Current board members Gunnar Brock, Sune Carlsson, Börje Ekholm, Sirkka Hämäläinen, Grace Reksten Skaugen, O. Griffith Sexton, Lena Treschow Torell, Jacob Wallenberg and Peter Wallenberg Jr were re-elected. Board Member Håkan Mogren had declined re-election.

Getinge AB, Meda AB, The Confederation of Swedish Enterprise and The Strategic Research Foundation, and Member of The Center for Molecular Medicine and The Swedish Corporate Governance Board. The Meeting re-elected Jacob Wallenberg as Chairman of the Board. Compensation to the Board of Directors The Meeting approved the compensation to the Board for 2010 totaling 7,312,500 Swedish kronor, which will be divided, in cash and in so-called synthetic shares, as follows: unchanged 1,875,000 Swedish kronor to the Chairman, unchanged 500,000 Swedish kronor to the other nine members of the Board not employed in the company, and a total of 937,500 Swedish kronor in cash for work in the committees of the Board. The Meeting approved that at least 25 percent and maximum 50 percent of gross remuneration before taxes, excluding fees for committee work, shall be paid through allocation of synthetic shares. Each synthetic share shall after five years entitle to payment of an amount corresponding to the stock market price of a share of class B in the company at the date of payment. Due to administrative reasons, board members with foreign tax domicile shall be entitled to receive 100 percent of their remuneration in cash. Thus, not less than SEK 1,218,750 and not more than SEK 3,187,500 of remuneration to the Board shall consist of synthetic shares. The number of synthetic shares allocated shall be based on the market price of Investor shares of class B in connection with the day when the share is traded without the right to receive dividend. Vesting of the synthetic shares is granted, with 25 percent at each occasion, after the publications of each of the year-end report and the three interim reports, respectively, during the term of office. Payment occurs after the publications of the year-end report and the three interim reports, respectively, during the fifth year following the general meeting which resolved on the allocation of the synthetic shares, with 25 percent of the allocated synthetic shares on each occasion. The financial effect for the Company, if Members of the Board receive part of their remuneration in synthetic shares compared to receiving the full remuneration in cash, is due to the hedging arrangements, assessed to be very limited. Amendment of the Articles of Association The Meeting approved the Board of Directors’ proposal regarding the amendment of the Articles of Association in respect of notice of a General Meeting of shareholders, entailing that notice shall be published in the Official Swedish Gazette (Post- och Inrikes Tidningar) as well as at the Company’s website, and information that the notice has been issued shall be published in Dagens Nyheter and in Svenska Dagbladet. The amendment is conditional upon that the provisions of the Companies Act (2005:551) regarding notice to general meeting will be amended. Guidelines for Salary and Other Remuneration The Meeting approved the Board of Directors’ proposal regarding guidelines for salary and other remuneration for the President and other Members of Management Group for 2010. Long-term Variable Remuneration Program The Meeting approved the scope and key principles of the long-term variable remuneration program for the Management Group and other employees for 2010, consisting of a Stock Matching Plan and a Performance Share Program. According to the Stock Matching Plan all employees will, for each Investor share (“Participation Share”) which they acquire at market price during a certain period, to be determined by the Board, after the Meeting 2010, after a three-year vesting period, receive two options (“Matching Options”) and the right to purchase one Investor share (“Matching Share”). The Matching Share can be acquired for SEK 10 during a four-year period after the vesting period. During the same period, each Matching Option entitles the holder to purchase one Investor share of class B at an exercise price corresponding to 120 per cent of the average volume weighted price of the share of class B during the mentioned measurement period. The theoretical value of the Stock Matching Plan has been calculated considering the value of the options, the investment risk, the risk that the employment ends and the price paid for every Matching Share. At an estimated stock price of SEK 120 the calculated value amounts to approximately 88 per cent of the amount the employee invests in Investor shares. According to the Performance Share Program, Senior Management, after a three-year vesting period, has the right during four years to acquire Investor shares (“Performance Shares”) for a price per share corresponding to the price the Senior Management has paid for a Participation Share (the “Acquisition Price”). The average annual total return of the Investor share (including reinvested dividends) must exceed the interest on 10-year government bonds with more than 10 percentage points in order for Senior Management to be entitled to acquire the maximum number of Performance Shares, which supposedly has been allotted to the respective Senior Manager. If the total return does not exceed the 10-years interest on government bonds with at least 2 percentage points, then Senior Management is not entitled to acquire any shares. If the total return is between the 10-years interest on government bonds plus 2 percentage points and the 10-years interest on government bonds plus 10 percentage points, then a proportional (linear) calculation of the number of shares that may be acquired shall be made. The theoretical value of a Performance Share considers, inter alia, the likelihood for meeting the performance criteria and is based on the Black & Scholes valuation model. At an estimated stock price of SEK 120, the value of every Performance Share amounts to SEK 16. The likelihood, calculated based on historical data (verified by external advisors), to meet the performance criteria has then been calculated to nearly 50 per cent. Assuming a stock price of SEK 120 during the Measurement Period the highest number of shares which can be acquired by the employees as a result of the Matching Options will be 360,000. The highest number of Matching Shares that the employees can have the right to acquire, including estimated remuneration for dividends, amounts to 235,000. The highest number of Performance Shares that Senior Management can have the right to acquire, including estimated remuneration for dividends, amounts to 1,385,000. The highest number of shares that can be acquired under the long-term variable remuneration is, in order to maintain the value given above, dependent upon the stock price for the Investor share over the measurement period and can thus increase or decrease. The cost for the 2010 long-term variable remuneration program amounts, with a stock price of SEK 120 for the shares during the measurement period, to approximately SEK 31 million for the Stock Matching Plan and approximately SEK 23 million for the Performance Share Program. Estimated costs for social security charges are included in these amounts. Purchase and Transfer of the Company’s Own Shares The Meeting authorized the Board, for the time until the annual general meeting of 2011, to decide on the purchase and transfer of the company’s own shares, in order to give the Board wider freedom of action in their work with the company’s capital structure, to enable transfer of own shares according to item 17B, and to secure the costs, including the social security payments, in connection with the long-term variable remuneration program and with the allocation of synthetic shares as part of the remuneration to the Board of Directors. The authorization may be used to purchase at the most so many shares that the Company’s holding of own shares after the purchase amounts to a maximum of one-tenth of all the shares in the Company. Purchases may be effected on NASDAQ OMX Stockholm at a price within the registered price interval from time to time. Purchases may also be effected in accordance with a purchase offer directed to all shareholders for a consideration in the form of cash, whereby the deviation at the most may be 20 percent in relation to the current stock price, and or for a consideration of shares in other companies than Investor, whereby a deviation of the stock market price may be as the Board finds appropriate. Transfer of shares may also be effected at a price in cash or value of property received which corresponds to the market price at the time of the transfer of the Investor shares transferred with such deviation as the Board finds appropriate. The Meeting resolved that transfer of acquired shares of class B in the company shall be possible to holders under the long-term variable remuneration program 2010, in accordance with the terms and conditions set out above. A maximum of 2,700,000 shares or the higher number that may follow from a recalculation because of a split, bonus issue or similar action may be transferred. As per April 14, 2010, the Company is holder of 4,683,800 shares of class B. Nomination Committee The Meeting approved the proposal for the Nomination Committee.
