Each Development Plan shall be developed in good faith with the overall objective of optimizing the commercial potential of such Product. Each Development Plan shall describe the proposed overall program of Development for the applicable Product in the Territory, including preclinical studies, toxicology, formulation, process development, clinical studies, regulatory plans and other elements of obtaining Regulatory Approval(s) in each applicable country, as well as timelines for key regulatory authority meetings, Drug Approval Applications and Regulatory Approvals. Each Development Plan shall include a summary of estimated Development expenses of the program expected to be incurred during the Development process through obtaining Regulatory Approval for each proposed indication and route of delivery on a country-by-country basis. In the event of any inconsistency between the Development Plan and this Agreement, the terms of this Agreement shall prevail.

     (b) Initial Development Plan. Within thirty (30) days after the Effective Date, CRXX shall provide PGx with a draft Development Plan for PGx’s review. The Parties shall use commercially reasonable efforts to reach agreement on the initial Development Plan within sixty (60) days after the Effective Date (the “Initial Development Plan”). In the event the Parties are unable, despite using commercially reasonable efforts, to agree upon the Initial Development Plan within sixty (60) days after the Effective Date, CRXX may terminate this Agreement upon thirty (30) days written notice to PGx. Such a termination shall be considered a termination at will by CRXX under Section 13.2 for purposes of this Agreement.

     4.4 Diligent Development. CRXX shall use Diligent Efforts to Develop Products in the Territory. Any failure by CRXX to comply with the obligations set forth in this Section 4.4 shall be deemed to be a material breach of this Agreement, but only with respect to such country(ies) and/or jurisdiction(s) in which such failure occurs, for which PGx may exercise its rights under Article 13 to terminate the license granted under Section 2.1 with respect to such

779758 v7/HN

18


country(ies) and/or jurisdiction(s); provided, however, that if CRXX fails to use Diligent Efforts to Develop Product(s) in the United States of America or any of the Major EU Countries, PGx may exercise its termination rights under Article 13 with respect to this Agreement in its entirety in addition to any other available remedies at law or in equity.

     4.5 Development Reports. Each Party shall maintain complete and accurate records (in the form of technical notebooks and/or electronic files where appropriate) of all work conducted by it under the Development Plan and all Information resulting from such work. Such records, including any electronic files where such Information may also be contained, shall fully and properly reflect all work done and results achieved in the performance of the Development Plan in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes.

     4.6 Standards of Conduct. Each Party shall perform, and shall ensure that its Affiliates, sublicensees, and Third Party contractors perform, the Development activities for which it is responsible under the Development Plan in good scientific manner and in material compliance with applicable laws, rules and regulations.

     4.7 Development Expenses. Except as set forth in Section 4.8, to the extent that CRXX and PGx agree in writing that PGx will perform Development activities after the Effective Date, CRXX shall be responsible for all costs and expenses incurred by or on behalf of PGx in connection with such Development activities. In particular, CRXX shall pay for such costs and expenses as follows: (a) PGx personnel time at a rate of $250,000 per FTE per day (until December 31, 2010 and thereafter subject to the adjustment mechanism set forth below); and (b) any out-of-pocket expenses incurred by PGx will be reimbursed in full. Unless the Parties agree otherwise, such payments shall be made on a quarterly basis, based on written invoices submitted by PGx, and shall be due thirty (30) days after CRXX’s receipt of the applicable invoice. PGx shall provide, upon CRXX’s request, invoices, agreements and other reasonable documentation to support and document PGx’s out-of-pocket expenses.

4.8      Option to Co-Develop.
 
  (a) No later than ten (10) days after the first availability of a final study report
 

from the first Phase 2 Clinical Trial for the first Product to complete a Phase 2 trial, CRXX shall provide written notice to PGx of such event, which notice shall be accompanied by an updated Development Plan for such Product, an estimated budget for Development of such Product through Regulatory Approval in the United States, the European Union, and any other anticipated major markets, and reasonably detailed description of the Shared Development Costs incurred by CRXX prior to the date of such notice (the “Co-Development Notice”).

     (b) PGx shall have the option (the “Co-Development Option”) to co-fund fifty percent (50%) of the Shared Development Costs for Products, which option shall be exercisable by providing written notice to CRXX no later than ninety (90) days after PGx’s receipt of the Co-Development Notice. No later than thirty (30) days after PGx’s exercise of the Co-Development Option, PGx shall make a payment to CRXX equal to fifty percent (50%) of the Shared Development Costs incurred by CRXX prior to such exercise.

     (c) If PGx elects to exercise the Co-Development Option, the Parties shall share equally all Shared Development Costs, and the remaining terms of this Section 4.8(c) shall apply. Within forty-five (45) days after the end of each calendar quarter for as long as either Party is incurring Shared Development Costs, each Party shall submit to the JSC a statement setting forth the Shared Development Costs it incurred in such calendar quarter. Within thirty (30) days after receipt of such reports, the JSC shall notify the Parties whether a reconciliation payment is due from one Party to the other, and if so, the amount of such reconciliation payment, so that the Parties share equally the Shared Development Costs for such calendar quarter. The Party required to pay such reconciliation payment shall submit such payment to the other Party within thirty (30) days after receiving notice from the JSC.

     4.9 License Development Reports. If the Co-Development Option has expired and PGx has not exercised such option, on or before January 31 of each calendar year during the Term thereafter, CRXX shall provide the PGx with a written report that summarizes, in reasonable detail, all Development activities performed by CRXX and its Affiliates, sublicensees, and Third Party contractors during the preceding calendar year (each a, “License Development Report”), including safety data generated during such report period.

     (b) shall undertake a sales effort commensurate with optimizing the Commercialization of each Product taking into account the resources of CRXX and/or any sublicensee or partner.

Any failure by CRXX to comply with the obligations set forth in this Section 6.3 shall be deemed to be a material breach of this Agreement, but only with respect to such country(ies) and/or jurisdiction(s) in which such failure occurs, for which PGx may exercise its rights under Article 13 to terminate the license granted under Section 2.1 with respect to such country(ies) and/or jurisdiction(s); provided, however, that if CRXX fails to use Diligent Efforts to Commercialize Product(s) in the United States of America or any of the Major EU Countries, PGx may exercise its termination rights under Article 13 with respect to this Agreement in its entirety or any other available remedies at law or in equity.

Each milestone in this Section 8.2 shall be paid only once for the first Product to achieve such milestone. The maximum total amount of payment to PGx pursuant to this Section 8.2 shall be $100 million. CRXX shall notify and pay to PGx the amounts set forth in this Section 8.2 within thirty (30) days after the achievement of the applicable milestone event.

Each such payment is nonrefundable and noncreditable against any other payments due hereunder.

     8.3 Commercialization Milestone Payments. Provided that PGx has not exercised the Co-Development Option, CRXX shall make each of the milestone payments indicated below to PGx when annual aggregate Net Sales of all Products across all indications in the Territory first reach the specified dollar values in any calendar year.

Aggregate Net Sales in a Calendar Year    Payment 


                                     $100    million       $5 million 



                                     $250    million    $12.5 million 



                                     $500    million     $25    million 




                                         $1 billion     $50    million 



                                         $2 billion     $60    million 

Each milestone in this Section 8.3 shall be paid only once. The maximum total amount of payment to PGx pursuant to this Section 8.3 shall be $152.5 million. CRXX shall notify and pay to PGx the amounts set forth in this Section 8.3 within thirty (30) days after the achievement of the applicable milestone event.

     8.4 Royalties. For the term specified in Section 8.4(d), and provided that PGx has not exercised the Co-Development Option, CRXX shall pay to PGx royalties on Net Sales either as provided in Section 8.4(a), 8.4(b), or 8.4(c), as the case may be.

     (a) So long as the event described in Section 8.4(b) has not occurred, CRXX shall pay to PGx royalties on Net Sales, at an incremental royalty rate determined by annual Net Sales of all Products in aggregate in each calendar year as follows (subject to adjustment as set forth in Section 8.5):

Annual Net Sales of Products

Royalty Rate

779758 v7/HN

26


Portion less than or equal to $250 million    7% 


Portion greater than $250 million and less than or    8% 
equal to    $500 million     



Portion greater than $500 million and less than or    9% 
equal to    $1 billion     



Portion greater than $1 billion    10% 

For example, if the calendar year Net Sales to which the royalty obligations in this Section 8.4(a) apply were $400,000,000, the 7% royalty rate would apply to the first $250,000,000 of such Net Sales and the 8% royalty rate would apply to the final $150,000,000 of such Net Sales.

     (b) If (i) CRXX has entered into a sublicensing arrangement under which it granted a third party the right to market and sell the Product in one or more countries and/or jurisdictions and (ii) the lowest royalty rate that CRXX receives under such sublicensing arrangement is less than 15% of Net Sales, then following such event CRXX shall pay to PGx royalties on Net Sales at an alternative royalty rate determined by annual Net Sales of all Products in aggregate in each calendar year thereafter as follows (subject to adjustment as set forth in Section 8.5):

    Annual Net Sales of Products    Royalty Rate 



Portion less than or equal to $250 million    6% 


Portion greater than $250 million and less than or    7% 
equal to    $500 million     



Portion greater than $500 million and less than or    9% 
equal to    $1 billion     



Portion greater than $1 billion    10% 

Notwithstanding the foregoing, if the lowest royalty rate on Net Sales received by CRXX under such sublicensing arrangement is 15% of Net Sales or greater, then the applicable royalty rate(s) set forth in Section 8.4(a) (and not those in this Section 8.4(b)) shall apply to such portion of Net Sales. If in a particular calendar quarter there are Net Sales of a particular Product in one or more countries and/or jurisdictions by a Third Party pursuant to a sublicensing arrangement with CRXX to market and sell such Product in such country(ies) and/or jurisdiction(s) in which the lowest royalty rate on Net Sales is less than 15% (a “Section 8.4(b) Sublicensing

779758 v7/HN

27


Arrangement”) and there are also Net Sales of such Product in one or more countries and/or jurisdictions directly by CRXX or its Affiliates or pursuant to a sublicensing arrangement with CRXX to market and sell such Product in such country(ies) and/or jurisdiction(s) in which the lowest royalty rate on Net Sales is greater than or equal to 15% (a “Section 8.4(a) Sublicensing Arrangement”), then the royalties shall be calculated by determining the percentage of Net Sales in the Territory in such calendar quarter that are pursuant to a Section 8.4(b) Sublicensing Arrangement versus by CRXX and its Affiliates or pursuant to a Section 8.4(a) Sublicensing Arrangement and applying that percentage to each royalty tier to determine which portion of such amount should bear royalties at rates set forth in Section 8.4(a) as opposed to the rates set forth in this Section 8.4(b).

By way of example, if the aggregate Net Sales of a Product in a particular calendar quarter is $400 million, and comprised of $100 million of sales from a Section 8.4(b) Sublicensing Arrangement and $300 million of sales from CRXX and its Affiliates or pursuant to a Section 8.4(a) Sublicensing Arrangement, then the applicable percentage of Net Sales that are subject to the royalty rate in Section 8.4(b) shall be $100 million divided by $400 million, or one-fourth (1/4), and the applicable percentage of Net Sales that are subject to the royalty rate in Section 8.4(a) shall be $300 million divided by $400 million, or three-fourths (3/4). Applying such percentages, the amount of royalties payable (by way of example) under Section 8.4(a) and this Section 8.4(b) shall be as follows:

                             3/4      $250    million      7%     =      13.125    million 
                             1/4      $250    million x    6%         3.75 million 
                             3/4      $150    million      8%     =       9.0 million 
                             1/4      $150    million x    7%         2.625    million 









Total royalties $ 28.5 million                         

     (c) Know-How Royalty. In any country where there is no Collaboration Patent covering a particular Product or the manufacture or use of such Product at the time of sale, in consideration of licensed Know-How, CRXX shall owe royalties under Section 8.4(a) or 8.4(b) (as applicable) on the Net Sales of such Product in such country at rates that are seventy-five percent (75%) of the rates otherwise payable under Section 8.4(a) or 8.4(b) (as applicable). If in a particular calendar quarter there are Net Sales of a particular Product in one or more countries in which there is at least one Collaboration Patent covering such Product or its manufacture or use and there are also Net Sales of such Product in one or more countries in which there is no Collaboration Patent covering such Product or its manufacture or use, then the royalties shall be calculated by determining the percentage of Net Sales in the Territory in such calendar quarter that are in patented versus non-patented countries and applying that percentage to each royalty tier to determine which portion of such amount should bear royalties at rates set forth in Section 8.4(a) or 8.4(b) (as applicable) as opposed to the rates set forth in this Section 8.4(c).

By way of example, if the aggregate Net Sales of a Product in a particular calendar year is $400 million, and comprised of $100 million of sales from countries in which there is no Collaboration Patent covering the Product or its manufacture or use and $300 million of sales from countries in which there is at least one Collaboration Patent covering the Product or its manufacture or use,

779758 v7/HN

28


then the applicable percentage of Net Sales that are in non-patented countries shall be $100 million divided by $400 million, or one-fourth (1/4), and the applicable percentage of Net Sales that are in patented countries shall be $300 million divided by $400 million, or three-fourths (3/4). Applying such percentages, the amount of royalties payable (by way of example) under Section 8.4(a) and this Section 8.4(c) shall be as follows:

3/4      $250    million      7%        13.125    million 
1/4      $250    million x    5.25% =      3.281    million 
3/4      $150    million      8%         9.0 million 
1/4      $150    million x    6% =       2.25 million 







Total royalties                $    27.656    million 

     (d) Royalty Term. Royalties due under this Section 8.4 with respect to a particular Product in a particular country, will commence upon the First Commercial Sale of such Product in such country and will be payable until the later of (i) the expiration of the last to expire Collaboration Patent in such country that claims the Product, or its manufacture or use, and (ii) ten (10) years after the First Commercial Sale of such Product in such country (such period, the “Royalty Term”).

     (e) Royalty Payments and Reports. All amounts payable to PGx pursuant to this Section 8.4 shall be paid in United States dollars within thirty (30) days after the end of each calendar quarter with respect to Net Sales in such calendar quarter. Each payment of royalties due to PGx shall be accompanied by a statement, on a country-by-country basis, of the amount of gross sales of Product during the applicable calendar quarter, an itemized calculation of Net Sales showing deductions provided for in the definition of Net Sales during such calendar quarter, and a calculation of the amount of royalty payment due on such sales for such calendar quarter.

8.5      Reduction for Payments for Necessary Licenses.
 
  (a) If a Patent or Patents of a Third Party should exist in any country that
 

covers the composition of matter or manufacture of the Compound or the use of the Compound in the Field, and it is necessary or advisable for CRXX to obtain license(s) under such Patent or Patents to engage in the activity or activities licensed under this Agreement in particular country(-ies) (a “Necessary License”), then CRXX shall be entitled to a credit against the royalty payments due to PGx pursuant to Section 8.4 upon sales of Product in such country in an amount up to fifty percent (50%) of any royalties actually paid under such Necessary License with respect to such Product sales, provided that any credit against royalties due on sales of Products in a particular country shall not reduce such royalties by more than two percent (2%) of the Net Sales in such country. If in a particular calendar quarter there are Net Sales of a particular Product in one or more countries and/or jurisdictions for which royalties on Net Sales under a Necessary License are due and there are also Net Sales of such Product in one or more countries and/or jurisdictions for which no royalties are due under a Necessary License, then the royalties shall be calculated by determining the percentage of Net Sales in the Territory in such calendar quarter that are subject to a royalty under a Necessary License versus by those Net Sales that are not and applying that percentage to each royalty tier to determine which portion of such amount should

779758 v7/HN

29


bear royalties at rates set forth in Section 8.4(a) or 8.4(b), as applicable, as opposed to the rates set forth in this Section 8.5(a).

By way of example, if the aggregate Net Sales of a Product in a particular calendar quarter is $400 million, and comprised of $100 million of sales that are subject to a 3% royalty on Net Sales pursuant to a Necessary License (and therefore a 1.5% reduction to PGx) and $300 million of sales that are subject to royalties pursuant to Section 8.4(a), then the applicable percentage of Net Sales that are subject to the royalty rate in Section 8.5(a) shall be $100 million divided by $400 million, or one-fourth (1/4), and the applicable percentage of Net Sales that are subject to the royalty rate in Section 8.4(a) shall be $300 million divided by $400 million, or three-fourths (3/4). Applying such percentages, the amount of royalties payable (by way of example) under Section 8.4(a) and this Section 8.5(a) shall be as follows:

3/4      $250    million      7%        13.125 million 
1/4      $250    million x    5.5%         3.4375    million 
3/4      $150    million      8%         9.0 million 
1/4      $150    million x    6.5%         2.4375    million 









    Total royalties $ 28.0 million             

     (b) If PGx exercises the Co-Development Option, all payments under Third Party licenses (including, but not limited to, any payments under the UVA Agreement) that are paid by either Party with respect to a Product in the Territory prior to the First Commercial Sale of such Product shall be deemed Shared Development Costs and shared between CRXX and PGx in accordance with Section 4.8(c). If PGx exercises the Co-Development Option, all payments under Third Party licenses (including, but not limited to, any payments under the UVA Agreement) that are paid by either Party with respect to a Product in the Territory after the First Commercial Sale of such Product shall be deemed Allowable Expenses and included in the calculation of Product Profit for such Product pursuant to Section 8.6.

8.6      Profit-Share.
 
  (a) Share of Product Profit. Following PGx’s exercise of its Co-
 

Development Option, CRXX and PGx shall share equally in Product Profit arising from the sale of Product in the Field in the Territory. This share of Product Profit shall be in lieu of any payments set forth in Sections 8.1, 8.2, 8.3, and 8.4.

     (b) Payment. Within thirty (30) days after the end of each calendar quarter following the first Allowable Expenses to be incurred by a Party or the first Net Sales to be achieved by a Party, each Party shall report to the JSC its Net Sales and Allowable Expenses. Within thirty (30) days after receipt of such reports, the JSC shall provide a consolidated financial statement setting forth the Product Profit, calculating each Party’s fifty percent (50%) share of such Product Profit, and directing the remittance between the Parties of any payments due from one Party to the other Party in order to achieve such split of Product Profit. Any payment required by this Section 8.6(b) shall be made within thirty (30) days after so directed by the JSC.

779758 v7/HN

8.7      Taxes.
 
  (a) Cooperation and Coordination. The Parties acknowledge and agree that
 

it is their mutual objective and intent to minimize, to the extent reasonable, taxes payable with respect to their collaborative efforts under this Agreement and that they shall use their best efforts to cooperate and coordinate with each other to achieve such objective.

     (b) Payment of Tax. Subject to this Section 8.7(b), a Party receiving a payment pursuant to this Article 8 shall pay any and all taxes levied on such payment. If applicable law requires that taxes be withheld from a payment made pursuant to this Agreement (other than Section 8.6), the remitting Party shall (i) deduct the applicable withholding taxes from such amount; (ii) pay such withholding taxes to the proper taxing authority; and (iii) send evidence of the obligation together with proof of payment to the other Party within sixty (60) days following that payment. If applicable law requires that taxes be withheld from any payment made pursuant to Section 8.6, the remitting Party shall (1) pay the taxes to the proper taxing authority; and (2) send evidence of the obligation together with proof of payment to the other Party within sixty (60) days following that payment, and such payment shall be included in Allowable Expenses when calculating the remittance under Section 8.6(b).

     8.8 Blocked Currency. In each country where the local currency is blocked and cannot be removed from the country, royalties accrued on Net Sales in that country shall be paid to PGx in the equivalent amount in United States dollars.

     8.9 Foreign Exchange. The rate of exchange to be used in computing the amount of currency equivalent in United States dollars of Net Sales invoiced and Development Costs, Pre-Launch Commercialization Costs, and Allowable Expenses incurred in other currencies shall be made at the period-end rate of exchange quoted on the last business day of the applicable calendar quarter by Citibank in New York City or, to the extent mutually agreed by the Parties, any other widely accepted source of published exchange rates.

     8.10 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at the prime rate (as stated in the Wall Street Journal on the date such payment was due) plus four percent (4%) or the maximum rate allowable by applicable law, whichever is less.

     8.11 Financial Records; Audits. Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party to confirm the accuracy of the Shared Development Costs, Net Sales, and Allowable Expenses incurred or generated (as applicable) by such Party and the calculation of Product Profit, achievement of Commercialization milestones, royalty payments and other compensation payable under this Agreement. Upon reasonable prior notice of at least fifteen (15) business days, such records shall be open during regular business hours for a period of three (3) years from the creation of individual records for examination at the auditing Party’s expense, and not more often than once each calendar year, by an independent certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party for the sole purpose of verifying for the auditing Party the accuracy of the financial

779758 v7/HN

31


reports or Commercialization milestone notices furnished by the audited Party pursuant to this Agreement or of any payments made by the audited Party to the other pursuant to this Agreement. Any such auditor shall not disclose the audited Party’s Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments due by the audited Party under this Agreement. Any amounts shown to be owed but unpaid or overpaid and in need of reimbursement shall be paid or refunded (as the case may be) within thirty (30) days after the accountant’s report, plus interest (as set forth in Section 8.10) from the original due date. The auditing Party shall bear the full cost of such audit unless such audit discloses that the audited Party either paid too little or received too much payment because of a discrepancy in a report that the audited Party provided to the JSC during the applicable audit period, which underpayment or overpayment was equal to more than five percent (5%) of the amount set forth in such report, in which case the audited Party shall bear the full cost of such audit.

ARTICLE 9

INTELLECTUAL PROPERTY

     9.1 Ownership of Inventions. Each Party shall own all inventions and Information made solely by it and its Affiliates and their respective employees, agents, consultants and independent contractors in the course of conducting such Party’s activities under this Agreement (collectively, “Sole Inventions”). All inventions and Information that are made jointly by employees, Affiliates, agents, consultants or independent contractors of both Parties in the course of performing activities under this Agreement (collectively, “Joint Inventions”) shall be owned jointly by the Parties in accordance with joint ownership interests of co-inventors under United States patent laws.

     9.2 Disclosure of Inventions. Each Party shall promptly disclose to the other all Sole Inventions or Joint Inventions, including all invention disclosures or other similar documents submitted to such Party by its, or its Affiliates’, employees, agents or independent contractors describing such Sole Inventions or Joint Inventions. Such Party shall also respond promptly to reasonable requests from the other Party for more Information relating to such inventions.

9.3      Prosecution of Patents.
 
  (a) PGx Patents Other Than Joint Patents. Except as otherwise provided in
 

this Section 9.3(a), as between the Parties, PGx shall have the sole right and authority to prepare, file, prosecute (including any interferences, reissue proceedings and reexaminations) and maintain the PGx Patents in any jurisdiction in the Territory. For the avoidance of doubt, Joint Patents shall be prepared, filed, prosecuted and maintained pursuant to Section 9.3(c). PGx shall provide CRXX reasonable opportunity to review and comment on such prosecution efforts regarding such PGx Patents in the Territory. PGx shall provide CRXX with a copy of material communications from any patent authority in the Territory regarding such PGx Patents, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. If PGx determines in its sole discretion to abandon or not maintain any PGx Patent anywhere in the Territory, then

779758 v7/HN

32


PGx shall provide CRXX written notice of such determination at least thirty (30) days before any deadline for taking action to avoid abandonment and, to the extent permitted under the UVA Agreement, shall provide CRXX with the opportunity to prepare, file, prosecute and maintain such PGx Patent in the Territory on behalf of PGx. If CRXX desires PGx to file, in a particular jurisdiction in the Territory, a PGx Patent that claims priority to another PGx Patent, CRXX shall provide written notice to PGx requesting that PGx file such patent application in such jurisdiction. If CRXX provides such written notice to PGx, PGx shall either (i) file and prosecute such patent application and maintain any patent issuing thereon in such jurisdiction, or (ii) notify CRXX that PGx does not desire to file such patent application and provide CRXX with the opportunity to file and prosecute such patent application and maintain any patent issuing thereon on behalf of PGx. CRXX’s rights under this Section 9.3 with respect to any PGx Patent licensed to PGx by a Third Party shall be subject to the rights of such Third Party to file, prosecute, and/or maintain such PGx Patent.

     (b) CRXX Patents Other Than Joint Patents. Except as otherwise provided in this Section 9.3(b), CRXX shall have the sole right and authority to prepare, file, prosecute (including any interferences, reissue proceedings and reexaminations) and maintain the CRXX Patents in any jurisdiction in the Territory. For the avoidance of doubt, Joint Patents shall be prepared, filed, prosecuted and maintained pursuant to Section 9.3(c). PGx’s rights under this Section 9.3 with respect to any CRXX Patent licensed to CRXX by a Third Party shall be subject to the rights of such Third Party to file, prosecute, and/or maintain such CRXX Patent. In addition:

     (i) CRXX shall provide PGx reasonable opportunity to review and comment on such prosecution efforts regarding such CRXX Patents.

     (ii) CRXX shall provide PGx with a copy of material communications from any patent authority in the Territory regarding such CRXX Patents, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses.

     (iii) If CRXX determines in its sole discretion to abandon or not maintain any CRXX Patent anywhere in the world, then CRXX shall provide PGx with written notice of such determination at least thirty (30) days before any deadline for taking action to avoid abandonment and shall provide PGx with the opportunity to prepare, file, prosecute and maintain such CRXX Patent in the applicable jurisdiction on behalf of CRXX.

     (iv) If PGx desires CRXX to file, in a particular jurisdiction, a CRXX Patent that claims priority to another CRXX Patent, PGx shall provide written notice to CRXX requesting that CRXX file such patent application in such jurisdiction.

     (v) If PGx provides such written notice to CRXX, CRXX shall either (i) file and prosecute such patent application and maintain any patent issuing thereon in such jurisdiction, or (ii) notify PGx that CRXX does not desire to file such patent application and provide PGx with the opportunity to file and prosecute such patent application and maintain any patent issuing thereon on behalf of CRXX.

779758 v7/HN

33


Notwithstanding anything to the contrary herein, following expiration of the Co-Development Option without exercise by PGx, subsections (i) through (v) above shall only apply with respect to CRXX Patents that are relevant to the Retained Field.

     (c) Joint Patents. With respect to any potentially patentable Joint Invention, the Parties shall meet and agree upon which Party, if any, shall prepare, file, prosecute (including any interferences, reissue proceedings and reexaminations) and maintain patent applications covering such Joint Invention (any such patent application and any patents issuing therefrom a “Joint Patent”) in any jurisdictions throughout the Territory. It is the intention of the Parties that, unless otherwise agreed in writing, CRXX would prepare, file, prosecute and maintain any Joint Patents in the Territory. The Party that prosecutes a patent application in the Joint Patents (the “Prosecuting Party”) shall provide the other Party reasonable opportunity to review and comment on such prosecution efforts regarding the applicable Joint Patents in the particular jurisdictions, and such other Party shall provide the Prosecuting Party reasonable assistance in such efforts. The Prosecuting Party shall provide the other Party with a copy of all material communications from any patent authority in the applicable jurisdictions regarding the Joint Patent being prosecuted by such Party, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. In particular, each Party agrees to provide the other Party with all information necessary or desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any patent authority. Either Party may determine that it is no longer interested in supporting the continued prosecution or maintenance of a particular Joint Patent in a country or jurisdiction, in which case: (i) the disclaiming Party shall, if requested in writing by the other Party, assign its ownership interest in such Joint Patent in such country or jurisdiction to the other Party for no additional consideration, and (ii) if such assignment is effected, any such Joint Patent would thereafter be deemed a PGx Patent in the case of assignment to PGx, or a CRXX Patent in the case of assignment to CRXX.

     (d) Cooperation in Prosecution. Each Party shall provide the other Party all reasonable assistance and cooperation in the Patent prosecution efforts provided above in this Section 9.3, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution.

     (e) Patent Expenses. If PGx exercises the Co-Development Option, then prior to the First Commercial Sale of a Product in the Territory, any Patent Expenses incurred by a Party (whether incurred before or after such Co-Development Option Exercise) for the purpose of preparing, filing, prosecuting, or maintaining a Collaboration Patent in the Territory shall be deemed Shared Development Costs and borne equally by the Parties. If PGx exercises the Co-Development Option, then following the First Commercial Sale of a Product in the Territory, Patent Expenses incurred by a Party for the purpose of preparing, filing, prosecuting, or maintaining a Collaboration Patent in the Territory shall be deducted as an Allowable Expense from Net Sales when calculating Product Profit. In all other instances, CRXX shall be solely responsible for all Patent Expenses incurred by a Party for the purpose of preparing, filing, prosecuting or maintaining a Collaboration Patent in the Territory other than PGx Patents relating to the manufacture or use of the Compound for use in the in indications outside the Field, and

779758 v7/HN

34


CRXX shall reimburse PGx all Patent Expenses incurred by PGx pursuant to Section 9.3 within thirty (30) days after CRXX’s receipt of an invoice for such expenses from PGx.

9.4      Enforcement of Collaboration Patents.
 
  (a) Notification. If there is any infringement, threatened infringement, or
 

alleged infringement of the Collaboration Patents on account of a Third Party’s manufacture, use or sale of a Product in the Field (in each case, a “Product Infringement”), then each Party shall promptly notify the other Party in writing of any such Product Infringement of which it becomes aware, and shall provide evidence in such Party’s possession demonstrating such Product Infringement.

     (b) Enforcement Rights – No Co-Development. This Section 9.4(b) shall apply unless and until PGx exercises its Co-Development Option.

     (i) Subject to Section 9.4(e) and the remainder of this Section 9.4(b), CRXX shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity engaged in such Product Infringement of the Collaboration Patents in the Territory. If, CRXX has not brought suit to enforce such Collaboration Patent against such person or entity within one hundred twenty (120) days after CRXX’s receipt or delivery (as applicable) of notice and Information under Section 9.4(a), then PGx shall have the right to commence a suit or take action to enforce the applicable Collaboration Patents with respect to such Product Infringement in the Territory. Each Party shall provide to the Party enforcing any such rights under this Section 9.4(b) reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by applicable law to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts.

     (ii) The Party bringing a claim, suit or action under Section 9.4(b)(i) against any person or entity engaged in Product Infringement of the Collaboration Patents in the Territory shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages from such Third Party in such suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, and any remaining amount shall be distributed as follows: (1) if CRXX is the enforcing Party and the suit relates to a CRXX Patent(s), then any remaining amount shall be retained by CRXX, (2) if CRXX is the enforcing Party and the suit relates to a PGx Patent(s) and/or Joint Patent(s), then any remaining amount shall be allocated sixty percent (60%) to CRXX and forty percent (40%) to PGx to the extent the damages relate to PGx Patent(s) and sixty percent (60%) to CRXX and forty percent (40%) to PGx to the extent the damages relate to Joint Patent(s), (3) if PGx is the enforcing Party and the suit relates to a PGx Patent, then any remaining amount shall be retained by PGx and (4) if PGx is the enforcing Party and the suit relates to a CRXX Patent and/or Joint Patent, then any remaining amount shall be allocated sixty percent (60%) to PGx and forty percent (40%) to CRXX. CRXX acknowledges and agrees that UVAPF is entitled to receive a portion of any damages paid by an alleged infringer as a result of an infringement suit brought under a PGx Patent licensed by PGx under

779758 v7/HN

35


the UVA Agreement (after reimbursement of expenses), and that the allocation between PGx and CRXX described in this Section 9.4(b)(ii) shall be applied to the remainder of such damages after payment to UVAPF has been satisfied.

     (c) Enforcement Rights – Co-Development. This Section 9.4(c) shall apply if PGx exercises the Co-Development Option.

     (i) Promptly after either Party provides the other Party with a notice and Information in accordance with Section 9.4(a) with respect to Product Infringement of one or more Collaboration Patents, the Parties shall discuss whether they both wish to enforce such Collaboration Patents. If both Parties wish to enforce such Collaboration Patents, then PGx and CRXX shall jointly agree upon the logistics for such enforcement, and Section 9.4(c)(ii) shall apply. If only one Party wishes to enforce such Collaboration Patents, then, subject to Sections 9.4(c)(iii), 9.4(d), and 9.4(e), such Party shall have the right, but not the obligation, to bring an appropriate suit or other action against any person or entity engaged in such Product Infringement of the Collaboration Patents. Each Party shall provide to the Party enforcing any such rights under this Section 9.4(c)(i) reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by applicable law to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts.

     (ii) If the Parties agreed pursuant to Section 9.4(c)(i) that they both wished to enforce one or more Collaboration Patents against the alleged Product Infringement, then all expenses (including, for this purpose, a reasonable allocation of expenses of internal counsel) incurred by either Party as a result of bringing the resulting claim, suit or action under Section 9.4(c)(i) against the person or entity engaged in such Product Infringement shall be deemed Allowable Expenses. If either Party recovers monetary damages from such Third Party in such suit or action, such recovery shall be included in Net Sales. CRXX acknowledges and agrees that UVAPF is entitled to receive a portion of any damages paid by an alleged infringer as a result of an infringement suit brought under a PGx Patent licensed by PGx under the UVA Agreement (after reimbursement of expenses), and that the inclusion in Net Sales described in the preceding sentence shall only apply to the remainder of such damages.

     (iii) If only one Party wished to enforce one or more Collaboration Patents in the Territory, then the Party bringing the resulting claim, suit or action under Section 9.4(b)(i) against the person or entity engaged in such Product Infringement of the Collaboration Patents in the Territory shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages from such Third Party in such suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel), and any remaining amount shall be allocated between the Parties as follows: (1) if CRXX is the enforcing Party and the suit relates to a CRXX Patent(s), then any remaining amount shall be retained by CRXX, (2) if CRXX is the enforcing Party and the suit relates to a PGx Patent(s) and/or Joint Patent(s), then any remaining amount shall be allocated seventy percent (70%) to CRXX and thirty percent (30%) to PGx to the extent

779758 v7/HN

36


the damages relate to the PGx Patent(s) and seventy percent (70%) to CRXX and thirty percent (30%) to PGx to the extent the damages relate to the Joint Patent(s), (3) if PGx is the enforcing Party and the suit relates to a PGx Patent, then any remaining amount shall be retained by PGx and (4) if PGx is the enforcing Party and the suit relates to a CRXX Patent and/or Joint Patent, then any remaining amount shall be allocated seventy percent (70%) to PGx and thirty percent (30%) to CRXX. CRXX acknowledges and agrees that UVAPF is entitled to receive a portion of any damages paid by an alleged infringer as a result of an infringement suit brought under a PGx Patent licensed by PGx under the UVA Agreement (after reimbursement of expenses), and that the allocation between PGx and CRXX described in this Section 9.4(c)(iii) shall be applied to the remainder of such damages.

     (d) Settlement. Without the prior written consent of the other Party, neither Party shall settle any claim, suit or action that it brought under this Section 9.4 involving Collaboration Patents in any manner that would negatively impact such intellectual property or that would limit or restrict the ability of either Party or their Affiliates or licensees to sell Products anywhere in the Territory.

INDEMNIFICATION

11.1 Indemnification by PGx. PGx shall defend, indemnify, and hold CRXX, its

Affiliates, and their respective officers, directors, employees, and agents (the “CRXX

779758 v7/HN

39


Indemnitees”) harmless from and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such CRXX Indemnitees, all to the extent resulting from claims, suits, proceedings or causes of action brought by such Third Party (“CRXX Claims”) against such CRXX Indemnitee based on or arising out of: (a) a breach of any of PGx’s representations, warranties, and obligations under the Agreement; or (b) the negligence or willful misconduct of PGx, its Affiliates, or their respective officers, directors, employees, or agents. The foregoing indemnity obligation shall not apply if the CRXX Indemnitees materially fail to comply with the indemnification procedures set forth in Section 11.3, or to the extent that such CRXX Claim is based on or arises out of: (i) a breach of any of CRXX’s representations, warranties, and obligations under the Agreement; or (ii) the negligence or willful misconduct of CRXX, its Affiliates, or their respective officers, directors, employees, or agents.

     11.2 Indemnification by CRXX. CRXX shall defend, indemnify, and hold PGx, its Affiliates, and their respective officers, directors, employees, and agents (the “PGx Indemnitees”) harmless from and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such PGx Indemnitees, all to the extent resulting from claims, suits, proceedings or causes of action brought by such Third Party (“PGx Claims”) against such PGx Indemnitee based on or arising out of: (a) the Development, manufacture, storage, handling, use, promotion, Commercialization, sale, offer for sale, and importation of Products by CRXX or its Affiliates, sublicensees, or distributor (but excluding any such activities that occur after PGx’s exercise of the Co-Development Option); (b) a breach of any of CRXX’s representations, warranties, and obligations under the Agreement; or (c) the negligence or willful misconduct of CRXX, its Affiliates, or their respective officers, directors, employees, or agents.

11.3 Indemnification Procedures. The Party claiming indemnity under this Article

11 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of the claim, suit, proceeding or cause of action for which indemnity is being sought (“Claim”). The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. So long as the Indemnifying Party is actively defending the Claim, the Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the

779758 v7/HN

40


Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article 11.

     11.4 Third Party Claims Related to Products. Damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by either Party (collectively, “Damages”) from Third Party claims relating to the manufacture, use, handling, storage, sale or other disposition of any Product (including without limitation Damages from claims of infringement of Third Party patent rights) following PGx’s exercise of the Co-Development Option, shall be included within the Shared Development Costs or Allowable Expenses of the affected Party, as applicable, except that Damages will not be so included (and will be handled as set forth in Section 11.1 or 11.2, as applicable), to the extent they result from: (a) the other Party’s breach of any of its representations, warranties or obligations under this Agreement; or (b) the negligence or willful misconduct of the other Party, its Affiliates, or their respective employees, agents or independent contractors. If either Party receives notice of a Third Party claim that may be subject to this Section 11.4, such Party shall inform the other Party in writing as soon as reasonably practicable, and the Parties shall discuss a strategy on how to defend against such Third Party claim.

     11.5 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 11.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 11.1, 11.2 OR 11.4, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ARTICLE 12.

     11.6 Insurance. Each Party shall procure and maintain insurance, including product liability insurance, adequate to cover its obligations hereunder and which are consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being clinically tested in human subjects or commercially distributed or sold. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 11. Each Party shall provide the other with written evidence of such insurance upon request. For clarity, CRXX’s obligations under this Section 11.6 are in addition to CRXX’s obligations under Article 12 of the UVA Agreement (i.e., pursuant to Section 2.7(e)(ii) of this Agreement).

ARTICLE 12

CONFIDENTIALITY

     12.1 Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, each Party agrees that, for the Term and for seven (7)

779758 v7/HN

41


years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement any Confidential Information of the other Party except for that portion of such information or materials that the receiving Party can demonstrate by competent documentary proof:

     (a) was already known to the receiving Party or its Affiliate, other than under an obligation of confidentiality, at the time of disclosure by the other Party;

     (b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

     (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement;

     (d) is subsequently disclosed to the receiving Party or its Affiliate by a Third Party without obligations of confidentiality with respect thereto; or

     (e) is subsequently independently discovered or developed by the receiving Party or its Affiliate without the aid, application, or use of Confidential Information.

     For clarity, any Information generated during or resulting from the Collaboration that is generated by a Party may be used by such Party for any purpose that does not violate Section 2.10 or applicable laws or regulations, but disclosure of such Confidential Information shall be governed by this Article 12.

     12.2 Authorized Disclosure. Each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following situations:

     (a) regulatory filings and other filings with Governmental Authorities, including filings with the SEC, with respect to a Product;

(b)      prosecuting or defending litigation relating to this Agreement;
 
(c)      complying with applicable laws and regulations, including regulations
 

promulgated by securities exchanges;

     (d) disclosure to its Affiliates, employees, agents, and independent contractors, and any sublicensees of Collaboration Technology only on a need-to-know basis and solely as necessary in connection with the performance of this Agreement, provided that each disclosee must be bound by similar obligations of confidentiality and non-use at least as equivalent in scope as those set forth in this Article 12 prior to any such disclosure; and

     (e) solely with respect to the material terms of this Agreement, disclosure to any bona fide potential or actual investor, investment banker, acquirer, merger partner, or other potential or actual financial partner; provided that in connection with such disclosure, the

779758 v7/HN

42


disclosing Party shall use all reasonable efforts to inform each disclosee of the confidential nature of such Confidential Information and cause each disclosee to treat such Confidential Information as confidential.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to this Section 12.2, it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use reasonable efforts to limit the scope of such disclosure, as well as any subsequent use or disclosure of the information so disclosed, by seeking confidential treatment, a protective order, or the like. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder. All documents and other materials which embody the Confidential Information of a Party will be returned to such Party promptly following termination of this Agreement, and no copies, extracts or other reproductions shall be retained by the other Party, except that one copy may be retained by the other Party’s legal counsel to ascertain compliance with this Agreement; provided that a Party shall not be required to return Information generated under the Collaboration.

12.3      Publicity; Terms of Agreement.
 
  (a) The Parties agree that the material terms of this Agreement are the
 

Confidential Information of both Parties, subject to the special authorized disclosure provisions set forth in Section 12.2 and this Section 12.3.

     (b) If either Party desires to make a public announcement concerning the material terms of this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (except as otherwise provided herein), such approval not to be unreasonably withheld. A Party commenting on such a proposed press release shall provide its comments, if any, within two (2) business days after receiving the press release for review. PGx shall have the right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved and the achievements of Regulatory Approvals as they occur, subject only to the review procedure set forth in the preceding sentence. In relation to CRXX’s review of such an announcement, CRXX may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the information that the relevant milestone has been achieved and triggered a payment hereunder. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that have already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 12.3.

     (c) The Parties acknowledge that PGx or CRXX may be obligated to file a copy of this Agreement with the SEC. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of at least the commercial terms and sensitive technical terms hereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, the filing Party will provide the other Party with a copy of the Agreement a reasonable time in advance of filing marked to show provisions for which the filing Party intends to seek confidential treatment and shall reasonably consider and

779758 v7/HN

43


incorporate the other Party’s comments thereon (which shall be provided to the filing Party a reasonable time in advance of filing) to the extent consistent with the legal requirements governing redaction of information from material agreements that must be publicly filed.

     12.4 Publications. Neither Party shall publicly present or publish results of studies carried out under this Agreement (each such presentation or publication, a “Publication”) without the opportunity for prior review by the other Party. The submitting Party shall provide the other Party the opportunity to review any proposed Publication at least thirty (30) days prior to the earlier of its presentation or intended submission for publication. The submitting Party agrees, upon request by the other Party, not to submit or present any Publication until the other Party has had an additional thirty (30) days to comment on any material in such Publication and to make patent filings. The submitting Party shall consider the comments of the other Party in good faith, but will retain the sole authority to submit the manuscript (other form of publication) for Publication. The submitting Party shall provide the other Party a copy of the Publication at the time of the submission or presentation. Notwithstanding the foregoing, CRXX shall not have the right to publish or present PGx’s Confidential Information without PGx’s prior written consent, and PGx shall not have the right to publish or present CRXX’s Confidential Information without CRXX’s prior written consent; provided, however, that for purpose of this sentence Information generated by the Collaboration that is considered Confidential Information of both Parties shall not be subject to the restriction of this sentence. In addition, CRXX may publish and present research (pre-clinical and clinical) conducted by or on behalf of it or its partners or licensees on A2a Agonists that is not conducted as part of the Collaboration. If the Co-Development Option expires without exercise by PGx, PGx shall have no right to publish or present any Publication with respect to results of studies completed after the expiration of the Co-Development Option. The Parties further acknowledge that PGx (and its predecessor in interest, ATL) has made significant contributions to the discovery of the Compound as of the Effective Date and the Parties agree that any public disclosure made after the Effective Date regarding Compounds and/or Products shall give appropriate recognition to the PGx scientists who are responsible for the discovery of such Compounds and/or Products.

ARTICLE 13

TERM AND TERMINATION

     13.1 Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 13, shall remain in effect until the cessation of all commercial sales of Products in the Territory (the “Term”).

     13.2 Termination by CRXX at Will. CRXX shall have the right to terminate this Agreement in its entirety upon one hundred twenty (120) days prior written notice to PGx. Upon termination pursuant to this Section 13.2, and in addition to the consequences described in Section 13.5 and the remedies provided in Section 13.6, CRXX shall remain responsible for its share of all committed Shared Development Costs contemplated by the Development Plan in effect as of the date of such notice of termination and shall receive its Product Profit for all periods prior to the termination date; and CRXX shall not, during the applicable notice period, take any action that would adversely affect or impair the further Development or

779758 v7/HN

44


Commercialization of the Products; provided, however, that CRXX may discontinue all or part of its Development or Commercialization activities if CRXX provides PGx written notice of such intended discontinuance of activities and PGx does not object in writing within thirty (30) days of such written notice, such objection to be reasonably based if the Co-Development Option has expired without exercise by PGx.

13.3      Termination by Either Party for Breach.
 
  (a) Breach. Subject to Section 13.3(b) and (c), PGx shall have the right to
 

terminate this Agreement upon written notice to CRXX if CRXX, after receiving written notice from PGx identifying a material breach by CRXX of its obligations under this Agreement, fails to cure such material breach within sixty (60) days from the date of such notice (or within twenty (20) business days notice in the event such material breach relates to CRXX’s failure to pay any amounts due PGx hereunder). For the avoidance of doubt, CRXX’s failure to pay the amount set forth in Section 8.1 shall be deemed to be a material breach of this Agreement. Subject to Section 13.3(c), CRXX shall have the right to terminate this Agreement upon written notice to PGx if PGx, after receiving written notice from CRXX identifying a material breach by PGx of its obligations under this Agreement, fails to cure such material breach within sixty (60) days from the date of such notice (or within twenty (20) business days notice in the event such material breach relates to PGx’s failure to pay any amounts due CRXX hereunder).

(b) Diligence Breach. PGx may terminate the license granted to CRXX

under Section 2.1 upon written notice to CRXX if CRXX, after receiving written notice from PGx identifying a material breach by CRXX of its obligations under Section 4.4 or 6.3, fails to cure such material breach within sixty (60) days from the date of such notice, with respect to such country(ies) and/or jurisdiction(s) in which such failure remains uncured after such sixty (60) day cure period; provided, however, that if CRXX fails to use Diligent Efforts to Develop or Commercialize Product(s) in the United States of America or any of the Major EU Countries, PGx may exercise its termination rights under Sections 13.3(a), 4.4 and 6.3 or any other available remedies at law or in equity.

     (c) Disputed Breach. If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a notice provided by the other Party in accordance with Section 13.3(a) or (b), and such alleged breaching Party provides the other Party notice of such dispute within such sixty (60) day period, then the non-breaching Party shall not have the right to terminate this Agreement or the license granted under Section 2.1 under Section 13.3(a) or (b), respectively, unless and until an arbitrator, in accordance with Article 14, has determined that the alleged breaching Party has materially breached the Agreement and that such Party fails to cure such breach within sixty (60) days following such arbitrator’s decision (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within twenty (20) business days following such arbitrator’s decision) plus interest from the original due date per Section 8.10. It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.

779758 v7/HN

     13.4 Termination for Patent Challenge. PGx may terminate this Agreement in its entirety if CRXX or its Affiliates or sublicensees, directly or indirectly, individually or in association with any other person or entity, challenge the validity, enforceability or scope of any PGx Patent anywhere in the Territory. CRXX may terminate this Agreement in its entirety if PGx or its Affiliates or sublicensees, directly or indirectly, individually or in association with any other person or entity, challenge the validity, enforceability or scope of any CRXX Patent anywhere in the Territory.

     13.5 Effect of Termination of the Agreement. Upon termination of this Agreement by CRXX under Section 13.2, by PGx under Section 13.3 or by either Party under 13.4, the following shall apply (in addition to any other rights and obligations under Section 13.2 and Section 13.6 or otherwise under this Agreement with respect to such termination):

     (a) Licenses. The licenses granted in Sections 2.1 and 2.2 shall terminate. Notwithstanding the foregoing, CRXX hereby grants to PGx, effective only upon such termination, (i) if PGx has exercised the Co-Development Option, an exclusive, worldwide, fully-paid, perpetual, irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses, under any method of use CRXX Patents and CRXX Know-How to the extent necessary to Develop, make, have made, use, import, export, sell, offer for sale and otherwise Commercialize Products in the Field and, (ii) an exclusive, worldwide, fully-paid, perpetual, irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses to any method of use CRXX Patents and CRXX Know-How that have been developed, conceived or reduced to practice as a result of activities undertaken pursuant to this Agreement to the extent applicable to the Retained Field, in the Retained Field, provided such CRXX Know-How remains subject to Article 12. In addition, regardless of whether PGx has exercised the Co-Development Option, CRXX shall assign to PGx any Third Party agreements referenced in Section 2.8.

    (b)    Marks. CRXX shall assign to PGx all right, title and interest in and to the 
Marks.         
 
    (c)    Regulatory Materials. CRXX shall transfer and assign to PGx all 

Regulatory Materials and Regulatory Approvals for Products in the Territory that are Controlled by CRXX or its Affiliates or sublicensees.

     (d) Transition Assistance. CRXX shall, at no cost to PGx, share with PGx all CRXX Know-How created or developed during the Collaboration, and, at PGx’s request, all then-existing commercial arrangements, in each case that is, or are, reasonably necessary or useful for PGx to commence or continue researching, Developing, manufacturing, or Commercializing Products, including without limitation transferring, upon request of PGx, any material agreements or arrangements with Third Party suppliers or vendors to supply or sell Product in the Territory. If any such contract between CRXX and a Third Party is not assignable to PGx or if CRXX manufactures the Product itself (and thus there is no contract to assign), then CRXX shall reasonably cooperate with PGx to arrange to continue to obtain such license and/or supply from such entity, and CRXX shall supply such bulk Compound or finished Product, as applicable, to PGx, at one hundred and ten percent (110%) of CRXX’s actual cost for procuring

779758 v7/HN

46


such Compound or finished Product for a reasonable period not to exceed one (1) year until PGx establishes an alternate, validated source of supply for the Products.

     (e) Remaining Inventories. At PGx’s request, CRXX shall transfer to PGx all of the inventory of Compounds and Products held by CRXX as of the date of termination (including, without limitation, raw materials, intermediates, and finished, unfinished, or partially finished goods). PGx shall notify CRXX within sixty (60) days after the date of termination whether PGx wishes to receive such inventory.

     (f) Confidential Information. All Information generated or resulting from the Collaboration, whether generated by one or both Parties, to the extent relating to the Compound and/or the Products in the Field (“Collaboration Information”), shall be deemed the Confidential Information of PGx commencing on the effective date of termination of this Agreement; provided, however, that no license to any CRXX Technology is granted hereby. Additionally, as of the effective date of such termination, all Information required to be provided to PGx pursuant to Section 3.8 that was deemed the Confidential Information of CRXX under Section 1.15 shall be deemed Confidential Information of PGx. PGx hereby grants to CRXX, effective only upon such termination, a non-exclusive, worldwide, fully-paid, perpetual, irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses, to use the Collaboration Information generated by CRXX and in the possession or control of CRXX at the time of termination, solely for any purpose other than with respect to (i) the Compound or a Product or (ii) the Retained Field, provided that such Collaboration Information remains subject to Article 12.

     13.6 Other Remedies. Termination or expiration of this Agreement for any reason shall not release either Party from any liability or obligation that already has accrued prior to such expiration or termination, nor affect the survival of any provision hereof to the extent it is expressly stated to survive such termination. Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration.

     13.7 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by PGx and CRXX are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code. The Parties agree that each Party, as licensee of certain rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the United States Bankruptcy Code. The Parties further agree that, in the event of the commencement a bankruptcy proceeding by or against a Party (such Party, the “Bankrupt Party”) under the United States Bankruptcy Code, the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property licensed to such other Party and all embodiments of such intellectual property, which, if not already in such other Party’s possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon such other Party’s written request therefor, unless the Bankrupt Party elects to continue to perform all of its obligations under this Agreement or (b) if not

779758 v7/HN

47


delivered under clause (a), following the rejection of this Agreement by the Bankrupt Party upon written request therefor by the other Party.

     13.8 Survival. The following provisions shall survive any expiration or termination of this Agreement for the period of time specified: Sections 8.11, 9.1, 9.2 (solely with respect to Inventions made prior to such expiration or termination), 10.3, 13.5, 13.6, 13.7, and 13.8, and Articles 11, 12, 14, and 15, and any relevant definitions in Article 1 or Exhibit A.

     14.1 Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 14 if and when a dispute arises under this Agreement.

     (a) Referred From Joint Steering Committee. With respect to disputes, controversies or differences arising from the JSC pursuant to Article 3, such matter shall be resolved in accordance with Section 3.5.

     (b) Arising Between the Parties. In the event of any disputes, controversies or differences which may arise between the Parties and not from the JSC, out of or in relation to or in connection with this Agreement, including, without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of either Party, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the Chief Executive Officers of each Party. If the matter is not resolved within thirty (30) days following the request for discussions, either Party may then invoke the provisions of Section 14.2.

     14.2 Arbitration. Any dispute, controversy or claim arising out of or relating to the validity, construction, interpretation, enforceability, breach, performance, application or termination of this Agreement that is not resolved pursuant to Section 14.1, except for a dispute, claim or controversy under Section 14.12, shall be settled by binding arbitration administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures of JAMS then in effect (the “JAMS Rules”), except as otherwise provided herein. The arbitration shall be governed by the United States Federal Arbitration Act, 9 U.S.C. §§ 1-16 (the “Federal Arbitration Act”), to the exclusion of any inconsistent state laws. The United States Federal Rules of Civil Procedure shall govern discovery and the rules of evidence for the arbitration. The arbitration will be conducted in Boston, Massachusetts and the Parties consent to the personal jurisdiction of the United States federal courts, for any case arising out of or otherwise related to this arbitration, its conduct and its enforcement. Any situation not expressly covered by this Agreement shall be decided in accordance with the JAMS Rules.

     14.3 Arbitrator. The arbitrator shall be one (1) neutral, independent and impartial arbitrator selected from a pool of retired federal judges to be presented to the Parties by JAMS. Failing the agreement of the Parties as to the selection of the arbitrator within thirty (30) days, the arbitrator shall be appointed by JAMS in accordance with the JAMS Rules.

     14.4 Governing Law. Resolution of all disputes arising out of or related to this Agreement or the validity, construction, interpretation, enforcement, breach, performance, application or termination of this Agreement and any remedies relating thereto, shall be governed by and construed under the substantive laws of the Commonwealth of Massachusetts, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

     14.5 Decision. The power of the arbitrator to fashion procedures and remedies within the scope of this Agreement is recognized by the Parties as essential to the success of the arbitration process. The arbitrator shall not have the authority to fashion remedies which would not be available to a federal judge hearing the same dispute. The arbitrator is encouraged to operate on this premise in an effort to reach a fair and just decision. Reasons for the arbitrator’s decisions should be complete and explicit, including all determinations of law and fact. The written reasons should also include the basis for any damages awarded and a statement of how the damages were calculated. Such a written decision shall be rendered by the arbitrator following a full comprehensive hearing, no later than twelve (12) months following the selection of the arbitrator as provided for in Section 14.3.

     14.6 Award. Any award shall be promptly paid in United States dollars free of any tax; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting enforcement. If as to any issue the arbitrator should determine under the applicable law that the position taken by a Party is frivolous or otherwise irresponsible or that any wrongdoing they find is in callous disregard of law and equity or the rights of the other Party, the arbitrator shall also award an appropriate allocation of the adversary’s reasonable attorney fees, costs and expenses to be paid by the offending Party, the precise sums to be determined after a bill of attorney fees, expenses and costs consistent with such award has been presented following the award on the merits. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 14, and agrees that, subject to the Federal Arbitration Act, judgment may be entered upon the final award in the Federal District Court for the District of Massachusetts and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of the award until paid in full, at a rate fixed by the arbitrator. With respect to money damages, nothing contained herein shall be construed to permit the arbitrator or any court or any other forum to award punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages.

     14.7 Costs. Except as set forth in Section 14.6, each Party shall bear its own legal fees. The arbitrator shall assess his or her costs, fees and expenses against the Party losing the arbitration unless he or she believes that neither Party is the clear loser, in which case the arbitrator shall divide his or her fees, costs and expenses according to his or her sole discretion.

779758 v7/HN

49


     14.8 Injunctive Relief. Provided a Party has made a sufficient showing under the rules and standards set forth in the Federal Rules of Civil Procedure and applicable case law, the arbitrator shall have the freedom to invoke, and the Parties agree to abide by, injunctive measures after either Party submits in writing for arbitration claims requiring immediate relief. Additionally, nothing in this Article 14 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.

     14.9 Confidentiality. The arbitration proceeding shall be confidential and the arbitrator shall issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by law, including without limitation, securities law, no Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of the arbitrator without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the Parties and the arbitrator, except as required in connection with the enforcement of such award or as otherwise required by applicable law including without limitation, securities law.

     14.10 Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

     14.11 Jurisdiction. For the purposes of this Article 14, the Parties agree to accept the jurisdiction of the Federal District Court for the District of Massachusetts for the purposes of enforcing or appealing any awards entered pursuant to this Article 14 and for enforcing the agreements reflected in this Article 14 and agree not to commence any action, suit or proceeding related thereto except in such courts.

     14.12 Patent and Trademark Disputes. Any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Collaboration Patents or Marks covering the manufacture, use, importation, offer for sale or sale of Products shall be submitted to a court of competent jurisdiction in the country in which such patent or trademark rights were granted or arose.

779758 v7/HN


EXHIBIT A

FINANCIAL TERMS FOR CALCULATING ALLOWABLE EXPENSES

"Product Profit" for the Territory shall be determined in the manner specified in the Agreement and in this Exhibit A. The calculation of Allowable Expenses shall be determined according to the defined financial terms and the allocation mechanism set forth in this Exhibit A.

As used herein, the term “operating unit” shall mean the smallest operating unit in which an operating profit and loss statement is prepared for management accounting purposes in the Party’s normal accounting procedures, consistently applied within and across its operating units.

1.      COST OF GOODS SOLD
 
  1.1 “Cost of Goods Sold” means the cost of Product for the Territory shipped in
 

either bulk or final therapeutic form, as the Parties may then agree. The costs of manufacturing shall be calculated in accordance with reasonable cost accounting methods, consistently applied, of the Party performing the work, and shall consist of the following components: (a) direct costs, including manufacturing labor and materials directly used in manufacturing Products by CRXX or its Affiliates and allocated supervisory costs of the manufacturing department; (b) direct labor and allocated supervisory costs of non-manufacturing departments (such as quality and regulatory) attributable to such Products; (c) an allocation of depreciation of facilities, machinery and equipment used in manufacture of Products, provided that any idle capacity in the facility where the Compounds or Products are manufactured shall not be allocated to be included in the calculation of Costs of Goods Sold hereunder; (d) toll process and other charges incurred by CRXX or its Affiliates for outsourcing the manufacture of the Products and the cost of supervising and managing the Third Party manufacturers, and of receipt, incoming inspections, storage, packaging, handling quality control testing and release of the outsourced items; and (e) any other reasonable and customary out-of-pocket costs borne by such Party or its Affiliates for the testing, transport, customs clearance, duty.

     The cost of Product manufactured by Third Parties for the Territory shall equal the manufacturing Party's actual costs therefor.

2. MARKETING EXPENSES

     Marketing Expenses shall be the sum of Selling Expenses, Marketing Management, Market and Consumer Research, Advertising, Trade Promotion, Consumer Promotion, and Education Expenses, each of which is specified below, and all other costs which are consistent with the Commercialization Plan and attributable to the sale, promotion or marketing of Products in the Territory.

     2.1 “Selling Expenses” shall mean all costs and expenses directly associated with the efforts of field sales representatives with respect to Products in the Territory, including field sales force (including field sales managers); field sales offices; home offices staffs directly and to the extent involved in the management of and the performance of the selling

779758 v7/HN


functions; and payments to Third Parties under any agreements approved by the JSC. Reasonable field samples shall normally be charged to Trade Promotion, but if sales management has direct decision making authority for the distribution of field sales samples, it may be appropriate to charge these costs to Selling Expenses. The costs of detailing sales calls shall be allocated based on field force time at an accounting charge rate reasonably and consistently applied within and across its operating units and which is no less favorable to the Products than the internal charge rate used by CRXX for its own internal cost accounting purposes for products other than Products (excluding internal profit margins and markups).

     2.2 “Marketing Management” shall include product management and sales promotion management compensation and departmental expenses, including product related public relations, relationships with opinion leaders and professional societies, health care economics studies, contract pricing and administration, market information systems, governmental affairs activities for reimbursement, formulary acceptance and other activities directly related to the Products in the Territory, management and administration of managed care and national accounts, and other activities associated with developing overall sales and marketing strategies and planning for Products in the Territory. In addition, payments to Third Parties in connection with trademark selection, filing, prosecution and enforcement for Products in the Territory shall be included in this category. Such costs may be allocated on a percent of sales or other basis reasonably and consistently applied within and across its operating units and which is no less favorable to the Products than the internal allocation for CRXX's other products.

     2.3 “Market and Consumer Research” shall include compensation and departmental expenses for market and consumer research personnel and payments to Third Parties related to and to the extent use for conducting and monitoring professional and consumer appraisals of existing, new or proposed Products in the Territory such as market share services (e.g., IMS data), and special research testing and focus groups. Expenditures not directly related to a product may be allocated on a percent of sales or other basis reasonably and consistently applied within and across its operating units and which is no less favorable to the Products than the internal allocation for CRXX's other products.

     2.4 “Advertising” shall mean all costs reasonably incurred for the advertising and promotion of Products in the Territory through any means, including, without limitation, (i) television and radio advertisements; (ii) advertisements appearing in journals, newspapers, magazines, websites or other media; (iii) seminars and conventions; (iv) packaging design;

(v)      professional education programs; (vi) samples, visual aids and other selling materials;
 
(vii)      hospital formulary committee presentations; (viii) presentations to state and other
 

governmental formulary committees, and (ix) all media costs associated with Product advertising as follows: production expense/artwork including set up; design and art work for an advertisement; the cost of securing print space, air time, etc. in newspapers, magazines, websites, trade journals, television, radio, billboards, etc.

     2.5 “Trade Promotion” shall include the actual allowances given to retailers, brokers, distributors, hospital buying groups, etc. for purchasing, promoting, and distribution of Products in the Territory. This shall include purchasing, advertising, new distribution, and display allowances as well as free goods, wholesale allowances and reasonable field sales samples (at the out of pocket cost). To the extent multiple products are involved and some of such products are not Products, then such allowances shall be allocated on a pro rata basis

779758 v7/HN

A-2


based upon net sales of each respective product by such operating unit during the most recent quarter.

     2.6 “Consumer Promotion” shall include the expenses associated with programs to promote Products directly to the end user in the Territory. This category shall include expenses associated with promoting products directly to the professional community such as professional samples, professional literature, promotional material costs, patient aids and detailing aids. To the extent multiple products are involved and some of such products are not Products, then such allowances shall be allocated on a pro rata basis based upon net sales of each respective product by such operating unit during the most recent quarter.

     2.7 “Education” shall include expenses associated with professional education with respect to Products in the Territory through any means not covered above, including articles appearing in journals, newspapers, magazines or other media; seminars, scientific exhibits, and conventions; and symposia, advisory boards and opinion leader development activities.

3. DISTRIBUTION EXPENSES

     “Distribution Expenses” means all costs incurred by a Party to distribute Product in the Territory.

4. POST-LAUNCH PRODUCT R&D EXPENSES

     Post-Launch Product R&D Expenses shall include certain research and Development costs incurred by a Party in relation to a Product in the Territory after the First Commercial Sale and shall exclude administrative expenses and costs that are included within Costs of Goods Sold or Development Costs. Such post-launch research and Development costs shall include:

4.1      Phase 4 Clinical Trials.
 
4.2      Ongoing product support.
 
4.3      Ongoing medical affairs.
 
4.4      Contract R&D costs performed by others for a particular project that are
 

primarily related to the Development or Commercialization of a Product.

     4.5 Fees and expenses of outside counsel or consultants in respect of regulatory affairs unrelated to obtaining Regulatory Approvals.

5. PATENT EXPENSES

     “Patent Expenses” means the fees and expenses of outside counsel and payments to Third Parties incurred after the Effective Date in connection with the preparation, filing, prosecution and maintenance of PGx Patents, CRXX Patents, and/or Joint Patents in the Territory that cover Products or their manufacture or use, including the costs of patent interference and opposition proceedings.

779758 v7/HN

A-3


6. REGULATORY EXPENSES

     “Regulatory Expenses” means all costs incurred by a Party to comply with all Regulatory Approvals and all Regulatory Authorities, including FDA user and other fees, reporting, and other regulatory affairs activities for Product in the Territory.

9. NO DUPLICATION. No item of cost shall be duplicated in any of the categories comprising Allowance Expenses or in the deductions permitted under Net Sales.
