 (a) Seller agrees that Purchaser is entitled to the Purchased
Assets and may enforce such entitlement directly against Counterparty pursuant to the License Agreement and, notwithstanding any claim or Set-off that Seller may have against Purchaser or that Counterparty may have against Seller, Seller agrees and
will use its best efforts to ensure (including taking such actions as Purchaser shall reasonably request) that Counterparty remits all payments that Counterparty is required to pay to Seller under the License Agreement with respect to the Purchased
Assets directly to Purchaser (and/or to a Permitted Assignee of Purchaser), pursuant to the Counterparty Instruction. 
 (b)
For the avoidance of doubt, the parties hereto understand and agree that if Counterparty fails to pay any Royalties when Seller or Purchaser reasonably believes such Royalties are due under the License Agreement, except for any Set-off contemplated
by Section 2.2(c) (each such unpaid amount, a “Discrepancy”), and if such Discrepancy is not the result of a default or breach by Seller under the License Agreement, then Seller shall not be obligated to pay to Purchaser or
otherwise compensate or make Purchaser whole with respect to any such Discrepancy so long as Seller is in compliance with the provisions of this Agreement; provided, however, that nothing in this Section 2.2(b) shall limit or
affect in any respect the rights of any Purchaser Indemnified Party under Article VII. 
 (c) Seller agrees that it will
promptly (and in any event within three Business Days) pay to Purchaser in accordance with Section 5.4 the amount of any Set-off by Counterparty against any Royalties or other Purchased Assets to the extent that such Set-off arises out of or
relates to any period prior to the Royalties Commencement Date or to any events occurring, circumstances existing or actions taken prior to the Royalties Commencement Date. 
 Section 2.3 Purchase Price. In full consideration for the sale, assignment, transfer and conveyance of the Purchased Assets, and subject to the
terms and conditions set forth herein, Purchaser shall pay to Seller, or Seller’s designee, on the Closing Date, the sum of $91,319,781.37, by wire transfer to an account designated in writing by Seller at least two Business Days prior to the

Purchased Assets, shall be deemed a capital contribution by Seller to Purchaser in an amount equal to such excess portion. 
 Section 2.4
No Assumed Obligations. Notwithstanding any provision in this Agreement or any other writing to the contrary, Purchaser is purchasing, acquiring and accepting only the Purchased Assets and is not assuming any liability or obligation of Seller
or any of Seller’s Affiliates of whatever nature, whether presently in existence or arising or asserted hereafter, whether under any License Documentation (including any obligation to pay any amounts to, or accept any Set-off by, Counterparty
or any of Counterparty’s Affiliates), any Transaction Document or otherwise. All such liabilities and obligations shall be retained by and remain obligations and liabilities of Seller or Seller’s Affiliates (the “Excluded

Assets free and clear of all Liens, including following the Closing. 
 (b) Seller and Purchaser shall cooperate and provide
assistance as reasonably requested by the other party hereto, at the expense of such other party hereto (except as otherwise provided herein), in connection with any litigation, arbitration or other proceeding (whether threatened, existing,
initiated or contemplated prior to, on or after the date hereof) to which the other party hereto, any of its Affiliates or controlling Persons or any of their respective officers, directors, shareholders, members, controlling Persons, managers,

 (e) If Counterparty takes any Set-off in accordance with the terms of the License
Agreement where such Set-off (or any portion thereof) is made in respect of any event occurring, circumstance existing or action taken prior to the Royalties Commencement Date but has the effect of reducing amounts to be paid to Purchaser following
the Closing Date, then Seller shall cause the amount of such Set-off (or portion thereof, as the case may be) to be paid promptly (but in no event later than three Business Days following such Set-off) to the Purchaser Account. 
 Section 5.5 License Documentation. 
 (a) Seller shall fully and timely comply with its obligations under the License Documentation and, without the prior written consent of Purchaser, shall not (i) forgive, release or compromise any amount owed to
or becoming owing to Seller under the License Documentation, (ii) waive, amend, cancel, terminate or fail to exercise any rights constituting or involving the right to receive the Royalties, (iii) create or permit to exist any Lien on the
License Documentation, Purchased Assets or the Indevus Intellectual Property, (iv) grant any license, sublicense or other right under the Indevus Intellectual Property, except for licenses granted by Seller to Counterparty under the License

 (b) Promptly after (i) receiving notice from Counterparty, Madaus, Supernus or any other Person (A) terminating any of the
License Documentation (in whole or in part), (B) alleging any breach of or default under any of the License Documentation by Seller or (C) asserting the existence of any facts, circumstances or events that, alone or together with other
facts, circumstances or events, could reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach of or default under any of the License Documentation or the right to terminate any of the
License Documentation (in whole or in part) by Counterparty, Madaus, Supernus or any other Person or (ii) Seller otherwise has knowledge of any fact, circumstance or event that, alone or together with other facts, circumstances or events, could
reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach of or default under any of the License Documentation by Seller or give the right to terminate any of the License Documentation (in
whole or in part) by Counterparty, Madaus, Supernus or any other Person, in each case, Seller shall (A) promptly give a written notice to Purchaser describing in reasonable detail the relevant breach, default or termination event, including a
copy of any written notice received from Counterparty, Madaus, Supernus or the other relevant Person, and, in the case of any breach or default or alleged breach or default by Seller, describing in reasonable detail any corrective action Seller
proposes to take, and (B) use its best efforts to promptly cure such breach or default and shall give written notice to Purchaser upon curing such breach or default; provided, however, that, if Seller fails to promptly cure such
breach or default promptly, Purchaser shall be entitled to take any and all actions Purchaser considers reasonably necessary to promptly cure such breach or default, and Seller shall promptly reimburse Purchaser for all costs and expenses incurred
in connection therewith. 
  

 24 








 (c) Promptly after Seller obtains knowledge of a breach or default or alleged breach or
default under any of the License Documentation by Counterparty or any other Person (each, a “Defaulting Party”) or of the existence of any facts, circumstances or events that, alone or together with other facts, circumstances or
events, could reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach or default under any of the License Documentation by a Defaulting Party or the right to terminate any of the License
Documentation (in whole or in part) by Seller, in each case, Seller shall (i) promptly give a written notice to Purchaser describing in reasonable detail the relevant breach, default or termination event and (ii) as and when requested in
writing by Purchaser, proceed in consultation with Purchaser and take such permissible actions (including commencing legal action against the Defaulting Party) as Purchaser may in writing instruct with respect to such breach, default or termination
event or alleged breach, default or termination event (including the selection of legal counsel reasonably satisfactory to Purchaser) to enforce compliance by the Defaulting Party with the relevant provisions of the License Documentation and to
exercise any or all of Seller’s rights and remedies, whether under the License Documentation or by operation of law, with respect thereto. Purchaser shall have the right, at its sole expense, to participate in and control, with counsel
appointed by it, any meeting, discussion, action, suit or other proceeding relating to any such breach, default or termination event or alleged breach, default or termination event, including any counterclaim, settlement discussions or meetings;
provided, that the fees and expenses of Purchaser’s counsel in connection therewith shall be borne by Seller if such breach, default or termination event or alleged breach, default or termination event results from, or is caused by,
directly or indirectly, a breach or default by Seller. 
 (d) Seller shall (i) subject to the provisions of the License
Documentation and any rights of Counterparty thereunder, take any and all actions, and prepare, execute, deliver and file any and all agreements, documents and instruments, that are reasonably necessary or desirable to diligently maintain the
Indevus Intellectual Property, at the sole expense of Seller (which expenses may be reimbursable to Seller by Counterparty under the License Agreement), and (ii) diligently defend (and enforce) the Indevus Intellectual Property against
infringement or interference by any other Person, and against any claims of invalidity or unenforceability, in any jurisdiction (including by bringing any legal action for infringement or defending any counterclaim of invalidity or action of a third
party for declaratory judgment of non-infringement or non-interference), with counsel reasonably satisfactory to Purchaser and whose reasonable fees and expenses shall be borne by Seller. Seller shall not disclaim or abandon, or fail to take any
action necessary or desirable to prevent the disclaimer or abandonment of, the applicable Indevus Intellectual Property. Purchaser shall have the right, at its sole expense, to participate in and control, with counsel appointed by it, any meeting,
discussion, action, suit or proceeding involving the infringement, legality, validity or enforceability of the Indevus Intellectual Property or the License Agreement to the same extent that Seller has such rights under the License Agreement,
including any counterclaim, settlement discussions or meetings, and Seller shall exercise and enforce such rights on its own behalf (and on behalf of Purchaser) to the fullest extent under the terms of the License Agreement; provided, that
Seller’s exercise and 

  

 25 








 
enforcement of such rights shall not result in a breach of this Agreement or a Material Adverse Effect; provided, further, that the fees and
expenses of Purchaser’s counsel in connection therewith shall be borne by Seller if such infringement, legality, validity or enforceability results from, or is caused by, directly or indirectly, Seller. 
 (e) Except in connection with an assignment by Seller to any other Person with which Seller may merge or consolidate or to which Seller
may sell all or substantially all of its assets or all of its assets related to the Licensed Products in accordance with the provisions of Section 8.4, Seller shall not dispose of or encumber the Indevus Intellectual Property (in whole or in
part). 
 (f) Seller shall make available its records and personnel to Purchaser in connection with any prosecution of
litigation by Purchaser against any party to any of the License Documentation to enforce any of Purchaser’s rights under any such License Documentation, and provide reasonable assistance and authority to file and bring the litigation,
including, if required to bring the litigation, being joined as a party plaintiff. 
 (g) If Madaus or Supernus becomes
insolvent and seeks to reorganize under Chapter 11 of Title 11 of the United States Code (or equivalent provisions of foreign law), Seller shall elect, as licensee under the Madaus Agreements or the Supernus Agreement, as the case may be, to retain
its rights under such Madaus Agreements or Supernus Agreement, as the case may be, pursuant to Section 365(n) of Title 11 of the United States Code (or any equivalent provisions of foreign law) by written request as soon as practicable
thereafter. 
 Section 5.6 Termination of License Agreement. 
 (a) Without limiting the provisions of Section 5.5, if Counterparty or Seller terminates or provides written notice of termination of
the License Agreement (in whole or in part), or the License Agreement is otherwise terminated (in whole or in part), then Seller shall provide assistance to and cooperate with Purchaser, at Purchaser’s sole discretion, cost and expense
(including Purchaser’s payment of Seller’s reasonable attorneys’ fees in connection therewith, if any), in such efforts as Purchaser shall undertake in connection with the negotiation of a license of the Indevus Intellectual Property,
which shall include terms no less favorable to Seller than those contained in the License Agreement with respect to obligations and costs imposed on Seller, disclaimers of Seller’s liability, intellectual property ownership and control,
commercialization diligence and indemnification of Seller (any such license, a “New Arrangement”). Should Purchaser identify any New Arrangement, Seller agrees to duly execute and deliver such New Arrangement that satisfies the
foregoing requirements promptly upon the written request of Purchaser. In the event Seller enters into a New Arrangement, Seller agrees to comply with the provisions of this Agreement in connection with the New Arrangement and references herein to
the Purchased Assets and the License Agreement shall be deemed to be references to any new purchased asset and any new license agreement constructed under the New Arrangement, and references to Counterparty shall be deemed to be references to the
other party to such new license agreement and that other party’s Affiliates and sublicensees. 
  

 26 








 (b) If there occurs a merger or consolidation of Seller, on the one hand, and
Counterparty or its Affiliates, on the other hand, a sale of all or substantially all of Seller’s assets to Counterparty or a sale or assignment of the License Agreement or the Indevus Intellectual Property by Seller to Counterparty, and in any
such case the License Agreement is terminated in connection therewith, Seller (or its successor) shall pay Purchaser royalties on the Net Sales of Products for the term of the License Agreement on the same basis as if the License Agreement had
continued and Purchaser’s rights with respect to the Purchased Assets and the covenants of Seller under this Agreement shall continue to apply on the same basis as if the License Agreement was in place between Seller and Counterparty.

 Section 5.7 Audits. Seller shall not, without the prior written consent of Purchaser, and Seller shall, upon the written request of
Purchaser, cause an inspection or audit of Counterparty’s books and records to be conducted pursuant to, and in accordance with, Section 6.5 of the License Agreement; provided, however, that Seller shall retain the exclusive
right to inspect and audit Counterparty’s books and records at any time and from time to time at its sole discretion for payments that are paid or payable to Seller pursuant to the License Agreement with respect to Net Sales and Royalties
attributable to the period prior to the Royalties Commencement Date. For the purposes of exercising Purchaser’s rights pursuant to this Section 5.7, Seller shall select such public accounting firm as Purchaser shall recommend for such
purpose. Seller and Purchaser agree that all of the expenses of any inspection or audit carried out for the benefit of Purchaser that would otherwise be borne by Seller pursuant to the License Agreement shall instead be borne by Purchaser, including
such fees and expenses of such public accounting firm as are to be borne by Seller pursuant to Section 6.5 of the License Agreement together with Seller’s reasonable out-of-pocket costs incurred in connection with such examination or
audit. Seller will furnish any inspection or audit report prepared by such public accounting firm to Purchaser, provided, however, that Seller shall not furnish such inspection or audit report prior to such time that Counterparty has
made a filing with the Securities and Exchange Commission including financial statements relating to the full period covered by such inspection or audit report. Purchaser shall have the right to require Seller, in writing, at the sole expense of
Purchaser, to exercise Seller’s rights under the License Agreement to cause Counterparty to cure such discrepancy in accordance with the License Agreement. 
 Section 5.8 Tax Matters. All payments to Purchaser under this Agreement shall be made without any deduction or withholding for or on account of any tax; provided, that, if deduction or withholding of any
tax is required from any such payment under this Agreement or from any payment under the License Agreement by reason of Seller’s being a party to the License Agreement, then the sum payable shall be increased and paid by Seller as necessary so
that, after making all required deductions and withholdings, Purchaser receives an amount equal to the amount that it would have received had no such deductions or withholdings been made. 
 Section 5.9 Third Party Payments. Seller shall cause all amounts received by Seller in respect of clauses (a)(i) through (a)(iv) of the definition
of “Royalties” that relate to amounts payable by Seller to other Persons (including Supernus or Madaus) to be received and held in one or more separate accounts in trust or escrow for such Persons and not commingled with any other funds of
Seller, and Seller shall cause such funds to be paid to such Persons in accordance with Seller’s obligations to such Persons. 
  

 27 








 Section 5.10 Existence. Seller shall (i) preserve and maintain its existence,
(ii) preserve and maintain its rights, franchises and privileges unless failure to do any of the foregoing would not have or would not be reasonably likely to have a Material Adverse Effect and (iii) qualify and remain qualified in good
standing in each jurisdiction where the failure to preserve and maintain such existence, rights, franchises, privileges and qualifications would be reasonably likely to have such a Material Adverse Effect, including appointing and employing such
agents or attorneys in each jurisdiction where it shall be necessary to take action under this Agreement. 
 Section 5.11 Other
Covenants. So long as Seller maintains an equity ownership interest in Purchaser, Seller shall: 
 (a) file all tax
returns and reports required by law to be filed by it and pay all taxes required to be paid by it, except any such taxes that are being diligently contested in good faith by appropriate proceedings and for which adequate reserves in accordance with
GAAP have been set aside on its books, and it shall not file any tax return or report under any name other than its exact legal name; 
 (b) not, and shall not permit Purchaser to, make any election under Treasury Regulations Section 301.7701-3(c) (or any successor provision) to classify Purchaser as an association taxed as a corporation;

 (c) treat any indebtedness issued by Purchaser as debt for U.S. federal income tax purposes; 
 (d) maintain in place all policies and procedures, and take and continue to take all actions, described in the assumptions as to facts
relating to the separateness of Purchaser and Seller set forth in, and forming the basis of, the opinions delivered pursuant to Section 6.3 of the Note Purchase Agreements, and comply with, and cause Purchaser to comply with, the provisions of
Section 5.2(o) of the Indenture (as to Purchaser); 
 (e) cause Purchaser to perform its obligations under the agreements
(including any Transaction Documents) to which Purchaser is a party; 
 (f) not take any action to waive, repeal, amend, vary,
supplement or otherwise modify the organizational documents of Purchaser in a manner that would adversely affect the rights, privileges or preferences of any holder of any indebtedness of Purchaser; 
 (g) not take any action or cause or permit Purchaser (except as required by law) to take any action to cause Purchaser to become subject
to any insolvency or similar proceeding; 
 (h) not institute against Purchaser, or join any Person in instituting against
Purchaser, any insolvency or similar proceeding until one year and one day after the date on which any indebtedness of Purchaser has been paid in full; 
  

 28 








 (i) not cause Purchaser to petition for bankruptcy before one year and one day have
elapsed since the final payments to any holder of any indebtedness of Purchaser or, if longer, the applicable preference period then in effect; 
 (j) not take any action to dissolve Purchaser; 
 (k) not pass a resolution to cause Purchaser
to be liquidated before one year and two days have elapsed since any indebtedness of Purchaser has been paid in full; and 
 (l) during any period in which Seller is not subject to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, deliver to Purchaser (i) audited financial statements of Seller with respect to its most recent fiscal
year no later than 90 days after the end of such fiscal year and (ii) unaudited interim financial statements of Seller with respect to each fiscal quarter (except for fiscal year-end) no later than 45 days after the end of such fiscal quarter,
in each case, prepared in accordance with GAAP in all material respects.

 ARTICLE VII 
 INDEMNIFICATION 
 Section 7.1 Indemnification by Seller. Seller hereby indemnifies and holds
each of Purchaser and its Affiliates and any and all of their respective partners, directors, managers, members, officers, employees, agents and controlling Persons (each, a “Purchaser Indemnified Party”) harmless from and against,
and will pay to each Purchaser Indemnified Party the amount of, any and all Losses incurred or suffered by such Purchaser Indemnified Party, whether or not involving a third party claim, demand, action or proceeding, arising out of (i) any
breach of any representation, warranty or certification made by Seller in any of the Transaction Documents or certificates given by Seller in writing pursuant hereto or thereto, (ii) any breach of or default under any covenant or agreement by
Seller pursuant to any Transaction Document or the License Documentation, (iii) any Excluded Liabilities and Obligations and (iv) any fees, expenses, costs, liabilities or other amounts incurred or owed by Seller to any brokers, financial
advisors or comparable other Persons retained or employed by it in connection with the transactions contemplated by this Agreement. Any amounts due to any Purchaser Indemnified Party hereunder shall be payable by Seller to such Purchaser Indemnified
Party promptly upon demand. 
 Section 7.2 Indemnification by Purchaser. Purchaser hereby indemnifies and holds each of Seller and its
Affiliates and any and all of their respective partners, directors, managers, members, officers, employees and agents (each, a “Seller Indemnified Party”) harmless from and against, and will pay to each Seller Indemnified Party the
amount of, any and all Losses incurred or suffered by such Seller Indemnified Party, whether or not involving a third party claim, demand, action or proceeding, arising out of any breach of or default under any covenant or agreement by Purchaser in
favor of Seller pursuant to any Transaction Document; provided, however, that this Section 7.2 shall apply only if, at the time of such breach or default, Purchaser is not “controlled” (as such term is defined in the
definition of “Affiliate”) by Seller or any of Seller’s Affiliates. Any amounts due to any Seller Indemnified Party hereunder shall be payable by Purchaser to such Seller Indemnified Party upon demand. 
 Section 7.3 Procedures. If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or
alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to Section 7.1 or Section 7.2, the indemnified party shall, promptly after receipt of notice of the commencement of
any such claim, demand, action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers served, if any; provided, that the omission to so notify
such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under Section 7.1 or Section 7.2 unless, and only to the extent that, such omission results in the forfeiture of,
or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such action is brought against an indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled, at the indemnifying party’s sole cost and expense, to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably 
  

 30 








 
satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after
notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Article VII for any legal or other expenses subsequently
incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own counsel, but the reasonable fees and expenses
of such counsel shall be at the expense of such indemnified party unless (a) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (b) the indemnifying party has assumed the defense
of such proceeding and has failed within a reasonable time to retain counsel reasonably satisfactory to such indemnified party or (c) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party
and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of counsel to the indemnifying party. It is agreed that the
indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all
such indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or
discharge of any claim or pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement, compromise or
discharge, as the case may be, (i) includes an unconditional written release of such indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such
claim or proceeding, (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party and (iii) does not impose any continuing material obligation or restrictions on
any indemnified party. 
 Section 7.4 Exclusive Remedy. Except in the case of fraud or intentional breach, following the Closing, the
indemnification afforded by this Article VII shall be the sole and exclusive remedy for any and all Losses sustained or incurred by a party hereto in connection with the transactions contemplated by the Transaction Documents, including with respect
to any breach of any representation, warranty or certification made by a party hereto in any of the Transaction Documents or certificates given by a party hereto in writing pursuant hereto or thereto or any breach of or default under any covenant or
agreement by a party hereto pursuant to any Transaction Document. Notwithstanding anything in this Agreement to the contrary, in the event of any breach or failure in performance of any covenant or agreement contained in any Transaction Document,
the non-breaching party shall be entitled to specific performance, injunctive or other equitable relief pursuant to Section 8.2. 
  

 31 








 ARTICLE VIII 
 MISCELLANEOUS 
 Section 8.1 Survival. All representations, warranties and covenants made
herein and in any other Transaction Document or any certificates delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the Closing. The rights hereunder to indemnification, payment of Losses or other
remedies based on such representations, warranties and covenants shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time (whether before or after the execution and
delivery of this Agreement or the Closing) in respect of the accuracy or inaccuracy of or compliance with, any such representation, warranty or covenant. The waiver of any condition based on the accuracy of any representation or warranty, or on the
performance of or compliance with any covenant, shall not affect the rights hereunder to indemnification, payment of Losses or other remedies based on such representations, warranties and covenants. 
 Section 8.2 Specific Performance. Each of the parties hereto acknowledges that the other party hereto will have no adequate remedy at law if it
fails to perform any of its obligations under any of the Transaction Documents. In such event, each of the parties hereto agrees that the other party hereto shall have the right, in addition to any other rights it may have (whether at law or in
equity), to specific performance of this Agreement.

their respective successors and permitted assigns. Seller shall not be entitled to assign any of its obligations and rights under any of the Transaction Documents or the License Documentation without the prior written consent of Purchaser;
provided, however, that Seller may, without the consent of Purchaser, assign any of its obligations or rights under the Transaction Documents or the License Documentation to any other Person with which it may merge or consolidate or to
which it may sell all or substantially all of its assets or all of its assets related to the Finished Products, provided that the assignee under such assignment agrees to be bound by the terms of the Transaction Documents or the License
Documentation, as applicable, and furnish a written agreement to Purchaser in form and substance reasonably satisfactory to Purchaser to that effect. Purchaser may assign any of its obligations and rights hereunder without the consent of Seller
subject to the limitations contained in the Allergan Consent. Purchaser shall give notice of any such assignment to Seller after the occurrence thereof. Seller shall be under no obligation to reaffirm any representations, warranties or covenants
made in this Agreement or any of the other Transaction Documents or take any other action in connection with any such assignment by Purchaser. 
 Section 8.5 Independent Nature of Relationship. Except for any equity ownership interest of Purchaser held by Seller, the relationship between Seller and Purchaser is solely that of seller and purchaser, and neither Seller nor
Purchaser has any fiduciary or other special relationship with the other party hereto or any of its Affiliates. Nothing contained herein or in any other Transaction Document shall be deemed to constitute Seller and Purchaser as a partnership, an
