     THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”), dated as of August 5, 2008, among IPG Photonics Corporation, a Delaware corporation (the “Company”), IPG Laser GmbH, a German company (“IPGL”), and Dr. Valentin Gapontsev (“Gapontsev”) and Igor Samartsev (“Samartsev” together with Gapontsev, “Sellers” and each a “Seller”).

	I.		The Company owns 100% of IPGL, and IPGL owns a 66.0% participation interest in “Scientific and Technical Association” “IRE-Polus”, a Russian limited liability company (“IRE”).
	II.		Gapontsev and Samartsev own respectively 26.7% and 4.9% participation interests (“Interests”) in IRE.
	III.		IPGL wants to acquire all of Sellers’ Interests in IRE, and Sellers desire to exchange all of their respective Interests in IRE in exchange solely for voting shares (“Photonics Common Stock”) of the Company in a transaction (‘Transaction”) that the parties intend qualifies as a reorganization within the meaning Section 368(a)(1)(B) of the U.S. Internal Code of 1986, as amended (“Code”).
			Accordingly, each of the parties agrees as follows:

1.

TRANSFER OF INTERESTS AND ISSUANCE OF PHOTONICS COMMON STOCK

     1.1 Closing. Subject to the satisfaction or waiver of the conditions in Section 4 below, the exchange of Interests in IRE and the Photonics Common Stock shall take place in Moscow, Russia, at a place to be determined, at 4:00 p.m., on September 25, 2008 or at such other time and place as the Company and the Sellers mutually agree upon (which time and place are designated as the “Closing”). The purchase price for the Interests to be sold by Gapontsev and Samartsev are $5,169,300 and $948,673 respectively (“Purchase Price”), which shall be paid in the form of validly issued, non-assessable unregistered shares of Photonics Common Stock, valued at the closing price of the Photonics Common Stock on the third trading day after the date of this Agreement.

The parties intend that (i) the Transaction qualifies as a Section 368(a)(1)(B) reorganization, and (ii) the exchange of each of the Seller’s respective Interests for Photonics Common Stock of equivalent fair market value qualifies for tax-free treatment to each Seller under Section 354 of the Code. The parties agree that they will take no U.S. tax position inconsistent with such intended treatment. The parties agree to prepare, execute and file all

required notices and forms with the U.S. Internal Revenue Service (“IRS”) as may be necessary or advisable to order to effectuate the intent of this Section 1.2, including but not limited to forms, agreements and notices under Sections 368 and 367 of the Code and IRS regulations thereunder.
