Exhibit 10.8
Millendo Therapeutics, Inc.
Inducement Grant Outside of
2012 Stock Incentive Plan

Option Agreement
(Nonstatutory Stock Option)

1. Grant of Option.

This agreement (“Agreement”) evidences the grant by Millendo Therapeutics, Inc.,
a Delaware corporation (formerly known as OvaScience, Inc.) (the “Company”), on
[●] (the “Grant Date”) to [●], an employee, consultant and/or director of the
Company (the “Participant”), of an option to purchase, in whole or in part, a
total of [●] shares (the “Shares”) of common stock, $0.001 par value per share,
of the Company (“Common Stock”) at $[●] per Share. Unless earlier terminated,
this option shall expire at 5:00 p.m., Eastern time, on [●] (the “Final Exercise
Date”).

It is intended that the option evidenced by this Agreement shall not be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended, and any regulations promulgated thereunder (the “Code”).
Except as otherwise indicated by the context, the term “Participant”, as used in
this option, shall be deemed to include any person who acquires the right to
exercise this option validly under its terms.

The option is granted in compliance with NASDAQ Listing Rule 5634(c)(4) as a
material inducement to the Participant entering into employment with the
Company. The option is granted outside of, but subject to the terms of, the
Company’s 2012 Stock Incentive Plan (the “Plan”) and other relevant Plan
provisions as if the option had been granted as a Nonstatutory Stock Option
under Section 5 of the Plan, provided that for the avoidance of doubt, the
shares of Common Stock subject to this option shall not reduce and shall have no
impact on the number of shares available for grant under the Plan. If there is
any conflict between the terms in this Agreement and the Plan, the terms of the
Plan will control.

2. Vesting Schedule.

This option will become exercisable (“vest”) as to 25% of the original number of
Shares on the first anniversary of the Vesting Commencement Date and as to the
remaining Shares in equal monthly installments over 36 months following the
first anniversary of the Vesting Commencement Date. For purposes of this
Agreement, “Vesting Commencement Date” shall mean [●].
The right of exercise shall be cumulative so that to the extent the option is
not exercised in any period to the maximum extent permissible it shall continue
to be exercisable, in whole or in part, with respect to all Shares for which it
is vested until the earlier of the Final Exercise Date or the termination of
this option under Section 3 hereof or the Plan.

3. Exercise of Option.

(a) Form of Exercise. Each election to exercise this option shall be accompanied
by a completed Notice of Stock Option Exercise in the form attached hereto as
Exhibit A, signed by the Participant, and received by the Company at its
principal office, accompanied by this Agreement, and payment in full in the
manner provided in the Plan. The Participant may purchase less than the number
of Shares covered hereby, provided that no partial exercise of this option may
be for any fractional share.

(b) Continuous Relationship with the Company Required. Except as otherwise
provided in this Section 3, this option may not be exercised unless the
Participant, at the time he or she exercises this option, is, and has been at
all times since the Grant Date, an employee, officer or director of, or
consultant or advisor to, the Company or any other entity the employees,
officers, directors, consultants, or advisors of which are eligible to receive
option grants under the Plan (an “Eligible Participant”).

(c) Termination of Relationship with the Company. If the Participant ceases to
be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), provided that this option shall be exercisable only to the extent that
the Participant was entitled to exercise this option on the date of such
cessation. Notwithstanding the foregoing, if the Participant, prior to the Final
Exercise Date, violates the non-competition or confidentiality provisions of any
employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon such violation.

--------------------------------------------------------------------------------

(d) Exercise Period Upon Death or Disability. If the Participant dies or becomes
disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final
Exercise Date while he or she is an Eligible Participant and the Company has not
terminated such relationship for “cause” as specified in paragraph (e) below,
this option shall be exercisable, within the period of one year following the
date of death or disability of the Participant, by the Participant (or in the
case of death by an authorized transferee), provided that this option shall be
exercisable only to the extent that this option was exercisable by the
Participant on the date of his or her death or disability, and further provided
that this option shall not be exercisable after the Final Exercise Date.

(e) Termination for Cause. If, prior to the Final Exercise Date, the
Participant’s employment or other relationship with the Company is terminated by
the Company for Cause (as defined below), the right to exercise this option
shall terminate immediately upon the effective date of such termination of
employment or other relationship. If, prior to the Final Exercise Date, the
Participant is given notice by the Company of the termination of his or her
employment or other relationship by the Company for Cause, and the effective
date of such employment or other termination is subsequent to the date of the
delivery of such notice, the right to exercise this option shall be suspended
from the time of the delivery of such notice until the earlier of (i) such time
as it is determined or otherwise agreed that the Participant’s employment or
other relationship shall not be terminated for Cause as provided in such notice
or (ii) the effective date of such termination of employment or other
relationship (in which case the right to exercise this option shall, pursuant to
the preceding sentence, terminate immediately upon the effective date of such
termination of employment or other relationship). If the Participant is party to
an employment, consulting or severance agreement with the Company that contains
a definition of “cause” for termination of employment or other relationship,
“Cause” shall have the meaning ascribed to such term in such agreement.
Otherwise, “Cause” shall mean willful misconduct by the Participant or willful
failure by the Participant to perform his or her responsibilities to the Company
(including, without limitation, breach by the Participant of any provision of
any employment, consulting, advisory, nondisclosure, non-competition or other
similar agreement between the Participant and the Company), as determined by the
Company, which determination shall be conclusive. The Participant’s employment
or other relationship shall be considered to have been terminated for “Cause” if
the Company determines, within 30 days after the Participant’s resignation, that
termination for Cause was warranted.

4. Withholding.

No Shares will be issued pursuant to the exercise of this option unless and
until the Participant pays to the Company, or makes provision satisfactory to
the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this option.

5. Transfer Restrictions.

This option may not be sold, assigned, transferred, pledged or otherwise
encumbered by the Participant, either voluntarily or by operation of law, except
by will or the laws of descent and distribution, and, during the lifetime of the
Participant, this option shall be exercisable only by the Participant.

6. Provisions of the Plan.

This option is subject to the provisions of the Plan (including the provisions
relating to amendments to the Plan), a copy of which is furnished to the
Participant with this option.

IN WITNESS WHEREOF, the Company has caused this option to be executed under its
corporate seal by its duly authorized officer. This option shall take effect as
a sealed instrument.

(7) [I represent, warrant and covenant as follows:

I am purchasing the Shares for my own account for investment only, and not with
a view to, or for sale in connection with, any distribution of the Shares in
violation of the Securities Act of 1933 (the “Securities Act”), or any rule or
regulation under the Securities Act.

I have had such opportunity as I have deemed adequate to obtain from
representatives of the Company such information as is necessary to permit me to
evaluate the merits and risks of my investment in the Company.

I have sufficient experience in business, financial and investment matters to be
able to evaluate the risks involved in the purchase of the Shares and to make an
informed investment decision with respect to such purchase.

I can afford a complete loss of the value of the Shares and am able to bear the
economic risk of holding such Shares for an indefinite period.

I understand that (i) the Shares have not been registered under the Securities
Act and are “restricted securities” within the meaning of Rule 144 under the
Securities Act, (ii) the Shares cannot be sold, transferred or otherwise
disposed of unless they

--------------------------------------------------------------------------------

are subsequently registered under the Securities Act or an exemption from
registration is then available; (iii) in any event, the exemption from
registration under Rule 144 will not be available for at least one year and even
then will not be available unless a public market then exists for the Common
Stock, adequate information concerning the Company is then available to the
public, and other terms and conditions of Rule 144 are complied with; and (iv)
there is now no registration statement on file with the Securities and Exchange
Commission with respect to any stock of the Company and the Company has no
obligation or current intention to register the Shares under the Securities
Act.]

Very truly yours,(Signature)
