 2.5 Dealings with Payment Undertaking and
Extension of Expiry Date. 
 (a) The Parties hereto do hereby agree that effective as of the Execution Requirement Date, US$3,500,000 of
the Deposit shall be designated as the “First Option Payment” (the “First Option Payment”) (with the payment undertaking provisions thereof to be differentiated from the payment undertaking provisions of the Deposit
as provided in this section) and the Deposit shall be deemed to be the Deposit less the First Option Payment. YC shall have the right, upon the written, irrevocable designation of an additional US$3,500,000 of the Deposit as the “Second
Option Payment” (the “Second Option Payment”), to extend the Expiry Date by an additional 20 Business Days, in which case the Expiry Date shall be 45 Business Days after the Execution Requirement Date and the payment
undertaking provisions of the First Option Payment and the Second Option Payment shall be different from each other and from the Deposit as provided in this section, and the Deposit shall be deemed to be the Deposit less the First Option Payment and
the Second Option Payment. 

  
 - 14 -









 (b) If YC has made the additional designation of the Second Option Payment and extends the Expiry Date to 45
Business Days after the Execution Requirement Date, and has obtained all approvals of (i) the State-owned Assets Supervision and Administration Commission of the Peoples’ Republic of China (the “PRC”), (ii) the
Ministry of Commerce of the PRC, (iii) the National Development and Reform Commission of the PRC or (iv) the State Administration of Foreign Exchange of the PRC required of YK, YC, and/or its affiliates, as applicable, required in connection
with this Agreement and the Contemporaneous Agreement, YC shall have the further right to extend the Expiry Date by an additional 10 Business Days, in which case the Expiry Date shall be 55 Business Days after the Execution Requirement Date, by
paying to the Vendor US$1,750,000, which amount shall be deducted from the Purchase Price payable by YC at Closing. If YC does not complete the Transaction by reason of its failure to obtain any of the Buyer Regulatory Approvals set forth in item
“2” of Schedule “B”, provided that YC has used its reasonable efforts to procure such Buyer Regulatory Approvals (although YC shall not be deemed to be in derogation of its obligations to use its reasonable efforts by reason of
acts or omissions of the Vendor in connection with the procurement of such Buyer Regulatory Approvals), the Vendor shall return the US$1,750,000 payment to YC as soon as commercially practicable, but in any event within 5 Business Days of
termination of this Agreement. If YC does not complete the Transaction for any other reason, the US$1,750,000 payment shall be retained by the Vendor and shall not be refundable to YC. For greater certainty, if YC elects to exercise its right to
further extend the Expiry Date pursuant to this section 2.5(b), the First Option Payment and the Second Option Payment shall continue to be held in escrow pursuant to the Payment Undertaking and in no way shall become due and payable in cash.

 (c) The Parties do hereby agree that the payment undertaking provisions relating to the Deposit, the First Option Payment and the Second
Option Payment, as applicable, are set forth below. These items specifically relate to the Payment Undertaking, and the manner in which the Parties are to act with respect thereto so as to instruct the Bank of China as at and from the applicable
time. 
  

	 	(i)	The Parties will jointly direct the Bank of China to cancel the Payment Undertaking, if YC shall terminate this Agreement as set forth in Article 8.


  

	 	(ii)	On Closing, the Parties will jointly direct the Bank of China to pay the First Option Payment and the Deposit or the First Option Payment, the Second Option Payment and
the Deposit, if YC has exercised its right to extend the Expiry Date as provided in section 2.5(a), plus all interest earned thereon to the Vendor and such amounts will be applied toward satisfaction of the Purchase Price. 


 

	 	(iii)	On the Expiry Date, the Parties will jointly direct the Bank of China to pay the First Option Payment or the First Option Payment and the Second Option Payment, if YC
has exercised its right to extend the Expiry Date as provided in section 2.5(a), to the Vendor plus all interest accrued thereon if YC does not complete the Transaction by reason of its failure to obtain any of the Buyer Regulatory Approvals set
forth in item 1 of Schedule “B”. However, if a Material Adverse Variance has occurred in relation to the Transaction or if the Vendor shall otherwise be in breach of its Closing obligations contained in this Agreement, on the Expiry Date,
the Parties will jointly direct the Bank of China to cancel the Payment Undertaking. 


  
 - 15 -










	 	(iv)	On the Expiry Date, the Parties will jointly direct the Bank of China to cancel the Payment Undertaking if YC does not complete the Transaction by reason of its failure
to obtain any of the Buyer Regulatory Approvals set forth in item “2” of Schedule “B”, provided that YC has used its reasonable efforts to procure such Buyer Regulatory Approvals (although YC shall not be deemed to be in
derogation of its obligations to use its reasonable efforts by reason of acts or omissions of the Vendor in connection with the procurement of such Buyer Regulatory Approvals). 


 

	 	(v)	On the Expiry Date, the Parties will jointly direct the Bank of China to pay the First Option Payment and the Deposit or the First Option Payment, the Second Option
Payment and the Deposit, if YC has exercised its right to extend the Expiry Date as provided in section 2.5(a), plus all interest earned thereon to the Vendor if YC does not complete the Transaction for reasons other than those set forth in sections
2.5(c)(iii) and (iv); however, if a Material Adverse Variance has occurred in relation to the Transaction or if the Vendor shall otherwise be in breach of its Closing obligations contained in this Agreement, on the Expiry Date, the Parties will
jointly direct the Bank of China to cancel the Payment Undertaking. 

 (d) The Parties covenant and agree to provide appropriate
written demands to the Bank of China in relation to the Payment Undertaking, in the circumstances described above and in accordance with the terms of the Payment Undertaking. 
 (e) Notwithstanding anything contained in this section, if the Mann and Medge Litigation or any other Legal Proceeding in respect of the Properties, the Information, this Agreement or the Transaction
existing as at the Closing Date adversely affects YC as at the Closing Date or enjoins, restricts or prohibits, or asserts a claim or seeks a remedy that would have the effect of enjoining, restricting or prohibiting the completion of the
Transaction, the Vendor shall not be entitled to the Deposit and any part of the Deposit already paid to the Vendor shall be returned to YC by the Vendor as soon as commercially practicable. If YC has elected to exercise its right to further extend
the Expiry Date pursuant to section 2.5(b), the Vendor shall also return the US$1,750,000 payment to YC as soon as commercially practicable. In addition, all reasonable expenses of YC incurred in respect of the Transaction shall be reimbursed by the
Vendor. 
 2.6 Exclusive Dealings. From and after the date hereof, the Vendor shall not take any action, directly or indirectly,
to encourage, initiate or engage in discussions or negotiations with, or provide any information to, any Person, other than YC concerning any sale, transfer, license or assignment of the Properties or the Information or any merger, amalgamation or

in section 6.1(c), for such deposit amount, or portion thereof, the Vendor shall, as soon as commercially practicable, pay said amount to YC without set-off or deduction. 

 

	3.	REPRESENTATIONS AND WARRANTIES OF THE VENDOR 

 The Vendor represents and warrants to YC as set out in this section and acknowledges that YC is relying on such representations and warranties in connection with the Transaction and that such

3.1 Incorporation of the Vendor. The Vendor is a corporation duly incorporated, organized and subsisting under the laws of the Province of
Saskatchewan and has the corporate power, authority and capacity to execute and deliver this Agreement, to own the Properties and the Information, to sell the Properties and the Information to YC as herein contemplated and to perform its other
obligations hereunder and under the Payment Undertaking and the Covenant Escrow Agreement. No proceedings have been taken or authorized by the Vendor or by any other Person with respect to the bankruptcy, insolvency, liquidation, dissolution or
winding up of the Vendor or with respect to any amalgamation, merger, consolidation, arrangement or reorganization of, or relating to, the Vendor nor, to the knowledge of the Vendor, have any such proceedings been threatened by any other Person.

the completion of the Transaction have been duly and validly authorized by all necessary corporate action on behalf of the Vendor and each of this Agreement and the Payment Undertaking has been duly and validly executed and delivered by the Vendor
and is a valid and binding obligation of the Vendor enforceable against the Vendor in accordance with its respective terms. On Closing, the execution and delivery of the Covenant Escrow Agreement and the Closing Documents will be duly and validly
authorized by all necessary corporate action on behalf of the Vendor and each of the Covenant Escrow Agreement and the Closing Documents will be validly executed and delivered by the Vendor and valid and binding obligations of the Vendor enforceable
against the Vendor in accordance with their respective terms. As at the date hereof, there is no Legal Proceeding in progress, pending, or, to the knowledge of the Vendor, threatened against or affecting the Vendor, other than the Mann and Medge
Litigation, or affecting the title of the Vendor to any parts of the Properties or the Information at law or in equity or before or by any tribunal and, to the knowledge of the Vendor, there are no grounds on which any such Legal Proceeding might be
commenced with any reasonable likelihood of success nor is there any Order outstanding against or affecting the Vendor which, in any such case, affects adversely or might affect adversely the ability of the Vendor to enter into this Agreement, the
Payment Undertaking or the Covenant Escrow Agreement or to perform its obligations hereunder or thereunder. 

  
 - 17 -









 3.3 Qualification of the Vendor. The Vendor has the necessary corporate power, authority and
capacity to own and use the Properties and the Information. 
 3.4 Conflicting Instruments. Neither the entering into of this
Agreement or the Payment Undertaking by the Parties, nor the entering into of any agreement or other instrument contemplated hereby including without limitation, the Covenant Escrow Agreement nor the completion of the Transaction nor the performance
by the Vendor of its obligations hereunder or under the Payment Undertaking or the Covenant Escrow Agreement will: (a) conflict with, or result in the breach or violation of or default under, or cause the acceleration of any obligations of the
Vendor under, any of the terms and provisions of (i) any Applicable Law, (ii) the Articles of the Vendor or its by-laws or any resolution of the directors or shareholders of the Vendor; or (iii) subject to obtaining any Consent or Vendor
Regulatory Approval which may be required thereunder in connection with the completion of the Transaction, any Licence, Order or agreement, contract or commitment, written or oral to which the Vendor is a party or by which the Vendor is bound, or
(c) result in the creation of any Lien on any part of the Properties or the Information. 
 3.5 Regulatory Approvals.
Except as set forth in Schedule “C”, no Regulatory Approval or filing with, notice to, or waiver from any Governmental Authority or other Person is required to be obtained or made by the Vendor in connection with the execution, delivery
and performance by the Vendor of its obligations under this Agreement, the Payment Undertaking, the Covenant Escrow Agreement or the Closing Documents or the consummation of the Transaction. The Vendor has no reason to believe that it will not be
able to obtain on or before Closing, the Vendor Regulatory Approval. 
 3.6 Title to Properties. The Vendor has complied in all
respects with the Regulations. The Properties are in good standing under the laws of the Province of Saskatchewan, all assessment work required to maintain the Properties in good standing has been performed and all fees of Governmental Authorities
have been paid and all filings required to maintain the Properties in good standing have been properly and timely recorded or filed with appropriate Governmental Authorities and the Vendor has no knowledge of any conflicting mineral rights. The
Properties are properly and accurately described in Schedule “A” hereto. 
 The Vendor is the owner of a 100% registered and
beneficial right, title and interest in and to all parts of the Properties and the Information with good and marketable title thereto and each part of the Properties and the Information is free and clear of all Liens and there is no adverse claim or

 The Vendor does not own any real property related to the Properties (whether or not the same overlay the
Properties). The Vendor has no knowledge that the owners of the Surface Lands will fail to grant access to any owner of the Properties in, over and along the Surface Lands as and when the Properties are to be converted to leases or that such owners
will create impediments to the acquisition of the Surface Lands or that the Government of Saskatchewan will intervene in the process relative to the acquisition of the Surface Lands by an owner of the Properties in a manner which is adverse to the
interests of any such owner. 
 The Vendor has not received notice from the Government of Saskatchewan that, upon application, the Government of
Saskatchewan will fail to convert the Properties to leases and that the same will therefore be subject to termination notwithstanding the fact that the owner shall be in full compliance with the terms thereof and Applicable Law. 

The Vendor has not received notice from the Government of Saskatchewan that the boundaries of the Properties overlap with rights of third Persons and are
therefore subject to change. No part of the Properties have been taken or expropriated by any tribunal or other body having power of expropriation, nor has any Legal Proceeding or notice in respect of any such expropriation been commenced, given or
threatened. 
 Neither the Vendor nor, to the Vendor’s knowledge, the Government of Saskatchewan is in breach of any of the provisions of
the Properties and (subject to obtaining any Consents and Vendor Regulatory Approval to the completion of the Transaction), the completion of the Transaction will not afford the Government of Saskatchewan the right to terminate the Properties nor
will the completion of the Transaction result in any additional or more onerous obligation on YC with respect to the Properties. 
 The Vendor
has not sublet, assigned, licensed or otherwise conveyed any rights in and to any parts of the Properties or the Information to any other Person. The Properties have never suffered any Material Adverse Effect. 

Notwithstanding any other provision in this Agreement, YC acknowledges and agrees that the Vendor in no way represents and warrants as to Her Majesty the
Queen in Right of Saskatchewan’s title to the “subsurface minerals” (as defined in the Regulations) listed in the Properties and the right to explore and prospect for “subsurface minerals” (as defined in the Regulations)
conveyed by the Properties is subject to any and all defects in, and Liens against, Her Majesty the Queen in Right of Saskatchewan’s ownership share in the “subsurface minerals” (as defined in the Regulations). The Vendor has no
knowledge of and has not received notice from any Governmental Authority in respect of any such defects in or Liens against Her Majesty the Queen in Right of Saskatchewan’s ownership share in the “subsurface minerals” (as defined in
the Regulations).

Surface Lands by the Vendor. To the knowledge of the Vendor, no claim has ever been asserted and there are no present circumstances which could reasonably form the basis for the assertion of any claim against the Vendor for Losses of any kind as a
direct or indirect result of the presence on or under or the escape, seepage, leakage, spillage, discharge, emission or release from the Surface Lands of any Hazardous Substance. 
 The Vendor has not used any of the Surface Lands to refine, treat, dispose, produce or process Hazardous Substances except in compliance with all Environmental Laws and Environmental Permits held by the
Vendor. 
 Neither the Vendor nor any other person responsible under Environmental Laws for acts of the Vendor has been convicted of an offence
or been subjected to any Legal Proceeding relating to Environmental Laws or been subject to any Order or other sanction requiring investigation or remediation of any real property or been fined or otherwise sentenced for non-compliance with any
Environmental Laws and has not settled any prosecution or other proceeding short of conviction in connection therewith.

Vendor shall deliver to YC a legal opinion from counsel acceptable to YC, acting reasonably, and in form and content satisfactory to YC, subject to reasonable qualifications, as to the due incorporation and organization of the Vendor, the corporate
power and authority of the Vendor, the receipt of all necessary approvals by the Vendor, the enforceability of this Agreement, the Payment Undertaking and the Covenant Escrow Agreement as against the Vendor and the non-conflict of this Agreement,
the Payment Undertaking and the Covenant Escrow Agreement with respect to the constating documents of the Vendor and any Applicable Laws. 

  
 - 26 -









 (g) During the Interim Period, YC, YK, or the Buyer shall have received no variance in information relating
to the Properties which would lead a purchaser, acting reasonably, to consider that such variance would have a material adverse effect on the Properties. 
 (h) The Buyer Regulatory Approvals shall have been granted, obtained and received unconditionally or on terms satisfactory to YC, YK, or the Buyer, as applicable. For greater certainty, and as set out in
section 2.3, the regulatory approval set forth in item 2 of Schedule “B” shall be applied for and will be granted, obtained and received after the Transaction has been deemed to be closed in escrow and no longer affected by the Expiry
Date. 
 (i) No Order shall have been made and no Legal Proceeding shall have been commenced or shall be pending or threatened against the other
Party or its affiliates or any parts of the Properties which would adversely affect YC or which enjoins, restricts or prohibits, or which asserts a claim or seeks a remedy that would have the effect of enjoining, restricting or prohibiting the
completion of the Transaction. 
 (j) The Contemporaneous Agreement shall have been executed and delivered and the transactions contemplated
thereunder shall be completed simultaneously with this Transaction. 
 (k) The Vendor shall have been granted, obtained and received the Vendor
Regulatory Approval which shall have been granted, obtained and received unconditionally or on terms satisfactory to YC, acting reasonably. 

(l) YC shall have received, as and by way of the “Closing Documents” (the “Closing Documents”) such other agreements,
certificates, affidavits, statutory declarations, instruments of transfer and other documentation reasonably required by YC to implement the Transaction, all of which shall be satisfactory in form and substance to counsel for YC, acting reasonably.

 (m) YC, the Vendor and the Escrow Agent shall have executed and delivered the Covenant Escrow Agreement and the Vendor shall have deposited
US$5,000,000 (as and when received from YC) into escrow with the Escrow Agent pursuant to such agreement. For greater certainty, any Order obtained pursuant to the Mann and Medge Litigation or any other Legal Proceeding existing as at the date
hereof will not attach to the US$5,000,000 placed into escrow pursuant to the Covenant Escrow Agreement. 
 If any condition in this section has
not been fulfilled on or before the Closing Date or if any such condition is or becomes impossible to satisfy, other than as a result of the failure of YC to comply with its obligations under this Agreement, then YC in its sole discretion may,
without limiting any rights or remedies available to YC at law or in equity, either terminate this Agreement by written notice to the Vendor, in which case, the provisions of sections 2.5(c)(i), (iv) or (v) shall be applicable or waive
compliance with any such condition without prejudice to its right of termination in the event of non-fulfilment of any other condition.

	7.	CONDITIONS FOR THE BENEFIT OF THE VENDOR 


7.1 Vendor’s Conditions. The Vendor shall not be obligated to complete the Transaction unless, at or before the Closing Time, each of
the conditions listed below in this section has been satisfied, it being understood that the said conditions are included for the exclusive benefit of the Vendor: 
 (a) The representations and warranties of YC in this Agreement shall be true and correct on the Closing Date. 
 (b) YC shall have performed and complied with all of the terms and conditions in this Agreement and the Payment Undertaking on its part to be performed or complied with on or before the Closing Date.

 (c) As evidence of the satisfaction of the conditions in sections 7.1 (a) and (b), YC shall deliver to the Vendor at the Closing Time a
certificate of YC confirming the matters in sections 7.1 (a) and (b) and to the effect that as of the Closing Time all other conditions set forth in this section have been satisfied. The certificate shall be signed by two senior executive
officers of YC acceptable to the Vendor, acting reasonably. Notwithstanding the foregoing, the receipt of such certificate and the completion of the Transaction shall not constitute a waiver (in whole or in part) of, or have the effect of modifying
or qualifying in any way, any of the representations and warranties of YC made in or pursuant to this Agreement, each of which shall survive the Closing and remain in full force and effect for the benefit of the Vendor as provided in Article 9.

 (d) YC and the Buyer shall have delivered to the Vendor a legal opinion from counsel acceptable to the Vendor, acting reasonably, and in form
and content satisfactory to the Vendor subject to reasonable qualifications, as to the due incorporation and organization of YC and the Buyer, the corporate power and authority of YC and the Buyer, the receipt of all necessary approvals by YC and
the Buyer and the enforceability of this Agreement, the Payment Undertaking and the Covenant Escrow Agreement as against YC and the Buyer and the non-conflict of this Agreement, the Payment Undertaking and the Covenant Escrow Agreement with respect
to the constating documents of YC and the Buyer and any Applicable Laws. 
 (e) The Vendor Regulatory Approval shall have been granted, obtained
and received unconditionally or on terms satisfactory to the Vendor, acting reasonably. 
 (f) No Order shall have been made and no Legal
Proceeding shall have been commenced or shall be pending or threatened against the other Party or its affiliates or which enjoins, restricts or prohibits, or which asserts a claim or seeks a remedy that would have the effect of enjoining,
restricting or prohibiting the completion of the Transaction. 

  
 - 28 -









 If any condition in this section has not been fulfilled on or before the Closing Date or if any such
condition is or becomes impossible to satisfy, other than as a result of the failure of the Vendor to comply with its obligations under this Agreement, then the Vendor in its sole discretion may, without limiting any rights or remedies available to
the Vendor at law or in equity, either terminate this Agreement by written notice to YC, in which case the provisions of sections 2.5(c)(iii), (iv) or (v) shall be applicable, or waive compliance with any such condition without prejudice
to its right of termination in the event of non-fulfilment of any other condition. 
  

	8.	DAMAGE OR EXPROPRIATION 

 8.1 Damage
or Expropriation. If, prior to the Closing Time, all or any substantial portion of the Properties shall be expropriated or seized by any Governmental Authority or any other Person in accordance with Applicable Law, or if notice of any such
expropriation or seizure shall have been given in accordance with Applicable Law, the Vendor shall forthwith advise YC of such appropriation or seizure or receipt of notice thereof, and shall provide applicable details of such appropriation or
seizure, and YC shall have the option, exercisable by notice to the Vendor given prior to the Closing Date to terminate this Agreement and not complete the Transaction, in which case YC shall be released from all obligations hereunder as of and from
the giving of such notice or the option to complete the Transaction with a reduction of the Purchase Price by the net amount equal to the replacement cost of the Properties so expropriated or seized (based on the Properties Allocation). In the event
that YC shall exercise its option to terminate this Agreement set forth in this Article 8, the Parties shall sign a joint direction to the Bank of China forthwith and authorize the Bank of China to cancel the Payment Undertaking. 

 

	9.	INDEMNIFICATION AND LIMITATIONS 

 9.1
Indemnification by the Vendor. The Vendor shall indemnify, defend and save harmless YC from and against any and all Losses suffered or incurred by YC, as a direct or indirect result of, or arising in connection with or related in any
manner whatever to a Third Party Claim. 
 9.2 Survival of Representations and Warranties. The covenants, representations and
warranties, and indemnities of the Vendor and YC set forth in this Agreement shall survive the Closing for a period of 18 months, other than in respect of liability for Losses in connection with the Mann and Medge Litigation or any other Legal
Proceeding in respect of the Properties, the Information, this Agreement or the Transaction existing as at the Closing Date, which shall survive until the end of the applicable appeal period or the claim is settled or dismissed, after which time the
Vendor and YC shall be released from all obligations in respect of such covenants, representations and warranties, and indemnities, except with respect to any claim in respect of any Losses of which a Party gives notice in writing to the other Party
(setting out in reasonable detail the nature of such claim and the approximate amount of the Losses arising as a result thereof) before the expiration of such period. For greater certainty and notwithstanding anything contained herein, YC may bring
a claim for Losses in respect of a breach by the Vendor of its representations and warranties contained in this Agreement. 

  
 - 29 -









 9.3 Notice of Third Party Claims. If YC receives notice of the commencement or assertion of
any Third Party Claim, YC shall give the Vendor reasonably prompt notice thereof, but in any event no later than 30 days after receipt of notice of such Third Party Claim. The notice to the Vendor shall describe the Third Party Claim in reasonable
detail and shall indicate, if reasonably practicable, the estimated amount of the Losses that have been or may be sustained by YC. 
 9.4
Defence of Third Party Claims. The Vendor may participate in or assume the defence of any Third Party Claim by giving notice to that effect to YC not later than 30 days after receiving notice of the Third Party Claim (the “Notice
Period”). The Vendor’s right to do so shall be subject to the rights of any insurer or other party who has potential liability in respect of that Third Party Claim. The Vendor shall pay all of its own expenses of participating in or
assuming such defence. YC shall co-operate in good faith in the defence of each Third Party Claim, even if the defence has been assumed by the Vendor and may participate in such defence assisted by counsel of its own choice at its own expense. If YC
has not received notice within the Notice Period that the Indemnifying Party has elected to assume the defence of such Third Party Claim, YC may, at its option, elect to settle or compromise the Third Party Claim or assume such defence, assisted by
counsel of its own choosing and the Indemnifying Party shall be liable for all reasonable costs and expenses paid or incurred in connection therewith and any Losses suffered or incurred by YC with respect to such Third Party Claim. If the Vendor
elects to assume the defence of a Third Party Claim under this section, the Vendor shall not have the right thereafter to contest its liability for such claim. 
 9.5 Assistance for Third Party Claims. The Vendor and YC will use all reasonable efforts to make available to the Party which is undertaking and controlling the defence of any Third Party
Claim (the “Defending Party”), those employees and other persons whose assistance, testimony or presence is necessary to assist the Defending Party in evaluating and in defending any Third Party Claim and all documents, records and
other materials in the possession of such Party reasonably required by the Defending Party for its use in defending any Third Party Claim and all documents, records and other materials in the possession of such Party reasonably required by the
Defending Party for its use in defending any Third Party Claim and shall otherwise cooperate with the Defending Party. The Vendor shall be responsible for all reasonable expenses associated with making such documents, records and materials available
and for all reasonable expenses of any employees or other persons made available by YC to the Vendor hereunder, which expense shall not exceed the actual cost to YC associated with such employees and other persons. 

9.6 Settlement of Third Party Claims. If the Vendor elects to assume the defence of any Third Party Claim as provided in section 9.4, the
Vendor shall not be liable for any legal expenses subsequently incurred by YC in connection with the defence of such Third Party Claim following the receipt by YC of notice of such assumption. However, if the Indemnifying Party fails to take
reasonable steps necessary to defend diligently such Third Party Claim within 30 days after receiving notice from YC that YC believes on reasonable grounds that the Indemnifying Party has failed to take such steps, YC may, at its option, elect to
assume the defence of and to negotiate, settle or compromise the Third Party Claim assisted by counsel of its own choosing and the Vendor shall also be liable for all reasonable costs and expenses paid or incurred in connection therewith. The Vendor
shall not, without the prior written consent of YC, enter into any compromise or settlement of a Third Party Claim, which would lead to liability or create any other obligation, financial or otherwise, on YC. 

  
 - 30 -









 9.7 Failure to Give Timely Notice. A failure to give timely notice as provided in this Article
shall not affect the rights or obligations of any Party except and only to the extent that, as a result of such failure, any Party which was entitled to receive such notice was deprived of its right to recover any payment under its applicable
insurance coverage or was otherwise directly and materially damaged as a result of such failure. 
 9.8 Reductions and
Subrogation. If the amount of any Losses at any time subsequent to the making of an indemnity payment in respect of those Losses is reduced by any recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to
any claim, recovery, settlement or payment by or against any other Person, the amount of such reduction (less any costs, expenses (including taxes) or premiums incurred in connection therewith), shall promptly be repaid by YC to the Vendor. Upon
making a full indemnity payment, the Vendor shall, to the extent of such indemnity payment, be subrogated to all rights of YC against any third party that is not an affiliate of YC in respect of the Losses to which the Indemnity Payment relates.
Until YC recovers full payment of its Losses, any and all claims of the Vendor against any such third Person on account of such Indemnity Payment shall be postponed and subordinated in right of payment to YC’s rights against such third Person.
Without limiting the generality or effect of any other provision hereof, YC and the Vendor shall duly execute upon request all instruments reasonably necessary to evidence and perfect such postponement and subordination. 

9.9 Tax Effect. If any payment for indemnification received by YC would constitute taxable income to YC, the Vendor shall pay to YC at the
same time and on the same terms, as to interest and otherwise, as the indemnity payment an additional amount sufficient to place YC in the same after-tax position as it would have been if the indemnity payment had been received tax-free. 

9.10 Payment and Interest. All Losses in respect of a Third Party Claim shall bear interest at a rate per annum equal to the Prime Rate,
calculated and payable monthly, both before and after judgment, with interest on overdue interest at the same rate, from the date that YC disbursed funds, suffered damages or losses or incurred a loss, liability or expense in respect of the
applicable Losses in respect of a Third Party Claim, to the date of payment by the Vendor to YC. 
 9.11 Additional Rules and
Procedures. If any Third Party Claim is of a nature such that YC is required by Applicable Law to make a payment to any Person with respect to such Third Party Claim before the completion of settlement negotiations or related legal
proceedings, YC may make such payment and the Vendor shall, forthwith after demand by YC, reimburse YC for any such payment. If the amount of any liability under the Third Party Claim in respect of which such a payment was made, as finally
determined, is less than the amount which was paid by the Vendor to YC, YC shall, forthwith after receipt of the difference from the third Person, pay such difference to the Vendor. YC and the Vendor shall co-operate fully with each other with
respect to Third Party Claims, shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available) and shall each designate a senior officer who will keep himself
informed about and be prepared to discuss the Third Party Claim with his counterpart and with legal counsel at all reasonable times. 

  
 - 31 -









 9.12 Limitations. Notwithstanding anything else in this Agreement, the maximum aggregate
liability of the Vendor on the one hand and YC on the other hand, in respect of all claims for Losses under this Agreement (including, without limitation, indemnification under section 9.1 and Losses resulting from breaches of the representations
and warranties, and covenants contained in this Agreement) shall not exceed the amount of the Purchase Price, in the aggregate. Additionally, the liability of the Vendor shall be allocated on a Property by Property basis, pursuant to the Properties
Allocation, such that its liability in respect of each Property shall be capped at that Property’s Allocation. In the event that the Vendor pays a claim for Losses to YC for the full amount of any Property, including without limitation, the
Information with respect thereto, which payment is irreversible and non-refundable, the relevant Property, including without limitation, the Information with respect thereto, shall be transferred by YC to the Vendor or as it may otherwise direct,
without any further or other consideration. 
 9.13 GST Gross Up. If any payment made by the Vendor or YC pursuant to this Article
9 is deemed by the Excise Tax Act (Canada) to include GST, or is deemed by any applicable provincial or territorial legislation to include a similar value added or multi-staged tax, the amount of such payment shall be increased accordingly.

  

	10.	MISCELLANEOUS 

 10.1 Further
Assurances. Each Party shall from time to time execute and deliver or cause to be executed and delivered all such further documents and instruments and do or cause to be done all further acts and things as the other Party may, before or
after the Closing Time, reasonably require as being necessary or desirable in order to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement or any provision hereof. 

10.2 Public Announcements. Except to the extent required by Applicable Law, each Party agrees that no disclosure or public announcement
regarding this Agreement or the Transaction shall be made by either Party without the prior written consent of the other Party (which consent may not be unreasonably withheld or delayed and may be given either generally or in a specific case or
cases and may be subject to conditions). For the avoidance of doubt, both Parties agree that YC and Acron, the Vendor’s parent company, are permitted to make public announcement(s) and other disclosure regarding this Agreement or the
Transaction as may be required under applicable listing rules of the stock exchanges on which the shares of YC or Acron are listed.
