In the event that GSK elects, in its sole discretion, not to launch and commercialize Licensed Products for applications in the Field in any country in the GSK Territory, GSK shall promptly notify Santarus in writing of such decision, in which case Santarus shall have the right to terminate this Agreement with respect to such country in accordance with Section 13.3. For clarity, nothing in the previous sentence shall be construed to prejudice GSK’s right to terminate this Agreement pursuant to Section 13.4.2.

4.2 Specific Requirements. Without limiting the provisions of Section 4.1, GSK shall file a MAA in (a) each Major GSK Country (other than the People’s Republic of China) within three (3) years after the Effective Date and (b) the People’s Republic of China within four (4) years after the Effective Date. In addition, GSK shall launch the Licensed Products (i) within six (6) months after the date of receipt of Marketing Authorization in each Major GSK Country and (ii) within twelve

(12) months of receipt of Marketing Authorization in each other country in the GSK Territory, but in the case of (i) and (ii) no later than five (5) years after the Effective Date.

In the event that GSK fails to file an MAA or launch License Products within the timeframes set forth in this Section 4.2 in a country (each such failure, a “Diligence Failure”), then Santarus shall have as its sole remedy for such breach, but without limiting the remedies for other breaches the right to terminate this Agreement with respect to such country in accordance with Section 13.3.

4.3 Managed Care. For clarity, GSK shall be responsible for decisions and negotiations with relevant governmental authorities, agencies and managed care organizations (including health maintenance organizations, preferred provider organizations, exclusive provider organizations, independent practice associations, point-of-service plans and the like) and other institutions regarding price and reimbursement status of Licensed Products in the GSK Territory.

The foregoing covenants shall not restrict GSK or any Affiliate or Sublicensee from obtaining rights to, or engaging in research and development activities related to, products in such class during the restricted time period, so long as GSK or its Affiliate or Sublicensee does not engage in the activities set forth in the first sentence of this Section 6.1.1.

6.1.2 By Santarus. Until the earlier of (a) the fifth (5^th) anniversary of the Effective Date or (b) termination of GSK’s license pursuant to Section 2.1.1 to sell, offer for sale and import Licensed Products in a given country within the GSK Territory, neither Santarus nor any of its Affiliates will directly or indirectly distribute, market, promote, detail, advertise or sell any PPI Pharmaceutical Product containing one or more PPIs which is either formulated in combination with one or more buffering agents, or which is otherwise formulated to provide, in either case, for immediate release of the PPI in or for such country in the GSK Territory. On or after the fifth (5^th) anniversary of the Effective Date (for so long as GSK’s license under Section 2.1.1 is still in effect with respect to the applicable country), Santarus and any Affiliates shall have the right to directly or indirectly distribute, market, promote, detail, advertise or sell any PPI Pharmaceutical Product containing one or more PPIs which is either formulated in combination with one or more buffering agents, or which is otherwise formulated to provide, in either case, for immediate release of the PPI, in or for such country in the GSK Territory; provided that Santarus shall discuss with GSK the out-license of such product to GSK for such country; and provided further that in the event that Santarus grants the right to commercialize the product to any Third Party, or commercializes the product in its own right, in such country in the GSK Territory, GSK shall be released from its obligations under Section 6.1.1 on the first commercial sale of such product in such country by such Third Party or Santarus, as the case may be. The foregoing covenants shall not restrict Santarus or any Affiliate from obtaining rights to, or engaging in research and development activities related to, products in such class during the restricted time period, so long as Santarus or its Affiliate does not engage in the activities set forth in the first sentence of this Section 6.1.2.

6.2 Know-How Restrictions and Firewall. GSK shall not, and shall ensure its Affiliates and Persons acting under its authority do not, use or practice (or authorize the use or practice of) any Santarus Know-How or other Confidential Information of Santarus (including Data regarding the manufacture, formulation, release profile, efficacy or safety, use, sale or promotion of any Licensed Product, for the purposes of manufacturing, developing or commercializing any product (other than

Licensed Products for applications in the Field in the GSK Territory in accordance with this Agreement or the PR Product in the PR Territory in accordance with the Distribution Agreement). GSK recognizes that, while GSK is Santarus’ licensee of Licensed Products in the GSK Territory pursuant to this Agreement, GSK could, subject to Section 6.1 and this Section 6.2, develop a PPI Pharmaceutical Product which would, once launched, compete with Santarus with respect to the Licensed Products. GSK acknowledges that Santarus is disclosing to GSK Santarus Know-How and other Confidential Information of Santarus for GSK’s use solely with respect to the Licensed Products for applications in the Field in the GSK Territory under this Agreement (or as otherwise provided with respect to PR Products in the PR Territory pursuant to the Distribution Agreement), and GSK agrees not to use the Santarus Know-How or other Confidential Information of Santarus, directly or indirectly, in the research, manufacture, development, sale or marketing of any PPI Pharmaceutical Product other than (a) Licensed Products to the extent permitted under this Agreement or (b) the PR Product to the extent permitted under the Distribution Agreement. GSK shall limit disclosure of Santarus Know-How or other Confidential Information of Santarus to its and its Affiliates’ employees, consultants and other agents located in the Territory (or the PR Territory to the extent permitted under and in accordance with the Distribution Agreement) who need to access such Santarus Know-How or other Confidential Information of Santarus for the development, manufacture or commercialization of Licensed Products in the GSK Territory in accordance with this Agreement (or the PR Territory to the extent permitted under the Distribution Agreement) and who are bound by obligations of confidentiality and non-use no less burdensome than those set forth in this Agreement. Santarus Know-How or other Confidential Information of Santarus shall not be disclosed to any of GSK’s or its Affiliates’ employees, consultants or other agents involved in the research, development, manufacture or commercialization of any PPI Pharmaceutical Product other than Licensed Products as permitted under this Agreement or the PR Product as permitted under the Distribution Agreement, nor use or consider any such information or GSK’s plans with regard to any Licensed Product in the development, manufacture or commercialization of any PPI Pharmaceutical Product, and GSK agrees to institute reasonable procedures and safeguards intended to prevent such prohibited disclosures.

6.3 No Patent Challenges. In partial consideration for the licenses and other rights granted herein, and access to Santarus Know-How or other Confidential Information of Santarus, GSK agrees that if GSK or any of its Affiliates commences, participates in or actively supports in any way any challenge to the validity, enforceability, claim construction or coverage of any Patents Controlled by Santarus claiming or covering the composition, formulation, manufacture, use or sale of Licensed Products in the GSK Territory in any court or before any government or regulatory agency (national or international) with authority to determine the validity, enforceability or scope of such patents, or cause or request a review by any such court or government or regulatory agency of the same, then at any time thereafter Santarus shall be entitled to elect to treat such activity as permissive termination by GSK under Section 13.4.2 of this Agreement in its entirety, and such termination shall be effective immediately upon written notice to GSK.

6.4 Missouri Agreement. Santarus shall have the obligation to pay all amounts owed to the UMissouri under the Missouri Agreement, and in accordance with the terms set forth therein, with respect to sales of Licensed Products by GSK (and any of its Affiliates and Sublicensees) pursuant to the terms and conditions of this Agreement. It is understood and agreed that the sublicense to GSK under this Agreement of rights licensed to Santarus under the Missouri

Agreement is subject to the terms and conditions of the Missouri Agreement applicable to such a sublicense, and that such obligations are incorporated by reference herein. In the event of termination (but not earlier expiration) of the Missouri Agreement during the Term of this Agreement, (a) GSK’s sublicense under the Missouri Agreement shall be assigned by Santarus to the UMissouri with respect to Licensed Products for applications in the Field in the GSK Territory, and this Agreement will be assigned in part to the UMissouri to effect such assignment of the sublicense, (b) this Agreement (including all payment obligations of GSK hereunder) shall otherwise be retained by Santarus with respect to all matters other than the sublicense of rights under the Missouri Agreement and (c) GSK shall thereafter be responsible for making all payments that would have been owed by Santarus to UMissouri pursuant to the Missouri Agreement (if the Missouri Agreement had not been terminated) in respect of GSK’s, its Affiliates’ and their Sublicensees’ sales of Licensed Products for applications in the Field in the GSK Territory after the date of such assignment; provided that GSK shall have the right to offset the amounts so paid to UMissouri in respect of the sales of Licensed Products during the Term against amounts due hereunder to Santarus with respect to such sales.

6.5 Reporting. Without limiting any other provision herein, GSK agrees to provide Santarus during the Term with annual reports describing the activities taken during the previous period and GSK’s plans for activities during the upcoming period with respect to GSK’s obligations to develop (including plans for and results of non-clinical and clinical studies regarding Licensed Products), manufacture (including establishment of Third Party contractors) and commercialize the Licensed Products (including sales forecasts) and interactions with Regulatory Authorities in the GSK Territory with respect to the Licensed Products (including status of MAA filings and receipt of Market Authorizations in each country within the GSK Territory). On an annual basis, the Parties shall meet (telephonically or in person) to discuss GSK’s then current and anticipated development, manufacturing, commercialization and regulatory activities conducted by or under authority of GSK in or for the GSK Territory.

ARTICLE 7

PAYMENTS; ROYALTIES; REPORTS

7.1 Up-Front Payment. Within three (3) days after the Effective Date, GSK shall pay Santarus an up-front license fee of Eleven Million Five Hundred Thousand U.S. Dollars (US$11,500,000), which amount shall be non-refundable and non-creditable against other amounts due to Santarus hereunder or under the Distribution Agreement.

7.2 Royalties on Net Sales. In partial consideration for the rights and licenses granted to GSK under this Agreement, GSK shall pay to Santarus tiered royalties on Net Sales of Licensed Products in the GSK Territory during the Term at the applicable rates set forth in Section 7.2.1, subject to adjustment as set forth in Section 7.2.2 below and subject to Section 7.2.3. Royalties with respect to Net Sales made in each Calendar Quarter shall be paid within thirty (30) days following the applicable Calendar Quarter end.

7.2.1 Royalty Rates. It is understood and agreed that applicable royalty rates on Net Sales of Licensed Products under this Agreement shall be determined based on the total aggregate of (a) Net Sales of Licensed Products under this Agreement, together with (b) any and all Net Sales (as defined under the Distribution Agreement) of PR Products (as

defined under the Distribution Agreement) under the Distribution Agreement (collectively, “Aggregate Product Net Sales”) during the applicable calendar year, as follows:


Aggregate Product Net Sales (in U.S. Dollars) During Applicable Calendar Year	Royalty Rate
Portion under $40 Million		17.5	%
Portion between $40 and $80 Million		22.5	%
Portion over $80 Million		27.5	%

7.2.2 Reduction for Substantial Generic Competition.

(a) In the event that, and for so long as, there exists Substantial Generic Competition in a Major GSK Country: (a) the royalty rates payable under Section 7.2.1 for Net Sales in such country shall be reduced from the rates of 17.5%, 22.5% and 27.5% specified in Section 7.2.1 above to 12.5%, 15% and 17.5%, respectively, and (b) in the event that Santarus’ royalty obligation under the Missouri Agreement for sales of Licensed Products hereunder by GSK is reduced on account of such Substantial Generic Competition in such country, then the royalty owed by GSK to Santarus for such Net Sales shall be further reduced by the same percentage reduction under the Missouri Agreement. As used herein, “Substantial Generic Competition” means that, during the immediately preceding two (2) Calendar Quarters, combined sales of Generic Competitive Products in a particular country in the GSK Territory by Third Parties equate to at least twenty-five percent (25%) of total sales of Licensed Products in the applicable country on a standard unit basis, as measured by IMS standard unit data. For clarity, the royalty reduction set forth in this Section 7.2.2 shall only apply for so long as there is Substantial Generic Competition, and the royalty rates set forth in Section 7.2.1 shall again apply if Substantial Generic Competition ceases at any time during the Term following a royalty reduction pursuant to this Section 7.2.2. GSK shall notify Santarus in writing within ten (10) days after GSK becomes aware of any Substantial Generic Competition.

(b) Allocation of Reduction Among Royalty Tiers. In the event that Substantial Generic Competition (as set forth in this Section 7.2.2 or Section 6.2.2 of the Distribution Agreement, as applicable) occurs in any one or more, but not all, of the countries in the GSK Territory under this Agreement and the Territory under the Distribution Agreement, then the royalty reduction described in Section 7.2.2(a) above and under Section 6.2.2(a) of the Distribution Agreement shall be allocated to a portion of Net Sales in each royalty tier described in Section 7.2.1 above (or Section 6.2.1 of the Distribution Agreement, as applicable) equal to the proportion of Aggregate Product Net Sales under this Agreement and the Distribution Agreement eligible for such reduction compared to the total Aggregate Product Net Sales. By way of example, and not limitation, if the total Aggregate Product Net Sales for the first Calendar Quarter of a given calendar year is $50 million, and $10 million of such Aggregate Product Net Sales occurs in countries with Substantial Generic Competition (meaning 20% of total Aggregate Product Net Sales for such Calendar Quarter occurred in countries with Substantial Generic Competition), then (A) the reduced royalty rates set forth in Section 7.2.2(a) above and in Section 6.2.2(a) of the Distribution Agreement shall apply to 20% of the Aggregate Product Net Sales in each applicable royalty tier, and (B) the

unreduced royalty rates set forth in Section 7.2.1 above and in Section 6.2.1 of the Distribution Agreement shall apply to the remaining 80% of the Aggregate Product Net Sales in each applicable royalty tier.

7.2.3 Waiver of Certain Amount of Initial Royalties. To support GSK’s commercialization of Licensed Products in the GSK Territory and help defray start-up costs of GSK, Santarus agrees to waive the first Two Million Five Hundred Thousand U.S. Dollars (U.S. $2,500,000) of combined royalties due from GSK under this Section 7.2 of this Agreement and Section 6.2 of the Distribution Agreement. For clarity, the waiver of royalties under this Section 7.2.3 and under Section 6.2. of the Distribution Agreement together shall not exceed Two Million Five Hundred Thousand U.S. Dollars (U.S. $2,500,000) in the aggregate.

7.2.4 Royalty Term; Buyout Payment. The obligation of GSK to pay royalties under this Section 7.2 shall continue for so long as GSK manufactures, markets, promotes, uses or sells Licensed Product in the GSK Territory, unless GSK pays to Santarus within thirty (30) days following the twentieth (20^th) anniversary of the Effective Date an amount (the “Buyout Payment”) equal to fifty percent (50%) of the aggregate Net Sales of Licensed Product in the GSK Territory during the four (4) Calendar Quarters completed immediately preceding the twentieth (20^th) anniversary of the Effective Date, Upon GSK’s timely payment of the Buyout Payment, GSK’s obligation to pay royalties under this Section 7.2 shall cease; provided, however, that GSK shall thereafter continue to pay Santarus continuing royalties equal to the amount of royalties (if any) that Santarus is required to pay under the Missouri Agreement with respect to Licensed Products sold by or under authority of GSK in the GSK Territory.

7.2.5 Convenience. GSK agrees that substantial commercial value has been and will be contributed by Santarus’ grant to GSK of the rights and licenses under this Agreement with respect to the Licensed Products in the GSK Territory and other rights and licenses conveyed to GSK on the terms and conditions set forth in this Agreement, and acknowledges that Santarus may not Control Patents covering the manufacture, use or commercialization of Licensed Products throughout the Term or throughout the GSK Territory. For their mutual convenience, the Parties have agreed to the royalty rates and payment obligations set forth in this Agreement with respect to Net Sales of Licensed Products in the GSK Territory, regardless of whether the manufacture, use or commercialization of Licensed Products sold by GSK hereunder is covered by Patents Controlled by Santarus.

7.3 Withholding. It is the understanding of the Parties that GSK will not be required by Applicable Law to withhold taxes from royalty payments due to Santarus under Section 7.2. GSK shall take all reasonable steps to mitigate the impact of withholding taxes on both Parties in the event that it wishes to assign its rights and obligations under this Agreement to an Affiliate or where GSK is required under Applicable Law to withhold taxes from royalties due to Santarus under Section 7.2, the Parties shall negotiate in good faith a reasonable allocation of such taxes between the Parties, taking into account the ability of either party to recover any such taxes that have been withheld. In the event that GSK is required under Applicable Law to withhold taxes from any other amounts payable to Santarus under this Agreement, including payments for reimbursement of Santarus’ expenses, it shall reimburse Santarus (without withholding) in respect of any amounts so withheld in the event and to the extent that Santarus is unable to utilize a tax credit with respect to such withholding for the tax year in which the withholding occurred.

7.4 Method of Payments. All amounts payable to Santarus under this Agreement shall be paid in U.S. Dollars by wire transfer to a bank account it designates. All payments hereunder shall be made in the legal currency of the United States of America, and all references to “$” or “Dollars” shall refer to United States dollars. When Licensed Products are sold for monies other than Dollars, the royalties will first be determined in the foreign currency of the country in which such Licensed Products were sold and then converted into equivalent Dollars. The exchange rate will be that rate quoted by The Wall Street Journal on the last Business Day of the reporting period. Except as otherwise set forth in this Agreement, including Section 7.2 with respect to royalty payments, all payments due to a Party hereunder shall be due and payable within thirty (30) days of an invoice from the other Party. All payments under this Agreement shall bear interest from the date due until paid at a rate equal to one and one-half percent (1.5%) per month, or, if less, the maximum rate permitted by Applicable Law. The payment of such interest shall not limit either Party from exercising any other rights it may have as a consequence of the lateness of any payment or breach of this Agreement by the other Party.

7.5 Royalty Reports. GSK shall, within thirty (30) days following each Calendar Quarter, make quarterly written reports to Santarus stating in each report, separately for GSK and each of its Affiliates and Sublicensees, and by country: (a) the number, description and aggregate gross amounts invoiced and Net Sales of each Licensed Product sold in the GSK Territory during the immediately preceding quarter, including reasonably detailed descriptions of all itemized deductions from gross amounts invoiced; (b) the number of Licensed Products sold or distributed on a product-by-product basis; (c) the calculated amount of royalties due Santarus on account of such Net Sales; (d) the basis for calculation of royalties due to Santarus, including applicable deductions or adjustments; (e) the exchange rates used in making such calculations; and (f) the date of first commercial sale of each Licensed Product. If no royalties are due for a particular quarter, GSK shall so report to Santarus. GSK shall also make monthly interim written reports to Santarus stating in each such report the aggregate Net Sales of Licensed Products sold in each country in the GSK Territory during the immediately preceding month. GSK’s reports under this Section 7.5 shall be transmitted to Santarus by email (to ***@*** and ***@***, or to such other e-mail address(es) as Santarus may from time to time designate in writing). Quarterly reports shall be sent within thirty (30) days after the end of each Calendar Quarter and monthly interim reports shall be sent within ten (10) days after the end of each calendar month. The reports required under this Section 7.5 may be combined with royalty reports due under the Distribution Agreement; provided that any such combined report shall set forth the required information separately for each country in the GSK Territory.

7.6 Audits. GSK shall keep, and cause its Affiliates and any Sublicensees to keep, complete and accurate records in sufficient detail to enable a calculation of royalties due to Santarus on account of Net Sales of Licensed Products in the GSK Territory, determined in accordance with GAAP (including calculation of gross amounts invoiced for each Licensed Product, Net Sales of each Licensed Product, all itemized deductions from gross amounts invoiced taken to calculate Net Sales, and amounts payable hereunder to Santarus for each Licensed Product). For the sole purpose of verifying amounts relating to this Agreement, Santarus shall have the right no more than one time

each calendar year, at its own expense, to have agents or representatives of Santarus or any of its licensors of Santarus Patents review such records for the twelve (12) Calendar Quarters preceding such review in the location(s) where such records are maintained by GSK and its Affiliates upon reasonable notice and during regular business hours. Results of such review shall be made available to GSK. The records and results of such audits shall be deemed Confidential Information of GSK. In the event that such a review identifies an underpayment greater than five percent (5%) of the amounts that were otherwise due for a calendar year during such period, Santarus shall have the right to conduct a similar review of the records for the eight (8) Calendar Quarters immediately preceding the period initially reviewed. Further, if the review reflects an underpayment to Santarus, such underpayment shall be promptly remitted to Santarus, together with interest calculated in the manner provided in Section 7.4. If the review reflects an overpayment to Santarus, such overpayment shall be credited against the next payment due Santarus. If the review reveals an underpayment of more than three percent (3%) of the amounts due for any period of four (4) consecutive Calendar Quarters, GSK shall reimburse Santarus for the costs of such audit.

8.1 Inventions.

8.1.1 General. With respect to inventions and intellectual property arising during the course of, or as a result of, each Party’s performance under this Agreement, (a) title to all inventions and intellectual property made solely by GSK employees or its agents hereunder (each a “GSK Invention”) shall be solely owned by GSK, (b) title to all inventions and intellectual property made solely by Santarus employees or its agents hereunder (each a “Santarus Invention”) shall be solely owned by Santarus, and (c) title to all inventions and intellectual property made by jointly by GSK employees or agents and Santarus employees or agents shall be jointly owned. Inventorship of inventions shall be determined in accordance with the laws of inventorship of the country in which the patent applications directed to the relevant inventions are filed.

purposes of this Agreement, as set forth in this Section 8.1.2. Santarus hereby covenants that it will use Commercially Reasonable Efforts, in any negotiations with respect to agreements entered into with Third Parties after the Effective Date with respect to Licensed Products, not to license to the Third Party Santarus’ rights to market, promote, advertise, sell or distribute under any New Form or New Indication in each country within the GSK Territory for which GSK retains its license pursuant to Section 2.1.1 to sell, offer for sale and import Licensed Products in such country. Promptly after the initiation of marketing of such New Form or New Indication in the United States by or under the authority of Santarus, Santarus shall notify GSK in writing describing the same and providing such Data in Santarus’ Control as may be reasonably necessary to evaluate whether GSK desires to exercise its option described in this Section 8.1.2. In such case, GSK shall notify Santarus in writing within sixty (60) days of receipt of Santarus’ notice as to whether it desires to exercise such option. If GSK so notifies Santarus that it desires to exercise its option, then the Parties shall negotiate in good faith for a period of at least sixty (60) days to determine the portion of Santarus’ research and development costs and expenses incurred for such New Form or New Indication that GSK shall be required to pay to Santarus, which determination shall be based upon the likely commercial returns to each Party from such New Form or New Indication in its respective territory and the risk taken by Santarus in developing the New Form or New Indication; provided that if the Parties are unable for any reason to agree on such payment amount during such period, then either Party may submit such issue for dispute resolution pursuant to Article 14. Notwithstanding anything herein to the contrary, the option granted in this Section 8.1.2 shall not include any New Form or New Indication subject to payment obligations to a Third Party (and Santarus shall promptly disclose such obligations to GSK in writing), unless GSK also agrees in writing to reimburse all amounts owed to such Third Party as a result of GSK’s exercise of its license rights to such New Form or New Indication. In the event GSK does not exercise its option with respect to a particular New Form or New Indication, Santarus shall not have the right, itself or through its Affiliates or Third Parties, to sell, offer to sell and import for sale such New Form for any use or Licensed Products (or any New Form thereof) for such New Indication, respectively, in any given country in the GSK Territory for so long as GSK retains its license pursuant to Section 2.1.1 to sell, offer for sale and import Licensed Products in such country.

8.2 Patent Prosecution.

8.2.1 Santarus Patents. As between the Parties, Santarus shall have the right, to control the Prosecution and Maintenance of the Santarus Patents using counsel of its choice and GSK agrees to reimburse Santarus for Santarus’ reasonable out-of-pocket expenses (including amounts reimbursed therefor to UMissouri or any other licensor of Santarus Patents) in connection with such activities with respect to the GSK Territory as they are incurred. GSK may elect upon thirty (30) days’ prior written notice to Santarus not to continue paying for Prosecution and Maintenance of any Santarus Patent, in which case, the Patent shall be excluded from the Santarus Patents and all of GSK’s license rights under such Patent shall cease as of the effective date of GSK’s notice. Santarus agrees to keep GSK reasonably informed of such activities in the GSK Territory with respect to claims that are subject to GSK’s license rights under this Agreement. GSK shall have the right to advise and comment upon the prosecution of patent application claims that are subject to GSK’s license rights under this Agreement in the GSK Territory. Santarus shall, in good faith, consider and incorporate such advice and comments of GSK to the extent reasonably acceptable to Santarus and its licensor of such patent application, if applicable. Upon the request of GSK, the Parties shall discuss in good faith the filing at GSK’s expense of any continuation,

continuation-in-part or divisional to any patent or patent application within the Santarus Patents to be filed in the GSK Territory beyond those Santarus may elect to file, which continuation, continuation-in-part or divisional contains claims that are subject to GSK’s license rights under this Agreement.

8.2.2 Joint Patents. The Parties shall jointly Prosecute and Maintain Patents claiming inventions that are owned jointly by GSK and Santarus under Section 8.1.1, and each Party agrees to take all reasonable action to cooperate fully with the other Party in this regard. Except as otherwise provided in Section 8.2.1, each Party shall be responsible for fifty percent (50%) of the out-of-pocket expenses in connection with Prosecution and Maintenance of jointly owned Patents; provided that if either Party notifies the other Party in writing, referencing this Section 8.2.2 and the applicable Patent that such Party elects not to be responsible for any further costs under this Section 8.2.2, such Party shall not be required to reimburse the other Party for its share of costs incurred under this Section 8.2.2 with respect to such Patent after the date of receipt of written notice, and all right, title and interest in and to such Patent (including any Patents issuing therefrom) shall be owned by the other Party, and such Patent shall be excluded from the Santarus Patents for all purposes of this Agreement (subject to the licenses granted to Santarus under this Agreement).

8.2.3 Prosecute and Maintain. For purposes of this Section 8.2, “Prosecution and Maintenance” shall mean, with respect to a Patent, the preparing, filing, prosecuting, nationalizing, registering and maintaining such Patent, as well as re examinations, reissues, confirmations, renewals, requests for Patent term extensions, supplemental protection certificates and the like with respect to such Patent, together with the conduct of interferences, the defense of oppositions and other similar proceedings with respect to the particular Patent; and “Prosecute and Maintain” shall have the correlative meaning.

8.3 Defense of Third Party Infringement Claims. If any Licensed Product developed, manufactured or commercialized by or under authority of GSK or its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent relating to the development, manufacture or commercialization of such Product for applications in the Field in the GSK Territory, the Party first having notice of the claim or assertion shall promptly notify the other Party in writing, and, without limiting GSK’s indemnification obligations under Section 10.2, the Parties shall promptly confer to consider the claim or assertion and the appropriate course of action. Unless the Parties otherwise agree in writing, each Party shall have the right to defend itself against a suit that names it as a defendant (the “Defending Party”). Neither Party shall enter into any settlement of any claim described in this Section 8.3 that adversely affects the other Party’s rights or interests without such other Party’s written consent, which consent shall not be unreasonably conditioned, withheld or delayed. In any event, the other Party shall reasonably assist the Defending Party and cooperate in any such litigation at the Defending Party’s request and expense.

8.4 Enforcement of Santarus Patents.

8.4.1 In-Licensed Patents. It is understood and agreed that, with respect to Patents within the Santarus Patents that are owned by a Third Party and licensed to Santarus, the provisions set forth in this Section 8.4 shall apply only to the extent consistent with Santarus’ rights under the applicable in-license for such Santarus Patents.

8.4.2 General Enforcement. Each Party shall promptly notify the other Party in writing of any actual or suspected infringement of any claim in a Santarus Patent in the GSK Territory, which claim is subject to GSK’s license rights hereunder (including via unauthorized importation into the GSK Territory for sale in the GSK Territory) or is subject to a declaratory judgment action alleging non-infringement or unenforceability. Such notice shall specify in reasonable detail the nature of such actual or suspected infringement or judicial action. GSK shall not give notice (written or other) of infringement of any of the Santarus Patents to any Third Party without Santarus’ prior written consent; provided, however, that GSK may give such notice to a Third Party, without Santarus’ consent but upon thirty (30) days’ prior written notice to Santarus, if (a) Santarus has declined to take steps to abate such infringement and GSK has the right to enforce the Santarus Patents against such Third Party infringer as set forth in this Section 8.4.2; or (b) disclosure is required by securities or other Applicable Laws to which GSK is subject; or (c) disclosure is made in the course of a financial audit. Unless the Parties otherwise mutually agree in writing, Santarus shall have the initial right, using counsel of its choice, to enforce the Santarus Patents or defend any declaratory action with respect thereto (an “Enforcement Action”), at its expense, and GSK shall give all reasonable assistance (excluding financial assistance) to Santarus in such Enforcement Action, at Santarus’ expense. However, if (i) Santarus elects in writing not to bring or defend an Enforcement Action with respect to any Licensed Product in the GSK Territory for use in the Field for which GSK has license rights under this Agreement or (ii) within ninety (90 days following a written request by GSK to do so and confirmation of facts reasonably supporting existence of such actual or suspected infringement with respect to Licensed Products in the Field and GSK Territory for which GSK has license rights under this Agreement, Santarus fails to bring or defend an Enforcement Action or take other commercially reasonable action to protect the Santarus Patents from such infringement, or to abate such infringement (which may in Santarus’ discretion include, without limitation, negotiations for a license (not in conflict with the licenses granted GSK herein) from Santarus for the manufacture, use or sale of Licensed Products to be sold outside the GSK Territory), then GSK shall have the right, at its sole discretion, to institute an Enforcement Action in its own name using counsel of its choice, at its own expense, and with the right to control the course of such Enforcement Action (and Santarus shall provide all reasonable assistance, other than financial, to GSK for such Enforcement Action, at GSK’s expense, including joining such Enforcement Action if necessary to maintain the Enforcement Action, and Santarus shall have the right to join and participate in the Enforcement Action whether or not such joinder is requested by GSK).

8.4.3 Recoveries. Any recovery received as a result of any Enforcement Action to enforce a Santarus Patent pursuant to this Section 8.4 shall be used first to reimburse the Parties for the costs and expenses (including attorneys’ and professional fees and amounts paid or payable to the UMissouri) incurred in connection with such Enforcement Action (and not previously reimbursed). Of any remaining amounts, the amount (if any) which is required to be paid to UMissouri under the terms of the Missouri Agreement or any other licensors of the applicable Santarus Patents under the terms of the respective in-license agreement, shall then be paid to UMissouri or such other licensor, and any amounts remaining thereafter shall (a) to the extent attributable to infringement of claims of the Santarus Patents in the GSK Territory for which claims GSK has license rights under this Agreement), be shared seventy-five percent (75%) to GSK and twenty-five percent (25%) to Santarus and (b) to the extent not attributable to infringement of claims of the Santarus Patents in the GSK Territory for which claims GSK has license rights under this Agreement, be distributed to, or retained by, Santarus.

8.4.4 Limits on Disposition. In no case may GSK enter into any settlement or consent judgment or other voluntary final disposition that: (a) extends, or purports to exercise, GSK’s rights under the Santarus IP beyond the rights expressly granted pursuant to this Agreement, (b) makes any admission regarding wrongdoing by Santarus or UMissouri or any other licensor of Santarus Patents, or the invalidity, unenforceability or absence of infringement of any Santarus Patents; (c) subjects Santarus to an injunction or other equitable relief; or (d) obligates Santarus to make a monetary payment; in all cases without the prior written consent of Santarus. Similarly, in no case may Santarus enter into any settlement or consent judgment or other voluntary final disposition that: (i) limits GSK’s rights under the Santarus IP or under this Agreement other than as expressly stated herein; (ii) makes any admission regarding wrongdoing on the part of GSK, an Affiliate or Sublicensee, or the invalidity, unenforceability or absence of infringement of any GSK IP; (iii) subjects GSK to an injunction or other equitable relief; (iv) obligates GSK to make a monetary payment; or (iv) extends, or purports to exercise, Santarus’ rights under the GSK IP beyond the rights expressly granted pursuant to this Agreement; in all cases without the prior written consent of GSK.

(b) the distribution, marketing, advertisement, promotion or sale of Licensed Product in the GSK Territory, by or under authority of Santarus after termination of this Agreement;

(c) the distribution, marketing, advertisement, promotion or sale of Licensed Products outside of the GSK Territory and outside of the Territory under the Distribution Agreement, including any actual or alleged infringement of a Third Party’s intellectual property rights, by or under authority of Santarus or its Affiliates; or

10.2 GSK Indemnification Obligations. GSK will indemnify, defend and hold harmless Santarus, its Affiliates and licensors (including the UMissouri), and their respective officers, directors, trustees, agents, curators and employees, inventors of, and sponsors of the research that led to, any of the inventions covered by Santarus Patents, and their employees (collectively, “Santarus

10.3 Indemnity Procedures. A Person entitled to indemnification pursuant to either Section 10.1 or Section 10.2 will hereinafter be referred to as an “Indemnitee.” A Party obligated to indemnify an Indemnitee hereunder will hereinafter be referred to as an “Indemnitor.” In the event an Indemnitee is seeking indemnification under either Section 10.1 or Section 10.2, the Indemnitee will inform the Indemnitor of a claim as soon as reasonably practicable after it receives notice of the claim, it being understood and agreed that the failure by an Indemnitee to give notice of a claim as provided in this Section 10.3 will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that such Indemnitor is actually prejudiced as a result of such failure to give notice. The Indemnitee will permit the Indemnitor to assume direction and control of the defense of the claim (including, subject to this Section 10.3, the right to settle the claim solely for monetary consideration to be paid by the Indemnitor), and, at the Indemnitor’s expense, will co-operate as reasonably requested in the defense of the claim.

The Indemnitor may not settle such action or claim, or otherwise consent to an adverse judgment in such action or claim, in any manner which admits liability or wrongdoing of the Indemnitee, or which would subject the Indemnitee to an injunction, or if such settlement or judgment would materially diminish or limit or otherwise adversely affect the rights, activities or financial interests of the Indemnitee, without the express written consent of the Indemnitee.

10.4 No Punitive or Exemplary Damages. EXCEPT FOR BREACHES OF THE OBLIGATIONS SET FORTH IN SECTIONS 6.1, 6.2 AND 6.3 AND ARTICLE 12, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF PROFITS) SUFFERED BY THE OTHER PARTY UNDER THIS AGREEMENT, EXCEPT TO THE EXTENT A PARTY IS REQUIRED TO INDEMNIFY THE OTHER PURSUANT TO THIS ARTICLE 10 WITH RESPECT TO ANY SUCH DAMAGES PAID TO A THIRD PARTY AS PART OF A CLAIM.

Santarus shall maintain such insurance during the Term and thereafter for a period of five (5) years. Santarus shall give GSK at least thirty (30) days notice of any cancellation or termination of such insurance.

(a) The Parties will not disclose, directly or indirectly, in any manner whatsoever to any Third Parties any Confidential Information received from the other Party (the “Disclosing Party”) without first obtaining the written consent of the Disclosing Party, and the other Party (“Recipient”) will keep confidential, all of the Disclosing Party’s Confidential Information that is disclosed to Recipient. Recipient agrees to use the same level of care in safeguarding the Disclosing Party’s Confidential Information that Recipient uses with its own confidential information of a similar nature, but in no event less than reasonable care. Recipient will restrict disclosure of the Disclosing Party’s Confidential Information solely to those of its (or its Affiliate’s) employees or representatives having a need to know such Confidential Information in order to exercise a right granted or fulfill an obligation under, this Agreement.

(b) Both Parties shall ensure that each of their respective employees and representatives who will have access to the Confidential Information of the Disclosing Party are bound by an agreement to maintain such Confidential Information in accordance with the confidentiality obligations set forth in this Article 12.

(c) Recipient will not use the Disclosing Party’s Confidential Information in any manner whatsoever other than solely in connection with the performance of its obligations, or exercise of its rights, under this Agreement in accordance with the terms and conditions set forth in this Agreement.

(d) Except as permitted by this Article 12, GSK and Santarus each agree not to disclose any terms or conditions of this Agreement or the existence of this Agreement to any Third Party without the prior written consent of the other Party, provided that each Party will be entitled to disclose the terms of this Agreement without such consent to its advisors and potential and existing financing sources, acquirors/acquirees (including to the consultants and advisors of the foregoing), and to others (including in the case of Santarus, to UMissouri and, in the case of GSK, to potential and existing Sublicensees), in each case on a need-to-know basis and on the condition that such Persons agree to keep such Confidential Information in accordance with the obligations set forth in this Article 12. In addition, either Party may disclose the terms of this Agreement to the extent reasonably required by Applicable Law or by applicable rules of any national stock exchange on which the shares of such Party are listed.

(e) In the event Recipient is requested pursuant to, or required by, Applicable Law to disclose any of the Disclosing Party’s Confidential Information, it will notify the Disclosing Party promptly in writing so that the Disclosing Party may seek a protective order or other appropriate remedy or, in the Disclosing Party’s sole discretion, waive compliance with the confidentiality provisions of this Agreement. At the Disclosing Party’s expense, Recipient will co-operate in all reasonable respects, in connection with any reasonable actions to be taken for the foregoing purpose. Recipient may, without liability, disclose the Confidential Information of the other Party to the extent such disclosure is required under Applicable Law, and Recipient will exercise reasonable efforts to obtain reliable assurances that confidential treatment will be accorded to any of the Disclosing Party’s Confidential Information so disclosed.

(f) Upon the effective date of the termination of this Agreement for any reason, either Party may request in writing, and the other Party will either: (i) promptly

destroy all copies of the requesting Party’s Confidential Information in the possession of the other Party and confirm such destruction in writing to the requesting Party; or (ii) promptly deliver to the requesting Party, at the other Party’s expense, all copies of such Confidential Information in the possession of the other Party, provided, however, the other Party will be permitted to retain one (1) copy of the requesting Party’s Confidential Information for the sole purpose of determining any continuing obligations hereunder (or in the case of Santarus, fulfill its obligations under the Missouri Agreement). Additionally, except as otherwise expressly provided herein, upon termination of this Agreement for any reason, both Parties will immediately cease all use of the other Party’s Confidential Information including, to the extent reasonably possible, removing all references to such Confidential Information from its internal analyses, memoranda, compilations, studies or other documents. All Confidential Information will continue to be subject to the terms of this Agreement for the period set forth in this Section 12.1.

Each Party may seek to enforce all rights and legal remedies available under this Article 12 or by law, including injunctive relief, specific performance and other equitable remedies in the event of a breach of the provisions of this Article 12 by the other Party.

(h) Notwithstanding the provisions of this Article 12, the Parties agree that nothing contained in this Article 12 will prevent (i) GSK from disclosing any Santarus Confidential Information, without obtaining Santarus’ prior consent, to any Affiliate of GSK or to any Third Party who has a need to know such Confidential Information for the purposes of engaging in the development, manufacture or commercialization of Licensed Products in the Field in the GSK Territory in accordance with this Agreement; provided that such Affiliate or Third Party is bound by obligations of confidentiality and non-use no less burdensome than those set forth in this Agreement with respect to the Confidential Information, (ii) Santarus from disclosing any GSK Confidential Information, without obtaining GSK’s prior consent, to UMissouri, as required under the Missouri Agreement, or to any Affiliate of Santarus or to any Third Party who has a need to know such Confidential Information for the purposes of engaging in the development, manufacture or commercialization of Licensed Products for sale outside of the GSK Territory; provided that such Affiliate or Third Party is bound by obligations of confidentiality and non-use no less burdensome than those set forth in this Agreement with respect to the Confidential Information or (iii) Santarus from disclosing information or data related to Licensed Products in its filings or submissions to Regulatory Authorities in connection with Licensed Products.

Any key announcements or publicity regarding the existence of this Agreement or any terms or subject matter of this Agreement by either GSK or Santarus will be agreed to by GSK and Santarus in writing in advance of any such announcement or publicity.

The foregoing notwithstanding, the Parties have agreed on a press release to announce the execution of this Agreement in the form attached as Exhibit 12.2, together with a corresponding conference call script and question/answer outline for use in responding to inquiries about this Agreement. Thereafter, GSK and Santarus may each disclose to Third Parties the information contained in such press release and question/answer outline without the need for further approval by the other Party.

In addition, Santarus may terminate this Agreement with respect to any country, upon written notice to GSK effective immediately, if GSK has given written notice pursuant to Section 4.1 that it does not intend to launch or commercialize Licensed Products for applications in the Field in such country.

13.4 Termination Without Cause.

13.4.1 Mutual. The Parties may terminate this Agreement in its entirety at any time and for any reason during the Term upon their mutual written agreement; or

13.4.2 By GSK. GSK may terminate this Agreement in its entirety or with respect to any particular country at any time and for any reason during the Term upon providing Santarus with not less than six (6) months’ prior written notice referencing this Section 13.4.2 and specifying termination of the Agreement in its entirety or the specific country(ies).

13.5 Bankruptcy. Either Party may terminate this Agreement in its entirety at any time during the Term by giving written notice to the other Party if the other Party files in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of its assets, or if the other Party is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition will not be dismissed with sixty (60) days after the filing thereof, or if the other Party proposes or is a party to any dissolution or liquidation, or if the other Party makes an assignment for the benefit of creditors.

13.6 General Effects of Expiration or Termination.

13.6.1 Accrued Obligations. Expiration or termination of this Agreement for any reason shall not release either Party from any obligation or liability which, at the time of such expiration or termination, has already accrued to the other Party or which is attributable to a period prior to such expiration or termination.

13.6.2 Termination of License. Upon termination of this Agreement (but not expiration), all rights and licenses granted to GSK pursuant to Section 2.1 shall concurrently terminate, and Santarus shall thereafter have the right (itself or through Third Parties) to continue the development, manufacture and commercialization of Licensed Products in the Field and GSK Territory without obligation to GSK.

13.6.3 Non-Exclusive Remedy. Notwithstanding anything herein to the contrary but without limiting the last sentence of Section 4.2, termination of this Agreement by a Party shall be without prejudice to other remedies such Party may have at law or equity.

13.6.4 General Survival. Sections 4.6, 4.7, 6.1, 6.2, 7.6, 9.3 and 9.4 and Articles 10, 11, 12, 14 and 15 shall survive expiration or termination of this Agreement for any reason. Additionally, in the event of an expiration of this Agreement in accordance with its terms, but not earlier termination the following shall survive: Sections 2.3, 4.5, 6.3, 8.2 and 8.4. Except as otherwise provided in this Section 13.6.4 or in Section 13.7 or 13.8, all rights and obligations of the Parties under this Agreement shall terminate upon expiration or termination of this Agreement for any reason.

13.6.5 Termination Press Releases. In the event of any termination of this Agreement (whether in its entirety or as to a particular country) for any reason, the Parties shall cooperate in good faith to coordinate public disclosure, if any, of such termination and the reasons

therefor, and shall not, except to the extent required by Applicable Law or the rules of a recognized stock exchange, disclose such information without the prior approval of the other Party, such approval not to be unreasonably withheld, conditioned or delayed. To the extent possible under the situation, the terminating Party shall provide the non-terminating Party with a draft of any such public disclosure it intends to issue five (5) Business Days in advance and with the opportunity to review and comment on such statement, it being understood that if the non-terminating Party does not notify the terminating Party in writing within such five (5) Business Day period (or such shorter period if required by Applicable Law or and the rules of a recognized stock exchange and, in each case as notified to the non-terminating Party in writing) of any reasonable objections, such disclosure shall be deemed approved, and in any event the Parties shall work diligently and reasonably to agree on the text of any such proposed disclosure in an expeditious manner. The principles to be observed in such disclosures shall be accuracy, compliance with Applicable Law and regulatory guidance documents, reasonable sensitivity to potential negative reactions to such news and the need to keep investors and others informed regarding the Parties’ business and other activities. Accordingly in such situation, the non-terminating Party shall not withhold, condition or delay its approval of a proposed disclosure that complies with such principles.

13.7 Effects of Termination by GSK for Certain Material Breaches. Santarus acknowledges that if GSK terminates this Agreement pursuant to Section 13.2 within six (6) months after the Effective Date as a result of Santarus’ uncured material breach with respect to its obligation to make available Data or Regulatory Filings Controlled by Santarus that prevent GSK (itself or through one or more designees) from developing, manufacturing or commercializing the Licensed Products, then GSK may be entitled, as its sole and exclusive remedy, and notwithstanding the reference in Section 7.1 to the up-front payment to Santarus set out in Section 7.1 being non-refundable, to recover damages up to U.S. $11.5 million, the specific amount to be determined pursuant to the procedures set forth in Article 14.

13.8 Effects of Certain Other Terminations. If GSK electively terminates this Agreement in its entirety or with respect to a particular country pursuant to Section 13.4.2, Santarus terminates this Agreement for a particular country in accordance with Section 13.3, either Party terminates this Agreement pursuant to Section 13.2 or either Party terminates for the other Party’s bankruptcy pursuant to Section 13.5, then:

13.8.1 Regulatory Filings. GSK shall promptly assign and transfer to Santarus or its nominee all Regulatory Filings for Licensed Products in the country(ies) affected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety) that are held or controlled by or under authority of GSK or its Affiliates or Sublicensees, and shall take such actions and execute such other instruments, assignments and documents as may be necessary to effect the transfer of rights under the Regulatory Filings to Santarus. GSK shall cause each of its Sublicensees to transfer any such Regulatory Filings to Santarus if this Agreement terminates. If Applicable Law prevents or delays the transfer of ownership of a Regulatory Filing to Santarus, GSK shall grant, and does hereby grant, to Santarus an exclusive and irrevocable right of access and reference to such Regulatory Filing for Licensed Products, and shall cooperate fully to make the benefits of such Regulatory Filings available to Santarus or its designee(s). Within sixty (60) days after written notice of such termination, GSK shall provide to Santarus copies of all such Regulatory Filings, and of all Data and other Know-How pertaining to the Licensed Products not previously

provided. Santarus shall be free to use and disclose such Regulatory Filings and other items in connection with the exercise of its rights and licenses under this Section 13.8. In the event that Santarus does not provide to GSK the identity of its nominee(s) within one (1) year of the effective date of termination, GSK shall have the right to cancel the Regulatory Filings in the relevant country(ies) for which such nominee was not provided.

13.8.2 Technology Licenses. GSK hereby grants Santarus, effective upon the notice of a termination described in this Section 13.8, a non-exclusive, irrevocable, fully paid up license in the country(ies) effected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety), with the right to sublicense, under (a) any GSK IP; provided, however the GSK IP shall not include any Patents or Know-How subject to payment obligations to a Third Party, which GSK shall promptly disclose such obligations to Santarus in writing, unless Santarus agrees in writing to reimburse all amounts owed to such Third Party as a result of Santarus’ exercise of such license, and (b) any Know-How disclosed to Santarus under this Agreement or developed or utilized by GSK in connection with the Licensed Products; in each case to make, have made, use, sell, offer for sale and import Licensed Products.

13.8.3 Trademarks. GSK hereby assigns and shall cause to be assigned to Santarus all rights in and to any trademarks specific to one or more Licensed Products that GSK used with Licensed Product(s) in the country(ies) affected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety). It is understood that such assignment shall not include the name of GSK or any of its Affiliates or trademark for GSK or any Affiliate itself.

13.8.4 Sublicensees. GSK’s sublicenses with respect to Licensed Products shall, at the request of Santarus, be assigned to Santarus to the furthest extent possible in the country(ies) effected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety). In the event Santarus does not request assignment of any such sublicenses, then the rights of such Sublicensees with respect to Licensed Products shall terminate upon termination of GSK’s rights with respect to Licensed Products.

13.8.5 Transition Assistance. GSK agrees to fully cooperate, at its own expense, with Santarus and its designee(s) to facilitate a smooth, orderly and prompt transition of the development, manufacture and commercialization of Licensed Products to Santarus or its designee(s) in the country(ies) effected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety). Without limiting the foregoing, GSK shall promptly provide Santarus copies of customer lists, customer data and other customer information and marketing and promotional materials relating to Licensed Products at GSK’s expense, which Santarus shall have the right to use for any purpose related to Licensed Products. Upon request by Santarus, GSK shall transfer to Santarus some or all quantities of Licensed Products in GSK’s or its Affiliates’ possession (as requested by Santarus) intended for sale in the country(ies) effected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety), within thirty (30) days after the effective date of such termination; provided, however, that Santarus shall reimburse GSK for the out-of-pocket costs that GSK actually incurred to manufacture or otherwise acquire the quantities so provided to Santarus. If any Licensed Product was manufactured by any Third Party for GSK, or GSK had contracts with vendors which contracts are necessary or useful for Santarus to take over responsibility for the Licensed Products in the country(ies) effected by such

termination (or the entire GSK Territory if termination of this Agreement in its entirety), then GSK shall to the extent possible and requested in writing by Santarus, assign all of the relevant Third-Party contracts to Santarus, and in any case, GSK agrees to cooperate with Santarus to ensure uninterrupted supply of Licensed Products. If GSK or its Affiliate or Sublicensee manufactured any Licensed Product at the time of such termination, then GSK (or its Affiliate or Sublicensee) shall continue to provide for manufacturing of such Licensed Product for Santarus, at one hundred thirty percent (130%) of the manufacturing cost therefor, from the date of written notice of such termination until such time as Santarus is able, using Commercially Reasonable Efforts to do so but no longer than twelve (12) months after the effective date of such termination, to secure an acceptable alternative commercial manufacturing source from which sufficient quantities of Licensed Product may be procured and legally sold in the country(ies) effected by such termination (or the entire GSK Territory if termination of this Agreement in its entirety).

13.8.6 Return of Materials. Within fifteen (15) days after the effective date of a termination of this Agreement in its entirety, GSK shall destroy all tangible items comprising, bearing or containing any Confidential Information of Santarus that are in GSK’s or its Affiliates’ possession or control, and provide written certification of such destruction, or prepare such tangible items of Confidential Information for shipment to Santarus, as Santarus may direct, at Santarus’ expense; provided that GSK may retain one copy of such Confidential Information for its legal archives.

ARTICLE 14

DISPUTE RESOLUTION

14.1 Informal Resolution. In the event of any dispute, controversy or claim arising out of, relating to or in connection with any provision of this Agreement or the rights or obligations of the Parties hereunder (a “Dispute”), the Parties will try to settle their differences amicably between themselves as contemplated herein. Either Party may initiate such informal dispute resolution by sending written notice setting forth in reasonable detail the nature of the dispute (the “Dispute Notice”) to the other Party. Within thirty (30) days after such notice, the President of GSK’s International Pharmaceutical business, or his/her designee with authority to resolve such matter, and the Chief Executive Officer of Santarus, or his/her designee with authority to resolve such matter, shall meet to negotiate in good faith a resolution to the dispute within such thirty (30) day period. If such representatives are unable to promptly resolve such disputed matter within the said thirty (30) days, either Party may thereafter initiate arbitration proceedings in accordance with Section 14.2. The provisions of this Section 14.1 will not restrict in any way the Parties’ rights to seek preliminary injunctive or other equitable relief from any court having jurisdiction.

14.2 Arbitration. If a dispute is unresolved following attempted informal dispute resolution pursuant to Section 14.1, then either Party may initiate arbitration before a panel of three (3) arbitrators in accordance with the commercial arbitration rules of the American Arbitration Association (“AAA”) then in force; provided, however, that any dispute related to the infringement, validity or enforcement of any intellectual property right shall be heard by a court of competent jurisdiction in the country where such right exists. The following provisions shall apply with respect to such arbitration:

14.2.1 Arbitrators. Within thirty (30) days after receipt of the notice of arbitration by the Party not initiating such arbitration, each Party shall appoint an arbitrator who is independent of the Parties (which arbitrator shall have reasonable knowledge regarding the pharmaceutical industry), and those two arbitrators shall appoint the third arbitrator within thirty (30) days. In the event that the two (2) arbitrators are unable to agree on a third within the required time, either Party may apply under the applicable rules of the AAA for the appointment of that third arbitrator, and the selection of an arbitrator under such rules of the AAA shall be final and binding on the Parties.

14.2.2 Process. The Parties shall seek to timely appoint their respective arbitrators and to have the full panel of three (3) arbitrators appointed within three (3) months after the non-initiating Party received the notice of arbitration, and seek to conclude the arbitration within nine (9) months after the full arbitration panel has been appointed. The arbitration panel shall determine what discovery will be permitted; provided that the arbitration panel shall permit such discovery as the panel deems necessary to permit a fair resolution of the dispute. The arbitrators shall not order discovery against one Party of a type or nature that is not available against the other Party. The place of arbitration shall be Chicago, Illinois. The arbitration shall be conducted in the English language and all evidence shall be presented in English; provided that any evidence original in a language other than English shall be provided in the original language with a certified translation in English.

14.2.3 Final and Binding. The Parties agree that the award rendered shall be final and binding upon the Parties, and shall be the sole and exclusive remedy with respect to all disputes, controversies, claims and counterclaims presented to the arbitrators (which shall not include any dispute related to the infringement, validity or enforcement of any intellectual property).

14.2.4 Timing. The Parties and the arbitrators shall use all reasonable efforts to complete any such arbitration within one (1) year from the filing of notice of a request for such arbitration unless a Party can demonstrate to the arbitrators that the complexity of the issues or other reasons warrant the extension of the one (1) year period. In such event, the arbitrators may extend such period as reasonably required.

14.2.5 Costs and Fees. The prevailing Party, as determined by the arbitration panel, shall be entitled to recover its reasonable attorneys’ and experts’ fees, and necessary disbursements, incurred in connection with the arbitration, and the non-prevailing Party shall be responsible for reimbursing the other Party for the costs of the arbitration, including administrative and arbitrators’ fees. In the event that neither Party prevails in total, payment of costs and fees shall be made proportionally in accordance with the AAA rules. In determining the appropriate remedy(ies) hereunder, the arbitrators may take into account the number of prior breaches committed by a breaching Party, the number of prior accusations of breaches alleged by the Parties and any prior breaches found to be in bad faith.

14.2.6 Not Public. The arbitration proceedings and the decision shall not be made public without the joint consent of the Parties, and each Party shall maintain the confidentiality of such proceedings and decision unless otherwise permitted by the other Party; provided either Party makes such disclosures as are required to comply with Applicable Law.

14.3 Courts. Nothing in this Agreement shall be deemed as preventing any Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute as necessary to protect any Party’s name, proprietary information, trade secrets, know-how or any other proprietary rights. Judgment upon any arbitration award hereunder may be entered in any court having jurisdiction, or application may be made to such court for judicial acceptance of the award or an order of enforcement, as the case may be. The Parties hereby consent to the jurisdiction of the state and Federal courts in and for Illinois.

ARTICLE 15

15.5.4 Entire Agreement; Amendment; Waiver.

This Agreement may be amended, modified, superseded or cancelled, and any of the terms may be waived, only by a written instrument executed by each Party or, in the case of waiver, by the Party waiving compliance. No waiver by any Party of any condition or of the breach of any term contained in this Agreement, whether by conduct, or otherwise, in any one or more instances, will be deemed to be, or considered as, a further or continuing waiver of any such condition or of the breach of such term or any other term of this Agreement.

15.5.5 No Third Party Beneficiaries. Except as expressly provided in Sections 10.1 and 10.2 (in either case subject to Section 10.3), no Third Party, including any employee of any Party to this Agreement, will have or acquire any rights by reason of this Agreement.

15.5.6 Assignment and Successors. Neither party may assign or transfer its rights under this Agreement or delegate its duties hereunder, by merger, sale of assets, operation of law or otherwise, without the prior written consent of the other; provided, however, that (a) Santarus may assign this Agreement without such consent in connection with the sale or transfer of all or substantially all of its business or assets related to the Licensed Products, and (b) GSK may assign this Agreement without such consent of Santarus to an Affiliate or an entity that is not a Competing Third Party and which acquires all or substantially all of GSK’s pharmaceuticals marketing and distribution business in the GSK Territory, whether by merger, sale of assets or otherwise. Any attempted assignment, sale or transfer in violation of the prior sentence will be void.

15.5.7 Severability. If any provision of this Agreement is or becomes invalid or is ruled invalid by any court of competent jurisdiction or is deemed unenforceable, such provision shall be considered severed from this Agreement, and it is the intention of the Parties that the remainder of the Agreement will not be affected. The Parties will make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one which as closely as possible achieves the objectives contemplated by the Parties when entering this Agreement.
