 7.3.2. Royalty Term.  

(a) Salix’s obligations to pay royalties under Section 7.3.1 shall terminate with respect to any Licensed Bioadhesive Product
in each country in the Territory upon the earlier of (a) the date of the first commercial sale (by a Person other than Salix or its Sublicensees or any of its or their respective Affiliates) in such country of a product that is approved by a
Regulatory Authority and constitutes a Prescription Competitive Product in respect of such Licensed Bioadhesive Product and (b) the later of (i) the tenth (10th) anniversary of the First Commercial Sale of such Licensed Bioadhesive
Product and (ii) the first date on which there is no longer (A) a Lupin Patent or Lupin Improvement Patent that includes at least one Valid Claim in the country that would be infringed by Salix’s Exploitation of the Licensed
Bioadhesive Product in such country in the absence of the licenses granted in Sections 2.1 and 8.1.4 or (B) any Data Exclusivity with respect to such Licensed Bioadhesive Product in the country. If, prior to the termination of the royalty
obligations of Salix under Section 7.3.1, this Agreement has not been terminated pursuant to Section 13.2, 13.3, 13.4, or 13.5, then upon termination of the royalty obligations of Salix under Section 7.3.1 with respect to any Licensed
Bioadhesive Product in a particular country that is a Designated Licensed Product, the license grants to Salix in Section 2.1 in respect of such Licensed Bioadhesive Product shall become non-exclusive, fully paid-up, perpetual and irrevocable
with respect to such Licensed Bioadhesive Product in such country. Following any termination of Salix’s obligation to pay royalties under Section 7.3.1 in respect of any Licensed Bioadhesive Product in a particular country, Salix shall
only be responsible for any royalty payments based on Net Sales of such Licensed Bioadhesive Product that occurred in such country prior to the effective date of such termination. 

(b) Salix’s obligations to pay royalties under Section 7.3.1 shall terminate with respect to any Covered Non-Bioadhesive
Product in each country in the Territory upon the earlier of (i) the date of the first commercial sale (by a Person other than Salix or its Sublicensees or any of its or their respective Affiliates) in such country of a product that is approved
by a Regulatory Authority and constitutes a Prescription Competitive Product in respect of such Covered Non-Bioadhesive Product and (ii) the first date on which the Covered Non-Bioadhesive Product ceases to constitute a Covered Product. For the
avoidance of doubt, (i) if, prior to the termination of the royalty obligations of Salix under Section 7.3.1, this Agreement has not been terminated pursuant to Section 13.2, 13.3, 13.4, or 13.5, upon termination of the royalty
obligations of Salix under Section 7.3.1 with respect to any Covered Non-Bioadhesive Product in a particular country that is a Designated Licensed Product, the license grants to Salix in Section 2.1 in respect of such Covered
Non-Bioadhesive Product shall, to the extent still relevant, become non-exclusive, fully paid-up, perpetual and irrevocable with respect to such Covered Non-Bioadhesive Product in such country; and (ii) following any termination of Salix’s
obligation to pay royalties under Section 7.3.1 in respect of any Covered Non-Bioadhesive Product in a particular country, Salix shall only be responsible for any royalty payments based on Net Sales of the Covered Non-Bioadhesive Product that
occurred in such country prior to the effective date of such termination.

 7.3.3. Royalty Step-Down. 

(a) The royalties payable pursuant to Section 7.3.1 in respect of any Licensed Bioadhesive Product in a particular country shall be
reduced by [*] ([*]) (a) during any period in which there are no Valid Claims of any Lupin Patent or Lupin Improvement Patent that would be infringed by the Exploitation of such Licensed Bioadhesive Product in such country in the absence of the
license grants under Sections 2.1 and 8.1.4 or (b) if, following the first commercial sale (by a Person other than Salix or its Sublicensees or any of its or their respective Affiliates) in such country of a Non-Prescription Competitive
Bioadhesive Product, (i) aggregate commercial sales of units of such Licensed Bioadhesive Product in such country decline on a Calendar Quarter-by-Calendar Quarter basis, based on data generated by, as Salix may determine, Wolters Kluwer or IMS
International (or if such data is not available from either of such sources, another reliable data source that is mutually agreed by the Parties by mutual written consent), for [*] ([*]) or more consecutive Calendar Quarters during the first [*]
([*]) years following such first commercial sale in such country of a Non-Prescription Competitive Bioadhesive Product and (ii) such decline in commercial sales of units of such Licensed Bioadhesive Product in such country over [*] ([*])
consecutive Calendar Quarters in the aggregate is at least [*] percent ([*]%). 
 (b) The royalties payable pursuant to
Section 7.3.1 in respect of any Covered Non-Bioadhesive Product in a particular country shall be reduced by [*] ([*]) if, following the first commercial sale (by a Person other than Salix or its Sublicensees or any of its or their respective
Affiliates) in such country of a product that constitutes a Non-Prescription Competitive Product in respect of such Covered Non-Bioadhesive Product, (i) aggregate commercial sales of units of such Covered Non-Bioadhesive Product in such country
decline on a Calendar Quarter-by-Calendar Quarter basis, based on data generated by, as Salix may determine, Wolters Kluwer or IMS International (or if such data is not available from either of such sources, another reliable data source that is
mutually agreed by the Parties by mutual written consent), for [*] ([*]) or more consecutive Calendar Quarters during the first [*] ([*]) years following such first commercial sale in such country of such Non-Prescription Competitive Product and
(ii) such decline in commercial sales of units of such Covered Non-Bioadhesive Product in such country over [*] ([*]) consecutive Calendar Quarters in the aggregate is at least [*] percent ([*]%). 

7.3.4. Royalty Payments. Running royalties shall be payable on a quarterly basis, within thirty (30) days after the end of
each Calendar Quarter, based upon the aggregate Net Sales in the Field in the Territory during such Calendar Quarter. Notwithstanding the foregoing, (a) if at the end of a given Calendar Year, the royalty statement described in
Section 7.3.5 shows that Salix has overpaid royalties for any Calendar Quarter during such Calendar Year, then at Salix’s option, (i) Salix shall have the right to deduct the amount of such overpayment from its royalty payment
otherwise due to Lupin for the fourth Calendar Quarter of such Calendar Year, or (ii) Lupin shall reimburse to Salix the amount of such overpayment within thirty (30) days after receipt of the royalty payment or royalty statement for the
fourth Calendar Quarter of such Calendar Year, and (b) if at the end of a Calendar Year, the royalty statement described in Section 7.3.5 shows that Salix has underpaid royalties for any Calendar

 - 33 -

 
Quarter during such Calendar Year, then Salix shall pay to Lupin the amount of such underpayment together with its royalty payment for the fourth Calendar Quarter of such Calendar Year. Royalties
shall be calculated in accordance with GAAP and with the terms of this Article 7. Only one royalty payment shall be due on Net Sales even though the sale or use of the Covered Product may be covered by more than one Patent or item of Lupin
Know-How. 
 7.3.5. Royalty Statements. Each royalty payment hereunder shall be accompanied by a statement in sufficient
detail to allow for the calculation of royalties due hereunder, including by showing at a minimum, for the applicable Calendar Quarter and, in respect of the royalty statement for the fourth Calendar Quarter of each Calendar Year, the Calendar Year:
(a) Invoiced Sales and Net Sales for the relevant period, (b) the number of units of Covered Product sold during the relevant period, (c) a detailed breakdown of any deductions from the Invoiced Sales to obtain Net Sales, (d) the
amount of royalties due on such Net Sales, and (e) the information set forth under clauses (a) through (d) of this Section 7.3.5, disaggregated by Sublicensee.

 (a) Within thirty (30) days following the
end of each of the first three (3) Contract Quarters of each Contract Year, Salix shall pay to Lupin the amount, if any, by which the Creditable Consideration for such Contract Quarter is less than [*] Dollars ($[*]), such [*] Dollar ($[*])
amount to be prorated for any Contract Quarter that is less than a full three (3)-month period based on the number of days in such Contract Quarter divided by ninety (90) (any such amount required to be paid by Salix pursuant to this
Section 7.4, a “Minimum Consideration Quarterly Reconciliation Payment”). 
 (b) Salix shall be entitled
to withhold all or an appropriate portion of any Minimum Consideration Quarterly Reconciliation Payment for a Contract Quarter in the event that Salix should make a good faith determination that the sum of all Creditable Consideration for the
Contract Year in which the Contract Quarter to which the Minimum Consideration Quarterly Reconciliation Payment relates falls plus all Minimum Consideration Quarterly Reconciliation Payments made in respect of Contract Quarters falling in such
Contract Year has or is likely to exceed [*] Dollars ($[*]), such withheld amount to be only such amount as Salix in good faith determines to be appropriate in order to cause the sum of all Creditable Consideration for the Contract Year in which the
Contract Quarter to which the Minimum Consideration Quarterly Reconciliation Payment relates falls plus all Minimum Consideration Quarterly Reconciliation Payments made in respect of Contract Quarters falling in such Contract Year not to exceed [*]
Dollars ($[*]). Prior to effecting any withholding of a Minimum Consideration Quarterly Reconciliation Payment pursuant to the preceding sentence, Salix shall provide Lupin with a written explanation that sets forth, in reasonable detail, the basis
for such withholding and its amount. In the event that Lupin disagrees with any aspect of such explanation, Lupin may at any time notify Salix of its objections. Salix shall consider Lupin’s objections in good faith and make any such
adjustments in prior or future withholdings of Minimum Consideration Quarterly Reconciliation Payments as it may determine as a result of such good faith consideration of Lupin’s objections to be warranted.

 7.4.2. Annual Reconciliation. 

(a) In the event the sum of all Creditable Consideration for a Contract Year plus any Minimum Consideration Quarterly Reconciliation
Payments made in respect of such Contract Year is less than [*] Dollars ($[*]), with such [*] Dollar ($[*]) amount to be prorated for any Contract Year that is less than a full twelve (12)-month period based on the number of days in such Contract
Year divided by three hundred sixty-five (365), then, within thirty (30) days following the end of such Contract Year, Salix shall pay to Lupin an amount equal to the amount of such deficiency (any such amount required to be paid by Salix
pursuant to this Section 7.4.2(a), a “Minimum Consideration Annual Reconciliation Payment”). 
 (b) In
the event the sum of all Creditable Consideration for a Contract Year plus any Minimum Consideration Quarterly Reconciliation Payments made in respect of such Contract Year is more than [*] Dollars ($[*]), with such [*] Dollar ($[*]) amount to be
prorated for any Contract Year that is less than a full twelve (12)-month period based on the number of days in such Contract Year divided by three hundred sixty-five (365), then, Salix may invoice Lupin for a refund of the amount of an excess up to
a maximum of the sum of all Minimum Consideration Quarterly Reconciliation Payments made by Salix in respect of Contract Quarters falling in such Contract Year and Lupin shall pay any such invoice within thirty (30) days of receipt (any such
amount required to be paid by Lupin pursuant to this Section 7.4.2(b), a “Minimum Consideration Annual Reconciliation Refund”). 
 7.5 Mode of Payment. All payments to Lupin under this Agreement shall be made by deposit of Dollars in the requisite amount to such bank account as Lupin may from time to time designate by notice
to Salix. 
 7.6 Taxes. The royalties, milestones and other amounts payable by Salix to Lupin pursuant to this Agreement
(“Payments”) shall not be reduced on account of any taxes unless required by Applicable Law. Lupin alone shall be responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be paid by Salix)
levied on account of, or measured in whole or in part by reference to, any Payments it receives. Salix shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing,
if Lupin is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to Salix or the appropriate governmental authority (with the assistance of Salix to the extent that
this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve Salix of its obligation to withhold tax, and Salix shall apply the reduced rate of
withholding, or dispense with withholding, as the case may be, provided that Salix has received evidence, in a form reasonably satisfactory to Salix, of Lupin’s delivery of all applicable forms (and, if necessary, its receipt of
appropriate 
  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 35 -

 
governmental authorization) at least fifteen (15) days prior to the time that the Payments are due. If, in accordance with the foregoing, Salix withholds any amount, it shall pay to Lupin
the balance when due, make timely payment to the proper taxing authority of the withheld amount and send to Lupin proof of such payment within ten (10) days following such payment. Salix shall be responsible for any sales or other similar tax
that Lupin may be required to collect with respect to the Payments. 
 7.7 Financial Records . Salix shall, and shall
cause its Sublicensees and its and their respective Affiliates to, keep complete and accurate financial books and records pertaining to the Invoiced Sales (including any deductions therefrom) and Net Sales of Covered Product in sufficient detail to
calculate the royalties and other amounts payable under this Agreement. Such books and records shall be retained by Salix, its Sublicensees and its and their Affiliates, until the later of (a) three (3) years after the end of the period to
which such books and records pertain and (b) the expiration of the applicable tax statute of limitations (or any extensions thereof), or for such longer period as may be required by Applicable Law.

 8.4 Infringement
Claims by Third Parties. 
 8.4.1. Defense of Third Party Claims. If a Third Party asserts that a Patent or other
intellectual property right (other than Trademarks, which shall be governed by Section 8.7) owned or controlled by it is infringed by the Exploitation of the Licensed Product, the Party first obtaining knowledge of such a claim shall
immediately provide the other Party notice of such claim along with the related facts in reasonable detail. Salix shall have the first right, but not the obligation, through counsel reasonably acceptable to Lupin, to control the defense of any such
claim in the Territory and Lupin shall have the first right, but not the obligation, through counsel reasonably acceptable to Salix, to control the defense of any such claim outside the Territory. If the Party with primary responsibility for defense
under this Section 8.4.1 does not accept control of the defense of such claim within ninety (90) days (or twenty-five (25) days in the case of an action brought under the Hatch-Waxman Act or within the timeframe of any other relevant
regulatory or statutory framework that may govern) of learning of the claim, or earlier notifies the other Party in writing of its intent not to so assume control of such defense, then the other Party shall have the right, but not the obligation, to
defend against such claim; provided, however, that the non-controlling Party shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. 

8.4.2. Settlement of Third Party Claims. The Party that controls the defense of a given claim shall also have the right to
control settlement of such claim; provided, however, that (a) no settlement shall be entered into by such controlling Party without the prior written consent of the non-controlling Party if such settlement would adversely affect
or diminish the rights and benefits of the non-controlling Party under this Agreement, impose any new obligations or adversely affect any obligations of the non-controlling Party under this Agreement, or adversely affect the validity or
enforceability of the Patents or other intellectual property rights of such non-controlling Party and (b) the controlling Party shall not be entitled to settle any such Third Party claim by granting a license or covenant not to sue under or
with respect to the non-controlling Party’s intellectual property rights without the prior written consent of the non-controlling Party. 
 8.4.3. Allocation of Costs. Each Party shall bear its own costs and expenses relating to any defense pursuant to this Section 8.4. Any damages or other amounts 

 

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

collected shall be first allocated to reimburse the Party that has exercised its right to control the defense of the claim for its costs and expenses in making such recovery, and second to
reimburse the other Party for its costs and expenses in making such recovery. Any remainder after such reimbursement is made shall [*] under this Agreement with respect to the Licensed Product. 

8.4.4. Assistance. Each Party shall provide to the other Party all reasonable assistance requested by the other Party in
connection with any action, claim or suit under this Section 8.4, at the requesting Party’s expense, including allowing such other Party access to the assisting Party’s files and documents and to the assisting Party’s personnel
who may have possession of relevant information. In particular, the assisting Party shall promptly make available to the other Party all information in its possession or control that it is aware shall assist the other Party in responding to any such
action, claim or suit. 
 8.5 Invalidity or Unenforceability Defenses or Actions. 

8.5.1. Third Party Defense or Counterclaim. If a Third Party asserts, as a defense or as a counterclaim in any infringement action
under Section 8.3, that any Lupin Patent, Lupin Improvement Patent, Salix Patent, or Joint Patent is invalid or unenforceable, then the Party pursuing such infringement action shall promptly give notice to the other Party. With respect to the
Lupin Patents, the Lupin Improvement Patents, and the Joint Platform Patents, Lupin shall have the first right, but not the obligation, through counsel, in the case of any such Patent that is reasonably useful or necessary for the Exploitation of
the Licensed Product, reasonably acceptable to Salix, to respond to such defense or defend against such counterclaim (as applicable) and, if Salix (or its Sublicensees or any of its or their respective Affiliates) is pursuing the applicable
infringement action under Section 8.3, Salix (or its Sublicensees or any of its or their respective Affiliates) shall allow Lupin to control such response or defense (as applicable). With respect to the Salix Patents and the Joint Patents other
than the Joint Platform Patents, Salix shall have the first right, but not the obligation, through counsel reasonably acceptable to Lupin, to respond to such defense or defend against such counterclaim (as applicable) and, if Lupin is pursuing the
applicable infringement action under Section 8.3, Lupin shall allow Salix to control such response or defense (as applicable). Any costs and expenses with respect to such response or defense against such counterclaim shall be borne by the Party
controlling such response or defense. If either Party (and such Party’s licensors, to the extent permitted by its agreements therewith, and Sublicensees, if any) determines not to assume or fails to assume such defense within relevant
timeframes, the other Party shall, at its sole cost and expense, have the right to defend against such action or claim; provided that Salix’s right to defend against actions or claims relating to any Lupin Patent, Lupin Improvement
Patent or Joint Platform Patent shall be limited to actions or claims relating to any such Patent that is reasonably useful or necessary for the Exploitation of the Licensed Product; provided further that such other Party shall obtain the
written consent of Lupin, with respect to the Lupin Patents, the Lupin Improvement Patents and the Joint Patents, or Salix, with respect to the Salix Patents and the Joint Patents, prior to ceasing to defend, settling or otherwise compromising any
such action or claim, such consent not to be unreasonably withheld or delayed.

 8.5.2. Third Party Declaratory Judgment or Similar Action. If a Third Party asserts,
in a declaratory judgment action or similar action or claim filed by such Third Party, that any Lupin Patent, Lupin Improvement Patent, Salix Patent, or Joint Patent is invalid or unenforceable, then the Party first becoming aware of such action or
claim shall promptly give notice to the other Party. With respect to the Lupin Patents, the Lupin Improvement Patents, and the Joint Platform Patents, Lupin shall have the first right, but not the obligation, through counsel, in the case of any such
Patent that is reasonably useful or necessary for the Exploitation of the Licensed Product, reasonably acceptable to Salix, to defend against such action or claim. With respect to the Salix Patents and the Joint Patents other than the Joint Platform
Patents, Salix (or its Sublicensees or any of its or their respective Affiliates) shall have the first right, but not the obligation, through counsel reasonably acceptable to Lupin, to defend against such action or claim. Any costs and expenses with
respect to such defense shall be borne by the Party controlling such response or defense. If either Party determines not to assume such defense or fails to assume such defense within ninety (90) days (or twenty-five (25) days in the case
of an action brought under the Hatch-Waxman Act or within the timeframe of any other relevant regulatory or statutory framework that may govern) of learning of the action, the other Party shall, at its sole cost and expense, have the right to defend
against such action or claim; provided that Salix’s right to defend against actions or claims relating to any Lupin Patent, Lupin Improvement Patent or Joint Platform Patent shall be limited to actions or claims relating to any such
Patent that is reasonably useful or necessary for the Exploitation of the Licensed Product; provided further that such other Party shall obtain the written consent of Lupin, with respect to the Lupin Patents, the Lupin Improvement Patents, or
the Joint Patents, or Salix, with respect to the Salix Patents or the Joint Patents, prior to ceasing to defend, settling or otherwise compromising any such action or claim, such consent not to be unreasonably withheld or delayed. 

8.5.3. Assistance. Each Party shall provide to the other Party all reasonable assistance requested by the other Party in
connection with any action, claim or suit under this Section 8.5, at the requesting Party’s expense, including allowing such other Party access to the assisting Party’s files and documents and to the assisting Party’s personnel
who may have possession of relevant information. In particular, the assisting Party shall promptly make available to the other Party all information in its possession or control that it is aware would assist the other Party in responding to any such
action, claim or suit. 
 8.6 Third Party Licenses. If the Exploitation of Licensed Product by Salix, its Sublicensees or
any of its or their respective Affiliates hereunder infringes or misappropriates any Patent or other intellectual property right of a Third Party, such that Salix, its Sublicensees or any of its or their respective Affiliates cannot Exploit the
Licensed Product as permitted hereunder without infringing the Patent or intellectual property right of such Third Party, then Salix (or its Sublicensees or any of its or their respective Affiliates) shall have the first right, but not the
obligation, to take the lead in negotiating the terms of an appropriate license from such Third Party, provided that if Salix (or its Sublicensees or any of its or their respective Affiliates) does not take such lead, then Lupin may do so;
provided further, that the negotiating Party shall obtain the written consent of such other Party prior to entering into any such license, such consent not to be unreasonably withheld or delayed. Irrespective of the Party that actually

  
 - 44 -

 
obtains such license, Salix shall be entitled to deduct from royalties and other amounts it would otherwise owe to Lupin pursuant to Section 7.2 or 7.3 following the date after the Party
obtains such license an amount equal to the lesser of (a) [*] percent ([*]%) of the amount of (i) any (A) [*], (B) [*], and (C) [*], in each case ((A), (B) and (C)) due under any such license and (ii) [*], in each
case ((i) and (ii)) to the extent payable to such Third Party in consideration for rights [*] and (b) [*] percent ([*]%) of the amount of [*], with any excess beyond such [*] percent ([*]%) amount to be [*]; provided that,
notwithstanding the foregoing, Salix shall have no right to any such deduction with respect to [*]. 
 8.7 Product
Trademarks. 
 8.7.1. Ownership of Product Trademarks. Subject to Section 13.7.3, as between the Parties, Salix
shall own and retain all right, title and interest in and to the Product Trademarks. 
 8.7.2. Maintenance, Prosecution and
Enforcement of Product Trademarks. As between the Parties, Salix (or its Sublicensees or any of its or their respective Affiliates) shall control the registration, prosecution, maintenance, enforcement and defense of the Product Trademarks.

 8.8 Certain Matters. Notwithstanding any provision in this Agreement to the contrary, Salix shall have no right to

 8.8.1. prepare, file, prosecute or maintain any Lupin Patent, Lupin Improvement Patent, Joint Platform Patent or Joint
Product Patent outside the Territory except as otherwise provided in this Article 8, or 
 8.8.2. to control the prosecution of
any infringement relating to any Lupin Patent, Lupin Improvement Patent, Joint Platform Patent, or Joint Product Patent outside the Territory except as otherwise provided in this Article 8, 
 including, with respect to Sections 8.8.1 and 8.8.2, the initiation of such right by the delivery of applicable notice by Lupin, and, in all cases, Lupin shall cooperate reasonably with Salix, and Salix
shall keep Lupin reasonably informed in connection with such activities. 
 ARTICLE 9

 9.1.2. Adverse Event Reporting. Salix shall be responsible for reporting Adverse
Events in the Field in the Territory to the Regulatory Authorities pursuant to Applicable Law and shall provide a copy of any such reports to Lupin within five (5) days of making any such report. Lupin shall provide Salix with all information
in its possession necessary for Salix to comply with its pharmacovigilance responsibilities in the Territory. The Parties’ costs incurred in connection with receiving, recording, reviewing, communicating, reporting and responding to Adverse
Events in the Field in the Territory shall be borne by Salix. 
 9.1.3. Drug Safety Information. Salix shall have the
sole right to create and maintain a master drug safety database which shall cross-reference any and all Adverse Events occurring in the Territory. Salix shall be the sole owner of this master drug safety database. Lupin shall submit to Salix all
data collected by it with respect to Adverse Events in accordance with such timelines as may be imposed by Applicable Law and otherwise promptly. Notwithstanding the foregoing, the Parties acknowledge and agree that Lupin is responsible for creating
a similar database for Adverse Events outside the Territory and the Parties shall cooperate in providing data for both databases. 
 9.2 Recalls and Withdrawals. In the event that any Regulatory Authority issues or requests a recall, stop sale, field correction or market withdrawal or takes similar action (collectively,
“Recalls”) in connection with the Licensed Product or in the event either Party determines that an event, incident or circumstance has occurred that may result in the need for a Recall of the Licensed Product, the Party notified of
or desiring such Recall shall, within twenty-four (24) hours, advise the other Party thereof by telephone (and confirmed by email or facsimile), email or facsimile, at the telephone number, email address or facsimile number for such other Party
set forth on Schedule 9.2. Following notification of a Recall, the Parties shall meet to discuss such notification and Recall. Salix shall decide whether to conduct any such Recall (except in the case of a government-mandated Recall) in the
Field in the Territory and the manner in which any such Recall shall be conducted; and Lupin shall decide whether to conduct any such Recall (except in the case of a government-mandated Recall) outside the Territory or in the Territory outside the
Field and the manner in which any such Recall shall be conducted. Each Party shall provide a copy of all related documentation and notices to the other Party forthwith. Each Party shall provide such assistance to the other Party in its investigating
and conducting any Recall as such other Party may request. [*] shall bear the expenses of any Recall of the Licensed Product in the Field in the Territory; and [*] shall bear the expenses of any Recall of the Licensed Product outside the Territory
or in the Territory outside the Field; provided, however, that, to the extent any such Recall resulted solely from the other Party’s breach of its obligations hereunder or its gross negligence or willful misconduct, such other
Party shall bear the expenses of such Recall. 
 9.3 Pharmacovigilance Agreement. Prior to the first commercial sale of
the Licensed Product anywhere in the Territory, the Parties shall enter into a pharmacovigilance agreement reasonably acceptable to both Parties (the “Pharmacovigilance Agreement”), which shall include, among other things, mutually
acceptable guidelines and procedures for the receipt, 
  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 46 -

 
investigation, communication and exchange (as between the Parties) of safety information, such as Adverse Events, pregnancy exposure, lack of efficacy, misuse/abuse, and any other information
concerning the safety of the Licensed Product. Such guidelines and procedures will be in accordance with, and enable the Parties to fulfill regulatory reporting obligations to Regulatory Authorities. Furthermore, such agreed procedures shall be
consistent with relevant Regulatory Authority and International Conference on Harmonization (ICH) guidelines, except where said guidelines may conflict with more stringent existing local regulatory safety reporting requirements, in which case local
reporting requirements shall prevail. The Pharmacovigilance Agreement may, as necessary, contemplate the use of Third Party vendors currently used by the Parties. 
 ARTICLE 10 
 CONFIDENTIALITY AND NON-DISCLOSURE 

10.1 Product Information. Lupin recognizes that by reason of, inter alia, Salix’s status as an exclusive licensee
pursuant to the grants under Section 2.1, Salix has an interest in Lupin’s retention in confidence of certain information of Lupin. Accordingly, during the term of this Agreement, Lupin shall, and shall cause its Affiliates and its and
their respective officers, directors, employees, and agents to, keep confidential, and not publish or otherwise disclose, and not use directly or indirectly for any purpose other than to fulfill Lupin’s obligations, or exercise Lupin’s
rights, hereunder or under the API Supply Agreement or the Finished Product Supply Agreement, any data or information owned or possessed by Lupin or any of its Affiliates that relates to any Designated Licensed Product for use in the Field, or the
Manufacturing, Development or Commercialization of any of the foregoing (the “Product Information”); except to the extent (a) Lupin’s Product Information is in the public domain through no fault of Lupin or its Affiliates
or any of its or their respective officers, directors, employees, or agents; (b) such disclosure or use is expressly permitted under Section 10.4, or (c) such disclosure or use is at such time otherwise expressly permitted by the
terms of this Agreement. For purposes of Section 10.4, Salix shall be deemed to be the disclosing Party with respect to Lupin’s Product Information under Section 10.4 and Lupin shall be deemed to be the receiving Party with respect
thereto. For further clarification, (a) without limiting this Section 10.1, to the extent Lupin’s Product Information is disclosed by Lupin to Salix pursuant to this Agreement, such information shall, subject to the other terms and
conditions of this Article 10, also constitute Confidential Information of Lupin with respect to the use and disclosure of such data or information by Salix (and Lupin shall be deemed to be the disclosing Party with respect to such Product
Information under Section 10.4 and Salix shall be deemed to be the receiving Party with respect thereto), but (b) the disclosure by Lupin to Salix of Lupin’s Product Information shall not cause such information to cease to be subject
to the provisions of this Section 10.1 with respect to the use and disclosure of such Confidential Information by Lupin. In the event this Agreement expires or is terminated, this Section 10.1 shall have no continuing force or effect with
respect to the use or disclosure of Product Information, but Product Information that was disclosed by Salix to Lupin hereunder prior to such expiration or termination of this Agreement shall continue to be Confidential Information of Salix and
subject to the terms of Sections 10.2, 10.4, 10.6 and 10.8 for purposes of the surviving provisions of this Agreement.

 10.2 Confidentiality Obligations. At all times during the term and for a period of
[*] ([*]) years following termination or expiration hereof, each Party shall, and shall cause its Affiliates and Sublicensees and its and their respective officers, directors, employees and agents to, keep completely confidential and not publish or
otherwise disclose and not use, directly or indirectly, for any purpose, any Confidential Information furnished or otherwise made known to it, directly or indirectly, by the other Party, except to the extent such disclosure or use is expressly
permitted by the terms of this Agreement or is reasonably necessary for the performance of this Agreement. “Confidential Information” means any information provided by one Party to the other Party, whether before or after the
Amendment Effective Date, relating to the Licensed Delivery Technology, Rifaximin, the Licensed Product (including any Regulatory Documentation and Regulatory Authorizations and any information or data contained therein), any Development or
Commercialization of the Licensed Product or the scientific, regulatory or business affairs or other activities of either Party and specifically includes the terms of this Agreement. Notwithstanding the foregoing, (a) all Regulatory
Documentation transferred by Lupin to Salix shall be deemed to be the Confidential Information of Salix, and Salix shall be deemed to be the disclosing Party and Lupin shall be deemed to be the receiving Party with respect thereto, and
(b) Joint Know-How shall be deemed to be the Confidential Information of both Parties, and both Parties shall be deemed to be the receiving Party and the disclosing Party with respect thereto. Notwithstanding the foregoing, Confidential
Information shall not include any information that: 
 10.2.1. is or hereafter becomes part of the public domain by public use,
publication, general knowledge or the like through no wrongful act, fault or negligence on the part of the receiving Party; 

10.2.2. can be demonstrated by documentation or other competent proof to have been in the receiving Party’s possession prior to
disclosure by the disclosing Party without any obligation of confidentiality with respect to said information; provided that the foregoing exception shall not apply with respect to Regulatory Documentation or Joint Know-How; 

10.2.3. is subsequently received by the receiving Party from a Third Party who is not bound by any obligation of confidentiality with
respect to said information; 
 10.2.4. has been published by a Third Party (other than a Sublicensee) or otherwise enters the
public domain through no fault of the receiving Party in breach of this Agreement; or 
 10.2.5. can be demonstrated by
documentation or other competent evidence to have been independently developed by or for the receiving Party without reference to the disclosing Party’s Confidential Information; provided that the foregoing exception shall not apply with
respect to Regulatory Documentation or Joint Know-How. 
  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 48 -

 Specific aspects or details of Confidential Information shall not be deemed to be within the public domain
or in the possession of the receiving Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the receiving Party. Further, any combination of Confidential Information
shall not be considered in the public domain or in the possession of the receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the receiving Party unless the combination
and its principles are in the public domain or in the possession of the receiving Party. Notwithstanding the foregoing, Lupin may, for research or Development purposes, disclose Confidential Information of a technical nature to a Third Party
licensee of Lupin Technology if (i) such Third Party licensee enters into a confidentiality agreement with Lupin at least as restrictive as this Article 10 and (ii) such license contemplates use of the Confidential Information for sales of
products substantially similar to the Licensed Bioadhesive Product outside the Territory or in the Territory but outside the Field. 
 10.3 Trade Secrets. Notwithstanding the time limitation provided in Section 10.2, Confidential Information that constitutes a trade secret under New York law or the Uniform Trade Secrets Act
and is so identified to the receiving Party by the disclosing Party in writing shall be maintained confidential indefinitely. 

10.4 Permitted Disclosures. Each Party may disclose Confidential Information to the extent that such disclosure is: 

10.4.1. Made in response to a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional,
state, provincial or local governmental or regulatory body of competent jurisdiction or, if in the reasonable opinion of the receiving Party’s legal counsel, such disclosure is otherwise required by law; provided, however, that
the receiving Party shall first have given notice to the disclosing Party and given the disclosing Party a reasonable opportunity to quash such order and to obtain a protective order requiring that the Confidential Information and documents that are
the subject of such order be held in confidence by such court or agency or, if disclosed, be used only for the purposes for which the order was issued; and provided further that if a disclosure order is not quashed or a protective order is
not obtained, the Confidential Information disclosed in response to such court or governmental order shall be limited to that information which is legally required to be disclosed in response to such court or governmental order; 

10.4.2. Made by the receiving Party to the Regulatory Authorities as required in connection with any filing in relation to a Regulatory
Authorization; provided, however, that reasonable measures shall be taken to assure confidential treatment of such information; 
 10.4.3. Made by the receiving Party to its Sublicensees or its or their respective Affiliates or by the receiving Party, its Sublicensees or its or their respective Affiliates to its or their respective
attorneys, auditors, advisors, consultants, contractors, suppliers, service

providers, customers, distributors, collaboration partners, licensees or licensors, in each case whether existing or prospective, and other Third Parties as may be necessary or useful in
connection with the Exploitation of the Licensed Product or otherwise in connection with the performance of its obligations or exercise of its rights as contemplated by this Agreement; provided, however, that such Persons shall be
subject to obligations of confidentiality and non-use with respect to such Confidential Information substantially similar to the obligations of confidentiality and non-use of the receiving Party pursuant to this Article 10; provided further
that each Party shall remain responsible for any failure by its Sublicensees or its or their respective Affiliates, attorneys, auditors, advisors, consultants, contractors, suppliers, service providers, customers, distributors, collaboration
partners, licensees or licensors or other permitted Third Party disclosees to treat such Confidential Information as required under this Article 10 (as if such Sublicensees, Affiliates, attorneys, auditors, advisors, consultants, contractors,
suppliers, service providers, customers, distributors, collaboration partners, licensees or licensors and other permitted Third Party disclosees were Parties directly bound to the requirements of this Article 10). 

10.4.4. Made by the receiving Party to existing or potential acquirers or merger candidates; investment bankers; or existing or
potential investors, venture capital firms or other financial institutions or investors for purposes of obtaining financing, each of whom prior to disclosure must be bound by obligations of confidentiality and non-use with respect to such
Confidential Information substantially similar to the obligations of confidentiality and non-use of the receiving Party pursuant to this Article 10; provided, however, that Lupin shall make no such disclosure to a Salix Competitor,
without obtaining Salix’s prior consent in writing. 
 10.5 Use of Name. Neither Party shall mention or otherwise
use the name, insignia, symbol, Trademark, trade name or logotype of the other Party (or any abbreviation or adaptation thereof) in any publication, press release, marketing and Promotional Materials or other form of publicity without the prior
written approval of such other Party in each instance. The restrictions imposed by this Section shall not prohibit either Party from making any disclosure identifying the other Party (a) as a counterparty to this Agreement to its investors
(b) that is required by Applicable Law or the requirements of a national securities exchange or another similar regulatory body (provided that any such disclosure shall be governed by this Article 10), or (c) with respect to
which consent has previously been obtained. Further, the restrictions imposed on each Party under this Section 10.5 are not intended, and shall not be construed, to prohibit a Party from identifying the other Party in its internal business
communications, provided that any Confidential Information in such communications remains subject to this Article 10. 
 10.6 Press Releases. Press releases or other similar public communication by either Party relating to this Agreement, including upon termination of this Agreement by Salix pursuant to
Section 13.3, shall be approved in advance by the other Party, which approval shall not be unreasonably withheld or delayed, except for those communications required by Applicable Law (provided that the other Party is given a reasonable
opportunity to review and comment on any such press release or public communication in advance thereof), disclosures of information for which consent has previously been obtained, information that has been previously disclosed publicly, or as
otherwise set forth in this Agreement.

 10.7 Patient Information. The Parties agree to abide (and to cause their respective
Affiliates and Sublicensees to abide) and to take (and to cause their respective Affiliates and Sublicensees to take) all reasonable and appropriate actions to ensure that all Third Parties conducting or assisting with any clinical development
activities hereunder in accordance with, and subject to the terms of, this Agreement, shall abide, to the extent applicable, by all Applicable Law concerning the confidentiality or protection of patient identifiable information or patient’s
protected health information, including the regulations at 45 C.F.R. Parts 160 and 164 and where relevant, the applicable national laws implementing the European Parliament and Council Directive 95/46/EC on the protection of individuals with regard
to the processing of personal data and on the free movement of such data of 24 October 1995 and any other Applicable Law, in the course of their performance under this Agreement. 

10.8 Publications. Each Party recognizes that the publication of papers regarding results of and other information regarding
activities under this Agreement, including oral presentations and abstracts, may be beneficial to both Parties, provided such publications are subject to reasonable controls to protect Confidential Information. In particular, it is the intent
of the Parties to maintain the confidentiality of any Confidential Information included in any Patent application until such Patent application has been filed. Accordingly, each Party shall have the right to review and approve any paper proposed for
publication by the other Party, including any oral presentation or abstract, that contains Clinical Data or pertains to results of Clinical Trials or other studies with respect to the Licensed Product or includes other data generated under this
Agreement or which includes Confidential Information of the other Party. Before any such paper is submitted for publication or an oral presentation is made, the publishing or presenting Party shall deliver a complete copy of the paper or materials
for oral presentation to the other Party at least forty-five (45) days prior to submitting the paper to a publisher or making the presentation. The other Party shall review any such paper and give its comments to the publishing Party within
thirty (30) days of the delivery of such paper to the other Party. With respect to oral presentation materials and abstracts, the other Party shall make reasonable efforts to expedite review of such materials and abstracts, and shall return
such items as soon as practicable to the publishing or presenting Party with appropriate comments, if any, but in no event later than thirty (30) days from the date of delivery to the other Party. Failure to respond within such thirty
(30) days shall be deemed approval to publish or present. If approval is not given or deemed given, either Party may refer the Dispute in accordance with Section 14.7 for resolution. Notwithstanding the foregoing, the publishing or
presenting Party shall comply with the other Party’s request to delete references to such other Party’s Confidential Information in any such paper and shall withhold publication of any such paper or any presentation of same for an
additional sixty (60) days in order to permit the Parties to obtain patent protection if either Party deems it necessary. Any publication shall include recognition of the contributions of the other Party according to standard practice for
assigning scientific credit, either through authorship or acknowledgement, as may be appropriate. Each Party shall use commercially reasonable efforts to cause investigators and institutions participating in Clinical Trials for the Licensed Product
with which it contracts to agree to terms substantially similar to those set forth in this Section 10.8, which efforts shall satisfy such Party’s obligations under this Section 10.8 with respect to such investigators and institutions.

 ARTICLE 12 
 INDEMNIFICATION 
 12.1 Indemnification by Salix. Salix shall
indemnify Lupin, its Affiliates and their respective directors, officers, employees and agents, and defend and save each of them harmless, from and against any and all losses, damages, liabilities, costs, fees and expenses (including reasonable
attorneys’ fees and expenses) (collectively, “Losses”) in connection with any and all suits, actions, investigations, claims or demands of Third Parties (collectively, “Third Party Claims”) arising from or
occurring as a result of: (a) the breach by Salix, its Sublicensees or any of its or their respective Affiliates of any representation, warranty, covenant, undertaking or other term contained in this Agreement; (b) the negligence or
willful misconduct on the part of Salix, its Sublicensees or any of its or their respective Affiliates in performing its or their obligations under this Agreement; (c) the Exploitation by Salix, its Sublicensees or any of its or their
respective Affiliates of the Licensed Product; (d) [*]; or (e) [*]; except in cases (a), (b) and (c), for those Losses for which Lupin has an obligation to indemnify Salix pursuant to Section 12.2 hereof, as to which
Losses each Party shall indemnify the other to the extent of their 
  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 55 -

 
respective responsibility for the Losses; provided, however, that Salix shall not be obligated to indemnify Lupin for any Losses under (a), (b), or (c) to the extent that such
Losses arise as a result of negligence or willful misconduct on the part of Lupin or any of its Affiliates or Sublicensees. 

12.2 Indemnification by Lupin. Lupin shall indemnify Salix, its Affiliates and their respective directors, officers, employees and
agents, and defend and save each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims arising from or occurring as a result of: (a) the breach by Lupin, its licensees or its Sublicensees or any
of its or their respective Affiliates of any representation, warranty, covenant, undertaking or other term contained in this Agreement; (b) the negligence or willful misconduct on the part of Lupin, its licensees or its Sublicensees or any of
its or their respective Affiliates in performing its or their obligations under this Agreement; or (c) the Exploitation by Lupin, its licensees (other than Salix) or its Sublicensees or any of its or their respective Affiliates of the Licensed
Product, except in each case ((a), (b) and (c)) for those Losses for which Salix has an obligation to indemnify Lupin pursuant to Section 12.1 hereof, as to which Losses each Party shall indemnify the other to the extent of their
respective responsibility for the Losses; provided, however, that Lupin shall not be obligated to indemnify Salix for any Losses to the extent that such Losses arise as a result of negligence or willful misconduct on the part of Salix
or any of its Affiliates or Sublicensees. 
 12.3 Notice of Claim. All indemnification claims in respect of a Party, its
Affiliates or their respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party shall give the indemnifying Party prompt notice (an
“Indemnification Claim Notice”) of any Losses or discovery of fact upon which such indemnified Party intends to base a request for indemnification under Section 12.1 or 12.2, but in no event shall the indemnifying Party be
liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is
known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims. 

12.4 Control of Defense. The defense of any Third Party Claim shall be conducted as follows: 

12.4.1. Control by Indemnifying Party. At its option, the indemnifying Party may assume the defense of any Third Party Claim by
giving notice to the Indemnified Party within thirty (30) days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party shall not be construed
as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified
Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event
the indemnifying Party assumes the defense of a Third 

  
 - 56 -

 
Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection
with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 12.4.2, the indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently
incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the
Indemnified Party from and against the Third Party Claim, the Indemnified Party shall reimburse the indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any Third Party Claims incurred by the
indemnifying Party in its defense of the Third Party Claim. 
 12.4.2. Right to Participate in Defense. Without limiting
Section 12.4.1 above, any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment
shall be at the Indemnified Party’s own expense unless (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed to assume the defense and employ counsel in
accordance with Section 12.4.1 (in which case the Indemnified Party shall control the defense) or (c) the interests of the indemnitee and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit
the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles. 
 12.4.3.
Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that shall not result in the Indemnified Party’s becoming subject to injunctive or other relief or
otherwise adversely affecting the business of the Indemnified Party in any manner, and as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party shall
have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in
connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 12.4.1, the indemnifying Party shall have authority to consent to the entry of any judgment, enter into
any settlement or otherwise dispose of such Loss, provided it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The indemnifying Party shall not be liable for any
settlement or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no
Indemnified Party shall, and the Indemnified Party shall ensure that no indemnitee shall, admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such
consent not to be unreasonably withheld or delayed. 
 12.4.4. Cooperation. Regardless of whether the indemnifying Party
chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall 

  
 - 57 -

 
cause each indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery
proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified
Party of, records and information that are reasonably relevant to such Third Party Claim, and making indemnitees, employees and agents available on a mutually convenient basis to provide additional information and explanation of any material
provided hereunder, and the indemnifying Party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith. 
 12.4.5. Expenses. Except as provided above, the costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim shall be reimbursed
on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately
held not to be obligated to indemnify the Indemnified Party. 
 12.5 Limitation on Damages and Liability. EXCEPT IN
CIRCUMSTANCES OF [*] OR INTENTIONAL MISCONDUCT BY A PARTY OR ITS AFFILIATES OR SUBLICENSEES (OR WITH RESPECT TO SALIX, ITS DISTRIBUTORS), NEITHER PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, PUNITIVE, INDIRECT,
INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS, MILESTONES OR ROYALTIES, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING OUT OF (A) THE DEVELOPMENT,
MANUFACTURE, USE OR SALE OF THE LICENSED PRODUCT UNDER THIS AGREEMENT, (B) THE USE OF OR REFERENCE TO THE PATENTS, KNOW-HOW OR REGULATORY DOCUMENTATION LICENSED HEREUNDER OR (C) ANY BREACH OF OR FAILURE TO PERFORM ANY OF THE PROVISIONS OF
THIS AGREEMENT; PROVIDED, HOWEVER, THAT THIS EXCLUSION IS NOT INTENDED TO EXCLUDE DAMAGES OWED PURSUANT TO ARTICLE 10 OR TO THIRD PARTIES PURSUANT TO SECTION 12.1 OR 12.2, REGARDLESS OF TYPE. 

12.6 Insurance. Each Party shall maintain, at its sole cost and expense, an adequate liability insurance or self-insurance program
(including product liability insurance) to protect against potential liabilities and risk arising out of activities to be performed under this Agreement and any agreement related hereto and upon such terms (including coverages, deductible limits and
self-insured retentions) as are customary in the pharmaceutical industry generally for the activities to be conducted by such Party under this Agreement. Such liability insurance or self-insurance program shall insure against all types of liability,
including personal injury, physical injury or property damage arising out of the Exploitation of the Licensed Product. This Section 12.6 shall not create any limitation on a Party’s liability to the other under this Agreement.

the Covered Product pursuant to Section 7.3 and (b) the tenth anniversary of the Amendment Effective Date. Upon expiration of this Agreement pursuant to the preceding sentence, the license grants to Salix in Section 2.1 shall become
non-exclusive, fully paid-up, perpetual and irrevocable. 
 13.2 Termination for Material Breach. Any material failure by
a Party (the “Breaching Party”) to comply with any of its material obligations contained in this Agreement shall entitle the Party not in default to give to the Breaching Party notice specifying the nature of the default, requiring
the Breaching Party to make good or otherwise cure such default, and stating its intention if such default is not cured to terminate this Agreement. If such default is not cured within [*] ([*]) days after the receipt of such notice (or, if such
default cannot be cured within such [*] ([*]) day period, if the Breaching Party does not commence actions to cure such default within such period and thereafter diligently continue such actions or if such default is not otherwise cured within [*]
([*]) days after the receipt of such notice, except in the case of a payment default, as to which the Breaching Party shall have only a thirty (30) day cure period), the Party not in default shall be entitled, on notice to the Breaching Party,
without prejudice to any other rights conferred on it by this Agreement, and in addition to any other remedies available to it at law or in equity, to terminate this Agreement in its entirety. 

13.3 Other Termination by Salix. 
 13.3.1. Salix may terminate this Agreement immediately upon notice to Lupin in the event that any Regulatory Authority in the United States requires or causes the withdrawal of a Salix Prescription

 13.5 Termination by Lupin. Lupin may terminate this Agreement immediately upon notice to Salix in the event that the API Supply Agreement is terminated other than by Salix pursuant to
Section 6.2(c)(ii) thereof. 
 13.6 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this
Agreement by Lupin or Salix are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the United
States Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the United States Bankruptcy Code. The Parties further agree
that, in the event of the commencement of a bankruptcy proceeding by or against a Party under the United States Bankruptcy Code, the Party hereto that is not a party to such proceeding shall be entitled to a complete duplicate of (or complete access
to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in the non-subject Party’s possession, shall be promptly delivered to it (a) following any such commencement of a
bankruptcy proceeding upon the non-subject Party’s written request therefor, unless the Party subject to such proceeding continues to perform all of its obligations under this Agreement or (b) if not delivered under clause (a) above,
following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party. 
 13.7 Licenses and Assignments Upon Termination. Upon any termination of this Agreement pursuant to Section 13.2, 13.3, 13.4, or 13.5: 

13.7.1. the licenses granted by Lupin to Salix under Section 2.1 shall, subject to the second sentence of
Section 7.3.2(a) and the second sentence of Section 7.3.2(b), terminate in their entirety; 
 13.7.2. the
licenses granted by Salix to Lupin under Section 2.4 shall be revised such that Salix shall, and does hereby, grant, and shall cause its Sublicensees and its and their respective Affiliates to so grant, to Lupin a non-exclusive, perpetual,
irrevocable, worldwide, [*] license, with the right to grant sublicenses through multiple tiers of sublicensees, without the consent of Salix, under the Salix Technology to Exploit any Designated Licensed Product for all purposes; and 

 

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 60 -

 13.7.3. Salix shall, and does hereby, and shall cause its Sublicensees and its and their
respective Affiliates to, transfer, convey, assign and deliver to Lupin, and Lupin hereby accepts, all right, title and interest in and to, (a) any Designated Licensed Product, including any related Information and inventions, and any
Improvements with respect thereto (including Salix Know-How and all material aspects of Confidential Information Controlled by Salix as of the date of termination with respect to such Designated Licensed Product), (b) any Regulatory
Authorizations and related Regulatory Documentation and correspondence with Regulatory Authorities with respect to any Designated Licensed Product, (c) any Product Trademarks, any other Trademarks (including any goodwill associated therewith),
any generic names and any domain names incorporating the same that were used by, or developed for use by, Salix in connection with any Designated Licensed Product, and (d) to the extent requested by Lupin in writing, any agreements with any
Third Parties with respect to any Designated Licensed Product (including agreements with contract research organizations, clinical sites and investigators). 
 13.8 Additional Consequences of Termination. 
 13.8.1. Sale of
Inventory.  
 (a) In the event of any termination of this Agreement, Salix may continue to sell its existing
inventories and any work-in-process of the Licensed Bioadhesive Product until the occurrence of either: (a) Salix’s completion of the transfer to Lupin of all Regulatory Authorizations and related Regulatory Documentation for the Licensed
Bioadhesive Product and completion of performance under all then-existing contracts with Third Parties for the marketing, sale or manufacture of the Licensed Bioadhesive Product, or (b) Lupin’s directing Salix to halt all sales of the
Licensed Bioadhesive Product by notice. If either such event occurs prior to the sale of all of Salix’s inventories and work-in-process of the Licensed Bioadhesive Product and the performance by Salix of its obligations under such Third Party
contracts, then Salix [*], and Lupin shall [*]. 
 (b) In the event of any termination of this Agreement, Salix may continue to
sell its existing inventories and any work-in-process of Licensed Product other than Licensed Bioadhesive Product until such inventories of finished product and work-in-process are exhausted. 

13.8.2. Return of Lupin Materials and Information. Upon the expiration or any termination of this Agreement, Salix, at the
request of Lupin, shall return or, at the election of Salix, use reasonable efforts to destroy, and thereafter provide to Lupin written certification evidencing such destruction, all data, files, records and other materials in its possession or
control relating to the Lupin Technology, or containing or comprising Lupin’s Information and inventions or other Confidential Information (except one copy of which may be retained solely for archival purposes) with respect to the Licensed
Product; provided, that notwithstanding the foregoing, Salix shall be required to return, and may not destroy, any Regulatory Documentation related to the Licensed Bioadhesive Product.

 - 61 -

 13.8.3. Effect of Termination on Sublicenses Granted by Salix. Any and all
sublicense agreements entered into by Salix or any of its Affiliates with a Sublicensee pursuant to Section 2.2 shall survive the termination of this Agreement, except to the extent that any such Sublicensee under any such sublicense agreement
is in material breach of this Agreement or such sublicense agreement, in which case Lupin shall have the right to terminate any such sublicense agreement. Salix shall, at the request of Lupin, assign any such sublicense agreement (to the extent not
terminated pursuant to the preceding sentence) to Lupin or its Affiliates and, upon such assignment, Lupin or its Affiliates, as applicable, shall assume such sublicense agreement, as applicable. For clarity, any sublicense agreement entered into by
Salix with any of its Affiliates shall terminate upon the termination of this Agreement. 
 13.8.4. Milestone Payments;
Royalties. Following any termination of this Agreement, Salix shall not be responsible for (a) any milestone payments for milestone events that are achieved under Section 7.1.2 following the effective date of such termination or
(b) any royalty payments that accrue under Section 7.3 following the effective date of such termination, except in each case (both (a) and (b)) with respect to any sales of the Covered Product made by Salix, either itself or through
an Affiliate, Sublicensee or Sublicensee’s Affiliate, pursuant to Section 13.8.1. 
 13.8.5. Assistance.
Without limiting Lupin’s rights under other provisions of this Article 13, in the event of any termination of this Agreement, Salix shall, and shall cause its Sublicensees and its and their respective Affiliates to, at the request and expense
of Lupin, provide Lupin with such assistance as is reasonably necessary to effectuate a smooth and orderly transition of any Development, Commercialization and other Exploitation activities relating to the Licensed Bioadhesive Product, including any
ongoing Clinical Trials or Post Approval Studies, to Lupin or its designee so as to minimize any disruption of such activities. 
 13.8.6. Royalties to Salix. In consideration of the license rights granted by Salix to Lupin under this Article 13 and the assignment of Regulatory Authorizations and related Regulatory
Documentation as contemplated by this Article 13, if a Designated Licensed Product has received its Initial Regulatory Authorization, then Lupin shall pay to Salix for such Designated Licensed Product sold by Lupin, its licensees or Sublicensees or
its or their respective Affiliates in the Territory a royalty of [*] percent ([*]%) of Net Sales (substituting Lupin for Salix in the definition thereof) during each full or partial Calendar Year from the termination of this Agreement until the
tenth (10th) anniversary of the effective date of such termination. Subject to the royalties for which provision is made in the preceding sentence, such Net Sales shall be the absolute property of Lupin. The royalties contemplated by this
Section 13.8.6 shall be payable by Lupin to Salix in accordance with the provisions of Sections 7.3.4, 7.3.5, 7.5, 7.6 and 7.7 mutatis mutandis and Section 14.18.

 13.8.7. Accrued Rights. Termination or expiration of this Agreement for any reason
shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to such termination or expiration, including under Section 7.4. Such termination or expiration shall not relieve a Party from obligations that are
expressly indicated to survive the termination or expiration of this Agreement. 
 13.8.8. Payments to Lupin. In the
event that Salix should terminate this Agreement pursuant to Section 13.3.3 prior to the third anniversary of the Amendment Effective Date (an “Early Termination”), the Parties acknowledge and agree that such Early Termination
will cause Lupin to suffer damages in an amount that is uncertain, not readily ascertainable and incapable of accurate calculation resulting from (a) the efforts and resources expended by Lupin in performance and contemplation of future
performance under this Agreement and (b) Lupin’s forgoing other commercial opportunities because of this Agreement. On this basis, the Parties further acknowledge and agree that in the event of an Early Termination, Salix shall pay to
Lupin an amount equal to the amount, if any, by which [*] Dollars ($[*]) exceeds (a) the sum of (i) Creditable Consideration paid or accrued through the date of termination plus (ii) any amounts paid or accrued through the date of
termination pursuant to Section 7.4.1 as Minimum Consideration Quarterly Reconciliation Payments plus (ii) any amounts paid or accrued through the date of termination pursuant to Section 7.4.2(a) as Minimum Consideration Annual
Reconciliation Payments, less (b) any amounts paid or accrued through the date of termination pursuant to Section 7.4.2(b) as Minimum Consideration Annual Reconciliation Refunds (the “Early Termination Fee”). The Parties
acknowledge that the Early Termination Fee has been agreed upon, after negotiation, as a reasonable estimate of an amount to compensate Lupin for the efforts and resources expended and opportunities foregone by Lupin. The Early Termination Fee shall
be Lupin’s sole and exclusive remedy in respect of any Early Termination of this Agreement by Salix and the Early Termination Fee is, therefore, not a penalty but rather constitutes liquidated damages in a reasonable amount that will compensate
Lupin for the efforts and resources expended and opportunities foregone by Lupin. Nothing in this Section 13.8.8 shall limit any other rights or remedies of Lupin or Salix under this Agreement arising from the failure of either Party to comply
with its obligations under this Agreement.

 ARTICLE 14 
 MISCELLANEOUS 
 14.1 Force Majeure. Neither Party shall be held
liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or
delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist
acts, insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental
authority; provided, that the requirement to engage in negotiations with or make payment to a Third Party listed on Schedule 8.6 to procure intellectual property rights necessary for the performance of a Party’s obligations
hereunder shall not be considered a force majeure event under this Section 14.1. The non-performing Party shall notify the other Party of such force majeure within [*] ([*]) days after such occurrence by giving notice to the other Party stating
the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use
commercially reasonable efforts to remedy its inability to perform. In the event that such force majeure event lasts for a continuous period of more than [*] ([*]) days, such suspension of performance shall be deemed a material breach of this
Agreement and such other Party shall have the right to terminate this Agreement pursuant to Section 13.2. 
 14.2 Export
Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on related to the Parties from time to time. Each Party agrees
that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export
license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity in accordance with Applicable Law. 

14.3 Subcontractors. Salix and Lupin shall each have the right to subcontract any of its Development and Commercialization
activities with respect to the Licensed Product to a Third Party. Each Party shall remain solely responsible for all costs and expenses associated with its use of subcontractor(s) hereunder. 

14.4 Assignment. Without the prior written consent of the other Party hereto, neither Party shall sell, transfer, assign,
delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party may, without such consent,
assign or transfer this Agreement or any of its rights and obligations hereunder to (a) an Affiliate of such 
  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 - 64 -

 
Party; or (b) to any Third Party with which it merges or consolidates, or to which it transfers all or substantially all of its assets to which this Agreement relates if in any such event
(i) the assigning Party (provided that it is not the surviving entity) remains jointly and severally liable with the relevant Affiliate or Third Party assignee under this Agreement, and (ii) the relevant Affiliate assignee, Third Party
assignee or surviving entity assumes in writing all of the assigning Party’s obligations under this Agreement. Any attempted assignment or delegation in violation of the preceding sentence shall be void and of no effect. All validly assigned
and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Lupin or Salix, as the case may be. In the event either Party
seeks and obtains the other Party’s consent to assign or delegate its rights or obligations to another party, the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement. Notwithstanding the
foregoing, Lupin shall have the right, from time to time and without the necessity of providing notice to or obtaining the consent of, Salix, to delegate, assign, or subcontract to any Affiliate, certain of Lupin’s rights or responsibilities
under this Agreement. In all cases, Lupin shall remain the contract Party under the Agreement and shall remain responsible to Salix for the performance of all such obligations under this Agreement. 

14.5 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future
law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or
by its severance herefrom and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid
or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by applicable law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid or
unenforceable in any respect. 
 14.6 Governing Law, Jurisdiction, Venue and Service. 

14.6.1. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York,
excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. The Parties agree to exclude the application to this Agreement of
the United Nations Convention on Contracts for the International Sale of Goods. 
 14.6.2. Jurisdiction. Subject to
Sections 14.7 and 14.11, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts of the State of New York and the United States District Court for the Southern District of New York, in either case

therefrom) related thereto except in such courts. The Parties irrevocably and unconditionally waive their right to a jury trial.

New York, in either case sitting in the Borough of Manhattan in the City of New York, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any
such court has been brought in an inconvenient forum. 
 14.6.4. Service. 

(a) Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in
Section 14.8 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court. 
 (b) Lupin hereby designates, appoints and empowers Lupin Pharmaceuticals, Inc., with an office located at Harborplace Tower, 111 S. Calvert Street, 21st Floor, Baltimore, MD 21202, U.S.A., as its
designee, appointee and agent to receive, accept and forward for and on its behalf, and it properties, assets and revenues, service of any and all legal process, summons, notices and documents which may be served in any action, suit or proceeding
arising out of or relating to this Agreement or any of the transactions or services contemplated hereunder that is brought in the courts of the State of New York and the United States District Court for the Southern District of New York, in either
case sitting in the Borough of Manhattan in the City of New York, which may be made on any designee, appointee and agent in accordance with legal procedures prescribed in such courts. If for any reason such designee, appointee and agent hereunder

service of any and all legal process, summons, notices and documents out of any of the courts of the State of New York and the United States District Court for the Southern District of New York, in either case sitting in the Borough of Manhattan in
the City of New York, in any such action, suit or proceeding by serving a copy thereof upon the agent for service of process referred to in this Section 14.6.4(b) (whether or not the appointment of such agent shall for any reason prove to be
ineffective or such agent shall accept or acknowledge such service) coupled with mailing of copies thereof in accordance with Section 14.6.4(a). Lupin agrees that the failure of any such designee, appointee or agent to give any notice of such
service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. 
 14.7 Dispute Resolution. 
 14.7.1. General. If a dispute arises
between the Parties in connection with or relating to this Agreement or any document or instrument delivered in connection herewith 

  
 - 66 -

 
(other than a dispute arising under Section 4.4.8, which shall be finally and definitively resolved in accordance with Section 4.4.8) (a “Dispute”), then either Party
shall have the right to refer such Dispute to the chief executive officers of the Parties (or their designees) who shall confer for attempted resolution of the Dispute by good faith negotiations during a period of thirty (30) Business Days. Any
final decision mutually agreed to by such officers shall be conclusive and binding on the Parties. If the Dispute remains unresolved after such thirty (30)-Business Day period, then except as provided in Section 14.7.2 and with respect to
any matter for which consent or approval is assigned to the Parties jointly, either Party may, by notice to the other Party, initiate litigation for resolution of such Dispute.

 14.9 Entire Agreement; Modifications. This Agreement, together with the Schedules and Exhibits attached hereto, sets forth and constitutes the entire agreement and understanding between the Parties
with respect to the subject matter hereof and all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto, including the Original Agreement, are superseded hereby. Each Party confirms that it is
not relying on any representations or warranties of the other Party except as specifically set forth herein. No amendment, modification, release or discharge shall be binding upon the Parties unless in writing and duly executed by authorized
representatives of both Parties. 
 14.10 English Language. This Agreement shall be written and executed in, and all
other communications under or in connection with this Agreement shall be in, the English language. Any translation into any other language shall not be an official version thereof, and in the event of any conflict in interpretation between the
English version and such translation, the English version shall control. 
 14.11 Equitable Relief. The Parties
acknowledge and agree that the restrictions set forth in Sections 2.5, 8.2, 8.3, 8.4, 8.5, 8.6, and 8.7 and Article 10 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have
entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of Section 2.5, 8.2, 8.3, 8.4, 8.5, 8.6, or 8.7 or Article 10 may result in irreparable injury to such other Party
for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of Section 2.5, 8.2, 8.3, 8.4, 8.5, 8.6, or 8.7 or Article 10, the non-breaching Party shall be authorized and entitled to
obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights shall be
cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity. Both Parties agree to waive, to the maximum extent permitted by Applicable Law, any requirement that the other
(a) post a bond or other security as a condition for obtaining any such relief and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this
Section 14.11 is intended, or should be construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement. 

  
 - 69 -

 14.12 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement
may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by
either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or
otherwise. 
 14.13 No Benefit to Third Parties. The representations, warranties, covenants and agreements set forth in
this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns, and they shall not be construed as conferring any rights on any other Persons. 

14.14 Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further
instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement
or to carry out more effectively the provisions and purposes hereof, or to better assure and confirm unto such other Party its rights and remedies under this Agreement. 
 14.15 Relationship of the Parties. It is expressly agreed that Lupin, on the one hand, and Salix, on the other hand, shall be independent contractors and that the relationship between the two
Parties shall not constitute a partnership, joint venture or agency. Neither Lupin, on the one hand, nor Salix, on the other hand, shall have the authority to make any statements, representations or commitments of any kind, or to take any action,
which shall be binding on the other, without the prior written consent of the other Party to do so, such consent not to be unreasonably withheld or delayed. All persons employed by a Party shall be employees of such Party and not of the other Party
and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party. 

14.16 Performance by Affiliates. Each of Lupin and Salix acknowledges that certain obligations under this Agreement may be
performed by Affiliates of Lupin and Salix. Each of Lupin and Salix guarantees performance of this Agreement by any of its Affiliates. 
 14.17 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
This Agreement may be executed by scanned and electronically or facsimile transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were original signatures. 

14.18 Payments; Audits 
 14.18.1. Interest on Late Payments. If any payment due to a Party under this Agreement is not paid when due, then the owing Party shall pay interest thereon (before and after any judgment) at an
annual rate (but with interest accruing on a daily basis) equal to the lesser of (a) the prime rate as reported on the first Business Day of each month such payment is 

  
 - 70 -

 
overdue in The Wall Street Journal, Eastern Edition, plus [*] ([*]) percentage points, and (b) the maximum rate permitted by Applicable Law. Interest payable under this
Section 14.18.1 shall run from the day following the date upon which payment of the relevant principal sum became due through the date of payment thereof in full together with such interest. 

14.18.2. Audit. Each Party shall have the right to have an independent certified public accounting firm of internationally
recognized standing, and reasonably acceptable to the other Party, provided with access by such other Party during normal business hours, and upon reasonable prior notice, to examine only those records of such other Party (and its Affiliates and
Sublicensees) as may be reasonably necessary to determine, with respect to any Calendar Year ending not more than three (3) years prior to the auditing Party’s request, the correctness or completeness of any payment made under this
Agreement. Such examinations may not (a) be conducted more than once in any [*] ([*]) month period (unless a previous audit during such [*] ([*]) month period revealed an underpayment with respect to such period or the audited Party restates or
revises such books and records for such period) or (b) be repeated for any Calendar Year. Results of such audit shall (i) be (A) limited to information relating to the Licensed Product, (B) made available to both Parties in
writing and (C) subject to Article 10 and (ii) not reveal any specific information of the audited Party to the auditing Party other than (A) whether the audited Party is in compliance with its payment obligations under this Agreement
and (B) the amount of any additional payment owed to the auditing Party or excess payment reimbursable to the audited Party. Except as provided below, the cost of this examination shall be borne by the auditing Party, unless the audit reveals a
variance of more than five percent (5%) from the reported amounts, in which case the audited Party shall bear the cost of the audit. Unless disputed pursuant to Section 14.18.3, if such audit concludes that additional payments were owed or
that excess payments were made during such period, the audited Party shall pay the additional amounts, with interest from the date originally due as provided in Section 14.18.1, or the auditing Party shall reimburse such excess payments, with
interest from the date of original payment as provided in Section 14.18.1, within sixty (60) days after the date on which such auditor’s written report is delivered to the Parties. 

14.18.3. Audit Dispute. In the event of a Dispute of any audit under Section 14.18.2, Lupin and Salix shall work in good
faith to resolve the disagreement. If the Parties are unable to reach a mutually acceptable resolution of any such Dispute within thirty (30) days, the Dispute shall be resolved in accordance with Section 14.7. 

14.18.4. Confidentiality. The receiving Party shall treat all information subject to review under this Article 14 in accordance
with the confidentiality provisions of Article 10. 
 14.19 References. Unless otherwise specified,
(a) references in this Agreement to any Article, Section, Schedule or Exhibit shall mean references to such Article, Section, Schedule or Exhibit of this Agreement, (b) references in any section to any clause are references 

 

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

to such clause of such section and (c) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally
executed or, if subsequently varied, replaced or supplemented from time to time, as so varied, replaced or supplemented and in effect at the relevant time of reference thereto. 

14.20 Construction. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural
the singular, the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or). The captions of this Agreement are for convenience of reference only and in no way define, describe, extend
or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The term “including” as used herein shall mean including, without limiting the generality of any description preceding such term.
The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party hereto. 

14.21 Additional Agreements. 
 14.21.1. Simultaneously herewith, and as a condition to the Parties’ execution and delivery hereof, (a) the Parties are entering into the first amendment that constitutes part of the API Supply
Agreement and (b) the Parties are entering into the Finished Product Supply Agreement. 
 14.21.2. The Parties acknowledge
that they have been pursuing negotiations in respect of an agreement pursuant to which [*]. The Parties confirm their intent to continue such negotiations with a view to entering into an agreement by [*], but without thereby imposing on either Party
any obligation to enter into any such agreement or creating any legally binding obligation in respect of any such agreement or the terms thereof unless and until such agreement is fully negotiated and executed and delivered by the parties thereto.
Any failure by the Parties to enter into the agreement described in the first sentence of this Section 14.21.2 shall not in any way affect the enforceability and continued validity of this Agreement, the API Supply Agreement, or the Finished
Product Supply Agreement. 
 14.21.3. This Agreement supersedes and replaces, effective as of the Amendment Effective Date, the
provisions of the Original Agreement in their entirety. The execution and delivery of this Agreement is without prejudice to any rights that accrued to the benefit of either Party under the Original Agreement prior to the Amendment Effective Date;

undisputed portion and shall provide Lupin with written notice of the disputed portion and its reasons therefor, and Salix shall not be obligated to pay such disputed portion. The Parties shall use good faith efforts to resolve any such disputes
promptly. In the event of any inconsistency between an invoice and this Agreement, the terms of this Agreement shall control. Payment of invoices shall be made by wire transfer to an account designated in writing by Lupin in United States Dollars.
If any currency conversion shall be required in connection with any payment hereunder, such conversion shall be made each calendar quarter using an exchange rate that is the arithmetic average of the daily exchange rates (obtained as described

delivers its estimate, to such estimate, in which case the Parties shall meet thereafter to discuss in good faith the Manufacturing Costs that shall apply in respect of the Launch Year, with the result that the interim Purchase Price for the Launch
Year shall be the agreed estimated Manufacturing Costs increased by the Finished Product Markup. 
 (d) On or before
January 31 of the first Calendar Year following the Launch Year and thereafter as of January 31 of each successive Calendar Year during the Term, Lupin shall deliver to Salix a statement setting forth Lupin’s actual Manufacturing
Costs, calculated in accordance with Schedule 1.50, for the Calendar Year just ended. Such actual Manufacturing Costs multiplied by the Finished Product Markup (the “All-In Actual Cost”) for such prior Calendar Year shall
constitute the interim Purchase Price with respect to the current Calendar Year. 
 (e) The Parties shall reconcile the Purchase
Price paid by Salix in respect of each Product purchased during each Calendar Year during the Term, including the Launch Year, in accordance with the provisions of this Section 2.5(e). If the aggregate interim Purchase Price paid by Salix for
the Product purchased during the Calendar Year is within plus or minus [*] ([*]%) of the aggregate Purchase Price that would have been paid by Salix for the Product purchased during the Calendar Year had the interim Purchase Price been determined
using the All-In Actual Cost for the Calendar Year, then no reconciliation of the Purchase Price in respect of such Calendar Year will be made between the Parties. If the aggregate interim Purchase Price paid by Salix for the Product for the
Calendar Year is greater than [*] percent ([*]%) of the aggregate Purchase Price that would have been paid by Salix for the Product purchased during the Calendar Year had the interim Purchase Price been determined using the All-In Actual Cost for
such Calendar Year (the “Upper Collar”), then Lupin shall within sixty (60) days after the end of the Calendar Year reimburse Salix for amounts paid by Salix in excess of the Upper Collar. If the aggregate interim Purchase
Price paid by Salix for the Product for the Calendar Year is less than [*] percent ([*]%) of the aggregate Purchase Price that would have been paid by Salix for Product purchased during the Calendar Year had the interim Purchase Price been
determined using the All-In Actual Cost for such Calendar Year (the “Lower Collar”), then Salix shall

 -11-

 within sixty (60) days after the end of such Calendar Year pay Lupin such additional amounts as are
necessary to cause the aggregate Purchase Price paid by Salix for the Product purchased during such Calendar Year to equal the Lower Collar. 
 (f) Salix shall have the right to audit Lupin’s records, pursuant to and in accordance with Section 8.8, to confirm Lupin’s All-In Actual Cost for each Product and to establish that the
Purchase Price for the Product supplied hereunder is in compliance with the provisions of Section 2.5(b). 
 2.6
Warranty. In connection with each delivery of Product to Salix hereunder, Lupin hereby represents and warrants to Salix as of the date of the delivery of such Product to Salix as follows: (a) such Product is in conformity with the
Specifications and the Certificate of Analysis therefor provided pursuant to Section 2.2(g); (b) such Product has been Manufactured in conformance with GMP, all other Applicable Law, this Agreement and the Quality Agreement; (c) title

(including applicable inspection requirements of FDA and other Regulatory Authorities); (e) the expiration date of such Product is no earlier than [*], with such expiration date requirements to be adjusted in good faith by the Parties to take
account of the results of any ongoing stability studies; (f) such Product has not been adulterated or misbranded under the Federal Food, Drug, and Cosmetic Act, as amended (the “FFDCA”), and similar provisions of other
Applicable Law; (g) such Product may be introduced into interstate commerce pursuant to the FFDCA and similar provisions of other Applicable Law; and (h) neither Lupin nor any of its Affiliates has been debarred or is subject to debarment
pursuant to Section 306 of the FFDCA or listed on either Excluded List. 
 2.7 Failure or Inability to Supply
Product. 
 (a) In the event that Lupin, at any time during the Term, shall have reason to believe that it
will be unable to supply Salix with the full quantity of Product forecasted to be ordered or actually ordered by Salix in a timely manner and in conformity with the warranty set forth in Section 2.6 (whether by reason of force majeure or
otherwise), Lupin shall, as promptly as possible, notify Salix thereof (and, in any event, shall use commercially reasonable efforts to provide at least [*] ([*]) days’ advance notice thereof to Salix). Promptly thereafter, the Parties shall
meet to discuss how Salix shall obtain such full quantity of conforming Product. Compliance by Lupin with this Section 2.7(a) shall not relieve Lupin of any other obligation or liability under this Agreement, including any obligation or
liability under Section 2.7(b), (c), or (d). 
 (b) If Lupin fails to deliver the full quantity of Product
specified in a Purchase Order by [*] ([*]) days after the required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, 

  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 -12-

 
(i) cancel all or any portion of such Purchase Order, in which event Salix shall have no liability with respect to the portion of such Purchase Order so cancelled, or (ii) accept late
delivery of all or any portion of the Product specified in such Purchase Order. 
 (c) If Lupin fails to deliver
the full quantity of Product specified in a Purchase Order by [*] ([*]) days after the required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, (i) cancel all or
any portion of such Purchase Order, in which event Salix shall have no liability with respect to the portion of such Purchase Order so cancelled, or (ii) accept late delivery of all or any portion of the Product specified in such Purchase
Order, in which event the Purchase Price otherwise payable by Salix with respect to all Product accepted by Salix under such Purchase Order shall be reduced by [*] percent ([*]%). 

(d) If Lupin fails to deliver the full quantity of Product specified in a Purchase Order by [*] ([*]) days after the
required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, (i) accept late delivery of all or any portion of the Product specified in such Purchase Order, in which
event the Purchase Price otherwise payable by Salix with respect to all Product accepted by Salix under such Purchase Order shall be reduced by [*] percent ([*]%) or (ii) provide written notice to Lupin of its intention to qualify a third party
manufacturer for the Product, in which event Lupin shall use its commercially reasonable efforts promptly to assist Salix to qualify such third party manufacturer designated by Salix to Manufacture the Product, and shall promptly grant to such third
party manufacturer, on a royalty-free, non-exclusive basis, such licenses, and provide to such third party manufacturer, at Lupin’s standard time and materials cost, such technical assistance, as such third party manufacturer may require in
order to Manufacture the Product to the then-current Specifications in accordance with the then-current Manufacturing process for the Product, including full technology transfer of the then-current Manufacturing processes for the Product, as well
as, at Salix’s option, such inventories of Lupin-Supplied Materials as are necessary to effect such qualification and technology transfer and enable Salix to obtain an uninterrupted supply of the Product, in all cases solely for use by Salix in
its production of the Product. 
 (e) In the event that Salix determines, within [*] ([*]) days after delivery
thereof by Lupin (or within [*] ([*]) days after discovery of any nonconformity that could not reasonably have been detected by a customary inspection on delivery), that any Product supplied by Lupin does not conform to the warranty set forth in
Section 2.6, Salix shall give Lupin notice thereof (including a sample of such Product, if applicable). Lupin shall undertake appropriate evaluation of such sample and shall notify Salix whether it has confirmed such nonconformity within [*]
([*]) days after receipt of such notice from Salix. If Lupin notifies Salix that it has not confirmed such nonconformity, the Parties shall submit the dispute to an independent testing laboratory or other appropriate expert mutually acceptable to
the Parties (the “Testing Laboratory”) for evaluation. Both Parties shall cooperate with the Testing 

  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

Laboratory’s reasonable requests for assistance in connection with its evaluation hereunder. The findings of the Testing Laboratory shall be binding on the Parties, absent manifest error.
The expenses of the Testing Laboratory shall be borne by Lupin if the testing confirms the nonconformity and otherwise by Salix. If the Testing Laboratory or Lupin confirms that a lot of Product does not conform to the warranty set forth in
Section 2.6, Lupin, at Salix’s option, promptly shall (i) supply Salix with a conforming quantity of Product at Lupin’s expense or (ii) reimburse Salix for the Purchase Price paid by Salix with respect to such nonconforming
Product if already paid. In addition, Lupin promptly shall reimburse Salix for all costs incurred by Salix with respect to such nonconforming Product. Salix shall have the right to offset any such costs against any payments owed by Salix to Lupin
under this Agreement. Lupin immediately shall notify Salix if at any time it discovers that any Product delivered hereunder does not conform to the warranty set forth in Section 2.6. 

(f) For purposes of this Section 2.7, delivery of [*] percent ([*]%) or more of the Product ordered pursuant to any
Purchase Order shall constitute “full delivery.” 
 2.8 Inventory Warehousing. Following delivery by Lupin,
Salix agrees to maintain Product at a facility that is temperature and humidity controlled. Salix agrees to inspect the facility where the Product is held or stored, and keep records of such inspection in accordance with Salix’s standard
operating procedures, which records may be requested by Lupin for cause. 
 2.9 Current Capacity and Scale-Up Plans.

 (a) Lupin represents and warrants to Salix that Lupin’s Capacity as of the Effective Date is as set forth on Schedule
2.9(a) (the “Current Capacity”). 
 (b) Lupin agrees that at all times during the Term it
will not, unless otherwise agreed in writing by Salix, allow its Capacity to be less than the Current Capacity (or any increased capacity, (i) to the extent Lupin has determined in its sole discretion to make it available as of the Launch Date,
or (ii) as subsequently agreed pursuant to any Scale-Up Plans). Without limiting the foregoing sentence, Lupin agrees that it will not at any time during the Term enter into any commitment to sell or otherwise supply the Product to any third
party, whether directly or indirectly and whether at wholesale or retail, that would cause its Capacity to be less than the Current Capacity (or any increased capacity, (i) to the extent Lupin has determined in its sole discretion to make it
available as of the Launch Date, or (ii) as subsequently agreed pursuant to any Scale-Up Plans). 
 (c) In
the event that at any time during the Term Salix contemplates that its annual requirements of Product are likely to exceed the Current Capacity (or any increased Capacity as of such date), Salix shall promptly notify Lupin of that fact and the
Parties shall thereafter discuss in good faith plans to increase Lupin’s Capacity 

  

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

 ARTICLE VII. INDEMNIFICATION 
 7.1 Lupin Indemnification. Lupin
shall indemnify Salix, its Affiliates and its and their respective directors, officers, employees and agents (the “Salix Indemnified Parties”), and defend and hold each of them harmless, from and against any and all claims,
lawsuits, losses, damages, liabilities, penalties, costs and expenses (including reasonable attorneys’ fees and disbursements) (collectively, “Losses”) incurred by any of them in connection with, arising from or occurring as a
result of (a) the breach by Lupin of any of its representations or warranties set forth in this Agreement, (b) Lupin’s material breach of this Agreement, (c) Lupin’s negligence or willful misconduct in the performance of
this Agreement, (d) the storage, release, or disposal of any hazardous or regulated material or any waste by Lupin, and (e) the enforcement by Salix of its rights under this Section 7.1, except, in each case, for those Losses for
which Salix has an obligation to indemnify the Lupin Indemnified Parties pursuant to Section 7.2, as to which Losses each Party shall indemnify the other Party to the extent of its respective liability for such Losses. 

7.2 Salix Indemnification. Salix shall indemnify Lupin, its Affiliates and its and their respective directors, officers, employees
and agents (the “Lupin Indemnified Parties”), and defend and hold each of them harmless, from and against any and all Losses incurred by any of them in connection with, arising from or occurring as a result of (a) the breach by
Salix of any of its representations or warranties set forth in this Agreement, (b) Salix’s material breach of this Agreement, (c) except in respect of any plant, equipment or Manufacturing technology used by Lupin to Manufacture
Product hereunder, any Third Party Claim made by any Person that the Manufacture and supply of Product in accordance with and as contemplated by the terms hereof infringes, misappropriates or otherwise violates the patent, Trademark or other
intellectual property rights of such Person, (d) any Third Party Claim made by any Person relating to or arising out of death, personal injury, or other product liability, related to the marketing, sale, distribution or use of Product and
caused by the negligence of Salix or its subcontractors or agents, including Salix’s manufacturers (other than Lupin or its Affiliates), warehousers or distributors, and (e) the enforcement by Lupin of its rights under this
Section 7.2, except, in each case, for those Losses for which Lupin has an obligation to indemnify the Salix Indemnified Parties pursuant to Section 7.1, as to which Losses each Party shall indemnify the other Party to the extent of its
respective liability for such Losses. 
 7.3 Indemnification Procedure. 

(a) Notice of Claim. The indemnified party (the “Indemnified Party”) shall give the indemnifying
Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of facts upon which such Indemnified Party intends to base a request for indemnification under
Section 7.1 or 7.2, but in no event shall the Indemnifying Party be liable for any Losses 

  
 -30-

 
that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the
nature and amount of such Loss are known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses. 

(b) Third Party Claims. The obligations of an Indemnifying Party under this Article VII with respect to Losses arising from claims
of any third Person that are subject to indemnification as provided for in Section 7.1 or 7.2 (a “Third Party Claim”) shall be governed by and be contingent upon the following additional terms and conditions: 

(i) Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving written
notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be construed as an
acknowledgment that the Indemnifying Party is liable to indemnify any Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified
Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the Indemnifying Party, which shall be
reasonably acceptable to the Indemnified Party. In the event the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the Indemnifying Party all original notices and documents (including
court papers) received by any Indemnified Party in connection with the Third Party Claim. Subject to clause (ii) below, if the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the
Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the Indemnifying Party is
not obligated to indemnify, defend or hold harmless a Salix Indemnified Party or Lupin Indemnified Party, as applicable, from and against the Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and
expenses (including reasonable attorneys’ fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defense of the Third Party Claim with respect to such Salix Indemnified Party or Lupin Indemnified Party, as applicable.

 (ii) Right to Participate in Defense. Without limiting Section 7.3(b)(i), any Indemnified Party shall be
entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnified Party’s own expense
unless (A) the employment thereof has been specifically authorized by the Indemnifying Party in writing, (B) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 7.3(b)(i) (in which
case the Indemnified Party shall control the defense), or (C) the interests of the Indemnified Party and the Indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel
of both parties under Applicable Law, ethical rules or equitable principles. 

  
 -31-

 (iii) Settlement. With respect to any Losses relating solely to the payment of money
damages in connection with a Third Party Claim and that will not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnified Party in any manner, and as to which
the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the Indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise
dispose of such Loss, on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third
Party Claim in accordance with Section 7.3(b)(i), the Indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss; provided that it obtains the prior
written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party shall not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached
without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or
dispose of, any Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). 
 (iv) Cooperation. If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall cooperate in the defense or prosecution thereof and shall furnish such
records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal
business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making employees and agents available on a mutually
convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

 (v) Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and
disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim shall be reimbursed on a calendar quarter basis in arrears by the Indemnifying Party, without prejudice to the Indemnifying Party’s right to
contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party. 

  
 -32-

 7.4 Insurance. 

(a) Each Party shall maintain (i) comprehensive general liability insurance with a combined single limit for bodily
injury and property damage of not less than [*] United States Dollars ($[*]) and (ii) product liability/completed operations coverage with a per claim limit of not less than [*] United States Dollars ($[*]) (collectively, the
“Policies”). If any Policy is written on a claims-made basis, the retroactive date, if any, shall not be later than the date that the certificates of insurance are required to be delivered pursuant to clause (b) of this
Section 7.4. In addition, such coverage shall be continued in full force from such date until the end of the Term of this Agreement and for a period of [*] ([*]) years thereafter and neither Party’s Policies shall be canceled or subject to
a reduction of coverage or any other modification without written notice to the other Party. 
 (b) Each Party
shall furnish certificates of insurance for its Policies to the other Party within thirty (30) days following delivery of the Informational Forecast contemplated by Section 2.2(b). 

7.5 Limitation on Damages. EXCEPT WITH RESPECT TO THE [*] OR INTENTIONAL MISCONDUCT OF A PARTY, NEITHER PARTY SHALL BE LIABLE TO
THE OTHER PARTY FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE; PROVIDED, HOWEVER, THAT
THIS EXCLUSION IS NOT INTENDED TO, NOR SHALL IT, EXCLUDE DAMAGES OWED TO THIRD PARTIES.

rendered in any action or proceeding based thereon. 
 8.8 Audit; Late Payments. 

(a) Each Party shall have the right to have an independent certified public accounting firm of internationally recognized
standing, and reasonably acceptable to the other Party, provided with access by such other Party during normal business hours, and upon reasonable prior written notice, to examine only those records of such other Party (and its Affiliates and
sublicensees) as may be reasonably necessary to determine, with respect to any Calendar Year ending not more than [*] ([*]) [*] prior to the auditing Party’s request, the correctness or completeness of any payment made or statement submitted
under this Agreement. Such examinations may not (i) be conducted more than once in any [*] ([*]) month period (unless a previous audit during such [*] ([*]) month period revealed an underpayment with respect to such period or an incorrect
statement submitted by the audited Party in respect of such period or the audited Party restates or revises such books and records for such period) or (ii) be repeated for any Calendar Year. Results of such audit shall (i) be
(A) limited to information relating to the Product, (B) made available to both Parties in writing, and (C) subject to Article V and (ii) not reveal any specific information of the audited Party to the auditing Party other than
(A) whether the audited Party is in compliance with its payment obligations under this Agreement or whether statements submitted by the audited Party under this Agreement are true and correct, as the case may be, and (B) the amount of any
additional payment owed to the auditing Party or excess payment reimbursable to the audited Party or any correction to statements submitted by the audited Party under this Agreement, as the case may be. Except as provided below, the cost of this
examination shall be borne by the auditing Party, unless the audit reveals a variance of more than five percent (5%) from the reported amounts, in which case the audited Party shall bear the cost of the audit. Unless disputed pursuant to
Section 8.8(b), if such audit concludes that additional payments were owed or that excess payments were made during such period, the audited Party shall pay the additional amounts, with interest from the date originally due as provided in
Section 8.8(c), or the auditing Party shall reimburse such excess payments, with interest from the date of original payment as provided in Section 8.8(c), within sixty (60) days after the date on which such auditor’s written
report is delivered to the Parties.

interest thereon (before and after any judgment) at an annual rate (but with interest accruing on a daily basis) equal to the lesser of (a) the prime rate as reported on the first business day of each month such payment is overdue in The
Wall Street Journal, Eastern Edition, plus [*] ([*]) percentage points, and (b) the maximum rate permitted by Applicable Law. Interest payable under this Section 8.8(c) shall run from the date upon which payment of the relevant
principal sum became due through the date of payment thereof in full together with such interest.

 8.10 Export Control. This Agreement is made subject to any restrictions concerning the export of products or
technical information from the United States or other countries that may be imposed on the Parties from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under
this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the
appropriate agency or other governmental entity in accordance with Applicable Law. 
 8.11 Assignment. Except as
expressly provided herein, neither Party may, without the prior written consent of the other Party, sell, transfer, assign, delegate, pledge, subcontract or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise,
this Agreement or any of its rights or duties hereunder; provided, however, that (a) Salix may, without such consent, assign this Agreement and its rights and obligations hereunder to an Affiliate or to the purchaser or
sublicensee of Salix’s rights in and to the Compound or Product, (b) Lupin may, without such consent, assign this Agreement and its rights and obligations hereunder to one or more Affiliates, and (c) either Party may, without such
consent, assign this Agreement and its rights and obligations hereunder to the purchaser of all or substantially all of its assets or to any successor entity or acquirer in the event of a merger, consolidation or change in control of such Party. Any

	*	Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 -38-

 
Agreement in violation of this Section shall be null and void. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of
and be enforceable by and against the successors and permitted assigns of Salix or Lupin, as the case may be. In the event either Party assigns or delegates its rights or obligations to another Person in accordance with the terms hereof, the
assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement and the assignor or transferor shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this Agreement
from and after the effective date of such assignment. No such assignment or delegation shall relieve the assignor or transferor of any of its obligations hereunder. Notwithstanding the foregoing, Lupin shall have the right, from time to time and
without the necessity of providing notice to or obtaining the consent of Salix, to delegate, assign, or subcontract to any Affiliate, certain of Lupin’s rights or responsibilities under this Agreement. In all cases, Lupin shall remain the
contract Party under this Agreement and shall remain responsible to Salix for the performance of all such obligations under this Agreement. 
 8.12 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a
written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by either Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the
same or any other term or condition of this Agreement on any future occasion. 
 8.13 Severability. If any provision of
this Agreement is held to be illegal, invalid or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision
shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full
force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of
this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties herein.  

8.14 Independent Contractors. The status of the Parties under this Agreement shall be that of independent contractors. Nothing in
this Agreement is intended or shall be deemed to constitute a partnership, agency, employer, employee, or joint venture relationship between the Parties. Neither Party shall have the right to enter into any agreements on behalf of the other Party,
nor shall it represent to any Person that it has any such right or authority. 
 8.15 Construction. Unless the context of
this Agreement otherwise requires: (a) words of any gender include each other gender; (b) words using the singular or plural number also include the plural or singular number, respectively; (c) the terms “hereof,”
“herein,” “hereby” and derivative or similar words refer to this entire Agreement; (d) the

business days are specified. The captions of this Agreement are for convenience of reference only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The

 8.16 Remedies. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth
herein. 
 8.17 Counterparts; Facsimile Execution. This Agreement may be executed in any number of counterparts, each of
which shall be deemed to be an original, and all of which, taken together, shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement (and each amendment, modification and waiver in
respect of it) by facsimile or other electronic transmission shall be as effective as delivery of a manually executed original counterpart of each such instrument.

amendment that constitutes part of the API Supply Agreement.
