•Beginning on the sixth anniversary of the Effective Date, and for each anniversary thereafter, $[***].

Such fees will accrue on the applicable anniversary date, and Surface will pay the applicable annual maintenance fee to Vaccinex within thirty (30) days following Surface’s receipt of Vaccinex’s invoice therefor.

c..Milestone Payments. Surface will pay to Vaccinex the milestone payments set forth in this Section 4.3 (Milestone Payments) with respect to the first achievement of the relevant milestone event for each Licensed Product. Each milestone payment set forth in this Section 4.3 (Milestone Payments) is payable only once per Licensed Product, and the total payments payable under this Section 4.3 (Development Milestone Payments) will in no event exceed $15,000,000 per Licensed Product. The milestone payments will accrue upon the achievement of the applicable milestone event, and Surface will promptly notify Vaccinex of such achievement, and pay the associated milestone payment within thirty (30) days following achievement of each milestone event described in this Section 4.3 (Milestone Payments).

For avoidance of doubt, a clinical trial that meets more than one definition of the type of clinical trial (such as a clinical trial with an adaptive design, which morphs from a Phase 1 Clinical Trial to a Phase 2 Clinical Trial), will be considered to be both of such clinical trials, and payment of all milestones achieved as a result of such consideration, will be due and owing.

d..Royalties.

1.Royalty Payments. Subject to the provisions of this Agreement, Surface will pay to Vaccinex, on a Licensed Product-by-Licensed Product basis during the Royalty Term for such Licensed Product, a royalty of [***] of Net Sales on Licensed Products sold in the Territory.

Surface will, and shall cause its Affiliates and Sublicensees, to permit all relevant books and records to be audited by an independent accounting firm selected by Vaccinex and reasonably satisfactory to Surface, or Surface’s Affiliate or Sublicensee, as applicable, from time-to-time during regular business hours at such place or places where such records are customarily kept to the extent requested by Vaccinex, but not more than once a year, provided that before beginning such audit, such independent accounting firm shall execute an agreement acceptable to Surface by which such independent accounting firm agrees to keep confidential all information reviewed during the audit. Vaccinex agrees to hold in strict confidence all information received and all information learned in the course of any audit, except to the extent necessary to comply with any law, regulation or judicial order. Such examination and audit is to be made at the expense of Vaccinex, except that it shall be at Surface’s expense if the results of the examination and audit reveal that Surface, its Affiliate or its Sublicensee underpaid Vaccinex by more than [***] for the year at issue.

a..Prosecution of Patent Rights.

At a reasonable time prior to the contemplated filing date, but in any event not less than [***] days prior, Surface shall submit to Vaccinex for review and comment a substantially completed draft of any patent application hereunder before Surface’s first filing of such patent application in any jurisdiction, and Vaccinex agrees to review and provide such comments, if any, to Surface on an expedited basis if necessary to avoid loss of patent rights. All expenses of Prosecuting such patents and patent applications shall be borne by Surface. Surface shall provide Vaccinex reports no less frequently than once per calendar year listing all patents and patent applications Prosecuted pursuant to the provisions hereof, including identification of the patents and patent applications by number and country, together with a brief description of the status of the prosecution or patent. Surface shall permit Vaccinex to review and comment on all patent applications, and related decisions and actions under this Section 5.1(b), provided that Surface will have all final decision-making rights over Prosecution decisions made with respect to the Selected Antibody Patent Rights. If Surface determines not to file or not to continue to Prosecute any patents or patent applications within the Selected Antibody Patent Rights for any country or region such that patent rights to a Selected Antibody would terminate for that country or region, then Surface shall promptly, and in any event not less than [***] days prior to the date in which a failure to file or respond would prejudice the rights of Vaccinex hereunder, notify Vaccinex in writing of such determination. Vaccinex may then Prosecute such patent or patent application at its own expense in that country or region. If Vaccinex exercises its rights under this Section 5.1(b) with respect to any such patent or patent application in any country or region that Surface has decided not to continue Prosecuting, the licenses set forth in this Agreement shall become non-exclusive but with the same license consideration terms (i.e., fees, payments, royalties) as set forth in Article

4, with respect to such patent or patent application, and patents issued therefrom in that country or region.

6.Cooperation.

In addition, Vaccinex agrees to cooperate with Surface in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country in the Territory where applicable to the Selected Antibody Patent Rights.

7.Disclosure. Each Party agrees that it will not make any public disclosure that would adversely impact the patentability of any Selected Antibody prior to filing of a protective patent in the United States, Europe, Canada and Japan.

8.Common Interest. All information exchanged between the Parties, or with or between the Parties’ outside patent counsel, including Prosecution counsel, regarding Prosecution of the Selected Antibody Patent Rights will be the Confidential Information of both Parties and potentially be privileged. In addition, the Parties acknowledge and agree that, with regard to such Prosecution of the Selected Antibody Patent Rights, the interests of the Parties are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Selected Antibody Patent Rights, including privilege under the common interest doctrine and similar or related doctrines.

a..Notice of Infringement. During the Term, each Party will inform the other Party promptly in writing of any alleged infringement of the Selected Antibody Patent Rights by a Third Party of which it becomes aware, and of any available evidence thereof.

b..Surface’s Right to Enforce and Defend Patent Rights. During the Term of this Agreement, Surface will have the first right, and control over in its sole discretion, but will not be obligated, to take any measures with respect to any Third Party’s activities concerning any product, method or service that infringes or misappropriates, or which Surface reasonably suspects infringes or misappropriates, the Selected Antibody Patent Rights (an “Infringing Product”), including (i) by initiating or prosecuting an infringement, misappropriation or other

appropriate suit or action against such Third Party in a court of law (each an “Infringement Action”) at its sole expense, or (ii) subject to Section 2.2 (Sublicenses), by granting adequate rights and licenses necessary for continued activities, including development, manufacture or commercialization, concerning any Infringing Product in the Territory to any Third Party who at any time has infringed or misappropriated, or is suspected of infringing or misappropriating, any Selected Antibody Patent Rights. Surface will also have the first right, and control over in its sole discretion, but will not be obligated, to defend any action or proceeding (including a declaratory judgment action or nullification action, re-examination, inter partes review, opposition, interference, post-grant review or other proceeding) brought by a Third Party in a court of law or before any patent office that challenges the patentability, validity or enforceability of any Selected Antibody Patent Rights or that seeks a determination that any Infringing Product does not infringe or misappropriate any Selected Antibody Patent Rights, and any appeals of the foregoing (any such action or proceeding a “Challenge Action”) in the Territory, at Surface’s expense. In furtherance of such right, Vaccinex hereby agrees that Surface may include Vaccinex as a party in any such Infringement Action or Challenge Action and that Vaccinex will provide reasonable assistance to Surface in connection with an Infringement Action or Challenge Action, in each case without expense to Vaccinex. If Surface elects not to exercise its first right with respect to such Infringing Product or Challenge Action, it shall promptly notify Vaccinex of the same. Upon receipt of such notice, Vaccinex shall have the right, but not the obligation, to take any of the measures stated in this Section 6.2 with respect to such Infringing Product or Challenge Action. Both Parties shall cooperate with each other in good faith in the prosecution of any such action or proceeding. The total cost of any such action commenced or defended solely by a Party will be borne by such Party and the other Party will receive a percentage of any recovery or damages for past infringement derived therefrom as follows: the recovered amounts will be used to reimburse the Parties for their reasonable and previously unreimbursed documented costs and expenses, including attorneys’ fees incurred in making such recovery (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses) with any remainder to be equally shared by the Parties.

c..Cooperation. With respect to any Infringement Action or Challenge Action, or any proceeding that a Party may institute to enforce the Selected Antibody Patent Rights pursuant to this Agreement, the other Party will, at the request and expense of the first Party, reasonably cooperate in all respects and, to the extent reasonably practicable, have its employees testify when requested and make available relevant records, information, samples, specimens, and other evidence upon request. If either Party reasonably determines that the other Party is an indispensable party to the action, the other Party hereby consents to be joined. In such event, both Parties shall have the right to be represented in that action by counsel of their own choice and at their own expense.

d..EU Unitary Patent System. Without limitation of Surface’s rights under Article 6 (Infringement Actions), Surface will have the exclusive right to opt-in and opt-out the Selected Antibody Patent Rights from the jurisdiction of the European Union Unified Patent Court when it becomes operational, in accordance with the Unified Patent Court (Regulation (E.U.) No 1257/2012) and its applicable Annexes and Rules of Procedure, as amended and from time to time in effect, and Vaccinex will not do so.

e..Patent Term Extensions. Surface will have the exclusive right to seek and obtain all available extensions of the Selected Antibody Patent Rights with respect to a Licensed Product, including any supplementary protection certificates, in any country in the Territory. Vaccinex will execute such authorizations and other documents and, at Surface’s expense, take such other actions as may be reasonably requested by Surface to obtain any such extensions, restorations and supplementary protection certificates of the Selected Antibody Patent Rights in the Territory.

c..No Other Warranties. EXCEPT AS SPECIFICALLY SET FORTH IN THIS ARTICLE 7, NEITHER PARTY MAKES ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, TITLE, VALIDITY, NON-INFRINGEMENT OR FITNESS FOR A PARTICULAR PURPOSE.

a..Indemnification by Surface. Surface will at all times, during the term of this Agreement and thereafter, indemnify, defend and hold harmless Vaccinex and its Affiliates, sublicensees, directors, officers, agents and employees from any and all liabilities, damages, losses, costs or expenses (including attorneys’ and professional fees and other expenses of litigation and/or arbitration) resulting from third party claims arising out of or resulting from: (i) the gross negligence or willful misconduct of Surface (or its directors, officers, employees or agents) hereunder; (ii) the breach by Surface of any representation, warranty or covenant in this Agreement; or (iii) the exercise or practice of the rights granted hereunder to Surface, including the development, manufacture, holding, use, testing, marketing, advertisement, sale or other disposition by Surface, its Affiliates or Sublicensees, of the Licensed Product (or any other product or service offered by Surface, and/or its Affiliates or collaborators), the Selected Antibody, or its related cell lines (or their progeny or derivatives, other biological materials, method, process, device or apparatus), except in each case (i)-(iii), to the extent caused by the gross negligence, willful misconduct or breach of this Agreement of or by Vaccinex.

b..Indemnification by Vaccinex. Vaccinex will at all times, during the term of this Agreement and thereafter, indemnify, defend and hold harmless Surface and its Affiliates, sublicensees, directors, officers, agents and employees from any and all liabilities, damages, losses, costs or expenses (including attorneys’ and professional fees and other expenses of litigation and/or arbitration) resulting from third party claims arising out of or resulting from: (i) the gross negligence or willful misconduct of Vaccinex (or its directors, officers, employees or

agents) hereunder; or (ii) the breach by Vaccinex of any representation, warranty or covenant in this Agreement; except in each case (i)-(ii), to the extent caused by the gross negligence, willful misconduct or material breach of Surface.

c..Indemnification Procedures. If a Party (the “Indemnitee”) intends to claim indemnification under this Article 8 (Indemnification; Limitation of Liability) it will promptly notify the indemnifying Party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends to claim such indemnification, and the Indemnitor will assume control of the defense thereof, with counsel of its choice; provided that Indemnitor will not settle any such proceeding in a manner that requires the Indemnitee to admit to any legal violation or assume any liability that is not paid for in its entirety by Indemnitor without Indemnitee’s prior written consent, not to be unreasonably withheld. The Indemnitee will have the right to retain its own counsel and participate in the defense thereof, with the fees and expenses to be paid at its own expense. The indemnity agreement in this Article 8 (Indemnification; Limitation of Liability) will not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor, which consent will not be withheld or delayed unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, will relieve such Indemnitor of any liability or obligation to the Indemnitee under this Article 8 (Indemnification; Limitation of Liability). The Party claiming indemnification under this Article 8 (Indemnification; Limitation of Liability), its employees and agents, will reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this indemnification.

a..Term. The term of this Agreement (the “Term”) will commence on the Effective Date and will continue in full force and effect until terminated in accordance with Section 9.2 (Termination).

b..Termination.

18.Termination for Convenience. Surface may terminate this Agreement at any time upon [***] days’ prior written notice to Vaccinex.

19.Termination for Cause. Either Party may terminate this Agreement in its entirety, effective upon written notice to the other Party, if the other Party materially breaches this Agreement and fails to cure such breach within [***] days after receiving written notice thereof, provided that if the alleged breaching Party disputes in good faith the existence or materiality of any such breach specified in the notice provided by the other Party, and the alleged breaching Party provides notice of such dispute within such [***] day period then such [***] day cure period will be tolled during the pendency of such dispute and the Party alleging such breach shall not have

the right to terminate this Agreement unless and until such dispute is resolved.

20.Payment Default. Notwithstanding Section 9.2(b) (Termination for Cause), if Surface shall at any time default in the payment of any royalty or other payment required by this Agreement, Vaccinex may, at its option, terminate this Agreement upon [***] days’ written notice, provided that if Surface disputes in good faith the existence of any such payment default specified in the notice provided by Vaccinex, and Surface provides notice of such dispute within such [***] day period, then such [***] day period will be tolled during the pendency of such dispute, provided such dispute is handled as an Expedited Dispute (as defined in Exhibit D). Vaccinex will not have the right to terminate this Agreement unless and until such Expedited Dispute is resolved, and provided, further that (a) if Surface has fully cured its default within such period, then the rights and licenses herein granted shall remain in force as if no breach or default had occurred and (b) if any payments are determined to be payable to Vaccinex following the resolution of the dispute, such payment shall be immediately payable with interest as of the original payment due date at the lower of (a) the maximum rate permitted by applicable law and (b) the rate of [***] per annum above “Prime” as defined in The Wall Street Journal on the original payment due date or, if unavailable, on the latest date prior to the payment due date on which such rate is available, calculated on a daily basis on the actual number of days elapsed from the payment due date to the date of actual payment.

21.Diligence Failure. Notwithstanding Section 9.2(b) (Termination for Cause), Vaccinex may terminate this Agreement in the event that Surface is in material breach of its diligence obligations under Section 3.1 (General Obligation) and fails to cure such material breach within [***] days after receiving written notice thereof from Vaccinex, provided that if Surface disputes in good faith the existence or materiality of any such breach specified in the notice provided Vaccinex, and Surface provides notice of such dispute within such [***] day period then such [***] day cure period will be tolled during the pendency of such dispute, and Vaccinex shall not have the right to terminate this Agreement unless and until such dispute is resolved.

22.Subject to applicable laws, Vaccinex may terminate this Agreement immediately upon written notice to Surface in the event that Surface, its Affiliate or Sublicensee Challenges (as defined below) any patent or patent application contained in the Vaccinex Program IP or Other Intellectual Property Rights (each a “Licensed Patent”) provided, however, that no such termination right shall apply to (i) any Challenge that is commenced by a Sublicensee where Surface demands that such

Sublicensee withdraw such Challenge promptly after Surface becomes aware of such Challenge and terminates the sublicense agreement with the applicable Sublicensee if such Sublicensee does not withdraw such Challenge within [***] days after receipt of notice from Surface, or (ii) providing documents or testimony in response to any discovery requests or court order in a valid legal process. As used in this Section 9.2(e), “Challenge” means to Contest the validity or enforceability of any Licensed Patent in whole or in part, in any court, arbitration proceeding, or other tribunal, including the USPTO, the United States International Trade Commission, or any foreign equivalent thereof. For the avoidance of doubt, the term “Contest” means: (a) commencing, filing, joining in, or assisting a Third Party in filing an action under 28 U.S.C. §§ 2201-2202, seeking a declaration of invalidity or unenforceability of any Licensed Patent or any portion thereof; (b) commencing, filing, joining in, or assisting a Third Party in filing a petition under 35 U.S.C. § 311 to institute inter-partes review of any Licensed Patent or any portion thereof; (c) commencing, filing, joining in, or assisting a Third Party in filing a petition under 35 U.S.C. § 321 to institute post-grant review of any Licensed Patent or any portion thereof; or (d) any foreign equivalents of subsection (a) through (c) applicable in any country. As used herein, the term “Contest” does not include any action taken by Surface, its Affiliate or Sublicensee for the sole purpose of complying with the duty to disclose information material to patentability as set forth in 37 CFR 1.56 or any foreign equivalent thereof, or to exercise its rights to Prosecute the Selected Antibody Patent Rights pursuant to Article 5.

c..Effects of Termination. Upon termination of this Agreement pursuant to Section 9.2 (Termination), all of Surface’s unpaid payment obligations to Vaccinex pursuant to Article 4 (License Consideration) will terminate, provided that neither Party will be released from any obligation that accrued prior to the effective date of such termination. Upon termination of this Agreement pursuant to Section 9.2 (Termination), all rights granted by Vaccinex to Surface under Article 2 (Grant), including Vaccinex Program IP (including Vaccinex’s interest in rights jointly controlled with Surface), will revert to Vaccinex. Surface and any Sublicensee may, after the effective date of such termination, sell all Licensed Products that were produced prior to the effective date of such termination but in any event for no longer than [***] months after the effective date of such termination.

d..Effect of Termination on Sublicenses. In the event of any termination of this Agreement pursuant to Section 9.2 (Termination), where such termination has not been caused by any action or inaction on the part of any Sublicensee or by any material breach by such Sublicensee of its obligations under its Sublicense from Surface, and termination of this Agreement will be without prejudice to the rights of each non-breaching Sublicensee, and Vaccinex will enter into a license agreement directly with each such Sublicensee (the “New License Agreement”) on substantially the same terms and conditions as those set forth in this Agreement; provided, however, that (a) the New License Agreement will provide that in no event

will such Sublicensee be liable to Vaccinex for any actual or alleged default by Surface of this Agreement, (b) the scope and territory of the license grant under the New License Agreement will be the same as that granted by Surface to such Sublicensee pursuant to the Sublicense between Surface and such Sublicensee, (c) the financial terms of any New License Agreement will be such that Vaccinex will receive no less than the same consideration that it would have received under this Agreement had it not been terminated, and (d) Vaccinex will not have any obligations under the New License Agreement that are greater than or inconsistent with the obligations of Vaccinex under this Agreement. Each such Sublicensee will be deemed a third party beneficiary of this Section 9.4 (Effect of Termination on Sublicenses) with the right to enforce it directly against Vaccinex.

e..Effect of Termination on IP. Effective upon termination of this Agreement, Vaccinex shall have the option for a period of [***] days to enter into good faith negotiations with Surface for an exclusive, worldwide license (with rights to sublicense) under all intellectual property, including without limitation, pre-clinical or clinical data, regulatory approvals and/or submissions, then owned or Controlled by Surface as of the effective date of termination as reasonably necessary to enable Vaccinex to engage in exclusive development and commercialization of the Selected Antibody and/or the applicable Licensed Product(s).

f..Survival. The following sections of this Agreement along with applicable definitions in Article 1 (Definitions) applicable thereto will survive termination or expiration of this Agreement: Section 4.8(c) (Records and Audit), Section 9.3 (Effects of Termination), Section 9.4 (Effect of Termination on Sublicensees), Section 9.5 (Effect of Termination on IP), Section 9.6 (Survival), Article 8 (Indemnification; Limitation of Liability), Article 10 (Confidentiality) and Article 11 (Miscellaneous). Except as otherwise provided in this Section 9.6 (Survival), all other provisions of this Agreement will terminate upon the termination of this Agreement.

a..Non-Disclosure. As used herein, the term “Confidential Information” includes any information that may be disclosed by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in connection with this Agreement, regardless of whether such information is specifically designated as confidential and regardless of whether such information is in oral, written, electronic or other form, provided that where such information is disclosed in oral form if the Confidential Information is not of a nature that should reasonably be understood by the Receiving Party as being confidential, then to be considered Confidential Information for the purposes of this Agreement, the Disclosing Party must confirm in writing that such information is to be treated as Confidential Information within [***] days of such disclosure. The Receiving Party will hold Confidential Information in confidence using the same degree of care that it employs for its own highly-sensitive confidential or proprietary information, which will in no event be less than a reasonable standard of care and will use and disclose the Disclosing Party’s Confidential Information only for the purpose of performing its obligations and exercising its rights under this Agreement. The Receiving Party may permit those directors, officers,

employees, consultants and advisers who have a need to know the Disclosing Party’s Confidential Information to access such Confidential Information, provided that such employees are subject to confidentiality obligations that are no less stringent than those under Article 10 (Confidentiality). Notwithstanding the foregoing, Surface may disclose the Confidential Information received from Vaccinex to its advisors or actual or potential acquirers or Sublicensees if such advisors and actual or potential acquirers or Sublicensees agree prior to disclosure to be bound by confidentiality obligations no less stringent than those under Article 10 (Confidentiality). The Receiving Party’s obligations under this Section 10.1 (Non-Disclosure) will continue throughout the Term and for five (5) years following the termination or expiration of this Agreement. The existence and terms of this Agreement shall be the Confidential Information of both Parties.

b..Exceptions. The confidentiality and non-use obligations set forth in Section 10.1 (Non-Disclosure) will not apply to Confidential Information that the Receiving Party can demonstrate by competent written proof: (a) was known by the Receiving Party without restriction prior to disclosure under this Agreement; (b) was lawfully disclosed to the Receiving Party by a Third Party without an obligation of confidentiality; (c) entered the public domain through means other than an unauthorized disclosure or other breach of this Agreement by the Receiving Party; (d) was independently developed by the Receiving Party without knowledge or use of or access to Confidential Information disclosed by the Disclosing Party under this Agreement; (e) was published or publicly disclosed in accordance with the terms of this Agreement; or (f) to the extent such information can be shown to be necessary to file a patent application subject to Section 5.1. Each Party may use or disclose Confidential Information disclosed to it by the other Party to the extent such use or disclosure is reasonably necessary in (i) filing or prosecuting patent applications, (ii) conducting clinical trials, (iii) making a permitted sublicense or otherwise exercising its rights hereunder.

c..Disclosure Required by Law. Notwithstanding Section 10.1 (Non-Disclosure), limited disclosure of Confidential Information will not be prohibited to the extent such Confidential Information is required to be produced under applicable law. If a Receiving Party is required by law, regulation, court order, or request by an agency of a government to disclose any of the Confidential Information, it will: promptly notify the Disclosing Party, reasonably assist the Disclosing Party to obtain a protective order or other remedy of Disclosing Party's election, and provide prior review of any disclosure to Disclosing Party. Only that portion of the Confidential Information that is legally required will be furnished and reasonable efforts will be made to obtain assurance that the Confidential Information will be maintained in confidence.

d..Publication. Surface may publish or present the results of research or development carried out on any Selected Antibody or Licensed Product in its sole discretion, provided that any publication or presentation that includes Vaccinex’s Confidential Information, or relates to Other Vaccinex Intellectual Property Rights, shall be subject to (i) Sections 10.1-10.3 hereto, and (ii) the prior review by Vaccinex, such review period not to exceed [***] days, and Surface shall consider Vaccinex’s comments in good faith.

e..Publicity. Vaccinex may, subject to Surface’s review and approval, issue a press release announcing the Parties' entry into this Agreement, provided that such press release shall not identify the specific indications of the Selected Antibody and Licensed Product hereunder.

a..Force Majeure. Neither Party shall be responsible to the other for failure or delay in performing any of its obligations under this Agreement or for other non-performance hereof (other than failure to pay) provided that such delay or non-performance is occasioned by a cause beyond the reasonable control and without fault or negligence of such Party, including, but not limited to earthquake, fire, flood, explosion, discontinuity in the supply of power, court order or governmental interference, or act of God, and provided that such Party will inform the other Party of such event as soon as is reasonably practicable and that it will use commercially reasonable efforts to perform its obligations immediately after the relevant cause has ceased its effect.

b..Validity. Should one or several provisions of this Agreement be or become invalid, then the Parties shall substitute for such invalid provisions valid ones, which in their economic effect come so close to the invalid provisions that it can be reasonably assumed that the Parties would have contracted this Agreement with those new provisions. In the event that such provisions cannot be determined, the invalidity of one or several provisions of the Agreement shall not affect the validity of the Agreement as a whole, unless the invalid provisions are of such essential importance for this Agreement that it is to be reasonably assumed that the Parties would not have contracted this Agreement without the invalid provisions.

c..Disputes. Any claim, dispute or controversy arising out of or in connection with or relating to this Agreement shall be submitted for adjudication in Federal District Court in the Southern District of New York, USA.

d..Notices. Any legal notice required or permitted to be given under this Agreement shall be in writing and shall be sent by expedited delivery or emailed with receipt confirmed in writing, as follows and shall be effective upon receipt:

Either Party may update the contact information in this Section 11.4 upon written notice to the other Party by email with receipt confirmed in writing.

e..Governing Law. Except as otherwise set forth in this Agreement the validity, performance, construction, and effect of this Agreement shall be governed by the laws of the state of New York, without regard to its conflict of law rules.

f..Entire Agreement. This Agreement, if executed, constitutes the entire agreement between the Parties with respect to the subject matter within and supersede all previous agreements, whether written or oral. This Agreement shall not be changed or modified orally, but only by an instrument in writing signed by both Parties.

g..Waiver. No waiver or release of any obligation under or provision of this Agreement shall be valid or effective unless in writing and signed by the waiving Party. The failure of either Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of such obligation. Waiver of any provision hereunder or of any breach of any provision hereof shall not be deemed to be a continuing waiver or a waiver of any other breach of such provision (or any other provision) on such occasion or any succeeding occasion.

h..Assignment. The rights of either Party under this Agreement may not be assigned, and the duties of either Party under this Agreement may not be delegated, without the prior written consent of the other Party, which consent shall not be unreasonably withheld; provided, however, that either Party may assign this Agreement without prior written consent to an Affiliate of such Party or to a party which acquires all or substantially all of that Party’s business to which this Agreement relates, whether by merger, sale of assets or otherwise.

i..Export. Each Party acknowledges that the laws and regulations of the U.S. restrict the export and re-export of commodities and technical data of U.S. origin. Each Party agrees that it will not export or re-export restricted commodities or the technical data of the other Party in any form without the appropriate U.S. and foreign government licenses.

j..Headings. Any headings and captions used in this Agreement are for convenience and reference only and are not a part of this Agreement.

k..Independent Contractors. The relationship between Vaccinex and Surface hereunder will be that of independent contractors and neither Party shall have the authority to bind or commit the other to any third party. Nothing in this Agreement will be construed to create a joint venture, partnership, agency or employer-employee relationship between the Parties and Vaccinex shall be solely responsible for all employment and withholding taxes applicable to the services provided by its employees and contractors under this Agreement.

l..NO INDIRECT DAMAGES. EXCEPT FOR DAMAGES RESULTING FROM A PARTY’S BREACH OF CONFIDENTIALITY OR OF SECTIONS 7.1(b), 7.1(f) OR 7.2(c), OR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OR IN CONNECTION WITH A PARTY’S INDEMNIFICATION OBLIGATIONS HEREUNDER, NEITHER PARTY WILL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL, MULTIPLE, PUNITIVE, EXEMPLARY OR OTHER INDIRECT DAMAGES, AND NEITHER PARTY WILL BE RESPONSIBLE FOR LOST PROFITS OR LOST REVENUES, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES.

m..Counterparts. This Agreement may be executed in any number of counterparts (which may be transmitted in the form of a facsimile or pdf), each of which shall be an original, and all of which shall constitute together but one and the same document.

n..Construction. Whenever the singular number is used in this Agreement and when required by the context, the same shall include the plural and vice versa, and the masculine gender shall include the feminine and neuter genders and vice versa. The words “include” and “including” shall mean respectively includes and including without limitation. The word “or” shall not be deemed to be used in the exclusive sense and shall instead be used in the inclusive sense to mean “and/or.” Each Party signing this Agreement acknowledges that such Party has had the opportunity to review this Agreement with legal counsel of such Party’s choice, and there shall be no presumption that ambiguities shall be construed or interpreted against the drafter.

IN WITNESS WHEREOF, the Parties have duly executed this Agreement as of the Effective Date.
