Solutions, Inc. Amended and Restated 2014 Employee Stock Purchase Plan (the "Plan").

Estimated in accordance with Rules 457(c) and (h) under the Securities Act solely for the purpose of calculating the registration fee. The computation is based upon 85% (see explanation in following sentence) of
the average of the high and low prices of the Common Stock as reported on the Nasdaq Global Select Market on August 18, 2014. Pursuant to the Plan, the purchase price of a share of Common Stock is an amount equal to 85% of the Fair Market Value
of a share of Common Stock on the first day of the Offering Period or the Purchase Date (as such terms are defined in the Plan), whichever is lower.
EXPLANATORY NOTE
This Registration Statement on Form S-8 relates to the registration of an additional 100,000 shares of common stock, par value $0.01 per share
("Common Stock") of Medidata Solutions, Inc., or the Registrant, for future issuance under the Medidata Solutions, Inc. Amended and Restated 2014 Employee Stock Purchase Plan (the "Plan"). In accordance with General
Instruction E to Form S-8, the contents of the previous Registration Statement on Form S-8 related to the Plan (Commission File No. 333-192861, filed on December 13, 2013 with the Securities and Exchange Commission) are incorporated herein
by reference and made part of this Registration Statement, except as amended hereby. At the Annual Meeting held on May 28, 2014, the Registrant's stockholders voted to approve the Plan, which amends and restates the Registrant's 2013
