No failure, delay or omission by the Lender to exercise or enforce any rights or remedies under this Agreement or any security collateral hereto shall constitute a waiver thereof or of any other rights or remedies of the Lender.

(vi) A creditor shall take or purport to take possession or to assert a prior claim, hypothec or lien in respect of any substantial part of the property of the Borrower and such procedure is not contested in good faith by the Borrower immediately upon such event, or if a lien, execution, distress or any process of any court be levied or enforced against any of the foregoing and remain unsatisfied for such period as would permit such prope1iy or such part thereof to be sold thereunder;

2

(vii) A resolution is passed or a petition filed for the wind-up or liquidation of the Borrower or if the Borrower institutes proceedings under any bankruptcy, insolvency or analogous law or is adjudicated as bankrupt or insolvent, or consents to (or fails to contest in good faith) the institution of bankruptcy or insolvency proceedings against it or makes (or serves notice of intention to make) any proposal under any bankruptcy, insolvency or analogous laws, or consents (or fails to contest in good faith) to the filing of any such petition or to the appointment of a receiver of, or of any substantial part of, the property of the Borrower or makes a general assignment for the benefit of creditors, or makes or agrees to make any bulk sale without complying with the provisions of any applicable bulk sale provision, or admits (in writing or otherwise) its inability to pay its debts generally as they become due, or ceases or threatens to cease to carry on business as a going concern, or takes corporate action in furtherance of any of the aforesaid purposes; or

(viii) In the event of any breach or default by the Borrower of its obligations, undertakings, covenants, representations and warranties pursuant to this Loan Agreement.

(c) Should an Event of Default occur, the Lender may, at its option, exercise its rights by any act, proceeding, recourse or procedure authorized or permitted by law and may file its proof and any other documents necessary or desirable so that the request of the Lender may be considered in any liquidation or other proceeding with respect to the Borrower.

(d) No remedy herein conferred upon or reserved to the Lender is intended to be exclusive of any other remedy, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now existing or hereafter to exist by law or by statute.

(e) The delay or omission of the Lender to exercise any recourse mentioned above shall not invalidate any such recourse nor be interpreted as a waiver of any default hereunder.

8. Security Undertaking

This loan is granted on an unsecured basis. The Borrower agrees and covenants not to grant security over any of its assets to any third party other than the Lender unless the Borrower has granted the same security to the Lender (in form and substance satisfactory to the Lender) to secure the Borrower's obligations hereunder on a super senior basis ahead of all other security, provided however that this provision shall not apply to any security over the assets of the Borrower granted to Anglo Pacific or any of its affiliates pursuant to a royalty agreement.

11. Restrictive Covenants

In addition to all other covenants and obligations contained in this Agreement, the Borrower agrees and covenants as follows:

(a) the Borrower shall not incur or permit any indebtedness, other than: (i) indebtedness with a maturity date later than June 30, 2022; or (ii) indebtedness under this Amended Loan Agreement.

(b) the Borrower shall not make any voluntary or mandatory payments of interest, fees, principal or any other amounts under any loan agreements entered into on or after September 30, 2021 until such time as all indebtedness under this Amended Loan Agreement has been repaid in its entirety.

12. Assigns, Successors and Governing Law

This Agreement shall not be assignable by the Borrower without the prior written consent of the Lender. This Agreement shall ensure to the benefit of and be binding upon the respective successors of the Borrower and the Lender and the assigns of the Lender and the permitted assigns of the Borrower. This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario. This Amended Loan Agreement amends, restates and replaces the Original Loan Agreement in its entirety.

13. Additional Amounts

Except as required by applicable law or expressly contemplated herein, all payments of any kind made under this Loan Agreement to the Lender shall be made free and clear and without any present or future deduction, withholding, charge or levy on account of taxes, without setoff or counterclaim. If any taxes are required by applicable law to be deducted, withheld, charged or levied by the Borrower on any such payment, the Borrower shall pay to the Lender, in addition to such payment, such additional amounts as are necessary to ensure that the net payment received by the Lender (net of any such taxes, including any taxes required to be deducted, withheld, charged or levied on any such additional amounts) equals the full payment that the Lender would have received had no such deduction, withholding, charge or levy been required.

14. Interest Act and Criminal Rate of Interest

Each interest rate which is calculated under this Agreement on any basis other than a full calendar year (the "deemed interest period") is, for the purposes of the Interest Act (Canada), equivalent to a yearly rate calculated by dividing such interest rate by the actual number of days in the deemed interest period, then multiplying such result by the actual number of days in the calendar year (365 or 366).

In no event shall the aggregate "interest" (as defined in Section 347 (the "Criminal Code Section") of the Criminal Code (Canada)) payable to the Lender under this Agreement exceed the effective annual rate of interest lawfully permitted under the Criminal Code Section. Further, if any payment, collection or demand pursuant to this Agreement in respect of such "interest" is determined to be contrary to the provisions of the Criminal Code Section, such payment, collection, or demand shall be deemed to have been made by mutual mistake of the Lender and the Borrower and such "interest" shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in the receipt by the Lender of interest at a rate not in contravention of the Criminal Code Section.

15. Expenses; Indemnity

The Borrower shall pay all reasonable and documented legal fees and disbursements and other out-of- pocket expenses incurred by the Lender in connection with the preparation of this Agreement and all ancillary documentation, the administration of the Loan, and enforcement of the Lender's rights and remedies under or in connection with this Agreement, and any other documentation or actions contemplated thereby.

The Borrower agrees to indemnify and hold harmless the Lender and each of its directors, officers, employees, attorneys, advisors and affiliates (all such persons and entities being referred to hereafter as "Indemnified Persons") tram and against any and all actions, suits, proceedings (including any investigations or inquiries), claims, losses, damages, liabilities or expenses of any kind or nature whatsoever (excluding indirect or consequential damages and claims for lost profits) which may be incurred by or asserted against or involve any Indemnified Person as a result of or arising out of or in any way related to or resulting from this Agreement and, upon demand, to pay and reimburse any Indemnified Person for any legal or other out-of-pocket expenses incurred in com1ection with investigating, defending or preparing to defend any such action, suit, proceeding (including, without limitation, any inquiry or investigation) or claim (whether or not any Indemnified Person is a party to any action or proceeding out of which any such expenses arise); provided, however, the Borrower shall not be obligated to indemnity pursuant to this paragraph any Indemnified Person against any loss, claim, damage, expense or liability to the extent it resulted from the gross negligence or wilful misconduct of such Indemnified Person as finally determined by a court of competent jurisdiction. The indemnities granted under this Agreement shall survive any termination of the Loan.
