EXECUTIVE EMPLOYMENT AND SEVERANCE AGREEMENT

This Agreement (“Agreement”) is between the individual named above (“Executive”), and Orion Energy Systems, Inc. (“Orion”) effective as of the date set forth above (“Effective Date”).

WHEREAS, Orion desires to employ Executive (by itself or through one of its affiliates, and “Orion” shall be deemed to include any such affiliate, if applicable, when used herein), and Executive desires to be employed by Orion under the terms and conditions set forth herein.

NOW, THEREFORE, for good and valuable consideration, the parties agree as follows:

1. Effective Date; Term. This Agreement shall become effective on the Effective Date and continue until the end of the initial term set forth above (“Initial Term”). The employment status of the Executive will be reviewed by Orion prior to the end of the Initial Term (and the end of any subsequent renewal period term thereafter). Upon such review, Orion may choose not to extend Executive’s employment under this Agreement for an additional renewal period term as set forth above and, upon such a determination, shall provide written notice to such effect to Executive prior to the end of the Initial Term (or the end of any subsequent renewal period term thereafter). If Orion does not provide Executive with such notice of non-renewal prior to the end of the Initial Term (or the end of any subsequent renewal period term), then the term of this Agreement shall be extended for the renewal period set forth above. Notwithstanding the foregoing, if a Change of Control occurs prior to the end of the Initial Term (or the end of any subsequent renewal period term), this Agreement and the Initial Term (or the applicable subsequent renewal period term) shall be automatically extended for the post-Change of Control renewal period set forth above beginning on the date of the Change of Control.

4. Termination of Employment. A Termination Date shall occur as follows:

(a) Executive’s employment will terminate upon Executive’s death.

(b) If Executive suffers a Disability, and if within thirty (30) days after Orion notifies the Executive in writing that it intends to terminate Executive’s employment because of such Disability, Executive shall not have returned to the performance of Executive’s duties hereunder on a full-time basis, then Orion may terminate Executive’s employment, effective immediately following the end of such thirty (30)-day period.

(c) Orion may terminate Executive’s employment with or without Cause (other than as a result of death or Disability by providing written notice to Executive of such termination, provided however, if Orion terminates Executive’s employment for Cause, then such written notice shall indicate in reasonable detail the facts and circumstances alleged to provide a basis for such termination for Cause. If the termination is without Cause, Executive’s employment will terminate on the date specified in the written notice of termination. If the termination is for Cause, the Executive shall have thirty (30) days from the date the written notice is provided, or such longer period as Orion may determine to be appropriate, to cure any conduct or act, if curable (as determined by Orion), alleged to provide grounds for termination of Executive’s employment for Cause. If the alleged conduct or act constituting Cause is not curable (as determined by Orion), Executive’s employment will terminate on the date specified in the written notice of termination. If the alleged conduct or act constituting Cause is curable but Executive does not cure such conduct or act within the specified time period, Executive’s employment will terminate on the date immediately following the end of the cure period. Unless otherwise directed by Orion, from and after the date of the written notice of proposed termination, Executive shall be relieved of his duties and responsibilities and shall be considered to be on a paid leave of absence pending any final action by Orion confirming such proposed termination.

(d) Executive may terminate his employment with or without Good Reason by providing written notice of termination to Orion that indicates in reasonable detail the facts and circumstances alleged to provide a basis for such termination. If Executive is alleging a termination for Good Reason, Executive must provide written notice to Orion of the existence of the condition constituting Good Reason within ninety (90) days of the initial existence of such condition, and Orion must have a period of at least thirty (30) days following receipt of such notice to cure such condition.

5. Payments upon Termination.

(a) Entitlement to Severance. Subject to the other terms and conditions of this Agreement, Executive shall be entitled to the Accrued Benefits, and to the Severance Payment described in subsection (c), in either of the following circumstances while this Agreement is in effect:

(i) Executive’s employment is terminated by Orion without Cause, except in the case of death or Disability; or

(ii) Executive terminates his employment with Orion for Good Reason.

If Executive dies after receiving a notice by Orion that Executive is being terminated without Cause, or after providing notice of termination for Good Reason, the Executive’s estate, heirs and beneficiaries shall be entitled to the Accrued Benefits and the Severance Payment described in subsection (c) at the same time such amounts would have been paid or benefits provided to Executive had he lived. Any non-renewal by Orion pursuant to Section 1 or expiration of the term of this Agreement pursuant to Section 4(e) shall not constitute a termination of Executive’s employment under this Section 5(a) and Executive shall not be entitled to any amounts set forth in Section 5(c). Any non-renewal by Executive of this Agreement pursuant to Section 1 shall constitute a resignation by Executive without Good Reason and Executive shall not be entitled to any amounts set forth in Section 5(c).

(b) General Release Requirement. Executive will not be eligible to receive any payments or benefits under Section 5(c) until (i) Executive executes a general release of all claims arising out of his employment with, and termination of employment from, Orion in the form proscribed by and acceptable to Orion (“General Release”); and (ii) the revocation period specified in such General Release expires without such Executive exercising his right of revocation as set forth in the General Release.

(c) Severance Payment; Timing and Form of Severance Payment. Subject to Section 5(b) and the limitations imposed by Section 6 (and any repayment obligations under Sections 3(b) or 3(c)), in lieu of any severance pay or benefits under any Orion severance pay plans, programs or policies, if Executive is entitled to severance benefits, then Orion shall pay Executive the Severance Payment on a ratable basis each month over the eighteen (18) month period following the Termination Date, or if later, the date on which the General Release is no longer revocable, or if later, the date on which the amount payable under Section 6 is determined. All Severance Payments shall be subject to payroll taxes and other withholdings in accordance with Orion’s standard payroll practices and applicable law.

(d) Other Termination of Employment. If Executive’s employment terminates for any reason other than those described in subsection (a), Executive (or Executive’s estate in the event of his death), shall be entitled to receive only the Accrued Benefits.

9

6. Limitations on Severance Payments and Benefits. Notwithstanding any other provision of this Agreement, if any portion of the Severance Payment or any other payment under this Agreement, or under any other agreement with or plan of Orion (in the aggregate “Total Payments”), would constitute an “excess parachute payment,” then the Total Payments to be made to Executive shall be reduced such that the value of the aggregate Total Payments that Executive is entitled to receive shall be One Dollar ($1) less than the maximum amount which Executive may receive without becoming subject to the tax imposed by Code Section 4999 or which Orion may pay without loss of deduction under Code Section 280G(a); provided that the foregoing reduction in the amount of Total Payments shall not apply if the After-Tax Value to Executive of the Total Payments prior to reduction in accordance herewith is greater than the After-Tax Value to Executive if Total Payments are reduced in accordance herewith. For purposes of this Agreement, the terms “excess parachute payment” and “parachute payments” shall have the meanings assigned to them in Code Section 280G, and such “parachute payments” shall be valued as provided therein.

Within twenty (20) business days following delivery of the notice of termination or notice by Orion to Executive of its belief that there is a payment or benefit due Executive that will result in an excess parachute payment as defined in Code Section 280G, Executive and Orion, at Orion’s expense, shall obtain the opinion (which need not be unqualified) of nationally recognized tax counsel selected by Orion’s independent auditors and acceptable to Executive in Executive’s sole discretion, which opinion sets forth: (A) the amount of the Executive’s “annualized includible compensation for the base period” as defined in Code Section 280G(d)(1), (B) the amount and present value of Total Payments, (C) the amount and present value of any excess parachute payments without regard to the limitations of this Section 6, (D) the After-Tax Value of the Total Payments if the reduction in Total Payments contemplated under this Section 6 did not apply, and (E) the After-Tax Value of the Total Payments taking into account the reduction in Total Payments contemplated under this Section 6. For purposes of determining the After-Tax Value of Total Payments, Executive shall be deemed to pay federal income taxes and employment taxes at the highest marginal rate of federal income and employment taxation in the calendar year in which the Termination Payment is to be made and state and local income taxes at the highest marginal rates of taxation in the state and locality of Executive’s domicile for income tax purposes on the date the Termination Payment is to be made, net of the maximum reduction in federal income taxes that may be obtained from deduction of such state and local taxes. Such opinion shall be binding upon Orion and Executive.

Any reduction in payments and/or benefits required by this Section will occur in the following order: (I) reduction of cash payments; (II) reduction of vesting acceleration of equity awards; and (III) reduction of other benefits paid or provided to Executive. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant for Executive’s equity awards. If two or more equity awards are granted on the same date, each award will be reduced on a pro-rata basis. In no event will Executive exercise any discretion with respect to the ordering of any reductions of payments or benefits under this Section 6.

7. Covenants by Executive.

(a) Nondisclosure of Third Party Confidential Information. During Executive’s employment with Orion and after the Termination Date, Executive shall not

10

use or disclose Third Party Confidential Information for as long as the relevant third party has required Orion to maintain its confidentiality, or for so long as required by applicable law, whichever period is longer. This prohibition does not prohibit Executive’s use of general skills and know-how acquired during and prior to employment by Orion, as long as such use does not involve the use or disclosure of Third Party Confidential Information. This prohibition also does not prohibit the description by Executive of Executive’s employment history and duties, for work search or other purposes, as long as such use does not involve the use or disclosure of Third Party Confidential Information.

(b) Non-disclosure of Trade Secrets. During employment and after the Termination Date, Executive shall not use or disclose Orion’s Trade Secrets so long as they remain Trade Secrets. Nothing in this Agreement shall limit either Executive’s statutory and other duties not to use or disclose Orion’s Trade Secrets, or Orion’s remedies in the event Executive uses or discloses Orion’s Trade Secrets.

(c) Obligations Not to Disclose or Use Confidential Information. Except as set forth herein or as expressly authorized in writing on behalf of Orion, Executive agrees that while Executive is employed by Orion and during the two (2) year period commencing at the Termination Date, Executive will not use or disclose (except in discharging Executive’s job duties with Orion) any Confidential Information, whether such Confidential Information is in Executive’s memory or it is set forth electronically, in writing or other form. This prohibition does not prohibit Executive’s disclosure of information after it ceases to meet the definition of “Confidential Information,” or Executive’s use of general skills and know-how acquired during and prior to employment by Orion, so long as such use does not involve the use or disclosure of Confidential Information; nor does this prohibition restrict Executive from providing prospective employers with an employment history or description of Executive’s duties with Orion, so long as Executive does not use or disclose Confidential Information. Notwithstanding the foregoing, if Executive learns information in the course of employment with Orion which is subject to a law governing confidentiality or non-disclosure, Executive shall keep such information confidential for so long as required by law, or for two (2) years after the Termination Date, whichever period is longer.

(d) Return of Property; No Copying or Transfer of Documents. All equipment, books, records, papers, notes, catalogs, compilations of information, data bases, correspondence, recordings, stored data (including data or files that exist on any personal computer or other electronic storage device), software, and any physical items, including copies and duplicates, that Executive generates or develops or which come into Executive’s possession or control, which relate directly or indirectly to, or are a part of Orion’s (or its customers’) business matters, whether of a public nature or not, shall be and remain the property of Orion, and Executive shall deliver all such materials and items, and any and all copies of them, to Orion on the Termination Date. During employment or after the Termination Date, Executive will not copy, duplicate, or otherwise reproduce, or permit copying, duplicating, or reproduction of Orion documents or writings, whether stored on paper, magnetic tape, CD, electronically, or otherwise, including but not limited to notes, notebooks, letters, blueprints, manuals, drawings, sketches, specifications, formulas, financial documents, business plans, and the like, or any other documentation owned or originated by Orion and relating to Orion’s business

11

which, from time to time, may have come into Executive’s possession, custody, or control as a result of or in the course of Executive’s employment with Orion, without the express written consent of Orion, or, as a part of Executive’s duties performed hereunder for the benefit of Orion. Executive expressly covenants and warrants, upon termination of employment for any reason (or no reason), that Executive shall promptly deliver to Orion any and all originals and copies in Executive’s possession, custody, or control of any and all said property, documents or writings, and that Executive shall not make, retain, or transfer to any third party any copies thereof. In the event any Confidential Information or Trade Secrets are stored or otherwise kept in or on a computer hard drive or other storage device owned by or otherwise in the possession or control of Executive (collectively, “Executive Storage Device”), upon the Termination Date, Executive will present to Orion for inspection and removal of all information regarding Orion (including but not limited to Confidential Information or Trade Secrets) stored on any Executive Storage Device.

(e) Duty of Loyalty. During employment with Orion, Executive shall owe Orion an undivided duty of loyalty, and shall take no action adverse to that duty of loyalty. Executive’s duty of loyalty to Orion includes but is not limited to a duty to promptly disclose to Orion any information that might cause Orion to take or refrain from taking any action, or which otherwise might cause Orion to alter its behavior. Without limiting the generality of the foregoing, Executive shall promptly notify Orion at any time that Executive decides to terminate employment with Orion or enter into competition with Orion, as Orion may decide at such time to limit, suspend, or terminate Executive’s employment or access to one or more Companies’ Confidential Information, Trade Secrets, or customer relationships.

For eighteen (18) months following the Termination Date, for whatever reason, Executive shall not perform Services as part of or in support of the business of designing, testing, developing or producing Competing Products for sale in the Restricted Territory.

(l) Non-solicitation of Key Employees. For eighteen (18) months following the Termination Date, for whatever reason, Executive shall not, without the prior written consent of Orion, solicit a Key Employee to engage in competition with Orion, unless such Key Employee has already ceased employment with Orion. This shall not bar any Employee of Orion from applying for or accepting employment with any person or entity.

(m) Disclosure and Assignment to Orion of Inventions and Innovations.

(i) Executive agrees to disclose and assign to Orion as Orion’s exclusive property, all inventions and technical or business innovations, including but not limited to all patentable and copyrightable subject matter (collectively, the “Innovations”) developed, authored or conceived by Executive solely or jointly with others during the period of Executive’s employment, including during Executive’s employment prior to the date of this Agreement, (1) that are along the lines of the business, work or investigations of Orion to which Executive’s employment relates or as to which Executive may receive information due to Executive’s employment with Orion, or (2) that result from or are suggested by any work which Executive may do for Orion or (3) that are otherwise made through the use of Orion time, facilities or materials. To the extent any of the Innovations is copyrightable, each such Innovation shall be considered a “work for hire.”

(ii) Executive agrees to execute all necessary papers and otherwise provide proper assistance (at Orion’s expense), during and subsequent to Executive’s employment, to enable Orion to obtain for itself or its nominees, all right, title, and interest in and to patents, copyrights, trademarks or other legal protection for such Innovations in any and all countries.

(iii) Executive agrees to make and maintain for Orion adequate and current written records of all such Innovations;

(iv) Upon any termination of Executive’s employment, employee agrees to deliver to Orion promptly all items which belong to Orion or which by their nature are for the use of Orion employees only, including, without limitation, all written and other materials which are of a secret or confidential nature relating to the business of Orion.

(v) In the event Orion is unable for any reason whatsoever to secure Executive’s signature to any lawful and necessary documents required, including those necessary for the assignment of, application for, or prosecution of any United States or foreign application for letters patent or copyright for any Innovation, Executive hereby irrevocably designates and appoints Orion and its duly authorized officers and agents as Executive’s agent and attorney-in-fact, to

13

act for and in Executive’s behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the assignment, prosecution, and issuance of letters patent or registration of copyright thereon with the same legal force and effect as if executed by Executive. Executive hereby waives and quitclaims to Orion any and all claims, of any nature whatsoever, which Executive may now have or may hereafter have for infringement of any patent or copyright resulting from any such application.

(n) Remedies Not Exclusive. In the event that Executive breaches any terms of this Section 7, Executive acknowledges and agrees that said breach may result in the immediate and irreparable harm to the business and goodwill of Orion and that damages, if any, and remedies of law for such breach may be inadequate and indeterminable. Orion, upon Executive’s breach of this Section 7, shall therefore be entitled (in addition to and without limiting any other remedies that Orion may seek under this Agreement or otherwise at law or in equity) to (1) seek from any court of competent jurisdiction equitable relief by way of temporary or permanent injunction and without being required to post a bond, to restrain any violation of this Section 7, and for such further relief as the court may deem just or proper in law or equity, and (2) in the event that Orion shall prevail, its reasonable attorney’s fees and costs and other expenses in enforcing its rights under this Section 7.

(o) Severability of Provisions. If any restriction, limitation, or provision of this Section 7 is deemed to be unreasonable, onerous, or unduly restrictive by a court of competent jurisdiction, it shall not be stricken in its entirety and held totally void and unenforceable, but shall remain effective to the maximum extent possible within the bounds of the law. If any phrase, clause or provision of this Section 7 is declared invalid or unenforceable by a court of competent jurisdiction, such phrase, clause, or provision shall be deemed severed from this Section 7, but will not affect any other provision of this Section 7, which shall otherwise remain in full force and effect. The provisions of this Section 7 are each declared to be separate and distinct covenants by Executive.

(p) Definition of “Orion” for Purposes of Section 7 of this Agreement. With respect to Section 7(a) through (l) of this Agreement only, the term “Orion” shall be deemed to include Orion and other affiliates of Orion for which Employee has provided services during the prior twelve months.

8. Notice. Any notice, request, demand or other communication required or permitted herein will be deemed to be properly given when personally served in writing or when deposited in the United States mail, postage prepaid, addressed to Executive at the address appearing at the end of this Agreement and to Orion with attention to the Chief Executive Officer of Orion. Either party may change its address by written notice in accordance with this paragraph.

9. Set Off. Orion’s obligation to pay Executive any amounts and to provide any of the benefits hereunder shall be subject to set-off, counterclaim or recoupment of amounts owed by Executive to Orion.

10. Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective executors, administrators, successors and

14

assigns. Orion will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of Orion to assume expressly and agree to perform this Agreement in the same manner and to the same extent that Orion would be required to perform it if no such succession had taken place. As used in this Agreement, “Orion” shall mean Orion as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise.

11. Arbitration. Any controversy or claim arising out of or relating to this Agreement or the breach of this Agreement that cannot be mutually resolved by the Executive and Orion, including any dispute as to the calculation of the Executive’s Accrued Benefits, Base Salary, bonus amount or any Severance Payment hereunder, shall be submitted to arbitration in Milwaukee, Wisconsin, in accordance with the procedures of the American Arbitration Association. The determination of the arbitrator shall be conclusive and binding on Orion and the Executive, and judgment may be entered on the arbitrator’s award in any court having jurisdiction. Notwithstanding the foregoing, both Executive and Orion may seek to obtain injunctive relief in a Wisconsin court of competent jurisdiction pending arbitration.

12. Applicable Law and Jurisdiction. This Agreement is to be governed by and construed under the laws of the United States and of the State of Wisconsin without resort to Wisconsin’s choice of law rules. Each party hereby agrees that the forum and venue for any legal or equitable action or proceeding arising out of, or in connection with, this Agreement will lie in the appropriate federal or state courts in the State of Wisconsin and specifically waives any and all objections to such jurisdiction and venue.

13. Section 409A Compliance. This Agreement is intended to comply with, or otherwise be exempt from, Section 409A of the Code (“Section 409A”). Orion shall undertake to administer, interpret, and construe this Agreement in a manner that does not result in the imposition to the Executive of additional taxes or interest under Section 409A of the Code. If a payment obligation under this Agreement arises on account of the Executive’s Separation from Service while the Executive is a “specified employee” (as defined under Section 409A of the Code and determined in good faith by the Board), any payment of “deferred compensation” (as defined under Treasury Regulation Section 1.409A-1(b)(1), after giving effect to the exemptions in Treasury Regulation Sections 1.409A-1(b)(3) through (b)(12)) that is scheduled to be paid within six (6) months after such Separation from Service shall accrue without interest and shall be paid within fifteen (15) days after the end of the six-month period beginning on the date of such separation from service or, if earlier, within fifteen (15) days after the appointment of the personal representative or executor of the Executive’s estate following his death.

14. Captions and Paragraph Headings. Captions and paragraph headings used herein are for convenience only and are not a part of this Agreement and will not be used in construing it.

15. Invalid Provisions. Subject to Section 7(e), should any provision of this Agreement for any reason be declared invalid, void, or unenforceable by a court of competent jurisdiction, the validity and binding effect of any remaining portion will not be affected, and the remaining portions of this Agreement will remain in full force and effect as if this Agreement had been executed with said provision eliminated.

15

16. No Waiver. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

17. Entire Agreement. This Agreement contains the entire agreement of the parties with respect to the subject matter of this Agreement and supersedes any and all other agreements, either oral or in writing, between the parties hereto with respect to the employment of Executive by Orion. Each party to this Agreement acknowledges that no representations, inducements, promises, or agreements, oral or otherwise, have been made by any party, or anyone acting on behalf of any party, which are not embodied herein, and that no other agreement, statement, or promise not contained in this Agreement will be valid or binding.

18. Modification. This Agreement may not be modified or amended by oral agreement, but only by an agreement in writing signed by Orion and Executive.

19. Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

WHEREAS, this Agreement is effective as of the Effective Date set forth above.
