<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On April&nbsp;30, 2013, OvaScience,&nbsp;Inc. (the &#147;Company&#148;) filed a restated certificate of incorporation (the &#147;Restated Certificate&#148;) with the Secretary of State of the State of Delaware in connection with listing of the Company&#146;s common stock on the NASDAQ Global Market (&#147;NASDAQ&#148;). The Company&#146;s board of directors and stockholders previously approved the Restated Certificate to become effective upon the listing of the Company&#146;s common stock on NASDAQ, which occurred on April&nbsp;30, 2013. The Restated Certificate amends and restates the Company&#146;s certificate of incorporation in its entirety to, among other things, prohibit stockholders from taking any action by written consent in lieu of a meeting.&#160; The foregoing description of the Restated Certificate is qualified by reference to the Restated Certificate, a copy of which is attached hereto as Exhibit&nbsp;3.1 and is incorporated herein by reference.</font></p>

Pursuant to the terms of the Company&#146;s amended and restated voting agreement dated March 29, 2012, by and among the Company and certain holders of the Company&#146;s common stock, the voting agreement terminated on April 30, 2013, the first day on which the Company&#146;s common stock traded on a national securities exchange. Upon the termination of the voting agreement, the obligations to vote pursuant to the terms of the voting agreement ceased to apply with respect to any stockholder meeting held after the date of such termination.</font></p>

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
On April 30, 2013, OvaScience, Inc. (the "Company") filed a restated certificate of incorporation (the "Restated Certificate") with the Secretary of State of the State of Delaware in connection with listing of the Company's common stock on the NASDAQ Global Market ("NASDAQ"). The Company's board of directors and stockholders previously approved the Restated Certificate to become effective upon the listing of the Company's common stock on NASDAQ, which occurred on April 30, 2013. The Restated Certificate amends and restates the Company's certificate of incorporation in its entirety to, among other things, prohibit stockholders from taking any action by written consent in lieu of a meeting.  The foregoing description of the Restated Certificate is qualified by reference to the Restated Certificate, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.
Also on April 30, 2013, the second amended and restated by-laws of the Company (the "Amended and Restated By-Laws"), previously approved by the Company's board of directors to become effective immediately upon the listing of the Company's common stock on NASDAQ, became effective.  The Amended and Restated By-Laws amend and restate the Company's by-laws in their entirety to, among other things prohibit stockholders from taking any action by written consent in lieu of a meeting.  The foregoing description of the Amended and Restated By-Laws is qualified by reference to the Amended and Restated By-Laws, a copy of which is attached hereto as Exhibit 3.2 and is incorporated herein by reference.
8.01 Other Events.
On April 30, 2013 the Company's common stock began trading on NASDAQ, a national securities exchange. Pursuant to the terms of the Company's amended and restated voting agreement dated March 29, 2012, by and among the Company and certain holders of the Company's common stock, the voting agreement terminated on April 30, 2013, the first day on which the Company's common stock traded on a national securities exchange. Upon the termination of the voting agreement, the obligations to vote pursuant to the terms of the voting agreement ceased to apply with respect to any stockholder meeting held after the date of such termination.
