Form for Officers 

DEED OF INDEMNIFICATION 

THIS DEED OF INDEMNIFICATION (this “Agreement”), dated as of , 2022, is made by and between Mallinckrodt plc, a public
limited company incorporated in Ireland, and _____ (“Indemnitee”). 
 WHEREAS, prior to the date hereof, Mallinckrodt plc
and Indemnitee entered into an indemnification agreement (the “Prior Agreement”), which the parties intend to be superseded and replaced by this Agreement; 

WHEREAS, it is essential to Mallinckrodt plc to retain and attract as personnel the most capable persons available; 

WHEREAS, Indemnitee is an employee of the Mallinckrodt plc group of companies that may perform functions for or on behalf of Mallinckrodt plc
or its subsidiaries from time to time (but is not a director or secretary of Mallinckrodt plc); 
 WHEREAS, each of Mallinckrodt plc and
Indemnitee recognize the increased risk of expensive and time-consuming litigation and other claims currently being asserted against directors and officers of companies; 

WHEREAS, it is reasonable, prudent and necessary for Mallinckrodt plc contractually to obligate itself to indemnify, and to advance expenses
on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve Mallinckrodt plc or, at Mallinckrodt plc’s request while an officer of Mallinckrodt plc, another Enterprise free from
undue concern that they will not be so indemnified; 
 WHEREAS, Indemnitee is willing to serve, continue to serve and to take on additional
service for or on behalf of Mallinckrodt plc or, at Mallinckrodt plc’s request while an officer of Mallinckrodt plc, another Enterprise on the condition that the Indemnitee be indemnified as provided herein; 

WHEREAS, in recognition of Indemnitee’s need for (i) substantial protection against personal liability, (ii) specific
contractual assurance that such protection will be available to Indemnitee (regardless of, among other things, any amendment to or revocation of Mallinckrodt plc’s Articles of Association or any change in the composition of Mallinckrodt
plc’s Board of Directors or acquisition transaction relating to Mallinckrodt plc), Mallinckrodt plc wishes to provide in this Agreement for the indemnification by Mallinckrodt plc of and the advancing by Mallinckrodt plc of expenses to
Indemnitee and, to the extent insurance is maintained, to provide for the continued coverage of Indemnitee under Mallinckrodt plc’s directors’ and officers’ liability insurance policies, in each case as set forth in this Agreement;

 NOW, THEREFORE, in consideration of the above premises and of Indemnitee serving or continuing to serve Mallinckrodt plc directly or, at
its request while an officer of Mallinckrodt plc, with another Enterprise, and intending to be legally bound hereby, the parties agree as follows:

plc as a result of such transaction); or

held by such shareholders, but not from the Voting Shares of the combined entity, any shares received by Affiliates of such other entity in exchange for shares of such other entity), 

provided, however, that any occurrence that would, in the absence of this proviso, otherwise constitute a Change in Control
pursuant to any of clause (i), (iii), (iv) or (v) of this Section 1(c), shall not constitute a Change in Control if such occurrence is approved in advance by a majority of the directors on the Board.

 2. Agreement to Indemnify. 

(a) General Agreement. In the event Indemnitee was, is, or becomes a party to or witness or other participant in, or is threatened to
be made a party to or witness or other participant in, a Proceeding in whole or in part by reason of (or arising in whole or in part out of) an Indemnifiable Event, Mallinckrodt plc shall indemnify Indemnitee from and against any and all Expenses to
the fullest extent permitted by law, as the same exists or may hereafter be amended or interpreted (but in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits Mallinckrodt plc to provide
broader indemnification rights than were permitted prior thereto). The parties hereto intend that this Agreement shall provide for indemnification that is not subject to the restrictions for the indemnification of directors or secretaries under
Irish law. 
 (b) Initiation of Proceeding. Notwithstanding anything in this Agreement to the contrary, Indemnitee shall not be
entitled to indemnification pursuant to this Agreement in connection with any Proceeding initiated by Indemnitee against Mallinckrodt plc or any of its subsidiaries or any director, officer or employee of Mallinckrodt plc or any of its subsidiaries
unless (i) Mallinckrodt plc has joined in or the Board has consented to the initiation of such Proceeding; (ii) the Proceeding is one to enforce indemnification rights under Section 4; or (iii) the Proceeding
is instituted after a Change in Control and Independent Counsel has approved its initiation. 
 (c) Expense Advances. If so requested
by Indemnitee, Mallinckrodt plc shall advance (within five business days of such request) any and all Expenses to Indemnitee (an “Expense Advance”); provided that, (i) such Expense Advance shall be made only upon
delivery to Mallinckrodt plc of an undertaking by or on behalf of the Indemnitee to repay the amount thereof if and to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified against such Expenses,
(ii) Mallinckrodt plc shall not (unless a court of competent jurisdiction shall determine otherwise) be required to make an Expense Advance if and to the extent that the Reviewing Party (as defined below) has determined that Indemnitee is not
permitted to be indemnified by Mallinckrodt plc under applicable law, and (iii) if and to the extent that the Reviewing Party determines after payment of one or more Expense Advances that Indemnitee would not be permitted to be so indemnified
by Mallinckrodt plc under applicable law, Mallinckrodt plc shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse Mallinckrodt plc) for all such amounts theretofore paid. If Indemnitee has commenced or commences any action,
suit, litigation or proceeding in a court of competent jurisdiction or commences arbitration to secure a determination that Indemnitee is entitled to indemnification or Expense Advance, as provided in Section 4, any
determination made by the Reviewing Party that Indemnitee would not be permitted to be indemnified by Mallinckrodt plc under applicable law shall not be binding, and Indemnitee shall not be required to reimburse Mallinckrodt plc for any Expense
Advance until a final determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or have lapsed). Indemnitee’s obligation to reimburse Mallinckrodt plc for Expense Advances shall be unsecured and
no interest shall be charged thereon. 
 (d) Mandatory Indemnification. Notwithstanding any other provision of this Agreement, to the
extent that Indemnitee has been successful on the merits or otherwise in defense of any Proceeding relating in whole or in part to an Indemnifiable Event or in defense of any issue or matter therein, Indemnitee shall be indemnified by Mallinckrodt
plc hereunder against all Expenses incurred in connection therewith. 

  
 - 4 - 

 (e) Partial Indemnification. If Indemnitee is entitled under any provision of this
Agreement to indemnification by Mallinckrodt plc for some or a portion of Expenses, but not, however, for the total amount thereof, Mallinckrodt plc shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled,
including, but not limited to successfully resolved claims in any Proceeding. 
 (f) Prohibited Indemnification. No indemnification
pursuant to this Agreement shall be paid by Mallinckrodt plc: 
 (i) on account of any Proceeding in which a final and non-appealable judgment is rendered against Indemnitee for an accounting of profits made from the purchase or sale by Indemnitee of securities of Mallinckrodt plc pursuant to the provisions of Section 16(b) of
the Exchange Act or similar provisions of any federal, state, or local laws; 
 (ii) if a court of competent jurisdiction by
a final and non-appealable judgment shall determine that such indemnification by Mallinckrodt plc is not permitted under applicable law; 

(iii) on account of any Proceeding relating to an Indemnifiable Event as to which the Indemnitee has been convicted of a crime
constituting a felony under the laws of the jurisdiction where the criminal action had been brought (or, where a jurisdiction does not classify any crime as a felony, a crime for which Indemnitee is sentenced to death or imprisonment for a term
exceeding one year); or 
 (iv) on account of any Proceeding brought by Mallinckrodt plc or any of its subsidiaries against
Indemnitee. 
 3. Reviewing Party. Prior to any Change in Control, the reviewing party (the “Reviewing Party”) shall
be any appropriate person or body consisting of a member or members of the Board or any other person or body appointed by the Board who is not a party to the particular Proceeding with respect to which Indemnitee is seeking indemnification; after a
Change in Control, the Independent Counsel referred to below shall become the Reviewing Party. With respect to all matters arising after a Change in Control concerning the rights of Indemnitee to indemnity payments and Expense Advances under this
Agreement or any other agreement to which Mallinckrodt plc or any of its Affiliates is a party, Mallinckrodt plc’s Articles of Association or applicable law, in each case as now or hereafter in effect relating to indemnification for
Indemnifiable Events, Mallinckrodt plc shall seek legal advice only from independent counsel (“Independent Counsel”) selected by Indemnitee and approved by Mallinckrodt plc (which approval shall not be unreasonably withheld), and
who has not otherwise performed services for Mallinckrodt plc or the Indemnitee (other than in connection with indemnification matters) within the five years prior to such appointment. The Independent Counsel shall not include any person who, under
the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing Mallinckrodt plc or Indemnitee in an action, suit, litigation, proceeding or arbitration to determine Indemnitee’s rights under
this Agreement. Such counsel, among other things, shall render its written opinion to Mallinckrodt plc and Indemnitee as to whether and to what extent the Indemnitee should be permitted to be 

  
 - 5 - 

 
indemnified under applicable law. In doing so, the Independent Counsel may consult with (and rely upon) counsel in any appropriate jurisdiction who would qualify as Independent Counsel
(“Local Counsel”). Mallinckrodt plc agrees to pay the reasonable fees of the Independent Counsel and the Local Counsel and to indemnify fully such counsel against any and all expenses (including attorneys’ fees), claims,
liabilities, loss, and damages arising out of or relating to this Agreement or the engagement of Independent Counsel or the Local Counsel pursuant hereto. 

4. Indemnification Process and Appeal. 

(a) Indemnification Payment. Indemnitee shall be entitled to indemnification of Expenses, and shall receive payment thereof, from
Mallinckrodt plc in accordance with this Agreement as soon as practicable after Indemnitee has made written demand on Mallinckrodt plc for indemnification, unless the Reviewing Party has given a written opinion to Mallinckrodt plc that Indemnitee is
not entitled to indemnification under applicable law. 
 (b) Adjudication or Arbitration. (i) Regardless of any action by the
Reviewing Party, if Indemnitee has not received in full the requested indemnification or Expense Advance within thirty days after making a demand or request in accordance with Section 4(a) or
Section 2(c), as applicable (a “Nonpayment”), Indemnitee shall have the right to enforce its rights thereto under this Agreement by commencing litigation (at the Indemnitee’s option) in any court
located in the State of Delaware (a “Delaware Court”) or any court located in Ireland (an “Irish Court”), in each case, having subject matter jurisdiction thereof, seeking an initial determination by the court or by
challenging any determination by the Reviewing Party or any aspect thereof. Any determination by the Reviewing Party not challenged by Indemnitee in any such litigation shall be binding on Mallinckrodt plc and Indemnitee. The remedy provided for in
this Section 4 shall be in addition to any other remedies available to Indemnitee at law or in equity. Mallinckrodt plc and Indemnitee hereby irrevocably and unconditionally (A) consent to submit to the non-exclusive jurisdiction of all Delaware Courts and Irish Courts for purposes of any action, suit, litigation, proceeding or arbitration arising out of or in connection with this Agreement, (B) waive any
objection to the laying of venue of any such action, suit, litigation, proceeding or arbitration in any Delaware Court and any Irish Court, and (C) waive, and agree not to plead or to make, any claim that any such action, suit, litigation,
proceeding or arbitration brought in any Delaware Court or any Irish Court has been brought in an improper or inconvenient forum. For the avoidance of doubt, nothing in this Agreement shall limit any right Indemnitee may have under applicable law to
bring any action, suit, litigation, proceeding or arbitration in any other court. 
 (ii) Alternatively, in the case of a
Nonpayment, Indemnitee, at his or her option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. 

(iii) In the event that a determination shall have been made pursuant to Section 4(a) or 2(c)
of this Agreement that Indemnitee is not entitled to indemnification or Expense Advance, any action, suit, litigation, proceeding or arbitration commenced pursuant to this Section 4(b) shall be conducted in all respects as
a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to 

  
 - 6 - 

 
this Section 4(b), Mallinckrodt plc shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. If
Indemnitee an action, suit, litigation, proceeding or arbitration pursuant to this Section 4(b), Indemnitee shall not be required to reimburse Mallinckrodt plc for any advances pursuant to
Section 2(c) until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 

(iv) In the event that Indemnitee, pursuant to this Section 4(b), seeks a judicial adjudication of or
an award in arbitration to enforce his or her rights under, or to recover damages for breach of, this Agreement, and it is determined in said judicial adjudication or arbitration that Indemnitee is entitled to receive all or any part of the
indemnification or advancement of Expenses sought, Indemnitee shall be entitled to recover from Mallinckrodt plc, and shall be indemnified by Mallinckrodt plc against, any and all Expenses actually and reasonably incurred by Indemnitee in connection
with such judicial adjudication or arbitration. 
 (c) Defense to Indemnification, Burden of Proof and Presumptions. (i) It
shall be a defense to any action, suit, litigation, proceeding or arbitration brought by Indemnitee against Mallinckrodt plc to enforce this Agreement that it is not permissible under applicable law for Mallinckrodt plc to indemnify Indemnitee for
the amount claimed. 
 (ii) In connection with any action, suit, litigation, proceeding or arbitration or any determination
by the Reviewing Party or otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proving such a defense or determination shall be on Mallinckrodt plc. 

(iii) Neither the failure of the Reviewing Party to have made a determination prior to the commencement of such action, suit,
litigation, proceeding or arbitration by Indemnitee that indemnification of the Indemnitee is proper under the circumstances because Indemnitee has met the standard of conduct set forth in applicable law, nor an actual determination by the Reviewing
Party that the Indemnitee had not met such applicable standard of conduct, shall, of itself, be a defense to the action, suit, litigation, proceeding or arbitration or create a presumption that the Indemnitee has not met the applicable standard of
conduct. 
 (iv) For purposes of this Agreement, to the fullest extent permitted by law, the termination of any claim,
action, suit, litigation, proceeding or arbitration, by judgment, order, settlement (whether with or without court approval), conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that
Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. 

  
 - 7 - 

 (v) For purposes of any determination of good faith, Indemnitee shall be
deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of any Enterprise, including financial statements, or on information supplied to Indemnitee by the management of such Enterprise in the course
of their duties, or on the advice of legal counsel for such Enterprise or on information or records given or reports made to such Enterprise by an independent certified public accountant or by an appraiser or other expert selected by such
Enterprise. The provisions of this Section 4(c)(v) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of conduct
set forth in applicable law. 
 (vi) The knowledge and/or actions, or failure to act, of any other director, trustee,
partner, managing member, fiduciary, officer, agent or employee of any Enterprise shall not be imputed to Indemnitee for purposes of determining any right to indemnification under this Agreement. 

(vii) Mallinckrodt plc shall be precluded from asserting in any action, suit, litigation, proceeding or arbitration commenced
pursuant to this Agreement that the procedures or presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any court or before any arbitrator that Mallinckrodt plc is bound by all the provisions of this Agreement.

 5. Indemnification for Expenses Incurred in Enforcing Rights. In addition to Indemnitee’s rights under
Section 4(b)(iv), Mallinckrodt plc shall indemnify Indemnitee against any and all Expenses that are incurred by Indemnitee in connection with any Proceeding brought by Indemnitee: 

(a) for indemnification or advance payment of Expenses under any agreement to which Mallinckrodt plc or any of its Affiliates is a party
(other than this Agreement) or under applicable law or Mallinckrodt plc’s Articles of Association, in each case now or hereafter in effect, relating to indemnification or advance payment of Expenses for Indemnifiable Events, and/or 

(b) for recovery under directors’ and officers’ liability insurance policies maintained by Mallinckrodt plc, 

but, in either case, only in the event that Indemnitee ultimately is determined to be entitled to such indemnification or expense advance or insurance
recovery, as the case may be. In addition, Mallinckrodt plc shall, if so requested by Indemnitee, advance the foregoing Expenses and any Expenses incurred in any Proceeding brought pursuant to Section 4 to Indemnitee,
subject to and in accordance with Section 2(c). 
 6. Notification and Defense of Proceeding. 

(a) Notice. Promptly after receipt by Indemnitee of notice of the commencement of any Proceeding, Indemnitee shall, if a claim in
respect thereof is to be made against Mallinckrodt plc under this Agreement, notify Mallinckrodt plc of the commencement thereof; but the omission so to notify Mallinckrodt plc will not relieve Mallinckrodt plc from any liability that it may have to
Indemnitee, unless, and to the extent that, such failure materially prejudices the interests of Mallinckrodt plc. 

  
 - 8 - 

 (b) Defense. With respect to any Proceeding as to which Indemnitee notifies
Mallinckrodt plc of the commencement thereof, Mallinckrodt plc will be entitled to participate in the Proceeding at its own expense and except as otherwise provided below, to the extent Mallinckrodt plc so wishes, it may assume the defense thereof
with counsel reasonably satisfactory to Indemnitee. After notice from Mallinckrodt plc to Indemnitee of its election to assume the defense of any Proceeding, Mallinckrodt plc shall not be liable to Indemnitee under this Agreement or otherwise for
any Expenses subsequently incurred by Indemnitee in connection with the defense of such Proceeding other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ legal counsel in such
Proceeding, but all Expenses related thereto incurred after notice from Mallinckrodt plc of its assumption of the defense shall be at Indemnitee’s expense unless: (i) the employment of legal counsel by Indemnitee has been authorized by
Mallinckrodt plc, (ii) Indemnitee has reasonably determined that there may be a conflict of interest between Indemnitee and Mallinckrodt plc in the defense of the Proceeding, (iii) after a Change in Control, the employment of counsel by
Indemnitee has been approved by the Independent Counsel, or (iv) Mallinckrodt plc shall not in fact have employed counsel to assume the defense of such Proceeding, in each of which cases all Expenses of the Proceeding shall be borne by
Mallinckrodt plc. Mallinckrodt plc shall not be entitled to assume the defense of any Proceeding (x) brought by or on behalf of Mallinckrodt plc, (y) as to which Indemnitee shall have made the determination provided for in clause
(ii) of this Section 6(b) or (z) after a Change in Control (it being specified, for the avoidance of doubt, that Mallinckrodt plc may assume defense of any such Proceeding described in this sentence
with Indemnitee’s consent, provided that any such consent shall not affect the rights of Indemnitee under the foregoing provisions of this Section 6(b)). 

(c) Settlement of Claims. Mallinckrodt plc shall not be liable to indemnify Indemnitee under this Agreement or otherwise for any
amounts paid in settlement of any Proceeding effected without Mallinckrodt plc’s written consent, such consent not to be unreasonably withheld; provided, however, that if a Change in Control has occurred, Mallinckrodt plc shall be
liable for indemnification of Indemnitee for amounts paid in settlement if the Independent Counsel has approved the settlement. Mallinckrodt plc shall not settle any Proceeding in any manner that would impose any liability, penalty or limitation on
Indemnitee without Indemnitee’s written consent. Mallinckrodt plc’s liability hereunder shall not be excused if assumption of the defense of the Proceeding by Mallinckrodt plc was barred by this Agreement. 

7. Establishment of Trust. In the event of a Change in Control, Mallinckrodt plc shall, upon written request by Indemnitee, create a
trust for the benefit of the Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses reasonably anticipated at the time of each
such request (a) to be incurred in connection with investigating, preparing for, participating in, and/or defending any Proceeding relating to an Indemnifiable Event and (b) to be indemnifiable pursuant to this Agreement. The amount or
amounts to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by the Independent Counsel. The terms of the Trust shall provide that (i) the Trust shall not be revoked or the principal thereof invaded
without the written consent of the Indemnitee, (ii) the Trustee (as defined below) shall advance, within five business days of a request by the Indemnitee, any and all Expenses to the Indemnitee on the same terms and conditions as provided in
Section 2(c) (and the Indemnitee hereby agrees to 

  
 - 9 - 

 
reimburse the Trust under the same circumstances for which the Indemnitee would be required to reimburse Mallinckrodt plc under Section 2(c)), (iii) the Trust shall
continue to be funded by Mallinckrodt plc in accordance with the funding obligation set forth above, (iv) the Trustee shall promptly pay to the Indemnitee all amounts for which the Indemnitee shall be entitled to indemnification pursuant to
this Agreement, and (v) all unexpended funds in the Trust shall revert to Mallinckrodt plc upon a final determination by the Independent Counsel or a court of competent jurisdiction, as the case may be, that the Indemnitee has been fully
indemnified under the terms of this Agreement. The trustee of the Trust (the “Trustee”) shall be chosen by the Indemnitee. Nothing in this Section 7 shall relieve Mallinckrodt plc of any of its obligations
under this Agreement. All income earned on the assets held in the Trust shall be reported as income by Mallinckrodt plc for federal, state, local, and foreign tax purposes. Mallinckrodt plc shall pay all costs of establishing and maintaining the
Trust and shall indemnify the Trustee against any and all expenses (including attorneys’ fees), claims, liabilities, loss, and damages arising out of or relating to this Agreement or the establishment and maintenance of the Trust. 

8. Non-Exclusivity. The rights of Indemnitee hereunder shall be in addition to any other rights
Indemnitee may have under Mallinckrodt plc’s Articles of Association, applicable law or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this
Agreement in respect of any action taken or omitted by such Indemnitee in his capacity as an officer or director prior to such amendment, alteration or repeal. To the extent that a change in applicable law (whether by statute or judicial decision)
permits greater indemnification than would be afforded currently under Mallinckrodt plc’s Articles of Association, applicable law or this Agreement, it is the intent of the parties that Indemnitee enjoy by this Agreement the greater benefits so
afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment of any right hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right. 

9. Liability Insurance. For so long as Indemnitee has indemnification rights hereunder, Mallinckrodt plc shall maintain or cause to be
maintained an insurance policy or policies providing general and/or directors’ and officers’ liability insurance covering Indemnitee, in accordance with the terms of such policy or policies, to the maximum extent of the coverage available
for any director, officer, secretary or employee, as applicable, of Mallinckrodt plc, provided and to the extent that such insurance is available on a commercially reasonable basis. 

10. Continuation of Contractual Indemnity or Period of Limitations. All agreements and obligations of Mallinckrodt plc contained herein
shall continue during the period Indemnitee is an officer of Mallinckrodt plc or, upon Mallinckrodt plc’s request while serving as an officer of Mallinckrodt plc, another Enterprise, and shall continue thereafter for so long as Indemnitee shall
be subject to, or involved in, any Proceeding for which indemnification is provided pursuant to this Agreement. Notwithstanding the foregoing, no Proceeding shall be brought and no cause of action shall be asserted by or on behalf of Mallinckrodt
plc or any Affiliate of Mallinckrodt plc against Indemnitee, Indemnitee’s spouse, heirs, executors, or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, or such longer period
as may be required by the laws of Ireland under the circumstances. Any claim or cause of action of Mallinckrodt plc or its Affiliate shall be extinguished and deemed released unless asserted by the timely filing and notice of a legal action within
such period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause of action, the shorter period shall govern. 

  
 - 10 - 

 11. Enforcement. Mallinckrodt plc expressly confirms and agrees that it has entered
into this Agreement and assumes the obligations imposed on it hereby in order to induce Indemnitee to serve as an officer of Mallinckrodt plc or, upon Mallinckrodt plc’s request while an officer of Mallinckrodt plc, an officer or director of
any other Enterprise, and Mallinckrodt plc acknowledges that Indemnitee is relying upon this Agreement in serving as an officer of Mallinckrodt plc or an officer or director of such other Enterprise. 

13. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever (other than pursuant to the terms hereof), Mallinckrodt plc, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties,
excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim, including, without limitation, claims for contribution that may be brought against Indemnitee by directors, officer, employees or agents of the
Company (other than Indemnitee) who may be jointly liable with Indemnitee, relating to an Indemnifiable Event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order
to reflect (i) the relative benefits received by Mallinckrodt plc, on one hand, and Indemnitee, on the other hand, as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of
Mallinckrodt plc (and its directors, officers, employees and agents), on one hand, and Indemnitee, on the other hand, in connection with such event(s) and/or transaction(s). 

14. Amendment of this Agreement. No supplement, modification, or amendment of this Agreement shall be binding unless executed in
writing by each of the parties hereto. No waiver of any of the provisions of this Agreement shall be binding unless in the form of a writing signed by the party against whom enforcement of the waiver is sought, and no such waiver shall operate as a
continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising any right or remedy hereunder shall constitute a waiver thereof. 

15. Subrogation. In the event of payment under this Agreement to Indemnitee, Mallinckrodt plc shall be subrogated to the extent of such
payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable Mallinckrodt plc
effectively to bring suit to enforce such rights. 
 16. No Duplication of Payments. Mallinckrodt plc shall not be liable under this
Agreement to make any payment in connection with any claim made by Indemnitee to the extent Indemnitee has otherwise received payment (under any insurance policy, Mallinckrodt plc’s Articles of Association or otherwise) of the amounts otherwise
indemnifiable hereunder. 

  
 - 11 - 

 17. Binding Effect. This Agreement shall be binding upon and inure to the benefit of
and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation, or otherwise to all or substantially all of the business and/or assets of Mallinckrodt plc),
assigns, spouses, heirs, and personal and legal representatives. Mallinckrodt plc shall require and cause any successor thereof (whether direct or indirect by purchase, merger, consolidation, or otherwise) to all, substantially all, or a substantial
part, of the business and/or assets of Mallinckrodt plc, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that Mallinckrodt plc
would be required to perform if no such succession had taken place. The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity pertaining to an
Indemnifiable Event even though he or she may have ceased to serve in such capacity at the time of any Proceeding or is deceased and shall inure to the benefit of the heirs, executors, administrators, legatees and assigns of such a person. 

18. Severability. If any provision (or portion thereof) of this Agreement shall be held by a court of competent jurisdiction to be
invalid, void, or otherwise unenforceable, the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore, to the fullest extent possible, the provisions of this Agreement (including, without limitation, each
portion of this Agreement containing any provision held to be invalid, void, or otherwise unenforceable that is not itself invalid, void or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held
invalid, void or unenforceable. 
 19. Governing Law. This Agreement shall be governed by and construed and enforced in accordance
with the laws of Ireland applicable to contracts made and to be performed in Ireland without giving effects to its principles of conflicts of laws that would result in the application of the laws of another jurisdiction. 

20. Notices. All notices, demands, and other communications required or permitted hereunder shall be made in writing and shall be

 Exhibit 10.16 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”), is made by and among Sucampo Pharmaceuticals, Inc., a Delaware corporation
(“Sucampo”), and                     (“Indemnitee”). 

WHEREAS, Sucampo is a wholly owned subsidiary of Mallinckrodt plc, a public limited company incorporated in Ireland; 

WHEREAS, it is essential to Sucampo and Mallinckrodt plc that Mallinckrodt plc retain and attract as directors and secretary the most capable
persons available; 
 WHEREAS, Sucampo has requested that the Indemnitee serve as a director, officer, secretary or employee of Mallinckrodt
plc, and, if requested to do so by Sucampo, as a director, officer, secretary, employee, trustee, agent, or fiduciary of another foreign or domestic corporation, partnership, limited liability company, joint venture, employee benefit plan, trust, or
other Enterprise; and 
 WHEREAS, each of Mallinckrodt plc, Sucampo and Indemnitee recognize the increased risk of expensive and
time-consuming litigation and other claims currently being asserted against directors and officers of companies; 
 WHEREAS, it is
reasonable, prudent and necessary for Sucampo contractually to obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve
Mallinckrodt plc or, at Sucampo’s request while a director or secretary of Mallinckrodt plc, another Enterprise free from undue concern that they will not be so indemnified; 

WHEREAS, due to restrictions imposed by Irish law, the Articles of Association of Mallinckrodt plc do not confer indemnification and
advancement rights on its directors and secretary as broad as the indemnification and advancement rights that are customarily provided to the directors and secretary of a company organized under the laws of a U.S. state; 

WHEREAS, Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of Mallinckrodt plc or, at
Sucampo’s request while a director or secretary of Mallinckrodt plc, another Enterprise on the condition that the Indemnitee be indemnified as provided herein; 

WHEREAS, in recognition of Indemnitee’s need for (i) substantial protection against personal liability, and (ii) specific
contractual assurance that such protection will be available to Indemnitee (regardless of, among other things, any amendment to or revocation of Mallinckrodt plc’s Articles of Association, the certificate of incorporation or bylaws of Sucampo
(collectively, the “Sucampo Organizational Documents”) or any change in the composition of Mallinckrodt plc’s Board of Directors or acquisition transaction relating to Mallinckrodt plc), Sucampo wishes to provide in this
Agreement for the indemnification by Sucampo of and the advancing by Sucampo of expenses to Indemnitee as set forth in this Agreement; 

 NOW, THEREFORE, in consideration of the above premises and of Indemnitee serving or
continuing to serve Mallinckrodt plc directly or, at Sucampo’s request while a director or secretary of Mallinckrodt plc, with another Enterprise, and intending to be legally bound hereby, the parties agree as follows: 

1. Certain Definitions. 

(a) Affiliate: any corporation or other person or entity that directly, or indirectly through one or more intermediaries, controls or
is controlled by, or is under common control with, the person specified. 
 (b) Board: the Board of Directors of Mallinckrodt plc.

 (c) Change in Control: shall be deemed to have occurred if: 

(i) any “person,” as such term is used in Sections 3(a)(9) and 13(d) of the Exchange Act, becomes a “beneficial
owner,” as such term is used in Rule 13d-3 promulgated under the Exchange Act, of 50% or more of the Voting Shares (as defined below) of Mallinckrodt plc; 

(ii) the majority of the Board consists of individuals other than Incumbent Directors, which term means the members of the
Board as of the date hereof, provided that any person becoming a director after the date hereof whose election or nomination for election was supported by at least three-quarters of the directors who immediately prior to such election or
nomination for election comprised the Incumbent Directors shall be considered to be an Incumbent Director; 
 (iii)
Mallinckrodt plc adopts any plan of liquidation providing for the distribution of all or substantially all of its assets; 

(iv) all or substantially all of the assets or business of Mallinckrodt plc is disposed of pursuant to a merger, consolidation
or other transaction (unless the shareholders of Mallinckrodt plc immediately prior to such a merger, consolidation or other transaction beneficially own, directly or indirectly, in substantially the same proportion as they owned the Voting Shares
of Mallinckrodt plc immediately prior to such transaction, all of the Voting Shares or other ownership interests of the entity or entities, if any, that acquire all or substantially all of the assets of, or succeed to the business of, Mallinckrodt
plc as a result of such transaction); or 
 (v) Mallinckrodt plc combines with another entity and is the surviving entity
but, immediately after the combination, the shareholders of Mallinckrodt plc immediately prior to the combination hold, directly or indirectly, 50% or less of the Voting Shares of the combined entity (there being excluded from the number of shares
held by such shareholders, but not from the Voting Shares of the combined entity, any shares received by Affiliates of such other entity in exchange for shares of such other entity), 

provided, however, that any occurrence that would, in the absence of this proviso, otherwise constitute a Change in Control
pursuant to any of clause (i), (iii), (iv) or (v) of this Section 1(c), shall not constitute a Change in Control if such occurrence is approved in advance by a majority of the directors on the Board. 

  
 - 2 - 

 (d) Enterprise: Mallinckrodt plc and any other corporation, limited liability
company, partnership, joint venture, trust, employee benefit plan or other entity or enterprise of which Indemnitee is or was serving at the request of Sucampo as a director, officer, secretary, trustee, general partner, managing member, fiduciary,
board of directors’ committee member, employee or agent. 
 (e) Exchange Act: the U.S. Securities Exchange Act of 1934, as
amended. 
 (f) Expenses: any expense, liability, or loss, including attorneys’ fees, judgments, fines, ERISA excise taxes and
penalties, amounts paid or to be paid in settlement, any interest, assessments, or other charges imposed thereon, any federal, state, local, or foreign taxes imposed as a result of the actual or deemed receipt of any payments under this Agreement,
and all other costs and obligations, paid or incurred in connection with investigating, defending, prosecuting (subject to Section 2(b)), being a witness in, participating in (including on appeal), or preparing for any of
the foregoing in, any Proceeding relating to any Indemnifiable Event. Expenses also shall include Expenses incurred in connection with any appeal resulting from any Proceeding, including without limitation the premium, security for, and other costs
relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent. 
 (g) Indemnifiable Event: any event or
occurrence that took or takes place either prior to or after the execution of this Agreement, related to the fact that Indemnitee is or was a director, officer, secretary or employee of Mallinckrodt plc, or while a director or secretary of
Mallinckrodt plc is or was serving at the request of Sucampo as a director, officer, secretary, employee, trustee, agent, or fiduciary of another foreign or domestic corporation, partnership, limited liability company, joint venture, employee
benefit plan, trust, or other Enterprise, or related to anything done or not done by Indemnitee in any such capacity, whether or not the basis of the Proceeding is alleged action in an official capacity as a director, officer, secretary, employee,
trustee, agent, or fiduciary or in any other capacity while serving as a director, officer, secretary, employee, trustee, agent, or fiduciary. 

(h) Independent Counsel: the meaning specified in Section 3. 

(i) Proceeding: any threatened, pending, or completed action, suit, litigation, proceeding or arbitration or any alternative dispute
resolution mechanism (including an action by or in the right of Mallinckrodt plc), or any inquiry, hearing, tribunal or investigation, whether conducted by Mallinckrodt plc or any other party, that Indemnitee in good faith believes might lead to the
institution of any such action, suit, litigation, proceeding or arbitration, whether civil, criminal, administrative, investigative, or other, or otherwise might give rise to adverse consequences or findings in respect of the Indemnitee. 

(j) Reviewing Party: the meaning specified in Section 3. 

(k) Voting Shares: shares of any class or classes having general voting power under ordinary circumstances, in the absence of
contingencies, to elect the directors (or similar function) of an Enterprise. 

  
 - 3 - 

	 	2.	 Agreement to Indemnify. 

(a) General Agreement. In the event Indemnitee was, is, or becomes a party to or witness or other participant in, or is threatened to
be made a party to or witness or other participant in, a Proceeding in whole or in part by reason of (or arising in whole or in part out of) an Indemnifiable Event, Sucampo shall indemnify Indemnitee from and against any and all Expenses to the
fullest extent permitted by law, as the same exists or may hereafter be amended or interpreted (but in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits Sucampo to provide broader
indemnification rights than were permitted prior thereto). The parties hereto intend that this Agreement shall provide for indemnification in excess of that expressly permitted by Mallinckrodt plc’s Articles of Association, the separate deed of
indemnification which Indemnitee has with Mallinckrodt plc, the Sucampo Organizational Documents or applicable law. 
 (b) Initiation of
Proceeding. Notwithstanding anything in this Agreement to the contrary, Indemnitee shall not be entitled to indemnification pursuant to this Agreement in connection with any Proceeding initiated by Indemnitee against Mallinckrodt plc or any of
its subsidiaries or any director, officer or employee of Mallinckrodt plc or any of its subsidiaries unless (i) Mallinckrodt plc has joined in or the Board has consented to the initiation of such Proceeding; (ii) the Proceeding is one to
enforce indemnification rights under Section 4; or (iii) the Proceeding is instituted after a Change in Control and Independent Counsel has approved its initiation. 

(c) Expense Advances. If so requested by Indemnitee, Sucampo shall advance (within five business days of such request) any and all
Expenses to Indemnitee (an “Expense Advance”); provided that, (i) such Expense Advance shall be made only upon delivery to Sucampo of an undertaking by or on behalf of the Indemnitee to repay the amount thereof if and to
the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified against such Expenses, (ii) Sucampo shall not (unless a court of competent jurisdiction shall determine otherwise) be required to make an Expense
Advance if and to the extent that the Reviewing Party (as defined below) has determined that Indemnitee is not permitted to be indemnified by Sucampo under applicable law, and (iii) if and to the extent that the Reviewing Party determines after
payment of one or more Expense Advances that Indemnitee would not be permitted to be so indemnified by Sucampo under applicable law, Sucampo shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse Sucampo) for all such
amounts theretofore paid. If Indemnitee has commenced or commences any action, suit, litigation or proceeding in a court of competent jurisdiction or commences arbitration to secure a determination that Indemnitee is entitled to indemnification or
Expense Advance, as provided in Section 4, any determination made by the Reviewing Party that Indemnitee would not be permitted to be indemnified by Sucampo under applicable law shall not be binding, and Indemnitee shall
not be required to reimburse Sucampo for any Expense Advance until a final determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or have lapsed). Indemnitee’s obligation to reimburse Sucampo
for Expense Advances shall be unsecured and no interest shall be charged thereon. 

  
 - 4 - 

 (d) Mandatory Indemnification. Notwithstanding any other provision of this Agreement,
to the extent that Indemnitee has been successful on the merits or otherwise in defense of any Proceeding relating in whole or in part to an Indemnifiable Event or in defense of any issue or matter therein, Indemnitee shall be indemnified by Sucampo
hereunder against all Expenses incurred in connection therewith. 
 (e) Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by Sucampo for some or a portion of Expenses, but not, however, for the total amount thereof, Sucampo shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled,
including, but not limited to successfully resolved claims in any Proceeding. 
 (f) Prohibited Indemnification. No indemnification
pursuant to this Agreement shall be paid by Sucampo: 
 (i) on account of any Proceeding in which a final and non-appealable judgment is rendered against Indemnitee for an accounting of profits made from the purchase or sale by Indemnitee of securities of Mallinckrodt plc pursuant to the provisions of Section 16(b) of
the Exchange Act or similar provisions of any federal, state, or local laws; 
 (ii) if a court of competent jurisdiction by
a final and non-appealable judgment shall determine that such indemnification by Sucampo is not permitted under applicable law; 

(iii) on account of any Proceeding relating to an Indemnifiable Event as to which the Indemnitee has been convicted of a crime
constituting a felony under the laws of the jurisdiction where the criminal action had been brought (or, where a jurisdiction does not classify any crime as a felony, a crime for which Indemnitee is sentenced to death or imprisonment for a term
exceeding one year); or 
 (iv) on account of any Proceeding brought by Mallinckrodt plc or any of its subsidiaries against
Indemnitee. 
 3. Reviewing Party; Exhaustion of Remedies. 

(a) Prior to any Change in Control, the reviewing party (the “Reviewing Party”) shall be any appropriate person or body
consisting of a member or members of the Board or any other person or body appointed by the Board who is not a party to the particular Proceeding with respect to which Indemnitee is seeking indemnification; after a Change in Control, the Independent
Counsel referred to below shall become the Reviewing Party. With respect to all matters arising after a Change in Control concerning the rights of Indemnitee to indemnity payments and Expense Advances under this Agreement, the separate deed of
indemnification which Indemnitee has with Mallinckrodt plc or any other agreement to which Mallinckrodt plc or any of its Affiliates is a party, Mallinckrodt plc’s Articles of Association, the Sucampo Organizational Documents or applicable law,
in each case as now or hereafter in effect relating to indemnification for Indemnifiable Events, Mallinckrodt plc and Sucampo shall seek legal advice only from independent counsel (“Independent Counsel”) selected by Indemnitee and
approved by Mallinckrodt plc (which approval shall not be unreasonably withheld), and who has not otherwise performed services for Mallinckrodt plc, Sucampo or the Indemnitee (other than in connection with indemnification matters) within the five
years prior to such appointment. The Independent 

  
 - 5 - 

 
Counsel shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing Mallinckrodt plc, Sucampo or
Indemnitee in an action, suit, litigation, proceeding or arbitration to determine Indemnitee’s rights under this Agreement. Such counsel, among other things, shall render its written opinion to Mallinckrodt plc, Sucampo and Indemnitee as to
whether and to what extent the Indemnitee should be permitted to be indemnified under applicable law. In doing so, the Independent Counsel may consult with (and rely upon) counsel in any appropriate jurisdiction who would qualify as Independent
Counsel (“Local Counsel”). Sucampo agrees to pay the reasonable fees of the Independent Counsel and the Local Counsel and to indemnify fully such counsel against any and all expenses (including attorneys’ fees), claims,
liabilities, loss, and damages arising out of or relating to this Agreement or the engagement of Independent Counsel or the Local Counsel pursuant hereto. 

(b) Prior to making written demand on Sucampo for indemnification pursuant to Section 4(a) or making a request for
Expense Advance pursuant to Section 2(c), Indemnitee shall (i) seek such indemnification or Expense Advance, as applicable, under any applicable insurance policy of Mallinckrodt plc or any of its subsidiaries and
(ii) request that Mallinckrodt plc consider in its discretion whether to make such indemnification or Expense Advance, as applicable. Upon any such request by Indemnitee of Mallinckrodt plc, Mallinckrodt plc shall consider whether to make such
indemnification or Expense Advance, as applicable, based on the facts and circumstances related to the request. Mallinckrodt plc may require, as a condition to making any indemnification or Expense Advance, as applicable, that Indemnitee enter into
an agreement providing for such indemnification or Expense Advance, as applicable, to be made subject to substantially the same terms and conditions applicable to an indemnification or Expense Advance, as applicable, by Sucampo hereunder (including,
without limitation, conditioning any Expense Advance upon delivery to Mallinckrodt plc of an undertaking of the type described in clause (i) of the proviso to Section 2(c)). In the event indemnification or Expense
Advance, as applicable, is not received pursuant to such an insurance policy, or from Mallinckrodt plc, within five business days of the later of Indemnitee’s request of the applicable insurer and Indemnitee’s request of Mallinckrodt plc
as provided in the first sentence of this Section 3(b), Indemnitee may make written demand on Sucampo for indemnification pursuant to Section 4(a) or make a request for Expense Advance pursuant to
Section 2(c), as applicable. 
 4. Indemnification Process and Appeal. 

(a) Indemnification Payment. Indemnitee shall be entitled to indemnification of Expenses, and shall receive payment thereof, from
Sucampo in accordance with this Agreement as soon as practicable after Indemnitee has made written demand on Sucampo for indemnification, unless the Reviewing Party has given a written opinion to Sucampo that Indemnitee is not entitled to
indemnification under applicable law. 
 (b) Adjudication or Arbitration. (i) Regardless of any action by the Reviewing Party,
if Indemnitee has not received in full the requested indemnification or Expense Advance within thirty days after making a demand or request in accordance with Section 4(a) or Section 2(c), as
applicable (a “Nonpayment”), Indemnitee shall have the right to enforce its rights thereto under this Agreement by commencing litigation in any federal or state court located in the State of Delaware (a “Delaware
Court”) having subject matter jurisdiction thereof seeking an 

  
 - 6 - 

 
initial determination by the court or by challenging any determination by the Reviewing Party or any aspect thereof. Any determination by the Reviewing Party not challenged by Indemnitee in any
such litigation shall be binding on Mallinckrodt plc, Sucampo and Indemnitee. The remedy provided for in this Section 4 shall be in addition to any other remedies available to Indemnitee at law or in equity. Mallinckrodt
plc, Sucampo and Indemnitee hereby irrevocably and unconditionally (A) consent to submit to the non-exclusive jurisdiction of all Delaware Courts for purposes of any action, suit, litigation, proceeding
or arbitration arising out of or in connection with this Agreement, (B) waive any objection to the laying of venue of any such action, suit, litigation, proceeding or arbitration in any Delaware Court, and (C) waive, and agree not to plead
or to make, any claim that any such action, suit, litigation, proceeding or arbitration brought in any Delaware Court has been brought in an improper or inconvenient forum. For the avoidance of doubt, nothing in this Agreement shall limit any right
Indemnitee may have under applicable law to bring any action, suit, litigation, proceeding or arbitration in any other court. 

(ii) Alternatively, in the case of a Nonpayment, Indemnitee, at his or her option, may seek an award in arbitration to be
conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. 

(iii) In the event that a determination shall have been made pursuant to Section 4(a) or 2(c)
of this Agreement that Indemnitee is not entitled to indemnification or Expense Advance, any action, suit, litigation, proceeding or arbitration commenced pursuant to this Section 4(b) shall be conducted in all respects as
a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 4(b),
Sucampo shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. If Indemnitee an action, suit, litigation, proceeding or arbitration pursuant to this
Section 4(b), Indemnitee shall not be required to reimburse Sucampo for any advances pursuant to Section 2(c) until a final determination is made with respect to Indemnitee’s entitlement to
indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (iv) In the event that Indemnitee,
pursuant to this Section 4(b), seeks a judicial adjudication of or an award in arbitration to enforce his or her rights under, or to recover damages for breach of, this Agreement, and it is determined in said judicial
adjudication or arbitration that Indemnitee is entitled to receive all or any part of the indemnification or advancement of Expenses sought, Indemnitee shall be entitled to recover from Sucampo, and shall be indemnified by Sucampo against, any and
all Expenses actually and reasonably incurred by Indemnitee in connection with such judicial adjudication or arbitration. 
 (c) Defense
to Indemnification, Burden of Proof and Presumptions. (i) It shall be a defense to any action, suit, litigation, proceeding or arbitration brought by Indemnitee against Sucampo to enforce this Agreement that it is not permissible under
applicable law for Sucampo to indemnify Indemnitee for the amount claimed. 

  
 - 7 - 

 (ii) In connection with any action, suit, litigation, proceeding or
arbitration or any determination by the Reviewing Party or otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proving such a defense or determination shall be on Sucampo. 

(iii) Neither the failure of the Reviewing Party to have made a determination prior to the commencement of such action, suit,
litigation, proceeding or arbitration by Indemnitee that indemnification of the Indemnitee is proper under the circumstances because Indemnitee has met the standard of conduct set forth in applicable law, nor an actual determination by the Reviewing
Party that the Indemnitee had not met such applicable standard of conduct, shall, of itself, be a defense to the action, suit, litigation, proceeding or arbitration or create a presumption that the Indemnitee has not met the applicable standard of
conduct. 
 (iv) For purposes of this Agreement, to the fullest extent permitted by law, the termination of any claim,
action, suit, litigation, proceeding or arbitration, by judgment, order, settlement (whether with or without court approval), conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that
Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. 

(v) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of any Enterprise, including financial statements, or on information supplied to Indemnitee by the management of such Enterprise in the course of their duties, or on the advice of
legal counsel for such Enterprise or on information or records given or reports made to such Enterprise by an independent certified public accountant or by an appraiser or other expert selected by such Enterprise. The provisions of this
Section 4(c)(v) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in applicable law. 

(vi) The knowledge and/or actions, or failure to act, of any other director, trustee, partner, managing member, fiduciary,
officer, agent or employee of any Enterprise shall not be imputed to Indemnitee for purposes of determining any right to indemnification under this Agreement. 

(vii) Sucampo shall be precluded from asserting in any action, suit, litigation, proceeding or arbitration commenced pursuant
to this Agreement that the procedures or presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any court or before any arbitrator that Sucampo is bound by all the provisions of this Agreement. 

5. Indemnification for Expenses Incurred in Enforcing Rights. In addition to Indemnitee’s rights under
Section 4(b)(iv), Sucampo shall indemnify Indemnitee against any and all Expenses that are incurred by Indemnitee in connection with any Proceeding brought by Indemnitee: 

  
 - 8 - 

 (a) for indemnification or advance payment of Expenses under any agreement to which Sucampo
or any of its Affiliates is a party (other than this Agreement) or under applicable law, Mallinckrodt plc’s Articles of Association, or the Sucampo Organizational Documents, in each case now or hereafter in effect, relating to indemnification
or advance payment of Expenses for Indemnifiable Events, and/or 
 (b) for recovery under directors’ and officers’ liability
insurance policies maintained by Mallinckrodt plc, 
 but, in either case, only in the event that Indemnitee ultimately is determined to be entitled to such
indemnification or expense advance or insurance recovery, as the case may be. In addition, Sucampo shall, if so requested by Indemnitee, advance the foregoing Expenses and any Expenses incurred in any Proceeding brought pursuant to
Section 4 to Indemnitee, subject to and in accordance with Section 2(c). 
 6.
Notification and Defense of Proceeding. 
 (a) Notice. Promptly after receipt by Indemnitee of notice of the commencement of
any Proceeding, Indemnitee shall, if a claim in respect thereof is to be made against Sucampo under this Agreement, notify Mallinckrodt plc and Sucampo of the commencement thereof; but the omission so to notify Mallinckrodt plc and Sucampo will not
relieve Sucampo from any liability that it may have to Indemnitee, unless, and to the extent that, such failure materially prejudices the interests of Mallinckrodt plc or Sucampo. 

(b) Defense. With respect to any Proceeding as to which Indemnitee notifies Mallinckrodt plc and Sucampo of the commencement thereof,
Sucampo will be entitled to participate in the Proceeding at its own expense and except as otherwise provided below, to the extent Sucampo so wishes, it may assume the defense thereof with counsel reasonably satisfactory to Indemnitee. After notice
from Sucampo to Indemnitee of its election to assume the defense of any Proceeding, Sucampo shall not be liable to Indemnitee under this Agreement or otherwise for any Expenses subsequently incurred by Indemnitee in connection with the defense of
such Proceeding other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ legal counsel in such Proceeding, but all Expenses related thereto incurred after notice from Sucampo of its
assumption of the defense shall be at Indemnitee’s expense unless: (i) the employment of legal counsel by Indemnitee has been authorized by Sucampo, (ii) Indemnitee has reasonably determined that there may be a conflict of interest
between Indemnitee and Sucampo in the defense of the Proceeding, (iii) after a Change in Control, the employment of counsel by Indemnitee has been approved by the Independent Counsel, or (iv) Sucampo shall not in fact have employed counsel
to assume the defense of such Proceeding, in each of which cases all Expenses of the Proceeding shall be borne by Sucampo. Sucampo shall not be entitled to assume the defense of any Proceeding (x) brought by or on behalf of Mallinckrodt plc or
Sucampo, (y) as to which Indemnitee shall have made the determination provided for in clause (ii) of this Section 6(b) or (z) after a Change in Control (it being specified, for the avoidance of
doubt, that Sucampo may assume defense of any such Proceeding described in this sentence with Indemnitee’s consent, provided that any such consent shall not affect the rights of Indemnitee under the foregoing provisions of this
Section 6(b)). 

  
 - 9 - 

 (c) Settlement of Claims. Sucampo shall not be liable to indemnify Indemnitee under
this Agreement or otherwise for any amounts paid in settlement of any Proceeding effected without Sucampo’s written consent, such consent not to be unreasonably withheld; provided, however, that if a Change in Control has occurred,
Sucampo shall be liable for indemnification of Indemnitee for amounts paid in settlement if the Independent Counsel has approved the settlement. Sucampo shall not settle any Proceeding in any manner that would impose any liability, penalty or
limitation on Indemnitee without Indemnitee’s written consent. Sucampo’s liability hereunder shall not be excused if assumption of the defense of the Proceeding by Sucampo was barred by this Agreement. 

7. Establishment of Trust. In the event of a Change in Control, Sucampo shall, upon written request by Indemnitee, create a trust for
the benefit of the Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses reasonably anticipated at the time of each such
request (a) to be incurred in connection with investigating, preparing for, participating in, and/or defending any Proceeding relating to an Indemnifiable Event and (b) to be indemnifiable pursuant to this Agreement. The amount or amounts
to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by the Independent Counsel. The terms of the Trust shall provide that (i) the Trust shall not be revoked or the principal thereof invaded without the
written consent of the Indemnitee, (ii) the Trustee (as defined below) shall advance, within five business days of a request by the Indemnitee, any and all Expenses to the Indemnitee on the same terms and conditions as provided in
Section 2(c) (and the Indemnitee hereby agrees to reimburse the Trust under the same circumstances for which the Indemnitee would be required to reimburse Sucampo under Section 2(c)),
(iii) the Trust shall continue to be funded by Sucampo in accordance with the funding obligation set forth above, (iv) the Trustee shall promptly pay to the Indemnitee all amounts for which the Indemnitee shall be entitled to
indemnification pursuant to this Agreement, and (v) all unexpended funds in the Trust shall revert to Sucampo upon a final determination by the Independent Counsel or a court of competent jurisdiction, as the case may be, that the Indemnitee
has been fully indemnified under the terms of this Agreement. The trustee of the Trust (the “Trustee”) shall be chosen by the Indemnitee. Nothing in this Section 7 shall relieve Sucampo of any of its
obligations under this Agreement. All income earned on the assets held in the Trust shall be reported as income by Sucampo for federal, state, local, and foreign tax purposes. Sucampo shall pay all costs of establishing and maintaining the Trust and
shall indemnify the Trustee against any and all expenses (including attorneys’ fees), claims, liabilities, loss, and damages arising out of or relating to this Agreement or the establishment and maintenance of the Trust. 

8. Non-Exclusivity. The rights of Indemnitee hereunder shall be in addition to any other rights
Indemnitee may have under Mallinckrodt plc’s Articles of Association, the separate deed of indemnification which Indemnitee has with Mallinckrodt plc, the Sucampo Organizational Documents, applicable law or otherwise. No amendment, alteration
or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his capacity as an office or director prior to such
amendment, alteration or repeal. To the extent that a change in applicable law (whether by statute or judicial decision) permits greater indemnification than would be afforded currently under Mallinckrodt plc’s Articles of Association, the
separate deed of indemnification which Indemnitee has with Mallinckrodt plc, the Sucampo Organizational Documents, applicable 

  
 - 10 - 

 
law or this Agreement, it is the intent of the parties that Indemnitee enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to
be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right. 
 9.
Continuation of Contractual Indemnity or Period of Limitations. All agreements and obligations of Sucampo contained herein shall continue during the period Indemnitee is an officer or director of Mallinckrodt plc or, upon Sucampo’s
request while serving as a director or secretary of Mallinckrodt plc, another Enterprise, and shall continue thereafter for so long as Indemnitee shall be subject to, or involved in, any Proceeding for which indemnification is provided pursuant to
this Agreement. Notwithstanding the foregoing, no Proceeding shall be brought and no cause of action shall be asserted by or on behalf of Sucampo or any Affiliate of Sucampo against Indemnitee, Indemnitee’s spouse, heirs, executors, or personal
or legal representatives after the expiration of two years from the date of accrual of such cause of action, or such longer period as may be required by the laws of Delaware under the circumstances. Any claim or cause of action of Sucampo or its
Affiliate shall be extinguished and deemed released unless asserted by the timely filing and notice of a legal action within such period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause
of action, the shorter period shall govern. 
 10. Contribution. To the fullest extent permissible under applicable law, if the
indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever (other than pursuant to the terms hereof), Sucampo, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee,
whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim, including, without limitation, claims for contribution that may be brought against Indemnitee by
directors, officer, employees or agents of the Company (other than Indemnitee) who may be jointly liable with Indemnitee, relating to an Indemnifiable Event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of
the circumstances of such Proceeding in order to reflect (i) the relative benefits received by Mallinckrodt plc and Sucampo, on one hand, and Indemnitee, on the other hand, as a result of the event(s) and/or transaction(s) giving cause to such
Proceeding; and/or (ii) the relative fault of Mallinckrodt plc and Sucampo (and their respective directors, officers, employees and agents), on one hand, and Indemnitee, on the other hand, in connection with such event(s) and/or transaction(s).

 11. Enforcement. Sucampo expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed
on it hereby in order to induce Indemnitee to serve as an officer or director of Mallinckrodt plc or, upon Sucampo’s request while a director or secretary of Mallinckrodt plc, any other Enterprise, and Sucampo acknowledges that Indemnitee is
relying upon this Agreement in serving as an officer or director of Mallinckrodt plc or such other Enterprise. 
 12. Amendment of this
Agreement. No supplement, modification, or amendment of this Agreement shall be binding unless executed in writing by each of the parties hereto. No waiver of any of the provisions of this Agreement shall be binding unless in the form of a
writing signed by the party against whom enforcement of the waiver is sought, and no such waiver shall operate as a continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising any right or remedy
hereunder shall constitute a waiver thereof. 

  
 - 11 - 

 13. Subrogation. In the event of payment under this Agreement to Indemnitee, Sucampo
shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents
necessary to enable Sucampo effectively to bring suit to enforce such rights. 
 14. No Duplication of Payments. Sucampo shall not be
liable under this Agreement to make any payment in connection with any claim made by Indemnitee to the extent Indemnitee has otherwise received payment (under any insurance policy, Mallinckrodt plc’s Articles of Association, the separate deed
of indemnification which Indemnitee has with Mallinckrodt plc, the Sucampo Organizational Documents or otherwise) of the amounts otherwise indemnifiable hereunder. 

15. Binding Effect. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their
respective successors (including any direct or indirect successor by purchase, merger, consolidation, or otherwise to all or substantially all of the business and/or assets of Sucampo), assigns, spouses, heirs, and personal and legal
representatives. Sucampo shall require and cause any successor thereof (whether direct or indirect by purchase, merger, consolidation, or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of Sucampo, by
written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that Sucampo would be required to perform if no such succession had taken place.
The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity pertaining to an Indemnifiable Event even though he or she may have ceased to serve in such
capacity at the time of any Proceeding or is deceased and shall inure to the benefit of the heirs, executors, administrators, legatees and assigns of such a person. 

16. Severability. If any provision (or portion thereof) of this Agreement shall be held by a court of competent jurisdiction to be
invalid, void, or otherwise unenforceable, the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore, to the fullest extent possible, the provisions of this Agreement (including, without limitation, each
portion of this Agreement containing any provision held to be invalid, void, or otherwise unenforceable that is not itself invalid, void or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held
invalid, void or unenforceable. 
 17. Governing Law. This Agreement shall be governed by and construed and enforced in accordance
with the laws of Delaware applicable to contracts made and to be performed in such State without giving effects to its principles of conflicts of laws that would result in the application of the laws of another jurisdiction.
