2. LICENSE

2.1 Grant of License.

(a) Subject to the terms of this Agreement and Hospital’s retained rights in the Patent Rights as set forth in Section 2.3, Hospital hereby grants to Company in the License Field in the License Territory:

(i) an exclusive, royalty-bearing license under its rights in Patent Rights to make, have made, use, have used, Sell and have Sold Products and Processes; and

(ii) the right to grant sublicenses under the rights granted in Section 2.1(a)(i) to Sublicensees, provided that in each case Company shall be responsible for the performance of any obligations of Sublicensees relevant to this Agreement as if such performance were carried out by Company itself, including, without limitation, the payment of any royalties or other payments provided for hereunder, regardless of whether the terms of any sublicense provide for such amounts to be paid by the Sublicensee directly to Hospital.

(b) The license granted in Section 2.1(a) above includes:

(i) the right to grant to the final purchaser, user or consumer of Products the right to use such purchased Products in a method coming within the scope of Patent Rights within the License Field and License Territory; and

(ii) the right to grant a Distributor the right to Sell (but not to make, have made, use or have used) such Products and/or Processes for or on behalf of Company, its Affiliates and Sublicensees in a manner consistent with this Agreement.

(c) The foregoing license grant shall include the grant of such license to any Affiliate of Company, provided that such Affiliate shall assume the same obligations as those of Company and be subject to the same terms and conditions hereunder; and further provided that Company shall be responsible for the performance of all of such obligations and for compliance with all of such terms and conditions by Affiliate. Company shall provide to Hospital a fully signed, non-redacted copy of each agreement pursuant to which each such Affiliate assumes the aforesaid obligations, including all exhibits, attachments and related documents and any amendments, within thirty (30) days of Company’s receipt of a written request by Hospital.

2.2 Sublicenses. Each sublicense granted hereunder shall be consistent with and comply with all terms of this Agreement, shall incorporate terms and conditions sufficient to enable Company to comply with this Agreement, shall prohibit any further sublicense or assignment by a Sublicensee without Hospital consent and shall provide that Hospital is a third party beneficiary thereof. For the limited purpose of facilitating Hospital’s good faith evaluation

of potential conflicts of interests, Company shall provide written notification to Hospital, in confidence, of the identity of any third party that Company is engaging in discussions with towards a sublicense prior to entering into a binding agreement between Company and such third party. Hospital shall promptly (but in no event longer than fifteen (15) business days following Hospital’s receipt of Company’s written notice) notify Company if Hospital does not approve of such third party as potential Sublicensee because of an actual conflict of interest, and Hospital shall provide rationale to Company for such action. Company shall provide to Hospital a fully signed non-redacted copy of all sublicense agreements and amendments thereto, including all exhibits, attachments and related documents, within thirty (30) days of executing the same; provided, however, that for the purposes of this Agreement, such copy of the sublicense agreements shall be considered the Confidential Information of Company and the applicable Sublicensee, and shall be treated in accordance with the provisions of Appendix D. Upon termination of this Agreement or any license granted hereunder for any reason, any sublicenses shall be addressed in accordance with Section 10.7. Any sublicense which is not in accordance with the forgoing provisions shall be null and void.

2.3 Retained Rights; Requirements. Any and all licenses granted hereunder are subject to:

(a) the right of Hospital, Hospital’s Affiliates and academic, government and not-for-profit institutions to make and to use the subject matter described and/or claimed in the Patent Rights solely for internal research, and education purposes; and

(b) for Patent Rights supported by federal funding, the rights, conditions and limitations imposed by U.S. law (see 35 U.S.C. § 202 et seq. and regulations pertaining thereto), including without limitation:

(i) the royalty-free non-exclusive license granted to the U.S. government; and

(ii) the requirement that any Products used or sold in the United States shall be manufactured substantially in the United States.

2.4 No Additional Rights. It is understood that nothing in this Agreement shall be construed to grant Company or any of its Affiliates a license, express or implied, under any patent owned solely or jointly by Hospital other than the Patent Rights expressly licensed hereunder. Subject to Section 2.5, Hospital shall have the right to license any Patent Rights to any other party for any purpose outside of the License Field or the License Territory.

2.5 License Outside the License Field; Notice.

(a) License outside the License Field. When Company wishes to license any therapeutic indication falling under the Patent Rights but outside the License Field, it will

approach Hospital with such request. Such request by Company shall be accompanied by a development plan that demonstrates that the Company has sufficient resources to commercially develop a therapeutic indication outside the License Field. Hospital would then engage in good faith negotiations with Company to license the additional field in substantially the same terms as those of this Agreement. If Parties cannot reach agreement after such good faith negotiations, Hospital shall be free to license the fields outside of License Field to any party on any terms as it sees fit; provided, however, that for a period of six (6) months thereafter Hospital agrees not to enter into a binding agreement with any third party on materially better terms than those last offered to Company without first offering such terms to Company, in which case Company will have thirty (30) days within which to accept or reject such terms.

(b) Notice. Hospital shall use reasonable efforts to provide written notification to Company for a period of twelve (12) months from the Effective Date, in confidence, in the event that any third party engages Hospital in substantive discussions to license the fields outside of the License Field at least thirty (30) days prior to entering into a binding agreement between Hospital and such third party. Hospital shall use reasonable efforts to respond in good faith to any written requests received from Company inquiring whether Hospital is then engaged in substantive discussions to license, or has otherwise licensed to any third party, one or more fields outside of the License Field.

3. DUE DILIGENCE OBLIGATIONS

3.3 Diligence Failures.

(a) If Company envisages that it will fail to meet one of the obligations under Section 3.1, it will notify Hospital at least three (3) months before the respective obligation is due.

(ii) 2 year delay [***] (i.e., [***] for 2^nd year of failure, if [***] for 1^st year of extension has already been paid);

(iii) 3 year delay [***] (i.e., [***] for 3^rd year of failure, if [***] for 1^st year of extension and [***] for 2^nd year of extension has already been paid); and

(b) Hospital’s determination regarding granting the above mentioned diligence extensions, as well as Hospital’s right to terminate this Agreement in the event that Company fails to meet any of its obligations under Section 3.1 shall be guided by the level of continued commitment by Company to bring a Product or Process to the market, the ability of Company relative to alternate opportunities available to Hospital to bring Products and Processes to the market to benefit patients, and by the level investment of money that Company has made in Hospital’s Patent Rights.

(c) Subject to Section 3.2(b), if Hospital determines that Company has failed to fulfill any of its obligations under Section 3.1, then Hospital may treat such failure as a default and may terminate this Agreement and/or any license granted hereunder in accordance with Section 10.4.

Company agrees to indemnify, defend and hold Hospital harmless from and against any and all liabilities, damages, costs and expenses arising from the failure of Company to timely pay such invoices and Patent Costs. Hospital shall instruct its designated patent counsel to provide copies

to Hospital for Hospital’s administrative files of all invoices detailing Patent Costs which are sent directly to Company.

7. THIRD PARTY INFRINGEMENT AND LEGAL ACTIONS

7.1 Hospital Right to Prosecute. Hospital will protect its Patent Rights from infringement and prosecute infringers when, in its reasonable sole judgment, such action may be reasonably necessary, proper and justified. If Company shall have supplied Hospital with written evidence demonstrating to Hospital’s reasonable satisfaction prima facie infringement of a claim of a Patent Right in the License Field in the License Territory by a third party which poses a material threat to Company’s rights under this Agreement, Company may by notice request Hospital to take steps to protect such Patent Right. Hospital shall use reasonable efforts to notify Company within one (1) month of the receipt of such notice whether Hospital intends to prosecute the alleged infringement. If Hospital notifies Company that it intends to so prosecute, Hospital shall, within one (1) month of its notice to Company (or sooner if so required by statute or law) either (i) cause such infringement to terminate, or (ii) initiate legal proceedings against the infringer.

7.2 Company Right to Prosecute. In the event Hospital notifies Company that Hospital does not intend to prosecute infringement identified under Section 7.1, Company may, upon notice to Hospital, initiate legal proceedings against the infringer at Company’s expense with respect to a claim of a Patent Right in the License Field in the License Territory. Before commencing such action, Company and, as applicable, any Affiliate, shall consult with Hospital, concerning, among other things, Company’s standing to bring suit, the advisability of bringing suit, the selection of counsel and the jurisdiction for such action (provided Company must have Hospital’s prior written consent with respect to selection of jurisdiction for any action in which Hospital may be joined as a party-plaintiff) and shall use reasonable efforts to accommodate the views of Hospital regarding the proposed action, including without limitation with respect to potential effects on the public interest. Company shall be responsible for all costs, expenses and liabilities in connection with any such action and shall indemnify and hold Hospital harmless therefrom, regardless of whether Hospital is a party-plaintiff, except for the expense of any independent counsel retained by Hospital in accordance with Section 7.5 below.

7.3 Hospital Joined as Party-Plaintiff. If Company elects to commence an action as described in Section 7.2 above, Hospital shall have, in its sole discretion, the option to join such action as a party-plaintiff. If Hospital is required by law to join such action as a party-plaintiff, Hospital may either, in its sole discretion, permit itself to be joined as a party-plaintiff at the sole expense of Company, or assign to Company all of Hospital’s right, title and interest in and to the Patent Right which is the subject of such action (subject to all of Hospital’s obligations to the government under law and any other rights that others may have in such Patent Right). If

Hospital makes such an assignment, such action by Company shall thereafter be brought or continued without Hospital as a party; provided, however, that Hospital shall continue to have all rights of prosecution and maintenance with respect to Patent Rights and Company shall continue to meet all of its obligations under this Agreement as if the assigned Patent Right were still licensed to Company hereunder.

7.4 Notice of Actions; Settlement. Company shall promptly inform Hospital of any action or suit relating to Patent Rights and shall not enter into any settlement, consent judgment or other voluntary final disposition of any action relating to Patent Rights, including but not limited to appeals, without the prior written consent of Hospital, such consent not to be unreasonably withheld, delayed or conditioned.

7.5 Cooperation. Each Party agrees to cooperate reasonably with the other Party in any action under Section 7 which is controlled by the other Party, provided that the controlling party reimburses the cooperating party for any out-of-pocket costs and expenses incurred by the cooperating party in connection with providing such assistance, except for the expense of any independent counsel retained by the cooperating party in accordance with this Section 7.5. Such controlling party shall keep the cooperating party informed of the progress of such proceedings and shall make its counsel available to the cooperating party. The cooperating party shall also be entitled to independent counsel in such proceedings but at its own expense, said expense to be offset against any damages received by the Party bringing suit in accordance with Section 7.6.

7.6 Recovery. Any award paid by third parties as the result of proceedings contemplated by this Section 7 (whether by way of awarded damages, settlement or otherwise) shall first be applied to reimbursement of any legal fees and expenses incurred by either Party and then the remainder shall be divided between the Parties as follows:

(a) (i) Company shall receive an amount equal to its lost profits or a reasonable royalty

(ii) on the infringing sales, or whichever measure of damages the court shall have applied; and

(iii) Hospital shall receive an amount equal to the royalties and other amounts that Company would have paid to Hospital if Company had Sold the infringing Products and Services rather than the infringer; and

(b) the balance, if any, remaining after Company and Hospital have been compensated under Section 7.6(a) shall be shall be shared equally by the Parties.

8. INDEMNIFICATION AND INSURANCE

8.1 Indemnification.

(a) Company shall indemnify, defend and hold harmless Hospital and its Affiliates and their respective trustees, directors, officers, medical and professional staff, employees, and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss or expense (including reasonable attorney’s fees and expenses of litigation) incurred by or imposed upon the Indemnitees or any one of them in connection with any claims, suits, actions, demands or judgments arising out of any theory of product liability (including, but not limited to, actions in the form of contract, tort, warranty, or strict liability) concerning any Product or Process made, used, or sold or performed pursuant to any right or license granted under this Agreement.

(b) To receive the benefit of indemnification under Section 8.1 (a), the Indemnitees must: (i) promptly notify Company of the claim, suit, action, demand or judgment for which indemnification is being sought; provided, that failure to give such timely notice shall not relieve Company of its indemnification obligations; (ii) provide reasonable cooperation with the Company; and (iii) tender to Company full authority to defend such claim, suit, action, demand or judgment. Company agrees, at its own expense, to provide attorneys reasonably acceptable to the Hospital to defend against any actions brought or filed against any Indemnitees with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought.; provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of Company, if representation of such Indemnitee by counsel retained by Company would be inappropriate because of conflict of interests of such Indemnitee and any other party represented by such counsel. Company agrees to keep Hospital informed of the progress in the defense and disposition of such claim and to consult with Hospital prior to any proposed settlement.

8.2 Insurance.

(a) Beginning at such time as any Product and/or Process is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company, an Affiliate or Sublicensee, Company shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate and naming the Indemnitees as additional insureds. Such commercial general liability insurance shall provide (i) product liability coverage and (ii) broad form contractual liability coverage for Company’s indemnification under Section 8.1 of this Agreement. If Company elects to self-insure all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate) such self-insurance program must be acceptable to the Hospital and the Risk Management Foundation. The minimum amounts of insurance coverage required under this Section 8.2 shall not be construed to create a limit of Company’s liability with respect to its indemnification under Section 8.1 of this Agreement.

(b) Company shall provide Hospital with written evidence of such insurance upon request of Hospital. Company shall provide Hospital with written notice at least fifteen (15) days prior to the cancellation, non-renewal or material change in such insurance; if Company does not obtain replacement insurance providing comparable coverage prior to the expiration of such fifteen (15) day period, Hospital shall have the right to terminate this Agreement effective at the end of such fifteen (15) day period without notice or any additional waiting periods.

(c) Company shall maintain such commercial general liability insurance beyond the expiration or termination of this Agreement during (i) the period that any such Product or Process is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company or by a Sublicensee or Affiliate of Company and (ii) a reasonable period after the period referred to in (c) (i) above which in no event shall be less than ten (10) years.

(d) This section 8.2 shall survive expiration or termination of this Agreement.

9. DISCLAIMER OF WARRANTIES; LIMITATION OF LIABILITY

9.1 Title to Patent Rights. To the best knowledge of Hospital’s Office of Research, Ventures and Licensing, Hospital (i) is the owner of the Patent Rights, and (ii) has sufficient rights and the authority to enter into this Agreement and license the Patent Rights to Company hereunder.

9.2 No Warranties. HOSPITAL MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, CONCERNING THE PATENT RIGHTS AND THE RIGHTS GRANTED HEREUNDER, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, VALIDITY OF PATENT RIGHTS CLAIMS, WHETHER ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AND HEREBY DISCLAIMS THE SAME.

9.3 Limitation of Liability. IN NO EVENT SHALL EITHER PARTY OR ANY OF THEIR RESPECTIVE AFFILIATES OR ANY OF THEIR RESPECTIVE TRUSTEES, DIRECTORS, OFFICERS, MEDICAL OR PROFESSIONAL STAFF, EMPLOYEES AND AGENTS BE LIABLE TO THE OTHER PARTY OR ANY OF ITS AFFILIATES, OR AS APPLICABLE ITS SUBLICENSEES OR DISTRIBUTORS FOR INDIRECT, SPECIAL,

INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND ARISING IN ANY WAY OUT OF THIS AGREEMENT OR THE LICENSE OR RIGHTS GRANTED HEREUNDER, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, INCLUDING WITHOUT LIMITATION ECONOMIC DAMAGES OR INJURY TO PROPERTY OR LOST PROFITS, REGARDLESS OF WHETHER SUCH PARTY SHALL BE ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING, PROVIDED, HOWEVER, NOTHING IN THIS SECTION 9.3 SHALL BE CONSTRUED TO LIMIT COMPANY’S OBLIGATION TO INDEMNIFY HOSPITAL UNDER SECTION 8 OF THIS AGREEMENT.

12.3 Amendment; Waiver.

The failure of either Party at any time or times to require performance of any provision hereof shall in no manner affect its rights at a later time to enforce the same.

CONFIDENTIALITY TERMS AND CONDITIONS

1. Definition of Confidential Information. “Confidential Information” shall mean any information, including but not limited to data, techniques, protocols or results, or business, financial, commercial or technical information, disclosed by one Party (each a “Discloser” as applicable) to the other Party (each a “Recipient” as applicable) in connection with the terms of that certain Exclusive License Agreement dated May 29, 2012 (the “License Agreement”) and identified as confidential at the time of disclosure (the “Purpose”). Hospital’s Confidential Information shall also include all information disclosed by Hospital to Company in connection with the Patent Rights. Capitalized terms used in this Appendix that are not otherwise defined herein have the meanings ascribed in the License Agreement to which this Appendix is attached and made a part thereof.

2. Exclusions. “Confidential Information” shall not include any information that (i) is or becomes publicly available through no wrongful act of Recipient; (ii) was known by Recipient prior to disclosure by Discloser, as evidenced by tangible records; (iii) becomes known to Recipient after disclosure from a third party having an apparent bona fide right to disclose it; (iv) is independently developed or discovered by Recipient without use of Discloser’s Confidential Information, as evidenced by tangible records; or (v) is disclosed to another party by Discloser without restriction on further disclosure. The obligations of confidentiality and non-use set forth herein shall not apply with respect to any information that Recipient is required to disclose or produce pursuant to applicable law, court order or other valid legal process provided that Recipient promptly notifies Discloser prior to such required disclosure, discloses such information only to the extent so required and cooperates reasonably with Discloser’s efforts to contest or limit the scope of such disclosure.

3. Permitted Purpose. Recipient shall have the right to, and agrees that it will, use Discloser’s Confidential Information solely for the Purpose as described in the License Agreement, except as may be otherwise specified in a separate definitive written agreement negotiated and executed between the parties.

Recipient may, however, disclose Discloser’s Confidential Information only on a need-to-know basis to its and its Affiliates employees, staff members and agents (“Receiving Individuals”) who are directly

participating in the Purpose and who are informed of the confidential nature of such information, provided Recipient shall be responsible for compliance by Receiving Individuals with the terms of this Agreement and any breach thereof. This Section 4 shall survive termination or expiration of the License Agreement.

5. Right to Disclose. Discloser represents that to the best of its knowledge it has the right to disclose to each Recipient all of Discloser’s Confidential Information that will be disclosed hereunder.

6. Ownership. All Confidential Information disclosed pursuant to this Agreement, including without limitation all written and tangible forms thereof, shall be and remain the property of the Discloser. Upon termination of the License Agreement, if requested by Discloser, Recipient shall return or destroy at Discloser’s discretion all of Discloser’s Confidential Information, provided that Recipient shall be entitled to keep one copy of such Confidential Information in a secure location solely for the purpose of determining Recipient’s legal obligations hereunder.

7. No License. Nothing herein shall be construed as granting or conferring, expressly or impliedly, any rights by license or otherwise, under any patent, copyright, or other intellectual property rights owned or controlled by Discloser relating to Confidential Information, except as specifically set forth in the License Agreement.

8. Remedies. Each party acknowledges that any breach of this Agreement by it may cause irreparable harm to the other party and that each party is entitled to seek injunctive relief and any other remedy available at law or in equity.

9. General. These Confidentiality Terms and Conditions, along with the License Agreement, and that certain Non-Disclosure Agreement entered into by the Parties dated March 26, 2012 contain the entire understanding of the parties with respect to the subject matter hereof, and supersede any prior oral or written understandings between the parties relating to confidential treatment of information. Sections 1, 2, 4, 6, 7and 9 of these Confidentiality Terms and Conditions shall survive any expiration or termination of the License Agreement.

Commercialization Plan provided by Company

Strictly confidential | covered under CDA | disclosed to MGH

Company

ProQr is developing RNA-modulating therapeutics for genetic disorders for which there are no effective curative treatments. As such, ProQR has chosen to first develop a proof of concept in the field of cystic fibrosis (CF), a monogenic orphan drug indication. Their identified lead compound has achieved preclinical proof of principle for CF. In addition, ProQR has generated a robust pipeline using their proprietary technology platform, which corrects mutated messenger RNA (mRNA) at the source of disease and is broadly applicable to many genetic disorders.

ProQr currently operated in a virtual fashion and is based Leiden, The Netherlands. The Company is run by an experienced management team and Board, with expertise from world-class scientific/drug development advisors and strong investors.

Pursuing a Diversified Development and Commercialization Strategy

Because the patient populations in genetic disorders are generally small and well defined, ProQR intends to

keep all development and commercialization rights to the products within its core therapeutic focus and to

selectively out-license or spin-out other assets generated from its platform. ProQR intends to grow into a fully

integrated specialty pharmaceutical company in order to launch and sell its core products in the Western world.

Development

ProQR Therapeutics is actively developing the technology to the clinical proof-of-concept (PoC), for which the

following steps are defined:

Upcoming 4-Year Deliverables and Milestones

•

Completion of preclinical optimization studies for CF compounds in [***].

•

CMC, manufacturing for lead compound PQR-01 done in [***];

•

Toxicology program for PQR-01 finalized in [***];

•

Initiation of Phase I/II clinical proof of concept trial in [***]: with anticipated completion in [***]

Subsequent development has been planned but for the purpose of transparency is not part of this summary.

Strictly confidential | covered under CDA | disclosed to MGH

Funding Requirements

ProQR’s founding team has a vast experience in raising money for several biotech investments, to date well over [***]. In order to fund the Company into 2015, and through the completion of Phase I/II trials for PQR-01 for CF, ProQr will raise [***].

Initial funding for the first 18 months has been secured, and for subsequent steps a full financing round is ongoing. The initial VC funds have reacted positively to the proposition. Funding raised through straight equity financing will be leveraged by non-dilutive funding (e.g. Government grant and patient organizations).
