have been terminated under Sections 14.4 or 14.5; 
  

	4.1.2	in respect of the Sanvar Product for the Sanvar Royalty Term; 

  

	 	(a)	a unit royalty, calculated as an amount per Unit of Sanvar Product manufactured and supplied to Salix by an Approved Manufacturer (the “Unit Royalty”) during the

 4.2 Adjustment of Sanvar Product Royalty. The Sanvar Product Royalty and the sums payable in respect thereof shall be adjusted as follows;

 4.2.1 it is acknowledged and agreed that where Salix obtains supply of the Sanvar Product and API from an Approved Manufacturer under the terms of a
Manufacturing Agreement agreed with Debiovision under Section 9, in respect of each Unit of Sanvar Product the Unit Royalty (under Section 4.1.2(a)) plus the Net Sales Royalty (under Section 4.1.2(b)) plus the Cost of Goods
(“the Unit Cost”) averaged over any Quarter shall not, for the Sanvar Royalty Term exceed US$[*] ([*] dollars) (“the Cap”) provided that for the purpose of calculating the Unit Cost and the Cap, the following shall
apply: 
  

	 	(a)	the Cost of Goods element shall for the purposes of indexation under this Section 4.2.1 only, be deemed as at the Effective Date to be US$[*] ([*] US dollars) per Unit and such
deemed Cost of Goods shall with effect from the Effective Date be indexed and shall be increased (if appropriate) on 1 January in each year (commencing on 1 January 2008) by the percentage increase (if any) in the Producer Price Index
Pharmaceutical Preparations Mfg (Series ID pcu 325412325412) as published by the US Department of Labor, Bureau of Labor Statistics or any successor index thereto during the preceding twelve months and the Cap shall be increased accordingly to
reflect any change in such index as applied to such deemed Cost of Goods element; and 

  

	 	(b)	where the Approved Manufacturer prices and invoices in a currency other than US$, the Cost of Goods in respect of each batch of Products shall be calculated in US$ by reference to
the exchange rate applicable on the date of payment by Salix of the Approved Manufacturer’s invoice. If such exchange rate shall vary from the exchange rate applicable as at the Effective Date (which for invoicing in Swiss Francs is set at 1
CHF/Swiss Franc: US$0.78; and for invoicing in Euro is set at 1 Euro: US$1.22) in a manner which shall increase the US$ cost; 

  

	 	(i)	by less than [*]% variation, the actual US$ price paid by Salix shall remain the Cost of Goods in calculating the Unit Cost; 

  

	 	(ii)	by greater than [*]% variation, [*]% of the additional sum paid by Salix by reason of the exchange rate variation in excess of the [*]% variation, shall be deducted from the Cost of
Goods in calculating the Unit Cost. 

 If the Unit Cost (calculated in accordance with the above) shall exceed the Cap (adjusted as above) in
any Quarter the Unit Royalty under Section 4.1.2(a) shall be adjusted and reduced by such sum as shall equal the excess over the Cap, for such Quarter, with any credit being applied to payments due in respect of Unit Royalty in the subsequent
Quarter. 
  

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

  

 19 

 4.2.2 at the end of each Quarter on delivery of the Net Sales Report under Section 4.7, Salix shall calculate the
percentage difference between Sales and Net Sales in such Quarter (that is Deductions represented as a percentage of Sales) and such percentage difference shall be deducted from the Unit Royalty actually paid in the preceding Quarter in respect of
each Unit of Product with any credit being applied to payments in respect of Unit Royalty due in the subsequent Quarter. 
 4.3 Minimum Payments.
Within sixty (60) days of the end of each year (being a period of twelve months from the Launch Date, or any anniversary of the Launch Date (“Year”)) during the Sanvar Royalty Term, Salix shall make a balancing payment (if any)
such that the total amount of Royalty paid to Debiovision for such Year under Section 4.1.2 shall not be less than the sums set out below in respect of such Year (the “Minimum Payments”); 
  

				
	 Year Commencing on Launch Date
	  	 Amount of
 Minimum Payment

	Year 1	  	 	[*]
	Year 2	  	US$	[*]
	Year 3	  	US$	[*]
	Year 4	  	US$	[*]
	Each subsequent Year to expiry of the Sanvar Royalty Term	  	US$	[*]

 Provided that such obligation to effect a Minimum Payment shall cease with effect from the date of introduction on
to the market in the Territory of a Generic in respect of the Sanvar Product (save for a Salix Generic) and shall be payable (if any) pro rata in respect of any part of a Year in which such a Generic may be introduced. 
 4.4 No deduction of costs. Save as specified in the definition of Net Sales and Deductions or as provided in Section 4.2.1 no costs incurred by Salix in the
development, manufacture or Commercialization of the Products shall be deducted from any Royalties payable to Debiovision hereunder. 
 4.5 Sales.
Salix shall use all reasonable endeavours to price the Sanvar Product in such manner as shall maximise Sales of the Sanvar Product in the Territory. Salix shall not commercialize any Product in conjunction with any other products in the Territory as

for delivery of Sanvar Product, Salix shall pay to Debiovision the Unit Royalty payable in respect of each Unit so invoiced. Each Royalty payment shall be accompanied by a copy of the Approved Manufacturer’s invoice and a written report (the
“Unit Royalty Report”) prepared by Salix which shall set forth, for the period covered by the Unit Royalty Report, (i) the number of Units of Sanvar Products so invoiced by such Manufacturer; (ii) the calculation of the
Royalty under Section 4.1.2 that is being paid to Debiovision; and (iii) any adjustment applied in accordance with Section 4.2 in respect of the preceding Quarter.

such audit. The results of such audit shall promptly be made available to Salix. If the review indicates a deficiency or reflects that the payments to Debiovision under Section 4 should have been made earlier by Salix, then, as the case may be,
such payment shall be promptly remitted to Debiovision, together with interest calculated in the manner provided in Section 5.7. If the review indicates any overpayment or early payment Debiovision shall credit the same against subsequent
payments. Where the review reveals a discrepancy in the payments due to Debiovision of in excess of [*] per cent ([*]%) of the payments due for such calendar year, Salix shall reimburse Debiovision all of the costs of such audit. 
 5.4 Currency and Method of Payment. All payments to be made pursuant to this Agreement shall be made by Salix to Debiovision in US Dollars (US$)
pursuant to directions given by Debiovision to Salix in writing from time to time, during the relevant Royalty Term.

Section 4 shall not be subject to U.S. Withholding. If, at any time, regulations require that any taxes, duties, charges or levies be withheld from these payments, Salix shall inform Debiovision thereof, whereupon the Parties shall meet and
determine the manner in which such withholding shall be dealt with between the Parties. 
 5.7 Interest. Any payment due hereunder which is not paid
on the date such payment is due in accordance with the provisions set forth in Section 4 shall bear interest at the Prime Rate plus three percent (3%) per annum, calculated on the number of days such payment is delinquent.

the other, either expressly or by implication, under any patent rights, information and know-how owned or controlled by that Party, except as specifically set out in this Agreement.

competent jurisdiction or by a legally enforceable directive of any governmental body, such section or portion thereof shall be validly reformed so as to approximate the intent of the Parties as nearly as possible and, if un-reformable, shall be

 17.11 Counterparts and Headings. The Agreement may be executed in counterparts, each of which shall be deemed to
be an original and both together shall be deemed to be one and the same agreement. The division of this Agreement into Sections, Subsections and Schedules and the insertion of headings and a table of contents are for convenience of reference only
and shall not affect the construction or interpretation of this Agreement. The Section, Subsection and Schedule headings in this Agreement are not intended to be full or precise descriptions of the text to which they refer and such headings and the
table of contents are not to be considered part of this Agreement. All uses of the words “hereto”, “herein”, “hereof”, “hereby” and “hereunder” and similar expressions refer to this Agreement and not
to any particular Section, Subsection or other portion of it. Unless something in the subject matter or context is inconsistent therewith, references herein to a Section, Subsection or Schedule refer to the applicable Section, Subsection or Schedule
of this Agreement. 
 17.12 Language. The Parties acknowledge that it is their express wish that this Agreement and all related documents be prepared
in English. If there is a foreign language translation of this Agreement, the English version shall be the governing language. 
 17.13 Publicity.
Should a Party be required by law or any securities exchange or regulatory or governmental body to which that Party is subject wherever situated, and whether or not such requirement has the force of law to make a public disclosure or announcement
concerning the transaction, the terms hereof or any ancillary matter about the Agreement, then the Party so required may do so; provided, however, that it gives as much in advance notice as is practical or possible to the other Party. Otherwise,
neither Party shall issue any press release or other public disclosure about this Agreement or its terms without the prior written consent of the other Party. Where a request is made by a Party to this Agreement, the Parties shall undertake every
reasonable effort in good faith to agree to the form of a press release or other public statement and shall not depart from the terms thereof without the prior written consent of the other Party. 
 17.14 Entire Agreement. The terms and provisions contained in this Agreement and the attached Schedules constitute the entire agreement between the Parties and

2005, between the Parties shall continue in accordance with its terms in respect of any breach thereof occurring prior to the Effective Date. No agreement or understanding varying or extending this Agreement shall be binding upon either Party
hereto, unless in writing, which specifically refers to the agreement, signed by duly authorized officers or representatives of the respective Parties and the provisions of the agreement not specifically amended thereby shall remain in full force
and effect. 
 17.15 Amendment and Waiver. No modification of or amendment to this Agreement shall be valid or binding unless set forth in writing and
duly executed by both Parties and no waiver of any breach of any term or provision of this Agreement shall be effective or binding unless made in writing and signed by the Party purporting to give the same and, unless otherwise provided, shall be
limited to the specific breach waived. No failure on the part of either Party to exercise, 
  

 42 

 and no delay in exercising, any right under this Agreement shall operate as a waiver of such right. No single or partial
exercise of any such right shall preclude any other or further exercise of any such right or the exercise of any other right. 
 17.16 Equitable
Relief. A material breach by either Party will cause irreparable damage and the non-breaching Party will not be adequately compensated by monetary damages. In the event of a breach, or threatened breach, the non-breaching Party shall be entitled
to obtain equitable relief, whether preliminary or permanent, without the need to show irreparable harm or the inadequacy of monetary damages as a remedy. Nothing in this Section is intended, or shall be construed, to limit the Parties’ rights
to equitable relief or any other remedy for a breach of any provision of this Agreement. 
 IN WITNESS WHEREOF, the
Parties have executed this Agreement in duplicate on the Effective Date.
