6. INTELLECTUAL PROPERTY RIGHTS. Any and all concepts, improvements, computer software, articles, pamphlets, brochures, marketing plans, or other information (collectively, “ Developments ”) which the Executive discovers, edits or develops during the Term of his/her employment, which relates to or is useful in connection with the business of Company, shall be deemed work for hire and shall be the sole and exclusive property of the Company.

7. NON-COMPETITION AND NON-SOLICITATION COVENANTS. As additional consideration to the Company for entering this Agreement, the Executive covenants that during the Restricted Period (as defined below), he shall not:

(a) compete against the Company, or any subsidiary or affiliate of the Company that is engaged in the Business (as defined below) (collectively, the “ Applicable Entities ”), either directly or indirectly, by taking employment, gratuitously assisting or serving as an independent contractor, consultant, partner, director or officer with a competitor of any of the Applicable Entities, or starting his own business that would compete directly or indirectly with any of the Applicable Entities, or have a material interest in any business, corporation, partnership, limited liability company or other business entity which competes directly or indirectly with any of the Applicable Entities. For purposes of this covenant, the term “the Business” shall mean developing, producing, designing, providing, soliciting orders for, selling, distributing, or marketing Company Products and Services in any state of the United States of America in which any of the Applicable Entities does business. For purposes hereof, “Company Products and Services” means any novel antibiotics used to treat infectious diseases, treatments for oral mucositis and proprietary probiotics specifically designed to enhance oral health for humans and pets, (i) which the Company currently anticipates developing, producing, designing, providing, marketing, distributing or selling, (ii) which the Company and any Applicable Entities develop, produce, design, provide, market or distribute while Executive is employed by the Company or is otherwise providing services to the Company, or (iii) that compete with any of the products and services of the Company and Applicable Entities referenced in (i) or (ii) above. For the purpose of defining and enforcing this covenant, the competitors of the Applicable Entities will be identified at

5

the time the Company seeks enforcement of this covenant. This determination shall be based on the then-existing market area of the Applicable Entities at the time enforcement of this covenant is sought. Notwithstanding the foregoing, investment by the Executive constituting less than five percent (5%) of the outstanding securities in a publicly-traded entity that may compete with the Applicable Entities shall not constitute a violation of this Section 7(a) as long as the Executive is not actively involved in such entity’s business.

(b) solicit or encourage, or attempt to solicit or encourage, any current customer or vendor of the Company or any of the Applicable Entities to do business with any person or entity in competition with any of the Applicable Entities or to reduce the amount of business which any such customer or vendor has customarily done or contemplates doing with any of the Applicable Entities, whether or not the relationship between any of the Applicable Entities and such customer or vendor was originally established in whole or in part through the Executive’s efforts; provided, however , that this Section 7(b) shall not be interpreted as preventing the Executive from conducting a business that does not consist of the Business conducted by the Applicable Entities with any customers or vendors of the Applicable Entities; or

(c) solicit or encourage, or attempt to solicit or encourage, any employee of the Company or any of the Applicable Entities, whether as an officer, employee, consultant, agent or independent contractor, or any person who was so employed or engaged at any time during the six (6) month period prior to the date of the Executive’s solicitation, to leave his or her employment with the Company or any of the Applicable Entities, to cease providing services to the Company or any of the Applicable Entities, or to accept employment with any other person or entity; provided however , that general solicitations not specifically targeted to employees of the Company or any of the Applicable Entities shall not constitute a breach of this Section 7(c) .

These covenants not to compete and not to solicit shall apply during the entire Term of the Executive’s employment with the Company and for a period of twelve (12) months following the date on which Executive is last employed by the Company (the “ Restricted Period ”). In the event of a breach by the Executive of any of the covenants in this Section 7 , the term of the Restricted Period will be extended by the period of the duration of such breach.

The Executive agrees that the relevant public policy and legal aspects of covenants not to compete have been discussed with him and that every effort has been made to limit the restrictions placed upon Executive to those that are reasonable and necessary to protect the legitimate interests of the Company, and the other Applicable Entities. The Executive acknowledges that, based upon his education, experience, and training, the non-compete and non-solicitation provisions of this Section 7 will not prevent the Executive from earning a livelihood and supporting the Executive and his family during the relevant time period.

The existence of a claim, charge, or cause of action by the Executive against the Company, or any other Applicable Entity shall not constitute a defense to the enforcement by the Company, or any other Applicable Entity of the foregoing restrictive covenants, but such claim, charge, or cause of action shall be litigated separately.

6

If any restriction set forth in this Section 7 is found by any court of competent jurisdiction to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, the court is hereby expressly authorized to modify this Agreement or to interpret this Agreement to extend only over the maximum period of time, range of activities, or geographic areas as to which it may be enforceable.

In exchange for the consideration set forth in Section 9 of the Executive Employment Agreement dated as of June 6, 2016 (the “Employment Agreement”) between Alan Joslyn (“Executive”) and Oragenics, Inc., (the “Company”), the Executive, for himself and his heirs, assigns, executors and administrators, shall waive and release the Company, and its successors and assigns, as well as any subsidiary of the Company, and its respective officers, directors, agents, shareholders and employees (the “Company Released Parties”), from any and all Claims and Controversies as defined herein, with the exception of claims arising directly out of the Company’s obligations under Section 9, of the Employment Agreement.

The Executive understands that the Executive is releasing Claims and Controversies of which the Executive may not be aware. This is the Executive’s knowing and voluntary intent, even though the Executive recognizes that someday the Executive might learn that some or all of the facts that the Executive currently believes to be true are untrue and even though the Executive might then regret having signed this Release. Nevertheless, the Executive is assuming that risk and the Executive agrees that this Release shall remain effective in all respects in any such case. It is further understood and agreed that the Executive is waiving all rights under any statute or common law principle which otherwise limits application of a general release to claims which the releasing party does not know or suspect to exist in his favor at the time of signing the release which, if known by him, would have materially affected his settlement with the party being released and the Executive understands the significance of doing so.

Neither the Executive nor his heirs, agents, representatives or attorneys have filed or caused to be filed any lawsuit, with respect to any Claims and Controversies that the Executive is releasing in this Agreement. Nothing in this Release is intended to limit in any way the Executive’s right or ability to file a charge or claim of discrimination with the U.S. Equal Employment Opportunity Commission (“EEOC”) or comparable state or local agencies. These agencies have the authority to carry out their statutory duties by investigating the charge, issuing a determination, filing a lawsuit in federal or state court in their own name or taking any other action authorized under these statutes. The Executive retains the right to participate in any such action. The Executive retains the right to communicate with the EEOC and comparable state or local agencies and such communication can be initiated by him or in response to the government and is not limited by any non-disparagement or confidentiality obligation under this Release. The Executive hereby waives and releases his right to recover money or other relief in any action that might be brought on his behalf by any other person or entity including, but not limited to, the State of Florida, EEOC, the Department of Labor or any other federal, state or local agency or department.

The Executive has twenty-one (21) calendar days from the date the original Release was given to him,                     , 20    , to consider this Release before signing it. The twenty-one (21) day period expires on                     , 20    . The Executive may use as much or as little of this twenty-one (21) day period as he wishes before signing. Any change in this Release, material or

A-2

otherwise, does not restart the 21 day period. If the Executive does not sign and return this Release within this twenty-one (21) day period, it will not become effective or enforceable and Executive will not receive all of the benefits described in this Release.

This Release may be revoked by the Executive for a period of seven (7) calendar days following the execution of the Release (the “Revocation Period”). No payments shall be made and the Release shall not become effective or enforceable until the Revocation Period has expired. Any such revocation must be communicated in writing to the Company. Any such revocation must be received by the Company no later than the next business day after the Revocation Period expires.

The Company has advised the Executive to consult with an attorney prior to executing the Release. The Executive acknowledges and represents that he (a) has fully and carefully read this Release prior to signing it, (b) has been, or has had the opportunity to be, advised by independent legal counsel of his own choice as to the legal effect and meaning of each of the terms and conditions of this Release, and (c) is signing and entering into this Release as a free and voluntary act without duress or undue pressure or influence of any kind or nature whatsoever and has not relied on any promises, representations or warranties regarding the subject matter hereof other than as set forth in this Release.
