INDIRECTLY, IN THE U.S. OR ANY OTHER JURISDICTION WHERE PUBLICATION,
ANNOUNCEMENT OR DISTRIBUTION OF THE INFORMATION DOES NOT COMPLY WITH APPLICABLE
LAW.
STOCKHOLM, April 29, 2015 – The Board of Karo Bio AB (publ) has resolved to
carry out a rights issue with preferential rights for the existing shareholders.
The terms of the rights issue entail that three (3) existing shares will entitle
to subscription for one (1) new share at a subscription price of SEK 1.00.
Subscription for new shares shall take place during the period from June 3, 2015
up to and including June 18, 2015. At full subscription, Karo Bio will be
provided with rights issue proceeds amounting to approximately MSEK 230 before
rights issue costs. In addition, it is proposed that the meeting authorize the
Board to resolve on an over-allotment option of MSEK 20 to be utilized in the
event of a large interest and an over-subscription of the rights issue. The
rights issue is covered to 100% by subscription undertakings and guarantee
undertakings, of which more than 95% is guaranteed by Anders Lönner, Chairman of
the Board.

The rights issue resolution of the Board is subject to the approval of the
meeting and therefore the shareholders are summoned to an Extraordinary General
Meeting to be held on May 25, 2015. Notice of Extraordinary General Meeting will
be announced in a separate press release.

Background and reasons

Since the year-end Pfizer is developing the RORgamma-project towards the market.
Karo Bio is entitled to compensation of more than MUSD 200, exclusively of
royalties, when the project reaches certain development and sales goals, As
regards the ERbeta cancer and ERbeta MS projects, work is focused on finding
potential partners for licensing.

The new direction of Karo Bio is to create a balance between pre-clinical
projects and more projects and products closer to the market. The first step of
this new direction was taken by the agreement concluded in March on marketing co
-operation with the German pharmaceutical company Dr. Wolff. In April, Karo Bio
acquired the development company Tanomed AB which develops a unique product for
soothing and preventing common colds through strengthening of the body’s own
defense to fight coriza virus. This means that Karo Bio has added two new
business projects during the first quarter.

The ambition is to add more projects during 2015 and onwards in order to
continue the expansion of the company’s development portfolio by investing in
innovative projects with a low development risk and short time to the market
that enables new products. In this area, there are in Sweden as well as abroad,
a large number of interesting development projects where Karo Bio, with its new
organisation and international network and experience within the company, can
contribute to creating a surplus value.

The company evaluates several acquisition possibilities. This offensive strategy
may result in some financial undertakings but will in the end lead to an
increased shareholder value.

In order to strengthen the company’s financial and operational capacity, the
Board of Karo Bio has resolved to carry out a rights issue.

Terms of the rights issue
The rights issue entails that Karo Bio’s share capital is increased by maximum
of SEK 4,598,244.337097 through the issue of maximum 229,914,516 shares.
Existing shareholders have preferential rights to subscribe for new shares in
proportion to the number of shares previously owned. Those who are registered as
shareholders of Karo Bio at the record date are entitled to subscribe for one
(1) new share for each three (3) existing shares in the company.

The record date for the determination of which shareholders are entitled to
subscribe for new shares with preferential rights shall be June 1, 2015.
Subscription for new shares shall take place during the period from June 3, 2015
up to and including June 18, 2015, or such later date to be decided by the
Board. The subscription price for each new share shall be SEK 1.00, which means
that the new issue, at full subscription, will provide rights issue proceeds of
approximately MSEK 212 after rights issue costs.

In the event that not all shares are subscribed for by the exercise of
subscription rights, the Board shall decide on allotment of shares without the
exercise of subscription rights up to the maximum amount of the rights issue.
Such allotment shall be made, firstly, to those who have subscribed for shares
by exercising subscription rights and who wish to subscribe for additional
shares, pro rata in proportion to their subscription by exercising subscription
rights, secondly, to others who have notified their interest to subscribe for
shares without exercising subscription rights, pro rata in proportion to their
subscription and, thirdly, to those who have guaranteed subscription for shares
pro rata in proportion to provided guarantees.

Over-allotment option
In addition, it is proposed that the meeting authorize the Board to resolve on
an over-allotment option of additionally maximum 20,000,000 shares at a
subscription price of SEK 1.00 per share to be exercised at a large interest and
at full subscription of the rights issue. If fully exercised, Karo Bio is
provided with additional rights issue proceeds of MSEK 20. The new share issue
may take place without preferential rights of the company’s shareholders
according to the principles of allotment applicable to the rights issue.

Subscription and guarantee undertakings
Anders Lönner and Nomic AB (represented by Per-Anders Johansson, board member),
who jointly represent approximately 7.0 per cent of the share capital of Karo
Bio, have undertaken to subscribe for their full pro rata shares in the rights
issue, which corresponds to approximately MSEK 16 of the rights issue. In
addition to the subscription undertaking, Anders Lönner has undertaken to
subscribe for shares in the total amount of MSEK 214 in the rights issue. In
total, approximately MSEK 230 in the rights issue is secured by subscription
undertakings and guarantees undertakings equivalent to 100% of the total rights
issue amount.
