Except in respect of the Initial Debentures, the form of which is provided for herein, the Debentures of each series shall be substantially in such form or forms (not inconsistent with this Indenture) as shall be established herein or by or pursuant to one or more resolutions of the Board of Directors (or to the extent established pursuant to, rather than set forth in, a resolution of the Board of Directors, in an Officer’s Certificate detailing such establishment) or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform to general usage, all as may be determined by the directors or officers of the Corporation executing such Debentures on behalf of the Corporation, as conclusively evidenced by their execution of such Debentures.

Section 2.4 Form and Terms of Initial Debentures

(1)The first series of Debentures (the “Initial Debentures”) authorized for issue immediately is limited to an aggregate principal amount of $17,000,000 and shall be designated as “10.0% Subordinated Unsecured Convertible Debentures”.

(2)The Initial Debentures shall be dated as of the date of closing of the Offering and shall mature on May 14, 2024 (the “Maturity Date” for the Initial Debentures).

(3)The Initial Debentures shall bear interest from the date of issue at the rate of 10.0% per annum (based on a year of 360 days composed of twelve 30-day months), payable in annual payments in arrears on December 31 in each year (with the exception of the first interest payment, which will include interest from and including the date of closing of the Offering as set forth below), the first such payment to fall due on December 31, 2021 and the last such payment (representing interest payable from the last Interest Payment Date to, but excluding, the Maturity Date of the Initial Debentures) to fall due on May 14, 2024, payable after as well as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded annually. For certainty, the first interest payment will include interest accrued from and including the date of closing of the Offering to, but excluding, December 31, 2021, which will be equal to $37.22 for each $1,000 principal amount of Initial Debentures. Each subsequent interest payment, other than the final interest payment, will be equal to $100 for each $1,000 principal amount of Initial Debentures. Any payment required to be made on any day that is not a Business Day will be made

​

​

- 12 -

on the next succeeding Business Day. The record date for the payment of interest on the Initial Debentures will be that date which is five Business Days prior to each Interest Payment Date.

(4)The Initial Debentures will rank pari passu with each other series of Debentures issued under this Indenture or under indentures supplemental to this Indenture (regardless of their actual date or terms of issue) and, except as prescribed by law, with all other existing and future unsecured indebtedness of the Corporation.

(5)Upon and subject to the provisions and conditions of Article 6 and Section 3.6, the holder of each Initial Debenture shall have the right at such holder’s option, at any time prior to the close of business on the earliest of (i) the Business Day immediately preceding the Maturity Date of the Initial Debentures; (the “Time of Expiry” for the purposes of Article 6 in respect of the Initial Debentures), to convert any part, being $1,000 or an integral multiple thereof, of the principal amount of a Debenture into Common Shares at the Conversion Price in effect on the Date of Conversion. Notwithstanding the foregoing, no Initial Debentures may be converted on an Interest Payment Date or during the five Business Days preceding each Interest Payment Date.

(6)The Conversion Price in effect on the date hereof for each Common Share to be issued upon the conversion of Initial Debentures shall be equal to $0.36 such that approximately 2,777 Common Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted. Except as provided below, no adjustment in the number of Common Shares to be issued upon conversion will be made for dividends or distributions on Common Shares issuable upon conversion, the record date for the payment of which precedes the date upon which the holder becomes a holder of Common Shares in accordance with Article 6, or for interest accrued on Initial Debentures surrendered. No fractional Common Shares will be issued, and the number of Common Shares so issuable will be rounded down to the nearest whole number. The Conversion Price applicable to, and the Common Shares, securities or other property receivable on the conversion of, the Initial Debentures is subject to adjustment pursuant to the provisions of Section 6.4. Holders converting their Initial Debentures will receive, in addition to the applicable number of Common Shares, accrued and unpaid interest (less any taxes required to be deducted) in respect of the Initial Debentures surrendered for conversion up to but excluding the Date of Conversion from, and including, the most recent Interest Payment Date. The Conversion Price will not be adjusted for accrued interest.

(7)Notwithstanding any other provisions of this Indenture, if a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the Person or Persons entitled to receive Common Shares in respect of the Debenture so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date and, for clarity, any interest payable on such Debentures will be for the account of the holder of record of such Debentures at the close of business on the relevant record date.

(8)The Initial Debentures shall be issued in denominations of $1,000 and integral multiples of $1,000. Each Initial Debenture and the certificate of the Trustee endorsed thereon shall be issued in substantially the form set out in Schedule A, with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the Board of Directors executing such Initial Debenture in accordance with Section 2.7 hereof, as conclusively evidenced by their execution of an Initial Debenture. Each Initial Debenture shall additionally bear such distinguishing letters and numbers as the Trustee shall approve.

​

​

- 13 -

Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be, approved by a resolution of the Board of Directors, or as specified in an Officer’s Certificate. The Initial Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another.

(9)The Initial Debentures shall be issued in the form of one or more Debenture Certificates, which shall bear the U.S. Legend, if applicable, and as Uncertificated Debentures including by way of issuance under the DRS.

(10)The Trustee shall be provided with the documents and instruments referred to in Sections 2.5(b), 2.5(c) and 2.5(d) with respect to the Initial Debentures prior to the issuance of the Initial Debentures.

The Corporation may from time to time request the Trustee to Authenticate and deliver Additional Debentures of any series by delivering to the Trustee the documents referred to below in this Section 2.5 whereupon the Trustee shall Authenticate such Debentures and cause the same to be delivered in accordance with the Written Direction of the Corporation referred to below or pursuant to such procedures acceptable to the Trustee as may be specified from time to time by a Written Direction of the Corporation. The maturity date, issue date, interest rate (if any) and any other terms of the Debentures of such series shall be set forth in or determined by or pursuant to such Written Direction of the Corporation and procedures.

(2)If the Corporation issues Debentures in a non-certificated format, Beneficial Holders of such Debentures registered and deposited with CDS shall not receive Debenture Certificates in definitive form and shall not be considered owners or holders thereof under this Indenture or any supplemental indenture.

(3)All references herein to actions by, notices given or payments made to, Debentures shall, where Debentures are held through CDS, refer to actions taken by, or notices given or payments made to, CDS upon instruction from the Participants in accordance with its rules and procedures. For the purposes of any provision hereof requiring or permitting actions with the consent of or the direction of Debentureholders evidencing a specified percentage of the aggregate Debentures outstanding, such direction or consent may be given by Beneficial Holders acting through CDS and the Participants owning Debentures evidencing the requisite percentage of the Debentures. The rights of a Beneficial Holder whose Debentures are held established by law and agreements between such holders and CDS and the Participants upon instructions from the Participants. Each Trustee and the Corporation may deal with CDS for all purposes (including the making of payments) as the authorized representative of the respective Debentures and such dealing with CDS shall constitute satisfaction or performance, as applicable, of their respective obligations hereunder.

(4)For so long as Debentures are held through CDS, if any notice or other communication is required to be given to Debentureholders, the Trustee will give such notices and communications to CDS.

Section 2.7 Execution of Debentures

All Debenture Certificates shall be signed (either manually or by facsimile or other electronic signature) by any one authorized director or officer of the Corporation holding office at the time of signing. A facsimile or electronic signature upon a Debenture shall for all purposes of this Indenture be deemed to be the signature of the person whose signature it purports to be. Notwithstanding that any person whose signature, either manual or in facsimile or electronic form, appears on a Debenture as a director or officer may no longer hold such office at the date of the Debenture or at the date of the certification and delivery thereof, such Debenture shall be valid and binding upon the Corporation and entitled to the benefits of this Indenture.

Section 2.8 Certification

(1)No Debenture Certificate shall be issued or, if issued, shall be obligatory or shall entitle the holder to the benefits of this Indenture, until it has been manually certified by or on behalf of the Trustee substantially in the form set out in this Indenture, in the relevant supplemental indenture, or in some other form approved by the Trustee. Such certification on any Debenture Certificate shall be conclusive evidence

that such Debenture is duly issued, is a valid obligation of the Corporation and the holder is entitled to the benefits hereof.

(2)The certificate of the Trustee signed on the Debentures Certificates, or interim Debentures hereinafter mentioned, shall not be construed as a representation or warranty by the Trustee as to the validity of this Indenture or of the Debentures or interim Debentures or as to the issuance of the Debentures or interim Debentures and the Trustee shall in no respect be liable or answerable for the use made of the Debentures or interim Debentures or any of them or the proceeds thereof. The certificate of the Trustee on the Debenture Certificates or interim Debentures shall, however, be a representation and warranty by the Trustee that the Debentures or interim Debentures have been Authenticated by or on behalf of the Trustee pursuant to the provisions of this Indenture.

(3)The Trustee shall Authenticate Uncertificated Debentures (whether upon original issuance, exchange, registration of transfer or otherwise) by completing its Internal Procedures and the Corporation shall, and hereby acknowledges that it shall, thereupon be deemed to have duly and validly issued such Uncertificated Debentures have been duly issued hereunder and that the holder or holders are entitled to the benefits of this Indenture. The register shall be final and conclusive evidence as to all matters relating to Uncertificated Debentures with respect to which this Indenture requires the Trustee to maintain records or accounts. In case of differences between the register at any time and any other time the register at the later time shall be controlling, absent manifest error and such Uncertificated Debentures are binding on the Corporation.

(4)The Trustee will Authenticate Debentures upon the Written Direction of the Corporation.

Section 2.9 Interim Debentures or Certificates

Pending the delivery of definitive Debentures of any series to the Trustee, the Corporation may issue and the Trustee Authenticate in lieu thereof interim Debentures in such forms and in such denominations and signed in such manner as provided herein, entitling the holders thereof to definitive Debentures of the series when the same are ready for delivery; or the Corporation may execute and the Trustee Authenticate a temporary Debenture for the whole principal amount of Debentures of the series then authorized to be issued hereunder and deliver the same to the Trustee and thereupon the Trustee may issue its own interim certificates in such form and in such amounts, not exceeding in the aggregate the principal amount of the temporary Debenture so delivered to it, as the Corporation and the Trustee may approve entitling the holders thereof to definitive Debentures of the series when the same are ready for delivery; and, when so issued and certified, such interim or temporary Debentures or interim certificates shall, for all purposes but without duplication, rank in respect of this Indenture equally with Debentures duly issued hereunder and, pending the exchange thereof for definitive Debentures, the holders of the interim or temporary Debentures or interim certificates shall be deemed without duplication to be Debentureholders and entitled to the benefit of this Indenture to the same extent and in the same manner as though the said exchange had actually been made. Forthwith after the Corporation shall have delivered the definitive Debentures to the Trustee, the Trustee shall cancel such temporary Debentures, if any, and shall call in for exchange all interim Debentures or certificates that shall have been issued and forthwith after such exchange shall cancel the same. No charge shall be made by the Corporation or the Trustee to the holders of such interim or temporary Debentures or interim certificates for the exchange thereof. All interest paid upon interim or temporary Debentures or interim certificates shall be noted thereon as a condition precedent to such payment unless paid by cheque to the registered holders thereof.

Section 2.10 Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue, and thereupon the Trustee shall Authenticate and deliver, a new Debenture upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in a form approved by the Trustee and shall be entitled to the benefits of this Indenture and rank equally in accordance with its terms with all other Debentures issued or to be issued hereunder. In case of loss, theft or destruction, the applicant for a substituted Debenture shall furnish to the Corporation and to the Trustee such evidence of the loss, theft or destruction of the Debenture as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

Section 2.11 Concerning Interest

(1)All Debentures issued hereunder, whether originally or upon exchange or in substitution for previously issued Debentures which are interest bearing, shall bear interest (i) from and including their issue date, or (ii) from and including the last Interest Payment Date to which interest shall have been paid or made available for payment on the outstanding Debentures of that series, whichever shall be the later, or, in respect of Debentures subject to a Periodic Offering, from and including their issue date or from and including the last Interest Payment Date to which interest shall have been paid or made available for payment on such Debentures, in all cases, to and excluding the next Interest Payment Date.

(2)Unless otherwise specifically provided in the terms of the Debentures of any series, interest shall be computed on the basis of a year of 360 days composed of twelve 30-day months. With respect to any series of Debentures, whenever interest is computed on the basis of a year (the “deemed year”) which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

Section 2.12 Ranking of Debentures

The Debentures will be direct unsecured obligations of the Corporation. Each Debenture of the same series of Debentures will rank pari passu with each other Debenture of the same series (regardless of their actual date or terms of issue) and, subject to statutory preferred exceptions, with all other previously existing and future unsecured indebtedness of the Corporation.

Section 2.13 Payments of Amounts Due on Maturity

Except as may otherwise be provided herein or in any supplemental indenture in respect of any series of Debentures, payments of amounts due upon maturity of the Debentures will be made in the following manner. The Corporation will cause the Trustee to establish and maintain with the Trustee a Maturity Account for each series of Debentures. Each such Maturity Account shall be maintained by and be subject to the control of the Trustee for the purposes of this Indenture. On or before 11:00 a.m. (Toronto time) not less than one Business Day immediately prior to each Maturity Date for Debentures outstanding from time to time under this Indenture, the Corporation will deliver to the Trustee a wire transfer for deposit in the applicable Maturity Account in an amount sufficient to pay the cash amount payable in respect of such Debentures (including the principal amount together with any accrued and unpaid interest thereon less

​

​

- 18 -

any tax required by law to be deducted). The Trustee, on behalf of the Corporation, will pay to each holder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture, upon surrender of the Debenture at any branch of the Trustee designated for such purpose from time to time by the Corporation and the Trustee. The delivery of such funds to the Trustee for deposit to the applicable Maturity Account will satisfy and discharge the liability of the Corporation for the Debentures to which the delivery of funds relates to the extent of the amount delivered (plus the amount of any tax deducted as aforesaid) and such Debentures will thereafter to that extent not be considered as outstanding under this Indenture and such holder will have no other right in regard thereto other than to receive out of the money so delivered or made available the amount to which it is entitled. Interest shall cease to accrue on the Debentures upon the Maturity Date provided the Trustee has received, by the Maturity Date, from the Corporation all the funds due and payable on the Debentures.

Section 2.14 Canadian Legend on the Debentures and Common Shares

The certificates or other instruments, including DRS advices, representing the Debentures, and the stock certificates, or DRS advices, representing any Common Shares issued upon conversion of such Debentures, (if issued prior to the expiration of the applicable hold periods), if any, will bear the following legend in accordance with Applicable Securities Legislation:

“UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [INSERT THE DATE THAT IS 4 MONTHS AND A DAY AFTER THE DISTRIBUTION DATE].”

(1)The Debentures and Common Shares issuable upon conversion thereof have not been and will not be registered under the U.S. Securities Act or any state securities laws. Debentures issued to a U.S. Debentureholder, and all Common Shares issuable on conversion thereof, shall be “restricted securities” within the meaning of Rule 144(a)(3) under the U.S. Securities Act. Such Debentures and Common Shares, as well as all securities issued in exchange for or in substitution of such Debentures and Common Shares, shall be issued as individual physical certificates and, until such time as the same is no longer required under applicable requirements of the U.S. Securities Act or state securities laws, shall bear the following legend (the “U.S. Legend”):

“THE SECURITIES REPRESENTED HEREBY [and if a Debenture, the following shall be added: AND THE SECURITIES ISSUABLE UPON CONVERSION HEREOF] HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING THESE SECURITIES, AGREES FOR THE BENEFIT OF THE LIMESTONE BOAT COMPANY LIMITED (THE “CORPORATION”) THAT THESE SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE CANADIAN LAWS AND REGULATIONS, (C) IN ACCORDANCE WITH RULE 144 UNDER THE U.S. SECURITIES ACT, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, PROVIDED THAT IN THE CASE OF TRANSFERS PURSUANT TO (C) OR (D) ABOVE,

​

​

​

- 19 -

A LEGAL OPINION REASONABLY SATISFACTORY TO THE CORPORATION MUST FIRST BE PROVIDED TO THE TRANSFER AGENT. THESE SECURITIES MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON CANADIAN STOCK EXCHANGES.”

provided that, if any such Debentures or Common Shares are being transferred in compliance with Rule 904 of Regulation S, the legend may be removed by providing to the Trustee or registrar and transfer agent, as applicable: (i) a declaration in the form set forth as Schedule D hereto (or in such form as the Corporation may prescribe from time to time), and/or (ii) if required by the Corporation, an opinion of counsel, of recognized standing reasonably satisfactory to the Corporation, or other evidence reasonably satisfactory to the Corporation, that the proposed transfer may be effected without registration under the

U.S. Securities Act;

and provided, further, that, if any such Debentures or Common Shares are being sold pursuant to Rule 144 under the U.S. Securities Act, the legend may be removed by delivering to the Trustee or the registrar and transfer agent, as applicable, an opinion of counsel of recognized standing reasonably satisfactory to the Corporation, that the legend is no longer required under applicable requirements of the

U.S. Securities Act or state securities laws.

(2)Prior to the issuance of the Debentures, the Corporation shall notify the Trustee, in writing, concerning which Debentures are to be issued as Restricted Physical Debentures which shall bear the U.S. Legend. The Trustee will thereafter maintain a list of all registered holders from time to time of such Restricted Physical Debentures.

Section 2.16 Payment of Interest

amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Corporation may make payment of such interest or make such interest available for payment in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above.

Section 3.1 Fully Registered Debentures

(1)With respect to each series of Debentures issuable as Fully Registered Debentures, the Corporation shall cause to be kept by and at the principal office of the Trustee in Toronto, Ontario and by the Trustee or such other registrar as the Corporation, with the approval of the Trustee, may appoint at such other place or places, if any, as may be specified in the Debentures of such series or as the Corporation may designate with the approval of the Trustee, a register in which shall be entered the names and addresses of the holders of Fully Registered Debentures and particulars of the Debentures held by them respectively and of all transfers of Fully Registered Debentures.

Upon surrender for registration of transfer of Debentures, the Corporation shall issue and thereupon the Trustee shall Authenticate and deliver a new Debenture Certificate or DRS advice of like tenor in the name of the designated transferee and register such transfer in accordance with Section 3.1.

(2)In case of a circumstance constituting a default or Event of Default with respect to any Senior Indebtedness, and during the continuance thereof, or upon the acceleration of the maturity of any Senior Indebtedness unless and until such default or Event of Default shall have been cured or waived or shall have ceased to exist or such acceleration has been rescinded or when a payment could reasonably be expected to cause a default or Event of Default under any Senior Indebtedness, no payment (by purchase of Debentures, subject to Section 5.13 conversion, repayment in shares or otherwise) shall be made by the Corporation (except as provided in Section 5.8) with respect to the Debenture Liabilities and neither the Trustee nor the Debentureholders shall be entitled to demand, accelerate, institute proceedings for the collection of (which shall, for certainty include proceedings related to an adjudication or declaration as to the insolvency or bankruptcy of the Corporation and other similar creditor proceedings), or receive any payment or benefit (including without limitation by set-off, combination of accounts or otherwise in any manner whatsoever) on account of the Debentures after the happening of such a default or Event of Default or acceleration (except as provided in Section 5.8), and unless and until such default or Event of Default shall have been cured or waived or shall have ceased to exist or such acceleration has been rescinded, such payments shall be held in trust for the benefit of, and, if and when such Senior Indebtedness shall have become due and payable, shall be paid over to, the holders of the Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing an amount of the Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; provided, however, that the foregoing shall in no way prohibit, restrict or prevent the Trustee from taking such actions as may be necessary to preserve claims of the Trustee and/or the holders of the Debentures under this Indenture in any bankruptcy, reorganization or insolvency proceeding (including, without limitation, the filing of proofs of claim in any such bankruptcy, reorganization or insolvency proceedings by or against the Corporation or its Subsidiaries and exercising its rights to vote as an unsecured

creditor under any such bankruptcy, reorganization or insolvency proceedings commenced by or against the Corporation or its Subsidiaries).

(3)The fact that any payment hereunder is prohibited by this Section 5.5 shall not prevent the failure to make such payment from being an Event of Default hereunder.

Section 5.6 Payment on Debentures Permitted

Nothing contained in this Article 5 or elsewhere in this Indenture, or in any of the Debentures, shall affect the obligation of the Corporation to make, or prevent the Corporation from making, where it is otherwise permitted to do so, at any time except as prohibited by Section 5.2 or Section 5.5 any payment of principal of or interest on the Debentures. The fact that any such payment is prohibited by Section 5.2 or Section 5.5 shall not prevent the failure to make such payment from being an Event of Default hereunder. Nothing contained in this Article 5, elsewhere in this Indenture or in any of the Debentures other than in the case of a continuing default or Event of Default under Senior Indebtedness or acceleration of Senior Indebtedness that has not been rescinded or where a payment could reasonably be expected to cause a default or Event of Default under any Senior Indebtedness, in which case and Section 5.13 shall govern, shall prevent the conversion of the Debentures or, except as prohibited by Section 5.2, Section 5.5 or Section 5.13, the application by the Trustee of any monies deposited with the Trustee hereunder for the purpose, to the payment of or on account of the Debenture Liabilities.

Section 5.7 Confirmation of Subordination

Each Debentureholder by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effect the subordination as provided in this Article 5 and appoints the Trustee his attorney-in-fact for any and all such purposes. This power of attorney, being coupled with an interest and rights, shall be irrevocable. Upon request of the Corporation, and upon being furnished an Officer’s Certificate stating that one or more named persons are Senior Creditors and specifying the amount and nature of the Senior Indebtedness of such Senior Creditor, the Trustee shall enter into a written agreement or agreements with the Corporation and the person or persons named in such Officer’s Certificate providing that such person or persons are entitled to all the rights and benefits of this Article 5 as a Senior Creditor and for such other matters, such as an agreement not to amend the provisions of this Article 5 and the definitions herein, which prejudice the rights of the holders of Senior Indebtedness under this Article 5 without the consent of such Senior Creditor, or their representative or the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued as the Senior Creditor may reasonably request. Such agreement shall be conclusive evidence that the indebtedness specified therein is Senior Indebtedness, however, nothing herein shall impair the rights of any Senior Creditor who has not entered into such an agreement.

Section 5.8 Knowledge of Trustee

Notwithstanding the provisions of this Article 5 or any provision in this Indenture or in the Debentures contained, the Trustee will not be charged with knowledge of any Senior Indebtedness or of any default in the payment thereof, or of the existence of any Event of Default or any other fact that would prohibit the making of any payment of monies to or by the Trustee, or the taking of any other action by the Trustee, unless and until the Trustee has received written notice thereof from the Corporation, any Debentureholder or any Senior Creditor or a trustee on behalf of any one or more Senior Creditors, and such notice to the Trustee shall be deemed to be notice to holders of the Debentures. The Trustee will notify Debentureholders as soon as reasonably practicable of such notice.

Section 5.9 Trustee May Hold Senior Indebtedness

The Trustee is entitled to all the rights set forth in this Article 5 with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture deprives the Trustee of any of its rights as such holder.

Section 5.10 Rights of Holders of Senior Indebtedness Not Impaired

No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein will at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Corporation or by any non-compliance by the Corporation with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

Section 5.11 Altering the Senior Indebtedness

The holders of the Senior Indebtedness have the right to extend, renew, modify or amend the terms of the Senior Indebtedness or any security therefor and to release, sell or exchange such security and otherwise to deal freely with the Corporation, all without notice to or consent of the Debentureholders or the Trustee and without affecting the liabilities and obligations of the parties to this Indenture or the Debentureholders.

Section 5.12 Additional Indebtedness

Section 5.13 Right of Debentureholder to Convert Not Impaired

The subordination of the Debentures to the Senior Indebtedness and the provisions of this Article 5 do not impair in any way the right of a Debentureholder to convert its Debentures pursuant to Article 6 provided that on such conversion any payment of cash in lieu of fractional shares will not be made. In addition, if a continuing default or Event of Default under Senior Indebtedness or acceleration of Senior Indebtedness that has not been rescinded has occurred then a Debentureholder shall only be entitled to convert its Debentures to the extent that it will receive, on conversion, equity in the Corporation.

Section 5.14 Invalidated Payments

In the event that any of the Senior Indebtedness shall be paid in full and subsequently, for whatever reason, such formerly paid or satisfied Senior Indebtedness becomes unpaid or unsatisfied, the terms and conditions of this Article 5 shall be reinstated and the provisions of this Article shall again be operative until all Senior Indebtedness is repaid in full, provided that such reinstatement shall not give the Senior Creditors any rights or recourses against the Trustee or the Debentureholders for amounts paid to the Debentureholders subsequent to such payment or satisfaction in full and prior to such reinstatement.

Section 5.15 Contesting Security

Section 6.3 Manner of Exercise of Right to Convert

(1)The holder of a Debenture Certificate or DRS advice desiring to convert such Debenture in whole or in part into Common Shares shall surrender such Debenture Certificate or DRS advice to the Trustee at its principal office in the City of Toronto, Ontario together with the conversion notice in the form of Schedule B or any other written notice in a form satisfactory to the Trustee, duly executed by the holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee, exercising his right to convert such Debenture in accordance with the provisions of this Article; provided that with respect to an Uncertificated Debenture held in CDS, registration and surrender of interests in the Debentures will be made only through the Depository’s non-certificated system. Upon the Trustee receiving an executed conversion notice as set out in Schedule B with the box therein being ticked, the Trustee will cause the issuance of the Common Shares without the United States legend. Thereupon such Debentureholder or, subject to compliance with the applicable terms and provisions hereof and payment of all applicable stamp or security transfer taxes or other governmental charges and compliance with all reasonable requirements of the Trustee, his nominee(s) or assignee(s) shall be entitled to be entered in the books of the Corporation as at the Date of Conversion (or such later date as is specified in Section 6.3(2)) as the holder of the number of Common Shares, as applicable, into which such Debenture is convertible in accordance with the provisions of this Article and, as soon as practicable thereafter, the Corporation shall deliver to such Debentureholder or, subject as aforesaid, his nominee(s) or assignee(s), a certificate, certificates, or DRS advice for such Common Shares or cause the deposit such Common Shares through the Depository’s non- certificated system and make or cause to be made any payment of interest to which such holder is entitled in accordance with Section 6.3(5).

(2)For the purposes of this Article, a Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered when the register of the Trustee is open and in accordance with the provisions of this Article or, in the case of an Uncertificated Debenture held in CDS which the Trustee received notice of and all necessary documentation in respect of the exercise of the conversion rights and, in the case of a Debenture so surrendered by mail or other means of transmission, on the date on which it is received by the Trustee at one of its offices specified in Section 6.3(1); provided that if a Debenture is surrendered for conversion on a day on which the register of Common Shares is closed, the Person or Persons entitled to receive Common Shares shall become the holder or holders of record of such Common Shares as at the date on which such registers are next reopened.

(3)Any part, being $1,000 or an integral multiple thereof, of a Debenture in a denomination in excess of $1,000 may be converted as provided in this Article and all references in this Indenture to conversion of Debentures shall be deemed to include conversion of such parts.

(4)The holder of any Debenture of which only a part is converted shall, upon the exercise of his right of conversion surrender such Debenture to the Trustee in accordance with Section 6.3(1), and the Trustee shall cancel the same and shall without charge forthwith Authenticate and deliver to the holder a new Debenture or Debentures in an aggregate principal amount equal to the unconverted part of the principal amount of the Debenture so surrendered or, with respect to an Uncertificated Debenture held in CDS, registration and surrender of interests in the Debentures will be made only through the Depository’s non-certificated system.

interest on conversion of Debentures of any series) to receive accrued and unpaid interest in respect thereof, in cash, up to but excluding the Date of Conversion and the Common Shares issued upon such conversion shall rank only in respect of distributions or dividends declared in favour of shareholders of record on and after the Date of Conversion or such later date as such holder shall become the holder of record of such Common Shares pursuant to Section 6.3(2), from which applicable date they will for all purposes be and be deemed to be issued and outstanding as fully paid and non-assessable Common Shares.

Section 6.4 Adjustment of Conversion Price

The Conversion Price in effect at any date shall be subject to adjustment from time to time as set forth below.

the Conversion Price in effect on the effective date of such subdivision, redivision, reduction, combination or consolidation or on the record date for such issue of Common Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, redivision or dividend, or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number of outstanding Common Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this Section 6.4(a) shall occur. Any such issue of Common Shares by way of a dividend or distribution shall be deemed to have been made on the record date for the dividend or distribution for the purpose of calculating the number of outstanding Common Shares under subsections (c) and (d) of this Section 6.4.

give effect to or to evidence the provisions of this Section 6.4(d), the Corporation, its successor, or such purchasing Person or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the holder of Debentures to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any cash, shares or other securities or property to which a holder of Debentures is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Trustee pursuant to the provisions of this Section 6.4(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 15. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing Person or other entity and the Trustee shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 6.4(d) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, share exchanges, acquisitions, combinations, sales or conveyances.

such holder would have received had such holder converted each Debenture on such record date. If the Board of Directors determines the fair market value of any distribution for purposes of this clause (e) of Section 6.4 by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Shares.

Notwithstanding the foregoing, if the securities distributed by the Corporation to all holders of its Common Shares consist of capital stock of, or similar equity interests in, a Subsidiary or other business of the Corporation (the “Spinoff Securities”), the Conversion Price shall be adjusted, unless the Corporation makes an equivalent distribution to the holders of Debentures, so that the same shall be equal to the rate determined by multiplying the Conversion Price in effect on the record date fixed for the determination of shareholders entitled to receive such distribution by a fraction, the denominator of which shall be the sum of (A) the weighted average trading price of one   Common   Share over   the 20 consecutive trading day period (the “Spinoff Valuation Period”) commencing on and including the fifth trading day after the date on which ex-dividend trading commences for such distribution on the TSXV (or such other exchange on which the Common Shares are then listed) and (B) the product of (i) the weighted average trading price (calculated in substantially the same way as the Current Market Price is calculated for the Common Shares) over the Spinoff Valuation Period of the Spinoff Securities or, if no such prices are available, the fair market value of the Spinoff Securities as reasonably determined by the Board of Directors (which determination shall be conclusive and shall be evidenced by an Officer’s Certificate delivered to the Trustee) multiplied by (ii) the number of Spinoff Securities distributed in respect of one Common Share and the numerator of which shall be the weighted average trading price of one Common Share over the Spinoff Valuation Period, such adjustment to become effective immediately preceding the opening of business on the 25th trading day after the date on which ex-dividend trading commences; provided, however, that the Corporation may in lieu of the foregoing adjustment elect to make adequate provision so that each holder of Debentures shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such holder of Debentures would have received if such Debentures had been converted on the record date with respect to such distribution.

​

​

Shares outstanding (less any Purchased Common Shares and excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time and the Current Market Price on the Expiration Date and (ii) the numerator of which shall be the product of the number of Common Shares outstanding (including Purchased Common Shares but excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time multiplied by the Current Market Price on the Expiration Date, such increase to become effective immediately preceding the opening of business on the day following the Expiration Date. In the event that the Corporation is obligated to purchase Common Shares pursuant to any such issuer bid, but the Corporation is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have been in effect based upon the number of Common Shares actually purchased, if any. If the application of this clause (f) of Section 6.4 to any issuer bid would result in a decrease in the Conversion Price, no adjustment shall be made for such issuer bid under this clause (f).

For purposes of this Section 6.4(f), the term “issuer bid” shall mean an issuer bid under Applicable Securities Legislation or a take-over bid under Applicable Securities Legislation by a Subsidiary of the Corporation for the Common Shares and all references to “purchases” of Common Shares in issuer bids (and all similar references) shall mean and include the purchase of Common Shares in issuer bids and all references to “tendered Common Shares” (and all similar references) shall mean and include Common Shares tendered in issuer bids.

in the event holders of not less than 25% of the principal amount of the Debentures then outstanding notify the Trustee that they do not agree with such determination within 14 days of such determination being communicated to all the holders, such determination shall be made by a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustee (who may be the Auditors of the Corporation); such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation, the Trustee, and the Debentureholders. In the absence of notice by holders of not less than 25% of the principal amount of the Debentures then outstanding of their disagreement as aforesaid, the determination of the Board of Directors shall be binding.

Section 6.5 No Requirement to Issue Fractional Common Shares

The Corporation shall not be required to issue fractional Common Shares upon the conversion of Debentures pursuant to this Article. If more than one Debenture shall be surrendered for conversion at one

​

​

- 37 -

time by the same holder, the number of whole Common Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted. If any fractional interest in a Common Share would, except for the provisions of this Section, be deliverable upon the conversion of any principal amount of Debentures, the number of Common Shares so issuable shall be rounded down to the nearest whole number. No compensation will be paid for the remainder balance as a result of such rounding.

Section 6.6 Forced Conversion

Notwithstanding anything to the contrary contained herein and subject to any required regulatory approval, if, at any time beginning on September 14, 2021, the VWAP of the Common Shares on the TSXV (or such other recognized stock exchange on which the Common Shares are listed for trading) for 20 consecutive trading days equals or exceeds $0.50, as adjusted in accordance with Section 6.4, the Corporation may force conversion of all but not less than all of the principal amount and all accrued and unpaid interest (less any tax required by law to be deducted or withheld) of the Debentures at the then applicable Conversion Price, upon giving the Debentureholders and the Trustee not less than 30 days advance written notice, in accordance with Section 13.2. The Corporation shall also provide an Officer’s Certificate to the Trustee certifying that the conditions have been met in order trigger such forced conversion, including the relevant calculations.

Section 6.7 Corporation to Reserve Common Shares

The Corporation covenants with the Trustee that it will at all times reserve and keep available out of its authorized Common Shares (if the number thereof is or becomes limited), solely for the purpose of issue upon conversion of Debentures as in this Article provided, and conditionally allot to Debentureholders who may exercise their conversion rights hereunder, such number of Common Shares as shall then be issuable upon the conversion of all outstanding Debentures. The Corporation covenants with the Trustee that all Common Shares which shall be so issuable shall be duly and validly issued as fully-paid and non- assessable.

Section 6.8 Cancellation of Converted Debentures

Subject to the provisions of Section 6.3 as to Debentures converted in part, all Debentures converted in whole or in part under the provisions of this Article shall be forthwith delivered to and cancelled by the Trustee and no Debenture shall be issued in substitution for those converted.

Section 6.9 Certificate as to Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 6.4, deliver an Officer’s Certificate to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall, if required by the Trustee, be verified by advice of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustee (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest. When so approved, the Corporation shall forthwith give notice to the Debentureholders in the manner provided in Section 13.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price.

Such notice shall be given not less than 14 days in each case prior to such applicable record date.

(2)In addition, the Corporation covenants with the Trustee that so long as any Debenture remains outstanding, it will give notice to the Trustee, and to the Debentureholders in the manner provided in Section 13.2, at least 30 days prior to the (i) effective date of any transaction referred to in Section 6.4(d) stating the consideration into which the Debentures will be convertible after the effective date of such transaction, and (ii) Expiration Date of any transaction referred to in Section 6.4(f) stating the consideration paid per Common Share in such transaction.

If the Corporation shall fail to perform any of its covenants contained in this Indenture, the Trustee may notify the Debentureholders of such failure on the part of the Corporation or may itself perform any of the covenants capable of being performed by it, but shall be under no obligation to do so or to notify the Debentureholders.

There is no obligation on the Corporation to gross-up or pay additional amounts to a holder of Debentures in respect of such deductions or withholdings. For greater certainty, if any amount is required to be deducted or withheld in respect of Withholding Taxes upon a conversion of a Debenture, the Corporation shall be entitled to liquidate such number of Common Shares (or other securities) issuable as a result of such conversion as shall be necessary in order to satisfy such requirement. The Corporation shall provide the Trustee with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of any forms received from such government authority or agency promptly after receipt thereof.

ARTICLE 8 – DEFAULT

Section 8.1 Events of Default

(1)Each of the following events constitutes, and is herein sometimes referred to as, an “Event of Default”:

​

​

- 42 -

proceedings against it under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws, or consents 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 Corporation or any Material Subsidiary or makes a general assignment for the benefit of creditors, or admits in writing its inability to pay its debts generally as they become due;

then: (i) in each and every such event listed above, the Trustee may, in its discretion, but subject to the provisions of this section, and shall, upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures then outstanding (or if the Event of Default shall exist only in respect of one or more series of the Debentures then outstanding, then upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures of such series then outstanding), subject to the provisions of Section 8.3, by notice in writing to the Corporation declare the principal of and interest and premium, if any, on all Debentures then outstanding and all other monies outstanding hereunder to be due and payable and the same shall thereupon forthwith become immediately due and payable (or, if the Event of Default shall exist only in respect of one or more series of the Debentures then outstanding, then the Trustee may declare due and payable the principal and interest and premium, if any, only with respect to such Debentures in respect of which there is an Event of Default) to the Trustee, and (ii) on the occurrence of an Event of Default under Sections 8.1(1)(e), 8.1(1)(f) or 8.1(1)(g), the principal of and interest and premium, if any, on all Debentures then outstanding hereunder and all other monies outstanding hereunder, shall automatically without any declaration or other act on the part of the Trustee or any Debentureholder become immediately due and payable to the Trustee and, in either case, upon such amounts becoming due and payable in either (i) or (ii) above, the Corporation shall forthwith pay to the Trustee for the benefit of the Debentureholders such principal, accrued and unpaid interest and premium, if any, and interest on amounts in default on such Debenture and all other monies outstanding hereunder, together with subsequent interest at the rate borne by the Debentures on such principal, interest, premium and such other monies from the date of such declaration or event until payment is received by the Trustee, such subsequent interest to be payable at the times and places and in the manner mentioned in and according to the tenor of the Debentures. Such payment when made shall be deemed to have been made in discharge of the Corporation’s obligations hereunder and any monies so received by the Trustee shall be applied in the manner provided in Section 8.6.

(2)For greater certainty, for the purposes of this Section 8.1, a series of Debentures shall be in default in respect of an Event of Default if such Event of Default relates to a default in the payment of principal, premium, if any, or interest on the Debentures of such series in which case references to Debentures in this Section 8.1 refer to Debentures of that particular series.

(3)For purposes of this Article 8, where the Event of Default refers to an Event of Default with respect to a particular series of Debentures as described in this Section 8.1, then this Article 8 shall apply mutatis mutandis to the Debentures of such series and references in this Article 8 to the Debentures shall mean Debentures of the particular series and references to the Debentureholders shall refer to the Debentureholders of the particular series, as applicable.

(3)The Trustee shall also have the power at any time and from time to time to institute and to maintain such suits and proceedings as it may be advised shall be necessary or advisable to preserve and protect its interests and the interests of the Debentureholders.

(4)All rights of action hereunder may be enforced by the Trustee without the possession of any of the Debentures or the production thereof on the trial or other proceedings relating thereto.

Section 8.5 No Suits by Debentureholders

(2)The Trustee shall not be bound to apply or make any partial or interim payment of any monies coming into its hands if the amount so received by it, after reserving thereout such amount as the Trustee may think necessary to provide for the payments mentioned in Section 8.6(1)(a), is insufficient to make a distribution of at least 2% of the aggregate principal amount of the outstanding Debentures, but it may retain the money so received by it and invest or deposit the same as provided in Section 14.9 until the money or the investments representing the same, with the income derived therefrom, together with any other monies for the time being under its control shall be sufficient for the said purpose or until it shall

Section 8.9 Remedies Cumulative

No remedy herein conferred upon or reserved to the Trustee, or upon or to the holders of Debentures 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.

Some person, who need not be a Debentureholder, nominated in writing by the Corporation (in case it convenes the meeting) or by the Trustee (in any other case) shall be chairman of the meeting and if no person is so nominated, or if the person so nominated is not present within 15 minutes from the time fixed for the holding of the meeting, a majority of the Debentureholders present in person or by proxy shall choose some person present to be chairman.

Section 12.4 Quorum

Subject to the provisions of Section 12.12, at any meeting of the Debentureholders a quorum shall consist of Debentureholders present in person or by proxy and representing at least 25% in principal amount of the outstanding Debentures and, if the meeting is a Serial Meeting, at least 25% of the Debentures then outstanding of each especially affected series. If a quorum of the Debentureholders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if summoned by the Debentureholders or pursuant to a request of the Debentureholders, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place to the extent possible and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Debentureholders present in person or by proxy represented at such meeting shall form a quorum and may transact the business for which the meeting was originally convened. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum is present at the commencement of business.

such meeting and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

Section 12.6 Show of Hands

Every question submitted to a meeting shall, subject to Section 12.7, be decided in the first place by a majority of the votes given on a show of hands except that votes on Extraordinary Resolutions shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Debentures, if any, held by him.

Section 12.7 Poll

On every Extraordinary Resolution, and on any other question submitted to a meeting when demanded by the chairman or by one or more Debentureholders or proxies for Debentureholders, a poll shall be taken in such manner and either at once or after an adjournment as the chairman shall direct. Questions other than Extraordinary Resolutions shall, if a poll be taken, be decided by the votes of the holders of a majority in principal amount of the Debentures and of each especially affected series, if applicable, represented at the meeting and voted on the poll.

Section 12.8 Voting

On a show of hands every person who is present and entitled to vote, whether as a Debentureholder or as proxy for one or more Debentureholders or both, shall have one vote. On a poll each Debentureholder present in person or represented by a proxy duly appointed by an instrument in writing shall be entitled to one vote in respect of each $1,000 principal amount of Debentures of which he shall then be the holder. In the case of any Debenture denominated in a currency or currency unit other than Canadian dollars, the principal amount thereof for these purposes shall be computed in Canadian dollars on the basis of the conversion of the principal amount thereof at the applicable spot buying rate of exchange for such other currency or currency unit as reported by the Bank of Canada at the close of business on the Business Day next preceding the meeting. Any fractional amounts resulting from such conversion shall be rounded to the nearest $100. A proxy need not be a Debentureholder. In the case of joint holders of a Debenture, any one of them present in person or by proxy at the meeting may vote in the absence of the other or others but in case more than one of them be present in person or by proxy, they shall vote together in respect of the Debentures of which they are joint holders.

Section 12.9 Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Corporation (in case it convenes the meeting) or the Trustee (in any other case) for the purpose of enabling the Debentureholders to be present and vote at any meeting without producing their Debentures, and of enabling them to be present and vote at any such meeting by proxy and of lodging instruments appointing such proxies at some place other than the place where the meeting is to be held, may from time to time make and vary such regulations as it shall think fit providing for and governing any or all of the following matters:

​

​

​

- 57 -

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as the holders of any Debentures, or as entitled to vote or be present at the meeting in respect thereof, shall be Debentureholders and persons whom Debentureholders have by instrument in writing duly appointed as their proxies.

Section 12.10 Persons Entitled to Attend Meetings

The Corporation and the Trustee, by their respective officers and directors, the Auditors of the Corporation and the legal advisors of the Corporation, the Trustee or any Debentureholder may attend any meeting of the Debentureholders, but shall have no vote as such.

Section 12.14 Minutes

Minutes of all resolutions and proceedings at every meeting as aforesaid shall be made and duly entered in books to be from time to time provided for that purpose by the Trustee at the expense of the Corporation, and any such minutes as aforesaid, if signed by the chairman of the meeting at which such resolutions were passed or proceedings had, or by the chairman of the next succeeding meeting of the Debentureholders, shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting, in respect of the proceedings of which minutes shall have been made, shall be deemed to have been duly held and convened, and all resolutions passed thereat or proceedings taken thereat to have been duly passed and taken.

Section 12.18 Concerning Serial Meetings

If in the opinion of Counsel any business to be transacted at any meeting, or any action to be taken or power to be exercised by instrument in writing under Section 12.15, does not adversely affect the rights of the holders of Debentures of one or more series, the provisions of this Article 12 shall apply as if the Debentures of such series were not outstanding and no notice of any such meeting need be given to the holders of Debentures of such series. Without limiting the generality of the foregoing, a proposal to modify or terminate any covenant or agreement which is effective only so long as Debentures of a particular series are outstanding shall be deemed not to adversely affect the rights of the holders of Debentures of any other series.

ARTICLE 14 – CONCERNING THE TRUSTEE

Section 14.1 No Conflict of Interest

The Trustee represents to the Corporation that, to the best of its knowledge, at the date of execution and delivery by it of this Indenture, there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder. Notwithstanding the provisions of this Section 14.1, if such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture, and the Debentures issued hereunder, shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises but the Trustee shall, within 90 days after ascertaining that it has a material conflict of interest, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Section 14.2.

Section 14.2 Replacement of Trustee

(1)The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation 90 days’ notice in writing or such shorter notice as the Corporation may accept as sufficient. In the event of the Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Debentureholders. Failing such appointment by the Corporation, the retiring Trustee or any Debentureholder may apply to a Judge of the Ontario Superior Court of Justice, on such notice as such Judge may direct at the Corporation’s expense, for the appointment of a new Trustee but any new Trustee so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Debentureholders and the appointment of such new Trustee shall be effective only upon such new Trustee becoming bound by this Indenture. Any new Trustee appointed under any provision of this Section 14.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces of Canada. On any new appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee.

(2)Any company into which the Trustee may be merged or, with or to which it may be consolidated, amalgamated or sold, or any company resulting from any merger, consolidation, sale or amalgamation to which the Trustee shall be a party, or any company which shall purchase all or substantially all of the corporate trust book of business of the Trustee, shall be the successor trustee under this Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Trustee or of the Corporation, the Trustee ceasing to act, upon payment of its reasonable fees and expenses, shall execute and deliver an instrument assigning and transferring to such successor Trustee, upon the trusts herein expressed, all the rights, powers and trusts of the Trustee so ceasing to act, and, shall duly assign, transfer and deliver all property and money held by such Trustee to the successor Trustee so appointed in its place. Should any deed, conveyance or instrument in writing from the Corporation be required by any new Trustee for more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and instruments in writing shall on request of said new Trustee, be made, executed, acknowledged and delivered by the Corporation.

Section 14.5 Evidence and Authority to Trustee, Opinions, etc.

(1)The Corporation shall furnish to the Trustee evidence of compliance with the conditions precedent provided for in this Indenture relating to any action or step required or permitted to be taken by the Corporation or the Trustee under this Indenture or as a result of any obligation imposed under this Indenture, including without limitation, the Authentication and delivery of Debentures hereunder, the satisfaction and discharge of this Indenture and the taking of any other action to be taken by the Trustee at the request of or on the application of the Corporation, forthwith if and when (a) such evidence is required by any other Section of this Indenture to be furnished to the Trustee in accordance with the terms of this Section 14.5, or (b) the Trustee, in the exercise of its rights and duties under this Indenture, gives the Corporation written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

(5)The Corporation shall furnish or cause to be furnished to the Trustee at any time if the Trustee reasonably so requires, its certificate that the Corporation has complied with all covenants, conditions or other requirements contained in this Indenture, the non-compliance with which would, with the giving of notice or the lapse of time, or both, or otherwise, constitute an Event of Default, or if such is not the case, specifying the covenant, condition or other requirement which has not been complied with and giving particulars of such non-compliance. The Corporation shall, whenever the Trustee so requires, furnish the Trustee with evidence by way of statutory declaration, opinion, report or certificate as specified by the Trustee as to any action or step required or permitted to be taken by the Corporation or as a result of any obligation imposed by this Indenture.

(6)Proof of the execution of an instrument in writing, including a request by any Debentureholder, may be made by the certificate of a notary, solicitor or commissioner for oaths, or other officer with similar powers, that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Trustee may consider adequate and in respect of a corporate Debentureholder, shall include a certificate of incumbency of such Debentureholder together with a certified resolution authorizing the person who signs such instrument to sign such instrument.

THE LIMESTONE BOAT COMPANY LIMITED

(A corporation incorporated under the laws of the Province of Ontario) 10.0% SUBORDINATED UNSECURED CONVERTIBLE DEBENTURE DUE MAY 14, 2024

The Limestone Boat Company Limited (the “Corporation”) for value received hereby acknowledges itself indebted and, subject to the provisions of the Debenture Indenture (the “Indenture”) dated as of May 14, 2021 between the Corporation and TSX Trust Company (the “Trustee”), promises to pay to                                                        , the registered holder hereof on May 14, 2024 or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture (any such date, the “Maturity Date”) the principal sum of • Dollars ($•) in lawful money of Canada on presentation and surrender of this Initial Debenture at the main branch of the Trustee in Toronto, Ontario in accordance with the terms of the Indenture and, subject as hereinafter provided, to pay interest on the principal amount hereof from, and including, the date hereof, or from the last Interest Payment Date to which interest shall have been paid or made available for payment hereon, whichever is later, at the rate of 10.0% per annum (based on a year of 360 days comprised of twelve 30-day months), in like money, in arrears in equal (with

​

​

​

​

​

the exception of the first interest payment which will include interest from May 14, 2021 as set forth below) annual instalments (less any tax required by law to be deducted) on December 31 in each year commencing on December 31, 2021 and the last payment (representing interest payable from the last Interest Payment Date to, but excluding, the Maturity Date) to fall due on the Maturity Date and, should the Corporation at any time make default in the payment of any principal, premium, if any, or interest, to pay interest on the amount in default at the same rate, in like money and on the same dates. For certainty, the first interest payment will include interest accrued from May 14, 2021 to December 31, 2021, which will be equal to $37.22 for each $1,000 principal amount of the Initial Debentures.

This Initial Debenture is one of the 10.0% Subordinated Unsecured Convertible Debentures (referred to herein as the “Initial Debentures”) of the Corporation issued or issuable in one or more series under the provisions of the Indenture. The Initial Debentures authorized for issue immediately are limited to an aggregate principal amount of $17,000,000 in lawful money of Canada, in connection with the non- brokered private placement of the Initial Debentures. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Initial Debentures are to be issued and held and the rights and remedies of the holders of the Initial Debentures and of the Corporation and of the Trustee, all to the same effect as if the provisions of the Indenture were herein set forth to all of which provisions the holder of this Initial Debenture by acceptance hereof assents.

The Initial Debentures are issuable only in denominations of $1,000 and integral multiples thereof. Upon compliance with the provisions of the Indenture, Debentures of any denomination may be exchanged for an equal aggregate principal amount of Debentures in any other authorized denomination or denominations.

Any part, being $1,000 or an integral multiple thereof, of the principal of this Initial Debenture, provided that the principal amount of this Initial Debenture is in a denomination in excess of $1,000, is convertible, at the option of the holder hereof, upon surrender of this Initial Debenture at the principal office of the Trustee in ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇, at any time prior to the close of business on the fifth Business Day immediately preceding the Maturity Date, into common shares of the Corporation (the “Common Shares”) (without adjustment for interest accrued hereon or for dividends or distributions on Common Shares issuable upon conversion) at a conversion price of $0.36 (the “Conversion Price”) per Common Share, being a rate of approximately 2,777 Common Shares for each $1,000 principal amount of Initial Debentures, all subject to the terms and conditions and in the manner set forth in the Indenture. No Initial Debentures may be converted during the five Business Days preceding December 31 in each year, commencing December 31, 2021, as the registers of the Trustee will be closed during such periods. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Common Shares will be issued on any conversion, and any Common Shares so issuable will be rounded down to the nearest whole number. Holders converting their Debentures will receive accrued and unpaid interest thereon. If a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the person or persons entitled to receive Common Shares in respect of the Debentures so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date and, for clarity, any interest payable on such Debentures will be for the account of the holder of record of such Debentures at the close of business on the relevant record date.

Subject to the provisions in the Indenture and without further action on the part of the Debentureholder, if at any time beginning September 14 and prior to the Maturity Date, the volume weighted average price of the Common Shares on the Canadian Securities Exchange (or such other recognized stock exchange on which the Common Shares are listed for trading) for 20 consecutive trading days equals or exceeds $0.50, as adjusted in accordance with the Indenture, the Corporation may deliver a written notice to the Debentureholder to cause the Debentureholder to convert all but not less than the principal amount of the Debentures and all accrued and unpaid interest (less any tax required by law to be deducted or withheld) into that number of Common Shares of the Corporation equal to the principal amount of the Debentures

​

​

​

A-2

​

plus all accrued and unpaid interest (less any tax required by law to be deducted or withheld) to the date of such forced conversion.

The indebtedness evidenced by this Initial Debenture, and by all other Initial Debentures now or hereafter Authenticated and delivered under the Indenture, is a direct unsecured obligation of the Corporation.

The Indenture contains provisions making binding upon all holders of Initial Debentures outstanding thereunder (or in certain circumstances specific series of Initial Debentures) resolutions passed at meetings of such holders held in accordance with such provisions and instruments signed by the holders of a specified majority of Initial Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Initial Debenture or the Indenture.

The Indenture contains provisions disclaiming any personal liability on the part of holders of Common Shares and officers, directors and employees of the Corporation in respect of any obligation or claim arising out of the Indenture or this Initial Debenture.

This Initial Debenture may be signed by the manual or electronic signature of an authorized officer of the Corporation and if signed electronically shall be binding on the Corporation as if it had been manually signed. Electronic signature means any electronic process attached to or logically associated with a record and executed and adopted by a party with the intent to sign such record, including facsimile or email electronic signatures. Delivery of an executed copy of this Initial Debenture by electronic transmission or other means of electronic communication capable of producing a printed copy will be deemed to be execution and delivery of this Initial Debenture.

This Initial Debenture may only be transferred, upon compliance with the conditions prescribed in the Indenture, on the register(s) to be kept at the principal office of the Trustee in the City of Toronto and in such other place or places and/or by such other registrars (if any) as the Corporation with the approval of the Trustee may designate. No transfer of this Initial Debenture shall be valid unless made on the register by the registered holder hereof or his executors or administrators or other legal representatives, or his or their attorney duly appointed by an instrument in form and substance satisfactory to the Trustee or other registrar, and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe and upon surrender of this Initial Debenture for cancellation. Thereupon a new Initial Debenture or Initial Debentures in the same aggregate principal amount shall be issued to the transferee in exchange hereof.

This Initial Debenture shall not become obligatory for any purpose until it shall have been Authenticated by the Trustee under the Indenture.

Capitalized words or expressions used in this Initial Debenture shall, unless otherwise defined herein, have the meaning ascribed thereto in the Indenture. In the event of any inconsistency between the terms of this Initial Debenture and the Indenture, the terms of the Indenture shall govern.

IN WITNESS WHEREOF THE LIMESTONE BOAT COMPANY LIMITED has caused this Debenture to be signed by its authorized representatives as of                                                    , 20        .
