INTRODUCTION This Code of Business Conduct and Ethics (the "Code") embodies the commitment of Reunion Gold Corporation (“Reunion”) and all its wholly-owned subsidiaries (the “Subsidiaries”) to conduct their business in accordance with all applicable laws, rules and regulations and the highest ethical standards. All directors, officers, employees and contractors engaged by Reunion or the Subsidiaries (collectively, the "Company") are expected to adhere to the principles and procedures of this Code. “You” as used in this Code refers to all such persons, as appropriate. The Company expects you to comply at all times with the following principles which serve as the foundation of this Code: Act ethically and honestly Avoid actual or apparent conflicts of interest Make decisions which are in the best interests of the Company Accept responsibility and be accountable for actions taken Conduct business in an environmentally and socially responsible manner Select and treat all employees in a respectful, fair and equitable manner and foster a work environment that is safe and healthy and free from discrimination, harassment, intimidation and hostility of any kind Obey all laws and regulations governing the conduct of the Company’s business In addition to your obligation to comply with this Code, it is your responsibility to prevent others from violating these standards if you are in a position to do so. If you are not in a position to do so, it is your responsibility to bring the matter to the attention of a supervisor or member of senior management who is in a position to take appropriate action, or to the attention of an independent member of the board of directors of Reunion (the “Board”). All contractors and suppliers with whom the Company does business are expected to be aware of and adhere to those principles and procedures of the Code that apply to them. If you retain a contractor or supplier, it is your responsibility to make them aware of the contents of this Code and require that they agree to abide by the provisions of the Code in their dealings with and on behalf of the Company. Failure to observe the terms of the Code may result in disciplinary action, up to and including termination of employment or office, or removal from the Board. Violations of the Code may also constitute violations of law, and may result in civil or criminal penalties. 1. COMPLIANCE WITH LAWS In representing the Company, you must act in compliance with all applicable federal, provincial, state and local laws and regulations. You should recognize that noncompliance may have adverse financial and other consequences for you and for the Company. You should be sufficiently familiar with any laws and regulations and Company policies and procedures that apply to your area of work and responsibility so that you are able to recognize possible breaches and to know when to seek advice. If in doubt, you should discuss the matter with a member of senior management. 2. CONFLICTS OF INTEREST A conflict of interest occurs when your private interests, or the private interests of your family, interfere, or appear to interfere, in any way with the best interests of the Company. You must avoid any direct or indirect involvement or situation that might result in such a conflict or create the appearance of such a conflict. Whether a situation involves a conflict of interest depends on all of the circumstances. The following are examples of conflict of interest situations which generally must be avoided, or which may raise a question: you take actions or have private interests that may make it difficult for you to perform your work effectively and in the best interests of the Company you use your employment or position in the Company to derive improper personal benefits, including benefits for your family members or related third parties you receive revenues or benefits from suppliers, competitors or customers of the Company Any activity that could give rise to conflicts of interest is prohibited unless specifically approved in advance. Where a conflict involves a Board member (e.g. where a Board member has an interest in a material contract or material transaction involving the Company), the Board member involved will be required to disclose his or her interest to the Board and refrain from voting at the Board meeting of the Company considering such contract or transaction in accordance with applicable law. Where a conflict involves a senior officer, approval of the Board will be required. Where a conflict involves an employee, approval of a member of senior management will be required. Some conflicts are clear-cut, and others are not. Any situation involving “related-party transactions” or “non-arm’s length relationships” that can result in a gain to you at the expense of the Company creates a conflict of interest. In the event that a potential conflict of interest involving you arises, and you are an employee of the Company, you must immediately notify your direct supervisor who may contact a senior officer of the Company, if appropriate. If you are an officer or director of the Company, you must immediately notify a senior officer or director of the Company who will assess the issue, if necessary, with the advice of legal counsel. Full and early disclosure enables you to resolve unclear situations and provides the opportunity to avoid or resolve conflicting interests before any difficulty arises. 3. CORPORATE OPPORTUNITIES You are expected to advance the Company's legitimate business interests when the opportunity to do so arises. You may not take for yourself (or direct to a third party) a business opportunity that is discovered through the use of the Company's property, information or position, except where the Board, after receiving the necessary information concerning the opportunity has elected not to avail itself of the opportunity in compliance with applicable corporate law. More generally, you are prohibited from using corporate property, information or position to compete with the Company. The line between personal benefits and those of the Company is often difficult to draw and sometimes both personal benefits and benefits to the Company may be derived from certain activities. If you have any doubt as to whether any activity you are contemplating violates this requirement, you must refer the issue to a member of senior management who will assess the issue with, if necessary, the advice of legal counsel. 4. PROTECTION AND PROPER USE OF COMPANY ASSETS You are entrusted with the care, management and cost-effective use of the Company’s property and you are not to make use of these resources for your own personal benefit or for the personal benefit of anyone else. You may only use Company assets, such as funds, products or computers, vehicles, mineral samples, and data, for legitimate business purposes or as otherwise approved by management, and never for an unauthorized or illegal purpose. As well, if you become aware of possible fraud or theft, you should report this immediately to your supervisor or to a member of senior management for investigation. You are responsible to ensure that all Company property assigned to you is maintained in good condition, and you should be able to account for such equipment. Any disposition of Company property should be for the benefit of the Company and not for personal benefit. You are to return all documents, data and property (including without limitation, computer hardware and software, databases, cellular phones, credit cards, books, etc.) in your possession upon termination of your employment or office for any reason. 5. CONFIDENTIALITY OF INFORMATION From time to time, you may be exposed to confidential information. Confidential information includes all material non-public information including but not limited to information about strategic plans, financial information, exploration and development results or reports, information regarding negotiations, agreements or other dealings between the Company and others, or employee-related information. It also includes information that suppliers and partners have entrusted to us. You are to take all reasonable measures to protect the confidentiality of such information acquired in connection with your activities on behalf of the Company. In addition, you must use confidential information only for the Company’s legitimate business purposes, and not for your personal benefit or the benefit of anyone else. It is your responsibility to determine what information is confidential and ensure that you use and disclose it only in the performance of your duties with the Company. If you are unsure, consider the information to be confidential until you obtain clarification. If your employment or office terminates, you will continue to be bound to your obligations of confidentiality to the maximum extent permitted by law. 6. INTEGRITY OF RECORDS AND FINANCIAL DISCLOSURE As a public company, it is of critical importance that the Company's financial filings with the appropriate regulatory authorities be accurate and timely. Depending on your position with the Company, you may be called upon to provide necessary information to ensure that the Company's public financial and other reports are complete, fair and understandable. You must comply with prescribed accounting policies and procedures and internal controls at all times. All records must accurately reflect and properly describe the transactions they record. All assets, liabilities, revenues and expenses must be properly recorded on a timely basis in the books of the Company. You must be vigilant in preventing fraud and dishonesty, and report immediately any evidence of wrongdoing. If you have any concerns as to weaknesses in the Company’s accounting system or in the Company’s internal controls; or if you believe that any instances of fraud, or incorrect or questionable accounting practices may have occurred; or if you believe that any instances of fraudulent, incorrect or questionable practices may have occurred in connection with the preparation of the Company’s financial statements, you should consult with your immediate supervisor or with senior management. Alternatively, you may follow the procedures outlined in the Whistleblower Policy, available on the Company’s website. 7. SECURITIES TRANSACTIONS Restrictions on Trading Illegal insider trading refers generally to buying or selling a security, in breach of a fiduciary duty or other relationship of trust and confidence, while in possession of material, nonpublic information about the security. “Material” means information that might reasonably be expected to have a significant impact on the market value of the security; it can be positive or negative, and can relate to virtually any aspect of a company’s business. Insider trading violations may also include "tipping" such information, securities trading by the person "tipped," and securities trading by those who misappropriate such information. In general, you and your family members may trade in Company securities unless: • a Blackout Period (see below) is in place, or • you have knowledge of material, non-public information. If a Blackout Period exists, or if you have knowledge of material, non-public information, neither you nor your family members may trade in Company securities. For purposes of this policy, “family member” means your spouse (married or common-law), your minor children, any person substantially dependent on you for support, and other persons who share a residence with you. This prohibition also applies to trading in the securities of other public companies, where directors, officers and employees of the Company come into a special relationship with another public company by acquiring undisclosed material information about the other company, frequently as a joint venture partner of or as a party to an undisclosed material transaction with that other public company. From time to time, the Company may institute a period during which trading in Company securities is prohibited because of the existence of undisclosed material information (a “Blackout Period”). If a Blackout Period is instituted, a notification will be sent to appropriate employees, officers and directors, generally by e-mail from the corporate secretary. A notification of the termination of a Blackout Period will be sent in the same manner. The existence of a Blackout Period is itself an item of confidential information that is not to be disclosed to persons outside of the Company. Following the public announcement of material information, a reasonable period of time must elapse in order for the market to react to the information. The Company is of the view that one full trading day following publication will generally be a reasonable waiting period before the disclosed information is deemed to be public. A contravention of these trading restrictions can lead to criminal prosecution, fines and potential civil liability. 8. HARASSMENT OR DISCRIMINATION The Company promotes the welfare of its people by fostering a work environment of mutual respect, tolerance, and inclusion. The Company supports the principle that every individual must be accorded an equal opportunity in all aspects of employment. The Company is committed to providing equal employment opportunities to all employees and applicants without regard to race, religion, color, sex, sexual orientation, age, national or ethnic origin, or disability (unless demands of the position are prohibitive). You must treat others in the workplace and work environment with professional courtesy and respect at all times. You must not subject a colleague to unwelcome sexual advances, requests for sexual favors or other verbal (including through emails) or physical conduct which might be construed as sexual in nature. Such conduct may constitute sexual harassment under the laws where the Company operates and may be the basis for legal action against the offending individual or the Company or both. You must also not engage in any behavior which would, directly or indirectly, discriminate based upon race, religion, color, sex, sexual orientation, age, national or ethnic origin or disability. If you believe that you have been subjected to sexual harassment or discrimination in the workplace, you should immediately contact a member of senior management of the Company. Your identity will be kept strictly confidential and will not be revealed by the Company's management without your permission. The alleged harassment or discrimination will be thoroughly investigated and documented by the Company and appropriate action will be taken. The Company will not tolerate retaliation of any kind against those who make complaints in good faith. 9. USE OF E-MAIL AND INTERNET SERVICES E-mail and internet systems are provided to help you do work. Incidental and occasional personal use is permitted, but never for personal gain or any improper purpose, and your use must not interfere with your duties to the Company. "Flooding" systems with junk mail and trivia hampers the ability of our systems to handle legitimate Company business and is prohibited. Access, transmission and downloading of any information that could be insulting or offensive to another person, such as sexually explicit messages, ethnic or racial slurs, or messages that could be viewed as harassment are expressly prohibited. E-mail and Internet systems and electronic data contained therein are the property of the Company and there is no expectation of privacy for those who use these systems. Unless prohibited by law, the Company reserves the right to access and disclose information contained on information technology systems as necessary for business purposes. 10. PAYMENT TO DOMESTIC AND FOREIGN OFFICIALS You must comply with all applicable laws prohibiting improper payments to domestic and foreign officials, including the Corruption of Foreign Public Officials Act (Canada) (the “Act”). The Act makes it illegal for any person, in order to obtain or retain an advantage in the course of business, directly or indirectly, to offer or agree to give or offer a loan, reward, advantage or benefit of any kind to a foreign public official or to any person for the benefit of a public official. Foreign public officials include persons holding a legislative, administrative or judicial position of a foreign state, persons who perform public duties or functions for a foreign state (such as persons employed by board, commissions or government corporations), officials and agents of international organizations, foreign political parties and candidates for office. Although “facilitated payments” or certain other transactions may be exempted or not illegal under applicable law, the Company’s policy is to avoid them. Violation of the Act is a criminal offence, subjecting the Company upon conviction to substantial fines and penalties and any officer, director or employee acting on behalf of the Company to imprisonment and fines. If you have a question about the application of this part of the Code to a particular situation, you should contact a senior officer of the Company who, with the advice of counsel as necessary, will determine acceptability from both a legal and a corporate policy point of view. 11. GIFTS AND ENTERTAINMENT The giving or accepting of gifts can adversely affect the Company’s reputation for fair dealing and also create conflicts of interest. You should avoid: giving or offering to give any gift, favour, entertainment, reward, or any other thing of value that might influence or appear to influence the judgment or conduct of the recipient in the performance of his or her job. This includes transactions with government personnel, customers and suppliers. Such action may damage the Company’s reputation for fair dealing and may be illegal. accepting or soliciting a gift, favour, or other thing of value that is intended to, or might appear to, influence your decision-making or professional conduct. In addition to damaging the Company’s reputation for fair dealing, receipt of such gifts could interfere with your ability to make judgments solely in the best interest of the Company, and thus create the appearance of a conflict of interest. You may give or receive unsolicited gifts or entertainment only in cases where the gifts or entertainment are of nominal value, are customary to the industry, will not violate any laws, and will not influence nor appear to influence the recipient’s judgment or conduct. The following are guidelines regarding acceptable gifts and entertainment: modest gifts, such as logo items, pens, calendars, caps, shirts and mugs reasonable invitations to business-related meetings, conventions, conferences or product training seminars invitations to social, cultural or sporting events may be accepted if the cost is reasonable and attendance serves a customary business purpose such as networking (e.g. meals, holiday parties and tickets) invitations to golfing, fishing, sports events or similar trips that are usual and customary for your position within the Company and the industry, and promote good working relationships with customers and suppliers 12.

WAIVERS OF THE CODE The Company will make every effort to resolve potential conflicts of interest or Code-related issues that may arise when these are disclosed promptly to management and the parties involved have acted in good faith.

1. PURPOSE OF THIS POLICY The purpose of this corporate disclosure policy (the “Policy”) is to summarize Reunion Gold Corporation (“Reunion”) corporate disclosure and communication practices and to provide guidance to the directors and officers and certain employees and consultants of Reunion and its subsidiaries (together with Reunion, the “Company”) who may, from time to time, possess confidential information. ​ The objectives are (i) for the Company to make timely, informative and accurate disclosure of material information, (ii) prevent disclosure of such material information being made on a selective basis and (iii) provide guidance to the Company’s directors, officers and employees to preserve the confidentiality of undisclosed material information. ​ Any questions regarding this Policy should be addressed to a member of the Disclosure Committee. 2. APPLICATION OF THIS POLICY ​ This Policy applies to all directors, officers, employees and certain consultants of the Company, as well as those persons authorized to speak on behalf of the Company. ​ This Policy covers disclosure in documents filed with the securities regulators and written letters to shareholders, presentations by senior management, information contained on the Company’s website and other electronic communications. It also covers any oral communication with the public in general, including investors, brokers, analysts, interviews with the media as well as speeches, press conferences, conference calls and webcasts. ​ A copy of this Policy will be distributed from time to time to all directors, officers, employees and certain consultants of the Company, as well as any other person authorized to speak on behalf of the Company to ensure they are all aware of this Policy. As well, this Policy will be made available on the Company’s website. All directors, officers, employees and certain consultants will be informed whenever significant changes are made to this Policy. New directors, officers, employees and certain consultants will be provided with a copy of this Policy and educated about its importance. 3. DISCLOSURE COMMITTEE A disclosure committee (the "Disclosure Committee") oversees the Company’s disclosure practices, including monitoring the effectiveness of and compliance with this Policy. The Disclosure Committee consists of the Chief Executive Officer (“CEO”), the Chief Financial Officer (“CFO”), the Chief Operating Officer (“COO”) and the Corporate Secretary. The Chair of the Disclosure Committee is the CEO. In carrying out its functions, the Disclosure Committee may meet by telephone, and it may act by majority decision. ​ The Disclosure Committee is responsible for reviewing and authorizing all disclosure (including electronic, written and prepared oral disclosure) in advance of its public release, as well as for monitoring the Company’s website. 4. DESIGNATED SPOKESPERSONS The primary spokespersons for the Company are the Executive Chairman, President and CEO, CFO, COO and Corporate Secretary (“Designated Spokespersons”). Spokespersons may, from time to time, designate others to speak on behalf of the Company or to respond to specific inquiries. ​ Employees who are not authorized spokespersons must not respond under any circumstances to inquiries from the public, shareholders, the investment community, the media or others if the inquiries pertain to a development or event that may be Material Information. All such inquiries should be referred to the Executive Chairman or CEO. 5. OBLIGATIONS TO DISCLOSE MATERIAL INFORMATION The Company is subject to continuous disclosure and reporting obligations under Canadian securities laws and the TSX Venture Exchange (“TSXV”) policies. These obligations require the Company to provide appropriate disclosure of material information, and to ensure that employees and others do not benefit from having and using undisclosed material information. “Material Information” is any fact, event, circumstances or change in the activities, business or assets of the Company that is not known to the public and that results in, or would reasonably be expected to result in, a significant change in the market price or value of the securities of Reunion; it also means any information that would reasonably be expected to have a significant influence on any reasonable investor’s decision to buy, sell or hold securities of Reunion. ​ All employees have the responsibility to inform senior management on a timely basis of events or developments that might constitute Material Information. As soon as senior management of the Company becomes aware of a potential development that may require the Company to disclose Material Information, they must inform a member of the Disclosure Committee. The Disclosure Committee (or a majority of its members) will then meet as promptly as practicable and determine if the development constitutes Material Information that must be disclosed. ​ At all times, the Company shall act to disclose Material Information in accordance with all applicable securities laws, rules and regulations, and in accordance with this Policy. Unfavourable Material Information must be disclosed as promptly and completely as favourable Material Information. 6. TIMELY DISCLOSURE OF MATERIAL INFORMATION The Company must disclose Material Information concerning its business and affairs forthwith upon the information becoming known to management, or upon it becoming apparent that the information is material. The Company shall immediately issue and file a news release disclosing the nature and substance of the Material Information. If Material Information constitutes a material change, a material change report must be filed within the prescribed period. ​ Where the nature of the Material Information to be disclosed in a news release requires pre-filing under the policies of the TSXV, prior notice of the news release must be provided to Market Surveillance of Investment Industry Regulatory Organization of Canada (“IIROC”) to seek approval of the news release, to watch for unusual trading and to determine if a halt in trading is required. ​ All news releases announcing Material Information must be approved by the Disclosure Committee. ​ News releases announcing Material Information must be disseminated through a news wire service approved by the TSXV that provides simultaneous national distribution to stock exchange members, relevant regulatory bodies and appropriate financial media. 7. EXCEPTION TO TIMELY DISCLOSURE REQUIREMENT In restricted circumstances, securities legislation and TSXV policies allows Material Information to be kept confidential for a limited period of time if early disclosure would be unduly detrimental to the Company’s interests (for example, if release of the information would prejudice negotiations in a corporate transaction). In such a case, the Company shall immediately file a confidential material change report, and may otherwise keep news of the material change confidential until the Disclosure Committee determines that it is appropriate to disclose it publicly, or the Company is compelled to disclose it under applicable continuous disclosure obligations. ​ If disclosure of Material Information is delayed, complete confidentiality must be maintained. That is, the Material Information should not be disclosed to anybody, inside the Company or outside, except those who have need to know in the necessary course of the Company’s business. 8. SELECTIVE DISCLOSURE This Policy strictly prohibits selective disclosure of Material Information. It is the responsibility of the Company to ensure that undisclosed Material Information is disseminated in such a way that all members of the public have equal access to the information. Substantial security holders and analysts in particular must not receive preferential treatment in the matter of information disclosure. ​ Unless otherwise directed by the Disclosure Committee, the Company will publicly disclose Material Information first before selectively disclosing it to any person, unless disclosing such information to the person prior to public dissemination is “in the necessary course of business.” Consultation with the Company’s legal counsel is recommended before making selective disclosure considered to be “in the necessary course of business.” ​ If previously undisclosed Material Information has been inadvertently disclosed to an analyst or investor, or any other person not bound by an express confidentiality obligation, the person responsible for the disclosure, and any other employee, officer or director learning of it, must contact a member of the Disclosure Committee which will ensure that the information is broadly disclosed immediately via news release. 9. RESTRICTIONS ON TRADING Securities laws prohibit any insider or anyone having a close or special relationship with the Company from purchasing or selling securities of the Company when any such person has knowledge of material non-public information about the Company’s activities, business, operations and assets.

PROVISION OF FORWARD-LOOKING INFORMATION To help the investor community, the Company sometimes discloses forward-looking information. Where it does so, the Company shall ensure that prospective statements are clearly identified as forward looking and are accompanied by meaningful cautionary language identifying important factors that could cause actual results to differ materially from those projected in the statements. 12. CORRECTIONS The Company shall immediately correct disclosure where it subsequently learns that the earlier disclosure contained a material error at the time it was given and the correction would constitute Material Information. The Disclosure Committee shall ensure that a news release is issued immediately to correct the error and that appropriate notifications are made to the TSXV so that a halt to trading may be instituted, if necessary. 13. WEBSITE AND PRESENTATIONS The Company shall post on its website all supplemental information provided by the Company to analysts, institutional investors and other market professionals, including fact sheets, slides of investor presentations and other materials distributed at analyst or industry presentations. ​ Any new documents or information items to be added to the Company’s website will be referred to the Disclosure Committee for review before being posted or made public. ​ The Company shall ensure that the website is up-to-date and accurate. 14.

RUMOURS The Company will not comment, affirmatively or negatively, on rumours, including those rumours disseminated on the Internet. The Company’s spokespersons will respond consistently to those rumours, saying “It is our policy not to comment on market rumours or speculation.” If a stock exchange or securities regulatory authority requests the Company to make a statement in response to a market rumour, the Disclosure Committee will consider the matter and decide whether to issue a press release.

ADOPTION This Policy was adopted by the Board on June 23, 2011 and reapproved, with clerical changes, on August 16, 2018. ​ *****

1. PURPOSE OF THIS POLICY The purpose of this insider trading policy (the “Policy”) is to summarize the insider trading restrictions to which directors, officers, employees, and others having access to material non public information (collectively referred to as “Insiders”) about Reunion Gold Corporation (“Reunion”) and its subsidiaries (together with Reunion, the “Company”) are subject under securities laws and to provide guidelines for trading Reunion’s shares or other securities. ​ This Policy should be read in conjunction with the Corporate Disclosure Policy adopted by Reunion. 2. PROHIBITED TRADING Securities laws prohibit anyone having a close or special relationship with the Company from purchasing or selling securities of Reunion when any such person has knowledge of material non public information about the Company. At the appropriate time, the Company discloses material information publicly via news release or otherwise. However, prior to such public disclosure, Insiders may have knowledge of material non-public information and, under any such circumstances, they must exercise the utmost care in handling such material non public information to avoid legal and ethical violations. ​ A material non public information about the Company means any fact, event, circumstances or change in the activities, business or assets of the Company that is not known to the public and that results in, or would reasonably be expected to result in, a significant change in the market price or value of the securities of Reunion; it also means any information that would reasonably be expected to have a significant influence on any reasonable investor’s decision to buy, sell or hold securities of Reunion. This would include, but is not limited to, non public information regarding: 1. acquisition or disposition of material assets; ​​ 2. mineral discoveries or material developments affecting the Company’s resources or exploration results; ​​ 3. take-overs, mergers, consolidations, amalgamations or reorganizations; ​ 4. changes in the capital structure and changes in share ownership that may affect control of Reunion; ​ 5. public or private sale of securities of Reunion; ​ 6. changes in capital expenditure plans or corporate objectives; ​ 7. significant changes in the Company’s management or board of directors; ​ 8. significant litigation; ​ 9. major labour disputes or disputes with major contractors, suppliers, or customers; ​ 10. events of default under financing or other material agreements; and ​ 11. any other change in the business, affairs or property of the Company that could reasonably be expected to materially affect the price or value of the securities of Reunion or have an influence on a reasonable investor’s investment decision. ​ Securities laws also prohibit “tipping”, defined as communicating material non-public information to another person (including family and friends), except on a need-to-know basis in the necessary course of business. All Insiders must ensure that they do not divulge such material non-public information to any unauthorized person, whether or not such person may trade on the information. They are also responsible for ensuring compliance by their families and other members of their households and entities over which they exercise voting or investment control. 3. TRADING GUIDELINES All those with access to material undisclosed information are prohibited from using such information in trading in the Company's securities until the information has been fully disclosed and a reasonable period of time has passed for the information to be disseminated. This prohibition applies not only to trading in the Company’s securities, but also to trading in other securities whose value may be affected by such material undisclosed information. ​ In order to ensure that perceptions of improper insider trading do not arise, Insiders should not “speculate” in securities of the Company. For the purpose of this Policy, the word “speculate” means the purchase or sale of securities with the intention of reselling or buying back in a relatively short period of time in the expectation of a rise or fall in the market price of such securities. Speculating in such securities for a short-term profit is distinguished from purchasing and selling securities as part of a long-term investment program. Insiders shall not at any time sell securities of the Company short or buy or sell a call or put option in respect of securities of the Company or any of its affiliates. ​ Insiders should also avoid putting open orders to purchase or sell securities of Reunion but in the event they need to do so, the open order shall expire no later than the close of trading on the last trading day of the week the open order was entered into. ​ In addition, Insiders may not trade at any time without prior clearance. Clearance must be obtained in writing from the General Counsel or the Chief Financial Officer before buying or selling securities of Reunion or exercising any of Reunion's stock options. Unless it is clear that there is no undisclosed material information concerning the Company, clearance to complete a proposed trade will be denied. The Company's policy is to be cautious and conservative when granting or denying trading clearance to avoid embarrassment and tarnish the Company's reputation, especially among its shareholders and analysts. Clearance, if granted, will be effective for five business days provided such Insider is not otherwise in possession of material, non-public information. If for any reason the trade is not completed within five (5) business days, clearance must be obtained again before stock may be traded. The Company reserves the right to revoke the clearance, if necessary. 4. BLACKOUT PERIODS The Company may from time to time impose a trading blackout if there is a pending material development. All persons receiving notice of a trading blackout or having knowledge of a trading blackout are prohibited from trading in securities of Reunion. The blackout period will commence at the time that the Company’s General Counsel, or another individual designated by the CEO, disseminates an email to confirming same. The Company must allow the market time to absorb the information before Insiders can resume trading after the release of material information. In general, the Company has stipulated that a minimum of one clear trading day be allowed after the earlier of (i) the announcement of the material information and (ii) the dissemination of an email from the General Counsel or designated individual confirming that the trading blackout is lifted. ​ The existence of a blackout is in itself an item of confidential information that is not to be disclosed to persons outside of the Company. ​ During blackout periods, Insiders must also avoid discussions with analysts, private briefings and interviews to the maximum extent reasonable. During a blackout period, the Company, through its Disclosure Committee (formed under the Company’s Corporate Disclosure Policy), may, under certain circumstances, permit the exercise of options or warrants provided that the common shares acquired upon exercise of such options or warrants are not traded until the blackout period expires. 5. LIABILITY FOR INSIDER TRADING Under Canadian securities laws, persons who violate “insider trading” and/or “tipping” prohibitions may be subject to a number of criminal sanctions and civil liabilities including being liable: (i) to compensate the seller or purchaser of the securities for damages resulting from the trade; (2) to account to the relevant entity for any benefit or advantage received or receivable by the insider resulting from the trade on the basis of undisclosed material information and (3) for substantial fines (for example, under the Ontario Securities Act, up to the greater of $5 million and triple the amount of the profit made or the loss avoided by the person by reason of the violation) and imprisonment (for example, under the Ontario Securities Act, to a maximum term of not more than five years less a day). 6. INSIDER REPORTING Reporting insiders are required to electronically file insider reports through the System for Electronic Disclosure by Insiders (“SEDI”). An initial report must be filed within 10 days of becoming a reporting insider and report on all trades made in the securities of Reunion must be filed within 5 days of the day any trade is made. Trades include the grant of options or exercise thereof as well as a change in nature of the ownership of the securities (e.g. a disposition to a company controlled by the insider or a determination that the securities are to be held in trust for another person). Failure to file a report on time will result in late fees being levied on the reporting insider. ​ It is each reporting insider's personal responsibility to ensure that all requisite insider trading reports are filed on SEDI within the statutory time limits. 7. POLICY REVIEW AND DISTRIBUTION The Company’s Board of Directors will review and evaluate this policy annually to determine if the Policy effectively ensures accurate and timely disclosure in accordance with its disclosure obligations. ​ A copy of this Policy will be distributed from time to time to all Insiders to ensure they are all aware of this Policy. As well, this Policy will be made available on the Company’s website. New Insiders will be provided with a copy of this Policy and educated about its importance. ​ Any questions regarding this Policy should be addressed to the Company’s General Counsel or Chief Financial Officer. 8. ADOPTION This Policy was adopted by the Board on June 23, 2011 and reapproved, with clerical amendments only, on August 16, 2018 ​ *****
