The variable compensation is maximized to 70% of base salary for the Group President, 50% for Business Area Presidents and 40% for other members of Group Management.  The Board now proposes a performance related personnel option program for 2006 in accordance with b) below.  Pension premium is paid in compliance with a contribution based plan with premiums ranging between 25-35% of base salary depending on age. In addition, the Group President is entitled to a health pension amounting to 50% of his base salary.  Other benefits consist of company car, according to normal standard, and health insurance.  A mutual termination period of six months shall apply. Termination compensation can maximum amount to 24 months base salary.  The proposal is available with the company and on the internet homepage www.atlascopco.com/agm and will also be sent free of charge to the shareholder who so requests.  b) a performance related personnel option program for 2006  Background and reasons for the proposal  The Board considers it to be important, and it is in the interest of the shareholders, that key personnel in Atlas Copco have a long term interest in a good development of the value of the shares of the company and that they align their work efforts to foster such a development. In addition, it is the opinion of the Board that a share related option program increases Atlas Copco's attractiveness as employer on the global market and enhances the possibility to recruit and keep key personnel in the Group Scope and main principles  Granting  The Board has the right to decide on the granting of personnel options that can give maximum 220 key personnel in the Group the possibility to acquire maximum 1 600 000 Atlas Copco series A-shares.  The granting of options depends on the development of the value growth of the Group, expressed as Economic Value Added (EVA), during 2006. In an interval of MSEK 600 the granting varies linear from zero to 100% of the maximum grant. The size and span of the interval are established by the Board and are in compliance with the long range plan goals of the Group.  The granting of personnel options is maximized to the following number of persons within the different key groups:  Category 1 - the Group President - 50 000 personnel options  Category 2 - business area Presidents (3) - 25 000 personnel options  Category 3 - other members of the Group Management and division Presidents (approx 25) - 12 500 personnel options  Category 4 - other key persons (approx 175) - 6 250 personnel options  The Board will make a decision regarding the persons that shall be included in the above stated categories based upon position, qualification and individual performance. The granting of personnel options will take place not later than during March 2007.  The Board has the right to decide to implement an alternative incentive solution for key persons in such countries where the granting of personnel options is not feasible. Such an alternative incentive solution shall, to the extent practically possible, be established on terms corresponding to those of the personnel option programme. Term of the personnel options  The term of the personnel options shall be five years from the date of granting. The personnel options are non-transferable and vesting requires continued employment. Exercise price  The exercise price shall be established to an amount corresponding to 110% of the average of the closing prices at the Stockholm stock exchange for series A-shares during a period of 10 trading days next following the date of the publishing of the year end communiqué for the business year 2006. Delivery of shares and costs  The personnel options shall give the right to acquire issued shares. The personnel option program will thus not result in any dilution of the number of shares or votes in the company. In order to reduce the economic risk in connection with an increase of the share value during the term of the personnel options and in order to secure the delivery of shares in accordance with the personnel option agreements to be entered into, the Board intends to secure this undertaking through one or more financial institutions. Other  For a decision in compliance with the proposal of the Board, supporting votes from shareholders representing more than half of the votes cast are required.  The complete proposal of the Board under this item is available with the company and on the internet homepage www.atlascopco.com/agm not later than April 12, 2006. The complete proposal will also be sent free of charge to the shareholder who so requests.  Item 17 -The Board's proposal regarding changes of the Articles of Association  The Board proposes that the Articles of Association is changed for the purpose of deleting all references that were introduced at the Annual General Meeting 2005 regarding Series C-shares and redemption and in order to align the Articles to the provisions of the new corporate law. The proposal of the Board as to the latter primarily means that the provisions regarding nominal value of the shares is replaced with provisions regarding the highest and lowest number of shares, that the shareholders shall have right of first refusal also in case of issue of shares based on set-off and to subscription options and convertibles in connection with cash issue or set-off issue, that notice shall be given by public advertising in the Official Gazette and Dagens Nyheter and in addition encompasses certain changes of formal and editorial nature.  The Board also proposes that the General Meeting decides that the President is authorized to make such minor adjustments in the decisions under this Item 17 that turn out to be required in connection with the registration at the Company Registration Office (Bolagsverket).  For a decision in compliance with the proposals from the Board under this Item 17 it is required that the decision of the General Meeting is supported by shareholders who represent at least 2/3 of both the votes given and the number of shares represented at the meeting.  The proposal is available with the company and on the internet homepage www.atlascopco.com/agm and will also be sent free of charge to the shareholder who so requests.  Item 18 - The Board's proposal regarding purchase of own shares  The Board proposes that the General Meeting decides as follows.  That the Board is authorized to, until the next Annual General Meeting, decide on the purchase of shares in the company at one or more occasions in compliance with the following.  1. Purchase can maximum be made of the number of Series A or Series B shares or a combination thereof that the number of shares held by the company after each purchase does not exceed 10% of the total number of shares in the company  2. The shares can only be purchased on the Stockholm stock exchange  3. The purchase of shares on the Stockholm stock exchange can only be made at a price per share that falls within the registered price range at each given time  The intention with the purchase is to continuously be able to adapt the capital structure of the company and thereby add to an increased shareholder value. Purchased shares are intended to be declared invalid on the proposal from the Board at a later General Meeting. Currently the company does not own any of its own shares.  For a decision in compliance with the proposals from the Board under this Item 18 it is required that the decision of the General Meeting is supported by shareholders who represent at least 2/3 of both the votes given and the number of shares represented at the meeting.  The proposal is available with the company and on the internet homepage www.atlascopco.com/agm and will also be sent free of charge to the shareholder who so requests. Audited accounts  The annual report will be available on the internet homepage www.atlascopco.com/agm from March 29, 2006.  In connection with the Annual General Meeting two awards will be granted, the ???John Munck Award??? for decisive contributions in product development and the ???Peter Wallenberg Marketing and Sales Award??? for the developing of new methods in the areas of marketing and sales.  Nacka, March 2006  The Board of Directors
