 (a) If the production, sale or use of Licensed Products in
the Territory under this Agreement results in any claim by a third party against Salix or a Salix Affiliate for infringement of such third party’s patent or other intellectual property rights, Salix shall promptly notify aaiPharma thereof in
writing, setting forth the facts of such claim in reasonable detail. The parties shall consult with each other in good faith regarding any claim of patent infringement and how it may best be resolved in a manner allowing for continued manufacture
and sale of Licensed Products hereunder. 
  

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

 (b) aaiPharma represents and warrants that (i) during the Term, the manufacture of
Licensed Products by aaiPharma does not violate any third party patent(s), trade secret(s) and/or other intellectual property right(s) in the United States, (ii) as of the Effective Date, any label(s), package insert(s) and any other trade
literature or marketing materials supplied by aaiPharma with regard to the Licensed Product do not violate any third party patent(s), copyright(s), trademark(s), trade secrets and/or other intellectual property rights in the United States, (iii) as
of the Effective Date, the use of the Licensed Trademarks in the United States to market or sell Licensed Products for human use in the United States does not violate any United States trademark(s) and/or other intellectual property rights in the
United States, (iv) as of the Effective Date, the sale and distribution, of Licensed Products in the United States in the ordinary course of business for use as indicated on the package insert will not infringe any valid third party patents relating
to the Licensed Products and their manufacture, (v) as of the Effective Date, no third party licenses, other agreements securing the right to use third party intellectual property, patents, or other proprietary rights are necessary to enable Salix
to sell or distribute the Licensed Products in the United States, except those licensed or granted by aaiPharma herein, and (vi) as of the Effective Date, any labels package inserts or other trade literature supplied by aaiPharma do not infringe any
third party copyrights, trademarks, or other intellectual property rights in the United States (the “Infringement Warranty”). Subject to the provisions of this Section 13.1(b), and in addition to any indemnification obligations under
Section 16.2, aaiPharma shall indemnify and hold harmless Salix, its Affiliates and their respective officers, directors, shareholders, successors and assigns, employees (“Salix Indemnified Parties”) from and against any and all claims,
suits, losses, damages, judgments, costs, fees, and expenses, including, without limitation, reasonable attorney’s fees (collectively, “Losses”) resulting from or arising out of any alleged breach of the Infringement Warranty;
provided that aaiPharma shall not be obligated to so indemnify Salix Indemnified parties pursuant to this Section 13.1(b) to the extent that the alleged infringement arises out of (i) Salix’s breach or non-compliance with any of the
provisions of this Agreement or (ii) the negligence or intentional wrongdoing by any of the Salix Indemnified Parties in connection with one or more acts that gave rise to the suit. Counsel shall be selected by aaiPharma and be acceptable to Salix
which acceptance shall not be unreasonably withheld. A single counsel may simultaneously represent both parties in an action unless counsel advises that a conflict exists between the interests of aaiPharma and Salix with respect to such action such
that it would be inappropriate for aaiPharma and Salix to be represented by the same counsel. If aaiPharma is unable to procure any license from a third party owning or controlling rights that would be infringed or misappropriated by the
manufacture, use, sale, offer for sale of Licensed Products in the United States on commercially reasonable terms, aaiPharma shall so notify Salix and Salix shall discontinue manufacturing, using and selling such Licensed Product; provided
that prior to being required to cease such activities, (i) the parties shall first confer in good faith as promptly as practicable as to whether to alter their approach to the infringing activities with respect to the Licensed Product that would
avoid such infringement without adversely affecting their rights under this Agreement or otherwise adversely affecting the manufacture, use, marketing, sale, or distribution of Licensed Product in the United States, and (ii) the third party owning
(or having the right to license) such technology shall have refused to grant a license to aaiPharma under terms acceptable to aaiPharma and the third party, and (iii) aaiPharma shall have afforded Salix an opportunity to 

  

 14 








 
seek such third party license directly and, within [*] of being given such opportunity, reach agreement on material terms with respect to such
license. 
  
 (c) If as a result of litigation or
settlement with respect to breach of the Infringement Warranty, Salix is required to enter into a license or other agreement requiring it to pay any royalties or make any payment of any kind to enable Salix to continue the manufacture, use,
marketing, distribution, or sale of Licensed Products in the United States, Salix may deduct from the quarterly royalty payment provided in Section 3 the full amount paid by Salix to such third party, until such time as Salix has deducted an
aggregate amount equal to [*] percent ([*]%) of the amount so paid to such third party. If the manufacture, use or sale of Licensed Products infringes, or is likely to infringe, the patent rights of a third party and is
not likely to be resolved in a manner allowing for continued manufacture, use, marketing, distribution, and sale of the Licensed Products in the United States, Salix may terminate the license rights under this Agreement with respect to the United
States, upon written notice to aaiPharma. Notwithstanding the foregoing, nothing in this Section 13.1(c) shall relieve aaiPharma of its indemnification obligations under Section 13.1(b). 
  
 (d) Notwithstanding subsections (a) through (c) above, upon Salix’s exercise of the Assignment Option,
aaiPharma shall have no further rights or obligations with respect to any patent infringement defense or similar or related litigation. 
  
 13.2 Infringement by Third Parties. 
  
 (a) Each party shall promptly notify the other if it is believed that substantial infringement or misappropriation of the Licensed
Trademarks by a third party has occurred or has been threatened, or if it becomes aware of any challenge to the validity or interpretation of the Licensed Trademarks. Salix shall have the first right, but not the obligation, to assume the primary
right and responsibility to take any and all actions seeking to prevent and/or cause the discontinuance of any infringement of the Licensed Trademarks, or defend such challenge. aaiPharma agrees that it will, at Salix’s request and expense,
furnish such reasonable assistance as may be required to assist in preventing or discontinuing any such infringement or defending against such challenge, and shall join Salix as a named party if required by law or otherwise reasonably advisable to
do so. If Salix brings suit under this paragraph: 
  
 (i) Salix shall defend the validity and enforceability of the Licensed Trademarks in any such suit in a commercially reasonable manner; and 
  
 Salix shall be permitted to deduct the out-of-pocket expenses related to the suit and any related settlement from any recovery, lump-sum settlement or royalty payment
made to Salix by the alleged infringer. Any remaining amount reasonably attributable to lost sales of Licensed 
  

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

  

 15 








 Products shall be treated as if it were Net Sales made by Salix and included in the calculation of royalties pursuant to
Section 3.1, with aaiPharma receiving a royalty thereon and Salix retaining the balance. 
  
 (b) If Salix chooses not to act under Section 13.2(a), aaiPharma shall have the right, at aaiPharma’s sole expense, to prevent and/or
cause the discontinuance of any infringement of the Licensed Trademarks or defend any challenge to the validity or interpretation of the Licensed Trademarks. In such event, aaiPharma may, but is not required to, pursue discontinuance of the alleged
infringement or deal with such challenge, or bring suit against such third party. Salix will, at the request and expense of aaiPharma, give reasonable assistance to aaiPharma in the prosecution of any such suit brought by aaiPharma pursuant to this
subsection(b). 
  
 (c) Notwithstanding the
foregoing, upon Salix’s exercise of the Assignment Option, aaiPharma shall have no further right to prosecute or otherwise participate in any litigation regarding the infringement of the Licensed Trademarks by a third party. 
  
 13.3 Participation Right. Notwithstanding the foregoing, Salix shall
be entitled to participate through counsel of its own choosing in any legal action described in 13.1, at Salix’s sole discretion and at its own cost. Notwithstanding the foregoing, until such time, if any, as Salix exercises the Assignment
Option, aaiPharma shall be entitled to participate through counsel of its own choosing in any legal action described in 13.2, at aaiPharma’s sole discretion and at its own cost. 
  
 14. Waiver. It is agreed that no waiver by either party hereto of any breach or default of any of the covenants or agreements herein
set forth shall be deemed a waiver as to any subsequent and/or similar breach or default. 
  
 15. Assignments. This Agreement is binding upon and shall inure to the benefit of each party, their successors and assigns, provided that neither party may assign this Agreement, and aaiPharma may not assign
the ANDA, without the prior written consent of the other, which consent shall not be unreasonably withheld, and further provided that, notwithstanding the foregoing, either party may assign this Agreement and its rights and obligations hereunder,
and aaiPharma may assign the ANDA, without the other party’s consent (a) in connection with the transfer or sale of all or substantially all of its assets or business, its merger, or consolidation with another company, or (b) to any Affiliate;
provided that in the event of the assignment to an Affiliate, the assigning party shall remain jointly and severally liable with the Affiliate for any and all obligations and responsibilities of such assigning party. 
  
 16. Indemnification. 
  
 16.1 By Salix. Salix agrees to indemnify, hold harmless and defend aaiPharma, its Affiliates and their respective
officers, directors, shareholders, employees, successors and assigns (collectively, the “aaiPharma Indemnified Parties”), against any and all Losses asserted by third parties, both government and private, resulting from or arising out of
(i) the sale of Licensed 

  

 16 








 
Products under this Agreement, (ii) Salix’s breach of any of its representations and warranties set forth in Section 19 of this Agreement, or (iii) the
gross negligence or willful misconduct of any of the Salix Indemnified Parties; provided, however, that Salix shall not be required to indemnify, hold harmless and defend any aaiPharma Indemnified Party against any Losses attributable to or arising
out of any aaiPharma Indemnified Party’s (i) negligence or willful misconduct, (ii) breach of this Agreement, or (iii) failure to comply with all applicable laws, rules, and regulations. 
  
 16.2 By aaiPharma. aaiPharma agrees to indemnify, hold harmless and
defend Salix Indemnified Parties against any and all Losses asserted by third parties, both government and private, resulting from any aaiPharma Indemnified Party’s (i) gross negligence or willful misconduct, (ii) breach of any of its
representations and warranties set forth in Section 19 of this Agreement, or (iii) failure to comply with any laws, rules, and regulations; provided, however, that aaiPharma shall not be required to indemnify, hold harmless and defend any Salix
Indemnified Party against any Losses for which Salix assumed responsibility under Section 16.1 or for any Losses attributable to or arising out of any Salix Indemnified Party’s (i) negligence or willful misconduct, (ii) breach of this
Agreement, or (iii) failure to comply with all applicable laws, rules, and regulations. The obligations under this Section 16.2 are in addition to any obligations of aaiPharma under Section 13.1(b). 
  
 16.3 Procedure. If either party is seeking indemnification under
Section 16.1 or 16.2, it shall inform the indemnifying party of the claim or Losses giving rise to the obligation to indemnify pursuant to such section as soon as reasonably practicable after receiving notice of the claim or becoming aware of such
Losses. The indemnifying party shall have the right to assume the defense of any such claim for which it is obligated to indemnify the indemnified party under Section 16.1 or 16.2. The indemnified party shall cooperate with the indemnifying party
(and its insurer) as the indemnifying party may reasonably request, and at the indemnifying party’s sole cost and expense. The indemnified party shall have the right to participate, at its own expense and with counsel of its choice, in the
defense of any claim or suit that has been assumed by the indemnifying party. Neither party shall have the obligation to indemnify the other party in connection with any settlement made without the indemnifying party’s written consent, provided
that the indemnifying party does not unreasonably withhold or delay any such written consent. If the parties cannot agree as to the application of Sections 16.1 or 16.2 to any claim or losses, the parties may conduct separate defenses of such
claims, with each party retaining the right to claim indemnification from the other in accordance with Section 16.1 or 16.2 upon resolution of the underlying claim.
