YIT Corporation ("YIT") in accordance with the merger plan and approved the
merger plan. Pursuant to the merger plan, Lemminkäinen shall be merged into YIT

new shares of YIT for each share owned in Lemminkäinen, that is, the merger
consideration shall be issued to the shareholders of Lemminkäinen in proportion
to their existing shareholding with a ratio of 3.6146:1. In case the number of
shares received by a shareholder of Lemminkäinen as merger consideration would
be a fractional number, the fractions shall be rounded down to the nearest whole
number. Fractional entitlements to new shares of YIT shall be aggregated and
sold in public trading on Nasdaq Helsinki Ltd. and the proceeds will be
distributed to Lemminkäinen’s shareholders being entitled to receive such
fractional entitlements in proportion to holding of such fractional
entitlements. Any costs related to the sale and distribution of fractional
entitlements shall be borne by YIT. The total number of shares issued as merger
consideration shall be rounded down to the nearest full share.

Shareholders representing 10.6 per cent of all shares and votes in Lemminkäinen
voted against the merger resolution and demanded redemption of their shares in
Lemminkäinen.

IMPORTANT NOTICE

Notice to Lemminkäinen Shareholders in the United States

The YIT shares to be issued in connection with the merger have not been
registered under the U.S. Securities Act of 1933, as amended (the "Securities
Act") and are being issued in reliance on the exemption from registration set
forth in Rule 802 under the Securities Act.

YIT and Lemminkäinen are Finnish companies and the issuance of YIT shares will
be subject to procedural and disclosure requirements in Finland that may be
different from those of the United States. Any financial statements or other
financial information included in this release may have been prepared in
accordance with non-U.S. accounting standards that may not be comparable to the
financial statements of U.S. companies or companies whose financial statements
are prepared in accordance with generally accepted accounting principles in the
United States.

It may be difficult for U.S. shareholders of Lemminkäinen to enforce their
rights and any claims they may have arising under U.S. federal securities laws
in connection with the merger, since YIT and Lemminkäinen are located in non
-U.S. jurisdictions, and some or all of YIT's and Lemminkäinen's officers and
directors may be residents of countries other than the United States. As a
result, U.S. shareholders of Lemminkäinen may not be able to sue YIT or
Lemminkäinen or their respective officers and directors in a court in Finland
for violations of U.S. federal securities laws. Further, it may be difficult to
compel YIT or Lemminkäinen to subject themselves to the jurisdiction or judgment
of a U.S. court.

Lemminkäinen’s shareholders should be aware that YIT may purchase Lemminkäinen’s
shares otherwise than under the merger, such as in open market or privately
negotiated purchases, at any time during the pendency of the proposed merger.

Notice to Shareholders in the European Economic Area

The English language offering circular has been prepared on the basis that any
offer of the merger consideration shares in any Member State of the European
Economic Area ("EEA") other than offers (the "Permitted Public Offers") which
are made prior to the Effective Date (as defined in the English language
offering circular), and which are contemplated in the English language offering
circular in Finland once the Finnish language merger prospectus has been
approved by the competent authority in Finland and published in accordance with
the Prospectus Directive, and in respect of which YIT has consented in writing
to the use of the English language offering circular, will be made pursuant to
an exemption under the Prospectus Directive from the requirement to publish a
prospectus for offers of the merger consideration shares. Accordingly any person
making or intending to make an offer in that Member State of the merger
consideration shares which are the subject of the offer contemplated in the
English language offering circular, other than the Permitted Public Offers, may
only do so in circumstances in which no obligation arises for YIT to publish a
prospectus pursuant to Article 3 of the Prospectus Directive or supplement a
prospectus pursuant to Article 16 of the Prospectus Directive, in each case, in
relation to such offer. YIT has not authorised, nor does it authorise, the
making of any offer (other than Permitted Public Offers) of the merger
consideration shares in circumstances in which an obligation arises for YIT to
publish or supplement a prospectus for such offer.

In relation to each Member State of the EEA, with effect from and including the
date on which the Prospectus Directive was implemented in that Member State (the
"Relevant Implementation Date") no offer has been made and will not be made
(other than a Permitted Public Offer) of the merger consideration shares which
are the subject of the offering contemplated by the English language offering
circular to the public in that Member State, except that, with effect from and
including the Relevant Implementation Date, an offer of such merger
consideration shares is made to the public in that Member State:

a) to any legal entity which is a qualified investor as defined in the
Prospectus Directive;

b) to fewer than 150 natural or legal persons (other than qualified investors as
defined in the Prospectus Directive), as permitted under the Prospectus
Directive, subject to obtaining the prior consent of YIT for any such offer; or

c) in any other circumstances falling within Article 3(2) of the Prospectus
Directive,

provided that no offer of the merger consideration shares is made which would
require YIT to publish a prospectus pursuant to Article 3 of the Prospectus
Directive or supplement a prospectus pursuant to Article 16 of the Prospectus
Directive.

The expression an offer of the merger consideration shares to the public in
relation to any merger consideration shares in any Member State means the
communication in any form and by any means of sufficient information on the
terms of the offer and the merger consideration shares to be offered so as to
enable an investor to decide to purchase or subscribe to the merger
consideration shares, as the same may be varied in that Member State by any
measure implementing the Prospectus Directive in that Member State.

The expression "Prospectus Directive" means Directive 2003/71/EC (as amended),
and includes any relevant implementing measure in the EEA Member State
concerned.
