Exhibit 4.11 UNIT PURCHASE OPTIONCLARIFICATION AGREEMENT This Unit Purchase Option Clarification Agreement (this Agreement), dated March 28, 2007, is to amend the Unit
Purchase Option, dated as of August 25, 2003 (the Option), issued by NationsHealth, Inc., a Delaware corporation (the
Company), to EarlybirdCapital, Inc. (Option Holder). WHEREAS, the parties hereto desire to amend the Option to clarify that the Option Holder does not have the right,
and did not have the right at the time of issuance of the Option, to receive a net cash settlement in the event the
Company does not maintain a current prospectus relating to the units, common stock and warrants issuable upon exercise
of the Option at the time such Option is exercisable. NOW, THEREFORE, in consideration of the mutual agreements contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby,
the parties hereto agree to amend the Option as set forth herein. 4. Option. The undersigned hereby agree that the Option is hereby amended by adding the following as
Section 2.1.1 to the Option: 2.1.1 No Exercise of Purchase Option if a Registration Statement is not Effective. Notwithstanding
anything herein to the contrary, the Company shall not be obligated to deliver any securities pursuant to the exercise
of this Purchase Option unless (i) a registration statement under the Act with respect to the Units, Warrants and
Common Stock issuable upon such exercise is effective, or (ii) in the opinion of counsel to the Company or counsel to
the Holder reasonably satisfactory to the Company, the exercise of this Purchase Option is exempt from the registration
requirements of the Act, as defined below, and such securities are qualified for sale or exempt from qualification
under applicable securities laws of the states or other jurisdictions in which the registered holders reside. This
Purchase Option may not be exercised by, or securities issued to, any registered holder in any state in which such
exercise or issuance would be unlawful. The Holders are not, and at the time of the initial issuance of this Purchase
Option were not, entitled to receive a net-cash settlement or other consideration in lieu of physical settlement in
securities if the securities underlying this Purchase Option are not covered by an effective registration statement. 5. Damages. The undersigned hereby agree that solely for the reason outlined in the recital clause of
this Agreement and without otherwise in any way limiting any rights the Holder may have under applicable law as a
result of a breach by the Company of any provision of the Option, the Option is hereby amended by deleting Section 5.3
in its entirety.  1
