Full Description of Material Change
 
The Company announced on May 1, 2007 that it has signed an agreement with 6707157 Canada Inc. and an affiliate thereof to recapitalize and reorganize Lorus’ business which, if completed, will result in the addition of approximately $7.8 million in non-dilutive financing for the Company.

Under the terms of the agreement, Lorus will transfer all of its assets and liabilities and all of the shares of its subsidiaries held by it to a new company (“Newco”). Current securityholders in Lorus will exchange their securities in Lorus for equivalent securities in Newco (the “Exchange”) and the board of directors and management of Lorus will continue as the board of directors and management of Newco. Newco will change its name to Lorus Therapeutics Inc. and apply for a substitutional listing of the common shares of Newco on both the Toronto Stock Exchange (TSX) and the American Stock Exchange (AMEX). Following the transaction, Newco will continue to carry on the business carried on by Lorus but will have the benefit of the non-dilutive financing.
 
 

 

In connection with the transaction and after the Exchange, the share capital of Lorus will be reorganized into voting common shares and non-voting common shares and the Investor will acquire from Newco and the Selling Shareholders (as defined below) approximately 41% of the voting common shares and all of the non-voting common shares by making a cash payment to Newco and the Selling Shareholders equal to approximately $8.5 million on closing of the transaction less an escrowed amount of $600,000, subject to certain post-closing adjustments.

In addition to the exchange of securities described above, shareholders who are not residents of the United States will receive voting common shares of Lorus and shareholders who are residents of the United States will receive a nominal cash payment instead of voting common shares. As well, as a condition of the agreement, High Tech Beteilingungen GmbH & Co. KG and certain other shareholders of Lorus (the “Selling Shareholders”), representing approximately 24% of Lorus’ issued and outstanding share capital, have agreed to vote in favour of the transaction and to sell to the Investor the voting common shares to be received under the agreement at the same price per share as will be paid to shareholders who are residents of the United States. The directors and officers of Lorus who are security holders have expressed their intention to vote in favour of the transaction.

Current Lorus shareholders, other than residents of the United States and the Selling Shareholders, will receive approximately 59% of the Lorus voting common shares representing, upon completion of the transaction, an economic equity interest of approximately 0.5% of Lorus in addition to their continued equity interest in Newco.

The restructuring will be completed by way of a plan of arrangement and is subject to approval by the Ontario Superior Court of Justice and Lorus’ s securityholders in accordance with applicable laws. The transaction is also subject to regulatory approval, including approval of the TSX and AMEX.

Also as a condition of the transaction, the holder of the secured convertible debentures has agreed to vote in favour of the transaction. The Company has agreed to repurchase such holder’s outstanding three million common share purchase warrants at a purchase price of $252,000.

TORONTO, CANADA - May 1, 2007 - Lorus Therapeutics Inc. (“Lorus” or the “Company”) (TSX: LOR; AMEX: LRP), a biopharmaceutical company specializing in the research and development of pharmaceutical products and technologies for the management of cancer, today announced that it has signed an agreement with 6707157 Canada Inc. (“Investor”) and an affiliate thereof to recapitalize and reorganize Lorus’ business which, if completed, will result in the addition of approximately $7.8 million in non-dilutive financing for the Company. If the transaction is completed, the funds will be used to further advance the Company’s product pipeline without diluting the equity interest of its shareholders.

“We are delighted to have entered into these arrangements,” commented Dr. Aiping Young, President and CEO of Lorus. “If approved by the securityholders we believe this arrangement will provide Lorus with a significant increase in liquidity without diluting existing securityholders. The additional funds will lessen our dependence on the capital markets and will allow us to accelerate the clinical development of our lead compounds and enhance the development of our drug pipelines. This transaction will not affect Lorus’ current shareholder equity interests, or our corporate focus except in a positive way through the additional financing.”
