Remarks:

(+) Prior to May 17, 2007, the Reporting Persons may have been deemed to be a member of a group with certain other participants in an Ad Hoc Committee of Equity Holders (the "Ad Hoc Committee") of SeraCare Life Sciences, Inc. within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended, as described in a statement on Schedule 13D jointly filed on November 16, 2006 by the Reporting Persons and other participants in the Ad Hoc Committee (as the same may be amended from time to time, the "AD Hoc Committee Schedule 13D"). For the reasons described in the Ad Hoc Committee Schedule 13D, the Reporting Persons reserved all rights to disclaim membership in a group, for purposes of Section 13(d) under the Securities Exchange Act of 1934, with the other participants in the Ad Hoc Committee. The Reporting Persons have filed a statement on Schedule 13D/A on May 18, 2007, disclaiming group membership and any continuing obligation to file jointly with the other members of the Ad Hoc Committee, in light of the dissolution of the Ad Hoc Committee on May 17, 2007.
