(c) The Manufacturing Costs of commercial supplies of Collaboration Product as well as the duty, freight, postage, shipping, transportation, insurance, warehousing and handling charges actually allowed or paid with regard to such Collaboration Product shall be included in the calculation of cost of goods sold as part of Commercialization Costs.

6.6 Facility Audits. The JDC shall propose and submit to the JSC for approval a schedule for periodic audit and inspection of the facilities of any Third Party contract manufacturer on at least an annual basis subject to the terms of any applicable existing contract with a Third Party contract manufacturer. Pursuant to the schedule approved by the JSC, or upon request of the JDC, the Lead Manufacturing Party shall conduct an inspection or audit of the facilities of such Third Party contract manufacturers. The Lead Manufacturing Party shall provide not less than [ * ] notice to the other Party of any planned inspection and such other Party shall be permitted to participate in any audit, provided that, if the consent of the Third Party contract manufacturer is required under the applicable contract to allow such other Party to participate in such audit, the Lead Manufacturing Party shall use Diligent Efforts to obtain such consent. Any inspection or audit requested by the JDC (other than pursuant to the schedule approved by the JSC) shall be conducted no more frequently than [ * ] at a given facility, and shall occur as promptly as possible following written notice by the JDC of its desire for such inspection or audit, but in no event shall such inspection commence later than [ * ] thereafter (unless such audit is triggered by a material safety or GMP non-conformance issue, in which case the audit may be conducted as frequently as necessary and the maximum notice period shall be [ * ] if permitted under the applicable contract). Costs associated with auditing shall be Development Costs or Commercialization Costs as applicable.

6.7 Quality Agreement. The Parties shall negotiate in good faith and enter into a quality agreement governing the quality control, quality assurance and validation of the commercial and clinical supply of Bulk API and Product.

7. OPT-OUT.

7.1 General. Each Party shall have the right to opt-out of all of its rights and obligations to Co-Develop and Co-Commercialize any Collaboration Product pursuant to Sections 7.2 and 7.3 below (an “Opt-Out Option”). In addition, each Party may also exercise its Opt-Out Option pursuant to Section 8.5, and may be deemed to have exercised its Opt-Out Option pursuant to Section 14.2(b). The Opt-Out Party may exercise its Opt-Out Option pursuant


[ * ] =		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 Exchange Act of 1934, as amended.

to Sections 7.2, 7.3 or 8.5 by providing a written notice (an “Opt-Out Notice”) to the Non-Opt-Out Party.

7.2 Opt-Out Option. Each Party may, on a Product-by-Product basis, exercise its Opt-Out Option with respect to any Collaboration Product by providing an Opt-Out Notice to the other Party during one of the following periods: (a) the period beginning with the [ * ] for such Collaboration Product and ending [ * ] later; (b) the period beginning with the [ * ] for such Collaboration Product and ending [ * ] later. In addition, Trubion may, on a Product-by-Product basis, exercise its Opt-Out Option with respect to any Collaboration Product by providing an Opt-Out Notice to Facet at any time after [ * ] after the [ * ] and prior to the [ * ] for such Collaboration Product. Each such Opt-Out Notice shall identify the Collaboration Product for which the Opt-Out Party is exercising the Opt-Out Option (the “Opt-Out Product”). If a Party is deemed to have exercised its Opt-Out Option pursuant to Section 14.2(b), all Collaboration Products shall be deemed Opt-Out Products and Royalty Products.

7.3 Opt-Out Option Following Change of Control. If either Party (the “Acquired Party”) experiences a Change of Control, it shall inform the other Party within [ * ] following the effectiveness of such Change of Control and it shall use Diligent Efforts to arrange for the acquiring entity to discuss with the other Party the acquiring entity’s (a) intentions with respect to the Development and Commercialization of the Collaboration Products and (b) contemplated proposals for amending the Development Plan and, if applicable, Commercialization Plan for each Collaboration Product, and the other Party may exercise its Opt-Out Option with respect to all Collaboration Products by providing an Opt-Out Notice to the Acquired Party or its successor in interest within [ * ] of such Change of Control and all Collaboration Products shall become Opt-Out Products on the Opt-Out Effective Date.

7.4 Opt-Out Effective Date. An Opt-Out Option shall become effective [ * ] after the Non-Opt-Out Party’s receipt of such Opt-Out Notice (the “Opt-Out Effective Date”). Notwithstanding the foregoing, if a Party, after uncured material breach, is deemed to have exercised its Opt-Out Option pursuant to Section 14.2(b), then both the date of the Opt-Out Notice and the Opt-Out Effective Date for such Opt-Out Option shall be deemed to be the date on which the other Party provides the notice under Section 14.2(b) to continue this Agreement and all Collaboration Products shall become Royalty Products on such date.

7.5 Consequences of Opt-Out.

(a) The Opt-Out Party’s obligations and rights to Co-Develop and Co-Commercialize a particular Opt-Out Product shall terminate upon the applicable Opt-Out Effective Date, and the Opt-Out Party shall have no liability for Development Costs or Commercialization Costs incurred by the Non-Opt-Out Party in respect of the Opt-Out Product(s) following the Opt-Out Effective Date, provided, however, that the Opt-Out Party shall remain liable for its share of (i) [ * ] for all [ * ] for the [ * ] that were [ * ] to the [ * ] to the extent that such [ * ] for such [ * ] by [ * ] the [ * ] therefor in the [ * ] that was [ * ] on the [ * ], (ii) all other [ * ] and all [ * ] with respect to the [ * ] the [ * ] in accordance and consistent with the [ * ] or [ * ], as applicable and [ * ], and (iii) all [ * ], including [ * ] and [ * ], [ * ] in connection with [ * ] and [ * ] under Section [ * ], to the extent related to [ * ], [ * ], [ * ] or [ * ] of the applicable [ * ] within the Field anywhere in the Territory [ * ] the [ * ] and [ * ] the [ * ]

for such activities for which [ * ] is [ * ] under Section [ * ] or Section [ * ] and to the extent provided in Section [ * ].

(b) The Non-Opt-Out Party may, in its sole discretion, elect to continue the Development and Commercialization of the Opt-Out Product by notice (the “Pursuit Notice”) to the Opt-Out Party. If the [ * ] does not [ * ] a [ * ] with respect to [ * ] within [ * ] following the [ * ] of the [ * ], the [ * ] shall not [ * ] to [ * ] the [ * ] and [ * ] of the [ * ] and the [ * ] to the [ * ] shall [ * ] with respect to that [ * ]. Notwithstanding the foregoing, if a Party is deemed to have exercised its Opt-Out Option pursuant to Section 14.2(b), then the Non-Opt-Out Party shall be deemed to have provided a Pursuit Notice to the Opt-Out-Party by providing a written notice of continuation of the Agreement pursuant to Section 14.2(b). If the Non-Opt-Out Party delivers a Pursuit Notice with respect to an Opt-Out Product [ * ] such [ * ] or is deemed to have delivered such Pursuit Notice, such Opt-Out Product shall become a Royalty Product, and:

(i) the Non-Opt-Out Party shall be solely responsible, at its sole cost and expense (except for those costs for which the Opt-Out Party remains responsible pursuant to Section 7.5(a)) for the Development of such Royalty Product, the preparation and filing of Regulatory Materials for such Royalty Product, the receipt of Regulatory Approval for such Royalty Product, and the Commercialization of such Royalty Product, in each case in the Field in the Territory. The Non-Opt-Out Party shall use Diligent Efforts to Develop and obtain Regulatory Approval for Royalty Products and to Commercialize such Royalty Products in the Field in the Major Market Countries;

(ii) the Non-Opt-Out Party will inform the Opt-Out Party of the status of the Non-Opt-Out Party’s Development and Commercialization of Royalty Products through [ * ] progress reports submitted in writing to the Opt-Out Party, provided that if the Opt-Out Party remains responsible for the costs of any [ * ] pursuant to Section 7.5(a), the Non-Opt-Out Party shall additionally provide [ * ] reports and invoices with respect to such [ * ];

(iii) the Opt-Out Party shall provide reasonable consultation and assistance during a period of [ * ] following the Opt-Out Party’s receipt of the Pursuit Notice or written notice of continuation of the Agreement pursuant to Section 14.2(b), (“Transition Assistance”) for the purpose of transferring or transitioning to the Non-Opt-Out Party, (i) all Facet Applied Know-How or Trubion Know-How, as applicable, which is reasonably necessary for the continued Development, Manufacture or Commercialization of the Royalty Product not already in the Non-Opt-Out Party’s possession in the form and format in which such Know-How is maintained by the Opt-Out Party or its Affiliate or subcontractor in the ordinary course of business, and (ii) at the Non-Opt-Out Party’s request, the Opt-Out Party shall use Diligent Efforts to assign to the Non-Opt-Out Party all then-existing Third Party agreements that relate solely to the Royalty Product, in the Territory, in the Field and are reasonably necessary for the Non-Opt-Out Party to continue researching, Developing, Manufacturing, or Commercializing such Royalty Product in the Territory, in the Field; provided, however, that the Opt-Out Party shall be required to assign any such agreement solely to the extent assignment is permitted by such agreement provided that the Opt-Out Party uses Diligent Efforts to obtain any consent necessary for such assignment, and the Opt-Out Party is not required to pay any consideration or commence litigation in order to effect an assignment of any such agreement to the Non-Opt-Out Party;

(v) all Committees except the JPC shall cease to have any rights, obligations or decision-making capabilities with respect to such Royalty Product and, if there are no Collaboration Products still being pursued at such time, shall disband until such time, if ever, that a Collaboration Product is being pursued. All decisions that were made by such Committees under this Agreement with respect to the Royalty Product prior to the Opt-Out Effective Date shall thereafter be made solely by the Non-Opt-Out Party consistent with such Party’s obligations under Section 7.5(b)(i). The JPC shall continue subject to Section 10.3 unless a Party has exercised or is deemed to have exercised its Opt-Out Option in respect of all Collaboration Products, in which case all decisions that were made by the JPC prior to the Opt-Out Effective Date shall be made solely by the Non-Opt-Out Party consistent with such Party’s obligations under Section 7.5(b)(i);

(vi) if the Opt-Out Party is the Lead Manufacturing Party of the Royalty Product(s), as part of and during the period of the Transition Assistance (1) the Non-Opt-Out Party shall have the right to require the Opt-Out Party to continue supplying Bulk API and finished Product for such Royalty Product(s) under the terms of Article 6 for a period of up to eighteen (18) months (provided that the Non-Opt-Out Party shall use Diligent Efforts to find one or more alternative suppliers for Bulk API and finished Product as soon as reasonably possible following the exercise of the Opt-Out Option), and (2) the Non-Opt-Out Party shall have the right to obtain transfer, and the Opt-Out-Party shall have the obligation to effect transfer, without undue delay, of any and all manufacturing technology included in the Facet Applied Know-How or Trubion Know-How, as applicable, that is reasonably necessary to enable the Non-Opt-Out Party to Manufacture, or have Manufactured such Royalty Product(s). The Non-Opt-Out Party automatically owns one-half (1/2) of any or all of the inventory in existence as of the Opt-Out Effective Date of Bulk API and/or finished Product for such Royalty Product (such inventory, the “Existing Inventory”). In addition, the Non-Opt-Out Party shall have the right to purchase the other half of the Existing Inventory from the Opt-Out Party by reimbursing the Opt-Out Party for the Manufacturing Costs with respect to such Existing Inventory. The Non-Opt-Out Party shall notify the Opt-Out Party within [ * ] after the Effective Opt-Out Date whether the Non-Opt-Out Party elects to exercise such right to purchase the other half of the Existing Inventory;

(vii) the Opt-Out Party shall, as promptly as commercially practicable, assign to the Non-Opt-Out Party all right, title and interest in and to the Marks owned by the Opt-Out Party that were used or intended to be used with the Royalty Products (excluding any

For the avoidance of doubt, only those Marks that have been (A) identified as the single designated lead candidate Xxxx for a non-commercialized Royalty Product, or (B) actually used in connection with a Commercialized Royalty Product, shall be assigned. The Non-Opt-Out Party shall be responsible for recording such assignment in the Territory with the appropriate Governmental Authority and will bear all costs associated with such assignment and recordation. The Opt-Out Party shall cooperate in facilitating such assignment and recordation by timely executing all necessary documents provided to it by the Non-Opt-Out Party;

(viii) in lieu of the Product Profit payments it would have received if the Opt-Out Party had not exercised its Opt-Out Option or the Opt-Out Party had not been deemed to have exercised its Opt-Out Option under Section 14.2(b) with respect to such Royalty Product, the Opt-Out Party shall receive from the Non-Opt-Out Party royalties on the Net Sales of the Royalty Product(s) as provided for under Section 9.5;

(ix) the Opt-Out Party shall use Diligent Efforts to effect the assignment or the granting of a sublicense or equivalent right of access to the Non-Opt-Out Party, whether through novation or sublicensing of such contracts or otherwise, of any and all rights under any contract between the Opt-Out Party and any Third Party that are reasonably necessary for the Non-Opt-Out Party to continue with Development or Commercialization of such Royalty Product, and the Non-Opt-Out Party shall reasonably cooperate in connection therewith, provided that if such assignment, novation or sublicense is not permissible, the Parties shall discuss in good faith potential alternatives that would enable the Non-Opt-Out Party to exercise at the Non-Opt-Out Party’s expense (on a pass-through basis) the rights and perform the obligations of the Opt-Out Party under such contracts with respect to such Royalty Product while minimizing the continuing obligations of the Opt-Out Party under such contract with respect to such Royalty Product, and, unless the Non-Opt-Out Party informs the Opt-Out Party in writing that it is [ * ] in [ * ] such [ * ] and [ * ] such [ * ] or it is [ * ] for the [ * ] to [ * ], the Opt-Out Party shall [ * ] such [ * ] in [ * ] for the [ * ] of such [ * ] to [ * ] the [ * ] to [ * ] with [ * ] or [ * ] of such [ * ]; and

[ * ] =		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 Exchange Act of 1934, as amended.

subject to Sections 3.5(a) and 3.5(b), to subcontractors or consultants to perform such Party’s assigned Development, Manufacturing or Commercialization responsibilities under this Agreement with respect to Collaboration Products, further provided that (A) such Party remains responsible for the work allocated to, and payment to, such subcontractors and consultants to the same extent it would if it were doing such work itself, (B) such sublicense shall be subject and subordinate to, and consistent with, the terms and conditions of this Agreement, (C) such sublicense shall not in any way diminish, reduce or eliminate any of such Party’s obligations under this Agreement, and (D) such Party uses Diligent Efforts to include in such sublicense agreement a provision which permits such Party to provide a copy of such sublicense agreement to the other Party, which copy may be redacted to exclude confidential information not related to the applicable Collaboration Product.

will promptly inform the Opt-Out Party in writing and shall take such action which in the Non-Opt-Out Party’s reasonable business judgment will address such default; provided, however, any such uncured material breach by such sublicensee of an obligation that would constitute a material breach of the Non-Opt-Out Party’s obligations under this Agreement shall be deemed an uncured material breach of the Non-Opt-Out Party hereunder unless the Non-Opt-Out Party cures such material breach within the time provided under Section 14.2.

8.4 No Implied Rights. Except as expressly provided in this Agreement, neither Party shall be deemed by estoppel or implication to have granted the other Party any license or other right with respect to any intellectual property of such Party.

8.5 Exclusivity. Except for the Development and Commercialization of Products pursuant to the terms of this Agreement, during the Term neither Party shall Develop or Commercialize any protein therapeutic, including any [ * ], that binds to the CD37 Antigen (or a [ * ]) [ * ] of [ * ] and wherein such protein therapeutic is [ * ] or [ * ] to [ * ] its [ * ] through [ * ] the [ * ] (or a [ * ]) (a “Competing Program”). In the event that, due to a Change of Control of a Party, such Party, or its successor in interest, is conducting a Competing Program during the Term of this Agreement, then such Party, or its successor in interest, shall either (a) exercise its Opt-Out Option with respect to all Collaboration Products by providing an Opt-Out Notice to the other Party; or (b) divest such Competing Program to a Third Party, in each case within [ * ] of such Change of Control.

8.6 [ * ]. Each Party shall promptly bring to the attention of the JSC (or the other Party if there is no JSC in place at the time) any [ * ] that such Party wishes to Develop and Commercialize during the Term. Upon the recommendation of the JSC (or the mutual agreement of the Parties if there is no JSC in place at the time), the Parties shall negotiate in good faith an agreement to Develop and Commercialize such [ * ] on commercially reasonable terms.

8.7 Third Party Licenses. If the JPC determines that it is advisable or necessary to obtain a license (“Future Third Party License”) to any intellectual property right that is owned or controlled by a Third Party and is reasonably necessary or useful to the Development, Manufacture, or Commercialization of a Collaboration Product, the JPC shall so advise the JSC. If the JSC determines to seek a license, the JSC shall designate a Party to negotiate the terms on which such a Third Party license would be granted and to serve as the primary point of contact with the applicable Third Party licensor following the execution of the license agreement. Upon approval of the terms of such Future Third Party License by the JSC, the designated Party may execute such Future Third Party License and any payments that become due pursuant to a Future Third Party License agreement executed pursuant to this Section 8.7 will be treated as Development Costs or Commercialization Costs, as applicable, if incurred prior to the Opt-Out Effective Date or after the Opt-Out Effective Date but with respect to a Collaboration Product. If a Party delivers or is deemed to have delivered a Pursuit Notice for a Collaboration Product, any payments arising under a Future Third Party License from the Development, Manufacturing or Commercialization of the applicable Royalty Product shall be paid by such Non-Opt-Out Party, subject to Section 9.5(e)(iii).

9.3 Development Milestone Payments. Facet shall make milestone payments (each a “Milestone Payment”) to Trubion based on the first achievement of each milestone event in the Field, in the Territory for each Product as set forth in this Section 9.3. No Milestone Payment shall be made twice with respect to the same Product. For the purposes of this Section 9.3, two Products are deemed the “same Product” if one Product contains, as its active pharmaceutical ingredient, (i) the same [ * ] or [ * ] that is [ * ] in the [ * ], (ii) a [ * ] that is a [ * ] or [ * ] form of the [ * ] or [ * ] that is [ * ] in the [ * ] or (iii) a [ * ] that is a [ * ] or [ * ] form of a [ * ] or [ * ] from which the [ * ] in the [ * ] was [ * ] or [ * ]. Facet shall pay to Trubion the amounts set forth below, within [ * ] after the first achievement of the corresponding milestone event with respect to the Product. Each Milestone Payment is non-refundable and non-creditable against any other payments due hereunder, provided that if the Development of a Product is abandoned, any Milestone Payments made with respect to such abandoned Product may be credited against the corresponding Milestone Payments payable on a Product which achieves such milestones after the abandonment of the other Product. For the purposes of this Section 9.3, the “[ * ]” of a Clinical Trial shall occur upon the [ * ] of the [ * ] in such [ * ], “[ * ]” and “[ * ]” shall be [ * ] by the [ * ] in advance with respect to such [ * ] in the [ * ] or, following [ * ] for the applicable [ * ], [ * ] by the [ * ] in advance with respect to such [ * ] in [ * ] for the [ * ]. Notwithstanding anything to the contrary in this Agreement, if Trubion is deemed pursuant to Section 14.2(b) to have exercised its Opt-Out Option with respect to all Products on account of an uncured material breach by Trubion, the amount of the milestone payments due pursuant to this Section 9.3 with respect to milestone events achieved by all Products after Facet has provided Trubion with written notice of continuation in accordance with Section 14.2(b) shall be reduced by [ * ].

9.4 Sharing of Product Profit.

(a) Allocation.

(b) FTE Records and Calculations. Each Party shall record its FTE effort for the Commercialization of each Collaboration Product to the extent that such FTE efforts are included in Commercialization Costs that are, or may in the future be, shared under this Agreement, and shall report such FTE effort to the JCC, on a Calendar Quarterly basis, in each case in a manner that allocates such FTE effort to the extent practicable to each applicable Collaboration Product. Except to the extent provided herein, each Party shall calculate and maintain records of FTE effort incurred by it in the same manner as used for other products commercialized by such Party in accordance with a methodology approved by the JSC. The JFC shall facilitate any reporting hereunder.

(c) Commercialization Costs Accounts. Each Party shall charge all Commercialization Costs as incurred by it or its Affiliates on its books and records in connection with each Commercialization Plan. Each Party shall provide the other Party with an interim quarterly report of monthly estimates for the current Calendar Quarter charges within [ * ] after the end of the second calendar month in each Calendar Quarter.

(d) Other Expenses. Any expenses incurred by a Party for Commercialization activities that do not fall within the definitions of Commercialization Costs shall be borne solely by such Party unless the JSC determines otherwise.

(e) Pre-existing Obligations. Unless otherwise determined by the JSC, any manufacturing obligations in existence prior to the Signing Date, such as manufacturing capacity reservation or other obligations described in Section 6.3, other than those disclosed in writing by the obligated Party prior to the Signing Date and specifically agreed upon by the Parties, will not be considered Commercialization Costs and will not be subject to expense sharing.

(f) Reporting. Within [ * ] after the end of each Calendar Quarter, commencing with the first Calendar Quarter in which the Parties are implementing a Commercialization Plan for a particular Collaboration Product, each Party shall report to the JCC and the JFC its gross sales and Commercialization Costs for such Collaboration Product in the Territory. In addition, each Party shall provide the JCC and the JFC with a monthly statement on a Product-by-Product and country-by-country basis of the amount of gross sales of Collaboration Products.

(g) Payment. Within [ * ] after receipt of such reports, the JFC shall provide for such Collaboration Product a consolidated financial statement setting forth the Product Profit for such Collaboration Product and calculating each Party’s fifty percent (50%) share of such Product Profit. Thereafter the following remittance obligations shall apply for such Collaboration Product depending on whether such Product Profit is positive or negative:

(i) If there is positive Product Profit for such Calendar Quarter, then one Party shall make a payment to the other Party within [ * ] following delivery of the financial statement referenced above in an amount that will cause each Party to have received an equal share of the Product Profit for such Calendar Quarter.

(ii) If there is negative Product Profit for such Calendar Quarter, then one Party shall make a payment to the other Party so that each Party will bear an equal share of the Product Profit for such Calendar Quarter. Such payment shall be made within [ * ] following delivery of the financial statement referenced above.

(h) Records. Each Party shall keep detailed records of the Commercialization Costs it incurs, including all supporting documentation for such expenses, and remits for payment. Each Party shall keep such records for at least [ * ] after the date that such expense was incurred.

If an underpayment exceeds [ * ] percent ([ * ]%) of the amounts that were to be paid to the Auditing Party, the Audited Party also shall reimburse the Auditing Party for all costs and reasonable out-of-pocket expenses incurred in conducting the audit. If such accounting firm concludes that the Audited Party overpaid the Auditing Party, the Auditing Party, within [ * ] of the date the Auditing Party receives such account’s report so concluding, will refund such overpayments to the Audited Party less the reasonable out-of-pocket costs incurred by the Auditing Party in conducting the audit.

(d) Confidentiality.

Except as otherwise provided in this Section 10.3, as between the Parties, Trubion shall have the sole right and authority to prepare, file, prosecute (including any oppositions, interferences, reissue proceedings, reexaminations and post-grant proceedings) and maintain the Trubion Core Patent Rights in any jurisdiction in the Territory, provided that decisions regarding any claims within the Trubion Core Patent Rights that claim the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and do not claim the [ * ] or [ * ] of [ * ] that is [ * ] shall be made by the JPC. Trubion shall provide Facet (i) a reasonable opportunity to review and comment on such filing and prosecution efforts regarding the Trubion Core Patent Rights in the Territory; (ii) a copy of each material communication received from any patent authority in the Territory regarding the Trubion Core Patent Rights, and (iii) drafts of any material filings or material responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. If Trubion determines in its sole discretion to abandon, cease prosecution or not maintain any Trubion Core Patent Right anywhere in the Territory, then Trubion shall provide Facet written notice of such determination at least [ * ] before any deadline for taking action to avoid abandonment (or other loss of rights) and shall provide Facet with the opportunity to prepare, file, prosecute and maintain such Trubion Core Patent Right in the affected countries of the Territory on behalf of Trubion. If Facet desires Trubion to file, in a particular jurisdiction in the Territory, a Trubion Core Patent Right that claims priority to (or is based on the subject matter of) another Trubion Core Patent Right, Facet shall provide written notice to Trubion requesting that Trubion file such patent application in such jurisdiction. If Facet provides such written notice to Trubion, Trubion shall either (i) file and prosecute such patent application and maintain any patent issuing thereon in such jurisdiction, or (ii) notify Facet that Trubion does not desire to file such patent application and provide Facet with the opportunity to file and prosecute such patent application and maintain any patent issuing thereon on behalf of Trubion. Facet’s rights under this Section 10.3 with respect to any Trubion Core Patent Right licensed to Trubion by a Third Party shall be subject to the rights of such Third Party to file, prosecute, and/or maintain such Trubion Core Patent Right. Facet shall be responsible for [ * ] percent ([ * ]%) of the out-of-pocket costs incurred by Trubion in the course of preparing, filing, prosecuting and maintaining the Trubion Core Patent Rights and such costs shall not be included in Development Costs or Commercialization Costs. If Facet provides written notice to Trubion that Facet is no longer interested in maintaining a license to a particular Trubion Core Patent Right in a particular country, Facet will not be responsible for any portion of the costs incurred by Trubion after the date of such notice in connection with the preparation, filing, prosecution or maintenance of such Trubion Core Patent Right in such country, and the license granted to Facet under such Trubion Core Patent Right in such country shall terminate upon the delivery of such notice. If Facet assumes responsibility for any Trubion Core Patent Rights, then all costs incurred by Facet in the course of preparing, filing, prosecuting and maintaining such Trubion Core Patent Rights shall be borne by Facet, without reimbursement by Trubion, and such costs shall not be included in Development Costs or Commercialization Costs. If Trubion has exercised or is deemed to have exercised its Opt-Out Option in respect of all Products under this Agreement pursuant to Section 7.2 , 7.3, 8.5 or 14.2(b), following the Opt-Out Effective Date, all costs incurred by Trubion in the course of preparing, filing, prosecuting and maintaining the Trubion Core Patent Rights shall be borne solely by Trubion.

[ * ] =		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 Exchange Act of 1934, as amended.

following the Opt-Out Effective Date, all costs incurred by Trubion in the course of preparing, filing, prosecuting and maintaining the Trubion Core Patent Rights shall be borne solely by Trubion and Facet shall not have any rights pursuant to this Section 10.3(a) with respect to the Trubion Core Patent Rights; provided, however, if Facet notifies Trubion in writing within [ * ] following the Opt-Out Effective Date, with respect to one or more Trubion Core Patent Rights, that Facet will continue to be responsible for [ * ] percent ([ * ]%) of the out-of-pocket costs incurred by Trubion in the course of preparing, filing, prosecuting and maintaining such Trubion Core Patent Right(s), then Facet will continue to have all rights set forth in this Section 10.3(a) with respect to such Trubion Core Patent Right(s).

(b) Trubion Product Patent Rights, Facet Product Patent Rights and Joint Patent Rights.

(i) This Section 10.3(b)(i) shall apply if neither Party has exercised its Opt-Out Option, or is deemed to have exercised its Opt-Out Option under Section 14.2(b). Decisions regarding the preparation, filing, prosecution, and maintenance of Trubion Product Patent Rights, Facet Product Patent Rights and Joint Patent Rights, as well as any claims within the Trubion Core Patent Rights that claim the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and do not claim the [ * ] or [ * ] of [ * ] that is [ * ], in any jurisdiction in the Territory shall be made by the JPC. The JPC shall designate a Party (the “Implementing Party”) to be responsible, using its in-house counsel or outside patent counsel reasonably acceptable to the other Party, to implement the decisions of the JPC regarding the preparation, filing, prosecution, and maintenance of such Patent Rights, provided that Trubion shall be the Implementing Party for Trubion Product Patent Rights and Facet shall be the Implementing Party for Facet Product Patent Rights. The Implementing Party shall provide the JPC (i) a reasonable opportunity to review and comment on such prosecution efforts regarding such Patent Rights in the Territory, (ii) a copy of each material communication received from any patent authority in the Territory regarding such Patent Rights, and (iii) drafts of any material filings or material responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. Each Party shall be responsible for fifty percent (50%) of the out-of-pocket costs incurred by the Parties in the course of preparing, filing, prosecuting and maintaining such Patent Rights and such costs shall be included in Development Costs if incurred prior to First Commercial Sale of a Collaboration Product or Commercialization Costs if incurred after First Commercial Sale of a Collaboration Product.

(ii) This Section 10.3(b)(ii) shall apply if a Party has exercised its Opt-Out Option, or is deemed to have exercised its Opt-Out Option under Section 14.2(b), the Non-Opt-Out Party has delivered or is deemed to have delivered a Pursuit Notice, and the Parties are not actively Developing or Commercializing any Collaboration Products. Subject to this Section 10.3(b)(ii), the Non-Opt-Out Party shall make and implement decisions regarding the preparation, filing, prosecution, and maintenance of Trubion Product Patent Rights, Facet Product Patent Rights and Joint Patent Rights, as well as any claims within the Trubion Core Patent Rights that claim the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and do not claim the [ * ] or [ * ] of [ * ] that is [ * ], in any jurisdiction in the Territory. The Non-Opt-Out Party shall provide the Opt-Out Party: (i) a reasonable opportunity to review and comment on such prosecution efforts regarding such Patent Rights in the Territory; (ii) a copy of material communications from any patent authority in the Territory regarding such Patent Rights; and (iii) drafts of any

material filings or material responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. If the Non-Opt-Out Party determines to abandon, cease prosecution or not maintain any such Patent Right anywhere in the Territory, then it shall provide the Opt-Out Party written notice of such determination at least [ * ] before any deadline for taking action to avoid abandonment (or other loss of rights) and shall provide the Opt-Out Party with the opportunity to assume the preparation, filing, prosecution and maintenance of such Patent Right in the affected countries of the Territory. Each Party shall be responsible for one hundred percent (100%) of the costs it incurs in the course of preparing, filing, prosecuting and maintaining such Patent Rights and such costs shall not be included in Development Costs or Commercialization Costs.

(iii) If a Party has exercised its Opt-Out Option and the Non-Opt-Out Party has delivered a Pursuit Notice, but the Parties still are actively Developing or Commercializing one or more Collaboration Products (i.e. Products for which neither Party has exercised its Opt-Out Option), then (i) the provisions of Section 10.3(b)(ii) shall apply to (1) all Joint Patent Rights, Trubion Product Patent Rights and Facet Product Patent Rights that claim the [ * ] or [ * ] of a [ * ] and [ * ] in each case in all jurisdictions in the Territory and (2) all claims within the Trubion Core Patent Rights that claim the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and do not claim the [ * ] or [ * ] of [ * ], and (ii) the provisions of Section 10.3(b)(i) shall apply to (1) any other Joint Patent Right, Trubion Product Patent Rights and Facet Product Patent Rights and (2) all claims within the Trubion Core Patent Rights that claim the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and do not claim the [ * ] or [ * ] of [ * ].

(c) Divisional Patent Application. At the request of Facet or at Trubion’s election, Trubion shall file a continuation or divisional patent application of any Trubion Core Patent Right that contains a claim that claims the [ * ] or [ * ] of [ * ] or [ * ] in the [ * ] and does not claim the [ * ] or [ * ] of [ * ] that is [ * ], including U.S. Patent Application Serial Number [ * ], if permitted by applicable Laws, shall pursue in such continuation or divisional patent applications claims specifically directed to one or more Products and shall not pursue in such continuation or divisional patent applications any claims specifically directed to the product known as [ * ] or any other product that is not a Product. Such continuation or divisional patent applications shall be deemed Trubion Product Patent Rights.

(d) Patents Licensed from Third Parties. If either Party licenses after the Signing Date any Patent Rights from a Third Party and such Patent Rights qualify as Trubion Patent Rights or Facet Product Patent Rights, then each Party’s rights under this Section 10.3 with respect to such Patent Rights shall be subject to the rights of such Third Party to prosecute, maintain and extend such Patent Rights.

10.4 Infringement Actions.

[ * ] =		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 Exchange Act of 1934, as amended.

the right to terminate the Agreement under Section 14.3 during the period between its receipt of the notice of a material breach and its cure of such material breach or the resolution of any dispute with respect thereto pursuant to Section 14.2(c); provided that if such dispute is resolved in the favor of such alleged breaching Party, such Party shall be entitled to exercise its Opt-Out Option pursuant to Section 7.2 or, in the case of Facet, its right to terminate the Agreement under Section 14.3 within [ * ] of such resolution if it was deprived of the ability to exercise its Opt-Out Option on account of this sentence.

(b) Continuation. If the non-breaching Party has the right to terminate this Agreement under Section 14.2(a), then, instead of terminating this Agreement, the non-breaching Party may elect to continue this Agreement by notice to the breaching Party, provided, however, if the non-breaching Party elects to continue this Agreement, upon written notice of continuation from the non-breaching Party, then the breaching Party shall be deemed to have exercised its Opt-Out Option and the notice pursuant to this Section 14.2(b) shall be deemed an “Opt-Out Notice” and a “Pursuit Notice” with respect to all Products under this Agreement regardless of whether such breach related to any particular Product and the provisions of Section 7.5 shall apply with respect to all Products under this Agreement and the breaching Party shall bear [ * ] percent ([ * ]%) of the reasonable expenses incurred by the non-breaching Party in the course of performing its transfer obligations pursuant to Sections 7.5(b)(iii), 7.5(b)(iv), 7.5(vi)(2) and 7.5(vii). The preceding sentence shall not in any event limit in any manner the non-breaching Party’s other remedies for an uncured material breach of this Agreement.

(c) Disputed Breach. If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a notice provided by the other Party in accordance with Section 14.2(a), and such alleged breaching Party provides the other Party notice of such dispute and its intention to seek arbitration or judgment by a court pursuant to Article 15 within such [ * ] period (or [ * ] period for failure to make any payment), then the non-breaching Party shall not have the right to terminate this Agreement under Section 14.2(a) unless and until an arbitrator or court, in accordance with Article 15, has determined that the alleged breaching Party has materially breached this Agreement and that such Party fails to cure such breach within [ * ] following such decision of such arbitrator or court (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [ * ] following such decision of such arbitrator or court). It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.

14.3 Termination by Facet at Will. Facet shall have the right to terminate this Agreement in its entirety upon [ * ] prior written notice to Trubion, provided that, within eighteen (18) months after the Signing Date, such notice shall only be effective if accompanied by the payment of a termination fee equal to Ten Million Dollars ($10,000,000.00). Notwithstanding anything to the contrary in this Agreement, Facet shall have no right to terminate this Agreement pursuant to the preceding sentence after Facet has been deemed to have exercised its Opt-Out Option on account of an uncured breach pursuant to Section 14.2(b).

14.4 Effects of Termination by Facet at Will. Upon termination of this Agreement by Facet under Section 14.3, the following shall apply (in addition to any other rights and obligations under this Agreement with respect to such termination):

Facet will not be obligated to maintain any Third Party license agreement in effect unless Trubion timely exercises its rights as provided in the foregoing sentence or to grant sublicenses under this Section 14.4(a), if Facet is prohibited from granting such sublicenses under its agreement(s) with its licensor(s), but shall be required to use Diligent Efforts to obtain permission to grant such a sublicense from any such licensor(s).

(b) Marks. Facet shall, as promptly as commercially practicable, assign to Trubion all of Facet’s right, title and interest in and to the Marks used or to be used with the Products (excluding any such Marks that include, in whole or part, any corporate name or logo of Facet or its Affiliates or permitted sublicensees), including any goodwill associated therewith. For the avoidance of doubt, only those Marks which have been (i) identified prior to the effective date of termination of this Agreement as the single designated lead candidate Xxxx for a non-commercialized Product, or (ii) actually used in connection with a Commercialized Product, shall be assigned. Trubion shall be responsible for recording such assignment in the Territory with the appropriate Governmental Authority and will bear all costs associated with such assignment and recordation. Facet shall cooperate in facilitating such assignment and recordation by timely executing all necessary documents provided to it by Trubion.

(c) Regulatory Materials. Facet shall transfer and assign to Trubion in the form and format in which such materials are maintained by Facet in the ordinary course of business, all Regulatory Materials for Products in the Territory that are Controlled by Facet or its Affiliates or permitted sublicensees.

(d) Transition Assistance. Facet shall, [ * ], provide Transition Assistance for the purpose of transferring or transitioning to Trubion, (i) in the form and format in which such Facet Applied Know-How is maintained by Facet in the ordinary course of business, all Facet Applied Know-How not already in Trubion’s possession, and (ii) at Trubion’s request, all then-existing Third Party agreements relating solely to Products hereunder and that Facet is able, using Diligent Efforts to, assign to Trubion, in each case, to the extent reasonably necessary for Trubion to continue researching, Developing, Manufacturing, or Commercializing Products, provided, however, that Facet shall be required to assign any such agreement solely to the extent assignment is permitted by such agreement, and Facet is not required to pay any consideration or commence litigation in order to effect an assignment of any such agreement to Trubion.

(e) Remaining Inventories. Trubion shall have the right to purchase from Facet [ * ] (less any portion of the cost previously shared by Trubion as a Development Cost or Commercialization Cost) any or all of the inventory of Bulk API and/or Products held by or for Facet or its Affiliates as of the effective date of termination pursuant to the terms of this Agreement or the Commercial Supply Agreement, as applicable. Trubion shall notify Facet within [ * ] after the effective date of termination whether Trubion elects to exercise such right.

14.5 Effect of Termination by Trubion for Uncured Breach. Upon termination of this Agreement by Trubion under Section 14.2(a), the licenses granted under Article 8 shall terminate. Notwithstanding the foregoing, Facet hereby grants Trubion, effective only upon such termination, a [ * ] license, with [ * ] to [ * ] of [ * ], under [ * ], to Develop, make, have made, use, import, export, offer for sale, sell and Commercialize any Products that are [ * ] or are [ * ] as of the [ * ] of [ * ] for the [ * ] in the [ * ]. In addition, Facet shall comply with Section 14.4(c).

Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration.

14.7 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Trubion and Facet are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code. The Parties agree that each Party, as licensee of certain rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the United States Bankruptcy Code.

15. DISPUTE RESOLUTION; LIABILITY.

15.1 General. Any controversy, claim or dispute arising out of or relating to this Agreement shall be settled, if possible, through good faith negotiations between the Parties. If, however, the Parties are unable to settle such dispute after good faith negotiations, the matter shall be referred to the Executive Officers to be resolved by negotiation in good faith as soon as is practicable but in no event later than [ * ] after referral.

15.2 Failure of Executive Officers to Resolve Dispute. If the Executive Officers are unable to settle the dispute after good faith negotiation in the manner set forth above or in Section 2.7, the matter (a) shall be resolved in accordance with Section 15.3, and (b) either Party may seek injunctive or other equitable relief in any court in any jurisdiction where appropriate.

15.3 Arbitration. Matters under Section 15.2 which are to be resolved through binding arbitration shall be settled by traditional arbitration or, for matters specifically identified in Section 2.7(c)(a), baseball arbitration, in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) then in effect, except to the extent such rules are inconsistent with this Section 15.3. The proceedings and decisions of the arbitrators shall be confidential, final and binding on the Parties, and judgment upon the award of such arbitrator(s) may be entered in any court having jurisdiction thereof.

(a) The arbitration shall take place in [ * ] (if [ * ]) or [ * ] (if [ * ]).

(b) Traditional arbitration shall be conducted by an arbitration panel consisting of three (3) independent arbitrators, and the award or decision shall be rendered by a majority of the members of the arbitration panel. Each arbitrator shall have not less than fifteen (15) years of experience in the biotechnology or pharmaceutical industry and subject matter expertise with respect to the matter subject to arbitration. Each Party shall appoint one arbitrator, and the third arbitrator shall be selected jointly by the two arbitrators appointed by the Parties, unless the Parties otherwise agree as to the identity of the third arbitrator. If the two arbitrators appointed by the Parties are unable to agree upon the third arbitrator within [ * ] of any request for arbitration, such arbitrator shall be selected by the AAA. Any arbitrator chosen hereunder


[ * ] =		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 Exchange Act of 1934, as amended.

shall have educational training and industry experience sufficient to demonstrate a reasonable level of scientific, financial, medical and industry knowledge relevant to the particular dispute. The written decision of the arbitrators shall state the panel’s findings of material facts and the grounds for its conclusions and shall be final, conclusive and binding on the Parties and enforceable by any court of competent jurisdiction.

(c) Baseball Arbitration will be conducted by one (1) arbitrator who shall be reasonably acceptable to the Parties and who shall be appointed in accordance with AAA rules. If the Parties are unable to select an arbitrator within [ * ] of the notice that initiated the baseball arbitration, then the arbitrator shall be appointed in accordance with AAA rules. Any arbitrator chosen hereunder shall have educational training and industry experience sufficient to demonstrate a reasonable level of scientific, financial, medical and industry knowledge relevant to the particular dispute. Within [ * ] after the selection of the arbitrator, each Party shall submit to the arbitrator and the other Party a proposed resolution of the dispute that is the subject of the arbitration, together with any relevant evidence in support thereof (the “Proposals”). Within [ * ] after the delivery of the last Proposal to the arbitrator, each Party may submit a written rebuttal of the other Party’s Proposal and may also amend and re-submit its original Proposal. The Parties and the arbitrator shall meet within [ * ] after the Parties have submitted their final Proposals (and rebuttals, if any), at which time each Party shall have [ * ] to argue in support of its Proposal. The Parties shall not have the right to call any witnesses in support of their arguments, nor compel any production of documents or take any discovery from the other Party in preparation for the meeting. Within [ * ] after such meeting, the arbitrator shall select one of the final Proposals so submitted by one of the Parties as the resolution of the dispute, but may not alter the terms of either final Proposal and may not resolve the dispute in a manner other than by selection of one of the submitted final Proposals. If a Party fails to submit a Proposal within the initial [ * ] time frame set forth in the fourth sentence of this Section 15.3(c), the arbitrator shall select the Proposal of the other Party as the resolution of the dispute. Any time period set forth in this Section 15.3(c) may be extended by mutual agreement of the Parties.

(d) Each Party shall bear its own costs and expenses (including legal fees and expenses) relating to the arbitration proceeding, except that the fees of the arbitrator(s) and other related costs of the arbitration shall be shared equally by the Parties, unless the arbitrator(s) determine(s) that a Party has incurred unreasonable expenses due to vexatious or bad faith positions taken by the other Party, in which event the arbitrator(s) may make an award of all or any portion of such expenses so incurred.

(e) The arbitrator(s) shall be required to render their decision in writing and to comply with, and their award shall be limited by, any express provisions of this Agreement relating to damages or the limitation thereof. No arbitrator shall have the power to award punitive damages under this Agreement regardless of whether any such damages are contained in a Proposal, and such award is expressly prohibited.

15.4 Patent and Trademark Disputes. Notwithstanding Section 15.2, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Patent Rights or trademark rights covering the manufacture, use, importation, offer for sale or sale of Products shall be submitted to a court of competent jurisdiction in the country in which such Patent Rights or trademark rights were granted or arose.

It shall notify the other Party promptly should such circumstances arise, giving an indication of the likely extent and duration thereof, and shall use all Diligent Efforts to resume performance of its obligations as soon as practicable; provided, however, that neither Party shall be required to settle any labor dispute or disturbance.

Except as expressly limited by the terms of this Agreement, no failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No provision of this Agreement shall be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party.

Manufacturing and Process Development Plans

Manufacturing History

[ * ] Product ([ * ] of [ * ])

The [ * ] of [ * ] which is [ * ] in the [ * ] was manufactured at [ * ] ([ * ]) [ * ] ([ * ]), where about [ * ] of the product ([ * ]) were made in [ * ].

The [ * ] and [ * ] used to produce this [ * ] were a [ * ] with the [ * ] and [ * ] using [ * ] of [ * ] and [ * ] with [ * ]. The [ * ] of [ * ] containing the [ * ] was prepared at [ * ] and supplied to [ * ] ([ * ]) to prepare the [ * ] ([ * ]). The [ * ] was [ * ] by [ * ] and is [ * ] at [ * ].

The manufacturing process (referred to as [ * ]) was [ * ] at [ * ] and [ * ] to [ * ] for [ * ]. [ * ] standard [ * ] of [ * ] was generated at [ * ] in [ * ] during the [ * ] of the [ * ] to [ * ]. Subsequently, [ * ] manufactured the [ * ] of [ * ] in a [ * ], followed by [ * ], [ * ], and [ * ]. The [ * ] had a [ * ] of [ * ]. The ensuing overall recovery of [ * ] was [ * ], with a total of [ * ] of [ * ] generated.

The [ * ] of this [ * ] of [ * ] was packaged as a [ * ] for [ * ]. Each of the [ * ] contains [ * ] of [ * ] (or [ * ]) in the [ * ], as shown in the following table. The [ * ] system is a [ * ], with a [ * ], [ * ] with an [ * ] with a [ * ]. The [ * ] are [ * ] at [ * ] at [ * ] ([ * ]).

[ * ] of this [ * ] to [ * ] standard [ * ] by [ * ] and [ * ] has been established, and an [ * ] to [ * ] on [ * ] to pave the way for [ * ] the [ * ] to the [ * ].

Further [ * ] Plans

The current [ * ] process with [ * ] of about [ * ] and [ * ] of [ * ] is suitable for [ * ] for [ * ] and represnts the [ * ] for [ * ] of [ * ]. However, improvements to [ * ] and [ * ] are [ * ] to further [ * ] and [ * ] in [ * ] manufacturing. [ * ] changes, such as [ * ] to [ * ] materials ([ * ], etc.), will [ * ]. Throughout these [ * ], the [ * ] of the product from the [ * ] to the current [ * ] in [ * ] will be demonstrated.

Work is currently under way in [ * ] to [ * ] the [ * ] of the [ * ] process. So far, areas already successful have been:

	•		To [ * ] the [ * ] of [ * ] (currently at [ * ]) in the [ * ] process leading to the [ * ] to allow [ * ];

	•		To [ * ] the [ * ] of [ * ] in the [ * ] to achieve [ * ]

	•		To design a process with [ * ] for [ * ].

With some of these changes [ * ], a [ * ] process [ * ] in the [ * ] and of [ * ] to [ * ] has already been demonstrated in [ * ] and will shortly be tested with [ * ].

The [ * ] of the [ * ] process will also be examined. Attempts are currently being made to:

For the drug product, [ * ] efforts will look into [ * ] of [ * ] in [ * ], and [ * ] through:

	•		[ * ] the product [ * ] to [ * ] and [ * ] in [ * ] to get a [ * ] of [ * ] ([ * ] data indicate [ * ] of [ * ] or [ * ] are [ * ]). The need for this effort will be assessed in light of the intended [ * ] in consulation with the program team.

	•		Assessing [ * ] of [ * ]. The current [ * ] capacity at [ * ] ([ * ]) is in the process of being [ * ] which would offer the possibility of [ * ].

	•		An evaluation of [ * ] data on [ * ] would be done to assess [ * ] of a [ * ] should that be considered desirable for [ * ] purposes.

In the area of [ * ], the following [ * ] will be investigated as [ * ] to the [ * ] process:

	•		A [ * ] to determine [ * ] of the [ * ] in various process [ * ], including [ * ] and [ * ];

	•		A [ * ];

	•		Other [ * ] for [ * ] characterization of [ * ] and [ * ] for various [ * ] evaluations [ * ] by [ * ] and [ * ] and [ * ] for various [ * ] and [ * ]

Clinical Drug [ * ]

The current [ * ] drug product ([ * ], [ * ]) will be used in the Phase [ * ] study. Additional drug product ([ * ]) from the [ * ] manufacturing process is expected in [ * ]. [ * ] between the [ * ] and the [ * ] has been established and an [ * ] for the [ * ] of [ * ] on [ * ]. The timing of [ * ] will depend on [ * ] needs; at a minimum, a [ * ] in [ * ] will be [ * ] to [ * ] the [ * ] in [ * ].

For planning purposes, the best estimate of [ * ] at this time is assumed to be [ * ], for a total of [ * ]. The table on the next page lists the projected material requirements for the [ * ] in [ * ].

(d) Restricted Securities. Purchaser understands that the Shares have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act, which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of Purchaser’s representations as expressed in Section 4.1(c). Purchaser understands that the Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, Purchaser must hold the Shares indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Shares, and on requirements relating to the Company that are outside of Purchaser’s control.

(e) Legend. Purchaser understands that the Shares may bear the following legend:

THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

(f) Accredited Investor. Purchaser is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

(g) Investment Experience. Purchaser has such knowledge and experience in financial and business matters that Purchaser is capable of evaluating the merits and risks of the investment in the Shares.

(h) Trading in Company Common Stock. Since January 1, 2009, except pursuant to this Agreement, neither Purchaser nor any affiliate of Purchaser has directly, or indirectly through an agent, broker, financial advisor or other third party, sold, bought, made any short sale of, loaned, granted or received any option for the purchase or sale of, or otherwise directly acquired or disposed of any securities of the Company, whether on the NASDAQ Global Market or otherwise.

5. COVENANTS OF THE COMPANY

The Company covenants and agrees with Purchaser that from and after the Execution Date:


[ * ] =		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 Exchange Act of 1934, as amended.

108

5.1 Registration Rights.

(a) At any time after the date that is six (6) months after the Execution Date, upon the written request of Purchaser, the Company shall prepare and file, as expeditiously as reasonably possible, a registration statement under the Securities Act (“Registration Statement”) on Form S-3 (“Form S-3”) covering the resale of the Shares. In the event that Form S-3 is unavailable for such a registration, then the Company will (i) file a Registration Statement on such form as is then available to effect a registration of all of the Shares, and (ii) undertake to register the Shares on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Shares has been declared effective by the SEC. The Company shall use its reasonable best efforts to have the Registration Statement declared effective by the SEC as soon as practicable. On the business day following the effective date of such Registration Statement, the Company shall file with the SEC in accordance with Rule 424 under the Securities Act the final prospectus to be used in connection with sales pursuant to such Registration Statement. If for any reason the SEC does not permit all of the Shares to be included in such Registration Statement, or for any other reason any Shares are not then included in a Registration Statement filed pursuant to this Agreement, then the Company shall prepare, and, as soon as practicable, file with the SEC an additional Registration Statement covering the resale of all Shares not already covered by an existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. The Company shall use its reasonable best efforts to cause each such Registration Statement to be declared effective under the Securities Act as soon as possible. On the business day following the effective date of such Registration Statement, the Company shall file with the SEC in accordance with Rule 424 under the Securities Act the final prospectus to be used in connection with sales pursuant to such Registration Statement.

(b) If, at any time before October 17, 2015, the Company decides to register any of its securities for its own account or for the account of others, then the Company will promptly give Purchaser written notice thereof and will use its reasonable best efforts to include in such registration all or any part of the Shares requested by Purchaser to be included therein. This requirement does not apply to Company registrations on Form S-4 or S-8 or their equivalents relating to equity securities to be issued solely in connection with an acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans. Purchaser must give its request for registration under this paragraph to the Company in writing within 15 days after receipt from the Company of notice of such pending registration. If the registration for which the Company gives notice is an underwritten public offering, the Company will so advise Purchaser as part of the above-described written notice. If the managing underwriter of any proposed underwritten public offering advises the Company that the total amount of shares of Common Stock that Purchaser and any other persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Stock offered or the market for the Common Stock, then the shares of Common Stock to be included in such underwritten offering shall include the number of shares of Common Stock that such managing underwriter advises the Company can be sold without having such adverse effect, with such number to be allocated (i) first, among the Company and the investors who are party to that certain Amended and Restated Investor Rights Agreement, dated July 13, 2004 (the “Existing XXX”), by and among the Company and the investors set forth on Exhibit A thereto, pursuant to the terms thereof; (ii) second, to Purchaser; and (iii) third, to any other person holding Company securities


[ * ] =		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 Exchange Act of 1934, as amended.

109

who may also be including any such securities for sale in such underwritten offering. No registration rights that further limit or subordinate the rights of Purchaser to register the Shares will be granted by the Company until one or more registration statements covering all of the Shares have become effective.

(c) The Company will file all reports required to be filed by the Company with the SEC in a timely manner so as to preserve its eligibility for the use of Form S-3.

5.2 Consents. The Company shall use its commercially reasonable efforts to procure, in a timely manner upon reasonable terms and conditions, all consents and approvals, complete all filings, registrations and certificates, and satisfy all other requirements prescribed by Law, which are necessary to consummate the transactions contemplated in this Agreement prior to the Closing Date.

5.3 Cooperation. The Company shall cooperate fully, completely and promptly with Purchaser in connection with satisfying all conditions to, and effecting the transactions contemplated by, this Agreement.

5.4 Commercially Reasonable Efforts. The Company shall use its commercially reasonable efforts to cause the conditions set forth in Sections 7.1 and 7.3 to be satisfied on or prior to the Closing Date.

5.5 Further Assurances. The Company agrees to use its commercially reasonable efforts to take, or cause to be taken, any appropriate action, and do, or cause to be done, all things necessary, proper or advisable under any applicable Law to consummate and make effective the sale and assignment of the Shares contemplated by this Agreement as promptly as practicable after the Execution Date.

5.6 Operation of Business. The Company agrees prior to the Closing to (a) maintain its existence in good standing under applicable Law, (b) conduct its operations in all material respects only in the ordinary and usual course of business consistent with past practice and (c) not take any action or establish a record date for the taking of any action with respect to any stock split, stock dividend, combination of shares, recapitalization or other change in the structure of the Company which affects or relates to the Common Stock.

5.7 Form D; Blue Sky Laws. The Company will timely file a Notice of Sale of Securities on Form D with respect to the Shares, under Regulation D promulgated by the Commission under the Securities Act. The Company will, on or before the Closing Date, take such action as it reasonably determines to be necessary to qualify the Shares for sale to Purchaser under this Agreement under applicable securities (or “blue sky”) laws of the states of the United States (or to obtain an exemption from such qualification).

5.8 Issuance of Certificates. The Company will, or will instruct its transfer agent to, issue certificates registered in the name of Purchaser or its nominee, for the Shares. All such certificates will bear the restrictive legend described in Section 4.1(e), except as otherwise specified in Section 5.9. The Company will not give to its transfer agent any instruction other than as described in this Section 5.8 and Section 5.9 and stop transfer instructions to give effect to Section 4.1(e) (prior to registration of the Shares under the Securities Act). Nothing in this


[ * ] =		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 Exchange Act of 1934, as amended.

110

Section 5.8 and Section 5.9 affects in any way Purchaser’s obligation to comply with all applicable prospectus delivery requirements, if any, upon resale of the Shares.

5.9 Unrestricted Securities. If, unless otherwise required by applicable state securities laws, (a) the Shares represented by a certificate have been registered under an effective Registration Statement, (b) Purchaser and/or its nominee provides the Company and its transfer agent with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Shares may be made without registration under the Securities Act and such sale may occur without restriction on the manner of such sale or transfer, (c) such holder provides the Company and its transfer agent with reasonable assurances that such Shares can be sold under Rule 144 promulgated by the SEC pursuant to the Securities Act, as such Rule may be amended from time to time, or any similar rule or regulation hereafter adopted by the SEC having substantially the same effect as such Rule (“Rule 144”), or (d) the Shares represented by a certificate can be sold without restriction as to the number of securities sold under Rule 144, the Company will permit the transfer of the Shares, and the Company will instruct its transfer agent to issue one or more certificates, free from any restrictive legend, in such name and in such denominations as specified by such holder. Notwithstanding anything herein to the contrary, the Shares may be pledged as collateral in connection with a bona fide margin account or other lending arrangement; provided, that such pledge will not alter the provisions of this Section 5.9 with respect to the removal of restrictive legends.

6. COVENANTS OF PURCHASER

Purchaser covenants and agrees with the Company that from and after the Execution Date:

6.1 Consents.
