a. Trade, cash and quantity discounts;

b. Discounts, refunds, rebates actually taken, chargebacks, retroactive price adjustments, and any other allowances which effectively reduce the net selling price (other than such which have already diminished the gross amount invoiced), including, without limitation, Medicaid, institutional and governmental rebates (other than such which have already diminished the gross amount invoiced);

In the event that a Licensed Product is commercialized in combination with one or more services and/or with one or more products which are themselves not Licensed Products for a mutually related price (e.g., buy one and get a discount on or a coupon for the other) or for a single price, the Net Sales for such Licensed Product shall be calculated by multiplying the gross amount invoiced for such combination sale by the fraction A/(A+B) where A is the fair market value of the Licensed Product and B is the fair market value of the other product(s) and/or service(s) in the combination sale, and allocating applicable “Net Sales” deductions in the same proportion. In the case of sale of a product combining (with the express written consent of CyDex) both of the Compound and another active pharmaceutical ingredient(s) prepared or combined with or formulated using Captisol, the Net Sales with respect to such multiple-ingredient product shall be calculated by multiplying the gross amount invoiced for such multiple-ingredient product sale by the fraction A/(A+B) where A is the fair market value of a (Compound-only) Licensed Product of such dosage and B is the fair market value of the multiple-ingredient product; provided, that it is understood that CyDex is entitled to withhold or condition such express written consent in its sole and absolute discretion, and that CyDex expressly reserves the right to condition the giving of any such express written consent on an agreement to vary the foregoing formula.

Provided that, and for avoidance of doubt: any pivotal trial, which could be or is used as one of the adequate and well-controlled trials for registration in any jurisdiction, whether or not formally denominated as a Phase III trial, shall be deemed to be a Pivotal Trial. Further for avoidance of doubt: if a clinical trial of a Licensed Product in human patients is not initially designed or presented as a Pivotal Trial but is later re-designed, re-presented or identified as or converted into a trial which could be or is used as one of the adequate and well-controlled trials for registration in any jurisdiction, it shall be deemed to be a Pivotal Trial as of the date of such re-design/re-presentation/identification/conversion, and if the first patient in such trial was dosed before the date of such re-design/re-presentation/identification/conversion, the Section 4.1(b)(B) milestone payment shall be payable upon such re-design/re-presentation/identification/conversion.

which has not lapsed or been revoked, abandoned or held unenforceable or invalid by a final decision of a court or governmental authority of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, and which has not been disclaimed, denied or admitted to be invalid, canceled or unenforceable by the owner through re-issue, re-examination or disclaimer, opposition procedure, nullity suit, or otherwise.

2. GRANT OF RIGHTS.

2.1 License Grants from CyDex to Company.

(a) Licensed Intellectual Property. 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, nontransferable (except with respect to the assignment provision in Section 14.13) license during the Term under the Licensed Intellectual Property, solely to develop, make, have made (pursuant to Section 2.4), use, sell, offer for sale, import and otherwise commercially exploit the Licensed Products in the Territory in and for the Field. (No license, exclusive or non-exclusive, is granted hereunder under the Licensed Intellectual Property, except to so develop, make, have made, use, sell, offer for sale, import or otherwise commercially exploit the Licensed Products in the Territory in and for the Field.) Notwithstanding the foregoing, to the extent that any Licensed Intellectual Property is 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 non-exclusive. 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 (including without limitation being potentially non-exclusive as a result of rights inhering in the United States Government under Chapter 18, Title 35 of the United States Code and regulations thereunder (or otherwise) by virtue of the fact that the licensed invention was funded by the United States Government) for intellectual property within the Licensed Intellectual Property, then CyDex shall pass on such rights to Company hereunder via a license that grants rights that are to such extent non-exclusive. It is understood that all references in this Agreement to “licenses” from CyDex to Company (and other forms of the word “license”) include applicable sublicenses from CyDex (as sublicensor) to Company (as sublicensee). Company may not develop, make, have made, use, sell, offer for sale, import or otherwise commercially exploit either the Licensed Intellectual Property or the Licensed Products for any other purposes than those specified in this Agreement. Company may not sublicense the Licensed Intellectual Property, except as expressly set forth in Sections 2.3 and 2.4 below.

(b) Scope of Licenses. CyDex grants no licenses or rights to use the Licensed Intellectual Property or any other intellectual property other than as expressly set forth herein or as may be expressly set forth in the Supply Agreement. CyDex grants no rights to Company to manufacture, have manufactured, 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 develop, make, have made (pursuant to Section 2.4), use, sell, offer for sale, import or otherwise commercially exploit the Licensed Products in the Territory in the Field. Without prejudice to the provisions of subsection (a) above, Company 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 a Captisol Improvement. CyDex shall not be liable to Company for violation of Company’s exclusive rights hereunder by Third 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 restricted in making sales of Captisol or licensing intellectual property rights to other persons and/or entities to the extent not expressly inconsistent with the licenses granted to Company under this Agreement and/or the covenants of CyDex in this Agreement, and (ii) CyDex does not warrant or indemnify Company or its Affiliates and Sublicensees against the Licensed Products infringing Third Party rights, except in cases where such infringement results from the incorporation of Captisol in said Licensed Products.

2.2 Grant of License from Company to CyDex. Company hereby grants to CyDex a non-exclusive, 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 or Competing Products during the Term). If during the Term any of (a) Company, (b) Affiliates to whom Company has provided sublicense rights under the licenses granted to Company by CyDex pursuant to Section 2.1, or (c) other 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 or are issued any patent thereupon, CyDex shall be deemed automatically to have a non-exclusive, 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 develop, make, have made, use, market, distribute, import, sell, offer for sale and otherwise commercialize Captisol and all products formulated with Captisol (other than the Licensed Products in the Field or Competing Products during the Term). Company shall provide prompt notice of any Captisol Improvement.

2.3 Sublicensing. Company shall have the right to grant sublicenses with terms consistent with those of this Agreement (collectively “Sublicenses”) under the licenses granted to Company pursuant to Section 2.1; provided, however, that the granting by Company of a Sublicense shall not relieve Company of any of its obligations hereunder. Any Sublicense shall automatically terminate upon the termination or expiration of this Agreement ***. Company shall ensure that all of its Sublicensees shall comply with the terms and conditions of this Agreement and the Supply Agreement, and Company shall be and remain fully responsible to CyDex for the compliance by such Sublicensees with the terms and conditions of this Agreement and the Supply Agreement as if such Sublicensees were Company hereunder and thereunder; provided, it is not required that a Sublicense include provisions for the Sublicensee to pay royalties or make milestone payments or other payments directly to Licensor or to provide royalty reports directly to Licensor. Company acknowledges that it has no right to, and agrees not to purport to, grant to anyone a sublicense under the Licensed Intellectual Property, other than Sublicenses compliant with the requirements of this Agreement for Sublicenses.

2.4 Contracting. To the extent necessary to engage any one or more Third Party

manufacturers (collectively “Contract Manufacturers”) 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 with terms consistent with those of 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 to CyDex for the compliance by such Contract Manufacturers with the terms and conditions of this Agreement as if such Contract Manufacturers were Company hereunder. Company shall not manufacture bulk Captisol (or contract the manufacture of bulk Captisol with a Contract Manufacturer).

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. All rights and licenses granted under or pursuant to this Agreement by Company to CyDex 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, as a licensee of such rights under this Agreement, CyDex shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code.

2.6 Compliance with Upstream Licenses. CyDex shall be solely responsible for paying directly to any and all Third Parties having rights in any of the Licensed Intellectual Property (each an “Upstream Licensor”) any royalties or other amounts due to such Upstream Licensors as a result of Company exercising its rights hereunder. 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 comply with the terms of its agreements with such Upstream Licensors throughout the Term. Furthermore, CyDex covenants 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, neither CyDex nor any of its Affiliates shall directly themselves, nor provide any Third Party any assistance whatsoever, nor grant any Third Party any title, right, claim, interest or license under, in or to any of the Licensed Intellectual Property to, research, develop, modify, make, have made, import, export, use, promote, market, distribute, package, offer for sale, sell, or otherwise commercially exploit Licensed Products or any Competing Products.

(b) During the Term, neither CyDex nor any of its Affiliates shall (other than at Company’s express written request) supply Captisol to any Third Party which it knows or should know will use it for a Licensed Product or a Competing Product. If during the Term, any such Third Party utilizes such Captisol (supplied by CyDex or any of its Affiliates) in a Licensed Product or Competing Product, CyDex shall immediately cease and cause its Affiliates and any other Third Party to

immediately cease supplying Captisol 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.

(c) During the Term, neither CyDex nor any of its Affiliates shall xxx or threaten to xxx, or take any similar action against, or aid, abet or enable any Third Party to xxx, threaten to xxx or take any similar action against, Company, or any Sublicensees, or any of their respective Affiliates, or any customers or end-users of any Licensed Products, claiming that the development, manufacture, use, sale, offer for sale or importation of any Licensed Product infringes any Captisol-related patents or patent applications owned, licensed, sublicensed or otherwise controlled by, now or in the future, CyDex or any of its Affiliates.

3. MANUFACTURE AND SUPPLY OF CAPTISOL.

The provisions of the Supply Agreement shall govern the manufacture and supply of Captisol® sulfobutylether b (beta) cyclodextrin, sodium salt for use in Company’s (and its Affiliates’ and their Sublicensees’) preparation, formulation and production of the Licensed Products, both before and after Marketing Approval (the “Licensed Products Related Uses”). Company acknowledges and agrees that CyDex is, during the term of the Supply Agreement, the exclusive manufacturer of sulfobutylether b (beta) cyclodextrin, sodium salt for Company and its Affiliates and Sublicensees for the aforementioned Licensed Products Related Uses. Nothing set forth herein shall be deemed to grant Company or its Affiliates or Sublicensees the right to manufacture Captisol nor the right to contract the manufacture of Captisol to a Third Party, except pursuant to any express provisions of the Supply Agreement. It is understood that it shall be Company’s and its Affiliates’ responsibility to obtain, at Company’s and its Affiliates’ sole expense and from sources other than CyDex, all materials (including all quantities of the Compound, but excluding sulfobutylether b (beta) cyclodextrin, sodium salt) needed by Company and its Affiliates for the Licensed Products Related Uses — it being further understood, of course, that Company is to obtain at Company’s sole expense and solely from CyDex (pursuant to the Supply Agreement) all sulfobutylether b (beta) cyclodextrin, sodium salt needed by Company and its Affiliates and Sublicensees for the Licensed Products Related Uses. It is of the essence that the only Captisol used in or for any Licensed Product shall be Captisol supplied by CyDex under the Supply Agreement or previously supplied by CyDex under the July 2014 Agreement, and Company hereby covenants and agrees that Company and its Affiliates and Sublicensees shall not use in or for any Licensed Product any other Captisol other than Captisol® and further covenants and agrees that Company and its Affiliates and Sublicensees shall not use in or for any Licensed Product any Captisol® obtained other than directly from CyDex under the Supply Agreement or previously under the July 2014 Agreement.

4. COMPENSATION.

4.1 Payments and Royalties for Licenses.

(a) One-Time Fee. Company shall forthwith (but in no event later than 10 days after delivery of the corresponding invoice sent by CyDex after the Effective Date) pay to CyDex a non-refundable, non-creditable, one-time cash fee of $*** in partial consideration of the rights granted to Company under this Agreement.

(b) Milestone Payments. Within 30 days following the achievement of each and any milestone event listed below, Company shall, in further consideration of the rights granted Company hereunder, provide written notice to CyDex of the achievement of such milestone event, accompanied by payment to CyDex of the applicable non-refundable cash milestone fee listed next to such event.

	MILESTONE	MILESTONE PAYMENT
(A)	***	$	***
(B)	***	$	***
(C)	***	$	***
(D)	***	$	***

Upon achievement of Milestone (B), (C) or (D) with regard to a Licensed Product, the Milestone (A) shall be deemed to be thereby achieved and if such Milestone (A) milestone payment has not previously been paid, it shall thereupon also be paid, forthwith. For clarity, each Milestone shall be paid only once.

(c) Royalties.

(i) In addition to the amounts payable pursuant to Section 4.1(a) and Section 4.1(b) above, Company shall for all Net Sales within the Term pay to CyDex, on a calendar quarterly basis, ***% royalties on the first $*** of worldwide annual Net Sales, and ***% royalties on the portion of worldwide annual Net Sales which exceeds $***. Notwithstanding the foregoing, as a royalty-rate step-down, for Net Sales (in a country), during the Term, of a Licensed Product which are made after expiry of the last-to-expire Licensed Patent containing a Valid Claim that would in the absence of the license granted herein be infringed by the use, manufacture or sale of such Licensed Product in such country or by the importation of such Licensed Product into such country, Company shall instead pay to CyDex, on a calendar quarterly basis, ***% royalties on the first $*** of worldwide annual Net Sales, and ***% royalties on the portion of worldwide annual Net Sales which exceeds $***.

(ii) Unless this Agreement is earlier terminated pursuant to Section 13, royalties shall be payable, on a Licensed Product-by-Licensed Product and country-by-country basis, during the period from the First Commercial Sale of a given Licensed Product in a given country until the later of (a) expiry of the last-to-expire Licensed Patent containing a Valid Claim in such country that would in the absence of the license granted herein be infringed by the use, manufacture or sale of such Licensed Product in such country or by the importation of such Licensed Product into such country; or (b) the 10th anniversary of the First Commercial Sale of such Licensed Product in such country.

(iii) All royalties payable to CyDex pursuant to Section 4.1(c) shall be paid on a quarterly basis. These royalties shall be paid together with and in strict compliance with the amounts defined in the final written royalty report sent by Company for the preceding calendar quarter, as set forth in Section 5.2 below. Within 75 calendar days after the conclusion of its 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 in good faith to be correct; provided however, the lapse of

such 75-day period shall not impact the right of a Party to credit or recover any overpayments or underpayments discovered during an audit under Section 5.3.

(iv) 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 license under the Licensed Intellectual Property, 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 and under the Supply Agreement exclude and shall, as far as is legally possible, be paid in full to CyDex without reduction for all applicable 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 and under the Supply Agreement. The Parties agree to cooperate with one another and use 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 and under the Supply Agreement. To the extent Company is required to withhold taxes on any payment to CyDex under this Agreement or under the Supply Agreement, 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 in due time 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, and Company shall utilize such forms to such effect. 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 and under the Supply Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax. CyDex shall indemnify and hold Company harmless from and against any penalties, interest or other tax liability arising from any failure by Company (at the express request of CyDex) to withhold or from any Company reduction (at the express request of CyDex) in its withholding.

4.3 Payments. Accrual and payment of interest shall not be deemed to excuse or cure breaches of contract arising from late payment or nonpayment. Cumulative with and not exclusive of any and all other available remedies, payments that are not made when due hereunder, and which are not otherwise subject to a good faith dispute, shall accrue interest, from due date until paid, at an annual rate equal to the prime rate, as reported in The Wall Street Journal, Eastern United States Edition, on the date such payment is due, plus an additional 200 basis points (2%). All amounts due hereunder are stated in and shall be paid in United States Dollars.

5. RECORDS; REPORTS; AUDIT.

5.1 Records. During the Term and until the end of the third calendar year after the calendar year during which the Term ends, Company shall, and shall require its Affiliates and Sublicensees to, maintain accurate books and records relating to Net Sales. Without limitation, for three years after the calendar year in which each respective sale of a Licensed Product (whether covered by a Valid Claim

or not) occurs, Company shall keep (and shall ensure that its Affiliates and Sublicensees shall keep) complete and accurate records of such sale in sufficient detail to confirm the accuracy of the royalty calculations hereunder.

Within 25 calendar days after the conclusion of each calendar quarter after a First Commercial Sale and after the conclusion of each successive calendar quarter until the end of the first full calendar quarter after the end of the Term, Company shall deliver to CyDex a verbal or written, non-binding initial estimate of Net Sales and royalties due to CyDex, followed by (within 45 calendar days following the conclusion of each calendar quarter after the First Commercial Sale of the relevant Licensed Product in any country and after the conclusion of each successive calendar quarter until the end of the first full calendar quarter after the end of the Term) a final written royalty report. Each final written royalty report shall provide, on a Licensed Product-by-Licensed Product (and specifying whether covered by a Valid Claim or not, as applicable) and country-by-country basis, (a) gross invoiced (or otherwise charged) amounts of sales, by Company and its Affiliates and Sublicensees, of Licensed Products subject to royalty payments for such calendar quarter, (b) amounts deducted by category (following the definition of Net Sales) from such gross invoiced amounts to calculate Net Sales, (c) Net Sales subject to royalty payments for such calendar quarter and calendar year to date, (d) exclusions pursuant to Section 4.1(c)(i), and (e) the corresponding royalty amount due hereunder. Such reports shall be deemed “Confidential Information” of Company and shall be subject to the obligations of Section 8 of this Agreement.

5.3 Audit. Upon at least 30 days’ advance written notice by CyDex, Company shall permit, shall cause its Affiliates and Sublicensees to permit, an independent certified public accounting firm of nationally recognized standing selected by CyDex (who has not been engaged by CyDex to provide services in any other capacity at any time during the three-year period before such selection), and reasonably acceptable to Company or such Affiliate or Sublicensee, to have access to and to review, during normal business hours on business days upon reasonable prior written notice, the applicable records of Company and its Affiliates or Sublicensees to verify the accuracy of the royalty payments under this Section 5. Such review may cover: (a) the records for sales made in any calendar year ending not more than three years before the date of such request, and (b) only those periods that have not been subject to a prior audit. Except as described hereafter, all such audits shall be conducted at the expense of CyDex. Such audits shall be conducted not more than once in each calendar year and not more than once for each audited period. In the event such accountant concludes that additional payments of any kind as required by this Agreement were owed to CyDex during such period, the additional amounts shall be paid within 30 days after the date of the corresponding invoice sent by CyDex and delivered to Company with copy of the aforementioned accountant’s written report so concluding, unless Company disputes the results of such audit in accordance with Section 14.3. The fees charged by such accountant shall be paid by CyDex, unless the audit discloses that the amounts payable by Company for the audited period are more than *** of the amounts actually paid for such period, in which case Company shall pay the reasonable fees and expenses charged by the accountant for such audit (upon resolution of any dispute initiated by either Party pursuant to Section 14.3 with respect to the same). In the event such accountant concludes that there was an overpayment by Company to CyDex during such period, at Company’s option, the overpayment shall be paid by CyDex to Company within 30 days after the date of the of the corresponding invoice sent by Company to CyDex, unless CyDex disputes the results of such audit in accordance with Section 14.3. CyDex shall cause the independent certified public accountant to keep confidential any information obtained during such inspection in accordance with the provisions set forth in Section 8 hereof and shall report to

CyDex only the amounts of (y) Net Sales that give rise to royalties and (z) royalties payments due and payable. The Parties agree that all information subject to review under this Section 5.3 or under any Sublicense agreement is the Confidential Information of Company.

Company shall also provide updates regarding any material changes to the expected completion of any such milestones outlined in the annual report or any change that may materially affect the Supply Agreement or orders placed thereunder during such calendar year. The Parties agree that the aforementioned written report is the Confidential Information of Company and shall be subject to the obligations of Section 8 of this Agreement.

8. CONFIDENTIALITY.

8.1 Definition. Company and CyDex each recognizes that during the Term, it may be necessary or advisable for a Party (the “Disclosing Party”) to provide Confidential Information (as defined herein) to the other Party (the “Receiving Party”). Neither Company nor CyDex shall disclose or 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 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 after such oral disclosure, including but not limited to product specifications, data, know-how, formulations, product concepts, sample materials, study results, analyses, protocols, business and technical information, financial data, batch records, inventions, works of authorship, Know-How, trade secrets, processes, techniques, algorithms, programs, designs, drawings, and any other information related to a Party’s present or future products, technology, 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 Sublicensees’ and/or Affiliates’) officers, employees, consultants, attorneys, accountants, bankers, Contract Manufacturers, lenders and agents only if and to the extent necessary to carry out their respective responsibilities under this Agreement or the Supply Agreement, or in accordance with the exercise of their rights under this Agreement or the Supply Agreement, and such disclosure shall be limited to the maximum extent possible consistent with such responsibilities and rights and provided that such persons or entities are under a written obligation of confidentiality at least as restrictive as this Section 8. Except as set forth in the foregoing sentence, neither Party shall disclose Confidential Information of the other to any person or entity without the other’s prior written consent. In all events, however, any and all disclosure to any such persons or entities shall also be pursuant to the terms of a non-disclosure/nonuse agreement no less restrictive than this Section 8 (or, in the case of attorneys, to a duty and obligation of nondisclosure/nonuse

pursuant to the applicable rules of the profession). The Party which disclosed Confidential Information of the other to any such team member or Third Party (or to any such Affiliate or Sublicensee) shall be responsible and liable for any disclosure or use by such team member or Third Party, Affiliate or Sublicensee (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 promptly return or destroy (at Disclosing Party’s discretion) all the Confidential Information disclosed to the other Party pursuant to this Agreement, including all copies, embodiments, reflections, analyses and extracts of documents, except for (a) one archival copy (and such electronic copies that exist as part of the Party’s computer systems, network storage systems and electronic backup systems) of such materials solely to be able to monitor its obligations that survive under this Agreement and (b) any archival copy that this Party is required to keep by applicable regulations.

8.3 Exceptions. The non-use and non-disclosure obligations set forth in this Section 8 shall survive the expiration or earlier termination of this Agreement. The non-use and non-disclosure obligations set forth in this Section 8 shall not apply to any Confidential Information, or portion thereof, that was first disclosed by the Disclosing Party to the Receiving Party after the expiration or earlier termination of this Agreement or 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 and or without violation of any duty of confidentiality of the Receiving Party or its disclosees;

(c) at the time of disclosure is already in the Receiving Party’s possession with no duty of confidentiality;

(d) is rightfully received by the Receiving Party from an independent Third Party without obligation of confidentiality; provided, however, that to the Receiving Party’s best knowledge, such information was not obtained by said Third Party, directly or indirectly, from the Disclosing Party; or

(e) is independently developed by or expressly for the Receiving Party, in either case solely by personnel without any access to or use of the Disclosing Party’s information as shown by Receiving Party’s competent, contemporaneous written evidence.

In addition, in the event that the Receiving Party or any of its Representatives is required by law, rule, regulation, court order or in any regulatory, judicial or governmental process having jurisdiction over the Receiving Party to disclose the Confidential Information, the Receiving Party hereby agrees to notify the Disclosing Party of the request or requirement immediately and to make a reasonable effort to obtain, or to assist the Disclosing Party in obtaining, confidential treatment or a protective order or any other reasonable measure preventing or limiting the disclosure (to the greatest

possible extent and for the longest possible period), 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, which the Disclosing Party deems necessary to protect the confidentiality of the Confidential Information (or as much as possible of the Confidential Information). In any event, should the Receiving Party be required by such compulsion to in the end disclose Confidential Information to the requiring authority (and, if so required thereby, to the public), (x) the Receiving Party hereby agrees to take reasonable steps to seek such confidential treatment for the Confidential Information (or as much as possible of the Confidential Information); (y) the Receiving Party may provide the Confidential Information to the appropriate requiring authority (and, if so required thereby, to the public) as ultimately so compelled without such disclosure being deemed a violation of this Agreement; and (z) such disclosure to the requiring authority as ultimately so compelled shall not deprive the disclosed information of Confidential Information status for any other purposes of this Agreement.

8.4 Third Party Information.

(a) Company is generally informed 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 either included in the DMF or is specifically identified in a prior written notice by CyDex to Company as being part of CyDex’s Confidential Information disclosed to Company hereunder, 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) The Parties acknowledge that the defined term “Confidential Information” shall include not only a Disclosing Party’s own Confidential Information but also Confidential Information of a Third Party or the Disclosing Party’s Affiliates which is in the possession of the Disclosing Party. 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.

8.5 Public Announcements. The Parties shall mutually agree on any press release to be issued upon execution of this Agreement; such release may include a high-level description of the royalty and milestone payment obligations 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, conditioned 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 sufficiently in advance of the scheduled disclosure to afford such other Party a reasonable opportunity to review and comment upon the proposed text and the timing of such disclosure, and shall consider all reasonable comments of the other Party regarding such disclosure. (Provided, that neither Party shall use the trademark 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, except as may be required by law or required by the rules of an applicable US national securities exchange or except with the prior

express written permission of such other Party, such permission not to be unreasonably withheld, conditioned or delayed.) Notwithstanding the above, once a public disclosure has been made, either Party shall be free to disclose to Third Parties any information contained in said public disclosure, without further pre-review or pre-approval.

Company shall defend, indemnify and hold CyDex and its Affiliates, and each of their respective directors, officers, managers, employees and agents (collectively, the “CyDex Indemnitees”), harmless from and against any and all Losses incurred by the CyDex Indemnitees as a result of any Claim by a Third Party, to the extent such Losses arise out of: (a) Company’s breach of this Agreement or the Supply Agreement, including without limitation any of its covenants, representations and warranties herein or therein; (b) any breach or violation of any applicable law, regulation or court order by Company, its Affiliates, sublicensees or contractors, or any of their respective directors, officers, managers, employees or agents, in connection with the activities contemplated by this Agreement or the Supply Agreement including but not limited to those listed in subsections (c), (d) and (e) below, (c) any Study conducted by or on behalf of Company; (d) the research, development, manufacture, use, handling, promotion, marketing, distribution, importation, sale or offering for sale of Licensed Products by Company, its Affiliates, Sublicensees, Contract Manufacturers, distributors or agents (for clarity, such terms shall not include CyDex in any event); (e) interactions and communications by Company, its Affiliates, Sublicensees, distributors or agents with governmental authorities, physicians or other Third Parties relating to Licensed Products and/or Captisol; (f) the grossly negligent or willful misconduct of Company or its Affiliates, Sublicensees, Contract Manufacturers, distributors or agents or any of their respective directors, officers, managers, employees or agents; or (g) actual or alleged infringement of a Third Party’s intellectual property rights in the making, having made, using, selling, offering for sale and importing of Licensed Products, but only to the extent that any such infringement Claim is unrelated to Captisol or the Licensed Intellectual Property; and, for each of subsections (a)-(g), all except to the extent that such Losses are primarily caused by a CyDex Indemnitee’s breach of applicable law, this Agreement or the Supply Agreement, gross negligence or willful misconduct.

10.3 Expenses. The indemnification obligation of each Party under this Section 10 shall include, where applicable, reasonable attorney costs and expenses incurred by the other Party (or an applicable Company Indemnitee or CyDex Indemnitee) to successfully enforce any provision of this Section 10.

10.4 Procedure. The Party or other Indemnitee intending to claim indemnification under this Section 10 (an “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) of any Claim in respect of which the Indemnified Party intends to claim such indemnification (provided, that no delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any liability or obligation under this Agreement except to the extent the Indemnifying Party has suffered actual prejudice directly caused by the delay or other deficiency), and the Indemnifying Party shall assume the defense thereof (with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party) whether or not such Claim is rightfully brought; provided, however, that an Indemnified Party shall have the right to retain its own counsel and to participate in the defense thereof, with the fees and expenses to be paid by the Indemnified Party, unless a representation of both the Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate due to the actual or potential differing interests between them, in which case the Indemnifying Party shall pay (as incurred and on demand) the reasonable fees and expenses of counsel retained by the Indemnified Party and all other expenses of investigation and litigation. (Provided, that in no event shall the Indemnifying Party be required to pay for more than one separate counsel no matter the number or circumstances of all Indemnified Parties.) If the Indemnifying Party shall fail to timely assume the defense of and reasonably defend such Claim, the Indemnified Party shall have the right to retain or assume control of such defense and the Indemnifying Party shall pay (as incurred and on demand) the reasonable fees and expenses of counsel retained by the Indemnified Party and all other expenses of investigation and litigation. The Indemnifying Party shall not be liable for the indemnification of any Claim settled (or resolved by consent to the entry of judgment) without the written consent of the Indemnifying Party. Also, if the Indemnifying Party shall control the defense of any such Claim, the Indemnifying Party shall have the right to settle such Claim; provided, that the Indemnifying Party shall obtain the prior written consent (which shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Party before entering into any settlement of (or resolving by consent to the entry of judgment upon) such Claim unless (a) there is no finding or admission of any violation of law or any violation of the rights of any person or entity by an Indemnified Party, no requirement that the Indemnified Party admit fault or culpability, and no adverse effect on any other claims that may be made by or against the Indemnified Party and (b) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement does not require the Indemnified Party to take (or refrain from taking) any action.

Regardless of who controls the defense, the other Party hereto shall reasonably cooperate in the defense as may be requested. Without limitation, the Party hereto which is not the Indemnifying Party, and its directors, officers, managers, employees, agents and advisers, and the Indemnified Party, and its directors, officers, managers, employees, agents and advisers, shall cooperate fully with the Indemnifying Party and its legal representatives in the investigations of any Claim.

10.5 Other Scenarios. Subject to Section 11, this Section 10 shall not be construed to suggest that a Party has no remedy other than under this Section 10 (or does not have any particular remedy) for Losses and diminutions in value which arise from breaches of this Agreement or of the

Supply Agreement but which are not incurred as a result of a Claim.

11. LIMITATION OF LIABILITY.

EXCEPT FOR (a) INDEMNIFICATION OBLIGATIONS IN CONNECTION WITH THIRD PARTY CLAIMS PURSUANT TO SECTION 10 HEREOF, AND/OR (b) (DAMAGES ARISING FROM OR IN CONNECTION WITH A BREACH BY CYDEX OF ITS CONFIDENTIALITY OBLIGATIONS HEREUNDER, AND/OR (c) INTENTIONAL MISCONDUCT OR WILLFUL AND KNOWING BREACH, AND/OR (d) PROVISIONS OF THIS AGREEMENT AND THE SUPPLY AGREEMENT WHICH EXPRESSLY REQUIRE PAYMENTS, THE TOTAL AGGREGATE LIABILITY OF CYDEX FOR DAMAGES UNDER THIS AGREEMENT AND THE SUPPLY AGREEMENT (TOGETHER) IS LIMITED TO A MAXIMUM AMOUNT OF ***.

NO ACTION, REGARDLESS OF FORM, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SUPPLY AGREEMENT MAY BE BROUGHT BY EITHER PARTY MORE THAN TWO YEARS AFTER SUCH PARTY HAS KNOWLEDGE OF BOTH THE OCCURRENCE AND THE CONSEQUENCES OF SAID OCCURRENCE THAT GAVE RISE TO THE CAUSE OF ACTION OR AFTER EXPIRATION OF THE APPLICABLE STATUTORY LIMITATIONS PERIOD, WHICHEVER IS SOONER.

CyDex shall have the 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; provided, that CyDex shall reimburse Company for any such costs incurred by Company therefor. Before commencing such an action, CyDex shall consult with Company and give consideration to Company’s recommendations regarding the proposed action. Company shall provide to CyDex reasonable assistance in such enforcement, at CyDex’s request and expense. CyDex shall control the direction of and any settlement of any such action.

(b) Company and/or any of its Affiliates shall control the defense of any litigation mentioned in subsection (a) above, at their own expense and by counsel of their own choice, and CyDex agrees that it will furnish to Company and/or any of Company Affiliates, upon request, all evidence and information in its possession relating to or reasonably necessary for such defense. Provided that, to the extent the litigation concerns (in whole or in part) Captisol, CyDex shall have the right, at its

own expense, to be represented in the legal proceedings by counsel of its own choice, and Company and its Affiliates and their counsels will reasonably cooperate with CyDex and its counsel in strategizing, preparing and presenting the defense.

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 (a) the final expiration of the last-to-expire of the Licensed Patents that would in the absence of the license granted herein be infringed by the use, manufacture or sale of any Licensed Product in the applicable country or by the importation of such Licensed Product into such country or (b) the 10th anniversary of the First Commercial Sale of any Licensed Product, in each case in the applicable country. In a country (if any) where no Licensed Patent containing a Valid Claim has ever existed nor ever exists, the Term means the period from the First Commercial Sale of a Licensed Product in such country until the 10th anniversary of such First Commercial Sale of a Licensed Product in such country. The Parties confirm that subject to this 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.

13.2 Termination of the Supply Agreement. If the Supply Agreement is terminated in accordance with its terms (except a termination of the Supply Agreement by CyDex for convenience or by Company for CyDex’s material breach), CyDex shall have the right to terminate this Agreement with five days’ prior written notice to Company.

13.3 Termination for Breach. If either Party should materially breach or violate or fail to perform any material term or covenant of this Agreement or the Supply Agreement, then the other Party may give written notice of such default to the first Party. If such Party should fail to cure such default within 60 days (or 15 days with respect to any payment obligation) of the date of such notice, the other Party shall have the right to terminate this Agreement by a second written notice (a “Notice of Termination”) to the first Party. If Notice of Termination is sent to such first Party, this Agreement shall automatically terminate on the effective date of such notice. The Parties agree that any failure by Company to pay when due (subject to the 15-day cure period) 100% of any amount of money owing from Company to CyDex as is not disputed in good faith by Company (or, if some portion of the amount of money owing from Company to CyDex is not disputed in good faith by Company and the remaining portion is disputed in good faith by Company, 100% of the portion which is not disputed in good faith by Company) shall conclusively be deemed to constitute a “material” breach.

13.4 Termination for Bankruptcy. To the extent permitted under applicable laws, either Party may terminate this Agreement in its entirety if, at any time, the other Party: (a) files in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party or of its assets, (b) is served with an involuntary petition against it, filed in any bankruptcy or insolvency proceeding, and such petition is not dismissed within 45 days after the filing thereof, (c) commences any dissolution or liquidation, or (d) makes a general assignment for the benefit of its creditors.

13.5 Termination for Convenience. Company may terminate this Agreement at any time upon *** days’ prior written notice to CyDex.

13.6 Survival. Notwithstanding any other provisions of this Agreement, any liability or obligation of either Party to the other (or to the other’s Indemnitees) for or arising from 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, (a) royalties for all Licensed Products sold by Company, its Affiliates or Sublicensees, (b) milestone payments for milestones achieved, or (c) sums due in respect of Captisol shipped, in each case before termination or expiration of this Agreement, or (d) the Section 4.1(a) *** payment.

13.7 Effect of Termination.

(a) Following the termination 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, except for (i) one archival copy (and such electronic copies that exist as part of the Receiving Party’s computer systems, network storage systems and electronic backup systems) of such materials solely to be able to monitor its obligations that survive under this Agreement and (ii) any archival copy that the Receiving Party is required to keep by applicable law or regulations.

(b) The licenses granted in Section 2.1 shall become perpetual, fully paid-up and royalty-free as to all countries of the Territory if and when (i) the Company terminates this Agreement under Section 13.3 for CyDex’s breach and (ii) either (A) CyDex expressly acquiesces to such termination in writing or (B) the rightfulness of such termination has been confirmed by a final judgment of the appropriate federal or California state court pursuant to Section 14.3 and no further appeal from such court’s final judgment is possible, either because the applicable time for filing any further appeal has expired or because an appellate court of final jurisdiction has affirmed such final judgment.

(c) 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.

14. GENERAL PROVISIONS.

14.1 Relationship of Parties. Each of the Parties hereto is an independent contractor and nothing in this Agreement is intended or shall be deemed to constitute a partnership, agency, employer-employee or joint venture relationship between the Parties. Neither Party shall have the right to, and each Party agrees not to purport to, incur any debts or make any commitments or contracts for the

other. During the Term of this Agreement and for a period of one year thereafter, Company shall not solicit, induce, encourage or attempt to induce or encourage any employee of CyDex to terminate his or her employment with 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 Dispute Resolution.

(a) Elevation of Issues for Resolution. In the event of any dispute or disagreement between the Parties in connection with this Agreement, the construction hereof, or the rights, duties or liabilities of either Party hereunder (each, a “Dispute”), the Parties shall endeavor to resolve such Dispute in accordance with the terms of this Section 14.3(a). The Parties shall promptly refer such matter to, as appropriate, the Parties’ respective Designated Executives, who shall use good faith efforts to resolve such matter. If agreement on a mutually acceptable resolution of such Dispute is not reached by the Designated Executives within 15 business days after a Party gives written notice to refer such Dispute to them, then such Dispute shall be subject to resolution in accordance with Section 14.3(b).

(b) Dispute Settlement. If any Dispute is not resolved by mutual agreement of the Parties in accordance with Section 14.3(a) above within 15 business days of a Party giving notice to refer such Dispute to the Parties’ Designated Executives under Section 14.3(a), then either Party may submit such Dispute (and any related claims or other disputes arising out of or relating hereto or to the transactions contemplated hereby or to the inducement of any Party to enter herein or therein, whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise) for final settlement by the competent federal or state court located in the county of San Diego, California, notwithstanding plurality of defendants, summary proceedings or impleader. Each Party hereby irrevocably consents to the personal jurisdiction of such federal or California state court and agrees that venue is appropriate in such court, and agrees not to assert that such court is an inconvenient forum. The Parties agree that the jurisdiction of such court located in the county of San Diego, California shall be exclusive.

(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 seek interim equitable relief. Neither Party shall commence any court proceeding or action against the other to resolve any dispute, except for such interim injunctive relief or upon compliance with Section 14.3(a) and Section 14.3(b).

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 instruments 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 or in breach 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. The corresponding obligations of the other Party shall be suspended to the same extent. 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, 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 reasonable commercial 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.

14.7 Notices. Any notice, request, approval or consent required or permitted to be given under this Agreement or the Supply Agreement shall be in writing and shall be deemed to have been sufficiently given if and only if delivered in person, by email or by internationally recognized overnight courier service to the Party to which it is directed at its physical or email address shown below or such other physical or email address as such Party shall have last given by such written notice to the other Party in accordance with this Section 14.7:

If sent by internationally recognized overnight courier, the date on which such notice, request, approval or consent shall be deemed delivered is the next business day after the date of deposit with such courier (by the courier’s stated time for enabling next-business-day delivery), and if delivered after such stated time shall be deemed to be the second business day after the date of deposit.

14.8 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 or country). The Parties agree that the United Nations Convention on Contracts for the International Sale of Goods shall be inapplicable to this Agreement and the Supply Agreement and transactions hereunder and thereunder.

14.9 Entire Agreement. 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. Notwithstanding the foregoing, it is understood and agreed that neither Party shall be relieved from any liability for any past breach of any previous written agreements. In addition, any confidential information which was disclosed under such previous written agreements shall remain confidential and shall be subject to the nondisclosure and nonuse provisions set forth in Section 8 of this Agreement. Neither Party has made any promises, representations, warranties, covenants, or undertakings, other than those expressly set forth herein and in the Supply Agreement, to induce the other Party to execute and deliver this Agreement and the Supply Agreement, and each Party acknowledges that it has not executed or delivered this Agreement and the Supply Agreement in reliance upon any such promise, representation, or warranty, covenant or undertaking not contained herein or in the Supply Agreement.

(Specifically with regard to the July 2014 Agreement (which the parties hereby terminate with immediate effect), it is further agreed that any Confidential Information disclosed thereunder shall be deemed to have been disclosed under and shall be governed by this Agreement, the performance of any Studies contemplated thereby shall hereafter be subject to and governed by this Agreement, and any Captisol purchased thereunder shall be deemed to have been purchased and delivered under and shall be governed by this Agreement and the Supply Agreement (except that the price paid for any Captisol ordered thereunder before 2017 shall not be retroactively adjusted). In addition, the Parties agree that all Confidential Information heretofore disclosed under the Mutual Non-Disclosure Agreement entered into in 2014 by Company and CyDex’s parent company Ligand Pharmaceuticals Incorporated shall be deemed to have been disclosed (by or on behalf of CyDex, or to CyDex or to a person or entity on behalf of CyDex) under and shall be governed by this Agreement, and all Confidential Information hereafter disclosed shall be deemed to be disclosed under and shall be governed by this Agreement rather than under and by such Mutual Non-Disclosure Agreement.)

14.10 Amendment. This Agreement may not be amended unless agreed to in writing by

both Parties.

14.11 Waiver. 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 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. 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.

14.12 Severability. This Agreement is severable. When possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law; but 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 make a good faith effort 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).

14.13 Assignment. 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, whether by way of merger, exclusive-license or sale of all or substantially all the assets to which this Agreement relates, sale of stock or otherwise, without prior written consent. Provided, however, that as a condition to any such permitted assignment hereunder, the assignor must guarantee the performance of the terms and obligations of this Agreement by any assignee, and 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. Except as provided herein, 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, conditioned or delayed. Any assignment not in accordance with this Section 14.13 shall be void.

14.14 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.

14.15 No Implied License. No right or license is granted to either Party hereunder by implication, estoppel, or otherwise to any Know-How, patent or other intellectual property right now or hereafter owned or controlled by such Party or its Affiliates, except by an express license granted hereunder.

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 8.4 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 by Sublicensees (unless otherwise a Company Indemnitee).

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 or in the Supply Agreement, Company shall not have a right to set-off any royalties, milestone payments or other amounts 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 Equitable Relief. Each Party recognizes that the covenants and agreements herein and their continued performance as set forth in this Agreement are necessary and critical to protect the legitimate interests of the other Party, that the other Party would not have entered into this Agreement in the absence of such covenants and agreements and the assurance of continued performance as set forth in this Agreement, and that a Party’s breach or threatened breach of such covenants and agreements may cause the opposed Party irreparable harm and significant injury, the amount of which will be extremely difficult to estimate and ascertain, thus potentially making any remedy at law or in damages inadequate. Therefore, each Party agrees that an opposed Party shall be entitled to seek specific performance, an order restraining any breach or threatened breach of Section 8 and any or all other provisions of this Agreement, and any other equitable relief (including but not limited to temporary, preliminary and/or permanent injunctive relief), all without need to post any bond or security, and (except as provided in Section 11) in addition to and not exclusive of any other remedy available to such other Party at law or in equity.

14.19 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.

14.20 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.

14.21 Construction. Any reference in this Agreement to an Article, Section, subsection, paragraph, clause or Exhibit shall be deemed to be a reference to an Article, Section, subsection, paragraph, clause 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.

14.22 Counterparts. This Agreement may be executed and delivered in counterparts (portable document format (.pdf)/electronic transmission included), each of which shall constitute an original document, but both of which shall constitute one and the same instrument.
