2.4 Sublicensing.

(a) Subject to this Section 2.4, Bayer will have the right to sublicense any of its rights under Section 2.1 or 2.2, provided that Bayer may grant a sublicense only to Sublicensees who are distributors doing business in one or more Sublicense Countries. Any such sublicense will require the Sublicensee to comply with the obligations of Bayer as contained herein (specifically including, without limitation, obligations under Articles 8 and 10 and Section 17.15), and include an obligation of the Sublicensee to account for and report its sales of Licensed Product to Bayer on the same basis as if such sales were Net Sales by Bayer. Any sublicense will provide for the termination of the sublicense or the conversion to a license directly between the Sublicensee and Nuvelo, at the option of Nuvelo, upon termination of this Agreement pursuant to Article 15. Bayer will forward to Nuvelo a copy of each fully executed sublicense agreement within sixty (60) days of the execution of the agreement.

2.5 Right of First Refusal. If Nuvelo, in its sole discretion, decides to offer to a Third Party an exclusive or co-exclusive license to Commercialize Licensed Product in the United States, it shall offer such a license to Bayer (or, at Bayer’s option, Bayer’s Affiliate) on terms no less favorable to Bayer than those offered to that Third Party, provided that Bayer’s (or its Affiliate’s, as applicable) commercial infrastructure in the United States, including without limitation its United States market coverage, the size and capabilities of its United States Field Force, and its reimbursement expertise are, in Nuvelo’s sole discretion, at least equal to those of the Third Party. If Bayer (or its Affiliate, as applicable) fails to accept such terms within fifteen (15) business days of Nuvelo’s offer, Nuvelo shall be free to offer such a license to the Third Party for a period of nine (9) months thereafter, provided that the terms offered to the Third Party are not, in the reasonable judgment of Nuvelo, less attractive to Nuvelo, taken as a whole, than the terms previously offered to Bayer. The provisions of this Section 2.5 do not apply to any merger, acquisition or other business combination to which Nuvelo may be a party, whether or not such a transaction involves an assignment of Nuvelo’s rights under this Agreement as contemplated by Section 17.5

2.6 Assignment to Bayer.

The Parties agree that they shall establish a formal framework within which they will discuss strategies for the worldwide Development and Commercialization during the Term.

3.2 Joint Steering Committee. The formal framework referred to in Section 3.1 shall be headed by a Joint Steering Committee (the “JSC”), with such subcommittees as the JSC may establish from time to time as it deems appropriate, including, without limitation, standing subcommittees for Development and Commercialization as more fully described in Article 4 and Article 6.

3.3 Membership of JSC. The JSC will be comprised of at least three (3) members representing each Party, all of whom shall have appropriate expertise and seniority to enable them to make decisions on behalf of the Parties with respect to the issues falling within the jurisdiction of the JSC. Either Party, in its sole discretion, may substitute members of the JSC from time to time upon written notice to the other Party, provided, however that, without limiting the generality of the foregoing, a key objective with respect to membership in the JSC shall be preserving continuity. The JSC shall be chaired at each meeting by a representative of the Party hosting that meeting, as described in Section 3.5. One representative of each of Bayer and Nuvelo from the JDC and from the JCC shall take part in all meetings of the JSC.

3.4 Responsibilities of JSC. The JSC shall have responsibility for overseeing and coordinating the global Development and Commercialization of Licensed Product, including the following specific responsibilities:

(a) establishing a global strategy for the Development and Commercialization of Licensed Product, and overseeing the implementation of such strategy worldwide;

(b) reviewing and approving, or as appropriate amending, all plans, programs, proposals and budgets developed by the JDC and JCC, including, without limitation, Global Development Programs and the annual budget for Development Expenses associated with Global Development Programs;

(d) determining whether the Parties should reprioritize their Development activities based on the JSC’s ongoing evaluation of all such potential indications and adjusting any associated Milestone Events and Milestone Payments due hereunder accordingly; and

(e) performing such other functions as are set forth herein or as the Parties may mutually agree in writing.

3.5 Administrative Matters.

(a) The JSC will establish its own procedural rules for its operation, consistent with the terms of this Article 3. The chairperson of the JSC will be responsible for calling regular meetings of the JSC and for leading the meetings. The chairperson of each JSC meeting will alternate between the Parties. Regular meetings of the JSC will be held at least once per calendar quarter either by phone, videoconference or in person. The JSC also shall meet as necessary, either by phone or in person, to timely address all matters it is called upon to resolve by the JDC or the JCC. A JSC member of the Party hosting the JSC meeting will serve as secretary of that meeting. Within ten (10) business days following each meeting, the secretary of the meeting will prepare and distribute to all members of the JSC the written minutes of the meeting. The minutes will provide a reasonably detailed description of the meeting discussions and a list of any actions, decisions or determinations approved by the JSC. The minutes of each

JSC meeting will be approved or disapproved by each member within ten (10) business days of receipt, and revised as necessary, at the next meeting. Final minutes of each meeting will be distributed to the members of the JSC by the chairperson prior to commencement of the next meeting. Each Party shall bear its own costs associated with its participation on the JSC, including all travel and living expenses.

(b) If a Party’s representative is unable to attend a meeting, that Party may designate an alternate representative with decision making authority for that Party to attend the meeting. Any decision made by that attendee will be considered to be a decision made by the absent representative. In addition, each Party may, at its discretion (and with the consent of the other Party), invite additional employees, consultants or scientific advisors to attend any JSC meetings, provided that any individual so invited will not have any voting power at such JSC meetings. A quorum for each JSC meeting will consist of at least two (2) members from each Party.

3.6 Decision Making. The JSC will operate by consensus. The representatives from each Party will have collectively one vote on behalf of that Party. If the members of the JSC cannot reach consensus on any matter that comes before the JSC, then:

For the avoidance of doubt, control of decision-making authority for any matter as provided above will not relieve the Party with control from any of its representations, warranties and/or covenants in this Agreement, nor will it enable that Party to unilaterally modify or amend the terms of this Agreement.

3.7 Dispute Resolution. Notwithstanding the foregoing, if either Party reasonably believes that the final decision of the Party authorized to cast the deciding vote above would prevent or significantly impinge on the other Party’s ability to undertake the Development or Commercialization of a Licensed Product in such other Party’s portion of the Territory, then the other Party shall have the right to refer such decision to the Chief Executive Officer of Nuvelo and the Head of the Pharmaceutical Division of Bayer, and such dispute shall be resolved in accordance with Section 16.1. Until such dispute is resolved, the Parties shall refrain from taking action on the decision; provided that this Section shall not apply to any decision relating to a Clinical Trial required by a Regulatory Authority in a Party’s portion of the Territory, and the affected Party shall be entitled to conduct such Clinical Trial as so required.

[*]	Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities and Exchange Act of 1934, as amended.

also be reimbursed if both Parties approve the excess Development Expenses (either before or after they are incurred). Within thirty (30) days after the end of each calendar quarter, the Parties will send to each other written statements showing Development Expenses incurred by it during that calendar quarter in connection with Global Development Programs. Within fifty (50) days after the end of each calendar quarter, the Party that has incurred less than its pro rata share of Development Expenses for Global Development Programs during that calendar quarter shall reimburse the other Party, so that following any such Development Expense reimbursement Nuvelo will have incurred sixty percent (60%) of such Development Expenses and Bayer will have incurred forty percent (40%) of such Development Expenses during that calendar quarter.

(b) Nuvelo will not be obligated to expend more than [ * ] Dollars ($[ * ]) as its share of Development Expenses for Global Development Programs for Licensed Product in any calendar year during the term of this Agreement (the “Nuvelo Development Cap”). If the JSC approves an annual budget for such Global Development Programs, [ * ] percent ([ * ]%) of which would exceed the Nuvelo Development Cap, or if during the course of any calendar year Nuvelo incurs agreed-upon Development Expenses that exceed the Nuvelo Development Cap, upon Nuvelo’s written request, Bayer will have the right, but not the obligation to advance any such excess amounts. Bayer will have the right to recover any such advances by reducing royalties payable to Nuvelo under Section 8.3 by [ * ] percent ([ * ]%) on annual Net Sales of Licensed Products less than or equal to [ * ] Dollars ($[ * ]) and [ * ] percent ([ * ]%) on annual Net Sales of Licensed Products in excess of [ * * ] Dollars. In addition, all amounts owed to Bayer as a result of any advances made by Bayer under this Section 4.7(b) will become due and payable within [*] ([*]) business days following the earlier of (i) the tenth anniversary of the Effective Date; and (ii) any merger or acquisition of the equity or assets of Nuvelo pursuant to which a single Third Party acquires control of more than fifty percent (50%) of the voting securities of Nuvelo.

(c) Upon reasonable notice, during normal business hours, and no more than once per calendar year, each Party shall have the right to have independent, certified public accountants, which shall be reasonably acceptable to the audited Party, audit the records of the other Party with respect to Development Expenses incurred by the audited Party during the previous three (3) calendar years. The report of such accountant will be limited to a certificate verifying the correctness of such Development Expenses as previously reported by the audited Party, or identifying any discrepancy between actual and reported Development Expenses, along with an explanation of the basis for such a finding. The result of the audit and the audit report shall be subject to Article 12. The results of such audit may be disputed by the audited Party in accordance with Section 16.1. If an audit discloses a discrepancy between actual and reported Development Expenses, within sixty (60) days of the Parties’ receipt of the audit report or, if disputed, within sixty (60) days after resolution of such dispute, the Party who is obligated to reimburse the other Party for any Development Expenses resulting from the discrepancy will do so. The Party requesting the audit shall bear the full cost and expense of the performance of any such audit, unless such audit discloses an overstatement by a Party of its Development Expenses in the audited period by more than five percent (5%), in which case the audited Party will reimburse the auditing Party the full cost of the performance of such audit. Upon the expiration of three (3) years following the end of any calendar year, the calculation of Development Expenses for purposes of this Section 4.7 will be binding upon the Parties.

[*]	Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities and Exchange Act of 1934, as amended.

(d) Each Party will be solely responsible for all Development Expenses incurred in connection with Country Specific Trials required to support Regulatory Approval in a country in such Party’s portion of the Territory and for all Unilateral Activities pursued by such Party. If Bayer desires to use the efficacy data from a Country Specific Trial in the Nuvelo Territory to support an application for Regulatory Approval in a country in the Bayer Territory, Bayer shall bear forty percent (40%) and Nuvelo shall bear sixty percent (60%) of the Development Expenses incurred in conducting such Country Specific Trial (and Bayer shall make reconciling payments as needed to reflect such split, plus [ * ] percent ([ * ]%) of Bayer’s share of such Development Expenses). If Nuvelo desires to use the efficacy data from a Country Specific Trial in the Bayer Territory to support an application for Regulatory Approval in United States, Bayer shall bear forty percent (40%) and Nuvelo shall bear sixty percent (60%) of the Development Expenses incurred in conducting such Country Specific Trial (and Nuvelo shall make reconciling payments as needed to reflect such split, plus [ * ] percent ([ * ]%) of Nuvelo’s share of such Development Expenses). Nothing in this Section 4.7(d) will require either Party to compensate the other Party if it submits to a Regulatory Authority in that Party’s portion of the Territory data from a Country Specific Trial conducted by the other Party solely because the Regulatory Authority or applicable statutes or regulations require it to do so.

4.8 Unilateral Activities.

(a) In the event the JSC cannot agree whether to pursue a Clinical Trial in support of an indication for a Licensed Product (other than an indication for Licensed Product agreed upon by the Parties as of the Effective Date), a Party shall have the right, on written notice to the other Party, to proceed unilaterally with such Clinical Trial solely to support Regulatory Approval or Commercialization of such Licensed Product in such Party’s portion of the Territory (such activities, the “Unilateral Activities”), and the non-pursuing Party shall be deemed to have opted-out (each, an ‘Opt-Out”), with respect to such Unilateral Activities, provided that, subject to Section 4.8(b), (i) the pursuing Party shall be solely responsible for all Development Expense incurred in connection with such Unilateral Activities, and (ii) the non-pursuing Party shall have no further financial obligation to support or otherwise fund any additional efforts in respect of such Unilateral Activities, and no obligation, responsibility, or authority regarding such additional efforts in respect of such Unilateral Activities; provided, however, that if the non-pursuing Party reasonably believes that the pursuing Party’s conduct of such Unilateral Activities would prevent or significantly impinge on such non-pursuing Party’s ability to undertake the Development or Commercialization of Licensed Product for agreed-upon indication(s) in such non-pursuing Party’s portion of the Territory, then the non-pursuing Party shall have the right to refer such decision to the Chief Executive Officer of Nuvelo and the Head of the Pharmaceutical Division of Bayer, and such dispute shall be resolved in accordance with Section 16.1. Until such dispute is resolved, the Parties shall refrain from taking action on the decision; provided that this Section shall not apply to any decision relating to a Clinical Trial required by a Regulatory Authority, and the affected Party shall be entitled to conduct such Clinical Trial as so required.

(b) The non-pursuing Party shall have the right to opt-in (“Opt-In”) with respect to any Unilateral Activities of which such Party Opted-Out at any time in accordance with this Section 4.8(b). Within twenty (20) days after receipt of a written request by the non-pursuing Party, the pursuing Party shall provide to the non-pursuing Party a written statement of

[*]	Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities and Exchange Act of 1934, as amended.

Development Expenses incurred by the pursuing Party in connection with such Unilateral Activities to date. Within thirty (30) days after receipt of such statement (subject to the non-pursuing Party’s audit rights in accordance with Section 4.7(c)), the non-pursuing Party shall have the right to Opt-In with respect to such Unilateral Activities by providing written notice thereof to the pursuing Party (an “Opt-In Notice”), which Opt-In Notice shall be accompanied by a payment equal to (i) [ * ] percent ([ * ]%) of the total amount of the non-pursuing Party’s share of such Development Expenses, as though such costs and expenses were Development Expenses shared in accordance with Section 4.7(a), and (ii) all interest on such amount accrued from the date that such costs would have been reimbursed had the non-pursuing Party not Opted-Out of such Unilateral Activities (calculated in accordance with Section 10.1(d)). From and after the pursuing Party’s receipt of such payment for the non-pursuing Party’s share of such Development Expenses, such Unilateral Activities shall cease to be Unilateral Activities and shall be deemed Global Development Programs Development Expenses, and the Parties shall share all such Development Expenses in accordance with Section 4.7(a).

(d) Late Payments. Any amounts not paid by Bayer when due under this Agreement will be subject to interest from and including the date payment is due through and including the date upon which Bayer has made a wire transfer of immediately available funds

into an account designated by Nuvelo of such payment at a rate equal to the lesser of (i) the sum of three percent (3%) plus the annual prime rate or successive annual prime rates of interest quoted in the Money Rates section of the on-line edition of The Wall Street Journal (at ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇▇.▇▇▇.▇▇▇) calculated daily on the basis of a 365-day year or (ii) the highest rate permitted by applicable law.

Except as may be set forth in any documents filed with the Securities and Exchange Commission, as required to be filed by it under the Securities Act or Exchange Act, as the case may be, it is not aware of any facts or circumstances, individually or in the aggregate, which would reasonably likely have a materially adverse effect on its business or financial condition.

(f) Nuvelo Patent Rights and Nuvelo Know-How. (i) Nuvelo owns or otherwise Controls the Nuvelo Patent Rights and Nuvelo Know-How, and has the right and authority to grant the rights and licenses granted pursuant to the terms and conditions of this Agreement. Nuvelo has not granted any right, license, or interest in, to, or under the Nuvelo Patent Rights or

Nuvelo has not received written notice from any Third Party of any issued and enforceable patent of such Third Party which would be infringed by the Development or Commercialization of Licensed Product in the Territory under this Agreement. Further, to Nuvelo’s Knowledge, the Development and Commercialization of Licensed Product under this Agreement in the Territory does not infringe upon any issued and enforceable patent of any Third Party.

(i) Third Party Agreements. Nuvelo has maintained, is in compliance with, and has received no notice of default under any agreements with Third Parties relating to Licensed Product, including, without limitation, the Amgen-Nuvelo Agreement and the Warrant Purchase Agreement (as defined in the Amgen-Nuvelo Agreement).

13.3 Mutual Covenants. Each Party hereby covenants to the other Party as of the Effective Date as follows:

(a) No Conflict. It will not during the term of this Agreement grant any right, license, consent or privilege to any Third Party(ies) in the Territory which would conflict with the rights granted to the other Party under this Agreement, and will not take any action that would in any way prevent it from assuming its obligations or granting the rights granted to the other Party under this Agreement or that would otherwise materially conflict with or adversely affect its obligations or its assumption of the rights granted to the other Party under this Agreement.

(b) Exclusivity. It will work exclusively with the other Party with respect to the Development and Commercialization of Licensed Product in the Bayer Territory (subject to the Parties’ rights under Article 2 of this Agreement to grant sublicenses to Third Parties and the Parties’ right to engage subcontractors). It will not, directly or indirectly, Commercialize a Competitive Product anywhere in the world during the Term. Each Party will be free to conduct research and development with respect to a Competitive Product, provided as follows: If Nuvelo develops a Competitive Product during the Term, it will either ▇▇▇▇▇ ▇▇▇▇▇ a license to commercialize the Competitive Product in the Bayer Territory, in which case Nuvelo will have the right to commercialize the Competitive Product in the United States on terms to be negotiated and agreed upon by the Parties, or it will license the worldwide, exclusive rights to commercialize the Competitive Product to a Third Party. If Bayer develops a Competitive Product during the Term, it will either grant Nuvelo a license to commercialize the Competitive Product in the United States on terms to be negotiated and agreed upon by the Parties, in which case Bayer will have the right to commercialize the Competitive Product in the Bayer Territory, or it will license the worldwide, exclusive rights to commercialize the Competitive Product to a Third Party.

(c) Regulatory Data. It will store and provide the other Party access to source data supporting all Regulatory Filings and Regulatory Approvals for the longer of (i) ten (10) years from the date of generation of such data, and (ii) the time period required by any applicable Regulatory Authority in the Territory.

(d) No Debarment. In the course of the Development, Commercialization and any permitted manufacture of Licensed Product during the Term, it will not knowingly use and will not have knowingly used any employee or consultant who is or has been debarred by a Regulatory Authority or, to the best of such Party’s knowledge, is or has been the subject of debarment proceedings by a Regulatory Authority.

(e) Compliance. It will comply with all applicable statutes, regulations and guidance of Regulatory Authorities in carrying out its activities regarding the Development, manufacturing and Commercialization of Licensed Product in its portion of the Territory.

(f) Diligence.

(g) Limitation of License Granted. Bayer will not use the Nuvelo Technology or any Nuvelo Material and Manufacturing Information and Nuvelo will not use the Bayer

Technology outside the scope of any licenses so granted. Without limiting the generality of the previous sentence, neither Party will sell any Licensed Product outside of its portion of the Territory and each Party will use reasonable efforts to prevent the unauthorized importation of Licensed Product into the other Party’s portion of the Territory.

(h) No Misappropriation. It will not knowingly misappropriate the trade secret of a Third Party in its activities to Develop, manufacture, or Commercialize Licensed Product.

13.4 Additional Covenants of Nuvelo. Nuvelo acknowledges that Bayer will be substantially damaged as a result of any termination of this Agreement by Amgen, Inc. in the event of termination of the Amgen-Nuvelo Agreement as a result of Nuvelo’s default thereunder. Accordingly, Nuvelo hereby covenants to Bayer:

(a) On an ongoing basis throughout the term of the Amgen-Nuvelo Agreement Nuvelo will keep Bayer apprised of Nuvelo’s performance of its obligations under the Amgen-Nuvelo Agreement and the Warrant Purchase Agreement (as defined in the Amgen-Nuvelo Agreement) including by (i) transmitting to Bayer on a quarterly basis a summary report of Nuvelo’s performance of (or failure to perform) its obligations under the Amgen-Nuvelo Agreement and/or the Warrant Purchase Agreement during the preceding quarter (or, if applicable, a report that no such performance was due during such quarter) and (ii) providing copies to Bayer of all reports and statements required to be delivered by Nuvelo under the Amgen-Nuvelo Agreement as and when Nuvelo transmits the same to Amgen, Inc. All such reports and statements shall be the Confidential Information of Nuvelo and shall be subject to Article 12.

(b) Nuvelo will continue to comply with and perform all of its obligations under the Amgen-Nuvelo Agreement and the Warrant Purchase Agreement. Nuvelo will in good faith consider and act on any concerns reasonably raised by Bayer with respect to Nuvelo’s compliance with the Amgen-Nuvelo Agreement and/or the Warrant Purchase Agreement.

(c) Within five (5) days of receipt of any Notice of Default or any other notice of termination from Amgen, Inc. under the Amgen-Nuvelo Agreement. Nuvelo shall give written notice of the same to Bayer. Bayer shall have the right, but not the obligation, to cure any Nuvelo default in its obligations to Amgen if Bayer in its reasonable judgment believes that Nuvelo’s efforts to cure that default will not be sufficient to avoid termination of the Amgen-Nuvelo Agreement. Nuvelo will provide to Bayer all data, reports and other information reasonably requested by Bayer in connection with Bayer’s effort to cure as provided in the preceding sentence. Bayer may offset any amounts paid by Bayer to Amgen or otherwise expended by Bayer to cure the default, plus an additional [ * ] percent ([ * ]%), against any payments subsequently due to be paid by Bayer to Nuvelo under Section 4.7 or Article 8 of this Agreement.

(d) Within ten (10) days of execution of this Agreement by the Parties, Nuvelo will inform Amgen, Inc. that the Parties have entered into this Agreement and, thereafter, Nuvelo shall use reasonable efforts to negotiate and enter into an amendment of the Amgen-Nuvelo Agreement with Amgen, Inc. whereby Amgen will waive its right under Section 2.3(a) of the Amgen-Nuvelo Agreement to terminate this Agreement and will agree that, in the event of

[*]	Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities and Exchange Act of 1934, as amended.

termination of the Amgen-Nuvelo Agreement pursuant to Article 12 thereof, Nuvelo shall assign this Agreement to Amgen and this Agreement shall remain in full force and effect between Amgen and Bayer.

13.5 Additional Covenants of Bayer. Bayer acknowledges that Nuvelo will be substantially damaged as a result of any termination of the Amgen-Nuvelo Agreement by Amgen, Inc. as a result of Bayer’s default hereunder. Accordingly, Bayer hereby covenants to Nuvelo that if Nuvelo receives any Notice of Default from Amgen, Inc. under the Amgen-Nuvelo Agreement that arises as a result of any breach of this Agreement by Bayer, Nuvelo shall have the right, but not the obligation, to cure any such Bayer breach if Nuvelo in its reasonable judgment believes that Bayer’s efforts to cure that breach will not be sufficient to avoid termination of the Amgen-Nuvelo Agreement. Within thirty (30) days of Nuvelo’s cure of any such breach on Bayer’s behalf, Bayer will pay to Nuvelo any amounts paid by Nuvelo to Amgen or otherwise expended by Nuvelo to cure the default, plus an additional [*] percent ([*]%). For the avoidance of doubt, nothing in Section 13.4 or this Section 13.5 shall require Bayer to make any payments to Amgen under the Amgen-Nuvelo Agreement, and, as provided in Section 8.4, Nuvelo shall be responsible for paying any and all amounts due to Amgen under the Amgen-Nuvelo Agreement.

13.6 Disclaimers. EXCEPT AS EXPRESSLY PROVIDED HEREIN, THE LICENSE GRANTS, MATERIALS AND INFORMATION PROVIDED HEREUNDER ARE BEING PROVIDED “AS IS” AND WITHOUT ANY REPRESENTATIONS OR WARRANTIES. EXCEPT FOR THE EXPRESS WARRANTIES SET FORTH IN THIS ARTICLE 13, NEITHER PARTY MAKES ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OF ANY TYPE WHATSOEVER UNDER THIS AGREEMENT OR REGARDING THE MATERIALS AND INFORMATION. EACH PARTY EXPRESSLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY, OF FITNESS FOR A PARTICULAR PURPOSE OR OF NONINFRINGEMENT.

ARTICLE 14

INDEMNIFICATION

14.1 Indemnification by Nuvelo. Nuvelo hereby agrees to defend, hold harmless and indemnify (collectively “Indemnify” or be “Indemnified”) Bayer and its Affiliates, agents, directors, officers and employees (the “Bayer Indemnitees”) from and against any and all Losses resulting from any Third Party claims, suits, actions or demands arising out of (a) any of Nuvelo’s representations and warranties set forth in this Agreement being untrue in any material respect when made and/or (b) any material breach or material default by Nuvelo of its covenants, agreements or obligations under this Agreement, except to the extent such Losses result from (i) any of Bayer’s representations or warranties set forth in this Agreement being untrue in any material respect when made, or (ii) any material breach or material default by Bayer of its covenants, agreements or obligations under this Agreement. To be eligible to be so Indemnified as described in this Section 14.1, the Bayer Indemnitees will provide Nuvelo with prompt written notice of any claims, suits, actions or demands (with a description of the claim and the nature and amount of any such Loss) giving rise to the indemnification obligation pursuant to this Section 14.1 and the exclusive ability to defend such claims, suits, actions or demands (with the reasonable cooperation of Bayer Indemnitees). Nuvelo will be relieved of its obligations only if any failure by the Bayer Indemnitee to deliver prompt notice will have been prejudicial to its ability to defend such claims, suits, actions or demands. Bayer will have the right to retain its

own counsel, at its own expense. Nuvelo will not settle or consent to the entry of any judgment with respect to any claim for Loss for which indemnification is sought, in a manner that would materially adversely affect Bayer, without Bayer’s prior written consent (not to be unreasonably withheld). Nuvelo’s obligation to Indemnify the Bayer Indemnitees pursuant to this Section 14.1 will not apply to the extent of any Losses (i) that arise from the negligence or intentional misconduct of any Bayer Indemnitee; (ii) that arise from Bayer’s material breach of any representation, warranty, covenant or obligation under this License Agreement; or (iii) for which Bayer is obligated to Indemnify the Nuvelo Indemnitees pursuant to Section 14.2 of this License Agreement.

14.2 Indemnification by Bayer. Bayer hereby agrees to Indemnify Nuvelo and its Affiliates, agents, directors, officers and employees (the “Nuvelo Indemnitees”) from and against any and all Losses arising from Third Party claims, suits, actions or demands resulting directly or indirectly from (a) any of Bayer’s representations and warranties set forth in this Agreement being untrue in any material respect when made and/or (b) any material breach or material default by Bayer of its covenants, agreements or obligations under this Agreement, except to the extent such Losses result from (i) any of Nuvelo’s representations and warranties set forth in this Agreement being untrue in any material respect when made, or (ii) any material breach or material default by Nuvelo of its covenants, agreements or obligations under this Agreement. To be eligible to be Indemnified as described above in this Section 14.2, the Nuvelo Indemnitees will provide Bayer with prompt written notice of any claims, suits, actions or demands (with a description of the claim and the nature and amount of any such Loss) giving rise to the indemnification obligation pursuant to this Section 14.2 and the exclusive ability to defend such claims, suits, actions or demands (with the reasonable cooperation of Nuvelo Indemnitees). Bayer will be relieved of its obligations only if any failure by the Nuvelo Indemnitee to deliver prompt notice will have been prejudicial to its ability to defend such claims, suits, actions or demands. Nuvelo will have the right to retain its own counsel, at its own expense. Bayer will not settle or consent to the entry of any judgment with respect to any claim for Loss for which indemnification is sought, in a manner that would materially adversely affect Nuvelo, without Nuvelo’s prior written consent (not to be unreasonably withheld). Bayer’s obligation to Indemnify the Nuvelo Indemnitees pursuant to this Section 14.2 will not apply to the extent of any Losses (i) that arise from the negligence or intentional misconduct of any Nuvelo Indemnitee (including but not limited to that arising from the manufacture of Licensed Product by Nuvelo), (ii) that arise from any material breach by Nuvelo of any representation, warranty, covenant or obligation under this License Agreement or (iii) for which Nuvelo is obligated to Indemnify the Bayer Indemnitees pursuant to Section 14.1 of this License Agreement.

14.3 Product Liability Claims.

(a) Bayer hereby agrees to Indemnify the Nuvelo Indemnitees from and against any and all Losses arising from Product Liability Claims in the Bayer Territory and Nuvelo hereby agrees to Indemnify the Bayer Indemnitees from and against any and all Losses arising from Product Liability Claims in the Nuvelo Territory, except as follows: Each Party shall be solely responsible for all Product Liability Claims resulting from, and to the extent allocable to, (i) such Party’s or its Affiliate’s material failure to adhere to the terms of any Development or Commercialization plan approved by the JSC, (ii) the distribution by such Party or its Affiliate of

Promotional Materials that fall outside the guidelines established by the JSC, (iii) the making of any claim or representation in respect of the Licensed Product or the respective characteristics thereof by or on behalf of such Party or its Affiliate (by members of its sales force or otherwise) that have not been approved by the JSC or which do not represent an accurate summary or explanation of the labeling of the Licensed Product or a portion thereof or (iv) Non-Conformance of the Licensed Product where, with respect to Bayer, such Non-Conformance occurred after such Licensed Product was delivered to Bayer by Nuvelo and, with respect to Nuvelo, such Non-Conformance existed at the time such Licensed Product was delivered by Nuvelo.

(b) Each Party shall give the other prompt written notice of any Product Liability Claim, but the omission of such notice shall not relieve either Party from its obligations under this Section 14.4, except to the extent the other Party can establish actual prejudice and direct damages as a result thereof. With respect to each Product Liability Claim, Nuvelo shall have the first right to defend and settle such Product Liability Claim. In the event that Nuvelo does not assume the defense of such Product Liability Claim within ninety (90) days following Nuvelo’s receipt of notice of the commencement or assertion of such Product Liability Claim, Bayer shall have the right, but not the obligation, to take the lead role in the defense of such Product Liability Claim. The Party assuming the defense of any Product Liability Claim as permitted under this Section 14.4 (the “Controlling Party”) shall consult with the other Party on all material aspects of the defense and the Parties shall cooperate fully with each other in connection therewith. The non-defending Party shall also have the right to participate in the defense of any Product Liability Claim using attorneys of its choice, at its own expense. In furtherance of the Parties’ cooperation, the Controlling Party will consult with the other Party regarding strategic decisions, including without limitation the retention of counsel and defense of each Product Liability Claim. The Controlling Party will otherwise keep the other Party fully informed of the status and progress of the defense and any settlement discussions concerning the Product Liability Claim. Any settlement of a Product Liability Claim that would admit liability on the part of any Party or its Affiliates, or that would involve any relief other than the payment of money damages within a budget previously agreed to by the Parties, shall be subject to the prior written approval of both Parties, such approval not to be unreasonably withheld or delayed. All damages and expenses (including attorney’s fees) incurred in connection with the defense of a Product Liability Claim shall be allocated between Nuvelo and Bayer in accordance with Section 14.4(a).

14.4 Insurance. During the Term and for a period of five (5) years after the expiration of this Agreement or the earlier termination thereof, each Party shall obtain and/or maintain, respectively, at its sole cost and expense, product liability insurance (including any self-insured arrangements) in amounts, respectively, which are reasonable and customary in the pharmaceutical industry for companies of comparable size and activities at the respective place of business of each Party; provided that Clinical Trial insurance policies will be required only while trials are ongoing. Such product liability insurance or self-insured arrangements shall insure against all liability, including without limitation personal injury, physical injury, or property damage arising out of, for Nuvelo, the manufacture of the Licensed Product, and for each Party, the sale, distribution, or marketing of the Licensed Product in such Party’s portion of the Territory. Such insurance will not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 14. Each Party will provide the other Party with a copy of the certificate of insurance or other evidence of such insurance and/or self-insurance, upon request. Each Party will provide the other Party with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance or self-insurance that materially adversely affects the rights of the other Party hereunder.

14.5 Limitation of Liability. EXCEPT FOR A PARTY’S BREACH OF ITS OBLIGATIONS UNDER ARTICLE 12, NEITHER PARTY NOR ITS RESPECTIVE AFFILIATES, WILL BE LIABLE FOR SPECIAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES, WHETHER IN CONTRACT, WARRANTY, TORT, STRICT LIABILITY OR OTHERWISE INCURRED BY THE OTHER PARTY IN CONNECTION WITH THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO DAMAGES MEASURING LOST PROFITS OR BUSINESS OPPORTUNITIES. THIS SECTION 14.6, WILL NOT BE CONSTRUED TO LIMIT EITHER PARTY’S OBLIGATIONS UNDER SECTIONS 14.1 THROUGH 14.4.

ARTICLE 15

TERM AND TERMINATION

15.1 Term. This Agreement will become effective on the Effective Date and will remain in full force and effect, unless earlier terminated pursuant to this Article 15, on a country-by-country basis until there is no remaining Royalty payment obligation in any country, as set forth in Section 8.5. Upon the expiry of Bayer’s obligation to pay Royalties under this Agreement for Licensed Product in a country, Bayer will have a fully paid-up, royalty-free, license for use of joint inventions and under the Nuvelo Technology and the Nuvelo Material and Manufacturing Information to use, sell, offer to sell, have sold, import, export and otherwise exploit, transfer physical possession of and transfer title or interest in or to Licensed Product in such country, and the purchase and supply commitments of the Parties in such case will terminate except as otherwise provided in the Manufacturing Agreement, if then in effect.

15.2 Remedies for Default.

(a) If any material representation or warranty made hereunder by either Party will have been untrue in any material respect (“Representation Default”), or upon any material breach or material default of an obligation of this Agreement by a Party (“Performance Default”), the Party not in default (“Non-Defaulting Party”) must first give the other Party (“Defaulting Party”) written notice thereof (“Notice of Default”), which notice must state the nature of the Representation Default or Performance Default in reasonable detail and must request the Defaulting Party cure such Representation Default or Performance Default within sixty (60) days. During any such 60-day period after receipt or delivery of a Notice of Default under this Section 15.2(a), all of the Party’s respective rights and obligations under the affected parts of this Agreement, including but not limited to Development, manufacturing and Commercialization, will (to the extent applicable) remain in force and effect. If the Defaulting Party disputes the existence, extent or nature of any default set forth in a Notice of Default or an alleged failure to cure a default, the Parties will use good faith efforts to resolve the dispute as provided in Section 16.1, and if those good faith efforts do not resolve the dispute, Nuvelo will have the rights set forth in Section 15.2(b) in the event of a Representation Default or a Performance Default by Bayer, and Bayer will have the rights set forth in Section 15.2(c) in the event of a Representation Default or a Performance Default by Nuvelo.

(b) Bayer. In the event of a Representation Default or a Performance Default by Bayer that will not have been cured within the 60-day period set forth in Section 15.2(a) above

after receipt of a Notice of Default (or Bayer will not have presented a reasonably achievable plan to cure such Default as promptly as is reasonably practicable under the circumstances), and if efforts to resolve a dispute, if any, under Section 16.1 are unsuccessful, Nuvelo, at its option and on written notice to Bayer, may bring an action against Bayer for damages or equitable relief pursuant to Section 16.2; provided that such action shall be without prejudice to any of its other rights conferred on it by this Agreement and will be in addition to any other remedies available to it by law or in equity.

(c) Nuvelo. In the event of a Representation Default or a Performance Default by Nuvelo that will not have been cured within the 60-day period set forth in Section 15.2(a) after receipt of a Notice of Default (or Nuvelo will not have presented a reasonably achievable plan to cure such Default as promptly as is reasonably practicable under the circumstances), and, if efforts to resolve a dispute, if any under Section 16.1 are unsuccessful, Bayer, at its option and on written notice to Nuvelo, may bring an action against Nuvelo for damages or equitable relief pursuant to Section 16.2; provided that such action shall be without prejudice to any of its other rights conferred on it by this Agreement and will be in addition to any other remedies available to it by law or in equity.

(d) Subject to Section 13.4(d), if Amgen Inc. terminates the Amgen-Nuvelo Agreement due to a material breach of the Amgen-Nuvelo Agreement by Nuvelo, then at Amgen’s discretion Amgen shall have the right to terminate this Agreement or to require assignment of Nuvelo’s rights under this Agreement to Amgen. If Amgen elects to so terminate this Agreement at any time prior to [ * ] years after the First Commercial Sale of a Licensed Product in a Major Country, Canada or Japan, then, within [ * ] of such termination, Nuvelo shall pay to Bayer an amount equal to [ * ] under this Agreement, including without limitation all [ * ] prior to the date of such termination. If Amgen elects to so terminate this Agreement in any of the [ * ] through the [ * ] after the First Commercial Sale of a Licensed Product in a Major Country, Canada or Japan, the foregoing payment obligation shall be reduced by [ * ] percent ([ * ]%) per [ * ] and if Amgen elects to so terminate this Agreement at any time after ten (10) years after the First Commercial Sale of Licensed Product in a Major Country, Canada or Japan, Nuvelo shall have no obligation to pay Bayer under this Section 15.2(d).

(e) Subject to Section 13.5, if Amgen Inc. terminates the Amgen-Nuvelo Agreement due to a breach of this Agreement by Bayer at any time prior to [ * ] years after the First Commercial Sale of Licensed Product in any Major Country, Canada or Japan, then within [ * ] of such termination, Bayer shall pay to Nuvelo all [ * ] as notified by Nuvelo to Bayer in writing, together with all [ * ] as of the effective date of such termination, whether or not such [ * ] are otherwise payable [ * ]. If Amgen elects to so terminate the Amgen-Nuvelo Agreement in any of the [ * ] through the [ * ] after the First Commercial Sale of a Licensed Product in a Major Country, Canada or Japan, the foregoing payment obligation shall be reduced by [ * ] percent ([ * ]%) per year, and if Amgen elects to so terminate the Amgen-Nuvelo Agreement at any time after [ * ] after the First Commercial Sale of Licensed Product in a Major Country, Canada or Japan, Bayer shall have no obligation to pay Nuvelo under this Section 15.2(e).

15.3 Bankruptcy.

(a) Either Party may terminate this Agreement if the other Party (the “Bankrupt Party”) will file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Bankrupt Party or of its assets, or if the Bankrupt Party proposes a written agreement of composition or extension of its debts, or if the Bankrupt Party will be served with an involuntary petition in bankruptcy or seeking reorganization, liquidation, dissolution, winding-up arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or other similar act or law of any jurisdiction now or hereafter in effect, or there will have been issued a warrant of attachment, execution, or similar process against it, filed in any insolvency proceeding, and the petition will not be dismissed within ninety (90) days after the filing thereof, or if the Bankrupt Party will propose or be a party to any dissolution or liquidation, or if the Bankrupt Party will make an assignment for the benefit of creditors.

(b) All rights and licenses granted under or pursuant to this Agreement by Nuvelo or Bayer are and will otherwise be deemed to be for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that each Party will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a bankrupt Party under the U.S. Bankruptcy Code, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property and all embodiments of such intellectual property, and same, if not already in the other Party’s possession, will be promptly delivered to the other Party (i) upon any such commencement of a bankruptcy proceeding, upon the other Party’s written request therefor, unless the non-bankrupt Party (or a trustee on behalf of the non-bankrupt Party) elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of the non-bankrupt Party, upon written request therefor by the other Party.

15.4 Bayer Termination; Effects of Termination. Bayer may at its option, at any time during the Term, terminate this Agreement upon giving Nuvelo twelve (12) months’ written notice. If Nuvelo commits a Performance Default for failure to timely pay any Development Expenses in accordance with Section 4.7 and does not cure such Performance Default within the period set forth in Section 15.2(a) after receipt of a Notice of Default, Bayer may terminate this Agreement upon giving Nuvelo sixty (60) days’ written notice. In addition to any other remedies that may be available at law or equity, upon termination of this Agreement, the rights and obligations of the Parties will be as set forth in this Section 15.4. In addition, if Bayer terminates this Agreement under the first sentence of this Section 15.4, Bayer will continue to reimburse Nuvelo for Bayer’s share of Development Expenses under Section 4.7 incurred in conducting Global Development Programs approved by the JSC prior to the date of Bayer’s notice of termination to Nuvelo.

(a) The following provisions will remain in full force and effect after the expiration or termination of this Agreement: Article 1 (Definitions); Article 10 (Payments, Records, Audit, only with respect to accrued rights and obligations as to payments); Article 11

(Publications); Article 12 (Confidentiality); Section 13.6 (Disclaimers); Article 14 (Indemnification); Article 15 (Term and Termination); Article 16 (Dispute Resolution); and Article 17 (General).

(b) The Parties will retain their respective ownership rights as set forth in Section 9.1. Nuvelo will have the right to file, prosecute, defend and maintain Joint Patent Rights under Section 9.2 and Product Trademarks under Section 9.2, enforce Joint Patent Rights under Section 9.3 and Product Trademarks under Section 9.3 and defend any action claiming the infringement of any Third Party Patent Rights or any Third Party Trademark under Section 9.4 and to publish under Article 11.

(c) Bayer will within thirty (30) days (other than with respect to Nuvelo Material and Manufacturing Information, in which case by no later than completion of its obligations, if any, under Section 15.4(d) below) destroy, or at Nuvelo’s request return, all Nuvelo Confidential Information, Nuvelo Know-How and Nuvelo Material and Manufacturing Information (other than with respect to maintaining one (1) archival copy of Confidential Information related thereto for its legal files, for the sole purpose of determining its obligations hereunder) and will provide Nuvelo with certification by an officer of Bayer that all such materials have been destroyed or returned to Nuvelo. Nuvelo will within thirty (30) days destroy, or at Bayer’s request return, all Bayer Confidential Information and Bayer Know-How (other than with respect to maintaining one (1) archival copy of Confidential Information related thereto for its legal files, for the sole purpose of determining its obligations hereunder) and will provide Bayer with certification by an officer of Nuvelo that all such materials have been destroyed or returned to Bayer.

(d) Bayer will promptly transfer to Nuvelo ownership of all Regulatory Filings and Regulatory Approvals then in Bayer’s name for all Licensed Product and will notify the appropriate Regulatory Authorities and take any other action reasonably necessary to effect such transfer of ownership. Bayer will assign to Nuvelo Bayer’s right, title and interest in the Product Trademarks. Bayer will grant to Nuvelo a paid up, royalty-free, non-exclusive, worldwide license under Bayer’s copyrights in all Promotional Materials. If ownership of a Regulatory Filing or Regulatory Approval in any country cannot be transferred from Bayer to Nuvelo, Bayer will grant to Nuvelo an exclusive right of access and reference to the Regulatory Filing or Regulatory Approval in the country in order to enable Nuvelo to become a sponsor and party of record of an IND. If such right of access and reference is not sufficient to permit Nuvelo to file a Drug Approval Application and receive Regulatory Approval or to Develop, manufacture or Commercialize Licensed Product, Bayer will provide Nuvelo with any and all information necessary for Nuvelo to carry out such activities.

(e) Nuvelo will have the right to use Bayer’s Trademarks in the selling of any existing inventory of Licensed Product(s) and to use Promotional Materials it then has on hand, but only if Nuvelo promptly creates new Promotional Materials (which do not use Bayer’s corporate name and/or logo), with no obligation of accounting to Bayer. The license granted by Bayer to Nuvelo under Section 2.3 will survive termination of this Agreement by Nuvelo under Section 15.2 or Section 15.3, except that the rights conferred thereunder will become worldwide upon such termination.

(f) Bayer will within thirty (30) days (other than with respect to Third Party agreements entered into pursuant to Section 2.4, in which case by no later than completion of its obligations if any under Section 15.4(g) below), at the request of Nuvelo, assign (if assignable under its terms) to Nuvelo all of Bayer’s rights and obligations under any then-existing Third Party licenses having a license grant limited specifically to Licensed Product, regarding the use, selling, offering to sell, and importing, exporting or otherwise transferring physical possession of or otherwise transferring title in or to Licensed Product and will not (until receiving notice of whether or not Nuvelo desires such an assignment) terminate or amend any such Third Party license. Otherwise, Bayer will, at the request of Nuvelo, sublicense (if sublicensable under its terms) to Nuvelo all of Bayer’s rights and obligations under any then-existing Third Party licenses regarding the use, selling, offering to sell, and importing, exporting or otherwise transferring physical possession of or otherwise transferring title in or to Licensed Product and will not (until receiving notice of whether or not Nuvelo desires such a license) terminate or amend any Third Party license. The assignment or sublicense will be made for no additional consideration and be under the same terms and conditions as the underlying agreement.

(g) If Nuvelo becomes entitled to terminate this Agreement at any time after the First Commercial Sale of Licensed Product in the Bayer Territory, Bayer will, in no event in excess of ninety (90) days after Nuvelo’s delivery of notice of termination to Bayer (other than with respect to obligations which explicitly exceed such 90-day period), conduct an orderly transition of rights and responsibilities from Bayer to Nuvelo or to a Third Party, as the case may be. Further, Bayer will cooperate and assist Nuvelo to effect any such transition of rights and responsibilities in an orderly, reasonable and businesslike manner. The assistance will include, but not be limited to (i) making its personnel and other resources reasonably available to Nuvelo, as necessary and (ii) transferring copies of all relevant information, files or data containing Information and all Materials to Nuvelo.

(h) Except as expressly set forth in this Section 15.4, all other rights and obligations under this Agreement will terminate upon termination of this Agreement in accordance with this Article 15.

15.5 Accrued Rights. Termination, relinquishment or expiration of any licenses under this Agreement for any reason in accordance with this Article 15 will be without prejudice to any rights which will have accrued to the benefit of either Party or any liability incurred by either Party prior to the effective date of termination, relinquishment or expiration, and will not 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.

ARTICLE 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 from, concerning or in any way relating to 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.

(a) The Parties will undertake good faith efforts to resolve any dispute in good faith. In the event the Parties will be unable to resolve such dispute, either Party may, by written notice to the other Party, have any dispute between the Parties referred to the Chief Executive Officer of Nuvelo and the Head of the Pharmaceutical Division of Bayer who shall meet for attempted resolution by good faith negotiations within thirty (30) days after such matter is referred to such officers. In the event such designated officers are not able to resolve such dispute within such thirty (30)-day period, then either of such designated officers may, but shall not be obligated to, request, within five (5) business days after the expiration of such period, that the Parties attempt non-binding mediation of any such matter for a period not to exceed thirty (30) days. Upon any such request, the Parties shall participate in good faith in such non-binding mediation. If the matter remains unresolved after such thirty (30)-day mediation period, or if neither of such designated officers so requests such non-binding mediation, then any such unresolved matter shall be resolved as set forth in Section 16.1(b) or Section 16.1(c), as applicable.

(b) Any Expert Matter shall be resolved by expedited arbitration by an Expert as follows:

(1) Upon written request by either Party to the other Party, the Parties shall promptly negotiate in good faith to appoint an appropriate Expert. If the Parties are not able to agree within five (5) days after the receipt by a Party of the written request in the immediately preceding sentence, the CPR Institute for Dispute Resolution, or such other similar entity as the Parties may agree, shall be responsible for selecting an Expert within seven (7) days of being approached by a Party. The fees and costs of the Expert and the CPR Institute for Dispute Resolution (or such other entity) shall be borne equally by Nuvelo and Bayer.

(2) Within fifteen (15) days after the designation of the Expert, the Parties shall each simultaneously submit to the Expert and one another a written statement of their respective positions on such disagreement. Each Party shall have five (5) business days from receipt of the other Party’s submission to submit a written response thereto, which shall include any scientific and technical information in support thereof. The Expert shall have the right to meet with the Parties, either alone or together, as necessary to make a determination.

(3) No later than thirty (30) days after the designation of the Expert, the Expert shall make a determination and shall provide the Parties with a written statement setting forth the basis of the determination. The decision of the Expert shall be final, binding and conclusive, absent manifest error.

(c) Any unresolved dispute that is not an Expert Matter shall, at the election of either Party, be decided by litigation in accordance with Section 16.2. Notwithstanding the above, either Party will be entitled at all times and without delay to seek equitable relief, provided that such relief is sought exclusively from a court as provided in Section 16.2.

16.2 Governing Law; Judicial Resolution. Resolution of all disputes arising out of or related to this Agreement, or the performance, enforcement, breach or termination of this Agreement and any remedies relating thereto, will be governed by and construed under the substantive laws of the State of New York as applied to agreements executed and performed entirely in the State of New York by residents of the State of New York, without regard to conflicts of law rules. Subject to Section 16.1, each Party irrevocably and unconditionally consents to the exclusive jurisdiction of the courts of general jurisdiction of the State of New York and the United States District Court for the Southern District of New York (collectively, the “Courts”), for any action, suit or proceeding (other than appeals therefrom) solely for a dispute arising out of this Agreement, and agrees not to commence any action, suit or proceeding (other than appeals therefrom) solely for disputes arising out of this Agreement except in such courts. Submission to United States jurisdiction is for the limited purpose of disputes arising out of this Agreement and does not create general jurisdiction. Each party hereby consents to the jurisdiction of the Courts and waives any other venue to which it may be entitled by virtue of domicile or otherwise.

16.3 Patent and Trademark Dispute Resolution. Notwithstanding the above Section 16.2, as between the Parties, any dispute, controversy or claim relating to the scope, validity, enforceability, inventorship or ownership of intellectual property rights shall be submitted by either Party to a court of competent jurisdiction in the country in which such rights apply.

ARTICLE 17

GENERAL

17.1 Force Majeure. Both Parties will 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 will be continued so long as the condition constituting Force Majeure continues and the nonperforming Party uses reasonable efforts to remove the condition. When such circumstances arise, the Parties will discuss what, if any, modification of the terms of this Agreement may be required in order to arrive at an equitable solution. Notwithstanding anything to the contrary, failure to fulfill payment obligations may only be excused under this Section 17.1 if the actual payment process is affected by the Force Majeure.

17.2 Notices. Any notice required or permitted to be given under this Agreement will be in writing, will specifically refer to this Agreement and will be deemed to have been sufficiently given for all purposes if mailed by first class certified or registered mail, postage prepaid, express delivery service or personally delivered or, if sent by facsimile, electronic transmission is confirmed. Unless otherwise notified in writing, the mailing addresses and fax numbers for notice of the Parties will be as described below.

17.3 Maintenance of Records. Each Party will keep and maintain all records required by law or regulation with respect to Licensed Product and will make copies of such records available to the other Party upon request.

17.4 No Strict Construction. This Agreement has been prepared jointly and will not be strictly construed against either Party.

17.5 Assignment. Other than as set forth in Section 2.4 with respect to Bayer’s right to grant Sublicenses under this Agreement and in Sections 13.4(d) and 15.2(d) with respect to the possible assignment of Nuvelo’s rights under this Agreement to Amgen, Inc., neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other, except that a Party may make such an assignment without the other Party’s consent to Affiliates or to an entity that acquires all or substantially all of the assets of such Party to which this Agreement pertains, whether in a merger, consolidation, reorganization, acquisition, sale or otherwise, so long as such entity shall assume (expressly in writing or by operation of law) the performance of all of the terms of this Agreement. Notwithstanding the foregoing, Nuvelo shall provide written notice to Bayer of any proposed acquisition by a Third Party of all or substantially all of the assets of Nuvelo to which this Agreement pertains sufficiently in advance of any such acquisition as to allow Bayer a reasonable opportunity to make a counteroffer to such Third Party acquisition. This Agreement will be binding on the successors and assigns of the assigning Party, and the name of a Party appearing herein will be deemed to include the name(s) of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement. Any assignment or attempted assignment by either Party in violation of the terms of this Section 17.5 will be null and void and of no legal

effect. The assigning Party will forward to the other Party a copy of those portions of each fully executed assignment agreement that relate to the assumption of the rights and responsibilities of the assigning Party, within sixty (60) days of the execution of such assignment agreement.

17.6 Performance by Affiliates. Each of Nuvelo and Bayer acknowledge that obligations under this Agreement may be performed by Affiliates of Nuvelo and Bayer. Each of Nuvelo and Bayer guarantee performance of this Agreement by its Affiliates, notwithstanding any assignment to Affiliates in accordance with Section 17.5 of this Agreement. Wherever in this Agreement the Parties delegate responsibility to Affiliates or local operating entities, the Parties agree that the Affiliates/entities may not make decisions inconsistent with this Agreement, nor amend the terms of this Agreement or act contrary to its terms in any way. Bayer will forward to Nuvelo a copy of each fully executed sublicense agreement within sixty (60) days of the execution. In case any Affiliate of a Party materially breaches this Agreement, the non-breaching Party will have the right to bring a cause of action directly against the other Party whether or not its Affiliate is named as a defendant in that action.

17.7 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument.

17.8 Severability. If any one or more of the provisions of this Agreement are held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, such provisions will be considered severed from this Agreement and will not serve to invalidate any remaining provisions hereof. The Parties will 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, as evidenced by the terms of this Agreement in accordance with Section 17.8, may be realized.

17.9 Headings. The headings for each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Unless otherwise specified, (a) references in this Agreement to any Article, Section or Exhibit will mean references to such Article, Section or Exhibit of this Agreement, (b) references in any Section to any clause are references to such clause of such Section, and (c) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally executed or, if subsequently varied, replaced or supplemented from time-to-time, as so varied, replaced or supplemented and in effect at the relevant time of reference thereto.

17.10 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

17.11 Independent Contractors. The relationship between Bayer and Nuvelo created by this Agreement is one of independent contractors. This Agreement does not create any agency, distributorship, employee-employer, partnership, joint venture or similar business relationship between the parties. Neither Party is a legal representative of the other Party, and neither Party

can assume or create any obligation, representation, warranty or guarantee (express or implied) on behalf of the other Party for any purpose whatsoever. Each Party will use its own discretion and will have complete and authoritative control over its employees and the details of performing its obligations under this Agreement.

17.12 No Benefit of Third Parties. The representations, warranties, covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns, and they will not be construed as conferring any rights on any Third Parties.

17.13 Use of Name. Except as expressly provided in this Agreement, no Party hereto will use, and no rights are granted in or to, the names or Trademarks (including the names “Nuvelo” and “Bayer”), physical likeness, employee names or owner symbol of the other Party for any purpose (including, without limitation, private or public securities placements) without the prior written consent of the affected Party, such consent not to be unreasonably withheld or delayed so long as the use of such name is limited to an objective statement of fact rather than for endorsement purposes. Neither Party will use any Trademark which either substantially resembles or is confusingly similar to, misleading or deceptive with respect to, or which dilutes any of the other Party’s Trademarks in connection with the subject matter of this Agreement.

17.14 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter will not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

17.15 Export Requirements. It is understood and acknowledged that the transfer of certain commodities and technical data may be subject to United States laws and regulations controlling the export of such commodities and technical data, including all Export Administration Regulations of the United States Department of Commerce. Each Party hereby agrees and by entering into this Agreement gives written assurance that it will comply with all United States laws and regulations controlling the export of commodities and technical data within Information and Materials, that it will be solely responsible for any violation of any such laws and regulations by itself, its Affiliates or its Sublicensees, and that it will indemnify, defend and hold the other Party harmless from any liability in the event of any legal action of any nature occasioned by such violation, pursuant to Section 14.1 (in the case of Nuvelo) or Section 14.2 (in the case of Bayer).

17.16 Entire Agreement; Amendment. Except for the Mutual Confidential Disclosure Agreement dated November 15, 2005 between the Parties, this Agreement (including all Exhibits) sets forth the complete, final and exclusive agreement and 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. This Agreement may only be modified or supplemented in a writing expressly stated for this purpose and signed by an authorized officer of each Party (i.e., it may not be modified by any purchase order, change order, acknowledgment, order acceptance, standard terms of sale, invoice or the like).
