Regeneron may terminate the Joint Discovery Research Term with at least *** days' notice prior to the beginning of the sixth Year or any Year thereafter. (d) If a Research Compound is identified by either or both Parties (x) during the Joint Discovery Research Term but has not been designated a Development Compound prior to termination of the Joint Discovery Research Term, or (y) during the Tail Period, the Parties shall meet within *** days of the termination of the Joint Discovery Research Term in the case of (x) or within *** days of such identification in the case of (y) to agree on a Research Plan or other disposition (e.g., license to a Party or Third Party) of such Research Compound. All funding for the Research Plan during the Joint Non-discovery Research Term shall be shared equally by the Parties. The Joint Non-discovery Research Term shall be terminated by the JMC's designation of such Research Compound as a Development Compound, or as otherwise agreed by the Parties. 3.3. Selection of Development Compounds. (a) At the time that the Parties have performed sufficient research and preclinical testing of a Research Compound and such testing shows that the Research Compound may have utility in the Field and has met the Research Plan's predetermined Success Criteria for such Research Compound to be considered a Development Compound, so that the JMC reasonably determines that the Research Compound should undergo safety assessment and other preclinical development activities to determine whether to commence clinical studies with respect thereto (and thereby such Research Compound being designated as a Development Compound), then further research, development, and commercialization of the Development Compound will be conducted in accordance with this Agreement. *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. (b) If the JMC agrees that the Research Compound meets the Success Criteria but one Party elects to opt out of further development, then the Party desiring not to proceed in developing the Research Compound shall be deemed an Opting Out Party with respect to that Research Compound. The Proceeding Party may develop the Research Compound only if such Research Compound would not be a Competing Product with respect to other existing Development Compounds and Marketed Compounds. (c) Within *** after the designation of a Development Compound by the JMC, the Parties shall meet and agree as to how such Development Compound will be developed and commercialized and incorporate such agreements into the Product Plan. The Product Plan shall include general goals of the Parties relating to the development and commercialization of each Development Compound and the timing, nature, and priority of resources to be applied and will detail tasks and goals, personnel allocation, outside services and costs, Success Criteria, Allowable Expenses, budgets, and such other matters deemed necessary to implement the Product Plan. The Product Plan will include a spending forecast through the end of clinical trials for the Development Compound and a budget for the next Fiscal Year that will be updated by the JMC at least annually on a Fiscal Year basis. Procter & Gamble is responsible for taking the lead in proposing such budget with significant and timely input from Regeneron. The timing and calculations for the typical Product Plan budget is contained in Attachment 3.1 as an example. The JMC will have complete authority to adopt all Product Plans. 3.4. Funding of Development Compounds and Marketed Compounds; Opting Out. (a) All Allowable Expenses for a Development Compound incurred pursuant to the Product Plan by either Party will be shared equally by the Parties, whether the JMC designated the Development Compound as such prior to or after the end of Year 3. Nothing herein shall excuse or mitigate Procter & Gamble's funding obligations under Section 3.2. (b) During the development of a Compound, if one Party is unable to fund its equal share of Allowable Expenses (the "Owing Party") and proceeds in good faith to pursue financing for its share from a Third Party, such sum shall be loaned to the Owing Party by the other Party, accruing interest at the rate specified in Section 6.4, for a period not to exceed*** from the time the funding for such Allowable Expenses was initially due ("Advances"). If the Owing Party fails to timely repay the Advances along with any other Allowable Expenses that may be payable at that time, the Owing Party shall be deemed to be an Opting Out Party as of the *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. date such Advances were initially due. Advances for each Party shall be limited to *** Advances per Compound and no more than *** Advances for all Compounds during the same *** period. An example relating to Advances is outlined in Attachment 3.4(b). (c) If, at any time during a Compound's development or commercialization, one Party, but not both, elects not to participate in the further development and/or commercialization of such Compound, then such Party shall be deemed an Opting Out Party with respect to that Compound, either in total or on a country-by-country basis pursuant to Section 3.6. At that point, the Proceeding Party may proceed to develop and/or commercialize such Compound at its own expense. Unless the Parties otherwise agree, in no event, however, may a Party opt out from or otherwise refuse to pay its share of Allowable Expenses to which such Party has committed. (d) If both Parties opt out, the Parties shall use Commercially Reasonable Efforts to license the Compound, and each Party's respective share of any income derived from such Compound shall be calculated pursuant to Section 6.1(b). (e) The Parties' equal funding of Allowable Expenses under the Product Plan shall commence on the day the JMC designates the Development Compound as such and be payable quarterly in arrears, based on justification of Allowable Expenses incurred over the quarter. Regeneron and Procter & Gamble shall submit reports to each other within thirty (30) days of the end of each Calendar Quarter detailing the number of FTEs performing research and development activities pursuant to the Product Plan, Third Party costs and other costs incurred in research, development and commercialization activities, as well as a detailed description of such activities. Each Party shall review and approve the other Party's reports within fifteen (15) days thereafter, subject to the JMC's approval, if necessary. Procter & Gamble will then calculate the amount that shall be paid by either Party to the other Party to equalize funding and so advise Regeneron within seven (7) days. The Party to whom funds are owed will issue an invoice for the corresponding amount, payable within thirty (30) days. Costs incurred and paid pursuant to this Section are subject to audit pursuant to Section 6.5. 3.5. Research, Development and Commercialization Communication. In addition to Regeneron's reporting obligations under Section 3.2(b), Regeneron and Procter & Gamble will submit reports to each other not less than two (2) times per Fiscal Year presenting a meaningful summary of research, development and commercialization activities performed under this Agreement. Regeneron and Procter & Gamble will make presentations of such activities to each *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. other, beyond that made to the JMC, as reasonably requested by each other. All Technology generated by the Parties shall be disclosed pursuant to Section 7.1. Subject to Section 5.4, the Parties shall use their best efforts to communicate information only in the Field. Regeneron and Procter & Gamble will also communicate informally and through the JMC to inform each other of research and development done under this Agreement. Regeneron and Procter & Gamble will provide each other with raw data in original form or a photocopy thereof for any and all work carried out under this Agreement as reasonably requested by the other. Any information contained in such reports and as otherwise communicated by Regeneron or Procter & Gamble is subject to Article VIII. If one Party is deemed an Opting Out Party, the Proceeding Party shall annually report to the Opting Out Party research, development and commercialization activities performed for Compounds in the Territory for the prior Year sufficient to allow the Opting Out Party to determine whether the Proceeding Party is utilizing Commercially Reasonable Efforts. 3.6. Global Development. The Product Plan shall set forth commercially reasonable development work (including without limitation clinical studies) to support acceptable regulatory applications for marketing clearance in all Major Countries. The costs associated with these activities shall be deemed "Global Expenses". If either Party fails to pay its share of Global Expenses with respect to a Compound, such Party shall be deemed an Opting Out Party with respect to such Compound in the entire Territory. Either Party may opt out of the commercialization of a Compound on a country-by-country basis provided it funds its share of total Global Expenses, to the extent that funding of any development and/or commercialization expenses is solely attributable to one country and is not considered a Global Expense ("Country Expenses"). A Party electing to opt out of such Country Expenses shall be deemed an Opting Out Party with respect to such Compound in that particular country only. 3.7. J-V Formation. Commencing at the end of the first Year, the Parties shall negotiate in good faith an agreement by the end of the third Year that contains all of the terms and conditions of this Agreement, along with other terms and conditions as the Parties may agree to develop and/or commercialize Compounds ("J-V Agreement"). In the event that the Parties cannot finalize such J-V Agreement prior to the end of the third Year, Procter & Gamble may terminate this Agreement pursuant to Section 3.2(c), elect to continue to perform research, development and commercialization activities pursuant to this Agreement until its termination, or negotiate such other arrangement as the Parties may agree. 3.8. Sumitomo Compounds. (a) *** (b) *** Article IV - Commercialization of Products 4.1. Marketing and Sales Strategy. ***. 4.2. Net Profits. The Parties, so long as neither Party is an Opting Out Party with respect to such Marketed Compound either in the entire Territory or in one or more specific countries, as appropriate, will share equally in the Net Profits of each Compound sold. "Net Profits" mean Net Sales less Allowable Expenses. 4.3. Exclusive Distributor. The JMC may appoint either Party or a Third Party to act as its agent in connection with the marketing, sale and distribution of Marketed Compounds, and the JMC and/or the Parties (as the case may be) shall grant to such agent(s) appropriate authority to perform its or their responsibilities hereunder. In connection with such marketing, sales and distribution, the following principles shall apply: (a) the business objective will be to maximize overall profits; and (b) in the event that a Third Party is appointed as the Parties' agent with respect to the marketing, sale and distribution of the Marketed Compound in a country, Regeneron and Procter & Gamble will each receive equal shares of any revenue received from such Third Party, so long as neither Party is an Opting Out Party with respect to such Marketed Compound in such country. 4.4. Regeneron Co-Promotion Activities. Provided that Regeneron is not an Opting Out Party with respect to the Compound, Regeneron will have an equal right and opportunity, but not the obligation, to participate in the sales and marketing efforts in any country in the Territory as to which it has not opted out by supplying up to fifty percent (50%) of a Marketed Compound's sales and marketing efforts with notice to Procter & Gamble within *** of the JMC's decision to prepare a regulatory application for marketing clearance in the first Major Country with respect to all Major Countries, then on a country-by-country basis upon regulatory *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. filings in such countries other than Major Countries. Regeneron's and Procter & Gamble's sales and marketing personnel costs shall be an Allowable Expense and shall be calculated for both Parties on the same basis (e.g., the cost per salesperson or sales call for Regeneron and Procter & Gamble shall be the same per year). If Regeneron wants to discontinue or decrease its co-promotion activities, it must give Procter & Gamble *** months' notice prior to such discontinuation or decrease. 4.5. Trademarks; Packaging. After a Compound has been designated a Development Compound, the Parties shall jointly develop a trademark for such Development Compound. So long as it is not an Opting Out Party with respect to such Compound in a country, Procter & Gamble shall file, prosecute and maintain all trademark applications and registrations for such trademarks, and all expenses in connection with such activities shall be deemed Allowable Expenses. As long as neither Party is an Opting Out Party with respect to the Marketed Compound, such Marketed Compound shall be sold under a single trademark which shall be owned by Procter & Gamble or, if a legal entity is formed pursuant to a J-V Agreement, the trademark shall be owned by such entity to the extent legally permissible. If one Party is an Opting Out Party with respect to such Marketed Compound, any trademarks shall be owned by the Proceeding Party. So long as neither Party is an Opting Out Party, the label of the Marketed Compound will contain the name of Regeneron and Procter & Gamble, to the extent legally permissible.

Article VI - Royalties and Accounting 6.1. Royalty Calculation. (a) The Proceeding Party will pay to the Opting Out Party a royalty on Net Sales of a Marketed Compound on a country-by-country basis, sold by the Proceeding Party, its Affiliates, licensees and/or sublicensees in the Territory at the applicable rate listed below multiplied by the Net Sales in such country: *** *** --------- ------- *** *** *** *** *** *** *** *** Such royalty will be paid for a period of *** years from the date of first sale to a customer of such Compound in a particular country, or for so long as the manufacture, use, importation or sale of the Compound would, but for the licenses granted herein, infringe a Valid Claim of a Patent in such country, whichever is longer. (b) If both Parties opt out with respect to a Compound in total or on a country-by-country basis, opting out either simultaneously or sequentially, then the Parties shall use Commercially Reasonable Efforts and cooperate with each other to license the Compound to a Third Party. ***. Examples of the respective percentages are outlined in Attachment 6.1(b). Reasonable out-of-pocket expenses incurred in obtaining such licensee shall be shared equally by the Parties. Notwithstanding the above, either Party may receive, without sharing with the other Party, reimbursement from such licensee for reasonable, (*** to account for indirect overhead) costs of research, development and/or commercialization costs (whether internal or Third Party) to be incurred by such Party for work to be conducted in the future on behalf of the licensee. Any amounts in excess of such reimbursement shall be shared in the same proportion as calculated above in this Section 6.1(b) All amounts from licensees received by either Party shall be fully disclosed to the other Party and subject to audit (including without limitation the calculation of Fully-Loaded costs) pursuant to Section 6.5.

Compound to avoid a non-frivolous claim of patent infringement, the Proceeding Party shall offset the following portion of the Third Party license fee, royalty or other similar payments ("Licensee Fees") against the Opting Out Party's royalty: *** *** --------- ------- *** *** *** *** *** *** *** *** Any portion of Licensee Fees paid by the Proceeding Party that is to be offset against the Opting Out Party's royalty but that exceeds the Opting Out Party's royalty payable, shall be carried forward and accrue interest pursuant to Section 6.4 and be offset against future royalties as such royalties become payable. 6.2. Royalty Payment. (a) Royalties payable under Section 6.1 will be paid not later than sixty (60) calendar days following the end of each Calendar Quarter. All payments shall be accompanied by a report in writing showing the Calendar Quarter for which such payment applies, the amount billed to Third Parties for Marketed Compounds sold during such Calendar Quarter, the deductions from the amount billed to arrive at the Net Sales, the Net Sales for the Calendar Quarter, and the royalties due on such Net Sales, such report being broken down by Marketed Compound and country. All royalties will be paid in the currency where Net Sales take place or, at the option of the payee, in US dollars at a rate of exchange on the last business day of the Calendar Quarter as quoted in The Wall Street Journal (or Citibank, N.A. if such rates are not available in The Wall Street Journal). (b) All royalties due under this Article VI will be deposited in a bank chosen by the recipient by the date due. Any amounts or royalties prohibited from export by a particular country will be deposited in a bank chosen by the recipient in such country. Any deductions for withholding taxes imposed by the country in which Net Sales take place will be withheld and *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. paid as required by law.

Audit. Records shall be open for audit during reasonable business hours for a period of three (3) years from creation of individual records for examination not more often than once each year by an independent certified public accountant ("CPA") selected by the payee and reasonably acceptable to the payer for the sole purpose of verifying the correctness of payments to be made under this Agreement. If the CPA finds a discrepancy of greater than ten (10) percent of such payment, the CPA shall submit a detailed report regarding the audit and such discrepancy to both Parties within thirty (30) days of commencing the audit. The Parties shall attempt to resolve such discrepancy to their mutual satisfaction during the next fifteen (15) days. If the Parties cannot resolve the discrepancy, their CEOs shall meet within ten (10) days after such fifteen (15) day time period. If the CEOs cannot resolve the dispute within five (5) days, either Party may take such dispute to arbitration pursuant to Section 11.4. The calculation of such payment shall be deemed final (and not subject to audit or dispute resolution) five (5) years after the period in which such payment was due, unless arbitration pursuant to Section 11.4 is commenced prior to such time. Out-of-pocket expenses incurred with respect to such CPA shall be paid by the payee; however, the payer shall reimburse the payee for such CPA expenses if the discrepancy is greater than ten (10%) percent, as such discrepancy is determined by the CEOs or arbitrators.

(b) Indemnification by the Parties. Each Party shall indemnify and hold the other Party harmless from and against that portion of any and all Losses due to the gross negligence or willful or intentional misconduct of such indemnifying Party, as well as any Losses that were not caused by Joint Activities. (c) Indemnification by the Proceeding Party. The Proceeding Party agrees to save, defend and hold the Opting Out Party harmless from and against any and all Losses to the extent that such factual allegations forming the primary basis for such Losses occurred after the Party became an Opting Out Party with respect to that Compound and/or country. Both Parties shall provide prompt notice to the other of such potential Losses. The Proceeding Party shall assume control of the defense of the potential Losses (including without limitation the right to settle the claim). The Opting Out Party shall provide reasonable cooperation to the Proceeding Party, and the Proceeding Party shall reimburse the Opting Out Party its reasonable out-of-pocket expenses. (d) Indemnification Procedure. In the event that either Party receives notice of potential Losses, such Party shall immediately inform the other Party and the JMC. The JMC shall decide the manner in which to respond to and handle the claim. If the JMC cannot decide on how to respond to the claim prior to five (5) days before the answer is due, the Party receiving the notice shall answer the claim and take reasonably necessary actions to defend itself, and the other Party may appoint its own counsel at its own expense, until the JMC agrees on how to handle the claim. Article X - Term, Termination 10.1. Term. Unless terminated earlier pursuant to Sections 3.2, 10.2 or by mutual agreement, this Agreement shall expire at the end of the Royalty Term. 10.2. Default. Failure by either Party (the "Defaulting Party") to comply with any of the material obligations contained in this Agreement, the Stock Purchase Agreement, the Stock Registration Agreement or any J-V Agreement shall entitle the other Party (the "Nondefaulting Party") to give to the Defaulting Party notice specifying the nature of the default and requiring it to cure such default. If the Defaulting Party disagrees with the existence, extent or nature of the default, the Parties shall use good faith efforts to resolve the dispute within thirty (30) days. If (i) such default is not cured with such thirty (30) day period after the receipt of such notice or (ii) the Parties have not otherwise resolved the dispute during such thirty (30) day period, the Nondefaulting Party shall be entitled to initiate arbitration under Section 11.4 and at its sole discretion suspend performance under this Agreement. 10.3.

Upon receipt of any such notification, the other Party or an Affiliate thereof (the "Electing Company") shall have the unilateral right to give notice to the Acquired Company within *** days after its next regularly scheduled board meeting, but in no event longer than *** days, after receipt of the Acquired Company's notification that the Electing Company: (i) elects not to continue the research, development and commercialization collaboration, whether or not a J-V has been formed (the "Option"), in which case a determination of the License Fee pursuant to Section 10.6 will be made, and within *** *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. following such License Fee determination will make the further election either to purchase the entire interest of the Party affiliated with the Acquired Company under this Agreement or any J-V Agreement ("Acquired Company Interest") or offer the Acquired Company the option to purchase the entire interest of the Electing Company under this Agreement or any J-V Agreement ("Electing Company Interest") at the License Fee (but in the event that the Acquired Company does not desire to purchase the Electing Company Interest, the interests of the Parties shall be disposed of by sale, license, or other commercially reasonable arrangement for a price that maximizes value for both Parties, paid by a Third Party or a Party, and each Party shall have the right to receive half of the consideration thus obtained less any Advances plus accrued interest payable), or (ii) desires to continue the collaboration for a period of up to *** from the date of the Change in Control (the "Trial Period") upon the express condition that the ultimate parent of the entity acquiring control of the Acquired Company within *** days thereafter agrees in writing to such Trial Period and otherwise agrees to be bound by the provisions of this Agreement, the Stock Registration Agreement, the Stock Purchase Agreement and any J-V Agreement. If the ultimate parent of the acquiring entity accepts these conditions, the collaboration shall continue, and the Option shall expire unless the Electing Company exercises the Option within*** days prior to the expiration of the Trial Period. If the ultimate parent of the acquiring entity fails to give notice within the required period that it will be bound by the provisions of such aforementioned Agreements, the Electing Company shall be deemed to have exercised the Option as of the expiration of such *** day period and the Parties shall then follow the procedures set forth in this Section 10.3. 10.4. Substantial Stock Accumulation. (a) In the event of a Substantial Stock Accumulation, as that term is defined in Section 10.5(b), of either the P&G Parent or the Regeneron Parent (the "Affected Company"), at any time after the Substantial Stock Accumulation, the Party affiliated with the Affected Company may, but is not obligated to, inform the other Party in writing that the Party affiliated with the Affected Company regards such Substantial Stock Accumulation as being not in the best interests of the collaboration. This notice shall be separate from and in addition to the notice required under Sections 10.3 and 10.4(b). Upon receipt of any such notification stating that the Substantial Stock Accumulation is not in the best interests of the collaboration, the other Party or its Affiliates (the "Purchasing Company") shall have the option, at its election and upon notice to *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. the Affected Company within *** days after receipt of the Affected Company's notification of a Substantial Stock Accumulation, to purchase the Acquired Company Interest at the License Fee. (b) In the event of a Substantial Stock Accumulation in either the P&G Parent or the Regeneron Parent, as soon as the Party affiliated with the Affected Company has knowledge of the Substantial Stock Accumulation, it shall give prompt notice to the other Party. Such notice shall be separate from and in addition to the notice provided for in Sections 10.3 and 10.4(a) and must be given regardless of whether the Party affiliated with the Affected Company regards the Substantial Stock Accumulation as being not in the best interest of the collaboration. From the date on which the Party affiliated with the Affected Company has notice of the Substantial Stock Accumulation, the following provisions shall become effective and remain effective until the Substantial Stock Accumulation is eliminated, unless otherwise agreed: (i) If the Party that is not affiliated with the Affected Company reasonably determines in good faith that the person or entity making the Substantial Stock Accumulation is a competitor of such Party or its Affiliates, such Party may so inform the other Party in writing. Promptly after receipt of such notice, the Party affiliated with the Affected Company shall establish a procedure whereby no director or executive employee of the Affected Company who was not a director or employee of the Affected Company prior to the Substantial Stock Accumulation, and who was previously a director or employee of the person or entity making the Substantial Stock Accumulation (a "Tainted Director or Executive"), shall receive any of the following: (x) confidential information of the other Party and its Affiliates; and (y) confidential information of the collaboration, except that any such Tainted Director or Executive can be given information as to actual and projected sales and profits of the collaboration. (ii) If the Party that is not affiliated with the Affected Company does not give notice pursuant to this Section 10.4, the Party affiliated with the Affected Company shall establish a procedure whereby no Tainted Director or Executive shall receive confidential information of the other Party and its Affiliates but need not place any restrictions on confidential or other information of the collaboration. (iii) In the event of a material violation of this Section 10.4, the non-breaching Party may, without resort to the dispute resolution procedure set forth in Articles II and XI, bring an immediate court action or enjoin such violation and to recover any damages that it may have incurred by reasons of such violation. *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. 10.5. Definitions. (a) For purposes of this Agreement, a "Change in Control" of a company shall be deemed to have occurred in the event of (i) a merger, consolidation, reorganization, recapitalization, the purchase of substantially all of the company's assets, or other transaction in which or as result of which the common stock of the company, or a successor entity having the same ownership as the company, shall cease (except temporarily) to be a publicly traded security; or (ii) the acquisition by any individual, firm, corporation, or entity (other than any profit sharing or other employee benefit plan of the company or any Affiliate, or any employee or group of employees or former officers an/or directors of the company or its Affiliates) of beneficial ownership, directly or indirectly, of securities of the company representing more than *** of the combined voting power of the company's then outstanding voting securities. Notwithstanding the foregoing, The Procter & Gamble Company directly or indirectly must have at least *** percent of the combined voting power of Procter & Gamble's outstanding voting securities, otherwise there shall be a Change of Control of Procter & Gamble. (b) A "Substantial Stock Accumulation" of a company shall be deemed to have occurred in the event of the accumulation by any individual, firm, corporation, or entity (other than any profit sharing or other employee benefit plan of the company or any Affiliate, or any employee or group of employees or former officers an/or directors of the company or its Affiliates) of beneficial ownership, directly or indirectly, of securities of the company representing more than *** of the combined voting power of the company's then outstanding voting securities. Notwithstanding the foregoing, Leonard Schleifer, M.D., Ph.D., the present President and Chief Executive Officer of Regeneron, may accumulate more than *** percent of Regeneron's or Regeneron's Parent's combined voting power of its outstanding securities and no Substantial Stock Accumulation for Regeneron shall be deemed to have occurred. For the purposes of this Section 10.5(b), Dr. Schleifer's ownership of securities of Regeneron or Regeneron's Parent shall be deemed to be his direct or indirect ownership of capital shares or options to purchase such capital shares of Regeneron or Regeneron's Parent and the direct or indirect ownership of such shares by members of his family living in his household to the extent that Dr. Schleifer retains voting control, the power to exercise such options, and the right to dispose of such shares, and shall not include any other shares over which he does not possess Beneficial Ownership, as defined in the Securities and Exchange Act of 1934, as amended. *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. 10.6. The "License Fee" for purposes of Sections 10.3 and 10.4 shall be determined as follows: (a) License Fee has two components: a Valuation (as defined herein) of the Parties' interest in the Agreement or J-V Agreement with respect to Compounds to which neither Party has opted out in total and a running royalty on Net Sales of any Compound for which neither Party has opted out, such rate and term being calculated as per Section 6.1 ("Running Royalty"). Each Party shall designate an investment banking firm of its choice, and each investment banking firm will be asked to prepare an appraisal as to the fair market value of the collaboration as a going concern that would be received in cash from a Third Party if a sale of the collaboration were made to a Third Party, taking into account any contractual obligation of either Party or its Affiliates to refrain from manufacturing or marketing a product competitive with the Products in the Territory for any period, the value of the information, Patents and Know-how, and other assets being licensed and the potential market for such Compounds in the Territory ("Fair Market Value"). The Fair Market Value shall not include Compounds in specific countries or in the entire Territory for which either Party is an Opting Out Party, as such royalty shall continue to be governed pursuant to Section 6.1, regardless of a Change of Control. *** The investment bankers will be asked to submit their Valuations within thirty (30) days after the Purchase Date. In the event of a Party's failure to obtain an investment banking firm's Valuation within thirty (30) days after the Purchase Date, the Valuation will be the Valuation determined by the investment banking firm appointed by the other Party. An example of the operation of the License Fee is set forth in Attachment 10.6(a). (b) If the difference between the lower Valuation and the higher Valuation is not more than *** of the higher Valuation, or if the Valuations are equal, the final Valuation shall be the average of the Valuations. If the difference between the *** Valuations is more than *** of the higher Valuation, the investment bankers will select a third investment banking firm from those known as major bracket investment banking firms, and that firm shall also prepare a Valuation. The third investment banking firm will not have access to the Valuations prepared by the other investment banking firms. The *** Valuations that are the closest in value then shall be averaged, and the resulting average shall be the final Valuation. (c) The purchase of the interest shall thereafter be consummated by payment of the Valuation and the obligation to pay the Running Royalty within *** days after receipt of all investment bankers' valuations or such later date upon which all necessary regulatory *** Certain material has been omitted from this section pursuant to a request for confidential treatment and has been filed separately with the S.E.C. approvals have been obtained and/or regulatory waiting periods have expired. Advances (if applicable) shall be first subtracted from or added to (as the case may be) the Valuation, then any excess Advance shall be immediately payable by the Owing Party. (d) Each Party shall bear the expense of obtaining the Valuation of the investment bankers selected by such Party, and if a third investment banker is selected, the expense of obtaining its Valuation shall be borne equally by the Parties. (e) Unless otherwise agreed in writing by the Parties, the License Fee for a license under Sections 10.3, 10.4 and 10.5 shall be calculated as of the date of the Electing Company's notice that it elects to exercise the Option under Sections 10.3 or 10.4 or the Purchasing Company's notice that it desires to license the interest of the Party affiliated with the Affected Company under Section 10.3 (such date shall be referred to as the "Purchase Date"). (f) During the pendency of the Option election and valuation process, the Parties shall continue to perform their customary activities under this Agreement or any J-V Agreement. Article XI - Miscellaneous 11.1. Force Majeure. Neither Party shall lose any rights hereunder or be liable to the other Party for damages or loss on account of failure of performance by the Defaulting Party if the failure is occasioned by government action, war, fire, explosion, flood, strike, lockout, embargo, act of God, or any other similar cause beyond the reasonable control of the Defaulting Party, provided that the Party claiming force majeure has exerted all reasonable efforts to avoid or remedy such force majeure and given prompt notice to the other Party. 11.2.
