ADVISORY AGREEMENT

The Advisor Agreement (“Agreement”) effective as of 27 October 2021 (the “Effective Date”), between ASP Isotopes, Inc. (including its successors and assigns, the “Company”) and ChemBridges LLC, a Puerto Rico limited liability company (“Advisor”).

WHEREAS, the Company is an emerging global leader in production of high purity isotopes for medical diagnostics and other applications.

WHEREAS, ChemBridges LLC (a Puerto Rico-based and registered company) is a strategic advisory firm, with extensive experience in analysis of chemical markets, chemical and allied products, technology, financial and investment analysis.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:

1. Term. Subject to earlier termination option (described in Section 5), the term of this Agreement shall be effective at the day of signing by both parties (the “Effective Date”) and shall continue for 36 months thereafter. This Agreement will be “evergreen”, automatically extended for another 12 months, unless terminated by a written notice from either party three months prior to the contract expiration. The period of time from the Effective Date through the termination of this Agreement is herein referred to as the “Term.”

2. Scope of Services.

The scope of Advisory role by ChemBridges LLC is to provide subject matter expertise on a wide range of commercial activity and strategic execution of key global business objectives, including but not limited to the advisory services on strategy, M&A, R&D, organic growth, operational optimization, commercial excellence, IR and corporate governance (collectively, the “Services”).

3. Provision of Advisory Services.

a) During the Term, Advisor shall retain Sergey Vasnetsov (“Principal”) to perform the Services with assistance of Principal’s research associates (if and as needed, depending on a project) (the Principal and any such research associates, each a “Representative” and collectively the “Representatives”). It is acknowledged and agreed that: (i) selection of type and timing of Services will be directed by the Company’s Chief Executive Officer for the benefit of the Company and (ii) Advisor is not providing continuous and regular supervisory or management services. Advisor shall devote time and resources as are necessary for the performance of the Services hereunder on an as-needed basis, as may reasonably be requested by Company and agreed to by Advisor.

b) Subject to Section 12(a), (b) and (c), and provided Advisor performs the Services as required by this Agreement, nothing in this Agreement shall prohibit Advisor from providing consulting or advisory services to any Person other than a Competitor. In this Agreement:

a “Person” means any individual, corporation (including any non-profit corporation), general or limited partnership, limited liability company, joint venture, association, organization, or any other entity; and

b “Competitor” means any Person that directly or indirectly competes with the Company or any of its affiliates or subsidiaries in the business of sourcing, developing, selling, marketing, or producing of isotopes.

c) Advisor acknowledges and agrees to be responsible for providing its own office space and office equipment, and to be available for communication with Company as may be reasonably requested via telephone, video conferences and email. Advisor further acknowledges that advisory services may require his domestic or international travel.

d) As an independent contractor, Advisor is responsible for paying appropriate taxes to relevant government entities. The parties agree that by virtue of the provision of the Services under this Agreement, Advisor shall not be entitled to any Company benefits, including but not limited to life insurance, accident and health insurance, death benefits, qualified pension or retirement plan, vacations, sick days or other benefits that Company provides to its full-time employees.

a) Within ten (10) business days following the Effective Date, the Board of Directors of the Company (the "Board") will grant to Advisor 600,000 shares of restricted stock (the "Restricted Shares") under the Company's 2021 Stock Incentive Plan (the "SIP"). The Restricted Shares shall vest in three (3) equal annual installments beginning on the first anniversary of the Effective Date, and all vested shares immediately become unrestricted common shares, the property of Advisor. The Restricted Shares will be subject to the terms of the SIP and a form of award agreement approved by the Board. Any unvested Restricted Shares will be forfeited to the Company for no consideration upon termination of this Agreement.

b) On the last day of each of the first eight calendar quarters following the first anniversary of the Effective Date, the Board will grant to Advisor an unrestricted award of common stock of the Company (each a "Common Stock Award") with a value of One Hundred Sixty Thousand Dollars ($160,000) annually. The number of shares granted in each Common Stock Award shall be determined by dividing $40,000 by the fair market value per share of Common Stock, as determined in good faith by the Board (which, if the Company's common stock is publicly traded on a national securities exchange shall be the closing price per share on the trading day immediately preceding the applicable Common Stock Award grant date, as reported by the principal trading market for the Company's common stock).

(b) Non-Solicitation. During the Term and for a period of three (3) years thereafter, Advisor shall not interfere with the Company’s relationship with, or endeavor to entice away from the Company, any person who, on the date of the termination of the Term and/or at any time during the one year period prior to the termination of the Term, was an employee, contractor, service provider, customer, or vendor of the Company or otherwise had a material business relationship with the Company.

(c) No Conflict. Advisor will not engage in any activity that creates an actual or perceived conflict of interest with the Company, regardless of whether such activity is prohibited by Company’s conflict of interest guidelines or this Agreement, and Advisor agrees to immediately notify the Board before engaging in any activity that could reasonably be assumed to create a potential conflict of interest with Company. Advisor shall not engage in any activity that is in direct competition with the Company or serve in any capacity (including, but not limited to, as an employee, consultant, advisor or director) in any company or entity that competes directly or indirectly with the Company without the approval of the disinterested members of the Board. Nothing in this Section 6(c) shall prohibit Advisor from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) a passive owner of any class of securities of a corporation, which are either private or publicly traded, so long as Advisor has no active participation in the business of such corporation or (iii) serving as an employee, consultant, director, advisor or board member of any other company that does not engage in any activity that is in direct competition with the Company.

(d) Remedies. Advisor agrees that any breach of the terms of this Section 12 would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law; Advisor therefore also agrees that in the event of said breach or any threat of breach, the Company shall be entitled to an immediate injunction and restraining order to prevent such breach and/or threatened breach and/or continued breach by Advisor and/or any and all entities acting for and/or with Advisor without having to prove damages or paying a bond, in addition to any other remedies to which the Company may be entitled at law or in equity. The terms of this paragraph shall not prevent the Company from pursuing any other available remedies for any breach or threatened breach hereof, including, but not limited to, the recovery of damages from Advisor. Advisor acknowledges that the Company would not have entered into this Agreement had Advisor not agreed to the provisions of this Section 12.

(e) During the Term, and at all times thereafter, Advisor shall cooperate with the Company, at the Company’s sole cost and expense (not including legal fees and expenses that Advisor may incur by retaining independent counsel), with respect to matters about which Advisor has knowledge, including, without limitation (i) matters involving any review, audit or investigation by the Company and (ii) any pending or threatened claim, demand, action, cause of action, suit, litigation, or administrative or arbitral proceeding, hearing or review, including, without limitation, any request from a regulatory or similar agency, involving the Company.

(f) The provisions of this Section 12 shall survive any termination of the Term, and the existence of any claim or cause of action by Advisor against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the covenants and agreements of this Section 12.
