	2.10	 U.S. Tax Matters 

For United States federal income tax purposes, the Parties intend to adopt this Agreement as a plan of reorganization. Under
all transactions contemplated by this Agreement, the Parties shall use commercially reasonable efforts to use solely Consideration Shares for the Exeter Shares acquired. Each Party shall use its commercially reasonable efforts to cause the
transactions contemplated by this Agreement to qualify as a “reorganization” within the meaning of Section 368(a)(1) of the Code and will use commercially reasonable efforts to avoid taking any action that would cause the transactions
not to qualify as a reorganization in accordance with Section 368(a)(1) of the Code. Each of the Parties shall report the transactions contemplated by this Agreement as a “reorganization” within the meaning of Section 368(a) of
the Code (to the extent that the transactions are reportable as such under the Code) and (to the extent that the transactions are reportable as such under the Code) shall not take any position that is contrary to such treatment, unless required
pursuant to a “determination” within the meaning of Section 1313(a) of the Code. Notwithstanding the foregoing, neither the Purchaser nor the Company makes any representation, warranty or covenant to any other Party or to any Exeter
Securityholder, any Exeter Shareholder or other holder of Exeter securities or Purchaser securities (including, without limitation, stock options, warrants, debt instruments or other similar rights or instruments) regarding the U.S. tax treatment of
the Offer, including, but not limited to, whether the exchange of Exeter Shares for Purchaser Shares will qualify as a reorganization within the meaning of Section 368(a) of the Code or as a tax-deferred
reorganization for purposes of any United States state or local income tax law. 
  

	2.11	 U.S. Securities Matters 

The Purchaser shall register the Consideration Shares on Form F-10 or such other
applicable form as required under the U.S. Securities Act to issue the Consideration Shares in the Offer. The Purchaser shall file a Schedule TO and any amendments thereto, and any other required documents pursuant to the applicable requirements of
the U.S. Exchange Act.

reasonable notice, to the Company’s and its subsidiaries’ businesses, properties, books and records and such other data and information as the Purchaser may reasonably request, as well as to its management personnel, subject however to
such access not interfering with the ordinary conduct of the businesses of the Company. Subject to compliance with applicable Laws and such requests not materially interfering with the ordinary conduct of the business of the Company, the Company

notwithstanding any other provision of this Agreement or any termination of this Agreement. If any provision of this Agreement otherwise conflicts or is inconsistent with any provision of the Confidentiality Agreement, the provisions of this
Agreement will supersede those of the Confidentiality Agreement but only to the extent of the conflict or inconsistency and all other provisions of the Confidentiality Agreement will remain in full force and effect.

Transaction”), the Company agrees to support the completion of such Alternative Transaction in the same manner as the Offer and shall otherwise fulfill its covenants contained in this Agreement in respect of such Alternative Transaction;
provided that the Purchaser shall extend the Outside Date by such number of days as is required to complete the Alternative Transaction. In particular but without limitation, and subject to this subsection 4.3(b), the Company agrees to holding a

	4.7	 Employment Agreements; Exeter Options 

(a) The Company shall cause, and it shall cause any of its subsidiaries to cause, officers of the Company and its subsidiaries
to provide resignations or shall terminate such officers with effect as and from the Effective Time. The Purchaser agrees that the Company, its subsidiaries and any successor to the Company (including any Surviving Corporation) shall honour and
comply with the terms of all of the severance payment obligations of the Company or its subsidiaries under the existing employment, consulting, change of control and severance agreements of the Company or its subsidiaries that are fully and
completely disclosed in Section 4.7(a) of the Exeter Disclosure Letter. The Company will use commercially reasonable efforts to cause the parties receiving severance payments to execute full and final releases of the Company and its
subsidiaries from all liability and obligations including in respect of the change of control entitlements in favour of the Company and in form and substance satisfactory to the Purchaser, acting reasonably. 

  
 - 61 - 

 (b) No employee benefit, plan, contract or other arrangement provides for a gross
up by the Company or any of its subsidiaries for any taxes imposed under Sections 409A or 4999 of the Code. 
 (c) The
Company shall be exclusively responsible to make all payments contemplated in this Section 4.7 and shall deduct and withhold from any such payments such amounts as the Company is required to deduct and withhold with respect to such payment
under the Tax Act, the Code, and the rules and regulations promulgated thereunder, or any provision of any provincial, state, local or foreign tax Law as counsel may advise is required to be so deducted and withheld by the Company. 

(d) Subject to the terms of this Agreement and applicable Regulatory Approval, the Parties agree that: 

 

	 	(i)	 the consummation of the Offer/the announcement of the Offer, when issued by the Purchaser, will be a
“change of control” of Exeter for the purposes of the Stock Option Plan; 

  

	 	(ii)	 subject to the receipt of all necessary approvals of Regulatory Authorities, Exeter shall take all such steps
as may be necessary or desirable to amend the Stock Option Plan and Exeter Options to provide: (A) for the extension of the termination period; and (B) that each holder of vested Exeter Options shall be entitled, at his or her option (in addition to
not exercising), to (i) exercise such Exeter Options, in accordance with their terms, and thereby acquire Exeter Shares; (ii) effect a cashless exercise of their Exeter Options solely for purposes of tendering to the Offer all Exeter Shares issued
in connection with such cashless exercise, or (iii) in lieu of exercising Exeter Options, surrender or cancel such Exeter Options to Exeter in exchange for a payment by Exeter in the form of Exeter Shares having a fair market value equal to the
amount by which the Offer Consideration the Exeter Shares which could be acquired pursuant to the exercise of such Exeter Options exceeds the aggregate exercise price of such Exeter Options; 

 

	 	(iii)	 the parties agree that all Exeter Options tendered to Exeter for exercise, surrender or cancellation,
conditional upon the Purchaser taking up the Exeter Shares under the Offer (a “Conditional Option Exercise”), shall be deemed to have been exercised or surrendered immediately prior to the take up of the Exeter Shares by the
Purchaser. The Purchaser shall accept as validly tendered to the Offer all of the Exeter Shares to be issued pursuant to the Conditional Option Exercise, provided that the holders of such Exeter Options otherwise validly accept the Offer in
accordance with its terms with respect to such Exeter Shares and provided that such holders agree to surrender any of their remaining Exeter Options to Exeter for cancellation effective on the take-up date; 

 

	 	(iv)	 any Exeter Options outstanding following completion of the Offer shall be adjusted in accordance with the
terms of the Stock Option Plan upon the Purchaser becoming the sole shareholder of Exeter to be exercisable for the same aggregate consideration for Purchaser Shares on the basis of 0.12 of a Purchaser Share in lieu of each Exeter Share to which the
holder was therefore entitled upon exercise of such Exeter Option and the Exeter Options shall continue to be governed by and be subject to the terms of the Stock Option Plan and any applicable agreement thereunder; 

 

	 	(v)	 Exeter agrees that it will use commercially reasonable efforts to: (i) allow all outstanding Exeter Options to
be either exercised, terminated, surrendered, cancelled or expire prior to the Take-Up Date in accordance with Section 4.7(d)(B)(i), (ii) or (iii), provided that, except as provided in Section 4.7(d)(i) or (ii), Exeter shall not pay the holders any
amount in consideration therefor without the prior written approval of the Purchaser, and Exeter shall not grant any additional Exeter Options or other rights to purchase or acquire Exeter Shares, or make any amendments to outstanding Exeter Options
without the prior written consent of the Purchaser; 

  

	 	(vi)	 Exeter shall withhold and remit to the relevant Regulatory Authority any amounts required in connection with
the exercise, surrender or cancellation of the Exeter Options and Exeter may take all reasonable steps to ensure that such withholding and remittance is made; and 

 

	 	(vii)	 the Parties will take all such actions as are reasonably necessary to give effect to this subsection 4.7(d).

  

	4.8	 Indemnification and Insurance 

(a) The Parties agree that all rights to indemnification existing in favour of the present and former directors and officers of
the Company (each such present or former director or officer of the Company being herein referred to as an “Indemnified Party” and such persons collectively being referred to as the “Indemnified Parties”) as
provided by contracts or agreements to which the Company is a party and in effect as of the date hereof, that are fully and completely disclosed in the Exeter Disclosure Letter and copies of which are provided to the Purchaser prior to the date
hereof, and, as of the Effective Time, will survive and will continue in full force and effect and without modification, and the Company and any successor to the Company (including any Surviving Corporation) shall continue to honour such rights of
indemnification and indemnify the Indemnified Parties pursuant thereto, with respect to actions or omissions of the Indemnified Parties occurring prior to the Effective Time, for six years following the Effective Time. 

  
 - 62 - 

 (b) Prior to the Effective Time, notwithstanding any other provision hereof, the
Company may purchase prepaid non-cancellable run-off directors’ and officers’ liability insurance, at a cost not exceeding 200% of the Company’s current
annual aggregate premium for directors’ and officers’ liability policies currently maintained by the Company, providing coverage for a period of six years from the Effective Time with respect to claims arising from or related to facts or
events which occur on or prior to the Effective Time. 
 (c) The provisions of this Section 4.8 are intended for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and his or her legal representatives and, for such purpose, the Company hereby confirms that it is acting as trustee on their behalf, and agrees to enforce the
provisions of this Section 4.8 on their behalf. Furthermore, this Section 4.8 shall survive the termination of this Agreement as a result of the occurrence of the Effective Time for a period of six years. 

 

	4.9	 Reorganization 

(a) The Company shall effect such reorganization of its business, operations, subsidiaries and assets or such other
transactions (each, a “Pre-Acquisition Reorganization”) as the Purchaser may reasonably request prior to the Expiry Time; provided, however, that the Company need not effect a Pre-Acquisition Reorganization which would impede or materially delay the take-up of Exeter Shares and the consummation of the Contemplated Transactions or that would be
prejudicial to the Company, its subsidiaries or the Exeter Securityholders or that would involve a material amount of the time and attention of the Company’s officers or employees. 

(b) Without limiting the foregoing and other than as set forth in clause (a) above, the Company shall use its best efforts
to obtain all necessary consents, approvals or waivers from any persons to effect each Pre-Acquisition Reorganization, and the Company shall cooperate with the Purchaser in structuring, planning and
implementing any such Pre-Acquisition Reorganization. The Purchaser shall provide written notice to the Company of any proposed Pre-Acquisition Reorganization at least
ten Business Days prior to the Expiry Time. In addition: 
  

	 	(i)	 any Pre-Acquisition Reorganization shall not unreasonably interfere
with the Company’s material operations prior to the Effective Time and shall not become effective until the Purchaser shall have waived or confirmed in writing the satisfaction of all conditions in its favour in the Offer and in this Agreement
and shall have confirmed in writing that it is prepared to promptly, and without condition, proceed to effect the acquisition of the Exeter Shares; 

  

	 	(ii)	 any Pre-Acquisition Reorganization shall not require the Company to
contravene any applicable Laws, its organizational documents or any Material Contract; and 

  
 - 63 - 

	 	(iii)	 the Company shall not be obligated to take any action that could result in any Taxes being imposed on, or any
adverse Tax or other consequences to, any Exeter Securityholder incrementally greater than the Taxes or other consequences to such party in connection with the take-up of Exeter Shares and the consummation of
the Offer in the absence of any Pre-Acquisition Reorganization. 

(c) The Purchaser acknowledges and agrees that the planning for and implementation of any
Pre-Acquisition Reorganization shall not be considered a breach of any covenant under this Agreement and shall not be considered in determining whether a representation or warranty of the Company hereunder has
been breached. The Purchaser and the Company shall work cooperatively and use commercially reasonable efforts to prepare prior to the Expiry Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization. For greater certainty, the Company shall not be liable for the failure of the Purchaser to benefit from any anticipated Tax efficiency as a result of a
Pre-Acquisition Reorganization. 
 (d) The Purchaser agrees that it will be
responsible for all costs and expenses associated with any Pre-Acquisition Reorganization to be carried out at its request and shall indemnify and save harmless the Company and its subsidiaries and their
respective Representatives from and against any and all liabilities, losses, damages, claims, costs, expenses, interest awards, judgments and penalties suffered or incurred by any of them in connection with or as a result of any such Pre-Acquisition Reorganization (including in respect of any reversal, modification or termination of a Pre-Acquisition Reorganization) and that any Pre-Acquisition Reorganization will not be considered in determining whether a representation or warranty of the Company under this Agreement has been breached (including where any such Pre-Acquisition Reorganization requires the consent of any third party under a Contract). If the Offer is not completed, the Purchaser shall reimburse the Company forthwith for all fees and expenses (including any
reasonable professional fees and expenses and taxes) incurred by the Company in considering or effecting all or any part of the Pre-Acquisition Reorganization and shall be responsible for any fees, expenses
and costs (including reasonable professional fees and expenses and taxes) of the Company in reversing or unwinding any Pre-Acquisition Reorganization that was effected prior to the Expiry Time. 

ARTICLE 5 

ADDITIONAL AGREEMENTS 
  

	5.1	 Acquisition Proposals 

(a) Except as expressly contemplated by this Agreement or to the extent that the Purchaser, in its sole and absolute
discretion, has otherwise consented to in writing, until the earlier of (i) the completion of a Compulsory Acquisition or Subsequent Acquisition Transaction; and (ii) the date, if any, on which this Agreement is terminated pursuant to
Section 6.1, the Company shall not and shall cause its Representatives to not, directly or indirectly through any other person: 

  
 - 64 - 

	 	(i)	 make, initiate, solicit or knowingly encourage (including by way of furnishing or affording access to
information or any site visit), or take any other action that facilitates, directly or indirectly, any inquiries or the making of any proposal or offer with respect to an Acquisition Proposal or that reasonably could be expected to lead to an
Acquisition Proposal; or 

  

	 	(ii)	 participate in any discussions or negotiations with, furnish information to, or otherwise co-operate in any way with, any person (other than the Purchaser and its subsidiaries) regarding an Acquisition Proposal or that reasonably could be expected to lead to an Acquisition Proposal, it being acknowledged
and agreed that, provided the Company is then in compliance with its obligations under this Section 5.1, the Company may (a) advise a Person who has submitted a written Acquisition Proposal of the restrictions in this Agreement, and
(b) advise a Person who has submitted a written Acquisition Proposal that their Acquisition Proposal does not constitute a Superior Proposal; or 

  

	 	(iii)	 remain neutral with respect to, or agree to, approve or recommend, or propose publicly to agree, approve or
recommend any Acquisition Proposal (it being understood that publicly taking no position or a neutral position with respect to an Acquisition Proposal for a period of three Business Days after such Acquisition Proposal has been publicly announced
shall be deemed not to constitute a violation of this Section 5.1(a)(iii)); or 

  

	 	(iv)	 make or propose publicly to make a Change of Recommendation; or 

 

	 	(v)	 accept, enter into, or propose publicly to accept or enter into, any agreement, understanding or arrangement
effecting or related to any Acquisition Proposal or potential Acquisition Proposal (other than an Acceptable Confidentiality Agreement pursuant to Section 5.1(c)); or 

 

	 	(vi)	 make any public announcement (except as required by applicable Law or the rules or policies of the TSX or NYSE
MKT after prior notice to the Purchaser) or take any other action inconsistent with the approval or recommendation of the Exeter Board of the transactions contemplated hereby. 

(b) The Company and its Representatives will and will cause its subsidiaries and their Representatives to immediately cease
any solicitation, knowing encouragement, discussion or negotiation with any person (other than the Purchaser and its subsidiaries) conducted heretofore by the Company or any of its Representatives or its subsidiaries and their Representatives with
respect to any Acquisition Proposal and, in connection therewith, the Company will discontinue access to any of its confidential information, including access to any data room, virtual or otherwise, to any person (other than access by Company
advisers and the Purchaser and its Representatives). 

  
 - 65 - 

 (c) Notwithstanding anything to the contrary contained in Section 5.1(a), in
the event that the Company receives a written Acquisition Proposal from any person after the date hereof that was not solicited by the Company and that did not otherwise result from a breach of this Section 5.1, and subject to the
Company’s compliance with Section 5.1(d), the Company and its Representatives may (i) contact such person solely to clarify the terms and conditions of such Acquisition Proposal, (ii) furnish information with respect to it to
such person pursuant to an Acceptable Confidentiality Agreement, provided that (x) the Company provides a copy of such Acceptable Confidentiality Agreement to the Purchaser promptly upon its execution or prior to providing any such information
and (y) the Company contemporaneously provides to the Purchaser any non-public information concerning the Company that is provided to such person which was not previously provided to the Purchaser or its
Representatives, and (iii) participate in any discussions or negotiations regarding such Acquisition Proposal; provided, however, that, prior to taking any action described in clauses (ii) or (iii) above, the Exeter Board determines
in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal is or could reasonably be expected to lead to a Superior Proposal and failure to take such action would violate the fiduciary
duties of such directors under applicable Law. 
 (d) The Company will promptly (and, in any event, within 24 hours) notify
the Purchaser, at first orally and thereafter in writing, of any Acquisition Proposal (whether or not in writing) received by the Company, any inquiry received by the Company that could reasonably be expected to lead to an Acquisition Proposal, or
any request received by the Company for non-public information relating to the Company in connection with an Acquisition Proposal or for access to the properties, books or records of the Company by any person
that informs the Company that it is considering making an Acquisition Proposal, including if in writing a copy of the Acquisition Proposal, a description of the material terms and conditions of such inquiry or request and the identity of the person
making such Acquisition Proposal, inquiry or request, and promptly provide to the Purchaser such other information concerning such Acquisition Proposal, inquiry or request as the Purchaser may reasonably request. The Company will keep the Purchaser
promptly and fully informed of the status and details (including all amendments) of any such Acquisition Proposal, inquiry or request. 

(e) Except as expressly permitted by this Section 5.1, neither the Exeter Board, nor any committee thereof shall:
(i) make a Change of Recommendation, (ii) accept, approve, endorse or recommend or publicly propose to accept, approve, endorse or recommend any Acquisition Proposal, (iii) permit the Company to accept or enter into, or publicly
propose to enter into (or permit any such actions in the case of the Exeter Board or any committee thereof), any letter of intent, memorandum of understanding or other Contract, agreement in principle, acquisition agreement, merger agreement or
similar agreement or understanding, other than an Acceptable Confidentiality Agreement (an “Acquisition Agreement”) with respect to any Acquisition Proposal or (iv) permit the Company to accept or enter into any Contract
requiring the Company to abandon, terminate or fail to consummate the Contemplated Transactions or providing for the payment of any break, termination or other fees or expenses to any person proposing an Acquisition Proposal in the event that the
Company completes the transactions contemplated hereby or any other transaction with the Purchaser or any of its affiliates. 

  
 - 66 - 

 (f) Notwithstanding Section 5.1(e), in the event the Company receives an
Acquisition Proposal that is a Superior Proposal from any person after the date hereof, then the Exeter Board may withdraw, modify, qualify or change in a manner adverse to the Purchaser its approval or recommendation of the Offer and/or approve or
recommend such Superior Proposal and/or enter into an Acquisition Agreement with respect to such Superior Proposal but only if: 
  

	 	(i)	 the Company has given written notice to the Purchaser that it has received such Superior Proposal that
complies with Section 5.1(d) hereof and that the Exeter Board has determined that (x) such Acquisition Proposal constitutes a Superior Proposal and (y) the Exeter Board intends to withdraw, modify, qualify or change in a manner
adverse to the Purchaser its approval or recommendation of the Offer, and/or enter into an Acquisition Agreement with respect to such Superior Proposal in each case promptly following the making of such determination, together with a summary of the
material terms of any proposed Acquisition Agreement or other agreement relating to such Superior Proposal (together with a copy of such agreement and any ancillary agreements) to be executed with the person making such Superior Proposal and, if
applicable, a written notice from the Exeter Board regarding the value or range of values in financial terms that the Exeter Board has, in consultation with its financial advisors, determined should be ascribed to any
non-cash consideration offered in the Superior Proposal; 

  

	 	(ii)	 a period of five full Business Days (such period being the “Superior Proposal Notice Period”)
shall have elapsed from the date the Purchaser received the notice from the Company referred to in Section 5.1(f)(i) and, if applicable, the notice from the Exeter Board with respect to any non-cash
consideration as contemplated in Section 5.1(f)(i), together with the summary of material terms and copies of agreements referred to therein. During the Superior Proposal Notice Period, the Purchaser shall have the right, but not the
obligation, to propose to amend the terms of the Offer and this Agreement; 

  

	 	(iii)	 the Company did not breach any provision of this Section 5.1 in connection with the preparation or making
of such Acquisition Proposal and the Company has complied with the other terms of this Section 5.1(f); 

  

	 	(iv)	 if the Purchaser has proposed to amend the terms of the Offer and this Agreement in accordance with
Section 5.1(f)(ii), the Exeter Board shall have determined in accordance with Section 5.1(g) that such Acquisition Proposal remains a Superior Proposal compared to the Offer and this Agreement as proposed to be amended by the Purchaser;

  

	 	(v)	 the Company concurrently terminates this Agreement pursuant to Section 6.1(d)(i); and

  

	 	(vi)	 the Company has previously paid, or concurrently with such termination pays, to the Purchaser the Termination
Fee. 

  
 - 67 - 

 (g) The Exeter Board will review in good faith any offer made by the Purchaser to
amend the terms of the Offer and this Agreement in order to determine, in consultation with its financial advisors and outside legal counsel, whether the proposed amendments would, upon acceptance, result in the Acquisition Proposal previously
constituting a Superior Proposal ceasing to be a Superior Proposal. The Company agrees that, subject to the Company’s disclosure obligations under applicable Securities Laws, the fact of the making of, and each of the terms of, any such
proposed amendments shall be kept strictly confidential and shall not be disclosed to any person (including without limitation, the person having made the Superior Proposal), other than the Company’s Representatives, without the
Purchaser’s prior written consent. If the Exeter Board determines that such Acquisition Proposal would cease to be a Superior Proposal as a result of the amendments proposed by the Purchaser, the Company will forthwith so advise the Purchaser
and will promptly thereafter accept the offer by the Purchaser to amend the terms of the Offer and this Agreement and the Parties agree to take such actions and execute such documents as are necessary to give effect to the foregoing. If the Exeter
Board continues to believe in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal remains a Superior Proposal and therefore rejects the Purchaser’s offer to amend the Offer and
this Agreement, if any, the Company may, subject to compliance with the other provisions hereof, terminate this Agreement in accordance with Section 6.1(d)(i) to enter into an Acquisition Agreement in respect of such Superior Proposal. 

(h) Each successive modification of any Superior Proposal shall constitute a new Superior Proposal for the purposes of
Section 5.1(f) and shall require a new five full Business Day Superior Proposal Notice Period from the date described in Section 5.1(f)(ii) with respect to such new Superior Proposal. 

(i) The Exeter Board shall reaffirm its recommendation in favour of the Offer by news release promptly after (A) the
Exeter Board has determined that any Acquisition Proposal is not a Superior Proposal if the Acquisition Proposal has been publicly announced or made; or (B) the Exeter Board makes the determination referred to in Section 5.1(g) that an
Acquisition Proposal that has been publicly announced or made and which previously constituted a Superior Proposal has ceased to be a Superior Proposal. The Purchaser shall be given a reasonable opportunity to review and comment on the form and
content of any such news release. Such news release shall state that the Exeter Board has determined that such Acquisition Proposal is not a Superior Proposal. 

(j) The Company will not become a party to any Contract with any person subsequent to the date hereof that limits or prohibits
the Company from (x) providing or making available to the Purchaser and its affiliates and Representatives any information provided or made available to such person or its officers, directors, employees, consultants, advisors, agents or other
representatives (including solicitors, accountants, investment bankers and financial advisors) pursuant to any confidentiality agreement described in this Section 5.1 or (y) providing the Purchaser and its affiliates and Representatives
with any other information required to be given to it by the Company under this Section 5.1. 

  
 - 68 - 

 (k) Unless this Agreement is terminated, the Company agrees (i) not to
release any persons from, or terminate, modify, amend or waive the terms of, any confidentiality agreement or standstill agreement or standstill provisions in any such confidentiality agreement that the Company entered into prior to the date hereof,
(ii) to promptly and diligently enforce all standstill, non-disclosure, non-disturbance, non-solicitation and similar
covenants that it has entered into prior to the date hereof or enter into after the date hereof (it being acknowledged and agreed that the automatic termination of any standstill provisions of any such agreement as the result of the entering into
and announcement of this Agreement by the Company, pursuant to the express terms of any such agreement, shall not be a violation of this subsection 5.1(k)). 

(l) Notwithstanding any of the provisions of this Section 5.1, the Exeter Board shall have the right to respond, within
the time and in the manner required by applicable Securities Laws, to any take-over bid or tender or exchange offer made for the Exeter Shares that it determines is not a Superior Proposal. 

(m) The Company shall ensure that its Representatives are aware of the provisions of this Section 5.1, and the Company
shall be responsible for any breach of this Section 5.1 by any of its Representatives. 
  

	5.2	 Expenses and Termination Fee 

(a) “Termination Fee Event” means any of the following events: 

 

	 	(i)	 an Acquisition Proposal shall have been made public or proposed publicly to the Company or the Exeter
Shareholders after the date hereof and prior to the Expiry Time, and: 

  

	 	(A)	 the Purchaser shall have exercised its termination right under Section 6.1(c)(iv) as a result of the
Minimum Tender Condition not being satisfied, and 

  

	 	(B)	 the Company shall have (x) completed any Acquisition Proposal within nine months after this
Agreement is terminated or (y) entered into an Acquisition Agreement in respect of any Acquisition Proposal or the Exeter Board shall have recommended any Acquisition Proposal, in each case, within nine months after this Agreement is
terminated, which Acquisition Proposal in either case, as it may be modified or amended, is subsequently completed (whether before or after the expiry of such nine-month period), 

provided, however, that for the purposes of this paragraph 5.2(a)(i) all references to “20%” in the definition of
Acquisition Proposal shall be changed to “50%”; or 
  

	 	(ii)	 this Agreement shall have been terminated by the Purchaser pursuant to Section 6.1(c)(i); or

  

	 	(iii)	 this Agreement shall have been terminated by the Purchaser pursuant to Section 6.1(c)(ii); or

  

	 	(iv)	 this Agreement shall have been terminated by the Company pursuant to Section 6.1(d)(i).

  
 - 69 - 

 (b) If a Termination Fee Event occurs, the Company shall pay to the Purchaser a
termination fee of $8,650,000 (the “Termination Fee”) by wire transfer in immediately available funds to an account specified by the Purchaser. The Company shall pay the Termination Fee to the Purchaser on or prior to completion of
the applicable Acquisition Proposal (in the case of a Termination Fee Event referred to in Section 5.2(a)(i)), within two Business Days following termination of this Agreement (in the case of a Termination Fee Event referred to in
Section 5.2(a)(ii) or 5.2(a)(iii)), or prior to or concurrent with termination of this Agreement (in the case of a Termination Fee Event referred to in Section 5.2(a)(iv)). If the Company does not have sufficient financial resources to pay
the Termination Fee, then it shall be a condition of (A) any Superior Proposal referred to in Section 6.1(d)(i), and (B) any share or asset acquisition referred to in Section 5.2(a)(i) where the Company has entered into any
agreement to support such share acquisition or to transfer such assets, as applicable, that the person making such Superior Proposal or acquisition, as applicable, shall advance or otherwise provide to the Company the cash required for the Company
to pay the Termination Fee, which amount shall be so advanced or provided prior to the date on which the Company is required to pay the Termination Fee. 

(c) In the event that the Purchaser terminates this Agreement pursuant to Section 6.1(c)(iv) as a result of the Minimum
Tender Condition not being satisfied then the Company shall reimburse the Purchaser in respect of the expenses it has actually incurred in respect of the Offer and this Agreement up to a maximum amount of $1,000,000 (the “Termination Expense
Reimbursement”). Such Termination Expense Reimbursement shall be made within three Business Days of a request for reimbursement. Each of the Parties hereby acknowledges that in the event the Termination Fee is paid by the Company in
accordance with Section 5.2(a) and 5.2(b), this Section 5.2(c) shall not apply and no Termination Expense Reimbursement shall be payable by the Company and, for greater certainty, if a Termination Expense Reimbursement is paid and subsequently
a Termination Fee becomes payable, then the amount of such Termination Fee shall be reduced by the amount of the Termination Expense Reimbursement. 

(d) Except as otherwise specified herein, each Party will pay its respective legal and accounting costs, fees and expenses
incurred in connection with the preparation, execution and delivery of this Agreement and all documents and instruments executed pursuant to this Agreement and any other costs, fees and expenses whatsoever and howsoever incurred, and will indemnify
and save harmless the others from and against any claim for any broker’s, finder’s or placement fee or commission alleged to have been incurred as a result of any action by it in connection with the transactions hereunder. 

(e) Each Party acknowledges that all of the payment amounts set out in this Section 5.2 are payments in consideration for
the disposition of the Purchaser’s rights under this Agreement and represent liquidated damages which are a genuine pre-estimate of the damages which the Purchaser will suffer or incur as a result of the
event giving rise to such payment and the resultant termination of this Agreement and are not penalties. The Company irrevocably waives any right that it may have to raise as a defence that any such liquidated damages are excessive or punitive. For
greater certainty, the Parties agree that the payment of an amount pursuant to this Section 5.2 in the manner provided herein is the sole and exclusive remedy of the Purchaser in respect of the event giving rise to such payment, provided,
however, that nothing contained in this Section 5.2, and no payment of any such amount, shall relieve or have the effect of relieving the Company in any way from liability for damages incurred or suffered by the Purchaser as a result of an
intentional or wilful breach of this Agreement and nothing contained in this Section 5.2 shall preclude the Company from seeking injunctive relief in accordance with Section 7.13 to restrain the breach or threatened breach of the covenants
or agreements set forth in this Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith.

Agreement may be terminated by either the Company or the Purchaser at any time prior to the Effective Time: 
  

	 	(i)	 if the Purchaser has not taken-up and paid for the Exeter Shares
deposited under the Offer by the Outside Date, except that the right to terminate this Agreement under this Section 6.1(b)(i) shall not be available to any Party whose failure to fulfil any of its obligations or breach of any of its
representations and warranties under this Agreement has been a principal cause of, or resulted in, the failure of the take-up to occur by such date or where the Purchaser has extended the Expiry Time pursuant
to this Agreement; provided, however, that if the Purchaser’s take-up and payment for Exeter Shares deposited under the Offer is delayed by (i) an injunction or order made by a Regulatory
Authority or Court of competent jurisdiction, or (ii) the Purchaser not having obtained any regulatory waiver, consent or approval which is necessary to permit the Purchaser to take up and pay for Exeter Shares deposited under the Offer, then,
provided that such injunction or order is being contested or appealed or such regulatory waiver, consent or approval is being actively sought, as applicable, this Agreement shall not be terminated by the Company or the Purchaser pursuant to this
Section 6.1(b)(i) until the earlier of the 180th day after the date of mailing of the Offer and the fifth Business Day following the date on which such injunction or order ceases to be in effect or such waiver, consent or approval is obtained,
as applicable;

otherwise prohibited, and such Law has become final and non-appealable; or 

  

	 	(iii)	 if the necessary conditional approvals or equivalent approvals, as the case may be, of the TSX, the NYSE and

manner adverse to the Purchaser, its approval or recommendation of the Offer and this Agreement (it being understood that publicly taking no position or a neutral position by the Company and/or the Exeter Board with respect to an Acquisition
Proposal for a period exceeding three Business Days after an Acquisition Proposal has been publicly announced shall be deemed to constitute such a withdrawal, modification, qualification or change), (B) the Purchaser requests that the Exeter
Board reaffirm its Board Recommendation and the Exeter Board shall not have done so by the earlier of (x) the end of the third Business Day following receipt of such request and (y) the Expiry Date (each of the foregoing a “Change
of Recommendation”), (C) the Company and/or the Exeter Board, or any committee thereof, accepts, approves, endorses or recommends any Acquisition Proposal, (D) the Company enters into an Acquisition Agreement in respect of any
Acquisition Proposal (other than an Acceptable Confidentiality Agreement permitted by Section 5.1(c)) or (E) the Company or the Exeter Board publicly proposes or announces its intention to do any of the foregoing;

agreements in this Agreement to be performed and complied with; or 

  

	 	(vi)	 the representations and warranties of the Company in Section 3.1 shall not be true and correct
(disregarding for this purpose all materiality or Material Adverse Effect qualifications contained therein) as of the Expiry Time as if made on and as of such date (except for such representations and warranties which refer to or are made as of
another specified date, in which case such representations and warranties shall not have been true and correct as of that date) except (i) as affected by transactions, changes, conditions, events or circumstances expressly permitted by this
Agreement or (ii) for breaches of representations and warranties (other than those contained in Sections 3.1(g) (Capitalization), 3.1(q) (Litigation) and 3.1(t) (Interest in Properties)) which individually or in the aggregate have not had
and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, it being understood that the representations and warranties made by the Company in Sections 3.1(g) (Capitalization), 3.1(q) (Litigation)
and 3.1(t) (Interest in Properties) must be accurate in all respects when made and as of the Expiry Time. 

  
 - 72 - 

 (d) Termination by the Company. This Agreement may be terminated by the
Company at any time prior to the Effective Time if:

that date) and except (i) as affected by transactions, changes, conditions, events or circumstances expressly permitted by this Agreement or (ii) for breaches of representations and warranties which individually or in the aggregate which
have not had and would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the Purchaser. 

  

	6.2	 Void upon Termination 

If this Agreement is terminated pursuant to Section 6.1, this Agreement shall become void and of no force and effect and
no Party will have any liability or further obligation to the other Party hereunder, except that the provisions of this Section 6.2, Section 4.2, Section 4.9(a) (solely with respect to the Purchaser’s obligation to reimburse all
fees and expenses incurred in connection with a Pre-Acquisition Reorganization), Section 5.2 and Article 7 (other than Section 7.5 and Section 7.8) shall survive any termination hereof
pursuant to Section 6.1, provided, however, that neither the termination of this Agreement nor anything contained in Section 5.2 or this Section 6.2 will relieve any Party from any liability for any intentional or wilful breach by it
of this Agreement, including any intentional or wilful making of a misrepresentation in this Agreement. Notwithstanding anything to the contrary contained in this Agreement, the Confidentiality Agreement shall survive any termination hereof pursuant
to Section 6.1. 

  
 - 73 - 

	6.3	 Notice and Cure Provisions 

If any Party determines at any time prior to the Effective Time that it intends to refuse to complete the transactions
contemplated hereby because of any unfilled or unperformed condition contained in this Agreement, such Party will so notify the other Party forthwith upon making such determination in order that the other Party will have the right and opportunity to
take such steps, at its own expense, as may be necessary for the purpose of fulfilling or performing such condition within a reasonable period of time, but in no event later than the Expiry Time. Neither the Company nor the Purchaser may elect not
to complete the transactions contemplated hereby pursuant to the conditions contained in Schedule A hereof or exercise any termination right arising therefrom and no payments will be payable as a result of such election unless forthwith and in any
event prior to the Expiry Time the Party intending to rely thereon has given a written notice to the other Party specifying in reasonable detail all breaches of covenants, representations and warranties or other matters which the Party giving such
notice is asserting as the basis for the non-fulfillment of the applicable condition precedent or the exercise of the termination right, as the case may be. If any such notice is given, provided that the other
Party is proceeding diligently to cure such matter, if such matter is susceptible to being cured, the Party giving such notice may not terminate this Agreement as a result thereof until the earlier of the Expiry Time and the expiration of a period
of 10 Business Days from such notice.

or condition waived. The rights and remedies of the Parties hereunder are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at law or in equity or otherwise. No single or partial exercise by a
Party of any right or remedy precludes or otherwise affects any further exercise of such right or remedy or the exercise of any other right or remedy to which that Party may be entitled. No waiver or partial waiver of any nature, in any one or more
instances, will be deemed or construed a continued waiver of any condition or breach of any other term, representation or warranty in this Agreement.

provision will be severed from this Agreement and the remaining provisions will continue in full force and effect so long as the economic or legal substance of the transactions contemplated herein is not affected in any material manner or would
prevent or significantly impede or materially delay the completion of the Contemplated Transactions.

this Agreement were not performed in accordance with their specific terms or were otherwise breached for which money damages would not be an adequate remedy at law. It is accordingly agreed that the Parties will be entitled to an injunction or
injunctions and other equitable relief to prevent breaches of this Agreement, any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief hereby being waived.

CONDITIONS TO THE OFFER 

Subject to the provisions of the Agreement and applicable Laws, the Purchaser shall have the right to withdraw or terminate the Offer (or

concert with the Purchaser (the “Minimum Tender Condition”); 

  

	 	(b)	 there shall have been validly deposited under the Offer and not withdrawn at the Expiry Time such number of
Exeter Shares that constitute at least 66 2/3% of the Exeter Shares outstanding at the Expiry Time on a fully-diluted basis; 

  

	 	(b)	 the Support Agreement shall not have been terminated in accordance with its terms; 

 

	 	(c)	 no Law will have been enacted, issued, promulgated, enforced, made, entered, issued or applied and no
Proceeding will otherwise have been taken under any Laws or by any Governmental Authority (whether temporary, preliminary or permanent) that makes the Offer illegal or otherwise directly or indirectly cease trades, enjoins, restrains or otherwise
prohibits completion of the Offer; 

  

	 	(d)	 there shall not have occurred, prior to the Expiry Date, a Material Adverse Effect; and

  

	 	(e)	 there shall not be pending or threatened in writing any Proceeding by any Governmental Authority or any other
person that is reasonably likely to result in any: 

  

	 	(i)	 prohibition or restriction on the acquisition by the Purchaser of any Exeter Shares or the completion of the
Offer; 

  

	 	(ii)	 prohibition or material limit on the ownership by the Purchaser of the Company or any material portion of its

 The foregoing conditions are for the exclusive benefit of the Purchaser and may be asserted by

conditions in whole or in part at any time and from time to time without prejudice to any other rights which the Purchaser may have. The failure by the Purchaser at any time to exercise any of the foregoing rights will not be deemed to be a waiver
of any such right and each such right shall be deemed to be an ongoing right which may be asserted at any time and from time to time.
