NSIG FINLAND SUPPLEMENTS THE TENDER OFFER DOCUMENT RELATING TO THE VOLUNTARY PUBLIC TENDER OFFER FOR ALL OF THE ISSUED AND OUTSTANDING SHARES AND OPTION RIGHTS IN OKMETIC

Okmetic Oyj ("Okmetic") announced on 1 April 2016 that Okmetic and National Silicon Industry Group ("NSIG") had entered into a combination agreement pursuant to which NSIG, either directly or through its subsidiary, will make a voluntary public tender offer to purchase all of the issued and outstanding shares and option rights in Okmetic that are not owned by Okmetic or any of its subsidiaries (the "Tender Offer").

NSIG Finland S.à r.l ("NSIG Finland" or the "Offeror"), a wholly-owned indirect subsidiary of NSIG, commenced the Tender Offer on 22 April 2016 and published its tender offer document relating to the Tender Offer on 21 April 2016 ("Tender Offer Document").

Pursuant to the press release of NSIG announced on 30 May 2016, NSIG Finland has declared its Tender Offer unconditional and at the same time extended the acceptance period until 14 June 2016. According to the release, due to the extension of the offer period, the Offeror has decided to amend the terms and conditions of the Tender Offer to the benefit of the shareholders and holders of option rights, to allow acceptances for the shares and option rights validly tendered in the Tender Offer to be withdrawn at any time during the extended offer period or, if the offer period has been further extended, during such further extended offer period, despite the fact that the Offeror has declared the Tender Offer unconditional and is therefore under an obligation to complete the Tender Offer.

NSIG has today 31 May 2016 announced a press release according to which the Finnish Financial Supervisory Authority has today approved a supplement to the Tender Offer Document reflecting the above amendment. The press release of NSIG in its entirety, including the supplement of the Tender Offer Document, is attached as Annex 1 to this stock exchange release.

Annex 1

SUPPLEMENT NO. 1 TO THE TENDER OFFER DOCUMENT PUBLISHED ON 21 APRIL 2016 BY NSIG FINLAND S.À R.L. RELATING TO THE VOLUNTARY PUBLIC TENDER OFFER FOR ALL OF THE ISSUED AND OUTSTANDING SHARES AND OPTION RIGHTS IN OKMETIC OYJ

31 May 2016

NSIG Finland S.à r.l. ("NSIG Finland" or the "Offeror") supplements the tender offer document published on 21 April 2016 ("Tender Offer Document") in accordance with Chapter 11, Section 11, Subsection 4 of the Finnish Securities Markets Act (746/2012, as amended) with the following information.

The initial offer period under NSIG Finland's voluntary public tender offer to purchase all of the issued and outstanding shares and option rights in Okmetic Oyj ("Okmetic") that are not owned by Okmetic or any of its subsidiaries (the "Tender Offer") expired on 27 May 2016. All the conditions to completion of the Tender Offer have been satisfied during the initial offer period and the Offeror has on 30 May 2016 declared the Tender Offer unconditional.

However, the Offeror has been informed that contrary to assessments made prior to the announcement of the Tender Offer, the relevant Ministries have indicated that due to certain technology used by Okmetic, the completion of the Tender Offer may, in their view, require approval of the Finnish Ministry of Employment and the Economy under the Act on the Monitoring of Foreign Corporate Acquisitions (172/2012). The Offeror and Okmetic have immediately taken actions to clarify the situation and aim to complete these discussions as soon as possible. The Offeror will also make any filings necessary under said Act.

In order to allow time for the above discussions, the Offeror has, pursuant to the terms and conditions of the Tender Offer, on 30 May 2016 extended the offer period to expire on 14 June 2016 at 4:00 p.m. Finnish time. Depending on the outcome of the above discussions with the relevant Ministries, the Offeror may further extend the offer period in accordance with the terms and conditions of the Tender Offer, but not beyond 30 June 2016. However, any subsequent offer period under the terms and conditions of the Tender Offer may extend beyond 30 June 2016 provided that the Offeror will timely complete the Tender Offer. Assuming that the offer period will expire on 14 June 2016, the Offeror will announce the final result of the Tender Offer on or about 17 June 2016, and settlement will take place on or about 22 June 2016. Even if the Offer Period would be further extended, the completion and the settlement of the Tender Offer would take place on or about 8 July 2016 at the latest.

Due to the extension of the offer period, the Offeror has decided to amend the terms and conditions of the Tender Offer to the benefit of the shareholders and holders of option rights, to allow acceptances for the shares and option rights validly tendered in the Tender Offer to be withdrawn at any time during the extended offer period or, if the offer period has been further extended, during such further extended offer period, despite the fact that the Offeror has declared the Tender Offer unconditional and is therefore under an obligation to complete the Tender Offer. Accordingly, the first paragraph of Section 4. "Terms and Conditions of the Tender Offer" subsection 4.7. "Withdrawal Rights" in the Tender Offer Document has been amended with respect to the extended offer period to read as follows: 

1. "The acceptances for the Shares and the Option Rights validly tendered in accordance with the terms and conditions of the Tender Offer may be withdrawn at any time during the extended Offer Period, even if the Offeror has declared Tender Offer unconditional and is therefore under an obligation to complete the Tender Offer."

Except for the changes to the withdrawal rights, the terms and conditions of the Tender Offer remain unchanged.

The Tender Offer Document with the aforementioned supplements and amendments is available as from 31 May 2016.

The Finnish Financial Supervisory Authority has approved the Finnish language version of this supplement but is not responsible for the accuracy of the information presented therein. The decision number of such approval is FIVA 7/02.05.05/2016.
