			ARTICLE 2.DEVELOPMENT AND COMMERCIALIZATION
		

		
			2.1.Development Obligations and Funding.  ProQR will use Commercially Reasonable Efforts to Develop the Licensed Product, to obtain the required Regulatory Approvals for the Licensed Product and to Commercialize the Licensed Product in the United States, including taking the actions and meeting the timelines set forth in the Strategic Plan.  ProQR will be solely responsible for all costs in connection with such Development and Commercialization activities and will ensure adequate funding for such activities.
		

		
			2.2.Development and Commercialization Plan.  Within [***] after the Effective Date, the Parties will mutually agree, through the JSC, on a strategic development and commercialization plan (the “Strategic Plan”).  The Strategic Plan will initially cover the Development activities ProQR will perform and will be attached to the JSC minutes.  As the Licensed Product moves closer to market, the Strategic Plan will be updated to outline key activities for obtaining Regulatory Approval for, and launch and Commercialization of the Licensed Product.  The Strategic Plan will be updated at least annually or earlier if new data or information becomes available that changes the strategy for, or otherwise materially affects, the Licensed Product.  ProQR will promptly provide Ionis with updates to the Strategic Plan.
		

		
			2.3.Development Timelines.  ProQR will perform the following Development activities for the Licensed Product on the following timelines:
		

		
			(i)within [***] from the Effective Date, submit an IND to the FDA;
		

		
			(ii)within [***] following IND approval, Initiate the first Proof of Concept Study;

			(iii)within [***] following the successful completion of a Proof of Concept Study, Initiate a Pivotal Clinical Study or extend the Proof of Concept Study into a Pivotal Clinical Study for such Licensed Product; and
		

		
			(iv)within [***] following successful completion of the Pivotal Clinical Study, file an NDA.
		

		
			2.4.Extension of Development Timelines.  If Development (e.g. safety issues) or regulatory issues arise which make the diligence milestones in Section 2.3 impossible for ProQR to achieve, then the Parties will meet to discuss in good faith and agree on a reasonable extension of the timeline.  A failure by ProQR to meet a deadline in Section 2.3 will not constitute a material breach of the Agreement for which Ionis may exercise its right to terminate under Section 7.3 as long as ProQR is using Commercially Reasonable Efforts to conduct the development program, is not otherwise in breach of this Agreement, and such failure is primarily caused by factors outside ProQR’s reasonable control.
		

		
			2.5.Governance.
		

		
			2.5.1JSC.  The Parties will establish a joint steering committee (“JSC”) within [***] after the Effective Date.  Ionis will have the right but not the obligation to participate in the JSC through the filing of an NDA by ProQR for the Licensed Product.  The JSC will have [***] representatives appointed by ProQR and [***] representatives appointed by Ionis.  The JSC will meet at least once each Calendar Quarter and each Party will be responsible for the costs of its own employees or consultants attending JSC meetings.  The JSC may hold meetings in person or by audio or video conference as determined by the JSC.
		

		
			2.5.2Decision Making.  The JSC will have no decision-making authority and will act as a forum for sharing information about the activities conducted by the Parties hereunder and as an advisory body, in each case only on the matters described in, and to the extent set forth in, this Agreement.
		

		
			2.5.3Term of the JSC. The JSC will dissolve upon the earliest of (a) filing an NDA for the Licensed Product, (b) a Change of Control of Ionis, where the entity holding a controlling interest is developing or commercializing a product that is reasonably likely to compete with the Licensed Product, and (c) acquisition by Ionis of an entity that is developing or commercializing a product that is reasonably likely to compete with the Licensed Product.
		

		
			2.5.4Reports.  Within [***] following the end of each Calendar Quarter beginning with the first Calendar Quarter after dissolution of the JSC, ProQR will deliver written reports to Ionis stating significant milestones achieved during the Calendar Quarter in connection with its obligations under Section 2.1,  Section 2.2 and Section 2.3, including without limitation, status of clinical studies of the Licensed Product, dates where applications for Regulatory Approval of the Licensed Product have been submitted and the dates of First Commercial Sale for the Licensed Product. Reports on these topics prepared by ProQR for internal management purposes will be sufficient to satisfy this

			obligation.  The reporting obligation in this Section 2.5.4 will cease the Calendar Quarter following NDA Approval.
		

		
			2.6.Alliance Managers.  Each Party will appoint a representative to act as its alliance manager under this Agreement (each an “Alliance Manager”) through the JSC.  Each Alliance Manager will be responsible for supporting the JSC. The roles and responsibilities of the Alliance Managers will be determined by the JSC.
		

		
			2.7.Regulatory Communications and Meetings for Products.
		

		
			2.7.1If requested by ProQR, Ionis will provide reasonable support to ProQR in its efforts to prepare INDs and pre-Regulatory Approval submissions to Regulatory Authorities, and correspondence in connection therewith, including by providing ProQR with such information concerning a Licensed Product or the Ionis antisense oligonucleotide chemistry platform. ProQR will provide the JSC (or Ionis as appropriate) with copies of documents and communications (including drafts thereof) prior to submitting to, and copies of documents and communications received from, Regulatory Authorities that (i) relate to the Development or Commercialization of a Licensed Product, subject to redaction of sensitive information that also relates to products that are not Licensed Products, or (ii) ProQR reasonably anticipates could materially impact Ionis’ antisense oligonucleotide chemistry platform in each case, for Ionis’ review and comment.  ProQR will reasonably consider all timely comments provided by Ionis to such documents and communications.
		

		
			2.7.2If requested by ProQR, Ionis will provide reasonable support to ProQR in its efforts to prepare for meetings ProQR has, or plans to have, with a Regulatory Authority regarding pre-Regulatory Approval or Regulatory Approval matters for a Licensed Product.  ProQR will provide the JSC (or Ionis as appropriate) with advance written notice of any meetings ProQR has that (i) relate to the Development or Commercialization of a Licensed Product, or (ii) directly relate to Ionis’ antisense oligonucleotide chemistry platform.  If a meeting relates to Ionis’ antisense oligonucleotide chemistry platform, then, provided that the relevant Regulatory Authority agrees, ProQR will allow Ionis to attend and participate in that portion of any such meetings (and any preparation therefor).  For all other meetings with a Regulatory Authority, the Parties will discuss and mutually agree on whether Ionis may attend such meetings as an observer under the direction of ProQR.
		

		
			2.8.Class Generic Claims.  To the extent ProQR intends to make any claims in a Licensed Product label or regulatory filing that are class generic to oligonucleotides, ProQR will provide the JSC (or Ionis as appropriate) with copies of such claims and regulatory filings in a timeframe that allows for review and comment by Ionis prior to submitting such claims and filings, and ProQR will give reasonable consideration to Ionis’ reasonable comments.
		

		
			2.9.Clinical Study Data Sharing.  ProQR will keep Ionis generally informed of the progress and status of each Clinical Study.  ProQR will notify Ionis in writing promptly after ProQR completes each Clinical Study.  Once the initial tables, listings and figures

			2.11.1Ionis maintains an internal database that includes information regarding the tolerability of its drug compounds, individually and as a class, including information discovered during non-clinical and clinical development (the “Ionis Internal ASO Safety Database”).  To maximize understanding of the safety profile and pharmacokinetics of Ionis compounds, ProQR will cooperate in connection with populating the Ionis Internal ASO Safety Database.  ProQR shall provide copies of all clinical safety information to Ionis that ProQR is required to report to the FDA upon or promptly following submission to the FDA.  In connection with any reported serious adverse event related or potentially related to a Licensed Product, ProQR will provide Ionis all serious adverse event reports, including initial, interim, follow-up, amended and final reports.  In addition, with respect to Licensed Products, ProQR will provide Ionis with copies of annual safety updates filed with each IND and the safety sections of any final Clinical Study reports within [***] following the date such information is filed or is available to ProQR, as applicable.  Furthermore, ProQR will promptly provide Ionis with any supporting data and answer any follow-up questions reasonably requested by Ionis.  All such information disclosed by ProQR to Ionis will be ProQR Confidential Information; provided, however, that so long as Ionis does not disclose the identity of a Licensed Product or ProQR’s identity, Ionis may disclose any such ProQR Confidential Information to (i) Ionis’ other partners pursuant to Section 2.11.2 below if such information is regarding class generic properties of antisense oligonucleotides, or (ii) any Third Party.  ProQR will deliver all such information to Ionis for the Ionis Internal ASO Safety Database to Ionis Pharmaceuticals, Inc., 2855 Gazelle Court, Carlsbad, California 92010, Attention: Chief Medical Officer (or to such other address/contact designated in writing by Ionis).  ProQR will also cause its Affiliates and Sublicensees to comply with this Section 2.11.1.
		

		
			2.11.2From time to time, Ionis utilizes the information in the Ionis Internal ASO Safety Database to conduct analyses to keep Ionis and its partners informed regarding class generic properties of antisense oligonucleotides, including with respect to safety.  As such, if and when Ionis identifies safety or other related issues that may be relevant to a Licensed Product (including any potential class-related toxicity), Ionis will promptly inform ProQR of such issues and provide the data supporting Ionis’ conclusions.  In addition, so long as ProQR has complied with its obligations under Section 2.11.1, and upon ProQR’s reasonable written request, Ionis will provide safety information from the Ionis Internal ASO Safety Database relating to information regarding class generic properties of antisense oligonucleotides as requested to facilitate the Development and registration of the Licensed Product.

ProQR shall pay to Ionis the corresponding Sales Milestone Payment within [***] after the end of the Calendar Quarter during which such Sales Milestone Event is achieved.
		

		
			5.4.Royalties.
		

		
			5.4.1Full Royalty Rate.  As partial consideration for the rights granted to ProQR hereunder, subject to the provisions of this Section 5.4.1 and Section 5.4.2, ProQR will pay to Ionis a twenty percent (20%) royalty on annual worldwide Net Sales during the Royalty Term (the “Full Royalty Rate”); [***].
		

		
			(a)ProQR will pay to Ionis royalties on Net Sales of Licensed Products arising from named patient and other similar programs under Applicable Laws, and ProQR will provide reports and payments to Ionis consistent with this ARTICLE 5.  No royalties are due on Net Sales of Licensed Products arising from compassionate use and other programs providing for the delivery of Licensed Product at no cost.  The sales of Licensed Products arising from named patient, compassionate use, or other similar programs will not be considered a First Commercial Sale for purposes of calculating the Full Royalty Rate and Full Royalty Term.
		

		
			5.4.2Application of Royalty Rates.  All royalties set forth under Section 5.4.1 are subject to the provisions of this Section 5.4.2, and are payable as follows:

			of First Commercial Sale of such Licensed Product until the latest of December 31 following (i) the date of expiration of the last Valid Claim within the Licensed Patents Covering the relevant Licensed Product in the country in which such Licensed Product is made, used or sold, and (ii) the date of expiration of the data exclusivity period conferred by the applicable Regulatory Authority in such country with respect to such Licensed Product (e.g., such as in the case of an orphan drug) (such royalty period, the “Full Royalty Term”).
		

		
			(b)Reduced Royalty Term.  ProQR will pay Ionis royalties on Net Sales of Licensed Products at the Reduced Royalty Rate during the Reduced Royalty Term.  The term “Reduced Royalty Term” means, on a country-by-country and Licensed Product-by-Licensed Product basis, the period commencing upon January 1 following the expiration of the Full Royalty Term in such country for such Licensed Product.
		

		
			i.On January 1 following the expiration of the Full Royalty Term, and on each of the first [***] of such date, the royalty rate for the relevant Licensed Product in the relevant country shall be reduced by [***] basis points from the royalty rate that was in effect during the previous [***] period (the “Reduced Royalty Rate”) so that, after the expiration of such [***] period, and subject to potential further adjustment in connection with the emergence of a Generic Product as follows in this section, the Reduced Royalty Rate will be [***] for such Licensed Product in such country.
		

		
			ii.In addition to the foregoing, in the event that a Generic Product form of a Licensed Product is approved for marketing and sold in a given country, the Reduced Royalty Rate for sales of such Licensed Product in such country will be subject to reduction as follows:
		

		
			-the then-current Reduced Royalty Rate (as determined in accordance with Section 5.4.2(b)i as applicable) shall apply for the Calendar Year during which such Generic Product is approved for marketing and sold,
		

		
			-the Reduced Royalty Rate for the next Calendar Year, and for succeeding Calendar Years, shall be determined by [***].
		

		
			-For example, if the Reduced Royalty Rate is [***] in a given Calendar Year and a Generic Product has launched in [***].
		

		
			5.5.Payments and Reports.  ProQR will pay all payments due under Section 5.4 within [***] after the close of each Calendar Quarter.

			thereto and the calculation of royalties due thereon, including country and the exchange rate used (the “Payment Report”).  Following the First Commercial Sale, if no royalties are payable in respect of a given Calendar Quarter, ProQR will submit a written report to Ionis so indicating, together with an explanation as to why no such royalties are payable.  In addition, beginning with the Calendar Quarter in which the First Commercial Sale of a Licensed Product occurs and for each Calendar Quarter thereafter, as soon as reasonably practicable but no later than [***] following the end of each such Calendar Quarter, ProQR will provide Ionis a [***] report estimating the total projected Net Sales of Licensed Products and the royalties payable to Ionis for such Calendar Quarter.
		

		
			5.6.Mode of Payment.  Unless otherwise indicated, all payments under this Agreement will be (i) payable in full in U.S. dollars, regardless of the country(ies) in which sales are made, (ii) made by wire transfer of immediately available funds to an account designated by Ionis in writing, and (iii) non-creditable, irrevocable and non-refundable.  Whenever for the purposes of calculating the royalties payable under this Agreement conversion from any foreign currency will be required, all amounts will first be calculated in the currency of sale and then converted into United States dollars by applying the monthly average rate of exchange calculated by using the foreign exchange rates published in Bloomberg during the applicable month starting two business days before the beginning of such month and ending two business days before the end of such month or any other exchange rate methodology in accordance with GAAP and consistently applied across all its products by ProQR or its Affiliates or Sublicensees, as applicable in reporting its Net Sales.
		

		
			5.7.Audits.  ProQR shall maintain full and true books of accounts and other records pertaining to the sale of Licensed Products in sufficient detail so that any payments to Ionis hereunder can be properly ascertained.  Such books and records shall be maintained by ProQR for a period of [***] from creation of individual records.  [***] business days’ prior written notice, and no more frequently than [***], ProQR shall, at the request of Ionis, permit an independent certified public accounting firm selected by Ionis to have access during ordinary business hours, to only such books and records as may be necessary to determine the correctness of any report or payment made under this Agreement.  Prior to any examination of ProQR’s books and records, such accounting firm will enter into a confidentiality agreement with ProQR that includes customary terms.  Ionis shall be responsible for expenses for the accounting firm initially selected by Ionis; provided,  however, that if Ionis’ accounting firm reasonably determines that payments have been understated by an amount equal to or greater than [***]  ([***]), for any Calendar Year, then ProQR will pay the reasonable fees of such accounting firm for such audit, in addition to remitting payments owed with interest thereon computed in accordance with Section 5.9, within [***] after the date on which such accounting firm provides its report to ProQR. The accounting firm shall disclose to Ionis and ProQR only whether the Payment Reports are correct or not and, if applicable, the specific details concerning any discrepancies.  All inspections made by Ionis hereunder shall be made no later than [***] after the Payment Report that is the subject of the investigation was due.

Ionis will provide ProQR with any and all tax forms that may be reasonably necessary for ProQR to lawfully not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty.  Following ProQR’s timely receipt of such tax forms from Ionis, ProQR will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if appropriate under the applicable laws.  Ionis will provide any such tax forms to ProQR upon request and in advance of the due date.

			the first right, at its cost and expense, to file, prosecute, maintain and enforce throughout the world all Ionis Product-Specific Patents.  ProQR will provide Ionis with an update of the filing, prosecution, and maintenance status for each such Ionis Product-Specific Patent on a periodic basis.  ProQR or its outside counsel will provide to Ionis a right to comment on drafts prior to filing and copies of any material papers relating to the filing, prosecution, and maintenance of such Ionis Product-Specific Patents promptly upon their being filed or received.  If ProQR determines that it is not commercially reasonable to continue prosecuting or maintaining particular applications or patents within such Ionis Product-Specific Patents in selected jurisdictions, then ProQR may cease such efforts (in which case the terms of Section 6.3.5 will apply).
		

		
			6.3.3Ionis Sole Right.  Ionis will have the sole right, at its cost and expense and at its discretion, to file, prosecute, maintain, and enforce throughout the world the (a) Ionis Core Technology Patents and (b) Ionis Manufacturing and Analytical Patents.

			6.4.2Product-Specific Patents.  ProQR will have the first right, but not the obligation, at ProQR’s expense, to enforce the Ionis Product-Specific Patents against any such Competitive Infringement of an Ionis Product-Specific Patent.  If Ionis requests that ProQR take action to enforce any Ionis Product-Specific Patent against a Competitive Infringement, and ProQR believes that it is not commercially appropriate to take such actions, then the Parties will meet and discuss in good faith such circumstances and seek to reach agreement on what appropriate steps to take to cause such infringement to end in a commercially appropriate manner.  If the Parties cannot reach such agreement or ProQR fails to take steps to remove such infringement within [***] following notice of such infringement and a written request from Ionis to take action to remove such infringement, or earlier notifies Ionis in writing of its intent not to take such steps, Ionis will have the right to do so at its expense and ProQR will have the right, at its own expense, to be represented in any such action.

If Ionis requests that ProQR take action to defend such Ionis Product-Specific Patent against such challenge, and ProQR believes that it is not appropriate to defend, then the Parties will, within [***] from the filing date of the challenging notice or petition, meet and discuss in good faith such circumstances and seek to reach agreement on what appropriate steps to take.  If the Parties cannot reach such agreement or ProQR decides not to take steps to respond to the challenge, or earlier notifies Ionis in writing of its intent not to take such steps, Ionis will have the right to do so at its expense and ProQR will have the right, at its own expense, to be represented in any such action.  Ionis as the owner of the Ionis Product-Specific Patent, will be permitted to join the challenge proceedings and any communications between the Parties will be governed by the common interest privilege.
		

		
			6.4.3Ionis Core Technology Patents.  If the Parties learn that a Third Party is infringing one or more Valid Claims of an Ionis Core Technology Patent by selling a Competing Product (including any Competitive Infringement) and such infringement is likely to have a material adverse effect on the Licensed Product, then Ionis will have the sole right, but not the obligation, at Ionis’ expense, to enforce the Ionis Core Technology Patents against any such Competitive Infringement. If ProQR requests that Ionis take action to enforce any Ionis Core Technology Patent against a Competitive Infringement, and Ionis believes that it is not commercially appropriate to take such actions, then the Parties will meet and discuss in good faith such circumstances and seek to reach agreement on what appropriate steps to take to cause such infringement to end in a commercially appropriate manner.

If any Third Party asserts in writing or in any legal proceeding that any of the Licensed Patents are unenforceable based on any term or condition of this Agreement, then the Parties shall amend this Agreement as may reasonably be required to effect the original intent of the Parties, including to preserve the enforceability of such Licensed Patents.
		

		
			6.4.5Recovery.  Any damages or other monetary awards recovered with respect to any action contemplated by this Section 6.4 will be shared as follows:
		

		
			(i)the amount of such recovery will first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then

Notwithstanding anything to the contrary under this ARTICLE 6, neither Party may enter a settlement, consent judgment, or other voluntary final disposition of a Competitive Infringement matter under this ARTICLE 6 that disclaims, limits the scope of, admits the invalidity or unenforceability of, or grants a license, covenant not to sue or similar immunity under a Patent Controlled by the other Party without first obtaining the written consent of the Party that Controls the relevant Patent.
		

		
			6.4.735 USC 271(e)(2) Infringement.  Notwithstanding anything to the contrary in this Section 6.4, solely with respect to the Licensed Patents for a Competitive Infringement under 35 USC 271(e)(2), the time period set forth in Section 6.4.2 during which a Party will have the initial right to bring a proceeding will be shortened to a total of 25 days, so that, to the extent the other Party has the right pursuant to Section 6.4.2 to initiate a proceeding against such a Competitive Infringement if the first Party does not initiate such a proceeding within [***] after such first Party’s receipt of written notice of such Competitive Infringement, such other Party will have such right.

			7.7.8Transition Activities
		

		
			(a)The Parties wish to provide a mechanism to ensure that, assuming the Discontinued Product is available to patients as of the reversion date, patients who were being treated with the Discontinued Product prior to such termination or who desire access to the Discontinued Product can continue to have access to such Discontinued Product while the regulatory and commercial responsibilities for the Discontinued Product are transitioned from ProQR to Ionis. As such, Ionis may request ProQR to perform transition activities that are necessary or useful to (1) transition ProQR’s Commercialization activities (if any) to Ionis to minimize disruption to sales, (2) provide patients with continued access to the applicable Discontinued Products (if applicable), (3) enable Ionis (or Ionis’ designee) to assume and execute the responsibilities under all Regulatory Approvals and ongoing Clinical Studies for the applicable

			Discontinued Product, and (4) ensure long-term continuity of supply for the Discontinued Product (collectively, the “Transition Activities”), including, if applicable, the categories of services and deliverables listed on SCHEDULE 7.7.8(a), but no longer than [***] following the effective date of termination. If applicable, ProQR will perform such Transition Activities using commercially reasonable efforts for the periods set forth in SCHEDULE 7.7.8(a); provided ProQR and Ionis may mutually agree in writing to conduct the Transition Activities for a longer period of time.
		

		
			(b)Ionis may elect to have ProQR perform the applicable Transition Activities by providing written notice to ProQR no later than [***] following the effective date of the termination. If Ionis requests Transition Activities, without limiting the provisions of Section 7.7.8, the Parties will mutually agree upon a transition plan for ProQR to perform the applicable Transition Activities including delivery and transition dates. In addition, the Parties will establish a transition committee consisting of at least each Party’s Alliance Managers, a representative from each Party’s chemistry, manufacturing and controls (CMC) group who was responsible for the Discontinued Product prior to the termination, and up to [***] additional representatives from each Party who are from other relevant functional groups to facilitate a smooth transition. While ProQR is providing applicable Transition Activities, ProQR and Ionis will agree on talking points and a communication plan to customers, specialty pharmacies, physicians, regulatory authorities, patient advocacy groups, and clinical study investigators, in each case only if applicable at the time of reversion, and ProQR will make all such communications to such applicable entities in accordance with the mutually agreed talking points.
		

		
			(c)Ionis will [***] to perform the Transition Activities, [***]. In addition, Ionis will [***] to perform the Transition Activities. Ionis will own all revenue derived from the Discontinued Product after the termination date and ProQR will remit all such revenues to Ionis no later than the [***] following the end of the month in which such revenue was received.
		

		
			7.8.ProQR’s Right of Setoff.  Notwithstanding any other provisions of this Agreement, if ProQR has the right to terminate this Agreement under Section 7.3 (including expiration of all applicable cure periods thereunder), and ProQR does not wish to terminate this Agreement, then, in lieu of any termination right ProQR may have under this Agreement or otherwise, ProQR may setoff against any amounts owed to Ionis pursuant to ARTICLE 5 (Financials) solely with respect to the Licensed Product that is the subject of the breach [***] (the “Setoff Amount”).  If ProQR exercises its setoff right under this Section 7.8, ProQR will provide Ionis with a written certificate, signed by ProQR’s Chief Financial Officer, certifying [***].  Notwithstanding the foregoing, if Ionis notifies ProQR in writing (a “Setoff Dispute Notice”) that it disputes ProQR’s assertion that Ionis is in material breach of this Agreement or the amount setoff by ProQR (a “Setoff Dispute”), then (a) both Parties will participate in the dispute resolution process set forth in SCHEDULE 7.8, and (b) pending the Parties’ agreement regarding the appropriate setoff (if

			any) or a determination by the Advisory Panel of the proper amount that ProQR may setoff (if any) in accordance with SCHEDULE 7.8, ProQR will pay the Setoff Amount into an interest-bearing escrow account established for the purpose at a bank.  If the Parties cannot settle their dispute by mutual agreement, then, in accordance with SCHEDULE 7.8 the Advisory Panel will determine (i) the amount (if any) that ProQR may setoff against future payments solely with respect to the Licensed Product that is the subject of the breach to Ionis going forward, and (ii) whether any portion of the escrow account should be released to Ionis or returned to ProQR, provided that any decision or determination by the Advisory Panel (a “Panel Decision”) will not be treated as an arbitral award but will be binding on the Parties until and unless arbitrators appointed in accordance with Section 12.2.2(a) (the “Arbitrators”) have determined in an arbitration award regarding some or all of the issues decided in the Panel Decision, and in any action contemplated by the next sentence hereof the Arbitrators will determine the facts and the law de novo, and will give a Panel Decision only such persuasive effect, if any, that after review of all of the facts and the law presented to the Arbitrators by the Parties, the Arbitrators deem appropriate, provided that the escrow agent will comply with a Panel Decision that determines that any portion of the escrow account should be released to Ionis or returned to ProQR.  If it is determined in an award by the Arbitrators that Ionis owes ProQR any damages, then, [***].  If the Arbitrators determine that ProQR has setoff an amount that exceeds the amount of losses, damages and expenses actually incurred by ProQR as a result of Ionis’ breach of this Agreement, then ProQR will promptly pay to Ionis the amount of such excess, plus interest on such amount as provided for in Section 5.9 (Interest), with interest accruing from the time ProQR applied such excess setoff.  If, with respect to a Setoff Dispute, Ionis provides a Setoff Dispute Notice to ProQR and ProQR fails to do any of the following:  (1) appoint a member of the Advisory Panel to the extent required in Section 2 of SCHEDULE 7.8; (2) meet with the Advisory Panel as required in Section 3 of SCHEDULE 7.8; or (3) pay the Setoff Amount into an interest-bearing escrow account established for the purpose at a bank, then ProQR will forfeit its right to setoff under this Section 7.8 and SCHEDULE 7.8 with respect to any and all Setoff Disputes.

Regarding any proposed scientific or clinical publications or public presentations related to summaries of results from any of the activities under this Agreement generated by Ionis or ProQR, the Parties acknowledge that scientific lead time is a key element of the value under this Agreement and further agree to use Commercially Reasonable Efforts to control public scientific disclosures of the results of the activities under this Agreement to prevent any potential adverse effect of any premature public disclosure of such results.  The Parties will agree to a publication plan whereby each Party will first submit to the other Party an advanced draft of all such publications or presentations, whether they are to be presented orally or in written form, at least [***] prior to submission for publication. Each Party will review such proposed publication in order to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of any Know-How arising under this Agreement.

			CONFIDENTIAL TREATMENT REQUESTED

		





 



		

		
			 
		

		
			Annex E
		

		
			 
		

		
			BASEBALL ARBITRATION
		

		
			 
		

		
			1.The Parties shall select and agree upon a mutually acceptable independent Third Party expert who is neutral, disinterested and impartial, and has significant relevant experience in the commercialization of pharmaceutical products (the “Expert”).  If the Parties are unable to promptly agree upon an Expert, then upon request by either Party, the Expert shall be an arbitrator appointed by the American Arbitration Association (“AAA”).  The date on which such arbitrator is selected will be the “Arbitration Commencement Date.”  Each Party shall within ten (10) days following the Arbitration Commencement Date prepare and deliver to both the Expert and the other Party its proposed terms to resolve the disputed matter (i.e., the allocation of the relative contribution of the Licensed Product and each other device or active ingredient to a particular Combination Product) and a memorandum (the “Supporting Memorandum”) in support thereof.  The Expert will also be provided with a copy of this Agreement.  Within ten (10) days after receipt of the other Party’s Supporting Memorandum, each Party may submit to the Expert (with a copy to the other Party) a rebuttal to the other Party’s Supporting Memorandum (a “Rebuttal”), which may include a revision, marked to show changes, of either Party’s proposed terms.  Neither Party may have ex parte communications (either written or oral) with the Expert other than for the sole purpose of engaging the Expert or as expressly permitted in this Annex E.
		

		
			2.Within twenty (20) days after the Expert’s receipt of each Party’s Rebuttal (or the expiration of the period for the Parties to submit a Rebuttal, if earlier), the Expert will select, between the proposals provided by the Parties, the proposal that the Expert believes most accurately reflects an equitable result for the Parties consistent with the principles set forth in Section 1.1.71 (the “Selected Allocation”).  The Expert shall not have the authority to modify a proposal initially submitted by a Party.  The decision of the Expert shall be the sole, exclusive and binding remedy and the Selected Allocation shall become a binding and enforceable agreement between the Parties.

			1.If ProQR has exercised its setoff right under Section 7.8 (ProQR’s Right of Setoff) and there is a Setoff Dispute, then the Parties will convene an Advisory Panel in accordance with the procedures set forth below (the “Advisory Panel”).
		

		
			2.Ionis and ProQR will negotiate in good faith to, within [***] after Ionis delivers the Setoff Dispute Notice to ProQR, identify a single expert having the Qualifications set forth below to act as the Advisory Panel; provided that if the Parties cannot identify a mutually agreed expert within such [***], then the Advisory Panel will have [***] members, who will be selected as follows: each of ProQR, on the one hand, and Ionis on the other hand, will appoint [***] member of the Advisory Panel within [***] after Ionis delivers the Setoff Dispute Notice to ProQR, and those two Party-appointed members will unanimously select the [***] member (who will act as chairperson of the Advisory Panel) within [***] of the appointment of the last Party-appointed member. If the Party-appointed members cannot agree upon the selection of the [***] member within such [***] period, the Parties will immediately jointly ask the AAA to appoint such chairperson, such appointment to be made within [***] of such request, in accordance with Rule R-13(a) of the AAA Commercial Arbitration Rules in effect as of the date of the Agreement (the “AAA Rules”). Each of the members of the Advisory Panel, whether appointed by a Party or by the AAA, will have the following qualifications (as applicable, the “Qualifications”): (i) in all cases cannot be a current or former employee, officer or director of either Party, or its Affiliates or a current consultant or independent contractor of either Party or its Affiliates; (ii) if the claimed material breach by Ionis primarily involves ownership, prosecution and maintenance, defense or enforcement of intellectual property or rights therein, the Qualifications are to be an attorney who has practiced United States patent law for at least [***]; (iii) if the claimed material breach by Ionis primarily involves Section 4.5 of the Agreement (Exclusivity), the Qualifications are to be an attorney who is admitted to practice law with at least [***] of experience advising Persons on pharmaceutical drug development and commercialization; and (iv) for any other claimed material breach by Ionis, the Qualifications are to be an attorney who has been admitted to practice law in for at least [***] and who has significant experience in the pharmaceutical industry. In addition, (1) if the chairperson is appointed by the AAA, AAA Rules R-16 and R-17 will apply to the selection of such chairperson and (2) the chairperson, or the single expert agreed upon pursuant to this Section 2 of this SCHEDULE 7.8, must be an attorney who is admitted to practice law in the State of Delaware with at least [***] of experience.
		

		
			3.The Parties will meet with the Advisory Panel in person in Dover, Delaware (the “Resolution Meeting”) on a mutually agreed-upon date no earlier than [***] and no later

			(a)Whether the amount placed in escrow by ProQR pursuant to Section 7.8 exceeds the Advisory Panel’s objective good faith estimate of the amount of any losses, damages and expenses incurred or likely to be incurred by ProQR as a result of Ionis’ breach of the Agreement; and
		

		
			(b)What amount (if any) may ProQR setoff against future payments to Ionis under Section 7.8, which amount will represent the Advisory Panel’s objective good faith estimate of the amount of any losses, damages and expenses incurred or likely to be incurred by ProQR as a result of Ionis’ breach of the Agreement.
		

		
			9.If the Advisory Panel determines that the amount placed in escrow by ProQR pursuant to Section 7.8 exceeds the Advisory Panel’s objective good faith estimate of the amount of any losses, damages and expenses incurred or likely to be incurred by ProQR as a result of Ionis’ breach of the Agreement, the Parties will promptly cause the escrow agent to release to Ionis the amount of such excess, plus interest accruing on such amount in the escrow account. The Parties will promptly cause the remaining amount in the account to be returned to ProQR.
