To take part in the General Shareholders' Meetings on May 13, 2014, shareholders must follow the procedures described below:

• 1) Only people who are Solvay SA shareholders on April 29, 2014 at midnight (Belgium time) (hereafter called the registration date) will have the right to participate and vote in the General Shareholders' Meetings on May 14, 2013, regardless of the number of shares held by the shareholder the day of the meetings.
• 2) Holders of registered shares who wish to participate in the meetings will not have to follow specific procedures to register their shares. The registration of their shares will ensue from their enrollment on the SOLVAY SA shareholder register on the registration date. They will, however, have to give notice of their desire to attend the meetings by returning the participation notice attached to the convening

notice; it must be received by Solvay SA no later than May 7, 2014 and can be returned either by regular mail to the address of the corporate headquarters, or by fax or by electronic mail.

Holders of registered shares who wish to be represented at the meetings will also have to return the completed and signed proxy form attached to this convening notice; it must be received by Solvay SA no later than May 7, 2014 either by regular mail to the address of the corporate headquarters or by fax or by electronic mail.

The shareholders who have declared their desire to participate in the meetings and have returned a proxy form may attend the meetings in person, but without being able to vote since their votes by proxy will have been counted in advance.

3) Holders of dematerialized shares who wish to participate in the meetings must request a statement from the authorized account holder or from the settlement organization that holds their share account stating the number of dematerialized shares registered in their name in the books of these institutions on the registration date and for which they have declared a desire to participate in the meetings. This statement will have to be received by Solvay SA no later than May 7, 2014, and sent by regular mail to the address of Solvay's corporate headquarters, or by fax or by electronic mail.

The holders of dematerialized shares who wish to be represented by proxy at the meetings will also have to return a completed and signed proxy form to be received by Solvay SA no later than May 7, 2014 either by regular mail to the address of Solvay's corporate headquarters, or by fax or by electronic mail.

The proxy from is available at the corporate headquarters, on the Internet site and at the following financial establishments: BNP Paribas Fortis, ING and KBC.

The shareholders who have declared their desire to participate in the meetings, by returning their proxy form, can attend the meetings in person, but without, however, being allowed to vote since their votes by proxy will have been counted in advance.

• 4) The designated proxy holder does not necessarily have to be a SOLVAY SA shareholder. The appointment of the proxy holder must be done with special consideration to avoid potential conflicts of interest between the shareholders and the proxy holder (see article 547bis §4 of the Code of Companies). This clause is aimed particularly at the Chairman of the General Shareholders' Meetings, the members of the Board of Directors, the members of the Executive Committee and generally the employees of SOLVAY SA, their spouses or legal partners and their relatives.
• 5) Under some conditions, one (or more) shareholder(s) holding (together) at least 3% of the share capital may request the addition of new items to the agendas and/or submit new motions for a resolution. Solvay SA should receive these requests no later than April 18, 2014, sent either by regular mail to the address of its corporate headquarters, or by fax or by electronic mail. Should certain shareholders exercise this right, Solvay SA will send, no later than April 28, 2014, to shareholders by regular mail a final agenda and a completed proxy form and will also make thee documents available on the Internet site.

Shareholders who have complied with the instructions for admission to the meetings may also submit questions in writing to the Board of Directors regarding items on the agendas or its reports, as well as to the External Auditor with regard to his report. These questions must reach Solvay SA no later than May 7, 2014 and be sent either by regular mail to its corporate headquarters or by fax or by electronic mail.

Upon presentation of a statement by an authorized account holder or a settlement organization certifying the number of dematerialized shares registered in the name of the shareholder, each

shareholder can obtain a free copy of all the documents related to the meeting on May 13, 2014, either at the corporate headquarters or with the financial organizations mentioned above. All of these documents are also available on the Internet site of Solvay SA.

• 6) Motions for resolution or comments from the Board of Directors on the agenda items that do not require motions are also available on the Solvay Internet site.
• 7) It should be noted that the motions for resolutions will be submitted for electronic vote. Proxy votes will be counted in advance and systematically integrated into each point. It should be recalled that one share is equal to one vote.

It should be noted that if you are also a Solvac shareholder, you will be required to carry out the procedure for signing of attendance lists for Solvay and Solvac only one time. You will receive only one mailbox for the meetings of both companies as well as a single smart card showing, totally separated, the number of votes corresponding to the portfolio of shares involved. This is done for your convenience and simplification.

8) Please note that the signatures on the attendance list will begin being accepted as of 9:00 a.m. on May 13
