Second Amendment to Merger Agreement  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On November&nbsp;1, 2018, OvaScience,&nbsp;Inc. (the "Company"), Orion Merger Sub,&nbsp;Inc. ("Merger Sub") and Millendo
Therapeutics,&nbsp;Inc. ("Millendo") entered into a Second Amendment to the Agreement and Plan of Merger and Reorganization dated as of August&nbsp;8, 2018, as amended on September&nbsp;25, 2018
(as amended from time to time, the "Merger Agreement") relating to the planned merger of Millendo with and into the Merger Sub (the "Amendment"). The Amendment, among other things, provides that the
pre-closing financing to be undertaken by Millendo, including the conversion of any convertible promissory notes issued after the date of the Merger Agreement, would be consummated at a price per
share of not less than $1.2096. The Amendment also provides that Millendo's valuation would equal the sum of $155&nbsp;million plus any proceeds received in the pre-closing financing, and that the
Company's valuation would be lowered to $45.5&nbsp;million, subject to certain adjustments set forth in the Merger Agreement. The Amendment additionally (i)&nbsp;provides that the definition of
Millendo outstanding shares used for purposes of the exchange ratio shall include shares of Millendo's common stock available for issuance under its stock option plans, (ii)&nbsp;provides for an
adjustment to the Company's net cash in connection with certain litigation matters, and (iii)&nbsp;revises the definition of the Company's outstanding lease obligations with respect to its principal
office space. It also revises certain representations and warranties being made by Millendo. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
copy of the Amendment is attached hereto as Exhibit&nbsp;2.1, and this description is qualified in its entirety by reference to the text of the Amendment. </FONT></P>

Stock Purchase Agreement  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the closing of the Merger (as defined in the Merger Agreement), the Company intends to complete a private placement financing
(the "Post-Closing Financing") with an institutional investor (the "Post-Closing Financing Investor") involving the sale of approximately $20&nbsp;million of the Company's common stock, par value
$0.001 per share. In connection with the Post-Closing Financing, on November&nbsp;1, 2018, the Company entered into a stock purchase agreement (as amended from time to time, the "Purchase
Agreement") with the Post-Closing Investor and Millendo pursuant to which such shares of the Company's common stock will be issued following the closing of the Merger. The Purchase Agreement may be
terminated as follows: (i)&nbsp;at any time prior to the closing of the Post-Closing Financing and prior to termination of the Merger Agreement by mutual written consent of the Company, Millendo and
the Post-Closing Financing Investor, (ii)&nbsp;at any time prior to the closing of the Post-Closing Financing and following termination of the Merger Agreement by either the Company, Millendo or the
Post-Closing Financing Investor, (iii)&nbsp;by the Post-Closing Financing Investor if the closing of the Post-Closing Financing has not been consummated by February&nbsp;8, 2019, (iv)&nbsp;by
Millendo or the Company if the closing of the Post-Closing Financing has not been consummated by February&nbsp;8, 2020 or (v)&nbsp;by Millendo, the Company or the Post-Closing Financing Investor
if the Post-Closing Financing would violate any nonappealable order, degree or judgment of any governmental authority having competent jurisdiction. If the Merger does not close because either the
Company or Millendo terminates the Merger Agreement in order to accept a superior offer, the Post-Closing Financing Investor will be entitled to receive a termination fee of $1&nbsp;million from the
party that owes a termination fee pursuant to the Merger Agreement. The shares of the Company's common stock issued in the Post-Closing Financing will be sold pursuant to an exemption from the
registration requirements of the Securities Act of 1933, as amended, and the resale of the Company's common stock will be registered pursuant to a resale registration statement on Form&nbsp;S-3 (the
"Resale Shelf") to be filed with the SEC. The Post-Closing Financing will not occur until the completion of the Merger and the effectiveness of such Form&nbsp;S-3, unless such conditions are waived
by the Post-Closing Financing Investor. In the event that the Merger has closed, but the Form&nbsp;S-3 has not gone effective, the Post-Closing Financing Investor will have the right, subject to the
terms of the Purchase Agreement, to </FONT></P>

Registration Rights Agreement  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the Post-Closing Financing, on November&nbsp;1, 2018, the Company entered into a Registration Rights Agreement with the
Post-Closing Financing Investor providing for the registration and resale by the Post-Closing Financing Investor of the Company's common stock issued in the Post-Closing Financing (the "Registrable
Securities"). Pursuant to the Registration Rights Agreement, the Company is required to as promptly as reasonably practical following the execution of the Registration Rights Agreement file the Resale
Shelf with respect to the Registrable Securities held by or issuable to the Post-Closing Financing Investor. Thereafter, the Company is required to file an acceleration request and use its reasonable
efforts to cause the Resale Shelf to become effective. The Company will be required to use reasonable best efforts to maintain the effectiveness of the Resale Shelf until the Registrable Securities
have been disposed of or are no longer Registrable Securities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These
registration rights granted under the Registration Rights Agreement are subject to certain conditions and limitations, including the Company's right to withdraw the Resale Shelf
under certain circumstances. The registration rights granted in the Registration Rights Agreement are subject to customary indemnification and contribution provisions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;29, 2018, the Company received notice from The Nasdaq Stock Market&nbsp;LLC ("Nasdaq") that the Company has been granted an additional 180 calendar
days, or until April&nbsp;22, 2019, to regain compliance with the minimum $1.00 bid price per share requirement of the Nasdaq listing rules. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
previously disclosed, on April&nbsp;27, 2018, the Company received a written notification from Nasdaq's Listing Qualifications Department that it had failed to comply with Nasdaq
Listing Rule&nbsp;5450(a)(1) because the bid price for the Company's common stock over a period of 30 consecutive business days prior to such date had closed below the minimum $1.00 per share
requirement for continued listing. In accordance with Nasdaq Listing Rule&nbsp;5810(c)(3)(A), the Company was afforded an initial period of 180 calendar days, or until October&nbsp;24, 2018, to
regain compliance with Rule&nbsp;5450(a)(1). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company determined that it would not be in compliance with Rule&nbsp;5450(a)(1) by October&nbsp;24, 2018, and on October&nbsp;22, 2018, submitted an application to transfer the
Company's common stock from listing on the Nasdaq Global Market to the Nasdaq Capital Market. Doing so allowed the Company to become eligible for an additional 180&nbsp;day compliance period
provided for companies listed on the Nasdaq Capital Market, provided that the Company met the continued listing requirements for market value of publicly held shares and all other initial listing
standards for the Nasdaq Capital Market, with the exception of the minimum bid price requirement, and provided written notice of its intention to cure the deficiency during the second compliance
period by effecting a reverse stock split, if necessary. </FONT></P>

<A NAME="page_ca72809_1_4"> </A>

<P style="font-family:times;"><FONT SIZE=2>In
accordance with the original notification, the Company indicated in its transfer application that it met all of the other continuing listing requirements for the Nasdaq Capital Market, with the
exception of the bid price requirement, and provided written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accordingly,
at the opening of business on October&nbsp;31, 2018, the listing of the shares of the Company's common stock was transferred from the Nasdaq Global Market to the Nasdaq
Capital Market. The Company's common stock will continue to trade under the symbol "OVAS." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
at any time before April&nbsp;22, 2019 the bid price of the Company's common stock closes at or above $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will
provide written notice that the Company has achieved compliance with the Nasdaq listing rules. If the Company does not regain compliance by April&nbsp;22, 2019, the Company expects that Nasdaq will
provide written notice that the Company's common stock will be delisted. At that time, the Company may appeal Nasdaq's determination to a Nasdaq hearing panel. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company believes that the completion of its proposed merger with Millendo will address the Nasdaq compliance matter described in this Current Report on Form&nbsp;8-K. The Company
will continue to monitor the bid price for its common stock and consider various other options available to it if its common stock does not trade at a level that is likely to regain compliance. </FONT></P>

1934, as amended, and Section&nbsp;27A of the Securities Act of 1933, as amended) concerning OvaScience, Millendo, the proposed transaction and other matters. These statements may discuss goals,
intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of the management of OvaScience, as well as
assumptions made by, and information currently available to, management. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events
or conditions, and include words such as "may," "will," "should," "would," "expect," "anticipate," "plan," "likely," "believe," "estimate," "project," "intend," and other similar expressions.
Statements that are not historical facts are forward-looking statements. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not
guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: the risk
that the conditions to the closing of the transaction are not satisfied, including the failure to obtain stockholder approval for the transaction in a timely manner or at all; uncertainties as to the
timing of the consummation of the transaction and the ability of each of OvaScience and Millendo to consummate the transaction; risks related to OvaScience's continued listing on the Nasdaq Stock
Market until closing of the proposed transaction; risks related to OvaScience's ability to correctly estimate its operating expenses and its expenses associated with the transaction; the ability of
OvaScience or Millendo to protect their respective intellectual property rights; competitive responses to the transaction; unexpected costs, charges or expenses resulting from the transaction;
potential adverse reactions or changes to business relationships resulting from the announcement or completion of the transaction; and legislative, regulatory, political and economic developments. The
foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are
included herein and elsewhere, including the risk factors included in OvaScience's most recent Annual Report on Form&nbsp;10-K, Quarterly Reports on Form&nbsp;10-Q, the Registration Statement on

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Great Point Partners has joined the previously-disclosed investor syndicate, which includes New Enterprise Associates, Frazier Healthcare Partners, and Roche Venture Fund, among others, bringing the total expected proceeds of the financing to approximately $50 million in the combined company, at the same valuation as the merger. Together with the approximately $37 million in net cash expected from OvaScience at closing, the total proceeds of the merger and financing are expected to be approximately $87 million. The </font>proceeds will fund the further development of Millendo&#146;s lead assets, livoletide and nevanimibe. The financing and merger are expected to close in the fourth quarter of 2018.</p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;</font>We are pleased to welcome this syndicate of high-quality investors, while ensuring that we have the resources in place to advance our first-in-class programs for the treatment of orphan endocrine diseases,&#148; said Julia Owens, Ph.D., President and Chief Executive Officer of Millendo. &#147;We look forward to providing an update on our clinical progress, beginning with the initiation of our pivotal Phase 2b/3 study of livoletide in Prader-Willi syndrome, in the first quarter of 2019.&#148;</p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;We believe that with these updated terms and additional funding from recognized investors, the merger of OvaScience and Millendo has the potential to deliver even more significant and immediate value to shareholders and ultimately, to patients,&#148; said Christopher Kroeger, M.D., Chief Executive Officer of OvaScience.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In conjunction with the additional investment by Great Point Partners, the estimated exchange ratio in the merger agreement has been revised, giving OvaScience securityholders greater ownership of the combined company &#151; now with a post-money valuation of approximately $246 million - than pursuant to the former exchange ratio. On a pro forma basis, current OvaScience securityholders will own approximately 17% of the combined company, current Millendo securityholders (assuming the Millendo option pool is fully allocated) will own approximately 63% of the combined company (exclusive of participation in the associated financing), and investors participating in the financing will acquire approximately 20% of the combined company, in each case excluding the available OvaScience option</font></p>

In March&nbsp;2018, the Company announced preliminary blinded data for its Phase 1 trial of OvaPrime for women with primary ovarian insufficiency and poor ovarian response. This trial was not expected to result in strong signals on secondary endpoints. The Company has since completed additional preclinical studies and based on results from these studies, has scaled back investment in its research and development efforts to focus on evaluating strategic alternatives.
