rights of Oculis under the terms of this Agreement. Oculis shall have no right to exploit and/or practice, and shall not exploit and/or practice, any such Oculis Improvements outside the Field in the Territory insofar as such actions would otherwise
infringe or use Licensed IP. 
 (f)    Alcon hereby covenants that it shall not enforce, or permit or encourage the
enforcement of, against Oculis or any of its Affiliates, or direct or indirect customers, sublicensees, successors or assignees, any Patents owned or controlled by Alcon or its Affiliates solely in connection with the Development, Manufacture or
Commercialization of a Licensed Product in the Field in the Territory. Alcon shall ensure that the covenant above is binding upon its Affiliates and sublicensees, and in the event Oculis transfers any rights under the Licensed IP to a Third Party,
Alcon shall ensure that such covenant not to sue is binding upon such Third Party. 
 5.2    No Diminution of
Rights. Oculis shall not do or omit to do anything that would substantially diminish or impair the rights of Alcon and/or its Affiliates in the Licensed IP and/or Manufacturing Platform Technology, provided however, that the foregoing shall not
restrict Oculis’ discretion as to the Development, use, Manufacture and Commercialization of the Compound and/or the Licensed Products so long as Oculis complies with its obligation to use its Diligent Efforts in connection with such activities
in accordance with Section 4. If any Party becomes aware of any claim or challenge to the validity of the Licensed IP and/or Manufacturing Platform Technology, it shall promptly inform the other Party. 

5.3     Prosecution and Defense of Licensed Patents.

 (a)    Oculis Inventions and Oculis Improvements. As of the Effective Date, Oculis shall be solely responsible
for the filing, prosecution, defense (including, for example, in inter partes reviews, post-grant reviews, oppositions, and derivation proceedings) and maintenance of any Patents claiming Oculis Inventions, and Oculis Improvements. Alcon will
provide such information as is required by Oculis in connection with such activities. Oculis shall be responsible for all costs and expenses incurred by it relating to such filing, maintenance, defense, and prosecution, including attorneys’
fees incurred by Oculis in connection with the Oculis Inventions and Oculis Improvements. Alcon shall reimburse Oculis for [***] of all reasonable, well documented
out-of-pocket costs and expenses incurred by Oculis in connection with the prosecution and maintenance of Patents covering Oculis Improvements, which reimbursement shall
be made within [***] after receipt of an invoice therefor. If Oculis elects not to prosecute and maintain or to discontinue prosecuting and maintaining any of such Patents (the “Discontinued Patents”), it shall notify Alcon in
writing within [***] of such decision and Alcon may elect at its sole discretion to prosecute and maintain or to continue to prosecute and maintain the Discontinued Patents at its sole expense, in which case the Discontinued Patents shall become
part of the Licensed IP. Oculis shall regularly consult with Alcon and shall keep Alcon reasonably informed of all aspects of such filing, prosecution, defense, and maintenance of such Patents covering Oculis Improvements, including providing such
information and documentation as Alcon may reasonably require from time to time, and Oculis shall in good faith consider and not unreasonably reject Alcon’s comments and/or recommendations regarding the same.

 (b)    Licensed Platform Patents. Alcon shall be solely
responsible for the filing, prosecution, defense (including, for example, in inter partes reviews, post-grant reviews, oppositions, and derivation proceedings) and maintenance of the Licensed Platform Patents . For Licensed Platform Patents, Alcon
shall be responsible for all costs and expenses incurred in relation to such filing, maintenance, defense, and prosecution, including attorneys’ fees and internal costs incurred in connection therewith. Alcon shall regularly consult with Oculis
and shall keep Oculis reasonably informed of all aspects of such filing, prosecution, defense, and maintenance of the Licensed Platform Patents to the extent pending claims are related to the Compound, including providing such information and
documentation as Oculis may reasonably require from time to time, and Alcon shall in good faith consider and not unreasonably reject requests, comments and/or recommendations regarding the same, including but not limited to requests not to prosecute
and maintain or to discontinue prosecuting and maintaining any Licensed Platform Patents with claims that solely relate to the Compound. The foregoing notwithstanding, if any Licensed Platform Patents are granted with claims that solely relate to
the Compound and are not subject to the Delenex License, Oculis shall reimburse Alcon for all costs and expenses in relation to maintenance of such Patents, including attorney’s fees and out of pocket costs. For the avoidance of doubt, the
forgoing only relates to maintenance, and not enforcement or defense. Oculis shall timely provide Alcon with instructions regarding payment of issue and grant fees and European validation decisions for Licensed Platform Patents having allowed or
granted claims solely related to the Compound. 
 (c)    Licensed Compound Patents. Oculis shall be solely
responsible for the filing, prosecution, defense (including, for example, in inter partes review, post-grant reviews, oppositions, and derivation proceedings), and maintenance of the Licensed Compound Patent identified as Alcon Docket Number [***].
Oculis shall regularly consult with Alcon and shall keep Alcon reasonably informed of all aspects of such filing, prosecution, defense, and maintenance of the Licensed Compound Patents, including providing such information and documentation as Alcon
may reasonably require from time to time, and Oculis shall in good faith consider and not unreasonably reject comments and/or recommendations regarding the same. Oculis hereby agrees not to pursue any claims in the [***] patent family that do not
explicitly cover the Compound. Alcon shall be solely responsible for the filing, prosecution, defense (including, for example, in inter partes review, post-grant reviews, oppositions, and derivation proceedings), and maintenance of the Licensed
Compound Patent identified as Alcon Docket Number [***]. Alcon shall keep CellMedica reasonably informed of all aspects of such filing, prosecution, defense, and maintenance of the [***] patent family, and Alcon shall in good faith consider and not
unreasonably reject comments and/or recommendations regarding the same to the extent required under the Delenex License. Oculis shall reimburse for [***] in connection with the prosecution and maintenance of the [***] patent family incurred after
the Effective Date, which reimbursement shall be made by Oculis within [***] after receipt of an invoice therefor from Alcon. For the avoidance of doubt, the foregoing only relates to prosecution and maintenance, and not

enforcement or defense. Oculis shall timely provide Alcon with instructions regarding payment of issue and grant fees and European validation decisions for [***] patent family having allowed or
granted claims to the extent Alcon has obligations to CellMedica with respect thereto under the Delenex License. 

(d)    If Alcon elects not to prosecute and maintain or to discontinue prosecuting and maintaining any Licensed Patents
(“Alcon Discontinued Patents”), it shall notify Oculis in writing within [***] of such decision and Oculis may elect at its sole discretion to prosecute and maintain or to continue to prosecute and maintain the Alcon Discontinued
Patents at its sole expense. If Oculis does not exercise its rights to prosecute and maintain or to continue to prosecute and maintain the Alcon Discontinued Patents at its own expense, then Oculis acknowledges that Alcon may enable CellMedica to
exercise rights pursuant to Section 4.2(d) of the Delenex License. 
 5.4    Patent Extensions Based on
Marketing Authorizations. Oculis shall have the right to file and maintain any regulatory patent extensions on any Licensed Patent (such as supplementary protection certificates or patent term extensions) to the extent such extension is based on
a marketing authorization granted to Oculis for use of the Compound in the Field, whereby Oculis shall confer with Alcon to determine which, if any, of the Licensed Patents it shall apply for an extension. 

5.5    Infringement. Each Party shall promptly notify the other Party of any actual, suspected or threatened
infringement, violation or misappropriation within the Territory of the Licensed Patents (“Infringement”) that comes to its attention. 

5.6    Right to Bring Action. Except as set forth in Section 5.7, Oculis shall have the sole right to
send notices and bring and conduct actions in relation to any Infringement of the Licensed Compound Patents in the Territory to the extent such Infringement is solely within the Field in the Territory. Alcon will reasonably cooperate with Oculis in
taking all reasonable steps requested by Oculis in connection with any Infringement action, including joining in Legal Proceedings. Oculis shall bear the costs of any such Legal Proceedings, and Oculis shall be entitled to any damages, account of
profits and/or awards of costs recovered. 
 5.7    Exception. In the event that Oculis does not take reasonable
steps to prevent any individual Infringement of Licensed Compound Patents within [***] or within such time as may be required by any applicable Law to prevent the loss of rights, whichever is later, of becoming aware or receiving written notice
thereof, subject to the Delenex License, Alcon shall hereafter have the sole right (but shall not be under any obligation in this regard) to send notices and bring and conduct actions in relation to such Infringement. Oculis will cooperate fully
with Alcon in taking all reasonable steps requested by Alcon in connection with any such Infringement action, including joining in Legal Proceedings. Alcon shall bear the costs of any such Legal Proceedings, and shall be entitled to any damages,
account of profits and/or awards of costs recovered. 
 5.8    Settlements. The Parties shall reasonably consult
with each other before accepting any settlement or any judicial finding related to the Licensed Compound Patents which is reviewable by a higher authority.

Hundred and Twenty-Five Thousand Nine Hundred and Seventy-One United States Dollars and Seventy-Four Cents (US$2,725,971.74) shall be due on [***]. The second half of the Upfront Payment, i.e., Two Million
United States Dollars (US$2,000,000.00), shall be due [***].

 6.4    Calculation of Milestone Payments. Each Milestone Payment
shall be deemed earned as of the first achievement of the respective Milestone event, and is payable one time only (i.e. annual sales are not cumulative but calculated anew each annual period). 

6.5     Royalty Payments. 

(a)    Royalty Rates. As partial consideration for the licenses and rights granted to Oculis
hereunder, during the Royalty Term, Oculis will make royalty payments to Alcon on aggregate annual Net Sales of Licensed Products in the Field by Oculis and its Affiliates and sublicensees, as set forth below:

BECAUSE IT IS BOTH (I) NOT MATERIAL AND (II) CUSTOMARILY AND ACTUALLY TREATED BY THE REGISTRANT AS PRIVATE OR CONFIDENTIAL. 
  

 The Parties acknowledge that the above Royalty Rates include a [***] royalty owed to Apexigen under the
Apexigen Agreement on Oculis Net Sales (as defined in Article XVI, Section 16.28 of the Apexigen Agreement) of the Licensed Products (the “Apexigen Royalty”). Although such Apexigen Royalty will be taken into consideration by
Alcon for the purposes of calculating deductions and/or reductions in Royalties owed by Oculis to Alcon under the present Section 6.5 and will be deducted from amounts due to Alcon, the Parties agree that, as expressly authorised by the Third
Amendment to the Apexigen Agreement, Oculis shall pay directly to Apexigen the full [***] Royalty Rate (in the conditions and terms defined in Article VI of the Apexigen Agreement) on its Net Sales of the Licensed Products (the “Apexigen
Royalty”). 
 (b)    Royalty Term. Royalties set forth in Section 6.5(a) will
be payable on aggregate Net Sales of Licensed Products beginning from the date of the First Commercial Sale of any Licensed Product in any country in the Territory and shall continue to be paid in accordance with the terms of this Agreement until
the later of (a) the expiration of the last to expire Valid Claim of any Licensed Patent covering any such Licensed Product in such country; (b) the expiration of the period of data exclusivity in any country in the Territory; or
(c) twelve (12) years after First Commercial Sale of such Licensed Product in such country (the “Royalty Term”). As per Section 14.1.(b), upon the expiration of this Agreement, the license grant to Oculis in Section 2.1
shall continue on a worldwide, non-exclusive, perpetual, royalty-free, fully paid up basis. For the avoidance of doubt, and as per Section 14.8 (Survival), limitations set out in Section 2.2. (and in
particular Section 2.2.(a)) shall survive termination or expiration. For the avoidance of doubt, the Apexigen Royalty shall remain due by Oculis to Apexigen for as long as they are due under the Apexigen Agreement (the “Apexigen Royalty
Term”), including in the event that such Apexigen Royalty Term continues after the expiry of the Royalty Term and is thus no longer entitled to any deductions under Section 6.5.(c), (d) and (e). 

(c)    Valid Claim and Loss of Market Exclusivity: If, during the Royalty Term, the relevant Licensed Product is
(i) not covered by a Valid Claim in the applicable country in the Territory and/or (ii) there is a Loss of Market Exclusivity in such country, then for so long as there is no Valid Claim in such country during the Royalty Term and/or there
is a Loss of Market Exclusivity in such country during and until the end of the Royalty Term, the Net Sales for such country to be included in worldwide Annual Net Sales for the purpose of the calculation of Royalties due under Section 6.5(a)
will be reduced by [***] 
 [By way of example: [***]] 

(d)    Third Party Royalty. If Oculis reasonably determines that, in order to practice any Licensed Patent within
the scope of the license granted hereunder in connection with Commercialization of a Licensed Product in a country, it is necessary to obtain a patent license from a Third Party and to pay a royalty for such Licensed Product in such country, Oculis
may offset [***] of the amount of royalties payable by Oculis to such Third Party under the license agreement with such Third Party in respect of such patent license against amounts Oculis is obligated to pay Alcon hereunder for such Licensed
Product, but in no event shall such effect reduce by greater than [***] the royalties otherwise payable to Alcon for such Licensed Product for a particular Calendar Quarter, provided however, that Oculis shall be entitled to carry forward to the


  
 25 














 [***] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, IS OMITTED
BECAUSE IT IS BOTH (I) NOT MATERIAL AND (II) CUSTOMARILY AND ACTUALLY TREATED BY THE REGISTRANT AS PRIVATE OR CONFIDENTIAL. 
  

 
next Calendar Quarter a credit equal to the aggregate amount by which such Third Party royalties exceeded [***] of the royalties otherwise payable to Alcon for any preceding Calendar Quarter.
Notwithstanding the foregoing, the deduction set forth in this Section 6.5(d) shall neither apply to the royalties payable under the Apexigen Agreement nor apply to any license from a Third Party to the extent such license
is solely required to Develop, Manufacture or have Manufactured, and/or Commercialize the other component(s) of a Combination Product. 

(e)    Limitation on Deductions. With respect to the reductions in royalties provided for in Sections
6.5(c) and (d) taken together, in no event shall such reductions in royalties be such that at any given time the royalties to be paid under Section 6.5(a) shall be reduced by more
than [***]. Any amount that Oculis is entitled to deduct that is reduced by the limitation provided for in this Section 6.5(e) on the deduction shall be carried forward and Oculis may deduct such amount from subsequent
amounts due to Alcon until the full amount that Oculis was entitled to deduct is deducted. In the event all royalty and milestone payments due to be made by Oculis under this Agreement have been made and there remains not yet taken as a deduction
some amount of the full amount that Oculis was entitled to deduct, an amount corresponding to such remaining deduction shall be paid by Alcon to Oculis. 

7.     REPORTS AND PAYMENT TERMS 

7.1     Payment Terms. 

(a)    Oculis shall notify Alcon in writing within [***] after achievement of the applicable Milestone and Alcon shall
thereafter issue to Oculis an invoice substantially in the form provided by Alcon in respect of the applicable Milestone Payment. Oculis will pay such invoice to Alcon within [***] from the date of its receipt of the invoice. 

  
 26

BECAUSE IT IS BOTH (I) NOT MATERIAL AND (II) CUSTOMARILY AND ACTUALLY TREATED BY THE REGISTRANT AS PRIVATE OR CONFIDENTIAL. 
  

 (b)    Within [***] after each Calendar Quarter during the Term,
following the First Commercial Sale of a Licensed Product (on a Licensed Product-by-Licensed Product basis), Oculis will provide to Alcon a Sales and Royalty Report.
Alcon shall submit an invoice to Oculis with respect to the Royalty amount shown therein. Oculis shall then pay such Royalty amount within [***] after the date of its receipt of the invoice. 

(c)    All payments from Oculis to Alcon shall be made by wire transfer of immediately available funds in US Dollars to
the credit of such bank account or accounts as may be designated by Alcon in writing to Oculis from time to time. Any payment which falls due on a date which is not a Business Day may be made on the next succeeding Business Day. 

7.2    Currency Exchange Rate. All payments under this Agreement shall be payable in US Dollars. The Royalty amount
to be paid by Oculis in respect to the Net Sales of the Licensed Products in the Field in the Territory sold in a currency other than US Dollars shall be converted to the US Dollar equivalent using the buying rate for the applicable currency of
the country from which the royalties are payable, certified by the United States Federal Reserve Bank of New York, as published from time to time by the United States Federal Reserve Board on the Internet, at
http://www.federalreserve.gov/releases/h10/ or elsewhere, or if certain exchange rates are not published by the United States Federal Reserve Board on the Internet, then as published on oanda.com, in respect to the last Business Day of the Calendar
Quarter ending immediately prior to the date on which the applicable Royalty payment is due or the last date prior to such last Business Day for which such certified buying rate has been published by the United States Federal Reserve Board or
oanda.com, respectively 
 7.3    Taxes. In the event any payments to be made by Oculis to Alcon hereunder are
subject to deduction or withholding of any tax under applicable Law, Oculis shall deduct in full the respective amount from the payment due and pay the full amount withheld or deducted to the relevant taxing authority. Within [***] of making such
payment to the relevant taxing authority, Oculis shall deliver to Alcon proof of such payment. Each Party agrees to reasonably assist the other Party in lawfully claiming exemptions from and/or minimizing such deductions or withholdings under double
taxation Laws, treaties or similar circumstances. 
 7.4    Sales and Royalty Report. After the First Commercial
Sale in the Territory and within [***] after the end of each Calendar Quarter, Oculis will prepare and provide to Alcon a written report or reports substantially in the form set forth in Schedule J showing each of: (a) gross
sales; (b) Net Sales; (c) units sold; (d) all permitted reductions to or deductions from gross sales; (e) Royalties payable for Licensed Products in the Field in the Territory on a country-by- country basis in United States Dollars during the reporting period; (f) date of First Commercial Sale for each Licensed Product in each country, and (g) less Royalties actually paid to
Apexigen. For the avoidance of doubt, such written report shall also show details on the aforementioned (a) to (c) items for: (i) Oculis, its Affiliates and its sublicensees; (ii) last Calendar Quarter and year to date data, for
example, up to the last month of the last Calendar Quarter; and (iii) for each Licensed Product (“Sales and Royalty Report”). Sales and Royalty Reports shall be considered Information of Oculis. For the avoidance of doubt, as
agreed between the Parties and as indicated in Section 6.5.(a) above, the Apexigen Royalty shall be directly reported and paid by Oculis to Apexigen in the conditions set out in the Apexigen Agreement and for the Apexigen Royalty Term.

 7.5    Records and Audit
Rights. 
 (a)    Oculis shall keep or cause its Affiliates and sublicensees [***] to keep, complete, true and
accurate books and records in accordance with the Accounting Standards in relation to its obligations under this Agreement, including regarding Net Sales and the Sales and Royalties Report. Oculis will keep or have kept such books and records for at
least [***] following the Calendar Quarter to which they pertain. 
 (b)    Alcon shall have the right for a period of
[***] after receiving each Sales and Royalty Report to appoint an internationally-recognized independent accounting firm (hereinafter referred to as the “Auditor”) to inspect the relevant records of Oculis and its Affiliates or its
sublicensees [***] to verify such reports, statements, records or books of accounts, as applicable, in each case only if and to the extent relevant for verifying compliance by Oculis of its obligations under this Agreement; provided that
(i) any Auditor will have to enter into a non-disclosure agreement with Oculis, (ii) Alcon is entitled to no more than one audit per calendar year under this
Section 7.5(b), and (iii) Alcon can have audited a specific period no more than once. The Auditor shall have the right to disclose to Alcon and/or other Affiliates of Alcon its conclusions regarding any payments
owed or overpaid under this Agreement to the exclusion of all underlying data. 
 (c)    Oculis and its Affiliates and
sublicensees [***] shall make their records available for inspection by the Auditor during regular business hours at such place or places where such records are customarily kept, upon receipt of reasonable advance notice from Alcon of at least
[***], its Affiliate or designated independent accounting firm, to verify the accuracy of the Sales and Royalty Reports and compliance with this Agreement. Alcon agrees to, and to cause the Auditor to, hold in confidence all information received and
all information learned in the course of any audit or inspection, except to the extent that such information is not confidential and/or it is necessary to disclose it to enforce its rights under this Agreement or if disclosure is required by Law.

 (d)    Alcon shall pay for such audits, as well as its own expenses associated with enforcing its rights with respect
to any payments hereunder, except that, if an underpayment of more than [***] of the total payments due hereunder for the applicable Calendar Year is discovered, the reasonable fees and expenses charged by or incurred by the Auditor shall be paid by
Oculis. 
 (e)    In the event that the final result of the inspection reveals an undisputed underpayment by Oculis, the
underpaid amount shall be settled promptly to Alcon with interest thereon at [***], computed from the date such underpayment was due until the date that Oculis makes the underpayment. 

(f)    For the avoidance of doubt, the information provided by Oculis pursuant to this
Section 7.5 shall be deemed to be Information of Oculis for purposes of this Agreement. 

(g)    In consideration of the fact that, under Section 1.2.5 of the Third Amendment of the Apexigen Agreement,
Novartis shall only be relieved of its obligations to

ensure payments on Oculis Net Sales under the Apexigen Agreement upon Oculis having effectively paid the Apexigen Royalty, Oculis shall (i) keep accurate records of royalty reports sent to
Oculis and proof of payment of Apexigen Royalties made thereunder, and (ii) send Novartis, once per year, a copy such reports and proof of payments. Information communicated under this section shall be deemed to be Information of Oculis for

 If Oculis fails to provide Alcon in writing with the delivery address for the Inventory within [***] following
the Effective Date, Alcon shall send a written request to Oculis for the delivery address; and if Oculis fails to provide Alcon in writing with the delivery address for the Inventory within [***] following its receipt of Alcon’s written
request, then Alcon and/or its Affiliates shall be entitled to authorize [***] to destroy and dispose of the respective Inventory at Oculis’ cost and expense. For clarity, Inventory will comply with the respective specifications but will
otherwise be transferred “as is,” with no warranty, expressed or implied, including a warranty for a particular purpose or use.

records, without reference to the Information disclosed by the disclosing Party or its Affiliates under this Agreement.

regulations or any securities regulatory organization’s disclosure requirements, and/or (iii) communicate with current or potential lenders, investors, acquirers, or merger partners on a need-to-know basis under confidentiality provisions no less restrictive than those of this Agreement. 

(c)    In the event the recipient Party is required to disclose Information of the disclosing Party by Law or in
connection with bona fide legal process, such disclosure shall not be a breach of this Agreement, provided that the recipient Party (i) informs the disclosing Party as soon as reasonably practicable of the required disclosure; (ii) limits
the disclosure to the required purpose; and (iii) at the disclosing Party’s request and expense, assists in an attempt to object to or limit the required disclosure. 

15.4    Ongoing Obligation for Confidentiality. Upon early termination of this Agreement for any reason, each Party
and its Affiliates shall immediately (a) return to the other Party or destroy any Information supplied or disclosed by the other Party together with all hard copies thereof, except for (i) such copies as must be retained pursuant to
applicable Law, and (ii) one copy which may be retained in its confidential files for archive purposes; (b) destroy all notes and all summaries or extracts in any medium prepared by or on behalf of recipient derived from this Information;
and (c) use all best efforts to procure that all third parties, to which this Information was disclosed, destroy or erase any Information contained in any materials and documentation recorded in any memory device. 

15.5    Termination of Prior Confidentiality Agreement. This Agreement supersedes and replaces the Confidentiality
Agreement between the Parties dated February 12, 2018. All information exchanged between the Parties under such Confidentiality Agreement shall be deemed Information hereunder and shall be subject to the terms of this

keep arbitration costs to a minimum. Each Party must bear its own attorneys’ fees and associated costs and expenses, as well as an equal share of the fees and costs incurred by ICC and the arbitrators. The Parties shall use all reasonable
efforts to make witnesses available for the proceedings

(iii) to Novartis Pharma AG or any of its affiliates at any time, regardless of whether Alcon is, at the time of such assignment and/or novation, an affiliate of Novartis Pharma AG; provided however, that such assignment shall be subject to a
written agreement that (i) requires the assignee to comply with all applicable obligations of this Agreement, and (ii) is not in conflict with any term of this Agreement, and that Alcon shall give Oculis prior written notice at least [***]
before the execution of a binding agreement. 
 (c)    Notwithstanding Section 17.3(a), Oculis
may, without the consent of Alcon, assign and/or novate this Agreement or any of its rights or obligations to an Affiliate; provided however, that such assignment to an Affiliate shall be subject to a written agreement that (i) requires the
assignee to comply with all applicable obligations of this Agreement, and (ii) is not in conflict with any term of this Agreement. 

(d)    Notwithstanding Section 17.3(a), Oculis may, without the consent of Alcon, assign any of its rights under this
Agreement to a Third Party in the event of a Change of Control in Oculis, and: 
 (i)    Alcon shall have the right to
require that Oculis, the Third Party with whom such Change of Control is effected and each of their respective Affiliates, (1) adopt procedures reasonably calculated, as approved by Alcon (whereby Alcon shall be deemed to have given its
approval if within [***] from receipt of Oculis’ request to grant such approval, Alcon has not provided Oculis with a written answer detailing how to amend the suggested procedures so that they will be approved) to limit the dissemination of
Sensitive Information to only those Persons employed by or under contract with Oculis or its successor, in each case having a need to know such Sensitive Information in order for Oculis to perform its obligations and exercise its rights under this
Agreement; and (2) [***]. 
 (ii)    For the purpose of this Section 17.3(d),
“Change of Control” means, with respect to Oculis: (1) the sale, conveyance, transfer, or lease of all or substantially all of Oculis’ assets or business relating to this Agreement to any Third Party; (2) a merger,
reorganization or consolidation involving Oculis in which the total voting power of the stock of Oculis outstanding immediately prior thereto ceases to represent at least fifty percent (50%) of the combined voting power of the stock outstanding of
the surviving entity normally entitled to vote in elections of directors immediately after such merger, reorganization or consolidation; or (3) a Person or group of Persons acting in concert becoming the beneficial owner, directly or
indirectly, of more than fifty percent (50%) of the total voting power of the stock then outstanding of Oculis normally entitled to vote in elections of directors. 

(iii)    For the purpose of this Section 17.3(d), “Sensitive
Information” means [***]. 
 (e)    Any assignee shall assume all obligations of the assigning Party under this
Agreement (or the assigned portion in the case of any partial assignment), and no permitted assignment shall relieve the assignor of liability hereunder. Any attempted assignment in

contravention of this Section 17.2 will be null and void. Subject to the terms of this Agreement, this Agreement will be binding upon and inure to the benefit of the
Parties and their respective successors and assigns. 
 17.4    Injunctive Relief. The Parties understand and
agree that monetary damages may not be a sufficient remedy for breach of this Agreement and that each Party will be entitled to seek equitable relief, including injunction and specific performance for any such breach. Nothing contained in this
Agreement shall be construed as limiting a Party’s right to any other remedies it may have under this Agreement or in Law, including, without limitation, the recovery of damages for breach of this Agreement. 

17.5    Force Majeure. If and to the extent that either Party is prevented or delayed by Force Majeure from
performing any of its obligations under this Agreement and promptly so notifies the other Party in writing, specifying the matters constituting Force Majeure together with such evidence in verification thereof as it can reasonably give and
specifying the period for which it is estimated that the prevention or delay will continue, then the Party so affected shall be relieved of liability to the other for failure to perform or for delay in performing such obligations (as the case may
be), but shall nevertheless use its commercially reasonable efforts to resume full performance thereof. 

17.6    Notices. All notices, consents, waivers, and other communications under this Agreement must be in writing
and will be deemed to have been duly given when: (a) delivered by hand or by express courier service (in both instances with written confirmation of receipt), or (b) when received by the addressee, if sent by an internationally recognized
overnight delivery service (receipt requested), in each case to the appropriate addresses set forth below (or to such other addresses as a Party may designate by written notice):

 Each Party
may change its address for purposes of this Agreement by written notice to the other Party. 
 17.7    Data
Privacy. Due to the purpose of this Agreement both Novartis and Agency are considered Data Controllers. “Data Controller” means the natural or legal person which alone or jointly with others determines the purposes
for and the means of the processing of Personal Information. Without limitation of any provision of this Agreement, both parties agree to comply with all applicable local Data Protection Legislation governing the confidentiality, privacy and/or
security of information governed by applicable privacy law (“Personal Information”). Both parties shall implement adequate and reasonable safeguards to prevent the use or disclosure of Personal Information other than as provided for
in this Agreement, and to protect the confidentiality, integrity, and availability of such information. Both parties understand and agree that the confidentiality, privacy and security requirements contained in this Agreement also apply to any
permitted sub-contractors, temporary employees or other third-parties who process any Personal Information or any confidential or proprietary information relating to Novartis. At any time during the processing
of Personal Information, each party shall immediately (but no later than [***] from the date) inform the other of any data security breach involving Personal Information. Each party agrees to assist and cooperate with the other party concerning any
disclosures to affected data subjects, government or regulatory agencies and with any other remedial measures requested or required under any law. 

17.8    Waiver and Amendments. The failure of a Party to assert a right hereunder or to
insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. No waiver shall be effective unless it
has been given in writing and signed by the Party giving such waiver. No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party. 

17.9    Severability. Without prejudice to any other rights that a Party may have pursuant to this Agreement, every
provision of this Agreement is intended to be severable. If any provision of this Agreement shall be invalid or unenforceable, such invalidity or unenforceability shall not affect the other provisions of this Agreement, which shall remain in full
force and effect. The Parties hereto agree to consult each other and to agree upon a new stipulation which is permissible under the Law and which comes as close as possible to the original purpose and intent of the invalid, void or unenforceable
provision. 
 17.10    Entire Agreement. This Agreement constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof.

 17.11    Relationship of the
Parties. Nothing contained in this Agreement shall be deemed to constitute a partnership, joint venture, or legal entity of any type between Alcon and Oculis, or to constitute one as the agent of the other. Moreover, each Party agrees not
to construe this Agreement, or any of the transactions contemplated hereby, as a partnership for any tax purposes. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give any Party the power
or authority to act for, bind, or commit the other. 
 17.12    Expenses. Except as otherwise expressly provided
in this Agreement, each Party shall pay the fees and expenses of its respective lawyers and other experts and all other expenses and costs incurred by such Party incidental to the negotiation, preparation, execution and delivery of this Agreement.

 17.13    Further Assurances. Alcon and Oculis hereby covenant and agree without the necessity of any further
consideration, to execute, acknowledge and deliver any and all such other documents and take any such other action as may be reasonably necessary to carry out the intent and purposes of this Agreement. 

17.14    Headings. Titles or captions of articles and sections contained in this Agreement are inserted only as a
matter of convenience and for reference, and in no way define, limit, extend, or describe the scope of this Agreement or the intent of any provision hereof. 

17.15    English Language. This Agreement is written and executed in the English language. Any translation into any
other language shall not be an official version of this Agreement and in the event of any conflict in interpretation between the English version and such translation, the English version shall prevail. 

17.16    Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one (1) and the same instrument.
