Pursuant to the terms of the Agreement, on August 28, 2018 (the “Grant Date”), the Company granted Mr. Gagnon an inducement award of an option to purchase 450,000 shares of its common stock at an exercise price equal to $9.43, the closing price of the Company’s common stock as reported by the Nasdaq Global Market on the Grant Date. 350,000 shares of the stock option will vest at the rate of twenty-five percent (25%) on the one-year anniversary of the Grant Date and as to an additional 6.25% of the shares at the end of each successive three-month period following the first anniversary of the Grant Date. The remaining 100,000 shares will vest upon achievement of $150 million in “net sales” of duvelisib within the first 24 months of the first commercial sale of duvelisib. These awards are subject to Mr. Gagnon’s continuing service with the Company at the time of vesting.

The Company also granted Mr. Gagnon 50,000 restricted stock units, all of which will vest on the first anniversary of the Grant Date, subject to Mr. Gagnon’s continuing service with the Company at the time of vesting.

Under the Agreement and subject to the execution and effectiveness of a release of claims at such time, Mr. Gagnon would be entitled to severance payments if the Company terminates his employment without Cause, as defined in the Agreement, or if Mr. Gagnon terminates his employment with the Company for Good Reason, as defined in the Agreement.

(e)          This Agreement shall automatically terminate in the event of the Executive’s death during employment.  The Company may terminate the Executive’s employment, upon notice to the Executive, in the event the Executive becomes disabled during employment and, as a result, is unable to continue to perform substantially all of his material duties and responsibilities under this Agreement for one-hundred and twenty (120) days during any period of three hundred and sixty-five (365) consecutive calendar days.  If any question shall arise as to whether the Executive is disabled to the extent that the Executive is unable to perform substantially all of his material duties and responsibilities for the Company and its Affiliates, the

ii.               The Company shall pay, on the Payment Commencement Date, a lump sum payment equal to twelve (12) months of the Executive’s then-current annual base salary; provided, however, that if such termination occurs prior to a Change of Control, such severance payments shall be made at the time and in the manner set forth in Section 5(a)(i) during the period beginning on the date of termination through the date of the Change of Control with any severance remaining to be paid under this Section 5(c)(ii) payable in a lump sum on the closing date of the Change of Control (or, if later, the Payment Commencement Date).

iii.            If the Executive is participating in the Company’s group health plan and/or dental plan at the time the Executive’s employment terminates, and the Executive exercises his right to continue participation in those plans under the federal law known as COBRA, or any successor law, the Company will pay the Executive the Benefits Payment for twelve (12) months following the date on which the Executive’s employment with the Company terminates or, if earlier, until the date the Executive becomes eligible to enroll in the health (or, if

6

applicable, dental) plan of a new employer, with such amount payable on a pro-rata basis in accordance with the Company’s regular payroll practices for benefits beginning on the Payment Commencement Date.

v.              Any obligation of the Company to provide the Executive severance payments or other benefits under this Section 5(c) (other than the Accrued Amounts) is conditioned on the Executive’s signing, returning and not revoking the Employee Release by the deadline specified therein (and in all events within 60 days following the termination of the Executive’s employment), which release shall not apply to (i) claims for indemnification in the Executive’s capacity as an officer or director of the Company under the Company’s Certificate of Incorporation, By-laws or agreement, if any, providing for director or officer indemnification, (ii) rights to receive insurance coverage and payments under any policy maintained by the Company and (iii) rights to receive retirement benefits that are accrued and fully vested at the time of the Executive’s termination and rights under such plans protected by ERISA.

1.                                      Subject to this Exhibit A, any severance payments that may be due under the Agreement shall begin only upon the date of the Executive’s “separation from service” (determined as set forth below) which occurs on or after the termination of Executive’s employment.  The following rules shall apply with respect to distribution of the severance payments, if any, to be provided to Executive under the Agreement, as applicable:

(a)                                  It is intended that each installment of the severance payments under the Agreement provided under shall be treated as a separate “payment” for purposes of Section 409A.  Neither the Company nor Executive shall have the right to accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A.

(b)                                  If, as of the date of Executive’s “separation from service” from the Company, Executive is not a “specified employee” (within the meaning of Section 409A), then each installment of the severance payments shall be made on the dates and terms set forth in the Agreement.

(c)                                   If, as of the date of Executive’s “separation from service” from the Company, Executive is a “specified employee” (within the meaning of Section 409A), then:

(i)                                        Each installment of the severance payments due under the Agreement that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when Executive’s separation from service occurs, be paid within the short-term deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid on the dates and terms set forth in the Agreement; and

(ii)                                     Each installment of the severance payments due under the Agreement that is not described in this Exhibit A, Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following Executive’s “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, Executive’s death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following Executive’s separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments if and to the maximum extent that that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service).  Any installments that qualify for the exception under

11

Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of Executive’s second taxable year following the taxable year in which the separation from service occurs.

2.                                      The determination of whether and when Executive’s separation from service from the Company has occurred shall be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h).  Solely for purposes of this Exhibit A, Section 2, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and 414(c) of the Code.

3.                                      The Company makes no representation or warranty and shall have no liability to Executive or to any other person if any of the provisions of the Agreement (including this Exhibit) are determined to constitute deferred compensation subject to Section 409A but that do not satisfy an exemption from, or the conditions of, that section.
