On December 19, 2018, the Delaware Chancery Court issued an opinion in Sciabacucchi v. Salzberg, C.A. No. 2017-0931-JTL, invalidating provisions in the certificates of incorporation of Delaware companies that purport to limit to federal court the forum in which a stockholder could bring a claim under the Securities Act of 1933, as amended. The Chancery Court held that a Delaware corporation can only use its governing documents to bind a plaintiff to a particular forum where the claim involves rights or relationships established by or under Delaware’s corporate law. This case may be appealed to the Delaware Supreme Court.

Article VII of our Amended and Restated Certificate of Incorporation (the “Charter”) contains a similar federal forum selection provision. As such, and in light of the recent Sciabacucchi decision, we do not currently intend to enforce the foregoing federal forum selection provision unless the Sciabacucchi decision is appealed and the Delaware Supreme Court reverses the decision. If there is no appeal of the Sciabacucchi decision or if the Delaware Supreme Court affirms the Chancery Court’s decision, we will seek approval by our stockholders, at our next regularly scheduled annual meeting of stockholders, to amend the Charter to remove such provision.
