The issue of new shares to Johnson & Johnson consists of a private placement of 5.4 million shares of nominally DKK 1 by Genmab to JJDC registered in New Jersey.

The new shares will be issued by Genmab under the authorization to the board of directors from Genmab's shareholders granted at the annual general meeting on April 6, 2011. The new shares will be issued for cash without pre-emptive rights for Genmab's existing shareholders, and no person or entity other than JJDC will participate in the private placement.

Each share has a subscription price of DKK 88 per share of a nominal value of DKK 1 (one). Genmab's closing share price on August 29, 2012 was DKK 67.85.

The new shares have the same rights and privileges as all other shares issued by Genmab. The new shares are freely transferable negotiable instruments and will carry full rights to dividends as of the date of issue. Under the terms of the share subscription agreement, JJDC has agreed to certain customary restrictions on trading Genmab shares.

Genmab currently has 44,907,142 shares outstanding and after completion of the private placement the number of shares will be 50,307,142. After the issue of the new shares, JJDC will own 10.73% of Genmab's share capital.

A private placement prospectus containing more details of the placement is being prepared and will be published in accordance with applicable rules and regulations. The prospectus will be published as soon as possible after the signing of the share subscription agreement. The share subscription agreement is subject to customary closing conditions, including antitrust clearance of the daratumumab license agreement between Genmab and Janssen from the Federal Trade Commission and the Antitrust Division of the Department of Justice under the Hart-Scott-Rodino Act and approval of the prospectus by the Danish Financial Supervisory Authority. An application will be made for the admittance and listing of the new shares for trading on the NASDAQ OMX Copenhagen A/S.
