		3.	Grant of Rights

 

License Grants to Virpax.
Subject to the terms and conditions of this Agreement, as from the New Effective Date Nanomerics hereby grants to Virpax an exclusive
(including with regard to Nanomerics and its Affiliates) right and license in the Territory, with the right to grant sublicenses pursuant
to Section 3.2, under Nanomerics’ and its Affiliates’ rights, titles, and interests in and to the Licensed Patents for the
Compound, the Licensed Know-How, the Licensed Improvements to the Compound, and Nanomerics Results to Exploit the Licensed Products solely
in the Field.

 

	3.1	Sublicenses. Virpax shall have the right to grant sublicenses,
through multiple tiers of sublicenses, under the licenses granted in Section 3.1, to its Affiliates and to any other Person provided
that:

 

		3.1.1.	the sub-license is in writing and contains like obligations
and undertakings by the sub-licensee as are contained in this Agreement including in particular (but not limited to) clause 9 (confidentiality),
and Virpax ensures that all sub-licensees duly observe and perform the same; and;

 

		3.1.2.	Virpax shall remain primarily 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;

 

		3.1.3.	the sub-license will terminate automatically on the expiration
or termination of this Agreement for any reason;

 

		3.1.4.	Virpax shall notify Nanomerics in writing of any sub-license

sublicenses comply with all terms and conditions of this Agreement.

 

    13

     

    

 

Where Virpax grants a sublicense
to a Person that is not an Affiliate of Virpax, and such Person is not a Distributor, such Person shall be a “Sublicensee”
for purposes of this Agreement.

 

Virpax shall have the right, in its sole discretion,
to appoint its Affiliates, and Virpax and its Affiliates shall have the right, in their sole discretion, to appoint any other Persons,
in the Territory or in any country of the Territory, to distribute, market and sell Licensed Product (with or without packaging rights),
in circumstances where the Person purchases on its own account its requirements of Licensed Product from Virpax or its Affiliates for
on- sale to such Person’s customers. Such Person shall be identifiable in the pharmaceutical industry, and would usually be designated
as a wholesaler or a distributor, and such Person shall not otherwise make any royalty or other payment to Virpax with respect to its
sale of Licensed Products. Where Virpax or its Affiliates appoints such a Person and such Person is not an Affiliate of Virpax, that Person
shall be a “Distributor” for purposes of this Agreement.

 

	3.2	Covenants

 

		3.2.1.	Publication. To the extent Nanomerics and its Affiliates conduct
research and development activities with respect to Licensed Products and consistent with the exclusive license grants to Virpax under
Section 3.1, Nanomerics agrees that neither it nor its Affiliates will publish or present any material with respect to such activities
without the prior written consent of Virpax in each case, which consent will not be unreasonably withheld or delayed. For the avoidance
of doubt, the Parties acknowledge that University College London (“UCL”) retains a research license with respect to patents
underlying the Compound which allows UCL’s employees and students to conduct bona fide academic research or teaching without infringing
such patents, and that UCL its employees or students together with its research collaborators may make publications or presentations
complying with such research license, and may make related patent applications, over which Nanomerics has no control.

 

		3.2.2.	Non-Compete. During the Term, Nanomerics covenants that it and its Affiliates shall not alone or with any Third Party (including
through licensing or sublicensing any Third Party), directly or indirectly, develop, Manufacture, or commercialize in the Territory any
product, (other than a Licensed Product in accordance with this Agreement) comprising, containing or incorporating the Compound as the
sole active ingredient for any use in prevention or reduction of the risk of any viral infection.

 

		3.2.3.	The Parties acknowledge that all restrictions contained in Section 3.2.2 are reasonable, valid and necessary for the adequate protection
of the Licensed Product business and that Virpax would not have entered into this Agreement without the protection afforded it by Section
3.2.2. The Parties also acknowledge that Nanomerics’ entire business is based on development of the Compound for various uses, including
its combination with at least one other pharmaceutical compound or active ingredient to generate new or improved medicinal products, and
therefore nothing in these restrictions, nor in any other provision of this Agreement shall act as or be construed as any restriction
on Nanomerics’ right to, either itself or through licensees, Exploit and/or otherwise research, develop and commercialize products
containing the Compound, provided that such products also contain at least one other pharmaceutical compound or active ingredient or are
for any purpose outside the Field.

 

    14

     

    

 

		3.2.4.	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.

 

	3.3	Exclusivity Term. Virpax’s exclusive position granted
by Section 3.1 shall expire with respect to each separate Licensed Product, on a country-by-country basis, on the date when Virpax’s
obligation to pay Profit Share Payments or royalties with respect to such Licensed Product pursuant to Section 7.9(a) or Section 7.9(b)
(as applicable) expires. Upon expiry of Virpax’s exclusive position with respect to a Licensed Product in a country, Virpax’s
license with respect to such Licensed Product in such country shall become non-exclusive, fully paid-up, perpetual and irrevocable and
the Net Sales of such Licensed Product in such country shall be excluded from all Net Sales calculations in Article 7 and Schedule 7
(including the calculation of royalties, Profit Share Payments, thresholds and ceilings). 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 New 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.

 

	4.2	Diligence Obligations. Virpax shall (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 Exploit, more than one Licensed Product in any Major Market. In the event that Virpax, in consultation
with Nanomerics, decides to discontinue the development or Exploitation 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 eighteen (18) months of the New Effective
Date.

 

    15

     

    

 

	4.3	Reporting Virpax shall provide Nanomerics (through the 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 New Effective Date,
Virpax shall promptly commence 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 at Virpax’ expense.

 

	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.

 

    16

     

    

 

	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.

 

	5.	Management of the Program

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.

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.

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.

in Section 3.3.1 and are 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,

	6.5	[Intentionally Omitted]

 

	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, Profit Share Payments 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.

 

	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 (the “Phase II FIH Date”), Virpax
shall pay to Nanomerics the following one-time payment based on the value attributed to Virpax as a result of the Change of Control within
thirty (30) days following the closing date of the Change of Control:

 

    18

     

    

 

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

 

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

 

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

 

	7.3	Program Milestones. The Parties acknowledge that, pursuant to the Prior Agreement, a payment of U.S.$ 1,000,000 was made by
Virpax to Nanomerics within thirty (30) days following the Funding Completion Date (as defined in the Prior Agreement). 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. $ 1,500,000 within five (5) days after the New Effective Date;

 

		(b)	a payment of U.S. [**] within thirty (30) days following the Phase II FIH Date;

 

		(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;

 

		(d)	a payment of U.S.[**] within thirty (30) days following first receipt by Virpax of Health Registration Approval for a Licensed Product
in any member state of the European Union;

 

		(e)	a payment of U.S.[**] within thirty (30) days following first receipt by Virpax of Health Registration Approval for a Licensed Product
in any jurisdiction the Asia/Pacific Region; and

 

		(f)	a payment of U.S.[**] within thirty (30) days following first receipt by Virpax of Health Registration Approval for a Licensed Product
in any jurisdiction in the SA/ME Region.

 

	7.4	[Intentionally Omitted].

 

	7.5	[Intentionally Omitted].

 

	7.6	Commercial Milestones. Only if the Profit Share Trigger has not occurred for any Licensed Product, upon achievement of each
milestone specified on Schedule 7 (each a “Commercial Milestone”), Virpax shall, within the timescale specified
on Schedule 7, make the corresponding non-refundable payment to Nanomerics, as set forth on Schedule 7. For clarity, Virpax
shall have no obligation to pay any of the Commercial Milestones in any jurisdiction if the Profit Share Trigger has occurred for any
Licensed Product .

 

	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 [**] of such Third Party Sublicense Payment.

 

    19

     

    

 

	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	Profit Share Payments and Royalties.

 

		(a)	Profit Share Payments. Where the Profit Share Trigger
has occurred for a Licensed Product, Virpax shall make quarterly payments to Nanomerics in accordance with Section 7.13 equal to the
Applicable Profit Share Percentage of [**] (the “Profit Share Payments”) for such Licensed Product. To the extent
the calculation of [**] for a Calendar Quarter results in a negative amount, Virpax may carry over and deduct such amount in calculating
Licensed Product Net Operating Profit for future Calendar Quarters. For any subsequent Calendar Quarter after the payment of a Profit
Share Payment, Virpax may adjust and re-calculate the Profit Share Payments for prior Calendar Quarters due to additional events affecting
the calculation of [**], such as returns, chargebacks, fees assessed, liabilities associated with a Licensed Product, or other deductions
not previously captured.

 

		(b)	Royalties. If the Profit Share Trigger has not occurred
for a Licensed Product, Virpax shall, subject to Section 7.10, pay Nanomerics a royalty of [**]percent ([**]%) of the Annual Net Sales
of such Licensed Products in the Territory throughout the Royalty Term.

 

		(c)	For clarity: (i) whether or not a Profit Share Trigger has occurred
with respect to a given Licensed Product is based solely on the determination by the FDA whether or not such Licensed Product may be
marketed as an OTC Product in the United States, (ii) if a Profit Share Trigger has occurred with respect to a Licensed Product, then
Profit Share Payments (as opposed to royalties) will be payable with respect to worldwide sales of such Licensed Product, even in jurisdictions
outside the United States where such Licensed Product is marketed as an Rx Product and (iii) similarly, if a Profit Share Trigger has
not occurred with respect to a Licensed Product, then royalties (as opposed to Profit Share Payments) will be payable with respect to
worldwide sales of such Licensed Product, even in jurisdictions outside the United States where such Licensed Product is marketed as
an OTC Product. In no event will Virpax be required to pay Profit Share Payments and royalties with respect to the same sale of Licensed
Product.

 

    20

     

    

 

	7.10	Reduction of Royalty.

 

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 Section 7.9(b) 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 Section 7.9(b) 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,

		8.	Taxes

 

	8.1	General The royalties, milestones, Profit Share Payments 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

on the due date of the payment of the Payments to which such Indirect Taxes relate.

 

    23

     

    

  

	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.

 

    24

     

    

 

	9.2	Confidentiality Generally. Subject to Section 9.1, at all times during the term of this Agreement

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

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;

		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

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.

 

    25

     

    

 

	9.4	Exclusions. Notwithstanding the foregoing, Confidential Information shall not include any information

or its Affiliates’ possession prior to disclosure by the Disclosing Party;

 

		9.4.3.	is subsequently received by the Receiving Party or its Affiliates from a Third Party or a Sublicensee
who is not bound by any obligation of confidentiality with respect to said information;

 

		9.4.4.	is generally made available to Third Parties by the Disclosing Party without restriction on disclosure;
or

Party’s Confidential Information.

 

	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.

  

		9.6.2.	Notwithstanding the foregoing, Virpax, its Affiliates and Sublicensees shall have the right to use the
name of Nanomerics and its Affiliates to the extent necessary or useful in connection with the Exploitation of the Compound and Products
as contemplated by this Agreement, including subcontracting and sublicensing transactions in connection therewith.

 

		9.6.3.	Neither Party shall issue any press release or make any other public announcement or statement concerning
this Agreement or the transactions covered by it without the prior written approval of the other Party, except that each Party (after
consultation with counsel) may make such announcements and disclosures, if any, as may be required by Applicable Law or the requirements
of a national securities exchange or another similar regulatory body, or in connection with a public offering of securities or any filing
with the U.S. Securities and Exchange Commission or a foreign equivalent.

such action, to obtain prosecute or maintain any Licensed Patent in any country of the Territory, 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

Patent or other intellectual property rights of any Person (an “Infringement Suit”), the Party first becoming aware
of such Infringement Suit shall promptly give written notice to the other Party. Nanomerics shall have the first right, but not the obligation,
through counsel of its choosing, to assume direction and control of the defence of claims arising therefrom (including the right to settle
such claims in its sole discretion). Without limiting Nanomerics obligation to Virpax as contemplated in Section 12.2, should Nanomerics
decline to take any action, it shall immediately notify Virpax, and Virpax shall be entitled, in its sole discretion, through counsel
of its choosing to assume direction and control of the defence of claims arising therefrom (including the right to settle such claims
in its sole discretion).

when Asia/Pacific Region Annual Net Sales exceeds [**];

 

		(b)	a payment of [**]within thirty (30) days of the end of the Calendar Year in which occurs the first occasion

Sales exceed [**] and in all previous Calendar Years, North America Annual Net Sales had been less

Annual Net Sales, then in Calendar Year A, all three Commercial Milestones for North America Annual Net Sales pursuant to Section 1(a),
1(b) and 1(c) above totaling [**]would be payable, with North America Annual Net Sales of [**]all
having been first exceeded in that Calendar Year A.
