Form of Incentive Stock Option Agreement under 2010 Stock Incentive Plan



 Exhibit 10.2 

INFINITY PHARMACEUTICALS, INC. 

Incentive Stock Option 

Granted Under 2010 Stock Incentive Plan (the “Plan”) 

1. Grant of Option. It is intended that the option shall 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 herein, shall be deemed to include any person who acquires the right to
exercise the option validly under its terms. 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 (the “Shares”) of common stock, $0.001 par value per share (“Common Stock”), of Infinity Pharmaceuticals, Inc. (the “Company”) for which it is vested until the earlier of the expiration of the
option or the termination of the option under Section 2 hereof or the Plan. 
 2. Exercise of Option. 

(a) Form of Exercise. Each election to exercise the option shall be in writing (which may be in electronic form), signed by the
Participant, and accompanied by 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 the option may be for any fractional share.

 (b) Continuous Relationship with the Company Required. Except as otherwise provided in this Section 2, the option
may not be exercised unless the Participant, at the time he or she exercises the option, is, and has been at all times since the date of grant, an employee or officer of, or consultant or advisor to, the Company or any parent or subsidiary of the
Company as defined in Section 424(e) or (f) of the Code (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 the option shall terminate three months after
such cessation (but in no event after the option expiration date), provided that the option shall be exercisable only to the extent that the Participant was entitled to exercise the option on the date of such cessation. Notwithstanding
the foregoing, if the Participant, prior to the option expiration 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 the 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 option expiration 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, the 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 the option shall be exercisable only to the extent that the option was exercisable by the Participant on the date of his or her death or disability, and further provided that the option shall
not be exercisable after the option expiration date. 
 (e) Termination for Cause. If, prior to the option expiration
date, the Participant’s employment is terminated by the Company for Cause (as defined below), the right to exercise the option shall terminate immediately upon the effective date of such termination of employment. If the Participant is party to
an employment or severance agreement with the Company that contains a definition of “cause” for termination of employment, “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 shall be considered to have been discharged for
Cause if the Company determines, within 30 days after the Participant’s resignation, that discharge for cause was warranted. 
 3. Tax
Matters. No Shares will be issued pursuant to the exercise of the 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 the option. If the Participant disposes of Shares acquired upon exercise of the option within two years from the grant date or one year after such Shares were acquired pursuant to exercise of the option, the
Participant shall notify the Company in writing of such disposition. 
 4. Nontransferability of Option. The 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, the option shall be
exercisable only by the Participant; provided, however, that the Participant may make a gratuitous transfer of this option to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the
Participant and/or an immediate family member thereof so long as the Company is eligible to use a Form S-8 under the Securities Act for the registration of the sale of the Common Stock subject to this option to such proposed transferee; provided
further, that the Company shall not be required to recognize any such permitted transfer until such time as such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument in form and substance
satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of this option. 
 5.
