| | A. |  | The Shareholder is the holder of certain patents, provisional
patents and patent applications listed on Schedule A (Patents) relating to certain pharmaceutical and/or homeopathic
compounds and dosing and delivery systems intended for use by humans (the Intellectual Property); and
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | B. |  | The Shareholder, in consideration of the issuance to it of shares
in the Company, desires to grant to the Company an exclusive license to the Intellectual Property within the Field of Use, as
defined on Schedule A, subject to the terms and conditions of this Agreement.
| | -- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

NOW, THEREFORE,
in consideration of the foregoing Recitals and the mutual promises and agreements contained herein, the parties agree as follows:

1.   License
Grant.   The Shareholder hereby grants to the Company an exclusive, royalty-free, perpetual, worldwide right
and license to the Intellectual Property for the Field of Use (the License), with the right to sublicense, to make,
have made, use, sell or otherwise dispose of products covered by the License (Products). The License covers Patents
and Patent renewals, reissues, divisions, substitutions, continuations, continuations-in-part, extensions or improvements. The
License also covers any and all patent applications first filed with the United States Patent and Trademark Office (USPTO) or any
appropriate international organization on or before November 9, 2009. For purposes of understanding and interpreting this
Agreement, the future patent applications and filings shall be considered as Intellectual Property and any resulting
patent a Patent covered hereby, along with any subsequent renewals, reissues, divisions, substitutions, continuations,
continuations-in-part, extensions or improvements of such future filed patents. The License granted hereby precludes license of
the Intellectual Property for the Field of Use by the Shareholder to any other person or commercial exploitation of the
Intellectual Property in the Field of Use by the Shareholder. The Shareholder retains unrestricted rights to the Intellectual
Property outside of the Field of Use and the right to use the Intellectual Property within the Field of Use for its own operations
(e.g. for research and development). This License may be assigned, transferred or sold by the Company only with the written, prior
consent of the Shareholder. This License, the Patents, and the Intellectual Property are freely transferable by the Shareholder.

2.   Development
and Commercialization.   The Company shall be solely responsible for taking the steps necessary or proper to
develop and commercialize the Intellectual Property in the Field of Use and agrees to use its best efforts to do so as quickly as
possible.

3.   Improvements.   All
improvements to the Intellectual Property (Improvements) shall be the sole property of the Shareholder, regardless of
the identity of the maker of the Improvements. However, the Improvements pertaining to the Field of Use are hereby licensed to the
Company as a part of the License.

4.   Acknowledgments
and Covenants.   The Company acknowledges that the Shareholder is the sole and exclusive owner of the
Intellectual Property and that nothing in this Agreement shall be deemed to convey any rights or proprietary interest in same to
the Company, other than the specific License granted hereunder. The Company and its officers, agents, servants, employees,
attorneys, subsidiaries, successors, assigns and any person or entity in active concert or participation with the Company agrees
not to challenge or cause to be challenged, directly or indirectly, the ownership, proper naming of inventors, validity or
enforceability of any Patent rights of the Shareholder.

5.   Infringement.

| | (a)   The
Company shall give notice to the Shareholder of any discovered third party infringement of the Patents in the Field of Use. In the
event that the Company does not take appropriate action to stop or prevent such infringement within sixty (60) days after giving
such notice and diligently pursue such action, the Shareholder has the right to take appropriate action to stop and prevent the
infringement, including the right to file suit.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b)   In
the event that the Shareholder files suit to stop infringement or defends any action against the validity of any Patents, the
Company shall indemnify and hold the Shareholder harmless against all liability, expense and costs, including attorneys fees
incurred as a result of any such suit.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c)   The
parties hereby agree to cooperate with each other in the prosecution of any such legal actions or settlement actions undertaken
under this section and each will provide to the other all pertinent data in its possession which may be helpful in the prosecution
of such actions; provided, however, that the party in control of such action shall reimburse the other party for any and all costs
and expenses in providing data and other information necessary to the conduct of the action.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (d)   The
party having filed such action shall be in control of such action and shall have the right to dispose of such action in whatever
reasonable manner it determines to be the best interest of parties hereto, except that any settlement which affects or admits
issues of a valid claim to any Patent shall require the advance written approval of the Shareholder.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

6.   Term
of Agreement and Termination.   This Agreement shall remain in full force and effect until the expiration of
the last to expire of the Patents, subject to earlier termination in accordance with the provisions of this Agreement.

authority of the Company or, as the case may be, its assigns. The Company shall provide notice to the Shareholder of its intention
to file a voluntary petition in bankruptcy or of another partys intention to file an involuntary petition in bankruptcy for
the Company. The Companys failure to provide such notice to the Shareholder shall be deemed a material pre-petition,
incurable breach of this Agreement.
