Good Manufacturing Practices, to attempt to achieve their objectives efficiently and expeditiously. 
  
 4.4 Development of Backup Compounds. All costs approved by the JSC, pursuant to Section 2.4, and directly related to the Development of any
Backup Compounds designated as Development Compounds in accordance with Section 4.5 shall be considered Development Costs, and shall be divided equally between the Parties pursuant to Section 4.9.  
  
 4.5 Designation of Development Compounds. As of the Effective
Date, ARC 183 has been designated as a Development Compound. The Parties shall seek to pursue the Development of at least one Development Compound at all times throughout the duration of the Agreement. The JSC shall have the right to designate any
Backup Compound as a Development Compound pursuant to this Section 4.5. The designation of a Backup Compound as a Development Compound shall be based on a therapeutic level of anti-thrombin activity at levels specified by the JSC, and such other
criteria as the JSC specifies. Once a Back-up Compound has been designated as a Development Compound, IND-enabling studies shall be pursued with the ultimate goal of obtaining Regulatory Approval of that Development Compound. 
  
 4.6 Abandonment of Development Compounds. Any time after a
Back-up Compound has been designated as a Development Compound, the JSC may determine that Development of such Development Compound should be abandoned. If the JSC decides, pursuant to Section 2.4, to abandon Development of a particular Development
Compound, then neither Party shall thereafter continue such Development within the Field without the consent of the other Party. If the Parties are able to out-license the abandoned Development Compound, the proceeds of such out-licensing shall be
treated as Licensing Revenue to be shared equally by the Parties. 
  
 4.7 Regulatory Affairs. 
  
 (a) Consistent with the Development Plan and Budget, but subject to the remainder of this Section 4.7, the “Lead Regulatory Party” shall be designated by the JSC, pursuant to Section 2.4; but, Nuvelo shall not be
designated the Lead Regulatory Party without its consent. The responsibilities of the Lead Regulatory Party shall be as follows: 
  
 (i) developing pre-NDA Regulatory Documentation and preparing and submitting pre-NDA Regulatory Filings, seeking Pre-NDA Regulatory
Approvals, and maintaining pre-NDA Regulatory Approvals for Collaboration Products, including preparing all reports necessary as part of an IND, DMF, BLA or other necessary filing required for Pre-NDA Regulatory Approvals; and 
  

 19. 

 (ii) developing NDA Regulatory Documentation and preparing and submitting NDAs for
Collaboration Products, seeking Regulatory Approvals, and maintaining Regulatory Approvals for Collaboration Products, including preparing all reports necessary as part of an NDA, DMF, BLA or other necessary filing required for Regulatory Approval.

Regulatory Documentation and Regulatory Filings, each Party shall permit the other Party to access, and shall provide the other Party with sufficient rights to reference and use in association with exercising its rights and performing its
obligations under this Agreement, all of its, its affiliates’ and their respective suppliers’ Regulatory Documents, Regulatory Filings, and Regulatory Approvals for Collaboration Products. 
  
 (c) The Lead Regulatory Party shall keep the other
Party informed on an ongoing basis regarding the schedule and process for Regulatory Documents and Regulatory Filings and give the other Party the ability to participate in the preparation of Regulatory Documents and Regulatory Filings and shall
provide the other Party with reasonable advance notice of any meeting or substantive telephone conference call with any Regulatory Authority relating to any Regulatory Documents and Regulatory Filing. The other Party shall have the right to
participate with the Lead Regulatory Party in any such meeting or conference call. The Lead Regulatory Party shall promptly furnish the other Party with copies of all correspondence that the Lead Regulatory Party receives from any Regulatory
Authority, and contact reports it receives concerning substantive conversations or substantive meetings with any Regulatory Authority, in each case relating to any such Regulatory Filings. The Lead Regulatory Party shall prepare all responses to
correspondence that are received from any Regulatory Authority relating to any Regulatory Documents and any Regulatory Filing. The other Party shall be provided with advance notice of any such responses and shall be given an opportunity to comment.

  
 (d) In conducting any Development
activities hereunder, each Party shall: (a) ensure that its employees, agents, clinical institutions and clinical investigators comply with all FDA statutory and regulatory requirements with respect to Collaboration Products, including but not
limited to: the Federal Food, Drug and Cosmetic Act, as amended (FFDCA), the Public Health Service Act (PHSA), regulatory provisions regarding protection of human subjects, financial disclosure by clinical investigators, Institutional Review Boards
(IRB), Good Clinical Practices, Good Laboratory Practices, IND regulations, and any conditions imposed by a reviewing IRB or the FDA; and (b) not utilize, in conducting studies on Collaboration Products any person or entities that at such time are
debarred by the FDA, or that, at such time, are under investigation by the FDA for debarment action pursuant to the provisions of the Generic Drug Enforcement Act of 1992 (21 U.S.C. Section 335). 
  
 (e) Each Party shall maintain a record of all
non-medical and medical product-related complaints and reports of adverse events that it receives with respect to any Collaboration Product. Each Party shall notify the other Party of any complaint received by it and, within 15 days after the
initial receipt, provide the other Party with a copy of such complaint(s) and adverse event reports. The Lead Regulatory Party shall be responsible for reporting to Regulatory Authorities any adverse experiences and safety issues for such
Collaboration Product in compliance with the requirements of the U.S. Food, Drug and Cosmetic Act, 21 U.S.C. § 321 et seq., the regulations promulgated thereunder, and equivalent foreign 

  

 20. 

 
laws, rules and regulations. The Lead Regulatory Party shall promptly thereafter provide the other Party with a copy of each such report. 
  
 (f) The Lead Regulatory Party shall cooperate to
effect a timely and efficient transfer of regulatory responsibilities at such time as the other Party is designed Lead Regulatory Party as provided in this Article 4. 
  
 4.8 Reports. At each meeting of the JSC, each Party shall report to the JSC the work it has performed under
the Development Plan and Budget since the previous meeting. 
  
 4.9 Research Costs and Development Costs; Reporting and Reimbursement. 
  
 (a) Except as provided in Section 4.9(b) and 4.9(c), each Party shall bear one half of all Research Costs and one half of all
Development Costs directly related to the program and approved by the JSC pursuant to Section 2.4.  
  
 (b) Within 30 days after the end of each calendar quarter, each Party shall submit to the other Party an accounting of all Research
Costs and Development Costs incurred by the reporting Party during that quarter, including reasonable detail demonstrating the specific basis for the costs and expenses included in the summary. Nuvelo shall on a quarterly basis, within 45 days after
the end of each calendar quarter (if Archemix submitted its accounting report on time), prepare and submit to Archemix a reconciliation of the Research Costs and Development Costs of each Party, and provide for a balancing payment as follows:

  
 (i) Until the aggregate Research Costs
and Development Costs incurred by the Parties under this Agreement (inclusive of the costs reimbursed by Nuvelo pursuant to Section 4.9(c)) equals $4,000,000, Nuvelo shall reimburse to Archemix, by wire transfer of immediately available funds
accompanying the quarterly reconciliation statements, Archemix’ Research Costs and Development Costs for the quarter. 
  
 (ii) After the aggregate Research Costs and Development Costs reach $4,000,000: 
  
 (1) if for a particular calendar quarter the sum of
Archemix’ Research Costs and Development Costs are greater than the sum of Nuvelo’s Research Costs and Development Costs, then Nuvelo shall send Archemix a payment by wire transfer of immediately available funds totaling 1/2 of the
difference; and 
  
 (2) if the sum of
Nuvelo’s Research Costs and Development Costs are greater than the sum of Archemix’ Research Costs and Development Costs, Nuvelo shall send Archemix an invoice for an amount equal to 1/2 of the difference and Archemix shall remit to Nuvelo
by wire transfer of immediately available funds the amount of such invoice within 20 days after receiving such invoice. 
  
 (c) Costs Incurred before the Effective Date. 
  
 (i) Within 30 days after the Effective Date, Nuvelo will reimburse Archemix for Research Costs and
Development Costs directly related to the Collaboration and 

  

 21. 

 
that Archemix has incurred between September 10, 2003 and December 31, 2003, subject to the limit on costs incurred before the Effective Date set forth in
subsection 4.9(c)(iii). Archemix shall submit an invoice to Nuvelo for such reimbursement, together with reasonable detail demonstrating the specific basis for the costs and expenses included in the invoice, and Nuvelo shall remit to Archemix by
wire transfer of immediately available funds the amount on such invoice submitted by Archemix within 20 days after receiving such invoice. 
  
 (ii) Any Research Costs and Development Costs directly related to the Collaboration that Archemix has incurred between January 1,
2004 and the Effective Date shall be paid to Archemix in accordance with the provisions of Sections 4.9(a) and 4.9(b), but expressly subject to the limit on costs incurred before the Effective Date set forth in subsection 4.9(c)(iii). 
  
 (iii) Notwithstanding anything else in this
Agreement, the total amount of costs incurred by Archemix before the Effective Date for which Nuvelo shall be responsible shall not exceed $750,000. 
  
 (d) Costs incurred in Research and Development activities under this Agreement in excess of the amounts permitted in accordance
with Section 3.2(d) and Section 4.1(c) shall not be treated as Research Costs or Development Costs and shall not be reimbursed, except with subsequent approval of the JSC. 
  
 (e) If a disagreement arises about the amount due under this Section 4.9, each Party shall promptly
notify the other, and the Parties shall endeavor to promptly resolve such dispute, but in no event shall the resolution of such dispute exceed twenty (20) days. Until such dispute is resolved, Nuvelo shall report and provide for payments excluding
any disputed costs. Either Party may audit, in accordance with the procedures set forth in Article 9, the accuracy of the other Party’s submissions under this Section 4.9(e). 
  

	5.	COMMERCIALIZATION 

  
 5.1 Commercialization Decision. 
  
 (a) The JSC shall seek to determine, with respect to each Collaboration Product, whether such Collaboration Product should be
Commercialized directly (by one or more of the Parties—meaning that such Party will itself be responsible for selling such Product at least in the United States, although Third Parties may be engaged for various aspects of Commercialization in
the United States as well as other markets) or indirectly (meaning that Commercialization shall occur exclusively through Third Parties, under one or more licensing agreements), but if the JSC is unable to reach agreement, then the Collaboration
Product shall be Commercialized directly, provided that the Party that favors direct Commercialization has the capability and desire to function as the Lead Marketing Party as set forth in this Article 5, otherwise the Collaboration Product shall be
Commercialized indirectly. As used herein, the former structure is referred to as “Direct Commercialization” (even though Third Parties are likely to be selling the Commercialization Product outside the United States) and the latter
structure is referred to as “Partnered Commercialization.” 
  

 22. 

 (b) In deciding between Direct Commercialization and Partnered Commercialization,
the JSC shall be guided by the principle of profit maximization. At any time beginning with the completion of the first Phase 2 clinical trial of a Development Compound and no later than 6 months before the filing of an NDA for such Collaboration
Product, either Party may request that the JSC make its decision regarding whether the product in question will be the subject of Direct Commercialization or Partnered Commercialization. No specific time limit shall apply to reaching agreement on
such matter, except that if the Parties cannot agree on this decision by the time of approximately 6 months before filing of an NDA for the Collaboration Product, then the decision as to whether to market the Collaboration Product using Direct
Commercialization or Partnered Commercialization shall be governed by Section 5.1(a). 
  
 5.2 Lead Marketing Party. The Party that leads Direct Commercialization of a Collaboration Product in accordance with this Section 5.2 is referred to in this Agreement as the “Lead Marketing
Party”. Nuvelo, at its option and in its sole discretion, may elect to be the Lead Marketing Party for any or all of the Collaboration Products so long as, previous to its election, Nuvelo has established Commercialization capabilities,
including the existence of an internal trained sales force, that will allow Nuvelo to carry out the responsibilities associated with the Lead Marketing Party as set forth in this Article 5. If Nuvelo does not elect to be the Lead Marketing Party for
a particular Collaboration Product then Archemix shall be the Lead Marketing Party for the particular Collaboration Product. If Archemix does not want to be Lead Marketing Party for the Collaboration Product, the Collaboration Product shall be
commercialized through Partnered Commercialization in accordance with Section 5.14. The Lead Marketing Party shall have the responsibilities set forth in this Article 5, but shall remain subject to the decision making authority of the JSC as
provided in this Article 5. The Lead Marketing Party shall determine whether to allocate any Commercialization responsibilities to the other Party under this Agreement (except to the extent the other Party participates through the JSC), but shall
have no obligation to allocate any responsibilities to the other Party, and the other Party shall have no obligation to participate directly in Commercialization except with its consent. 
  
 5.3 Co-Promotion of Collaboration Products. With respect to any Collaboration Product, if a Collaboration
Product is being Commercialized through Direct Commercialization, the Party that is not the Lead Marketing Party has a right, but not an obligation, to reasonably participate in the Commercialization of such Collaboration Product. At any time during
the Term, the Party that is not the Lead Marketing Party may notify the Lead Marketing Party in writing of its decision to reasonably participate in Commercialization of the applicable Collaboration Product. Upon the Lead Marketing Party’s
receipt of notice thereof, the Parties shall negotiate in good faith for the reasonable participation of the other Party in the Commercialization of the Collaboration Product, with both Parties sharing equally the profits and losses of such
Commercialization. If the Parties cannot reach agreement within 90 days after the Lead Marketing Party’s receipt of the other Party’s written notice, either Party may elect to have the issue resolved in accordance with the dispute
resolution provisions set forth in Article 16. 
  
 5.4
Responsibilities of the JSC During Commercialization. The JSC shall: (a) oversee the Commercialization of Collaboration Products, including: the planning, annual budgeting, manufacturing, marketing, sales and distribution and
sub-licensing of Collaboration 

  

 23. 

 
Products; (b) monitor, review and comment on costs incurred by the Parties in the commercial manufacture, marketing, sale and distribution of Collaboration
Products; (c) review and approve the Commercialization Plans and Budgets and Launch Plans and Budgets and the selection of trademarks for Collaboration Products; (d) receive and provide to the Parties all sales, pricing, and financial reports
pertaining to Commercialization of Collaboration Products; (e) determine the price for Collaboration Products pursuant to Section 5.10; (f) facilitate the flow of Information with respect to the Commercialization of each Collaboration Product; and
(g) determine the overall pricing strategy for a particular Collaboration Product at least 90 days before commercial launch of such product. Notwithstanding anything else in this Article 5, if the JSC fails to reach unanimous agreement as to any
matter involving Commercialization as set forth in this Section 5.4, the Lead Marketing Party (if a Lead Marketing Party has been established in accordance with Section 5.2) shall make the final decision. 
  
 5.5 Commercialization Plan and Budget. 
  
 (a) The Lead Marketing Party shall develop a
comprehensive written plan and budget for the direct development and commercialization of the Collaboration Product in the Field (a “Commercialization Plan and Budget”). The Commercialization Plan and Budget will set forth in detail
the marketing, sale and distribution activities to be undertaken with respect to such Collaboration Product (including advertising, education, planning, marketing, sales force training and distribution), as well as the activities required for the
manufacture of such Collaboration Products following commercial launch, in each case whether such activities are undertaken before or after Regulatory Approval. The Commercialization Plan and Budget shall include but not be limited to: (i)
demographics, market dynamics and market strategies, estimated country launch dates, a sales forecast (including at least three (3) years of estimated sales), manufacturing plans and expected product profile based upon the Development Plan and
Budget; and (ii) a market plan (including pricing strategies pertaining to discounts, and samples), it being understood that the market plan will evolve over time. 
  
 (b) The Commercialization Plan and Budget shall include a budget of the expenses expected to be
incurred in connection with performing such Commercialization Plan and Budget, and shall set forth the maximum Allowable Commercialization Expenses to be incurred in each calendar year (although some of such expenses may be expressed as a percentage
of revenue or other mutually-agreed formulas). In those territories where the Collaboration Product will be sold through Third Party licensees, the Commercialization Plan and Budget may be limited to solely those activities for which the Lead
Marketing Party will be responsible. 
  
 (c)
By September 1 of each calendar year, the Lead Marketing Party shall prepare and submit to the JSC a draft Commercialization Plan and Budget for the forthcoming year. The Party other than the Lead Marketing Party shall submit its comments on
such draft plan and budget within 30 days after its receipt, and the JSC shall thereafter meet and confer, with the objective of approving such Commercialization Plan and Budget as soon as practicable, and no later than November 15. It is understood
that Commercialization Plans and Budgets may need to change in the course of a calendar year, and if the Lead Marketing Party determines that such a change may be necessary, it shall promptly inform the JSC and the JSC shall promptly decide such
matter. 
  

 24. 

 5.6 Launch Plan and Budget. 
  
 (a) Each Commercialization Plan and Budget shall include, in advance of the launch of the applicable
Collaboration Product, a plan and budget for the product launch and the 12 month period following the launch date (the “Launch Plan and Budget”). Each Launch Plan and Budget shall be developed by the Lead Marketing Party and
approved by the JSC. The Launch Plan and Budget shall be included in the Commercialization Plan and Budget for the year such launch occurs. 
  
 (b) It is understood that determining a date for Regulatory Approval and thus launch date is difficult. The failure to accurately
estimate the launch date shall not constitute a breach hereunder. As a result of this uncertainty, the JSC shall estimate for each country a realistic date for Regulatory Approval, and the Lead Marketing Party will use this estimated date to prepare
its Launch Plan at least 12 months before the estimated Regulatory Approval. Any Launch Plan and Budget which has not yet been executed shall be updated by the Lead Marketing Party at least on the schedule set forth above in Section 5.5(c). 

  
 (c) Each Launch Plan and Budget shall
include a breakdown of individual Allowable Commercialization Expenses expected to be incurred in connection with performance pursuant to the applicable Launch Plan and Budget. 
  
 5.7 Right to Engage Third Parties. The Lead Marketing Party may engage Third Parties to assist with the
Commercialization of a Collaboration Product. The costs of engaging any such Third Party will be Allowable Commercialization Expenses to the extent that the engagement of the applicable Third Party is consistent with the Commercialization Plan and
Budget. 
  
 5.8 Commercialization Efforts. Each
Party shall use Diligent Efforts to carry out its obligations under the Commercialization Plan and Budget and the Launch Plan and Budget within the approved budgets and to cooperate with each other in carrying out the Commercialization Plan and
Budget. 
  
 5.9 Advertising and Education; Trademarks.

  
 (a) The Lead Marketing Party shall
be responsible for developing or having developed advertising and education materials for Collaboration Products. The Parties shall jointly select trademarks for the Collaboration Product and shall jointly own all such trademarks. Neither Party may
use any trademark for a Collaboration Product for any purpose other than Commercializing the Collaboration Product, except if such trademark is transferred to it pursuant to Section 13.2. 
  
 (b) If any written and visual promotion or
educational materials for a Collaboration Product refer to or identify either of the Parties, Nuvelo and Archemix shall both be presented and described with equal prominence. All product labeling, documentary information, promotional material and
oral presentations (where practical) regarding the detailing and promoting of Collaboration Products shall display the names and logos of both Parties with equal prominence. Any such materials that specifically refer to the Parties shall be 

  

 25. 

 
subject to prompt prior review and comment by both Parties, such review and comment not to be unreasonably withheld or delayed.  
  
 (c) Notwithstanding the foregoing, subsections (a)
and (b) above are subject to the requirements of applicable laws and regulations of each country in which such materials are presented or in which Collaboration Products are Commercialized. 
  
 5.10 Pricing Approvals and Product Distribution. The Lead
Marketing Party shall obtain such Collaboration Products approvals as may be required and arrange for distribution of each Collaboration Product in each applicable country. 
  
 5.11 Product Recalls. In the event that any Regulatory Authority schedules an inspection, threatens or
initiates any action to remove a Collaboration Product from the market, the party that receives such communication shall notify the other Party of such communication within one business day of receipt. If either Party believes that a recall of a
Collaboration Product is necessary, such Party shall notify and consult with the other Party within 2 working days after its determination and both Parties shall cooperate to allow such recall to occur under the direction of the Lead Marketing
Party. In the event of a dispute about whether to recall a Collaboration Product, such recall shall occur. The expenses of a Collaboration Product recall shall be an Allowable Expense shared by the Parties, except to the extent one Party is
responsible for such expense pursuant to Article 15. For the purposes of this Section 5.11, “Recall” means: (a) any action by either Party, or any Affiliate or subsidiary of any Party, to recover title to or possession of a
Collaboration Product sold or shipped to Third Parties; or (b) the failure by either Party to sell or ship a Collaboration Product to Third Parties that would have been subject to recall if it had been sold or shipped. 
  
 5.12 Sales and Inventory. The Lead Marketing Party shall be
responsible for booking sales, stocking inventory for itself and its sublicensees, and collecting accounts receivable. Any cost incurred in such activities, including without limitation lost material or bad debt, may be recoverable as provided under
Allowable Commercialization Expenses.  
  
 5.13
Product Profits and Loss. Nuvelo and Archemix shall share equally in Product Profit and Loss hereunder with respect to each Collaboration Product, as further provided in Section 8.5, until each Collaboration Product is permanently
withdrawn and is no longer being sold anywhere. 
  
 5.14
Partnered Commercialization. 
  
 (a)
If the Parties enter into Partnered Commercialization in accordance with Section 5.1 or Section 5.2, the responsibilities of the JSC shall include, without limitation: (i) identifying potential partners; (ii) designating one or more potential
partners to engage in negotiations; and (iii) assigning one or both Parties with the responsibility of taking the lead in such negotiations. The Party leading the negotiations shall keep the other Party informed through the JSC regarding such
activities and negotiations. 
  
 (b) Any
Partnering Agreement must be approved by both Parties. The Parties recognize that a Partnering Agreement with a Third Party Partner for the Commercialization of a Collaboration Product will require the Parties to incur Partnering Costs, both in the
identification 

  

 26. 

 
of the Third Party contractors and during the contracting process, and possible ongoing activities thereafter. Such Partnering Costs shall be an element of
Product Profit and Loss, and reimbursed accordingly. 
  
 5.15
Progress Report. On or before February 28 and August 30 of each year, commencing as of August 30, 2004, and ending on February 28 of the calendar year following the calendar year in which the Lead Marketing Party, its Affiliates or
sublicensees first begins to market any product or service utilizing the Archemix Patents, the Lead Marketing Party shall provide a semi-annual progress report to the other Party, each report covering the 6 month period preceding the due date of the
report. Thereafter, the Lead Marketing Party shall provide such reports on an annual basis covering the 12 month period preceding the due date of the report. Each report shall describe the progress made by the Lead Marketing Party, its Affiliates or
sublicensees toward the commercial development of any Collaboration Compounds and Collaboration Products utilizing the Archemix Patents. Such report shall include, at a minimum, information reasonably sufficient to enable the other Party to
determine that the Lead Marketing Party is using Diligent Efforts in the Commercialization of any Collaboration Compounds and Collaboration Products. With regard to any product or service utilizing the Archemix Patents, until such time as a Lead
Marketing Party is designated for such product or service, on or before February 28 and August 30 of each year, commencing as of August 30, 2004, and ending upon the designation of a Lead Marketing Party, the JSC shall prepare a semi-annual progress
report for the Parties, each report covering the 6 month period preceding the due date of the report. Each report shall describe the progress made toward the commercial development of any Collaboration Compounds and Collaboration Products utilizing
the Archemix Patents. Such report shall include, at a minimum, information reasonably sufficient to enable the Parties to determine whether they are using Diligent Efforts in the Commercialization of any Collaboration Compounds and Collaboration
Products. 
  

	6.	MANUFACTURING AND SUPPLY 

  

6.1 Lead Manufacturing Party. “Lead Manufacturing Party” means: (a) the Lead Development Party with respect to the
manufacture of preclinical and clinical materials for a Collaboration Compound; and (b) the Lead Marketing Party with respect to the commercial manufacture of a Collaboration Product. 
  
 6.2 Clinical Materials. The Parties acknowledge that Archemix has contracted with a Third Party for the
manufacture of preclinical and clinical materials for the Development Compound. Within 90 days after the Effective Date, the JSC shall evaluate the current Third Party manufacturer of the Development Compound and decide whether the Parties should
replace the Third Party manufacturer. If the JSC decides that the current Third Party Manufacturer should be replaced, the Lead Manufacturing Party shall identify the major issues in the decision, the anticipated requirements for Collaboration
Compound manufacture, and the leading Third Party candidates for supply. In the event that the JSC replaces the current Third Party manufacturer, any costs incurred as a result of terminating the contract with the Third Party manufacturer and
negotiating a different supply agreement with the new Third Party manufacturer shall be considered Research Costs and Development Costs for purposes of Article 4. The JSC shall determine whether and from whom to solicit competitive bids for
pre-clinical and clinical supply. The Lead Manufacturing Party shall be responsible for negotiating a 

  

 27. 

 
separate supply agreement with the JSC approved Third Party Manufacturer for preclinical and clinical supply of any Collaboration Compound, subject, however,
to final approval by the JSC. Such supply agreement shall be executed by both Parties as well as the Third Party Manufacturer. 
  
 6.3 Commercial Supply. At any time after the Effective Date but before the Commencement of the first Phase 3 Trial in connection with any
Collaboration Product, the JSC shall determine which Third Party entity shall be selected as the commercial manufacturer of the Collaboration Product. The Lead Marketing Party shall identify the major issues in the decision, the anticipated
requirements for Product manufacture, and the leading Third Party candidates for supply. The JSC shall determine whether and from whom to solicit competitive bids for commercial supply. The Lead Marketing Party shall be responsible for negotiating a
separate supply agreement for commercial supply with the JSC approved Third Party Manufacturer, subject, however, to final approval by the JSC. Such supply agreement shall be executed by both Parties as well as the Third Party Manufacturer.

  
 6.4 Manufacturing Approvals. Under the
supervision of the JSC, the Parties shall use Diligent Efforts to make necessary filings to obtain, or to cause the then current Third Party manufacturer of Collaboration Products to make necessary filings to obtain, Regulatory Approval for the
manufacture of Collaboration Compounds and Collaboration Products as part of the approval of a Drug Approval Application for each Collaboration Product. Such filings shall include the filing and maintenance of a DMF in the United States and the
equivalent thereof in the other countries of the world in which the parties seek Regulatory Approval of Collaboration Products. 
  
 6.5 Specifications. The Parties agree that the manufacture of Collaboration Compounds and Collaboration Products must be in full compliance
with all aspects of then current GMPs. The Lead Manufacturing Party, initially, and thereafter the Third Party manufacturer shall prepare and submit to the JSC for its approval the specifications, including any necessary documentation, certificates
of analysis and test results, for the Collaboration Compounds and Collaboration Products to be manufactured by it under this Article 6. Changes in Specifications shall be made only upon the approval by the JSC. 
  
 6.6 Other Supply. Neither Party shall supply Collaboration
Compounds or Collaboration Products to any Third Party for any Third Party use without the prior consent of the other Party, except to the extent necessary to perform Research, Development or Commercialization activities under this Agreement. In
addition, neither Party shall license any Third Party to make or have made Collaboration Compounds or Collaboration Products, except with the approval of the JSC. 
  

	7.	LICENSES AND RELATED RIGHTS 

  
 7.1 License to Archemix. Subject to the terms of this Agreement, Nuvelo grants to Archemix a worldwide,

shall not: (i) independently or with a Third Party perform research activities specifically designed to identify and characterize any compound with a therapeutically useful level of anti-thrombin activity for use within the Field; (ii) perform
research, development, manufacture, importation or commercialization upon any human thrombin inhibitor for use within the Field; or (iii) license or otherwise enable any Third Party to perform any of the activities set forth in subsections (i) and
(ii) above. 
  
 (c) Aptamers Outside the
Collaboration. During the term of the Collaboration, Archemix may, in its sole discretion, present to the JSC any Aptamer that has a therapeutic level of anti-thrombin activity that is discovered by Archemix outside the Collaboration, and the JSC
shall determine whether such Aptamer shall be deemed a Backup Compound within 60 days of such presentation, whereupon the provisions of this Agreement shall apply to such Aptamer as if such Aptamer resulted from Research under the Collaboration.

  
 7.7 Third Party License Obligations. The JSC
shall be responsible for evaluating whether and when to enter into licensing agreements with Third Parties during the Collaboration. To the extent that any license fee, royalty or other payment obligation accrues under any license agreement between
Nuvelo or Archemix and a Third Party that is needed for the manufacture, use, sale or importation of a Collaboration Compound or Collaboration Product, responsibility for such payments shall be shared equally by the Parties. In the event that the
JSC elects not to enter into a license and such decision results in an enforcement action being brought against one or both of the Parties, any costs and liabilities that arise shall be shared equally by the Parties. 
  
 7.8 Third Party Royalties. Archemix warrants that the only
Third Party royalty obligation that exists as of the Effective Date with respect to the Archemix IP licensed to Nuvelo under this Agreement is set forth in the ULEHI Agreement. The royalty obligation set forth in this Section 7.8 shall be referred
to as the “Third Party Royalty”. 
  

 30. 

 7.9 Sharing of Data. 
  
 (a) During the Collaboration, both Parties shall have the right to access all Archemix Information
and Nuvelo Information as it is generated. 
  
 (b) The Parties’ access to Archemix Information and Nuvelo Information after the termination of the Collaboration shall be governed by Section 13.2(a). 
  

	8.	COMPENSATION 

  
 8.1 Upfront Payment. Nuvelo shall pay to Archemix $3,000,000 within 10 days after the Effective Date by wire transfer of immediately
available funds. 
  
 8.2 Phase 2 Milestone Payment.
Subject to the terms and conditions of this Agreement, Nuvelo shall pay to Archemix $10,000,000 within 10 days after the achievement of the Phase 2 Milestone.  
  
 8.3 Development Costs and Research Costs. Pursuant to Section 4.9(b), Nuvelo shall be responsible for the
first $4,000,000 of combined Research Costs and Development Costs, inclusive of the payments to be made under Section 4.9(c). 
  
 8.4 Backup Compound Reimbursement. Within 30 days after the JSC’s designation of any Backup Compound as a Development Compound pursuant
to Section 4.5, Nuvelo shall pay to Archemix $1,000,000. 
  
 8.5 Product Profit and Loss Allocation. The Parties shall share equally all Product Profit and Loss. 
  
 (a) Reporting and Reconciliation. 
  

(i) Within 30 days after the end of each calendar quarter following the first receipt of revenues under this Agreement (which
may be either from Net Sales or Licensing Revenue), each Party shall report to the other Party its revenues from such sources and its individual Allowable Commercialization Expenses (with appropriate supporting information) involved in the
computation of Product Profit and Loss and accrued during such quarter with respect to each such Collaboration Product. Such report shall present the computation of Product Profit and Loss on a: (i) cash basis of accounting; and (ii) an accrual
basis of accounting. Within 20 days after receipt of such reports, the Lead Marketing Party or Partnering Party, as the case may be, shall prepare and submit to the other Party a statement of quarterly Product Profit and Loss, in substantially the
form attached as Exhibit B, which shall include a calculation of the equalization payment which is necessary to cause each Party’s participation in the Product Profit and Loss for such quarter on a cash basis to be the same (the
“Financial Statement”). The reports and equalization payments for the fourth quarter of the fiscal year may include reconciliations and year-end adjustments with respect to previous quarters. All payments required by this Section
8.5(a) shall be made within 10 days after the submittal of the Financial Statement. Either Party may audit, in accordance with the procedures set forth in Article 9, the accuracy of the other Party’s submissions pursuant to this Section 8.5(a).

  
 (ii) By way of example, on a cash
basis, if during a particular quarter the Lead Marketing Party realized revenues from Collaboration Products of $100 million and 

  

 31. 

 
incurred Allowable Commercialization Expenses of $30 million, and the other Party realized no revenues from Collaboration Products and incurred Allowable
Commercialization Expenses of $10 million, then the Equalization Payment for such quarter would be a payment by the Lead Marketing Party to the other Party in the amount of $40 million. For purposes of clarity, the example set forth in this Section
8.5(a)(ii) is calculated on a cash basis of accounting. 
  
 8.6
Payment Method. All payments due under this Agreement to either Party shall be made by bank wire transfer in immediately available funds to an account designated by the receiving Party. All payments hereunder shall be made in U.S. dollars
from the United States. 
  
 8.7 Taxes. Each Party
shall pay any and all taxes levied on account of all payments it receives under this Agreement. If laws or regulations require that taxes be withheld, the paying Party will: (a) deduct those taxes from the remittable payment; (b) pay the taxes to
the proper taxing authority; and (c) send evidence of the obligation together with proof of tax payment to the receiving Party within 30 days following that tax payment. 
  
 9. RECORDS; AUDITS. Both Parties shall keep complete, true and accurate books of accounts and
records for the purpose of determining the payments to be made under this Agreement. Such books and records shall be kept for at least three (3) years following the end of the calendar quarter to which they pertain. Such records will be open for
inspection during such three (3) year period by independent accountants, solely for the purpose of verifying payment statements hereunder. Such inspections shall be made no more than once each calendar year, at reasonable time and on reasonable
notice. If any errors that favor the inspected Party are discovered in the course of such inspection, then within 30 days after its receipt of the inspection report, the inspected Party shall pay the inspecting Party those amounts (plus interest
equal to the Prime Lending Rate as published in the Wall Street Journal on the day preceding the inspection plus two hundred (200) basis points; provided, however, that in no event shall such rate exceed the maximum annual interest rate
permitted under applicable law) that the inspecting Party would have received in the absence of such errors. Inspections conducted under this Article 9 shall be at the expense of the inspecting Party, unless a variation or error that favors the
inspected Party exceeding 5% of the amount stated for any year covered by the inspection is established in the course of such inspection, whereupon all costs relating to the inspection for such period will be paid promptly by the inspected Party.

  

	10.	INFORMATION, INVENTIONS AND INTELLECTUAL PROPERTY 

 
 10.1 Ownership. 
  
 (a) Sole Inventions and Joint Inventions. All
Sole Inventions shall be the property of the sole inventing Party. All Joint Inventions shall be jointly owned by the Parties. Each Party’s rights and interests to Sole Inventions and Joint Inventions shall be the same as provided with respect
to Patents under United States law, and in particular, either Party may exploit or grant licenses under the Joint Inventions without a duty of accounting to the other Party, except as otherwise expressly specified in this Agreement. 
  

 32. 

 (b) Inventions Relating to SELEX Technology. The SELEX Inventions shall be
the property of Archemix. Nuvelo shall and hereby does assign to Archemix all of Nuvelo’s right, title and interest in and to all SELEX Inventions. 
  
 (c) Know-How. Ownership of any Collaboration Know-How shall be determined by treating such Know-How as if it were a Sole,
Joint or SELEX Invention, as appropriate under the circumstances and in accordance with the terms and conditions of this Agreement. Archemix shall Control the Archemix Know-How, and any Patent claiming Archemix Know-How shall be deemed to be an
Archemix Patent. Nuvelo shall Control the Nuvelo Know-How, and any Patent claiming the Nuvelo Know-How shall be deemed to be a Nuvelo Patent. 
  
 (d) Further Acts. Each Party shall perform such additional actions necessary to affect the intent of this Section 10.1, and
shall reasonably cooperate with the other Party in doing so. 
  
 10.2 Disclosure. Each Party shall submit a written report to the JSC within 30 days after the end of each quarter describing any Sole Invention, SELEX Invention, or Joint Invention arising during the prior quarter in the
course of the Collaboration, which it believes may be patentable. 
  
 10.3 Patent Prosecution and Maintenance.  
  
 (a) Sole Inventions. The Party owning a Sole Invention shall have the right but not the obligation to file, prosecute and maintain any Patent thereon. Such Party shall control the prosecution and bear
the costs of any such activities undertaken by itself or its agents with respect to a Sole Invention. If a Party elects not to file, prosecute or maintain any Patent in any country that claims a Sole Invention, then such Party shall notify the other
Party of such election promptly in writing, but in any event at least 45 days before the next required filing deadline, in order to maintain the availability of Patent protection for the Sole Invention. If after receiving any such notice, the other
Party responds with written notice that it wishes to take responsibility for such Patent in such country for the Sole Invention, then the Party that decided not to pursue such patent application or Patent shall: (i) promptly provide the other Party
with all pertinent files, correspondence, records, information and other documents relating thereto in its possession or control; and (ii) take all other actions reasonably necessary to transfer to the other Party (or its designee) the right, power
and authority to file, prosecute and maintain such Patent in such country. If such other Party assumes the filing, prosecution and maintenance of any Patent in any country pursuant to this Section 10.3(a), it shall be responsible for all expenses
incurred in connection with such activities. 
  
 (b) Joint Inventions. After receiving the disclosure of inventions from the Parties pursuant to Section 10.2, the JSC shall decide whether to file a patent application for a Joint Invention and, if so, which Party shall be
responsible for the filing, prosecution and maintenance of any Patent claiming the Joint Invention. Such responsible Party shall provide the other Party with: (i) drafts of any new patent application that covers such Joint Invention before filing
that application, allowing reasonable time for review and comment by the other Party; and (ii) copies of all correspondence from any and all Patent offices concerning any Patents claiming 

  

 33. 

 
the Joint Invention and an opportunity to comment on any proposed responses, voluntary amendments and submissions of any kind to be made to any and all such
Patent offices. If the JSC decides that a patent application on a Joint Invention shall be filed but cannot agree on which Party shall be responsible for the filing, prosecution and maintenance of that Patent, Archemix shall be the responsible Party
unless the Collaboration is terminated by Nuvelo in accordance with Section 13.1(a) or by Archemix in accordance with Section 13.1(b), in which case Nuvelo shall be the responsible Party. If the JSC decides that a patent application on a Joint
Invention shall not be filed such invention shall be considered Know-How jointly-owned by the Parties. If the JSC cannot agree on whether a patent application shall be filed on a Joint Invention, either Party may file a patent application on the
Joint Invention with the written consent of the other Party. 
  
 (c) SELEX Inventions. Archemix shall have the sole right but not the obligation to file, prosecute and maintain Patents on SELEX Inventions at its own expense. 
  
 (d) Archemix Patents. Archemix shall have the
sole right but not the obligation to file, prosecute and maintain Archemix Patents at its own expense. If Archemix elects not to file, prosecute or maintain any ARC 183 Patents in any country, then Archemix shall notify Nuvelo of such election
promptly in writing, but in any event at least 45 days before the next required filing deadline, in order to maintain the availability of Patent protection for the invention(s) claimed in the applicable ARC 183 Patents in the Field. If after
receiving any such notice, Nuvelo notifies Archemix in writing that it wishes to take responsibility for the ARC 183 Patents in such country, then Archemix shall: (i) promptly provide Nuvelo with all pertinent files, correspondence, records,
information and other documents relating thereto in its possession or control; and (ii) take all other actions reasonably necessary to transfer to Nuvelo (or its designee) the right, power and authority to file, prosecute and maintain such ARC 183
Patents in such country. If Nuvelo assumes the filing, prosecution and maintenance of any ARC 183 Patents in any country pursuant to this Section 10.3(d), the Parties shall share equally all expenses incurred in connection with such activities.
Archemix shall assist Nuvelo in connection with the prosecution and maintenance of the applicable ARC 183 Patents. Archemix shall be responsible for assisting Nuvelo in such activities as may be necessary to comply with the terms of the Gilead
Agreement. If, after receiving notice from Archemix under this Section 10.3(d), Nuvelo decides not to file, prosecute or maintain any ARC 183 Patents, Nuvelo will notify Archemix thereof promptly in writing and Archemix shall take such actions as
are necessary to comply with the terms of the Gilead Agreement, the URC Agreement and the ULEHI Agreement, as applicable. If, after receiving notice from Archemix under this Section 10.3(d), Nuvelo assumes the filing, prosecution and maintenance of
any ARC 183 Patents in any country pursuant to this Section 10.3(d) and then later decides not to file, prosecute or maintain any such ARC 183 Patents, then Nuvelo shall: (i) notify Archemix of such election promptly in writing, but in any event at
least 45 days before the next required filing deadline, in order to maintain the availability of Patent protection for the invention(s) claimed in the applicable ARC 183 Patents in the Field; (ii) promptly provide Archemix with all pertinent files,
correspondence, records, information and other documents relating thereto in its possession or control; and (iii) take all other actions reasonably necessary to transfer to Archemix (or its designee) the right, power and authority to file, prosecute
and maintain such ARC 183 Patents in such country 
  
 (e) Nuvelo Patents. Nuvelo shall have the sole right but not the obligation to file, prosecute and maintain Nuvelo Patents at its own expense. 
  

 34. 

 (f) Patent Costs and Budget. All costs incurred during the Collaboration in
relation to the filing, prosecution and maintenance of patent applications and Patents claiming Joint Inventions, and Collaboration Patents specifically claiming the composition of matter, method of making or method of using any Collaboration
Compound or Collaboration Product, shall be referred to herein as “Patent Costs”. The Patent Costs incurred during any calendar year shall not exceed an annual budget determined by the JSC. 
  
 10.4 Enforcement of Patent Rights. 
  
 (a) Notice. If a Third Party is apparently
infringing a Patent under the Archemix Patents or the Nuvelo Patents, the Party first obtaining knowledge of such a claim shall immediately provide the other Party notice of such claim and the related facts in reasonable detail. 
  
 (b) Enforcement During Collaboration. 

  
 (i) Sole Inventions. Each Party
shall have the right, but not the obligation, to enforce any Patent that claims a Sole Invention owned by it in accordance with the terms of this Agreement against an act of infringement and to settle any action brought relating to such
infringement, at its cost and expense. Such Party may grant a license to a Patent claiming a Sole Invention in conjunction with such a settlement, except that no license shall be granted with respect to the manufacture, use or sale of any
Collaboration Compound or any Collaboration Product without the consent of the other Party. If a Party entitled to do so elects not to enforce any Patent in any country that claims a Sole Invention, then that Party shall notify the other Party of
the election promptly in writing. If the alleged infringement of the Third Party is or may reasonably be competing with the interests of the Collaboration, then after receiving notice thereof, the other Party may elect to enforce any Patent claiming
a Sole Invention against the Third Party, in which case the other Party may join the first Party as a co-plaintiff, if necessary. All costs incurred in association with any enforcement action where the alleged infringement of the Third Party is or
may reasonably be competing with the interests of the Collaboration, shall be considered Research Costs, Development Costs or Allowable Commercialization Expenses, as the case may be, but regardless of designation shall be shared equally by the
Parties. All proceeds associated with the enforcement of an action where the alleged infringement of the Third Party is or may reasonably be competing with the interests of the Collaboration, shall also be shared equally by the Parties. For any
other action, all costs and proceeds of the action shall be borne solely by the Party brining the action. 
  
 (ii) Joint Inventions. With respect to the suspected infringement of a Patent that claims a Joint Invention, the JSC shall
determine how to best control the enforcement of such infringement. If either Party brings an action or proceeding in accordance with this Section 10.4(b)(ii), the other Party agrees to be joined as a Party plaintiff and to give the first Party
reasonable assistance and authority to control, file and prosecute the suit as necessary. All costs, liabilities and proceeds associated with the enforcement of a given claim pursuant to this Section 10.4(b)(ii) with respect to a Collaboration
Compound or Collaboration Product shall be shared equally by the Parties. No settlement or consent judgment or other voluntary final disposition of a suit regarding a jointly-owned Patent may be entered into without the joint written consent of
Nuvelo and Archemix. 
  

 35. 

 (iii) Archemix Patents. Archemix shall have the right, but not the
obligation, to enforce any Archemix Patent directly related to or otherwise having claims covering ARC 183, including, but not limited to, method of discovery, composition of matter, use or method of manufacture or ARC 183. Should Archemix elect not
to exercise its right to enforce such an Archemix Patent in the Field, Nuvelo shall then be entitled to enforce the applicable Archemix Patent in the Field with the written consent of Archemix, except that Archemix’s consent shall not be
necessary for Nuvelo to enforce the ARC 183 Patents. No settlement or consent judgment or other voluntary final disposition of a suit brought by Nuvelo regarding an Archemix Patent may be entered into without the written consent of Archemix.
Archemix shall notify Nuvelo of its intention to either exercise or decline the rights afforded to it under this Section 10.4(b)(iii) by written notice no later than 60 days after receiving notice of any claim of potential infringement. All costs,
liabilities and proceeds associated with the enforcement, defense or settlement of a given claim pursuant to this Section 10.4(b)(iii) shall be shared equally by the Parties. 
  
 (iv) If both Nuvelo and Archemix fail to exercise their rights to bring an action or proceeding to so
enforce an Archemix Patent in the Field within a period of one hundred twenty (120) days after receipt of written notice of infringement of such Archemix Patent, then Gilead shall have the right to bring and control any such action by counsel of its
own choice and at its own expense. In such an event, Gilead shall have the right to extend the right to participate in and control, as applicable, any such action to its Affiliates and sublicensees, as Gilead in its sole discretion deems necessary
to satisfy its obligations to its Affiliates and sublicensees. If any such action or proceeding is brought by an Interested Party hereunder, the other Interested Parties agree to be joined as necessary as party plaintiffs and to give the
Interested Party bringing suit reasonable assistance and authority to control, file and prosecute the suit as necessary, at the sole expense of the Interested Party bringing suit. The costs and expenses of the Interested Party bringing suit under
this Section 10.4(b)(iv) (including the internal costs and expenses specifically attributable to such suit) shall be reimbursed first out of any damages or other monetary awards recovered in favor of the Interested Parties, and any remaining damages
shall be paid to the Interested Party that controlled such action. No settlement or consent judgment or other voluntary final disposition of a suit under this Section 10.4(b)(iv) relating to an Archemix Patent brought by an Interested Party may be
entered into without the consent of the other Interested Parties. 
  
 (v) SELEX Inventions. Archemix shall have the sole right but not the obligation to enforce Patents on SELEX Inventions. 
  
 (vi) Nuvelo Patents. Nuvelo shall have the sole right but not the obligation to enforce Nuvelo
Patents. 
  
 (c) Subordination. For
clarity, the Parties agree that the rights of each Party to enforce claims of infringement with respect to a Collaboration Compound or Collaboration Product may be made subordinate to a subsequent Partnering Agreement if such Collaboration Compound
or Collaboration Product is commercialized by Partnered Commercialization. 
  

 36. 

 10.5 Defense of Third Party Claims.  
  
 (a) If a Third Party asserts that a Patent or other
right owned by it is infringed or misappropriated by the manufacture, import, use, sale or offer for sale of any Collaboration Compound or Collaboration Product, the Party first obtaining knowledge of such a claim shall immediately provide the other
Party and Gilead with notice of such claim and the related facts in reasonable detail. The JSC shall determine how to best control the defense of any such claim and the Parties shall enter into a subsequent agreement governing such defense. If the
Parties are conducting the defense in a manner specified by the JSC or provided for in a joint agreement entered into at the time, then all costs, liabilities and proceeds associated with the defense of a given claim with respect to a Development
Compound or Product shall be shared equally by the Parties, but neither Party shall enter into a settlement agreement with such Third Party without the written consent of the other Party. 
  
 (b) If the JSC does not agree on how to control the
defense of any such claim, then each Party shall have the right to defend itself with respect to such claims. In this case, each Party shall bear all costs incurred by it in association with such defense. Any final settlement or damage awards that
shall be paid to such Third Party shall be borne equally by the Parties. 
  
 (c) Notwithstanding anything to the contrary above, the following shall apply. The Interested Parties shall have the right, at their sole discretion, to participate in any action under this Section 10.5 and to
be represented by counsel of their own choice and at their own expense. The Party or Parties designated by the JSC shall control the process to resolve any such assertion of infringement. The matter shall be deemed resolved if the controlling Party
or Parties obtain: (i) a license permitting the manufacture, use, import, offer for sale and sale of the Collaboration Compound or Collaboration Product on a royalty-free basis (ii) a legally binding statement or representation from the Third Party
that: (A) no action will be taken against the Interested Party or Parties, their Affiliates or their sublicensees, or (B) that the patent or other right is not infringed by the Collaboration Compound or Collaboration Product; or (iii) a final
judgment by a court of competent jurisdiction from which no appeal has or can be taken that the Third Party’s patent(s) alleged to be infringed is invalid, or the Third Party’s patent(s) or other right(s) are unenforceable or not infringed
by the Collaboration Compound or Collaboration Product. If the matter is not resolved and an infringement action is filed, the Party or Parties designated by the JSC shall have the primary right to defend any such claim. The Interested Parties shall
have the right, but not the obligation, to participate in any such suit at their sole option and at their own expense. Each Interested Party shall reasonably cooperate with the Interested Parties conducting the defense of the claim. No settlement or
consent judgment or other voluntary final disposition of a suit under this Section 10.5(c) relating to a Collaboration Compound or Collaboration Product brought by an Interested Party may be entered into without the consent of the other Interested
Parties. 
  

	11.	CONFIDENTIALITY 

  
 11.1 Nondisclosure of Confidential Information. All Information disclosed by one Party to the other Party pursuant to this Agreement that it
is marked or otherwise identified as “confidential” or “proprietary” shall be “Confidential Information” of the disclosing Party. Confidential Information also includes all Information developed by either Party
in carrying out 

  

 37. 

 
this Agreement and disclosed to the other Party, or disclosed by either Party under the pre-existing confidentiality and non-use agreement between the
Parties, which agreement shall be superceded by the signing of this Agreement. The Parties agree that during the Term, and for a period of five (5) years thereafter, a Party receiving Confidential Information of the other Party will: (i) maintain in
confidence such Confidential Information to the same extent such Party maintains its own proprietary industrial information of similar kind and value; (ii) not disclose such Confidential Information to any Third Party without prior written consent
of the disclosing Party, except for disclosures made to any Third Party pursuant to arrangements approved by the JSC under confidentiality obligations at least as protective as contained herein; and (iii) not use such Confidential Information for
any purpose except those permitted by this Agreement. 
  
 11.2
Exceptions. The obligations in Section 11.1 shall not apply to Information that the receiving Party can show by competent written proof: 
  
 (a) Is publicly disclosed by the disclosing Party, either before or after the Confidential Information is disclosed to the
receiving Party hereunder; 
  
 (b) Was
known to the receiving Party, without obligation to keep it confidential, before disclosure of the Confidential Information by the disclosing Party; 
  
 (c) Is subsequently disclosed to the receiving Party by a Third Party lawfully in possession thereof and without obligation to keep
it confidential; 
  
 (d) Has been
published by a Third Party; or 
  
 (e) Has
been independently developed by the receiving Party without the aid, application or use of the Confidential Information. 
  
 11.3 Authorized Disclosure. 
  
 (a) A Party may disclose the Confidential Information belonging to the other Party to the extent such disclosure is reasonably
necessary in the following instances: 
  
 (i)
Filing or prosecuting Patents; 
  
 (ii)
Regulatory Filings; 
  
 (iii)
Prosecuting or defending litigation; 
  
 (iv) Complying with applicable governmental regulations; and 
  
 (v) Disclosure, in connection with the performance of this Agreement, to Affiliates and actual or prospective licensees, sublicensees, contractors, research collaborators, employees, consultants, or agents,
each of whom before disclosure must be bound by similar obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 11. The Lead Marketing Party and its sublicensees may also disclose publicly clinical
data for use in connection with the marketing of Collaboration Products in accordance with the customary practice of the pharmaceutical industry. 
  

 38. 

 (b) The Parties acknowledge that the terms of this Agreement shall be treated as
Confidential Information of both Parties. Such terms may be disclosed by a Party, pursuant to a binding contractual obligation similar to, but in no event more lenient than, the terms of confidentiality contained herein, to investment bankers,
investors, and potential investors, lenders and potential lenders and other sources and other potential sources of financing, licensees and potential licensees, acquirer or merger partners and potential acquirer or merger partners and Gilead
Sciences, Inc. and University License Equity Holdings, Inc.. In addition, a copy of this Agreement may be filed by either Party with the Securities and Exchange Commission if such filing is required by law or regulation. In connection with any such
filing, such Party shall endeavor to obtain confidential treatment of economic and trade secret information, and shall provide the other Party with the proposed confidential treatment request with reasonable time for such other Party to provide
comments, which comments shall be reasonably considered by the filing Party. 
  
 11.4 Publicity. The Parties agree that the public announcement of the execution of this Agreement shall be made pursuant to a press release approved by the Parties. Any other publication, news release or
other public announcement relating to this Agreement or to the performance hereunder, shall also be reviewed and approved by both Parties; provided, however, that any disclosure which is required by law as advised by the disclosing Party’s
counsel may be made without the prior consent of the other Party, although the other Party shall be given prompt notice of any such legally required disclosure and to the extent practicable shall provide the other Party an opportunity to comment on
the proposed disclosure. 
  
 11.5 Publications.
During the term of the Collaboration, neither Party shall publish or present the results of studies carried out under this Agreement without the opportunity for prior review by the other Party. Subject to Section 11.3, each Party agrees to provide
the other Party the opportunity to review any proposed abstracts, manuscripts or presentations (including verbal presentations) which relate to any Collaboration Compound or Collaboration Product at least 30 days before its intended submission for
publication and agrees, upon request, not to submit any such abstract or manuscript for publication until the other Party is given a reasonable period of time to secure patent protection for any material in such publication which it believes to be
patentable. Both Parties understand that a reasonable commercial strategy may require delay of publication of information or filing of patent applications. The Parties agree to review and consider delay of publication and filing of patent
applications under certain circumstances. The JSC will review such requests and recommend subsequent action. Neither Party shall have the right to publish or present Confidential Information of the other Party, which is subject to Section 11.1,
without the other Party’s written consent. Nothing contained in this Section 11.5 shall prohibit the inclusion of information necessary for a patent application, so long as the nonfiling Party is given a reasonable opportunity to review and
comment on the information to be included before submission of such patent application. Any disputes between the Parties regarding delaying a publication or presentation or advertising or promotional materials used during commercialization in order
to permit the filing of a patent application shall be referred to the JSC. Following termination of the Collaboration, a Party that continues to develop or commercialize a Product as an Archemix Product or Nuvelo Product, as the case may be, may
publish results of studies of such Product without prior consultation with the other Party. 
  

 39. 

 12. TERM. Subject to Article 13, the term during which this Agreement is in effect (the
“Term”) commences on the Effective Date and expires at such time as neither Party has any outstanding obligations under this Agreement.  
  

	13.	TERMINATION OF COLLABORATION. 

  
 13.1 Collaboration Termination.  
  
 (a) Termination for Material Breach. Either Party may terminate the Collaboration, and also
this Agreement, if the other Party has materially breached or defaulted in the performance of its obligations under this Agreement or failed to use Diligent Efforts in the performance of its obligations under this Agreement, and the non-breaching
Party has provided written notice to the other Party specifying the basis for the termination. For a failure to make a payment set forth in Article 8, the allegedly breaching Party shall have 10 days to cure such breach. For all breaches other than
a failure to make a payment set forth in Article 8, the allegedly breaching Party shall have 60 days to either cure such breach or, if cure cannot be reasonably effected within such 60 day period, to deliver to the other Party a plan for curing such
breach that is reasonably sufficient to effect a cure within the next 30 days. If the breaching Party does not cure the breach before the expiration of 90 days after receipt of the written notice specifying the basis for termination, the Agreement
shall terminate upon the expiration of the 90 day period. If the Parties cannot agree as to whether a breach exists, the dispute shall be resolved pursuant to Article 16, and no termination shall be effective until the matter is so resolved.

  
 (b) Voluntary Termination Other
Than for Material Breach. For reasons other than the other Party’s material breach of its obligations under this Agreement, either Party may terminate the Collaboration on a Product by Product basis, or terminate the Agreement, in its
discretion upon 60 days’ prior written notice to the other Party. 
  
 13.2 Effect of Collaboration Termination. 
  
 (a) Development of Products. 
  
 (i) Nuvelo Product. If the Collaboration is terminated by Nuvelo for Archemix’s material breach under this Agreement pursuant to Section 13.1(a), or by Archemix pursuant to Section 13.1(b)
(voluntary termination), upon the effective date of such termination, any Collaboration Product then under Development or being Commercialized shall cease to be a Collaboration Product and will automatically become a “Nuvelo

 (c)
Royalties and Payments on Nuvelo Products and Archemix Products. 
  
 (i) Royalty Rate and Payments When Termination Before Phase 2 Milestone Achieved. If the Collaboration is terminated before the achievement of the Phase 2 Milestone, then: 
  
 (1) with respect to any Nuvelo Product, Nuvelo shall
have no royalty obligations to Archemix but shall be solely responsible for the Third Party Royalty and any royalties or other ongoing financial obligations resulting from the Parties’ licensing or obtaining rights from Third Parties during the
Term that are necessary to develop, make, have made, use, sell or offer for sale or import a Nuvelo Product; and

 42. 

 (iii) Royalty Adjustment. The royalty amounts set forth above shall be
reduced by 50% on a country-by-country basis at any such time that there is no Patent in effect that is owned or Controlled by the royalty-paying Party or its sublicensee or licensed to it by a royalty receiving Party covering the manufacture, use
or sale of such Product in such country. No royalties shall be payable under Section this 13.2(c)(iii) in any country for any particular Collaboration Product after the 12th anniversary of the first commercial sale of such Collaboration Product in that country.  
  
 (iv) Royalty Report and Payment. Commencing with the first commercial sale of a Nuvelo Product
by Nuvelo or its licensees or sublicensees, or an Archemix Product by Archemix or its sublicensees, the Party or its licensees or sublicensees making such sales shall make quarterly written reports to the other Party within 60 days after the end of
each calendar quarter (the “Royalty Period”), stating in each such report, by Products and by country, the number, description and aggregate Net Sales in U.S. dollars of such Products sold during such Royalty Period by such Party
and its licensees or sublicensees, respectively. The report shall also show: (1) the calculation of Net Sales made by such Party and the royalty payments due to the other Party on such Net Sales for such royalty period; (2) the calculation of Net
Sales made by such Party’s licensees or sublicensees, the amount of sublicense revenue and royalty received from such licensees or sublicensees and the royalty payments due to the other Party on such sublicensee Net Sales for such royalty
period; (3) the amount of taxes, if any, withheld to comply with applicable law; and (4) the exchange rates used in calculating the payments due to the other Party, which exchange rates shall comply with Section 13.2(c)(vi) below. Simultaneously
with the delivery of each such report, the Party making such sales shall pay to the other Party the total royalties, if any, due to the other Party for such Royalty Period. If no royalties are due, the Party making such sales shall so report.

  
 (v) Blocked Currency. In each
country where the local currency is blocked and cannot be removed from the country, royalties arising from sales made in that country shall be paid to the receiving Party in the country in local currency by deposit in a local bank designated by the
receiving Party, unless the Parties otherwise agree. 
  
 (vi) Foreign Exchange. Conversion of sales recorded in local currencies to U.S. dollars will be performed using an exchange rate for conversion of the foreign currency into U.S. dollars, quoted for current transactions for
buying U.S. dollars, as reported in The Wall Street Journal for the last business day of the week before such payment is due. 
  
 (vii) Phase 2 Milestone. If Archemix terminates the Collaboration pursuant to Section 13.1(b) or Nuvelo terminates the
Collaboration pursuant to Section 13.1(a) before the achievement of the Phase 2 Milestone, then Nuvelo’s obligation to pay the Phase 2 Milestone payment shall survive the termination of the Collaboration. 
  
 (d) Manufacturing. If the Collaboration is
terminated by either Party pursuant to Section 13.1(b) (voluntary termination) or by Nuvelo pursuant to Section 13.1(a), the Party that does not have a license under Section 13.2(b) upon such termination (the “Removed Party”) shall,
or shall make the Third Party manufacturer, as necessary, immediately provide to the other Party (the “Continuing Party”) all process and manufacturing technology, material and data and either transfer or provide access to
regulatory filings sufficient to enable the 

  

 43. 

 
Continuing Party or its Third Party designee to produce and supply the Continuing Party’s requirements of Collaboration Compound or Collaboration
Product. The Removed Party shall cooperate with the Continuing Party with respect to such transfer so as to permit the Continuing Party to begin manufacturing and supplying its own requirements as soon as possible, including without limitation
assigning any Third Party manufacturing agreement to the Continuing Party and providing technical advice (including reasonable advice provided at the site of the new manufacturer). If the termination of the Collaboration by the Removed Party is
voluntary, the Continuing Party shall reimburse the Removed Party for any reasonable out-of-pocket costs incurred in connection with the transfer of the manufacturing, and shall pay the Removed Party at the FTE Reimbursement Rate (or other mutually
agreed rate) for any technical advice. In addition, the Removed Party shall provide, or take such action as necessary to make the then current Third Party manufacturer provide, a right of reference and access to the Continuing Party to all of the
Removed Party’s or the Third Party manufacturer’s appropriate regulatory filings for the manufacture of such Collaboration Product. 
  
 (e) Expenses. If the Collaboration is terminated pursuant to Section 13.1, each Party shall submit to the other Party a
final accounting of all Research Costs, Development Costs and Allowable Commercialization Expenses incurred by the reporting Party before the termination occurs, including reasonable detail demonstrating the specific basis for the costs and expenses
included in the summary. Such accounting shall also include any Research Costs, Development Costs and Allowable Commercialization Expenses accrued before the termination occurs but not yet incurred. The Parties shall account for and reimburse all
allowable accrued and incurred Research Costs and Development Costs consistent with the terms set forth in Section 4.9. The Parties shall account for all accrued and incurred Allowable Commercialization Expenses consistent with the computation of
Product Profit and Loss. 
  
 (f)
Transition Period. In an event either Party terminates the Collaboration pursuant to Section 13.1(b) and the other Party desires to carry on the Development and Commercialization of any Product involved in such termination, the
terminating Party shall remain obligated to its responsibilities under the Development Plan and Budget, and the Commercialization Plan and Budget, at the cost of the continuing Party, until it transitions to the continuing Party such
responsibilities, but in any event such period shall last no longer than ninety (90) days. Promptly following the termination, the Parties shall agree upon and implement a plan for effecting such transition. 
  
 (g) Other Effect of Termination; Completion of
Clinical Trials. In any event, termination of the Collaboration shall not relieve the Parties of any liability which accrued hereunder before the effective date of such termination nor preclude either Party from pursuing all rights and remedies
it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation. If a Party terminates the Collaboration voluntarily or breaches this Agreement
at a time when a clinical trial of a Collaboration Product is ongoing, such Party shall remain responsible for one-half of the Development Costs directly attributable to such clinical trial(s) until their completion. 
  
 13.3 Survival. In the event of expiration or termination of
this Agreement, the following provisions of this Agreement shall survive for the period of time set forth in the applicable Section or Article, or if no period is specified, in perpetuity or the maximum amount 

  

 44. 

 
of time permitted under applicable law: Sections 5.15, 7.5, 7.6(b), 13.2, 13.3, 14.6, 14.7, 15.1. 15.2, 15.4, and Articles 1, 9, 10, 11, 16 and 17.

 15.1 Indemnification. 
  
 (a) Subject to Section 15.2, each Party hereby agrees
to defend and hold harmless the other Party and its directors, officers, agents and employees (the “Indemnitees”) from and against any and all damages, liabilities, expenses or loss, including reasonable legal expenses and
reasonable attorneys’ fees (“Losses”) resulting from suits, claims, proceedings or causes of action brought by a Third Party against such Indemnitee: (i) based on breach by the indemnifying Party of a representation or warranty
contained in this Agreement; (ii) based on breach of this Agreement or applicable law by the indemnifying Party; (iii) based on possession, research, Development, manufacture, use, offer for sale, sale or other Commercialization, distribution,
administration, storage or transport of any Aptamer, Collaboration Compound or Collaboration Product by the indemnifying Party, except to the extent also based upon a conflict for which the other Party is responsible under subsection (iv) below;
(iv) resulting from or arising out of a conflict between the indemnifying Party’s execution, delivery or performance of this Agreement, specifically including, without limitation, any conflict resulting or arising out of any rights or licenses
granted by the indemnifying party under this Agreement, and the terms of any other agreement to which the indemnifying Party is or becomes a Party or by which the indemnifying Party is or becomes bound; or (v) based on the negligence or willful
misconduct of the indemnifying Party in the performance of this Agreement; except to the extent such Losses result from (1) breach by the non-indemnifying Party or its Indemnitees of a representation or warranty contained in this Agreement; (2)
breach of this Agreement or applicable law by the 

  

 47. 

 
non-indemnifying Party or its Indemnitees; or (3) the negligence or willful misconduct of the non-indemnifying Party or its Indemnitees in the performance of

EITHER PARTY, ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS OR AFFILIATES BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE,
STRICT LIABILITY OR OTHER TORT, OR OTHERWISE, ARISING OUT OF THIS AGREEMENT. 
  
 15.3 Product Liability. Any Losses arising from a Third Party product liability suit, claim or proceedings with respect to a Product, to the extent the occurrence resulting in such suit takes place

	16.	DISPUTE RESOLUTION. 

  
 16.1 Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the term of this Agreement that
relate to either Party’s rights 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 16 if and when a dispute arises under this Agreement. For all disputes arising under this Agreement, the JSC shall serve as the
initial forum for resolving all such disputes. If the JSC cannot reach an agreement pursuant to Section 2.4 regarding the Development of a Collaboration Compound, including without limitation agreement on the Development Plan and Budget, process,
timeline, deliverables and responsible party designation, such dispute shall be deemed a “Process Dispute.” If the JSC cannot reach a decision regarding the Research of Backup Compounds or Collaboration Compounds pursuant to Section
2.4, then the parties shall discontinue such Research activities in question immediately and no dispute resolution procedures specified in this Article 16 shall be involved. Any dispute arising under this Agreement—other than a Process Dispute,
a dispute described in the preceding sentence or a dispute addressed by Section 16.14—including in particular any dispute regarding the rights and 

  

 48. 

 
obligations of the Parties or any alleged breach of this Agreement, shall be referred to as a “Contract Dispute.” Either Party may formally
request resolution of a Process Dispute or Contract Dispute by providing written notice to the other Party. If the JSC is unable to resolve a Process Dispute or Contract Dispute within 30 days after a Party formally designates a matter as a dispute,
then either Party may, by written notice to the other, have such dispute referred to Chief Executive Officers of the Parties for attempted resolution by good faith negotiations within 30 days for Process Disputes and 30 days for Contract Disputes.
In the event the Chief Executive Officers are not able to resolve the Contract Dispute or Process Dispute within such period, either Party may then invoke the provisions of Sections 16.2 through 16.13 for a Contract Dispute or Section 16.15 for a
Process Dispute. 
  
 16.2 Arbitration for Contract
Disputes. Any Contract Dispute not resolved pursuant to Section 16.1 may be submitted by either Party for final and binding arbitration in accordance with the terms of this Agreement by JAMS. The arbitration will be conducted in New York, New
York under the rules then in effect for JAMS, except as provided herein, 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 such rules of JAMS. 
  
 16.3 Arbitrator for Contract Disputes. 
  
 (a) Subject to Section 16.3(b), the arbitrator shall be 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 30 days, the arbitrator shall be appointed by JAMS within the subsequent 30 days. 
  
 (b) Upon the written request of either Party before
the commencement of the arbitrator’s duties pursuant to this Article 16, there shall be 3 arbitrators rather than 1. If such request is made before the selection of an arbitrator pursuant to Section 16.3(a), then within 30 days after such
request each Party shall select 1 neutral, independent and impartial arbitrator from the pool of retired federal judges presented to the Parties by JAMS and within 30 days thereafter those 2 arbitrators shall select the 3rd arbitrator from such pool. If such request is made after the selection of an arbitrator pursuant to Section 16.3(a), then
within 30 days after such request each Party shall select 1 additional arbitrator from the pool from which the first arbitrator was selected. 
  
 16.4 Governing Law for Contract Disputes. Resolution of all Contract Disputes and any remedies relating thereto, shall be governed by and
construed under the substantive laws of the State of New York, without regard to conflicts of law rules that would provide for application of the law of a jurisdiction outside New York. 
  
 16.5 Rules of Procedure for Contract Disputes. The Parties shall be entitled to discovery as provided in the
Federal Rules of Civil Procedure and the local rules of the Federal District Court in the Southern District of New York, provided, however, that all discovery shall be conducted expeditiously within the time limit set by the arbitrators selected
pursuant to Section 16.3. At the hearing, the Parties may present testimony (either by live witness or 

  

 49. 

 
deposition) and documentary evidence. Each Party shall have the right to be represented by counsel. 
  
 16.6 Rules of Evidence for Contract Disputes. The Federal Rules
of Evidence shall apply to any and all matters submitted to final and binding arbitration under this Agreement. 
  
 16.7 Decision for Contract Disputes. 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 but shall fashion such rules and procedures to best approximate Federal rules and procedures except with respect to procedural time limits and delays (which shall be set by
the arbitrator pursuant to Section 16.5). Reasons for the arbitrator’s decisions should be complete and explicit. A full transcript and record of the proceedings as well as written decisions including all determinations of law and fact shall be
provided for the appellate process. 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 12 months following the selection of the arbitrator as provided for in Section 16.3. 
  
 16.8 Award for Contract Disputes. 
  
 (a) The award shall be paid in U.S. dollars free of any tax, deduction or offset; 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. 
  
 (b) 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. 
  
 (c) Each Party agrees to abide by the award rendered
in any arbitration conducted pursuant to this Article 16, and agrees that a judgment of any Federal District Court having jurisdiction may be entered upon the final award and that other courts may award full faith and credit to such judgment in
order to enforce such award. 
  
 (d) The
award shall include interest from the date of any damages incurred for breach of the Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrator. 
  
 (e) With respect to money damages, nothing contained herein shall be construed to permit the
arbitrator(s) or any court or any other forum to award punitive, consequential or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages. The only damages recoverable

  

 50. 

 
under this Agreement are compensatory damages. For purposes of clarity, the foregoing shall not be interpreted to limit or to expand the express rights
specifically granted in this Agreement. 
  
 16.9 Costs
for Contract Disputes. Except as set forth in Section 16.8, 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. 
  
 16.10 Injunctive Relief for Contract Disputes. 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. 
  
 16.11 Confidentiality for Contract Disputes.
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, 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 each 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. 
  
 16.12 Survivability for Contract Disputes. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after
termination of the contract for any reason. 
  
 16.13
Jurisdiction for Contract Disputes. For the purposes of this Article 16, the parties acknowledge their diversity (Nuvelo having its principal place of business in California and Archemix having its principal place of business in
Massachusetts). 
  
 16.14 Patents and Trademarks.
Any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Patent rights covering the manufacture, use, importation, offer for sale or sale of any Product or of any Nuvelo trademarks, Archemix
trademarks, or trademark rights related to any Product shall be submitted to a court of competent jurisdiction in the country in which such Patent or trademark rights were granted or arose. 
  
 16.15 Neutral Determination for Process Dispute. Any Process
Dispute that is not resolved pursuant to Section 16.1 may be submitted by either Party to a mutually agreed independent industry expert with substantial experience regarding the development or commercialization of pharmaceutical products, as the
case may be (the “Neutral”). If the Parties cannot agree on a Neutral within 30 days after the request of either, then each Party shall select an independent industry expert with substantial experience regarding the development or
commercialization of pharmaceutical product, as the case may be, and the two industry experts will, in no less than 10 days, unanimously select a third independent industry expert with substantial experience regarding the development or
commercialization of pharmaceutical 

  

 51. 

 
products, as the case may be, to be the Neutral. The Neutral shall not have any current interest or current or prior involvement with either Party, unless
the Parties agree otherwise. Within 10 days following the identification of the Neutral: (a) the JSC shall submit to the Neutral a mutually agreed statement of the issue in dispute; and (b) each Party shall submit to the Neutral in writing its
proposal for resolution of the dispute, including portions of the Development Plan and Budget. No ex-parte communication with the Neutral shall be allowed without the consent of the other Party. The Neutral may follow such procedures as he or she
desires. If the Neutral determines that one Party’s proposal is consistent with the typical practices of the pharmaceutical industry with respect to the development of a therapeutic product for the disease in question and the other is not, then
the consistent proposal shall become the Development Plan and Budget. If the Neutral determines that the two proposals are both consistent with the typical practices of the pharmaceutical industry, then the Neutral may select whichever proposal he
or she believes is superior, or may design a compromise proposal incorporating elements of each, in the best judgment of the Neutral. The proposal selected by the Neutral, or designed by the Neutral, shall then become the Development Plan and
Budget. The Parties shall equally share the costs associated with the Neutral’s activities under this Section 16.15. The Parties shall direct the Neutral to complete his or her obligations under this Section 16.15 within 45 days after the
Parties’ submissions of their proposals, and each Party shall cooperate to allow such obligations to be completed within such time period. 
  

	17.	MISCELLANEOUS 

  
 17.1 Entire Agreement; Amendment. This Agreement, including the exhibits attached hereto and the expressly referenced provisions of the
other agreements referenced herein, sets forth the complete, final and exclusive agreement between the Parties, and this Agreement sets forth all the covenants, promises, agreements, warranties, representations, conditions and understandings between
the Parties hereto and supersedes and terminates all prior agreements and understandings between the Parties. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between
the Parties other than as are set forth in this Agreement. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

  
 17.2 Bankruptcy. 
  
 (a) All rights and licenses granted under or pursuant
to this Agreement, including amendments hereto, by each Party to the other Party are, for all purposes of Section 365(n) of Title 11 of the U.S. Code (“Title 11”), licenses of rights to intellectual property as defined in Title 11.
Each Party agrees during the term of this Agreement to create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all such intellectual property. If a case is
commenced by or against either Party (the “Bankrupt Party”) under Title 11, then, unless and until this Agreement is rejected as provided in Title 11, the Bankrupt Party (in any capacity, including debtor-in-possession) and its
successors and assigns (including, without limitation, a Title 11 Trustee) shall, at the election of the Bankrupt Party made within 60 days after the commencement of the case (or, if no such election is made, immediately upon the request of the
non-Bankrupt Party) either: (i) perform all of the obligations provided in this Agreement to be 

  

 52. 

 
performed by the Bankrupt Party including, where applicable and without limitation, providing to the non-Bankrupt Party portions of such intellectual
property (including embodiments thereof) held by the Bankrupt Party and such successors and assigns or otherwise available to them; or (ii) provide to the non-Bankrupt Party all such intellectual property (including all embodiments thereof) held by
the Bankrupt Party and such successors and assigns or otherwise available to them. 
  
 (b) If a Title 11 case is commenced by or against the Bankrupt Party and this Agreement is rejected as provided in Title 11 and the
non-Bankrupt Party elects to retain its rights hereunder as provided in Title 11, then the Bankrupt Party (in any capacity, including debtor-in-possession) and its successors and assigns (including, without limitations, a Title 11 Trustee) shall
provide to the non-Bankrupt Party all such intellectual property (including all embodiments thereof) held by the Bankrupt Party and such successors and assigns or otherwise available to them immediately upon the non-Bankrupt Party’s written
request therefore. Whenever the Bankrupt Party or any of its successors or assigns provides to the non-Bankrupt Party any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 17.2, the non-Bankrupt
Party shall have the right to perform the obligations of the Bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party shall release the Bankrupt Party from any
such obligation or liability for failing to perform it. 
  
 (c) All rights, powers and remedies of the non-Bankrupt Party provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in
equity (including, without limitation, Title 11) in the event of the commencement of a Title 11 case by or against the Bankrupt Party. The non-Bankrupt Party, in addition to the rights, power and remedies expressly provided herein, shall be entitled
to exercise all other such rights and powers and resort to all other such remedies as may now or hereafter exist at law or in equity (including, without limitation, under Title 11) in such event. The Parties agree that they intend the foregoing
non-Bankrupt Party rights to extend to the maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including without limitation for purposes of Title 11: (i) the right of access to any intellectual property
(including all embodiments thereof) of the Bankrupt Party or any Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this Agreement, and, in the case of the Third Party, which is necessary for the
development, registration and manufacture of licensed products; and (ii) the right to contract directly with any Third Party described in subsection (i) above to complete the contracted work. Any intellectual property provided pursuant to the
provisions of this Section 17.2 shall be subject to the licenses set forth elsewhere in this Agreement and the payment obligations of this Agreement, which shall be deemed to be royalties for purposes of Title 11. 
  
 17.3 Force Majeure. Both Parties shall be excused from the
performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long
as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including
without limitation, an act of God, voluntary or involuntary compliance with 

  

 53. 

 
any regulation, law or order of any government, war, civil commotion, labor strike or lock-out, epidemic, failure or default of public utilities or common
carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe; provided, however, the payment of invoices due and owing hereunder shall not be delayed by the payer because of a force majeure affecting the
payer, unless such force Majeure specifically precludes the payment process. 
  
 17.4 Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement and shall be deemed to have been sufficiently given for all
purposes if mailed by first class certified or registered mail return receipt requested, postage prepaid, express delivery service providing evidence of receipt or personally delivered. Unless otherwise specified in writing, the mailing addresses of
the Parties shall be as described below.

provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable
one such that the objectives contemplated by the Parties when entering this Agreement may be realized. 
  
 17.13 Ambiguities. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be
deemed to have authored the ambiguous provision. 
  
 17.14

any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure; provided however, that such disclosure may not be made to the extent a lack of disclosure is reasonably necessary to comply
with any applicable federal or state securities laws. For the purposes of the foregoing sentence: (a) the “tax treatment” of a transaction means the purported or claimed federal income tax treatment of the transaction; and (b) the
“tax structure” of a transaction means any fact that may be relevant to understanding the purported or claimed federal income tax treatment of the transaction.
