Explanation of Responses:

1. The filing of this Form 4 shall not be construed as an admission that DSC Advisors, L.P. ("DSCA), the investment manager of Delaware Street Master Fund, L.P. (the "Fund"), DSC Managers, L.L.C. ("DSCM"), the general partner of the Fund, DSC Advisors, L.L.C. ("DSCA LLC"), the general partner of DSCA, or Andrew G. Bluhm, the principal of DSCA LLC, is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, or otherwise the beneficial owner of any of the Common Stock, par value $0.0001 (the "Common Stock"), of KemPharm, Inc. (the "Issuer") purchased by the Fund. Pursuant to Rule 16a-1, each of DSCA, DSCM, DSCA LLC and Mr. Bluhm disclaim such beneficial ownership.

2. The Fund holds the shares of Common Stock directly. DSCA serves as the investment manager to the Fund. DSCA LLC serves as the general partner of DSCA. DSCM receives a portion of the profits in the form of a capital allocation from, and owns a partnership interest in, the Fund. Andrew G. Bluhm reports the Common Stock held directly by the Fund because, as the principal of DSCA LLC at the time of purchase, he controlled the disposition and voting of the securities.
