws and regulations relating to employment. (c) Exception for Ownership and Non-Disclosure Claims. Notwithstanding anything in Section 10(a) to the contrary, AER Energy shall be permitted to assert against Consultant a Claim arising out of an alleged breach of any agreement, representation or covenant contained in Section 7 hereof. 11. Miscellaneous. (a) Severability. All the agreements set forth in this Agreement are independent agreements and severable from one another, and the unenforceability or invalidity of any provision of this Agreement shall not affect the validity or enforceability of the remaining provisions of this Agreement; provided, however, that should any judicial body interpreting this Agreement deem any provision to be unreasonably broad in time, territory, scope or otherwise, AER Energy and Consultant intend for the judicial body, to the greatest extent possible, to reduce the breadth of the provision to the maximum legally allowable parameters rather than deeming such provision totally unenforceable or invalid. (b) Assignment; Successors in Interest. Except for the transfer of options by will or the laws of descent and distribution as provided in the stock option agreement described in Section 4 of this Agreement, Consultant shall have no right to assign or transfer any or all of his rights and obligations under this Agreement without the prior written consent of AER Energy. This Agreement shall be binding upon the parties to this Agreement and their respective legal representatives, heirs, devises, legatees and successors and assigns (whether or not permitted), shall inure to the benefit of the parties to this Agreement and their respective permitted legal representatives and permitted successors and assigns, and any reference to a party to this Agreement shall also be a reference to a successor or permitted assign.
