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 18 – Resolutions on a reduction of the share capital through cancellation
of treasury shares and increase of the share capital by bonus issue
A. Reduction of the share capital through cancellation of treasury shares

The board of directors proposes a reduction of the company’s share capital of
SEK 4,141,137.50 through cancellation of 3,394,375 shares, without reimbursement
to the shareholders. The purpose of the reduction is to transfer the amount by
which the share capital is reduced to a fund where it can be used as
unrestricted equity. The reduction will be made through cancellation of
3,394,375 shares acquired by the company following board decisions authorized at
the annual general meeting 2012.

The board of directors, or a person appointed by the board, shall be authorized
to implement any minor adjustments to the Meeting’s resolution that may be
necessary in connection with registration with the Swedish Companies
Registration Office and Euroclear. 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. The resolution is also
conditional upon the Meeting resolves to approve the board’s proposal under item
B below.

B. Increase of the share capital by bonus issue

The board of directors proposes that the Meeting decides to increase the
company’s share capital through a bonus issue in accordance with the following.
The bonus issue will increase the share capital with SEK 4,191,679.80, without
the issue of new shares. The purpose of the bonus issue is to restore the share
capital after the reduction effected in accordance with item A above, rounded
up, to obtain the desired quota value for the company. The company’s share
capital will be increased through a transfer from unrestricted equity.

The board of directors, or a person appointed by the board, shall be authorized
to implement any minor adjustments to the Meeting’s resolution that may be
necessary in connection with registration with the Swedish Companies
Registration Office and Euroclear. The resolution is conditional upon the
Meeting resolves to approve the board’s proposal under item A above.

Item 19 - 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 2014, 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 shareholders shall retain their preferential rights
if the board of directors resolves to issue new shares against cash
contribution. 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 6,900,000 shares, in the aggregate (assuming full conversion of
the convertibles and before any re-calculations according to the conditions of
the convertibles). Directed 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 9.9 per cent of the share capital
and the votes, subject to that the Meeting resolves in favour of the proposal to
cancel re-purchased shares as proposed under Item 18.

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 20 - 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 annual general meeting 2014.
2.    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. Number of transferred shares may not exceed the
shares actually held by the company at time of the board’s resolution to
transfer the shares.
3.     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.
