 officers, or employees. Our amended and restated certificate of incorporation that will become effective immediately prior to the closing of this offering will provide that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:

| • |     | any derivative action or proceeding brought on our behalf; |

| • |     | any action asserting a breach of fiduciary duty; |

| • |     | any action asserting a claim against us arising under the DGCL, our amended and restated certificate of 
 incorporation, or our amended and restated bylaws;                                                      |

| • |     | any action seeking to interpret, apply, enforce or determine the validity of our amended and restated certificate 
 of incorporation, or our amended and restated bylaws;                                                             |

| • |     | any action to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; and |

| • |     | any action asserting a claim against us that is governed by the internal-affairs doctrine. |

This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all 77

such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. Additionally, investors cannot waive compliance with the federal securities
laws and the rules and regulations thereunder. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated certificate of
incorporation will further provide that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined
that such choice of forum provisions are facially valid and several state trial courts have enforced such provisions and required that suits asserting Securities Act claims be filed in federal court, there is no guarantee that courts of appeal will
affirm the enforceability of such provisions and a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and
enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and the provisions may not be
enforced by a
