 COMMON SHARE PURCHASE AGREEMENT 
  
 THIS COMMON SHARE PURCHASE AGREEMENT, dated effective as of November 4, 2005 (“Agreement”), between
CHESAPEAKE ENERGY CORPORATION, an Oklahoma corporation (the “Purchaser”) and GASTAR EXPLORATION LTD., an Alberta corporation (the “Company”). 
  
 WITNESSETH: 
  
 WHEREAS, subject to the terms and conditions of this Agreement, the Company desires to obtain additional equity funding, and the Purchaser desires to make
an investment in the Company; 
  
 NOW, THEREFORE, in consideration
of the premises and of the representations, warranties and covenants herein contained, the parties hereby agree as follows: 
  
 1. Purchase and Sale. 
  
 1.1 Consideration. The Company hereby agrees to issue and sell to the Purchaser 27,151,641 common shares (the “Shares”),
without par value, of the Company (“Common Shares”), and the Purchaser hereby agrees to purchase the Shares for a per share purchase price equal to the lesser of (the “Purchase Price”): (a) CDN $3.31 per Share, or
(b) the greater of (i) average per share closing price of the Common Shares on the Toronto Stock Exchange for the three (3) trading days immediately preceding the date of Closing or (ii) CDN $3.15 per Share. The Purchase Price
will be payable by wire transfer of immediately available funds at the closing of the transactions contemplated by this Agreement and the Related Agreements (as hereinafter defined) by the parties hereto (the “Closing”). All references in
this Agreement to “dollars” or “$” shall mean the lawful money of the United States of America, unless otherwise specifically identified as “CDN $” or “Canadian dollars”. The computation of the Purchase Price
in Canadian currency shall be converted, if necessary, into U.S. dollars using the mid-range rate for the purchase of Canadian dollars at the close of business on the business day immediately preceding the date of determination in New York,
New York as published in the New York edition of The Wall Street Journal. 
  
 1.2 Authorization. The Company agrees that the Shares to be issued and sold to the Purchaser shall be duly authorized and issued,
and shall be fully paid, nonassessable and shall not be subject to any fees, encumbrances, pledges or “adverse claims” (as Section 8.102(a)(1) of the Uniform Commercial Code of the State of Oklahoma defines that term), and upon
delivery to the Purchaser will vest full, valid and legal title to the Shares in the Purchaser. 
  
 1.3 Preemptive Rights. The Company hereby grants to the Purchaser the preemptive right to acquire a percentage of any additional
common shares, or debt or equity securities convertible into common shares (collectively, “Preemptive Right Securities”) the Company may issue such that, if such right is exercised, Purchaser would own, immediately following such issuance,
the same percentage of the outstanding Common Shares owned by the Purchaser as the percentage owned by Purchaser immediately preceding any such issuance (assuming for purposes of calculating percentages the conversion of all outstanding convertible
equity securities or debt owned by the Purchaser or issued by the Company and the exercise of all outstanding warrants, options or other rights to acquire Common Shares owned by the Purchaser or issued by the Company) (the “Purchaser’s Pro
Rata Amount”) provided, however, that the number of shares issuable to the Purchaser shall not exceed the amount which would require shareholder approval under the principal securities exchange for the Company’s common shares. This
preemptive right shall terminate in the event the Purchaser holds less than 10% of the outstanding Common Shares of the Company. This preemptive right shall also terminate on the fourth anniversary of the approval for listing of the Common Stock on
the NASDAQ National Market, the New York Stock Exchange or the American Stock Exchange (the “Listing Exchange”); provided, however, in the event the Common Stock at any time thereafter shall not be listed on the Listing
Exchange or on another nationally recognized securities exchange, the preemptive rights shall be reinstated, subject to any other independent basis for termination (including as provided in the immediately preceding sentence). This preemptive right
shall not apply to: (i) securities of the Company issued or sold pursuant to the agreements or warrants set forth on Schedule 3.2; (ii) the issuance of capital stock or warrants, options or other rights to acquire capital stock
currently outstanding or that may hereafter be granted by the Company to any 

  

 COMMON SHARE PURCHASE
AGREEMENT 
 1 

 
officer, employee, consultant or director under any existing or future option plan, incentive plan or other benefit plan of the Company or under any option,
warrant or other right to acquire capital stock that is or has been approved by the shareholders of the Company; (iii) securities of the Company issued in connection with the acquisition of oil and gas properties or other oil and gas assets or
the equity interests of any entity owning such assets; or (iv) with respect to a merger, plan of exchange or other combination involving the Company that requires the approval of the shareholders of the Company and with respect to which such
approval is obtained. Subject to the other provisions of this Section 1.3, upon the issuance by the Company of Preemptive Right Securities, the Purchaser shall have the right to purchase the Purchaser’s Pro Rata Amount of the Preemptive
Right Securities for the same cash purchase price and on the same terms as the other purchasers of such Preemptive Right Securities, except in the case of an underwritten public offering of securities registered under the Securities Act of 1933, as
amended (the “Securities Act”) or the securities legislation and regulations of the securities regulatory authorities (including the Toronto Stock Exchange) of any applicable jurisdiction, or jurisdictions collectively, in Canada (the
“Canadian Securities Laws”), in which case the Purchaser’s purchase price shall be the cash purchase price at which the Preemptive Right Securities are offered to the public. Upon receipt of written notice from the Company of the
Company’s intent to issue Preemptive Right Securities, the Purchaser shall provide written notice to the Company of its intent to exercise or not to exercise its preemptive rights within 10 days of the Purchaser’s receipt of such notice
from the Company. Failure of the Purchaser to provide notice within such 10 days shall be deemed to be a waiver of such preemptive rights. Any issuance of Preemptive Right Securities for cash not completed within 90 days of the date notice is
provided by the Company to the Purchaser as provided in the preceding sentence hereof shall be deemed to be a new issuance of Preemptive Right Securities to which this subparagraph applies. 
  
 1.4 Registration Rights Agreement. Simultaneous with
the Closing, the Company and the Purchaser will enter into a Registration Rights Agreement in substantially the form of Exhibit A attached hereto (the “Registration Rights Agreement”). 
  
 1.5 Observation and Information Rights. So long as
the Purchaser owns at least five percent (5%) of the outstanding capital shares of the Company and no Purchaser representative is serving as a member of the Company’s board of directors, the Purchaser will have the right to designate one
representative of the Purchaser to attend and observe all meetings of the board of directors of the Company, all meetings of committees of such board and all meetings of the board of directors of each of the subsidiaries of the Company. Subject to
the confidentiality provisions and other restrictions set forth below, the Company will provide such designated observer with all notices, materials and information provided to any of the members of the boards of directors or committees at the same
time as such notices, materials and information are provided to the directors including, without implied limitation, any written consent by the directors and any notices, material or information regarding such written consent. The Company will
promptly pay or reimburse each such designated observer for all reasonable out-of-pocket expenses incurred in connection with attending board or committee meetings of the Company or any subsidiary. The parties agree that the designated observer will
leave for that portion of any meeting where outside legal counsel is discussing any legal matter with the board of directors in a situation where the presence of the observer is, in the reasonable opinion of such counsel, potentially able to impair
the successful assertion of the attorney client privilege with respect to the matter being so discussed. The Purchaser will, and will cause its designated observer to, (i) maintain the confidentiality of all material nonpublic information
disclosed to either of them pursuant to the foregoing provisions and (ii) refrain from trading in shares of Common Shares or any other securities of the Company while in possession of any such material nonpublic information. 
  
 2. The Closing. 
  
 2.1 Closing Date. The Closing shall take place at the
offices of the Purchaser at 6100 North Western Avenue, Oklahoma City, Oklahoma on November 4, 2005 and upon all of the conditions precedent set forth in Section 6 of this Agreement having been satisfied (the “Closing Date”).

 2.2 Payment and Delivery. At the Closing, the Purchaser shall pay the Purchase
Price by transferring immediately available funds by wire transfer to the Company. At the Closing, the Company will deliver to the Purchaser certificates representing the Shares. The certificates for Shares shall be subject to a legend restricting
transfer under the Securities Act, and referring to restrictions on transfer therein, such legend to be substantially as follows: 
  
 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AS TO THE AVAILABILITY OF AN EXEMPTION FROM REGISTRATION THAT SUCH REGISTRATION IS NOT REQUIRED AND THAT ANY
PROSPECTUS DELIVERY REQUIREMENTS ARE NOT APPLICABLE. 
  
 The Shares may also
include any legend required under the laws of any state, province or other jurisdiction and will include a legend required under the Canadian Securities Laws, substantially as follows: 
  
 UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [insert the
date that is 4 months and a day after the distribution date]. 
  
 THE SECURITIES HEREIN ARE SUBJECT TO THE RESALE RESTRICTIONS SET OUT IN SECTION 3.2 OF ALBERTA SECURITIES COMMISSION RULE 72-501. 
  
 The foregoing legends will be removed and the Company will issue replacement certificates without such legends upon registration of the Shares and in accordance with
applicable law including the Canadian Securities Laws. 
  
 3.
Representations and Warranties of the Company. The Company represents and warrants to the Purchaser that, as of the date of this Agreement: 
  
 3.1 Organization and Existence. The Company is a corporation duly continued and validly existing and in good standing under the
laws of Alberta, Canada and has all requisite corporate power to carry on its business as now conducted and is qualified to do business in those jurisdictions where its ownership, lease or use of property or the conduct of its business requires such
qualification. The Company has delivered to the Purchaser complete and correct copies of the Articles of Incorporation and Bylaws of the Company as in effect on the date hereof. 
  
 3.2 Capitalization: Ownership of Shares: Authorization. The Company has an unlimited number of
authorized Common Shares and no authorized or issued shares of preferred shares. As of the date of this Agreement, the Company had (a) 136,440,407 issued and outstanding Common Shares; (b) no treasury shares; and (c) $30,000,000 of
9.75% convertible senior unsecured debentures outstanding that may be converted into 6,849,315 underlying Common Shares. The Company is obligated pursuant to its Senior Secured Notes to issue to the purchasers of the Senior Secured Notes, for no
additional consideration, additional shares in increments valued at CDN $4,500,000 on each of the six, twelve, and eighteen-month anniversaries of the initial closing of June 17, 2005, valued on a five-day weighted average trading price
immediately prior to the date of issuance. Additionally, the Company is obligated pursuant to its Senior Secured Notes to issue to the purchasers of the Senior Secured Notes, for no additional consideration, additional shares in increments valued at
CDN $714,286 on each of the six, twelve and eighteen-month anniversaries of the second closing of September 19, 2005, valued on a five-day weighted average trading price immediately prior to the date of issuance. In addition as of
October 5, 2005, the Company had (i) issued warrants to purchase up to 2,992,261 Common Shares, and (ii) authority to grant up to 25,000,000 options exercisable for Common Shares pursuant to stock option plans which have been approved
by the Company’s shareholders, of which 17,425,850 share options were outstanding. There are 17,520,850 share options outstanding as of the date hereof. Other than the registration rights granted to the Purchaser in accordance with the
transactions contemplated hereby, the Company has granted only the registration rights more particularly described in Schedule 3.2 that are currently in effect, including demand or piggy-back registration rights. Except as set forth in this
Section 3.2, there are no other options, warrants, rights, conversion rights, phantom rights, preemptive rights or any other rights of any party to receive equity of the Company. Upon issuance of the Shares to the Purchaser, the Purchaser will
be the record and beneficial owner of the Shares and the Shares will be duly authorized, validly issued and outstanding, fully paid and nonassessable. As a result of the issuance of the Shares, the Company is not, nor will it become, obligated to
issue any additional shares of capital stock (preferred or common) to any officer, director, shareholder or other party.

 3.3 No Conflicts. The execution and delivery of this Agreement and the
Registration Rights Agreement by the Company and the execution and delivery of the Related Agreements by the Company and certain of its subsidiaries, and performance by the Company and its subsidiaries hereunder and thereunder, will not result in a
violation or breach of any term or provision of or constitute a default or accelerate the performance required under (i) the Articles of Incorporation, Bylaws or other governance documents of the Company or any of its subsidiaries or
(ii) any material indenture, mortgage, deed of trust or other contract or agreement to which the Company or any of its subsidiaries is a party or by which their respective assets are bound, or violate any statute, rule, regulation, order, writ,
injunction or decree of any court, administrative agency or governmental body, except for any violation, breach or default that would not have a Material Adverse Effect. 
  
 3.4 Authority; Enforceability. The Company has full right, power and authority to execute and deliver
this Agreement, the Registration Rights Agreement and the Related Agreements and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement, the Registration Rights Agreement and the Related
Agreements and the consummation of the transactions contemplated hereby to be performed by the Company have been duly and validly authorized by all necessary corporate action on the part of the Company, and no other corporate proceedings are
necessary to authorize the execution and delivery of this Agreement, the Registration Rights Agreement and the Related Agreements by the Company or to consummate the transactions contemplated hereby to be performed by the Company. This Agreement,
the Registration Rights Agreement and the Related Agreements constitute valid and legally binding obligations of the Company, enforceable in accordance with their respective terms, except as that enforcement may be limited by bankruptcy, insolvency,
moratorium or similar laws affecting the enforcement of creditors’ rights, by the availability of injunctive relief or specific performance and by general principles of equity and, in the case of the Registration Rights Agreement, any rights to
indemnity or contribution thereunder may be limited by federal and state securities laws and public policy considerations. 
  
 3.5 Litigation; Contingencies. Except as described in Schedule 3.5, there is no action, suit or proceeding pending or, to
the knowledge of the Company, threatened against the Company or any of its subsidiaries before any court, agency or arbitrator that would result in any Material Adverse Effect or that questions the validity of any action taken or to be taken
pursuant to or in connection with this Agreement, the Registration Rights Agreement or the Related Agreements. As used in this Agreement, the term “Material Adverse Effect” shall mean an event, circumstance, loss, development or effect
that would result in a material adverse effect on the business, operations, assets, financial condition or results of operations of the Company and its subsidiaries. 
  
 3.6 Subsidiaries. Except for the subsidiaries listed in Schedule 3.6 attached hereto, the
Company has no subsidiaries or any material equity interests in any other corporation, partnership, limited liability company, joint venture or other entity (excluding joint ventures, joint operating or ownership arrangements and tax partnerships

duly organized and is in good standing under the laws of the jurisdiction of its organization, with power and authority (corporate and other) to own its properties and conduct its business; and each subsidiary of the Company is duly qualified to do
business and is in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified or in good standing would not reasonably
be expected to individually or in the aggregate have a Material Adverse Effect. All of the issued and outstanding capital stock or similar equity interests of each subsidiary of the Company has been duly authorized and validly issued and is fully
paid and nonassessable; and the capital stock or similar equity interests of each subsidiary owned by the Company, directly or through subsidiaries, are owned free from liens, encumbrances and defects, except as provided in Schedule 3.7.

  
 3.7 Title to Assets. Except as
otherwise set forth in Schedule 3.7, the Company and its subsidiaries have: (i) defensible title to its oil and gas properties, title investigation having been carried out by the Company in accordance with the practice in the oil and gas
industry in the areas in which the Company operates and (ii) good and defensible title to all other material real properties and all other material properties and assets owned by them, in each case, except for Permitted Encumbrances, free from
liens, encumbrances and defects that would materially affect the value thereof taken as a whole or materially interfere with the use made or to be made thereof by them as a whole. The Company and its subsidiaries have maintained all their tangible
personal properties material to the business of the Company and its subsidiaries, taken as a whole, in good repair, working order and

operating condition, subject to ordinary wear and tear, and all such assets are suitable for the purposes for which they are presently being used, except
where the failure to have such would not be reasonably expected to have a Material Adverse Effect. The Company and its subsidiaries have all easements, rights-of-way and similar authorizations required for the use of the real properties and all
other properties and assets owned by them and used in the conduct of the business as heretofore conducted except where the failure to have such would not be reasonably expected to have a Material Adverse Effect. No material properties or assets of
the Company and its subsidiaries, or any portion thereof, has been condemned or otherwise taken by any public authority, and neither the Company nor any of its subsidiaries has received written notice that any such condemnation or taking is
threatened or contemplated. “Permitted Encumbrances” as used herein shall mean any or all of the following: (a) encumbrances that arise under operating agreements to secure payment of amounts not yet delinquent and are of a type and
nature customary in the oil and gas industry; (b) encumbrances that arise as a result of pooling and unitization agreements, declarations, orders, or laws to secure payment of amounts not yet delinquent; (c) encumbrances securing payments
to mechanics and materialmen or securing payment of taxes or assessments that are, in either case, not yet delinquent; (d) lessor’s royalties, overriding royalties, division orders, reversionary interests and other similar burdens that do
not operate to materially reduce the value of the property affected; (e) easements, rights-of-way, servitudes, permits, surface leases, surface use restrictions and other surface uses and impediments on, over or in respect of any of the assets,
provided that they do not interfere materially with the ownership, operation, value, or use of the property affected; (f) rights reserved to or vested in any governmental entity, to control or regulate any of the assets in any manner, and all
applicable laws, of any governmental entity; (g) production sales contracts; contracts for sale, purchase, exchange, refining or processing of hydrocarbons; farm-out or farm-in agreements; participation agreements; unitization and pooling
designations, declarations, orders and agreements; agreements of development; area of mutual interest agreements; gas balancing and deferred production agreements; plant agreements; production handling agreements; processing agreements; pipeline,
gathering and transportation agreements; injection, repressuring and recycling agreements; carbon dioxide purchase or sale agreements; and salt water or other disposal agreements, (in each case) to the extent the same are ordinary and customary to
the oil, gas and other mineral exploration, development, processing or extraction business. 
  
 3.8 Consents. Except as otherwise set forth in Schedule 3.8, the Company is not required to obtain any consent from or
approval of any court, governmental entity or any other person in connection with the execution, delivery or performance by it of this Agreement, the Registration Rights Agreement or the Related Agreements and the transactions contemplated hereby
and thereby, except such filings as may be required to be made with the Securities and Exchange Commission (“SEC”), pursuant to the Canadian Securities Laws and/or the Toronto Stock Exchange and with any state or foreign “blue
sky” or securities regulatory authority. Except as otherwise set forth in Schedule 3.8, the consummation of the transactions contemplated by this Agreement will not require the approval of any entity or person in order to prevent the
termination of any material right, privilege, license or agreement of the Company. 
  
 3.9 Proprietary Rights. Except as set forth on Schedule 3.9, the Company and its subsidiaries own or possess adequate
licenses or other valid rights to use all patents, patent rights, trademarks, trademark rights and proprietary information used or held for use in connection with their respective businesses as currently being conducted, except where the failure to
own or possess such licenses and other rights would not have a Material Adverse Effect, and there are no assertions or claims challenging the validity of any of the foregoing that would have a Material Adverse Effect. The conduct of the
Company’s and its subsidiaries’ respective businesses as currently conducted does not conflict with any patents, patent rights, licenses, trademarks, trademark rights, trade names, trade name rights or copyrights of others in any way that
would have a Material Adverse Effect. There is no infringement of any proprietary right owned by or licensed by or to the Company or any of its subsidiaries that would have a Material Adverse Effect. 
  
 3.10 Reports; Financial Statements. The Company has
filed all reports, schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to any applicable reporting requirements of the 1934 Act, if any, or to be filed by it under the Canadian Securities Laws (all of
the foregoing filed prior to the date this representation is made (including all exhibits included therein and financial statements and schedules thereto and documents incorporated by reference therein) being herein referred to as the
“Reports”). The Company has made available to the Purchaser true and complete copies of all Reports filed since October 15, 2003. As of their respective dates, the Reports complied in all material respects with the requirements of the
laws, rules and regulations applicable to thereto. None of the Reports, at the time they were filed with the SEC or under 

  

 COMMON SHARE PURCHASE
AGREEMENT 
 5 

 
Canadian Securities Laws, as applicable, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. As of their respective dates, the consolidated financial statements of the Company and its subsidiaries included in the
Reports and in the Company’s registration statement on Form S-1 and any amendment thereto filed with the SEC under the Securities Act (the “Form S-1”) complied as to form in all material respects with applicable accounting
requirements and the published securities laws, rules and regulations applicable thereto. Such consolidated financial statements have been prepared in accordance with U.S. or Canadian generally accepted accounting principles (as applicable),
consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or
may be condensed or summary statements) and fairly present in all material respects the financial position of the Company and its subsidiaries as of the dates thereof and the results of their operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit adjustments). Except as set forth on Schedule 3.10, all of the financial statements present fairly in all material respects the financial position and the results of
operations of the Company and its subsidiaries as of the dates and for the periods shown therein, and to the knowledge of the Company, there has been no Material Adverse Effect on the financial condition of the Company since June 30, 2005.
Except as set forth on Schedule 3.10, neither the Company nor any of its subsidiaries has any debt, liability or obligation, contingent or otherwise, that would have a Material Adverse Effect. The accounting firm that has expressed its
opinion with respect to the consolidated financial statements included in the Company’s most recently filed annual Report and the Form S-1 is independent of the Company as required under the Canadian Securities Laws or pursuant to the standards
promulgated by the SEC in Rule 2-01 of Regulation S-X, as applicable, and such firm was otherwise qualified to render the audit opinion under applicable laws. There is no transaction, arrangement or other relationship between the Company and an

 COMMON SHARE PURCHASE
AGREEMENT

contemplated hereby and thereby. The execution and delivery of this Agreement and the Registration Rights Agreement and the consummation of the transactions
contemplated hereby and thereby to be performed by the Purchaser have been duly and validly authorized by all necessary corporate action on the part of the Purchaser, and no other corporate proceedings are necessary to authorize the execution and
delivery of this Agreement and the Registration Rights Agreement by the Purchaser or to consummate the transactions contemplated hereby to be performed by the Purchaser. This Agreement and the Registration Rights Agreement will constitute valid and
legally binding obligations of the Purchaser, enforceable in accordance with their respective terms, except as that enforcement may be limited by bankruptcy, insolvency, moratorium or similar laws affecting the enforcement of creditors’ rights,

person in connection with the execution, delivery or performance by it of this Agreement or the Registration Rights Agreement and the transactions contemplated hereby. The consummation of the transactions contemplated by this Agreement will not

in the Company. The Purchaser acknowledges that it has had, or will have prior to Closing, the opportunity to ask questions of the officers of the Company. The Purchaser is an informed and sophisticated purchaser, experienced in the evaluation and
purchase of interests in companies such as the Company as contemplated hereunder. The Purchaser has or will have undertaken such investigation and has or will have evaluated such documents and information as it has deemed necessary to enable it to

of this Agreement. Any party may give the other party written notice of any dispute not resolved in the normal course of business. Within 15 days after delivery of the notice, the receiving party shall submit to the other party a written response.
The notice and response shall include (a) a statement of that party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive who will represent that party and of any other person who
will accompany the executive. Within 30 days after delivery of the initial notice, the executives of both parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve
the dispute. All reasonable requests for information made by one party to the other will be honored. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable
rules of evidence. 
  
 (b) If the dispute has not
been resolved by negotiation as provided herein within 45 days after delivery of the initial notice of negotiation, the parties shall endeavor to settle the dispute by mediation under the CPR Mediation Procedure in effect on the date of this
Agreement, provided, however, that if one party fails to participate in the negotiation as provided herein, the other party can initiate mediation prior to the expiration of the 45 days. Unless otherwise agreed, the parties will select a mediator
from the CPR Panels of Distinguished Neutrals. 
  
 (c) Any dispute arising out of or relating to this Agreement, including the breach, termination or validity thereof, that has not been resolved by mediation as provided herein within 45 days after initiation of the mediation procedure,

CPR Rules for Non-Administered Arbitration in effect on the date of this Agreement, by three independent and impartial arbitrators, of whom each party shall
designate one; provided, however, that if one party fails to participate in either the negotiation or mediation as agreed herein, the other party can commence arbitration prior to the expiration of the time periods set forth above. The arbitration
shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction thereof. The place of arbitration shall be Houston, Texas. The
arbitrators are not empowered to award damages in excess of compensatory damages and each party expressly waives and foregoes any right to punitive, exemplary or similar damages unless a statute requires that compensatory damages be increased in a
specified manner. 
  
 (d) Each party is required
to continue to perform its obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement, unless to do so would be impossible or impractical. 
  
 7.11 Attorney Fees. Without limiting the
arbitrators’ right to award costs and/or attorneys’ fees pursuant to Section 7.10 hereof, if any action at law or in equity is brought to secure injunctive relief, enforce an arbitration award or, subject to Section 7.10 hereof,
enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which it may be entitled. 
  
 7.12 Severability. In case any one or more of the
provisions contained in this Agreement or any application thereof shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and other applications thereof shall
not in any way be affected or impaired thereby.

 Affiliate Transactions 
  

	(a)	In 2001, the Company entered into a Participation and Operating Agreement (“POA”) with Geostar. Pursuant to the terms of the agreement, the Company has the option to
participate as a working interest partner in properties in which Geostar and its subsidiaries have interests in on an “at cost” basis, subject to Gastar’s full due diligence review, prior to its participation election. Upon agreeing
to participate, the Company is responsible for its proportionate share of actual costs expended by Geostar and its subsidiaries to various arms length parties on an “at cost” basis. The balance of $600,811 at December 31, 2004 and
$38,930 at December 31, 2003, represents amounts owed to Geostar and its subsidiaries for oil and gas property development. The 2003 balance was settled in 2004 via a cash payment. Of the total revenue receivable on the first-quarter 2005
balance sheet, $3,040,552 represents amounts that will be owed from Geostar once it receives the revenue from the third party gas purchaser. These amounts were settled subsequent to the end of the first quarter 2005. At June 30, 2005, there is
a balance of $858,000 receivable from Geostar related to the revenue earned from the properties net of capitalized expenditures incurred during the period and net of the estimated post closing adjustments. This amount, along with the final
post-closing purchase price adjustments, will be settled as provided for in the Purchase and Sale Agreements between Geostar and the Company. 

  

	(b)	On June 1, 2000, the Company entered into an agreement with Geostar, a significant shareholder, to settle accounts payable related to the development of oil and gas properties
with the issuance of a floating convertible debenture for up to CDN $25 million. Under the agreement, Geostar would continue to provide funds for development and operations by allowing the Company to draw down on the debenture. Advances under the
debenture would be subject to Geostar’s availability of funds and the approval of the requested advances by Geostar’s board of directors. The debenture was payable in cash or could be converted into shares at prevailing market prices at
the option of the Company. Effective January 1, 2005, pursuant to the Joint Operating Agreement (defined in (e) below) with Geostar, the Company cancelled this convertible debenture agreement. 

  

	(c)	In 2004, pursuant to the terms of the POA, Geostar also billed the Company $27,000 (2003 - $369,371) for administrative overhead based on current independent, third-party,
industry billing rates for similar services within the same project area. 

  

	(d)	In 2004, First Sourcenergy Wyoming, Inc. (“FSW”) recorded $1,326,916 (2003 - $Nil) in general and administrative costs for administrative and technical support
provided by Geostar to the Company. Commencing April 1, 2004, FSW and Geostar agreed to replace the administrative fee with a cost sharing arrangement. As a result, Geostar will charge FSW a proportionate amount of direct salary and shared
premises rent expense for Geostar employees providing administrative and technical support services to Gastar based on actual costs incurred. This cost sharing arrangement is expected to continue as long as Geostar is the operator of the
jointly-owned properties. This arrangement resulted in a charge of approximately $146,000 per month for the second and third quarter of 2004 and $150,000 per month for the fourth quarter of 2004. The consolidated statements also include
approximately $114,500 (2003 - $33,456) in seismic reprocessing fees to a subsidiary of Geostar, based on current independent, third-party industry billing rates. The seismic reprocessing fees were capitalized to oil and gas properties.

  

	(e)	Effective January 1, 2005, the Company, FSW, and Geostar entered into a Joint Operating Agreement (“JOA”) covering an Area of Mutual Interest (“AMI”) in the
East Texas Basin, with Gastar as a Non-Operator and Geostar as Operator. Under the terms of the JOA, Geostar will receive overhead reimbursement equal to 12.5% of development costs for the first 10 wells drilling after January 1, 2005, 10% of
the development costs for the 11th through 20th wells and 8.5% of the developments costs for subsequent wells. As a result, Geostar will no longer charge Gastar a proportionate amount of direct salary and
shared premises rent expense for Geostar employees providing administrative and technical support services to Gastar. 

  

 Schedule 3.23 

	(f)	Letter of Intent, dated April 15, 2005, regarding the purchase of the Powder River Basin and East Texas assets of Geostar by the Company effective January 1, 2005. Under
separate documentation the Company will enter into an agreement to purchase an option for certain coal mining rights in Victoria, Australia.

	2.	DEMAND REGISTRATION. 

  
 (a) Request for Registration. At any time after the earlier of January 1, 2006 or the date of effectiveness of the Company’s registration
statement on Form S-1 (File No. 333-127498) (the “Existing Registration Statement”), if the Company shall receive a written request (“Demand Notice”) from an Investor holding at least 30% of the Registrable
Securities then outstanding (the “Initiating Investor”) for registration under the 1933 Act (a “Demand Registration”) of all or part of its Registrable Securities but not less than 30% of the Registrable Securities
then outstanding, then the Company shall, within 15 days of the receipt thereof, give written notice of such Demand Notice to each Investor. Within 15 days after receiving such notice, each Investor may make a written request to the Company that any
or all of the Investor’s Registrable Securities be included in the Demand Registration, which notice shall specify the number of shares to be so included. Subject to Section 2(e) hereof, the Company shall include in the Demand Registration
(or in a separate Registration Statement filed concurrently therewith) all Registrable Securities with respect to which the Company has received a written request for inclusion therein within 15 days after the receipt by such Investor of the
Company’s notice. Each Investor shall be permitted to withdraw all or part of the Investor’s Registrable Securities requested to be included in the Demand Registration at any time prior to the effective date of such Demand Registration
without any liability for any registration expenses. The Demand Notice will specify the number of shares of Registrable Securities proposed to be sold and will also specify the intended method of disposition thereof and the jurisdictions in which
registration is reasonably desired. 
  
 b. Limitation on Demand
Registration. The Company shall not be obligated to effect more than three Demand Registrations under this Section 2. Notwithstanding any provision of this Agreement to the contrary, the Company shall be entitled to postpone (but not more
than once in any twelve month period), for a reasonable period of time not in excess of 90 days, the filing of a Registration Statement if the Company delivers to the Investors a certificate signed by the Chief Executive Officer or Chief Financial
Officer of the Company certifying that, in the good faith judgment of the Board of Directors of the Company, such registration and offering would reasonably be expected to materially adversely affect or materially interfere with any bona fide
material financing of the Company or any material transaction under consideration by the Company or would require disclosure of information that has not been disclosed to the public, the premature disclosure of which would materially adversely
affect the Company. Such certificate shall contain a statement of the reasons for such postponement and an approximation of the anticipated delay. The Persons receiving such certificate shall keep the information contained in such certificate
confidential subject to the same terms set forth in Section 4(i). If the 

  

 -2- 

 
Company shall so postpone the filing of a Registration Statement, the Initiating Investor shall have the right to withdraw the request for registration by
giving written notice to the Company within 10 days of the anticipated termination date of the postponement period, as provided in the certificate delivered by the Company pursuant hereto, and in the event of such withdrawal, such request shall not
be counted for purposes of the number of Demand Registrations to which the Investors are entitled pursuant to the terms of this Agreement. 
  
 c. Effective Registration. A registration will not count as a Demand Registration (i) unless a Registration Statement with respect thereto has
become effective (unless the Initiating Investor withdraws its shares of Registrable Securities requested to be included in the Demand Registration), (ii) if after it has become effective, such registration is interfered with by any stop order,
injunction or other order or requirement of the SEC or other governmental agency or court for any reason not attributable to an Investor and has not thereafter become effective, or (iii) if the conditions to closing specified in the
underwriting agreement, if any, entered into in connection with such registration are not satisfied or waived, other than by reason of a failure on the part of an Investor. 
  
 d. No Third-Party Piggy-Back on Demand Registrations without Consent. Neither the Company nor any of its security
holders who are not Investors may include securities of the Company in any Demand Registration without the prior written consent of the Initiating Investor. 
  
 e. Priority on Demand Registrations. In the event an offering pursuant to a Demand Registration shall be in the form of an underwritten offering
pursuant to subsection (f) below, if the managing underwriter or underwriters of such offering advise the Company and the Investors in writing that, in their good faith judgment, the number of Registrable Securities and any other securities
requested to be included in such offering is sufficiently large to adversely affect the success of such offering (a “Material Adverse Effect”), then (i) the amount of securities to be included in the Demand Registration
for any Persons (other than the Company and the Investors) shall first be reduced, thereafter the securities to be offered for the account of the Company shall be reduced, and thereafter the Registrable Securities to be offered for the account of
the Investors shall be reduced so that the total number of securities to be included in the offering shall be the recommended number by such managing underwriter or underwriters, unless the Investors desire to sell a number of Registrable Securities
that is less than the total amount that they are entitled to sell, in which event the number of Registrable Securities not so elected to be sold shall be allocated first to the Company and then to any other holders of securities of the Company
permitted to include their securities in such Demand Registration pursuant to Section 2(d). 
  
 f. Manner of Offering; Selection of Underwriters. If the Initiating Investor so requests, the offering of Registrable Securities pursuant to a
Demand Registration shall be in the form of an underwritten offering and all Persons electing to participate in such Demand Registration shall be bound by such determination. If a Demand Registration is in the form of an underwritten offering, the
Initiating Investor shall select the managing underwriter or underwriters to be used in connection with the offering; provided, however, that such underwriter or underwriters must be reasonably satisfactory to the Company. 

 

	3.	PIGGY-BACK REGISTRATION. 

  
 a. Request for Registration. At any time after the date hereof, if the Company proposes to file a registration statement under the 1933 Act (other than
(i) a registration statement on Form S-4 or S-8 or any successor form that may be adopted by the SEC, (ii) a registration statement filed in connection with an exchange offer or offering of securities or debt solely to the Company’s
existing security or debt holders, (iii) a registration statement filed as a “shelf” registration pursuant to Rule 415 under the 1933 Act or (iv) the Existing Registration Statement (an “Exempt Offering”)) with
respect to an offering of securities of the same class as the Registrable Securities for the Company’s own account or for the account of any of its security holders, then the Company shall give written notice of such proposed filing to each
Investor as soon as practicable (but in no event less than 20 nor more than 60 days before the anticipated filing date). Such notice shall offer each Investor the opportunity to have all or any of the Registrable Securities held by such Investor
included in the Registration Statement proposed to be filed or, at the Company’s option, in a separate Registration Statement to be filed concurrently with such Registration Statement (the “Piggy-Back Registration”). Within 15
days after receiving such notice, each Investor may make a written request to the Company that any or all of the Investor’s Registrable Securities be included in the Piggy-Back Registration, which notice shall specify the number of shares to be
so included. Subject to Section 3(b) hereof, the Company shall include in the Piggy-Back Registration (or in a separate Registration 

  

 -3- 

 
Statement filed concurrently therewith) all Registrable Securities with respect to which the Company has received a written request for inclusion therein
within 15 days after the receipt by such Investor of the Company’s notice. The Company may in its discretion withdraw any Registration Statement filed pursuant to this Section 3(a) subsequent to its filing without liability to any Investor
except with respect to expenses. Each Investor shall be permitted to withdraw all or part of the Investor’s Registrable Securities requested to be included in a Piggy-Back Registration at any time prior to the effective date of such Piggy-Back
Registration without any liability for any registration expenses. 
  
 b. Priority on Piggy-Back Registration. If any Piggy-Back Registration is to be an underwritten offering, the Company shall use its reasonable efforts to cause the managing underwriter or underwriters to permit the shares of
Registrable Securities requested by each Investor to be included in the Piggy-Back Registration (on the same terms and conditions as similar securities of the Company included therein to the extent appropriate). Notwithstanding the foregoing, if the
managing underwriter or underwriters of such offering advise the Company in writing that, in their good faith judgment, the number of Registrable Securities and any other securities requested to be included in such offering is sufficiently large to
have a Material Adverse Effect, then (i) if such Piggy-Back Registration is incident to a primary registration on behalf of the Company, the amount of securities to be included in the Piggy-Back Registration for any Persons (other than the
Company) shall be reduced pro rata so that the total number of securities to be included in the offering shall be the recommended number by such managing underwriter or underwriters, unless an Investor desires to sell a number of Registrable
Securities that is less than the total amount that it is entitled to sell, and (ii) if such Piggy-Back Registration is incident to a secondary registration on behalf of holders of securities of the Company, the Company shall include in such
Registration Statement (A) first, the number of securities of such Person(s) on whose behalf the registration is being made, (B) second, the number of Registrable Securities requested to be included in such registration pursuant to this
Section 3 and for the account of all other Persons pursuant to similar piggy-back registration rights in excess of the securities such Persons on whose behalf the registration is being made propose to sell that, in the good faith judgment of
such managing underwriters, can be sold without causing a Material Adverse Effect on such offering, and (C) third, the number of securities requested to be included in such registration by the Company. 
  
 c. Legal Counsel. Subject to Section 6 hereof, the Purchaser
shall have the right to select one legal counsel to review, on behalf of the Purchaser, any registration pursuant to this Agreement (“Legal Counsel”), which shall be Commercial Law Group, P.C., or such other counsel as thereafter
designated in writing to the Company by the Purchaser or its assignee. The Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations under this Agreement. 
  

	4.	REGISTRATION PROCEDURES. 

  
 At such time as the Company is obligated to effect the registration of the Registrable Securities with the SEC pursuant to Section 2 or 3 hereof, the
Company will use its reasonable efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations: 
  
 a. The Company shall promptly prepare and file with the SEC a Registration
Statement with respect to the applicable Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective as soon as practicable after such filing. The Company shall keep each Registration Statement
effective at all times for a period of at least 120 days after the effective date thereof or such shorter period in which all Registrable Securities included in such Registration Statement have been sold (the “Registration Period”).
Such Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary
to make the statements therein, in light of the circumstances in which they were made, not misleading. The term “reasonable efforts” shall mean, among other things, that the Company shall submit to the SEC, within three (3) Business
Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further comments on the Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request; provided, however, that, subject to Section 4(t), the Company may delay (an “Effectiveness Request Grace
Period”) such submission of a request for 

  

 -4- 

 
acceleration of effectiveness of such Registration Statement if, in the good faith opinion of the Company and its counsel, such Effectiveness Request Grace
Period is necessary to avoid disclosure of material non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best interest of
the Company and, in the opinion of counsel to the Company, otherwise required; provided that the Company shall (i) promptly notify the Investor in writing of the existence of material non-public information giving rise to such an Effectiveness
Request Grace Period (provided that in each notice the Company shall not disclose the content of such material non-public information to the Investor), (ii) submit such request for acceleration of effectiveness as soon as, in the good faith
opinion of Company and its counsel, such Effectiveness Request Grace Period is no longer necessary (subject to Section 4(t)), and (iii) notify the Investor in writing of the date on which the Effectiveness Request Grace Period ends.

  
 b. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) to each Registration Statement as may be necessary to keep such Registration Statement effective at all times during the Registration Period, with respect to the disposition of all securities covered
by the Registration Statement and cause the related Prospectus to be supplemented by any Prospectus supplement as may be necessary to comply with the provisions of the 1933 Act with respect to the disposition of the securities of the Company covered
by such Registration Statement until such time as all of such securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement and as so
supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the 1933 Act. In the case of amendments and supplements to a Registration Statement that are required to be filed pursuant to this Agreement (including
pursuant to this Section 4(b)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended (the “1934 Act”), the Company shall have
incorporated such report by reference into the Registration Statement, if applicable and permitted by law, or shall file such amendments or supplements with the SEC as soon as practicable after such filing of the report; provided,
however, that the Company may delay the filing of any applicable supplement or amendment pursuant to Section 4(t) (any such delay, a “Current Report Update Grace Period”). 
  
 c. The Company shall (A) permit Legal Counsel to review and comment upon
(i) the Registration Statement at least five (5) Business Days prior to its filing with the SEC, and (ii) all amendments and supplements to the Registration Statement (except for Annual Reports on Form 10-K, Quarterly Reports on Form
l0-Q and Current Reports on Form 8-K and any similar or successor reports) within a reasonable number of days prior to their filing with the SEC, and (B) not file any document, Registration Statement, amendment or supplement described in the
foregoing clause (A) in a form to which Legal Counsel reasonably objects. The Company shall not submit a request for acceleration of the effectiveness of the Registration Statement or any amendment or supplement thereto without providing prior
notice thereof to Legal Counsel and each Investor. The Company shall furnish to Legal Counsel, without charge, (i) promptly after the same is prepared and filed with the SEC, one copy of the Registration Statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein by reference that have not been filed, or are not immediately available electronically, via EDGAR, and all exhibits, and (ii) upon the effectiveness of any
Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto. The Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations pursuant to
this Section 4. 
  
 d. The Company shall furnish to each
Investor whose Registrable Securities are included in a Registration Statement, and to any managing underwriter or underwriters, without charge, at least one conformed copy of the Registration Statement, the Prospectus and Prospectus
supplements, if applicable, and each post-effective amendment thereto, including financial statements (but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits, unless requested in
writing by the Investor or the managing underwriter or underwriters) and deliver to the Investor, without charge, as many copies of the Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as the
Investor may reasonably request in connection with the distribution of the Registrable Securities. 
  
 e. The Company shall use its reasonable efforts to (i) register and qualify, unless an exemption from registration and qualification applies, the
resale by the Investor of the Registrable Securities covered by a 

  

 -5- 

 
Registration Statement under the securities or “blue sky” laws of all the states of the United States, (ii) prepare and file in those
jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other
actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for
sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but
for this Section 4(e) or (y) subject itself to general taxation in any such jurisdiction. The Company shall promptly notify Legal Counsel and each Investor who holds Registrable Securities of the receipt by the Company of any notification
with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the
initiation or threatening of any proceeding for such purpose. 
  
 f. The Company shall notify Legal Counsel and each Investor in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement,
as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not
misleading (provided that in no event shall such notice contain any material, nonpublic information), and promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver to each
Investor, without charge, as many copies of the Prospectus included in such Registration Statement and each amendment or supplement thereto as such Investor may reasonably request in connection with the distribution of the Registrable Securities.
The Company shall also promptly notify Legal Counsel and each Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment
has become effective (notification of such effectiveness shall be delivered electronically to Legal Counsel and each Investor on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for amendments or
supplements to a Registration Statement or related prospectus or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate. 
  
 g. The Company shall use its reasonable efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the
withdrawal of such order or suspension as soon as practicable and to notify Legal Counsel and each Investor who holds Registrable Securities being sold of the issuance of such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose. 
  
 h. At
the reasonable request (in the context of the securities laws) of any Investor, the Company shall furnish to such Investor, on the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as an Investor
may reasonably request (i) a letter, dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the Investor, and (ii) an opinion, dated as of such date, of counsel representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten
public offering, addressed to the Investor, provided that such Investor shall reimburse the Company for its out-of-pocket expenses incurred in connection with the furnishing of any such letter and opinion. 
  
 i. At the reasonable request (in the context of the securities laws) of any
Investor, the Company shall upon receipt of a waiver of such investor’s non-public information requirements make available for inspection during regular business hours by (i) any Investor, (ii) Legal Counsel and (iii) one firm of
accountants or other agents retained by the Investors (collectively, the “Inspectors”), all pertinent financial and other records, and pertinent corporate documents and properties of the Company (collectively, the
“Records”), as shall be reasonably deemed necessary by each Inspector, and cause the Company’s officers, directors and employees to supply all information that any Inspector may reasonably request; provided, however, that each
Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to an Investor and Legal Counsel) or use of any 

  

 -6- 

 
Record or other information that the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless
(a) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (b) the release of such Records is ordered pursuant to a final,
non-appealable subpoena or order from a court or government body of competent jurisdiction, or (c) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other
agreement of which the Inspector has knowledge. Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to
the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential. Each Inspector that exercises its rights under this Section 4(i)
shall be obligated to execute a non-disclosure agreement containing such reasonable terms as the Company may request. The fees and expenses of the Inspectors shall be borne by the applicable Investor or Investors. 
  
 j. The Company shall hold in confidence and not make any disclosure of
information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such
information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is
sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Investor and allow such Investor, at the Investor’s expense, to undertake appropriate action to prevent disclosure
of, or to obtain a protective order for, such information. 
  
 k.
The Company shall use its reasonable efforts to (i) maintain the listing of the Common Shares on the Toronto Stock Exchange or, if listed on a U.S. national securities exchange, the NYSE, the AMEX, the Nasdaq National Market or the Nasdaq
SmallCap Market, on such exchange or market, (ii) cause all the Registrable Securities covered by a Registration Statement to be listed (or quoted, as applicable) on each United States or Canadian securities exchange or trading market on which
securities of the same class or series issued by the Company are then listed or traded, and (iii) without limiting the generality of the foregoing, to arrange for at least three market makers to register with the National Association of
Securities Dealers, Inc. (“NASD”) as such with respect to such Registrable Securities. The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 4(k). 
  
 l. The Company shall cooperate with each Investor who holds Registrable
Securities being offered and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement
and enable such certificates to be in such denominations or amounts, as the case may be, as the Investors may reasonably request and registered in such names as the Investors may request. 
  
 m. The Company shall provide a transfer agent and registrar of all such Registrable Securities not later than the effective
date of the applicable Registration Statement. 
  
 n. If requested
by an Investor, the Company shall (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as an Investor requests to be included therein relating to the sale and distribution of Registrable
Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering;
(ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as
soon as practicable, supplement or make amendments to any Registration Statement if reasonably requested by an Investor of such Registrable Securities. 
  
 o. The Company shall use its reasonable efforts to cause the Registrable Securities covered by the applicable Registration Statement to be registered with
or approved by such other governmental agencies or 

  

 -7- 

 
authorities in the United States and Canada as may be necessary to consummate the disposition of such Registrable Securities. 
  
 p. The Company shall make generally available to its security holders, as
soon as practicable, an earnings statement (in form complying with the provisions of Rule 158 under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company’s fiscal quarter next following the effective
date of a Registration Statement. 
  
 q. The Company shall
otherwise use its reasonable efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder. 
  
 r. Within two (2) Business Days after a Registration Statement that covers applicable Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to each Investor whose Registrable Securities are included in such Registration Statement)
confirmation that such Registration Statement has been declared effective by the SEC, provided that if the Company changes its transfer agent, it shall immediately deliver any previously delivered notices under this Section 4(r) and any
subsequent notices to such new transfer agent. 
  
 s. The Company
shall make such filings with the NASD (including providing all required information and paying required fees related thereto) as and when requested by an Investor and make all other filings and take all other actions reasonably necessary to expedite
and facilitate disposition by Investors of Registrable Securities pursuant to a Registration Statement. 
  
 t. Notwithstanding anything to the contrary in Section 4(f), at any time after the applicable Registration Statement has been declared effective by
the SEC, the Company may delay the disclosure of material non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best
interest of the Company and, in the opinion of counsel to the Company, otherwise required (a “Post-Effectiveness Grace Period,” and along with each Effectiveness Request Grace Period and Current Report Update Grace Period, each a
“Grace Period”); provided that the Company shall promptly (i) notify the Investor in writing of the existence of material non-public information giving rise to a Post-Effectiveness Grace Period (provided that in each notice the
Company shall not disclose the content of such material nonpublic information to the Investor) and the date on which the Post-Effectiveness Grace Period will begin, and (ii) notify the Investor in writing of the date on which the
Post-Effectiveness Grace Period ends. Notwithstanding anything to the contrary contained herein, no Grace Period shall exceed 30 consecutive days, any Grace Periods during any 365-day period shall not exceed an aggregate of 60 days, and the first
day of any Grace Period must be at least two (2) Trading Days after the last day of any prior Grace Period (a Grace Period that satisfies all of the requirements of Sections 4(a) and 4(b) and this Section 4(t), as applicable, being
referred to as an “Allowable Grace Period”). For purposes of determining the length of a Post-Effectiveness Grace Period under this Section 4(t), the Post-Effectiveness Grace Period shall begin on and include the date the
holders receive the notice referred to in clause (i) and shall end on and include the later of the date the holders receive the notice referred to in clause (ii) and the date referred to in such notice. The provisions of Section 4(f)
hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of a Post-Effectiveness Grace Period, the Company shall again be bound by the first sentence of Section 4(f) with respect to the information giving
rise thereto unless such material non-public information is no longer applicable. 
  
 u. After the date of this Agreement, the Company shall not, without the prior written consent of Investors holding a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or
prospective holder of any securities of the Company that would grant such holder registration rights senior to those granted to the Investor hereunder. 
  

	5.	OBLIGATIONS OF THE INVESTORS. 

  
 a. At least six (6) Business Days prior to the first anticipated filing date of a Registration Statement filed pursuant to Sections 2 or 3 hereof and
at least five (5) Business Days prior to the filing of any amendment or supplement to a Registration Statement, the Company shall notify each Investor in writing of the information, if 

  

 -8- 

 
any, the Company requires from each such Investor if such Investor elects to have any of such Investor’s Registrable Securities included in such
Registration Statement or, with respect to an amendment or a supplement, if such Investor’s Registrable Securities are included in such Registration Statement (each an “Information Request”). Provided that the Company shall
have complied with its obligations set forth in the preceding sentence, it shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a
particular Investor that such Investor shall furnish to the Company, in response to an Information Request, such information regarding itself; the Registrable Securities held by it and the intended method of disposition of the Registrable Securities
held by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. 
  
 b. Each Investor, by such Investor’s acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such
Investor’s election to exclude all of such Investor’s Registrable Securities from such Registration Statement. 
  
 c. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4(g) or the
first sentence of Section 4(f) or written notice from the Company of a Grace Period, such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities
until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 4(f) or receipt of notice that no supplement or amendment is required or that the Grace Period has ended. Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to deliver unlegended Common Shares to a transferee of an Investor in connection with any sale of Registrable Securities pursuant to a Registration Statement covering such
Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor’s receipt of a notice from the Company of the happening of any event of the kind described in Section 4(g) or the first
sentence of Section 4(f) and for which the Investor has not yet settled. 
  

	6.	EXPENSES OF REGISTRATION. 

  
 All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant
to Sections 2, 3 and 4, including all registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company shall be paid by the Company, except as provided in Section 4(h). The
Company shall also reimburse the Investor for the reasonable fees and disbursements of Legal Counsel in connection with registration, filing or qualification pursuant to Sections 2, 3 and 4 of this Agreement, up to a maximum of $10,000 per
Registration Statement. 
  

	7.	INDEMNIFICATION. 

  
 In the event any Registrable Securities are included in a Registration Statement under this Agreement: 
  
 a. To the fullest extent permitted by law, the Company will, and hereby does,
indemnify, hold harmless and defend each Investor, the directors, officers, partners, employees, agents, representatives of, and each Person, if any, who controls any Investor within the meaning of the 1933 Act, the 1934 Act or the Canadian
Securities Laws (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or
several (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative
or other regulatory agency or body (including the SEC or any state or provincial securities commission authority or self-regulatory organization, in the United States, Canada or anywhere else in the world), whether pending or threatened, whether or
not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out
of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under
the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to 

  

 -9- 

 
state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not
misleading, (iii) any violation or alleged violation by the Company of the 1933 Act, the 1934 Act, any of the Canadian Securities Laws, any other law, including any state, provincial or foreign securities law, or any rule or regulation
thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any material violation of this Agreement by the Company (the matters in the foregoing clauses (i) through (iv) being,
collectively, “Violations”). Subject to Section 7(c), the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(a): (i) shall not apply to a Claim by an
Indemnified Person arising out of or based upon a Violation that occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person for such Indemnified Person expressly for use in connection
with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 4(d); (ii) with respect to any preliminary prospectus,
shall not inure to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected in the prospectus, as then amended or supplemented, if such prospectus was timely made available by the Company pursuant to Section 4(d), and the Indemnified Person
was promptly advised in writing not to use the incorrect preliminary prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding such advice, used it; (iii) shall not be available to the extent such Claim
is based on a failure of the Investor to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 4(d); and (iv) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 10. 
  
 b. In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to
severally and not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 7(a), the Company, each of its directors, each of its officers who signs the Registration Statement, and each
Person, if any, who controls the Company within the meaning of the 1933 Act, the 1934 Act or the Canadian Securities Laws (each an “Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become
subject, under the 1933 Act, the 1934 Act, the Canadian Securities Laws or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only to the extent, that such Violation
occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 7(c), such Investor will reimburse, promptly
as such expenses are incurred and are due and payable, any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in
this Section 7(b) and the agreement with respect to contribution contained in Section 8 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which
consent shall not be unreasonably withheld; provided, further, however, that the aggregate liability of the Investor in connection with any Violation shall not exceed the net proceeds to such Investor as a result of the sale of Registrable
Securities pursuant to the Registration Statement giving rise to such Claim. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the
Registrable Securities by the Investor pursuant to Section 10. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(b) with respect to any preliminary prospectus shall not
inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented. 
  

 -10- 

 c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 7 of
notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying
party under this Section 7, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be. In any such
proceeding, any Indemnified Person or Indemnified Party may retain its own counsel, but, except as provided in the following sentence, the fees and expenses of that counsel will be at the expense of that Indemnified Person or Indemnified Party, as
the case may be, unless (i) the indemnifying party and the Indemnified Person or Indemnified Party, as applicable, shall have mutually agreed to the retention of that counsel, (ii) the indemnifying party does not assume the defense of such
proceeding in a timely manner or (iii) in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel for the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate
due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding, in which case the Company shall pay reasonable fees for up to one separate legal
counsel for the Investors, and such legal counsel shall be selected by the Investor(s) holding at least two-thirds (2/3) in interest of the Registrable Securities included in the Registration Statement to which the Claim relates. The
Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information
reasonably available to the Indemnified Party or Indemnified Person which relates to such action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or
any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not
unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise
with respect to any pending or threatened action or claim in respect of which indemnification or contribution may be or has been sought hereunder (whether or not the Indemnified Party or Indemnified Person is an actual or potential party to such
action or claim), which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such Claim or litigation. Following
indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which
indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or
Indemnified Party under this Section 7, except to the extent that the indemnifying party is prejudiced in its ability to defend such action. 
  
 d. The indemnification required by this Section 7 shall be made by periodic payments of the amount thereof during the course of the investigation or
defense, as and when bills are received or Indemnified Damages are incurred. 
  
 e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and
(ii) any liabilities the indemnifying party may be subject to pursuant to the law. 
  

	8.	CONTRIBUTION. 

  
 To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section 7 to the fullest extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) in connection with such sale, shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited to an amount equal to the net amount of proceeds received by such seller from the sale of such Registrable Securities pursuant to the Registration
Statement 

  

 -11- 

 
giving rise to such action or claim for indemnification less the amount of any damages that such seller has otherwise been required to pay in connection with
such sale. 
  

	9.	REPORTS UNDER THE 1934 ACT. 

  
 With a view to making available to the Investor the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC
that may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule 144”), after the Company first becomes subject to reporting obligations under the 1934 Act, the Company agrees to:

  
 a. make and keep public information available, as those terms
are understood and defined in Rule 144; 
  
 b. file with the SEC

similar or successor reports required of the Company under the 1934 Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

  
 c. furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon written request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without
registration. 
  

	10.	ASSIGNMENT OF REGISTRATION RIGHTS. 

  
 The rights under this Agreement shall be automatically assignable by the Purchaser to any transferee or assignee of all or any portion of Registrable
Securities if: (i) the Purchaser agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within five (5) Business Days after such transfer or assignment;
(ii) the Company is, within five (5) Business Days after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such
registration rights are being transferred or assigned; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act or any applicable state
securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained
herein; and (v) in the case of a transfer or assignment of fewer than all of the Registrable Securities then held by the Investor to a Person that is not an affiliate of the Investor, at least 9,000,000 Registrable Securities (subject to
adjustment for stock splits, stock dividends, stock combinations and similar transactions after the date of this Agreement) are transferred or assigned to the transferee or assignee. 
  

	11.	AMENDMENT OF REGISTRATION RIGHTS. 

  
 Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company and Investors who then hold at least two-thirds (2/3) of the Registrable Securities. Any amendment or waiver effected in accordance with this Section 11 shall be
binding upon each Investor and the Company. No such amendment shall be effective to the extent that it applies to less than all of the holders of the Registrable Securities. No consideration shall be offered or paid to any Person to amend or consent
to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to all of the parties to this Agreement.

 REGISTRATION RIGHTS AGREEMENT 
  

REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of November 4, 2005, by and between Gastar Exploration
Ltd., an Alberta, Canada corporation (the “Company”), and Chesapeake Energy Corporation, an Oklahoma corporation (the “Purchaser”). 
  
 WHEREAS: 
  
 In connection with the Common Share Purchase Agreement dated November 4, 2005 by and between the parties hereto (the “Purchase

 Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in the Purchase Agreement. 
  

	2.	DEMAND REGISTRATION. 

  
 a. Request for Registration. At any time after the earlier of January 1, 2006 or the date of effectiveness of the Company’s registration
statement on Form S-1 (File No. 333-127498) (the “Existing Registration Statement”), if the Company shall receive a written request (“Demand Notice”) from an Investor holding at least 30% of the Registrable
Securities then outstanding (the “Initiating Investor”) for registration under the 1933 Act (a “Demand Registration”) of all or part of its Registrable Securities but not less than 30% of the Registrable Securities
then outstanding, then the Company shall, within 15 days of the receipt thereof, give written notice of such Demand Notice to each Investor. Within 15 days after receiving such notice, each Investor may make a written request to the Company that any
or all of the Investor’s Registrable Securities be included in the Demand Registration, which notice shall specify the number of shares to be so included. Subject to Section 2(e) hereof, the Company shall include in the Demand Registration
(or in a separate Registration Statement filed concurrently therewith) all Registrable Securities with respect to which the Company has received a written request for inclusion therein within 15 days after the receipt by such Investor of the
Company’s notice. Each Investor shall be permitted to withdraw all or part of the Investor’s Registrable Securities requested to be included in the Demand Registration at any time prior to the effective date of such Demand Registration
without any liability for any registration expenses. The Demand Notice will specify the number of shares of Registrable Securities proposed to be sold and will also specify the intended method of disposition thereof and the jurisdictions in which
registration is reasonably desired. 
  
 b. Limitation on Demand
Registration. The Company shall not be obligated to effect more than three Demand Registrations under this Section 2. Notwithstanding any provision of this Agreement to the contrary, the Company shall be entitled to postpone (but not more
than once in any twelve month period), for a reasonable period of time not in excess of 90 days, the filing of a Registration Statement if the Company delivers to the Investors a certificate signed by the Chief Executive Officer or Chief Financial
Officer of the Company certifying that, in the good faith judgment of the Board of Directors of the Company, such registration and offering would reasonably be expected to materially adversely affect or materially interfere with any bona fide
material financing of the Company or any material transaction under consideration by the Company or would require disclosure of information that has not been disclosed to the public, the premature disclosure of which would materially adversely
affect the Company. Such certificate shall contain a statement of the reasons for such postponement and an approximation of the anticipated delay. The Persons receiving such certificate shall keep the information contained in such certificate
confidential subject to the same terms set forth in Section 4(i). If the Company shall so postpone the filing of a Registration Statement, the Initiating Investor shall have the right to withdraw the request for registration by giving written
notice to the Company within 10 days of the anticipated 

  

 -2- 

 
termination date of the postponement period, as provided in the certificate delivered by the Company pursuant hereto, and in the event of such withdrawal,
such request shall not be counted for purposes of the number of Demand Registrations to which the Investors are entitled pursuant to the terms of this Agreement. 
  
 c. Effective Registration. A registration will not count as a Demand Registration (i) unless a Registration
Statement with respect thereto has become effective (unless the Initiating Investor withdraws its shares of Registrable Securities requested to be included in the Demand Registration), (ii) if after it has become effective, such registration is
interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason not attributable to an Investor and has not thereafter become effective, or (iii) if the conditions to
closing specified in the underwriting agreement, if any, entered into in connection with such registration are not satisfied or waived, other than by reason of a failure on the part of an Investor. 
  
 d. No Third-Party Piggy-Back on Demand Registrations without Consent.
Neither the Company nor any of its security holders who are not Investors may include securities of the Company in any Demand Registration without the prior written consent of the Initiating Investor. 
  
 e. Priority on Demand Registrations. In the event an offering pursuant
to a Demand Registration shall be in the form of an underwritten offering pursuant to subsection (f) below, if the managing underwriter or underwriters of such offering advise the Company and the Investors in writing that, in their good faith
judgment, the number of Registrable Securities and any other securities requested to be included in such offering is sufficiently large to adversely affect the success of such offering (a “Material Adverse Effect”), then
(i) the amount of securities to be included in the Demand Registration for any Persons (other than the Company and the Investors) shall first be reduced, thereafter the securities to be offered for the account of the Company shall be reduced,
and thereafter the Registrable Securities to be offered for the account of the Investors shall be reduced so that the total number of securities to be included in the offering shall be the recommended number by such managing underwriter or
underwriters, unless the Investors desire to sell a number of Registrable Securities that is less than the total amount that they are entitled to sell, in which event the number of Registrable Securities not so elected to be sold shall be allocated
first to the Company and then to any other holders of securities of the Company permitted to include their securities in such Demand Registration pursuant to Section 2(d). 
  
 f. Manner of Offering; Selection of Underwriters. If the Initiating Investor so requests, the offering of Registrable
Securities pursuant to a Demand Registration shall be in the form of an underwritten offering and all Persons electing to participate in such Demand Registration shall be bound by such determination. If a Demand Registration is in the form of an
underwritten offering, the Initiating Investor shall select the managing underwriter or underwriters to be used in connection with the offering; provided, however, that such underwriter or underwriters must be reasonably satisfactory
to the Company. 
  

	3.	PIGGY-BACK REGISTRATION. 

  
 a. Request for Registration. At any time after the date hereof, if the Company proposes to file a registration statement under the 1933 Act (other
than (i) a registration statement on Form S-4 or S-8 or any successor form that may be adopted by the SEC, (ii) a registration statement filed in connection with an exchange offer or offering of securities or debt solely to the
Company’s existing security or debt holders, (iii) a registration statement filed as a “shelf” registration pursuant to Rule 415 under the 1933 Act or (iv) the Existing Registration Statement (an “Exempt
Offering”)) with respect to an offering of securities of the same class as the Registrable Securities for the Company’s own account or for the account of any of its security holders, then the Company shall give written notice of such
proposed filing to each Investor as soon as practicable (but in no event less than 20 nor more than 60 days before the anticipated filing date). Such notice shall offer each Investor the opportunity to have all or any of the Registrable Securities
held by such Investor included in the Registration Statement proposed to be filed or, at the Company’s option, in a separate Registration Statement to be filed concurrently with such Registration Statement (the “Piggy-Back
Registration”). Within 15 days after receiving such notice, each Investor may make a written request to the Company that any or all of the Investor’s Registrable Securities be included in the Piggy-Back Registration, which notice shall
specify the number of shares to be so included. Subject to Section 3(b) hereof, the Company shall include in the Piggy-Back Registration (or in a separate Registration Statement filed concurrently therewith) all Registrable Securities with
respect to which the Company has received 

  

 -3- 

 
a written request for inclusion therein within 15 days after the receipt by such Investor of the Company’s notice. The Company may in its discretion
withdraw any Registration Statement filed pursuant to this Section 3(a) subsequent to its filing without liability to any Investor except with respect to expenses. Each Investor shall be permitted to withdraw all or part of the Investor’s
Registrable Securities requested to be included in a Piggy-Back Registration at any time prior to the effective date of such Piggy-Back Registration without any liability for any registration expenses. 
  
 b. Priority on Piggy-Back Registration. If any Piggy-Back Registration
is to be an underwritten offering, the Company shall use its reasonable efforts to cause the managing underwriter or underwriters to permit the shares of Registrable Securities requested by each Investor to be included in the Piggy-Back Registration
(on the same terms and conditions as similar securities of the Company included therein to the extent appropriate). Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering advise the Company in writing that, in
their good faith judgment, the number of Registrable Securities and any other securities requested to be included in such offering is sufficiently large to have a Material Adverse Effect, then (i) if such Piggy-Back Registration is incident to
a primary registration on behalf of the Company, the amount of securities to be included in the Piggy-Back Registration for any Persons (other than the Company) shall be reduced pro rata so that the total number of securities to be included in the
offering shall be the recommended number by such managing underwriter or underwriters, unless an Investor desires to sell a number of Registrable Securities that is less than the total amount that it is entitled to sell, and (ii) if such
Piggy-Back Registration is incident to a secondary registration on behalf of holders of securities of the Company, the Company shall include in such Registration Statement (A) first, the number of securities of such Person(s) on whose behalf
the registration is being made, (B) second, the number of Registrable Securities requested to be included in such registration pursuant to this Section 3 and for the account of all other Persons pursuant to similar piggy-back registration
rights in excess of the securities such Persons on whose behalf the registration is being made propose to sell that, in the good faith judgment of such managing underwriters, can be sold without causing a Material Adverse Effect on such offering,
and (C) third, the number of securities requested to be included in such registration by the Company. 
  
 c. Legal Counsel. Subject to Section 6 hereof, the Purchaser shall have the right to select one legal counsel to review, on behalf of the
Purchaser, any registration pursuant to this Agreement (“Legal Counsel”), which shall be Commercial Law Group, P.C., or such other counsel as thereafter designated in writing to the Company by the Purchaser or its assignee. The
Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations under this Agreement. 
  

	4.	REGISTRATION PROCEDURES. 

  
 At such time as the Company is obligated to effect the registration of the Registrable Securities with the SEC pursuant to Section 2 or 3 hereof, the
Company will use its reasonable efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations: 
  
 a. The Company shall promptly prepare and file with the SEC a Registration
Statement with respect to the applicable Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective as soon as practicable after such filing. The Company shall keep each Registration Statement
effective at all times for a period of at least 120 days after the effective date thereof or such shorter period in which all Registrable Securities included in such Registration Statement have been sold (the “Registration Period”).
Such Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary
to make the statements therein, in light of the circumstances in which they were made, not misleading. The term “reasonable efforts” shall mean, among other things, that the Company shall submit to the SEC, within three (3) Business
Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further comments on the Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request; provided, however, that, subject to Section 4(t), the Company may delay (an “Effectiveness Request Grace
Period”) such submission of a request for 

  

 -4- 

 
acceleration of effectiveness of such Registration Statement if, in the good faith opinion of the Company and its counsel, such Effectiveness Request Grace
Period is necessary to avoid disclosure of material non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best interest of
the Company and, in the opinion of counsel to the Company, otherwise required; provided that the Company shall (i) promptly notify the Investor in writing of the existence of material non-public information giving rise to such an Effectiveness
Request Grace Period (provided that in each notice the Company shall not disclose the content of such material non-public information to the Investor), (ii) submit such request for acceleration of effectiveness as soon as, in the good faith
opinion of Company and its counsel, such Effectiveness Request Grace Period is no longer necessary (subject to Section 4(t)), and (iii) notify the Investor in writing of the date on which the Effectiveness Request Grace Period ends.

  
 b. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) to each Registration Statement as may be necessary to keep such Registration Statement effective at all times during the Registration Period, with respect to the disposition of all securities covered
by the Registration Statement and cause the related Prospectus to be supplemented by any Prospectus supplement as may be necessary to comply with the provisions of the 1933 Act with respect to the disposition of the securities of the Company covered
by such Registration Statement until such time as all of such securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement and as so
supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the 1933 Act. In the case of amendments and supplements to a Registration Statement that are required to be filed pursuant to this Agreement (including
pursuant to this Section 4(b)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended (the “1934 Act”), the Company shall have
incorporated such report by reference into the Registration Statement, if applicable and permitted by law, or shall file such amendments or supplements with the SEC as soon as practicable after such filing of the report; provided,
however, that the Company may delay the filing of any applicable supplement or amendment pursuant to Section 4(t) (any such delay, a “Current Report Update Grace Period”). 
  
 c. The Company shall (A) permit Legal Counsel to review and comment upon
(i) the Registration Statement at least five (5) Business Days prior to its filing with the SEC, and (ii) all amendments and supplements to the Registration Statement (except for Annual Reports on Form 10-K, Quarterly Reports on Form
l0-Q and Current Reports on Form 8-K and any similar or successor reports) within a reasonable number of days prior to their filing with the SEC, and (B) not file any document, Registration Statement, amendment or supplement described in the
foregoing clause (A) in a form to which Legal Counsel reasonably objects. The Company shall not submit a request for acceleration of the effectiveness of the Registration Statement or any amendment or supplement thereto without providing prior
notice thereof to Legal Counsel and each Investor. The Company shall furnish to Legal Counsel, without charge, (i) promptly after the same is prepared and filed with the SEC, one copy of the Registration Statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein by reference that have not been filed, or are not immediately available electronically, via EDGAR, and all exhibits, and (ii) upon the effectiveness of any
Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto. The Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations pursuant to
this Section 4. 
  
 d. The Company shall furnish to each
Investor whose Registrable Securities are included in a Registration Statement, and to any managing underwriter or underwriters, without charge, at least one conformed copy of the Registration Statement, the Prospectus and Prospectus
supplements, if applicable, and each post-effective amendment thereto, including financial statements (but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits, unless requested in
writing by the Investor or the managing underwriter or underwriters) and deliver to the Investor, without charge, as many copies of the Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as the
Investor may reasonably request in connection with the distribution of the Registrable Securities. 
  

 -5- 

 e. The Company shall use its reasonable efforts to (i) register and qualify, unless an exemption
from registration and qualification applies, the resale by the Investor of the Registrable Securities covered by a Registration Statement under the securities or “blue sky” laws of all the states of the United States, (ii) prepare and
file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable
Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to
qualify but for this Section 4(e) or (y) subject itself to general taxation in any such jurisdiction. The Company shall promptly notify Legal Counsel and each Investor who holds Registrable Securities of the receipt by the Company of any
notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice
of the initiation or threatening of any proceeding for such purpose. 
  
 f. The Company shall notify Legal Counsel and each Investor in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement,
as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not
misleading (provided that in no event shall such notice contain any material, nonpublic information), and promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver to each
Investor, without charge, as many copies of the Prospectus included in such Registration Statement and each amendment or supplement thereto as such Investor may reasonably request in connection with the distribution of the Registrable Securities.
The Company shall also promptly notify Legal Counsel and each Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment
has become effective (notification of such effectiveness shall be delivered electronically to Legal Counsel and each Investor on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for amendments or
supplements to a Registration Statement or related prospectus or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate. 
  
 g. The Company shall use its reasonable efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the
withdrawal of such order or suspension as soon as practicable and to notify Legal Counsel and each Investor who holds Registrable Securities being sold of the issuance of such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose. 
  
 h. At
the reasonable request (in the context of the securities laws) of any Investor, the Company shall furnish to such Investor, on the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as an Investor
may reasonably request (i) a letter, dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the Investor, and (ii) an opinion, dated as of such date, of counsel representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten
public offering, addressed to the Investor, provided that such Investor shall reimburse the Company for its out-of-pocket expenses incurred in connection with the furnishing of any such letter and opinion. 
  
 i. At the reasonable request (in the context of the securities laws) of any
Investor, the Company shall upon receipt of a waiver of such investor’s non-public information requirements make available for inspection during regular business hours by (i) any Investor, (ii) Legal Counsel and (iii) one firm of
accountants or other agents retained by the Investors (collectively, the “Inspectors”), all pertinent financial and other records, and pertinent corporate documents and properties of the Company (collectively, the
“Records”), as shall be reasonably 

  

 -6- 

 
deemed necessary by each Inspector, and cause the Company’s officers, directors and employees to supply all information that any Inspector may
reasonably request; provided, however, that each Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to an Investor and Legal Counsel) or use of any Record or other information that the Company determines in
good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise
required under the 1933 Act, (b) the release of such Records is ordered pursuant to a final, non-appealable subpoena or order from a court or government body of competent jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in violation of this or any other agreement of which the Inspector has knowledge. Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court
or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the
Records deemed confidential. Each Inspector that exercises its rights under this Section 4(i) shall be obligated to execute a non-disclosure agreement containing such reasonable terms as the Company may request. The fees and expenses of the
Inspectors shall be borne by the applicable Investor or Investors. 
  
 j. The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state securities laws,
(ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order
from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees that it
shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Investor and allow such Investor, at
the Investor’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information. 
  
 k. The Company shall use its reasonable efforts to (i) maintain the listing of the Common Shares on the Toronto Stock Exchange or, if listed on a
U.S. national securities exchange, the NYSE, the AMEX, the Nasdaq National Market or the Nasdaq SmallCap Market, on such exchange or market, (ii) cause all the Registrable Securities covered by a Registration Statement to be listed (or quoted,
as applicable) on each United States or Canadian securities exchange or trading market on which securities of the same class or series issued by the Company are then listed or traded, and (iii) without limiting the generality of the foregoing,
to arrange for at least three market makers to register with the National Association of Securities Dealers, Inc. (“NASD”) as such with respect to such Registrable Securities. The Company shall pay all fees and expenses in
connection with satisfying its obligation under this Section 4(k). 
  
 l. The Company shall cooperate with each Investor who holds Registrable Securities being offered and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing
the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the Investors may reasonably request and registered in such names as the
Investors may request. 
  
 m. The Company shall provide a transfer
agent and registrar of all such Registrable Securities not later than the effective date of the applicable Registration Statement. 
  
 n. If requested by an Investor, the Company shall (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such
information as an Investor requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being
paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of
the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, 

  

 -7- 

 
supplement or make amendments to any Registration Statement if reasonably requested by an Investor of such Registrable Securities. 
  
 o. The Company shall use its reasonable efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered with or approved by such other governmental agencies or authorities in the United States and Canada as may be necessary to consummate the disposition of such Registrable
Securities. 
  
 p. The Company shall make generally available to
its security holders, as soon as practicable, an earnings statement (in form complying with the provisions of Rule 158 under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company’s fiscal quarter
next following the effective date of a Registration Statement. 
  
 q. The Company shall otherwise use its reasonable efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder. 
  
 r. Within two (2) Business Days after a Registration Statement that covers applicable Registrable Securities is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to each Investor whose Registrable Securities are included in such
Registration Statement) confirmation that such Registration Statement has been declared effective by the SEC, provided that if the Company changes its transfer agent, it shall immediately deliver any previously delivered notices under this
Section 4(r) and any subsequent notices to such new transfer agent. 
  
 s. The Company shall make such filings with the NASD (including providing all required information and paying required fees related thereto) as and when requested by an Investor and make all other filings and take all
other actions reasonably necessary to expedite and facilitate disposition by Investors of Registrable Securities pursuant to a Registration Statement. 
  
 t. Notwithstanding anything to the contrary in Section 4(f), at any time after the applicable Registration Statement has been declared effective by
the SEC, the Company may delay the disclosure of material non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best
interest of the Company and, in the opinion of counsel to the Company, otherwise required (a “Post-Effectiveness Grace Period,” and along with each Effectiveness Request Grace Period and Current Report Update Grace Period, each a
“Grace Period”); provided that the Company shall promptly (i) notify the Investor in writing of the existence of material non-public information giving rise to a Post-Effectiveness Grace Period (provided that in each notice the
Company shall not disclose the content of such material nonpublic information to the Investor) and the date on which the Post-Effectiveness Grace Period will begin, and (ii) notify the Investor in writing of the date on which the
Post-Effectiveness Grace Period ends. Notwithstanding anything to the contrary contained herein, no Grace Period shall exceed 30 consecutive days, any Grace Periods during any 365-day period shall not exceed an aggregate of 60 days, and the first
day of any Grace Period must be at least two (2) Trading Days after the last day of any prior Grace Period (a Grace Period that satisfies all of the requirements of Sections 4(a) and 4(b) and this Section 4(t), as applicable, being
referred to as an “Allowable Grace Period”). For purposes of determining the length of a Post-Effectiveness Grace Period under this Section 4(t), the Post-Effectiveness Grace Period shall begin on and include the date the
holders receive the notice referred to in clause (i) and shall end on and include the later of the date the holders receive the notice referred to in clause (ii) and the date referred to in such notice. The provisions of Section 4(f)
hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of a Post-Effectiveness Grace Period, the Company shall again be bound by the first sentence of Section 4(f) with respect to the information giving
rise thereto unless such material non-public information is no longer applicable. 
  
 u. After the date of this Agreement, the Company shall not, without the prior written consent of Investors holding a majority of the Registrable Securities then outstanding, enter into any agreement with any 

  

 -8- 

 
holder or prospective holder of any securities of the Company that would grant such holder registration rights senior to those granted to the Investor
hereunder. 
  

	5.	OBLIGATIONS OF THE INVESTORS. 

  
 a. At least six (6) Business Days prior to the first anticipated filing date of a Registration Statement filed pursuant to Sections 2 or 3 hereof and
at least five (5) Business Days prior to the filing of any amendment or supplement to a Registration Statement, the Company shall notify each Investor in writing of the information, if any, the Company requires from each such Investor if such
Investor elects to have any of such Investor’s Registrable Securities included in such Registration Statement or, with respect to an amendment or a supplement, if such Investor’s Registrable Securities are included in such Registration
Statement (each an “Information Request”). Provided that the Company shall have complied with its obligations set forth in the preceding sentence, it shall be a condition precedent to the obligations of the Company to complete the
registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company, in response to an Information Request, such information regarding itself; the Registrable
Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. 
  
 b. Each
Investor, by such Investor’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless
such Investor has notified the Company in writing of such Investor’s election to exclude all of such Investor’s Registrable Securities from such Registration Statement. 
  
 c. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind
described in Section 4(g) or the first sentence of Section 4(f) or written notice from the Company of a Grace Period, such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration
Statement(s) covering such Registrable Securities until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 4(f) or receipt of notice that no supplement or amendment is required or that
the Grace Period has ended. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended Common Shares to a transferee of an Investor in connection with any sale of Registrable Securities pursuant to a
Registration Statement covering such Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor’s receipt of a notice from the Company of the happening of any event of the kind described
in Section 4(g) or the first sentence of Section 4(f) and for which the Investor has not yet settled. 
  

	6.	EXPENSES OF REGISTRATION. 

  
 All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant
to Sections 2, 3 and 4, including all registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company shall be paid by the Company, except as provided in Section 4(h). The
Company shall also reimburse the Investor for the reasonable fees and disbursements of Legal Counsel in connection with registration, filing or qualification pursuant to Sections 2, 3 and 4 of this Agreement, up to a maximum of $10,000 per
Registration Statement. 
  

	7.	INDEMNIFICATION. 

  
 In the event any Registrable Securities are included in a Registration Statement under this Agreement: 
  
 a. To the fullest extent permitted by law, the Company will, and hereby does,
indemnify, hold harmless and defend each Investor, the directors, officers, partners, employees, agents, representatives of, and each Person, if any, who controls any Investor within the meaning of the 1933 Act, the 1934 Act or the Canadian
Securities Laws (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or
several 

  

 -9- 

 
(collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or
appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency or body (including the SEC or any state or provincial securities commission authority or self-regulatory organization, in the United
States, Canada or anywhere else in the world), whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims
(or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the
omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the
omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii) any violation or alleged violation
by the Company of the 1933 Act, the 1934 Act, any of the Canadian Securities Laws, any other law, including any state, provincial or foreign securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable
Securities pursuant to a Registration Statement or (iv) any material violation of this Agreement by the Company (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”). Subject to
Section 7(c), the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon a
Violation that occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person for such Indemnified Person expressly for use in connection with the preparation of the Registration Statement
or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 4(d); (ii) with respect to any preliminary prospectus, shall not inure to the benefit of any such person
from whom the person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected in the prospectus, as then amended or supplemented, if such prospectus was timely made available by the Company pursuant to Section 4(d), and the Indemnified Person was promptly advised in writing not to use
the incorrect preliminary prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding such advice, used it; (iii) shall not be available to the extent such Claim is based on a failure of the Investor to
deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 4(d); and (iv) shall not apply to amounts paid in settlement of any Claim if
such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the
Indemnified Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 10. 
  
 b. In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and not jointly indemnify,
hold harmless and defend, to the same extent and in the same manner as is set forth in Section 7(a), the Company, each of its directors, each of its officers who signs the Registration Statement, and each Person, if any, who controls the
Company within the meaning of the 1933 Act, the 1934 Act or the Canadian Securities Laws (each an “Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the 1933 Act, the 1934
Act, the Canadian Securities Laws or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in
conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 7(c), such Investor will reimburse, promptly as such expenses are incurred
and are due and payable, any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 7(b) and
the agreement with respect to contribution contained in Section 8 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such 

  

 -10- 

 
Investor, which consent shall not be unreasonably withheld; provided, further, however, that the aggregate liability of the Investor in connection with any
Violation shall not exceed the net proceeds to such Investor as a result of the sale of Registrable Securities pursuant to the Registration Statement giving rise to such Claim. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 10. Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 7(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was
corrected on a timely basis in the prospectus, as then amended or supplemented. 
  
 c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 7 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a
Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 7, deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually
satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be. In any such proceeding, any Indemnified Person or Indemnified Party may retain its own counsel, but, except as provided in the following
sentence, the fees and expenses of that counsel will be at the expense of that Indemnified Person or Indemnified Party, as the case may be, unless (i) the indemnifying party and the Indemnified Person or Indemnified Party, as applicable, shall
have mutually agreed to the retention of that counsel, (ii) the indemnifying party does not assume the defense of such proceeding in a timely manner or (iii) in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel for the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party
represented by such counsel in such proceeding, in which case the Company shall pay reasonable fees for up to one separate legal counsel for the Investors, and such legal counsel shall be selected by the Investor(s) holding at least two-thirds
(2/3) in interest of the Registrable Securities included in the Registration Statement to which the Claim relates. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation
or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or Claim. The indemnifying
party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action,
claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the
Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise with respect to any pending or threatened action or claim in respect of which indemnification or contribution may be or has
been sought hereunder (whether or not the Indemnified Party or Indemnified Person is an actual or potential party to such action or claim), which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party or Indemnified Person of a release from all liability in respect to such Claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or
Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement
of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 7, except to the extent that the indemnifying party is prejudiced in its ability to defend such
action. 
  
 d. The indemnification required by this Section 7
shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred. 
  
 e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the
Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law. 
  

 -11- 

	8.	CONTRIBUTION. 

  
 To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section 7 to the fullest extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) in connection with such sale, shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited to an amount equal to the net amount of proceeds received by such seller from the sale of such Registrable Securities pursuant to the Registration
Statement giving rise to such action or claim for indemnification less the amount of any damages that such seller has otherwise been required to pay in connection with such sale. 
  

	9.	REPORTS UNDER THE 1934 ACT. 

  
 With a view to making available to the Investor the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC
that may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule 144”), after the Company first becomes subject to reporting obligations under the 1934 Act, the Company agrees to:

  
 a. make and keep public information available, as those terms
are understood and defined in Rule 144; 
  
 b. file with the SEC
all Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on 8-K (other than Current Reports on Form 8-K that are required solely pursuant to Item 1.01, 1.02, 2.03, 2.04, 2.05, 2.06 or 4.02(a) of Form 8-K) and any
similar or successor reports required of the Company under the 1934 Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

  
 c. furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon written request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without
registration. 
  

	10.	ASSIGNMENT OF REGISTRATION RIGHTS. 

  
 The rights under this Agreement shall be automatically assignable by the Purchaser to any transferee or assignee of all or any portion of Registrable
Securities if: (i) the Purchaser agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within five (5) Business Days after such transfer or assignment;
(ii) the Company is, within five (5) Business Days after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such
registration rights are being transferred or assigned; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act or any applicable state
securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained
herein; and (v) in the case of a transfer or assignment of fewer than all of the Registrable Securities then held by the Investor to a Person that is not an affiliate of the Investor, at least 9,000,000 Registrable Securities (subject to
adjustment for stock splits, stock dividends, stock combinations and similar transactions after the date of this Agreement) are transferred or assigned to the transferee or assignee. 
  

 -12- 

	11.	AMENDMENT OF REGISTRATION RIGHTS. 

  
 Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company and Investors who then hold at least two-thirds (2/3) of the Registrable Securities. Any amendment or waiver effected in accordance with this Section 11 shall be
