2. GRANT OF RIGHTS.

2.1 License Grants from CyDex to Company.

(a) Licensed Patents. Subject to the terms and conditions of this Agreement, including but not limited to payment of the amounts set forth in Section 4.1 below, CyDex hereby grants to Company an exclusive (even as against CyDex and its Affiliates), nontransferable (except with respect to the assignment provision in Section 14.15) limited license during the Term under the Licensed Patents, solely to make, have made (pursuant to Section 2.4), use, sell, offer for sale and import the Licensed Products in the Territory in and for the Field. (No license, exclusive or nonexclusive, is granted hereunder under the Licensed Patents, except to so make, have made, use, sell, offer for sale and import the Licensed Products in the Territory in and for the Field.) Notwithstanding the foregoing, to the extent that any Licensed Patents are licensed to CyDex or its Affiliates by a Third Party on a non-exclusive basis, the license granted to Company in the foregoing sentence shall be exclusive as to CyDex and its Affiliates and non-exclusive as to any Third Party. For clarity, as CyDex is unable to grant Company any rights that it does not have, in the event that CyDex obtains a non-exclusive license from a Third Party for intellectual property necessary for Company to perform its obligations hereunder, then CyDex shall pass on such rights to Company hereunder via a license that grants rights that are non-exclusive with respect to Third Parties but that is exclusive with respect to CyDex and its Affiliates. Company may not make, use, sell, offer for sale, or import the Licensed Products for any other purposes than those granted to it in this Agreement. Company may not sublicense the Licensed Patents, except as expressly set forth in Sections 2.3 and 2.4 below.

(b) Captisol Data Package. Subject to the terms and conditions of this Agreement, CyDex hereby grants to Company an exclusive (even as against CyDex and its Affiliates), nontransferable (except with respect to the assignment provision in Section 14.15) license during the Term under CyDex’s rights in and to the Captisol Data Package, solely to make, have made, use, sell, offer for sale and import the Licensed Products in the Territory in and for the Field. CyDex shall make its personnel reasonably available to Company and its Contract Manufacturers to respond to informational inquiries and provide technical assistance related to the Captisol Data Package. Company may sublicense its rights in and to the Captisol Data Package, as expressly set forth in Sections 2.3 and 2.4 below

(c) Scope of Licenses. CyDex grants no licenses or rights to use other than as expressly set forth herein. Without limiting the generality of the foregoing, CyDex grants no rights

6

to Company to manufacture, import, sell or offer for sale bulk Captisol; provided, however, that Company may provide Captisol to bona fide collaborators in order to help Company to make, have made (pursuant to Section 2.4), use, sell, offer for sale or import the Licensed Products in the Territory in the Field. Licensee acknowledges that not all rights of CyDex related to Captisol are included within the rights licensed hereunder, given that CyDex shall supply Company’s requirements of Captisol for the Licensed Products. Company shall not attempt to reverse engineer, deconstruct or in any way determine the structure or composition of Captisol except as and to the extent reasonably required to determine an optimal formulation of the Licensed Product, and such structure and composition of Captisol (as and if so determined) shall be considered Confidential Information of CyDex; [***] CyDex shall not be liable to Company for violation of Company’s exclusive rights hereunder by parties which are not Affiliates or licensees of CyDex except to the extent CyDex has contributed to such violation. Company acknowledges and agrees that except as is expressly set forth in this Agreement (i) CyDex shall not be required to obtain or maintain patent rights in the Territory for the Licensed Patents, (ii) CyDex shall not be restricted in making sales of Captisol or, except as provided herein for the Licensed Products and/or Competing Products, licensing rights to other parties, and (iii) CyDex does not warrant or indemnify Licensee or its Affiliates and Sublicensees against the Licensed Products infringing Third Party rights.

2.2 Grant of License from Company to CyDex. Company hereby grants to CyDex a nonexclusive, transferable, perpetual, worldwide and royalty-free license, with the right to grant sublicenses (through multiple tiers of sublicensees), under Company’s and its Affiliates’ and Sublicensees’ rights in and to Captisol Improvements to develop, make, have made, use, market, distribute, import, sell and offer for sale Captisol, any Captisol Improvement and products formulated with Captisol or any Captisol Improvement (other than the Licensed Products in the Field). If during the Term any of (a) Company, (b) Affiliates to whom Company has provided rights under the licenses granted to Company by CyDex pursuant to Section 2.1, or (c) Sublicensees pursuant to the practice of their respective sublicenses from Company under Section 2.3, file any patent application claiming any Captisol Improvement anywhere in the world, CyDex shall be deemed automatically to have a nonexclusive, transferable, perpetual, worldwide and royalty-free license, with the right to grant sublicenses (through multiple tiers of sublicensees), under the claims relating specifically to any Captisol Improvement to make, have made, use, market, distribute, import, sell, and offer for sale Captisol. Company shall provide prompt notice of any Captisol Improvement.

2.3 Sublicensing. Company shall have the right to grant sublicenses (through one or more tiers of sublicenses) to its Affiliates and licensees of the Licensed Products (collectively “Sublicensees”) under the licenses granted to Company pursuant to Section 2.1; provided, however, Company warrants and shall procure, as a condition precedent thereto, that each such Sublicensee shall first be advised of the restrictions set forth in this Agreement with respect to the transfer of the rights sublicensed to such Sublicensee and such Sublicensee shall enter into an agreement with Company (with CyDex named as an intended third-party beneficiary) pursuant to which such Sublicensee shall acknowledge and agree to observe and be bound by the applicable restrictions set forth in this Agreement. Other than as specifically provided in this Section 2.3 and Section 2.4, Company shall not have the right to grant sublicenses to any Third Party under the licenses granted pursuant to Section 2.1.

terms and conditions of this Agreement and Company shall be and remain fully responsible for the compliance by such Sublicensees with the terms and conditions of this Agreement as if such Sublicensees were Company hereunder.

2.4 Contracting. Company may manufacture the Licensed Products (but not the bulk Captisol) or contract the manufacture of the Licensed Products (but not the manufacture of bulk Captisol) with Third Party manufacturers (collectively “Contract Manufacturers”). To the extent necessary to engage a Contract Manufacturer for a Licensed Product, Company shall be permitted under this Agreement to grant any such Contract Manufacturer a sublicense under the licenses granted to Company pursuant to Section 2.1 solely for such purposes; provided, however, Company warrants and shall procure, as a condition precedent thereto, that (a) any such Contract Manufacturer shall first be advised of the restrictions set forth in this Agreement with respect to the transfer of the rights licensed to Company and its Sublicensees hereunder and (b) any such Contract Manufacturer shall enter into an agreement with Company pursuant to which such Contract Manufacturer shall acknowledge and agree to observe and be bound by the applicable restrictions set forth in this Agreement. Company shall ensure that all of its Contract Manufacturers shall comply with the terms and conditions of this Agreement and shall remain fully responsible for the compliance by such Contract Manufacturers with the terms and conditions of this Agreement as if such Contract Manufacturers were Company hereunder.

2.5 Bankruptcy Code. All rights and licenses granted under or pursuant to this Agreement by CyDex to Company are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The parties agree that Company, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code.

In addition, CyDex represents and warrants that it is not in breach of any of its obligations to such Upstream Licensors and covenants that it shall maintain its rights under and shall comply with the terms of its agreements with such Upstream Licensors throughout the Term. Furthermore, CyDex represents and warrants that it shall not amend, modify or supplement the terms of, or waive any rights under any such agreements if the same would have the effect of limiting or further restricting Company’s rights or expanding Company’s obligations hereunder.

2.7 Negative Covenants by CyDex.

(a) During the Term (on a country-by-country basis), neither CyDex nor any of its Affiliates shall directly themselves, nor provide any Third Party any assistance whatsoever, nor grant any Third Party any right or license under any of the Licensed Patents to, research, develop,

(b) During the Term (on a country-by-country basis), neither CyDex nor any of its Affiliates shall supply Captisol or a Captisol Related Compound to any Third Party (other than a Company designee) which it knows or should know will use it for a Licensed Product or a Competing Product. If during the Term (on a country-by-country basis), any such Third Party, or any other Third Party that acquires any Captisol Related Compound, utilizes such Captisol Related Compound in a Licensed Product or Competing Product, CyDex shall immediately cease and cause its Affiliates and any other Third Party to immediately cease supplying any Captisol Related Products to the offending Third Party for the duration of the Term or until (if sooner) assurances reasonably satisfactory to Company that the infringing use has ended and will not resume have been obtained.

(ii) The royalty shall be reduced with respect to Net Sales in a particular country by deducting (a) 50% of any and all royalties paid by Company, its Affiliates and/or Sublicensees to any Third Party for any additional solubility technology that is incorporated in a Licensed Product in such country, up to a maximum reduction of 50% in the aggregate of the royalty owing for Net Sales in such country; (b) 100% of any and all royalties paid for any license that the parties mutually determine in good faith would be prudent to obtain given the potential to resolve or avoid any claims that Captisol, or specifically the Captisol element of a Licensed Product infringes or misappropriates the intellectual property rights of any Third Party in such country; and (c) any final, unappealed judgment awarded against Company, its Affiliates or Sublicensees for damages for infringement of Third Party intellectual property rights with respect to making, having made, using, selling, offering for sale or importing Captisol, or specifically the Captisol element of a Licensed Product in such country. Company shall use commercially reasonable efforts to minimize any such royalties or other payments to Third Parties on account of sales of Licensed Products hereunder.

(iii) In the event that a Licensed Product is commercialized in combination with one or more products which are themselves not Licensed Products under this Agreement for a single price, the Net Sales for such Licensed Product shall be calculated by multiplying the sales price of such combination sale by the fraction A/(A+B) where A is the fair market value of the Product and B is the fair market value of the other product(s) in the combination sale. If the fair market value for any product sold in combination with a Licensed Product cannot be reasonably determined, the price attributed to such product shall be based on the relative cost of goods for such product, as determined in accordance with U.S. GAAP.

(iv) All royalties payable to CyDex pursuant to Section 4.1(c) shall be due and payable within [***] after the conclusion of each calendar quarter, provided that within [***] after the conclusion of each Company fiscal year Company may provide notice to CyDex of any adjustments necessary to account for any royalties which were overpaid or underpaid for such prior fiscal year’s calendar quarters (as determined from Company’s end of fiscal year external audit), and the parties shall promptly true-up for any such adjustments which are mutually determined to be correct.

In establishing the royalty structure hereunder, the parties recognize, and Company acknowledges, the substantial value of the various obligations being undertaken by CyDex under this Agreement, in addition to the grant of the licenses under the Captisol Data Package as well as under the Licensed Patents, to enable the rapid and effective market introduction of the Licensed Products. The parties have agreed to the payment structure set forth herein as a convenient and fair mechanism to compensate CyDex for these obligations.

4.2 Taxes. All amounts due hereunder exclude all applicable withholding, sales, use, and other taxes and duties, and Company shall be responsible for payment of all such taxes (other than taxes based on CyDex’s income) and duties and any related penalties and interest, arising from the payment of amounts due under this Agreement. The parties agree to cooperate with one another and use commercially reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Company to CyDex under this Agreement. To the extent Company is required to withhold taxes on any payment to CyDex,

*** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

11

Company shall pay the amounts of such taxes to the proper governmental authority in a timely manner and promptly transmit to CyDex official receipts issued by the appropriate taxing authority and/or an official tax certificate, or such other evidence as CyDex may reasonably request, to establish that such taxes have been paid. CyDex shall provide Company any tax forms that may be reasonably necessary in order for Company to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. CyDex shall use commercially reasonable efforts to provide any such tax forms to Company at least 45 days before the due date for any payment for which CyDex desires that Company apply a reduced withholding rate. Each party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the party bearing such withholding tax or value added tax.

6. DEVELOPMENT AND COMMERCIALIZATION BY COMPANY.

6.1 Costs and Expenses. Company shall be solely responsible for all costs and expenses related to its development and commercialization of the Licensed Products, including without limitation costs and expenses associated with all preclinical activities and clinical trials, and all regulatory filings and proceedings relating to the Licensed Products.

6.2 In Vivo Studies. If Company wishes to conduct any in vivo study (preclinical or clinical, in animals or in humans, each a “Study”) of a Licensed Product utilizing Captisol, the following provisions shall apply:

(a) Dosing. Company shall not exceed the maximum allowable dosing levels of Captisol specified in CyDex’s then-current clinical dosing matrix (which shall be provided by CyDex to Company from time to time) without the written consent of CyDex.

13

the scope of this Agreement, and, subject to Company’s additional rights under the Supply Agreement, shall not use any other cyclodextrin product supplied by a Third Party.

(d) Reporting and Study Data. Within three months after receipt of the final Study report for a Study, Company shall provide to CyDex a summary of the data and results of each Study that pertain solely to Captisol, and subject to Section 8, Company hereby grants to CyDex a non-exclusive, royalty-free license (with the right to sublicense) to use and disclose such data solely as necessary for regulatory purposes, including without limitation to update the DMF for Captisol.

(e) Responsibility. Company has the freedom to formulate and design each Study, and (as between Company and CyDex) Company is solely responsible for executing each Study; and so it is reasonable that, and the parties agree that, Company shall be solely responsible therefor and for any effects or consequences of the formulation, design and execution of each Study.

6.3 Right of Reference. Company shall have the right to reference the DMF solely in connection with Company’s regulatory filings (including INDs, NDAs, etc.) submitted in connection with obtaining Marketing Approval for a Licensed Product. CyDex shall use commercially reasonable efforts to keep its DMF in good standing throughout the Term.

6.4 Access to Company’s Data. CyDex shall have the right to reference and utilize all toxicology/safety and other relevant scientific data developed on Captisol alone (and not in conjunction with a Licensed Product) by Company, its Sublicensees or Affiliates, at no cost to CyDex. Upon request by CyDex, Company shall either provide CyDex, at CyDex’s sole expense, with a copy of all such data or shall make such data accessible to CyDex at times and locations reasonably agreeable to CyDex and Company subject to the provisions of Section 8.

7. REGULATORY MATTERS.

7.1 Captisol Information Submitted for Regulatory Review. Except as otherwise set forth herein, Company shall be solely responsible for all communications with regulatory agencies in connection with the Licensed Products, provided CyDex shall reasonably cooperate with Company with respect to any interactions with regulatory authorities concerning Captisol. Company shall provide CyDex with copies of the portions of all regulatory submissions containing Captisol data alone (and not in conjunction with any Licensed Product) 14 days before submission and shall allow CyDex to review and comment upon said submissions. The contents of each such submission shall be deemed to be Confidential Information of Company, subject to the terms and provisions of Section 8 below. Company shall promptly inform CyDex of meetings with the FDA (or other regulatory agencies in the Territory) regarding Captisol. If Company submits written responses to the FDA that include data on Captisol alone, CyDex shall be permitted to review such written materials 14 days before submission. If CyDex reasonably objects to the contents of such written responses relating to Captisol, the parties agree to cooperate in working toward a reasonable and mutually agreeable response; provided, however, that Company shall be entitled to in good faith make the final determination as to the contents of any such materials.

7.2 Material Safety. CyDex shall provide Company, in writing, from time to time, with (a) relevant material information currently known to it regarding handling precautions, toxicity and hazards with respect to Captisol, and (b) the then-current material safety data sheet for Captisol. Notwithstanding the foregoing or anything in this Agreement to the contrary, Company is solely

14

responsible for (i) use of all documentation provided by CyDex, including without limitation, use in any regulatory submission to the FDA or any other regulatory agency in the Territory, (ii) document control and retention, and (iii) determining the suitability of any documentation provided by CyDex hereunder for use in any regulatory submission.

7.3 Adverse Event Reporting. Company shall adhere, and shall require that its Affiliates, Sublicensees, co-marketers and distributors adhere, to all requirements of applicable law and regulations that relate to the reporting and investigation of any adverse event, including without limitation an unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease, whether or not considered Captisol or Licensed Product-related, which occurs or worsens following administration of Captisol or Licensed Product. Each party shall provide the other with copies of all reports it obtains (either directly or through any Sublicensee or licensee) of any adverse event which is serious (e.g., any such adverse event involving Captisol or the Licensed Product that results in death, is life-threatening, requires or prolongs inpatient hospitalization, results in disability, congenital anomaly or is medically important (i.e., may require other medical or surgical intervention to prevent other serious criteria from occurring)) which such party has reason to believe are associated with Captisol within 14 days following (i) submission of any such report to any regulatory agency, or (ii) receipt from such party’s Sublicensee, licensee, co-marketer or distributor of any such report to any regulatory agency. Company shall also advise CyDex regarding any proposed labeling or registration dossier changes affecting Captisol. Reports from Company shall be delivered to the attention of Chief Scientific Officer, CyDex, with a copy to Chief Executive Officer, CyDex, at the address set forth in Section 14.7. The parties shall mutually cooperate with regard to investigation of any such serious adverse event, whether experienced by Company, CyDex or any other Affiliate, Sublicensee, sublicensee, co-marketer or distributor of CyDex or Company.

7.4 Safety Agreement. Upon request by Company, CyDex shall negotiate in good faith a separate safety agreement (the “Safety Agreement”), for each proposed Licensed Product, at least 120 days before submission of an IND related to such proposed Licensed Product (or, for any proposed Licensed Products for which the IND was submitted before the Effective Date, then as soon as practicable after the Effective Date). The Safety Agreement would be anticipated to provide details related to the management of serious Adverse Events that occur during clinical trials, including safety issues rising from pre-clinical research and other safety and reporting practices and procedures, detailing obligations related to the development and commercialization of the Licensed Product in compliance with all applicable laws, rules, and regulations.

8. CONFIDENTIALITY.

8.1 Definition. Company and CyDex each recognizes that during the Term, it may be necessary for a party (the “Disclosing Party”) to provide Confidential Information (as defined herein) to the other party (the “Receiving Party”) that is highly valuable, the disclosure of which would be highly prejudicial to such party. The disclosure and use of Confidential Information shall be governed by the provisions of this Section 8. Neither Company nor CyDex nor their Affiliates shall use the other’s Confidential Information except as expressly permitted in this Agreement. For purposes of this Agreement, “Confidential Information” means all information disclosed by the Disclosing Party to the Receiving Party and which reasonably ought to have been understood to be confidential and/or non-public information at the time disclosed to the Receiving Party, or which is designated in writing by the Disclosing Party as “Confidential” (or equivalent), or which when

15

disclosed orally to the Receiving Party is declared to be confidential by the Disclosing Party and is so confirmed in a writing delivered to the Receiving Party within 30 days of such oral disclosure, including but not limited to product specifications, data, know-how, formulations, product concepts, sample materials, business and technical information, financial data, batch records, trade secrets, processes, techniques, algorithms, programs, designs, drawings, and any other information related to a party’s present or future products, sales, suppliers, customers, employees, investors or business. Without limiting the generality of the foregoing, CyDex’s Confidential Information includes all materials provided as part of the Captisol Data Package.

8.2 Obligation. CyDex and Company agree that they will disclose the other party’s Confidential Information to its own (or its 100% stockholder’s, or with respect to Company, its Sublicensees’) officers, employees, consultants and agents only if and to the extent necessary to carry out their respective responsibilities under this Agreement or in accordance with the exercise of their rights under this Agreement, and such disclosure shall be limited to the maximum extent possible consistent with such responsibilities and rights. Except as set forth in the foregoing sentence, neither party shall disclose Confidential Information of the other to any Third Party without the other’s prior written consent; provided, however, consent shall not be required to the extent such Confidential Information is disclosed for diligence purposes to Company’s potential Sublicensees, sources of funding or acquirers of any or all of the Company’s assets to which this Agreement relates. In all events, however, any and all disclosure to a Third Party shall be pursuant to the terms of a non-disclosure/nonuse agreement no less restrictive than this Section 8. The party which disclosed Confidential Information of the other to any Third Party or Affiliate shall be responsible and liable for any disclosure or use by such Third Party or Affiliate (or its disclosees) which would have violated this Agreement if committed by the party itself. Neither party shall use Confidential Information of the other except as expressly allowed by and for the purposes of this Agreement. Each party shall take such action to preserve the confidentiality of each other’s Confidential Information as it would customarily take to preserve the confidentiality of its own Confidential Information (but in no event less than a reasonable standard of care). Upon expiration or termination of this Agreement, each party, upon the other’s request, shall return or destroy (at disclosing party’s discretion) all the Confidential Information disclosed to the other party pursuant to this Agreement, including all copies and extracts of documents, within 60 days of the request, except for one copy which may be retained in its confidential files for archive purposes.

8.3 Exceptions. The use and non-disclosure obligations set forth in this Section 8 shall not apply to any Confidential Information, or portion thereof, that the Receiving Party can demonstrate by competent evidence:

(a) at the time of disclosure is in the public domain;

(b) after disclosure, becomes part of the public domain, by publication or otherwise, through no fault of the Receiving Party or its disclosees;

(c) at the time of disclosure is already in the Receiving Party’s possession, and such prior possession can be properly demonstrated by the Receiving Party, with the exception of Confidential Information exchanged between parties before the execution of this Agreement;

(d) is made available to the Receiving Party by an independent Third Party without obligation of confidentiality; provided, however, that to the Receiving Party’s knowledge,

16

such information was not obtained by said Third Party, directly or indirectly, from the Disclosing Party hereunder; or

(e) is independently developed by an employee of the Receiving Party not accessing or utilizing the Disclosing Party’s information.

In addition, the Receiving Party may disclose information that is required to be disclosed by law, by a valid order of a court or by order or regulation of a governmental agency including but not limited to, regulations of the SEC or in the course of arbitration or litigation; provided, however, that in all cases the Receiving Party shall give the other party prompt notice of the pending disclosure and use commercially reasonable efforts to obtain, or to assist the Disclosing Party in obtaining, a protective order or confidential-treatment order preventing or limiting (to the greatest possible extent and for the longest possible period) the disclosure and/or requiring that the Confidential Information so disclosed be used only for the purposes for which the law or regulation required, or for which the order was issued.

8.4 Injunction. Each party agrees that should it breach or threaten to breach any provisions of this Section 8, the Disclosing Party will suffer irreparable damages and its remedy at law will be inadequate. Upon any breach or threatened breach by the Receiving Party of this Section 8, the Disclosing Party shall be entitled to seek temporary, preliminary and/or permanent injunctive relief in addition to any other remedy which it may have, without need to post any bond or security, in addition to any and all other legal and equitable rights and remedies available to the Disclosing Party.

8.5 Third Party Information.

(a) Company acknowledges that CyDex’s Confidential Information and DMF include information developed by Pfizer, Inc. (“Pfizer”) that is confidential to both CyDex and Pfizer. Only to the extent that confidential information of Pfizer is disclosed to Company hereunder, and only as required by CyDex’s pre-existing contractual obligations to Pfizer, then Pfizer is a limited third party beneficiary of only this Section 8 of this Agreement and may seek remedies pursuant to it, but only in accordance with its terms.

(b) Both parties agree not to disclose to the other party any Confidential Information of a Third Party which is in the possession of such party, unless the other party has given an express prior written consent (which specifies the owner of such Confidential Information) to receive such particular Confidential Information.

8.6 Public Announcements. The parties shall mutually agree on any press release to be issued upon execution of this Agreement. Neither party shall make any subsequent public announcement concerning this Agreement or the terms hereof not previously made public without the prior written approval of the other party with regard to the form, content, and precise timing of such announcement, except as may be required to be made by either party in order to comply with applicable law, regulations, court orders, or tax, securities filings, financing arrangements, acquisitions, or sublicenses. Such consent shall not be unreasonably withheld or delayed by such other party. Before any such public announcement, the party wishing to make the announcement shall submit a draft of the proposed announcement to the other party in sufficient time to enable such other party to consider and comment thereon. In addition, Company shall not, without at least 14

17

days’ prior written notice to CyDex (except to the extent such a notice period would not be allowed due to an affirmative requirement of applicable law for immediate disclosure to governmental authorities), state or suggest orally or in writing to any governmental authorities, physicians or other Third Parties that Captisol (sulfobutylether ß cyclodextrin) has any safety or efficacy issues or that any Adverse Event was due to Captisol. Upon providing such notice, Company shall not be required to provide any additional notices to CyDex for any subsequent statements (oral or written) concerning the same issue. Similarly, CyDex shall not, without at least 14 days’ prior written notice to Company (except to the extent such a notice period would not be allowed due to an affirmative requirement of applicable law for immediate disclosure to governmental authorities), state or suggest orally or in writing to any governmental authorities, physicians or other Third Parties that a Compound or Licensed Product has any safety or efficacy issues or that any Adverse Event was due to a Compound or a Licensed Product. Upon providing such notice, CyDex shall not be required to provide any additional notices to Company for any subsequent statements (oral or written) concerning the same issue.

(c) For the avoidance of doubt, subject to Sections 12.2(a) and (b) each party shall be solely responsible for all decisions and actions pertaining to the prosecution and maintenance of patents owned solely by such party.

12.3 Infringement by Third Parties.

(a) Each party shall promptly notify the other party in writing of any actual or threatened infringement, misappropriation or other violation by a Third Party of any Licensed Patents in the Field and in the Territory (“Third Party Infringement”) of which it becomes aware.

(b) Existing Rights. CyDex shall have the initial right (but not the obligation), at its own expense, to initiate and control any action to enforce the Licensed Patents against any Third Party Infringement and may name Company as a party plaintiff solely to the extent required to maintain standing, providing CyDex shall reimburse Company for any such costs incurred by Company therefor. If CyDex does not obtain agreement from the alleged infringer to desist or fails to initiate an infringement action within: (i) 60 days following receipt of notice of the alleged infringement (120 days if CyDex is in active negotiations with such infringer), or (ii) 30 days before the expiration date for filing such actions, whichever comes first, Company shall have the right, at its sole discretion, to initiate and control an action to enforce the Licensed Patents against such Third Party Infringement at its sole expense and may name CyDex as a party plaintiff solely to the extent required to maintain standing; provided, however, Company shall reimburse CyDex for any costs incurred by CyDex therefor, provided, further, Company shall not enforce any Licensed Patents to the extent such Third Party Infringement is unrelated to the development, filing for regulatory approval for, manufacture, offer for sale, sale, import or use of a Competing Product. Before commencing an action, the party bringing such action (the “Enforcing Party”) shall consult with the other party and give consideration to the other party’s recommendations regarding the proposed action. The Enforcing Party shall give the other party timely notice of any proposed settlement of any such action instituted by the Enforcing Party and shall not, without the prior written consent of the other party, enter into any settlement. Notwithstanding the foregoing, if CyDex is the Enforcing Party and such Third Party Infringement is unrelated to a Competing Product or Company is the Enforcing Party (and thus by default such Third Party Infringement is related to a Competing Product), then in either such case the Enforcing Party shall not be required to obtain the other party’s prior written consent to settle an action so long as such settlement does not: (i) adversely affect the validity, enforceability or scope of any of the Licensed Patents, (ii) give rise to liability of the other party or its Affiliates, (iii) admit non-infringement of any Licensed Patents, or (iv) otherwise impair the other party’s rights in any Licensed Patents or under this Agreement. Any recoveries resulting from an action relating to a claim of Third Party Infringement of the Licensed Patents (including any recoveries resulting from settlement) shall first be applied against payment of each party’s costs and expenses incurred in connection therewith. If CyDex was the Enforcing Party, then any remaining recoveries shall be retained by CyDex, provided that if such Third Party Infringement is related to the development, filing for regulatory approval for, manufacture, offer for sale, sale, import or use of a Competing Product, then any remaining recoveries shall be split such that CyDex retains [***] and Company retains [***] of such remainder. If Company was the Enforcing Party, then any remaining recoveries shall be retained solely by Company but shall be treated as Net Sales for purposes of determining royalties under Section 4.1(c).

(c) New Rights. The parties shall cooperate to take whatever, if any, action they mutually agree upon in writing and in their respective discretion against the alleged infringer of New

*** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

23

Rights which are jointly owned in accordance with Section 12.1(b). Such agreement shall include actions to be taken by each party and the allocation of expenses and recoveries related to such action. Neither party shall take any such action against the alleged infringer without the written consent of the other party.

(d) For the avoidance of doubt, subject to Sections 12.3(a), (b) and (c), each party shall be solely responsible for all decisions and actions pertaining to the enforcement of patents owned solely by such party.

13. TERM AND TERMINATION.

13.1 Term. The term of this Agreement (the “Term”) shall commence on the Effective Date and shall continue in effect thereafter on a country-by-country basis until the later of (i) the fifth anniversary of the First Commercial Sale of a Licensed Product in the Territory (and irrespective of whether such First Commercial Sale occurred in the applicable country or another country in the Territory) or (ii) the date that there no longer exists any Valid Claim in the applicable country.

13.2 Termination by Company for Convenience.

(a) Company may terminate this Agreement, in its entirety, for convenience at its election, upon 90 days’ prior express written notice to CyDex. If the Agreement is terminated by Company pursuant to this Section 13.2(a), within 30 days after such termination, Company shall pay to CyDex all payments owing at the date of termination.

(b) Company may terminate this Agreement, solely with respect to any country(ies) in the Territory in which Generic Captisol is being manufactured or sold on a commercial basis, at its election, upon [***] prior express written notice to CyDex. If the Agreement is terminated by Company with respect to any such country(ies) pursuant to this Section 13.2(b), within 30 days after such termination, Company shall pay to CyDex all royalty payments owing at the date of termination with respect to prior Net Sales in such country.

13.3 Termination for Breach. If either party should violate or fail to perform any material term or covenant of this Agreement, then the other party may give written notice of such default to such party. If such party should fail to cure such default within 60 days (or 10 days with respect to any payment obligation) after such notice, the other party shall have the right to terminate this Agreement by a second written notice (a “Notice of Termination”) to such party. If Notice of Termination is sent to such party, this Agreement shall automatically terminate on the effective date of such notice. In the event of a material breach by CyDex, if CyDex fails to cure such default within the applicable cure period under this Section 13.3 Company may elect to either (i) terminate this Agreement in accordance with the provisions set forth in this Section 13.3 or (ii) without limiting any other legal or equitable remedies that Company may have, continue this Agreement in full force and effect, but with the milestones and royalties otherwise due hereunder to be reduced by an amount to be mutually agreed upon by the parties.

13.4 Termination for Bankruptcy. Either party may terminate this Agreement immediately upon written notice to the other party in the event that the other party has a petition in bankruptcy filed against it that is not dismissed within 60 days of such filing, files a petition in bankruptcy, or makes an assignment for the benefit of creditors.

24

13.5 Termination of the Supply Agreement. If the Supply Agreement is terminated by CyDex pursuant to Section 13.2 thereof for Company’s material breach of the Supply Agreement, then CyDex shall have the right to terminate this Agreement upon written notice to Company. If the Supply Agreement is terminated in accordance with its terms (except for by CyDex for Company’s material breach), Company shall have the right to terminate this Agreement upon written notice to CyDex.

13.6 Effect of Termination.

(a) Following the termination by Company under Section 13.2 or by CyDex for Company’s breach under Section 13.3, all rights granted to Company herein shall immediately terminate and each party shall promptly return all relevant records and materials in its possession or control containing the other party’s Confidential Information with respect to which the former party does not retain rights hereunder; provided, however, that each party may retain one archival copy of such records and materials solely to be able to monitor its obligations that survive under this Agreement.

(b) Upon the natural expiration of the Term as to a country, the licenses granted in Section 2.1 shall become perpetual, fully paid-up and royalty-free as to such country.

(c) Upon any early termination of this Agreement and until the first anniversary of such early termination, Company shall have the right to sell its remaining inventory of Licensed Products so long as Company has fully paid, and continues to fully pay when due, any and all payments owed to CyDex, and provides royalty reports as called for hereunder, and Company otherwise is not in continuing material breach of this Agreement.

13.7 Survival. Notwithstanding any other provisions of this Agreement, any liability or obligation of either party to the other for acts or omissions before the termination or expiration of this Agreement shall survive the termination or expiration of this Agreement. Such termination or expiration shall not relieve either party from obligations that are expressly indicated or obviously intended to survive termination or expiration of this Agreement, nor shall any termination or expiration of this Agreement relieve Company of its obligation to pay CyDex, subject to the terms herein, (i) royalties for all Licensed Products sold by Company, its Affiliates or Sublicensees before the effective date of such expiration or termination (or pursuant to Section 13.6(c)), or (ii) sums due in respect of Captisol shipped before termination or expiration of this Agreement. Sections 2.2 (Grant of License from Company to CyDex), 4.2 (Taxes), 4.3 (Late Payments), 5 (Records; Reports; Audit), 6.2(d) (Reporting and Study Data), 6.4 (Access to Company’s Data), 7.3 (Adverse Event Reporting), 8 (Confidentiality), 9.3 (Disclaimer), 10 (Indemnification), 11 (Limitation of Liability), 12 (Management of Intellectual Property), 13 (Term and Termination), and 14 (General Provisions) shall survive termination or expiration of this Agreement.

14. GENERAL PROVISIONS.

During the Term of this Agreement and for a period of one year thereafter, Company shall

25

not solicit, induce, encourage or attempt to induce or encourage any employee of CyDex to terminate his or her employment with CyDex or to breach any other obligation to CyDex; provided, that this sentence is not meant to encompass general solicitations such as may be found in newspaper advertisements and the like.

14.3 Arbitration.

(a) Procedure. Any and all disputes or controversies arising out of or relating to this Agreement shall be exclusively and finally resolved by binding arbitration in accordance with the commercial arbitration rules of the American Arbitration Association then in effect, in San Diego, California. The arbitration shall be conducted by an arbitrator reasonably knowledgeable about the pharmaceutical industry and acceptable to CyDex and Company. If CyDex and Company cannot agree on a single arbitrator within 30 days after a demand for arbitration has been made, CyDex shall appoint an arbitrator, Company shall appoint an arbitrator, the two (2) arbitrators shall appoint a third arbitrator, and the three arbitrators shall hear and decide the issue in controversy. If either party fails to appoint an arbitrator within 45 days after service of the demand for arbitration, then the arbitrator appointed by the other party shall arbitrate any controversy in accordance with this Section 14.3(a). Except as to the selection of arbitrators, the arbitration proceedings shall be conducted promptly and in accordance with the rules of the American Arbitration Association then in effect. The expenses of any arbitration, including the reasonable attorney fees of the prevailing party, shall be borne by the party deemed to be at fault or on a pro-rata basis should the arbitration conclude in a finding of mutual fault.

(b) Confidentiality of Proceedings. All arbitration proceedings hereunder shall be confidential and the arbitrator(s) shall issue appropriate protective orders to safeguard each party’s Confidential Information. Except as required by law, no party shall make (or instruct the arbitrator(s) to make) any public announcement with respect to the proceedings or decision of the arbitrator(s) without prior written consent of the other party.

(c) Interim Equitable Relief. Each party shall, in addition to all other remedies accorded by law (or in equity) and permitted by this Agreement, be entitled to equitable relief (including but not limited to interim injunctive relief) in any court having jurisdiction to protect its interests. Neither party shall commence any court proceeding or action against the other to resolve any dispute, except (i) to enforce an arbitral award rendered pursuant to this Section 14.3, or (ii) for such interim injunctive relief.

(d) Binding Effect. The provisions of this Section 14.3 shall survive any expiration or termination of this Agreement, and shall be severable and binding on the parties hereto,

26

notwithstanding that any other provision of this Agreement may be held or declared to be invalid, illegal or unenforceable.

14.4 Costs and Expenses. Except as otherwise expressly provided in this Agreement, each party shall bear all costs and expenses associated with the performance of such party’s obligations under this Agreement.

14.5 Further Assurances. The parties hereby covenant and agree without the necessity of any further consideration, to execute, acknowledge and deliver any and all such other documents and take any such other action as may be reasonably necessary or appropriate to carry out the intent and purposes of this Agreement.

14.6 Force Majeure. Neither party shall be liable for failure to perform, or delay in the performance of, its obligations under this Agreement (other than payment obligations) when such failure or delay is caused by an event of force majeure. For purposes of this Agreement, an event of force majeure means any event or circumstance beyond the reasonable control of the affected party and not reasonably preventable using industry standard practices, including but not limited to, war, insurrection, riot, fire, flood or other unusual weather condition, explosion, act of God, peril of the sea, sabotage, accident, embargo, act of governmental authority, compliance with governmental order on national defense requirements, or inability due to general industry wide shortages to obtain fuel, power, raw materials, labor or transportation facilities. If, due to any event of force majeure, either party shall be unable to fulfill its obligations under this Agreement (other than payment obligations), the affected party shall immediately notify the other party of such inability and of the period during which such inability is expected to continue, shall use commercially reasonable efforts to cure and remedy such non-performance and the time for performance shall be extended for a number of days equal to the duration of the force majeure, and the parties shall meet promptly to determine an equitable solution to the effects of such event. If any event of force majeure continues in effect for a period of 90 days or more, the party who is not claiming excuse from performance under such force majeure may terminate this Agreement by giving not less than 30 days’ notice to the other party on a country-by-country basis.

14.9 Public Announcements. No party shall use the name, trademark, trade name or logo of the other party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or public disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other party, such permission not to be unreasonably withheld, except as may be required by law or required by the rules of an applicable US national securities exchange or as permitted by Section 14.8. The parties agree that a party may disclose this Agreement and its terms, and material developments or material information generated under this Agreement, in (i) securities filings with the SEC (or equivalent foreign agency), or taxing authorities, to the extent required by law after complying with the procedure set forth in this Section 14.9, or (ii) under conditions of confidentiality/nonuse in connection with investment and similar corporate transactions.

14.10 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California (without giving effect to any conflicts of law principles that require the application of the law of a different state).

14.11 Entire Agreement; Amendment. This Agreement and the Supply Agreement and all Exhibits attached hereto or thereto contain the entire agreement of the parties relating to the subject matter hereof and thereof and supersede any and all prior or contemporaneous agreements, written or oral, between CyDex and Company relating to the subject matter hereof and thereof, including without limitation the Limited Clinical Use Agreement between the parties dated November 11, 2010, as amended October 4, 2011. Without limiting the foregoing, CyDex hereby acknowledges and agrees that Company owes no further payments under such prior agreements and to the extent there are any invoices that have yet to be paid or issued under such prior agreements, CyDex hereby releases Company and waives its rights to any such payments or amounts owed. Subject to the foregoing, neither party shall be relieved from any liability for any past breach of any such prior written agreements, for any strict liability claims or tort claims or from any indemnification obligation thereunder. In addition, any confidential information which was disclosed under such prior agreements shall remain confidential and shall be subject to the nondisclosure and nonuse provisions set forth in Section 8 of this Agreement. This Agreement may not be amended unless agreed to in writing by both parties.

28

14.12 Binding Effect. This Agreement shall be binding upon, and the rights and obligations hereof shall apply to CyDex and Company and any successor(s) and permitted assigns. The name of a party appearing herein shall be deemed to include the names of such party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement.

14.13 Waiver. The rights of either party under this Agreement may be exercised from time to time, singularly or in combination, and the exercise of one or more such rights shall not be deemed to be a waiver of any one or more of the others. No waiver of any breach of a term, provision or condition of this Agreement shall be deemed to have been made by either party unless such waiver is addressed in writing and signed by an authorized representative of that party. The failure of either party to insist upon the strict performance of any of the terms, provisions or conditions of this Agreement, or to exercise any option contained in this Agreement, shall not be construed as a waiver or relinquishment for the future of any such term, provision, condition or option or the waiver or relinquishment of any other term, provision, condition or option.

14.14 Severability. If any provision of this Agreement is determined by a final and binding court or arbitration judgment to be invalid, illegal or unenforceable to any extent, such provision shall not be not affected or impaired up to the limits of such invalidity, illegality or unenforceability; the validity, legality and enforceability of the remaining provisions of this Agreement shall not be affected or impaired in any way; and the parties agree to negotiate in good faith to replace such invalid, illegal and unenforceable provision (or portion of provision) with a valid, legal and enforceable provision that achieves, to the greatest lawful extent under this Agreement, the economic, business and other purposes of such invalid, illegal or unenforceable provision (or portion of provision). Subject to Section 13.1, this Agreement shall not be terminated or invalidated by any future determination that any or all of the Licensed Patents have expired or been invalidated.

14.15 Assignment. Neither party may assign its rights or delegate its obligations under this Agreement, in whole or in part, by operation of law or otherwise, to any Third Party without the prior written consent of the other party, which consent shall not be unreasonably withheld. Notwithstanding the foregoing, either party may assign in whole or in part its rights and/or delegate in whole or in part its obligations under this Agreement to an Affiliate or to any Third Party successors (including with respect to Company, Third Party successors to one or more Licensed Products), whether by way of merger, sale of assets to which this Agreement relates, sale of stock or otherwise, without prior written consent. As a condition to any permitted assignment hereunder, the assignee must expressly assume (for the express benefit of the party hereto which is not the assignor) the performance of the terms and obligations of this Agreement by such assignee. Furthermore, notwithstanding anything to the contrary herein, CyDex shall not (i) assign any of the Licensed Patents to an Affiliate or Third Party without assigning this Agreement in its entirety to such Third Party and (ii) assign this Agreement to any Affiliate or Third Party without assigning the Licensed Patents. Any assignment not in accordance with this Section 14.15 shall be void.

14.16 Third Party Beneficiaries. Except for the rights of Indemnified Parties pursuant to Section 10 hereof, and subject to Pfizer’s rights under Section 8.5 hereof, the terms and provisions of this Agreement are intended solely for the benefit of each party hereto and their respective successors or permitted assigns and it is not the intention of the parties to confer third-party beneficiary rights upon any other person, including without limitation Sublicensees. The enforcement of any obligation of CyDex under this Agreement shall only be pursued by Company or a Company Indemnitee, and not Sublicensees (unless otherwise a Company Indemnitee).

29

14.17 Remedies Cumulative; Right of Set-Off. Except as provided in Section 11, any enumeration of a party’s rights and remedies in this Agreement is not intended to be exclusive, and a party’s rights and remedies are intended to be cumulative to the extent permitted by law and include any rights and remedies authorized in law or in equity. Notwithstanding anything to the contrary in this Agreement, Company shall not have a right to set-off any royalties, milestones or other amount due to CyDex under this Agreement and/or the Supply Agreement against any damages incurred by Company for a breach by CyDex of this Agreement and/or the Supply Agreement.

14.18 Interpretation. The language used in this Agreement is the language chosen by the parties to express their mutual intent, and no provision of this Agreement shall be interpreted for or against any party because that party or its attorney drafted the provision.

14.19 Headings. The descriptive headings of this Agreement are for convenience only, and shall be of no force or effect in construing or interpreting any of the provisions of this Agreement.

14.20 Construction. Any reference in this Agreement to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit shall be deemed to be a reference to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit, of or to, as the case may be, this Agreement, unless otherwise indicated. Unless the context of this Agreement otherwise requires, (a) words of any gender include each other gender, (b) words such as “herein”, “hereof”, and “hereunder” refer to this Agreement as a whole and not merely to the particular provision in which such words appear, (c) words using the singular shall include the plural, and vice versa, and (d) the words “include,” “includes” and “including” shall be deemed to be followed by the phrase “but not limited to”, “without limitation”, “inter alia” or words of similar import.
