2. SUBJECT OF THE TENDER OFFER

On 11 May 2015, the company with registered name 'Holcim Ltd' filed a public exchange offer on the shares of the company with registered name 'Lafarge S.A.', which was the ultimate parent company of the Company. Further to the completion of the above public exchange offer, Holcim Ltd acquired on 10 July 2015, a 87.46% stake in the share capital of Lafarge S.A. and on the same date, changed its registered name to LafargeHolcim Ltd. Therefore, LafargeHolcim Ltd. became on 10 July 2015 the controlling shareholder of Lafarge S.A. The public exchange offer was thereafter resumed from 15 July 2015 until 28 July 2015 and following the completion of a squeeze-out process on 23 October 2015, LafargeHolcim Ltd. acquired 100% of the share capital of Lafarge S.A.

As a result, on 10 July 2015, LafargeHolcim Ltd became the indirect owner of 63,253,403 shares in the share capital of the Company (the 'Shares'), which correspond to 88.99% of the total voting rights thereof and consequently became the ultimate parent company of the Company. It is clarified that the Offeror belongs to the LafargeHolcim group of companies and has submitted the Tender Offer as a result of the respective obligation arisen on the ultimate parent undertaking, LafargeHolcim Ltd, which acts in concert with the Offeror. The Offeror duly initiated the Tender Offer procedure on the Tender Offer Date. It is noted that from 10 July 2015 until the Information Memorandum Date there have been no other changes as to the control of the Shares and voting rights in respect of the direct shareholder of the Company, namely the Offeror, or the indirect control of the Shares and voting rights from any other entities controlled by LafargeHolcim Ltd.

In particular, on the Tender Offer Date and the Information Memorandum Date, the shares being the object of the Tender Offer amounted to 7,829,304 shares (the 'Tender Offer Shares'), which correspond to 11.01% of the voting rights of the Company.

The Offeror does not intend to acquire any further shares in the Company, through the ATHEX or otherwise, during the period from publication of the submission of the Tender Offer until the end of the Acceptance Period, as such is defined below.

3. ACCEPTANCE PERIOD

The acceptance period of the Tender Offer will commence on Wednesday, 11 November 2015 and end on Friday, 11 December 2015 (the 'Tender Offer Acceptance Period') by close of business (in accordance with the business hours followed by banks operating in Greece).

4. OFFER CONSIDERATION

In accordance with Article 9 of the Law, the Offeror will pay the amount of €1.23 in cash per Tender Offer Share in relation to which the Tender Offer will be timely and validly accepted (the 'Offer Consideration').

The Offer Consideration is fair and reasonable in accordance with Article 9 para. 4 of the Law, as specifically analyzed in section 2.12 of the Information Memorandum.

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 Consideration to any accepting shareholders.

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 ('DSS') Regulation, 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.

5. PROCEDURE OF ACCEPTANCE OF THE TENDER OFFER

Accepting Shareholders must complete and lodge a declaration of acceptance of the Tender Offer (the 'Declaration of Acceptance') at any branch of the Receiving Bank in Greece. Accepting Shareholders may also authorise the Initial Operator of their Shares Account on the DSS (as defined in the DSS Operating Rules), to take all the necessary steps for the acceptance of Tender Offer on their behalf.

The transfer of the offered shares to the Offeror and payment of the Offer Consideration to the Accepting Shareholders will take place within three business days from the announcement of the results of the Tender Offer, namely until 18 December 2015.

7. NOTES

If, following the completion of the Tender Offer, the Offeror and any persons acting in concert with the Offeror hold shares representing in aggregate at least 90% of the total voting rights of the Company, the Offeror will exercise its squeeze-out right i.e., it will require the transfer to it of all remaining shares of the Company, in accordance with Article 27 of the Law (the 'Squeeze-out Right') and decision 1/644/22.04.2013 of the Board of Directors of the CMC.

Further to the completion of the process of exercising the Squeeze-out Right, the Offeror will convene a general meeting of the shareholders of the Company in order to resolve on the delisting of the shares of the Company from ATHEX and, thereafter, will proceed with submitting a request to the CMC in connection with such delisting.

In case the requirements of article 27 of the Law are not fulfilled and, therefore, the Offeror is not entitled to the exercise of the Squeeze-out Right, the Offeror will not pursue any action towards the delisting of the shares from ATHEX.
