2.4.1 (a) COMPANY shall have the right to grant and authorize sublicenses under the license and sublicense granted in Section 2.1 and 2.2, respectively, to any SUBLICENSEE, AFFILIATE or CMO, provided that: (i) under each sublicense, each such SUBLICENSEE, AFFILIATE or CMO shall be subject to terms and conditions that are subordinate to, and not in conflict with, the terms and conditions of this AGREEMENT as applicable; (ii) subject to Section 2.4.1(b), each sublicense shall, at NEKTAR AL’s option, terminate upon the termination or expiration of this AGREEMENT; (iii) COMPANY’s grant of any sublicense shall not relieve COMPANY from any of its obligations under this AGREEMENT; (iv) COMPANY shall remain liable for any breach of this AGREEMENT caused by a SUBLICENSEE, AFFILIATE or CMO; and (v) promptly after entering into any sublicense agreement with a SUBLICENSEE, COMPANY shall promptly provide NEKTAR AL with a copy of such sublicense agreement, the terms of which agreement may be redacted except to the extent reasonably necessary for NEKTAR AL to confirm compliance with this AGREEMENT.

(b) In the event of any termination of this AGREEMENT, other than as a result of expiration under Section 15.1 or termination under Sections 15.3 (but, in the case of a termination under Section 15.3 only with respect to a challenge of the NEKTAR AL PATENT RIGHTS, only with respect to challenge by the SUBLICENSEE) or 15.4, such sublicenses shall terminate unless NEKTAR AL consents to such sublicense surviving, which consent may be withheld at NEKTAR AL’s sole discretion; provided that (i) such sublicenses with SUBSTANTIAL PHARMACEUTICAL COMPANIES, up to a maximum of two (2) such SUBLICENSEES, shall survive and continue in effect without requiring such consent, (ii) in each case the survival of such sublicense shall be conditioned upon the SUBLICENSEE agreeing in writing to be bound by the terms of this Agreement as such terms apply to the SUBLICENSEE, such that the SUBLICENSEE is in direct privity and such SUBLICENSEE is responsible for payments that become due as a result of such SUBLICENSEE’s activities after the date of such termination, and (iii) if this AGREEMENT has been terminated by NEKTAR AL under Section 15.2, each such SUBLICENSEE shall (A) cure any default or breach of COMPANY that was the basis for such termination either: (1) within the cure periods provided for in Section 15.2 or, (2) if such SUBLICENSEE has notified NEKTAR AL in writing, prior to the expiration of the cure periods provided for in Section 15.2, that it wishes

-14-

to cure any default or breach of COMPANY that was the basis for such termination, then SUBLICENSEE shall cure any default or breach of COMPANY that was the basis for such termination within thirty (30) days after the date of such termination for nonpayment, or within ninety (90) days after the date of such termination for any other breaches or defaults, and (B) otherwise be in good standing with regard to its obligations under its sublicense, or have cured any default or breach under such sublicense within the cure period provided for therein. For such purposes, “SUBSTANTIAL PHARMACEUTICAL COMPANY” is a company that, on a consolidated basis, had revenues from sales of pharmaceutical products of at least One Hundred Million DOLLARS ($100,000,000) in the last full fiscal year prior to the grant of such sublicense by COMPANY.

2.4.2 Notwithstanding the provisions of Section 2.4.1, COMPANY may not sublicense any NEKTAR AL LICENSED TECHNOLOGY to a SUBLICENSEE that, at the time such sublicense is granted or such contract is entered into, is a competitor of NEKTAR AL. A competitor of NEKTAR AL shall mean any THIRD PARTY who is in the business of (a) manufacturing or supplying PEG or REAGENTS to THIRD PARTIES, or (b) attaching PEG or PEG derivatives to pharmaceutical or biotechnology products for THIRD PARTIES, including licensing to THIRD PARTIES intellectual property or technology pertaining to attachment of PEG or REAGENTS to pharmaceutical or biotechnology products; and which in each case is not a SUBSTANTIAL PHARMACEUTICAL COMPANY whose sales of pharmaceuticals, on a consolidated basis, were at least Five Billion DOLLARS ($5,000,000,000) in the last full fiscal year prior to the grant of such sublicense. The PARTIES further agree that on the EFFECTIVE DATE the companies listed in Schedule VIII, together with any additional entities proposed by COMPANY and approved in writing by NEKTAR AL (which approval will not be unreasonably withheld), are not competitors of NEKTAR AL.

2.4.3 Notwithstanding the provisions of Section 2.4.1, COMPANY may not sublicense any ENZON PATENTS to a PERSON that at the time such sublicense is granted is a party to a then-pending action for infringement of a patent owned or CONTROLLED by ENZON.

2.5 ENZON PATENTS. COMPANY agrees and acknowledges that the sublicense granted under Section 2.2 is subject to the following limitations and conditions:

2.5.1 COMPANY shall place appropriate patent and/or patent pending markings for the ENZON PATENTS on the SELECTED PRODUCT, or if such marking cannot be affixed to the SELECTED PRODUCT itself, on the packaging for such SELECTED PRODUCT, the content, form, size, location and language to be in accordance with the laws and practices of the country where such markings are required;

-15-

2.5.2 COMPANY shall have no enforcement rights with respect to the ENZON PATENTS;

2.5.3 Subject to any prior termination, such sublicense shall remain in effect until the expiration of the last-to-expire VALID ENZON PATENT CLAIM that, but for the grant of such sublicense, would be infringed by the manufacture, use, import, offer for sale, or sale of the SELECTED PRODUCT; and

2.5.4 Such sublicense shall terminate if NEKTAR AL’s rights to the ENZON PATENTS pursuant to the CROSS-LICENSE AGREEMENT with ENZON terminates for any reason.

2.6 NEKTAR AL Research Rights and Limitations. Notwithstanding anything to the contrary in this AGREEMENT and without limiting any other retained rights, the license and sublicense granted under Section 2.1 and 2.2, respectively, shall be subject to the retained right of NEKTAR AL and its AFFILIATES: (i) to practice the NEKTAR AL LICENSED TECHNOLOGY for the conduct of research and development of products that it is developing either itself or with others; (ii) to develop, make, have made, use, sell, offer for sale, import and license products other than SELECTED PRODUCT, including products containing SELECTED REAGENT; and (iii) to perform their respective obligations to THIRD PARTIES set forth in agreements existing as of the EFFECTIVE DATE.

2.7 No Implied Rights or Licenses. Neither PARTY grants to the other any rights or licenses, including without limitation to any NEKTAR AL LICENSED TECHNOLOGY or other intellectual property rights, whether by implication, estoppel or otherwise, except to the extent expressly provided for under this AGREEMENT. Other than as expressly provided for herein, COMPANY may not develop, make, have made, use, sell, offer for sale or import SELECTED REAGENT, nor may COMPANY copy, distribute, reverse engineer (by way of example but not limitation, by performing tests such as HPLC, gas chromatography or x-ray crystallography), self, lease, license or otherwise transfer, modify, adapt or create derivatives of SELECTED REAGENT. COMPANY shall ensure that all of its AFFILIATES, SUBLICENSEES, CMOS, contractors, agents and employees are subject to the same restrictions and limitations with respect to the SELECTED REAGENT as set forth in this Section 2.7. For purposes of clarity, it is understood that to “modify, adapt or create derivatives” shall mean to synthesize a REAGENT using the SELECTED REAGENT as its starting material or through a program of chemical synthesis specifically based on the SELECTED REAGENT. In addition, notwithstanding the foregoing, it is understood that COMPANY (and its AFFILIATES, SUBLICENSEES, CMOS, contractors, agents and employees) shall be free to conduct any testing and characterization of SELECTED PRODUCT following completion of the step of CONJUGATION of the SELECTED REAGENT to the THERAPEUTIC AGENT, including without limitation testing and characterization of the reaction mixture in which the SELECTED PRODUCT was

-16-

produced (where said reaction mixture may contain unreacted SELECTED REAGENT and/or THERAPEUTIC AGENT), that is reasonably necessary for COMPANY or its SUBLICENSEES to obtain MARKETING AUTHORIZATION in a jurisdiction, even if such testing and characterization necessarily includes the testing and characterization of SELECTED REAGENT. It is further understood that COMPANY shall be free to conduct any testing and characterization of the SELECTED REAGENT reasonably necessary for quality control and quality assurance purposes, including without limitation for purposes of determining conformance of a shipment with the SPECIFICATIONS. COMPANY agrees that it and its AFFILIATES and SUBLICENSEES may use all information and data generated by COMPANY as a result of conducting the testing and characterization of SELECTED PRODUCT permitted in this Section 2.7 to develop, manufacture, obtain MARKETING AUTHORIZATION in a jurisdiction and commercialize the SELECTED PRODUCT (including for quality control and quality assurance purposes in connection with SELECTED PRODUCT), and for no other purpose that is not expressly permitted under this Agreement.

2.8 Mutual Covenant. Each PARTY covenants and agrees that, with respect to SELECTED PRODUCT, (i) it and its AFFILIATES shall not use or practice the intellectual property rights licensed under this AGREEMENT except as expressly permitted by this AGREEMENT and (ii) any use or practice of the intellectual property rights licensed under this AGREEMENT except as expressly permitted by this AGREEMENT that results in material harm to the other PARTY shall constitute a material breach of this AGREEMENT. Notwithstanding the foregoing, each PARTY covenants and agrees to cease any such non-permitted use and to take all actions necessary to assign to the other PARTY any inventions made through use or practice of such PARTY’s intellectual property rights outside the scope of the license rights granted hereunder.

2.9 COMPANY Covenants.

2.9.1 COMPANY hereby represents and warrants that: (a) it is not a party to an action for infringement of a patent owned or CONTROLLED by ENZON that is pending on the EFFECTIVE DATE; and (b) it has not been in negotiations with ENZON for a license under the ENZON PATENTS with respect to the THERAPEUTIC AGENT.

2.9.2 COMPANY hereby covenants that it will refrain from judicially challenging the validity or enforceability of any ENZON PATENTS with respect to the SELECTED PRODUCT and will contractually restrict its AFFILIATES, SUBLICENSEES and CMOS from similarly challenging the validity or enforceability of the ENZON PATENTS with respect to the SELECTED PRODUCT. If COMPANY or its AFFILIATES, SUBLICENSEES or CMOS challenges the ENZON PATENTS that are sublicensed hereunder: (a) COMPANY shall pay for all attorney’s fees, costs of suit, and other out-of-pocket expenses incurred by ENZON and/or

-17-

NEKTAR AL in resisting or opposing such challenge if such challenge is not successful; and (b) COMPANY’s and its AFFILIATES’, SUBLICENSEES’ and CMOS’ sublicense rights to such ENZON PATENTS shall automatically terminate. The provisions of this Section 2.9.2 shall not apply if COMPANY or its AFFILIATES, SUBLICENSEES or CMOS challenge the validity or enforceability of any ENZON PATENTS that are not sublicensed hereunder as a defense against ENZON claiming that the manufacture, use or sale of products, other than the SELECTED PRODUCT, infringes PATENTS owned or CONTROLLED by ENZON.

2.9.3 COMPANY hereby covenants that it will not judicially challenge the validity or enforceability of any NEKTAR AL PATENT RIGHTS and will contractually restrict its AFFILIATES, SUBLICENSEES and CMOS from judicially challenging the validity or enforceability of the NEKTAR AL PATENT RIGHTS, in each case with respect to the SELECTED PRODUCT. If COMPANY or its AFFILIATES, SUBLICENSEES or CMOS judicially challenge the NEKTAR AL PATENT RIGHTS: (a) COMPANY shall pay for all attorney’s fees, costs of suit, and other out-of-pocket expenses incurred by NEKTAR AL in resisting or opposing such challenge if such challenge is not successful; and (b) COMPANY’s and its AFFILIATES’, SUBLICENSEES’ and CMOS’ license rights under the NEKTAR AL LICENSED TECHNOLOGY shall automatically terminate. The provisions of this Section 2.9.3 shall not apply if COMPANY or its AFFILIATES, SUBLICENSEES or CMOS challenge the validity or enforceability of any NEKTAR AL PATENT RIGHTS in a court of law as a defense against NEKTAR AL claiming that the manufacture, use or sale of products, other than the SELECTED PRODUCT, infringes PATENTS or PATENT APPLICATIONS owned or CONTROLLED by NEKTAR AL.

2.9.4 COMPANY hereby covenants that it will not use the SELECTED REAGENT other than to develop, manufacture and commercialize SELECTED PRODUCT (and not for any other product) as provided for in this AGREEMENT.

3. Disclaimer of Warranty. Except as provided in Sections 5.2, 11.1 and 11.2, NEKTAR AL PROVIDES NO WARRANTIES, EXPRESS OR IMPLIED, REGARDING THE NEKTAR AL LICENSED TECHNOLOGY, SELECTED REAGENT OR SELECTED PRODUCT (INCLUDING THE SUCCESSFUL DEVELOPMENT, REGISTRATION, MANUFACTURE OR COMMERCIALIZATION OF SELECTED PRODUCT), AND DISCLAIMS ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, TITLE, FITNESS FOR A PARTICULAR PURPOSE AND FREEDOM FROM INFRINGEMENT OF THIRD PARTY RIGHTS. NEKTAR AL FURTHER PROVIDES NO WARRANTY, EXPRESS OR IMPLIED, THAT THE PRACTICE OF THE INVENTIONS DESCRIBED IN THE NEKTAR AL PATENT RIGHTS WILL NOT INFRINGE THE INTELLECTUAL PROPERTY RIGHTS OF A THIRD PARTY.

-18-

4. Manufacture and Supply of SELECTED REAGENT

4.1 Exclusivity. NEKTAR AL shall manufacture and supply, and COMPANY shall purchase from NEKTAR AL, one hundred percent (100%) of COMPANY’s and COMPANY’s SUBLICENSEES’ requirements of SELECTED REAGENT, for the sole purpose of developing and manufacturing SELECTED PRODUCT pursuant to the license granted hereunder, subject only to Section 4.6. COMPANY’s failure to purchase one hundred percent (100%) of COMPANY’s and COMPANY’s SUBLICENSEES’ requirements of SELECTED REAGENT from NEKTAR AL for the purpose of developing and manufacturing SELECTED PRODUCT shall be a material breach of this AGREEMENT.

4.2 Pre-Commercial Supply. No later than thirty (30) days after the EFFECTIVE DATE, COMPANY shall provide NEKTAR AL with a six (6) quarter rolling forecast of its requirements of SELECTED REAGENT for the six (6) calendar quarters immediately following the EFFECTIVE DATE for research, pre-clinical development, clinical development (until the provisions of Section 4.3 begin to apply) and other activities prior to the earlier of the second PIVOTAL TRIAL for SELECTED PRODUCT or twelve (12) months prior to the anticipated filing of the first NDA, which forecast shall be an estimate only. COMPANY shall update such forecast at least thirty (30) days following the start of each calendar quarter.

4.3 Minimum Purchases and Rolling Forecast for Commercial Supply. At least ninety (90) days prior to the anticipated date of the earlier of either commencement of the second PIVOTAL TRIAL for SELECTED PRODUCT or twelve (12) months prior to the anticipated filing of the first NDA, COMPANY shall furnish NEKTAR AL with an eight (8) calendar quarter rolling forecast of its requirements of SELECTED REAGENT for SELECTED PRODUCT. Such eight (8) calendar quarter forecast shall begin 90 days after the furnishing of the first forecast with the required quantities for the first four (4) calendar quarters of such forecast constituting a binding order for supply of SELECTED REAGENT, and the forecast for the remaining four (4) calendar quarters to be an estimate only, which in all cases shall equal at least one hundred percent (100%) of COMPANY’s and COMPANY’s SUBLICENSEES’ requirements of SELECTED REAGENT. COMPANY shall update such forecast at least thirty (30) days prior to the commencement of the next and each successive calendar quarter. Notwithstanding the foregoing, NEKTAR AL shall only be bound to supply up to one hundred and twenty percent (120%) of the initial forecast covering any calendar quarter. In the event that the binding order portion of COMPANY’s forecast for a given calendar quarter exceeds one hundred and twenty percent (120%) of the initial forecast for such calendar quarter, the PARTIES shall meet in good faith to discuss how and whether NEKTAR AL can meet the revised forecast. Any and all forecasts provided by COMPANY to NEKTAR AL under this AGREEMENT shall be sent to the attention of NEKTAR AL’s Contract

-19-

Management. Upon the earlier of the initiation of the second PIVOTAL TRIAL for SELECTED PRODUCT or twelve (12) months prior to the anticipated filing of the first NDA, such forecasts shall be in full batch increments, provided that such full batch increments shall be an amount mutually agreed. For purposes of this AGREEMENT, commencement of a clinical trial shall be deemed to occur on the date on which SELECTED PRODUCT is first administered to the first patient or subject in such trial.

4.4 Purchase Orders. COMPANY shall, from time to time, provide NEKTAR AL with a written purchase order for amounts of SELECTED REAGENT for SELECTED PRODUCT to be provided by NEKTAR AL hereunder. Each such purchase order shall be sent to the attention of NEKTAR AL’s Contract Management and shall specify the quantity, requested packaging and requested delivery date of SELECTED REAGENT, as well as the location to which SELECTED REAGENT is to be shipped; provided, however, that in the case of purchase orders submitted for non-binding forecasted quantities of SELECTED REAGENT, COMPANY shall not designate in any such purchase order a delivery date that is less than five (5) months after the date of such purchase order. Upon the earlier of the initiation of the second PIVOTAL TRIAL for SELECTED PRODUCT or twelve (12) months prior to the anticipated filing of the first NDA, such purchase orders shall be in full batch increments, as described in Section 4.3 above. NEKTAR AL shall have each shipment of SELECTED REAGENT shipped pursuant to its standard shipping procedures and documentation. The terms and conditions of this AGREEMENT shall govern all purchase orders, notwithstanding the fact that a purchase order or the standard shipping document may provide for additional or different obligations of NEKTAR AL than the terms and conditions of this AGREEMENT. Any such additional or different terms in any such purchase order or shipping documents are hereby expressly rejected.

4.5 Fulfillment. To the extent that any orders for SELECTED REAGENT do not exceed one hundred and twenty percent (120%) of COMPANY’s initial forecast for a given calendar quarter, and to the extent forecasts and purchase orders are submitted as provided hereunder, NEKTAR AL shall fulfill these orders by the delivery date as agreed by the PARTIES in writing (or under accepted purchase orders), provided, however, that for orders submitted for non-binding forecasted quantities of SELECTED REAGENT, NEKTAR AL will not be obligated to accept a requested delivery date for an order that is less than five (5) months after the date such order is placed. Notwithstanding the foregoing, NEKTAR AL shall reasonably consider a request by COMPANY to accept a delivery date that is less than five (5) months after the date such order is placed. In addition, if NEKTAR AL cannot fulfill an order by the agreed upon delivery date, then NEKTAR AL shall promptly notify COMPANY in writing.

-20-

4.6 Failure to Supply.

4.6.1 If NEKTAR AL cannot supply at least eighty percent (80%) of the amount of SELECTED REAGENT ordered by COMPANY pursuant to Section 4.4 that is within the limits set forth in Section 4.3 in any two (2) consecutive calendar quarters by the time for delivery of such shipment provided in Section 4.5, and NEKTAR AL does not cure the deficiency within ninety (90) days after COMPANY so notifies NEKTAR AL in writing that a quantity of SELECTED REAGENT due for delivery has not been delivered, then NEKTAR AL shall be considered as having failed to manufacture and to sell to COMPANY the relevant quantity of SELECTED REAGENT (a “FAILURE”). NEKTAR AL shall, subject to this Section 4.6, work with COMPANY in good faith and select a qualified THIRD PARTY contract manufacturer (“CONTRACT MANUFACTURER”) reasonably acceptable to COMPANY, to make such quantity of SELECTED REAGENT that NEKTAR AL failed to supply for the duration of such FAILURE.

4.6.2 If a FAILURE occurs other than as a result of an event of force majeure (as described more fully in Section 20.1), NEKTAR AL shall bear any costs associated with transferring NEKTAR AL KNOW-HOW to such CONTRACT MANUFACTURER to enable it to manufacture and supply the SELECTED REAGENT in the event of a FAILURE.

4.6.3 lf a FAILURE occurs as a result of an event of force majeure, COMPANY shall bear any costs associated with transferring NEKTAR AL KNOW-HOW to such CONTRACT MANUFACTURER to enable it to manufacture and supply the SELECTED REAGENT in the event of a FAILURE.

4.6.4 If a FAILURE occurs for any reason, COMPANY shall pay for SELECTED REAGENT manufactured and supplied by CONTRACT MANUFACTURER at the price charged by CONTRACT MANUFACTURER for the manufacture and supply of SELECTED REAGENT, even if such price is higher than the price that was being charged by NEKTAR AL under this AGREEMENT for the SELECTED REAGENT at the time such FAILURE occurred.

4.6.5 If a FAILURE occurs for any reason, NEKTAR AL shall have the option to elect to transfer manufacturing of SELECTED REAGENT back to NEKTAR AL at such time as it is ready to recommence manufacturing (i.e., NEKTAR AL has corrected any manufacturing issues or force majeure has ceased), in which event COMPANY shall no longer purchase any SELECTED REAGENT from the CONTRACT MANUFACTURER.

4.6.6 COMPANY’s sole and exclusive remedy against NEKTAR AL, and the entire liability of NEKTAR AL, for any FAILURE shall be limited to the remedies described in this Section 4.6 above, and a FAILURE shall not be deemed a breach of this AGREEMENT by NEKTAR AL; in each case unless such FAILURE is intentional or willful.

-21-

5. SPECIFICATIONS and Manufacturing Warranty for SELECTED REAGENT

5.1 Specifications. The SPECIFICATIONS for SELECTED REAGENT to be supplied pursuant to Article 4 will be set forth in the QUALITY AGREEMENT. Any modifications of the SPECIFICATIONS shall require prior written approval of COMPANY and NEKTAR AL, not to be unreasonably withheld or delayed. COMPANY shall reimburse NEKTAR AL for its reasonable costs associated with implementing any modifications to the SPECIFICATIONS, including without limitation any increases in NEKTAR AL’s manufacturing costs, in accordance with terms to be mutually agreed.

5.2 Warranty. NEKTAR AL warrants that: (a) SELECTED REAGENT shall be manufactured in compliance with (i) the quality standards and testing methods of NEKTAR AL for such SELECTED REAGENT and (ii) the then-current International Conference on Harmonization Q7A Good Manufacturing Practice Guide as it applies to critical raw materials for use in the manufacture of human pharmaceuticals (“ICH Q7A”) and all other equivalent governmental requirements relevant to the classification of such reagent as a critical raw material, in the countries of the TERRITORY in which SELECTED PRODUCTS are sold or intended to be sold; (b) each shipment of SELECTED REAGENT shall, upon delivery pursuant to Section 8.3, be in conformity with the applicable SPECIFICATIONS; (c) the SELECTED REAGENT shall not be adulterated or misbranded by NEKTAR AL within the meaning of the Federal Food, Drug and Cosmetic Act; and (d) the SELECTED REAGENT shall, upon release for delivery pursuant to Section 8.3, have at least six (6) months of remaining shelf life before it expires. Notwithstanding anything to the contrary in this AGREEMENT, NEKTAR AL’s sole liability and COMPANY’s sole and exclusive remedy for breach of the foregoing warranty shall be limited to the actions and procedures required in Articles 4 and 6.

5.3 No Guarantee. COMPANY acknowledges that NEKTAR AL cannot guarantee the safety, non-toxicity, fitness or efficacy of SELECTED REAGENT or SELECTED PRODUCT, and COMPANY accepts any and all risk resulting from its use of SELECTED REAGENT or SELECTED PRODUCT.

6. Quality and Complaints

6.1 Analysis. Each shipment of SELECTED REAGENT shall be accompanied by a certificate of analysis (“COA”) describing all current requirements of the SPECIFICATIONS and such other information as may be agreed upon by the PARTIES in writing, provided that in no event shall such COA contain less information than is otherwise reasonably necessary to comply with requirements of the FDA or other applicable regulatory authorities. Within thirty (30) days after arrival of a shipment of SELECTED REAGENT at COMPANY or COMPANY’s

-22-

designated site, COMPANY shall analyze such SELECTED REAGENT using methods approved in writing by both PARTIES according to the test procedures set forth in the QUALITY AGREEMENT.

6.2 Complaints.

COMPANY shall notify NEKTAR AL in writing if COMPANY believes that a shipment of SELECTED REAGENT does not comply with the warranty in Section 5.2 within thirty (30) days after COMPANY’s receipt of the relevant shipment of SELECTED REAGENT, and shall include full details of the basis for COMPANY’s assertion of such noncompliance (including supporting data) for purposes of consideration and verification by NEKTAR AL. If no such written notice of noncompliance is received by NEKTAR AL within the above thirty (30) day period, COMPANY shall be deemed to have accepted the applicable shipment of SELECTED REAGENT, which shall thereafter conclusively be presumed to be without defect and to meet all applicable SPECIFICATIONS and warranties hereunder.

6.3 Complaints Procedure. If NEKTAR AL receives a notice of noncompliance under Section 6.2, the following procedures shall apply:

6.3.1 If NEKTAR AL accepts the details submitted by COMPANY as to the non-compliance of a shipment of SELECTED REAGENT, NEKTAR AL shall supply COMPANY an amount of such SELECTED REAGENT equal to that which was allegedly noncompliant from the relevant shipment at no additional cost to COMPANY, within a timeframe that has been mutually agreed to by both PARTIES in writing (but in no event later than ninety (90) days provided NEKTAR AL has exercised reasonable commercial efforts to supply such replacement quantity of SELECTED REAGENT within a shorter timeframe), such acceptance not to be unreasonably withheld or delayed. COMPANY shall return to NEKTAR AL any SELECTED REAGENT that NEKTAR AL accepts as noncompliant.

6.3.2 If NEKTAR AL does not accept the details submitted by COMPANY as to the non-compliance of a shipment of SELECTED REAGENT, then within thirty (30) days from the date on which the details of COMPANY’s complaint are received by NEKTAR AL, NEKTAR AL shall appoint (i) an independent scientific and technical expert reasonably acceptable to COMPANY to review the details supporting COMPANY’s assertion of non-compliance with Sections 5.2(a), (c) or (d), or (ii) an independent laboratory reasonably acceptable to COMPANY for any assertion of non-compliance with Section 5.2(b). COMPANY shall not unreasonably withhold or delay acceptance of the independent scientific and technical expert or independent laboratory appointed by NEKTAR AL. The findings of such expert or laboratory, as the case may be, shall be final and conclusively binding on the PARTIES as to whether such SELECTED

-23-

REAGENT complies with the warranty in Section 5.2. If the expert or laboratory determines that such SELECTED REAGENT is noncompliant, then all the fees of the expert or the laboratory shall be paid by NEKTAR AL, and COMPANY shall have no obligation to pay for the quantities of noncompliant SELECTED REAGENT, but shall be responsible for payment of replacement quantities that conform to the applicable warranty set forth in Section 5.2 within thirty (30) days after the date of invoice for such replacement shipment. On the other hand, if the expert or laboratory confirms that such SELECTED REAGENT did comply with the applicable requirements of Section 5.2, then all of the fees of the laboratory or the expert shall be paid by COMPANY. COMPANY shall promptly pay for any replacement quantities shipped by NEKTAR AL in addition to the original quantities shipped, and COMPANY shall be considered to have finally and completely accepted such allegedly noncompliant shipment of SELECTED REAGENT.

6.4 Fees for Manufacturing and Supply of SELECTED REAGENT.

6.4.1 As of the EFFECTIVE DATE, the price per gram of SELECTED REAGENT is as shown on Schedule V (the “PURCHASE PRICE”). During the TERM hereof, COMPANY shall pay to NEKTAR AL the PURCHASE PRICE for the supply of SELECTED REAGENT, which PURCHASE PRICE shall be increased on an annual basis as follows: on January 1, 2008 and on each successive anniversary of January 1 during the TERM, the PURCHASE PRICE will be increased by adding to the PURCHASE PRICE a number obtained by multiplying the then-current PURCHASE PRICE by a fraction, the numerator of which is the United States Department of Labor Producer Price Index for Chemical Manufacturing Series ID: PCU325—325— (“PK) in the month and year of the EFFECTIVE DATE subtracted from the PPI in the month three (3) months prior to the respective adjustment date and the denominator of which is the PPI in the month and year of the EFFECTIVE DATE. If the numerator reflects an increase, the number will be added to the PURCHASE PRICE. The PURCHASE PRICE may also be increased if and as the following items occur: (a) changes to the SPECIFICATIONS requested by COMPANY and which are agreed to by NEKTAR AL; (b) change in the SELECTED REAGENT manufacturing process as requested by COMPANY and which is agreed to by NEKTAR AL; and/or (c) change to the SELECTED REAGENT as required by LAW. In the case of the foregoing clauses (a) and (b), the increase in PURCHASE PRICE shall be mutually agreed by the PARTIES prior to the implementation of any changes to the SPECIFICATIONS or manufacturing process.

6.4.2 In addition, NEKTAR agrees to provide, and COMPANY shall pay to NEKTAR AL fees for providing, services to COMPANY at NEKTAR AL’s then-current rates, which rates shall be reasonable and shall be provided to COMPANY prior to NEKTAR AL commencing any such

-24-

services. In general, such services may include providing assistance with regulatory requirements, as well as covering NEKTAR AL’s performance of those activities reasonably deemed necessary by NEKTAR AL for the development, scale-up and validation of the manufacture of SELECTED REAGENT, provided in each case that COMPANY has approved such services in advance in writing by means of the issuance to NEKTAR AL of a purchase order authorizing the performance of such services. Specifically, such fees shall cover, among other things:

(a) improvements to and expansion of facilities, analytical method development, analytical method validation, cleaning method validation, process validation, reprocessing and supporting documentation including, but not limited to, the preparation, filing and maintenance of Drug Master Files and other regulatory filings;

(b) NEKTAR AL’s generating and providing information or performing work pursuant to any governmental or regulatory agency requests for information or work (including any testing) regarding SELECTED REAGENT or its manufacturing process;

(c) installation, qualification and validation needed for SELECTED REAGENT, including scale-up;

(d) changes to SPECIFICATIONS; and

(e) other services requested by COMPANY from time to time during the TERM.

COMPANY shall also reimburse NEKTAR AL for NEKTAR AL’s reasonable expenses incurred in connection with (i) the purchase of capital equipment in connection with the activities described in Subsections 6.4.2 (a)-(e) above (provided such capital equipment purchases are pre-approved in writing by COMPANY), and (ii) travel at COMPANY’s request, such reimbursement to be made within thirty (30) days after the date of NEKTAR AL’s invoice therefor.

7. Milestones; Royalty Payments; Royalty Reports

7.1 Milestone Payments. COMPANY shall pay to NEKTAR AL non-creditable, non-refundable milestone payments in accordance with and on the dates provided in Schedule II hereto for SELECTED PRODUCT. Such milestone payments shall be in addition to any royalty or other payments due under this AGREEMENT. If for whatever reason, a particular milestone event for which a milestone payment is due is not achieved then in such case, the milestone payment that NEKTAR AL would have received upon the occurrence of such milestone event for the SELECTED PRODUCT, had the particular milestone event been achieved, shall be paid on the occurrence of the next milestone event for which a milestone payment is due, which payment shall be paid in addition to, and not instead of, the milestone payment that is to be paid to NEKTAR AL upon the occurrence of the next milestone event.

-25-

7.2 Royalties. During the ROYALTY TERM, COMPANY shall pay NEKTAR AL non-refundable and non-creditable royalties in an amount equal to [*] (such percentages, the “ROYALTY RATE”). Royalties shall be incremental, such that if NET SALES of SELECTED PRODUCT exceed [*] in any year (on a calendar year basis), then COMPANY shall pay NEKTAR AL a [*] royalty on the first [*] of the annual aggregate NET SALES of SELECTED PRODUCT for such year, and a [*] royalty on the amount of the annual aggregate NET SALES of SELECTED PRODUCT for such year that exceeds [*]. The applicable ROYALTY RATE shall be reduced by [*] for NET SALES of SELECTED PRODUCT in each country where there is no VALID PATENT CLAIM covering the manufacture, use, import, offer for sale or sale of SELECTED REAGENT or SELECTED PRODUCT. In addition, if the sublicense granted under Section 2.2 is terminated by ENZON as a result of the breach or default by NEKTAR AL of the CROSS-LICENSE AGREEMENT, and COMPANY or its SUBLICENSEE is required to pay ENZON, or an AFFILIATE of ENZON, amounts with respect to SELECTED PRODUCT in consideration for a license to the ENZON PATENTS listed on Schedule VII, then the ROYALTY RATES applicable to NET SALES of SELECTED PRODUCT in countries in which the manufacture, use, importation, offer for sale or sale of the SELECTED PRODUCT is covered by a VALID ENZON PATENT CLAIM shall be reduced by [*] for so long as the manufacture, use, importation, offer for sale or sale of the SELECTED PRODUCT in such country continues to be covered by a VALID ENZON PATENT CLAIM.

7.2.1 COMBINATION PRODUCTS. In the event that SELECTED PRODUCT is sold for a single combined price with another product for which no royalty would be due hereunder if sold separately, NET SALES for purposes of calculating the amounts due under Section 7.2 shall be calculated by multiplying the NET SALES of the combination product by the fraction A / (A + B), where “A” is the average gross selling price of SELECTED PRODUCT during the previous calendar quarter and “B” is the average gross selling price of the other product during the previous calendar quarter. In the event that separate sales of SELECTED PRODUCT and the additional product were not made during the previous calendar quarter, NET SALES shall be reasonably allocated in good faith between SELECTED PRODUCT and such other product based upon the relative market values thereof. Notwithstanding the foregoing, if SELECTED PRODUCT is sold for a single combined price with a product which serves as an antidote for the SELECTED PRODUCT (i.e., an oligonucleotide that binds to the SELECTED PRODUCT) (the “COMBINATION PRODUCT”), the NET SALES of such SELECTED PRODUCT for purposes of calculating the amounts due under Section 7.2 shall not be less than fifty percent (50%) of the NET SALES of the COMBINATION PRODUCT.

7.2.2 In the event that both SELECTED PRODUCT and a product comprising an oligonucleotide that binds to the SELECTED PRODUCT and serves as an antidote for the SELECTED PRODUCT (an “SELECTED PRODUCT ANTIDOTE”) are sold separately, the aggregate annual NET SALES of the SELECTED PRODUCT sold separately shall not, for purposes of calculating the amounts due under Section 7.2, be less than fifty percent (50%) of the combined annual aggregate NET SALES of the SELECTED PRODUCT ANTIDOTE sold separately and the SELECTED PRODUCT sold separately. In the event that the actual aggregate annual NET SALES of the SELECTED PRODUCT sold separately is less than fifty percent (50%) of the actual combined annual aggregate NET SALES of the SELECTED PRODUCT ANTIDOTE sold separately and the SELECTED PRODUCT sold separately, the aggregate annual NET SALES of the SELECTED PRODUCT sold separately in the applicable calendar year shall be deemed to be an amount equal to fifty percent (50%) of the actual combined annual aggregate NET SALES of the SELECTED PRODUCT ANTIDOTE sold separately and the SELECTED PRODUCT sold separately for purposes of calculating the amounts due under Section 7.2. For example, if, in a particular calendar year, the aggregate NET SALES of SELECTED PRODUCT ANTIDOTE sold separately is six hundred fifty million DOLLARS ($650,000,000) and the aggregate NET SALES of SELECTED PRODUCT sold separately is five hundred million DOLLARS ($500,000,000), then, for purposes of calculating the amounts due under Section 7.2, the aggregate NET SALES of SELECTED PRODUCT for such year shall be deemed to be five hundred seventy-five million DOLLARS ($575,000,000). Because the combined annual aggregate NET SALES of SELECTED PRODUCT and SELECTED PRODUCT ANTIDOTE sold separately in a calendar year would not be known in advance, COMPANY would, if applicable, make a lump sum payment to NEKTAR AL for the amount of any increase in royalties payable under Section 7.2 based on the application of this Section 7.2.2 within thirty (30) days after the end of the applicable calendar year.

7.2.3 If COMPANY, its AFFILIATES or its SUBLICENSEES are required to pay royalties to any THIRD PARTY because the manufacture, use, import, offer for sale or sale of SELECTED PRODUCT infringes any PATENT of such THIRD PARTY in any country of the TERRITORY (but only with respect to the composition of matter or the method of making the SELECTED REAGENT incorporated in SELECTED PRODUCT) then in such event, COMPANY may deduct from royalties thereafter due to NEKTAR AL with respect to NET SALES of SELECTED PRODUCT in such country up to [*] of the royalties paid to such THIRD PARTY, subject to the limitation in the immediately following sentence. In no event shall the royalties due on the NET SALES of SELECTED PRODUCT on account of any reduction pursuant to this Section 7.2.3 be thereby reduced by more than [*] of the royalties which otherwise would have been due under Section 7.2 on the NET SALES of such SELECTED PRODUCT.

-27-

7.3 SUBLICENSEE Royalty Assumption. Upon COMPANY’s election in connection with the granting of a sublicense in accordance with Section 2.4.1, COMPANY may arrange for the applicable SUBLICENSEE to agree in writing with NEKTAR AL that such SUBLICENSEE shall assume, and pay directly to NEKTAR AL, COMPANY’s royalty obligations pursuant to Sections 7.2, 7.5, 8.2 (solely as they relate to royalties), 8.4 (solely as they relate to royalties and royalty reports), 8.5, 8.6 and 15.6.2(d) (solely as they relate to royalties) with respect to such SUBLICENSEE’s NET SALES of SELECTED PRODUCT, provided, however, that (i) COMPANY shall be liable for any failure by such SUBLICENSEE to make timely payment of such royalties when due hereunder while this AGREEMENT remains in effect and (ii) COMPANY may not exercise the foregoing right with respect to more than two (2) sublicenses.

7.4 PARTNERING UPFRONT REVENUES. For each PARTNERING TRANSACTION that COMPANY enters into during the TERM, COMPANY shall pay to NEKTAR AL an amount equal to [*] of the PARTNERING UPFRONT REVENUES for such PARTNERING TRANSACTION. All payments made hereunder shall be non-refundable and non-creditable. COMPANY covenants to act in good faith with respect to the structuring of payments of PARTNERING UPFRONT REVENUES; provided that any payment received more than six (6) months after the effective date of the PARTNERING TRANSACTION, and any payment that is contingent upon the occurrence of events after such date that are not certain to occur, shall conclusively be presumed not to be PARTNERING UPFRONT REVENUES.

7.5 Reports, Exchange Rates. COMPANY shall notify NEKTAR AL in writing promptly upon the FIRST COMMERCIAL SALE of SELECTED PRODUCT in each country. Commencing upon the FIRST COMMERCIAL SALE of SELECTED PRODUCT, COMPANY shall furnish to NEKTAR AL a quarterly written report showing, on a country-by-country basis, according to the volume of units of SELECTED PRODUCT sold in each such country (by SKU) during the reporting period: (a) the gross invoiced sales of SELECTED PRODUCT sold in each country during the reporting period, and the amounts deducted therefrom to determine NET SALES from such gross invoiced sales (including with specificity, if applicable, the customary trade and quantity discounts actually allowed and taken); the allowances actually given for returned SELECTED PRODUCT; the freight and insurance, if separately identified on the invoice; the government-mandated and other rebates customary in the industry; and the value added tax, sales, use or turnover taxes, excise taxes and customs duties included in the invoiced price); (b) the royalties payable in DOLLARS, if any, which shall have accrued hereunder based upon the NET SALES of SELECTED PRODUCT; (c) the withholding taxes, if any, required by LAW to be deducted in respect of such sales; (d) the date of the FIRST COMMERCIAL SALE of SELECTED PRODUCT in each country during the reporting period; and (e) the amount of

-28-

PARTNERING UPFRONT REVENUE payable by COMPANY during the reporting period, broken down by PARTNERING TRANSACTION. In the event that SELECTED PRODUCT ANTIDOTE of the SELECTED PRODUCT is sold separately or any COMBINATION PRODUCTS are sold in a particular calendar quarter, COMPANY shall also include in each quarterly written report such information necessary for NEKTAR AL to verify the calculation of the amount of royalties due by COMPANY to NEKTAR AL under Section 7.2. With respect to sales of SELECTED PRODUCT invoiced in DOLLARS, the gross invoiced sales, NET SALES, and royalties payable shall be expressed in the report in DOLLARS. With respect to sales of SELECTED PRODUCT invoiced in a currency other than DOLLARS, the gross invoiced sales, NET SALES and royalties payable shall be expressed in the report provided hereunder in the currency of the sale as well as in the DOLLAR equivalent of the royalty payable and the exchange rate used in determining the amount of DOLLARS. The DOLLAR equivalent shall be calculated using the average exchange rate (local currency per DOLLAR) published in The Wall Street Journal, Western Edition, under the heading “Currency Trading,” on the last business day of each month during the applicable calendar quarter. Reports shall be due hereunder on the sixtieth (60th) day following the close of each quarter.

8. Records; Audits; Shipment Terms; Payment Terms

8.1 Records. COMPANY and its SUBLICENSEES shall keep complete and accurate records in sufficient detail to make the reports required hereunder, to confirm their respective compliance with the provisions of Section 4.1, to properly reflect all gross sales and NET SALES of all PRODUCT and to verify the determination of all amounts payable hereunder. Without limiting the foregoing, COMPANY shall include in each sublicense granted by it pursuant to this AGREEMENT a provision requiring the SUBLICENSEE to make reports to COMPANY consistent with those COMPANY is required to provide hereunder, to keep and maintain records of sales made and deductions taken in calculating royalties due to NEKTAR AL with respect to such sublicense, and to grant access to such records by NEKTAR AL’s independent accountant pursuant to Section 8.2 below to the same extent required of COMPANY under this AGREEMENT. Alternatively, to the extent that COMPANY does not obtain the right for NEKTAR AL (or NEKTAR AL’S independent accountant) the right to audit its SUBLICENSEE’S books and records hereunder, COMPANY shall obtain for itself such right and, at the request of NEKTAR AL, COMPANY shall exercise such audit right with respect to SUBLICENSEES and provide the results of such audit for inspection by NEKTAR AL pursuant to Section 8.2 below. Any such audit shall be treated the same as an audit by NEKTAR AL of COMPANY for purposes of 8.2 below (e.g., with respect to the payment of costs therefor).

8.2 Audits. Upon the written request of NEKTAR AL, COMPANY shall permit an independent certified public accounting firm of recognized national standing in the United States, selected by NEKTAR AL and reasonably acceptable to COMPANY, at NEKTAR AL’s expense, to have access during normal business

-29-

hours to such of the records of COMPANY as may be reasonably necessary to verify (I) COMPANY’s compliance with the purchase requirements of Section 4.1, and (ii) the accuracy of any amounts reported, actually paid or payable under this AGREEMENT for any year ending not more than twenty-four (24) months prior to the date of such request. Any such verifications shall be carried out under conditions of confidentiality. If such accounting firm establishes that additional royalty amounts were owed to NEKTAR AL during such period, COMPANY shall pay such additional royalties at the rate of twelve percent (12%) per annum, compounded monthly, or the maximum rate allowed under LAW, whichever is less, from the date such royalty amounts were payable) within thirty (30) days of the date NEKTAR AL delivers to COMPANY such accounting firm’s written report so concluding. The fees charged by such accounting firm shall be paid by NEKTAR AL; provided however, that if the audit discloses that the royalties payable by COMPANY for the audited period are more than one hundred five percent (105%) of the royalties actually paid for such period, or if the audit discloses that COMPANY has not complied with Section 4.1, then COMPANY shall pay the reasonable fees and expenses charged by such accounting firm. Upon the expiration of twenty-four (24) months following the end of any calendar year, the calculation of royalties payable with respect to such calendar year shall be binding and conclusive upon NEKTAR AL and COMPANY and its SUBLICENSEES.

8.3 Delivery and Shipment; Title and Risk of Loss. NEKTAR AL shall deliver all SELECTED REAGENT to COMPANY or its designee, and title to and risk of loss of each quantity of SELECTED REAGENT so delivered shall pass to COMPANY Ex Works (lncoterms 2000) NEKTAR AL’s manufacturing or storage facilities. Such delivery shall constitute a shipment hereunder.

All shipments shall be addressed to the destination specified by COMPANY and set forth in the relevant purchase order.

8.4 Invoicing; Payment Terms. NEKTAR AL shall send invoices to COMPANY for any SELECTED REAGENT shipped to COMPANY no earlier than the date of shipment pursuant to Section 8.3 above.

Royalties shown to have accrued to NEKTAR AL as set forth in each royalty report to be provided under Section 7.5 shall be due and payable on or before the date such royalty report is due. Payments due under Section 7.4 shall be due and payable ten (10) days after COMPANY’s or its AFFILIATE’s receipt of the applicable PARTNERING UPFRONT REVENUES. Any and all amounts past due under this AGREEMENT shall bear interest at the rate of twelve percent (12%) per annum, compounded monthly, or the maximum rate allowed under LAW, whichever is less.

-30-

8.5 Payment Method. Except as otherwise provided for herein, all payments by COMPANY under this AGREEMENT shall be paid in DOLLARS, and all such payments shall be made by bank wire transfer in immediately available funds to such account as NEKTAR AL shall designate before such payment is due. With respect to any royalty payments due to NEKTAR AL hereunder, upon the election of NEKTAR AL made in writing not less than thirty (30) days’ prior to a particular payment date, COMPANY shall pay all royalties owing to NEKTAR AL hereunder on such payment date in the currency in which such royalties accrued, without conversion into DOLLARS. If at any time legal restrictions prevent the prompt remittance of part or all royalties due with respect to sales of SELECTED PRODUCT in any country where SELECTED PRODUCT is sold, payment shall be made through such lawful means or methods as NEKTAR AL shall reasonably determine.

8.6 Taxes. All amounts due hereunder shall be paid without deduction for withholding for any taxes or similar governmental charges imposed by a jurisdiction other than the United States so long as NEKTAR AL is resident, and accepts such amounts paid to a bank account located, in the United States, and COMPANY shall provide NEKTAR AL evidence of its payment of any such withholdings that may be required; provided that to the extent NEKTAR AL can use any such withholdings paid by COMPANY as a credit to reduce NEKTAR AL’s United States tax liability, NEKTAR AL shall repay to COMPANY the amount of such reduction. in addition, the PARTIES shall cooperate to reduce and/or eliminate the need for such withholding for taxes.

Each PARTY shall promptly disclose in writing to the other all INVENTIONS arising from the joint or separate activities (including any INVENTIONS first made, conceived or first reduced to practice as a result of performing such activities) of the PARTIES or, to the extent such PARTY has the right to do so, their agents, independent contractors (including CMOs) or, in the case of COMPANY, SUBLICENSEES, in connection with the performance of their obligations or activities under this AGREEMENT (including in the manufacture of SELECTED PRODUCT); provided, however, that NEKTAR AL shall not be obligated to disclose under this Section 13.2 a SOLE INVENTION to the extent such SOLE INVENTION falls within the scope of NEKTAR AL CORE TECHNOLOGY (and is not necessary for COMPANY to exercise the license granted by NEKTAR AL hereunder) and that COMPANY shall not be obligated to disclose under this Section 13.2 a SOLE INVENTION to the extent such SOLE INVENTION falls within the scope of COMPANY CORE TECHNOLOGY. INVENTION disclosures made by a PARTY pursuant to this Section 13.2 shall be in a reasonable summary format, and each PARTY agrees to provide additional, detailed information underlying such summary disclosures following the request of the other PARTY.

13.3 Ownership of INVENTIONS. Except as otherwise set forth in Sections 13.4 or 13.6, all INVENTIONS made solely by employees, agents, independent contractors (including CMOs) or, in the case of COMPANY, SUBLICENSEES of a PARTY during the course and performance of this AGREEMENT (including in the manufacture of SELECTED PRODUCT) (each, to the extent owned by a PARTY, a “SOLE INVENTION”) shall be the exclusive property of such PARTY. Except as otherwise set forth in Sections 13.4 or 13.6, if employees,

-39-

agents, independent contractors (including CMOs) or, in the case of COMPANY, SUBLICENSEES of each of NEKTAR AL and COMPANY jointly develop any INVENTION during the course and in the performance of activities conducted in connection with this AGREEMENT (including in the manufacture of SELECTED PRODUCT) (each, a “JOINT INVENTION”), COMPANY and NEKTAR AL shall each own an undivided one-half (1/2) interest in and to such JOINT INVENTION, and shall have the right to freely exploit and grant licenses under any such JOINT INVENTION and any PATENT claiming such JOINT INVENTION without consent of or a duty of accounting to the other PARTY, and each PARTY hereby waives any right to require such consent under applicable LAWS, and if such waiver is not effective, agrees to provide such consent. For the avoidance of doubt, the determination as to whether an INVENTION has been “solely” or “jointly” made shall be based upon whether employees, agents, independent contractors (including CMOs) or, in the case of COMPANY, SUBLICENSEES of a PARTY would be or are properly named as an inventor on a corresponding PATENT APPLICATION under United States inventorship LAWS.

13.4 NEKTAR AL CORE TECHNOLOGY INVENTIONS. Any and all right, title and interest in and to all SOLE INVENTIONS and JOINT INVENTIONS which fall within the scope of NEKTAR AL CORE TECHNOLOGY shall belong solely to NEKTAR AL (“NEKTAR AL CORE TECHNOLOGY INVENTIONS”). COMPANY hereby agrees to and hereby does, and shall, without additional consideration transfer and assign to NEKTAR AL all of its right, title and interest in and to such NEKTAR AL CORE TECHNOLOGY INVENTIONS and all intellectual property rights therein including enforcement rights, and shall require its employees, and to the extent COMPANY obtains such rights for itself, shall require its agents, independent contractors (including CMOs) and, in the case of COMPANY, SUBLICENSEES, to so assign their right, title and interest therein to NEKTAR AL. NEKTAR AL shall be responsible, at its sole expense and discretion, and with the cooperation of COMPANY, for the filing, prosecution and maintenance of foreign and domestic PATENT APPLICATIONS and PATENTS issuing therefrom covering such NEKTAR AL CORE TECHNOLOGY INVENTIONS, provided, however, that, with respect to any NEKTAR AL CORE TECHNOLOGY INVENTIONS that are SOLE INVENTIONS of COMPANY or JOINT INVENTIONS, NEKTAR AL shall (i) keep COMPANY reasonably informed as to the filing, prosecution and maintenance of such PATENT APPLICATIONS and PATENTS, (ii) furnish to COMPANY copies of documents relevant to any such filing, prosecution and maintenance, and (iii) allow COMPANY reasonable opportunity to comment on documents filed with any patent office which would affect such PATENT APPLICATIONS and PATENTS. All NEKTAR AL CORE TECHNOLOGY INVENTIONS shall be deemed to be included in the NEKTAR AL LICENSED TECHNOLOGY and subject to the license granted to COMPANY pursuant to Section 2.1. Notwithstanding anything to the contrary herein, during the TERM, COMPANY shall use COMMERCIALLY REASONABLE EFFORTS to obligate any and all agents, independent contractors (including CMOs), and

-40-

SUBLICENSEES to transfer and assign to COMPANY all of their right, title and interest in and to INVENTIONS and all intellectual property rights therein, including enforcement rights. If COMPANY is unable to do so, COMPANY shall notify NEKTAR AL prior to having any such PERSON perform any activities under this AGREEMENT including manufacture of SELECTED PRODUCT.

13.5 GRANT-BACK INVENTIONS. NEKTAR AL shall grant, and hereby grants, to COMPANY a non-exclusive, royalty-free, fully-paid up, worldwide license, with right to sublicense, under all APTAMER INVENTIONS AND DATA (including all intellectual property rights therein) that are included in NEKTAR AL CORE TECHNOLOGY, which are invented either solely or jointly by employees, agents or contractors of COMPANY to make, use, sell, offer to sell, import and otherwise commercialize the SELECTED PRODUCT and other products which COMPANY is currently developing, or may develop in the future, either alone or in collaboration with AFFILIATES, SUBLICENSEES OR THIRD PARTIES, provided that this license shall be sublicensable to THIRD PARTIES only to the extent reasonably necessary to make, use, import, export, sell, offer to sell and otherwise exploit products developed in whole or in part by COMPANY.

13.6 COMPANY CORE TECHNOLOGY INVENTIONS. Any and all right, title and interest in and to all SOLE INVENTIONS and JOINT INVENTIONS which fall within the scope of COMPANY CORE TECHNOLOGY shall belong solely to COMPANY (“COMPANY CORE TECHNOLOGY INVENTIONS”). NEKTAR AL hereby agrees to and hereby does, and shall, without additional consideration assign to COMPANY all of its right, title and interest in and to any COMPANY CORE TECHNOLOGY INVENTIONS and all intellectual property rights therein including enforcement rights, and shall require its employees, agents or independent contractors to so assign their right, title and interest therein to COMPANY. COMPANY shall be responsible, at its sole expense and discretion, and with the cooperation of NEKTAR AL if requested by COMPANY, for the filing, prosecution and maintenance of foreign and domestic PATENT APPLICATIONS and PATENTS issuing therefrom covering such COMPANY CORE TECHNOLOGY INVENTIONS.

13.7 Individual PATENT Filings. Each PARTY shall have the sole discretion and right to prepare, file, prosecute, maintain and defend PATENT APPLICATIONS and PATENTS issuing therefrom for INVENTIONS it solely owns under this AGREEMENT, and shall be responsible for related interference proceedings. During the TERM, each PARTY shall confer with the other PARTY, and make every reasonable effort to adopt the other PARTY’s suggestions regarding the prosecution of such PATENT APPLICATIONS, and shall copy the other PARTY on any official actions and submissions regarding the filing and prosecution of such PATENT APPLICATIONS. Costs incurred with respect to PATENT APPLICATIONS shall be borne by the PARTY with the right to prosecute each such PATENT APPLICATION.

-41-

13.8 Joint PATENT Filings. With respect to all PATENT APPLICATIONS on JOINT INVENTIONS that are jointly owned by the PARTIES (i.e., JOINT INVENTIONS that have not been assigned nor are assignable to the other PARTY pursuant to Sections 13.4 and 13.6) (the “JOINT PATENT APPLICATIONS”), the PARTIES shall determine which PARTY shall be responsible for filing, prosecuting and maintaining PATENT APPLICATIONS and PATENTS issuing therefrom (the “JOINT PATENTS”) on behalf of both PARTIES (such PARTY, the “RESPONSIBLE PARTY”) based on a good faith determination of the relative contributions of the PARTIES to the INVENTION and the relative interests of the PARTIES in the INVENTION. At least twenty (20) days prior to the contemplated filing of such PATENT APPLICATION, the RESPONSIBLE PARTY shall submit a substantially completed draft of the JOINT PATENT APPLICATION to the other PARTY for its approval, which shall not be unreasonably withheld or delayed. Except as set forth below, the PARTIES shall share equally the costs of the preparation, filing, prosecution and maintenance of all JOINT PATENT APPLICATIONS and JOINT PATENTS. If either PARTY elects not to pay its portion of any shared costs for a JOINT PATENT APPLICATION or JOINT PATENT, the other PARTY may proceed with such JOINT PATENT APPLICATION or JOINT PATENT in its own name and at its sole expense, in which case the PARTY electing not to pay its share of costs hereby agrees to transfer and assign and shall transfer and assign its entire right, title and interest in and to such JOINT PATENT APPLICATION or JOINT PATENT to the other PARTY and such INVENTION shall be treated as a SOLE INVENTION of the assignee for the purposes of Sections 13.3 and 13.7.

13.9 Further Actions. Each PARTY shall cooperate with the other PARTY to execute all documents and take all reasonable actions to effect the intent of this Article 13.

14. Infringement

14.1.2 Litigation Unrelated to SELECTED REAGENT. Except to the limited extent provided for in Section 14.1.3, COMPANY shall defend, indemnify and hold harmless each NEKTAR AL INDEMNITEE from and against all losses, liabilities, damages, costs and expenses (including reasonable attorney’s fees and costs of investigation and litigation, regardless of outcome) resulting from any CLAIM that the development, manufacture, use, import, offer for sale or sale of SELECTED PRODUCT infringes a THIRD PARTY PATENT or misappropriates THIRD PARTY KNOW¬HOW, and the provisions of Sections 12.1.2 and 12.3 shall apply

-42-

with respect to any such CLAIM to the same extent as though it were a CLAIM for which COMPANY has an obligation to defend, indemnify and defend NEKTAR AL under Section 12.1.2. In the event of a conflict between the provisions of Article 13 and this Section 14.1.2, the provisions of this Section 14.1.2 shall apply.

14.1.3 COMPANY’s obligations under Section 14.1.2 (and 12.1.2) shall not apply to the extent that any infringement of a THIRD PARTY PATENT results solely from the composition of matter or the manufacture of SELECTED REAGENT.

14.2 Infringement By THIRD PARTIES.

14.2.1 Notice of Infringement. If any VALID PATENT CLAIM or any PATENT owned, CONTROLLED or licensed by COMPANY covering SELECTED PRODUCT is infringed by a THIRD PARTY, or any KNOW¬HOW utilized in the manufacture, use, import, offer for sale or sale of SELECTED REAGENT or SELECTED PRODUCT is misappropriated by a THIRD PARTY, the PARTY first having knowledge of such infringement or misappropriation shall promptly notify the other PARTY in writing. The notice shall set forth the facts of such infringement or misappropriation in reasonable detail.

14.2.2 Prosecution of Actions Related to NEKTAR AL PATENT RIGHTS.

(a) NEKTAR AL shall have the primary right, but not the obligation, to institute, prosecute and control any action or proceeding with respect to any infringement of a VALID NEKTAR AL PATENT CLAIM or misappropriation of NEKTAR AL KNOW-HOW as described in Section 14.2.1 by reason of a THIRD PARTY’s manufacture, use, import, offer for sale or sale of SELECTED REAGENT or SELECTED PRODUCT, using counsel of its own choice at its own expense. COMPANY shall cooperate with NEKTAR AL at NEKTAR AL’s request and expense in the prosecution of such action or proceeding. If NEKTAR AL determines that COMPANY is an indispensable PARTY to the action, COMPANY hereby consents to be joined. In such event, COMPANY shall have the right to be represented in that action by its own counsel at its own expense.

(b) If NEKTAR AL fails to bring an action or proceeding within a period of sixty (60) days after receiving written notice from COMPANY or otherwise having knowledge of such infringement or misappropriation by reason of a THIRD PARTY’s manufacture,

-43-

use, import, offer for sale or sale of products incorporating SELECTED PRODUCT, COMPANY shall have the right to bring and control any such action using counsel of its own choice at its own expense. If COMPANY determines that NEKTAR AL is an indispensable PARTY to the action, NEKTAR AL hereby consents to be joined. In such event, NEKTAR AL shall have the right to be represented in such action by its own counsel at its own expense. No settlement, consent judgment or other voluntary final disposition of a suit under this Section 14.2.2 may be entered into without the joint consent of COMPANY and NEKTAR AL (which consent shall not be withheld or delayed unreasonably), provided the foregoing shall not limit the COMPANY’S right to grant sublicenses under Article 2 above.

(c) Awards. If either PARTY brings an action for infringement or misappropriation by a THIRD PARTY under this Section 14.2.2, any damages or other monetary awards or payments in settlement recovered by such PARTY with respect to such infringement or misappropriation shall be applied first to defray the costs and expenses incurred by both PARTIES in the action. Any remainder of the net amount recovered (after payment of amounts owed to others in respect of such recovery) shall be shared by the PARTIES as follows: seventy-five percent (75%) of such remainder shall be retained by the PARTY controlling such action and twenty-five percent (25%) of such remainder shall be retained by the other PARTY.

14.2.3 Prosecution of Actions Related to SELECTED PRODUCT.

(a) Except as otherwise provided in Section 14.2.2 and except with respect to infringement by a THIRD PARTY of a VALID ENZON PATENT CLAIM, COMPANY shall have the right, but not the obligation, to carry out actions against THIRD PARTIES arising from such THIRD PARTIES’ manufacture, use, import, offer for sale or sale of SELECTED PRODUCT.

(b) Awards. If COMPANY brings an action for infringement or misappropriation by a THIRD PARTY under this Section 14.2.3 of a PATENT or KNOW-HOW owned or licensed by COMPANY arising from such THIRD PARTY’S manufacture, use, import, offer for sale or sale of SELECTED PRODUCT, any damages or other monetary awards or payments in settlement recovered by COMPANY with respect to such infringement or misappropriation shall be applied first to defray the costs and expenses incurred by COMPANY in the action. Any remainder of the net amount recovered by COMPANY (after payment of amounts owed to others in respect of such recovery) shall be shared by the

-44-

PARTIES as follows: seventy-five percent (75%) of such remainder shall be retained by COMPANY and twenty-five percent (25%) of such remainder shall be retained by NEKTAR AL.

15.4 Termination by COMPANY. COMPANY shall have the right to terminate this AGREEMENT in its entirety at any time, without cause, upon sixty (60) days’ prior written notice to NEKTAR AL, in which case, (a) if COMPANY has not paid NEKTAR AL the first milestone payment in Schedule II, COMPANY will pay such amount to NEKTAR AL prior to the effective date of termination of this AGREEMENT, (b) prior to the effective date of such termination, COMPANY will pay NEKTAR AL the amount of two hundred fifty thousand dollars ($250,000) to reimburse NEKTAR AL for transactional and administrative costs incurred in connection with this AGREEMENT, and (c) in the case of non-binding forecasts for SELECTED REAGENT, within thirty (30) days of the effective date of such termination, COMPANY will purchase from NEKTAR AL the amount of SELECTED REAGENT in accordance with COMPANY’s most recent non-binding forecasts for supply of SELECTED REAGENT made under this AGREEMENT for the upcoming twelve (12) month period prior to COMPANY’s decision to terminate this AGREEMENT and (b) notwithstanding anything to the contrary herein, the provisions of Sections 2.1, 2.2, 2.4, 2.5, 4.4, 4.6, 5, 6, 7.2, 7.5 and 8 shall survive such termination until the last commercial sale of SELECTED PRODUCT made with SELECTED REAGENT purchased from NEKTAR AL (in the case of Section 7.2, solely with respect to NET SALES of SELECTED PRODUCT made with SELECTED REAGENT purchased from NEKTAR AL).

15.6.2 Notwithstanding anything in this AGREEMENT to the contrary, if this AGREEMENT is terminated for any reason whatsoever, other than due to COMPANY’S termination for NEKTAR AL’S failure to comply with the material terms of this AGREEMENT under Section 15.2 or a termination by COMPANY under Section 15.4 if the CROSS-LICENSE AGREEMENT terminates prior to the date of expiration of the last-to-expire VALID ENZON PATENT CLAIM:

Subject to the foregoing (and Section 2.4.1(b)), if this AGREEMENT is terminated for any reason whatsoever, all licenses and sublicenses granted under this AGREEMENT shall automatically terminate and all licensed rights shall revert in their entirety to the respective licensor.

15.6.3 Subject to the limitations of liability and exclusions of damages provided for in this AGREEMENT, termination of this AGREEMENT by a PARTY shall not be an exclusive remedy and all other remedies will be available to the terminating PARTY, in equity and at LAW.

19.1 Generally. Except as otherwise set forth in Sections 9.4 and 19.2, NEKTAR AL and COMPANY agree that any dispute or controversy as to the validity, enforcement, construction, performance or breach of this AGREEMENT shall be settled by binding arbitration under the then current Commercial Arbitration Rules of the American Arbitration Association. Unless otherwise agreed in writing by the PARTIES, the arbitration shall be conducted by one neutral independent arbitrator appointed in accordance with such rules and who shall be a former U.S. District Court judge. The arbitrator shall determine what discovery will be permitted, based on the principle of limiting the cost and time which the PARTIES must expend on discovery, provided, the arbitrator shall permit such discovery as he or she deems necessary to achieve an equitable resolution of the dispute. The decision and/or award rendered by the arbitrator shall be written, final and non-appealable and may be entered in any court of competent jurisdiction. The costs of any arbitration, including administrative fees and fees of the arbitrators, shall be shared equally by the PARTIES, unless otherwise specified by the arbitrator. Each PARTY shall bear the cost of its own attorneys’ and expert fees, provided that the arbitrator may in their discretion award to the prevailing PARTY the costs and expenses incurred by the prevailing PARTY in connection with the arbitration proceeding. Notwithstanding the provisions of Section 15.2, in the event a PARTY disputes in good faith an alleged failure to comply with the material terms of this AGREEMENT during the applicable cure period under Section 15.2, then such cure period shall be tolled pending final resolution of the dispute in accordance with this Section 19.1; provided, however, that if the disputed failure is a failure of COMPANY to comply with the terms of Section 11.4 and such dispute is resolved in NEKTAR AL’s favor, NEKTAR AL shall have the right to terminate this AGREEMENT upon written notice to COMPANY if COMPANY does not comply with such section within sixty (60) days from the date on which such dispute is resolved.

19.2 Any dispute or controversy relating to the inventorship and ownership of any invention or the scope, validity, enforceability or infringement of any intellectual property rights covering the composition of matter, method of making or method of using SELECTED REAGENT or SELECTED PRODUCT shall be submitted to a court of competent jurisdiction in the territory in which such intellectual property rights were granted or arose.

Neither PARTY shall be held liable or responsible to the other PARTY nor be deemed to have defaulted under or breached this AGREEMENT for failure or delay in fulfilling or performing any term of this AGREEMENT to the extent, and for so long as, such failure or delay is caused by or results from causes beyond the reasonable control of the affected PARTY; provided, however, that the foregoing shall not be applied to excuse or delay any payment obligation of COMPANY under this AGREEMENT.

20.2 Severability. All the terms and provisions of this AGREEMENT are distinct and severable, and if any term or provision is held unenforceable, illegal or void in whole or in part by any court, regulatory authority or other competent authority it shall to that extent be deemed not to form part of this AGREEMENT, and the enforceability, legality and validity of the remainder of this AGREEMENT shall not be affected thereby.

20.6 No Partnership. The relationship of the PARTIES is that of independent contractors and this AGREEMENT shall not operate so as to create a partnership or joint venture of any kind between the PARTIES.

20.7 Construction. The PARTIES have participated jointly in the negotiation and drafting of this AGREEMENT.

Except where the context otherwise requires, where used, the singular shall include the plural, the plural the singular, and the use of any gender shall be applicable to all genders. The captions of this AGREEMENT are for convenience of reference only and in no way define, describe, extend or limit the scope or intent of this AGREEMENT or the intent of any provision contained in this AGREEMENT.
