In such circumstances (but not in any circumstance where this Agreement has been terminated by Nanomerics for breach by Virpax, or by Virpax at will) Virpax, its Affiliates and Sub-licensees shall be allowed to continue Exploiting such Licensed Product and using all Licensed Know-How and Joint Know-How in connection therewith on a non-exclusive basis in such country with no further consideration to Nanomerics.

4. Delivering the Program

4.1 Information Disclosure; Assistance. Nanomerics shall, and shall cause its Affiliates to, at Virpax’s cost but without additional compensation, disclose and make available to Virpax, in whatever form Virpax may reasonably request, for the purposes of technology transfer, Regulatory Documentation, Licensed Know-How, Licensed Improvements and any other Information claimed or covered by any Licensed Patent or otherwise relating, directly or substantially, to the Compound or Licensed Products, as soon as reasonably practical after the Effective Date (and thereafter during the Term as may be reasonably requested by Virpax from time to time) to the extent not done so already and thereafter promptly after the earlier of the development, making, conception or reduction to practice of each such item of Regulatory Documentation, Licensed Know-How, Licensed Improvement or other Information.

competitive harm if publicly disclosed.

4.2 Diligence Obligations. Effective from the Funding Completion Date, Virpax undertakes to (i) use Commercially Reasonable Efforts at its own cost and expense to develop at least one Licensed Product and to conduct all development necessary to obtain Health Registration Approvals for a Licensed Product in each of the Major Markets in the Territory, and (ii) use Commercially Reasonable Efforts to Exploit such Licensed Product in each of the Major Markets in the Territory, provided, however, that the performance of such obligations including any Exploitation by Virpax, are not hindered or affected by any act or omission of Nanomerics.. For the avoidance of doubt, Virpax shall not be obligated to obtain Health Registration Approval for, or commercialise, more than one Licensed Product in any Major Market. In the event that Virpax, in consultation with Nanomerics, decides to discontinue the development or commercialisation of a Licensed Product in favour of another Licensed Product, its obligations under this Section 4.2 shall cease with respect to such initial Licensed Product in favour of such other Licensed Product. Virpax shall perform its obligation under this Section 4.2 in good scientific manner and in compliance in all material respects with all Applicable Law. Virpax shall have no other obligations towards Nanomerics, express or implied, to Exploit Licensed Products in the Territory. Notwithstanding anything herein to the contrary, Virpax shall be deemed not to have met the diligence obligations in this Section 4.2 should it have failed to dose the first subject in (and thereafter diligently pursue in good faith) a Phase I Clinical Trial of a Drug Product or equivalent formal clinical study, dependent on the appropriate regulatory pathway, within twelve (12) months of the Funding Completion Date.

4.3 Reporting Virpax shall provide Nanomerics (through JRC or otherwise) with quarterly progress reports on the clinical development of Licensed Products in the Territory. Such report shall cover general information on Virpax’s clinical development activities in the previous Calendar Quarter, a summary of the activities planned in the next twelve (12) months, and a timetable of planned and actual submissions for Health Registration Approvals. Virpax shall keep Nanomerics updated in reasonable detail with respect to submissions for Health Registration Approvals, and progress therewith. In any event, if and when a Health Registration Approval is obtained in any country of the Territory, Virpax shall promptly inform Nanomerics of such Health Registration Approval.

4.4 Conduct of the Program. The Program shall be performed by Virpax in the Territory. Under the direction and supervision of the JRC, Virpax shall (a) perform or cause to be performed its obligations under the Program in good scientific manner and in compliance in all material respects with all Applicable Law, including good laboratory practices and good clinical practices, and (b) allocate sufficient time, effort, equipment and skilled personnel to complete such activities successfully and promptly. Following the Effective Date, Virpax shall promptly commence the Program, provided, however, that Virpax shall not be obligated to initiate any activities under the Clinical Development Plan until the Funding has been fully received by Virpax or Virpax has notified Nanomerics in accordance with section 13.5.1.1 that it has secured equal or greater funding from a Third Party source which is available and intended for the Program.

4.5 Cooperation. Each Party shall cooperate with any and all reasonable requests for assistance from the other Party with respect to the activities under the Program, including by making its employees, consultants and other scientific staff available upon reasonable notice during normal business hours at their respective places of employment to consult with such other Party on issues arising in connection with the Program.

4.6 Regulatory Records. Nanomerics and Virpax each shall maintain, or cause to be maintained, records of its respective activities under the Program in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes, which shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of its respective activities under the Program, which shall record only such activities and shall not include or be co-mingled with records of activities outside the scope of this Agreement, and which shall be retained by such Party for at least five (5) years after the termination of this Agreement, or for such longer period as may be required by Applicable Law. Each Party shall have the right, during normal business hours and upon reasonable notice, to inspect and copy any such records.

4.7 Regulatory Pathway. The Parties expressly acknowledge and agree that as of the Effective Date, Virpax intends to develop a Drug Product and does not intend to develop a Medical Device Product. Nanomerics expressly acknowledges and agrees that the decision to change regulatory pathways is solely within Virpax’s discretion and, notwithstanding anything to the contrary hereunder, Virpax is under no obligation to develop a Medical Device Product.

4.8 Device Selection. The decision regarding which device Virpax will use for the delivery of the Licensed Product is solely within Virpax’s discretion. If, however, Virpax would like to use the Device for delivery of the Licensed Product, at any time after Virpax makes the Payment specified in Section 7.3 (a), Virpax may provide written notice to Nanomerics that it would like to use the Device for delivery of the Licensed Product. If Nanomerics approves of such use, which approval it will not unreasonably withhold, condition or delay, Nanomerics will grant to Virpax the right to use such Device. The date that Nanomerics provides to Virpax its written approval shall be the “Device Condition Date”.

5. Management of the Program

5.1 Responsibilities of JRC. The Parties shall establish a Joint Research Committee (the “JRC”) to oversee the initiation, planning and performance of the activities under the Program. In particular, the responsibilities of the JRC shall include: (a) establishing prioritization criteria for specific components under the Program; (b) determining within thirty (30) days of the completion of each stage of the Program whether the completion thereof has been successful and deciding whether or not to continue the Program into the next stage (i.e., making “stop/go decisions”); (c) monitoring workflow and overall Program progress; (d) ensuring timely and appropriate collaboration in the filing of Patent applications; (e) assigning tasks and responsibilities taking into account each Party’s respective specific capabilities and expertise in order to avoid duplication and enhance efficiency and synergies; (f) monitoring timely execution of the Program; and (g) reviewing and proposing to the Parties any amendments to Program.

5.2 Formation of JRC. The JRC shall consist of up to six (6) members with the requisite experience and seniority to enable them to make decisions on behalf of the Parties with respect to the Program, with equal numbers appointed by each Party, which shall include a Co-Chair to be designated by each Party. Each Party shall have the right to replace its respective JRC representatives upon written notice to the other Party, provided that any such substitute representative shall have substantially the equivalent experience and seniority as the representative that such person replaces.

5.3 Disputes. The JRC shall endeavour to reach consensus on all matters brought before it with each Party having a single vote, irrespective of the number of representatives actually in attendance at a meeting; provided, however, that in the event the JRC is unable to resolve an outstanding matter before it, such matter shall be resolved in good faith by the Parties’ CEOs. Any final decision mutually agreed to by the CEOs of the Parties shall be in writing and shall be conclusive and binding on the Parties. If such resolution is not achieved by the CEOs within thirty (30) days from the date the matter in dispute is first brought to their attention, and this occurs after start of clinical trials hereunder in regard of a Licensed Product, the dispute shall be resolved in accordance with Virpax’s position (except in the case of disputes relating to whether payment is due Nanomerics under this Agreement, which shall be resolved in accordance with Article 17). Any such dispute not resolved by the CEOs prior to start of such clinical trials shall be resolved in accordance with Article 17.

5.4 Meetings. The JRC shall meet quarterly and more frequently when required. The meetings will be held in person or by teleconference or videoconference. A quorum of the JRC shall exist whenever there is present at a meeting each of the Co-Chairs or their respective designees. In addition, the JRC may act without a formal meeting by a written memorandum signed by the Co-Chairs of the JRC. Whenever any action by the JRC is required hereunder during a time period in which the JRC is not scheduled to meet, either Co-Chair shall have the right to call a special meeting or the Co-Chairs may cause the JRC to take the action without a meeting in the applicable time period. Any such additional meetings shall be held at places and on dates selected by the Co-Chairs.

5.5 Expenses. Nanomerics and Virpax each shall bear their respective expenses of its JRC members related to such members’ participation on the JRC and attendance at JRC meetings.

5.6 Minutes. The JRC shall keep accurate minutes of its deliberations, which minutes shall record all proposed decisions and all actions recommended or taken and confirmation of any Program Milestones that have been reached. The Parties, on an alternating basis, shall prepare and circulate the draft minutes. Draft minutes shall be edited by the Co-Chairs and shall be issued in final form only with the approval and agreement of the Co- Chairs.

5.7 Dissolution of JRC. Following the completion of the Program the JRC shall be dissolved and Nanomerics shall provide Virpax with consultation services as Virpax may reasonably request during the remainder of the Term, including by making Nanomerics’ employees, consultants and other scientific staff available upon reasonable notice during normal business hours to consult with Virpax, its Affiliates or Sub- licensees on issues arising in connection with Exploitation of the Licensed Products. Such services shall be provided on reasonable commercial terms agreed in good faith by the Parties.

6. Ownership of Results from the Program

6.1 Virpax shall exclusively own all the Virpax Results, and Nanomerics shall exclusively own all the Nanomerics Results which Nanomerics Results shall be included in the licenses granted to Virpax pursuant to Section 3.1.

6.2 Each Party shall promptly disclose to the other in writing the development, making, conception or reduction to practice of any Results, and provide each other with reasonable assistance, where relevant, with respect to any efforts of the owning party to secure intellectual property protection for any of the Results.

6.3 Virpax hereby grants to Nanomerics the non-exclusive, perpetual, royalty free right and license to use those Virpax Results referable specifically to the Products for regulatory purposes and uses which comply with Nanomerics’ non-compete obligations as specified in Section 3.3.2 and not in violation of the license granted to Virpax hereunder.

6.4 Nanomerics shall, and does hereby, assign, and shall cause its Affiliates and its and their employees and agents, as applicable, to so assign, to Virpax, without additional compensation, such right, title and interest in and to any Virpax Results. Virpax shall, and does hereby, assign, and shall cause its Affiliates and its and their employees and agents, as applicable, to so assign, to Nanomerics, without compensation, such right, title and interest in and to any Nanomerics Results.

6.5 Should this Agreement be terminated for any reason prior to the Funding Completion Date, ownership of the Virpax Results shall be transferred to Nanomerics and Virpax shall assign, and shall cause its Affiliates and its and their employees and agents, as applicable, to so assign, to Nanomerics, without compensation, such right, title and interest in and to any Virpax Results.

6.6 Assignment and transfer of Ownership of all such Results shall occur instantly and automatically and shall not require any further deeds or documents to be exchanged between the Parties, except as required by the party taking assignment.

7. Consideration

7.1 Total Obligation. The milestone and royalty payments payable by Virpax to Nanomerics pursuant to this Article 7 represent all of Virpax’s financial obligations to Nanomerics under this Agreement. The Parties agree to act in good faith towards each other and their respective obligations regarding the consideration and Payments, including with respect to the assessment of whether Payments are payable.

Certain identified information has been excluded because it is both not material and would likely cause
competitive harm if publicly disclosed.

7.2 Payment in the Event of a Change of Control. In the event of a Virpax Change of Control that occurs prior to the dosing of the first subject in the first Phase II Clinical Trial for the first Licensed Product, Virpax shall pay to Nanomerics the following one-time payment based on the value received by Virpax as a result of the Change of Control within thirty (30) days following the closing date of the Change of Control:

(a) If the value received by Virpax is equal to or below [**], Virpax does not owe any payment to Nanomerics;

(b) If the value received by Virpax is more than [**] but equal to or less than [**], Virpax shall pay Nanomerics [**]; or

(c) If the value received by Virpax is more than [**], Virpax shall pay Nanomerics [**].

7.3 Program Milestones. Upon achievement of each milestone specified below (each a “Program Milestone”), Virpax shall, within the timescale specified, make the corresponding non-refundable payment to Nanomerics, as follows:

(a) a payment of U.S.$[**] within thirty (30) days following the Funding Completion Date;

(b) a payment of U.S.$ [**] within thirty (30) days following successful completion of the first Phase II or Pivotal Clinical Trial, as the case may be, with respect to a Licensed Product in the Territory; and

(c) a payment of U.S.$ [**] within thirty (30) days following first receipt by Virpax of an NDA approval or a PMA approval, as the case may be, for a Licensed Product in the United States.

7.4 Grant of Rights outside the Territory. Upon first submission by Virpax of an application for NDA approval or a PMA approval, as the case may be, for a Licensed Product in the United States, Nanomerics may elect, at its sole discretion by providing written notice to Virpax, to forego certain portions of milestone payments (as set forth below) in consideration of Virpax providing to Nanomerics:

[**]

In the event that Nanomerics exercises its rights under this Section 7.4, Nanomerics will forego the following portions of the following milestone payments, which Virpax may choose in its sole discretion:

(a) $[**] of the $[**] NDA approval milestone in Section 7.3(c) (i.e. reducing it to $[**]), or

(b) $[**] of the first commercial milestone payment in Section 7.6(a) of $[**] (i.e. reducing it to $[**]).

7.5 Supply of Compound. Upon achievement of the Program Milestone specified in Section 7.3(a), Nanomerics may elect, at is sole discretion by providing written notice to Virpax, to forego $[**] of the $1,000,000 milestone payable on completion of the first Phase II /Pivotal Clinical Trial in Section 7.3(b) in consideration of Virpax providing to Nanomerics, on or before a date reasonably specified by Nanomerics, [**].

Certain identified information has been excluded because it is both not material and would likely cause
competitive harm if publicly disclosed.

7.6 Commercial Milestones. Upon achievement of each milestone specified below (each a “Commercial Milestone”), Virpax shall, within the timescale specified, make the corresponding non-refundable payment to Nanomerics, as follows:

(a) a payment of US$ [**] within thirty (30) days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales for all Licensed Products exceeds US$ fifty million (50,000,000);

(b) a payment of US$ [**] within thirty (30) days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales for all Licensed Products exceeds US$ one hundred million (100,000,000); and

(c) a payment of US$ [**] within thirty (30) days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales for all Licensed Products exceeds US$ three hundred million (300,000,000).

While each Program Milestone and Commercial Milestone is payable once only, more than one Commercial Milestone may be payable with respect to Annual Net Sales achieved in the same Calendar Year. For example, if in Calendar Year “A” Annual Net Sales exceed US$ three hundred million (300,000,000) and in all previous Calendar Years, Annual Net Sales had been less than US$ fifty million (50,000,000) and so no Commercial Milestones had previously been paid, in Calendar Year A, all three Commercial Milestones pursuant to Sections 7.6.(a), 7.6(b) and 7.6(c) totaling US$ [**] would be payable, with Annual Net Sales of US$ 50,000,000, US$ 100,000,000 and US$ 300,000,000 all having been first exceeded in that Calendar Year A.

7.7 Upfront and Milestone Payments by Sublicensee. Within thirty (30) days of receipt by Virpax of any Third Party Sublicense Payment, Virpax shall pay to Nanomerics a non- refundable amount, equal to either:

(a) [**] of such Third Party Sublicense Payment (if such Third Party Sublicense Payment is received prior to dosing of the first subject in any Phase I Clinical Trial); or

(b) [**] of such Third Party Sublicense Payment (if such Third Party Sublicense Payment is received after dosing of the first subject in any Phase I Clinical Trial).

7.8 Each of the Program Milestones and Commercial Milestones set forth in this Article 7 shall be payable only once under this Agreement. Further, in the event that Virpax discontinues the Exploitation of a given Licensed Product in favour of another Licensed Product, any milestones paid to Nanomerics with respect to such first Licensed Product shall be credited against the equivalent milestones, if any, due with respect to such subsequent Licensed Product.

7.9 Royalties. In addition to the foregoing payments, Virpax shall, subject to Section 7.10, pay Nanomerics a royalty of [**] of the [**] of Licensed Products in the Territory throughout the Royalty Term.

7.10 Reduction of Royalty.

(a) Royalty Stacking. If, during the Term, Virpax enters into an agreement with a Third Party in order to obtain a license under a patent right of a Third Party that is necessary for Virpax, its Affiliates or any sublicensee to Exploit any Licensed Product (other than with respect to the use as part of a Licensed Product of a delivery device other than the Device, for which the cost shall be solely Virpax’s responsibility), then, upon entry into any such agreement and thereafter during the remainder of the period during which Virpax owes royalties to Nanomerics hereunder, the amounts payable under Article 7.9 hereof shall be reduced by [**] of all amounts payable by or on behalf of Virpax to such Third Party in connection with obtaining such rights; provided however, that in no event shall such amounts payable to Nanomerics be reduced as a result of this Section by more than [**] of the royalties under Article 7.9 otherwise due to Nanomerics in a particular Calendar Quarter. For the purposes of this Section 7.10, the Parties’ respective alliance managers shall endeavour to agree in good faith whether a Third Party license is “necessary”. A Third Party license which results in an objectively demonstrable and material (relative to the existing value) increase in commercial value of the Product, the Compound, and/or its or their Exploitation, and which does not have a demonstrable materially adverse effect on either of the Parties, shall be deemed necessary. Should the Parties fail to agree whether any Third Party license: (a) meets the criteria for being deemed necessary; or (b) is in fact necessary; such failure to agree shall be referred for resolution in accordance with Article 17.

(b) Maximum Amount of Royalty Reduction. In no event shall the royalties payable to Nanomerics under Section 7.9 be reduced by more than [**] in any Calendar Quarter as a result of the reductions set forth in this Section 7.10.

7.11 Royalty Term. Virpax’s obligation to pay royalties shall commence, on a country-by-country basis, with respect to each separate Licensed Product, on the date of First Commercial Sale of such Licensed Product in such country. The obligation shall expire, on a country-by-country basis, with respect to each separate Licensed Product, on the latest to occur of (a) the tenth (10th) anniversary of the First Commercial Sale of the first Licensed Product in such country; (b) the expiration date in such country of the last to expire of any Valid Claim; and, (c) the date upon which a Generic Product has been on the market in such country for a period of no fewer than [**] days.

7.12 Sales Subject to Royalties. Sales between Virpax and its Affiliates shall not be subject to royalties hereunder. Royalties shall be calculated on Virpax’s and its Affiliates’ and it and their Sub-licensees’ sale of the Licensed Products to a Third Party. Royalties shall be payable only once for any given batch of the Licensed Products. For purposes of determining [**], the Licensed Product shall be deemed to be sold upon Virpax, its Affiliates or Sub-licensees receipt of payment for the Licensed Product and a “[**]” shall not include, and no royalties shall be payable on, transfers by Virpax, its Affiliates or Sublicensees of free samples of Licensed Products or clinical trial materials containing Compound or transfers of Licensed Products to patients under any Virpax, Affiliate or Sub-licensee’s patient assistance programme or other transfers or dispositions for charitable, promotional, pre-clinical, clinical, manufacturing, testing or qualification, regulatory or governmental purposes.

7.13 Royalty Payments. The royalties shall be calculated quarterly as of the last day of March, June, September and December respectively, for the Calendar Quarter ending on that date. Virpax shall pay the royalties in conjunction with the delivery of a written report to Nanomerics within forty-five (45) days after the end of each Calendar Quarter that shows, with respect to each country and each Licensed Product, the [**] during such Calendar Quarter.

7.14 Currency; Mode of Payment.

(a) Currency. All payments required under this Agreement shall be made in U.S. Dollars. For the purpose of computing the Net Sales of Products sold in a currency other than U.S. Dollars, such currency shall be converted from local currency to U.S. Dollars by Virpax in accordance with the rates of exchange for the relevant month for converting such other currency into U.S. Dollars used by Virpax’s internal accounting systems, which are independently audited on an annual basis.

(b) Mode of Payment. All payments set forth in this Article 7 shall be remitted by wire transfer to the following bank account of Nanomerics or such other account as Nanomerics may designate in writing to Virpax:

BANK ACCOUNT

[**]

7.15 Records Retention; Audit.

(a) Until the sixth (6th) anniversary of January 31 of the Calendar Year in which a Product is sold, Virpax shall keep or cause to be kept accurate records or books of account in accordance with applicable generally accepted accounting principles showing the information that is necessary for the accurate determination of the royalties due hereunder with respect to the sale of such Product.

(b) Upon the written request of Nanomerics, Virpax shall permit a certified public accountant or a person possessing similar professional status and associated with an independent accounting firm acceptable to the Parties to inspect during regular business hours and no more than once a year and going back no more than three (3) years preceding the current year, all or any part of Virpax’s records and books necessary to check the accuracy of the royalties paid. The accounting firm shall enter into appropriate obligations with Virpax to treat all information it receives during its inspection in confidence, except for the purposes of presenting the findings of its audit. The accounting firm shall disclose to Nanomerics and Virpax only whether the royalty reports are correct and details concerning any discrepancies, but no other information shall be disclosed to Nanomerics. The charges of the accounting firm shall be paid by Nanomerics, except that if the royalties have been understated by [**] or more, the charges shall be paid by Virpax. Virpax shall make good any underpayment of royalties within forty-five (45) days of the disclosure of the accounting firm’s report.

8. Taxes

8.1 General The royalties, milestones and other amounts payable by Virpax to Nanomerics pursuant to this Agreement (“Payments”) shall not be reduced on account of any taxes unless required by Applicable Law. Nanomerics alone shall be responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be paid by Virpax) levied on account of, or measured in whole or in part by reference to, any Payments it receives hereunder. Virpax shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Nanomerics is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to Virpax or the appropriate governmental authority (with the assistance of Virpax 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 Virpax of its obligation to withhold tax, and Virpax shall apply the reduced rate of withholding, or dispense with withholding, as the case may be, provided that Virpax has received evidence, in a form satisfactory to Virpax, of Nanomerics’ delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least fifteen (15) days prior to the time that the Payments are due. If, in accordance with the foregoing, Virpax withholds any amount, it shall pay to Nanomerics the balance when due, make timely payment to the proper taxing authority of the withheld amount, and send to Nanomerics proof of such payment within sixty (60) days following that payment. For purposes of this Agreement, the stated amount of the Payments payable by Virpax shall include any sales tax that Nanomerics may be required to collect.

8.2 Indirect Taxes. All Payments are inclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any Payments, Virpax shall pay such Indirect Taxes at the applicable rate in respect of any such Payments following the receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by Nanomerics in respect of those Payments, such Indirect Taxes to be payable on the due date of the payment of the Payments to which such Indirect Taxes relate.

9. Confidentiality and Non-Disclosure

9.1 Virpax Information. Nanomerics recognises that by reason of, inter alia, Virpax’s status as an exclusive licensee or owner of the Virpax Results pursuant to Article 6, Virpax has an interest in Nanomerics’ retention in confidence of certain information, including proprietary information of Virpax, that is known to Nanomerics and without regard to whether such information was originally discovered, generated, or recorded by Virpax or Nanomerics. Accordingly, until the expiration of Virpax’s exclusive position with respect to a Product under Section 7.9, Nanomerics shall, and shall cause its Affiliates and their respective officers, directors, employees and agents to, keep completely confidential, and not publish or otherwise disclose, and not use directly or indirectly for any purpose (a) the Results and (b) any other Information, including any Confidential Information of Nanomerics or Virpax, relating to (i) any Licensed Product, including the Compound, any IP Protection Rights with respect thereto, and any Regulatory Documentation, including Health Registration Approvals, with respect thereto or (ii) the Exploitation of such Product, including development, sales or marketing plans therefor (collectively the “Virpax Information”); except to the extent (w) the Virpax Information is in the public domain through no fault of Nanomerics, its Affiliates or any of their respective officers, directors, employees and agents, (x) such disclosure or use would be expressly permitted under Section 9.3, or (y) such disclosure or use is otherwise expressly permitted by the terms of this Agreement. For clarification, the disclosure by Nanomerics to Virpax or by Virpax to Nanomerics of Virpax Information shall not cause such information to cease to be subject to the provisions of this Section 9.1. In the event this Agreement is terminated in its entirety by Virpax pursuant to Section 13.3 or by Nanomerics pursuant to Section 13.4, this Section 9.1 shall have no continuing force or effect and Virpax Information shall be deemed to be Confidential Information of Virpax or Nanomerics, as applicable, for purposes of the surviving provisions of this Agreement.

9.2 Confidentiality Generally. Subject to Section 9.1, at all times during the term of this Agreement and for a period of 5 years following termination or expiration hereof, each Party (the “Receiving Party”) shall, and shall cause its officers, directors, employees, agents, Affiliates and Sublicensees to, keep confidential and not publish or otherwise disclose and not use, directly or indirectly, for any purpose, any Confidential Information provided to it by the other Party (the “Disclosing Party”), except to the extent such disclosure or use is otherwise expressly permitted by the terms of this Agreement or is reasonably necessary for the performance of this Agreement. For the avoidance of doubt, the treatment of Confidential Information that is also Virpax Information is governed by the terms of Section 9.1, while the treatment of Confidential Information that is not also Virpax Information is governed by this Section 9.2.

9.3 Permitted Disclosures. Nanomerics may disclose Virpax Information and each Party may disclose Confidential Information (other than Virpax Information) to the extent that such disclosure is:

9.3.1. made in response to a valid order of a court of competent jurisdiction or other competent authority; provided, however, that the Receiving Party shall first have given notice to the Disclosing Party and given the Disclosing Party a reasonable opportunity to quash any such order or obtain a protective order requiring that the Confidential Information and documents that are the subject of such order be held in confidence by such court or authority or, if disclosed, be used only for the purpose for which the order was issued; and provided further that if such order is not quashed or a protective order is not obtained, the Confidential Information disclosed in response to such court or governmental order shall be limited to that information that is legally required to be disclosed in response to such court or governmental order;

9.3.3. made by a Party to a patent authority as may be necessary or useful for purposes of obtaining or enforcing a Patent (consistent with the terms and conditions of Article 10); provided, however, that reasonable measures shall be taken to assure confidential treatment of such information, to the extent such protection is available; or

9.3.4. otherwise required by law; provided, however, that if Nanomerics is required to disclose Virpax Information, or either Party is required to disclose Confidential Information of the other Party, the Party required to make the disclosure shall (a) provide to the other Party reasonable advance notice of and an opportunity to comment on any such required disclosure, (b) if requested by the other Party, seek confidential treatment with respect to any such disclosure to the extent available, and (c) use good faith efforts to incorporate the comments of the other Party in any such disclosure or request for confidential treatment; or

9.3.5. made by Virpax or its Affiliates to Third Parties as may be necessary or useful in connection with the Exploitation of the Compound or Licensed Products as contemplated by this Agreement, including subcontracting or sublicensing transactions in connection therewith.

Notwithstanding the foregoing, in the event that either Party is required by Applicable Law or the requirements of a national securities exchange or another similar regulatory body to disclose this Agreement, in whole or in part, the Parties shall reasonably agree on a redacted version of this Agreement as necessary to protect the Confidential Information of the Parties prior to making such disclosure.
