(e) Approval of the AAC Holdings, Inc. Employee Stock Purchase Plan

On December 22, 2014, the Board of Directors (the “Board”) of AAC Holdings, Inc., a Nevada corporation (the “Company”) approved the AAC Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”), subject to the approval of the Company’s stockholders within twelve months of the date the ESPP was adopted. The ESPP will become effective on January 1, 2015. A summary of the principal provisions of the ESPP is set forth below. This summary is qualified in its entirety by reference to the full text of the ESPP, which is attached as Exhibit 4.4 to the Company’s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on December 23, 2014 (File No. 333-201218), and incorporated herein by reference.

The ESPP is intended to qualify for certain tax benefits accorded to broad-based employee stock purchase plans under Section 423 of the Internal Revenue Code. Employees of the Company and its participating subsidiaries (as designated by the Company) who own less than five (5) percent of the total combined voting power or value of all classes of stock of the Company or any parent or subsidiary, and whose customary employment is more than twenty (20) hours per week and more than five (5) months in a calendar year are eligible to participate in the ESPP. The aggregate number of shares of common stock that may be issued under the ESPP is 250,000, subject to proportionate adjustment in the event of a stock split, stock dividend, reclassification, recapitalization, merger, reorganization, or other change in the Company’s structure affecting the common stock. The ESPP is implemented pursuant to option periods lasting for six (6) months, commencing on January 1 and July 1 of each year and ending on June 30 and December 31 of each year. Unless otherwise established by the plan administrator, the exercise price of the options granted under the ESPP for any option period shall be the lesser of eighty-five percent (85%) of the closing market price of the stock on the exercise date or eighty-five percent (85%) of the closing market price of the stock on the grant date. Subject to certain limitations set forth in the ESPP, the Board may at any time amend or terminate the ESPP. In addition, certain amendments to the ESPP must be approved by the Company’s stockholders.
