|[*] | Confidential treatment requested.
|--- | ---------------------------------

28



---

(iii) on the [*] US$[*] in the same calendar year (i.e., >US$[*]
and < US$[*]): [*]%; and

(iv) above US$[*] in the same calendar year: [*]%.

To illustrate by way of example, if Net Sales in a calendar year were US$[*], the Royalties would be calculated as follows: ([*] x US$[*]) + ([*] x
US$[*]) + ([*] x US$[*]) + ([*] x US$[*]), or US$[*].

(b) Royalty Term.

(i) The Royalties payable under Section 4.5(a) shall be payable by Salix in each country in the Salix Territory
during the Royalty Term.

(ii) Following the expiration of the Royalty Term in respect of a Lumacan Product in
a country in the Salix Territory, the license grants to Salix in Section 2.1 in respect of such Lumacan Product shall, except as otherwise provided by Section 4.5(c), become fully paid-up, perpetual and irrevocable with respect to such
country and the Net Sales of Lumacan Products in such country shall be excluded from the Royalty calculations and calculations of milestone thresholds in this Article 4.

(c) Continuing Royalties. Following the expiration of the Royalty Term in respect of a Lumacan Product in a country
in the Salix Territory, Salix shall, as consideration for its continued right to use the Licensed Trademarks and Licensed Technical Information for such Lumacan Product, pay royalties (Continuing Royalties) to Photocure in respect
of Net Sales by Salix and its Affiliates and Sublicensees at the rate of [*] percent ([*]%) for as long as Salix or its Affiliates or Sublicensees Commercialize such Lumacan Product in such country. Prior to such expiration of the Royalty Term, the
Parties acknowledge and agree that the Continuing Royalties for which provision is made in this Section 4.5(c) are included in the Royalties payable under Section 4.5(a).

(d) Minimum Royalty. If the aggregate Royalties paid or payable prior to the [*] anniversary of the first MAA
Approval of the Lumacan Product in the Salix Territory are less than US$[*], then Salix shall pay Photocure the amount of any shortfall within [*] ([*]) days following such date.

(e) Adjustment of Royalties.

(i) If during the Royalty Term for a country in the Salix Territory, no Valid Exclusivity Rights exist for a particular
Lumacan Product in the country or aggregate commercial sales of a particular Lumacan Product in such country decline (based on Salixs or its Sublicensees internal sales data) on a Quarter-by-Quarter basis for [*] or more consecutive
Quarters following the initiation of commercial sales (by a person other than Salix or its Affiliates or Sublicensees) of a generic version of such Lumacan Product by [*] percent







|[*] | Confidential treatment requested.
|--- | ---------------------------------

29



---

([*]%) or more, then the Royalties payable for Net Sales in respect of such Lumacan Product in such country thereafter during the Royalty Term shall be reduced by [*] percent ([*]%).

(ii) To account for any reduction of Royalties for country made pursuant to this Section 4.5(e),
the royalty rates under Section 4.5(a) shall apply for such country, but the amount of Net Sales in respect of such Lumacan Product in such country for the applicable period shall be reduced by [*] percent ([*]%) before adding such reduced Net
Sales to the Net Sales for the applicable period in all other countries in the Salix Territory where Lumacan Products were sold in such period.

(f) Acknowledgement. Salix acknowledges that (i) the Licensed Technical Information is secret and substantial and without access to the Licensed Technical Information Salix would not be able
to obtain and maintain MAA Approvals or other Regulatory Approvals in the Salix Territory, (ii) access to the Licensed Technical Information is expected to provide Salix with a competitive advantage in the marketplace beyond the exclusivity
afforded by the Licensed Patents or other Valid Exclusivity Rights, and (iii) the Royalties, Continuing Royalties and other amounts payable to Photocure under this Article 4 are, in part, intended to compensate Photocure for such exclusivity
and such competitive advantage. The Parties agree that the payment obligations contemplated by this Article 4 reflect an efficient and reasonable blended allocation of the values provided by Photocure to Salix.

4.6 Royalty and Sublicense Revenue Reports; Payments.

(a) Within [*] ([*]) days after the first day of each Quarter following the First Commercial Sale of a Lumacan Product in
a country in the Salix Territory, Salix shall submit to Photocure a written report with respect to the preceding Quarter (the Royalty and Sublicense Revenue Report) stating: (i) the gross sales, the number of units and Net
Sales of Lumacan Products sold by Salix and any Sublicensee during the Quarter just ended for each country in which sales were made; (ii) the date of any First Commercial Sale of any Lumacan Product in a country in the Salix Territory during
the Quarter just ended; (iii) the amount of any Sublicense Revenue received by Salix during the preceding Quarter, (iv) the currency exchange rates used in determining the Royalties, Continuing Royalties and other amounts payable under
Sections 4.4 and 4.5; and (iv) a calculation of the amounts due to Photocure pursuant to Sections 4.4 and 4.5 in respect of the Quarter just ended, making reference to the specific deductions taken in accordance with the definition of Net Sales
in Section 1.70 and the definition of Sublicense Revenue in Section 1.104. Concurrent with the submission of a Royalty and Sublicense Revenue Report for each such Quarter, Salix shall pay Photocure all Royalties, Continuing Royalties and
other amounts due under Sections 4.4 and 4.5 in respect of the Quarter just ended.

(b) With respect to sales
of the Lumacan Products or Sublicense Revenue booked in currencies other than United States dollars, Net Sales or Sublicense Revenue, as the case may be, during a Quarter shall be calculated based on the average of the final daily published currency
exchange rate in the United States during such Quarter. Each such final







|[*] | Confidential treatment requested.

published exchange rate shall be obtained from: http://markets.ft.com/ft/markets/researchArchive.asp or, if not so available, as otherwise agreed by the Parties.

(c) Salix shall provide such [*] reports of sales (units and value) of Lumacan Products by it, its Affiliates and its

withheld or collected by Salix or its Sublicensees under the Applicable Law of any country on amounts owing from Salix to Photocure hereunder to the extent Salix or its Sublicensees pay such withholding taxes to the appropriate governmental
authority on behalf of Photocure. Salix shall promptly deliver to Photocure proof of payment of such taxes together with copies of all communications from or with such governmental authority with respect thereto. All payments to Photocure under this
Agreement shall be made from the United States.

(c) Late Payments. Any payment due under this Article 4
that is not paid by the applicable due date and is not the subject of good faith dispute between the Parties shall accrue interest, which must be paid by Salix with the payment obligation to Photocure, calculated on a daily basis at a per annum rate
equal to the one month EURIBOR rate per annum as of the date such payment was first owed plus [*] percent ([*]%) per annum, determined in the basis of a three hundred sixty-five (365) day year, or the maximum amount permitted by Applicable Law,
if less, from the date first owed until paid.

(d) Books and Records. Salix shall keep full and true
books of account and other records pertaining to all Net Sales and Sublicense Revenues for at least three years after the year in which such sales or revenues occurred and in sufficient detail so that the Royalties, Continuing Royalties and other
amounts payable to Photocure pursuant to Sections 4.4 and 4.5 can be properly ascertained.

(e) Audit
Rights. No more often than [*] each [*], upon reasonable notice by Photocure, Salix shall permit an independent certified public accountant selected by Photocure to have access, during ordinary business hours, to such books and records as may be
necessary to determine the correctness of any report or payment (including Royalties, Continuing Royalties and other amounts payable to Photocure pursuant to Sections 4.4 and 4.5) made or owed under this Agreement. [*] shall be responsible for
expenses for such independent certified public accountant selected, except that [*] shall reimburse [*] for such expenses, not to exceed

period (so long as the amount actually owed by Salix to Photocure for such period is at least US$[*]) or there is a deficiency amount of more than US$[*]. All such audits made by Photocure hereunder shall be made no later than [*] ([*]) years after
the date such report or payment was due.

4.8 Sublicenses; No Duplication.

(a) Except as otherwise provided in Sections 4.4 and 4.5, Salix shall have no obligation to Photocure or its Affiliates to
share any fees, milestone payments, royalties, financial consideration or other consideration received by Salix and its Affiliates from any sublicense of their rights hereunder.

(b) For the avoidance of doubt, it is the intent of the Parties that no sales of Lumacan Products should give rise both to
Sublicense Revenue that is required to be shared by Salix with Photocure pursuant to Section 4.4 and to Royalties or Continuing Royalties pursuant to Section 4.5. The Parties agree to negotiate in good faith appropriate terms in respect of
any specific circumstance that might otherwise give rise to a result excluded by the preceding sentence to avoid the result so excluded.

of a Licensed Patent and thereafter make payments or take other actions in respect of the Licensed Patent as contemplated by the preceding sentence, then Photocure shall at any time thereafter,
promptly upon Salixs request and expense, execute all such documents and take all such other actions as may be required to transfer and assign the relevant Licensed Patent to Salix. In connection with any such transfer or assignment of a
Licensed Patent to Salix, Salix, shall, and hereby does, grant to Photocure a non-exclusive, nontransferable and sublicensable (in connection only with the development, manufacture or commercialization of HAL Products), fully paid-up and irrevocable
license to practice the inventions covered by such Licensed Patent in the country or countries where the Licensed Patent is effective to the full end of the term or terms for which the Licensed Patent issues. Any license rights granted by Salix to
Photocure pursuant to the preceding sentence shall constitute and be included in Licensed IP and as such shall, without limitation, be subject to Article 2.1, including the exclusive nature of the licenses set forth therein as they relate to
Licensed IP. The provisions of this clause (ii) shall apply to In-Licensed Patents only to the extent (A) Photocure prosecutes such Patents; and (B) Photocure is permitted to take the actions contemplated by this clause (ii) by
its contractual obligations to Third Parties as they exist on the Effective Date.

to initiate or continue prosecution (including validation) and (B) the scope of, issuance of, rejection of, an interference involving, or an opposition to any such Joint Patent application or resulting Joint Patent) such that Photocure has
reasonable time to review and comment upon any documents intended for submission to any patent office; (ii) furnish to Photocure a copy of any such Joint Patent application and copies of documents relevant to such prosecution and maintenance,
including copies of correspondence with any patent office, foreign associates and outside counsel, such that Photocure has reasonable time to review and comment upon any documents (including draft patent applications) intended for submission to any
patent office; (iii) in respect only of Joint Patents claiming the Manufacture of the HAL Active Ingredient or Lumacan Products, the Development of the HAL Active Ingredient or Lumacan Products in the Field, or the Commercialization of Lumacan
Products in the Field or methods of using HAL Active Ingredient in the Field or dosing regimens for HAL Active Ingredient for use in the Field, reasonably consider and to the extent deemed appropriate by Salix in its reasonable judgment, incorporate
the comments of Photocure on any such documents filed with any patent office; and (iv) in respect of Joint Patents other than those addressed by clause (iii), either incorporate the comments of Photocure on any such documents filed with any
patent office in such documents or, in the absence of mutual agreement as to the incorporation or non-incorporation of any such comment, defer filing of such documents, provided, that in no event shall Salix be prevented by this clause
(iv) from making any filing or taking any other action required in order to prevent a Joint Patent from going abandoned or lapsing. Salix shall provide Photocure with the status of such Joint Patents no less frequently than once per every
semi-annual calendar period. Salix shall make reasonable efforts not to take any action in the prosecution of any Joint Patent that could reasonably be expected to affect adversely any other Joint Patent or any Licensed Patent

period to Salix, to make such payment or take such action, and Salix shall reasonably cooperate with Photocure in connection with such maintenance activities. The Parties shall share equally all costs reasonably incurred in connection with the
preparation, prosecution and maintenance of any Joint Patents; provided, however, that either Party may at any time renounce and assign to the other Party any and all right, title and interest of such assigning Party in a Joint Patent and
shall thereafter have no responsibility in respect of costs in respect of the preparation, prosecution or maintenance of such Joint Patent. Any dispute regarding the prosecution and maintenance activities with respect to the Joint Patents shall be
discussed by patent counsel for each Party, who shall use their good faith efforts to mutually agree upon the proper course of action to resolve such dispute. If any dispute is not resolved by the patent counsel for each Party, then the dispute
shall be resolved in accordance with the dispute resolution procedures set forth in Section 15.12.

infringing activities. Any prosecution of any such infringement shall be conducted under the joint control of both Parties with each Party entitled to retain its own counsel for such purpose.

(iii) For all Licensed Patents and for all Joint Patents not described by Section 9.4(b)(ii), Photocure shall have
the sole right, but not the obligation, to initiate and control the prosecution of such infringement or to grant the infringing Third Party adequate rights and licenses to continue such otherwise infringing activities.

(iv) Joint consent of Photocure and Salix is not required for a settlement or consent judgment or other voluntary final
disposition of a suit or proceeding under this Section 9.4(b) that relates to any Licensed Patent or Joint Patent, except that if settlement is reasonably likely to adversely affect the Lumacan Product in the Salix Territory or the validity or
enforceability of a corresponding Licensed Patent in the Salix Territory, then the joint consent of Photocure and Salix is required and such consent shall not be unreasonably withheld or delayed.

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 Licensed Patents or the
intellectual property rights of such non-controlling Party and (ii) the controlling Party shall not be entitled to settle any such 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.

(c)
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 9.5, at the requesting Partys expense, including

---

to or relies on Regulatory Documentation submitted by either Party to any Regulatory Authority, whether or not such a filing may be in violation of any Valid Exclusivity Right or infringe the
Licensed Patents or Joint Patents, (ii) receives any notice of certification regarding such Patents pursuant to the Hatch-Waxman Act claiming that any such Patents are invalid or unenforceable or claiming that the any such Patents will not be
infringed by the manufacture, use, marketing or sale of a product for which an ANDA is filed, or (iii) receives any equivalent or similar certification or notice in any other jurisdiction, it shall notify the other Party in writing, identifying
the alleged applicant or potential applicant and furnishing the information upon which such determination is based, and provide the other Party a copy of any such notice of certification within [*] ([*]) days of receipt and the Parties rights
and obligations with respect to any legal action as a result of such certification shall be as set forth in Section 9.4.

To the extent
required by Applicable Law, Salix shall take all actions as may be required by it to maintain with the applicable Regulatory Authorities correct and complete listings of applicable Licensed Patents and Joint Patents for Lumacan Products, including
all Orange Book listings required under the Hatch-Waxman Act.

Licensed Patents and Joint Patents, each Party shall mark, and have its licensees (or, in the case of Salix, Sublicensees) mark, all patented Lumacan Products they sell or distribute pursuant to this Agreement in accordance with the Applicable Law
in the country or countries of manufacture or sale thereof.

9.8 Additional Licensees under the Licensed Patents. Salix
acknowledges that Photocure has granted, and may in the future grant, Third Parties rights under the Licensed Patents. Photocure represents that none of such rights so licensed include the right to Commercialize Lumacan Products in the Field in the
Salix Territory. Salix acknowledges that such other rights and the prior approval of new drug applications or other marketing authorizations may restrict the ability to obtain further patent term extensions and similar Valid Exclusivity Rights of
any Licensed Patents in the Salix Territory. Moreover, Salix acknowledges that such Third Parties were also granted the right to enforce one or more of the Licensed Patents against Third Parties that infringe the Licensed Patents by activities
relating to Other Products or other pharmaceutical products containing esters of [*] claimed under the Licensed Patents.

9.9
Exception for Patents Licensed from [*]. No rights or obligations of the Parties in Sections 9.3, 9.4 or 9.6 shall apply with respect to any Patents owned or Controlled by [*], which Patents, to the extent included in the Licensed Patents,
are licensed to Salix under Section 2.1.

Salix) for paying all such royalties to the relevant Third Parties.

(d) [*] Patents. The
provisions of this Section 9.10 shall not apply in respect of any license of [*] Patents, but any such license shall instead be governed by the provisions of Section 9.11.

Third Party (collectively, Losses) arising out of any claim, action, lawsuit, or other proceeding (collectively, Claims) against any Photocure Indemnitee by
a Third Party to the extent resulting directly or indirectly from:

(a) the negligence, recklessness or willful
misconduct of Salix or its Affiliates, or their respective directors, officers, employees or agents in performing any activities in connection with this Agreement;

(b) any breach by Salix of any representation, warranty, covenant, undertaking or other term contained in this Agreement;
and

(c) the Manufacture, Development or Commercialization of Lumacan Products for use and sale in the Salix
Territory by or on behalf of Salix or its Sublicensees; provided, however, Salix shall have no indemnification obligation with respect to Photocure or any Photocure Indemnitees with respect to the use of any of the Licensed Trademarks in accordance
with the terms herein;

except, in each case ((a), (b) and (c)), for those Losses for which Photocure has an obligation to indemnify
Salix pursuant to Section 13.2 hereof, as to which Losses each Party shall indemnify the other to the extent of their respective responsibility for the Losses;

13.2 Indemnification of Salix by Photocure. Photocure, at its own cost and expense, shall defend Salix and Salixs Affiliates, and the directors, officers, employees and agents of Salix and

has an obligation to indemnify Photocure pursuant to Section 13.1 hereof, as to which Losses each Party shall indemnify the other to the extent of their respective responsibility for the Losses.

13.3 Indemnification Procedure.

(a) Notice. An Indemnitee shall promptly notify the indemnifying Party (the Indemnitor) in writing of any Claim in respect of which the Indemnitee intends to seek such
indemnification. No delay on the part of the Indemnitee in notifying the Indemnitor



72



---

shall relieve the Indemnitor from any obligation hereunder unless (and then only to the extent that) the Indemnitor is prejudiced thereby.

(b) Control of Proceedings. The Indemnitor shall have the right, exercisable by notice to the Indemnitee within [*]
([*]) business days of receipt of notice from the Indemnitee of the commencement of or assertion of any Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Claim (including the
right to settle the claim solely for monetary consideration) with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee. During such time as the Indemnitor is controlling the defense of such Claim, the Indemnitee shall
cooperate, and cause its Affiliates, agents, licensees and sublicensees (and in the case of Salix, its Sublicensees) to cooperate upon request of the Indemnitor in the defense or prosecution of the Claim, including by furnishing such records,
information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnitor. If the Indemnitor does not notify the Indemnitee of the Indemnitors intent to defend
any Claim within [*] ([*]) business days after notice thereof, the Indemnitee may undertake the defense thereof with counsel of its choice upon notice to the Indemnitor and at the Indemnitors reasonable expense (including reasonable,
out-of-pocket attorneys fees and costs and expenses of enforcement or defense). The Indemnitor or the Indemnitee, as the case may be, shall have the right to join in (including the right to conduct discovery, interview and examine witnesses
and participate in all settlement conferences), but not control, at its own expense, the defense of any Claim that the other Party is defending as provided in this Agreement.

(c) Settlement. The Indemnitor shall obtain the prior consent of any Indemnitee as to any settlement that would
materially diminish or materially adversely affect the scope, exclusivity or duration of any Patents licensed under this Agreement, would require any payment by such Indemnitee, would require an admission of legal wrongdoing in any way on the part
of an Indemnitee or would effect an amendment of this Agreement. In no event may an Indemnitee settle or compromise any Claim for which it intends to seek indemnification from the Indemnitor hereunder without the prior consent of the Indemnitor, or
the indemnification provided under such this Article 13 as to such Claim shall be null and void.

(d)
Exclusive Remedies. Except as otherwise expressly provided under this Agreement, the rights and remedies provided pursuant to this Article 13 are the sole and exclusive remedies of the Parties hereto with respect to the Losses subject to
indemnification under this Article 13. The provisions of this Section 13.3(d) are without prejudice, and are subject, to any terms that may be agreed between the Parties or between any Party and a Third Party in respect of the supply of HAL
Active Ingredient or Lumacan Product, including the provisions of Article 8 and any agreement contemplated thereby.

13.4
Insurance. Each Party shall maintain adequate liability insurance coverage or adequately plan through self-insurance for its liabilities associated with its activities and obligations under this Agreement in such amounts and on such terms as

(f) Assistance. Salix shall, and, subject to Section 14.9, shall cause its Sublicensees to, provide Photocure,
at its request and expense, with such assistance as is reasonably necessary to effectuate a smooth and orderly transition of any Development and Commercialization of Lumacan Products in the Salix Territory (including any ongoing clinical studies or

notice, providedthat at Photocures request, Salix shall promptly provide to Photocure copies of each such Third Party contract for purposes of Photocures determining whether to direct Salix to halt sales of Lumacan Products
pursuant to the foregoing clause (ii). If either such event occurs prior to the sale of all of Salixs inventories and work-in-process of Lumacan Products and the performance by Salix of its obligations under such Third Party contracts, then

any such Third Party contracts.

agreements entered into by Salix or any of its Affiliates with a Sublicensee pursuant to this Agreement shall survive the termination of this Agreement (other than pursuant to 14.3 or 14.5), except to the extent that any such Sublicensee under any
such sublicense agreement is in material breach of this Agreement or such sublicense agreement or Photocure elects to grant such Sublicensee a direct license of the sublicensed rights on the same terms applicable to Salix under this License

15.5 Severability. In the event that any provision of this Agreement shall be found in any jurisdiction to be in violation of
public policy or illegal or unenforceable in law or equity, such finding shall not invalidate any other provision of this Agreement in that jurisdiction. If any provision hereof should be held invalid, illegal or unenforceable in any respect in any
jurisdictions then, to the fullest extent permitted by Applicable Law:

(a) all other provisions hereof shall
remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible;

(b) such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such

(c) the Parties shall promptly negotiate in good faith a replacement
provision to carry out the intention of the invalid, illegal or unenforceable provision to the fullest extent permitted by Applicable Law.

To
the extent permitted by Applicable Law, each Party hereby waives any provision of Applicable Law that would render any provision hereof prohibited or unenforceable in any aspect.

agreement reached between the Parties hereto with respect to the transactions contemplated hereby. This Agreement replaces and supersedes any and all previous agreements and understandings between the Parties regarding the subject matter hereof,

discharge shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties. The failure of either Party hereto to enforce at any time, or for any period of time, any provision of this Agreement

all licenses granted hereunder by such first Party with respect to its technology and any information, materials and inventions with respect thereto. Any purported assignment or transfer in violation of this subsection (a) shall be void ab

SALIX PHARMACEUTICALS
ACQUIRES LUMACAN FROM PHOTOCURE

RALEIGH, NC, October 20, 2010 - Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today
announced that the Company has acquired rights to Lumacan from Photocure (OSE: PHO), a Norwegian specialty pharmaceutical company. Lumacan is a novel agent designed to assist in the detection of precancerous and cancerous lesions in the colon.
Salix and Photocure have entered into an agreement under which the two companies will collaborate in the development and commercialization of Lumacan. Salix now has an exclusive worldwide license to Lumacan, excluding the Nordic region.

Carolyn Logan, President and CEO, Salix Pharmaceuticals, stated, After further development and, if approved by the FDA, Lumacan has the potential
to significantly improve the earlier detection and diagnosis of colon cancer, with the possibility to innovate the way in which colorectal cancer screening is conducted today. We believe this groundbreaking agent could serve a strategic role in
expanding our current bowel cleansing business and advancing our mission to provide healthcare providers with the most effective solutions in gastrointestinal disease.

Lumacan is a novel agent intended for prescription use in colon cancer screening and diagnosis. Lumacan is based on the accumulation of a photosensitizer in the target cells that upon illumination
generate fluorescence and as a result become easily identified. Lumacan contains hexamiolevulinate. Hexamiolevulinate is marketed in Europe for the detection of bladder cancer

Colon cancer screening is conducted through the visual examination of the colon by means of standard white-light colonoscopy. However, the limitations of standard colonoscopy to detect
lesions, particularly flat lesions, contribute to the need for agents designed to assist in the earlier detection of difficult-to-identify pre-cancerous and cancerous lesions, especially in high-risk patients, stated Bill Forbes,
Executive Vice President, Research and Development and Chief Development Officer, Salix. Early stage research with Lumacan has demonstrated that administration via an enema formulation using blue-light colonoscopy identified
approximately 65% more lesions compared to standard, or white-light, colonoscopy. Our hope is that the development of an easy-to-use, well-tolerated oral formulation of Lumacan, used in conjunction with standard colonoscopy, will provide
an innovative approach to assist in the removal of additional high risk lesions that otherwise could go undetected using the current standard colonoscopy procedures. We believe the improved detection and diagnostic capabilities of Lumacan,
especially in targeted high-risk and follow-up patients, has the potential to save lives.

Patents for Lumacan provide intellectual
property protection to 2019 and pending applications have the potential to extend protection to 2030. Upon marketing approval, Lumacan will be eligible for 3 years of exclusivity in the United States.

Salix will pay Photocure a $4.0 million upfront fee. Financial terms of the transaction are weighted on the successful regulatory approval and subsequent
commercial success of Lumacan, with potential milestone payments totaling $126.5 million. Salix also will pay royalties on net sales and non-U.S. sublicense revenue. Salix will control and fund the worldwide development, registration and
commercialization activities for Lumacan. Photocure will fund up to $3.0 million of formulation development activities.

Colon cancer is the
third most frequently diagnosed cancer in the United States, excluding skin cancer. Colonoscopy is the key to early detection and prevention. Approximately 14 million

Photocure signs agreement with Salix Pharmaceuticals for Lumacan

Oslo, Norway, 20 October, 2010;Photocure (OSE: PHO), a Norwegian specialty pharmaceutical company focused in dermatology and cancer,
announced today it has signed a strategic global agreement with Salix Pharmaceuticals Ltd. (NASDAQ:SLXP), the US specialty pharmaceutical company focused on gastrointestinal diseases, for the development and commercialisation of Lumacan. Lumacan is
a photodynamic colorectal diagnostic intended to significantly improve the detection of precancerous and cancerous lesions in the colon through fluorescence diagnosis.

Under the agreement, Salix will obtain an exclusive worldwide license to Lumacan excluding the Nordic region. Photocure will receive a signing fee of US$4 million and is entitled to receive additional
milestone payments totalling up to US$126.5 million, if certain conditions are satisfied. The milestones relate to development, regulatory events and sales achievement. In addition to the milestones, Salix will pay Photocure tiered double digit
royalties on net sales and pay a percentage of all Salix sublicense revenue worldwide outside of the US. Salix will control and cover development, registration and commercialisation costs for Lumacan worldwide, with Photocure covering certain costs
of formulation development up to US$3 million.

Photocure has retained the rights to market and sell Lumacan in the Nordic countries. In
addition to the development of Lumacan for colorectal cancer, Salix has the exclusive right to explore and develop products for additional indications involving the diagnosis of gastrointestinal dysplasia and cancer. Payments for products in respect
of any such additional indications will be negotiated if and when new product development is initiated.

Colon cancer is traditionally
diagnosed through colonoscopies (visual examination) with white light. It is increasingly being recognized that standard white-light colonoscopy has limitations in the detection of colon cancer. Earlier studies undertaken by Photocure have
demonstrated an increased detection rate of nearly 40% when Lumacan-colonoscopy diagnostic was used. Lumacan is currently in Phase I/II trials.

Photocure and Salix believe earlier detection and diagnosis of precancerous and cancerous lesions in the colon could ultimately lead to better targeted
therapeutic care and increased colorectal cancer survival rates in patients. Lumacan is being developed for use in conjunction with standard white light colonoscopy diagnosis. Annually, approximately 14 million colonoscopies are performed in
US. Lumacan will target high risk screening patients and diagnostic patients in follow-up of colon cancer. Collectively, these subgroups are estimated to be approximately 20% of total colonoscopies undertaken.

Chief Executive Officer of Photocure, Kjetil Hestdal, said We are delighted to have signed this agreement with Salix Pharmaceuticals. The value of
the deal in this early clinical phase reflects the great potential of Lumacan. Given its successful expertise and experience in developing and marketing treatments for gastrointestinal diseases, Salix is an excellent partner to take Lumacan to the
market. We believe this agreement represents the best way to accelerate the development of Lumacan and create long term value for our shareholders. We look forward to working closely with Salix on the future development of Lumacan.

Chief Executive Officer of Salix Pharmaceuticals, Carolyn Logan, stated We believe Lumacan is truly an innovative and groundbreaking diagnostic
which should complement our portfolio of gastrointestinal offerings. Lumacans efficacy results thus far have been promising and show great potential if approved for marketing by the FDA. Lumacan will be our first gastrointestinal diagnostic
product and we hope to save lives through earlier and more successful colon cancer detection.

About Lumacan and colon cancer

Colon
cancer is traditionally diagnosed through colonoscopies (visual examination) with white light. It is increasingly being recognized that standard white-light colonoscopy has considerable limitations in the optimal detection of colon cancer. Lumacan
is being developed to increase the detection rate for polyps and colon cancer through fluorescence diagnosis. Earlier studies undertaken by Photocure have shown a significant increased detection rate when Lumacan-colonoscopy diagnostic was used. It
is currently in Phase I/II trials. The market for colonoscopies is growing as a result of extensive patient screening programs in Europe and USA. In the US, it is estimated approximately 14 million colonoscopies are undertaken annually for
diagnosis of colon cancer.
