Exhibit 10.4 Incentive Stock Option Agreement




ADVANCED ENERGY INDUSTRIES, INC.
2008 OMNIBUS INCENTIVE PLAN


INCENTIVE STOCK OPTION AGREEMENT




Advanced Energy Industries, a Delaware corporation (the “Company”), hereby grants an option to purchase shares of its common stock, $0.001 par value, (the “Stock”) to the optionee named below. Additional terms and conditions of the grant are set forth in this Agreement, the Notice of Option Grant (the “Notice”), and in the Company’s 2008 Omnibus Incentive Plan (the “Plan”). 


Attachment 


This is not a stock certificate or a negotiable instrument.




	
			
	Incentive Stock Option 


	 
	This option is intended to be an incentive stock option under Section 422 of the Internal Revenue Code and will be interpreted accordingly. If you cease to be an employee of the Company, its parent or a subsidiary (“Employee”) but continue to provide Service, this option will be deemed a nonstatutory stock option three months after you cease to be an Employee. In addition, to the extent that all or part of this option exceeds the $100,000 rule of section 422(d) of the Internal Revenue Code, this option or the lesser excess part will be deemed to be a nonstatutory stock option. 



	Vesting 


	 
	This option is only exercisable before it expires and then only with respect to the vested portion of the option. Subject to the preceding sentence, you may exercise this option, in whole or in part, to purchase a whole number of vested shares not less than 100 shares, unless the number of shares purchased is the total number available for purchase under the option, by following the procedures set forth in the Plan. 


No additional shares of Stock will vest after your Service has terminated for any reason. 



	Term 


	 
	Your option will expire in any event at the close of business at Company headquarters on the day before the 10th anniversary of the Grant Date, as shown on the cover sheet. Your option will expire earlier if your Service terminates, as described below. 



	Regular Termination 


	 
	If your Service terminates for any reason, other than death, Disability, Cause or Retirement, then your option will expire at the close of business at Company headquarters on the 90th day after your termination date.



	Termination for Cause 


	 
	If your Service is terminated for Cause, then you shall immediately forfeit all rights to your option and the option shall immediately expire.







1






	
			
	Death 


	 
	If your Service terminates because of your death, then your option will expire at the close of business at Company headquarters on the date twelve (12) months after the date of death. During that twelve month period, your estate or heirs may exercise the vested portion of your option. 


In addition, if you die during the 90-day period described in connection with a regular termination (i.e., a termination of your Service not on account of your death, Disability, Cause or Retirement), and a vested portion of your option has not yet been exercised, then your option will instead expire on the date twelve (12) months after your termination date. In such a case, during the period following your death up to the date twelve (12) months after your termination date, your estate or heirs may exercise the vested portion of your option. 





	Disability 


	 
	If your Service terminates because of your Disability, then your option will expire at the close of business at Company headquarters on the date twelve (12) months after your termination date. 



	Retirement 


	 
	If your Service terminates because of your Retirement (as defined below), then your option will expire at the close of business at Company headquarters on the date thirty-six (36) months after your termination date. 


“Retirement” shall mean your voluntary termination after having attained age sixty (60) and having earned five (5) years or more of continuous Service. 



	Leaves of Absence 


	 
	For purposes of this option, your Service does not terminate when you go on a bona fide employee leave of absence that was approved by the Company in writing, if the terms of the leave provide for continued Service crediting, or when continued Service crediting is required by applicable law. However, your Service will be treated as terminating 90 days after you went on employee leave, unless your right to return to active work is guaranteed by law or by a contract. Your Service terminates in any event when the approved leave ends unless you immediately return to active employee work. 


The Company determines, in its sole discretion, which leaves count for this purpose, and when your Service terminates for all purposes under the Plan. 



	Notice of Exercise 


	 
	When you wish to exercise this option, you must notify the Company by filing the proper “Notice of Exercise” form at the address given on the form. Your notice must specify how many shares you wish to purchase (in a parcel of at least 100 shares generally). Your notice must also specify how your shares of Stock should be registered (e.g. in your name only or in your and your spouse’s names as joint tenants with right of survivorship). The notice will be effective when it is received by the Company. 


If someone else wants to exercise this option after your death, that person must prove to the Company’s satisfaction that he or she is entitled to do so.

	Form of Payment 


	 
	When you submit your notice of exercise, you must include payment of the option price for the shares you are purchasing. Payment may be made in one (or a combination) of the following forms: 


•    Cash, your personal check, a cashier’s check, a money order or another cash equivalent acceptable to the Company. 
•    Shares of Stock which have already been owned by you and which are surrendered to the Company.  The value of the shares, determined as of the effective date of the option exercise, will be applied to the option price. 
•    By delivery (on a form prescribed by the Company) of an irrevocable direction to a licensed securities broker acceptable to the Company to sell Stock and to deliver all or part of the sale proceeds to the Company in payment of the aggregate option price and any withholding taxes. 


If you are a resident of China you must pay the exercise price through the immediate sale of shares acquired through exercise and remitting to the Company a sufficient portion of the proceeds to pay the aggregate exercise price and tax withholding. 



	Withholding Taxes 


	 
	You will not be allowed to exercise this option unless you make acceptable arrangements to pay any withholding or other taxes that may be due as a result of the option exercise or sale of Stock acquired under this option. In the event that the Company determines that any federal, state, local or foreign tax or withholding payment is required relating to the exercise or sale of shares arising from this grant, the Company shall have the right to require such payments from you, or withhold such amounts from other payments due to you from the Company or any Affiliate.  Subject to the prior approval of the Company, which may be withheld by the Company, in its sole discretion, you may elect to satisfy this withholding obligation, in whole or in part, by causing the Company to withhold shares of Stock otherwise issuable to you or by delivering to the Company shares of Stock already owned by you. The shares of Stock so delivered or withheld must have an aggregate Fair Market Value equal to the withholding obligation and may not be subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements. 



	Corporate Transaction 


	 
	Notwithstanding the vesting schedule set forth above, upon the consummation of a Corporate Transaction, this option will become 100% vested if it is not assumed, or equivalent options are not substituted for the options, by the Company or its successor. Notwithstanding any other provision in this Agreement, if assumed or substituted for, the option will expire one year after the date of termination. 







3






	
			
	Transfer of Option 


	 
	During your lifetime, only you (or, in the event of your legal incapacity or incompetency, your guardian or legal representative) may exercise the option. You cannot transfer or assign this option. For instance, you may not sell this option or use it as security for a loan. If you attempt to do any of these things, this option will immediately become invalid. You may, however, dispose of this option in your will or it may be transferred upon your death by the laws of descent and distribution. 


Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your spouse, nor is the Company obligated to recognize your spouse’s interest in your option in any other way. 



	Retention Rights 


	 
	Neither your option nor this Agreement gives you the right to be retained by the Company (or any parent, Subsidiaries or Affiliates) in any capacity. The Company (and any parent, Subsidiaries or Affiliates) reserve the right to terminate your Service at any time and for any reason. 



	Shareholder Rights 


	 
	You, or your estate or heirs, have no rights as a shareholder of the Company until a certificate for your option’s shares has been issued (or an appropriate book entry has been made). No adjustments are made for dividends or other rights if the applicable record date occurs before your stock certificate is issued (or an appropriate book entry has been made), except as described in the Plan. 



	Forfeiture of Rights 


	 
	If during your term of Service you should take actions in competition with the Company, the Company shall have the right to cause a forfeiture of your rights, including, but not limited to, the right to cause: (i) a forfeiture of any outstanding option, and (ii) with respect to the period commencing twelve (12) months prior to your termination of Service with the Company and ending twelve (12) months following such termination of Service (A) a forfeiture of any gain recognized by you upon the exercise of an 
option or (B) a forfeiture of any Stock acquired by you upon the exercise of an option (but the Company will pay you the option price without interest). Unless otherwise specified in an employment or other agreement between the Company and you, you take actions in competition with the Company if you directly or indirectly, own, manage, operate, join or control, or participate in the ownership, management, operation or control of, or are a proprietor, director, officer, stockholder, member, partner or an employee or agent of, or a consultant to any business, firm, corporation, partnership or other entity which competes with any business in which the Company or any of its Affiliates is engaged during your employment or other relationship with the Company or its Affiliates or at the time of your termination of Service. Under the prior sentence, ownership of less than 1% of the securities of a 
public company shall not be treated as an action in competition with the Company.

	Adjustments 


	 
	In the event of a stock split, a stock dividend or a similar change in the Stock, the number of shares covered by this option and the option price per share shall be adjusted (and rounded down to the nearest whole number) pursuant to the Plan. Your option shall be subject to the terms of the agreement of merger, liquidation or reorganization in the event the Company is subject to such corporate activity in accordance with the terms of the Plan. 



	Applicable Law 


	 
	This Agreement will be interpreted and enforced under the laws of the State of Colorado, other than any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.



	The Plan 


	 
	The text of the Plan is incorporated in this Agreement by reference. 


This Agreement and the Plan constitute the entire understanding between you and the Company regarding this option. Any prior agreements, commitments or negotiations concerning this option are superseded. 



	Data Privacy 


	 
	In order to administer the Plan, the Company may process personal data about you. Such data includes but is not limited to the information provided in this Agreement and any changes thereto, other appropriate personal and financial data about you such as home address and business addresses and other contact information, payroll information and any other information that might be deemed appropriate by the Company to facilitate the administration of the Plan. 


By accepting this option, you give explicit consent to the Company to process any such personal data. You also give explicit consent to the Company to transfer any such personal data outside the country in which you work or are employed, including, with respect to non-U.S. resident Optionees, to the United States, to transferees who shall include the Company and other persons who are designated by the Company to administer the Plan. 



	Consent to Electronic Delivery 


	 
	The Company may choose to deliver certain statutory materials relating to the Plan in electronic form. By accepting this option grant you agree that the Company may deliver the Plan prospectus and the Company’s annual report to you in an electronic format. If at any time you would prefer to receive paper copies of these documents, as you are entitled to, the Company would be pleased to provide copies. Please contact the Company’s Stock Plan Administrator to request paper copies of these documents. 



	Certain Dispositions 


	 
	If you sell or otherwise dispose of Stock acquired pursuant to the exercise of this option sooner than the one year anniversary of the date you acquired the Stock, then you agree to notify the Company in writing of the date of sale or disposition, the number of shares of Stock sold or disposed of and the sale price per share within 30 days of such sale or disposition. 







5






	
			
	Immediate Sale of Shares for Residents of China 


	 
	Upon the exercise of this option, if you are a resident of China, you shall authorize and direct a broker to immediately sell any and all shares that otherwise would have been delivered, net of applicable taxes and exercise consideration due the Company. This Agreement shall serve as your express authorization to sell immediately any and all shares acquired upon the exercise of this option. As soon as reasonably practical, you shall be entitled to payment of the proceeds resulting from such disposition, net of the applicable tax withholding and exercise consideration due to the Company. 








By accepting this Agreement, you agree to all of the terms and conditions described above and in the Plan.
