8.1.1Confidentiality

Materials constitute highly valuable assets of such other Party. SUBLICENSOR and ILDONG each agrees that, (a) subject to Section
8.1.2, during the Term and for an additional ten (10) years after termination or expiration of this Agreement it will not disclose,
and will cause its Affiliates, Sublicensees (with respect to ILDONG) and Distributors or Sublicensees (with respect to SUBLICENSOR)
not to disclose whether directly or indirectly, in any manner whatsoever, any Confidential Information or Proprietary Materials
of the other Party and (b) it will not use, and will cause its Affiliates, Sublicensees (with respect to ILDONG) and Distributors
or Sublicensees (with respect to SUBLICENSOR) not to use, any Confidential Information or Proprietary Materials of the other Party,
without the prior written consent of the Disclosing Party, except as expressly permitted hereunder.



8.1.2Limited
Disclosure. SUBLICENSOR and ILDONG each agrees that disclosure of its Confidential Information or any transfer of its
Proprietary Materials may be made by the other Party on a need-to-know basis to any employee, consultant or Affiliate of such
other Party or, to the extent the other Party is ILDONG, to any Third Party subcontractor engaged by ILDONG pursuant to Section
2.2, in each case solely to the extent reasonably necessary to enable such other Party to exercise its rights or to carry out
its responsibilities under this Agreement; provided, that, any such disclosure or transfer shall only be made to Persons who are
bound by written obligations comparable in scope to the obligations described in Section 8.1.3. SUBLICENSOR and ILDONG each further
agrees that the other Party may disclose its Confidential Information (a) on a need-to-know basis to such other Party’s
legal and financial advisors, (b) as reasonably necessary in connection with an actual or potential (i) permitted sublicense of
such Party’s rights hereunder, (ii) debt or equity financing of such other Party or (iii) acquisition, consolidation, share
exchange or other similar transaction involving such Party and any Third Party, (c) to the extent the other Party is ILDONG, to

other Party with reasonable advance notice of and an opportunity to comment on any such required disclosure and (ii) if requested
by the other Party, cooperate in all reasonable respects with the other Party’s efforts to obtain confidential treatment
or a protective order with respect to any such disclosure, at the other Party’s expense.

8.1.3Employees
and Consultants. SUBLICENSOR and ILDONG each hereby covenants and agrees that all of its employees and consultants, and
all of the employees and consultants of its Affiliates, who have access to Confidential Information or Proprietary Materials of
the other Party will, prior to having such access, be bound by written obligations to maintain such Confidential Information or
Proprietary Materials in confidence that are no less stringent than those confidentiality and non-use provisions contained in
this Agreement. Each Party agrees to use, and to cause its Affiliates to use, reasonable efforts to enforce such obligations and
to prohibit its employees and consultants from using such information except as expressly permitted hereunder. Each Party will
be liable to the other Party for any disclosure or misuse by its employees of Confidential Information or Proprietary Materials
of the other Party.



8.2Publicity.



Notwithstanding anything
to the contrary in Section 8.1, the Parties, upon the execution of this Agreement, shall jointly issue a press release
with respect to this Agreement to be reasonably agreed by the Parties in substantially the form attached hereto as Schedule
6, and either Party may make subsequent public disclosure of the contents of such press release without further approval of
the other Party. Subject to the foregoing, except as required by Applicable Laws (including those relating to disclosure of material
information to investors), neither Party shall issue a press or news release or make any similar public announcement (it being
understood that publication in scientific journals, presentation at scientific conferences and meetings and the like are intended
to be covered by Section 8.4 and not subject to this Section 8.2) related to the terms or existence of this Agreement or the conduct
of the Development Program or the Commercialization of Products without the prior written consent of the other Party; provided,
however, that either Party may make such a disclosure (a) to the extent required by Applicable Laws (including the requirements
of any nationally recognized securities exchange, quotation system or over-the-counter market on which such Party has its securities
listed or traded), or (b) to any investors, prospective investors, lenders and other potential financing sources who are obligated
to keep such information confidential. In the event that such disclosure is required as aforesaid, the disclosing Party shall
make reasonable efforts to provide the other Party with notice beforehand and to coordinate with the other Party with respect
to the wording and timing of any such disclosure. Once any press release or any other written statement is approved for disclosure
by both Parties, either Party may make subsequent public disclosure of the contents of such statement without the further approval
of the other Party.

8.3No
Use of Name.



Neither Party shall
use the name of the other Party in any Promotional Materials or advertising without the prior express written permission

9.4Patent
Coordinators.



Each Party shall,
by written notice to the other Party, appoint a patent coordinator reasonably acceptable to the other Party (each, a “Patent
Coordinator”) to serve as such Party’s primary liaison with the other Party on matters relating to the filing, prosecution,
maintenance and enforcement of Patent Rights. Each Party may replace its Patent Coordinator at any time by notice in writing to
the other Party. The initial Patent Coordinators shall be:

Inventorship.



The Parties hereby
agree to promptly notify to the other Party, through the Patent Coordinators, of the conception or reduction to practice of any
Program Technology or Joint-Improvement and to promptly execute any documents that may be necessary to perfect SUBLICENSOR’s
rights in and to such Program Technology or Joint-Improvement. The Patent Coordinators shall determine inventorship of Program
Technology or Joint-Improvement under U.S. patent law. In case of a dispute between the Patent Coordinators over inventorship
and, as a result, whether any particular Technology is SUBLICENSOR Technology or Joint Improvement, such dispute shall be resolved
according to U.S. patent law by patent counsel selected by the Patent Coordinators who (and whose firm) is not at the time of
the dispute, and was not at any time during the five (5) years prior to such dispute, performing services for either of the Parties.
Expenses of such patent counsel shall be shared equally by the Parties.

10.1.1SUBLICENSOR
Prosecution Rights. SUBLICENSOR shall have the sole right and responsibility to prepare and file applications
with respect to, and prosecute and maintain, at its sole discretion, and using patent counsel or agents of its choice, all Licensed
Patent Rights (including all Joint Patent Rights that are Licensed Patent Rights) throughout the Territory. ILDONG shall cooperate
with and assist SUBLICENSOR in all reasonable respects, in connection with SUBLICENSOR’s preparation, filing, prosecution
and maintenance of Licensed Patent Rights.



10.1.2ILDONG

to, and prosecute and maintain, at its sole cost, expense and discretion, and using patent counsel or agents of its choice, all
ILDONG Program Patent Rights throughout the Territory. SUBLICENSOR shall cooperate with and assist ILDONG in all reasonable respects,
in connection with ILDONG’s preparation, filing, prosecution and maintenance of ILDONG Program Patent Rights.



10.1.3Joint
Patent Rights. Subject to Section 10.1.1, within ten (10) Business Days after it is determined pursuant to Section 9.5
that any particular Program Technology is Joint Improvement, the Parties will determine which Party will undertake the prosecution
of such Joint Patent Rights based on the respective expertise of the Parties and the rights of the Parties under this Agreement.
If the Parties fail to agree within such ten (10) Business Day period, then prosecution of such Patent Rights shall be jointly
controlled by the Parties, using patent counsel agreed upon by the Patent Coordinators. All patent costs and expenses incurred
by a Party or jointly by the Parties in connection with the preparation, filing, prosecution and maintenance of Joint Patent Rights
in the Territory that cover any Product for use in the Field shall be shared equally by the Parties. Provided however that, if
a Party refuses, declines or fails to assume its obligations under this section 11.1.2, it shall advise the other Party and said
other Party shall have the right, at its own expense, to prepare, prosecute and maintain Patent Rights for Joint Improvements.
In such a case, upon request of the non-defaulting Party, the Party that refuses, declines or fails to file, prosecute or maintain
any such Patent Rights for Joint Improvements shall assign all its co-ownership rights to the other Party.



10.1.4Information
and Cooperation. The Parties hereby agree to cooperate with each other in connection with the filing, prosecution and
maintenance of Patent Rights under this Agreement, including through the prompt execution and delivery of documents and instruments
as may reasonably be required in connection therewith. Without limiting the foregoing, each Party responsible for the filing,
prosecution and/or maintenance of Patent Rights under Sections 10.1.1 and/or 10.1.2 above (a “Filing Party”)
shall (a) promptly provide the other Party with copies of all patent applications filed hereunder and other material submissions
and correspondence with applicable patent offices, in sufficient time to allow for review and comment by the other Party; (b)
