Explanatory Note

PharMerica Corporation (the Company) filed its Annual Report on Form 10-K for the year ended December 31, 2010 with the Securities and Exchange Commission (SEC) on
February 24, 2011 (the Original Filing). We are filing this Amendment No. 1 to the Annual Report on Form 10-K (the First Amendment and together with the Original Filing, the Form 10-K) to refile
Exhibit 10.40 in response to comments received from the SEC relating to a confidential treatment request that we made for certain portions of Exhibit 10.40 in the Original Filing.

Other than as described above, none of the other disclosures in the Original Filing have been amended or updated. Among other things,
forward-looking statements made in the Original Filing have not been revised to reflect events that occurred or facts that became known to the Company after the filing of the Original Filing and such forward-looking statements should be read in
their historical context. Accordingly, the First Amendment should be read in conjunction with the Original Filing and the Companys filings with the SEC subsequent to the Original Filing.
