The terms and provisions of the option will be similar in all other material respects to the other options granted to the senior executives of the Company. (ii) The Company and the Executive have agreed in principle that a grant of 1,000,000 options in the aggregate over five (5) years is the expected grant amount to be made over such period of employment, which grants would be at the discretion of the Board, assuming Executive's satisfactory performance of his duties hereunder. In light of this expectation, the Board will review the number of options granted to the Executive at least annually beginning in the fourth fiscal quarter of 1993.

(i) Any base salary or Minimum Bonus payable to the Executive for any period of employment of less than a year during the Term of Employment will be reduced to reflect the actual number of days of employment during the period except as provided in Section 8(b). Section 5. Other Benefits. (a) During the Term of Employment, the Executive and his family may participate in and receive benefits under any employee benefit plan which the Company makes generally available to its employees and their families, including any pension, life insurance, medical benefits, dental benefits or disability plan, but only to the extent that the Executive or his family otherwise satisfies the standards established for participation in the plan. (b) The Executive may take up to four weeks of vacation during each full calendar year during the Term of Employment, without loss of compensation or other benefits under this Agreement. Section 6. Confidentiality and Post-Employment Restrictions. (a) The Executive acknowledges that the Company has confidential information and trade secrets, whether written or unwritten, with respect to carrying on its business, including sensitive technology and engineering information and data, names of past, present and prospective customers and vendors of the Company, methods of pricing contracts and income and expenses associated therewith, negotiated prices and offers outstanding, credit terms and status of accounts and the terms or circumstances of any business arrangements between the Company and any third parties ("Confidential Information and Trade Secrets"). As used in this Agreement, the term Confidential Information and Trade Secrets does not include (i) information which becomes generally available to the public other than as a result of a disclosure by the Executive, (ii) information which becomes available to the Executive on a nonconfidential basis from a source other than the Company, or (iii) information known to the Executive prior to any disclosure to him by the Company. The Executive further acknowledges that the Executive possesses a high degree of knowledge of the geothermal energy industry and, in particular, has committed to a long-standing relationship with the Company as employee, director and officer, which has allowed, and will continue to allow, him access to the Company's Confidential Information and Trade Secrets. Accordingly, any employment by the Executive with another employer in the geothermal energy industry or participation by him as a substantial investor in any such industry may necessarily involve disclosure of the Company's Confidential Information and Trade Secrets. Consequently, the Executive agrees that, if he voluntarily resigns his employment with the Company for any reason other than a breach of this Agreement by the Company, he shall not at any time during the two-year period after such resignation, directly or indirectly accept employment by or invest in (except as a passive investor in a public corporation or in a publicly issued partnership interest which, in either event, would not exceed an ownership interest of 3% of the outstanding equity or partnership interest) in any person, firm, corporation, partnership, joint venture or business which is primarily engaged in the production or marketing of electrical energy from geothermal resources. (b) Without the Consent of the Board, the Executive will not, for two years after the Term of Employment, (i) disclose any Confidential Information and Trade Secrets of the Company or any Affiliate of the Company to any Person (other than the Company, directors, officers or employees of the Company or representatives thereof), or (ii) otherwise make use of any Confidential Information and Trade Secrets other than in connection with authorized dealings with or by the Company. (c) For a period of two years after the Term of Employment, the Executive shall neither directly nor indirectly solicit, on behalf of another employer, the employment of any person who is then currently employed by the Company, or otherwise induce, on behalf of another employer, such person to leave the employment of the Company without the Company's prior written approval. (d) The Executive will hold, on behalf of the Company and as the property of the Company, all memoranda, manuals, books, papers, letters, documents, computer software and other similar property obtained during the course of his employment by the Company and relating to the Company's business, and will return such property to the Company at any time upon demand by the Board and, in any event, within five calendar days after the end of the Term of Employment. Section 7. Termination of Employment. (a) The employment of the Executive under this Agreement will terminate on the earliest of: (i) written notice by the Executive of his resignation; (ii) the 30th calendar day after the Company gives to the Executive written notice of termination without Cause; (iii) the fifth calendar day after the Company gives to the Executive written notice of the existence of Cause; (iv) the 30th calendar day after the Executive gives to the Company written notice of (A) the failure by the Company to pay to the Executive, for a material period of time and in a material amount, compensation due and payable by the Company under Section 4(a) or 4(c), or (B) any breach by the Company or the Board of Section 3(b) or Section 4(b); (v) the Permanent Disability of the Executive; or (vi) the death of the Executive. (b) If the employment of the Executive is terminated under this Agreement, the obligations of the Executive under Section 6 will remain in full force and effect, and the termination will not abrogate any rights or remedies of the Company or the Executive with respect to any breach of the Agreement, except as expressly provided in Sections 8 and 9. Section 8. Payment Upon Termination. (a) If the employment of the Executive is terminated pursuant to subsections (i), (iii), (v), or (vi) of Section 7(a), the Company will pay to the Executive, within 30 calendar days, (i) any salary pursuant to Section 4(a) which is accrued but unpaid through the Termination Date, and (ii) a bonus payment, in an amount determined by the Board by reference to the performance of the Executive for the portion of the fiscal year of the Company before the Termination Date, which is not less than a pro rata share (determined by reference to the portion of the fiscal year before the Termination Date) of the Minimum Bonus. (b) If the employment of the Executive is terminated pursuant to subsection (ii) or subsection (iv) of Section 7(a), the Company will pay the Executive, on or before the related Termination Date, an amount equal to twice the sum of the annual salary and Minimum Bonus then in effect pursuant to Section 4. In addition, any portion of the options granted pursuant to Section 4 which would become vested within the next 24 months (beginning with the month following the month in which the Termination Date occurs) will vest immediately and may be exercised within the remaining term of the options as provided in the option agreement. Section 9. Remedies. (a) The Company will be entitled, if it elects, to enjoin any breach or threatened breach of, or enforce the specific performance of, the obligations of the Executive under Sections 3 or 6, without showing any actual damage or that monetary damages would be inadequate. Any such equitable remedy will not be the sole and exclusive remedy for any such breach, and the Company may pursue other remedies for such a breach. (b) Any court proceeding to enforce this Agreement may be commenced in the federal courts, or in the absence of federal jurisdiction the state courts, located in Omaha, Nebraska. The parties submit to the jurisdiction of such courts and waive any objection which they may have to pursuit of any such proceeding in any such court. (c) Except to the extent that the Company elects to seek injunctive relief in accordance with subsection (a), any controversy or claim arising out of or relating to this Agreement or the validity, interpretation, enforceability or breach of this Agreement will be submitted to arbitration in Omaha, Nebraska, in accordance with the then existing rules of the American Arbitration Association, and judgement upon the award rendered in any such arbitration may be entered in any court having jurisdiction. (d) The Company will pay, promptly upon request, any legal fees or expenses incurred by the Executive in connection with any legal proceedings instituted by the Company to enforce the provisions of this Agreement against the Executive, but such advances will be reimbursable to the Company, but only to the extent the Company ultimately prevails in the proceeding (after any applicable appeals have been exhausted). Section 10. Assignment. Neither the Company nor the Executive may sell, transfer or otherwise assign their rights, or delegate their obligations, under this Agreement. Section 11. Unfunded Benefits. All compensation and other benefits payable to the Executive under this Agreement will be unfunded, and neither the Company nor any affiliate of the Company will segregate any assets to satisfy any obligation of the Company under this Agreement. The obligations of the Company to the Executive are not the subject of any guarantee or other assurance of any Person other than the Company. Section 12. Severability. Should any provision, paragraph, clause or portion thereof of this Agreement be declared or be determined by any court or arbitrator of competent jurisdiction to be illegal, unenforceable or invalid, the validity or enforceability of the remaining parts, terms or provisions shall not be affected thereby and said illegal or invalid part, term or provision shall be deemed not to be a part of this Agreement. Alternatively, the court or arbitrator having jurisdiction shall have the power to modify such illegal, unenforceable or invalid provision so that it will be valid and enforceable, and, in any case, the remaining provisions of this Agreement shall remain in full force and effect. Section 13. Miscellaneous. (a) This Agreement may be amended or modified only by a writing executed by the Executive and the Company. (b) This Agreement will be governed by and construed in accordance with the internal laws of the State of Nebraska. (c) This Agreement constitutes the entire agreement of the Company and the Executive with respect to the matters set forth in this Agreement and supersedes any and all other agreements between the Company and the Executive relating to those matters.
