It is clarified that the Offeror belongs to the LafargeHolcim group of companies and submits the present Tender Offer as a result of the respective obligation arisen on the ultimate parent undertaking, LafargeHolcim Ltd, which acts in concert with the Offeror.

3. As a result to the above change in the ultimate indirect control of the Company, which triggers the obligation to submit a mandatory tender offer pursuant to Article 7 of the Law, the Offeror initiated the Tender Offer process on 30/07/2015 (the "Tender Offer Date"), informing the Hellenic Capital Market Commission (the "HCMC") and the Company's Board of Directors and submitting to the said bodies the draft Prospectus, pursuant to Article 10 of the Law.

4. As of 10/07/2015 and on the Tender Offer Date, the Offeror held 63,253,403 Shares in the Company, which represent circa 88.99% of the total paid-up share capital and voting rights of the Company.

5. Through the Tender Offer, the Offeror undertakes to acquire the sum of the Company's Shares which it did not hold, directly or indirectly, on 10/07/2015 . Accordingly, the shares that are the subject of the Tender Offer stand at 7,829,304 Shares, equivalent to 11.01% of the paid-up share capital and voting rights of the Company (the "Shares of the Tender Offer").

6. Pursuant to Article 9 of the Law, the Offeror offers € 1.23 for each Share of the Tender Offer validly tendered (the "Offer Price"), which amounts to the average weighted trading price of the shares of the Company during the last six (6) months prior to the date on which the Offeror was obliged to submit the Tender Offer, i.e. before 10/07/2015 .

It is noted that the relevant tax on stock exchange transactions, which today equals to 0.20% on the value of the over the counter transaction for the transfer of the Shares to the Offeror will be deducted from the payable Offer P rice. The transaction value on which the 0.20% sales tax will be applied will be the higher between the Offer Price and the closing price at ATHEX as at the date before the date of application for the transfer of the S hares to the Hellenic Central Securities Depository( " ATHEXCSD ") .

It is also noted that the Offeror shall undertake to pay the ATHEXCSD clearing fees, equaling 0.08% on the value of the shares transferred, which is calculated as the product of the number of shares to be transferred multiplied by the highest of the following prices: the Offer Price and the closing price of the share at the ATHEX on the day preceding the submission of the requisite documents of article 46 of the Dematerialized Securities System Regulation to the ATHEXCSD, with minimum charge amount equal to the lowest between €20 and the 20% of the value of the shares transferred per each Shareholder that will validly accept the Tender Offer (the " Accepting Shareholder " ), pursuant to article 7 of the codified decision 1/223/28.1.2014 of the Board of Directors of ATHEXCSD, as currently in force.

Consequently, the Accepting Shareholders will collect the Tender Offer amount per share without the deduction of the above fees but reduced to the amount of the aforementioned tax.
