ARTICLE 4 --------- COMPANY BENEFITS ---------------- 4.1 Vacation -------- The Employee shall be entitled to receive four weeks of paid vacation per calendar year (pro rated for any partial year), which shall be taken at such time or times as will not unreasonably hinder or interfere with the Company's business or operations. 4.2. Severance Benefit ----------------- If during the Employee's employment pursuant to this Agreement, the Employee ceases to be employed by the Company as a result of the Company's termination of the Employee without cause pursuant to Section 7.4 (which shall not include any termination that is otherwise within Article 6) or the Employee's termination of his employment for good reason pursuant to Section 7.1, the Company shall pay the Employee as a severance benefit, (a) his then base salary plus (b) an amount equal to the Employee's bonus from the Company, if any, for the immediately preceding year.

The Employee understands and agrees that following the spin-off of the Battery Company, if it occurs, his employment may include acting as Chief Financial Officer of the Battery Company during an indefinite period. 4.4. Other Benefit Plans ------------------- The Employee shall further be entitled to participate in and receive benefits under any retirement, life insurance, accident, disability, health and dental insurance, profit sharing, or similar plans generally made available to its employees. 4.5. Indemnification --------------- The Company agrees to defend and shall indemnify and hold the Employee harmless to the fullest extent permitted by law from any and all liability, costs, and expenses which may be assessed against the Employee by reason of the performance of his responsibilities and duties under the terms of this Agreement, provided such liability does not result from willful misconduct or gross negligence of the Employee. ARTICLE 5 --------- RESTRICTIONS ------------ 5.1 Non-Competition --------------- (a) So long as the Employee is employed by the Company and for a period of two years thereafter (the "Noncompetition Period"), the Employee shall not, directly or indirectly, whether as owner, partner, shareholder, director, consultant, agent, employee, guarantor, surety or otherwise, or through any person, consult with or in any way aid or assist any competitor of the Company or engage or attempt to engage in any employment, consulting or other activity which directly or indirectly competes with the Business of the Company. For purposes of this Agreement, the term "employment" shall include the performance 4 of services by Employee as an employee, consultant, agent, independent contractor or otherwise and the term "Business" shall mean the research, development, manufacture, sale or distribution of fuel cells, batteries or related products and any other business engaged in, planned or under development by the Company with respect to which the Employee has had access to Company confidential information during the Noncompetition Period. The Employee acknowledges that his participation in the conduct of any such Business alone or with any person other than the Company will materially impair the Business and prospects of the Company. (b) In addition to and without limiting the foregoing, during the Noncompetition Period, Employee shall not knowingly do, attempt to or assist any other person in doing or attempting to do any of the following: (i) hire any director, officer, employee, or agent of the Company (a "Company Employee") or encourage any such person to terminate such relationship with the Company, as the case may be (for purposes hereof, the Employee shall be deemed to have so encouraged a Company Employee to terminate such relationship with the Company if the Employee hires or otherwise assists any person in hiring any such Company Employee within six months after the Company Employee terminates his or her relationship with the Company), (ii) encourage any customer, client, supplier or other business relationship of the Company to terminate or alter such relationship, whether contractual or otherwise, to the disadvantage of the Company; (iii) encourage any prospective customer or supplier not to enter into a business relationship with the Company; (iv) impair or attempt to impair any relationship, contractual or otherwise, written or oral, between the Company and any customer, supplier or other business relationship of the Company; or (v) sell or offer to sell or assist in or in connection with the sale to any customer or prospective customer of the Company any products of the type sold or rendered by the Company.

Intellectual Property --------------------- Upon execution of this Agreement, the Employee shall execute the Energy Research Corporation Agreement for Assignment, Confidentiality and Nonsolicitation, which agreement is hereby incorporated herein by reference. 5.3. Injunctive Relief ----------------- The Employee acknowledges that the restrictions contained in this Article are reasonable in view of the nature of the business in which the Company is engaged and his position with the Company which will provide him with extensive knowledge of the business. The Company and the Employee mutually agree that the Employee's obligations under this Article are of a special and unique character which gives them a peculiar value, and the Company cannot be reasonably or adequately be compensated in damages in an action at law in the event the Employee breaches such obligations. The Employee therefore expressly agrees that, in addition to any other rights or remedies which the Company may possess, the Company shall be 5 entitled to injunctive and other equitable relief to prevent a breach of this Article by the Employee, including a temporary restraining order or temporary injunction from any court of competent jurisdiction restraining any threatened or actual violation, and each party hereby consents to the entry of such order and injunctive relief and waives the making of a bond as a condition for obtaining such relief. Such rights shall be cumulative and in addition to any other legal or equitable rights and remedies the Company may have. 5.4. Survival Enforceability ----------------------- It is expressly agreed by the parties hereto that the provisions of this Article shall survive the termination of this Agreement. If any one or more of the provisions contained in this Article shall for any reason in any jurisdiction be held to be excessively broad as to the time, duration, geographical scope, activity or subject, it shall be construed with respect to such jurisdiction, by limiting or reducing it, so as to be enforceable to the extent compatible with the applicable law of such jurisdiction as it shall then appear. ARTICLE 6 --------- DEATH; DISABILITY ----------------- 6.1 Death ----- If the Employee dies while employed under this Agreement, this Agreement shall terminate immediately. The Company will pay to the Employee's estate his base salary under Section 3.1 through the last day of the calendar month in which he dies, plus any incentive compensation awarded to the Employee under the Incentive Compensation Plan, but not yet paid, and such death benefits as may be provided pursuant to Section 4.4. 6.2. Disability ---------- If the Employee fails to perform his duties under this Agreement due to "Disability", as defined below, the Company may terminate this Agreement upon 30 days written notice to him. In that event, the Company shall pay the Employee his base salary under Section 3.1 through the date of termination; provided, however, that to the extent the Employee is receiving disability benefits pursuant to the Company's disability insurance policy, the amount of such benefits shall be credited against the Employee's base salary during the period prior to the date of termination. In addition, upon any termination based upon Disability, the Company shall pay to the Employee any incentive compensation awarded to the Employee under the Incentive Compensation Plan but not yet paid. The term "Disability" shall mean the inability of the Employee to perform for the Company the duties specified in Section 1.1 by reason of any medically determinable physical or mental impairment for (i) a period of four consecutive months, (ii) for shorter periods aggregating five months in any 12-month period or (iii) if the Board of Directors determines that it is probable that the Disability will continue for a length of time so as to constitute a Disability under clauses (i) or (ii) above. The determination of whether the Employee is Disabled shall be made by the Board of Directors on the basis of written medical evidence reasonably satisfactory to it. Notwithstanding anything to the contrary 6 in the foregoing, in the event of a termination of the Employee pursuant to clause (iii), the Company will pay the Employee a minimum of four months base salary following such termination; provided, however, that to the extent the Employee is receiving disability benefits pursuant to the Company's disability insurance policy, the amount of such benefits shall be credited against the Employee's base salary.

For purposes of clause (a) a material breach by the Company shall include a material change in the reporting responsibilities of the Employee such that the Employee is no longer effectively serving as the Chief Financial Officer of the Company, a material reduction in benefits or other perquisites of office such that the Employee is not receiving the benefits set forth herein or the benefits and other perquisites generally granted for executive positions within the Company. For purposes of clause (c) above, a "change of control" shall be presumed to have occurred if within any 12-month period a single person or entity, or related group of persons or entities, acquires 50% or more of the outstanding voting stock of the Company. In the event of a termination for good reason under this Section, the Company shall pay the Employee (i) his base salary as then in effect under Section 3.1 through the date of termination, (ii) any incentive compensation awarded to the Employee under the Incentive Compensation Plan, but not yet paid, and (iii) the severance benefit set forth in Section 4.2. 7.2.
