Lantheus commences solicitation with respect to 9.750% Senior Notes Due 2017

Lantheus Medical Imaging, Inc. ("Lantheus") today announced it commenced a consent solicitation (the "Solicitation") with respect to a proposed amendment to the indenture (the "Indenture") governing the company's outstanding 9.750% Senior Notes Due 2017 (the "Notes") (CUSIP No. 516545 AC4). The proposed amendment would modify the restricted payments covenant to provide for a $150 million restricted payments basket. The proposed amendments would enable Lantheus to undertake an offering of additional notes under the Indenture and use the proceeds to make a distribution to Lantheus' immediate parent company and indirectly to Lantheus' ultimate parent company, Lantheus MI Holdings, Inc. ("Holdings") to allow Holdings to, among other things, repurchase Holdings' outstanding preferred stock.

The record date to determine holders of the Notes entitled to consent is March 2, 2011. The Solicitation will expire at 5:00 p.m., New York City time, on March 14, 2011 (the "Expiration Date"), unless extended. As part of the Solicitation, Lantheus will make a cash payment (the "Consent Payment") of $15 per $1,000 in principal amount of Notes to each Holder who has validly delivered a duly executed consent (the "Consent") on or prior to the Expiration Date and who has not revoked that Consent in accordance with the procedures described in the Consent Solicitation Statement (the "Solicitation Statement"). Lantheus' obligation to make the Consent Payment is contingent, among other things, upon receipt of the Requisite Consents (as defined in the Solicitation Statement), which Consents have not been properly revoked on or prior to the Expiration Date and satisfaction or waiver, where possible, of the conditions described in the Solicitation Statement, including the consummation of an offering of additional notes under the Indenture in an aggregate principal amount of $150 million. Lantheus currently expects to commence such Notes offering following the Expiration Date. The Consent Payment will be paid promptly following the satisfaction of the conditions outlined in the Solicitation Statement, including the consummation of the additional notes offering.
