RE: 2020/2021 Retention Bonus

Dear _____:

To incentivize you to remain with and committed to Mallinckrodt plc (the
“Company” or “we”) and its subsidiaries (collectively “Mallinckrodt”) we are
offering you a 2020/2021 Retention Bonus of $[ l ] (the “2020/2021 Retention
Bonus”) upon the terms set forth in this letter agreement (the “Agreement”). In
order to be eligible for the 2020/2021 Retention Bonus you must sign and return
this letter agreement to me by September 1, 2020 acknowledging your agreement to
the terms specified in this letter agreement. Please refer to Appendix A for
certain definitions applicable to terms used in this Agreement.

If you accept this offer, then on September 3, 2020 we will advance and pre-pay
to you the full amount of the 2020/2021 Retention Bonus (less required and
elected withholdings), subject to your agreement to repay the Net After-Tax
Value (as defined below) of the 2020/2021 Retention Bonus to the Company if it
is not earned on the terms and conditions set forth below.

You will earn the 2020/2021 Retention Bonus and will not have to repay it if (i)
you are employed by a Mallinckrodt entity on May 15, 2022 or, if applicable, an
Emergence Event, if earlier (such date, the “Vesting Date”). You will also earn
the 2020/2021 Retention Bonus in full if your employment is terminated in a
Qualifying Termination prior to the Vesting Date and you (or your estate in case
of death) sign and do not revoke the Company’s standard general release of
claims within 45 days of your termination. If you retire or resign or you are
terminated for Cause prior to the Vesting Date, then you will not earn the
2020/2021 Retention Bonus and you will be required to repay the Net After-Tax
Value of the 2020/2021 Retention Bonus to the Company, as provided below. If
your employment is terminated in a Qualifying Termination prior to the Vesting
Date and you (or your estate) fail to return the required release within 45 days
of your termination or revoke the release, then you also will not have earned
the 2020/2021 Retention Bonus and will be required to repay it.

If you are required to repay the 2020/2021 Retention Bonus under this Agreement,
then the amount of repayment will equal the Retention Bonus less the product of
the Retention Bonus and the highest effective marginal combined federal, state
and local income tax rate for the year in which the repayment event occurs
applicable to individual taxpayers residing in the your city and state (the “Net
After-Tax Value”). You agree to repay the Net After-Tax Value promptly, but in
no event more than thirty (30) days following your termination. Mallinckrodt may
offset and reduce any other compensation owed you, such as unpaid wages,
unreimbursed business expenses and deferred compensation payments, by the amount
of the Net After-Tax Value you are required to repay. However, no compensation
will be reduced if doing so would violate applicable law, or would result in
penalty taxes under Section 409A of the Internal Revenue Code. We reserve all
other rights and remedies available to recoup the Net After-Tax Value of the
2020/2021 Retention Bonus advanced under this Agreement, including the right to
file a legal claim in court.

Except as may otherwise be required by law, you agree not to disclose-the
existence of this Agreement or any of its terms to anyone other than your spouse
or domestic partner and any financial or legal advisor who agrees to be bound
not to make any such disclosure.

This Agreement does not confer upon you any right to continue in the employment
of Mallinckrodt for any period or interfere with or otherwise restrict in any
way the rights of your employer or you to terminate your employment at any time
for any reason whatsoever, with or without Cause.

This Agreement will in all respects be governed by and construed in accordance
with, the laws of the State of New Jersey, without reference to conflicts of law
principles thereunder. Any litigation arising out of this Agreement shall be
brought exclusively in the federal or state courts of New Jersey, to which
jurisdiction you and the Company hereby submit with respect to litigation
arising out of this Agreement, and both you and the Company hereby knowingly and
willingly waive their rights to a jury trial in any such litigation.

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

Note that the 2020/2021 Retention Bonus is in addition to the Retention Bonus
awarded to you pursuant to that certain Retention Bonus Letter by and between
you and the Company, dated as of [ l ], 2019, (the “2019 Retention Bonus
Letter”). For the avoidance of doubt, nothing in this Agreement supersedes the
2019 Retention Bonus Letter, which remains in full force and effect.

Please indicate your acceptance of the provisions of this letter agreement by
signing the enclosed copy of this letter agreement and returning it to my
attention by September 1, 2020.

Very truly yours,

Agreed and Accepted.
