Very truly yours,

                I have read this letter and accept the offer of employment on the terms and conditions set forth herein.

ATTACHMENT 1

I will not use or disclose during or after my employment, except as authorized by Clean Energy (“Company”) in the performance of my duties, Company Information that I have or will acquire (whether or not developed by me) during my employment by Company, its predecessor companies, and their subsidiaries or any companies, joint ventures or other operations in which Company has any interest.

The term “Company Information” as used in this Agreement means (a) information or any item of knowledge owned, acquired, or developed by Company not generally known in the relevant trade or industry, the use of which confers a competitive advantage over those that do not use or possess it including without limitation confidential information or knowledge about Company’s products, processes, services, research, exploration, reserves, engineering, manufacturing operations, computer programs, marketing, business plans, and methods of doing business; (b) other information or knowledge in Company’s possession, whether technical, business, or financial, the use or disclosure of which might reasonably be construed to be contrary to the interest of Company; and (c) information received from third parties under confidential conditions or with a restriction on use or disclosure.

I agree that upon termination of my employment for any reason I will turn over to Company all tangible embodiments of Company Information that I have in my possession and my obligations not to use or disclose Company Information will continue except that when Company Information becomes generally available to the public other than by my acts or omissions, it is no longer subject to the restrictions provision.

ATTACHMENT 2

Any controversy, dispute or claim between any employee and the Company, or its officers, agents or other employees, shall be settled by binding arbitration, at the request of either party.  The arbitrability of any controversy, dispute or claim under this policy shall be determined by application of the substantive provisions of the Federal Arbitration Act (9 U.S.C. sections 1 and 2) and by application of the procedural provisions of the California Arbitration Act.  Arbitration shall be the exclusive method for resolving any dispute; provided, however, that either party may request provisional relief from a court of competent jurisdiction, as provided in California Code of Civil Procedure Section 1281.8.

The claims which are to be arbitrated under this policy include, but are not limited to claims for wages and other compensation, claims for breach of contract (express or implied), claims for violation of public policy, wrongful termination, tort claims, claims for unlawful discrimination and/or harassment (including, but not limited to, race, religious creed, color, national origin, ancestry, physical disability, mental disability, gender identity or expression, medical condition, marital status, age, pregnancy, sex or sexual orientation ) to the extent allowed by law, and claims for violation of any federal, state, or other government law, statute, regulation, or ordinance, except for claims for workers’ compensation and unemployment insurance benefits.

The employee and the Company will select an arbitrator by mutual agreement.  If the employee and the Company are unable to agree on a neutral arbitrator, either party may elect to obtain a list of arbitrators from the Judicial Arbitration and Mediation Service, the American Arbitration Association, or any other reputable dispute resolution organization.

The demand for arbitration must be in writing and must be made by the aggrieved party within the statute of limitations period provided under applicable California and/or federal law for the particular claim.  Failure to make a written demand within the applicable statutory period constitutes a waiver to raise that claim in any forum.  Arbitration proceedings will be held in Los Angeles County, California.

The arbitrator shall apply applicable California and/or federal substantive law to determine issues of liability and damages regarding all claims to be arbitrated, and shall apply the California Evidence Code to the proceeding.  The parties shall be entitled to conduct reasonable discovery and the arbitrator shall have the authority to determine what constitutes reasonable discovery.  The arbitrator shall hear motions for summary disposition as provided in the California Code of Civil Procedure.

Within thirty days following the hearing and the submission of the matter to the arbitrator, the arbitrator shall issue a written opinion and award which shall be signed and dated.  The arbitrator’s award shall decide all issues submitted by the parties, and the arbitrator may not decide any issue not submitted.  The arbitrator shall prepare in writing and provide to the parties a decision and award which includes factual findings and the reasons upon which the decision is based.  The arbitrator shall be permitted to award only those remedies in law or equity which are requested by the parties and allowed by law.

The decision of the arbitrator shall be binding and conclusive on the parties and cannot be reviewed for error of law or legal reasoning of any kind.  Judgment upon the award rendered by the arbitrator may be entered in any court having proper jurisdiction.

The cost of the arbitrator and other incidental costs of arbitration that would not be incurred in a court proceeding shall be borne by the Company.  The parties shall each bear their own costs and attorneys’ fees in any arbitration proceeding, provided however, that the arbitrator shall have the authority to require either party to pay the costs and attorneys’ fees of the other party, as is permitted under federal or state law, as a part of any remedy that may be ordered.

Both the Company and employees understand that by using arbitration to resolve disputes they are giving up any right that they may have to a judge or jury trial with regard to all issues concerning employment.

No employee or other Company representative can modify this policy in any manner nor enter into any agreement that is contrary to this policy unless it is in writing and signed by the Chief Executive Officer.  If any term, provision, covenant or condition of this policy is held by a court of competent jurisdiction or an arbitrator to be invalid, void, or unenforceable, the remaining terms and provisions of this Policy will remain in full force and effect and shall in no way be affected, impaired, or invalidated.
