Proposals of the board of directors

Item 10 - Resolution on the appropriation of earnings

The board of directors proposes a dividend of SEK 0.20 per share. Record date for dividend is proposed to be Tuesday, 4 May 2010. Payment of dividend is estimated to be effectuated by Euroclear Sweden AB (former VPC AB) on Friday 7 May 2010.

Item 16 – Resolution on guidelines for compensation for the executive management

The Board of Directors' proposes that the Meeting resolves to adopt guidelines for compensation for the executive management substantially in accordance with the following. The company shall strive to offer members of the executive management of the company a compensation that is adjusted to the conditions of the market. The compensation committee shall prepare and present such compensation proposals to the board of directors for resolution. In the compensation proposals the importance of the work, competence, experience and performance shall be taken into account. The compensation may consist of: fixed yearly income, variable income, pension benefits, discretionary bonus arrangements, and severance pay. The board of directors may for certain special purposes, if it is motivated by special circumstances, choose to deviate from these guidelines.

Item 17 - Resolution on authorization for the board of directors to issue shares and/or convertibles

The board of directors proposes that the Meeting adopts a resolution to authorize the board of directors to, until the annual general meeting 2011, at one or several occasions and with or without deviation from the shareholders' preferential rights, adopt resolutions to issue shares and/or convertibles. The board of directors

shall have the right to resolve that the shares and/or the convertibles shall be paid in kind or otherwise be subject to conditions referred to in Chapter 2 Section 5 second paragraph 1-3 and 5 of the Swedish Companies Act or that the shares and/or the convertibles shall be subscribed for with a right of set-off. The board of directors resolutions to issue shares and/or convertibles may result in an increase of the number of shares in the company of not more than 8,800,000 shares, in the aggregate (assuming full conversion of the convertibles and before any re-calculations according to the conditions of the convertibles). Issues may be made in order to finance acquisitions of companies or parts of companies. In case of a directed cash issue of shares, the subscription price for the new shares shall be determined in close connection with the share price for the Biotage share on the NASDAQ OMX Stockholm at the time of the issue. In case of a directed cash issue of convertibles, the pricing and conditions of the convertibles shall be in line with market conditions. Considering the above, the board of directors shall also be authorized to resolve on such other conditions that the board of directors finds necessary to carry out the issues.

The reasons for the right to deviate from the shareholders preferential rights are to enable the company to, in a quick and effective way, finance acquisitions of companies or parts of companies. In case of full exercise of the authorization, and assuming full conversion of any issued convertibles (however before any re-calculations according to the conditions of the convertibles), the dilution effect corresponds to approximately 9 per cent of the share capital and the votes.

The board of directors, or any person appointed by the board of directors, shall be authorized to make minor adjustments of the resolution adopted by the Meeting in order to fulfil the registration with the Swedish Companies Registration Office (Sw. Bolagsverket). A resolution by the Meeting to adopt the board of directors' proposal shall be valid only where shareholders holding no less than two thirds of the votes cast as well as the shares represented at the Meeting approve the resolution.

Item 18 - Resolution on authorization for the board of directors to acquire and transfer own shares The board of directors proposes that the Meeting resolves to authorize the board of directors to acquire and transfer own shares on NASDAQ OMX Stockholm substantially in accordance with following:

• 1. The authorisation may be utilised on one or more occasions, however not longer than until the 2011 annual general meeting.
• 1. The company may 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.
• 1. Acquisitions and transfers of shares may only take place at a price within the price interval at any time recorded on the NASDAQ OMX Stockholm, and this shall refer to the interval between the highest buying price and the lowest selling price.

The purpose of the proposed repurchase option is to give the board of directors wider freedom of action in the work with the company's capital structure. There is a requirement for a resolution to be passed in accordance with the board's proposal that the resolution of the meeting is supported by shareholders representing at least 2/3 of both the votes cast and of the shares represented at the meeting.
