Re:		Contract Sales and Services Agreement dated May 16, 2006, by and between Cardinal Health PTS, LLC (“Cardinal Health”) and Cumberland Pharmaceuticals, Inc. (“Cumberland”), as amended by First Amendment to Contract Sales and Services Agreement dated July 19, 2006 (collectively referred to as the “Agreement”)

Dear Mr. Kazimi:

     As you may already know, Cardinal Health has signed a definitive agreement to sell its Healthcare Marketing Services division to Platinum Equity. This transaction includes Cardinal Health’s Contract Sales Organization (“CSO Business”) that is providing detailing and sampling services under the Agreement. Cardinal Health and Platinum Equity expect the transaction to close before the end of 2006.

     In connection with the sale of the CSO Business, Cardinal Health will need to assign the Agreement to Platinum Equity. As Section 18.7 of the Agreement requires Cumberland to consent to an assignment of the Agreement, we are requesting that Cumberland provide its consent by signing the Consent to Assignment attached.

     We look forward to continuing to provide you the same high level of service you expect and deserve. Please feel free to contact me at Tel: (614)  ###-###-#### with any questions you may have about this transition. We would like to receive your consent as soon as possible, but no later than November 22, 2006.

     Thank you for your assistance in this matter.

Very Truly Yours,

/s/ Thomas Dimke
