Dear Jeff,

On behalf of Aimmune Therapeutics (the "Company", or "Aimmune"), it is a great
pleasure to extend you this offer of employment as Chief Operating Officer in
Brisbane, CA. Your start date with Aimmune Therapeutics will be no later than
February 1, 2016 and you agree to give formal notice to Adamas Pharmaceuticals
no later than December 28, 2015.

You will be reporting to me as the CEO of Aimmune Therapeutics.

Base Salary

In this position, you will earn an annual base salary of $375,000 which will be
paid on a semi-monthly basis.

Future Salary Increases

At Aimmune, employees who join between January 1 and December 31 of a given
calendar year are eligible to be considered for a salary merit increase during
the next calendar year's Annual Compensation Review process. The Annual
Compensation Review process generally takes place in the first quarter of the
calendar year. Salary merit increases, if any, will be awarded at the Company's
discretion on the basis of your performance.

Sign-On Bonus

To compensate for your loss of corporate bonus payout at Adamas Pharmaceuticals,
we will pay you a sign-on bonus of $150,000 payable as follow:·

 

•

$75,000 will be paid in cash on the first regularly scheduled Company payroll
date following your start date.

 

 

•

The other half will be provided in the form of 5,000 RSUs to be fully cliff
vested one year from your start date. Your RSUs will be approved in the first
Board of Directors meeting following your start date.

 

You certify, by your signature on the offer letter below, that you will not
accept any corporate bonus payment from Adamas for 2015 performance, which is
the basis for this sign-on bonus.

In addition to your sign-on bonus, you will receive a $15,000 annual lump sum
bonus in each of the next two years, paid out on March 1, 2017 and March 1,
2018. However, if your target bonus changes from 35% of salary to 40% of salary
during this timeframe, you will receive the adjusted target bonus % in lieu of
any remaining payments of the annual $15,000 lump sum bonus referenced above.

If you voluntarily resign from the Company on or prior to the one-year
anniversary of your Hire Date, you acknowledge and agree that you will be
obligated to repay to the Company 100% of your cash Sign-on Bonuses by no later
than sixty (60) days from the date of your resignation.

Annual  Bonus Program

You will also be eligible to participate in Aimmune's annual bonus program.
Current target bonus opportunity for your position is 35% of your annual base
salary, with the actual amount of such bonus, if any, being determined by the
Company in its sole discretion, based on your performance and that of the
Company against goals established by the Board. You must commence your
employment by September 30 in order to be eligible for a bonus for the calendar
year during which you were hired. If you join the Company between January 1 and
September 30, you will be eligible for a pro­ rated bonus for that calendar
year. You must be employed through the date bonuses are disbursed to employees
generally in order to be eligible for the bonus. Aimmune reserves the right to
change or eliminate its annual bonus program.

New Hire Option Grant

The Company will recommend to the Board of Directors that it grant you an option
to purchase 250,000 shares of the Company's common stock (the "Stock Option") at
a per share exercise price equal to the fair market value of a share of the
Company's common stock on the date of grant (as determined by the Board).
Subject to your continued employment with the Company through the applicable
vesting date, 25% of the shares underlying the Stock Option will vest on the
first anniversary of the date you commence employment with the Company and
1/48th of the total number of shares initially underlying the Stock Option will
vest on each monthly anniversary thereafter. The Stock Option will otherwise be
subject to the terms and conditions of Aimmune's stock option plan and a stock
option agreement to be entered into between you and Aimmune.

Annual Equity Grant Program

You may also be eligible to be considered for the Company's annual equity grant
program based on your performance. If you join the Company between January 1 and
September 30 of the current calendar year, you will be eligible for a prorated
annual equity grant in the calendar year that follows, with the actual amount of
such equity grant, if any, being determined by the Company in its sole
discretion and approved by our Board of Directors. If you join the Company after
September 30 of the current calendar year, your eligibility to participate will
be postponed to the following calendar year.

In addition to your salary, you will be eligible for all of Aimmune's standard
