For clarity, this includes but is not limited to copies of all design requirements, specifications, technical drawings, standard operating procedures, component lists, and supplier lists relating to Manufacture of the Clearside Device and any other written materials maintained by Clearside or its Affiliates that are necessary for or used in the Manufacture of the Clearside Device (the “Escrow Materials”). The deposit of the Escrow Materials with the Escrow Agent will not affect Clearside’s right, title or interest in or to the Escrow Materials.

(b)The Escrow Agreement will require the Escrow Agent to release the Escrow Materials to REGENXBIO in the event an Insolvency Proceeding is instituted by or against Clearside or in the event of an Alternative Manufacturer Election if Clearside does not fulfill its obligations under Section 5.4.2(b)(x), (y) and (z) (any such event, “Escrow Release”). In the event of an Escrow Release, REGENXBIO will be entitled to full use of the Escrow Materials as necessary or useful to Manufacture Clearside Devices in furtherance of REGENXBIO’s exercise of the Commercial License. After Escrow Release, REGENXBIO will

have the right to use the Escrow Materials and will have the right to Manufacture Clearside Devices within the scope of the license under Section 3.1.

5.5.GMP. The Parties or their Affiliates will execute, as reasonably requested by REGENXBIO, agreements, such as a Quality Agreement, necessary or useful to ensure that all Clearside Devices and their intermediates and manufacturing facilities comply with GMP and all Applicable Laws. Clearside shall notify REGENXBIO in writing promptly after receiving Knowledge thereof, before any supplier or manufacturer implements any changes in Manufacturing processes for any Clearside Devices that would have regulatory relevance to any Covered Product. Such notice shall be given promptly after Clearside receiving Knowledge thereof. Clearside shall use commercially reasonable efforts to secure for REGENXBIO the opportunity to conduct full chemistry, manufacturing and controls due diligence and environmental, health and safety audits of Clearside Device suppliers and manufacturers prior to entering into any agreement and periodically thereafter, and Clearside shall use commercially reasonable efforts to obligate any such supplier or manufacturer to implement the changes and improvements stemming from such audits.

6.PAYMENTS TO CLEARSIDE. This Article 6 will automatically come into effect upon REGENXBIO’s exercise of the Option.

6.1.Option Exercise Fee. In partial consideration of the rights granted by Clearside to REGENXBIO hereunder and subject to the terms and conditions of this Agreement, REGENXBIO will pay to Clearside Two Million Dollars ($2,000,000), against which the technology access fee paid pursuant to Section 2 of the Technology Access Agreement is fully creditable, within thirty (30) days after REGENXBIO’s receipt of an invoice from Clearside for such amount that is issued by Clearside on or after the receipt of the Option Exercise Notice.

6.2.Development and Regulatory Milestone Payments.

6.2.1.Milestone Payments. In partial consideration of the rights granted by Clearside to REGENXBIO hereunder and subject to the terms and conditions of this Agreement, upon the occurrence of the corresponding event described in the table below, whether such milestone is achieved by REGENXBIO, an Affiliate or a Sublicensee, the corresponding payment will be due:


Development Milestones (USD)	Development Milestone Payment
Development Milestones (USD)	First Occurrence	Second Occurrence	Third Occurrence
[***]	[***]	[***]	[***]
[***]	[***]	[***]	[***]

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

Notwithstanding the foregoing:

(a)only one (1) occurrence of a given Development Milestone will be payable for the same Covered Product for a single Indication;

(b)only two (2) occurrences of a given Development Milestone will be payable for Covered Products including the same AAV Active Substance; and

(c)Development Milestones will not be payable for any Covered Product for the treatment of Xxxxxx Disease.

Examples of the calculation of Development Milestones payable under this Section 6.2.1 are attached hereto as Exhibit D.

6.2.2.Notice; Payments. Within [***] after the occurrence of a Development Milestone, REGENXBIO will send Clearside a written notice identifying the Covered Product that achieved the Development Milestone and the Development Milestone Payment Amount set forth above with respect to such Development Milestone. Thereafter, Clearside will promptly invoice REGENXBIO for the achievement of the Development Milestone, identifying in its invoice the Covered Product, the Development Milestone achieved and the amount of the Development Milestone Payment, and such Development Milestone Payment will be due within [***] after REGENXBIO’s receipt of such invoice.

6.2.3.Milestones Payable Only Once. For clarity, each Development Milestone Payment will be payable only once regardless of the number of Covered Products to achieve the Development Milestone, and the maximum total Development Milestone Payments payable for all Covered Products under this Agreement will not exceed Thirty-Four Million Dollars ($34,000,000).

6.3.Commercial Milestones. In partial consideration of the rights granted by Clearside to REGENXBIO hereunder and subject to the terms and conditions of this Agreement, REGENXBIO will make the following payments (each such amount, a “Commercial Milestone Payment”), following the first occurrence of each event described in the table below (each, a “Commercial Milestone”) for Covered Products, whether such milestone is achieved by REGENXBIO, an Affiliate and/or a Sublicensee:


Commercial Milestone	Commercial Milestone Payment
For the first Calendar Year during the Term in which the aggregate of all Net Sales of Covered Products for such Calendar Year exceeds [***]	$[***]

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

For the first Calendar Year during the Term in which the aggregate of all Net Sales of Covered Products for such Calendar Year exceeds [***]	[***]
Total	[***]

Within [***] after the occurrence of a Commercial Milestone, REGENXBIO will send Clearside a written notice identifying the Commercial Milestone and the Commercial Milestone Payment Amount set forth above with respect to such Commercial Milestone. Thereafter, Clearside will promptly invoice REGENXBIO for the achievement of the Commercial Milestone and such Commercial Milestone Payment will be due within [***] after REGENXBIO’s receipt of such invoice.

Clearside acknowledges and agrees that the sales levels set forth in this Section 6.3 will not be construed as representing an estimate or projection of anticipated sales of Covered Products in the Territory or implying any level of diligence beyond that required pursuant to Section 4.1, and that the sales levels set forth above are merely intended to define REGENXBIO’s milestone obligations in the event such sales levels are achieved.

6.4.Royalties.

6.4.1.Royalty Rates. As further consideration for the rights granted to REGENXBIO hereunder and subject to the terms and conditions of this Agreement, during the Royalty Term, REGENXBIO will pay to Clearside a royalty in the amount of [***] of Net Sales of Covered Products by REGENXBIO, its Affiliates and Sublicensees, subject to the royalty reductions set forth below. REGENXBIO will have no obligation to pay any royalty with respect to Net Sales of Covered Product in any country after the Royalty Term for such Covered Product

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

in such country has expired. Following the expiration of the Royalty Term for Covered Product in a country, the grants in Section 3.1 will become fully-paid, royalty-free, perpetual and irrevocable for such Covered Product in such country, and no further royalties will be payable.

6.4.2.Royalty Reductions.

(a)Anti-Stacking. If, in connection with the Manufacture, use or Commercialization of Covered Product, REGENXBIO is obligated to pay royalties to Clearside and any Third Parties solely in order to Exploit the Clearside Device (including administration of Covered Product using the Clearside Device) that, in the aggregate, exceed [***] of Net Sales for Covered Product, then the royalty owed to Clearside for that Covered Product will be reduced by an amount calculated in accordance with the formula set forth in Exhibit E.

Notwithstanding the foregoing, Section 6.4.2(a) will not reduce any single royalty payment payable to Clearside by more than [***] of what it would otherwise be payable by operation of Section 6.4.1. Credits not exhausted in any Calendar Quarter may be carried into future Calendar Quarters, subject to the foregoing sentence.

(b)No Valid Claim. If, during the Royalty Term, no Valid Claim of the Clearside Patent Rights exists that Covers the Clearside Device in the Territory, then: (i) the royalty that would otherwise be payable will be reduced to [***] for the remainder of the Royalty Term, if any; and (ii) if there is another microneedle device that is Commercialized by a Third Party in such country that would have infringed a claim of the Clearside Patents if such claim was a Valid Claim, the royalty will be further reduced to [***].

6.5.Royalty Payments and Reports. REGENXBIO will calculate all amounts payable to Clearside pursuant to Section 6.3 at the end of each Calendar Quarter, which amounts will be converted to Dollars, in accordance with Section 6.6. REGENXBIO will pay to Clearside the royalty amounts due with respect to a given Calendar Quarter within [***] after the end of such Calendar Quarter. Each payment of royalties due to Clearside will be accompanied by a statement of the amount of gross sales, Net Sales, and number of units of Covered Product(s) in each country in the Territory during the applicable Calendar Quarter (including such amounts expressed in local currency and as converted to Dollars) and a calculation of the amount of royalty payment due on such Net Sales for such Calendar Quarter, which calculation shall include the itemized deductions for Covered Products for each country included in the calculation of Net Sales. REGENXBIO will also include in such reports any additional information reasonably requested by Clearside to calculate Net Sales attributable to its Affiliates and Sublicensees.

6.6.Currency; Payment Instructions; Late Payments. All amounts payable and calculations hereunder will be in Dollars, and all payments due under this Agreement will be made by wire transfer in immediately available funds to an account designated by Clearside in advance of such payment, or by other mutually acceptable means. For the purpose of calculating any sums due under, or otherwise reimbursable pursuant to, this Agreement (including the calculation of Net Sales expressed in currencies other than Dollars), a Party will convert any amount expressed in a foreign currency into Dollar equivalents using its, its Affiliate’s or Sublicensee’s standard conversion methodology consistent with GAAP. If any payment due to either Party under this

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

Agreement is not paid when due, then such paying Party will pay interest thereon (before and after any judgment) at an annual rate (but with interest accruing on a daily basis) of [***] basis points above the U.S. effective federal funds rate, as adjusted each Business Day and published by the Federal Reserve Bank of New York through its website (xxxxx://xxxx.xxxxxxxxxx.xxx/xxxxxxx/xxxxxxxxx/xxx%00xxxxx) (or in the event that the U.S. effective federal funds rate is no longer an applicable reference rate, such reasonably equivalent alternative as may be selected by mutual agreement exercising reasonable discretion), such interest to run from the date on which payment of such sum became due until payment thereof in full together with such interest. Notwithstanding the previous sentence, the total payable interest rate will never be less than [***] basis points.

6.7.Taxes.

6.7.1.General. The milestones, royalties and other amounts payable by REGENXBIO to Clearside pursuant to this Agreement (each, a “Payment”) will be paid free and clear of any and all taxes, except for any withholding taxes required by Applicable Law. Except as provided in this Section 6.7, Clearside will be solely responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be deducted from Payments and remitted by REGENXBIO) levied on account of, or measured in whole or in part by reference to, any Payments it receives. REGENXBIO will deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Clearside is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to REGENXBIO or the appropriate governmental authority (with the assistance of REGENXBIO to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve REGENXBIO of its obligation to withhold such tax and REGENXBIO will apply the reduced rate of withholding or dispense with withholding, as the case may be; provided that REGENXBIO has received evidence, in a form reasonably satisfactory to REGENXBIO, of Clearside’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least [***] prior to the time that the Payments are due. If, in accordance with the foregoing, REGENXBIO withholds any amount, it will pay to Clearside the balance when due, make timely payment to the proper taxing authority of the withheld amount and send to Clearside proof of such payment within [***] following such payment.

6.8.Financial Records. REGENXBIO will, and will cause its Affiliates and its and their Sublicensees to, keep complete and accurate financial books and records pertaining to the Development and Commercialization of Covered Product hereunder to the extent required to calculate and verify all amounts payable hereunder. REGENXBIO will, and will cause its Affiliates and its and their Sublicensees to, retain such books and records until [***] after the end of the period to which such books and records pertain.

6.9.Audit. Upon Clearside’s or EGT Licensors’ request, REGENXBIO will, and will cause its Affiliates and its and their Sublicensees to, permit an independent, nationally recognized accounting firm designated by Clearside or EGT Licensor and reasonably acceptable to REGENXBIO, at reasonable times and upon reasonable notice, to audit the books and records

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

maintained pursuant to Section 6.8 to ensure the accuracy of all reports and payments under this Agreement. Such examinations may not be conducted more than [***] in any [***] period and are limited to the preceding [***] period. The cost of this audit will be borne by Clearside, unless the audit reveals a variance of more than [***] from the reported amounts, in which case REGENXBIO will reimburse Clearside for the accounting firm’s fees in performing the audit. If such audit concludes that (a) additional amounts were owed by REGENXBIO, REGENXBIO will pay the additional amounts or (b) excess payments were made by REGENXBIO, Clearside will reimburse or credit such excess payments, in either case ((a) or (b)), within [***] after the date on which such audit is completed.

6.10.Confidentiality. The Receiving Party will treat all information subject to review under this Article 6 in accordance with the confidentiality provisions of Article 8 and the Parties will cause the Auditor to enter into a reasonably acceptable confidentiality agreement with the audited Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement.

7.PATENT MATTERS; OWNERSHIP OF INTELLECTUAL PROPERTY. This Article 7 will automatically come into effect upon REGENXBIO’s exercise of the Option.

7.1.Filing, Prosecution and Maintenance of Patent Rights.

7.1.1.EGT Patent Rights. The EGT Licensor will be responsible for filing for, prosecution and maintenance of the EGT Patent Rights in accordance with the terms of the Emory/Georgia Tech Agreement. Clearside will provide REGENXBIO with all information that is provided to Clearside by the EGT Licensor with respect to the EGT Patent Rights related to use of the Clearside Device for delivery of an AAV Active Substance in the Field in accordance with Article 7 of the Emory/Georgia Tech Agreement promptly and with sufficient time for REGENXBIO to review and comment thereon. If Clearside and EGT Licensor elect not to continue to seek or maintain any EGT Patent Rights related to use of the Clearside Device for delivery of an AAV Active Substance in the Field, then: (a) to the extent REGENXBIO is the sole exclusive sublicensee of such EGT Patent Rights (including, for clarity, to the extent the subject matter of the EGT Patent Rights relates to the use of the Clearside Device for delivery of an AAV Active Substance in the Field), Clearside will provide REGENXBIO with timely notice and will provide REGENXBIO with a reasonable opportunity to assume responsibility for the continued prosecution and maintenance of such EGT Patent Rights, or (b) to the extent REGENXBIO is not the sole exclusive sublicensee of such EGT Patent Rights, Clearside will provide REGENXBIO with timely notice and REGENXBIO and the other exclusive licensees will negotiate in good faith regarding the assumption of responsibility for the continued prosecution and maintenance of such EGT Patent Rights.

7.1.2.Other Clearside Patent Rights. For any Clearside Patent Rights not covered by Section 7.1.1, this Section 7.1.2 will apply. Clearside has the first right, at its discretion and using counsel it selects, to prepare, file, prosecute and maintain all Clearside Patent Rights in Clearside’s name in the Territory. Clearside will: (i) instruct such patent counsel to provide REGENXBIO with copies of all filings and formal correspondences relating to the Clearside

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

Patent Rights related to use of the Clearside Device for delivery of an AAV Active Substance in the Field to and from the United States Patent and Trademark Office and any other patent office (including copies of each patent application, office action, response to office action, request for terminal disclaimer, and request for reissue or reexamination of any patent or patent application) and (ii) keep REGENXBIO advised of the status of actual and prospective patent filings related to use of the Clearside Device for delivery of an AAV Active Substance in the Field. Clearside will give REGENXBIO the opportunity to provide and will reasonably consider comments on the preparation, filing, prosecution and maintenance of the Clearside Patent Rights related to use of the Clearside Device for delivery of an AAV Active Substance in the Field. Each Party will treat any consultation regarding the preparation, filing, prosecution and maintenance of the Clearside Patent Rights, along with any information disclosed by each Party in connection therewith (including any information concerning patent expenses), as Confidential Information. If Clearside elects not to continue to seek or maintain any Clearside Patent Rights related to use of the Clearside Device for delivery of an AAV Active Substance in the Field, then: (a) to the extent REGENXBIO is the sole exclusive licensee of such Clearside Patent Rights (including, for clarity, to the extent the subject matter of the Clearside Patent Rights relates to the use of the Clearside Device for delivery of an AAV Active Substance in the Field), Clearside will provide REGENXBIO with timely notice and will provide REGENXBIO with a reasonable opportunity to assume responsibility for the continued prosecution and maintenance of such Clearside Patent Rights, or (b) to the extent REGENXBIO is not the sole exclusive licensee of such Clearside Patent Rights, Clearside will provide REGENXBIO with timely notice and REGENXBIO and the other exclusive licensees will negotiate in good faith regarding the assumption of responsibility for the continued prosecution and maintenance of such Clearside Patent Rights.

7.1.3.Information Sharing. Clearside (if Clearside or EGT Licensor is the prosecuting party under Section 7.1.1 or Section 7.1.2) or REGENXBIO (if REGENXBIO or an Affiliate or Sublicensee is the prosecuting party under Section 7.1.1 or Section 7.1.2) (as applicable, the “Prosecuting Party”), will: (i) instruct such patent counsel to provide the other Party (the “Non-Prosecuting Party”) with copies of all filings and formal correspondences relating to such Clearside Patent Rights to and from the United States Patent and Trademark Office and any other patent office (including copies of each patent application, office action, response to office action, request for terminal disclaimer, and request for reissue or reexamination of any patent or patent application) and (ii) keep the Non-Prosecuting Party advised of the status of actual and prospective patent filings related to use of the Clearside Device for delivery of an AAV Active Substance in the Field. The Prosecuting Party will give the Non-Prosecuting Party the opportunity to provide and will reasonably consider comments on the preparation, filing, prosecution and maintenance of such Clearside Patent Rights. Each Party will treat any consultation regarding the preparation, filing, prosecution and maintenance of the Clearside Patent Rights, along with any information disclosed by each Party in connection therewith (including any information concerning patent expenses), as the other Party’s Confidential Information.

7.2.Enforcement of Rights.

7.2.1.Notification. In the event that either Party becomes aware of any actual or threatened infringement of any Clearside Patent Right in the Territory by a Third Party, such Party

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

will promptly notify the other Party in writing and will provide any information available to such Party relating to such infringement.

7.2.2.Infringement of Clearside Patents. Clearside will generally have the first right but not the obligation, to enforce the Clearside Patent Rights, including in the Field, in the Territory. Notwithstanding the foregoing, REGENXBIO will have the first right but not the obligation to enforce the Clearside Patent Rights to the extent any enforcement action solely alleges infringement of a Clearside Patent Right by the use of the Clearside Device for delivery of an AAV Active Substance in the Field in the Territory. The Party with such first right will notify the other Party of its election within [***] after notification of such Clearside Patent Right infringement pursuant to Section 7.2.1 above. In the case where Clearside has the first right to enforce the Clearside Patent Rights and elects not to pursue such action: (a) if REGENXBIO is the sole exclusive licensee with respect to such Clearside Patent Rights, REGENXBIO will have the right, but not the obligation, to commence a suit or take action relating to such infringement, subject to the terms of the Emory/Georgia Tech Agreement; or (b) if REGENXBIO is not the sole exclusive licensee with respect to such Clearside Patent Rights, REGENXBIO and the other sole exclusive licensees shall negotiate in good faith regarding the commencement of any suit or the taking of any action relating to such infringement, subject to the terms of the Emory/Georgia Tech Agreement. The Party not bringing an action with respect to Clearside Patent Right will be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party will at all times cooperate fully with the enforcing Party. Additionally, the Party not bringing an action under the Clearside Patent Rights may have an opportunity to participate in such action, at its sole cost and expense, to the extent that the Parties may mutually agree at the time the enforcing Party elects to bring such action hereunder and, whether or not the Party not bringing the action elects to participate, the Party bringing the action will provide regular updates on the status of the action to the Party not bringing the action. If the enforcing Party recovers monetary damages from any Third Party in a suit or action for infringement of Clearside Patent Rights, such recovery will be allocated: (x) first to the repayment of out-of-pocket costs and expenses of the Party(ies) with respect to the action (on a pro rata basis); (y) second, if such suit is related to EGT Patent Rights, to the payment of any amounts required to be paid to the EGT Licensor under the Emory/Georgia Tech Agreement; and (z) if Clearside (i) is not the enforcing Party, any remaining damages will be treated as Net Sales of Covered Product under this Agreement or, (ii) is the enforcing Party, any remaining damages will be retained by Clearside; provided, however, that, if Clearside is the enforcing party and such enforcement is not related to use of the Clearside Device for delivery of an AAV Active Substance in the Field, such remaining damages shall be retained by Clearside. In any action, suit or proceeding instituted under this Section 7.2, the Parties will cooperate with and assist each other in all reasonable respects. Upon the reasonable request of the Party initiating such action, suit or proceeding, the other Party will join such action, suit or proceeding if necessary to establish standing in such action, suit or proceeding, and may be represented using counsel of its own choice, at such initiating Party’s expense, or assign the right to enforce the patents to the Party initiating such action. Neither Party will have the right to settle any patent infringement litigation under this Section 7.2 in a manner that admits the invalidity or unenforceability of the other Party’s Patent Rights or imposes on the other Party restrictions or obligations, without the written consent of such other Party (which will not be unreasonably withheld).

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

7.3.Privileged Information. Neither Party will be required to provide legally privileged information relating to any infringement or other matter contemplated under this Article 7 until procedures and documentation reasonably acceptable to such Party are in place to protect such privileged information.

7.4.Patent Term Extension and Supplementary Protection Certificate. The Parties will cooperate regarding patent term extensions for any Patent Rights covering Joint Inventions and for Clearside Patent Rights covering a Covered Product in the Field and Territory, including the United States with respect to extensions pursuant to 35 U.S.C. §156 et. seq. and in other jurisdictions pursuant to supplementary protection certificates, and in all jurisdictions with respect to any other extensions that are now or become available in the future, wherever applicable. In the event that the Parties determine to apply for any patent term extension or supplementary protection certificate for any Patent Rights covering Joint Inventions and Clearside Patent Rights covering a Covered Product in the Field and Territory, each Party shall provide prompt and reasonable assistance, including taking such action as patent holder or co-owner as is required under any Applicable Law to obtain such extension or supplementary protection certificate.

7.5.Ownership of Intellectual Property.

7.5.1.Background IP. Subject to the licenses granted by Clearside pursuant to this Agreement, each Party owns and will continue to own all Intellectual Property: (a) owned or Controlled by such Party as of the Effective Date, or (b) except as set forth in Section 7.5.2, that are Invented solely by Representatives of such Party or its Affiliates.

7.5.2.Inventions. Any such Intellectual Property Invented in the course of performing Development assistance pursuant to Section 4.2.4 shall be (a) jointly owned by Clearside and REGENXBIO to the extent related to the combined use of Clearside Device and an AAV Active Substance (“Joint Inventions”); (b) owned solely by REGENXBIO to the extent related to an AAV Active Substance without the use of Clearside Device (“REGENXBIO Inventions”); (c) owned solely by Clearside to the extent related to the use of the Clearside Device alone or in combination with any substance other than an AAV Active Substance for use in the Field (“Clearside Inventions”). With respect to Exploitation of Joint Inventions outside the scope of the Commercial License, the Parties shall (i) first, negotiate in good faith for one or both Parties to obtain ownership or an exclusive license to the other Party’s interest in all or a portion of such Joint Invention and (ii) subject to any transaction contemplated by the foregoing clause (i), neither Party shall be permitted to sublicense such Joint Invention without the other Party’s prior written consent, not to be unreasonably withheld. Each Party agrees to execute any and all further instruments, forms of assignment or other documents, and take such further actions, as the other may reasonably request, in order to give effect to these ownership provisions in connection with REGENXBIO Inventions and Clearside Inventions.

8.CONFIDENTIALITY

8.1.Protection of Confidential Information. Except to the extent expressly authorized by this Agreement, the Parties agree that each Party (the “Receiving Party”) receiving any Confidential Information of the other Party (the “Disclosing Party”) will not disclose or

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

disseminate Confidential Information of the Disclosing Party to any Third Party unless expressly permitted hereunder, and will not use such Confidential Information for any purpose other than in performing the Receiving Party’s obligations or exercising the Receiving Party’s rights hereunder. In addition, the Receiving Party will take reasonable steps to protect the Confidential Information of the Disclosing Party from unauthorized use or disclosure, which steps will be no less than those the Receiving Party takes to protect its own confidential and/or proprietary material of a similar nature. The foregoing obligations will apply equally to all copies, extracts and summaries of the Disclosing Party’s Confidential Information. The obligations in this Section 8.1 will apply for a period of [***] after disclosure of the Confidential Information.

8.2.Certain Permitted Disclosures.

8.2.1.Disclosure of Confidential Information.

(a)Disclosure to Representatives. Notwithstanding the foregoing and subject to Section 8.2.1(b), the Receiving Party may disclose Confidential Information of the Disclosing Party to [***] (collectively, “Representatives”) who have a need to know such Confidential Information in connection with the performance of the Receiving Party’s obligations or the exercise of the Receiving Party’s rights under this Agreement; provided that such Representative is bound by a confidentiality agreement with such Receiving Party that contains terms substantially similar to this Article 8.

(b)Disclosures under Applicable Law. Notwithstanding the foregoing, each Party may disclose Confidential Information of the other Party to a Third Party to the extent such disclosure is reasonably necessary to prepare, file or prosecute Patent Rights (consistent with all other limitations set forth in this Agreement), prepare submissions to Regulatory Authorities, prosecute or defend litigation, comply with Applicable Law or submit information to Governmental Authorities provided that such Third Party, if not a governmental entity, enters into a confidentiality agreement with such Party that contains terms no less restrictive than this Article 8; provided, however, that if a Party intends to make any such disclosure of the Disclosing Party’s Confidential Information, to the extent it may legally do so it will give reasonable advance notice to the Disclosing Party of such disclosure to permit the Disclosing Party to use its reasonable endeavors to secure confidential treatment of such Confidential Information prior to disclosure (whether through protective orders or otherwise).

8.2.2.Disclosure of Agreement Terms to Certain Third Parties. The Parties may disclose only the terms or conditions of this Agreement (but not any Confidential Information of the other Party) on a need-to-know basis (a) to its legal and financial advisors to the extent such disclosure is reasonably necessary in connection with such Party’s activities as expressly permitted by this Agreement, and (b) to a Third Party in connection with: (i) an actual or potential equity investment in or by, or underwriting by, such Third Party, (ii) an actual or potential merger, consolidation or similar transaction involving such Third Party, (iii) the sale or potential sale of all or substantially all of the assets of the Party or substantially all of the assets related to this Agreement to such Third Party or (iv) a potential or actual sublicensee hereunder and/or collaborator in relation to any Commercial License Terms; provided that such Party will make

such disclosure only under appropriate conditions of confidentiality by the Third Party of confidentiality and non-use at least equivalent in scope to those set forth in this Article 8. Notwithstanding the foregoing, Clearside may provide an unredacted copy of this Agreement to the EGT Licensor for the purpose of complying with the Emory/Georgia Tech Agreement.

8.3.Securities Law Filings and Other Disclosures. Notwithstanding any provision of this Agreement to the contrary, either Party may disclose the terms of this Agreement to the extent required, in the advice of such Party’s legal counsel, to comply with Applicable Law, including the rules and regulations promulgated by the SEC, AMF or any equivalent governmental agency in any country, or the rules of any stock exchange in which a Party is listed. Notwithstanding the foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 8.3, the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure, with the filing Party giving due consideration to the other Party’s input. Further, if a Party discloses this Agreement or any of the terms hereof in accordance with this Section 8.3, such Party will, at its own expense, maintain as confidential the portions of this Agreement and such other terms, as may be reasonably requested by the other Party provided, however, that the Parties agree that the financial terms in this Agreement must be redacted from any public disclosure except to the extent they have been previously disclosed in a press release or other publication pursuant to the Parties’ mutual agreement.

8.4.Public Announcements. The Parties will agree upon the content of one (1) or more press releases, the release of which the Parties will coordinate after the Effective Date. Except as may be expressly permitted under Section 8.3, neither Party will make any other public announcement regarding this Agreement without the prior written approval of the other Party. Notwithstanding the foregoing, REGENXBIO and its Affiliates and its and their Sublicensees will have the right to publicly disclose research, development and commercial information (including with respect to regulatory matters) regarding Covered Product provided such disclosure: (a) does not contain non-public or Confidential Information related to any Clearside Device; and (b) does not contain any claims relating to the use of the Clearside Device in a manner that is contrary to, or would have an adverse effect on, any Regulatory Approval held by Clearside related to the Clearside Device.

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

(b)in the Territory or on a country-by-country basis, for any or no reason, upon [***] prior written notice to Clearside.

10.2.5.Consequences of Termination.

(a)Termination in the Entire Territory. In the event of a termination of this Agreement for the entire Territory with respect to Covered Product for any reason, all rights and licenses granted by either Party with respect to such Covered Product hereunder will immediately terminate.

(ii)Notwithstanding the termination of REGENXBIO’s licenses and other rights under this Agreement, solely upon termination of this Agreement by REGENXBIO because of a Clearside material breach or Clearside Insolvency Proceeding, REGENXBIO will have the nonexclusive right for [***] after the effective date of such termination to sell or otherwise dispose of all Clearside Devices for use with Covered Product then in its inventory and any in-progress inventory as though this Agreement had not terminated, and such sale or disposition will not constitute infringement of Clearside’s or its Affiliates’ Patent Rights or other intellectual property or other proprietary rights. For the avoidance of doubt, REGENXBIO will continue to make payments thereon as provided in Section 6.3 and 6.4 (as if this Agreement had not terminated).

(c)Emory/Georgia Tech Agreement. In addition, if the Emory/Georgia Tech Agreement terminates for any reason, REGENXBIO shall, unless this

For the avoidance of doubt, any other Section that explicitly states it survives expiration or termination of this Agreement will so survive.

10.4.3.If this Agreement is terminated with respect to Covered Product for a Terminated Territory but not in its entirety, then following such termination the foregoing provisions of this Agreement will remain in effect with respect to the Terminated Territory (to the extent they would survive and apply in the event the Agreement expires or is terminated in its entirety or as otherwise necessary for any of REGENXBIO and its Affiliates and its and their Sublicensees to exercise their rights in the Territory) and all provisions not surviving in accordance with the foregoing will terminate upon termination of this Agreement with respect to such Covered Product for the Terminated Territory and be of no further force and effect (and for the avoidance of doubt all provisions of this Agreement will remain in effect for such Covered Product with respect to all countries in the Territory other than the Terminated Territory).

Any dispute, controversy or claim that may arise relating to the terms of this Agreement, the interpretation thereof or the compliance of the Parties therewith will be referred to the CEO of Clearside and the CEO of REGENXBIO (or their respective designee who has the authority to make decisions on behalf of such Party) who will negotiate in good faith to resolve the dispute. If any dispute is not resolved by these individuals (or their designees) within [***] after such dispute is referred to them, or such longer period as they may mutually agree, either Party may resort to the federal courts of the State of Delaware for resolution of the dispute. Notwithstanding anything to the contrary in this Agreement, if either Party in its sole judgment believes that any such dispute could cause it irreparable harm, including disputes or matters related to intellectual property, such Party (i) will be entitled to seek equitable relief in order to avoid such irreparable harm and (ii) will not be required to follow the procedures set forth in this Section 12.11. The provisions of this Section 12.11 will survive the termination or expiration of this Agreement.

12.12.Entire Agreement. This Agreement, including any Exhibits hereto and thereto, constitute and contain the complete, final and exclusive understanding and agreement of the Parties and cancel and supersede any and all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof and thereof, including the Confidentiality Agreement which is hereby terminated effective as of the Effective Date. Notwithstanding the foregoing, unless and until the Option is exercised in accordance with Section 2.2 of this Agreement or the Technology Access Agreement is terminated in accordance with its terms, the Technology Access Agreement will remain in full force and effect.

12.13.Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing herein contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

12.14.Cumulative Rights. The rights, powers and remedies hereunder will be in addition to, and not in limitation of, all rights, powers and remedies provided at law or in equity, or under any other agreement between the Parties. All of such rights, powers and remedies will be cumulative, and may be exercised successively or cumulatively.

Certain information has been excluded from this agreement (indicated by “[***]”) because such information (i) is not material and (ii) would be competitively harmful if publicly disclosed.

12.15.Counterparts. This Agreement may be executed in two (2) counterparts, each of which will be an original and both of which will constitute together the same document. Counterparts may be signed and delivered by facsimile or PDF file, each of which will be binding when received by the applicable Party.

12.16.Interpretation. Unless the context of this Agreement otherwise requires: (a) words of one gender include the other gender; (b) words using the singular or plural number also include the plural or singular number, respectively; (c) the terms “hereof,” “herein,” “hereby,” and other similar words refer to this entire Agreement; (d) the words “include”, “includes”, and “including” when used in this Agreement will be deemed to be followed by the words “without limitation”, unless otherwise specified; (e) the terms “Article” and “Section” refer to the specified Article and Section of this Agreement; and (f) the word “withheld” in the phrases “withheld unreasonably” or “unreasonably withheld” and other forms of such words, will be deemed to be followed by the words “conditioned or delayed,” and (g) the use of “or” is not intended to be exclusive unless expressly indicated otherwise.

12.17.No Third Party Rights or Obligations. Notwithstanding a Clearside Indemnified Party, other than the EGT Licensors, or a REGENXBIO Indemnified Party’s right to indemnification under Section 11.2 and 11.3 (which, for clarity, must be exercised through a Party and may not be exercised directly by such Persons), no provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligation in any Person not a Party to this Agreement; provided, however, that the EGT Licensors may directly enforce their rights hereunder. However, either Party may decide, in its sole discretion, to use one or more of its Affiliates to perform its obligations and duties hereunder, provided that such deciding Party will remain liable hereunder for the performance by any such Affiliates of any such obligations.
