ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On August 15, 1997, Advanced Energy Industries, Inc. (the "Company") 
acquired Tower Electronics, Inc. ("Tower"), pursuant to a Share Purchase 
Agreement dated as of August 11, 1997, among the Company, Roger C. Hertel, an 
individual and the former sole shareholder of Tower ("Seller"), and Tower. 
Tower designs and manufactures custom, high performance switchmode power 
supplies that are used principally in the telecommunications, medical and 
non-impact printing industries. Tower's principal customers include U.S. 
Robotics, a subsidiary of 3Com Corporation, VideoJet Systems International, 
Inc., Medtronic and Intermedics. Tower had revenues of $13.4 million for its 
fiscal year ended September 30, 1996. The purchase price consisted of $14.5 
million in cash and a promissory note to Seller in the original principal 
amount of $1.5 million, which were delivered by the Company at closing, and 
an earn out provision, pursuant to which Seller will be entitled to 
additional consideration for his shares if Tower's sales achieve certain 
levels in 1998. The promissory note matures in August 1998 and is 
non-interest bearing. $12 million of the cash payment made at closing was 
funded by a term loan from Silicon Valley Bank and Bank of Hawaii, pursuant 
to a Loan and Security Agreement dated August 15, 1997. The acquisition will 
be accounted for using the purchase method of accounting.

     The Company intends to continue Tower's manufacturing operations out of 
Tower's existing facilities, which consist of approximately 21,000 square 
feet of leased space in Fridley, Minnesota. The Company also has retained all 
of Tower's approximately 95 full-time and approximately 25 temporary employees.
