(b) The Parties shall use their respective commercially reasonable efforts to obtain the Consents required to Transfer any Contracts, licenses, permits, authorizations and other Assets as contemplated by this Agreement. Notwithstanding anything herein to the contrary, no Contract or other Asset shall be Transferred if it would violate applicable Law or, in the case of a Contract, the rights of any Third Party to such Contract; provided, that Section 2.9, to the extent provided therein, shall apply to such Asset or Contract.

(c) It is understood and agreed by the Parties that certain of the Transfers or Assumptions referenced in Section 2.2(a) have heretofore occurred and, as a result, no additional Transfers or Assumptions by any member of the Alkermes Group or Mural Group, as applicable, shall be deemed to occur upon the execution of this Agreement with respect thereto. Moreover, to the extent that any member of the Alkermes Group or Mural Group, as applicable, is liable for any Alkermes Retained Liability or Mural Liability, respectively, by operation of Law immediately following any Transfer in accordance with this Agreement or any Conveyancing and Assumption Instruments, there shall be no need for any other member of the Alkermes Group or Mural Group, as applicable, to Assume such Liability in connection with the operation of Section 2.2(a) and, accordingly, no other member of such Group shall Assume such Liability in connection with Section 2.2(a).

(a) Unless the Parties otherwise agree or the benefits of any Contract described in this Section 2.3 are expressly conveyed to the applicable Party pursuant to an Ancillary Agreement, in the case of a Shared Contract, the Parties shall use commercially reasonable efforts to cause such Shared Contract to be: (i) assigned in relevant part to a member of the Mural Group (or to a member of the Alkermes Group if the contracting party is a member of the Mural Group) if so assignable; (ii) appropriately amended, prior to, on or after the Distribution Effective Time; or (iii) replaced or otherwise addressed with suitable arrangements, in each case so that each Party or its respective Subsidiaries shall be entitled to the rights and benefits and shall assume the related portion of any obligations and Liabilities inuring to their respective businesses; provided, however, that in no event shall either Party or its respective Subsidiaries be required to assign or amend any Shared Contract in its entirety or to assign a portion of any Shared Contract that is not assignable or cannot be amended by its terms (including any terms imposing Consents or conditions on an assignment where such Consents or conditions have not been obtained or fulfilled). If any Shared Contract cannot be so partially assigned, or cannot be amended, or if such assignment or amendment would impair the benefit the parties thereto derive from such Shared Contract and such Shared Contract is not replaced or otherwise addressed with suitable arrangements, Alkermes and Mural shall, and shall cause each member of their respective Groups to, take such other reasonable and permissible actions to cause (with the costs and expenses of any such actions following the Separation to be shared equally between the Parties): (A) the Assets associated with that portion of each Shared Contract that relates to the Oncology Business to be enjoyed by a member of the Mural Group; (B) the Liabilities associated with that portion of each Shared Contract that relates to the Oncology Business to be borne by a member of the Mural Group; (C) the Assets associated with that portion of each Shared Contract that relates to the Neuroscience Business to be enjoyed by a member of the Alkermes Group; and (D) the Liabilities associated with that portion of each Shared Contract that relates to the Neuroscience Business to be borne by a member of the Alkermes Group.

(c) Each of Alkermes and Mural shall, and shall cause the members of its Group to, (A) treat for all Tax purposes the portion of each Shared Contract inuring to its respective businesses as Assets owned by, and/or Liabilities of, as applicable, such Party as of the Distribution Effective Time and (B) neither report nor take any Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by a change in applicable Tax Law or good faith resolution of a Tax Contest).

Mural covenants not to breach any terms or conditions of any Alkermes In-Licenses pertaining to sublicensees thereunder and to perform and take such actions as may be required to allow Alkermes to comply with its obligations thereunder, including obligations relating to sublicensing, patent matters, confidentiality, reporting, audit rights and diligence. Mural further agrees to reimburse Alkermes (or to pay directly to the other party under the applicable Alkermes In-License, if Alkermes and such other party so agree) all amounts that become due and payable under the Alkermes In-Licenses on account of Mural’s exercise of the rights under the Alkermes In-Licenses that are sublicensed to Mural hereunder.

No such terminated agreement, arrangement, course of dealing or understanding (including any provision thereof that purports to survive termination) shall be of any further force or effect after the Distribution Effective Time.

22

Section 2.9 Transfers Not Effected at or Prior to the Distribution Effective Time; Transfers Deemed Effective as of the Distribution Effective Time.

(a) If and to the extent that the valid, complete and perfected Transfer to the Mural Group of any Mural Asset or Assumption by the Mural Group of any Mural Liability, in each case contemplated hereby, would be a violation of applicable Law or require any Consent in connection with the Separation that has not been obtained or made by the Distribution Effective Time then, unless the Parties mutually shall otherwise agree, the Transfer to the Mural Group of such Mural Assets or the Assumption by the Mural Group of such Mural Liabilities, as the case may be, shall be automatically deemed deferred and any such purported Transfer or Assumption shall be null and void until such time as all legal impediments are removed or such Consent has been obtained or made.

Notwithstanding the foregoing, any such Alkermes Retained Assets or Alkermes Retained Liabilities shall continue to constitute Alkermes Retained Assets and Alkermes Retained Liabilities, as applicable, for all other purposes of this Agreement.

(c) With respect to Assets and Liabilities described in Section 2.9(a) and Section 2.9(b) or described on Schedule 2.9(d), taking into account any applicable restrictions or considerations relating to the contemplated Tax treatment of the transactions contemplated hereby, each of Alkermes and Mural shall, and shall cause the members of its respective Group to, (i) treat for all Tax purposes (A) the deferred Assets as assets having been Transferred to and owned by the Person entitled to such Assets not later than the Distribution Effective Time and (B) the deferred Liabilities as having been Assumed by the Person intended to be subject to such Liabilities not later than the Distribution Effective Time and (ii) neither report nor take any Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by a change in applicable Tax Law or good faith resolution of a Tax Contest).

(ii) except as described on Schedule 2.9(d), (A) the Party (or the applicable member of its Group) retaining such Asset shall thereafter hold (or shall cause such member in its Group to hold) such Asset in trust for the use and benefit of the Party entitled thereto (at the expense of the Party entitled thereto) and shall be treated as holding it as nominee for the Party entitled thereto, and (B) the Party intended to Assume such Liability shall, or shall cause the applicable member of its Group to, pay or reimburse the Party retaining such Liability for all amounts paid or incurred in connection with the retention of such Liability. To the extent the foregoing applies to any Contracts to be assigned for which any necessary Consents are not received prior to the Distribution Effective Time, the treatment of such Contracts shall, for the avoidance of doubt, be subject to Section 2.12 and Section 2.13, to the extent applicable. In addition, the Party (or the applicable member of its Group) retaining such Asset or Liability shall (or shall cause such member in its Group to) treat, insofar as reasonably possible and to the extent permitted by applicable Law, such Asset or Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the Party to which such Asset is to be Transferred or by the Party Assuming such Liability in order to place such Party, insofar as reasonably possible and to the extent permitted by applicable Law, in the same position as if such Asset or Liability had been Transferred or Assumed as contemplated hereby, and so that all the benefits and burdens relating to such Asset or Liability, including possession, use, risk of loss, potential for income and gain, and dominion, control and command over such Asset or Liability, are to inure from and after the Distribution Effective Time to the applicable member or members of the Alkermes Group or the Mural Group entitled to the receipt of such Asset or required to Assume such Liability. In furtherance of the foregoing, the Parties agree that, as of the Distribution Effective Time, each Party shall be deemed to have acquired complete and sole beneficial ownership over all such Assets, together with all rights, powers and privileges incident thereto, and shall be deemed to have Assumed in accordance with the terms of this Agreement all such Liabilities, and all duties, obligations and responsibilities incident thereto, which such Party is entitled to acquire or required to Assume pursuant to the terms of the Transaction Agreements.

24

(e) If and when the Consents or conditions, the absence or non-satisfaction of which caused the deferral of Transfer of any Asset or deferral of the Assumption of any Liability pursuant to Section 2.9(a) or Section 2.9(b), are obtained or satisfied, or, if and when the inadvertent transfer or omission of an Asset or Liability is discovered by the Parties or any other impediment (legal or otherwise) that caused the Parties to delay the Transfer of any Asset or the Assumption of any Liability has been remedied, the Transfer or Assumption of the applicable Asset or Liability shall be promptly effected without further consideration in accordance with and subject to the terms of this Agreement (including Section 2.2) or the applicable Ancillary Agreement, and shall, to the extent possible without the imposition of any undue cost on any Party, be deemed to have become effective as of the Distribution Effective Time.

(f) The Party (or the applicable member of its Group) retaining any Asset or Liability due to the deferral of the Transfer of such Asset or the deferral of the Assumption of such Liability pursuant to Section 2.9(a) or Section 2.9(b) or otherwise shall (i) not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced, assumed, or agreed in advance to be reimbursed by the Party (or the applicable member of its Group) entitled to such Asset or the Person intended to be subject to such Liability, other than reasonable attorneys’ fees and recording or similar or other incidental fees, all of which shall be promptly reimbursed by the Party (or the applicable member of its Group) entitled to such Asset or the Person intended to be subject to such Liability and (ii) be indemnified for all Indemnifiable Losses or other Liabilities arising out of any actions (or omissions to act) of such retaining Party taken (or not taken) at the written direction of the other Party (or the applicable member of its Group) in connection with and relating to such retained Asset or Liability, as the case may be.

25

(ii) any member of the Alkermes Group, Mural shall execute a guarantee agreement in the form of the existing guarantee or such other form as is agreed to by the relevant parties to such guarantee agreement, which agreement shall include the removal of any Security Interest on or in any Alkermes Retained Asset that may serve as collateral or security for any such Alkermes Retained Liability, except to the extent that such existing guarantee contains representations, covenants or other terms or provisions either (A) with which Mural would be reasonably unable to comply or (B) which Mural would not reasonably be able to avoid breaching.

THE DISTRIBUTION

Section 4.1 Distribution.

(a) Subject to the terms and conditions of this Agreement (including the conditions set out in Section 4.5), Alkermes agrees that, on the Distribution Date and with effect from the Distribution Effective Time, it will take all necessary steps to effect the Distribution (including, without limitation, transferring its entire legal and beneficial interest in the issued capital stock of Mural US to Mural).

(b) Subject to the terms and conditions of this Agreement (including the conditions set out in Section 4.5), Mural agrees that the Mural Ordinary Shares (that are to be delivered in the Distribution) shall be credited as fully paid up and free from any liens, charges and encumbrances whatsoever and shall have the rights described in the Amended and Restated Memorandum and Articles of Association adopted pursuant to Section 4.3(f).

(c) Subject to the terms and conditions of this Agreement (including the conditions set out in Section 4.5), each Record Holder will be entitled to receive in the Distribution a number of whole Mural Ordinary Shares equal to the number of Alkermes Ordinary Shares held by such holder on the Record Date multiplied by the Distribution Ratio and rounded down to the nearest whole number, with any residual fractional interest dealt with in accordance with Section 4.2 below.

30

(d) Subject to the conditions and other terms set forth in this Article IV, on or prior to the Distribution Date, Mural shall deliver to the Distribution Agent for the benefit of the Record Holders all of the Mural Ordinary Shares to be delivered in the Distribution and shall, to the extent permitted by applicable Law, cause the transfer agent for the Alkermes Ordinary Shares to instruct the Distribution Agent to distribute on the Distribution Date the appropriate number of Mural Ordinary Shares to each Record Holder or designated transferee or transferees of such Record Holder by way of registration in book-entry form. Mural will not issue paper share certificates. No action by any shareholder (or such shareholder’s designated transferee or transferees) shall be necessary to receive the applicable number of Mural Ordinary Shares (and, if applicable, cash in lieu of any fractional shares) to which such shareholder is entitled in the Distribution. The Distribution shall be effective at the Distribution Effective Time.

Section 4.2 Fractional Shares. Record Holders who, after aggregating the number of Mural Ordinary Shares (or fractions thereof) to which such shareholder would be entitled on the Record Date, would be entitled to receive a fraction of a Mural Ordinary Share in the Distribution, will be entitled to receive cash in lieu of such fractional share. Fractional Mural Ordinary Shares will not be issued by Mural in the Distribution. The Distribution Agent shall, as soon as practicable after the Distribution Date, (a) determine the number of whole and fractional Mural Ordinary Shares allocable to each such Record Holder, (b) aggregate all such fractional shares into whole shares and sell the whole shares obtained thereby in open market transactions at then prevailing trading prices on behalf of holders who would otherwise be entitled to fractional share interests, and (c) distribute to each such holder, or for the benefit of each such beneficial owner, such holder’s or owner’s pro rata share of the aggregate net cash proceeds of these sales, after making appropriate deductions for any amount required to be withheld for U.S. federal income tax purposes. Alkermes shall bear the cost of brokerage fees and transfer Taxes incurred in connection with these sales of fractional shares, which such sales shall occur as soon after the Distribution Date as practicable and as determined by the Distribution Agent. None of Alkermes, Mural or the Distribution Agent will guarantee any minimum sale price for the fractional Mural Ordinary Shares. Neither Alkermes nor Mural will pay any interest on the proceeds from the sale of fractional shares. The Distribution Agent will have the sole and absolute discretion to select the broker-dealers through which to sell the aggregated fractional shares and to determine when, how and at what price to sell such shares. Neither the Distribution Agent nor the selected broker-dealers will be Affiliates of Alkermes or Mural.

(a) Except (x) as provided in Section 6.1(b), (y) as may be otherwise expressly provided in this Agreement or in any Ancillary Agreement and (z) for any matter for which either Party is entitled to indemnification pursuant to this Article VI or under any Ancillary Agreement:

(i) Alkermes, for itself and each member of the Alkermes Group and, to the extent permitted by Law, all Persons who at any time prior to the Distribution Effective Time were directors, officers, agents or employees of any member of the Alkermes Group (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, does hereby remise, release and forever discharge Mural and the other members of the Mural Group and all Persons who at any time prior to the Distribution Effective Time were shareholders, directors, officers, agents or employees of any member of the Mural Group (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, from any and all

35

(A) Alkermes Retained Liabilities and (B) Liabilities existing or arising: (1) in connection with the implementation of the Separation (including the Distribution); or (2) from actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to the Distribution Effective Time (whether or not such Liabilities cease being contingent, mature, become known, are asserted or foreseen, or accrue, in each case before, at or after the Distribution Effective Time), in each case to the extent relating to, arising out of or resulting from the Neuroscience Business, the Alkermes Retained Assets or the Alkermes Retained Liabilities, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, in each case, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed on or before the Distribution Effective Time, including in connection with the Separation and any of the other transactions contemplated hereunder and under the Ancillary Agreements (such liabilities, the “Alkermes Released Liabilities”) and in any event shall not, and shall cause its respective Subsidiaries not to, bring any Action against any member of the Mural Group in respect of any Alkermes Released Liabilities. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to limit Alkermes, any member of the Alkermes Group, or their respective Affiliates from commencing any Actions against any Mural officer, director, agent or employee, or their respective heirs, executors, administrators, successors and assigns, with regard to matters arising from, or relating to criminal acts by any such officers, directors, agents or employees.

(ii) Mural, for itself and each member of the Mural Group and, to the extent permitted by Law, all Persons who at any time prior to the Distribution Effective Time were directors, officers, agents or employees of any member of the Mural Group (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, does hereby remise, release and forever discharge Alkermes and the other members of the Alkermes Group and all Persons who at any time prior to the Distribution Effective Time were shareholders, directors, officers, agents or employees of any member of the Alkermes Group (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, from any and all (A) Mural Liabilities and (B) Liabilities existing or arising: (1) in connection with the implementation of the Separation (including the Distribution); or (2) from actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to the Distribution Effective Time (whether or not such Liabilities cease being contingent, mature, become known, are asserted or foreseen, or accrue, in each case before, at or after the Distribution Effective Time), in each case to the extent relating to, arising out of or resulting from the Oncology Business, the Mural Assets or the Mural Liabilities, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, in each case, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed on or before the Distribution Effective Time, including in connection with the Separation and any of the other transactions contemplated hereunder and under the Ancillary Agreements (such liabilities, the “Mural Released Liabilities”) and in any event shall not, and shall cause its respective Subsidiaries, if any, not to, bring any Action against any member of the Alkermes Group in respect of any Mural Released Liabilities; provided, however, that for purposes of this Section 6.1(a)(ii), the members of the Mural Group shall also release and discharge any officers or other employees of any member of the Alkermes Group, to the extent

36

any such officers or employees served as directors or officers of any member of the Mural Group prior to the Distribution, from any and all Liabilities or responsibilities for any and all past actions or failures to take action, in each case in their respective capacities as directors or officers, as the case may be, of any such member of the Mural Group, prior to the Distribution Effective Time. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to limit Mural, any member of the Mural Group, or their respective Affiliates from commencing any Actions against any Alkermes officer, director, agent or employee, or their respective heirs, executors, administrators, successors and assigns, with regard to matters arising from, or relating to criminal acts by any such officers, directors, agents or employees.

(b) Nothing contained in this Agreement, including Section 6.1(a) or Section 2.8, shall impair or otherwise affect any right of any Party and, as applicable, a member of such Party’s Group, as well as their respective heirs, executors, administrators, successors and assigns, to enforce this Agreement, any Ancillary Agreement or any agreements, arrangements, commitments or understandings contemplated in this Agreement or in any Ancillary Agreement to continue in effect after the Distribution Effective Time. In addition, nothing contained in Section 6.1(a) shall:

(i) release any Person from any Liability Assumed, Transferred or expressly assigned to a Party or a member of such Party’s Group pursuant to or as contemplated by, or any other Liability of any member of such Group under, this Agreement or any Ancillary Agreement including (A) with respect to Alkermes, any Alkermes Retained Liability, (B) with respect to Mural, any Mural Liability, (C) any Liability expressly preserved pursuant to Section 2.8 and (D) any Liability that the Parties may have with respect to indemnification or contribution pursuant to this Agreement or any Ancillary Agreement or otherwise for Actions brought against the Parties by Third Parties, which Liability shall be governed by the provisions of this Agreement and, in particular, this Article VI and, if applicable, the appropriate provisions of the Ancillary Agreements;

(ii) release any Person from any Liability provided for in or resulting from any other Contract or understanding that is entered into after the Distribution Effective Time between any Party (and/or a member of such Party’s Group), on the one hand, and the other Party (and/or a member of such Party’s Group), on the other hand;

(iii) release any Person other than the Persons released in Section 6.1(a); or

(iv) release any employee of Mural from any Contract with any member of the Alkermes Group to the extent related to the Alkermes Retained Assets, Alkermes Retained Liabilities or Neuroscience Business.

In addition, nothing contained in Section 6.1(a) shall release Alkermes from indemnification or contribution with respect to any director, officer or employee of Mural who was a director, officer or employee of Alkermes or any of its Affiliates prior to the Distribution Effective Time, as the case may be, with respect to which he or she was entitled to such indemnification or contribution pursuant to an obligation existing immediately prior to the Distribution Effective Time; it being understood that if the underlying obligation giving rise to such Action is established by a court of competent jurisdiction to be a Mural Liability, Mural shall indemnify Alkermes for such Liability (including Alkermes’ costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article VI.

37

(c) Each Party shall not, and shall not permit any member of its Group to, make any claim for offset, or commence any Action, including any claim of contribution or any indemnification, against any other Party or any member of any other Party’s Group, or any other Person released pursuant to Section 6.1(a), with respect to any Liabilities released pursuant to Section 6.1(a). If any Person associated with a Party (including any director, officer or employee of a Party) initiates any Action with respect to claims released by this Section 6.1, the Party with which such Person is associated shall be responsible for the reasonable fees and expenses of counsel of the other Party and/or the members of such Party’s Group, as applicable, and such other Party shall be indemnified for all Liabilities incurred in connection with such Action in accordance with the provisions set forth in this Article VI.

(d) Each Party acknowledges that the foregoing releases include a release of any rights and benefits with respect to the Liabilities described therein that such Party and each member of such Party’s Group, and their respective successors and assigns, now has or in the future may have conferred upon them by virtue of any statute or common law principle which provides that a general release does not extend to claims which a Party does not know or suspect to exist in its favor at the time of executing the release. In this connection, each Party hereby acknowledges that it is aware that factual matters now unknown to it may have given or may hereafter give rise to Liabilities that are presently unknown, unanticipated and unsuspected, and it further agrees that the foregoing releases have been negotiated and agreed upon in light of that awareness.

Section 6.2 Indemnification by Alkermes. In addition to any other provisions of this Agreement requiring indemnification and except as otherwise specifically set forth in any provision of this Agreement or of any Ancillary Agreement, following the Distribution Effective Time, Alkermes shall and shall cause the other members of the Alkermes Group to indemnify, hold harmless and defend the Mural Indemnitees from and against any and all Indemnifiable Losses of the Mural Indemnitees to the extent relating to, arising out of, by reason of or otherwise in connection with (a) the Alkermes Retained Liabilities, including the failure of any member of the Alkermes Group or any other Person to pay, perform or otherwise discharge any Alkermes Retained Liability in accordance with its respective terms, whether arising prior to, on or after the Distribution Effective Time, or (b) any breach by Alkermes of any provision of this Agreement or any Ancillary Agreement unless such Ancillary Agreement expressly provides for separate indemnification therein, in which case any such indemnification claims shall be made thereunder (each, a “Mural Claim”).

Section 6.3 Indemnification by Mural. In addition to any other provisions of this Agreement requiring indemnification and except as otherwise specifically set forth in any provision of this Agreement or of any Ancillary Agreement, following the Distribution Effective Time, Mural shall and shall cause the other members of the Mural Group to indemnify, hold harmless and defend the Alkermes Indemnitees from and against any and all Indemnifiable Losses of the Alkermes Indemnitees to the extent relating to, arising out of, by reason of or otherwise in connection with (a) the Mural Liabilities, including the failure of any member of the

38

Mural Group or any other Person to pay, perform or otherwise discharge any Mural Liability in accordance with its respective terms, whether prior to, on or after the Distribution Effective Time, or (b) any breach by Mural of any provision of this Agreement or any Ancillary Agreement unless such Ancillary Agreement expressly provides for separate indemnification therein, in which case any such indemnification claims shall be made thereunder (each, an “Alkermes Claim”).

Section 6.4 Procedures for Indemnification.

(a) Other than with respect to Third Party Claims, which shall be governed by Section 6.4(b):

(i) if a Mural Indemnitee has made a determination that it is or may be entitled to indemnification in respect of any Mural Claim, the Mural Indemnitee shall so notify Alkermes as promptly as reasonably practicable after becoming aware of the existence of such Mural Claim; and

(ii) if an Alkermes Indemnitee has made a determination that it is or may be entitled to indemnification in respect of any Alkermes Claim, the Alkermes Indemnitee shall so notify Mural as promptly as reasonably practicable after becoming aware of the existence of such Alkermes Claim (any such claim made pursuant to Section 6.4(a)(i) or this Section 6.4(a)(ii), a “Direct Claim”).

Each such notice shall be in writing and shall describe in reasonable detail the basis for the claim for indemnification hereunder and set forth, to the extent known, the estimated amount of Indemnifiable Losses for which indemnification may be sought hereunder relating to such claim (including, to the extent practicable, the method of computation thereof); provided, however, that the failure to provide such written notice shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually materially prejudiced as a result of such failure. The Indemnifying Party will have a period of thirty (30) days after receipt of any such notice under this Section 6.4(a) to respond to the claimant thereto. If the Indemnifying Party fails to respond within such period, the claim specified in such notice from the Indemnitee shall be conclusively determined to be an indemnifiable claim for which the Indemnifying Party shall be liable to the applicable Indemnitee(s) hereunder.

(b) If a claim or demand is made against an Indemnitee by any Third Party (a “Third Party Claim”) as to which such Indemnitee is or may be entitled to indemnification pursuant to this Agreement, Alkermes (on behalf of the Alkermes Indemnitees) or Mural (on behalf of the Mural Indemnitees), as applicable (such claimant, the “Claiming Party”), shall notify the Indemnifying Party of the Third Party Claim in writing and in reasonable detail describing the basis for any claim for indemnification hereunder, referring to the provisions of this Agreement or any Ancillary Agreement in respect of which such right of indemnification is claimed by such Indemnitee or arises and including copies of all Third Party written notices and documents received by the Claiming Party (and any or all of its Indemnitees) relating to the Third Party Claim promptly (and in any event within twenty (20) days) after receipt by such Indemnitee of written notice of the Third Party Claim; provided, however, that the failure to

39

provide notice of any such Third Party Claim pursuant to this sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually materially prejudiced as a result of such failure. Thereafter, the Claiming Party shall deliver to the Indemnifying Party, promptly (and in any event within five (5) Business Days) after the receipt thereof by the Claiming Party (or any of its Indemnitees), copies of any and all additional Third Party written notices and documents (including court papers) received by the Claiming Party (or any of its Indemnitees) relating to the Third Party Claim.

(c) Subject to the provisions of this Section 6.4(c), the Indemnifying Party has the right, exercisable by written notice to the Claiming Party within thirty (30) days after receipt of notice from the Claiming Party pursuant to Section 6.4(b), to assume and conduct the defense (including, subject to the conditions of this Section 6.4(c), settlement) of such Third Party Claim in accordance with the limits set forth in this Agreement with counsel selected by the Indemnifying Party and reasonably acceptable to the applicable Indemnitees. If the Indemnifying Party does not assume the defense of a Third Party Claim in accordance with this Section 6.4(c), the Indemnitee may defend the Third Party Claim. If the Indemnifying Party has assumed the defense of a Third Party Claim as provided in this Section 6.4(c), the Indemnifying Party shall not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense of the Third Party Claim; provided, however, that if (w) in the reasonable judgment of the Indemnitee, after consultation with outside counsel, there exists a conflict of interest between the Indemnifying Party and the applicable Indemnitee(s) in the defense of such Third Party Claim by the Indemnifying Party, (x) the party making such Third Party Claim is a Governmental Entity with regulatory or other authority over the Indemnitee or any of its material assets, (y) the Third Party Claim seeks injunctive or other non-monetary relief that, if granted, would reasonably be expected to have a material and adverse effect on the Indemnitee’s business or (z) the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim, the Indemnitee may assume its own defense, and the Indemnifying Party shall be liable for all reasonable costs or expenses paid or incurred in connection with such defense; provided that the Indemnifying Party shall not be responsible for the expenses of more than one counsel for all Indemnitees with respect to the same Third Party Claim or related Third Party Claims (plus one local counsel in any jurisdiction within which such Third Party Claim has been brought). The Indemnifying Party or the Indemnitee, as the case may be, has the right to participate in (but, subject to the prior sentence, not control), at its own expense, the defense of any Third Party Claim that the other Person is defending as provided in this Agreement. The Indemnifying Party, if it has assumed the defense of any Third Party Claim as provided in this Agreement, may not, without the prior written consent of the Indemnitee (not to be unreasonably withheld, conditioned or delayed), consent to a settlement or compromise of, or the entry of any judgment arising from, any such Third Party Claim. The Indemnitee may consent to a settlement or compromise of, or the entry of any judgment arising from, any Third Party Claim, the defense of which has not been assumed by the Indemnifying Party, only with the prior written consent of the Indemnifying Party, not to be unreasonably withheld, conditioned or delayed.

40

(d) The Claiming Party and the Indemnifying Party shall (and the Claiming Party shall cause the applicable Indemnitee(s) to) make reasonably available to each other and their respective agents and representatives all relevant records available to them that are necessary or appropriate for the defense of any Third Party Claim, subject to any bona fide claims of attorney-client privilege, and each of the Indemnifying Party and the Claiming Party shall use its reasonable efforts to assist, and to cause the employees and counsel of such party to assist, in the defense of such Third Party Claim. If a Party asserts its right to participate in the defense and investigation of any Third Party Claim, the Party controlling the defense and investigation of such Third Party Claim shall act in good faith and reasonably consult and cooperate with the Indemnitee or the Indemnifying Party, as the case may be, in connection with any appearances, briefs, arguments and proposals made or submitted by or on behalf of any party in connection with the Third Party Claim (including considering in good faith all reasonable additions, deletions or changes suggested by the Indemnitee or the Indemnifying Party, as the case may be, in connection with any filings made with any Governmental Entity or proposals to the Third Party claimant in connection therewith). With respect to any Third Party Claim that implicates both Parties in any material respect due to the allocation of Liabilities, responsibilities for management of defense and related indemnities pursuant to this Agreement or any of the Ancillary Agreements, the Parties agree to use commercially reasonable efforts to cooperate fully and maintain a joint defense (in a manner that, to the extent reasonably practicable, will preserve for all Parties any Privilege with respect thereto). The Party that is not responsible for managing the defense of any such Third Party Claim shall, upon reasonable request, be consulted with respect to significant matters relating thereto and may, if necessary or helpful, retain counsel to assist in the defense of such claims. Notwithstanding the foregoing, nothing in this Section 6.4(d) shall derogate from a Party’s right to control the defense of any Action in accordance with Section 6.4.

(e) Each of the Parties agrees that at all times from and after the Distribution Effective Time, if an Action is commenced by a Third Party naming two (2) or more Parties (or any member of such Parties’ respective Groups) as defendants and with respect to which one or more named Parties (or any member of such Party’s Group) is a nominal defendant and/or such Action is related solely to an Asset or Liability that the other Party has been assigned under this Agreement, any Ancillary Agreement or any Third Party Agreement, then the other Party or Parties shall use commercially reasonable efforts to cause such nominal defendant to be removed from such Action, as soon as reasonably practicable.

(f) The provisions of this Section 6.4 (other than this Section 6.4(f)) and Section 6.7 (other than Section 6.7(g)) shall not apply to Taxes (Taxes being governed by the Tax Matters Agreement).

Section 6.5 Indemnification Obligations Net of Insurance Proceeds and Other Amounts.

(a) Any recovery by any Party (including any of its Indemnitees) for any Indemnifiable Loss subject to indemnification pursuant to this Article VI shall be calculated (i) net of Insurance Proceeds actually received by such Party (or any of its Indemnitees) with respect to any Indemnifiable Loss and (ii) net of any proceeds actually received by such Party (or any of its Indemnitees) from any Third Party with respect to any such Liability corresponding to the Indemnifiable Loss (“Third Party Proceeds”), in the case of (i) and (ii) net of the costs of collection thereof and any increase in premium attributable thereto under applicable Third Party Policies. Accordingly, the amount which any Indemnifying Party is required to pay pursuant to

41

this Article VI to any Indemnitee pursuant to this Article VI shall be reduced by any Insurance Proceeds or Third Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee corresponding to the related Indemnifiable Loss. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party corresponding to any Indemnifiable Loss (an “Indemnity Payment”) and subsequently receives Insurance Proceeds or Third Party Proceeds, then the Indemnitee shall pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or Third Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

(b) The Parties hereby agree that an insurer or other Third Party that would otherwise be obligated to pay any amount shall not be relieved of the responsibility with respect thereto or have any subrogation rights with respect thereto by virtue of any provision contained in this Agreement or any Ancillary Agreement, and that no insurer or any other Third Party shall be entitled to a “windfall” (e.g., a benefit they would not otherwise be entitled to receive, or the reduction or elimination of an insurance coverage obligation that they would otherwise have, in the absence of the indemnification or release provisions) by virtue of any provision contained in this Agreement or any Ancillary Agreement. Each Party shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to collect or recover, or allow the Indemnifying Party to collect or recover, or cooperate with each other in collecting or recovering, any Insurance Proceeds that may be collectible or recoverable respecting the Liabilities for which indemnification may be available under this Article VI. Notwithstanding the foregoing, an Indemnifying Party may not delay making any indemnification payment required under the terms of this Agreement, or otherwise satisfying any indemnification obligation, pending the outcome of any Actions to collect or recover Insurance Proceeds, and an Indemnitee need not attempt to collect any Insurance Proceeds prior to making a claim for indemnification or receiving any Indemnity Payment otherwise owed to it under this Agreement or any Ancillary Agreement.

Section 6.6 Contribution. If the indemnification provided for in this Article VI is unavailable for any reason to an Indemnitee (other than failure to provide notice with respect to any Third Party Claims in accordance with Section 6.4(b)) in respect of any Indemnifiable Loss, then the Indemnifying Party shall, in accordance with this Section 6.6, contribute to the Indemnifiable Losses incurred, paid or payable by such Indemnitee as a result of such Indemnifiable Loss in such proportion as is appropriate to reflect the relative fault of Mural and each other member of the Mural Group, on the one hand, and Alkermes and each other member of the Alkermes Group, on the other hand, in connection with the circumstances which resulted in such Indemnifiable Loss. Solely for purposes of determining relative fault pursuant to this Section 6.6: (i) any fault associated with information contained in the Distribution Disclosure Documents shall be deemed to be allocated to Mural and the other members of the Mural Group (other than as set forth in the definition of Excluded Liabilities); (ii) any fault associated with the conduct of the Neuroscience Business prior to the Distribution Effective Time shall be deemed to be allocated to Alkermes and the other members of the Alkermes Group, and no such fault shall be deemed to be the fault of Mural or any other member of the Mural Group; and (iii) any fault associated with the conduct of the Oncology Business prior to the Distribution Effective Time shall be deemed to be the fault of Mural and the other members of the Mural Group, and no such fault shall be deemed to be the fault of Alkermes or any other member of the Alkermes Group.

42

Section 6.7 Additional Matters; Survival of Indemnities.

(a) The agreements contained in this Article VI shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee; and (ii) the knowledge by the Indemnitee of Indemnifiable Losses for which it might be entitled hereunder. The agreements contained in this Article VI shall survive the Distribution.

(b) The rights and obligations of each Party and their respective Indemnitees under this Article VI shall survive (i) the sale or other Transfer by any Party or its respective Subsidiaries of any Assets or businesses or the assignment by it of any Liabilities and (ii) any merger, consolidation, business combination, sale of all or substantially all of the Assets, restructuring, recapitalization, reorganization or similar transaction involving either Party or any of its Subsidiaries.

(c) Except to the extent set forth in any Ancillary Agreement, absent fraud or willful misconduct by an Indemnifying Party, the provisions of this Article VI shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or losses resulting from any breach of this Agreement or any Ancillary Agreement and each Indemnitee expressly waives and relinquishes any and all rights, claims or remedies such Person may have with respect to the foregoing other than under this Article VI against any Indemnifying Party.

(d) Notwithstanding the foregoing, to the extent any Ancillary Agreement provides procedures for indemnification or contribution that differ from the provisions set forth in this Article VI, the terms of the Ancillary Agreement will govern.

(e) Any amounts payable pursuant to this Article VI shall be paid without duplication, and in no event shall any Party receive any payment in respect of an Indemnifiable Loss or receive contribution under different provisions of any Ancillary Agreement in respect of the same Liabilities.

(f) Any amount to be paid or reimbursed by an Indemnifying Party (or a member of such Party’s Group) to an Indemnitee pursuant to this Article VI shall be paid in accordance with the procedures set forth in Section 10.11.

(g) For all Tax purposes, the Parties agree to treat (i) any payment required by this Agreement (other than payments with respect to interest accruing after the Effective Time) by (x) Alkermes to Mural as a tax-free contribution by Alkermes to Mural with respect to Mural Ordinary Shares occurring immediately before the Effective Time or (y) Mural to Alkermes as a distribution by Mural to Alkermes with respect to Mural Ordinary Shares occurring immediately before the Effective Time, or as a payment of an assumed or retained Liability; and (ii) any payment of interest as taxable or deductible, as the case may be, to the Party entitled under this Agreement to retain such payment or required under this Agreement to make such payment, in either case except as otherwise required by a Final Determination (as such term is defined in the Tax Matters Agreement).

43

ARTICLE VII

PRESERVATION OF RECORDS; ACCESS TO INFORMATION;

CONFIDENTIALITY; PRIVILEGE

Section 7.1 Preservation of Information.

(a) Except as otherwise required or agreed in writing, or as otherwise provided in any Ancillary Agreement, with regard to any information referenced in Section 7.3, each Party shall use its commercially reasonable efforts, at its sole cost and expense, to retain such information, until the latest of, as applicable, (i) the date on which such information is no longer required to be retained pursuant to Alkermes’ applicable record retention policy as in effect immediately prior to the Distribution, including pursuant to any “Litigation Hold” issued by Alkermes or any of its Subsidiaries prior to the Distribution, (ii) the concluding date of any period as may be required by any applicable Law, (iii) the concluding date of any period during which such information relates to a pending or threatened Action which is known to the members of the Alkermes Group or Mural Group, as applicable, in possession of such information at the time any retention obligation with regard to such information would otherwise expire, and (iv) the concluding date of any period during which the destruction of such information could interfere with a pending or threatened investigation by a Governmental Entity which is known to the members of the Alkermes Group or Mural Group, as applicable, in possession of such information at the time any retention obligation with regard to such information would otherwise expire; provided, that with respect to any pending or threatened Action arising after the Distribution, clause (iii) of this sentence applies only to the extent that whichever member of the Alkermes Group or Mural Group, as applicable, is in possession of such information has been notified in writing pursuant to a “Litigation Hold” by the other Party of the relevant pending or threatened Action. The Parties agree that upon written request from either Party that certain information relating to the Oncology Business, the Neuroscience Business or the transactions contemplated hereby be retained in connection with an Action, the other Party shall use reasonable efforts to preserve and not to destroy or dispose of such information without the consent of the requesting Party.

(b) Alkermes and Mural intend that any transfer of information that would otherwise be within the attorney-client or attorney work product privileges not operate as a waiver of any potentially applicable privilege.

Section 7.2 Financial Statements and Accounting.

(a) From the Distribution Effective Time until the completion of each Party’s audit for the fiscal year ending December 31, 2023, each Party agrees to provide reasonable assistance and, subject to Section 7.7, reasonable access to its properties, books and records, other information in its possession and control and personnel, and to use its commercially reasonable efforts to cooperate with the other Party’s requests, in each case to enable (i) such other Party to meet its timetable for dissemination of its earnings releases, financial statements and management’s assessment of the effectiveness of its disclosure controls and procedures and its internal control over financial reporting in accordance with Items 307 and 308, respectively, of Regulation S-K, (ii) such other Party’s accountants to timely complete their review of the quarterly financial statements and audit of the annual financial statements of such other Party,

44

including, to the extent applicable to such Party, its auditor’s audit, if applicable, of its internal control over financial reporting and management’s assessment thereof in accordance with Section 404 of the Sarbanes-Oxley Act of 2002 and the Commission’s and Public Company Accounting Oversight Board’s rules and auditing standards thereunder and (iii) such other Party to respond to any written request or official comment from a Governmental Entity, including in connection with responding to a comment letter from the Commission; provided, that, in connection with this clause (iii), each Party shall provide reasonable access on the terms set forth in this Section 7.2 for a period of three (3) years following the Distribution Date. For the avoidance of doubt, this Section 7.2(a) shall not limit in any manner the obligations of the Parties under any Ancillary Agreement.

(b) Nothing in this Article VII shall require any Party to violate any agreement with any Third Party regarding the confidentiality of information relating to that Third Party or its business (except as may be required by law); provided, however, that in the event that a Party is required under this Section 7.2 to disclose any such information, such Party shall use commercially reasonable efforts to seek to obtain such Third Party’s prior written consent to the disclosure of such information.

Section 7.3 Provision of Information. Other than in circumstances in which indemnification is sought pursuant to Article VI (in which event the provisions of such Article VI shall govern) or for matters related to provision of Tax records (in which event the provisions of the Tax Matters Agreement shall govern), and subject to appropriate restrictions for Privileged Information or Confidential Information:

(a) From and after the Distribution Effective Time, and subject to compliance with the terms of the Ancillary Agreements (including Section 4.1 of each of the Alkermes Transition Services Agreement and the Mural Transition Services Agreement), upon the prior written reasonable request by, and at the expense of, Mural for specific and identified: (i) information that relates to Mural or the Oncology Business, as the case may be, prior to the Distribution Effective Time; (ii) information that is necessary for Mural or a member of the Mural Group to comply with the terms of, or otherwise perform under, any Shared Contract or Ancillary Agreement to which Alkermes and/or Mural, or a member of their respective Groups, are parties; (iii) copies of Alkermes templates and form documents used in the operation of the Oncology Business; (iv) information that is otherwise required by Mural with regard to reasonable compliance with reporting, disclosure, filing or other requirements imposed on Mural (including under applicable securities laws) by a Governmental Entity having jurisdiction over Mural; or (v) information that is otherwise for use in any other judicial, regulatory, administrative or other proceeding or in order to satisfy audit, accounting, claims, regulatory, Action or other similar requirements, as applicable, Alkermes shall provide, as soon as reasonably practicable following the receipt of such request, appropriate access or, to the extent such information is reasonably practicable to identify and extract, copies of such information, templates or forms (or the originals thereof if Mural has a reasonable need for such originals) in the possession or control of Alkermes or any of its Subsidiaries, but only to the extent such items so relate and are not already in the possession or control of Mural or any of its Subsidiaries; provided, that, to the extent any originals are delivered to Mural pursuant to this Agreement, a Shared Contract or the Ancillary Agreements, Mural shall, at its own expense, return them to Alkermes within a reasonable time after the need to retain such originals has ceased; and

45

provided further, that, in the event that Alkermes, in its sole and absolute discretion, determines that any such access or the provision of any such information, templates or forms (including information requested under Section 7.2) would violate any Law or Contract with a Third Party or waive any Privilege, Alkermes shall not be obligated to provide such information requested by Mural (provided, that Alkermes shall use commercially reasonable efforts to permit compliance with its obligations under this Section 7.3 in a manner that avoids any such consequence). Notwithstanding the foregoing, Alkermes shall not be obligated to provide any requested information pursuant to clause (iv) or (v) above following the date that is the fifth anniversary of the Distribution Date (or such later time or times as the Parties may agree).

(b) From and after the Distribution Effective Time, and subject to compliance with the terms of the Ancillary Agreements (including Section 4.1 of each of the Alkermes Transition Services Agreement and the Mural Transition Services Agreement), upon the prior written reasonable request by, and at the expense of, Alkermes for specific and identified information that: (i) relates to Alkermes or the Neuroscience Business, as the case may be, prior to the Distribution Effective Time; (ii) is necessary for Alkermes or a member of the Alkermes Group to comply with the terms of, or otherwise perform under, any Shared Contract or Ancillary Agreement to which Alkermes and/or Mural, or a member of their respective Groups, are parties; (iii) is otherwise required by Alkermes with regard to reasonable compliance with reporting, disclosure, filing or other requirements imposed on Alkermes (including under applicable securities laws) by a Governmental Entity having jurisdiction over Alkermes; or (iv) is otherwise for use in any other judicial, regulatory, administrative or other proceeding or in order to satisfy audit, accounting, claims, regulatory, Action or other similar requirements, as applicable, Mural shall provide, as soon as reasonably practicable following the receipt of such request, appropriate access or, to the extent such information is reasonably practicable to identify and extract, copies of such information (or the originals thereof if Alkermes has a reasonable need for such originals) in the possession or control of Mural or any of its Subsidiaries, but only to the extent such items so relate and are not already in the possession or control of Alkermes or any of its Subsidiaries; provided, that, to the extent any originals are delivered to Alkermes pursuant to this Agreement, a Shared Contract or the Ancillary Agreements, Alkermes shall, at its own expense, return them to Mural within a reasonable time after the need to retain such originals has ceased; and provided, further that, in the event that Mural, in its sole and absolute discretion, determines that any such access or the provision of any such information (including information requested under Section 7.2) would violate any Law or Contract with a Third Party or waive any Privilege, Mural shall not be obligated to provide such information requested by Alkermes (provided, that Mural shall use commercially reasonable efforts to permit compliance with its obligations under this Section 7.3 in a manner that avoids any such consequence). Notwithstanding the foregoing, Mural shall not be obligated to provide any requested information pursuant to clause (iii) or (iv) above following the date that is the fifth anniversary of the Distribution Date (or such later time or times as the Parties may agree).

(c) In connection with the provision of information under this Section 7.3, the providing Party shall be entitled to redact any portion of the information to the extent related to any matter other than the receiving Party’s business. Each of Alkermes and Mural agree to make their respective personnel available during regular business hours to discuss the information exchanged pursuant to this Section 7.3.

46

Section 7.4 Limitations of Liability. Neither Party shall have any Liability to the other Party in the event that any information exchanged or provided pursuant to this Agreement is found to be inaccurate in the absence of gross negligence, bad faith or willful misconduct by the Party providing such information. Neither Party shall have any Liability to any other Party if any information is destroyed after commercially reasonable efforts by such Party to comply with the provisions of Section 7.1.

Section 7.5 Witness Services; Cooperation. At all times from and after the Distribution Effective Time, each of Alkermes and Mural shall use its commercially reasonable efforts to make available to the other Party, upon reasonable written request, its and its Subsidiaries’ officers, directors, employees and agents (taking into account the business demands of such individuals) as witnesses to the extent that (i) such Persons may reasonably be required to testify in connection with the prosecution or defense of any Action in which the requesting Party may from time to time be involved (except for claims, demands or Actions in which one or more members of one Group is adverse to one or more members of the other Group) and (ii) there is no conflict in the Action between the requesting Party and the other Party. Notwithstanding any provisions of Article VII to the contrary, after the Distribution Effective Time, each Party shall use commercially reasonable efforts to assist (or cause the other members of its Group to assist) the other with respect to any Action or potential Action upon the request of such other Party; provided, that any such expenses incurred in connection therewith shall be at such other Party’s sole expense.

Section 7.6 Reimbursement; Other Matters. Except to the extent otherwise contemplated by this Agreement or any Ancillary Agreement, a Party providing information, access to information or services to the other Party pursuant to this Article VII shall be entitled to receive from the recipient, upon the presentation of invoices therefor, payments for such amounts, relating to supplies, disbursements and other out-of-pocket expenses (which shall not include the costs of salaries and benefits of employees of such Party or any pro rata portion of overhead or other costs of employing such employees which would have been incurred by such employees’ employer regardless of the employees’ service with respect to the foregoing), as may be reasonably incurred and properly paid under applicable Law in providing such information, access to such information or services.

Section 7.7 Confidentiality.

(a) Except as otherwise provided herein, in any Ancillary Agreement, or in any Contract between a Party or its Subsidiaries, on the one hand, and their respective employees, on the other hand, each of Alkermes and Mural shall hold, and shall cause the other members of their respective Groups and their respective Representatives to hold, in strict confidence, with at least the same degree of care that applies to Alkermes’ Confidential Information pursuant to policies and procedures in effect as of the Distribution Effective Time, and not disclose or release, or permit or cause to be disclosed or released, any Confidential Information of the other Party that is either in the first Party’s possession (including Confidential Information in its possession prior to the Distribution Effective Time) or furnished by the other Party or any member of its Group or their respective Representatives at any time pursuant to this Agreement or any Ancillary Agreement, and shall not use any such Confidential Information other than for such purposes as may be expressly permitted hereunder (including under

47

Section 2.4) or under any Ancillary Agreement. If any Confidential Information is disclosed to any member of the other Party’s Group in connection with providing services to any member of such first Party’s Group under this Agreement or any Ancillary Agreement, then such disclosed Confidential Information shall be used by the applicable member of such other Party’s Group only as required to provide such services.

(b) Notwithstanding anything to the contrary in this Section 7.7, each Party may disclose, or may permit disclosure of, the other Party’s Confidential Information: (i) to its Representatives who have a need to know such information for non-commercial purposes and are informed of the obligation to hold such information confidential and in respect of whose failure to comply with such obligations, the first Party will be responsible or (ii) if any Party or any other member of its Group is required or requested to disclose any such Confidential Information by judicial or administrative process or by other requirements of Law or stock exchange rule or is advised by outside counsel in connection with an Action brought by a Governmental Entity that it is advisable to do so. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made by a Third Party pursuant to clause (ii) above, each Party, as applicable, shall promptly notify (to the extent permissible by Law) the Party to whom the Confidential Information relates of the existence of such requirement or request and shall provide such affected Party a reasonable opportunity to seek an appropriate protective order or other remedy, which such Party (at the expense of the other Party) will cooperate in obtaining to the extent reasonably practicable. In the event that such appropriate protective order or other remedy is not obtained, the Party which faces the disclosure requirement shall furnish only that portion of the Confidential Information that is required to be disclosed and shall take commercially reasonable steps to ensure that confidential treatment is accorded such Confidential Information.

(c) Each of Alkermes and Mural shall inform their respective Representatives who have or have access to the other Party’s Confidential Information of their obligation to hold such information confidential in accordance with the provisions of this Agreement.

(d) Without limiting the foregoing, when any Confidential Information is no longer needed for the purposes contemplated by this Agreement or any Ancillary Agreement, each Party shall, at its option and as promptly as practicable after receiving a written request from the other Party, either (i) return to such other Party all such information in a tangible form (including all copies thereof and all notes, extracts or summaries based thereon) or (ii) certify to such other Party that the first Party has destroyed such information (and such copies thereof and such notes, extracts or summaries based thereon); provided, that such first Party’s Representatives may retain one (1) copy of such information to the extent required by applicable Law or professional standards, and shall not be required to destroy any such information located in back-up, archival electronic storage; and provided, further, that any such information so retained shall remain subject to the confidentiality and non-use provisions of this Agreement or any Ancillary Agreement.

48

(e) Each Party acknowledges that it and its respective Subsidiaries may presently have and, following the Distribution Effective Time, may gain access to or possession of confidential or proprietary information of, or personal information relating to, Third Parties (i) that was received under confidentiality or non-disclosure agreements entered into between such Third Parties, on the one hand, and the other Party (or another member of its Group), on the other hand, prior to the Distribution Effective Time; or (ii) that, as between the two Parties, was originally collected by the other Party (or another member of its Group) and that may be subject to and protected by privacy, data protection or other applicable Laws. Each Party agrees that it shall hold, protect and use, and shall cause the other members of its Group and its and their respective Representatives to hold, protect and use, in strict confidence the confidential and proprietary information of, or personal information relating to, Third Parties in accordance with privacy, data protection or other applicable Laws and the terms of any agreements that were either entered into before the Distribution Effective Time or affirmative commitments or representations that were made before the Distribution Effective Time by, between or among the other Party (or other member(s) of its Group), on the one hand, and such Third Parties, on the other hand.

(f) For the avoidance of doubt and notwithstanding any other provision of this Section 7.7, (i) the sharing of Privileged Information shall be governed solely by Section 7.8, and (ii) information that is subject to any confidentiality provision or other disclosure restriction in any Ancillary Agreement shall be governed by the terms of such Ancillary Agreement.

Section 7.8 Privilege Matters.

(a) The Parties recognize that legal and other professional services that have been and will be provided prior to the Distribution Effective Time have been and will be rendered for the benefit of Alkermes and its Subsidiaries, including, as applicable, the members of the Mural Group. Accordingly, with respect to such pre-Distribution services, the Parties agree as follows:

(i) (A) Alkermes shall be entitled, in perpetuity, to control the assertion or waiver of Privilege in connection with any Privileged Information that relates solely to the Neuroscience Business, whether or not the Privileged Information is in the possession or under the control of a member of the Alkermes Group or the Mural Group and (B) Alkermes shall also be entitled, in perpetuity, to control the assertion or waiver of Privilege in connection with any Privileged Information that relates solely to any Alkermes Retained Liabilities, whether or not the Privileged Information is in the possession or under the control of a member of the Alkermes Group or the Mural Group;

(ii) (A) Mural shall be entitled, in perpetuity, to control the assertion or waiver of Privilege in connection with any Privileged Information that relates solely to the Oncology Business, whether or not the Privileged Information is in the possession or under the control of a member of the Mural Group or the Alkermes Group and (B) Mural shall also be entitled, in perpetuity, to control the assertion or waiver of Privilege in connection with any Privileged Information that relates solely to any Mural Liabilities, whether or not the Privileged Information is in the possession or under the control of a member of the Mural Group or the Alkermes Group;

(iii) If Alkermes and Mural in good faith do not agree as to whether certain information is Privileged Information, or whether certain Privileged Information is subject to Section 7.8(a)(i) or Section 7.8(a)(ii), then the information shall be treated as Shared Privileged Information subject to Section 7.8(b);

49

(iv) Mural agrees that it shall not (and shall cause the members of its Group not to) waive, or allege or purport to waive, any Privilege which could be asserted under any applicable Law, and in which Alkermes (or any member of its Group) may have a Privilege, without the written consent of Alkermes; and

(v) Alkermes agrees that it shall not (and shall cause the members of its Group not to) waive, or allege or purport to waive, any Privilege which could be asserted under any applicable Law, and in which Mural (or any member of its Group) may have a Privilege, without the written consent of Mural.

(b) The Parties agree that they shall have an equal right with respect to all Privileges related to legal and other professional services that have been and will be provided prior to the Distribution Effective Time not allocated pursuant to Section 7.8(a). With respect to such pre-Distribution services and related Privileged Information (“Shared Privileged Information”), the Parties agree as follows:

(i) Shared Privileged Information shall be subject to a shared Privilege among such Parties involved, or having an interest, in the claims, proceedings, litigation, disputes or other matters at issue;

(ii) No Party may (or cause or permit any member of its Group to) waive, or allege or purport to waive, any Privilege which could be asserted under any applicable Law with respect to Shared Privileged Information, without the written consent of the other Party, which shall not be unreasonably withheld, conditioned or delayed;

(iii) If a dispute arises between or among the Parties or their respective Group members regarding whether a Privilege should be waived to protect or advance the interest of any Party (or members of its Group) with respect to Shared Privileged Information, each Party agrees that it shall negotiate in good faith, shall endeavor to minimize any prejudice to the rights of the other Party and members of its Group, and shall not unreasonably withhold consent to any request for waiver by the other Party, and each Party specifically agrees that it shall not withhold consent to waive for any purpose except in good faith to protect the legitimate interests of its Group; and

(iv) If, within fifteen (15) Business Days of a Party’s providing a written request to the other Party to waive a Privilege over Shared Privileged Information, the Parties have not succeeded in negotiating a resolution to any dispute regarding whether the Privilege should be waived with respect to such Shared Privileged Information, and the requesting Party determines that a Privilege should nonetheless be waived to protect or advance the legitimate interests of its Group, the requesting Party shall provide the objecting Party fifteen (15) Business Days’ written notice prior to effecting such waiver. Each Party specifically agrees that failure within fifteen (15) Business Days of receipt of such notice to commence proceedings to enjoin such waiver or seek related relief, pursuant to Section 8.2(d) and under applicable Law, shall be deemed full and effective consent to such waiver. In the event proceedings are commenced as described above, the Parties agree that any such Privilege shall not be waived by either Party until the final determination of such dispute.

50

(c) The Parties agree that Shared Privileged Information shall continue to be held subject to Privilege from disclosure to Third Parties even if adversity of interest may subsequently be discerned or arise between Parties or their respective Group members. Further, in the event a Party or any member of its Group becomes adverse to the other Party or any member of its Group, each Party agrees that it shall not (and shall not cause or permit any member of its Group to) seek to disqualify any law firms who have or have had access to Shared Privileged Information from continuing to represent members of the other Party’s Group, as applicable, solely by having, or having had access to such Shared Privileged Information.

(d) Nothing in this Section 7.8 shall be construed or interpreted to restrict the right or authority of the Parties to enter into any further written agreement concerning Privileged Information.

(e) The transfer of all information pursuant to this Agreement is made in reliance on the agreement of Alkermes or Mural as set forth in Section 7.7 and this Section 7.8, to maintain the confidentiality of Privileged Information, and to assert and maintain any applicable Privilege according to the terms of this Section 7.8. The access to information being granted pursuant to Section 7.2 and Section 7.3, the agreement to provide witnesses and individuals pursuant to Section 7.5, the furnishing of notices and documents and other cooperative efforts contemplated by Section 6.4 and the transfer of Privileged Information between the Parties and the members of their respective Groups pursuant to this Agreement shall not be deemed a waiver of any Privilege that has been or may be asserted under this Agreement or otherwise.

Section 7.9 Conflicts Waiver. Each of the Parties acknowledges, on behalf of itself and each other member of its Group, notwithstanding anything to the contrary contained herein, that each of Alkermes and Mural has retained Goodwin Procter LLP and Arthur Cox LLP (collectively, the “Known Counsel”) to act as its counsel in connection with this Agreement, the Ancillary Agreements and the transactions contemplated hereby and thereby. Following the Separation, it is expected that Alkermes and Mural will continue to retain Known Counsel in connection with this Agreement, the Ancillary Agreements and the transactions contemplated hereby and thereby, among other matters. Alkermes and Mural hereby agree on behalf of each such Party and each member of its respective Group that Known Counsel may continue to represent any member of the Alkermes Group and the Mural Group, respectively, with respect to such matters. Each of Alkermes and Mural, on behalf of itself and each other member of its Group, agrees to take, and to cause their respective then-Affiliates to take, all steps necessary to implement the intent of this Section 7.9. Each of Alkermes and Mural, on behalf of itself and each other member of its Group, further agrees that each Known Counsel and its respective partners and employees are third party beneficiaries of this Section 7.9.

Section 7.10 Ownership of Information. Any information owned by one Party or any of its Subsidiaries that is provided to a requesting Party pursuant to this Article VII shall be deemed to remain the property of the providing Party. Unless expressly set forth herein, nothing contained in this Agreement shall be construed as granting a license or other rights to any Party with respect to any such information, whether by implication, estoppel or otherwise.

51

ARTICLE VIII

DISPUTE RESOLUTION

Section 8.1 Negotiation. A Party seeking resolution of (i) a controversy, dispute or Action arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity or breach of this Agreement or the Ancillary Agreements or otherwise arising out of, or in any way related to, this Agreement or the Ancillary Agreements or the transactions contemplated hereby or thereby, including any Action based on contract, tort, statute or constitution, or (ii) a claim with respect to the inadvertent transfer or omission of an Asset or Liability as contemplated by the definition of “Alkermes Retained Asset,” “Alkermes Retained Liability,” “Mural Asset” or “Mural Liability,” respectively (collectively, “Disputes”), shall provide written notice of such Dispute to the other Party, specifying the terms of such Dispute in reasonable detail (“Dispute Notice”). The appropriate executives of the Parties who have authority to settle the Dispute (or such other individuals designated by the respective executives) shall attempt to resolve the Dispute through good faith negotiation for a reasonable period of time; provided, that such reasonable period shall not, unless otherwise agreed by the Parties in writing, exceed thirty (30) days from the time of receipt by a Party of the Dispute Notice. If the Dispute has not been resolved within fifteen (15) days after receipt of the Dispute Notice, the respective Chief Executive Officers or their respective designees (with full settlement authority) of Alkermes and Mural shall meet in person (or where necessary, by phone) at a mutually acceptable time and, if applicable, place, and thereafter as often as they reasonably deem necessary, to attempt in good faith to resolve the Dispute. Any contractual time period or deadline under this Agreement or any Ancillary Agreement to which such Dispute relates occurring after the Dispute Notice is received shall be tolled from the date in which a dispute is initiated until the conclusion of the arbitration process as outlined in this Article VIII.

Section 8.2 Arbitration.

54

(a) Claims. Any Dispute that is not resolved pursuant to Section 8.1 within thirty (30) days after receipt of a Dispute Notice, unless such thirty (30) day period is otherwise extended by agreement of the Parties in writing, shall be resolved by final and binding arbitration before a panel of three (3) neutral arbitrators with relevant industry experience (the “Arbitrators”). One (1) Arbitrator shall be chosen by Alkermes and one (1) Arbitrator shall be chosen by Mural within forty-five (45) days of receipt of a Dispute Notice, unless such forty-five (45) day period is otherwise extended by agreement of the Parties in writing. The third (3rd) Arbitrator shall be chosen by mutual agreement of the Arbitrator chosen by Alkermes and the Arbitrator chosen by Mural within fifteen (15) days of the date that the last of such Arbitrators was appointed. The arbitration shall be administered by the International Chamber of Commerce (the “Administrator”) in accordance with its then existing arbitrator rules or procedures regarding commercial or business disputes. The arbitration shall be held in Boston, Massachusetts. The Arbitrators shall complete the arbitration hearing within ninety (90) days after selection of the third (3rd) Arbitrator, subject to extension by written agreement executed by both Parties.

(b) Arbitrators’ Award. The Arbitrators shall, within fifteen (15) days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The decision or award rendered by the Arbitrators shall be final, binding, conclusive and non-appealable, and judgment may be entered upon it in accordance with the Laws of the State of Delaware or any other court of competent jurisdiction. The Arbitrators shall be authorized to award compensatory damages, but shall not be authorized (i) to award non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (ii) to award punitive damages, or (iii) to reform, modify or materially change this Agreement or the Ancillary Agreements; provided, however, that the limitations described in the foregoing clauses (i) and (ii) shall not apply if such damages are statutorily imposed.

(c) Costs. Each Party shall bear its own attorney’s fees, costs and disbursements arising out of the arbitration and the costs of the Arbitrator selected by it, and shall pay an equal share of the fees and costs of the third (3rd) Arbitrator and Administrator; provided, however, that the Arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the Administrator and the Arbitrators.

(d) Injunctive or Other Equity Relief. Nothing contained in this Agreement shall deny any Party the right to seek temporary injunctive relief in the context of a bona fide emergency or prospective irreparable harm in order to maintain the status quo while an arbitration initiated pursuant to Article VIII is pending; provided, however, that any other relief not expressly permitted under this Section 8.2(d) must be pursued in accordance with Section 8.2(a), with all remedies being cumulative to the extent allowed by applicable Law. The Parties further agree that irreparable harm would occur, and thus need not be established, in an action to enforce the confidentiality obligations of Section 7.7 or to resolve a privilege dispute under Section 7.8(b)(iv), and that such action may be brought pursuant to this Section 8.2(d). The Parties further agree that any action brought under this Section 8.2(d) shall be brought exclusively in the courts within the State of Delaware set forth in Section 10.16, and that such courts shall have personal jurisdiction over the Parties in such action.

Section 8.3 Continuity of Service and Performance. Unless otherwise agreed in writing, the Parties shall continue to provide service and honor all other commitments under this Agreement, any Shared Contract and each Ancillary Agreement during a Dispute with respect to all matters not subject to such Dispute.

ARTICLE IX

INSURANCE MATTERS

Section 9.1 Rights to Alkermes Policies.

(a) Mural acknowledges and agrees that, from and after the Distribution Effective Time, except as expressly provided in this Agreement or any Ancillary Agreement, neither Mural nor any member of the Mural Group shall have any rights to or under any Policies of Alkermes, other than any insurance Policies acquired prior to the Distribution Effective Time, including any renewal or tail period thereof, directly by and in the name of Mural or a member of the Mural Group or as expressly provided in Section 6.5 or this Article IX. For the avoidance of doubt, Mural acknowledges and agrees that the Mural Group and not any member of the Alkermes Group shall be responsible for establishing any and all insurance programs covering the Mural Group for its activities after the Distribution Effective Time as may be required to comply with the Mural Group’s contractual obligations and such other insurance Policies required by Law or as necessary or appropriate to operate the Oncology Business, including with respect to general liability, product liability, workers’ compensation, directors’ and officers’ liability and fiduciary liability.

(b) The Parties acknowledge that, as of the Distribution Date, Alkermes’ director and officer liability insurance policies will continue to provide insurance coverage for directors and officers of Mural who served as directors or officers of Alkermes or any of its Subsidiaries prior to the Distribution Effective Time, but such coverage shall only extend to acts occurring prior to the Distribution Effective Time that would have been covered by Alkermes’ director and officer liability insurance policy if such individual remained a director or officer of Alkermes. Such coverage shall also extend to employees with respect to securities law claims only. Alkermes agrees not to terminate or amend this coverage in a manner materially adverse to these individuals.

(c) This Agreement shall not be considered as an attempted assignment of any insurance Policy or as a contract of insurance and shall not be construed to waive any right or remedy of any member of the Alkermes Group in respect of any of the Alkermes insurance Policies and programs or any other contract or policy of insurance. Except as set forth in Section 9.1(b), the Alkermes Group may, at any time, without liability or obligation to any member of the Mural Group, amend, commute, terminate, buy-out, extinguish liability under or otherwise modify any insurance Policies (and claims of the Mural Group pursuant to this Article IX shall be subject to any such amendments, commutations, terminations, buy-outs, extinguishments and modifications).

(d) No member of the Alkermes Group shall have any obligation to secure extended reporting for any claims under any of the Alkermes Group’s claims-made or occurrence-reported liability policies for any acts or omissions by any member of the Mural Group occurring prior to the Distribution Effective Time.

56

Section 9.2 Claims. Nothing in this Article IX will be construed to limit or otherwise alter in any way the indemnity obligations of the Parties, including (i) with respect to the Mural Group, Mural Liabilities, (ii) with respect to the Alkermes Group, Alkermes Retained Liabilities and (iii) those created by this Agreement, by operation of law or otherwise. The Parties acknowledge that Alkermes has used its commercially reasonable efforts to structure its director and officer insurance Policies consistent with such indemnity obligations.

ARTICLE X

MISCELLANEOUS

Section 10.7 Waivers. The delay or failure of either Party to exercise or enforce any of its rights under this Agreement will not constitute, or be deemed to be, a waiver of those rights, nor will any single or partial exercise of any such rights preclude any other or further exercise thereof or the exercise of any other right. No waiver of any provision of this Agreement will be effective unless it is in writing and signed by the Party against which it is being enforced.

Section 10.8 Assignment. No Party may assign any rights or delegate any obligations arising under this Agreement, in whole or in part, directly or indirectly, without the prior written consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), and any attempt to so assign any rights or delegate any obligations arising under this Agreement without such consent shall be void. Notwithstanding the foregoing, no such consent shall be required for any such assignment or delegation (i) with respect to Alkermes, to a Subsidiary of Alkermes (so long as such Subsidiary remains a Subsidiary of Alkermes), (ii) with respect to Mural, to a Subsidiary of Mural (so long as such Subsidiary remains a Subsidiary of Mural) or (iii) to a bona fide Third Party in connection with a merger, reorganization, consolidation or the sale of all or substantially all the assets of a Party so long as the resulting, surviving or transferee entity assumes all the obligations of the assigning Party by operation of Law or pursuant to an agreement in form and substance reasonably satisfactory to the non-assigning Party; provided, however, that in the case of each of the preceding clauses (i) and (ii), no assignment permitted by this Section 10.8 shall release the assigning Party from liability for the full performance of its obligations under this Agreement.

Section 10.9 Successors and Assigns. The provisions of this Agreement and the obligations and rights hereunder shall be binding upon, inure to the benefit of and be enforceable by (and against) the Parties and their respective successors (whether by merger, acquisition of assets or otherwise) and permitted assigns.

Section 10.10 Termination and Amendment. This Agreement (including Article VI hereof) may be terminated, modified or amended, and the Distribution may be amended, modified or abandoned, at any time prior to the Distribution Effective Time by and in the sole and absolute discretion of Alkermes without the approval of Mural or the shareholders of Alkermes. In the event of such termination, no Party shall have any liability of any kind to the other Party or any other Person by reason of such termination. After the Distribution Effective Time, this Agreement may not be terminated, modified or amended except by an agreement in writing signed by Alkermes and Mural.

Section 10.11 Payment Terms.

(a) Except as set forth in Article VI or as otherwise expressly provided to the contrary in this Agreement or in any Ancillary Agreement, any amount to be paid or reimbursed by a Party (and/or a member of such Party’s Group) to the other Party (and/or a member of such other Party’s Group) under this Agreement shall be paid or reimbursed hereunder within sixty (60) days after presentation of an invoice or a written demand therefor, in either case setting forth, or accompanied by, reasonable documentation or other reasonable explanation supporting such amount.

60

(b) Except as set forth in Article VI or as expressly provided to the contrary in this Agreement or in any Ancillary Agreement, any amount not paid when due pursuant to this Agreement (and any amount billed or otherwise invoiced or demanded and properly payable that is not paid within sixty (60) days of such bill, invoice or other demand) shall bear interest at a rate per annum equal to the Prime Rate, from time to time in effect, plus two percent (2%), calculated for the actual number of days elapsed, accrued from the date on which such payment was due up to the date of the actual receipt of payment.

(c) Without the consent of the Party receiving any payment under this Agreement specifying otherwise, all payments to be made by either Alkermes or Mural under this Agreement shall be made in U.S. dollars. Except as expressly provided herein, any amount which is not expressed in U.S. dollars shall be converted into U.S. dollars by using the exchange rate published on Bloomberg at 5:00 p.m., Eastern time, on the day before the relevant date, or in The Wall Street Journal, Eastern Edition, on such date if not so published on Bloomberg. Except as expressly provided herein, in the event that any indemnification payment required to be made hereunder or under any Ancillary Agreement may be denominated in a currency other than U.S. dollars, the amount of such payment shall be converted into U.S. dollars on the date notice of the claim is given to the Indemnifying Party.

Section 10.12 Subsidiaries. Each of the Parties shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party or by any entity that becomes a Subsidiary of such Party at or after the Distribution Effective Time, in each case to the extent such Subsidiary remains a Subsidiary of the applicable Party.

Section 10.13 Third Party Beneficiaries. Except (i) as provided in Article VI relating to Indemnitees and for the releases under Section 6.1 of any Person as provided therein and (ii) as specifically provided in Section 7.9 hereof or in any Ancillary Agreement, this Agreement is solely for the benefit of the Parties and shall not be deemed to confer upon any Person other than the Parties any remedy, claim, liability, reimbursement, cause of Action or other right beyond any that exist without reference to this Agreement.

Section 10.14 Titles and Headings. Titles and headings to sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

Section 10.15 Schedules.

(a) The Schedules shall be construed with and as an integral part of this Agreement to the same extent as if the same had been set forth verbatim herein.

(b) Subject to the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), each Party shall be entitled to update the Schedules from and after the date hereof until the Distribution Effective Time.

61

Section 10.16 Governing Law. This Agreement will be governed by, construed and interpreted in accordance with the Laws of the State of Delaware, without reference to principles of conflicts of Laws. Subject to Section 8.2, each Party irrevocably consents to the exclusive jurisdiction, forum and venue of the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, any Delaware State court or the federal court sitting in the State of Delaware) over any and all claims, disputes, controversies or disagreements between the Parties under or related to this Agreement or any of the transactions contemplated hereby, including their execution, performance or enforcement, whether in contract, tort or otherwise. Each of the Parties hereby agrees that it shall not assert, and shall hereby waive, any claim or right or defense that it is not subject to the jurisdiction of such courts, that the venue is improper, that the forum is inconvenient or any similar objection, claim or argument.

Section 10.17 Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The Parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 10.18 Public Announcements. From and after the Distribution Effective Time, Alkermes and Mural shall consult with each other before issuing, and each shall give the other the opportunity to review and comment upon, that portion of any press release or other public statement, including a statement made to its investors, that relates to the transactions contemplated by this Agreement or the Ancillary Agreements, and shall not issue any such press release or make any such public statement prior to such consultation, except (a) as may be required by applicable Law, court process or obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system; (b) for disclosures made that are substantially identical to disclosure contained in any Distribution Disclosure Document or any prior written public statement not made in violation of this Section 10.18; or (c) with respect to a Party, for disclosure concerning the ordinary course operation of such Party’s business (other than any Dispute), notwithstanding that the disclosure may relate to arrangements under the Transition Services Agreements (including the exhibits and schedules thereto).

Section 10.19 Interpretation. The Parties have participated jointly in the negotiation and drafting of this Agreement. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the Party drafting or causing any instrument to be drafted.

Section 10.20 No Duplication; No Double Recovery. Nothing in this Agreement or any Ancillary Agreement is intended to confer to or impose upon any Party a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances (including with respect to the rights, entitlements, obligations and recoveries that may arise out of one or more of Section 6.2, Section 6.3, Section 6.4, Section 6.5 and Section 6.6).

62

Section 10.21 No Admission of Liability. The allocation of Assets and Liabilities herein (including on the Schedules hereto) is solely for the purpose of allocating such Assets and Liabilities between Alkermes and Mural and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à-vis any Third Party.
