The obligations of confidentiality and nonuse set forth in Section 5.2(a) shall not apply to any specific portion of information that the Receiving Party can demonstrate by competent written proof: (a) is in the public domain or comes into the public domain through no fault of the Receiving Party; (b) is furnished to the Receiving Party by a Third Party rightfully in possession of such information and not subject to a duty of confidentiality with respect thereto; (c) is already known by the Receiving Party at the time of receiving such Confidential Information from the Disclosing Party, as evidenced by the Receiving Party’s prior written records, which shall not include any information relating to the Contributed Assets; or (d) is independently developed by the Receiving Party without access to the Disclosing Party’s Confidential Information.

(c) Authorized Disclosure. Notwithstanding anything to the contrary in this Section 5.2, the Receiving Party may disclose certain Confidential Information of the Disclosing Party to the extent such disclosure:

13

(i) is (A) required by applicable Law, (B) pursuant to a valid order of a court or other governmental body having jurisdiction, (C) made to Governmental Entities or Regulatory Authorities (I) to obtain Patents as expressly permitted in this Agreement or (II) to gain or maintain regulatory approvals or to commercialize Products; provided that, in each case of (A) through (C), such Receiving Party provides such Disclosing Party with reasonable prior written notice of such disclosure and reasonable assistance in obtaining a protective order or confidential treatment preventing or limiting the disclosure and/or requiring that the Confidential Information so disclosed be used only for the purposes for which the applicable Law required, or for which the order was issued;

(ii) is on a “need to know basis” to permitted subcontractors and to employees and agents of such Receiving Party and its permitted subcontractors, each of whom prior to disclosure must be bound by written obligations of confidentiality and non-use no less restrictive than the obligations set forth in this Section 5.2, which for avoidance of doubt, will not permit use of such Confidential Information for any purpose except those permitted by this Agreement; provided, however, that such Receiving Party shall remain responsible for any failure by any Person who receives Confidential Information pursuant to this Section 5.2(c)(ii) to treat such Confidential Information as required under this Section 5.2;

(iii) is made in connection with a public announcement required under the rules of any stock exchange or under securities laws, including in connection with an initial public offering or any subsequent offering of securities of such Receiving Party; or

(iv) is to existing or potential acquirers or merger candidates, existing or potential sublicensees, investment bankers, existing or potential investors, venture capital firms or other financial institutions or investors for purposes of obtaining financing, each of whom prior to disclosure is bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Section 5.2 (but may be of shorter duration).

(d) Return of Confidential Information. Upon termination of the Agreement, or upon written request of the Disclosing Party, the Receiving Party shall promptly return to the Disclosing Party or destroy all documents, notes and other tangible materials representing the Disclosing Party’s Confidential Information and all copies thereof; provided, however, that each Party may retain a single archival copy of the other Party’s Confidential Information for the sole purpose of facilitating compliance with the surviving provisions of this Agreement.

(e) Injunctive Relief. The Parties expressly acknowledge and agree that any breach or threatened breach of Section 5.2 of this Agreement may cause immediate and irreparable harm to the non-breaching Party that may not be adequately compensated by damages. Each Party therefore agrees that in the event of such breach or threatened breach and in addition to any remedies available at law, the non-breaching Party shall have the right to seek equitable and injunctive relief, without bond, in connection with such a breach or threatened breach.

Section 5.3 Regulatory Documentation and Know-How. Promptly following the Effective Date, Licensors will deliver to Licensee, to the extent not previously delivered by Licensors to Licensee, all Existing Know-How and Existing Regulatory Documentation. From time to time thereafter, upon Licensee’s reasonable request, Licensors will deliver to Licensee any Arising Know-How and Arising Regulatory Documentation not previously delivered.

14

Section 5.4 Further Assurances. Following the Effective Date, each of the Parties shall execute and deliver such additional documents, instruments, conveyances and assurances and take such further actions as may be reasonably required to carry out the provisions hereof and give effect to the transactions contemplated by this Agreement and the documents to be delivered hereunder.

ARTICLE VI

Section 6.1 Indemnification by Licensors. Subject to the other terms and conditions of this ARTICLE VI, Licensors shall defend, indemnify and hold harmless Licensee, its Affiliates and their respective stockholders, directors, officers and employees from and against all third party claims, judgments, damages, liabilities, settlements, losses, costs and expenses, including attorneys’ fees and disbursements (collectively, “Losses”), arising from or relating to:

(a) any inaccuracy in or breach of any of the representations or warranties of Licensors contained in this Agreement or any document to be delivered by Licensors hereunder; or

(b) any breach or non-fulfillment of any covenant, agreement or obligation to be performed by Licensors pursuant to this Agreement or any document to be delivered by Licensors hereunder;

except, in each case ((a) and (b)), for those Losses for which Licensee has an obligation to indemnify Licensors, its Affiliates or their respective stockholders, directors, officers and employees pursuant to Section 6.2, as to which Losses each Party shall indemnify the other to the extent of their respective liability.

Section 6.2 Indemnification by Licensee. Subject to the other terms and conditions of this ARTICLE VI, Licensee shall defend, indemnify and hold harmless Licensors, their Affiliates and their respective stockholders, directors, officers and employees from and against all Losses arising from or relating to:

except, in each case ((a), (b) and (c)), for those Losses for which Licensors have an obligation to indemnify Licensee, its Affiliates or their respective stockholders, directors, officers and employees pursuant to Section 6.1, as to which Losses each Party shall indemnify the other to the extent of their respective liability.

Section 6.3 Indemnification Procedures. Whenever any claim shall arise for indemnification hereunder, the Party entitled to indemnification (the “Indemnified Party”) shall promptly provide written notice of such claim to the other Party (the “Indemnifying Party”). Each such notice shall contain a description of the claim and the nature and amount of such Losses (to the extent that the nature and amount of such Losses are known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses. In connection with any indemnifiable Losses arising or relating to any Action by a Third Party, the Indemnifying Party, at its sole cost and expense and upon written notice to the Indemnified Party, may assume the defense of any such Action with counsel reasonably satisfactory to the Indemnified Party. The Indemnified Party shall be entitled to participate in the defense of any such Action, with its counsel and at its own cost and expense. If the Indemnifying Party does not assume the defense of any such Action, the Indemnified Party may, but shall not be obligated to, defend against such Action in such manner as it may deem appropriate, including settling such Action, after giving notice thereof to the Indemnifying Party, on such terms as the Indemnified Party may deem appropriate and no action taken by the Indemnified Party in accordance with such defense and settlement shall relieve the Indemnifying Party of its indemnification obligations under this Agreement with respect to any damages resulting therefrom. The Indemnifying Party shall not settle any Action by a Third Party without the Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 6.4 Limitations. NO PARTY SHALL HAVE ANY LIABILITY TO THE OTHER PARTIES FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, EXCEPT TO THE EXTENT THE SAME ARE AWARDED ARISING OUT OF AN ACTION INVOLVING A THIRD PARTY. EXCEPT FOR AMOUNTS AWARDED TO THIRD PARTIES IN RESPECT OF INDEMNIFICATION, NEITHER PARTY SHALL HAVE ANY LIABILITY TO THE OTHER FOR PUNITIVE OR EXEMPLARY DAMAGES.

ARTICLE VII

Patent Expenses and Prosecution of Contributed Patents; Enforcement

Section 7.1 Direction of Prosecution. As of the Effective Date, Licensee shall be responsible for the cost and strategy of the prosecution and maintenance of the Contributed Patents. Licensors hereby appoint Licensee as its agent to prepare, file, prosecute, maintain and defend in all agency proceedings (e.g. reissues, reexaminations, oppositions and interferences) of all Contributed Patents during the Term. Licensee shall keep Licensors reasonably apprised of developments as they occur for the Contributed Patents, shall copy Licensors on all patent prosecution documents and shall provide Licensors reasonable time to review and comment on any such filings. Licensee shall consider the relevant Licensor’s comments in good faith; provided, however, that Licensee shall maintain final authority in all decisions regarding the prosecution and maintenance of the Contributed Patents.

16

Section 7.2 Abandonment of Rights. If at any time Licensee wishes to cease paying for any costs for a particular Contributed Patent or for patent prosecution thereof in a particular jurisdiction, Licensee must give Licensors at least 90 days prior written notice and Licensee will continue to be obligated to pay for the patent costs which reasonably accrue during said notice period.

Section 7.3 Enforcement. Each Party shall notify the other Parties promptly after becoming aware of any infringement of the Contributed Patents by a third party and of any available evidence thereof. Licensee shall have the first right, but not obligation, under its own control and at its own expense, to prosecute any third party infringement of the Contributed Patents. Licensee must not settle or compromise any such suit in a manner that imposes any material obligations or restrictions on Licensors or grants any rights to the Contributed Patents other than rights that Licensee has the right to grant under this Agreement. In the event Licensee does not bring any such legal action within two (2) months after the date of notice of such infringement (or settle or otherwise secure the abatement of such infringement action) or ceases to diligently pursue such infringement action, Licensors may bring and control any legal action to enforce the Contributed Patents against such infringement, at Licensors’ sole cost and expense. Each Party agrees to cooperate in any action under this Section 7.3 which is controlled by another Party including, without limitation, joining such action as a party plaintiff if necessary or desirable for initiation or continuation of such action; provided that the controlling Party reimburses the cooperating Party(ies) promptly for any reasonable costs and expenses incurred by the cooperating Party(ies) in connection with providing such assistance.

ARTICLE VIII

Miscellaneous

Section 8.1 Term. This Agreement shall become effective as of the Effective Date and shall remain in force until the Parties mutually consent in writing to terminate (“Term”). In the event of termination of this Agreement, all licenses and sublicenses granted under Article II and other rights with respect to the Contributed Assets shall terminate. In the event of termination, Article I, Article III, Article IV, Article V, Article VI, Article VII, and Article VIII shall survive termination.

This Agreement and the documents to be delivered hereunder constitute the sole and entire agreement of the Parties with respect to the subject matter contained herein, and supersede all prior understandings and agreements, both written and oral, with respect to such subject matter. In the event of any inconsistency between the statements in the body of this Agreement and the exhibits and other documents delivered in connection herewith, this Agreement shall control.

Section 8.4 Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction.

18

Section 8.5 Amendment; Waiver. This Agreement may only be amended, modified or supplemented by an agreement in writing signed by each Party. No waiver by any Party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the Party so waiving. No waiver by any Party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. No failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Section 8.6 Assignment. Without limitation of Licensee’s right to grant sublicenses in accordance with Section 2.2, neither Party may assign this Agreement or any of its rights or obligations hereunder without the prior written consent of the other Party, provided that either Party may assign this Agreement or any of the rights, interests or obligations hereunder without the consent of the other Party: (a) to any of its Affiliates; or (b) in connection with the transfer or sale of all or substantially all of such Party’s business or assets to which this Agreement relates to a Third Party, whether by merger, sale of stock, sale of assets or otherwise. Any attempted assignment or delegation in violation of the preceding sentence shall be void and of no effect. Subject to the foregoing, this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns.

Section 8.7 No Third-Party Beneficiaries. This Agreement is for the sole benefit of the Parties and their respective successors and permitted assigns and nothing herein, express or implied, is intended to, or shall, confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 8.8 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive Law of another jurisdiction. The Parties agree to exclude the application to this Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

Section 8.9 Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on the Parties from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other Governmental Entity in accordance with applicable Law.

19

Section 8.10 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Licensors are, and shall otherwise be deemed to be, for purposes of § 365(n) of the US Bankruptcy Code, licenses of rights to “intellectual property” as defined under § 101 of the US Bankruptcy Code or similar provision in the bankruptcy laws of another jurisdiction (the “Code”). The Parties agree that Licensee, as licensee of intellectual property under this Agreement, shall retain and may fully exercise all of its rights and elections under the Code. The Parties further agree that in the event of a rejection of this Agreement by a Licensor in any bankruptcy proceeding by or against such Licensor under the Code: (a) Licensee shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property that are necessary for Licensee to practice its license to such intellectual property, which, if not already in Licensee’s possession, shall be promptly delivered to it upon its written request therefor; and (b) no Licensor shall interfere with Licensee’s rights to such intellectual property, and each Licensor shall assist and not interfere with Licensee in obtaining such intellectual property and such embodiments of such intellectual property from another entity. The term “embodiments” of intellectual property means all tangible embodiments of the intellectual property licensed hereunder to the extent of the license scope. All rights, powers and remedies provided in this Section 8.10 are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Code) in the event of the commencement of a case under the Code.

Section 8.11 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall be deemed to be one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail PDF or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.
