Together with the Aquiline Shares owned by Pan American prior to the making of the Share Offer, Pan American, following the take up of Aquiline Shares deposited to the Share Offer to date, owns 74,270,417 Aquiline Shares, representing approximately 92.4% of the Aquiline Shares issued and outstanding as at December 22, 2009.

In addition, Pan American has been advised by Kingsdale that an additional 206,366 of Aquiline's February 2008 series of common share purchase warrants and Aquiline's outstanding convertible debenture have been deposited to Pan American's offers to acquire each outstanding series of Aquiline's common share purchase warrants (the "Aquiline Warrants") and the Aquiline convertible debenture (together with the Share Offer, the "Offers"). As a consequence, Pan American now owns 100% of the outstanding Aquiline Warrants issued in October 2008 and 86.9% of the outstanding Aquiline Warrants issued in February 2008.

All of the conditions to the Offers have been satisfied and, accordingly, Pan American has taken up all Aquiline Securities deposited to the Offers. The Offers expired in accordance with their terms at 9:00 pm (Eastern time) on December 22, 2009.

Pan American expects to complete the compulsory acquisition within the next 90 days.
