ARTICLE IV

RIGHTS RELATING TO THE DEPOSITED SECURITIES, CERTAIN OBLIGATIONS OF THE CUSTODIAN

SECTION 4.01. Fixing of Record Date. Whenever any cash dividend or other cash distribution shall become payable or any distribution other than cash shall be made, or whenever rights shall be issued, with respect to the Deposited Securities, or whenever, for any reason, the Company causes a change in the number of Shares or other Deposited Securities that are represented by each SDR or any exchange of SDRs is effected, the Company shall, with the prior written consent from the Custodian (which shall not be unreasonably withheld) and in accordance with applicable laws, decide upon a record date (“Record Date”) which shall be applied by the Custodian for the determination of the Holders who are entitled to receive cash dividend or other property, distribution of rights or the net proceeds of the sale thereof, to receive Shares in connection with bonus issues and to otherwise exercise those rights which normally inure to shareholders in the Company.

In conjunction with every distribution of dividends, the Company and the Custodian shall determine the date for the payment of dividends (“Payment Date”). It is the Company’s and the Custodian´s intention, where practically feasible and otherwise appropriate, that the Record Date in Sweden for dividends and other rights in accordance with the above shall correspond to the record date for shareholders of the Company as provided by Luxembourg law and/or the Articles of Association of the Company.

The Custodian shall notify Euroclear Sweden of any Record Date at least five (5) Business Days in advance of such date, provided that routines in accordance with Euroclear Sweden´s rules and regulations from time to time are applicable for

payment of dividend in cash. In the case of a distribution of any kind to Holders, including dividends in cash, where such routines with Euroclear Sweden mentioned above are not applicable, the Custodian shall notify Euroclear Sweden of the Payment Date of such distribution, at least 40 Business Days in advance of such date. In addition, the Custodian shall supply Euroclear Sweden with any further information it requires in connection with any distributions in accordance with the VPC Agreement.

SECTION 4.02. Cash Distributions. Whenever the Custodian, receives any cash dividend or other cash distribution by the Company on any Deposited Securities, the Custodian shall, as promptly as practicable prior to payment taking place, convert or cause such dividend or distribution received by the Custodian, to be converted into SEK in accordance with Section 4.06 and such amount shall on the Payment Date determined by the Company and the Custodian be distributed through Euroclear Sweden to the Holders registered in the VPC Register on Record Date as entitled pursuant to Section 4.01 or other holders of the right to the dividend, in proportion to the number of SDRs representing such Deposited Securities held by them respectively; provided, however, that in the event that the Company, Euroclear Sweden, the Custodian or the Registrar shall be required to withhold and do withhold, subject to Section 4.10 hereof, from any cash dividend or other cash distribution in respect of any Shares an amount on account of taxes or other governmental charges, the amount distributed to the Holder in respect of SDRs representing such Shares shall be reduced accordingly. Dividend amounts for each SDR will be payable in SEK rounded down to SEK 0,01 and any balance not so distributable shall be repaid by the Custodian to the Company.

The Company shall notify the Custodian of the gross amount of the cash dividend or distribution per Share in EURO in accordance with Section 4.01.

SECTION 4.03. Distributions in Shares/Bonus Issues. If any distribution upon any Shares consists of a dividend in, or free bonus distribution of, Shares, (excluding any such distribution where a Holder is given the option to receive cash in lieu of Shares) the Company shall, with the prior written consent from the Custodian (which shall not be unreasonably withheld), determine the manner in which such dividend shall be provided to the Holders. The Custodian shall arrange to adjust the VPC Register to reflect such increase in the aggregate number of SDRs representing such Shares; provided, however, that if for any reason (including any requirement involving that the Company, Euroclear Sweden or the Custodian must withhold an amount on account of taxes or other governmental charges in order for the dividend to be distributed to Holders and Beneficial Owners of SDRs) the Custodian, in its reasonable judgment, after consent from the Company which shall not be unreasonably withheld, deems such distribution not to be feasible, the Custodian and the Company may adopt such method, if any is available, as they may agree is equitable, practicable and in accordance with market practice for the purpose of effecting such distribution. Such methods include the advance payment of any taxes or governmental charges or the sale (a public or private sale) of the Shares to be distributed, or any part thereof, and the net proceeds of any such sale, following deduction for sales costs and taxes, shall be distributed by the Custodian, through Euroclear Sweden, to the Holders entitled thereto as in the case of a distribution received in cash. In the event that Euroclear Sweden or the Custodian shall be required to withhold, and do withhold any taxes or governmental charges subject to Section 4.10 hereof, from any such distribution, the amount distributed to the Holder shall be reduced accordingly. If any Holder is entitled to receive fractional Shares as a result of a distribution of a dividend in, or free bonus distribution of, Shares, the Custodian shall promptly sell such fractional Shares and shall distribute the proceeds of such sale to the Holders entitled thereto as promptly as practicable.

SECTION 4.04. New issue of Shares etc. In the event that the Company decides on a new issue of Shares, issuance of convertible debentures, warrants or other rights to the shareholders, the Custodian shall inform the Holders thereof and of the principal terms and conditions for such issue. The Custodian shall procure that the rights to subscribe for additional Shares, convertible debentures, warrants or other rights are distributed and offered to the Holders as soon as possible. Alternatively,

the Company and the Custodian may agree, to the extent permitted by the General Terms and Conditions, that the Custodian instead shall offer to the Holders that they shall instruct the Custodian to subscribe for such Shares, convertible debentures, warrants or other rights on behalf of Holders. When the Custodian has subscribed for and received such Shares, convertible debentures, warrants or other rights in accordance with the instructions of the Holder, the Custodian shall, to the extent practically possible, procure that the corresponding registration is effected to the credit of the VPC Account of the Holder. If by the terms of such rights offering, including if such financial instruments or rights would not be dematerialized electronically, or by reason of applicable law, the Custodian may not, or is unable to, make such rights available to such Holders, the Custodian and the Company may agree, if they deem that to be a method that is equitable, practicable and in accordance with market practice, that the Custodian shall dispose of such rights and make the net proceeds available to such Holders, or employ such other method as it may deem feasible in order to facilitate the exercise, sale or transfer of rights by such Holders.

SECTION 4.05. Cash/Share Alternative Distributions and Distributions Other Than Cash, Shares or Rights. Whenever the Custodian shall receive any distribution other than cash, Shares or rights upon any Deposited Securities, including a distribution whereby the Holders are offered the option of receiving either cash or securities, the Custodian shall cause such cash, securities or property to be distributed to the Holders entitled thereto, as promptly as practicable, in proportion to the number of SDRs representing such Deposited Securities held by them respectively, in any manner that the Custodian shall decide; provided, however, that, if the Custodian cannot cause such cash, securities or property to be distributed or such distribution cannot be made proportionately among the Holders entitled thereto, or if for any other reason (including any requirement involving that Euroclear Sweden or the Custodian must withhold an amount on account of taxes or other governmental charges in order for the dividend to be distributed to Holders) the Custodian deems, after consent from the Company which shall not be unreasonably withheld, such distribution not to be feasible, the Custodian and the Company may adopt such method, if any be available, that is equitable, practicable and in accordance with market practice for the purpose of effecting such distribution, including the sale (a public or private sale) of the securities or property thus received, or any part thereof, and the net proceeds of any such sale shall be distributed by the Custodian to the Holders entitled thereto as in the case of a distribution received in cash and any unsold balance of such securities or property shall be distributed by the Custodian to the Holders entitled thereto. In the event that Euroclear Sweden or the Custodian shall be required to withhold, and does withhold, any taxes or governmental charges subject to Section 4.10 hereof, from any such distribution, the amount distributed to the Holder shall be reduced accordingly.

SECTION 4.06. Conversion of Foreign Currency. If the Custodian receives foreign currency, by way of dividends or other distributions or the net proceeds from the sale of securities, property or rights, the Custodian shall convert the funds received into SEK. In such event, the Custodian shall use its best efforts to obtain the best exchange rate, in the reasonable opinion of the Custodian, and shall, if practically possible, consult the Company before executing the conversion.

SECTION 4.07. Voting of Deposited Securities. The Company shall inform the Custodian of any shareholders’ meeting to be held in the Company as soon as a date for a shareholders’ meeting has been resolved by the board of directors. As regards annual shareholders’ meetings, the Company shall inform the Custodian no later than two (2) months in advance of such meeting and as regards any extraordinary shareholders meetings, the Company shall inform the Custodian as soon as practically possible and prudent. The Company further undertakes to inform the Custodian of tentatively planned shareholders’ meetings if the Company, in its sole discretion, deems it appropriate to disclose such information.

The Company shall, in consultation with the Custodian, within any time period prescribed by Luxembourg and other laws applicable to the Company, inform the Holders of any shareholders´ meeting to be held in the Company. The information

shall be published in accordance with the General Terms and Conditions, and such publication shall include (i) the contents set forth in the notice from the Company of the shareholders´ meeting, (ii) instructions regarding any measures to be taken by the Holder in order to authorise a proxy holder to exercise any rights attached to the Shares which are represented by SDRs and (iii) instructions regarding any measures to be taken by the Holder to be able to attend the shareholders´ meeting. The Company and the Custodian shall before any shareholders’ meeting in consultation and in accordance with applicable laws agree on a record date to be applied by Custodian for determining which Holders are entitled to participate in the proceedings of and to vote at general meetings of shareholders. Only Holders which are registered in the VPC Register on such record date may exercise the rights mentioned in (ii) and (iii) above. On the record date, the Custodian will report the preliminary results of their tabulation of attendance to the Company which shall be subject to further rectification to be notified by the Custodian as soon as practically possible but at the latest 3 Business Days after the record date or another date as agreed between the Custodian and the Company. In no event may such rectifications mean that the Custodian accept notices to attend a general meeting which was not received on or before the record date.

The Company shall at all times publish notices of shareholders´ meetings in accordance with Luxembourg law and other applicable rules and regulations.

Well in advance of the shareholders’ meetings, the Custodian undertakes to make arrangements so that proxies, with full power of substitution, are issued by the Custodian to each Holder who has announced his or her intention to participate in the proceedings of the shareholders meetings to allow each of them to represent the Custodian at the shareholders meetings for the number of Shares represented by the SDRs held by each Holder. Furthermore, the Custodian and the Company undertake to make arrangements so that proxies are available to each Holder who has announced his or her intention to participate in the proceedings of the shareholders meetings to allow each of them to designate a third party as attorney to represent him or her at the shareholders meetings. Such proxies received by the Custodian shall be submitted to the Company together with a list of Holders to whom proxies have been issued by the Custodian no later than one (1) Business Day prior to the shareholders meeting.

The Custodian undertakes not to represent Shares for which the Holder has not notified its intention to participate or vote at such shareholders´ meeting either personally or by proxy. The Custodian shall not itself exercise any voting discretion over any Shares.

SECTION 4.08. Changes Affecting Deposited Securities. Upon any change in par value, split-up, consolidation or any other reclassification of Shares, or upon any recapitalization, reorganization, merger or consolidation, or sale of assets affecting the Company or to which it is a party, any securities or property that shall be received by the Custodian in exchange for, or in conversion, replacement or otherwise in respect of, Deposited Securities shall be treated as new Deposited Securities under this Custodian Agreement, and the SDRs shall, subject to the terms of this Custodian Agreement, the General Terms and Conditions and applicable laws thereafter represent the new Deposited Securities so received in exchange or conversion. The Custodian shall cause appropriate adjustments to be made in the records of Euroclear Sweden in respect of the number of SDRs issued, as in case of a stock dividend on the Shares, to reflect SDRs representing such new Deposited Securities.

Immediately upon the occurrence of any such change, conversion or exchange covered by this Section 4.08 in respect of the Shares, the Custodian shall provide notice thereof in writing, as supplied by the Company, to be given to all Holders.

Notwithstanding the foregoing, in the event that any security so received may not be lawfully distributed to all Holders, the Custodian and the Company may agree, if they deem that to be equitable, practicable and in accordance with market practice, that the Custodian shall sell such securities (a public or private sale), at such place or places and upon such terms as

the Company and the Custodian may deem proper, and may allocate the net proceeds of such sales for the account of the Holders otherwise entitled to such securities upon an averaged or other practicable basis and distribute the net proceeds so allocated to the extent practicable as in the case of a distribution received in cash.

SECTION 4.09. Transmittal of Company Notices, Reports and Communications. On or before the first date on which the Company gives notice, by publication or otherwise, of any meeting of holders of Shares or of any adjourned meeting of such holders, or of the taking of any action by such holders of Shares other than at a meeting, or of the taking of any action in respect of any cash or other distribution or offering of any rights in respect of the Shares, the Company will transmit to the Custodian and Euroclear Sweden a copy of the notice thereof in the form given or to be given to holders of Shares in English unless the Company deems, in each individual case, a translation of a document into Swedish to be appropriate due to the contents or the purpose of the document.
