9.6.4                     Royalties on Combination Products. In the event that a Product is sold as a co-packaged product or in combination with other active, therapeutic components (“Other Product”) for a single price (“Combination Product”), then the royalty payments due on the Net Sales of the Combination Product will be adjusted as follows:

(a)                                 If the Product and the Other Product are sold separately, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the fraction, A/(A+B) where “A” is the mean gross selling price of the Product and “B” is the mean gross selling price of the Other Product.

(b)                                 If the Product and the Other Product are sold separately, but the mean gross selling price of the Other Product cannot be determined, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the fraction A/C wherein “A” is the mean gross selling price of the Product and “C” is the mean gross selling price of the Combination Product.

(c)                                  If the Product and the Other Product are sold separately, but the mean gross selling price of the Product cannot be determined, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the following formula: one (1) minus B/C wherein “B” is the mean gross selling price of the Other Product and “C” is the mean gross selling price of the Combination Product.

(d)                                 If the Product and the Other Product are sold separately, but the mean gross selling price of neither the Product nor the Other Product can be determined, Net Sales of the Product shall be equal to Net Sales of the Product multiplied by a mutually agreed percentage. If the Parties are unable to agree upon such a percentage, the dispute shall be resolved by arbitration pursuant to Section 15.7.

(e)                                  The mean gross selling price for a Product or Other Product shall be calculated for each country, once each calendar year, by dividing the sales amount by the units of the Product (based on BI’s audited records) and/or Other Product (based on data published by IMS or some other mutually agreed upon independent source). In the initial calendar year, a forecasted mean gross selling price shall be used for the Product or Other Product, if no relevant sales occurred in the previous calendar year. Any over or under payment due to a difference between forecasted and actual mean gross selling prices will be paid or credited in the first royalty payment of the following calendar year.

9.6.5                     Royalty Adjustments.

(a)                                 Generic Competition. The royalty payment due to Vitae (as set forth in Section 9.6.1) for sales of a particular Product in a particular country shall be reduced by fifty percent (50%) during any calendar quarter in which such Product faces Generic Competition. “Generic Competition” means and shall be deemed to exist in a particular country in the Territory during a given calendar quarter with respect to a particular Product if during such calendar quarter, one or more Generic Products (other than a Generic Product sold by BI or its Affiliates or by a sublicensee under a license granted by BI or its Affiliate) were sold commercially in such country, and the Generic Products in the aggregate have a market share of twenty-five (25%) or more in that country (as measured by units sold based on data provided by IMS International, or if such data is not available, such other reliable data source as reasonably agreed upon by Vitae and BI). If no data is commercially available, then the Parties shall agree upon a methodology for estimating the percentage unit-based market share of Generic Products in such country.

(b)                                 Co-Development Option. If Vitae exercises its Co-Development Option with respect to a Product pursuant to Section 5.4, Vitae shall be entitled to an increased royalty rate for such Product as follows. The applicable royalty rate from the table in Section 9.6.1 shall be increased by **** per 1% of Phase III Study Development costs shared by Vitae. For example, if Vitae shares in ten percent (10%) of the Development costs for the Phase III Study for such Product, then the applicable royalty rate for each tier shall increase by **** (i.e., a **** royalty rate shall become ****). If Vitae co-funds less than ten percent (10%) of the Development costs for the Phase III Study because actual expenses exceeded BI’s budget forecast by more than ten percent (10%), then Vitae shall still be entitled to an upward adjustment in the applicable royalty rate based on its percentage share of actual Development costs for the Phase III Study (in accordance with the formula set forth in this Section 9.6.5(b)). For example, if Vitae ultimately shares in five percent (5%) of the actual Phase III Study Development costs, then the applicable royalty rate for each tier shall increase by **** (i.e., a **** royalty rate shall become ****).

9.7                               Net Sales Report. Within sixty (60) days following the end of each calendar quarter, BI shall submit to Vitae a written report setting forth Net Sales in the Territory on a country-by-country and Product-by-Product basis during such calendar quarter and year-to-date, total royalty payments due Vitae in respect of Products and Combination Products, and information supporting the calculation of Net Sales of Products (“Net Sales Report”).

9.8                               Third Party Royalties. BI shall be solely responsible for all royalties, milestone payments, fees or other amounts due to any Third Parties with respect to any intellectual property Covering a Product or otherwise necessary or useful for the Development and/or Commercialization of a Product or for conducting the Research Collaboration (“Third Party IP”); except that, BI shall be entitled to deduct from royalties owed to Vitae pursuant to Section 9.6.1 (a) all payments made by BI to any Third Party that are owed pursuant to any license agreement, settlement or award or judgment (including but not limited to damages) with or to a Third Party for Third Party IP (each, a “Third Party Payment”) to the extent such Third Party Payment obligation is based directly on or arises solely as a result of Vitae’s activities conducted prior to the Effective Date in developing or identifying compounds, and (b) fifty

****CERTAIN INFORMATION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION.  CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTION.

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

percent (50%) of any Third Party Payment obligation that is based directly on or arises solely as a result of Vitae’s conduct of the Research Collaboration during the Initial Funded Research Period. In no event shall BI be entitled to reduce (i) the amount of any individual royalty payment owed to Vitae by deducting any payment made to any Third Party in accordance with this Section 9.8 by more than fifty percent (50%), or (ii) the royalties owed to Vitae by the amount of any Third Party Payments for which Vitae indemnifies BI pursuant to Section 12.2. For the sake of clarity, the Parties acknowledge and agree that any Third Party IP claim or Third Party Payment which is based on or arises out of any activities undertaken by the Parties after the Effective Date that infringe or misappropriate the intellectual property rights of Third Parties in connection with the Research, Development or Commercialization of any compounds that were developed or identified by Vitae prior to the Effective Date shall not be deemed to be based on or arise solely as a result of Vitae’s activities for purposes of Section 9.8(a) above.

9.9                               Multiple Royalties. No multiple royalties shall be payable because a Product, its manufacture, use or sale is or shall be Covered by more than one Valid Claim of a Vitae Patent, BI Patent or Joint Patent.

9.10                        Equity Investment. Contemporaneous with the execution of this Agreement, the BI Group shall make an equity investment in Vitae of fifteen million dollars (US$15,000,000) pursuant to an amendment to the Series D Preferred Stock Purchase Agreement by and among Vitae and the BI Group dated as of October 2, 2007, (the “October 2007 SPA”) substantially in the form of the amendment attached as Exhibit 6.

9.11                        Payment Terms.

9.11.1              All sums due to Vitae shall be payable in United States dollars by bank wire transfer in immediately available funds to such bank account(s) as Vitae shall designate.

9.11.2              Except as otherwise set forth herein, all other payments due hereunder shall be paid within thirty (30) days following receipt of Vitae’s invoice.

9.12                        Currency. When Products are sold for monies other than United States dollars, the earned royalties will first be determined in the foreign currency of the country in which such Products were sold and then converted into equivalent United States funds. The exchange rate will be the rate published by the European Central Bank, Frankfurt am Main, Germany, on the last business day of each calendar quarter in which such royalties accrued.

9.13                        Financial Standards. All financial terms and standards (including any calculation of Net Sales, Development costs and financial payments due under this Agreement) shall be governed by and determined in accordance with normally accepted accounting principles (more specifically, the German Handelsgesetzbuch or HGB) and shall be consistent with BI’s audited consolidated financial statements. Notwithstanding the above and notwithstanding the requirements or principles of the HGB, Net Sales shall be calculated in accordance with the formula specified in Section 1.73, and no deductions shall be allowed other than the deductions specifically enumerated in Section 1.73. For avoidance of doubt, there shall be no deduction from Net Sales for bad debt allowances or bad debt expenses.

36

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

9.14                        Late Payments. Any payment that is not paid within two (2) business days of the date such payment is due under this Agreement shall bear interest, to the extent permitted by applicable Law, at an annual rate equal to the one (1) month LIBOR plus two percent (2%) for the first date on which payment was delinquent and calculated on the number of days such payment is overdue.

9.15                        Tax Withholding, Financial Records and Audits.

9.15.1              Tax Withholding. If laws or regulations require BI to withhold any taxes from royalty or advance payments made to Vitae under this Agreement, then such taxes shall be deducted by BI as required by law from such remittable royalty, milestone, FTE or similar payments and shall be paid by BI to the proper tax authorities. Official receipts of payment of any withholding tax shall be secured and sent to Vitae as evidence of such payment. The Parties shall exercise their best efforts to ensure that any withholding taxes imposed are reduced as far as possible under the provisions of any relevant tax treaty.

9.15.2              Financial Records and Audits. BI shall keep accurate and complete records of all financial information needed to calculate Net Sales and/or any payments due to Vitae under this Agreement, including, but not limited to, all such records for the BI Group. BI shall retain records relating to Net Sales and/or any payments made to Vitae during the three (3) preceding calendar years. At Vitae’s request such records shall be made available for inspection, review and audit, during normal business hours and with reasonable advance notice to BI, by an independent certified public accountant, or the local equivalent, appointed by Vitae and reasonably acceptable to BI for the purpose of verifying the accuracy of the BI Group’s accounting reports and payments pursuant to this Agreement and report to Vitae the findings (but not the underlying data) of said examination of records as are necessary to evidence that BI has complied with its payment and other financial obligations under Article 9 of this Agreement. A copy of any report provided to Vitae by the accountant shall be given concurrently to BI. Vitae may perform such an audit no more than once per calendar year. Vitae shall be responsible for all costs and expenses incurred in performing any such audit unless the audit discloses at least a five percent (5%) shortfall, in which case BI shall bear the full cost of the audit. Vitae shall be entitled to recover any shortfall in payments as determined by such audit, plus interest thereon, calculated in accordance with Section 9.14. If said examination of records reveals any overpayment(s) of royalties, then Vitae shall credit the amount overpaid against BI’s future royalty payment(s).

10.                               CONFIDENTIAL INFORMATION.

10.1                        Definition. “Confidential Information” means confidential or proprietary information, data or know-how, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in connection with this Agreement, including, but not limited to, the terms of this Agreement and information relating to the Disclosing Party’s existing or proposed research, development efforts, patent applications, business or products, including, but not limited to BI Know-How, Vitae Know-How and Joint Know-how, as applicable. Confidential Information shall not include any such information that: (i) is already known to the Receiving Party or its Affiliates (other than under an obligation of confidentiality) at the time of disclosure (as evidenced by written records of the

Receiving Party); (ii) is or becomes generally available to the public other than through any act or omission of the Receiving Party or its Affiliates; (iii) is disclosed to the Receiving Party or its Affiliates by a Third Party who had no separate nondisclosure obligation in respect of such information; or (iv) is independently discovered or developed by or on behalf of the Receiving Party or its Affiliates without the use of the Confidential Information of the Disclosing Party (as evidenced by written records of the Receiving Party). The terms of this Agreement shall be deemed Confidential Information of each Party. The Parties agree that with respect to the Vitae Intellectual Property Vitae shall be deemed the Disclosing Party, and with respect to BI Intellectual Property BI shall be deemed the Disclosing Party. With respect to Joint Intellectual Property, both Parties are deemed the Receiving Party.

10.2                        Confidentiality. The Receiving Party shall keep in confidence all Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than in performance of this Agreement or disclose the same to any other Person other than to such of its own and its Affiliates’ employees, agents, sublicensees and subcontractors who have a need to know such Confidential Information to implement the terms of this Agreement. A Receiving Party shall advise any employee, agent, sublicensees and subcontractors who receives Confidential Information of such obligations, and the Receiving Party shall ensure (through enforcement of written agreements or otherwise) that all such employees, agents, sublicensees and subcontractors comply with such obligations as if they had been a Party hereto. The Receiving Party will be liable for breach of this Article 10 by any of its employees, agents, sublicensees and subcontractors.

10.3                        Permitted Disclosure and Use. The Receiving Party shall have the right to disclose Confidential Information if, (i) in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is required by any applicable Laws (including the rules of any stock exchange), provided that the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party and the Receiving Party seeks confidential treatment of such Confidential Information to the maximum extent permitted by the relevant Governmental Authority; or (ii) a court, tribunal, administrative agency or other Governmental Authority orders such disclosure, provided that the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party to permit the Disclosing Party to intervene and to request protective orders or other confidential treatment. The Receiving Party will cooperate reasonably with any such efforts by the Disclosing Party. Furthermore, notwithstanding any other provision of this Agreement, Vitae may disclose Confidential Information as necessary in connection with any financing, merger or similar transaction, subject to confidentiality, or as necessary to obtain legal or financial advice from its attorneys, accountants and legal or financial advisors, provided, however, that Vitae shall limit such disclosure to the extent possible including the provision of redacted documents. The Parties shall also be permitted to make disclosures consistent with, and pursuant to, Sections 15.1 (Publications) and 15.2 (Public Announcements).

10.4                        Return. Upon termination of this Agreement, the Receiving Party shall return or destroy all documents or other media containing Confidential Information of the Disclosing Party with the exception of one (1) copy for the sole purpose of monitoring and documenting the confidentiality obligations hereunder.

38

CONFIDENTIAL TREATMENT REQUESTED

10.5                        Remedies. Money damages will not be an adequate remedy if this Article 10 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, seek an injunction or other equitable relief against such breach or threatened breach without the necessity of posting any bond or surety.

10.6                        Survival. This Article 10 shall survive the expiration or termination of this Agreement for a period of ten (10) years.

10.7                        Internet Mail Encryption. The Parties undertake to protect Confidential Information (including but not limited to patent-related, scientific or technical information) against unauthorized access by Third Parties.

Except as expressly provided in this Agreement and subject to any restrictions therein, each joint owner may make, sell, use, license, assign, mortgage or keep such Joint Inventions, and otherwise undertake all activities a sole owner might undertake with respect to such inventions, discoveries and know-how, with the consent of and without accounting to the other joint owner, provided that (a) such consent shall not be unreasonably withheld, and (b) any such assignment, license or other disposition or use (i) shall at all times be and remain subject to the grants of rights and accompanying conditions and obligations with respect thereto under this Agreement, and (ii) allow the Parties to exercise their rights and perform their obligations under this Agreement, in particular to Research, Develop and Commercialize Products in at least the same scope as prior to such assignment, license or other such disposition. Inventorship for Inventions, including Joint Inventions, shall be determined in accordance with the patent laws of the United States (Title 35, United States Code).

13.1.2              Upon initiation of the first Phase I Study for a Development Candidate pursuant to Section 1.88, such Vitae Patent(s) filed after the Effective Date and which Cover(s) the composition of matter for such Development Candidate shall be jointly owned by the Parties. In addition, Vitae shall provide BI with copies of all related Patent documentation (i.e., all search reports, correspondence with the competent patent offices and other documents relating to the prosecution or maintenance of such Vitae Patents). Vitae shall assign, transfer and convey, also on behalf of its Affiliates, on the condition precedent of initiation of the first Phase I Study (“Assignment Date”) to BI co-ownership rights in such Vitae Patent(s) in all countries, in particular the right to be named and entered into national and regional patent registers as co-owner of said Vitae Patent(s). Vitae shall perform all acts necessary to vest joint ownership in BI in said Vitae Patents, including execution and delivery of all declarations, certificates and other documents, and entry into additional agreements with BI, if necessary. If it is necessary to obtain the consent of a lender to Vitae (the “Lender”) to effect a valid assignment to BI pursuant to this Section 13.1.2 and Vitae determines that it will not be able to obtain such consent from the Lender as of the Assignment Date, then Vitae will do all acts necessary to effect the

44

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

aforementioned assignment, including paying to the Lender the full amount of any outstanding loans made to Vitae, thereby terminating its agreement with the Lender, prior to the Assignment Date. In the event that (i) it is necessary to obtain such consent for the aforementioned purpose and Vitae has not obtained such consent upon Assignment Date, or (ii) Vitae has not performed all necessary acts for giving the effect of the assignment upon Assignment Date at the latest, then BI shall be entitled to make any outstanding payments hereunder directly to the Lender and deduct such amounts from any royalties or milestone payments due hereunder in order to satisfy any outstanding loans of Vitae vis-à-vis the Lender.

(a)                                 Vitae shall inform BI in writing after co-ownership in said Vitae Patents has been established in a valid manner. Upon assignment of said co-ownership rights, such Vitae Patent(s) shall be deemed and treated as Joint Patent(s).

(b)                                 Any costs, expenses or other fees incurred pursuant to this Section 13.1.2, in particular any governmental, notarization, legalization or official fees, for or in connection with the transfer and assignment of the co-ownership rights in said Vitae Patent(s) and the transfer of any related Patent documentation shall be reimbursed by BI within thirty (30) days after receipt of an invoice (detailing value added tax separately) and proper documentation for such fees.

(c)                                  For avoidance of doubt, Vitae shall be required to assign co-ownership rights to only those Vitae Patents which have been filed after the Effective Date and Cover(s) the composition of matter for such Development Candidate. In the event that no Joint Patent Covering the composition of matter for such Development Candidate will be filed after the Effective Date, to the extent legally possible, a divisional, continuation or similar continuing application covering such Development Candidate shall be filed and shall be jointly owned by the Parties. In the event that BI decides to abandon, restrict or otherwise remove any claims in a Vitae Patent assigned to BI, BI shall assist Vitae in filing any divisional, continuation or similar continuing application with respect to such abandoned, restricted or removed claims, as applicable, and any such divisional, continuation or similar continuing application shall be solely owned by Vitae and, if such divisional, continuation or similar continuing application no longer Covers a Development Candidate and BI notifies Vitae in writing that it wishes to exclude such application from the license granted in Section 2.1.1, Vitae shall bear all costs for such application and such application shall not be subject to the license in Section 2.1.1.

13.2                        Prosecution and Maintenance of Patents. During the Term of this Agreement, except as otherwise set forth in this Section 13, Vitae and BI shall closely cooperate in filing, prosecuting and maintaining the Vitae Patents and the Joint Patents using mutually agreed upon Patent Counsel. In the event that an Invention is made solely by one Party and patent filings for such Invention may result in a conflict with actual or intended patent filings of the other Party with respect to the same or a similar Invention, the Parties shall file for a joint Patent covering all aspects of the applicable Invention(s) in accordance with the following procedure: in the event that either Party notifies the other Party in writing that filing a joint Patent is the most appropriate way to avoid conflicting patent filings between the Parties with respect to the applicable Invention(s), then the Parties shall work together to agree on a joint filing for such Patent. If the Parties cannot agree with respect to such joint filing, such disagreement shall be resolved in accordance with the procedure identified in Section 13.2.2. BI

45

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

shall have the right and obligation to file, prosecute and maintain the BI Patents and the BI Product Development Patents. Each Party shall keep the other Party informed as to the status of any Patents Covering the BACE Collaboration Compounds, and shall consult the other Party with respect to major strategic decisions. Upon Vitae’s request BI shall inform Vitae about the status of BI Patents Covering BI BACE Compounds.

13.2.1              Selection of Patent Counsel. Within three (3) months following the Effective Date, the Parties shall agree on a qualified US outside patent counsel (“Patent Counsel”) who shall be engaged by both Parties for filing, prosecuting and maintenance of the Vitae Patents and Joint Patents. The Parties shall also agree in parallel on a substitute Patent Counsel to be engaged only for those cases where, for any reason, the first Patent Counsel is unable to handle a particular patent matter on behalf of Vitae or BI. After the Patent Counsel is selected, Vitae shall within three (3) months instruct its Patent attorneys or agents to promptly transfer all files, including all outstanding office actions and any other significant patent documents relating to existing Vitae Patents to the Patent Counsel. The Patent Counsel shall within two (2) months after having received all files and documents relating to the Vitae Patents arrange for BI to be registered as the exclusive licensee at all patent authorities where such registration is required or legally possible. The Parties shall thereafter ensure that any arising Vitae Patents and any Joint Invention Patents are filed, prosecuted and maintained by Patent Counsel. Vitae and BI shall confer and jointly instruct the Patent Counsel to supervise foreign (i.e., outside of the United States) patent filing, prosecution and maintenance, and shall select (in consultation with Vitae and BI) qualified foreign patent agents in each jurisdiction to file, prosecute and maintain Vitae Patents and Joint Patents in each such jurisdiction. The Patent Counsel shall regularly advise Vitae and BI of the status of all pending Vitae Patent applications and pending Joint Patent applications, including the status of any related hearings or other proceedings, and provide Vitae and BI copies of all documentation concerning such applications and all correspondence to and from any Governmental Authority. BI shall, at its discretion, either use qualified in-house patent counsel or retain qualified outside patent counsel to file, prosecute and maintain BI Patents and BI Product Development Patents. If BI chooses to retain outside patent counsel, it shall have sole discretion to select such patent counsel, except that it may not select a law firm or attorney that has an existing conflict with respect to Vitae. Upon Vitae’s request, BI shall inform Vitae of the status of pending BI Patent applications and pending BI Product Development Patent applications, including the status of any related hearings or other proceedings, and provide Vitae, upon Vitae’s request, copies of all documentation concerning such applications and all correspondence to and from any Governmental Authority with respect to BI Patents.

13.2.2              Decision-Making.

(a)                                 Each Party shall solicit the other Party’s advice and review of BI Patent applications filed after the Effective Date, Vitae Patent applications and Joint Patent applications and important prosecution matters related thereto in reasonably sufficient time prior to filing thereof, and shall take into account the other Party’s reasonable comments; provided that, subject to Sections 13.2.4 and 13.2.5 below and BI’s primary responsibility pursuant to this Section 13.2.2, Vitae shall have the final decision-making authority with respect to any action relating to any Vitae Patent and any Joint Patent, provided that the Parties shall use good faith to agree on any such filing and prosecution matters. If the Parties cannot agree on any such action,

46

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

the Patent Counsel shall be asked for advice, and the Parties shall follow such advice, however, Vitae shall have final decision-making authority with respect to such advise unless BI can show that it would detrimentally affect BI’s interests under this Agreement, in which case such disagreement shall be deemed a Commercial Conflict and resolved in accordance with Section 3.3.4. BI shall have the final decision-making authority with respect to any action relating to any BI Patent and any BI Product Development Patent. However, upon initiation of the first Phase I Study pursuant to Section 1.88, BI shall have primary responsibility for maintaining, prosecuting and defending such Vitae Patent(s) assigned pursuant to Section 13.1.2 and any other Joint Patents that Cover the composition of matter for the respective Development Candidate provided that such activities do not limit the scope or enforceability of said Patents that would be detrimental to the interests of Vitae. If any activities of or on behalf of BI limit the scope or enforceability of said Patents, then Vitae is entitled to veto or require the performance of such activities/decisions, as applicable such that any limit on the scope or enforceability of said Patent does not detrimentally affect the interests of Vitae. Otherwise, BI shall have the final decision-making authority with respect to all activities/decisions not vetoed or otherwise required by Vitae.

(b)                                 Within the first ten (10) months of the priority period, Vitae and BI shall confer about the countries outside the United States in which corresponding applications should be filed (“OUS Filings”). It shall be presumed that a corresponding Patent Cooperation Treaty (“PCT”) application will be filed unless otherwise agreed by the Parties within the first ten (10) months of the priority period. In case a PCT application is filed, the Parties shall consult regarding the countries for which the application should enter into the national phase no later than twenty-six (26) months after the earliest priority date. If the Parties fail to reach agreement about OUS Filings or the country scope for entering the national phase of countries designated in a PCT application, then BI will have final decision-making authority with respect to any BI Patent or any BI Product Development Patent, and Vitae shall have final decision-making authority with respect to any Vitae Patent or Joint Patent, however subject to BI’s primary responsibility under Section 13.2.2(a). If the Party with final decision-making authority declines to file a particular Patent application in a particular country or jurisdiction, then the other Party may exercise its step-in rights (pursuant to Sections 13.2.4 and 13.2.5) by filing such Patent application in such country or jurisdiction at its own expense.

(c)                                  The Parties agree to meet once per year to discuss planned patent activities, filings and budgets. The Parties shall work together in good faith to manage the overall cost of patent activities.

13.2.3              Patent Prosecution and Maintenance Expenses. BI shall be responsible for all costs incurred after the Effective Date in connection with the filing, prosecution or maintenance of Vitae Patents, Joint Patents, BI Patents and BI Product Development Patents, including, but not limited to, (i) filing fees, (ii) attorneys’ fees and other expenses associated with application preparation, prosecution, and maintenance, (iii) all costs associated with reexamination, oppositions and interference proceedings in the United States Patent and Trademark Office and/or the United States Courts, (iv) translation fees, (v) maintenance fees and annuities, including any service fees paid to an annuity payment service provider and (vi) attorneys’ fees and filing fees associated with protest or appeal proceedings. Notwithstanding the foregoing, Vitae shall be responsible for all costs associated with re-

47

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

examination, oppositions, appeals and interference proceedings of Vitae Patents and/or Joint Patents, which are unnecessarily caused by Vitae’s actions.

13.2.4              BI’s Step-In Rights. BI shall have the right, but not the obligation, to assume responsibility for any Vitae Patent or Joint Patent which Vitae intends to abandon or otherwise cause or allow to be forfeited. Vitae shall give BI notice of its intent to abandon a Vitae Patent or Joint Patent in a particular country or jurisdiction within a reasonable period prior to a possible loss of rights, and BI shall thereafter have the right through Patent Counsel, at BI’s sole expense, to prepare, file, prosecute and maintain such Vitae Patents or Joint Patents in such country or jurisdiction.

13.2.5              Vitae’s Step-In Rights. Vitae shall have the right, but not the obligation, to assume responsibility for any BI Patents filed after the Effective Date that BI intends to abandon or otherwise cause or allow to be forfeited. BI shall give Vitae notice of its intent to abandon any Patents assigned to BI pursuant to Section 13.1.2 in a particular country or jurisdiction within a reasonable period prior to a possible loss of rights, and Vitae shall thereafter have the right through Patent Counsel, at Vitae’s sole expense, to prepare, file, prosecute and maintain such BI Patents and/or Patents assigned to BI pursuant to Section 13.1.2 in such country or jurisdiction. Notwithstanding the above, in the event that BI elects not to file, prosecute or maintain a BI Patent or Joint Patent or claims in a BI Patent or Joint Patent that would affect the royalty owed Vitae under this Agreement, BI will reimburse Vitae for all out-of-pocket expenses incurred by Vitae in connection with Vitae’s continued prosecution and maintenance of such Patent.

13.2.6              Execution of Documents by Agents. Each of the Parties shall execute, or have executed by its appropriate agents, such documents as may be necessary to obtain, perfect or maintain any Patent rights filed or to be filed pursuant to this Agreement, and shall cooperate with the other Party so far as reasonably necessary with respect to furnishing all information and data in its possession reasonably necessary to obtain or maintain such Patent rights.

13.2.7              Patent Term Extensions. BI shall have the right but not the obligation to seek extensions of the terms of any Vitae Patents, Joint Patents, BI Patents, BI Product Development Patents and Patents assigned to BI pursuant to Section 13.1.2 Covering a Product. At BI’s request, Vitae either shall authorize BI to act as Vitae’s agent for the purpose of making any application for any extensions of the term of such Patents or shall diligently seek to obtain and maintain such extensions, in either event, at BI’s sole expense. BI shall consult with Vitae prior to its decision to seek a Patent term extension with respect to Vitae Patents, Joint Patents, BI Patents and Patents assigned to BI pursuant to Section 13.1.2, provided, however, that when the Parties hereto cannot reach an agreement for these Patents, BI shall have the right to determine which Vitae Patents, BI Patents, Joint Patents, or BI Product Development Patents to apply for Patent term extension in the Territory. In countries where more than one Patent term extension per Patent owner and per registered Product can be applied for, each Party shall have the right to request Patent term extension. For countries where only one registered Product per Patent can be extended, BI shall have final decision-making authority as to which Product the extension is applied. BI shall be responsible for listing to the “Approved Drug Products with Therapeutic Equivalence Evaluation” (known as the “Orange Book”) in case of United States,

48

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

and any and all similar procedures in the other countries, provided, however, that BI shall consult with Vitae in advance.

13.2.8              Supplementary Protection Certificates. At BI’s request and sole expense, Vitae shall seek to obtain, and maintain until expiry, any SPC’s based on Vitae Patents or Joint Patents, excluding those Patents assigned to BI pursuant to Section 13.1.2, for which BI shall seek to obtain, and maintain such SPCs. Alternatively, at BI’s request and sole expense, Vitae shall authorize BI to obtain SPC’s based on such Vitae Patent or Joint Patent on Vitae’s behalf and provide reasonable assistance and information therefor as well as for the Patents assigned to BI pursuant to Section 13.1.2. Where BI holds the relevant Marketing Authorization, BI shall at its sole discretion provide to Vitae a copy of said Marketing Authorization and any information necessary for the purpose of obtaining an SPC based on such Vitae Patent or Joint Patent. For clarity, BI shall reimburse Vitae for any expenses incurred by Vitae in obtaining an SPC that has been requested by BI. BI shall be responsible, at its sole expense, for obtaining SPC’s based on BI Patents, or BI Product Development Patents and those Patents assigned to BI pursuant to Section 13.1.2.

13.3                        Patent Infringement. With respect to any and all Claims instituted by Third Parties against Vitae or BI or any of their respective Affiliates for patent infringement involving Research, Development, manufacture, use, license, marketing or sale of a Product during the Term (each, a “Patent Infringement Claim”) as applicable, Vitae and BI will assist one another and cooperate in the defense and settlement of such Patent Infringement Claims at the other Party’s request. The Parties agree to respond to or defend against any Patent Infringement Claims as follows:

13.3.1              Without limiting any of BI’s obligations under Section 13.1, and unless Vitae is required to indemnify, defend and hold harmless BI and/or its Affiliate(s) from and against such Patent Infringement Claim pursuant to Section 12.2, BI shall have the primary right to manage the defense of the Parties against a Patent Infringement Claim, at BI’s sole expense. If BI elects to exercise such right as to a Patent Infringement Claim, Vitae shall cooperate with BI at BI’s request and expense, and shall have the right to be represented by counsel selected and paid for by Vitae. If BI elects not to exercise such right as to the Patent Infringement Claim, Vitae may defend such Patent Infringement Claim, at Vitae’s expense, and BI shall cooperate with Vitae at Vitae’s request and shall have the right to be represented by counsel selected and paid for by BI.

13.3.2              The Party managing the defense against a Patent Infringement Claim shall also have the right to settle such Patent Infringement Claim, on terms deemed appropriate by such Party, provided, however that any such settlement must include a full and unconditional release from all liability of the other Party and may not adversely affect the rights of the other Party without such other Party’s prior written consent (such consent not to be unreasonably withheld or delayed). Moreover, any settlement or other Third Party Payment (other than judgments finally awarded by a court) that (i) results in cross-licensing, (ii) results in sublicenses to Third Parties, (iii) otherwise affects the Vitae Patents or Joint Patents, (iv) would have the effect of reducing royalties payable to Vitae under this Agreement or (v) includes any liability or admission on behalf of Vitae, shall be subject to Vitae’s prior written consent, which shall not be unreasonably withheld or delayed.

49

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

13.4                        Infringement of Patents. In the event that Vitae or BI becomes aware of actual or threatened infringement of any Vitae Patents, BI Patents, and/or Joint Patents relating to a Potential Development Candidate, Development Candidate or Product, within the Field during the Term, that Party will promptly notify the other Party in writing. BI will have the primary right, but not the obligation, to bring an infringement action under any Vitae Patents, BI Patents, and/or Joint Patents against any Third Party including the defense against counter-claims of invalidity and unenforceability. If BI elects to pursue such infringement action, BI shall be solely responsible and have the full control of the proceedings and any recoveries (including settlements) will be applied as follows: (i) first to reimburse BI for any expenses incurred in respect of such action; (ii) second to reimburse Vitae for any expenses incurred in respect of such action; and (iii) if the infringement action is brought under any Vitae Patents, BI Patents or Joint Patents, any remaining amounts will be divided equally between the Parties. If BI elects to pursue such infringement action, Vitae may be represented in such action by attorneys of its own choice and at its own expense, with BI having the lead in such action, subject to recovery of such expenses as set forth above. Vitae shall cooperate with and support BI at BI’s request in such infringement procedure. During the Term, in the event that BI does not use Diligent Efforts to pursue such an infringement action, Vitae will be permitted to do so, at Vitae’s sole expense, and, if legally required, in BI’s or the relevant BI Affiliate’s name and on BI’s or the relevant BI Affiliate’s behalf. If BI has consented to an infringement action but Vitae is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then Vitae may join BI as a party-plaintiff. If Vitae elects to pursue such infringement action, BI may be represented in such action by attorneys of its own choice and at its own expense, with Vitae taking the lead in such action. In the event that Vitae brings any such action after BI has elected not to pursue such action, it will retain all recoveries, provided that BI shall be reimbursed its reasonable expenses from such recoveries.

13.5                        Notice of Certification. BI and Vitae each shall immediately give notice to the other of any certification filed under the “U.S. Drug Price Competition and Patent Term Restoration Act of 1984” (or its foreign equivalent) claiming that a Vitae Patent, BI Patent or Joint Patent is invalid or that infringement will not arise from the manufacture, use or sale of a product by a Third Party (e.g., a paragraph IV certification pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(IV)). BI shall have the first option in such proceedings (and similar proceedings in other countries) to take action. Vitae shall cooperate with and support BI, at BI’s request, in such litigation. If BI decides not to bring infringement proceedings against the entity making such a certification, BI will give notice to Vitae of its decision not to bring suit within such time period as to provide Vitae with a reasonable opportunity to retain litigation counsel and file suit within the statutory deadlines, but in no event less than twenty (20) days after receipt of notice of such certification. If BI decides not to bring such infringement proceeding, then Vitae has the right, but not the obligation, to bring suit against the entity that filed the certification. Any suit by Vitae or BI will either be in the name of Vitae or in the name of BI (or any Affiliate) or jointly in the name of Vitae and BI (or any Affiliate), as required by Law.

13.6                        Validity Challenge.

13.6.1              In the event that a Third Party commences any re-examination, interference, opposition or nullity proceeding or challenges the validity or enforceability of, or opposes any extension of or the grant of a patent term extension request or a SPC with respect to,

50

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

any Vitae Patent, BI Patent or Joint Patent (each such action a “Patent Challenge”) during the Term in any country of the Territory, then the Parties shall jointly take such legal action as is required to defend the validity of such particular Vitae Patents, BI Patents, or Joint Patents through patent litigation counsel jointly selected by the Parties. Each Party shall give all reasonable assistance (excluding financial assistance) to the other Party. Each Party may also be represented by counsel of its own selection at its own expense in any such legal action. Any settlement shall be subject to the Parties’ mutual agreement, which shall not be unreasonably withheld or delayed. BI shall be solely responsible for all costs in connection with such Patent Challenge.

13.6.2              For the avoidance of doubt, this Section 13.6 shall not apply to the defense of any Patent Challenge that is raised as a counter-claim or defense by a Third Party that is the subject of an infringement action pursuant to Section 13.3 above, in which case the defense of such Patent Challenge will be governed by such Section 13.3.

13.7                        Assistance. For purposes of this Article 13, the Party not bringing suit shall execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit. The out-of-pocket costs and expenses of the Party bringing suit shall be reimbursed first out of any damages, settlements or other monetary awards recovered. The documented out-of-pocket costs and expenses of the other Party shall then be reimbursed out of any remaining damages, settlements or other monetary awards. The Party initiating and prosecuting the action will retain any remaining damages, settlements or other monetary awards, except as otherwise specified in this Article 13.

13.8                        Settlement. Except as expressly otherwise set forth herein, no settlement, consent judgment or other voluntary final disposition of a suit under this Article 13 may be entered into without the joint written consent of both Parties (each Party’s consent shall not be unreasonably withheld, conditioned or delayed). BI shall not be required to obtain such consent with respect settlement of any disputes involving only BI Product Development Patents.

13.9                        Licensed Patents. The provisions regarding BI Patents under this Article 13 affect those BI Patents which are licensed to BI only to such extent that BI has the right to act under this Section in accordance with the agreement with BI’s licensor. The provisions regarding Vitae Patents under this Article 13 affect those Vitae Patents which are licensed to Vitae only to such extent that Vitae has the right to act under this Section in accordance with the agreement with Vitae’s licensor.

14.                               TERM AND TERMINATION.

14.1                        Term. This Agreement shall commence on the Effective Date and shall end (i) upon the termination of this Agreement pursuant to Sections 14.2 and 14.3; or (ii) upon expiry of the Royalty Term for all Products in all countries (the “Term”). Upon expiry of this Agreement under Section 14.1(ii), BI and its Affiliates shall retain, fully paid-up and perpetually, all licenses granted to BI under this Agreement on a non-exclusive basis.

51

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

14.2                        Termination for Material Breach.

14.2.1              Either Party may, without prejudice to any other remedies available to it at law or in equity, terminate this Agreement in the event that the arbitrator pursuant to Section 15.7 determines that the other Party has materially breached in the performance of its material obligations under this Agreement; provided that the breaching Party shall, (i) if such breach can be cured, have sixty (60) days (ten (10) business days for breach of any payment obligations) after receipt of written notice thereof from the non-breaching Party, such notice containing full details of said breach, to remedy such breach (or, if such breach cannot be cured within such period, the breaching Party must commence and use Diligent Efforts to cure such breach during such period), (ii) if such breach is not capable of being cured, use and continue to use Diligent Efforts to mitigate the impact of such breach, as demonstrated by written evidence, except that the non-breaching Party may nevertheless terminate if such breach is due to willful misconduct or gross negligence. Vitae shall not have the right to terminate the Agreement following the First Commercial Sale of any Product by BI in a Major Market, provided that BI pays Vitae the amount of such damages that have been awarded by the arbitrator pursuant to Section 15.7. Notwithstanding the foregoing or any other provision in this Agreement to the contrary, Vitae shall be entitled to terminate this Agreement for material breach by BI under this Section 14.2.1 (whether such breach occurred before or after First Commercial Sale of a Product) in the event that the arbitrator pursuant to Section 15.7 has determined that BI has willfully breached its obligation to pay the royalties as set forth in Sections 9.6 and 9.8 or any milestone payments as set forth in Sections 9.3 and 9.4. BI shall not have the right to terminate the Agreement hereunder following the First Commercial Sale of any Product in Major Market by Vitae provided that Vitae pays BI the amount of such damages that have been awarded by the arbitrator pursuant to Section 15.7.

14.2.2              Any such termination shall become effective at the end of such sixty (60) day period unless the breaching Party has cured any such breach prior to the expiration of such sixty (60) day period (or, if such breach is capable of being cured but cannot be cured within such sixty (60) day period, the breaching Party has commenced and used Diligent Efforts to cure such breach, provided that, in such instance, such cure must have occurred within one hundred twenty (120) days after receipt of written notice thereof from the non-breaching Party).

14.2.3              After the First Commercial Sale of any Product by the BI Group or its sublicensees in a Major Market, except as provided for in Section 14.2.1, Vitae shall not have the right to terminate this Agreement in the event that the arbitrator determines that BI failed to use Diligent Efforts in connection with its performance of this Agreement, provided that BI pays Vitae the amount of Special Damages. “Special Damages” means the amount of damages incurred or suffered by Vitae which shall include an amount equal to the milestone payments and royalties payable on Net Sales that the arbitrator determines BI could have achieved if it had used Diligent Efforts.

14.2.4              For the avoidance of doubt, Vitae may only terminate this Agreement for BI’s (alleged) failure to use Diligent Efforts under Section 14.2.3 or 14.3.3 under the terms set forth therein and not under Section 14.2.1.

52

CONFIDENTIAL TREATMENT REQUESTED

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

14.3                        Other Termination Rights.

14.3.1              BI shall have the right to terminate this Agreement on the first anniversary of the Effective Date by providing written notice ninety (90) days’ prior to such first anniversary date, provided that BI shall pay Vitae the balance of the amount of the committed research funding payments for the first two years of the Initial Funded Research Period as set forth in Section 9.2.1 not paid by BI prior to such termination. For avoidance of doubt, the total amount of the committed research funding payments for the first two years is eight million, one hundred and sixty thousand dollars (US$8,160,000). In addition, BI shall be responsible for all previously authorized out-of-pocket expenses incurred or committed on or before the effective termination date.

14.3.2              At any time after the Research Term, BI shall have the right to terminate the entire Agreement or to terminate Development or Commercialization on a Product-by-Product basis upon ninety (90) days’ written notice to Vitae. Any such Product (containing a BACE Collaboration Compound and/or a BI BACE Compound that has been selected as a Development Candidate) that is thereby terminated shall be referred to as a “Terminated Product.” If BI terminates the entire Agreement for any reason, then all Potential Development Candidates, Development Candidates and BACE Collaboration Compounds shall be deemed Terminated Products.

14.3.3              Vitae may terminate this Agreement before the First Commercial Sale of a Product in a Major Market on a Product-by-Product or compound-by-compound basis or in its entirety if a Commercial Conflict pursuant to Section 1.23(i) is resolved pursuant to Section 15.7 in favor of Vitae, and BI has not cured such Commercial Conflict within one hundred and twenty (120) days upon such arbitrator’s final decision. Any such Product or compound shall be deemed to be a Terminated Product, but the Agreement will otherwise continue in effect.

14.4                        Effects of Termination; Terminated Products.

14.4.1              Effect of Termination.

(a)                                 Termination for Material Breach by Vitae. In the event that this Agreement is terminated by BI pursuant to Section 14.2 for material breach by Vitae:

(i)                                     Vitae shall retain its rights granted by BI under Section 2.1.2(a)(ii) and 2.1.2(b)(ii) with the respective sublicense rights under 2.2.2.

(ii)                                  All licenses granted by Vitae to BI or its Affiliates under this Agreement will survive, subject to BI’s and its Affiliates’ ongoing obligations to pay milestone payments and royalty payments to Vitae hereunder; however, in case of an uncured Serious Material Breach resulting in BI’s loss of exclusivity in either the US market or in all five (5) of the Major EU Countries (as evidenced by BI Product(s) facing Generic Competition in those markets), BI shall be released from making any further royalty or milestone payments to Vitae for the Product(s) with respect to which the Serious Material Breach relate. In any other case of an uncured Serious Material Breach, the arbitrator, pursuant to Section 15.7, shall determine the deduction from any milestone and royalty payments by BI (for the Product(s) with

53

public offering of any Vitae stock). Notwithstanding the foregoing, in the event that a controlling majority of the voting stock of Vitae is acquired by an entity during or after an initial public offering, then this shall be defined as a Transaction.

(a)                                 In the event of a Transaction wherein the entity acquiring the assets or capital stock of Vitae (hereinafter, such entity and all of its current and future Affiliates (excluding Vitae and its controlled Affiliates) shall be collectively referred to as an “Acquiring Entity”) is a pharmaceutical company marketing an Alzheimer’s Disease or other dementia-related product or having an Alzheimer’s Disease or other dementia-related research program, (i) the Parties shall in any event retain all rights granted in this Agreement, in particular under Article 2; and (ii) BI shall be released from its obligations under Articles 3, 4, 5, 6, 7 and Sections 8.1, 8.2, 8.4 of this Agreement, provided, however, that BI shall continue to be obligated to use Diligent Efforts to Develop and Commercialize Products following any Transaction; and (iii) all other provisions of the Agreement shall continue in full force and effect. Notwithstanding the foregoing, in the event that Vitae has exercised and fully funded its Co-Development Option pursuant to Section 5.4 prior to the consummation of the Transaction or issuance of a press release about the Transaction, whatever occurs earlier, then Vitae shall be entitled to the increased royalty rate as set forth in Section 9.6.5(b).

(b)                                 Furthermore, in the event of a Transaction, the Parties understand and agree that any intellectual property, in particular, any Patents, know-how and compounds of such Acquiring Entity need not be introduced into this collaboration by Vitae and shall not be considered Vitae Intellectual Property or Joint Intellectual Property. Therefore, this collaboration will not extend to such intellectual property, in particular any Patents, know-how and compounds; and BI shall not, by virtues of said Transaction, obtain a license to the intellectual property of such Acquiring Entity.

14.6                        Accrued Rights; Surviving Obligations. Except as provided elsewhere, termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration.

14.7                        Bankruptcy under U.S. or German Law. If this Agreement is rejected by or on behalf of Vitae under Section 365 of the United States Bankruptcy Code (the “Bankruptcy Code”), all licenses and rights to licenses granted under or pursuant to this Agreement by Vitae to BI are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code. For the avoidance of doubt, the Parties intend that the licenses granted by Vitae to BI under this Agreement, in particular pursuant to Section 2.1 of this Agreement, are licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code. The Parties agree that BI, as a licensee of such rights under this Agreement, shall retain

BACE RESEARCH COLLABORATION AND LICENSE AGREEMENT

and may fully exercise all of its rights and elections under the Bankruptcy Code, and that upon rejection of this Agreement by Vitae in a case under the Bankruptcy Code, if BI elects to retain its rights, as provided in Section 365(n)(1)(B) of the Bankruptcy Code, Vitae, as debtor in possession, or any trustee appointed in a case filed by or against Vitae under the Bankruptcy Code, shall provide to BI all intellectual property licensed to BI under this Agreement (including any embodiments) and held by Vitae or any trustee of Vitae, as provided in Section 365(n)(3)(A) of the Bankruptcy Code. If this Agreement is rejected by or on behalf of BI in the event that (a) BI becomes a debtor in a bankruptcy proceeding or other proceeding for the general settlement of its debts, (b) a receiver or other official is appointed for all or substantially all of BI’s assets, or (c) BI makes a general assignment for the benefit of creditors, then Vitae will be entitled, to the extent legally possible under German Law, to receive the benefit of any protections afforded to licensees of intellectual property under German bankruptcy law, including protections equivalent to those provided under Section 365(n) of the Bankruptcy Code, whether such protections are in existence as of the Effective Date or are enacted in the future.

15.                               MISCELLANEOUS.

15.1                        Publications. Prior to the commencement of the first Phase I Study in respect of any Development Candidate, neither Party shall make any publication in respect of the results arising out of Research and Development without prior written consent of the other Party. Any publication made after commencement of the first Phase I Study in respect of a Development Candidate or related Product shall be made in accordance with a publication strategy and the following provisions of this Section 15.1. BI shall be responsible for the development of a publication strategy regarding the Development Candidate and/or Product. The publication strategy shall be presented to the JSC no later than the start of the Phase I Study for said Developmental Candidate and/or related Product. The JSC shall be notified of any planned abstracts, oral presentations and manuscripts relating to the publication of clinical data and other scientific data generated in the course of Development of the relevant Product by the submitting Party. The JSC shall discuss whether a planned submission might contain information which compromises the patentability or confidentiality of Vitae Intellectual Property, BI Intellectual Property, BI Product Development Intellectual Property, or Joint Intellectual Property. In the event that said patentability or confidentiality would be compromised, the Party wishing to publish shall within fourteen (14) days of objection by the other Party, request in writing a review of the abstract, oral presentation or manuscript for protection of patentable or proprietary information. If requested in writing by the other Party, the submitting Party shall provide a draft of the planned submission and withhold the material for publication or presentation for forty-five (45) days to allow for the filing of patent applications or the taking of such measures as may be appropriate to preserve proprietary rights in and the confidentiality of the information in the material being submitted for publication or presentation (including withholding such publication). The review period may be extended for an additional sixty (60) days if a representative of the JSC can demonstrate a reasonable need for such extension, including, but not limited to, the preparation and filing of Patent applications. By mutual agreement of the Parties, this period may be further extended. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any such publications or presentations.

No employee or representative of a Party shall have any authority to bind or obligate the other Party to this Agreement in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, the Parties’ legal relationship under this Agreement to each other shall be that of independent contractor. This Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

15.5                        Registration of This Agreement.

The Party subject to a Force Majeure Event shall promptly notify the other Party of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected shall use Diligent Efforts to avoid or remove such causes of non-performance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall without delay recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 15.6.

EXHIBIT 2

PRELIMINARY RESEARCH PLAN

Preliminary Research Plan BACE Inhibitor Project

The aim of this project is to identify BACE inhibitors which lower amyloid b-peptide (Ab) production in the CNS. Based on experiences and published data with BACE or gamma-secretase inhibitors, we expect that — in an acute study design — an Ab reduction in the **** should be of therapeutic benefit. In APP-transgenic animal models, this is measured as a reduction of the amyloid plaque load in chronic prevention studies.

The high-level work plan shown in the schematic below will be continuously updated in the course of the project, continuously integrating the progress made. The project team will be responsible for data review and prioritization of program activities on a weekly basis.

The intent of the defined labor allocation is to tailor current lead optimization strategies to the actual status of the respective compound series. Both parties will continue the optimization of the current two lead series identified at Vitae and will position the back-up classes accordingly. Timing and location of co-crystallisation (and soaking) work will be agreed between the parties. **** The compounds will additionally be profiled in vitro with regard to their potency on the enzyme level, for which a BACE assay is available at BI. Another enzymatic assay that could ideally be used at both sites is currently developed by BI (availability not yet confirmed). Representative compounds will be tested at BI for their potency on primary neurons (BI assay format). All in vivo pharmacology studies will be performed at BI. **** These optimization parameters are reflected in the DDS profiling scheme. DDS profiling is foreseen to be primarily conducted at BI. In general, decision-relevant in vitro PK assays will precede the in vivo PK studies. Due to the time-consuming prevention study in the transgenic mice (7-8 months), we expect that — if the acute efficacy of the compound plus the other criteria for SoPD is reached — this study will be initiated during the candidate selection phase, i.e. not be done before SoPD, but before SoD.
