4.3.1.1

The exclusion of Supervax Program Products, Theravax Program Product, Cytovax Program Products and Heplisav Program Products from the foregoing license means (without limitation) that such license does not extend to the making and selling of Hepatitis B surface antigen (or any other ingredient covered by or made using the RBG IP) for inclusion (or under contractual terms that would permit their inclusion) in any Supervax Program Product(s), Theravax Program Product(s), Cytovax Program Product(s) and/or Heplisav Program Product(s). Accordingly, RBNV and their Affiliates shall only supply Hepatitis B surface antigen, made using RBG IP, and such other ingredients to third parties under circumstances in which such third parties (and any entities to which they may transfer such antigen and other ingredients) are legally forbidden and precluded from making Supervax Program Products, Theravax Program Products, Cytovax Program Product and Heplisav Program Products using the supplied quantities of such antigen and other ingredients. Notwithstanding the foregoing, RBNV and its Affiliates shall not be required to amend their existing agreements to comply with the restrictions specified in this Section 4.3.1, but shall exert its reasonable diligent efforts, which do not adversely financially impact RBNV, to include such terms upon amendment thereof and shall include them on any voluntary extension to the relationship (i.e. one that is not required without RBNV’s or its Affiliate’s consent under the contract that exists as of the Closing Date).

4.3.2.1

The foregoing license explicitly does not extend to the making and selling of Hepatitis B surface antigen (or any other ingredient covered by or made using the RBG IP) for inclusion (or under contractual terms that would permit their inclusion) in any Supervax Program Product(s), Theravax Program Product(s), Cytovax Program Product(s) and/or Heplisav Program Products. Accordingly, RBNV and their Affiliates shall only supply Hepatitis B surface antigen, made using RBG IP, and such other ingredients to third parties under circumstances in which such third parties (and any entities to which they may transfer such antigen and other ingredients) are legally forbidden and precluded from making Supervax Program Products, Theravax Program Products, Cytovax Program Product and Heplisav Program Products using the supplied quantities of such

Notwithstanding the foregoing, RBNV and its Affiliates shall not be required to amend their existing agreements to comply with the restrictions specified in this Section 4.3.2, but shall exert its reasonable diligent efforts, which do not adversely financially impact RBNV, to include such terms upon amendment thereof and shall include them on any voluntary extension to the relationship (i.e. one that is not required without RBNV’s or its Affiliate’s consent under the contract that exists as of the Closing Date).

	4.3.3		For the avoidance of doubt, the licenses of Section 4.3.1 and 4.3.2 do not in any way diminish the scope of RBG’s rights to the Supervax Program Products, Theravax Program Products and Cytovax Program Products.

	4.3.4		Sublicense Rights and Restrictions. The licenses of both Sections 4.3.1 and 4.3.2 are subject to restrictions on RBG’s ability to license and sublicense pursuant to pre-existing third-party agreements (i.e. agreements with entities other than Affiliates). Other than such third party licensing restrictions:

	(1)		RBNV’s non-exclusive license rights provided in subsection 4.3.1 above are sublicensable in conjunction with the grant of a license or sublicense under *[ ]**

	(2)		RBNV’s exclusive license rights provided in subsection 4.3.2 above, are sublicensable *[ ]** without any requirement that RBNV license other intellectual property in conjunction with the grant of the sublicense.

	(3)		To avoid any doubt, any sublicensees under the license of subsection 4.3.1 and any sublicensees under the license of Section 4.3.2 shall be subject to the same restrictions as stated in Sections 4.3.1.1 and 4.3.2.1, respectively, as if such sublicensees were RBNV or an RBNV Affiliate.

4.3.5

RBG Obligation to Secure Third Party Licensor Consent. At RBNV’s written request, RBG shall promptly notify each third party licensor of RBG IP, of RBG’s obligation under Section 4.3 to sublicense rights in such RBG IP to RBNV, and if consent or amendment under the appropriate license agreement is required, then RBG shall [ * ] to obtain written consent from each such third party licensor. Promptly upon securing each required consent from a third party licensor, if the terms of the consent are acceptable to RBNV, then the Parties shall execute a formal sublicense agreement with RBNV providing for (1) the sublicense of RBG IP rights to RBNV, and (2) the assumption of obligations by RBNV as provided for in such third party license agreements. If any such sublicense requires the payment of monies to the third party licensor (including any payment in the form of an amendment that results in a payment of less money to RBG under the contract than without such amendment), RBNV shall be informed in writing of such potential financial obligation, and RBNV shall be responsible for the payment of all such fees to said third party licensor. RBNV shall be entitled to terminate such sublicense in accordance with its terms, but shall not in this manner be able to avoid responsible for any non-cancelable sublicensing-related fees.

In this case, optionally, at RBNV’s sole discretion, RBNV may do so in its own name; provided that RBG and Dynavax will receive a non-exclusive license to such RBG Patents, consistent with the licenses granted herein and with any pre-existing third party agreements (i.e. if 3rd party obligations exist that apply to the practice of the inventions claimed in the RBG Patents taken over by RBNV, then RBNV must comply with such 3rd party license obligations respecting such practice). If RBG and Dynavax choose, as part of a strategic move, to abandon a particular RBG Patent, which does not claim specifically *[ ] and which would reasonably benefit the RBG Patent portfolio, then the Parties will diligently [ * ]**

	4.4		Defense of Patent Litigation. If either Party after the Closing is warned or sued by a third party alleging or charging infringement of any Patents claiming the licensed Know How or the use thereof by either Party or its Affiliates, then the Party that was warned or sued shall notify promptly the other Party. Except only if, as and to the extent otherwise provided in Article 8, each Party shall be responsible, at its expense, for settling and/or defending such warning, allegation or charge (including associated litigation) to the extent relating to such Party’s or its Affiliates’ use of the licensed Know-How. *[ ]** Upon a Party’s reasonable request, the other Party agrees to reasonably assist in any such defense on mutually agreed reasonable terms, provided that the requesting Party agrees to reimburse the other Party for the reasonable out of pocket expenses incurred by the other Party for the provision of such assistance. Dynavax and RBG are considered a single “Party” for purposes of this Section 4.4.

	4.5		Patent Enforcement.

	4.5.1		Notification. In the event that a Party obtains actual knowledge that a third party’s activities likely infringe one or more of the RBG Patents within the scope of the exclusive license granted in Section 4.3.2, it shall promptly notify the other Party of any such likely infringement.

	4.5.2		Control of Suit:

4.5.2.1

As to the infringement of exclusively licensed RBG Patents pursuant to Section 4.3.2, RBG shall have the first right to effect termination of such infringement, including bringing suit or other proceedings against the infringer in its own name and the other Parties hereto shall be kept informed at all times of all such proceedings taken by RBG. If RBNV, or

12.

CONFIDENTIAL

			another Party licensee, requests, such Party may join with RBG as a Party to the lawsuit or other proceeding in a monitoring capacity only at its own expense. However, even if RBNV chooses to join the suit in such a monitoring capacity, RBG shall retain sole control of the prosecution of such suit or proceedings, as the case may be.

	4.5.2.2		If (a) RBG elects not to file legal proceedings against a third party within *[ ]** such possible infringing activities, and has not engaged in, or has terminated, reasonably diligent business discussions to terminate such infringement, and (b) the infringement involves the commercialization of a product that competes directly with any then-marketed product of RBNV or any of its Affiliates, and if the alleged infringement is likely to have a more than insignificant impact on RBNV’s business in the country(ies) where sales of allegedly infringing product is occurring, then RBNV shall have the right to effect termination of such infringement, including bringing suit or other proceedings against the infringer in its own name. The other Parties hereto shall be kept informed at all times of all such proceedings taken by RBNV. RBNV shall not be authorized to make any admission, consent, or other representation during the proceeding, which would admit the invalidity or unenforceability of an RBG Patent, without the advice and consent, in writing, from RBG, which RBG is entitled to withhold in its reasonable discretion. If RBG (or an RBG Affiliate) requests, such entity may join with RBNV as a party to the lawsuit or other proceeding at its own expense. In this case, RBNV shall retain control of the prosecution of such suit or proceedings, as the case may be, except that RBG shall have the sole right to control the prosecution of such suit or proceedings as regards all matters affecting validity and/or enforceability of the RBG Patent(s).

	4.5.3		Costs and Monetary Recovery: Each Party shall bear all its costs incurred in connection with such lawsuit or other proceeding. Any monetary recovery shall first be paid to the Parties (and their Affiliates) to reimburse their legal and other costs associated with the legal proceeding. *[ ] remaining recovery shall be paid to or retained by RBNV, [ * ]** remaining recovery shall be paid to or retained by RBG.

	4.5.4		Disclaimer. Nothing in this Agreement shall be construed as obligating any Party the right, to proceed against a third party infringer.

	4.5.5		Area of No RBNV Enforcement Rights. RBNV and its Affiliates shall not have any right to enforce the RBG Patents outside the scope of the exclusive license in Section 4.3.2 during the time period while it remains exclusive. Without limitation, this means that RBNV and its Affiliates have no right to enforce the RBG Patents within the scope of the non-exclusive license of Section 4.3.1, to the extent broader than the license of Section 4.3.2 (i.e. outside of any overlap between Section 4.3.1 and Section 4.3.2).

For the avoidance of any doubt, RBG and Dynavax shall not be liable for any financial obligations to third parties, including for example upstream royalties or other payments, arising out of RBNV’s or its Affiliates’ exercise of rights to third-party RBG IP sublicensed hereunder.

	8.1.3		Cooperation. The Parties shall cooperate in the mechanics of making payment to any upstream licensors.

8.3

Indemnification Procedure. If a Party (the “Indemnitee”) intends to claim indemnification under Section 8, Indemnitee shall promptly notify the other Party (the “Indemnitor”) of any claim, demand, action, or other proceeding for which the Indemnitee intends to claim such indemnification. The Indemnitor shall have the right to participate in, and to the extent the Indemnitor so desires jointly with any other Indemnitor similarly noticed, to assume the defense thereof with counsel selected by the Indemnitor; provided, however, that the Indemnitee shall have the right to retain its own counsel at Indemnitee’s own expense. The indemnity obligations under this Article 8 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the prior express written consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed. The failure to deliver notice to the Indemnitor within a reasonable time after notice of any such claim or demand, or the commencement of any such action or other proceeding, only to the extent actually prejudicial to its ability to defend such claim, demand, action or other proceeding, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 8 with respect thereto, but the omission so to deliver notice to the Indemnitor shall not relieve it of any liability that it may have to the

17.

CONFIDENTIAL

Indemnitee otherwise than under this Article 8. The Indemnitor may not settle or otherwise consent to an adverse judgment in any such claim, demand, action or other proceeding, that diminishes the rights or interests of the Indemnitee without the prior express written consent of the Indemnitee, which consent shall not be unreasonably withheld or delayed. The Indemnitee, its Affiliates, and all of their employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this Section 8.

If the Parties cannot in good faith agree as to the application of Section 8.2 to any particular Claim, then each Party may the conduct its own defense of such Claim and reserves the right to claim indemnification (to the extent provided for in Section 8.2) from the other Party upon resolution of the underlying Claim.

	8.4		Insurance. Each Party shall maintain insurance against all foreseeable risks and claims arising from its performance of activities licensed hereunder.

	8.5		Limitation of Liability. EXCEPT TO THE EXTENT A PARTY MAY BE REQUIRED TO INDEMNIFY THE OTHER FOR AMOUNTS PAID TO THIRD PARTIES OR AS REGARDS A BREACH OF A CONFIDENTIALITY OBLIGATION, NEITHER PARTY (NOR ITS AFFILIATES) SHALL BE LIABLE TO THE OTHER PARTY (NOR ITS AFFILIATES) FOR PUNITIVE, EXEMPLARY, MULTIPLIED OR CONSEQUENTIAL DAMAGES (SUCH AS LOST PROFITS, OPPORTUNITY COSTS, MISSED BUSINESS OPPORTUNITIES, OR OTHER THINGS CAUSED BUT NOT PROXIMATELY CAUSED BY ANY BREACH OR DEFAULT UNDER THIS AGREEMENT, WHETHER THE THEORY OF LIABILITY IS GROUNDED IN CONTRACT, TORT (INCLUDING NEGLIGENCE) PRODUCT LIABILITY OR OTHERWISE). EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT TO SEEK SUCH DAMAGES.

Priority of Agreement. The Parties agree and acknowledge that this Agreement supersedes any and all prior written or oral agreements between the Parties and any of their affiliates concerning the subject matter of this Agreement.

The Letter of Intent shall not be used to interpret or deemed to limit or modify the terms of this Agreement. However, the Confidentiality Agreement will remain in effect and will not be superseded by this Agreement; provided, however, that information exchanged between the Parties

In the event of the occurrence of such a force majeure event, the Party unable to perform shall promptly notify the other Party. It shall further use its best efforts to resume performance as quickly as possible and shall suspend performance only for such period of time as is necessary as a result of the force majeure event

	9.7		Expenses. Each Party shall bear its own expenses, if not expressly agreed otherwise in this Agreement.

	9.8		Amendment and Waiver. This Agreement may be amended or modified only by a writing executed by each of the Parties. No waiver of any breach of this Agreement will be deemed to constitute a continuing waiver of any subsequent breach, whether of the same or of any other provision hereof.

	9.9		Severability. If any provision of this Agreement is held or found to be unenforceable, such provision shall be deemed severed and stricken from this Agreement, but the remainder of this Agreement shall under all circumstances remain in full force and effect. The Parties intend that even is a provision is found to be unenforceable and thus deemed severed and stricken from this Agreement, the remaining terms of this Agreement shall continue in effect in all cases, and there shall be no right to rescind or terminate this Agreement.

	9.10		Counterparts. This Agreement may be executed in multiple counterparts, each
