Information Circular - Proxy Statement dated May 1, 2023 for the Annual and Special Meeting of
Shareholders of Hammerhead Energy Inc. to be held on Thursday, June 8, 2023.

This Information Circular is furnished in connection with the solicitation of proxies for use at the annual and special meeting, and any adjournment or postponement thereof, of the shareholders of the Company to be held at 2:00 p.m. (Calgary time) on Thursday, June 8, 2023, at the offices of Burnet, Duckworth & Palmer LLP, 2400, 525 - 8th Avenue S.W., Calgary, Alberta.

If you are a registered shareholder and are unable to attend the meeting or any adjournment or postponement thereof in person, please exercise your right to vote by dating, signing, and returning the accompanying form of proxy for use at the meeting or any adjournment or postponement thereof to Computershare Trust Company of Canada, our transfer agent. To be valid, completed proxy forms must be dated, completed, signed and deposited with Computershare Trust Company of Canada, (i) by mail using the enclosed return envelope or one addressed to Computershare Trust Company of Canada, Proxy Department, 135 West Beaver Creek, P.O. Box 300, Richmond Hill, Ontario, L4B 4R5, (ii) by hand delivery to Computershare Trust Company of Canada, 8th Floor, 100 University Avenue, Toronto, Ontario, M5J 2Y1, or (iii) by facsimile to (416) 263-9524 or 1-866-249-7775. If you vote through the internet, you may also appoint another person to be your proxyholder. Please go to www.investorvote.com and follow the instructions. You will require your 15-digit control number found on your proxy form. Your proxy or voting instructions must be received in each case no later than 2:00 p.m. (Calgary time) on June 6, 2023, or, if the meeting is adjourned or postponed, 24 hours (excluding Saturdays, Sundays, and holidays) before the beginning of any adjourned or postponed meeting. If you receive more than one proxy form because you own Common Shares registered in different names or addresses, each proxy form should be completed and returned.

The instrument appointing a proxy must be in writing and must be executed by you or your attorney authorized in writing or, if you are a corporation, under your corporate seal or by a duly authorized officer or attorney of the corporation.

The persons named in the enclosed form of proxy are our directors and/or officers. As a shareholder you have the right to appoint a person or company, who need not be a shareholder, to represent you at the meeting. To exercise this right, you should insert the name of the desired representative in the blank space provided on the form of proxy and strike out the other names or submit another appropriate proxy.

Only shareholders of record at the close of business on May 1, 2023, will be entitled to vote at the meeting, unless that shareholder has transferred any Common Shares after that date and the transferee shareholder, not later than 10 days before the meeting, establishes ownership of the Common Shares and demands that the transferee's name be included on the list of shareholders entitled to vote at the meeting.

The information set forth in this section is significant to you if you do not hold your Common Shares in your own name. Only proxies deposited by shareholders whose names appear on our records as the registered holders of Common Shares can be recognized and acted upon at the meeting. If your Common Shares are listed in your account statement provided by your broker, then, in almost all cases, those Common Shares will not be registered in your name on our records. Such Common Shares will likely be registered under the name of your broker or an agent of that broker. In Canada, many of such Common Shares are registered under the name of CDS & Co., the registration name for The CDS Clearing and Depository Services Inc., which acts as nominee for many Canadian brokerage firms. Common Shares held by your broker, or their nominee can only be voted upon your instructions. Without specific instructions, your broker or their nominee is prohibited from voting your Common Shares.

Applicable regulatory policy requires your broker to seek voting instructions from you in advance of the meeting. Every broker has its own mailing procedures and provides its own return instructions, which you should carefully follow to ensure that your Common Shares are voted at the meeting. Often, the form of proxy supplied by your broker is identical to the form of proxy provided to registered shareholders. However, its purpose is limited to instructing the registered shareholder how to vote on your behalf. Many brokers now delegate responsibility for obtaining instructions from clients to a mailing/tabulating agent who mails a scannable voting instruction form in lieu of the form of proxy. You are asked to complete and return the voting instruction form to them by mail or facsimile. Alternatively, you can use their website or call their toll-free telephone number to instruct them how to vote your Common Shares. They then tabulate the results of all instructions received and provide appropriate instructions respecting the voting of Common Shares to be represented at the meeting. If you receive a voting instruction form from a mailing/tabulating agent, it cannot be used as a proxy to vote Common Shares directly at the meeting as it must be returned to the mailing/tabulating agent well in advance of the meeting to have the Common Shares voted.

The Company is not using "notice-and-access" to send its proxy-related materials to shareholders, and paper copies of such materials will be sent to all shareholders. The Company will not send proxy-related materials directly to non-objecting beneficial shareholders and such materials will be delivered to non-objecting beneficial shareholders through Broadridge Financial Solutions, Inc. or the non-objecting beneficial shareholder's intermediary. The Company intends to pay for the costs of an intermediary to deliver proxy-related materials to objecting beneficial shareholders.

You may revoke your proxy at any time prior to a vote. If you or the person you give your proxy attends personally at the meeting, you or such person may revoke the proxy and vote in person. In addition to revocation in any other manner permitted by law, a proxy may be revoked by an instrument in writing executed by you or your attorney authorized in writing or, if you are a corporation, under your corporate seal or by a duly authorized officer or attorney of such corporation. To be effective the instrument in writing must be deposited with the President and Chief Executive Officer of the Company c/o 2700, 525 - 8th Avenue S.W., Calgary, Alberta, T2P 1G1, at any time prior to 2:00 p.m. (Calgary time) on the last business day preceding the day of the meeting, or any adjournment or postponement thereof, at which the proxy is to be used, or with the chair of the meeting on the day of the meeting, or any adjournment or postponement thereof.

This solicitation is made on behalf of our management. We will bear the costs incurred in the preparation and mailing of the form of proxy, notice of annual and special meeting and this Information Circular. In addition to mailing forms of proxy, proxies may be solicited by personal interviews, or by other means of communication, by our directors, officers and employees who will not be remunerated therefor.

The Common Shares represented by proxy in favour of management nominees will be voted or withheld from voting on any matter at the meeting. Where you specify a choice with respect to any matter to be acted upon, the Common Shares will be voted on the matter in accordance with the specification so made. If you do not provide instructions, your Common Shares will be voted in favour of the matters to be acted upon as set out herein. The persons appointed under the form of proxy, which we have furnished, are conferred with discretionary authority with respect to amendments or variations of those matters specified in the form of proxy and notice of annual and special meeting and with respect to any other matters which may properly be brought before the meeting or any adjournment thereof. At the time of printing this Information Circular, we know of no such amendment, variation, or other matter.

We are authorized to issue an unlimited number of Common Shares and first preferred shares (the "First Preferred Shares") in an amount equal to not more than 20% of the number of issued and outstanding Common Shares at the time of issuance of any First Preferred Shares. As at May 1, 2023, there were 90,973,622 Common Shares and nil First Preferred Shares issued and outstanding. As a holder of Common Shares, you are entitled to one vote for each Common Share you own.

To the knowledge of our directors and officers, as at May 1, 2023, no person or company beneficially owned, or controlled or directed, directly or indirectly, more than 10% of our Common Shares, other than as set forth below:

Pursuant to the SPAC Amalgamation, among other things: (a) each DCRD Class A ordinary share, par value $0.0001 per share (the "DCRD Class A Ordinary Shares") issued and outstanding (which, pursuant to the Domestication, was exchanged for one Class A common share of DCRD) immediately prior to the SPAC Amalgamation Effective Time was exchanged, on a one-for-one basis, for a Common Share; (b) each DCRD Class B ordinary share, par value $0.0001 per share issued and outstanding (which, pursuant to the Domestication, was exchanged for one Class B common share of DCRD) immediately prior to the SPAC Amalgamation Effective Time was exchanged, on a one-for-one basis, for a Class B common share in the authorized share capital of the Company which were deemed to be cancelled without repayment of capital; (c) each common share of NewCo outstanding was exchanged for one Common Share; (d) each common share purchase warrant of DCRD issued and outstanding immediately prior to the SPAC Amalgamation Effective Time was exchanged for a Warrant; (e) each unit of DCRD, consisting of one DCRD Class A Ordinary Share and one-half of one DCRD warrant, issued and outstanding immediately prior to the SPAC Amalgamation Effective Time was exchanged for one unit of the Company representing one Common Share and one-half of one Warrant; and (f) the Common Share held by Hammerhead was purchased for cancellation for cash equal to the subscription price for such common share of NewCo.

On the Closing Date, prior to the Company Amalgamation, among other things: (a) the articles of Hammerhead were amended to authorize the Class B common shares ("Hammerhead Class B Common Share") and concurrently, all of the then issued and outstanding common shares of Hammerhead were re-designated as Class A common shares of Hammerhead; (b) each Hammerhead Common Share held by certain employee borrowers was exchanged for one Hammerhead Class B Common Share; (c) each then issued and outstanding Hammerhead Class B Common Share was exchanged for one Common Share pursuant to the articles of the Company adopted at the Company Amalgamation Effective Time, in accordance with the Plan of Arrangement; and (d) each warrant to purchase Hammerhead Common Shares was either exchanged for Hammerhead Common Shares or cash, in each case, in accordance with the Plan of Arrangement.

The Common Shares and the Warrants are traded on the NASDAQ under the symbols "HHRS" and "HHRSW", respectively, and on the TSX under the symbols "HHRS" and "HHRS.WT," respectively.

At the meeting, our shareholders will receive and consider the financial statements of each of the Company, DCRD and Hammerhead for the year ended December 31, 2022 and the Auditors' Reports thereon, but no vote by our shareholders with respect thereto is required or proposed to be taken.

The Company Articles provide for a minimum of three directors and a maximum of eleven directors. The Company's by-laws provide that the number of directors shall be determined from time to time by our shareholders. There are currently eight directors on the Company Board. Accordingly, unless otherwise directed, it is the intention of management to vote proxies in the accompanying form in favour of fixing the number of directors to be elected at the meeting at eight.

The Company Board has fixed the number of directors to be elected at the meeting at eight members. You are being asked to cast your vote for the following eight directors:

Each director will hold office until the next annual meeting of our shareholders, or their successor is duly elected or appointed, unless their office is earlier vacated. If a vacancy among such nominees occurs because of death or for any reason prior to the meeting, the proxy will not be voted with respect to such vacancy.

The directors are elected annually, individually and by majority vote. The individual voting results of this meeting will be published by news release and on the SEDAR website at www.sedar.com after the meeting.

The Company has adopted a majority voting policy. In an uncontested election, any nominee for director who receives a greater number of votes "withheld" from his or her election than votes "for" his or her election (a "majority withhold vote") shall tender his or her resignation, for consideration by the Company Board, to the Chair of the Governance and ESG Committee promptly following certification of the shareholder vote, such resignation to be effective upon acceptance by the Company Board. If the Chair of the Governance and ESG Committee received a majority withhold vote, then he or she shall tender his or her resignation to the Chair of the Company Board. The Governance and ESG Committee will promptly consider the tendered resignation and will make a recommendation to the Company Board whether to accept or reject such resignation. In determining whether to recommend acceptance or rejection of the tendered resignation, the Governance and ESG Committee will consider all factors it deems relevant including, without limitation, the impact with respect to covenants in agreements or plans; and legal requirements, policies or guidelines (regulatory, securities or corporate laws, or stock exchange rules) for director numbers and qualifications.

The Company Board will consider the Governance and ESG Committee's recommendation not later than 90 days following the date of the shareholders' meeting at which the election occurred. In deciding whether to accept or reject the tendered resignation, the Company Board will consider the factors considered by the Governance and ESG Committee and any additional information and factors the Company Board believes to be relevant. It is expected that the Company Board will accept a resignation absent exceptional circumstances. If the Company Board determines not to accept a resignation, the reasons for rejecting the tendered resignation will be disclosed in a news release and a copy of the news release will be provided to the TSX and NASDAQ. If the Company Board decides to accept the director's resignation, the Governance and ESG Committee will recommend to the Company Board whether to fill the resulting vacancy or to continue with the reduced size of the Company Board.

Management recommends that shareholders vote FOR the election of each of these nominees. The persons named in the enclosed form of proxy intend to vote FOR the election of each of these nominees unless the shareholder specifies authority to do so is withheld.

The following information relating to the director nominees is based in part on our records and in part on information the nominees have provided to us.

(1) The Company was formed on February 23, 2023. As a result, there were no meetings in 2022.

The following table sets forth each such director's ownership of Company securities as at the date of this Information Circular:

(1) 1901 is the record holder of 7,036,020 Common Shares. Bryan Begley is one of the managing directors of 1901 Partners Management, LP which is the sole member of 1901 Lux Director, LLC, the Class A manager of 1901. Mr. Begley has shared voting and investment discretion with respect to the Common Shares held of record by 1901. As such, each of Mr. Begley, 1901 Lux Director, LLC and 1901 Partners Management, LP may be deemed to have or share beneficial ownership of the Common Shares held directly by 1901. Each such entity or individual disclaims any such beneficial ownership.

Except as otherwise disclosed herein or in connection with the other matters described below, none of our directors (nor any personal holding company of any of such persons) is, as of the date hereof, or was within 10 years before the date hereof, a director, chief executive officer or chief financial officer of any company (including us), that was subject to a cease trade order (including a management cease trade order), an order similar to a cease trade order or an order that denied the relevant company access to any exemption under securities legislation, in each case that was in effect for a period of more than 30 consecutive days that was issued while the director was acting in the capacity as director, chief executive officer or chief financial officer; or that was issued after the director ceased to be a director, chief executive officer or chief financial officer and which resulted from an event that occurred while that person was acting in the capacity as director, chief executive officer or chief financial officer.

None of our directors (nor any personal holding company of any of such persons) is, as of the date hereof, or has been within the 10 years before the date hereof, a director or executive officer of any company (including us) that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets other than as set forth below.

Mr. Michael Kohut was a director of Great Prairie Energy Services Inc. ("Great Prairie") on January 22, 2016, when it applied for and obtained an order from the Court of Queen's Bench of Alberta under the CCAA. Mr. Kohut resigned as a director of Great Prairie on January 22, 2016.

Mr. Bryan Begley was the chair of the board of directors of Legend Energy Services, LLC ("Legend"), a privately held company in the U.S. which had been one of the horizontal drilling industry's premier coiled tubing service specialists. Upon the downturn in the oil and gas industry, Legend worked together with its secured lender to sell its assets to a smaller operator. To be sure that its remaining assets were shared equitably by its remaining creditors, on October 26, 2021, Legend filed a voluntary Chapter 7 Petition in the United States Bankruptcy Court for the Eastern District of Texas. Mr. Begley ceased his position as a director of Legend on October 26, 2021.None of our directors (nor any personal holding company of any such persons) has, within the 10 years before the date hereof, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold the assets of the director.

Mr. Robert Tichio was a director of EP Energy Corporation and Castex Energy I, LLC, the general partner of Castex Energy 2005, L.P. Both entities previously filed for Chapter 11 reorganizations with the U.S. Bankruptcy Courts and have since emerged from bankruptcy proceedings. Mr. Tichio no longer serves as a director for either company.

None of our directors (nor any personal holding company of any of such persons) has been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory authority or any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor in making an investment decision.

Unless otherwise directed, it is management's intention to vote proxies in favour of Ernst & Young LLP, Chartered Professional Accountants, of Calgary, Alberta, as our auditors, to hold office until the next annual meeting of shareholders and to authorize the directors to fix their remuneration as such. Ernst & Young LLP were first appointed as auditors of Hammerhead on May 27, 2010 and of the Company on December 6, 2022.

The following table provides information about the fees billed to the Company and Hammerhead for professional services rendered by Ernst & Young LLP during the fiscal years of 2021 and 2022:

(1) Represents the aggregate fees billed by Hammerhead's external auditor in the fiscal year ended December 31, 2022 for audit services. Represents the aggregate fees billed by Hammerhead's external auditor in the fiscal year December 31, 2021.

(2) Represents the aggregate fees billed in the fiscal year December 31, 2022 by Hammerhead's external auditor and the aggregate fees billed in the fiscal year for assurance and related services that are reasonably related to the performance of the audit or review of Hammerhead's financial statements (and not reported under the heading Audit Fees) and fees related to the Business Combination.

(3) Represents the aggregate fees billed in each of the last two fiscal years by Hammerhead's external auditor for professional services for tax compliance, tax advice and tax planning. The services comprising the fees disclosed under this category consisted of tax consultations and tax compliance services.

At the meeting, shareholders will be asked to consider and, if thought appropriate, to pass, with or without variation, a special resolution reducing the stated capital of the Common Shares by an aggregate amount of $1,000,000,000, without any payment or distribution to the shareholders and adding the amount of such reduction to the Company's contributed surplus account (the "Reduction of Stated Capital Resolution").

Under the ABCA, the corporate statute governing the Company, a corporation is prohibited from taking certain actions, including making any payments of dividends or any payment to purchase or otherwise acquire shares issued by it, if, among other things, there are reasonable grounds for believing that the realizable value of its assets would, as a result of the payment of dividends or the repurchase of its common shares, be less than the aggregate of its liabilities and stated capital of all classes of its shares. The purpose of reducing the stated capital of the Common Shares is to increase the difference between the realizable value of the Company's assets and the aggregate of the Company's liabilities and the stated capital of the Common Shares, thereby providing the Company with additional flexibility under the ABCA to make payment of dividends or repurchase Common Shares if, as and when the Company Board determines it appropriate to do so. The proposed reduction in stated capital will have no impact on our day-to-day operations and will not alter our financial condition.

The ABCA provides that a corporation shall not reduce its stated capital if there are reasonable grounds for believing that: (i) the corporation is, or would after the reduction be, unable to pay its liabilities as they become due; or (ii) the realizable value of the corporation's assets would thereby be less than the aggregate of its liabilities.

The Company does not have reasonable grounds to believe that: (i) it is, or would after the stated capital reduction contemplated by the Reduction of Stated Capital Resolution be, unable to pay its liabilities as they become due; or (ii) the realizable value of the Company's assets would, as a result of the stated capital reduction contemplated by the Reduction of Stated Capital Resolution, be less than the aggregate of its liabilities.

Canadian Federal Income Tax Considerations with Respect to the Reduction of Stated Capital

This summary is based on the current provisions of the Income Tax Act (Canada) (the "Tax Act"), all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Tax Proposals") and counsel's understanding of the current administrative policies and assessing practices of the Canada Revenue Agency which have been published in writing prior to the date hereof. The summary assumes that all of the Tax Proposals will be implemented in the form proposed, although no assurance in this regard can be given. This summary does not otherwise take into account or anticipate any changes in law or administrative policies and assessing practices, whether by legislative, regulatory, administrative or judicial decision or action, nor does it take into account provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein.

This summary is not applicable to a Shareholder: (a) that is a "financial institution" for the purposes of the "mark-to-market" rules; (b) that is a "specified financial institution"; (c) that reports its "Canadian tax results" in a currency other than Canadian dollars (d) an interest in which is a "tax shelter investment"; or (e) that has entered into a "derivative forward agreement" or a "dividend rental arrangement" in respect of the Common Shares, as each of those terms is defined in the Tax Act. All of the foregoing Shareholders should consult their own tax advisors regarding their particular circumstances.

This summary is not exhaustive of all Canadian federal income tax considerations. Further, this summary is of a general nature only and is not intended to be, nor should it be considered to be, legal or tax advice to any particular Shareholder and no representation is made with respect to the income tax consequences to any particular Shareholder. Accordingly, Shareholders should consult their own tax advisors concerning the application and effect of the income and other taxes of any country, province, territory, state or local tax authority, having regard to their particular circumstances.

The proposed reduction of the stated capital of the Common Shares will not result in any immediate Canadian income tax consequences to a shareholder nor will it affect a Shareholder's adjusted cost base of the Common Shares for purposes of the Tax Act. However, the reduction in the stated capital will reduce the paid-up capital (as defined in the Tax Act) of the Common Shares by an amount equal to the reduction in stated capital. Although the reduction of the stated capital and the corresponding reduction of the paid-up capital of the Common Shares will not have any immediate Canadian income tax consequences, such reduction may have future Canadian federal income tax consequences to a shareholder in certain circumstances. Such circumstances include, but are not limited to, if the Company repurchases any Common Shares (other than Common Shares purchased by the Company in the manner in which shares would normally be purchased by the public in an open market, such as under a normal course issuer bid), if the Company distributes assets to its shareholders or if the Company is wound-up. As a general rule, upon such transactions, a shareholder will be deemed to have received a dividend to the extent that the amount paid or distributed exceeds the paid-up capital of the Common Shares.

The proposed reduction of the stated capital of the Common Shares should not constitute a taxable event for the shareholders of the Company for United States federal income tax purposes. As a result, shareholders generally should not recognize a gain or loss upon the reduction of stated capital. Each shareholder's tax basis in its Common Shares should remain unchanged, and each shareholder's holding period in its Common Shares should include the holding period in the Common Shares held by such shareholder prior to the reduction of stated capital.

At the meeting, shareholders will be asked to consider and, if thought appropriate, to pass the following special resolution, being the Reduction of Stated Capital Resolution:

"BE IT RESOLVED AS A SPECIAL RESOLUTION OF THE SHAREHOLDERS OF HAMMERHEAD ENERGY INC. (THE "COMPANY") THAT:

1. the stated capital account maintained in respect of the Class A common shares of the Company be and is hereby reduced by $1,000,000,000 and the amount of such reduction be and is hereby added to the Company's contributed surplus account, all as more particularly described in the Company's management information circular - proxy statement dated May 1, 2023;

2. any director or officer of the Company is authorized and directed to do all such things and execute all such documents and instruments as may be necessary or desirable to give effect to the foregoing resolution; and

3. notwithstanding that this resolution has been duly passed by the shareholders of the Company, the directors of the Company are hereby authorized and empowered to revoke this resolution, without any further approval of the shareholders of the Company, at any time if such revocation is considered necessary or desirable by the directors."

In order to be passed, the Reduction of Stated Capital Resolution requires the approval of not less than two-thirds of the votes cast thereon by or on behalf of shareholders present in person or represented by proxy at the meeting.

Unless otherwise directed, it is the intention of the persons named in the enclosed form of proxy, if named as proxy, to vote for approval of the foregoing resolution approving the reduction of the Company's stated capital account.

In connection with the Business Combination, the Company adopted the Equity Incentive Award Plan and Share Option Plan in order to facilitate the grant of equity incentive awards and options to directors, employees (including executive officers) and consultants of the Company and certain of its affiliates and to enable the Company to obtain and retain the services of these individuals, which is essential to the Company's long-term success. A third-party compensation consulting advisor was engaged to review executive and director compensation plans including the Equity Incentive Award Plan and Share Option Plan. The Equity Incentive Award Plan and Share Option Plan became effective on February 23, 2023, and were amended and restated on May 1, 2023, and are, along with any grants made thereunder, subject to the ratification by the Company's shareholders at the meeting. The relevant terms of the Equity Incentive Award Plan and Share Option Plan are summarized below, and full copies of the Share Option Plan and Equity Incentive Award Plan are attached hereto as Schedule A and Schedule B, respectively.

At the meeting, shareholders will be asked to consider and approve the Share Option Plan. The Company Board has approved the Share Option Plan. As at the date hereof, the maximum number of Common Shares issuable under the Share Option Plan and all other security based compensation arrangements of the Company, including the Equity Incentive Award Plan, the Legacy Share Award Plan and the Legacy Share Option Plan, may not exceed 10% of the Common Shares outstanding from time to time. As at the date hereof, the Company had no Company Options outstanding under the Share Option Plan, leaving up to 9,097,362 Common Shares available for future grants under the Share Option Plan before taking into account grants under the Equity Incentive Award Plan, the Legacy Share Award Plan and the Legacy Share Option Plan which further reduces the entitlements under the Share Option Plan.

In addition, as at the date hereof, the Company had Legacy Options, Legacy RSUs and Restricted Share Awards outstanding to acquire 7,751,245 Common Shares outstanding under the Equity Incentive Award Plan, the Legacy Share Award Plan and the Legacy Share Option Plan, representing an aggregate of 8.52% of the issued and outstanding Common Shares as at that date, leaving up to 1,346,117 Common Shares, being 1.48% of the issued and outstanding Common Shares, available for future grants under the Share Option Plan and all other security based compensation arrangements, based on the number of Common Shares outstanding as at that date.

The Share Option Plan has been conditionally approved by the TSX, subject to shareholder approval. A summary of the Share Option Plan is provided below and the full plan is attached hereto as Schedule A. A copy of the plan has also been filed on the Company's SEDAR profile at www.sedar.com under the category "Other Securityholder Documents".

Following the Business Combination, the Company implemented the Share Option Plan on February 23, 2023 and amended and restated the Share Option Plan on May 1, 2023 to convert the Share Option Plan from a fixed plan to a 10% rolling plan. Subsequent to its implementation the Company Board has not granted any Company Options.

provided that a Change of Control shall be deemed not to have occurred if a majority of the Company Board, in good faith, determines that a Change of Control was not intended to occur in the particular circumstances in question and any such determination shall be binding and conclusive for all purposes of the Share Option Plan.

"Current Market Price" means, as at any date when the Current Market Price is to be determined, the volume weighted average trading price per Common Share on the TSX, or, if the Common Shares are not listed on the TSX, on any stock exchange in Canada or the United States on which the Common Shares are then listed, for the last five trading days immediately prior to the date of determination, or if the Common Shares are not listed upon any stock exchange in Canada or the United States, the Current Market Price shall be determined by Company Board, acting reasonably.

In the event that Common Shares are not listed and posted for trading on any Exchange, the Fair Market Value shall be the fair market value of Common Shares as determined by Company Board in its sole discretion, acting reasonably and in good faith. If initially determined in United States dollars, the Fair Market Value shall be converted into Canadian dollars at an exchange rate selected and calculated in the manner determined by the Company Board from time to time, acting reasonably and in good faith.

"Insider" has the meaning ascribed thereto in Part I of the TSX Company Manual for the purposes of Section 613 of the TSX Company Manual.

"In-the-Money Value" means the amount by which the Current Market Price on the Pricing Date exceeds the exercise price of the applicable Company Options, multiplied by the number of Common Shares related to the applicable Company Options.

"Pricing Date" means the date the Company receives notice from an Optionee that has elected to exercise a vested Company Option by surrendering such Company Option in exchange for the In-the-Money Value of Company Option in lieu of purchasing the number of Common Shares then issuable on the exercise of the vested Company Option subject to the provisions of the Share Option Plan and if permitted by the Committee.

"Service Provider" means an officer or employee of, or a person or company engaged by, one or more of the entities comprising the HEI Group to provide services to an entity within the HEI Group.

The purpose of the Share Option Plan is to aid in attracting, retaining and motivating the officers, employees and other eligible Service Providers of the HEI Group in the growth and development of the HEI Group by providing them with the opportunity through Company Options to acquire an increased proprietary interest in the Company.

The Share Option Plan is administered by a committee of the Company Board appointed from time to time by the Company Board to administer Share Option Plan or, if no such committee is appointed, the Company Board (the "Committee") pursuant to any rules of procedure that may be fixed by Company Board. To the extent permitted by law, the Committee may delegate or sub-delegate to one or more of its members, to any director or officer of the Company or to one or more agents all or any of the powers conferred on the Committee under the Share Option Plan, and the Committee or any person to whom it has delegated or sub-delegated authority as aforesaid may employ one or more persons to render advice with respect to any responsibility the Committee or such person may have under the Share Option Plan.

For greater certainty and without limiting the discretion conferred on the Committee pursuant to the Share Option Plan, the Committee's decision to approve the grant of a Company Option in any period shall not require the Committee to approve the grant of a Company Option to any Service Provider in any other period; nor shall the Committee's decision with respect to the size or terms and conditions of a Company Option grant in any period require it to approve the grant of a Company Option of the same or similar size or with the same or similar terms and conditions to any Service Provider in any other period. The Committee shall not be precluded from approving the grant of a Company Option to any Service Provider solely because such Service Provider may previously have been granted a Company Option under the Share Option Plan or any other similar compensation arrangement of the Company or a member of the HEI Group. There is no obligation for uniformity of treatment of Service Providers or Optionees under the Share Option Plan. The terms and conditions of Company Options need not be the same with respect to any Optionee or with respect to different Optionees. No Service Provider has any claim or right to be granted a Company Option.

The Committee may from time to time designate officers and employees of, and other eligible Service Providers to, the HEI Group to whom Company Options may be granted and the number of Common Shares to be optioned to each, provided that the number of Common Shares to be optioned shall not exceed the limitations provided.

Notwithstanding any other provision of the Share Option Plan: (a) the number of Common Shares reserved for issuance on exercise of Company Options outstanding under the Share Option Plan, together with the number of Common Shares reserved for issuance under all other security based compensation arrangements of the Company that provide for the issuance of Common Shares, shall not at any time exceed 10% of the Common Shares then issued and outstanding; (b) no one Service Provider may be granted any Company Option which, together with all Company Options then held by such Optionee, would entitle such Optionee to receive a number of Common Shares which is greater than 5% of the outstanding Common Shares, calculated on an undiluted basis; (c) the number of Common Shares (i) issued to Insiders of the Company, within any one year period; and (ii) issuable to Insiders of the Company, at any time; under the Share Option Plan, or when combined with all of the Company's other security based compensation arrangements shall not exceed 10% of the Company's total issued and outstanding Common Shares, respectively. For this purpose, "security based compensation arrangements" has the meaning ascribed thereto in Part VI of the TSX Company Manual.

Company Options that are cancelled, surrendered, terminated or expire prior to the exercise of all or a portion thereof shall result in the Common Shares that were reserved for issuance thereunder being available for a subsequent grant of Company Options pursuant to the Share Option Plan to the extent of any Common Shares issuable thereunder that are not issued under such cancelled, surrendered, terminated or expired Company Options. For greater certainty, any increase in the issued and outstanding Common Shares will result in an increase in the number of Common Shares available under the Share Option Plan.

The Committee may, in its sole discretion, determine: (i) the time during which Company Options shall vest; (ii) the method of vesting; or (iii) that no vesting restriction shall exist. In the absence of any determination by the Committee to the contrary, Company Options will vest and be exercisable as to one-quarter (1/4) of the total number of Common Shares subject to the Company Options on each of the first, second, third and fourth anniversaries of the date of grant (computed in each case rounded down to the nearest whole Common Share with any fractional amount vesting on such fourth anniversary) subject to continued employment or service with the HEI Group. Notwithstanding the foregoing, the Committee may, at its sole discretion at any time or in the option agreement in respect of any Company Options granted, accelerate or provide for the acceleration of vesting of Company Options previously granted.

The exercise price of Company Options granted under the Share Option Plan shall be fixed by the Committee when such Company Options are granted, provided that the exercise price of Company Options shall not be less than such minimum price as may be required by the Exchange, if any, on which the Common Shares are listed at the time of grant.

The period during which a Company Option is exercisable shall, subject to the provisions of the Share Option Plan requiring or permitting the acceleration of rights of exercise or the extension of the exercise period, be such period, not in excess of 15 years, as may be determined from time to time by the Committee, but subject to the rules of any Exchange(s) or other regulatory body having jurisdiction, and in the absence of any determination to the contrary will be five years from the date of grant. Each Company Option shall, among other things, contain provisions to the effect that Company Option shall be personal to the Optionee and shall not be assignable. In addition, unless the Company and an Optionee agree otherwise in an agreement for Company Options or other written agreement (such as an agreement of employment or a retirement agreement), each Company Option shall provide that:

(a) upon the death of the Optionee, the Company Option shall terminate on the earlier of (i) the date determined by the Committee which shall not be more than 12 months from the Cessation Date and, in the absence of any determination to the contrary, 12 months from the Cessation Date and (ii) the Expiry Date of such Company Option;

(b) if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group (other than by reason of death or termination for Cause, voluntary resignation or retirement), the Company Option shall terminate on the earlier of (i) expiry of the period as prescribed by the Committee at the time of grant, following the Cessation Date; and, in the absence of any determination to the contrary, at the later of (A) 90 days following the Cessation Date, and (B) the end of the notice period used for calculating severance to which the Optionee is entitled as a result of the Optionee's cessation as a Service Provider pursuant to a written contract of employment, if any, with an entity in the HEI Group; and (ii) the Expiry Date of such Company Option;

(c) if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group by reason of termination for Cause, the Company Option shall terminate immediately on the Cessation Date (whether notice of such termination occurs verbally or in writing);

(d) if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group by reason of voluntary resignation, effective as of the day that is 14 days after the Cessation Date the Company Option shall terminate; and

(e) if the Optionee shall no longer be an officer of or be in the employ of any of the entities comprising of the HEI Group due to the Optionee's retirement, Company Option shall continue in accordance with its terms and the exercise period shall not be accelerated as a result of the Optionee's retirement;

provided that the number of Common Shares that the Optionee (or his or her heirs or successors) shall be entitled to purchase until such date of termination: (i) shall in the case of death of the Optionee, be all of the Common Shares that may be acquired on exercise of Company Options held by such Optionee (or his or her heirs or successors), whether or not previously vested, and the vesting of all such Company Options shall be accelerated on the Cessation Date; and (ii) in any case other than death or termination for Cause, shall be the number of Common Shares which the Optionee was entitled to purchase on the Cessation Date. In the event of termination for Cause, all of the Common Shares optioned, whether vested or unvested, shall be forfeited.

If any Company Options may not be exercised due to any Black-Out Period at any time within the three-business day period prior to the normal Expiry Date of such Company Options (the "Restricted Options"), the Expiry Date of all Restricted Options shall be extended for a period of seven business days following the end of the Black-Out Period (or such longer period as permitted by the Exchange(s) and approved by the Committee).

Subject to the provisions of Share Option Plan, if permitted by the Committee, an Optionee may elect to exercise a vested Company Option by surrendering such Company Option in exchange for the In-the-Money Value of Company Option in lieu of purchasing the number of Common Shares then issuable on the exercise of the vested Company Option. If the Optionee so elects to exercise Company Option, the Optionee shall be entitled to payment of the In-the-Money Value of the vested Company Option determined as of the Pricing Date. The In-the-Money Value shall be paid in Common Shares issued from treasury with the number of Common Shares issuable being equal to the number obtained by dividing the In-the-Money Value of Company Options in respect of which such election is made by the Current Market Price on the Pricing Date.

An Optionee may make an offer (the "Surrender Offer") to the Company, at any time, for the disposition and surrender by the Optionee to the Company (and the termination thereof) of any of Company Options granted under Share Option Plan for an amount (not to exceed the Fair Market Value of Common Shares less the exercise price of Company Options) specified in the Surrender Offer by the Optionee, and the Company may, but is not obligated to, accept the Surrender Offer, subject to any regulatory approval required. If the Surrender Offer, either as made or as renegotiated, is accepted, Company Options in respect of which the Surrender Offer relates shall be surrendered and deemed to be terminated and cancelled and shall cease to grant the Optionee any further rights thereunder upon payment of the amount of the agreed Surrender Offer by the Company to the Optionee.

In the event: (a) of any change in Common Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise; or (b) that any rights are granted to all or substantially all shareholders to purchase Common Shares at prices substantially below Fair Market Value; or (c) that, as a result of any recapitalization, merger, consolidation or other transaction, Common Shares are converted into or exchangeable for any other shares; then the Company Board may, subject to any required approval by the TSX, make such adjustments to Share Option Plan, to any Company Options and to any agreements for Company Options outstanding under Share Option Plan, and make such amendments to any agreements for Company Options outstanding under Share Option Plan, as the Company Board may, in its sole discretion, consider appropriate in the circumstances to prevent dilution or enlargement of the rights granted to Optionees thereunder and/or to provide for the Optionees to receive and accept such other securities or property in lieu of Common Shares, and the Optionees shall be bound by any such determination.

For greater certainty, and notwithstanding anything to the contrary to the foregoing paragraph, no adjustment shall be made in accordance with respect to the issue of Common Shares being made pursuant to or in connection with (i) any share option plan or share purchase plan, including the Share Option Plan, in force from time to time for existing or proposed officers, directors, employees or Service Providers of the Company, or (ii) the issuance of additional Common Shares pursuant to a public offering or private placement by the Company or a take-over bid or tender offer made by the Company for the securities of another entity.

Except in the case of a transaction that is a Change of Control and to which accelerated vesting and termination of Company Options applies, if the Company enters into any transaction or series of transactions whereby the Company or All or Substantially All of the Assets would become the property of another trust, body corporate, partnership or other person (a "Successor"), whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, prior to or contemporaneously with the consummation of such transaction, the Company and the Successor will execute such instruments and do such things as the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will assume the covenants and obligations of the Company under the Share Option Plan outstanding on consummation of such transaction. Any such Successor shall succeed to, and be substituted for, and may exercise every right and power of the Company under the Share Option Plan with the same effect as though the Successor had been named as the Company therein and thereafter, the Company shall be relieved of all obligations and covenants under the Share Option Plan and the obligation of the Company to the Optionees in respect of Company Options shall terminate and be at an end and the Optionees shall cease to have any further rights in respect thereof including, without limitation, any right to acquire Common Shares upon vesting of Company Options.

Notwithstanding any other provision in Share Option Plan or the terms of any option agreement, upon the consummation of a Change of Control, all issued and outstanding Company Options shall be automatically fully vested and exercisable (whether or not then vested) immediately prior to the time such Change of Control takes place and shall terminate on the 90^th day after the occurrence of such Change of Control, or at such earlier time as may be established by the Company Board, in its absolute discretion, prior to the time such Change of Control takes place.

The Committee may, subject to any required approval of any Exchange, amend or discontinue the Share Option Plan and Company Options granted thereunder at any time without the approval of the shareholders of the Company or any Optionee whose Company Option is amended or terminated, provided that, subject to the terms of the Share Option Plan, no amendment to the Share Option Plan or Company Options granted pursuant to the Share Option Plan may be made without the consent of the Optionee, if it adversely alters or impairs any Company Option previously granted to such Optionee under the Share Option Plan. Without limitation of the foregoing, such amendments include, without limitation: (a) amendments of a "housekeeping nature" nature, including, without limitation, amending the wording of any provision of the Share Option Plan for the purpose of clarifying the meaning of existing provisions or to correct or supplement any provision of the Share Option Plan that is inconsistent with any other provision of the Share Option Plan, correcting grammatical or typographical errors and amending the definitions contained within the Share Option Plan respecting the administration of the Share Option Plan; (b) amending Company Options under the Share Option Plan, including with respect to the Expiry Date (provided that the term of the Company Option does not exceed 15 years from the date the Company Option is granted and that such Company Option is not held by an Insider) and effect of termination of a Optionee's employment or cessation of the Optionee's service; or (c) amendments necessary to comply with applicable law or the requirements of any Exchange. Notwithstanding the foregoing, the Share Option Plan or any outstanding Company Option granted thereunder may not be amended without shareholder approval to:

(a) increase the number of Common Shares reserved for issuance pursuant to Company Options in excess of the limit prescribed in the Share Option Plan;

(b) extend the vesting date of any Company Options granted under the Share Option Plan to an Insider beyond the latest vesting date specified in the option agreement (other than as permitted by the terms and conditions of the Share Option Plan);

(c) extend the Expiry Date of any Company Option granted to an Insider (other than as permitted by the terms and conditions of the Share Option Plan);

(d) permit an Optionee to transfer Company Options to a new beneficial holder other than for estate settlement purposes;

(e) reduce the limitations on Company Options contained in the Share Option Plan;

(f) increase the number of Common Shares that may be issued to Insiders above the restrictions contained in the Share Option Plan; and

Notwithstanding the foregoing, the Committee may amend or terminate the Share Option Plan or any outstanding Company Option granted under the Share Option Plan at any time without the approval of the shareholders of the Company or any Optionee whose Company Option is amended or terminated in order to conform the Share Option Plan or such Company Option, as the case may be, to applicable law or regulation or the requirements of any relevant stock exchange or regulatory authority, whether or not that amendment or termination would affect any accrued rights or adversely alter or impair any Company Option previously granted.

At the meeting, shareholders will be asked to consider the following ordinary resolution approving the Share Option Plan:

"BE IT RESOLVED, as an ordinary resolution of the shareholders of Hammerhead Energy Inc. (the "Company") that:

1. the share option plan (the "Share Option Plan") of the Company in the form attached as Schedule A to the information circular -proxy statement of the Company dated May 1, 2023 (the "Information Circular") is hereby ratified, confirmed and approved;

2. any director or officer of the Company be and is hereby authorized and directed to do such things and to execute and deliver all such instruments, deeds and documents, and any amendments thereto, as may be necessary or advisable in order to give effect to the foregoing resolutions; and

In order to be passed, the foregoing ordinary resolution must be approved by a simple majority of the votes cast by shareholders who vote in person or by proxy at the meeting. The Company Board recommends that shareholders vote FOR the resolution. The management designees intend to vote FOR the resolution, unless a shareholder specifies otherwise in the proxy.

At the meeting, shareholders will be asked to consider and approve the Equity Incentive Award Plan. The Company Board has approved the Equity Incentive Award Plan. As at the date hereof, the maximum number of Common Shares issuable under the Equity Incentive Award Plan and all other security based compensation arrangements of the Company, including the Share Option Plan, the Legacy Share Award Plan and the Legacy Share Option Plan, may not exceed 10% of the Common Shares outstanding from time to time. As at the date hereof, the Company had Restricted Share Awards to acquire 1,945,115 Common Shares outstanding under the Equity Incentive Award Plan, representing 2.14% of the issued and outstanding Common Shares as at that date, leaving up to 7,152,247 Common Shares available for future grants under the Equity Incentive Award Plan before taking into account grants under the Share Option Plan, the Legacy Share Award Plan and the Legacy Share Option Plan which further reduces the entitlements under the Equity Incentive Award Plan.

In addition, as at the date hereof, the Company had Legacy Options, Legacy RSUs and Restricted Share Awards outstanding to acquire 7,751,245 Common Shares outstanding under the Equity Incentive Award Plan, the Legacy Share Award Plan and the Legacy Share Option Plan, representing an aggregate of 8.52% of the issued and outstanding Common Shares as at that date, leaving up to 1,346,117 Common Shares, being 1.48% of the issued and outstanding Common Shares, available for future grants under the Equity Incentive Award Plan and all other security based compensation arrangements, based on the number of Common Shares outstanding as at that date.

The Equity Incentive Award Plan has been conditionally approved by the TSX, subject to shareholder approval. A summary of the Equity Incentive Award Plan is provided below and the full plan is attached hereto as Schedule B. A copy of the plan has also been filed on the Company's SEDAR profile at www.sedar.com under the category "Other Securityholder Documents".

Following the Business Combination, the Company implemented the Equity Incentive Award Plan on February 23, 2023 and amended and restated the Equity Incentive Award Plan on May 1, 2023 to convert the Equity Incentive Award Plan from a fixed plan to a 10% rolling plan. Subsequent to its implementation the Company Board has granted a total of 1,949,700 Restricted Share Awards and prior to the date hereof, 4,585 of those Restricted Share Awards were forfeited due to an employee leaving the Company, leaving a total of 1,945,115 Restricted Share Awards outstanding. Such 1,945,115 Restricted Share Awards will vest at various points through 2024, 2025 and 2026. Of the 1,945,115 Restricted Share Awards granted, 466,500 Restricted Share Awards have been granted to directors of the Company, 460,100 Restricted Share Awards have been granted to officers of the Company and the remaining 1,018,515 Restricted Share Awards were granted to employees of the Company. These 1,945,115 Restricted Share Awards cannot be exercised until such time the Company has obtained shareholder approval of the Equity Incentive Award Plan and that the 1,945,115 Restricted Share Awards granted have been ratified by the shareholders of the Company. These 1,945,115 Restricted Share Awards will be cancelled if shareholders do not ratify the Equity Incentive Award Plan and the grants made thereunder.

The principal purposes of the Equity Incentive Award Plan are to: (a) aid in attracting, retaining and motivating qualified Service Providers of the HEI Group in the growth and development of the HEI Group by providing them with the opportunity through Awards to acquire an increased proprietary interest in the Company; (b) more closely align such Service Providers' interests with those of the Company's shareholders; (c) focus such Service Providers on operating and financial performance and long-term shareholder value; and (d) motivate and reward for such Service Providers' performance and contributions to the Company's long-term success.

The Equity Incentive Award Plan shall be administered by the Compensation Committee of the Company Board (the "Committee"), provided that the Company Board shall have the authority to appoint itself or another committee of the Company Board to administer the Equity Incentive Award Plan. In the event that the Company Board appoints itself or another committee of the Company Board to administer the Equity Incentive Award Plan, all references in the Equity Incentive Award Plan to the Committee will be deemed to be references to the Company Board or such other committee of the Company Board, as applicable.

To the extent permitted by law, the Committee may delegate or sub-delegate to one or more of its members, to any director or officer of the Company or to one or more agents all or any of the powers conferred on the Committee under the Equity Incentive Award Plan, and the Committee or any person to whom it has delegated or sub-delegated authority as aforesaid may employ one or more persons to render advice with respect to any responsibility the Committee or such person may have under the Equity Incentive Award Plan.

For greater certainty and without limiting the discretion conferred on the Committee pursuant to the Equity Incentive Award Plan, the Committee's decision to approve the grant of an Award in any period shall not require the Committee to approve the grant of an Award to any Service Provider in any other period; nor shall the Committee's decision with respect to the size or terms and conditions of an Award in any period require it to approve the grant of an Award of the same or similar size or with the same or similar terms and conditions to any Service Provider in any other period. The Committee shall not be precluded from approving the grant of an Award to any Service Provider solely because such Service Provider may previously have been granted an Award under the Equity Incentive Award Plan or any other similar compensation arrangement of the Company or a member of the HEI Group. There is no obligation for uniformity of treatment of Service Providers or Participants under the Equity Incentive Award Plan. The terms and conditions of Awards need not be the same with respect to any Participant or with respect to different Participants. No Service Provider has any claim or right to be granted an Award.

Each Award granted under the Equity Incentive Award Plan shall be subject to the terms and conditions of the Equity Incentive Award Plan and evidenced by a written agreement between the Company and the Participant (an "Incentive Award Agreement" in the case of an Incentive Award and a "Share Award Agreement" in the case of a Share Award) which agreement shall comply with, and be subject to, the requirements of the Exchange.

At the discretion of the Company Board, the Equity Incentive Award Plan provides for cumulative adjustments to the number of Shares to be issued pursuant to Awards on each date that dividends are paid on the Shares by an amount equal to a fraction having as its numerator the amount of the dividend per Share and having as its denominator the price, expressed as an amount per Share, paid by participants in the Company's Dividend Reinvestment Plan (as defined in the Plan), if any, to reinvest their dividends in additional Shares on the applicable dividend payment date, provided that if the Company has suspended the operation of such plan or does not have such a plan, then the reinvestment price shall be equal to the Fair Market Value of the Shares on the trading day immediately preceding the dividend payment date. Under the Equity Incentive Award Plan, in the case of a non-cash dividend, including Shares or other securities or property, the Committee will, in its sole discretion and subject to the approval of the Exchange, determine whether or not such non-cash dividend will be provided to the Participant and, if so provided, the form in which it shall be provided.

Pursuant to the terms of the Equity Incentive Award Plan, the Restricted Awards and the Performance Awards shall vest at the end of their three-year terms, respectively.

Notwithstanding any other provisions of the Equity Incentive Award Plan, the aggregate number of Common Shares reserved for issuance from time to time pursuant to Awards granted and outstanding thereunder at any time, and together with the aggregate number of Shares reserved for issuance under all other security based compensation arrangements of the Company that provide for the issuance of Shares, shall not at any time exceed 10% of the Shares then issued and outstanding.

If any Award granted under the Equity Incentive Award Plan shall expire, terminate or be cancelled for any reason without the Shares issuable thereunder having been issued in full, any unissued Shares to which such Award relates shall be available for the purposes of the granting of further Awards under the Equity Incentive Award Plan. For greater certainty, any increase in the issued and outstanding Shares will result in an increase in the number of Shares available under this Plan.

The aggregate number of Shares issuable pursuant to Awards granted to any single Service Provider shall not exceed 5% of the issued and outstanding Shares, calculated on an undiluted basis and assuming all Awards will be settled in Shares. In addition: (i) the number of Shares issuable to insiders at any time, under all security based compensation arrangements of the Company, shall not exceed 10% of the issued and outstanding Shares; and (ii) the number of Shares issued to insiders, within any one year period, under all security based compensation arrangements of the Company, shall not exceed 10% of the issued and outstanding Shares.

The Company may grant Restricted Awards and Performance Awards that, at the option of the Company, either: (a) entitle the holder on vesting to be issued the number of Shares designated in the Restricted Award or Performance Award, as applicable; or (b) entitle the holder on vesting to receive an amount equal to the value of the Restricted Award or Performance Award, as applicable, (being an amount equal to the number of Awards multiplied by the Fair Market Value of the Shares), which amount will in the sole and absolute discretion of the Company (and without the consent of the Participant), be settled in (i) cash, (ii) Shares acquired by the Company on the Exchange, (iii) Shares issued from the treasury of the Company, or (iv) any combination of the foregoing. In the case of Performance Awards, the number of Shares issuable or the value of the Award, as applicable, is multiplied by a payout multiplier. The payout multiplier is determined by the Committee based on an assessment of the achievement of pre-defined corporate performance measures in respect of the applicable period as determined by the Committee. The payout multiplier may not be less than 0% or more than 200%. The Awards issuable pursuant to the Equity Incentive Award Plan are not assignable.

A Participant may elect to exercise Share Awards at any time and from time to time from and including the day the Vesting Date in respect of such Share Awards occurs until the Expiry Date of such Share Awards, by delivering to the Company a duly completed and executed Exercise Notice; provided, that no Participant who is resident in the United States may exercise Share Awards unless the Shares issuable by the Company upon such exercise are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act. If any Share Award may not be exercised due to any Black-Out Period at any time within the three-business day period prior to the Expiry Date of such Share Award the Expiry Date of all such Share Awards shall be extended for a period of seven business days following the end of the Black-Out Period (or such longer period as permitted by the Exchange(s) and approved by the Committee).

If a Participant is prohibited from trading in securities of the Company as a result of the imposition by the Company of a trading black-out (a "Black-out Period") and the issue or payment date of the Shares underlying an Award held by such Participant falls within the Black-out Period, then the issue or payment date of such Shares shall be extended to the date that is seven business days following the end of such Black-out Period; provided that if the expiry date of the Awards would occur as a result of such extension, the Awards will be settled on the expiry date in cash rather than Shares.

If the Company enters into any transaction or series of transactions, other than a transaction that is a Change of Control and whereby the Company or All or Substantially All of the Assets would become the property of any other trust, body corporate, partnership or other person (a "Successor") whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, then prior to or contemporaneously with the consummation of such transaction: (a) the Company and the Successor will execute such instruments and do such things as the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will have assumed the covenants and obligations of the Company under the Equity Incentive Award Plan and the Award Agreements outstanding on consummation of such transaction and such Successor shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Equity Incentive Award Plan and such Award Agreements with the same effect as though the Successor had been named as the Company in the Equity Incentive Award Plan and therein and thereafter, the Company shall be relieved of all obligations and covenants under the Equity Incentive Award Plan and such Award Agreements and the obligation of the Company to the Participants in respect of the Awards shall terminate and be at an end and the Participants shall cease to have any further rights in respect thereof including, without limitation, any right to acquire or receive Shares on the Vesting Date(s) applicable to such Awards; or (b) if the Awards (and the covenants and obligations of the Company under the Equity Incentive Award Plan and the Award Agreements outstanding on consummation of such transaction) are not so assumed by the Successor, then the Vesting Date for all Shares awarded pursuant to such Awards that have not yet been issued as of such time shall be the date which is immediately prior to the date upon which the transaction is consummated.

In the event (a) of any change in the Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise; (b) that any rights are granted to all Shareholders to purchase Shares at prices substantially below Fair Market Value; or (c) that, as a result of any recapitalization, merger, consolidation or other transaction, the Shares are converted into or exchangeable for any other securities, then, in any such case, the Company Board may, subject to any required approval of the Exchange, make such adjustments to the Equity Incentive Award Plan, to any Awards and to any Award Agreements outstanding under the Equity Incentive Award Plan as the Company Board may, in its sole discretion, consider appropriate in the circumstances to prevent dilution or enlargement of the rights granted to Participants thereunder.

Unless otherwise determined by the Committee or unless otherwise provided in an Award Agreement pertaining to a particular Award or any written employment or consulting agreement governing a Participant's role as a Service Provider, the following provisions shall apply in the event that a Participant ceases to be a Service Provider:

(a) Death - If a Participant ceases to be a Service Provider as a result of the Participant's death, the Vesting Date for all Incentive Awards awarded to such Participant under any outstanding Incentive Award Agreements and for all Shares awarded to such Participant under any outstanding Award Agreements shall be accelerated to the Cessation Date, provided that the Committee, taking into consideration the performance of such Participant and the performance of the Company since the date of grant of the Award(s), may determine in its sole discretion the payout multiplier to be applied to any Performance Awards held by the Participant. The Expiry Date of any vested or unvested Share Awards held by the Participant at the date of death, which have not yet been subject to an Exercise Notice and subsequent settlement of the Share Award, shall be amended to the earlier of (i) one year after the Cessation Date, and (ii) the Expiry Date of such Share Award.

(b) Termination for Cause - If a Participant ceases to be a Service Provider as a result of termination for cause, effective as of the Cessation Date all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, and whether (A) vested and unexercised or unsettled or (B) unvested, shall be immediately terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

(c) Voluntary Resignation - If a Participant ceases to be a Service Provider as a result of a voluntary resignation, effective as of the day that is 14 days after the Cessation Date, all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, and whether (A) vested and unexercised or unsettled or (B) unvested, shall be terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

(d) Retirement - If a Participant ceases to be a Service Provider as a result of the Participant's retirement, all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, shall continue in accordance with their terms and the Expiry Date shall not be accelerated as a result of such retirement.

(e) Other Termination - If a Participant ceases to be a Service Provider for any reason other than as provided for in (i), (ii), (iii) and (iv) above, effective as of the date that is the later of (A) 90 days after the Cessation Date, and (B) the end of the notice period used for calculating severance to which the Participant is entitled as a result of the Participant's cessation as a Service Provider pursuant to a written contract of employment, if any, with an entity in the HEI Group, and notwithstanding any other severance entitlements or entitlement to notice or compensation in lieu thereof, all then outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, shall be terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

If a Participant fails to acknowledge an Award by acceptance of the Award Agreement within the time specified by the Committee, the Company reserves the right to revoke the Award. Participation in the Equity Incentive Award Plan by any Participant shall be construed as irrevocable acceptance by the Participant of the terms and conditions set out in the Equity Incentive Award Plan and all rules and procedures adopted thereunder and as amended from time to time.

The Equity Incentive Award Plan and any Awards granted pursuant to the Equity Incentive Award Plan may, subject to any required approval of the Exchange, be amended, modified or terminated by the Company Board without the approval of Shareholders. Without limitation of the foregoing, such amendments include, without limitation: (a) amendments of a "housekeeping nature", including, without limitation, amending the wording of any provision of the Equity Incentive Award Plan for the purpose of clarifying the meaning of existing provisions or to correct or supplement any provision of the Equity Incentive Award Plan that is inconsistent with any other provision of the Equity Incentive Award Plan, correcting grammatical or typographical errors and amending the definitions contained within the Equity Incentive Award Plan respecting the administration of the Equity Incentive Award Plan; (b) amending Awards under the Equity Incentive Award Plan, including with respect to the Expiry Date (provided that the term of the Award does not exceed 10 years from the date the Award is granted and that such Award is not held by an insider), vesting period, and effect of termination of a Participant's employment or cessation of the Participant's service; (c) accelerating vesting; or (d) amendments necessary to comply with applicable law or the requirements of any Exchange on which the Shares are listed. Notwithstanding the foregoing, the Equity Incentive Award Plan or any Award may not be amended without Shareholder approval to:

(a) increase the number of Shares reserved for issuance pursuant to Awards in excess of the limit prescribed in the Equity Incentive Award Plan;

(b) extend the Vesting Date of any Awards issued under the Equity Incentive Award Plan to an insider beyond the latest Vesting Date specified in the Award Agreement (other than as permitted by the terms and conditions of the Equity Incentive Award Plan);

(c) extend the Expiry Date of any Award granted to an insider (other than as permitted by the terms and conditions of the Equity Incentive Award Plan);

(d) permit a Participant to transfer Awards to a new beneficial holder other than for estate settlement purposes;

(e) reduce the limitations on Awards contained in the Equity Incentive Award Plan;

(f) increase the number of Shares that may be issued to Insiders above the restrictions contained in the Equity Incentive Award Plan; and

(g) change the Equity Incentive Award Plan to modify or delete any of (a) through (f) above.

In addition, no amendment to the Equity Incentive Award Plan or any Awards granted pursuant to the Equity Incentive Award Plan may be made without the consent of a Participant if it adversely alters or impairs the rights of such Participant in respect of any Award previously granted to such Participant under the Equity Incentive Award Plan.

At the meeting, shareholders will be asked to consider the following ordinary resolution approving the Equity Incentive Award Plan:

"BE IT RESOLVED, as an ordinary resolution of the shareholders of Hammerhead Energy Inc. (the "Company") that:

1. the equity incentive award plan (the "Equity Incentive Award Plan") of the Company in the form attached as Schedule B to the information circular -proxy statement of the Company dated May 1, 2023 (the "Information Circular") is hereby ratified, confirmed and approved;

2. the grants of awards which are described in the Information Circular, be and are hereby ratified, confirmed and approved;

3. any director or officer of the Company be and is hereby authorized and directed to do such things and to execute and deliver all such instruments, deeds and documents, and any amendments thereto, as may be necessary or advisable in order to give effect to the foregoing resolutions; and

4. notwithstanding that this resolution has been duly passed by the shareholders of the Company, the directors of the Company are hereby authorized and empowered to revoke this resolution, without any further approval of the shareholders of the Company, at any time if such revocation is considered necessary or desirable by the directors."

The Company did not pay any compensation or provide any benefits for the fiscal year ended December 31, 2022, to the non-management directors as the Company was formed by way of amalgamation on February 22, 2023, pursuant to the Business Combination.

The Company has approved annual retainers of $140,000 and $180,000 for the non-management directors and the Chair of the Company Board, respectively, payable in cash or a combination of cash and share awards.

The Common Shares and Warrants are listed on the NASDAQ under the ticker symbols "HHRS" and "HHRSW," respectively, and on the TSX under the ticker symbols "HHRS" and "HHRS.WT," respectively.

As a result, the Company adheres to the rules of the NASDAQ and applicable Canadian securities laws in determining whether a director is independent. The listing standards of the NASDAQ generally define an "independent director" as a person, other than an executive officer of a company or any other individual having a relationship which, in the opinion of the issuer's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Under NI 58-101, a director is considered to be independent if he or she is independent within the meaning of Section 1.4 of NI 52-110. Pursuant to NI 52-110, an independent director is a director who is free from any direct or indirect material relationship with the Company which could, in the view of the Company Board, be reasonably expected to interfere with the exercise of such director's independent judgement. The Company Board has determined that A. Stewart Hanlon, J. Paul Charron, James AC McDermott, and Bryan Begley are considered independent directors. The Company Board has determined Scott Sobie, Michael Kohut, Jesal Shah, and Robert Tichio are not independent based on their relationships with the Company and the Riverstone Parties, as applicable. The independent directors of the Company Board will hold regularly scheduled meetings at which non-independent directors and members of management are not in attendance.

The following directors are presently directors of other issuers that are reporting issuers (or the equivalent):

The primary responsibility of the Company Board is to appoint competent management and to oversee the management of the Company with a view to maximize shareholder value and ensure corporate conduct in an ethical and legal manner through an appropriate system of corporate governance and internal controls. Subject to the provisions of the ABCA, the Company Board may delegate certain of those powers and authority that the directors of the Company, or independent directors, as applicable, deemed necessary or desirable to affect the actual administration of the duties of the Company Board. The Company Board's duties are set out in the Company Board Mandate which is found in Schedule C attached hereto and on our website at www.hhres.com.

The Company Board, in part, performs its responsibilities through its four committees: the Audit Committee; the Governance and ESG Committee; the Compensation Committee and the Reserves Committee. Each of the four committees has their own mandate as described below.

It is the responsibility of the Company Board to provide an orientation program for new directors and ongoing educational opportunities for all directors. The Company Board will from time to time arrange for presentations by key personnel or qualified outside consultants concerning topics relating to the Company's business, changes to the Company's legal and regulatory framework and corporate and Company Board governance. The Company Board also encourages directors to attend external continuing education programs designed for directors of public companies. In addition to pursuing individual educational initiatives, members of the Company Board are provided with quarterly operational and financial reports summarizing the Company's performance. The Company also provides opportunities to have meetings and discussions with management as needed to address requests or questions a Company Board member may have.

The Company Board consists of highly skilled and experienced individuals with strong industry knowledge. Please see "Biographies of Our Directors" for more information on each Company Board member and their curriculum vitae.

The Company has adopted a Code of Conduct and has posted such Code of Conduct, and intends to post any amendments to or any waivers from a provision of its Code of Conduct, on its website, and also intends to disclose any amendments to or waivers of certain provisions of its Code of Conduct in a manner consistent with NI 58-101 and the applicable rules or regulations of the SEC and the NASDAQ. All employees of the Company are required to acknowledge compliance with the code of business conduct and all related policies when they are hired and again on an annual basis. In addition, the Company has implemented a whistleblower policy throughout the Company and the Company will monitor compliance with the Code of Conduct. Any effort to retaliate against any person making a complaint in good faith under the Code of Conduct is strictly prohibited and will be reported immediately to the Chair of the Company Board.

In accordance with the ABCA, directors who are a party to, or are a director or an officer of a person who is a party to, a material contract or material transaction or a proposed material contract or proposed material transaction, are required to disclose the nature and extent of their interest and not vote on any resolution to approve the contract or transaction.

The Company has adopted an insider trading policy which prohibits its executives, other employees, and directors from: (i) trading in its securities while in possession of material undisclosed information about the Company; and (ii) entering into certain derivative-based transactions that involve, directly or indirectly, securities of the Company, during a restricted period.

The Company recognizes the importance and benefit of having the Company Board and senior management composed of highly talented and experienced individuals having regard to the need to foster and promote diversity among Company Board members and senior management with respect to attributes such as gender, ethnicity and other factors. In support of this goal, the Governance and ESG Committee will, when identifying candidates to nominate for election to the Company Board or appoint as senior management or in its review of senior management succession planning and talent management:

An individual's qualifications are paramount in identifying a Company Board nominee. Consideration for nominations is made based on the needs of the Company Board at the applicable time and the alignment of the individual's talent, functional expertise, experience and personal skills. Currently, the Company's Diversity Policy does not provide for targets for the number of women on the Company Board or in executive officer positions. This does not preclude the Company from electing or promoting women. Currently 30% of the Company's employees are women; of which 73.0% are a designated professional or hold a leadership role. The Company does not have any women serving on the Company Board and has one woman in an executive officer position, representing approximately 16.7% of the Company's executive officer positions.

Set forth below is information with respect to each of the current committees of the Company Board, including current membership and a brief description of their Company Board approved mandate which outlines the roles and responsibilities of the committee. The full text of the mandate of each committee is available on our website at www.hhres.com.

(1) The Company Board has determined that each such director is independent under the Listing Rules, NI 52-110 and under Rule 10A-3 of the Exchange Act. A.

The following disclosure relates to the current executive compensation practices of the Company for the current fiscal year.

The Legacy Plans are in substantially the same form as the Hammerhead Share Option Plan and Hammerhead Share Award Plan, subject to such changes to provide for the Business Combination and such changes as required by applicable laws and stock exchange rules. Under the terms of the Legacy Plans and the policies of the TSX, the Company is not entitled to make any further grants of Legacy Options or Legacy RSUs under the Legacy Plans.

All Share Awards issued pursuant the Legacy Share Award Plan shall be fully vested and exercisable on issuance and shall not be subject to any vesting restrictions.

Notwithstanding any other provision of the Legacy Share Award Plan, the maximum number of Shares issuable pursuant to outstanding Share Awards at any time shall be limited to 5,329,938, subject to adjustment for Dividend Equivalents, if any.

Share Awards that are cancelled, surrendered, terminated or that expire prior to exercise thereof shall not in such Shares being available to be issued in respect of a subsequent grant of Share Awards pursuant to the Legacy Share Award Plan.

The term during which a Share Award may be outstanding shall, subject to the provisions of the Legacy Share Award Plan requiring or permitting the acceleration or the extension of the term, be such period as may be determined from time to time by the Company Board or the Committee, but subject to the rules of any stock exchange or other regulatory body having jurisdiction.

In addition, unless otherwise determined by the Company Board or the Committee, or unless the Company and a Participant agree otherwise in a Share Award Agreement or other written agreement (including an employment or consulting agreement), each Share Award shall provide that if a Participant shall cease to be a director, officer of or be in the employ of, or a consultant or other Service Provider to, any of the entities comprising the HEI Group for any reason whatsoever (other than death or retirement) including, without limitation, resignation or involuntary termination (with or without cause), as determined by the Company Board in its sole discretion, before all of the Share Awards credited to the Participant's Account have been Exercised or are forfeited pursuant to any other provision hereof: (a) such Participant shall cease to be a Participant as of the Cessation Date; (b) any underlying Shares corresponding to any Share Awards that have not been Exercised on the Cessation Date shall be Exercised by the former Participant within 90 days of the Cessation Date in accordance with the Legacy Share Award Plan; and (c) the former Participant shall not be entitled to any further distribution of Shares or any payment from the Legacy Share Award Plan.

Notwithstanding the preceding paragraph or anything else contained in the Legacy Share Award Plan to the contrary, unless otherwise determined by the Company Board or the Committee, or unless the Company and a Participant agree otherwise in a Share Award Agreement or other written agreement (including an employment or consulting agreement), if a Participant shall cease to be an officer of or be in the employ of, or a consultant or other Service Provider to, any of the entities comprising the HEI Group due to the death of the Participant, any underlying Shares corresponding to any Share Awards that have not been exercised shall be exercised by the legal representative of the deceased former Participant's estate within 12 months of the Cessation Date in accordance with the Legacy Share Award Plan.

The Company shall, as soon as practicable after the exercise of any Share Awards granted under the Legacy Share Award Plan, issue from treasury to the Participant the number of Shares required to be delivered upon the exercise of such Participant's Share Awards; provided, however, that, with the consent of the Participant, in lieu of issuing Shares from treasury the Company may satisfy its obligation to deliver Shares to the Participant upon the exercise of such Participant's Share Awards by delivering Shares from the Hammerhead Employee Benefit Trust. The Company shall register and deliver certificates for such Shares to the Participant by first class insured mail, unless the Company shall have received alternative instructions from the Participant acceptable to the Company for the registration and/or delivery of the certificates. The Participant shall exercise any Share Awards by: (i) delivering to the Company a notice of exercise in writing, in such form as may be approved by the Company Board or the Committee from time to time, signed by the Participant and stating the Participant's intention to exercise a particular Share Award together with payment of the exercise price of C$0.16 per Share Award so exercised; and (ii) if the Share Awards are being exercised by the legal representative of a deceased former Participant's estate, providing the Company with satisfactory evidence of the Participant's death. Upon receipt of the exercise notice, aggregate exercise price and evidence of the Participant's death (if applicable), the Company shall cause the Shares in respect of which the Share Award has been Exercised to be issued or delivered as provided above.

A Participant may make an offer (the "Surrender Offer") to the Company, at any time, for the disposition and surrender by the Participant to the Company (and the termination thereof) of any of the Share Awards granted thereunder for an amount (not to exceed the Fair Market Value of the Shares less the exercise price of the Share Award) specified in the Surrender Offer by the Participant, and the Company may, but is not obligated to, accept the Surrender Offer, subject to any regulatory approval required. If the Surrender Offer, either as made or as renegotiated, is accepted, the Share Awards in respect of which the Surrender Offer relates shall be surrendered and deemed to be terminated and cancelled and shall cease to grant the Participant any further rights thereunder upon payment of the amount (less all taxes and other amounts required by law to by withheld by the Company) of the Surrender Offer agreed to by the Company and the Participant.

In the event: (a) of any change in the Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise; or (b) that any rights are granted to all or substantially all shareholders to purchase Shares at prices substantially below Fair Market Value; or (c) that, as a result of any recapitalization, merger, consolidation or other transaction, the Shares are converted into or exchangeable for any other securities or property; then the Company Board may make such adjustments to the Legacy Share Award Plan, to any Share Awards and to any Share Award Agreements outstanding under the Legacy Share Award Plan as the Company Board may, in its sole discretion, consider appropriate in the circumstances to prevent dilution or enlargement of the rights granted to Participants thereunder and/or to provide for the Participants to receive and accept such other securities or property in lieu of Shares, and the Participants shall be bound by any such determination.

No adjustment shall be made with respect to the issue of Shares being made pursuant to or in connection with: (a) any share option plan or share purchase plan, including the Legacy Share Award Plan, in force from time to time for existing or proposed officers, directors, employees or Service Providers of the Company; (b) the issuance of additional Shares pursuant to a public offering or private placement by the Company or a take-over bid, tender offer or other acquisition made by the Company for the securities of another entity; or (c) upon Exercise or vesting of any convertible securities of the Company outstanding from time to time.

Except in the case of a transaction that is a Change of Control and to which the paragraph below applies, if the Company enters into any transaction or series of transactions whereby the Company or All or Substantially All of the Assets would become the property of any other trust, body corporate, partnership or other person (a "Successor"), whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, prior to or contemporaneously with the consummation of such transaction the Company and the Successor will execute such instruments and do such things as the Company Board or the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will assume the covenants and obligations of the Company under the Legacy Share Award Plan and the Share Award Agreements outstanding on consummation of such transaction. Any such Successor shall succeed to, and be substituted for, and may exercise every right and power of the Company under the Legacy Share Award Plan and Share Award Agreements with the same effect as though the Successor had been named as the Company in the Legacy Share Award Plan and therein and thereafter, the Company shall be relieved of all obligations and covenants under the Legacy Share Award Plan and such Share Award Agreements and the obligation of the Company to the Participants in respect of the Share Awards shall terminate and be at an end and the Participants shall cease to have any further rights in respect thereof including, without limitation, any right to acquire Shares upon the Exercise of the Share Awards.

Notwithstanding any other provision in the Legacy Share Award Plan but subject to any provision to the contrary contained in a Share Award Agreement or other written agreement (such as an agreement of employment) between the Company and a Participant, if there takes place a Change of Control, all issued and outstanding Share Awards shall terminate on the 90th day after the occurrence of such Change of Control or at such earlier time as may be established by the Company Board or the Committee, in its absolute discretion, prior to the time such Change of Control takes place.

The Company Board may amend or discontinue the Legacy Share Award Plan and any Share Award granted thereunder at any time without the approval of the shareholders of the Company or any Participant whose Share Award is amended or terminated, provided that no amendment to the Equity Incentive Award Plan or Share Awards granted pursuant to the Equity Incentive Award Plan may be made without the consent of the Participant, if it adversely alters or impairs any Share Award previously granted to such Participant under the Equity Incentive Award Plan.

The Company Board may, subject to any required approval of any Exchange, amend or discontinue the Legacy Share Award Plan and any Share Award granted thereunder at any time without the approval of the shareholders of the Company or any Participant whose Share Award is amended or terminated, provided that, no amendment to the Legacy Share Award Plan or Share Awards granted pursuant to the Legacy Share Award Plan may be made without the consent of the Participant, if it adversely alters or impairs any Share Award previously granted to such Participant under the Legacy Share Award Plan. Without limitation of the foregoing, such amendments include, without limitation: (a) amendments of a "housekeeping nature" nature, including, without limitation, amending the wording of any provision of the Legacy Share Award Plan for the purpose of clarifying the meaning of existing provisions or to correct or supplement any provision of the Legacy Share Award Plan that is inconsistent with any other provision of the Legacy Share Award Plan, correcting grammatical or typographical errors and amending the definitions contained within the Legacy Share Award Plan respecting the administration of the Legacy Share Award Plan; (b) amending Share Awards under the Legacy Share Award Plan , including with respect to the expiry date (provided that such Share Award is not held by an Insider) and effect of termination of a Participant's employment or cessation of the Participant's service; or (c) amendments necessary to comply with applicable law or the requirements of any Exchange. Notwithstanding the foregoing, the Legacy Share Award Plan or any outstanding Share Award granted thereunder may not be amended without shareholder approval to:

(a) permit Share Awards to be issued other than pursuant to the Plan of Arrangement;

(a) increase the number of Shares reserved for issuance pursuant to Share Awards in excess of the limit prescribed in the Legacy Share Award Plan;

(b) extend the expiry date of any Share Award granted to an Insider (other than as permitted by the terms and conditions of the Legacy Share Award Plan);

(d) reduce the limitations on Share Awards contained in the Legacy Share Award Plan; and

Notwithstanding the foregoing, the Company Board may amend or terminate the Legacy Share Award Plan or any outstanding Share Award granted thereunder at any time without the approval of the shareholders of the Company or any Participant whose Share Award is amended or terminated, in order to conform the Legacy Share Award Plan or such Share Award, as the case may be, to applicable law or regulation or the requirements of any relevant stock exchange or regulatory authority, whether or not that amendment or termination would affect any accrued rights or adversely alter or impair any Share Award previously granted.

Without limiting the foregoing, the Company Board may correct any defect or supply any omission or reconcile any inconsistency in the Equity Incentive Award Plan in the manner and to the extent deemed necessary or desirable, may establish, amend, and rescind any rules and regulations relating to the Legacy Share Award Plan, and may make such determinations as it deems necessary or desirable for the administration of the Legacy Share Award Plan.

On termination of the Legacy Share Award Plan, any outstanding Share Awards under the Legacy Share Award Plan shall immediately vest and the number of Shares corresponding to such Share Awards shall be delivered to the Participants in accordance with and upon compliance with the Legacy Share Award Plan. The Legacy Share Award Plan will finally cease to operate for all purposes when: (i) the last remaining Participant receives delivery of all Shares corresponding to all Share Awards credited to the Participant's Account; or (ii) all unexercised Share Awards expire in accordance with the terms of the Legacy Share Award Plan.

In the event that Common Shares are not listed and posted for trading on any stock exchange, the Fair Market Value shall be the fair market value of Common Shares as determined by the Company Board in its sole discretion.

"HEI Group" means, collectively, the Company, any entity that is a Subsidiary of the Company from time to time, including, without limitation, any entity designated by the Company Board from time to time as a member of the HEI Group for the purposes of the Legacy Share Option Plan (and, for greater certainty, including any successor entity of any of the aforementioned entities) provided, however, that with respect to any Optionee that is subject to United States federal income taxation, such entity is a "service recipient" within the meaning of Code Section 409A with respect to such Optionee.

The Legacy Share Option Plan is administered by a committee of the Company Board appointed from time to time by the Company Board to administer the Legacy Share Option Plan or, if no such committee is appointed, the Company Board (the "Committee") pursuant to any rules of procedure that may be fixed by the Company Board.

Subject to the Plan of Arrangement, the Committee may from time to time designate officers, directors and employees of, and other eligible Service Providers to, the HEI Group to whom Legacy Options may be granted and the number of Common Shares to be optioned to each, provided that the number of Common Shares to be optioned shall not exceed the limitations provided in the Legacy Share Option Plan.

The period during which a Legacy Option is exercisable shall, subject to the provisions of the Legacy Share Option Plan requiring or permitting the acceleration or extension of the exercise period, be such period, not in excess of 15 years, as may be determined from time to time by the Committee, but subject to the rules of any stock exchange or other regulatory body having jurisdiction, and in the absence of any determination to the contrary will be five years from the date of grant. Each Legacy Option shall, among other things, contain provisions to the effect that Legacy Option shall be personal to the Optionee and shall not be assignable. In addition, unless the Company and an Optionee agree otherwise in an agreement for Legacy Options or other written agreement (such as an agreement of employment or a retirement agreement), each Legacy Option shall provide that:

(c) if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group by reason of termination for cause, the Legacy Option shall terminate immediately on such termination for cause (whether notice of such termination occurs verbally or in writing); and

(d) if the Optionee shall no longer be an officer of or be in the employ of any of the entities comprising of the HEI Group due to the Optionee's retirement, the Legacy Option shall terminate 12 months following the date that the Optionee ceases to be an officer of or be in the employ of any of the entities in the HEI Group;

provided that the number of Common Shares that the Optionee (or his or her heirs or successors) shall be entitled to purchase until such date of termination: (i) shall in the case of death of the Optionee, be all of the Common Shares that may be acquired on exercise of Legacy Options held by such Optionee (or his or her heirs or successors), whether or not previously vested, and the vesting of all such Legacy Options shall be accelerated on the date of death for such purpose; and (ii) in any case other than death or termination for cause, shall be the number of Common Shares which the Optionee was entitled to purchase on the date the Optionee ceased to be an officer, director, employee, consultant or other Service Provider, as the case may be. In the event of termination for cause, all of the Common Shares optioned, whether vested or unvested, shall be forfeited.

If any Legacy Options may not be exercised due to any Black-Out Period at any time within the three-business day period prior to the normal expiry date of such Legacy Options (the "Restricted Options"), the expiry date of all Restricted Options shall be extended for a period of seven business days following the end of the Black-Out Period (or such longer period as permitted by the Exchange and approved by the Committee).

Subject to the provisions of the Legacy Share Option Plan, if permitted by the Committee, an Optionee may elect to exercise a vested Legacy Option by surrendering such Legacy Option in exchange for the In-the-Money Value of Legacy Option in lieu of purchasing the number of Common Shares then issuable on the exercise of the vested Legacy Option. If the Optionee so elects to exercise the Legacy Option, the Optionee shall be entitled to payment of the In-the-Money Value of the vested Legacy Option determined as of the Pricing Date. The In-the-Money Value shall be paid in Common Shares issued from treasury with the number of Common Shares issuable being equal to the number obtained by dividing the In-the-Money Value of Legacy Options in respect of which such election is made by the Current Market Price on the Pricing Date.

A Optionee may make an offer (the "Surrender Offer") to the Company, at any time, for the disposition and surrender by the Optionee to the Company (and the termination thereof) of any of Legacy Options granted under the Legacy Share Option Plan for an amount (not to exceed the Fair Market Value of Common Shares less the exercise price of Legacy Options) specified in the Surrender Offer by the Optionee, and the Company may, but is not obligated to, accept the Surrender Offer, subject to any regulatory approval required. If the Surrender Offer, either as made or as renegotiated, is accepted, Legacy Options in respect of which the Surrender Offer relates shall be surrendered and deemed to be terminated and cancelled and shall cease to grant the Optionee any further rights thereunder upon payment of the amount of the agreed Surrender Offer by the Company to the Optionee. The Company may, in its sole discretion, elect to allow an Optionee to claim such deductions in computing taxable income of such Optionee, if any, that may be available to the Optionee in respect of any amount received by the Optionee, provided that the Company shall be under no obligation, express or implied, to make such election.

In the event: (a) of any change in Common Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise; or (b) that any rights are granted to all or substantially all shareholders to purchase Common Shares at prices substantially below Fair Market Value; or (c) that, as a result of any recapitalization, merger, consolidation or other transaction, Common Shares are converted into or exchangeable for any other securities or property; then the Company Board may make such adjustments to the Legacy Share Option Plan, to any Legacy Options and to any agreements for Legacy Options outstanding under the Legacy Share Option Plan, and make such amendments to any agreements for Legacy Options outstanding under the Legacy Share Option Plan, as the Company Board may, in its sole discretion, consider appropriate in the circumstances to prevent dilution or enlargement of the rights granted to Optionees thereunder and/or to provide for the Optionees to receive and accept such other securities or property in lieu of Common Shares, and the Optionees shall be bound by any such determination.

For greater certainty, and notwithstanding anything to the contrary to the foregoing paragraph, no adjustment shall be made in accordance with respect to the issue of Common Shares being made pursuant to or in connection with (i) any share option plan or share purchase plan, including the Legacy Share Option Plan, in force from time to time for existing or proposed officers, directors, employees or Service Providers of the Company, or (ii) the issuance of additional Common Shares pursuant to a public offering or private placement by the Company or a take-over bid or tender offer made by the Company for the securities of another entity.

Except in the case of a transaction that is a Change of Control and to which accelerated vesting and termination of Legacy Options applies, if the Company enters into any transaction or series of transactions whereby the Company or All or Substantially All of the Assets would become the property of another trust, body corporate, partnership or other person (a "Successor"), whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, prior to or contemporaneously with the consummation of such transaction, the Company and the Successor will execute such instruments and do such things as the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will assume the covenants and obligations of the Company under the Legacy Share Option Plan outstanding on consummation of such transaction. Any such Successor shall succeed to, and be substituted for, and may exercise every right and power of the Company under the Legacy Share Option Plan with the same effect as though the Successor had been named as the Company therein and thereafter, the Company shall be relieved of all obligations and covenants under the Legacy Share Option Plan and the obligation of the Company to the Optionees in respect of Legacy Options shall terminate and be at an end and the Optionees shall cease to have any further rights in respect thereof including, without limitation, any right to acquire Common Shares upon vesting of Legacy Options.

Notwithstanding any other provision in the Legacy Share Option Plan or the terms of any option agreement, if there takes place a Change of Control, all issued and outstanding Legacy Options shall terminate on the 90^th day after the occurrence of such Change of Control, or at such earlier time as may be established by the Company Board, in its absolute discretion, prior to the time such Change of Control takes place.

The Committee may, subject to any required approval of any Exchange, amend or discontinue the Legacy Share Option Plan and Legacy Options granted thereunder at any time without the approval of the shareholders of the Company or any Optionee whose Legacy Option is amended or terminated, provided that, subject to the terms of the Legacy Share Option Plan, no amendment to the Legacy Share Option Plan or Legacy Options granted pursuant to the Legacy Share Option Plan may be made without the consent of the Optionee, if it adversely alters or impairs any Legacy Option previously granted to such Optionee under the Legacy Share Option Plan. Without limitation of the foregoing, such amendments include, without limitation: (a) amendments of a "housekeeping nature" nature, including, without limitation, amending the wording of any provision of the Legacy Share Option Plan for the purpose of clarifying the meaning of existing provisions or to correct or supplement any provision of the Legacy Share Option Plan that is inconsistent with any other provision of the Legacy Share Option Plan, correcting grammatical or typographical errors and amending the definitions contained within the Legacy Share Option Plan respecting the administration of the Legacy Share Option Plan; (b) amending Legacy Options under the Legacy Share Option Plan, including with respect to the expiry date (provided that the term of the Legacy Option does not exceed 15 years from the date the Legacy Option is granted and that such Legacy Option is not held by an Insider) and effect of termination of a Optionee's employment or cessation of the Optionee's service; or (c) amendments necessary to comply with applicable law or the requirements of any Exchange. Notwithstanding the foregoing, the Legacy Share Option Plan or any outstanding Legacy Option granted thereunder may not be amended without shareholder approval to:

(a) permit Legacy Options to be issued other than pursuant to the Plan of Arrangement;

(b) increase the number of Common Shares reserved for issuance pursuant to Legacy Options in excess of the limit prescribed in the Legacy Share Option Plan;

(c) extend the expiry date of any Legacy Option granted to an Insider (other than as permitted by the terms and conditions of the Legacy Share Option Plan);

(d) permit an Optionee to transfer Legacy Options to a new beneficial holder other than for estate settlement purposes;

(e) reduce the limitations on Legacy Options contained in the Legacy Share Option Plan; and

Notwithstanding the foregoing, the Committee may amend or terminate the Legacy Share Option Plan or any outstanding Legacy Option granted under the Legacy Share Option Plan at any time without the approval of the shareholders of the Company or any Optionee whose Legacy Option is amended or terminated in order to conform the Legacy Share Option Plan or such Legacy Option, as the case may be, to applicable law or regulation or the requirements of any relevant stock exchange or regulatory authority, whether or not that amendment or termination would affect any accrued rights or adversely alter or impair any Legacy Option previously granted.

The Company has also adopted the Equity Incentive Award Plan and Share Option Plan. For summaries of the Equity Incentive Award Plan and Share Option Plan, see "Matters To Be Acted Upon At The Meeting - Matters Respecting New Equity Incentive Plans" in this Information Circular.

The Company has a formal "clawback" policy on executive incentive compensation, including, without limitation, bonuses, share options and share awards, that may be awarded to our executive officers when (i) the executive engages in willful misconduct or fraud which causes or significantly contributes to a restatement of our financial statements due to our material noncompliance with any applicable financial reporting requirement under securities laws, (ii) the executive receives incentive compensation calculated on the achievement of those financial results, and (iii) the incentive compensation received would have been lower had the financial statements been properly reported. The policy provides that when a clawback is triggered, upon the recommendation of the Governance and ESG Committee, the Company Board may, in its sole discretion and to the extent that it determines it is in the Company's best interests to do so, require the executive to repay the amount of incentive compensation relating to the year(s) subject to the restatement or received upon exercise or payment of incentive compensation in or following the year(s) subject to the restatement that is in excess of the incentive compensation the executive would have received if the incentive compensation had been computed in accordance with the results as restated, calculated on an after tax basis.

As at December 31, 2022, the Company did not have any equity incentive plans. See "Matters Related to New Equity Incentive Plans", "Executive Compensation – Legacy Share Award Plan" and "Executive Compensation – Legacy Share Option Plan".

Effective as of February 23, 2023 and as amended and restated effective May 1, 2023

The purpose of this Plan is to aid in attracting, retaining and motivating the officers, employees and other eligible Service Providers of the HEI Group in the growth and development of the HEI Group by providing them with the opportunity through Options to acquire an increased proprietary interest in the Corporation.

This Plan shall be administered by the Committee pursuant to any rules of procedure that may be fixed by the Board.

To the extent permitted by law, the Committee may delegate or sub-delegate to one or more of its members, to any director or officer of the Corporation or to one or more agents all or any of the powers conferred on the Committee under this Plan, and the Committee or any person to whom it has delegated or sub-delegated authority as aforesaid may employ one or more persons to render advice with respect to any responsibility the Committee or such person may have under this Plan.

For greater certainty and without limiting the discretion conferred on the Committee pursuant to this Article, the Committee's decision to approve the grant of an Option in any period shall not require the Committee to approve the grant of an Option to any Service Provider in any other period; nor shall the Committee's decision with respect to the size or terms and conditions of an Option grant in any period require it to approve the grant of an Option of the same or similar size or with the same or similar terms and conditions to any Service Provider in any other period. The Committee shall not be precluded from approving the grant of an Option to any Service Provider solely because such Service Provider may previously have been granted an Option under this Plan or any other similar compensation arrangement of the Corporation or a member of the HEI Group. There is no obligation for uniformity of treatment of Service Providers or Optionees under this Plan. The terms and conditions of Options need not be the same with respect to any Optionee or with respect to different Optionees. No Service Provider has any claim or right to be granted an Option.

The Committee may from time to time designate officers and employees of, and other eligible Service Providers to, the HEI Group to whom Options may be granted and the number of Shares to be optioned to each, provided that the number of Shares to be optioned shall not exceed the limitations provided in Article 4 hereof.

(a) subject to Articles 11 and 12, the number of Shares reserved for issuance on exercise of Options outstanding under this Plan, together with the number of Shares reserved for issuance under all other Security Based Compensation Arrangements of the Company that provide for the issuance of Shares, shall not at any time exceed 10% of the Shares then issued and outstanding;

(b) no one Service Provider may be granted any Option which, together with all Options then held by such Optionee, would entitle or enable such Optionee to receive a number of Shares which is greater than 5% of the outstanding Shares, calculated on an undiluted basis; and

under this Plan, or when combined with all of the Corporation's other Security Based Compensation Arrangements shall not exceed 10% of the Corporation's total issued and outstanding Shares, respectively.

Options that are cancelled, surrendered, terminated or expire prior to the exercise of all or a portion thereof shall result in the Shares that were reserved for issuance thereunder being available for a subsequent grant of Options pursuant to this Plan to the extent of any Shares issuable thereunder that are not issued under such cancelled, surrendered, terminated or expired Options. For greater certainty, any increase in the issued and outstanding Shares will result in an increase in the number of Shares available under this Plan

The Committee may, in its sole discretion, determine: (i) the time during which Options shall vest; (ii) the method of vesting; or (iii) that no vesting restriction shall exist. In the absence of any determination by the Committee to the contrary, Options will vest and be exercisable as to one-quarter (1/4) of the total number of Shares subject to the Options on each of the first, second, third and fourth anniversaries of the date of grant (computed in each case rounded down to the nearest whole Share with any fractional amount vesting on such fourth anniversary) subject to continued employment or service with the HEI Group. Notwithstanding the foregoing, the Committee may, at its sole discretion at any time or in the Option Agreement in respect of any Options granted, accelerate or provide for the acceleration of vesting of Options previously granted.

The exercise price of Options granted under this Plan shall be fixed by the Committee when such Options are granted, provided that the exercise price of Options shall not be less than such minimum price as may be required by the Exchange(s), if any, on which the Shares are listed at the time of grant.

The period during which an Option is exercisable shall, subject to the provisions of this Plan requiring or permitting the acceleration of rights of exercise or the extension of the exercise period, be such period, not in excess of ten (10) years, as may be determined from time to time by the Committee, but subject to the rules of any Exchange(s) or other regulatory body having jurisdiction, and in the absence of any determination to the contrary will be five (5) years from the date of grant. Each Option shall, among other things, contain provisions to the effect that the Option shall be personal to the Optionee and shall not be assignable. In addition, unless the Corporation and an Optionee agree otherwise in an Option Agreement or other written agreement (such as an agreement of employment or a Retirement Agreement), each Option shall provide that:

(a) Death - upon the death of the Optionee, the Option shall terminate on the earlier of (i) the date determined by the Committee which shall not be more than twelve (12) months from the Cessation Date and, in the absence of any determination to the contrary, twelve (12) months from the Cessation Date and (ii) the Expiry Date of such Option;

(b) Other Termination - if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group (other than by reason of death, termination for Cause, voluntary resignation or Retirement), the Option shall terminate on the earlier of (i) expiry of the period as prescribed by the Committee at the time of grant, following the Cessation Date, and, in the absence of any determination to the contrary, at the later of (A) ninety (90) days following the Cessation Date, and (B) the end of the notice period used for calculating severance to which the Optionee is entitled as a result of the Optionee's cessation as a Service Provider pursuant to a written contract of employment, if any, with an entity in the HEI Group; and (ii) the Expiry Date of such Option;

(c) Termination for Cause - if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group by reason of termination for Cause, the Option shall terminate immediately on the Cessation Date (whether notice of such termination occurs verbally or in writing);

(d) Voluntary Resignation - if the Optionee shall no longer be an officer of or be in the employ of, or consultant or other Service Provider to, any of the entities comprising the HEI Group by reason of voluntary resignation, effective as of the day that is fourteen (14) days after the Cessation Date the Option shall terminate;

(e) Retirement - if the Optionee shall no longer be an officer of or be in the employ of any of the entities comprising the HEI Group due to the Optionee's Retirement, the Option shall continue in accordance with its terms and the exercise period shall not be accelerated as a result of the Optionee's Retirement;

provided that the number of Shares that the Optionee (or his or her heirs or successors) shall be entitled to purchase until such date of termination: (i) shall in the case of death of the Optionee, be all of the Shares that may be acquired on exercise of the Options held by such Optionee (or his or her heirs or successors) whether or not previously vested, and the vesting of all such Options shall be accelerated on the Cessation Date; and (ii) in any case other than death or termination for Cause, shall be the number of Shares which the Optionee was entitled to purchase on the Cessation Date. In the event of termination for Cause, all of the Shares optioned, whether vested or unvested shall be forfeited.

If any Options may not be exercised due to any Black-Out Period at any time within the three business day period prior to the normal expiry date of such Options (the "Restricted Options"), the expiry date of all Restricted Options shall be extended for a period of seven business days following the end of the Black-Out Period (or such longer period as permitted by the Exchange(s) and approved by the Committee).

Subject to the provisions of this Plan, a vested Option may be exercised from time to time prior to the Expiry Date thereof by delivery to the Corporation at its head office in Calgary, Alberta or such other place as may be specified by the Corporation, of a written notice of exercise specifying the number of Shares with respect to which the Option is being exercised and accompanied by payment in full of the purchase price of the Shares then being purchased.

No Option holder who is resident in the United States may exercise Options unless the Shares issuable by the Corporation upon such exercise are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act.

Subject to the provisions of this Plan, if permitted by the Committee, an Optionee may elect to exercise a vested Option by surrendering such Option in exchange for the In-the-Money Value (as defined below) of the Option in lieu of purchasing the number of Shares then issuable on the exercise of the vested Option. If the Optionee so elects to exercise the Option, the Optionee shall be entitled to payment of the In-the-Money Value of the vested Option determined as of the date (the "Pricing Date") the Corporation receives notice of the exercise of such Option. The In-the-Money Value shall be paid in Shares issued from treasury with the number of Shares issuable being equal to the number obtained by dividing the In-the-Money Value of the Options in respect of which such election is made by the Current Market Price on the Pricing Date. "In-the-Money Value" means the amount by which the Current Market Price on the Pricing Date exceeds the exercise price of the applicable Options, multiplied by the number of Shares related to the applicable Options. "Current Market Price" means, as at any date when the Current Market Price is to be determined, the volume weighted average trading price per Share on the TSX, or, if the Shares are not listed on the TSX, on any Exchange in Canada or the United States, for the last five (5) trading days immediately prior to the date of determination, or if the Shares are not listed upon any stock exchange in Canada or the United States, the Current Market Price shall be determined by the Board of Directors acting in good faith. An Option may be exercised pursuant to this Article 9 from time to time by delivery to the Corporation at its head office in Calgary, Alberta or such other place as may be specified by the Corporation, of a written notice of exercise specifying that the Optionee has elected to make a cashless exercise of such Option and the number of Options to be exercised (provided that the Committee may, in its sole discretion, vary the aforementioned procedure for exercising an Option from time to time). The Corporation will not be required, upon the exercise of any Options pursuant to this Article 9, to issue fractions of Shares or to distribute certificates which evidence fractional Shares. In lieu of fractional Shares, the Corporation will pay to the Optionee within ten (10) business days after the exercise date, an amount in lawful money of Canada equal to the then Current Market Price of such fractional interest, provided that the Corporation will not be required to make any payment, calculated as aforesaid, that is less than $10.00. Any reference in this Article 9 to the issuance of Shares or the payment of cash is subject to compliance with Article 17.

An Optionee may make an offer (the "Surrender Offer") to the Corporation, at any time, for the disposition and surrender by the Optionee to the Corporation (and the termination thereof) of any of the Options granted hereunder for an amount (not to exceed the Fair Market Value of the Shares less the exercise price of the Options) specified in the Surrender Offer by the Optionee, and the Corporation may, but is not obligated to, accept the Surrender Offer, subject to any regulatory approval required. If the Surrender Offer, either as made or as renegotiated, is accepted, the Options in respect of which the Surrender Offer relates shall be surrendered and deemed to be terminated and cancelled and shall cease to grant the Optionee any further rights thereunder upon payment of the amount of the agreed Surrender Offer by the Corporation to the Optionee. Any reference in this Article 10 to the payment of cash is subject to compliance with Article 17.

(a) of any change in the Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise; or

(b) that any rights are granted to all or substantially all shareholders to purchase Shares at prices substantially below Fair Market Value; or

(c) that, as a result of any recapitalization, merger, consolidation or other transaction, the Shares are converted into or exchangeable for any other shares;

then the Board may, subject to any required approval of the TSX, make such adjustments to this Plan, to any Options and to any Option Agreements outstanding under this Plan, and make such amendments to any Option Agreements outstanding under this Plan, as the Board may, in its sole discretion, consider appropriate in the circumstances to prevent inappropriate dilution or enlargement of the rights granted to Optionees hereunder and/or to provide for the Optionees to receive and accept such other shares in lieu of Shares, and the Optionees shall be bound by any such determination.

For greater certainty, and notwithstanding anything to the contrary in this Article 11, no adjustment shall be made in accordance with this Article 11 with respect to the issue of Shares being made pursuant to or in connection with (i) any share option plan or share purchase plan, including this Plan, in force from time to time for existing or proposed officers, directors, employees or Service Providers of the Corporation, or (ii) the issuance of additional Shares pursuant to a public offering or private placement by the Corporation or a take-over bid or tender offer made by the Corporation for the securities of another entity.

With respect to any Options which are governed by section 7 of the Tax Act, all adjustments and actions described in this Article 11 shall be structured in compliance with the requirements of subsections 7(1.4) (if done by way of an exchange of Options) or with subsections 110(1.7) and 110(1.8) of the Tax Act.

Except in the case of a transaction that is a Change of Control and to which Article 13 applies, if the Corporation enters into any transaction or series of transactions whereby the Corporation or All or Substantially All of the Assets would become the property of any other trust, body corporate, partnership or other person (a "Successor"), whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, prior to or contemporaneously with the consummation of such transaction the Corporation and the Successor will execute such instruments and do such things as the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will assume the covenants and obligations of the Corporation under this Plan and the Option Agreements outstanding on consummation of such transaction. Any such Successor shall succeed to, and be substituted for, and may exercise every right and power of the Corporation under this Plan and Option Agreements with the same effect as though the Successor had been named as the Corporation herein and therein and thereafter, the Corporation shall be relieved of all obligations and covenants under this Plan and such Option Agreements and the obligation of the Corporation to the Optionees in respect of the Options shall terminate and be at an end and the Optionees shall cease to have any further rights in respect thereof including, without limitation, any right to acquire Shares upon vesting of the Options. With respect to any Options that are governed by section 7 of the Tax Act, to the extent commercially practicable, any such assumption by the Successor will be structured so as to be governed by subsection 7(1.4) of the Tax Act.

Notwithstanding any other provision in this Plan or the terms of any Option Agreement, upon the consummation of a Change of Control, all issued and outstanding Options shall be automatically fully vested and exercisable (whether or not then vested) immediately prior to the time such Change of Control takes place and shall terminate on the 90^th day after the occurrence of such Change of Control, or at such earlier time as may be established by the Board, in its absolute discretion, prior to the time such Change of Control takes place.

An Optionee shall not have any of the rights or privileges of a shareholder of the Corporation in respect of any Shares issuable upon exercise of an Option until certificates representing such Shares have been issued and delivered.

This Plan shall be subject to the approval, if required, of any Exchange(s) on which the Shares are listed for trading. Any Options granted prior to receipt of such approval and after listing on any such Exchange(s) shall be conditional upon such approval being given and no such Options may be exercised unless such approval, if required, is given.

A written agreement (an "Option Agreement") will be entered into between the Corporation and each Optionee to whom an Option is granted hereunder, which Option Agreement will set out the number of Shares subject to Option, the exercise price, the vesting dates, circumstances when vesting of Options may be accelerated, the Expiry Date, whether any of the Options are Options in respect of "non-qualified securities" under the Tax Act, and any other terms approved by the Committee, all in accordance with the provisions of this Plan. The Option Agreement will be in such form as the Committee may from time to time approve or authorize the officers of the Corporation to enter into and may contain such terms as may be considered necessary in order that the Option will comply with any provisions respecting Options in the income tax or other laws in force in any country or jurisdiction of which the person to whom the Option is granted may from time to time be a resident or citizen or the rules of any regulatory body having jurisdiction over the Corporation. Such Option Agreements may also contain such other provisions as the Committee may determine.

If an Optionee fails to acknowledge a grant of an Option by acceptance of the Option Agreement within the time specified by the Committee, the Corporation reserves the right to revoke the Option grant. Participation in this Plan by any Optionee shall be construed as irrevocable acceptance by the Participant of the terms and conditions set out herein and all rules and procedures adopted hereunder and as amended from time to time.

The Corporation shall have the power and the right to deduct or withhold, or require (as a condition of exercise) an Optionee to remit to the Corporation, the required amount to satisfy, in whole or in part, federal, provincial, state and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan, including the grant, exercise or surrender of Options granted under this Plan. With respect to required withholding, the Corporation shall have the irrevocable right to (and the Optionee consents to) the Corporation setting off any amounts required to be withheld, in whole or in part, against amounts otherwise owing by the Corporation to such Optionee (whether arising pursuant to the Optionee's relationship as an officer or employee of the Corporation or as a result of the Optionee providing services on an ongoing basis to the Corporation or otherwise), or may make such other arrangements as are satisfactory to the Optionee and the Corporation. In addition, the Corporation may elect, in its sole discretion, to satisfy the withholding requirement, in whole or in part, by withholding such number of Shares as it determines are required to be sold by the Corporation, as trustee, to satisfy the withholding obligation net of selling costs (which costs shall be the responsibility of the Optionee and which shall be and are authorized to be deducted from the proceeds of sale). The Optionee consents to such sale and grants to the Corporation an irrevocable power of attorney to effect the sale of such Shares and acknowledges and agrees that the Corporation does not accept responsibility for the price obtained on the sale of such Shares. Any reference in this Plan to the issuance of Shares or a payment of cash is expressly subject to this Article 17.

All Options granted to persons who are granted Options by virtue of their employment with the Corporation or a Subsidiary shall have such terms and conditions so as to be governed by section 7 of the Tax Act.

Optionees (or their beneficiaries) shall be responsible for all taxes with respect to any Option outstanding under this Plan, whether arising as a result of the grant or exercise of Options or otherwise. The Corporation and the Committee make no guarantees to any person regarding the tax treatment of an Option or payments made under this Plan and none of the Corporation or any of its directors, officers, employees or representatives shall have any liability to an Optionee with respect thereto. Optionees are advised to consult with their own tax advisors.

The Corporation shall make reasonable commercial efforts to ensure that Optionees receive the most favourable tax treatment permitted by law in connection with the exercise and/or surrender of Options, including, without limitation, executing any tax elections necessary for an Optionee to receive capital-gains like tax treatment under paragraph 110(1)(d) of the Tax Act (or any successor provision thereof), provided that Corporation shall not be liable if the paragraph 110(1)(d) deduction is not available in respect of any Options granted under this Plan due to a failure of the Options to meet the conditions required to qualify for such deduction (other than the requirement for any election under subsection 110(1.1) of the Tax Act if the Options are subject to a cashless exercise under Article 9 or are surrendered under Article 10).

Notwithstanding any other provision of this Plan, grants of Options to Participants who are subject to United States federal income taxation ("U.S. Taxpayers") under the United States Internal Revenue Code of 1986, as amended (the "Code"), shall be made and administered under the terms of Schedule A to this Plan.

Participation in this Plan by an Optionee is entirely voluntary and does not affect the Optionee's employment or continued retainer by, or other engagement with, any of the entities comprising the HEI Group, nor does it interfere in any way with the right of the Optionee or any of the entities comprising the HEI Group to terminate the Optionee's employment or service provision at any time. Neither this Plan nor the granting to an Optionee of an Option hereunder of itself gives such Optionee any right to continue to be an officer, employee or Service Provider of any of the entities comprising the HEI Group. None of the terms and conditions governing an Option shall be affected by any change in the terms of the Optionee's employment or by engagement with any of the entities comprising the HEI Group so long as the Optionee continues to hold Options. The terms of this Plan or any option agreement shall not affect in any manner whatsoever the terms or validity of any employment or other services agreement to which the Corporation is a party. Schedule A is incorporated herein by reference

All decisions and interpretations by the Committee respecting this Plan or Options granted hereunder, including decisions as to adjustments in the number of Shares to be received upon exercise of an Option or the exercise price thereof in accordance with Article 11 shall be final and binding on the Corporation and all Optionees and their respective successors, heirs and legal representatives, as applicable.

Unless otherwise indicated, all monetary amounts in this Plan and any Option Agreement are in Canadian dollars. Unless otherwise permitted by the Committee, all amounts payable under or in connection with this Plan or any Option Agreement shall be paid in Canadian dollars. If any monetary amount needs to be converted from U.S. dollars to Canadian dollars or vice versa for the purposes of this Plan or any Option Agreement, then the exchange rate for such conversion shall be determined by the Committee.

(a) Notwithstanding any other provision of the Plan, grants of Options to Participants who are U.S. Taxpayers under the Code or any successor thereto, shall be made and administered under the terms of this Schedule A to the Plan. With respect to any Participant who is a U.S. Taxpayer, in no event shall the exercise price of the Options be less than Fair Market Value on the date of grant as determined under Section 409A of the Code.

(b) The Board or Committee, as the case may be, shall interpret and construe the Plan and take all authorized actions with respect to any U.S. Taxpayer in a manner that is consistent with applicable U.S. Treasury regulations and other guidance issued pursuant to Section 409A of the Code. However, neither the Board, the Committee, the Corporation nor any other person connected with the Plan in any capacity makes any representation, commitment, or guarantee that any tax treatment shall be applicable with respect to any grant of Options, any amounts deferred under this Plan, or any amounts paid to any person hereunder.

(a) Shares issued pursuant to the Plan shall not be issued under the Plan to a Participant unless the issuance of those securities shall comply with all relevant laws, including, the U.S. Securities Act, applicable state securities laws, and the requirements of any stock exchange or automated inter-dealer quotation system in the United States upon which the Shares may then be listed or quoted, if applicable. The issuance shall also be subject to the approval of counsel for the Corporation with respect to such compliance, including the availability of an exemption from registration for the issuance of any Shares issued pursuant to the Plan. The unavailability of an exemption from registration for the issuance to a Participant of any Shares issued pursuant to the Plan or the inability of the Corporation to obtain from any regulatory body the authority deemed by the Corporation to be necessary for the lawful issuance and sale of any Shares under the Plan, shall relieve the Corporation of any liability for not issuing Shares to the Participant.

(b) As a condition to the issuance of the Shares pursuant to the Plan, the Corporation may require the Participant to execute such documentation and make such representations and warranties as may be necessary to comply with federal and state securities laws or as may be required by this Plan.

The Plan and all Options granted hereunder are subject to any written clawback policies that the Corporation, with the approval of the Board or an authorized committee thereof, may adopt either prior to or following the effective time, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the SEC and that the Corporation determines should apply to Options. Any such policy may subject a Participant's Options and amounts paid or realized with respect to Options to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Corporation's material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy.

In the event that the Board appoints itself or another committee of the Board to administer this Plan, all references in this Plan to the Committee will be deemed to be references to the Board or such other committee of the Board, as applicable.

The Committee shall have the authority in its sole discretion to administer this Plan and to exercise all the powers and authorities either specifically granted to it under this Plan or necessary or advisable in the administration of this Plan, subject to and not inconsistent with the express provisions of this Plan and of Section 10 hereof, including, without limitation:

(d) to determine the Service Providers to whom, and the time or times at which Awards shall be granted and shall become issuable or payable, as the case may be;

(e) to determine the number of Shares to be covered by each Share Award, the number of Incentive Awards to be granted and in each case the allocation between Restricted Awards and Performance Awards;

For greater certainty and without limiting the discretion conferred on the Committee pursuant to this Section, the Committee's decision to approve the grant of an Award in any period shall not require the Committee to approve the grant of an Award to any Service Provider in any other period; nor shall the Committee's decision with respect to the size or terms and conditions of an Award in any period require it to approve the grant of an Award of the same or similar size or with the same or similar terms and conditions to any Service Provider in any other period. The Committee shall not be precluded from approving the grant of an Award to any Service Provider solely because such Service Provider may previously have been granted an Award under this Plan or any other similar compensation arrangement of the Corporation or a member of the HEI Group. There is no obligation for uniformity of treatment of Service Providers or Participants under this Plan. The terms and conditions of Awards need not be the same with respect to any Participant or with respect to different Participants. No Service Provider has any claim or right to be granted an Award.

Awards may be granted only to persons who are employees or officers of the Corporation or a member of the HEI Group or who are consultants or other service providers to the Corporation or a member of the HEI Group (collectively, "Service Providers"); provided, however, that the participation of a Service Provider in this Plan is voluntary and any decision not to participate shall not affect any Service Provider's employment with or service to the Corporation or any member of the HEI Group. For greater certainty, a transfer of employment or services between the Corporation and a member of the HEI Group or between a members of the HEI Group shall not be considered an interruption or termination of the employment of a Participant for any purpose of this Plan.

The Committee, in its sole discretion, shall determine which Service Providers will participate in this Plan. In determining the Service Providers to whom Awards may be granted ("Participants") and the number of Shares to be covered by each Share Award or the number of Incentive Awards granted, the Committee may take into account such factors as it shall determine in its sole discretion, including without limitation, if so determined by the Committee, any one or more of the following factors:

(a) compensation data for comparable benchmark positions among the Peer Comparison Group or among other comparison groups;

(c) the Corporate Performance Measures for the applicable period compared with internally established performance measures approved by the Committee and/or similar performance measures of members of the Peer Comparison Group or among other comparison groups for such period;

(d) the individual contributions and potential contributions of the Participant to the success of the Corporation;

(e) any bonus payments paid or to be paid to the Participant in respect of his or her individual contributions and potential contributions to the success of the Corporation;

(f) the Fair Market Value or current market price of the Shares at the time of such Award; and

(g) such other factors as the Committee shall deem relevant in its sole discretion in connection with accomplishing the purposes of this Plan.

Subject to Sections 6(l) and 9 hereof, the aggregate number of Shares reserved for issuance pursuant to Awards granted and outstanding hereunder, together with the aggregate number of Shares reserved for issuance under all other security based compensation arrangements (as defined in Section 6(c)) of the Company that provide for the issuance of Shares, shall not at any time exceed ten percent (10%) of the Shares then issued and outstanding.

If any Award granted under this Plan shall expire, terminate or be cancelled for any reason without the Shares issuable thereunder having been issued in full, any unissued Shares to which such Award relates shall be available for the purposes of the granting of further Awards under this Plan. For greater certainty, any increase in the issued and outstanding Shares will result in an increase in the number of Shares available under this Plan.

For purposes of the calculations in this Section only, it shall be assumed that all issued and outstanding Incentive Awards will be settled by the issuance of Shares from treasury, notwithstanding the Corporation's right pursuant to Section 6(h) hereof to settle the Incentive Award Value underlying Incentive Awards in cash or by purchasing Shares on the open market.

Each Award granted under this Plan shall be subject to the terms and conditions of this Plan and evidenced by a written agreement between the Corporation and the Participant (an "Incentive Award Agreement" in the case of an Incentive Award and a "Share Award Agreement" in the case of a Share Award) which agreement shall comply with, and be subject to, the requirements of the Exchange and the following terms and conditions (and with such other terms and conditions as the Committee, in its sole discretion, shall establish):

(a) Type of Awards - The Committee shall determine the number of Shares to be awarded to a Participant pursuant to the Share Award and/or the number of Incentive Awards to be awarded to a Participant in accordance with the provisions set forth in Section 4 hereof and shall designate such Award as either a "Restricted Award" or a "Performance Award", as applicable, in the Award Agreement relating thereto.

(b) Tax Treatment - Notwithstanding any other provision of this Plan, (i) all Share Awards granted to employees and officers of a member of the HEI Group shall have such terms and conditions required or desirable to ensure that such Share Awards are continuously governed by section 7 of the Income Tax Act (Canada) and, except as provided in the second paragraph of Section 6(g) hereof, all Share Awards shall be settled solely by the issuance of Shares from treasury; and (ii) all Incentive Awards granted to employees and officers of a member of the HEI Group shall be granted as a bonus for services rendered by the Participant in the year of grant and shall have such terms and conditions required or desirable to ensure that such Incentive Awards do not constitute a "salary deferral arrangement" within the meaning of the Income Tax Act (Canada) by virtue of the exception in paragraph (k) of the definition thereof.

(c) Limitations on Awards - No one Service Provider may be granted any Award which, together with all Awards then held by such Participant, would entitle or enable such Participant (assuming in the case of Incentive Awards that all such Incentive Awards would be settled by the issuance of Shares from treasury) to receive a number of Shares which is greater than 5% of the outstanding Shares, calculated on an undiluted basis. In addition: (i) the number of Shares issuable to Insiders at any time, under all security based compensation arrangements of the Corporation, shall not exceed 10% of the issued and outstanding Shares; and (ii) the number of Shares issued to Insiders, within any one year period, under all security based compensation arrangements of the Corporation, shall not exceed 10% of the issued and outstanding Shares. For this purpose, "security based compensation arrangements" has the meanings ascribed thereto in Part VI of the TSX Company Manual. For purposes of the calculations in this Section, it shall be assumed that all issued and outstanding Incentive Awards will be settled by the issuance of Shares from treasury, notwithstanding the Corporation's right pursuant to Section 6(h) to settle the Incentive Award Value underlying Incentive Awards in cash or by purchasing Shares on the open market.

The Committee shall not grant any Awards that may be denominated or settled in Shares to residents of the United States unless such Awards and the Shares issuable upon exercise or settlement thereof are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act.

(i) Restricted Awards: Subject to Section 6(i) hereof, with respect to any Restricted Award, unless otherwise determined by the Committee (and, for greater certainty, the Committee may in its sole discretion impose no or additional or different conditions to the determination of the Vesting Date(s) in respect of any Restricted Award including, without limitation, performance conditions, except that in no event may the Committee fix a Vesting Date for a Restricted Award that is an Incentive Award such that it is later than the Expiry Date), provided that the Participant remains in continuous employment or service with the Corporation or a member of the HEI Group through the applicable Vesting Date, the Vesting Date shall be the third anniversary of the grant date of the Restricted Award; provided, however, that, unless otherwise determined by the Committee:

(I) where a Participant is on a Leave of Absence, the Vesting Date or Vesting Dates for any Restricted Awards held by such Participant shall be suspended until such time as such Participant returns to active employment or active service, provided that where the period of the Leave of Absence exceeds three (3) months, the Vesting Date for any Restricted Award that occurs during or subsequent to the period of the Leave of Absence shall be extended by, and no adjustments shall be made to the Adjustment Ratio for Dividends that are paid during, that portion of the Leave of Absence that exceeds three (3) months, and further provided that, if any such extension would cause the Vesting Date or Vesting Dates to extend beyond the Expiry Date, such Awards and the rights to receive Shares in the case of Share Awards and the rights to receive payments in the case of Incentive Awards on such Vesting Date or Vesting Dates shall be terminated and all rights to receive Shares or payments thereunder shall be forfeited by the Participant;

(II) where a Vesting Date occurs for an Incentive Award on a date when a Participant is subject to a Black-Out Period, such Vesting Date shall be extended to the date which is seven business days following the end of such Black-Out Period, provided that if any such extension would cause the Vesting Date or Vesting Dates of such Incentive Award to extend beyond the Expiry Date, the amounts to be paid on such Vesting Date or Vesting Dates shall be paid on the Expiry Date notwithstanding the Black-Out Period. If the Expiry Date occurs and as a result of the previous sentence of this paragraph the Vesting Date will occur while a Black-Out Period is still in effect, then the Corporation shall pay the Participant the entire Incentive Award Value in cash (and not Shares) and, for greater certainty, the Corporation shall not have any right to pay the Incentive Award Value in whole or in part in Shares notwithstanding any other provision of this Plan or any Incentive Award Agreement;

(III) in the event of any Change of Control prior to the Vesting Dates determined in accordance with the above provisions of this Section 6(d)(i), and regardless of whether or not a Participant is on a Leave of Absence, the Vesting Date for all Shares awarded pursuant to such Restricted Award that is a Share Award that have not yet been issued and for the balance of the Incentive Award Value underlying such Restricted Award that is an Incentive Award that remains to be paid as of such time shall be the date which is immediately prior to the date upon which a Change of Control is completed; and

(IV) (A) on the Exercise Date thereof, the number of Shares to be issued pursuant to any Restricted Award that is a Share Award shall be adjusted by multiplying such number by the Adjustment Ratio applicable to such Restricted Award at such time, and (B) on the Vesting Date thereof, the Incentive Award Value payable pursuant to any Restricted Award that is an Incentive Award shall be adjusted by multiplying the number of Incentive Awards for which payment remains to be made by the Adjustment Ratio applicable to such Incentive Award at such time.

(ii) Performance Awards: Subject to Section 6(i) hereof, with respect to any Performance Award, unless otherwise determined by the Committee (and, for greater certainty, the Committee may in its sole discretion impose no or additional or different conditions to the determination of the Vesting Dates in respect of any Performance Award, except that in no event may the Committee fix a Vesting Date for a Performance Award that is an Incentive Award such that it is later than the Expiry Date), provided that the Participant remains in continuous employment or service with the Corporation or a member of the HEI Group through the applicable Vesting Date, the Vesting Date shall be the third anniversary of the grant date of the Performance Award; provided, however, that, unless otherwise determined by the Committee:

(I) where a Participant is on a Leave of Absence, the Vesting Date or Vesting Dates for any Performance Awards held by such Participant shall be suspended until such time as such Participant returns to active employment or active service, provided that where the period of the Leave of Absence exceeds three (3) months, the Vesting Date for any Performance Award that occurs during or subsequent to the period of the Leave of Absence shall be extended by, and no adjustments shall be made to the Adjustment Ratio for Dividends that are paid during, that portion of the Leave of Absence that exceeds three (3) months, and further provided that, if any such extension would cause the Vesting Date or Vesting Dates to extend beyond the Expiry Date, such Awards and the rights to receive Shares in the case of Share Awards and the rights to receive payments in the case of Incentive Awards on such Vesting Date or Vesting Dates shall be terminated and all rights to receive Shares or payments thereunder shall be forfeited by the Participant;

(III) in the event of any Change of Control prior to the Vesting Date determined in accordance with the above provisions of this Section 6(d)(ii), and regardless of whether or not a Participant is on a Leave of Absence, the Vesting Date for all Shares awarded pursuant to such Performance Award that is a Share Award that have not yet been issued and for the balance of the Incentive Award Value underlying such Performance Award that is an Incentive Award that remains to be paid as of such time shall be the date which is immediately prior to the date upon which a Change of Control is completed; and

(IV) (A) on the Exercise Date thereof, the number of Shares to be issued pursuant to any Performance Award that is a Share Award shall be adjusted by multiplying such number by (1) the Adjustment Ratio applicable to such Performance Award at such time, and (2) the Payout Multiplier applicable to such Performance Award at such time, and (B) on the Vesting Date thereof, the Incentive Award Value payable pursuant to any Performance Award that is an Incentive Award shall be adjusted by multiplying the number of Incentive Awards for which payment remains to be made by (1) the Adjustment Ratio applicable to such Performance Award at such time, and (2) the Payout Multiplier applicable to such Performance Award at such time.

Notwithstanding any other provision of this Plan, but subject to the limits described in Sections 5 and 6(c) hereof and any other applicable requirements of the Exchange or other regulatory authority, the Committee hereby reserves the right to make any additional adjustments to the number of Shares to be issued pursuant to or the Incentive Award Value underlying any Performance Award if, in the sole discretion of the Committee, such adjustments are appropriate in the circumstances having regard to the principal purposes of this Plan.

(e) Determination of the Payout Multiplier - Prior to the Vesting Date in respect of any Performance Award, the Committee will assess the performance of the Corporation for the applicable period. The weighting of the individual measures comprising the Corporate Performance Measures shall be determined by the Committee in its sole discretion and, following such determination, the Committee shall determine the applicable Payout Multiplier, which shall be not less than 0% and not more than 200%.

(f) Exercise of Share Awards - A Participant may elect to exercise Share Awards at any time and from time to time from and including the day the Vesting Date in respect of such Share Awards occurs until the Expiry Date of such Share Awards, by delivering to the Corporation a duly completed and executed Exercise Notice; provided, that no Participant who is resident in the United States may exercise Share Awards unless the Shares issuable by the Corporation upon such exercise are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act. If any Share Award may not be exercised due to any Black-Out Period at any time within the three business day period prior to the Expiry Date of such Share Award, the Expiry Date of all such Share Awards shall be extended for a period of seven business days following the end of the Black-Out Period (or such longer period as permitted by the Exchange and approved by the Committee).

(g) Payment in Respect of Share Awards - Subject to the paragraph immediately below, Share Awards shall be settled by the Corporation with Shares issued from the treasury of the Corporation.

A Participant may elect in an Exercise Notice to surrender a vested Share Award to the Corporation for cash in an amount equal to the aggregate Fair Market Value of such Shares that would otherwise be delivered in consideration for the surrender by the Participant to the Corporation of the right to receive such Shares under such Share Award (the "Cash Amount"). The Committee shall have the sole discretion to determine whether or not to accept the Participant's election. If the Committee accepts such election, then the Corporation shall pay the Cash Amount to the Participant in accordance with the provisions of this Section 6(g). If the Committee does not accept such election, such Share Award shall be settled by the Corporation with Shares issued from the treasury of the Corporation.

Any Shares deliverable or amount payable to a Participant in respect of a Share Award shall be delivered or paid to the Participant as soon as practicable following the Exercise Date and in any event within thirty (30) days of the Exercise Date (provided that any Shares deliverable or amount payable with respect to a Vesting Date that occurs after the Cessation Date, but before the Share Award has terminated in accordance with an applicable provision of Section 6(i), must occur not later than March 15 of the year following the year in which the Cessation Date occurs, if earlier) and the Corporation shall withhold from any such amount payable all amounts as may be required by law and in the manner contemplated by Section 7 hereof.

Where the determination of the number of Shares to be delivered to a Participant pursuant to a Share Award in respect of a particular exercise would result in the issuance of a fractional Share, the number of Shares deliverable shall be rounded down to the next whole number of Shares. No certificates representing fractional Shares shall be delivered pursuant to this Plan nor shall any cash amount be paid at any time in lieu of any such fractional interest.

No Share Award holder who is resident in the United States may settle a Share Award for Shares unless the Shares issuable upon settlement of the Share Awards are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act.

(h) Payment in Respect of Incentive Awards - The Corporation, at its sole and absolute discretion, shall have the option of settling the Incentive Award Value payable in respect of an Incentive Award by any of the following methods or by a combination of such methods:

The Incentive Award Value of any Incentive Award shall be determined as at the applicable Vesting Date and shall be settled on a date during the period from and including the day the Vesting Date in respect of such Incentive Awards occurs until the Expiry Date of such Incentive Award determined by the Committee.

The Corporation shall not determine whether the payment method shall take the form of cash or Shares until the Vesting Date, or some reasonable time prior thereto. A holder of an Incentive Award shall not have any right to demand, be paid in, or receive Shares in respect of the Incentive Award Value underlying an Incentive Award, at any time. Notwithstanding any election by the Corporation to settle any Incentive Award Value, or portion thereof, in Shares, the Corporation reserves the right to change its election in respect thereof at any time up until payment is actually made, and the holder of such Incentive Award shall not have the right, at any time to enforce settlement in the form of Shares of the Corporation.

Any amount payable to a Participant in respect of an Incentive Award shall be paid to the Participant as soon as practicable following the Vesting Date and in any event not later than December 31 of the third year following the year in which the Incentive Award was granted (provided that any amount payable with respect to a Vesting Date that occurs after the Cessation Date, but before the Incentive Award has terminated in accordance with an applicable provision of Section 6(i), must occur not later than either the Expiry Date or March 15 of the year following the year in which the Cessation Date occurs, if earlier than the Expiry Date) and the Corporation shall withhold from any such amount payable all amounts as may be required by law and in the manner contemplated by Section 7 hereof. In any event, the amount payable to a Participant in respect of an Incentive Award shall not be paid later than the Expiry Date of that Incentive Award.

Where the Corporation elects to pay any amounts pursuant to an Incentive Award by issuing Shares, and the determination of the number of Shares to be delivered to a Participant in respect of a particular Vesting Date would result in the issuance of a fractional Share, the number of Shares deliverable shall be rounded down to the next whole number of Shares. No certificates representing fractional Shares shall be delivered pursuant to this Plan nor shall any cash amount be paid at any time in lieu of any such fractional interest.

No Incentive Award holder who is resident in the United States may settle an Incentive Award for Shares unless the Shares issuable upon settlement of the Incentive Awards are registered under the U.S. Securities Act or are issued in compliance with an available exemption from the registration requirements of the U.S. Securities Act.

(i) Termination of Relationship as Service Provider - Unless otherwise determined by the Committee or unless otherwise provided in an Award Agreement pertaining to a particular Award or any written employment or consulting agreement governing a Participant's role as a Service Provider, the following provisions shall apply in the event that a Participant ceases to be a Service Provider:

(i) Death - If a Participant ceases to be a Service Provider as a result of the Participant's death, the Vesting Date for all Incentive Awards awarded to such Participant under any outstanding Incentive Award Agreements and for all Shares awarded to such Participant under any outstanding Share Award Agreements shall be accelerated to the Cessation Date, provided that the Committee, taking into consideration the performance of such Participant and the performance of the Corporation since the date of grant of the Award(s), may determine in its sole discretion the Payout Multiplier to be applied to any Performance Awards held by the Participant. The Expiry Date of any vested or unvested Share Awards held by the Participant at the date of death, which have not yet been subject to an Exercise Notice and subsequent settlement of the Share Award, shall be amended to the earlier of (i) one (1) year after the Cessation Date, and (ii) the Expiry Date of such Share Award.

(ii) Termination for Cause - If a Participant ceases to be a Service Provider as a result of termination for Cause, effective as of the Cessation Date all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, and whether (A) vested and unexercised or unsettled or (B) unvested, shall be immediately terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

(iii) Voluntary Resignation - If a Participant ceases to be a Service Provider as a result of a voluntary resignation, effective as of the day that is fourteen (14) days after the Cessation Date, all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, and whether (A) vested and unexercised or unsettled or (B) unvested, shall be terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

(iv) Retirement - If a Participant ceases to be a Service Provider as a result of the Participant's Retirement, all outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, shall continue in accordance with their terms and the Expiry Date shall not be accelerated as a result of such Retirement.

(v) Other Termination - If a Participant ceases to be a Service Provider for any reason other than as provided for in (i), (ii), (iii) and (iv) above, effective as of the date that is the later of (A) ninety (90) days after the Cessation Date, and (B) the end of the notice period used for calculating severance to which the Participant is entitled as a result of the Participant's cessation as a Service Provider pursuant to a written contract of employment, if any, with an entity in the HEI Group, and notwithstanding any other severance entitlements or entitlement to notice or compensation in lieu thereof, all then outstanding Award Agreements under which Awards have been made to such Participant, whether Restricted Awards or Performance Awards, shall be terminated and all rights to receive payments or Shares thereunder, as the case may be, shall be forfeited by the Participant.

(j) Rights as a Shareholder - Until the Shares granted pursuant to any Share Award have been issued or in the case of Incentive Awards until Shares have actually been issued should the Corporation elect to so issue Shares, in either case in accordance with the terms of this Plan, the Participant to whom such Award has been made shall not possess any incidents of ownership of such Shares including, for greater certainty and without limitation, the right to receive Dividends on such Shares and the right to exercise voting rights in respect of such Shares.

Such Participant shall only be considered a Shareholder in respect of such Shares when such issuance has been entered upon the records of the duly authorized transfer agent of the Corporation.

(k) Treatment of Non-Cash Dividends - In the case of a non-cash Dividend, including Shares or other securities or other property, the Committee will, in its sole discretion and subject to any required approval of the Exchange, determine whether or not such non-cash Dividend will be provided to the Award holder and, if so provided, the form in which it shall be provided.

(i) of any change in the Shares through subdivision, consolidation, reclassification, amalgamation, merger or otherwise;

(ii) that any rights are granted to all Shareholders to purchase Shares at prices substantially below Fair Market Value; or

(iii) that, as a result of any recapitalization, merger, consolidation or other transaction, the Shares are converted into or exchangeable for any other securities,

then, in any such case, the Board may, subject to any required approval of the Exchange, make such adjustments to this Plan, to any Awards and to any Award Agreements outstanding under this Plan as the Board may, in its sole discretion, consider appropriate in the circumstances to prevent inappropriate dilution or enlargement of the rights granted to Participants hereunder.

(m) Participant's Agreement to be Bound - If a Participant fails to acknowledge an Award by acceptance of the Award Agreement within the time specified by the Committee, the Corporation reserves the right to revoke the Award. Participation in this Plan by any Participant shall be construed as irrevocable acceptance by the Participant of the terms and conditions set out herein and all rules and procedures adopted hereunder and as amended from time to time.

When a Participant or other person becomes entitled to receive Shares, a cash payment or other amount in respect of any Award, the Corporation shall have the right to require the Participant or such other person to remit to the Corporation an amount sufficient to satisfy any withholding tax requirements relating thereto. Unless otherwise prohibited by the Committee or by applicable law, satisfaction of the withholding tax obligation may be accomplished by any of the following methods or by a combination of such methods:

(a) the tendering by the Participant of cash payment to the Corporation in an amount less than or equal to the total withholding tax obligation;

(b) the withholding by the Corporation or a member of the HEI Group, as the case may be, from the Shares otherwise due or payable to the Participant such number of Shares as it determines are required to be sold by the Corporation, as trustee, to satisfy the total withholding tax obligation (net of selling costs, which shall be paid by the Participant). The Participant consents to such sale and grants to the Corporation an irrevocable power of attorney to effect the sale of such Shares and acknowledges and agrees that the Corporation does not accept responsibility for the price obtained on the sale of such Shares; or

(c) the withholding by the Corporation or a member of the HEI Group, as the case may be, from any cash payment otherwise due to the Participant such amount of cash as is less than or equal to the amount of the total withholding tax obligation;

provided, however, that the sum of any cash so paid or withheld and the Fair Market Value of any Shares so withheld is sufficient to satisfy the total withholding tax obligation. Any reference in this Plan to the Incentive Award Value or payment of cash or issuance of Shares in settlement thereof or issuance of Shares or payment of cash pursuant to any Share Award is expressly subject to this Section 7.

Notwithstanding any other provision of this Plan, grants of Awards to Participants who are subject to United States federal income taxation ("U.S. Taxpayers") under the United States Internal Revenue Code of 1986, as amended (the "Code"), shall be made and administered under the terms of Schedule A to this Plan.

Subject to Section 6(i)(i) hereof, the right to receive payment pursuant to an Incentive Award or Shares pursuant to a Share Award granted to a Service Provider is personal to such Service Provider. Except as otherwise provided in this Plan, no assignment, sale, transfer, pledge or charge of an Award, whether voluntary, involuntary, by operation of law or otherwise, vests any interest or right in such Award whatsoever in any assignee or transferee and, immediately upon any assignment, sale, transfer, pledge or charge or attempt to assign, sell, transfer, pledge or charge, such Award shall terminate and be of no further force or effect.

The rights and obligations hereunder and under any Award Agreement may be assigned by the Corporation to a Successor.

If the Corporation enters into any transaction or series of transactions, other than a transaction that is a Change of Control and to which Section 6(d)(i)(III) or 6(d)(ii)(III), as the case may be, hereof apply, whereby the Corporation or All or Substantially All of the Assets would become the property of any other trust, body corporate, partnership or other person (a "Successor") whether by way of takeover bid, acquisition, reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, then prior to or contemporaneously with the consummation of such transaction:

(a) the Corporation and the Successor will execute such instruments and do such things as the Committee may determine are necessary to establish that upon the consummation of such transaction the Successor will have assumed the covenants and obligations of the Corporation under this Plan and the Award Agreements outstanding on consummation of such transaction and such Successor shall succeed to, and be substituted for, and may exercise every right and power of, the Corporation under this Plan and such Award Agreements with the same effect as though the Successor had been named as the Corporation herein and therein and thereafter, the Corporation shall be relieved of all obligations and covenants under this Plan and such Award Agreements and the obligation of the Corporation to the Participants in respect of the Awards shall terminate and be at an end and the Participants shall cease to have any further rights in respect thereof including, without limitation, any right to acquire or receive Shares on the Vesting Date(s) applicable to such Awards; or

(b) if the Awards (and the covenants and obligations of the Corporation under this Plan and the Award Agreements outstanding on consummation of such transaction) are not so assumed by the Successor, then the Vesting Date for all Shares awarded pursuant to such Awards that have not yet been issued as of such time shall be the date which is immediately prior to the date upon which the transaction is consummated.

This Plan and any Awards granted pursuant to this Plan may, subject to any required approval of the Exchange, be amended, modified or terminated by the Board without the approval of Shareholders. Without limitation of the foregoing, such amendments include, without limitation: (a) amendments of a "housekeeping nature", including, without limitation, amending the wording of any provision of this Plan for the purpose of clarifying the meaning of existing provisions or to correct or supplement any provision of this Plan that is inconsistent with any other provision of this Plan, correcting grammatical or typographical errors and amending the definitions contained within this Plan respecting the administration of this Plan; (b) amending Awards under this Plan, including with respect to the Expiry Date (provided that the term of the Award does not exceed ten years from the date the Award is granted and that such Award is not held by an Insider), vesting period, and effect of termination of a Participant's employment or cessation of the Participant's service; (c) accelerating vesting; or (d) amendments necessary to comply with applicable law or the requirements of any Exchange on which the Shares are listed. Notwithstanding the foregoing, this Plan or any Award may not be amended without Shareholder approval to:

(a) increase the number of Shares reserved for issuance pursuant to Awards in excess of the limit prescribed in Section 5 hereof;

(b) extend the Vesting Date of any Awards issued under this Plan to an Insider beyond the latest Vesting Date specified in the Award Agreement (other than as permitted by the terms and conditions of this Plan);

(c) extend the Expiry Date of any Award granted to an Insider (other than as permitted by the terms and conditions of this Plan);

(d) permit a Participant to transfer Awards to a new beneficial holder other than for estate settlement purposes;

(e) reduce the limitations on Awards contained in the first paragraph of Section 6(c) hereof;

(f) increase the number of Shares that may be issued to Insiders above the restrictions contained in Section 6(c) hereof; and

In addition, no amendment to this Plan or any Awards granted pursuant to this Plan may be made without the consent of a Participant if it adversely alters or impairs the rights of such Participant in respect of any Award previously granted to such Participant under this Plan.

(a) Interpretation - In this Plan: (a) words in the singular include the plural and words in the plural include the singular; (b) words importing the masculine gender shall include the feminine and neuter genders and vice versa; (c) section and subsection headings contained herein are for convenience only and shall not affect the construction hereof; and (d) words "hereto", "herein", "hereby", "hereunder", "hereof" and similar expressions mean or refer to this document as a whole and not to any particular Section, paragraph or other part hereof.

(b) Compliance with Legal Requirements - The Corporation shall not be obliged to issue any Shares pursuant to any Award if such issuance would violate any law or regulation or any rule of any government authority or Exchange. The Corporation, in its sole discretion, may postpone the issuance or delivery of Shares under any Award as the Committee may consider appropriate, and may require any Participant to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations. The Corporation shall not be required to qualify for resale pursuant to a prospectus or similar document any Shares awarded under this Plan, provided that, if required, the Corporation shall notify the Exchange and any other appropriate regulatory bodies in Canada and the United States of the existence of this Plan and the granting of Awards hereunder in accordance with any such requirements.

(c) Foreign Participants - The Corporation may, without amending this Plan, modify the terms of Awards granted to Service Providers who provide services to the Corporation or any member of the HEI Group from outside of Canada in order to comply with the applicable laws of such foreign jurisdictions. Any such modification to this Plan with respect to a particular Service Provider shall be reflected in the Award Agreement for such Service Provider. Schedule A is incorporated herein by reference.

(d) No Right to Continued Employment or Service - Nothing in this Plan or in any Award Agreement entered into pursuant hereto shall confer upon any Participant the right to continue in the employ or service of the Corporation or any member of the HEI Group, to be entitled to any remuneration or benefits not set forth in this Plan or an Award Agreement or to interfere with or limit in any way the right of the Corporation or any member of the HEI Group to terminate a Participant's employment or service arrangement with the Corporation or any member of the HEI Group.

(e) Ceasing to be a Member of the HEI Group - Except as otherwise provided in this Plan, Awards granted under this Plan shall not be affected by any change in the relationship between or ownership of the Corporation and a member of the HEI Group.

(f) Expenses - Except as provided in Sections 7 and 11(i), all expenses in connection with this Plan shall be borne by the Corporation.

(g) Unfunded Plan - This Plan shall be unfunded. The Corporation shall not be required to segregate any assets that may at any time be represented by Shares, cash or rights thereto, nor shall this Plan be construed as providing for such segregation. Any liability or obligation of the Corporation to any Participant with respect to an Award under this Plan shall be based solely upon any contractual obligations that may be created by this Plan and any Award Agreement, and no such liability or obligation of the Corporation shall be deemed to be secured by any pledge or other encumbrance on any property of the Corporation. Neither the Corporation nor the Board nor the Committee shall be required to give any security or bond for the performance of any obligation that may be created by this Plan.

(h) Market Fluctuations - No amount will be paid to, or in respect of, a Participant under this Plan to compensate for a downward fluctuation in the price of Shares, nor will any other form of benefit be conferred upon, or in respect of, a Participant for such purpose. The Corporation makes no representations or warranties to Participants with respect to this Plan or the Awards whatsoever. Participants are expressly advised that the value of any Awards and Shares under this Plan will fluctuate as the trading price of Shares fluctuates. Further, the payment amount or number of Shares delivered to a Service Provider following the vesting of a Performance Award may fluctuate based upon the terms of the applicable Corporate Performance Measures and Payout Multiplier. In seeking the benefits of participation in this Plan, a Participant agrees to exclusively accept all risks associated with a decline in the market price of Shares and all other risks associated with the holding of Awards.

(i) Taxes - The Corporation shall not be liable for any personal income or other tax imposed on any Participant as a result of the awarding or holding of Awards, the issue or holding of Shares pursuant thereto or any other amounts or securities paid, issued or credited to a Participant under this Plan. It is the responsibility of the Participant to complete and file any tax returns which may be required under any applicable tax laws within the period prescribed by such laws. The Corporation and the Committee make no guarantees to any person regarding the tax treatment of an Award or payments made under this Plan and none of the Corporation or any of its employees or representatives shall have any liability to a Participant with respect thereto. Participants are advised to consult with their own tax advisors.

(j) Reorganization of the Corporation - The existence of any Awards or Shares corresponding to any such Awards shall not affect in any way the right or power of the Corporation or its shareholders to make or authorize any adjustment, recapitalization, reorganization or other change in the Corporation's capital structure or its business, or any amalgamation, combination, merger or consolidation involving the Corporation or to create or issue any bonds, debentures, shares or other securities of the Corporation or the rights and conditions attaching thereto or to effect the dissolution or liquidation of the Corporation or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar nature or otherwise.

(k) Participant Information - Each Participant shall provide the Corporation with all information (including personal information) required by the Corporation in order to administer this Plan. Each Participant acknowledges that information required by the Corporation in order to administer this Plan may be disclosed to the Committee or its appointed administrator and other third parties in connection with the administration of this Plan. Each Participant consents to such disclosure and authorizes the Corporation to make such disclosure on the Participant's behalf.

(l) Final Determination - Any determination, interpretation or decision by, or opinion of, the Board, the Committee or a director or officer of the Corporation made or held pursuant to the terms set out herein shall be made or held reasonably and shall be final, conclusive and binding on all parties concerned, including, but not limited to, the Corporation, the Participants and their beneficiaries and legal representatives.

Subject to Section 11(m), all rights, entitlements and obligations of Participants under this Plan and in respect of Awards are set forth in the terms hereof and the applicable Award Agreements and cannot be modified by any other documents, statements or communications, except by amendment to the terms hereof or thereof in accordance with Section 10.

(m) Discretionary Relief - Notwithstanding any other provision hereof but subject to applicable law and the rules of any government authority or Exchange, the Committee may, in its sole discretion, waive any condition or provision set out herein or in any Award granted hereunder if it determines that specific individual circumstances warrant such waiver.

(n) Currency - All values to be determined or amounts paid under this Plan shall be in Canadian dollars.

Each member of the Board or Committee or any director or officer who is delegated the whole or any part of the administration of this Plan pursuant to Section 3 is indemnified and held harmless by the Corporation against any cost or expense (including any sum paid in settlement of a claim with the approval of the Corporation) arising out of any act or omission to act in connection with the terms hereof to the extent permitted by applicable law. This indemnification is in addition to any rights of indemnification a Board or Committee member or any director or officer who is delegated the whole or any part of the administration of this Plan pursuant to Section 3 may have as director or officer or otherwise under the by-laws of the Corporation, any agreement, any vote of shareholders or disinterested directors, or otherwise..

The validity, construction and effect of this Plan and any actions taken or relating to this Plan shall be governed by and construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein.

(a) Notwithstanding any other provision of the Plan, grants of Awards to Participants who are U.S. Taxpayers under the Code or any successor thereto, shall be made and administered under the terms of this Schedule A to the Plan.

(b) Upon the vesting of a Share Award granted to a U.S. Taxpayer, the Participant shall automatically and without any required action on his or her behalf exercise and the Corporation shall issue from treasury to the Participant the number of Shares required to be delivered upon the vesting and exercise of such Participant's Share Awards and upon the vesting of an Incentive Award granted to a U.S. Taxpayer, the Corporation shall settle the Incentive Award Value by payment or delivery to the Participant the cash and/or Shares required to be delivered upon the vesting of such Participant's Awards, in each case not later than March 15 of the year following the year in which the Vesting Date of such Award occurs (the "Payment Date"), except as otherwise provided in this Schedule A; provided however the Committee may determine that the Award will otherwise be designed on the grant date to comply with section 409A of the Code.

(c) In the event that an Award grant is amended, no such amendment shall be effective if it results in a postponement of the Vesting Date or the Payment Date, other than postponement on account of a Black-Out Period.

(d) In the event of a Change of Control, the Vesting Date of the then unvested portion of an Award granted to a U.S. Taxpayer shall be the date determined by the Board, and in the case of Share Awards the Participant shall exercise and the Corporation shall issue from treasury to the Participant the number of Shares required to be delivered upon the vesting and exercise of such Participant's Share Awards and in the case of Incentive Awards the Corporation shall settle the Incentive Award Value by payment or delivery to the Participant the cash and/or Shares required to be delivered to the Participant upon the vesting of such Participant's Share Awards, in each case by the Payment Date.

(e) The Board or Committee, as the case may be, shall interpret and construe the Plan and take all authorized actions with respect to any U.S. Taxpayer in a manner that is consistent with applicable U.S. Treasury regulations and other guidance issued pursuant to Section 409A of the Code. However, neither the Board, the Committee, the Corporation nor any other person connected with the Plan in any capacity makes any representation, commitment, or guarantee that any tax treatment shall be applicable with respect to any grant of Awards, any amounts deferred under this Plan, or any amounts paid to any person hereunder.

(f) No Participant who is a U.S. Taxpayer shall be eligible for Retirement treatment.

(a) Shares issued pursuant to the Plan shall not be issued under the Plan to a Participant unless the issuance of those securities shall comply with all relevant laws, including, the U.S. Securities Act, applicable state securities laws, and the requirements of any Exchange or automated inter-dealer quotation system in the United States upon which the Shares may then be listed or quoted, if applicable. The issuance shall also be subject to the approval of counsel for the Corporation with respect to such compliance, including the availability of an exemption from registration for the issuance of any Shares issued pursuant to the Plan. The unavailability of an exemption from registration for the issuance to a Participant of any Shares issued pursuant to the Plan or the inability of the Corporation to obtain from any regulatory body the authority deemed by the Corporation to be necessary for the lawful issuance and sale of any Shares under the Plan, shall relieve the Corporation of any liability for not issuing Shares to the Participant.

(a) The Plan and all Awards granted hereunder are subject to any written clawback policies that the Corporation, with the approval of the Board or an authorized committee thereof, may adopt either prior to or following the effective time, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the United States Securities and Exchange Commission and that the Corporation determines should apply to Awards. Any such policy may subject a Participant's Awards and amounts paid or realized with respect to Awards to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Corporation's material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy.
