Subject to the terms and conditions of this Agreement, Penn hereby grants to Licensee an exclusive, worldwide, royalty-bearing right and license (with the right to sublicense as provided in, and subject to, the provisions of Section 2.4) under Penn Patent Rights to make, have made, use, sell, offer for sale and import Product in the Field of Use during the Term (the “License”).

Notwithstanding the License, Penn retains the right under Penn Patent Rights in the Field of Use to conduct educational and non-commercial research activities, and to authorize non-commercial Third Parties to conduct educational and non-commercial research activities. Penn may request permission from Licensee to conduct clinical activities under the Penn Patent Rights in the Field of Use, provided, however, that Penn may not conduct any such clinical activities in the Field of Use without Licensee’s written consent, which may be withheld in Licensee’s sole discretion. For clarity, Penn retains the right to use, and to authorize others to use, the Penn Patent Rights outside the Field of Use for any purpose.

2.3 U.S. Government Rights. The License is expressly subject to all applicable provisions of any license to the United States Government executed by Penn and is subject to any overriding obligations to the United States Federal Government under 35 U.S.C. §§200-212, applicable governmental implementing regulations, and the U.S. Government sponsored research agreement or other guidelines, including that products that result from intellectual property funded by the United States Federal Government that are sold in the United States be substantially manufactured in the United States. In the event that Licensee or its Sublicensee believes in good faith that substantial manufacture of such product is not commercially feasible in the United States, and Licensee makes a request to Penn in writing to assist in obtaining a waiver of such requirement from the United States Government, then Penn shall, at the expense of Licensee, use reasonable efforts to assist Licensee or Sublicensee in obtaining such waiver.

The term Sublicense shall include any grant of rights under the License by a Sublicensee to any downstream Third Party, such downstream Third Party shall also be considered a Sublicensee for purposes of this Agreement.

2.4.2 All Sublicenses will be (a) issued in writing, (b) to the extent applicable, include all of the rights of Penn and require the performance of obligations due to Penn (and, if applicable, the U.S. Government under 35 U.S.C. §§200-212) contained in this Agreement and (c) shall include no less than the following terms and conditions:

(a) Reasonable record keeping, audit and reporting obligations sufficient to enable Licensee and Penn to reasonably verify the payments due to Licensee and Penn under such Sublicense and to reasonably monitor such Sublicensee’s progress in developing and/or commercializing Product, provided that such obligations shall be no less stringent that those provided in this Agreement for Licensee.

CONFIDENTIAL

EXECUTION COPY

(b) Infringement and enforcement provisions that do not conflict with the restrictions and procedural requirements imposed on Licensee and do not provide greater rights to Sublicensee than as provided in Section 5.4.

2.4.3 Within thirty (30) days after of the execution of a Sublicense Document, Licensee shall provide a complete and accurate copy of such Sublicense Document to Penn, in the English Language. Penn’s receipt of a Sublicense Document, however, will constitute neither an approval nor disapproval of the Sublicense Document nor a waiver of any right of Penn or obligation of Licensee under this Agreement.

2.4.4 Licensee shall provide an annual Sublicense Development Report on or before December 1 of each year during the Term (“SDR Report”) a form of which is attached hereto as Appendix III.

2.5 No Implied License. Each Party acknowledges that the rights and licenses granted in this Agreement are limited to the scope expressly granted. Accordingly, except for the rights expressly granted under this Agreement, no right, title, or interest of any nature whatsoever is granted whether by implication, estoppel, reliance, or otherwise, by either Party to the other Party. All rights with respect to any know-how, patent or other intellectual property right rights that are not specifically granted herein are reserved to the owner thereof.

4.7 Royalty and Penn Sublicense Income Reports. Within [***] ([***]) days after the end of each calendar quarter (i.e., March 31, June 30, September 30 and December 31), Licensee shall deliver to Penn a report (“Financial Report”) setting out all details necessary to calculate the

4.7.8 Date of First Commercial Sale in the United States (this need only be reported in the first royalty report following such First Commercial Sale in the United States).

4.8 Late Payments. In addition to any other remedies available to Penn, including the right to terminate this Agreement, any failure by Licensee to make a payment within [***] ([***]) days after the date when due shall obligate Licensee to pay computed interest, the interest period commencing on the due date and ending on the actual payment date, to Penn at a rate per annum equal to [***] percent ([***]%) per month, or the highest rate allowed by Law, whichever is lower.

4.9 Accounting. Each Party shall calculate all amounts, and perform other accounting procedures required, under this Agreement and applicable to it in accordance with GAAP.

4.10 Books and Records. Licensee will keep accurate books and records of all Products developed, manufactured, used or sold and all Sublicenses, collaboration agreements and joint venture agreements entered into by Licensee that involved Penn Patent Rights. Licensee will preserve these books and records for at least [***] ([***]) years from the date of the Financial Report to which they pertain. Upon reasonable notice, key personnel, books and records will be made reasonably available and will be open to examination by representatives or agents of Penn during regular office hours to determine their accuracy and assess Licensee’s compliance with the terms of this Agreement, provided that Licensee shall not have an obligation to provide access more than [***] in any given [***] ([***]) month period.

4.11 Audits. In addition to the right of Penn to examine the books and records and interview key personnel as provided in Section 4.10 above, Penn, at its own cost, through an independent auditor reasonably acceptable to Licensee (and who has executed an appropriate confidentiality agreement reasonably acceptable to Licensee that requires the auditor to keep any information learned by it confidential except as needed to report its audit conclusions to Penn), may inspect and audit the relevant records of Licensee pertaining to the calculation of any Milestones, Royalties and Penn Sublicense Income due to Penn under this Agreement. Licensee shall provide such auditors with access to the records during reasonable business hours. Such access need not be given to any such set of records more often than [***] each year or more than [***] ([***]) years after the date of any report to be audited. Penn shall provide Licensee with written notice

CONFIDENTIAL

EXECUTION COPY

of its election to inspect and audit the records related to the Royalty due hereunder not less than [***] ([***]) days prior to the proposed date of review of Licensee’s records by Penn’s auditors. Should the auditor find any underpayment of Milestones, Royalties or Penn Sublicense Income by Licensee, Licensee shall (a) promptly pay Penn the amount of such underpayment; (b) shall reimburse Penn for the cost of the audit, if such underpayment equals or exceeds the higher of (i) [***] United States dollars ($[***]) or (ii) [***] percent ([***]%) of Royalties or Penn Sublicense Income paid during the time period audited; and (c) provide such auditors with an audit right exercisable within [***] ([***]) months after Licensor receives the audit report. If the auditor finds overpayment by Licensee, then Licensee shall have the right to deduct the overpayment from any future royalties due to Penn by Licensee or, if no such future royalties are payable, then Penn shall refund the overpayment to Licensee within [***] ([***]) days after Licensor receives the audit report. Licensee may designate competitively sensitive information which such auditor may see and review but which it may not disclose to Licensor; provided, however, that such designation shall not restrict the auditor’s investigation or conclusions.

4.12 Taxes.

4.12.1 All payments made by Licensee to Penn under the Agreement shall be made free and clear of and without any deduction for or on account of any Taxes on or with respect to such payments.

4.12.2 Penn is a tax exempt entity in the U.S. and qualifies under treaties for tax exempt treatment in many jurisdictions. All payments by Licensee to Penn are made without deduction for or net of Taxes. To the extent that Taxes are required to be withheld in any jurisdiction on account of any payments hereunder, Licensee shall pay such Taxes on behalf of Penn to the appropriate governmental authority, without reducing amounts payable to Penn hereunder. The Parties will cooperate with one another with respect to all documentation required by any taxing authority or reasonably requested by Licensee or Penn to secure a reduction in the rate of applicable withholding Taxes.

ARTICLE 5

INTELLECTUAL PROPERTY

5.1 Patent Filing Prosecution and Maintenance.

5.1.1 Penn Patent Rights will be held in the name of Penn and obtained with counsel selected by Penn and reasonably acceptable to Licensee (“Patent Counsel”). Penn shall control all actions and decisions with respect to the filing, prosecution and maintenance of Penn Patent Rights and will consider any reasonable comments, suggestions, drafts or directions by Licensee with respect to same. Penn will instruct Patent Counsel to copy Licensee on all correspondence related to Penn Patent Rights (including copies of correspondence to and from patent offices, correspondence related to Patent Rights, reporting letters to Penn, each patent application, office action, response to office action, request for terminal disclaimer, and request for reissue or reexamination of any patent or patent application) and to interact with Licensee with respect to the preparation, filing, prosecution and maintenance of Penn Patent Rights. The Parties have the right to take action to preserve rights or minimize cost. Penn has the right to act where Licensee has not commented. Penn will use reasonable efforts to not allow any Penn Patent Rights for which Licensee is licensed and is underwriting the costs to lapse or become abandoned without Licensee’s written authorization under this Agreement. Penn shall have no [***] as set forth in this Agreement. Within

CONFIDENTIAL

EXECUTION COPY

[***] ([***]) days of the Effective Date, Penn will cause Patent Counsel to [***]. Licensee will bear and shall reimburse Penn for all Patent Costs associated with such [***]. Licensee may assist in preparation of [***].

5.1.2 Licensee has the right to request a country filing via a written request to Penn within a reasonable time but not less than [***] ([***]) days prior to the deadline set by the patent office in the territory in which filing is to take place (“Prosecution Request”). The absence of a given Prosecution Request by such deadline will be considered an election not to secure the Patent Rights associated with the specific phase of patent prosecution in such territory, and such patent application(s) and patent(s) (“Carve-Out Patent Rights”) will not be part of Penn Patent Rights and therefore not subject to this Agreement, including the License, and Licensee will have no further rights or license to them.

5.2 Patent Costs.

5.2.1 Within [***] ([***]) days of the date that Licensee achieves the Essential Milestone, Penn will invoice Licensee for all out-of pocket costs for the filing, prosecution and maintenance of Penn Patent Rights, including all accrued attorney fees, expenses, official and filing fees (“Patent Costs”), incurred prior to the Effective Date and not already paid or payable pursuant to the Option Agreement or reimbursed to Penn by any party for past filing, prosecution and maintenance (“Historic Patent Costs”). Such Historical Patent Costs total [***] ($[***]).

5.2.2 Licensee will bear all Patent Costs in the Field of Use incurred during the Term (“Ongoing Patent Costs”). Penn will invoice Licensee for all Ongoing Patent Costs promptly after receipt and docketing in Penn’s invoicing system of such invoices for such Ongoing Patent Costs from Patent Counsel. If Penn enters into a license agreement with a Third Party for any of the Penn Patent Rights outside the Field of Use, then Penn will [***]. For the sake of clarity, Licensee will not [***]; whether [***].

5.2.3 At any time, at Penn’s request, Licensee shall [***] for regional validations (including, European validation and associated costs), new original patent applications (including significant new matter continuations-in-part) reexaminations and national phase entry filings requested by Licensee [***] (“[***]”). If the Patent Counsel’s [***], the portion of such [***] shall be [***].

5.2.4 Notwithstanding [***], Licensee shall bear all Patent Costs incurred during the Term and shall pay such amounts within [***] ([***]) days of receipt of invoice for such patent actions. For clarity, the term “Patent Costs” means and includes Historic Patent Costs and Ongoing Patent Costs.

5.3 Termination of Rights in, and Obligations with respect to, Certain Penn Patent Rights. Licensee may terminate its rights in, and obligations with respect to any or all of Penn Patent Rights by providing written notice to Penn of Licensee’s decision to terminate such Penn Patent

CONFIDENTIAL

EXECUTION COPY

Rights (“Patent Termination Notice”). Termination of Licensee’s rights in and obligation with respect to such Patent Right will be effective [***] ([***]) months after receipt of such Patent Termination Notice by Penn. Penn will immediately curtail Patent Costs chargeable to Licensee under this Agreement after the receipt of the Patent Termination Notice is received. Penn may continue prosecution and maintenance of such Patent Rights at its sole discretion and expense, and such Patent Rights will then be Carve-Out Patent Rights and therefore not subject to this Agreement, including the License, and Licensee will have no further rights or license to them.

5.4 Infringement.

5.4.1 If either Party believes that an infringement by a Third Party with respect to any Penn Patent Right is occurring or may potentially occur, the knowledgeable Party will provide the other Party with (a) written notice of such infringement or potential infringement and (b) evidence of such infringement or potential infringement (the “Infringement Notice”). During the period in which, and in the jurisdiction where, Licensee has exclusive rights under this Agreement, neither Penn or Licensee will notify such a Third Party (including the infringer) of infringement or put such Third Party on notice of the existence of Penn Patent Rights without first obtaining the written consent of the other Party (such consent not to be unreasonably withheld, delayed or conditioned). Both Penn and Licensee will use their diligent efforts to cooperate with each other to terminate such infringement without litigation.

5.4.2 If infringing activity of potential commercial significance has not been abated within [***] ([***]) days following the date the Infringement Notice for such activity was provided, then during the period in which, and in the jurisdiction where, Licensee has exclusive rights under this Agreement, Licensee may institute suit for patent infringement against the infringer after providing Penn (a) a written estimate of the expenses that would be reasonably incurred in connection with such action, including an estimate from an outside law firm, acceptable to Penn, regarding the legal costs associated with such suit and (b) financial records reasonably sufficient to reasonably demonstrate that Licensee has the financial wherewithal to pay such expenses as they fall due through the conclusion of such suit by means of judgment or other final non-appealable decision. Penn may voluntarily join such suit at Licensee’s reasonable expense, but may not thereafter commence suit against the infringer for the acts of infringement that are the subject of Licensee’s suit or any judgment rendered in such suit. Licensee may not join Penn in a suit initiated by Licensee without Penn’s prior written consent, such consent not to be unreasonably withheld, delayed or conditioned. If in a suit initiated by Licensee, Penn is involuntarily joined other than by Licensee, then Licensee will pay any documented costs incurred by Penn arising out of such suit, including any documented legal fees of counsel that Penn selects and retains to represent it in the suit. Licensee shall be free to enter into a settlement, consent judgment or other voluntary disposition, provided that any settlement, consent judgment or other voluntary disposition that (i) limits the scope, validity or enforcement of Penn Patents or (ii) admits fault or wrongdoing on the part of Licensee or Penn must be approved in advance by Penn in

CONFIDENTIAL

EXECUTION COPY

5.4.3 writing, such approval not to be unreasonably withheld, delayed or conditioned. Licensee’s request for such approval shall include complete copies of final settlement documents, a detailed summary of such settlement, and any other information material to such settlement. Penn shall provide Licensee notice of its approval or denial within [***] ([***]) days of any request for such approval by Licensee, provided that (x) in the event Penn wishes to deny such approval, such notice shall include a detailed written description of Penn’s reasonable objections to the proposed settlement, consent judgment, or other voluntary disposition and (y) Penn shall be deemed to have approved of such proposed settlement, consent judgment, or other voluntary disposition in the event it fails to provide such notice within such [***] ([***]) day period in accordance herewith.

5.4.4 If, within [***] ([***]) days following the date the Infringement Notice was provided, infringing activity of potential commercial significance has not been abated and if Licensee has not brought suit against the infringer, then Penn may institute suit for patent infringement against the infringer. If Penn institutes such suit, then Licensee may not join such suit without the prior written consent of Penn and may not thereafter commence suit against the infringer for the acts of infringement that are the subject of Penn’s suit or any judgment rendered in such suit.

5.4.5 Notwithstanding Sections 5.4.2 and 5.4.3, in the event that any Penn Patent Rights are infringed by a Third Party if any of the infringed Penn Patent Rights are also licensed by Penn to a Third Party, prior to any enforcement action being taken by either Party regarding such infringement, the Parties shall discuss, and will mutually agree, in writing, as to how to handle such infringement by such Third Party.

5.4.6 Any recovery or settlement received in connection with any suit will first be shared by Penn and Licensee equally to cover any litigation costs each incurred and next shall be paid to Penn or Licensee to cover any litigation costs it incurred in excess of the litigation costs of the other. Any remaining recoveries shall be allocated as follows:

For any portion of the recovery or settlement related to the infringement of the Penn Patent Rights, other than for amounts attributable and paid as enhanced damages for willful infringement:

(a) for any suit that is initiated by Licensee and in which Penn was not a party in the litigation, Penn shall receive [***] percent ([***]%) of the recovery, and the Licensee shall receive the remainder; and

(b) for any suit that is initiated by the Licensee or Penn and that the other Party joins voluntarily (but only to the extent such voluntary joining is allowed under this Agreement or expressly by the other Party in a separate agreement) or involuntarily, the non-initiating party’s percentage of such recovery shall be [***] percent ([***]%) .

For any portion of the recovery or settlement related to the infringement of the Penn Patent Rights paid as enhanced damages for willful infringement:

(c) for any suit that is initiated by Licensee or Penn and the other Party voluntarily but only to the extent such voluntary joining is allowed under this Agreement or expressly by the other Party in a separate agreement) or involuntarily, the non-initiating party’s percentage of such recovery shall be [***] percent ([***]%) and Licensee shall receive the remainder; and

CONFIDENTIAL

EXECUTION COPY

(d) for any suit that is initiated by Licensee and in which Penn was not a party in the litigation, Penn shall receive [***] percent ([***]%) and the Licensee shall receive the remainder.

For any portion of the recovery or settlement received in connection with any suit that is initiated by Penn and in which Licensee was not a party in the litigation, any recovery in excess of litigation costs will [***].

5.4.7 Each Party will reasonably cooperate and assist with the other in litigation proceedings instituted hereunder but at the expense of the Party who initiated the suit (unless such suit is being jointly prosecuted by the Parties). For clarity, such requirement does not require a Party to join a suit unless otherwise specifically required under this Agreement. If Penn is [***] related to the Penn Patent Rights or Products licensed to Licensee hereunder, [***] with respect to same.

5.5 Patent Marking. Licensee shall place in a conspicuous location on any Product (or its packaging where appropriate and practicable) made or sold under this Agreement a patent notice in accordance with the Laws concerning the marking of patented articles where such Product is made or sold, as applicable.

5.6 Confidentiality.

5.6.1 Each Party agrees that, for the Term and for [***] ([***]) years thereafter, such Party shall (a) use the same degree of care to maintain the secrecy of the Confidential Information of the other Party that it uses to maintain the secrecy of its Confidential Information of like kind, (b) use the Confidential Information only to accomplish the purpose of this Agreement or for audit or management purposes and (c) ensure that any employees, customers, and distributors are bound to it by similar obligations of confidence and to make sure such disclosure only as required to accomplish the purposes of this Agreement. Licensee may disclose for the purposes set forth above Penn’s Confidential Information on a need to know basis to Licensee’s: Affiliates; potential or actual collaborators, partners, and Sublicensees (including potential co-marketing and co-promotion contractors); potential or actual investment bankers, acquirers, lenders or investors; employees; consultants; and agents, provided that (i) prior to disclosure each such recipient, is bound by written obligations of confidentiality and non-use at least as restrictive as those as set forth in this Agreement (but, in any event, not less than reasonable measures to protect the secrecy of, and avoid the unauthorized disclosure or use of, Penn Confidential Information). and (ii) such recipient may not further disclose such Confidential Information to any third party. Licensee shall be primarily liable to Penn for any breach of this Agreement or such obligations of non-use and non-disclosure by Licensee’s Affiliates, Sublicensees or any such other recipient(s) of Penn’s Confidential Information.

5.6.2 A Party may disclose the Confidential Information of the other Party to the extent required by Law or court order; provided, however, that the recipient promptly provides to the disclosing Party prior written notice of such disclosure and provides reasonable assistance in obtaining an order or other remedy protecting the Confidential Information from public disclosure.

5.6.3 If Licensee is required by applicable law, rule or regulation to make a securities filing relating to the execution of this Agreement with the appropriate governmental authorities

CONFIDENTIAL

EXECUTION COPY

(including the U.S. Securities and Exchange Commission, and any securities exchange on which securities of Licensee are listed), then Licensee will prepare a draft of such securities filing for review and comment by Penn. If such securities filing includes the disclosure of this Agreement and its terms, Licensee will include a confidential treatment request and a proposed redacted version reasonably in advance of the deadline for such securities filing, and Penn agrees to promptly (and in any event, no less than [***] ([***]) days (or such shorter time to meet any filing deadline where it was not practical to provide the other Party with [***] ([***])-days’ notice after receipt of such confidential treatment request and proposed redactions) give its input in a reasonable manner in order to allow Licensee to file its request within the timelines proscribed by the regulations of applicable governmental authority or securities exchanged as represented by the redacted version reviewed by Penn.

INDEMNIFICATION; INSURANCE AND LIMITATION OF LIABILITY

7.1 Indemnification by Licensee.

7.1.1 Licensee shall defend, indemnify and hold Penn and its respective trustees, officers, faculty, students, employees, contractors and agents (the “Penn Indemnitees”) harmless from and against any and all liability, damage, loss, cost or expense (including reasonable attorneys’ fees), including, without limitation, bodily injury, risk of bodily injury, death and property damage to the extent arising out of Third Party claims or suits related to (a) this Agreement or any Sublicense, including (i) the development, testing, use, manufacture, promotion, sale or other disposition of any Product (including any product liability claim), (ii) any enforcement action or suit brought by Licensee against a Third Party for infringement of Penn Patent Rights, (iii) any claim by a Third Party that the practice of Penn Patent Rights or the design, composition, manufacture, use, sale or other disposition of any Product infringes or violates any patent, copyright, trade secret, trademark or other intellectual property right of such Third Party, (iv) any breach of this Agreement or Laws by Licensee, its Affiliates or Sublicensees and (b) Licensee’s negligence, omissions or willful misconduct, provided that Licensee’s obligations pursuant to this Section 7.1 shall not apply to the extent such claims or suits result from the negligence, gross negligence or willful misconduct of any of Penn Indemnitees as determined by a court of law.

ARTICLE 8
TERM AND TERMINATION

8.1 Term. The term of this Agreement (the “Term”) shall commence on the Effective Date and, unless terminated sooner, shall continue in full force and effect until the expiration or abandonment of the last Valid Claim of the last Penn Patent Right. Notwithstanding the foregoing, this Agreement shall automatically terminate in its entirety upon the failure of Licensee to achieve the Essential Milestone as set forth in Exhibit B. For the avoidance of doubt, the expiration of the Term due to Licensee’s failure to achieve the Essential Milestone will not require written or verbal notice that such milestone has not been achieved as required or that the Agreement has expired due to such failure.

8.2 Termination of the Agreement for Convenience. At any time during the Term, Licensee may, at its convenience, terminate this Agreement upon providing at least sixty (60) days prior written notice to Penn of such intention to terminate, provided that Licensee ceases using the License or making, using, or selling Products.

8.3 Termination For Cause.

8.3.1 If Licensee fails to fulfill its obligations under Section 3.2 (i.e. use Commercially Reasonable Efforts to develop and commercialize a Product), Penn may provide written notice to Licensee of such failure. If Licensee fails to address such failure to the reasonable satisfaction of Penn within three (3) months of receiving such written notice, Penn may terminate this Agreement upon written notice to Licensee.

8.3.2 If, after [***] as set forth in the Essential Milestone, Licensee fails at any time during the Term to maintain such [***], and Licensee does not (within [***] ([***]) months of the termination of the [***]) obtain [***] and provide Penn with written documentation thereof, then Penn may terminate this Agreement effective upon thirty (30) days written notice to Licensee.

8.3.3 In the event Licensee fails to achieve any Diligence Event by the corresponding Achievement Date (subject to any extensions under Section 3.3), Penn has the right and option to terminate this Agreement, upon written notice, with immediate effect.

8.3.4 If Licensee materially breaches any of its material obligations under this Agreement, Penn may give to Licensee a written notice specifying the nature of the default, requiring it to cure such breach, and stating its intention to terminate this Agreement. If such breach is not cured within thirty (30) days of such notice, such termination shall become effective upon a notice of termination by Penn thereafter. For clarity, a breach of a material obligation includes:

(d) grant of a sublicense under the Penn Patent Rights that is not in accordance with the terms of this Agreement;

(e) failure to terminate a Sublicense where Sublicensee is in breach of the obligations on it pursuant to (i) Sections 2.4.2(a), 2.4.2(c), 2.4.2(f) and 2.4.2(g) and fails to cure such breach within thirty (30) days of being notified of such breach and (ii) Section 2.4.2(d).

8.3.5 In addition to all other remedies available to it, Penn may terminate this Agreement, upon written notice, with immediate effect, upon a breach of Section 6.3, Covenants of Licensee.

8.3.6 Penn may terminate this Agreement, upon written notice, with immediate effect if, at any time, Licensee is unable to pay its debts, including any debts related to exclusive Sublicensees, when they come due, or files in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of Licensee or of its assets, or if Licensee proposes a written agreement of composition or extension of its debts, or if Licensee is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not dismissed within ninety (90) days after the filing thereof, or if Licensee proposes or is a party to any dissolution or liquidation, or if Licensee makes an assignment for the benefit of its creditors of all or substantially all its assets (in each case, “Bankruptcy Action”).

8.4 Effects of Termination.

8.4.1 Notwithstanding the termination of this Agreement, the following provisions shall survive: Sections 4.8-4.12, inclusive, 5.6 and 8.4 and Articles 6, 7 and 9.

8.4.2 Termination of this Agreement shall not relieve the Parties of any obligation or liability that, at the time of termination, has already accrued hereunder, or which is attributable to a period prior to the effective date of such termination.
