The contents of each such submission shall be deemed to be Confidential Information of Sage, subject to the terms and provisions of Section 8 below. Sage shall promptly inform CyDex of meetings with the FDA (or other regulatory agencies in the Territory) regarding the Licensed Product.

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 that Sage shall be entitled to in good faith and with full regard for CyDex’s interests and concerns make the final determination as to the contents of any such materials.

7.2 Material Safety. CyDex shall provide Sage, 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.

Probe Study Product-related or Licensed Product-related, which occurs or worsens following administration of Captisol, Probe Study Product or Licensed Product. Sage shall provide CyDex with copies of

***Text Omitted and Filed Separately with the Securities and Exchange Commission Confidential Treatment Requested Under 17 C.F.R. Sections 200.80(b)(4) and 230.406

all reports of any such adverse event which is serious (any such adverse event involving Captisol, the Probe Study Product 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 Sage has reason to believe are associated with Captisol within 10 business days following (i) Sage’s submission of any such report to any regulatory agency, or (ii) receipt from Sage’s Sublicensee, co-marketer or distributor of any such report to any regulatory agency.

The findings of such independent laboratory shall be binding upon the parties. The cost of the independent quality control laboratory shall be borne by the party whose results are shown by such laboratory to have been incorrect. If (i) Sage and CyDex agree in writing that it is appropriate to recall any Licensed Product, or (ii) the FDA requires the recall of any Licensed Product, and in either case, to the extent that such recall is due to issues relating to Captisol, then CyDex agrees, upon substantiation thereof, to bear a proportionate share (based on the extent to which the recall was caused by issues relating to Captisol) of the reasonable direct costs associated with said recall, including a proportionate share of the actual cost of conducting the recall in accordance with the recall guidelines of the applicable governmental authority, including without limitation, a proportionate share of the cost of the Licensed Product subject to the recall. Sage shall in all events be responsible for conducting any such recalls with respect to the Licensed Product and shall maintain records of all sales of Licensed Product and customers sufficient to adequately administer any such recall, for a period of five years after termination of this Agreement.

Sage and CyDex each recognizes that, during the Term or the term of the Old Agreement, it may be (or was) 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 will be governed by the provisions of this Section 8. Neither Sage nor CyDex shall use the other’s Confidential Information except as expressly permitted in this Agreement.

8.2 Obligation. CyDex and Sage agree that they will disclose the other’s Confidential Information to its (or its respective parent’s) own 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. Neither party shall disclose Confidential Information of the other to any Third Party without the other’s prior written consent, and any such disclosure to a Third Party shall be pursuant to the terms of a non-disclosure agreement no less restrictive than this Section 8. The party which disclosed Confidential Information of the other to any Third Party shall be responsible and liable for any disclosure or use by such Third Party (or its discloses) 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). Unless otherwise specified in this Agreement and subject to terms and conditions in this Agreement, if so requested by the other party a party shall promptly return all relevant records and materials in its possession or control containing or embodying the other party’s Confidential Information (including all copies and extracts of documents); provided, however, that each party may retain 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 records and materials solely to be able to monitor its obligations that survive under this Agreement,

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 appropriate documentation:

(i) at the rime of disclosure is in the public domain;

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

(iii) is independently developed by Receiving Party personnel with no reference or access to the Confidential Information; or

(iv) 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, such information was not obtained by said third party, directly or indirectly, from the Disclosing Party hereunder.

***Text Omitted and Filed Separately with the Securities and Exchange Commission Confidential Treatment Requested Under 17 C.F.R. Sections 200.80(b)(4) and 230.406

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 Securities and Exchange Commission, or in the course of litigation; provided that in all cases the Receiving Party shall give the other party prompt notice of the pending disclosure and make a reasonable effort 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. 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 which is in the possession of a disclosing party.

Sage acknowledges that CyDex’s Confidential Information includes information developed by Pfizer that is confidential to both CyDex and Pfizer. In so far as Confidential Information of Pfizer is disclosed, Pfizer is a third-party beneficiary of this Section 8 of this Agreement and may enforce it or seek remedies pursuant to it in accordance with its terms.

Sage agrees not to disclose to CyDex any Confidential Information of a Third Party which is in the possession of Sage, unless CyDex has given an express prior written consent (which specifies the owner of such Confidential Information) to receive such particular Confidential Information. If CyDex refuses to provide such consent, then any obligation of Sage to provide such information to CyDex under this Agreement shall be deemed waived by CyDex.

8.6 Public Announcements. The parties will mutually agree on a press release to be issued upon execution of this Agreement or reasonably soon thereafter. 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 will submit a draft of the proposed announcement to the other party in sufficient time to enable such other party to consider and comment thereon.

(a) The person 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, and a reasonable explanation of the basis for the Claim and the amount of alleged Losses to the extent of the facts then known by the Indemnified Party. (Notwithstanding the foregoing, 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.) The Indemnifying Party shall assume the defense thereof whether or not such Claim is rightfully brought; provided, however, that if the Indemnifying Party assumes the defense, the Indemnified Party shall have the right to employ counsel separate from counsel employed by the Indemnifying Party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the Indemnified Party shall be at the sole cost and expense of the Indemnified Party unless the Indemnifying Party consents to the retention of such

counsel or unless the named parties to any action or proceeding include both the Indemnifying Party and the Indemnified Party and a representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to the actual or potential differing interests between them. And provided further that, if the Indemnifying Party shall fail to 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 fees and expenses of counsel retained by the Indemnified Party.

(b) 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 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 (i) there is no finding or admission of any violation of law or any violation of the lights of any Person 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 (ii) 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.

(c) Regardless of who controls the defense, the other party hereto shall reasonably cooperate m the defense as may be requested. Without limitation, the Indemnified Party, and its directors, officers, advisers, agents and employees, shall cooperate fully with the Indemnifying Party and its legal representatives in the investigations of any Claim.
