February 3, 2011 at 12:34 PM EST

No. BILLERICA, Mass. (February 3, 2011) – Lantheus Medical Imaging, Inc. (the “Company”) announced today that it has completed its previously announced offer to exchange (the “Exchange Offer”) up to $250,000,000 in aggregate principal amount of its currently outstanding 9.750% Senior Notes due 2017 (the “Initial Notes”) for an equal aggregate principal amount of its new 9.750% Senior Notes due 2017 (the “New Notes”) that have been registered under the Securities Act of 1933, as amended (the “Securities Act”). 
                                                                                            
The Exchange Offer was made pursuant to a Registration Rights Agreement entered into by the Company when it originally issued the Initial Notes on May 10, 2010. As the Company issued the Initial Notes in a private placement transaction, the Initial Notes were subject to transfer restrictions. The purpose of the Exchange Offer was to allow holders of the Initial Notes to exchange their notes for New Notes that did not have these restrictions. Following the Exchange Offer, the Company will continue to have $250,000,000 aggregate principal amount of notes outstanding.

The terms of the New Notes issued in the Exchange Offer are substantially the same as the terms of the Initial Notes, except that the New Notes are registered under the Securities Act, have no transfer restrictions under the federal securities laws, no registration rights and no rights to additional interest. All of the Initial Notes were submitted for exchange, and the Company has accepted for exchange all the Initial Notes validly tendered and not withdrawn pursuant to the Exchange Offer.

This announcement does not constitute an offer to purchase or a solicitation of an offer to sell securities. The Exchange Offer was made only pursuant to a prospectus and the related letter of transmittal and only to such persons and in such jurisdictions as is permitted under applicable law.
