3.1.1. Exploit the Licensed Products comprised partly of the Device, in the Device Field; and,

3.1.2. Exploit the Compound, the Technology and any Licensed Products not comprising the Device, and any Improvements thereto for all purposes in the Field.

3.2.2. Virpax shall remain responsible for all acts and omissions of such sub-licensees as though they were by Virpax and shall indemnify, keep indemnified and hold harmless Nanomerics from and against all such costs, expenses and liabilities, which Nanomerics incurs or suffers as a result of the default or negligence of any sub-licensee;

The Parties acknowledge that all restrictions contained in this Section 3.4.2 are reasonable, valid and necessary for the adequate protection of the Licenced Product business and that Virpax would not have entered into this Agreement without the protection afforded it by this Section 3.4.2.

3.3.3. No Encumbrance. Nanomerics shall not assign, transfer, convey or otherwise encumber its rights to the Licensed Patents, Licensed Know-How, Licensed Improvements or Health Registration Approvals in any way that is detrimentally inconsistent with the exclusive licenses or other rights granted to Virpax under this Agreement.

3.4 Exclusivity Term. Virpax’s exclusive position granted by Section 3.1 shall expire with respect to each separate Licenced Product, on a country-by-country basis, on the date when Virpax’s obligation to pay royalties with respect to such Licenced Product pursuant to Section 7.9 expires. Upon expiry of Virpax’s exclusive position with respect to a Licenced Product in a country, Virpax’s licence with respect to such Licenced Product in such country shall become non-exclusive, fully paid-up, perpetual and irrevocable and the Net Sales of such Licenced Product in such country shall be excluded from all Net Sales calculations in Article 7 (including the calculation of royalties, thresholds and ceilings). In such circumstances (but not in any circumstance where this Agreement has been terminated by Nanomercis for breach by Virpax, or by Vipax at will) Virpax, its Affiliates and Sub- licensees shall be allowed to continue Exploiting such Licenced Product and using all Licenced 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, Regulatory Documentation, Licenced Know-How, Licensed Improvements and any other Information claimed or covered by any Licenced Patent or otherwise relating, directly or substantially, to the Compound or Licenced Products, as soon as reasonably practical after the Effective Date 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, Licenced Know-How, Licensed Improvement or other Information.

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 Licenced Product and to conduct all development necessary to obtain Health Registration Approvals for a Licenced Product in each of the Major Markets, and (ii) use Commercially Reasonable Efforts to commercialise such Licenced Product in each of the Major Markets in the Territory, provided, however, that such obligations are expressly conditioned upon Nanomerics substantially performing its obligations hereunder to the extent any non-performance hinders any Exploitation by Virpax, and such obligations of Virpax shall be delayed or suspended as long as any such condition exists. For the avoidance of doubt, Virpax shall not be obligated to obtain Health Registration Approval for, or commercialise, more than one Licenced Product in any Major Market. In the event that Virpax decides to discontinue the development or commercialisation of a Licenced Product in favour of another Licenced Product, its obligations under this Section 4.2 shall cease with respect to such initial Licenced Product in favour of such other Licenced 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 Licenced 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 Licensed Product 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 Licenced 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.

Following the Effective Date, the Parties shall promptly commence the Program, provided, however, that neither party shall be obligated to initiate any activities under the Clinical Development Plan until the Funding has been fully received by Virpax. Each Party shall assume responsibility for its own costs and expenses for the Program or as otherwise might be agreed in writing.

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.

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 unattainable 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 dispute resolution that is unattainable 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.

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 expiration of the Collaboration Term the JRC shall be dissolved and Nanomerics shall provide Virpax with consultation services as Virpax may reasonably request during the reminder 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.

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. Each Party shall promptly disclose to the other in writing the development, making, conception or reduction to practice of any Results.

6.2 Virpax hereby grants to Nanomerics the non-exclusive, perpetual, royalty free right and licence to use those Virpax Results referable specifically to the Products for regulatory purposes and uses with respect only to products (other than the Products) which comply with Nanomerics’ non-compete obligations as specified in clause 3.2.2.

6.3 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. Assignment and transfer of all such Results shall occur instantly and automatically and shall not require any further deeds or documents to be exchanged between the Parties.

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.

7.2 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:

7.2.1. a payment of U.S.$ [**] within [**] days following the Funding Completion Date;

7.2.2. a payment of U.S.$ [**] within [**] days following completion of the first Phase II Clinical Trial with respect to a Licensed Product in the Territory; and

7.2.3. a payment of U.S.$ [**] within [**] days following first receipt by Virpax of an NDA approval for a Licensed Product in the USA.

7.3 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:

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

Page 15 of 43

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

7.3.2. a payment of US$ [**] within [**] days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales exceeds US$ one hundred million (100,000,000);

7.3.3. a payment of US$ [**] within [**] days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales exceeds US$ three hundred million (300,000,000);

7.3.4. a payment of US$ [**] within [**] days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales exceeds US$ five hundred million (500,000,000); and

7.3.5. a payment of US$ [**] within [**] days of the end of the Calendar Year in which occurs the first occasion when the Annual Net Sales exceeds US$ eight hundred million (800,000,000).

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 clauses 7.3.1, 7.3.2 and 7.3.3 totalling US$ [**] would be payable, with Annual Net Sales of US$ fifty million (50,000,000), US$ one hundred million (100,000,000) and US$ three hundred million (300,000,000) all having been first exceeded in that Calendar Year A.

7.4 Upfront and Milestone Payments by Sublicensee. Within thirty (30) days of receipt by Virpax of:

7.4.1. any Third Party Sublicense Payment, Virpax shall pay to Nanomerics a non- refundable amount, equal to [**] of the net receipts of any such payment excluding any Indirect Taxes;

7.4.2. any other consideration from a Third Party which is not referable to any services to be provided by Virpax, and which has been made specifically because of Virpax’s rights to the Licensed Patents and Licensed Products, but not with the predominant purpose of being used in the development of Licensed Products (for example, but not by way of limitation, any consideration where a consequence of the payment of which includes any preferential treatment of a Third Party with respect to Licensed Products, whether by way of price, exclusivity or otherwise), Virpax shall pay to Nanomerics a non-refundable amount equal to [**] of the value of any such consideration (excluding any Indirect Taxes).

Page 16 of 43

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

7.5 Each of the Program Milestones and Commercial Milestones set forth above 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.

7.6 Royalties. In addition to the foregoing payments, Virpax shall, subject to Sections 7.7 and 7.8, pay Nanomerics a royalty of [**] of the Annual Net Sales of Licensed Product in the Territory.

7.7 Combination Products. With respect to Combination Products, the Annual Net Sales used for the calculation of the royalties under Section 7.6 shall be determined as follows:

       A       A + B x Net Sales of the Combination Product, where:

A = standard sales price of the Product (adjusted pro rata for quantity), containing the Compound as the sole active ingredient as the Combination Product in question, in the given country.

B = standard sales price of the ready-for-sale form of a product (adjusted pro rata for quantity) containing the other therapeutically active ingredient(s) that is contained in the Combination Product in question, in the given country.

7.8 Reduction of Royalty.

7.8.1. Royalty Stacking. If, during the Term, Virpax enters into an agreement with a Third Party in order to obtain a licence under a patent right of a Third Party that is necessary or desirable 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 7.6 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 7.8       by more than [**] of the royalties under Article 7.6 otherwise due to Nanomerics in a particular Calendar Quarter. For the purposes of this Section 7.8.1, the Parties’ respective alliance managers shall endeavour to agree in good faith whether a Third Party licence is “necessary” or “desirable”. A Third Party licence 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 or desirable. Should the Parties fail to agree whether any Third Party licence: (a) meets the criteria for being deemed necessary or desirable; or (b) is in fact necessary or desirable; such failure to agree shall be referred for resolution in accordance with Article 17.

7.8.2. Maximum Amount of Royalty Reduction. In no event shall the royalties payable to Nanomerics under Article 7 be reduced by more than [**] in any Calendar Quarter as a result of the reductions set forth in this Section 7.8.

7.9 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) [**] 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 ninety (90) days.

7.10 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 Net Sales, 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 “sale” 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.

7.11 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 sales volume and Net Sales during such Calendar Quarter.

7.12 Currency; Mode of Payment.

7.12.1. 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.

7.13 Records Retention; Audit.

7.13.1. 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.

7.13.2. 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 more than [**], 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.

9.3.1. 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;

9.3.2. made by or on behalf of by Virpax, its Affiliates or sublicensees to a Health Authority as may be necessary or useful in connection with any filing, application or request for a Health Registration Approval; provided, however, that reasonable measures shall be taken to assure confidential treatment of such information, to the extent such protection is available;

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

9.5 Publications and Presentations. The Parties acknowledge that scientific publications must be strictly monitored to prevent any adverse effect from premature publication of results of the research and development activities hereunder. Accordingly, no fewer than thirty days prior to the expected date of publication or presentation, Nanomerics shall provide to Virpax, any material related to the Program, the Virpax Results or the Exploitation of Licensed Products that Nanomerics wishes to publish or present, and Nanomerics shall not publish, present or otherwise disclose any such material without the prior written consent of Virpax, which shall not be unreasonably withheld nor delayed. Each Party’s contribution to such Results shall be duly recognised in such publications or presentations.

9.6 Use of Name/Publicity.

9.6.1. Neither Party shall mention or otherwise use the name, insignia, symbol, trademark, trade name or logotype of the other Party or its Affiliates in any publication, press release, promotional material or other form of publicity without the prior written consent of the other Party. The restrictions imposed by this Section 9.6.1 shall not prohibit either Party from making any disclosure identifying the other Party that is required by Applicable Law or the requirements of a national securities exchange or another similar regulatory body, provided that any such disclosure shall be governed by this Article 9. Further, the restrictions imposed on each Party under this Section 9.6.1 are not intended, and shall not be construed, to prohibit a Party from identifying the other Party in its internal business communications, provided that any Confidential Information or Virpax Information in such communications remains subject to this Article 9.

If Nanomerics declines, or otherwise fails to diligently pursue such action, to obtain prosecute or maintain any Licensed Patent in any country, Virpax shall have the right, providing that to do so would not result in a demonstrably material adverse effect on the Exploitation of Licensed Products, but not the obligation, to take such action through counsel of its choosing, with respect to such Licensed Patent in such country. The reasonable cost and expense of such action shall be borne equally by the Parties, and Nanomerics’ contribution to such cost and expense shall be deducted by Virpax from any Royalties payable with respect to such Licensed Patent in such country.

10.4 Virpax shall have the right to request that Nanomerics obtain, prosecute and maintain a Licensed Patent in a particular country. If Nanomerics declines, or otherwise fails, to initiate any such requested action with respect to a Licensed Patent within sixty (60) days (or, if after initiating any requested action, Nanomerics at any time thereafter fails to diligently pursue such action), Virpax shall have the right, providing that to do so would not result in a demonstrably material adverse effect on the Exploitation of Licensed Products, but not the obligation, to take such action, through counsel of its choosing, with respect to such Licensed Patent.

SCHEDULE 2: THE DEVICE

The device provides an apparatus for the nasal delivery of a medicament, comprising a sealed container containing the medicament and a gaseous propellant for the medicament (‘Capsule’) and a delivery device, in use, holds the sealed flexible container; and when actuated in use, causes the sealed flexible container to be ruptured and the propellant to expel the medicament from the container, thereby delivering the medicament.

Specifically, the capsule comprises a container for a fluid, a chamber for containing a particulate, and a pair of channels which run between the container and the chamber to provide fluidic communication between the container and the chamber.

An advantage of the dispenser is that it may be used and will operate in any orientation. Thus it may be used in upright, inverted or laid-down fashion. Another advantage is that it solves the problem of deaggregating and/or fluidising particulates using relatively uncomplicated and potentially inexpensive technology.

SCHEDULE 3: FUNDING PLAN

NCATS/BrIDGs

The National Center for Advancing Translational Sciences (NCATS), is one of the 27 Institutes and Centers (ICs) at the National Institutes of Health (NIH), and is transforming translational science to get more treatments to more patients more quickly. NCATS relies on the data, new technologies and teamwork to develop, demonstrate and disseminate innovations that reduce, remove or bypass costly and time-consuming bottlenecks in translational research. NCATS focuses on what is common across diseases and the translational process. The Center conducts and supports research on both the scientific and operational aspects of translation to lead to more predictive and successful development of new medical interventions, such as drugs, diagnostics, and medical devices, for all human diseases. By emphasizing collaboration, innovation, deliverables and team science, the Center serves as a catalyst to enable others in the translational research ecosystem to work more effectively.

Translation is the process of turning observations in the laboratory, clinic and community into interventions that improve the health of individuals and the public — from diagnostics and therapeutics to medical procedures and behavioral changes. Translational science is the field of investigation focused on understanding the scientific and operational principles underlying each step of the translational process.

NCATS studies translation on a system-wide level as a scientific and operational problem.

The Bridging Interventional Development Gaps (BrIDGs) program enables research collaborations to advance candidate therapeutics for both common and rare diseases into clinical testing. Investigators do not receive grant funds through this program. Instead, selected researchers partner with NCATS experts to generate pre-clinical data and clinical-grade material through government contracts for use in Investigational New Drug (IND) applications to a regulatory authority such as the Food and Drug Administration (FDA). In general, BrIDGs provides synthesis, formulation, pharmacokinetic and toxicology expertise and resources to its collaborators.

NIH contractors conduct pre-clinical studies under the direction of NCATS staff. NCATS, along with any co-funding NIH Institutes and Centers, supports contract costs. The decision to collaborate on a proposed project is based on an internal assessment of scientific merit, programmatic fit and the availability of NIH funds.
