PROSPECTUS

DIRTT Environmental Solutions Ltd.

SUBSCRIPTION RIGHTS TO PURCHASE UP TO            SHARES

OF COMMON SHARES AT C$            PER SHARE

DIRTT Environmental Solutions Ltd. (“we,” “us,” “our,” or the “Company”) is distributing, at no charge, to holders of our Common Shares (“Common Shares”) as of the close of business on            (the “Record Date”), transferable subscription rights (the “Rights”) to purchase up to an aggregate of             of our Common Shares in Canada and the United States of America (the “Offering”). This prospectus also registers, under the laws of the United States of America, the issuance of our Common Shares upon exercise of the Rights distributed to holders of Common Shares. If you are a resident in or otherwise subject to the securities laws of Canada, you should refer to the rights offering circular (the “Canadian Circular”) filed on our SEDAR+ profile at www.sedarplus.ca. Each holder will receive one Right for each Common Share owned by such holder at the close of business on the Record Date. Each Right will entitle its holder to purchase              Common Shares at a subscription price of C$            per full share (the “Subscription Price”), exercisable for whole Common Shares only on or before            (the “Expiration Time”) on            (the “Expiration Date”) (the “Basic Subscription Privilege”). As a result,              Rights are required to subscribe for one whole Common Share.

The Company expects to use the proceeds of the Offering for general corporate purposes, which may include investments in its business, funding potential future cash needs or operating losses, funding working capital and capital expenditure needs, or reductions to its outstanding indebtedness. The Company may seek to reduce its outstanding indebtedness by any one or more of several means, including open market or privately negotiated repurchases, tender offers, or redemptions of its Debentures (as defined herein), or through prepayments or repayment of necessary operating lease facilities and amounts outstanding under the Leasing Facilities (as defined herein). See “Use of Proceeds” in this prospectus for a further explanation of our intended use of proceeds from this Offering. If we sell all the Common Shares being offered in this Offering, we will receive gross proceeds of approximately C$            .

The Rights and the Common Shares issuable upon the exercise of the Rights (collectively, the “Offered Securities”) are expected to be listed on the Toronto Stock Exchange (the “TSX”) under the symbol “            ” and “DRT”, respectively.

The Rights issued pursuant to this Offering will be granted and exercisable beginning on or about            . The Rights will expire and will have no value if they are not exercised prior to the 5:00 pm (Eastern Time) on            , the Expiration Date of this Offering. Computershare Investor Services, Inc. (“Computershare”) will serve as the subscription agent in the Offering.

You should carefully consider whether to exercise your Rights before the expiration of the Offering and review carefully the information contained in or incorporated by reference in this prospectus and any accompanying prospectus supplement or any free writing prospectus that we have authorized for use in connection with this Offering prior to exercising such Rights. All exercises of Rights are irrevocable once they are exercised. Our board of directors (our “Board”) is making no recommendation regarding your exercise of the Rights. Holders who do not participate in the Offering will continue to own the same number of Common Shares. Holders who do not subscribe for the greatest number of shares permitted in the Offering will own a smaller percentage of the total Common Shares outstanding if and to the extent other holders fully exercise their Basic Subscription Privileges and Additional Subscription Privileges (as defined herein) or in the Standby Commitments. Rights that are not exercised by the Expiration Time on the Expiration Date will expire and have no value.

If you exercise your Basic Subscription Privilege in full (other than those Rights to acquire less than one whole Common Share, which cannot be exercised) and our other holders do not fully exercise their Basic Subscription Privileges, you may also exercise an additional subscription privilege (the “Additional Subscription Privilege”) to purchase additional Common Shares not issued under the Basic Subscription Privilege, subject to availability and pro rata allocation of shares among persons exercising the Additional Subscription Privilege. No fractional Common Shares will be issued. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the shareholder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be cancelled without any repayment of capital or other consideration therefor.

The Company expects to enter into a Standby Purchase Agreement (the “Standby Purchase Agreement”) with each of 22NW (as defined herein) and 726 (as defined herein) (together with 22NW, the “Standby Purchasers”). As of the date hereof, 22NW (and its affiliates) and 726 (and its affiliates) hold 23,136,229 and 18,255,664 issued and outstanding Common Shares, representing approximately 22.1% and 17.4% of the issued and outstanding Common Shares, respectively. Pursuant to the Standby Commitments (as defined herein), each Standby Purchaser will agree to exercise its Basic Subscription Privilege in full and, in addition thereto, to collectively purchase Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege, so that            Common Shares will be sold and the Company will realize gross proceeds of C$            under the Offering (collectively, the “Standby Commitments”), assuming each of the Standby Purchasers satisfies their Standby Commitment.

Our issued and outstanding Common Shares are listed on the TSX under the trading symbol “DRT” and are quoted on the OTC Markets (“OTC”) on the “OTC Pink Tier” under the symbol “DRTTF.” On November 9, 2023, the closing price of the Common Shares was C$0.49 on the TSX and the last reported sales price on the OTC was US$0.37.

This Offering is being made directly by us. We are not using an underwriter or selling agent. The Subscription Price, and proceeds to us before expenses, is C$            per full share, for aggregate proceeds to us, before expenses, of C$             (or US$            ) assuming the Offering is fully subscribed.

Our Board is making no recommendation regarding your exercise of the Rights. You should carefully consider whether to exercise your Rights before the Expiration Date. You may not revoke or revise any exercises of Rights once made.

Completion of the Offering is not subject to raising a minimum amount of proceeds.

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012, and, as such, we have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings.

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 22 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

QUESTIONS AND ANSWERS RELATING TO THE RIGHTS OFFERING

SUMMARY OF THE RIGHTS OFFERING

Why are you reading this prospectus?

We are distributing, at no charge, to holders of our Common Shares as of the close of business on the Record Date, the Rights on the terms and conditions described in this prospectus. Each Right will entitle its holder to purchase          Common Shares at the Subscription Price, exercisable for whole Common Shares only, subject to the terms described in this prospectus. If you are a resident in or otherwise subject to the securities laws of Canada, you should refer to the Canadian Circular filed on our SEDAR+ profile at www.sedarplus.ca.

The purpose of this prospectus is to provide you with detailed information about the Offering and your rights and restrictions in respect thereof. This prospectus should be read in conjunction with any accompanying prospectus supplement and any free writing prospectuses filed after the date hereof.

The Company expects to use the proceeds of the Offering for general corporate purposes, which may include investments in its business, funding potential future cash needs or operating losses, funding working capital and capital expenditure needs, or reductions to its outstanding indebtedness. The Company may seek to reduce its outstanding indebtedness by any one or more of several means, including open market or privately negotiated repurchases, tender offers, or redemptions of its Debentures, or through prepayments or repayment of necessary operating lease facilities and amounts outstanding under the Leasing Facilities. See “Use of Proceeds.”

What is being offered?

We are distributing, at no charge, one Right for each one Common Share held by our holders of Common Shares as of the close of business on the Record Date, being                    .

What does one Right entitle you to receive?

The Basic Subscription Privilege of each Right will entitle you to purchase          Common Shares at the Subscription Price of C$            per whole Common Share, exercisable for whole Common Shares only. You may not exercise your Rights to acquire less than one whole Common Share, meaning             Rights and payment of C$             is required to purchase one whole Common Share.

If you fully exercise your Basic Subscription Privilege (other than those Rights to acquire less than one whole Common Share, which cannot be exercised) and our other shareholders do not fully exercise their Basic Subscription Privileges, you may also exercise an Additional Subscription Privilege to purchase additional Common Shares not issued under the Basic Subscription Privilege, subject to the availability and pro rata allocation of Common Shares among shareholders exercising this Additional Subscription Privilege. To the extent the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, then the available Common Shares will be prorated among those who properly exercised Additional Subscription Privileges based on the number of Common Shares that such Rights holder subscribed for under the Basic Subscription Privilege compared to the total number of Common Shares subscribed for under the Basic Subscription Privilege by the holders properly exercising the Additional Subscription Privilege. If this pro rata allocation results in any shareholder receiving a greater number of Common Shares than the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, then such shareholder will be allocated only that number of Common Shares for which the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, and the remaining Common Shares will be allocated among all other shareholders exercising the Additional Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Common Shares have been allocated or all Additional Subscription Privilege exercises have been fulfilled, whichever occurs earlier.

7

No fractional Common Shares will be issued. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the holder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be cancelled without any repayment of capital or other consideration therefor. Rights will be evidenced by a Rights DRS Advice issued under the direct registration system administered by the subscription agent.

To exercise your Rights, you must complete the subscription form (the “Subscription Form”) included with the Rights DRS Advice and deliver it to the subscription agent, together with full payment for all the Rights you elect to exercise under the Basic Subscription Privilege and Additional Subscription Privilege, before the expiration of the Offering. You may deliver the required documents and payments by mail or commercial carrier. If regular mail is used for this purpose, we recommend using registered mail, properly insured, with return receipt requested.

If you are a beneficial owner of Common Shares that are registered in the name of a broker, dealer, bank or other nominee, you should instruct the Registered Holder of your Common Shares to exercise your Rights on your behalf and deliver all required documents and payment before the Expiration Time on the Expiration Date. You should contact the Registered Holder of the rights as soon as possible as they may establish an earlier deadline for receiving subscription instructions. See “Questions and Answers Related to the Rights Offering—How to Exercise the Rights.”

What is the Subscription Price?

The Subscription Price for each Common Share issuable pursuant to an exercise of Rights (whether under the Basic Subscription Privilege or the Additional Subscription Privilege) is C$             per whole Common Share, payable by money order, bank draft or certified check. To be effective, any payment related to the exercise of a Right must clear prior to the Expiration Time on the Expiration Date.

On                    , 2023, being the last trading day before the announcement of the terms of the Offering and the determination of the Subscription Price, the closing price of the Common Shares was C$            on the TSX and the last reported sales price was US$            on the OTC.

In accordance with the TSX Company Manual, the Subscription Price must be at least a         % discount to the market price (as defined under TSX rules) of our Common Shares.

When does the Offering expire?

The Rights may be exercised until the expiration of the Offering, which is            Eastern Time, on            . Any Rights not exercised at or before the expiration of the Offering will be void and of no value.

What are the significant attributes of the Rights issued under the Offering and the securities to be issued upon the exercise of the Rights?

The Rights entitle the holder to purchase          Common Shares at the Subscription Price, exercisable for whole Common Shares only, pursuant to the Basic Subscription Privilege and, if available, the Additional Subscription Privilege, until the Expiration Time on the Expiration Date.             rights are required to subscribe for one whole Common Share. No fractional Common Shares will be issued. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the holder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be canceled without any repayment of capital or other consideration therefor. The Rights are transferable and are expected to be listed on the TSX under the symbol “            .” See “Where will the Rights and Common Shares issuable upon the exercise of the Rights be listed for trading?” for more information.

A holder of Rights is not, by reason of owning the Rights, a shareholder of the Company and does not have any rights of a shareholder.

8

The Rights are exercisable for fully paid and non-assessable Common Shares. We are authorized to issue an unlimited number of Common Shares, of which 104,789,358 are issued and outstanding as of November 9, 2023. Holders of Common Shares are entitled to receive notice of and to one vote per Common Share held at meetings of our shareholders, to receive such dividends (if any) as our Board may declare, and to share equally in such remaining assets of the Company as are distributable to shareholders upon its liquidation, dissolution or winding-up.

What are the minimum and maximum number or amount of Common Shares that may be issued under the Offering?

The Offering is not subject to any minimum subscription level. However, the Company has the Standby Commitments from the Standby Purchasers to collectively subscribe for up to            Common Shares that will ensure aggregate proceeds from the Offering of C$            , assuming each of the Standby Purchasers satisfies its Standby Commitment. See “—Standby Commitment” and “—Insider Participation.”

Assuming the exercise of all Rights,             Common Shares will be issued in connection with the Offering (subject to adjustment for rounding) for aggregate gross proceeds of C$            .

Where will the Rights and Common Shares issuable upon the exercise of the Rights be listed for trading?

Our outstanding Common Shares are listed on the TSX under the symbol “DRT” and quoted on the OTC under the symbol “DRTTF.” The Rights are expected to be listed on the TSX under the symbol “            ” until 12:00 pm (Eastern Time) on the Expiration Date, at which time the Rights will be halted from trading.

We do not intend to apply for the Rights to be quoted on any market tiers of the OTC. However, since broker-dealers can trade securities on the OTC Pink Tier without our involvement, it is possible that such market participants may make a market in our Rights on the OTC. Although the Rights are expected to be listed on the TSX, the Company does not intend to facilitate trading of the Rights on a U.S. national securities exchange or on the OTC. Accordingly, it may be difficult to facilitate sales or transfers of rights in the U.S., and any market that could develop for the Rights in the U.S. will likely be illiquid and volatile.

Will this Offering result in the Company “going private” for purposes of Rule 13e-3 of the Exchange Act?

The Offering is not a transaction or series of transactions which has either a reasonable likelihood or a purpose of producing a “going private effect” as specified in Rule 13e-3 of the Exchange Act. The Offering may, however, substantially affect the ownership of the Company’s capital stock, especially if our current shareholders (other than the Standby Purchasers) do not exercise their Basic Subscription Privilege.

IMPORTANT DATES AND TIMES

USE OF AVAILABLE FUNDS

What will our available funds be upon the closing of the Offering?

Assuming the exercise of all of the Rights, the maximum net proceeds to the Company from the Offering will be approximately C$             , after deducting estimated expenses of C$             associated with the Offering. The following table sets out our estimate of the Company’s available funds after giving effect to the Offering:

10

How will we use the available funds?

The Company expects to use the proceeds of the Offering for general corporate purposes, which may include investments in its business, funding potential future cash needs or operating losses, funding working capital and capital expenditure needs, or reductions to its outstanding indebtedness. The Company may seek to reduce its outstanding indebtedness by any one or more of several means, including open market or privately negotiated repurchases, tender offers, or redemptions of its Debentures, or through prepayments or repayment of necessary operating lease facilities and amounts outstanding under the Leasing Facilities. There can be no assurance that the Company will be able to successfully reduce its outstanding indebtedness, on favorable terms or at all.

The following table sets out how we intend to use our available funds raised. We intend to spend the available funds as stated. We will reallocate funds only for sound business reasons. Management will have discretion in the actual application of the available funds. Any use of the available funds will be in furtherance of our business and consistent with our business objectives. We intend to invest the net proceeds of this Offering that we do not immediately use, and such investments may include short-term marketable investment grade securities.

How long will the available funds last?

The Company believes it has sufficient liquidity to remain a going concern for at least the next 12 months. The Company expects to use the net proceeds from the Offering as stated above within 12 months following the closing of the Offering.

INSIDER PARTICIPATION

Will insiders be participating in the Offering?

22NW Fund, LP (“22NW”) and 726 BC LLC and 726 BF LLC (collectively, “726”), are expected to agree, upon and subject to the terms and conditions of the Standby Purchase Agreement, to participate in the Offering. Aron English is a director of the Company and manager of 22NW Fund GP, LLC, the general partner of 22NW.

11

Shaun Noll is a director of the Company and President and Chief Investment Officer of 726. As of the date hereof, 22NW (and its affiliates) and 726 (and its affiliates) hold 23,136,229 and 18,255,664 issued and outstanding Common Shares, representing approximately 22.1% and 17.4% of the issued and outstanding Common Shares, respectively. As of the date hereof, 22NW owns C$18.9 million principal amount of the January Debentures (as defined herein) and C$13.6 million principal amount of the December Debentures (as defined herein).

Specifically, pursuant to the Standby Purchase Agreement, 22NW and 726 will each agree to exercise its Basic Subscription Privilege in full, and in addition thereto, to purchase from the Company, at the Subscription Price, 50% and 50%, respectively, of all Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege.

As a result of the Standby Commitments, the maximum number of Common Shares issuable under the Offering to which the Standby Purchasers will commit (being an aggregate of            Common Shares) will be sold and the Company will realize gross proceeds of not less than C$            thereunder. See “—Standby Commitment.”

Directors and executive officers of the Company may potentially elect to participate in the Offering with respect to Rights distributed in respect of their Common Shares that they own as of the Record Date. There is, however, no obligation to do so (other than the respective obligations of each Standby Purchaser) and the Company provides no assurances in this regard. It is expected that some of the directors and executive officers of the Company will participate in the Offering, but there is no guarantee that they will do so.

Who are the holders of 10% or more of our securities before and after the Offering?

To the knowledge of our directors and executive officers, as of the date of this prospectus the only persons who currently hold 10% or more of the issued and outstanding Common Shares or who may own 10% or more upon completion of the Offering, are as set out in the following table:

If no Rights are exercised by any person other than the Standby Purchasers and all              Common Shares issuable under the Offering are acquired by the Standby Purchasers pursuant to the terms of the Standby Purchase Agreement, 22NW and 726 would hold and issued and outstanding Common Shares, representing approximately         % and         %, respectively, of the issued and outstanding Common Shares after the completion of the

12

Offering. For additional information, please see “Risk Factors—If the holders of our Common Shares (other than the Standby Purchasers) do not exercise their Rights and the Standby Purchasers perform their Standby Commitments, the Standby Purchasers would experience an increase in ownership of our Common Shares after the completion of the Offering and would be able to exercise a more significant level of control over the Company.”

DILUTION

If you do not exercise your Rights, by how much will your security holdings be diluted?

If you wish to retain your current percentage ownership of the Common Shares, you should exercise your Rights and pay the Subscription Price for the Common Shares to which you are entitled to subscribe for under the Basic Subscription Privilege. If you do not exercise your Rights or elect to sell or transfer your Rights, the value of the Common Shares currently held by you will be diluted as a result of the exercise of Rights by others. Assuming issuance of the maximum number of Common Shares under the Offering (             Common Shares), and that you do not exercise any Rights and so do not acquire any Common Shares pursuant to the Offering, then your shareholdings will be diluted by approximately        %.

STANDBY COMMITMENT

Who are the Standby Purchasers and what are the fees?

The Company expects to enter into the Standby Purchase Agreement, pursuant to which each Standby Purchaser will agree to exercise its Basic Subscription Privilege in full and, in addition thereto, to collectively purchase all Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege, so that             Common Shares will be sold and the Company will realize gross proceeds of C$            under the Offering.

Specifically, pursuant to the Standby Purchase Agreement, 22NW and 726 will each agree to exercise its Basic Subscription Privilege in full, and in addition thereto, to purchase from the Company at the Subscription Price, 50% and 50%, respectively of all Common Shares not issued under the Basic Subscription Privilege or Additional Subscription Privilege, or up to            Common Shares each. The allocation of the Common Shares purchased by 726 pursuant to the Standby Purchase Agreement will be determined by Shaun Noll in his sole discretion.

The Standby Commitments will ensure the Company realizes gross proceeds under the Offering of C$            . 22NW and 726 currently hold approximately 22.1% and 17.4%, respectively, of the outstanding Common Shares and, as a result, will be entitled (and required under their Standby Commitments) to purchase          and          Common Shares with an aggregate subscription price of approximately C$            and C$            (collectively, C$            ) under their respective Basic Subscription Privileges. The Standby Purchasers may also exercise their Additional Subscription Privilege, subject to the availability and pro rata allocation of Common Shares among shareholders exercising their Additional Subscription Privilege. Under the Standby Commitments, each Standby Purchaser is required to purchase 50% of all Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege in addition to the exercise of such Standby Purchaser’s Basic Subscription Privilege in full and the exercise of its Additional Subscription Privilege, if any.

22NW and 726 is each a related party of the Company on the basis that each holds, together with its joint actors, more than 10% of the outstanding Common Shares. Further, Aron English, a director of the Company, is a

13

manager of 22NW Fund GP, LLC, the general partner of 22NW. Shaun Noll, a director of the Company, is the President and Chief Investment Officer of 726. The Standby Purchasers will not receive any fee for providing the Standby Commitments.

The Standby Purchase Agreement contains certain conditions precedent that must be satisfied by the closing of the Offering, and if any such conditions precedent are not satisfied (or waived by the Standby Purchasers) or the Offering is otherwise terminated or cancelled, the Standby Purchase Agreement may be terminated by the Standby Purchasers. The Standby Purchase Agreement may also be terminated by the Standby Purchasers if (i) any order is made by a competent regulatory authority, and remains in effect, to cease trading the securities of the Company; or (ii) the closing of the Offering has not occurred on or before            , provided that the Standby Purchaser seeking to terminate the Standby Purchase Agreement has not been the cause of the failure to close the Offering on or before            . The Company may terminate the Standby Purchase Agreement if the closing of the Offering has not occurred or the Offering is otherwise terminated or canceled on or before             , provided the Company has used commercially reasonable efforts to comply with its obligations under the Standby Purchase Agreement.

The foregoing is a summary of certain terms of the Standby Purchase Agreement and is qualified in its entirety by reference to the full text of the Standby Purchase Agreement, a copy of which have been filed with the SEC, available on the SEC’s website at www.sec.gov, and on SEDAR+, available under the Company’s issuer profile at www.sedarplus.ca.

What are the security holdings of the Standby Purchasers before and after the Offering?

To the knowledge of our directors and executive officers, each of the Standby Purchaser’s holdings of Common Shares, before and after the completion of the Offering, are set out in the following table.

MANAGING DEALER, SOLICITING DEALER AND UNDERWRITING CONFLICTS

The Company has not retained any managing dealer, soliciting dealer or other party to solicit subscriptions for Common Shares pursuant to the Offering.

HOW TO EXERCISE THE RIGHTS

How does a shareholder that is a Registered Holder participate in the Offering?

If you hold your Common Shares in your own name, you are a “Registered Holder.” In order to exercise the Rights represented by the Rights DRS Advice, the holder of Rights must complete and deliver the Subscription

14

Form to the subscription agent in the manner set out below under the heading “How to Complete the Rights Subscription Form.” All exercises of Rights are irrevocable once submitted. If you wish to participate in this Offering, you must take the following steps, unless your Common Shares are held by a broker, bank, or other nominee:

If you send a payment that is insufficient to purchase the number of Common Shares you requested, or if the number of Common Shares you requested is not specified in the Subscription Form, the payment received will be applied to exercise your Basic Subscription Privilege. Unless you have specified the number of Common Shares you wish to purchase upon exercise of your Additional Subscription Privilege, any payment in excess of that required to exercise your Basic Subscription Privilege will be refunded. If the payment exceeds the Subscription Price for the full exercise of the Basic Subscription Privilege and Additional Subscription Privilege (to the extent specified by you and subject to pro rata allocation), the excess will be refunded. You will not receive interest on any payments refunded to you under this Offering.

Payment Methods

Your payment of the Subscription Price must be made in Canadian dollars for the full number of Common Shares for which you are subscribing by certified check, bank draft or money order payable to the subscription agent. The subscription agent will accept payment only by certified check, bank draft or money order payable to the subscription agent.

Your payment will be considered received by the subscription agent only upon receipt by the subscription agent of any certified check, bank draft or money order payable to the subscription agent. You should deliver your Subscription Form and payment of the Subscription Price to the subscription agent by one of the methods described below:

Your Rights balance is stated on the Rights DRS Advice.

Subscription Instructions

Basic Subscription Privilege: A holder or transferee of the Rights DRS Advice wishing to subscribe for Common Shares must complete Box 1 on the Subscription Form and deliver the Subscription Form together with

15

payment in full of the Subscription Price to the subscription agent at its office shown above prior to the Expiration Time on the Expiration Date.

Additional Subscription Privilege: To subscribe for additional Common Shares, holders must complete Box 2 on the Subscription Form. Shareholders can only submit a request for additional Common Shares if all available Common Shares under the Basic Subscription Privilege (outlined above) have been subscribed for. Under the Additional Subscription Privilege, holders of Rights may subscribe for any amount of additional Common Shares, up to              Common Shares minus the number of shares subscribed for pursuant to their Basic Subscription Privilege, being the maximum amount of Common Shares that may be issued in the Offering. Payment for additional Common Shares should be combined with the payment for the Basic Subscription Privilege on one certified check, bank draft or money order made out to Computershare Investor Services Inc. A refund check will be issued for any additional Common Shares requested and not issued.

To Sell, Transfer, Divide, Or Combine Rights

To sell or transfer your Rights, please see the instructions provided with the Rights DRS Advice. Note that the Rights expire at the Expiration Time on the Expiration Date. If you plan on selling or transferring your Rights, ensure to provide ample time for intermediary processing.

To divide or combine your Rights, please send your Rights DRS Advice together with a letter of instruction detailing the combination or division of Rights and mail to Computershare Investor Services Inc. at one of the addresses of the subscription agent listed above. If you are dividing or combining your Rights, the registered name must remain the same. If you want to change the registered name of the Rights, refer to the transfer instructions contained in the Rights DRS Advice. Note that the Rights expire at the Expiration Time on the Expiration Date. If you plan on dividing or combining your Rights, ensure to provide ample time for intermediary processing.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance of any subscription will be determined by the Company in its sole discretion, and any determination by the Company will be final and binding on the Company and its shareholders. The Company reserves the right to reject any subscription if it is not in proper form or if the acceptance thereof or the issuance of Common Shares pursuant thereto could be unlawful. The Company also reserves the right to waive any defect in respect of any particular subscription. Neither the Company nor the subscription agent is under any duty to give any notice of any defect or irregularity in any subscription, nor will they be liable for the failure to give any such notice. Any holder of Rights that fails to complete their subscription in accordance with the foregoing instructions prior to the expiration of the Offering will forfeit their Rights under the Basic Subscription Privilege and the Additional Subscription Privilege attaching to those Rights.

16

How does a shareholder that is not a Registered Holder participate in the Offering?

If you hold your Common Shares in the name of a securities broker or dealer, bank or trust company or other participant (a “Participant”) in the book based system administered by the Canadian Depository for Securities. (“CDS”) or in the book based system administered by the Depository Trust Company (“DTC”), then your broker, bank, or other nominee is the Registered Holder of the Common Shares you own. As a beneficial owner, you should instruct the Registered Holder to exercise your Right on your behalf and deliver all required documents and payment before the expiration of the Offering. The Registered Holder must exercise the Rights on your behalf for the Common Shares you wish to purchase. You should contact the Registered Holder of the rights as soon as possible as they may establish an earlier deadline for receiving subscription instructions.

If you wish to participate in this Offering and purchase Common Shares, please promptly contact the Registered Holder of your Common Shares. You should contact the Registered Holder for instruction to participate in the Offering.

Who is eligible to receive Rights?

The Rights are being offered to holders of our Common Shares as of the close of business on the Record Date residing in the United States and all provinces and territories of Canada (the “Eligible Jurisdictions”). Shareholders not resident in Eligible Jurisdictions (“Ineligible Holders”) that are able to establish to the Company’s satisfaction, in its sole discretion, not later than            , that an offering to and subscription by such holder of Rights and Common Shares is lawful and in compliance with all securities and other laws applicable in the Eligible Jurisdictions and in the jurisdiction where such Ineligible Holder is resident and would not require that the Company file any document, take any proceeding, make any application, obtain any approval, give any notice or make any payment, in each case of any kind or nature whatsoever, including by delivering a representation letter in the form presented by the Company (an “Approved Holder”), will be eligible to receive Rights.

No Rights or Common Shares issuable upon exercise thereof are offered for sale, and no offers to purchase securities are solicited, in any jurisdiction that is not an Eligible Jurisdiction, or to or from Ineligible Holders.

Ineligible Holders will not receive a Rights DRS Advice and Subscription Form, but will be sent a letter advising (i) that their Rights will be held by the subscription agent, as agent for the benefit of all such Ineligible Holders, and (ii) how Ineligible Holders might establish their ability to participate in the Offering and subscribe for Common Shares as an Approved Holder, failing which the subscription agent will attempt to sell the Rights for the benefit of such Ineligible Holder.

What is the Additional Subscription Privilege and how can you exercise this privilege?

If you fully exercise your Basic Subscription Privilege (other than those Rights to acquire less than one whole Common Share, which cannot be exercised) and other shareholders do not fully exercise their Basic Subscription Privileges, you may also exercise an Additional Subscription Privilege to purchase additional Common Shares not issued under the Basic Subscription Privilege, subject to the availability and pro rata allocation of Common Shares among shareholders exercising this Additional Subscription Privilege. To the extent the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, then the available Common Shares will be prorated among those who properly exercised their Additional Subscription Privilege based on the number of Common Shares that such Rights holder subscribed for under the Basic Subscription Privilege compared to the total number of Common Shares subscribed for under the Basic Subscription Privilege by the holders properly exercising the Additional Subscription Privilege. If this pro rata allocation results in any shareholder receiving a greater number of Common Shares than the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, then such shareholder will be allocated only that number of Common Shares for which the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, and the remaining Common Shares will be allocated among all other shareholders exercising the Additional Subscription

17

Privilege on the same pro rata basis described above. The proration process will be repeated until all Common Shares have been allocated or all Additional Subscription Privilege exercises have been fulfilled, whichever occurs earlier. You may only request additional Common Shares pursuant to the Additional Subscription Privilege once, as you will not be able to participate in multiple rounds of the Additional Subscription Privilege as the number of subscribers under the Additional Subscription Privilege becomes known. Accordingly, you should request the maximum number of Common Shares you wish to subscribe for when you complete and deliver the Subscription Form. See “The Rights Offering—Instructions for Completing Your Subscription Form” for additional information.

Shareholders who wish to maximize their allocation in the Offering should exercise their Basic Subscription Privilege in full and exercise their Additional Subscription Privilege for the maximum amount of Common Shares they are willing to purchase, up to the maximum number of Common Shares that may be issued in the Offering. However, to the extent the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, then the available Common Shares will be prorated in accordance with the proration process described above.

If you wish to retain your current percentage ownership of the Common Shares, you should exercise your Rights and pay the Subscription Price for the Common Shares to which you are entitled to subscribe for under the Basic Subscription Privilege. If you do not exercise your Rights or elect to sell or transfer your Rights, the value of the Common Shares currently held by you will be diluted as a result of the exercise of Rights by others.

The following is an illustrative example of the proration process described above in the event the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, assuming that there are 1,000 Common Shares available for subscription under this Offering, with the following holders participating as set forth below such that 200 Common Shares remain unsubscribed for following the exercise of the Basic Subscription Privilege. In this illustrative example, no Common Shares would be issued pursuant to the Standby Purchase Agreement.

The following is an illustrative example of the proration process described above in the event there are Common Shares not issued under the Basic Subscription Privilege, assuming that there are 1,000 Common Shares available for subscription under this Offering, with the following holders participating as set forth below such that 700 Common Shares remain unsubscribed for following the exercise of the Basic Subscription Privilege. In this illustrative example, 300 Common Shares would be issued to the Standby Purchasers pursuant to the Standby Purchase Agreement.

18

How does a Rights holder sell or transfer Rights?

The Rights will be transferable during the course of the Offering. We expect the Rights will trade on the TSX under symbol “            ”, beginning on             , until 12:00 p.m., Eastern Time, on the Expiration Date. As a result, you may transfer or sell your Rights during the course of the subscription period if you do not want to purchase any Common Shares. The Rights are a new issue of securities, however, and do not have an established trading market. We cannot give you any assurance that a market for the Rights will develop or, if a market does develop, as to how long it will continue or at what prices the Rights will trade. Therefore, we cannot assure you that you will be able to sell any of your Rights or as to the value you may receive in a sale. The subscription agent will only facilitate subdivisions or transfers of the Rights until             , Eastern Time, on             , business days prior to the Expiration Date.

When can you trade securities issuable upon the exercise of your Rights?

The outstanding Common Shares are listed on the TSX under the symbol “DRT” and are quoted on the OTC under the symbol “DRTTF.” We expect the Rights and the Common Shares issuable upon the exercise of the Rights will be listed on the TSX. We anticipate that the Rights will be listed and available for trading on                 , 2023.

Are there restrictions on the resale of Rights?

Canada

The Offered Securities are being distributed by the Company in Canada pursuant to exemptions from the prospectus requirements under Canadian securities laws. Resale of the Offered Securities may be subject to restrictions pursuant to applicable securities legislation then in force. Set out below is a general summary of the restrictions governing first trades in the Offered Securities in Canada. Additional restrictions may apply to “insiders” of the Company and holders of the Common Shares who are “control persons” or the equivalent or who are deemed to be part of what is commonly referred to as a “control block” in respect of the Company for purposes of Canadian securities legislation. Each holder of Rights is urged to consult with his or her professional advisors to determine the exact conditions and restrictions applicable to trades of the Offered Securities.

Generally, the first trade of any of the Offered Securities will be exempt from the prospectus requirements under Canadian securities legislation and such Offered Securities may be resold without hold period restrictions if: (i) the Company is and has been a “reporting issuer” in a jurisdiction of Canada for the four months immediately preceding the trade; (ii) the trade is not a “control distribution” as defined in applicable securities legislation; (iii) no unusual effort is made to prepare the market or to create a demand for the Offered Securities; (iv) no extraordinary commission or other consideration is paid in respect of such trade; and (v) if the seller is an insider or officer of the Company, the seller has no reasonable grounds to believe that the Company is in default of applicable securities legislation.

If such conditions have not been met, then the Offered Securities may not be resold except pursuant to a prospectus or prospectus exemption, which may only be available in limited circumstances. As at the date hereof the Company has been a reporting issuer for more than four months in each of the provinces of Canada.

United States

There are no restrictions on the resale of Rights under applicable U.S. securities laws except for Rights acquired by affiliates of the Company or Rights distributed on Common Shares that are “restricted securities” under U.S. securities laws. Rights held by persons who are not affiliates of the Company will be freely transferable for resale without restrictions or further registration under the Securities Act of 1933 (the “Securities Act”). The resale limitations of Rule 144 promulgated under the Securities Act will apply to transfers of Rights by affiliates of the Company. Rights distributed on Common Shares that are “restricted securities” under U.S. securities laws will also be “restricted securities” and may not be transferred except in compliance with Rule 144, including its holding period (which will not be available during the Offering).

19

Will we issue fractional underlying securities upon exercise of the Rights?

No. The Basic Subscription Privilege of each Right will entitle you to purchase Common Shares at the Subscription Price of C$             per whole Common Share, exercisable for whole Common Shares only. You may not exercise your Rights to acquire less than one whole Common Share. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the holder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be canceled without any repayment of capital or other consideration therefor.

APPOINTMENT OF SUBSCRIPTION AGENT

Who is the subscription agent?

RISK FACTORS

An investment in our securities involves risks. Before you invest in our securities, you should carefully consider the following risk factors, as well as those risk factors included in our most recent Annual Report on Form 10-K, as supplemented by our Quarterly Reports on Form 10-Q, each of which is incorporated herein by reference, and all of the other information included in this prospectus, any prospectus supplement, any free writing prospectus and the documents we incorporate by reference in evaluating an investment in our securities.

Risk Related to our Common Shares and the Rights Offering

Our share price has been and may continue to be volatile, which could cause the value of your investment to decline.

Our Common Shares are listed on the TSX under the symbol “DRT” and are quoted on the OTC under the symbol “DRTTF.” The price of our Common Shares has in the past fluctuated significantly, and may fluctuate significantly in the future, depending upon a number of factors, many of which are beyond our control and may adversely affect the market price of our Common Shares. These factors include: (i) variations in quarterly results of operations; (ii) deviations in our earnings from publicly disclosed forward-looking guidance; (iii) changes in earnings estimates by analysts; (iv) our announcements or our competitors’ announcements of significant contracts, acquisitions, strategic partnerships or joint ventures; (v) general conditions in the offsite construction and manufacturing industries; (vi) sales of our Common Shares by our significant shareholders; (vii) fluctuations in stock market price and volume; and (viii) other general economic conditions.

In the past, following periods of volatility in the trading price of a company’s securities, securities class action litigation has been brought against that company. If our share price is volatile, we may become the target of securities litigation in both the United States and Canada. Securities litigation could result in substantial costs and divert management’s attention and resources from our business and could have an adverse effect on our business, financial condition and results of operations.

Our Common Shares are quoted on the OTC’s Pink Tier, and there may be a limited trading market in the Company’s Common Shares in the United States. As a result of the limited trading market, investors may experience limited liquidity, and may experience limited ability to sell shares in the open market.

Our Common Shares are quoted on the OTC’s Pink Tier under the symbol “DRTTF.” There may be a limited trading market in the Company’s Common Shares in the United States. As a result of the limited trading market of our Common Shares, investors in our Common Shares may experience limited demand for their shares of Common Shares, which may limit their ability to sell their shares in the open market.

Although we anticipate the Rights will be listed on the TSX, there is currently no market through which the Rights may be sold and no guarantee that an active trading market will develop.

The Rights are expected be listed on the TSX, however, there is currently no market through which the Rights may be sold and purchasers may not be able to resell Rights purchased under this prospectus and any accompanying prospectus supplement. This may affect the pricing of the Rights in the secondary market, the transparency and the availability of trading prices, the liquidity of the securities and the extent of issuer regulation. There can be no assurance that an active trading market will develop for the Rights, or if developed, that such a market will be sustained. We anticipate the Rights will be transferable until 12:00 pm (Eastern Time) on the Expiration Date at which time the Rights will be halted from trading and they will be no longer transferable. Since the Rights will not be listed on a U.S. securities exchange, holders of Rights will not be able to sell or transfer the Rights on a U.S. securities exchange. Therefore, such sales or transfers may be more difficult to facilitate.

We do not intend to apply for the Rights to be quoted on any market tiers of the OTC. However, since broker-dealers can trade securities on the OTC Pink Tier without our involvement, it is possible that such market

22

participants may make a market in our Rights on the OTC. Although the Rights are expected to be listed on the TSX, the Company does not intend to facilitate trading of the Rights on a U.S. national securities exchange or on the OTC. Accordingly, it may be difficult to facilitate sales or transfers of rights in the U.S., and any market that could develop for the Rights in the U.S. will likely be illiquid and volatile.

This Offering may cause the price of our Common Shares to decrease and you may be able to purchase our Common Shares on the open market at a price below the Subscription Price.

The announcement of this Offering, the Subscription Price, and the number of Common Shares we could deliver if this Offering is completed could result in an immediate decrease in the trading price of our Common Shares. This decrease may occur before the expiration of this Offering and continue after consummation of this Offering. If such a decrease occurs, your purchase of Common Shares in this Offering may be at a price greater than the prevailing trading price. Further, if a substantial number of Rights are exercised and the holders of Common Shares received upon exercise of those Rights choose to sell some or all of those shares, the resulting sales could depress the market price of our Common Shares. Accordingly, you may be able to purchase our Common Shares on the open market at a price below the Subscription Price. The last reported sale price of our Common Shares on the TSX on             was C$            and the last reported sales price on the OTC was US$            .

The market price of the Rights and the Common Shares may be volatile and could be subject to fluctuations.

The market price of the Rights and the underlying Common Shares may be volatile and subject to wide fluctuations and will be based on a number of factors, including, without limitation: (i) the overall condition of the equity markets; (ii) the markets for similar securities; (iii) the financial condition, results of operation and prospects of us; (iv) the publication of earnings estimates for us or other research reports and speculation regarding us in the press or investment community; (v) changes in the industry in which we operate and competition affecting us; (vi) general market and economic conditions; (vii) the market reaction to the COVID-19 pandemic and its impact on the Company; (viii) acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving us or our competitors; or (ix) the other risks described or referred to in this prospectus and any accompanying prospectus supplement and in the documents incorporated by reference herein. The condition of the equity markets and price of our Common Shares have fluctuated significantly in recent years and are likely to continue to fluctuate in the future. Fluctuations in these factors could have an adverse effect on the market price of the Rights and the Common Shares.

The volatility may affect the ability of holders of Rights to sell the Rights at a favorable price. Additionally, volatility in the market price of the Common Shares may result in greater volatility in the market price of the Rights.

The Subscription Price determined for the Offering is not an indication of the fair value of our Common Shares.

The Subscription Price in the Offering is equal to C$            , which is significantly lower than the closing price of our Common Shares on             of C$             on the TSX. In accordance with the TSX Company Manual, the Subscription Price must be at least a     % discount to the market price (as defined under TSX rules) of our Common Shares. The Subscription Price does not necessarily bear any relationship to the book value of our assets, net worth, past operations, cash flows, losses, financial condition, or any other established criteria for valuing the Company. You should not consider the Subscription Price an indication of the value of the Company or our Common Shares. You should not assume or expect that, after the Offering, our Common Shares will trade at or above the Subscription Price. We can give no assurance that our Common Shares will trade at or above the Subscription Price in any given time period.

23

You may not revoke your exercise of your Rights, and your purchase of Common Shares in the Offering may be at a price higher than the market price.

Once you exercise your Rights, you may not revoke the exercise even if you later learn information that you consider to be unfavorable to the exercise of your Rights.

The public trading market price of our Common Shares may decline before the Rights expire. If you exercise your Rights and, afterwards, the market price of our Common Shares falls below the Subscription Price, then you will have committed to buy Common Shares in the Offering at a price that is higher than the market price. Moreover, we cannot assure you that you will ever be able to sell Common Shares that you purchased in the Offering at a price equal to or greater than the Subscription Price. You should not exercise your Rights unless you are certain that you wish to purchase additional shares of our Common Shares at a Subscription Price of C$            per Common Share.

Until your account at your broker, custodian bank or other nominee is credited upon expiration of the Offering, you may not be able to sell the Common Shares that you purchase in the Offering. We will credit your account at your broker, custodian bank or other nominee with our Common Shares, electronically in registered, book-entry form only on our records or on the records of our transfer agent, Computershare, that you purchased pursuant to your Basic Subscription and Additional Subscription Privileges as soon as practicable after the Offering has expired and all proration calculations, reductions, and additions contemplated by the terms of the Offering have been effected.

You will need to act promptly and to carefully follow the subscription instructions, or your exercise of Rights will be rejected.

Shareholders who desire to purchase Common Shares in this Offering must act promptly to ensure that all required forms and payments are actually received by the subscription agent prior to the Expiration Time on the Expiration Date. If you are a beneficial owner of Common Shares, you must act promptly to ensure that your broker, dealer, custodian bank or other nominee acts for you and that all required forms and payments are actually received by the subscription agent prior to the expiration of the subscription period. You should contact the Registered Holder of the rights as soon as possible as they may establish an earlier deadline for receiving subscription instructions. We are not responsible if your broker, dealer, custodian bank or nominee fails to ensure that all required forms and payments are actually received by the subscription agent prior to the Expiration Time on the Expiration Date. If you fail to complete and sign the required Subscription Forms, or you send an insufficient payment amount, or your payment does not clear, or you otherwise fail to follow the subscription procedures that apply to your exercise in this Offering prior to the Expiration Time on the Expiration Date, the Company may, depending on the circumstances, reject your subscription or accept it only to the extent of the payment received. Neither we, nor our subscription agent, will undertake to contact you concerning, or attempt to correct, an incomplete or incorrect Subscription Form or payment. We have the sole discretion to determine whether a subscription exercise properly follows the subscription procedures.

You will not receive interest on subscription funds, including any funds ultimately returned to you.

You will not earn any interest on your subscription funds while they are being held by the subscription agent pending the closing of this Offering. In addition, if you exercise your Additional Subscription Privilege and are not allocated all of the Common Shares for which you subscribe for pursuant to the exercise of the Additional Subscription Privilege, neither we nor the subscription agent will have any obligation with respect to the Rights except to return, without interest or deduction, any subscription payments to you.

You may not receive all of the Common Shares you subscribe for pursuant to the Additional Subscription Privilege.

If an insufficient number of Common Shares are available to fully satisfy all properly exercised Additional Subscription Privilege requests, the available Common Shares will be distributed proportionately among

24

shareholders who properly exercised their Additional Subscription Privileges based on the number of Common Shares each shareholder subscribed for under its Basic Subscription Privilege. If this pro rata allocation results in any shareholder receiving a greater number of Common Shares than the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, then such shareholder will be allocated only that number of shares for which the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, and the remaining Common Shares will be allocated among all other shareholders exercising the Additional Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Common Shares have been allocated or all over-subscription exercises have been fulfilled, whichever occurs earlier.

You may not be able to resell any of our Common Shares that you purchase pursuant to the exercise of Rights immediately upon expiration of the subscription period or be able to sell your shares at a price equal to or greater than the Subscription Price.

If you exercise your Rights, you may not be able to resell the underlying Common Shares until you or your broker, dealer, custodian bank or other nominee, if applicable, have received those shares. Moreover, you will have no rights as a holder of the Common Shares that you purchased in this Offering until we issue the shares to you. Although we will endeavor to issue the Common Shares promptly after completion of this Offering, there may be a delay between the Expiration Date and the time that the Common Shares are issued. In addition, we cannot assure you that, following the exercise of your Rights, you will be able to sell your Common Shares at a price equal to or greater than the Subscription Price.

If the holders of our Common Shares (other than the Standby Purchasers) do not exercise their Rights and the Standby Purchasers perform their Standby Commitments, the Standby Purchasers would experience an increase in ownership of our Common Shares after the completion of the Offering and would be able to exercise a more significant level of control over the Company.

The Standby Purchasers are expected to agree, upon and subject to the terms and conditions of the Standby Purchase Agreement, to participate in the Offering. As of the date hereof, 22NW (and its affiliates) and 726 (and its affiliates) hold 23,136,229 and 18,255,664 issued and outstanding Common Shares, representing approximately 22.1% and 17.4% of the issued and outstanding Common Shares, respectively. As of the date hereof, 22NW owns C$18.9 million principal amount of the January Debentures and C$13.6 million principal amount of the December Debentures.

If no Rights are exercised by any person other than the Standby Purchasers and all             Common Shares issuable under the Offering are acquired by the Standby Purchasers pursuant to the terms of the Standby Purchase Agreement, 22NW and 726 would hold             and             issued and outstanding Common Shares, representing approximately         % and         %, respectively, of the issued and outstanding Common Shares after the completion of the Offering. As a result, these shareholders collectively would be able to exercise a significant level of control over all matters requiring shareholder approval, including the election of directors, amendments to our amended and restated articles of amalgamation, and approval of significant corporate transactions, barring any requirement for such shareholder to recuse itself from any such vote pursuant to applicable securities law, corporate law or the rules and regulations of any applicable stock exchanges. Further, affiliates of 22NW and 726 also serve as directors on the Company’s Board of Directors. This control could have the effect of delaying or preventing a change of control of the Company or changes in management and would make the approval of certain transactions difficult or impossible without the support of these shareholders. Additionally, the perception that these shareholders would have the ability to control or significantly influence the Company could cause our Common Shares to be less attractive to certain investors or otherwise result in a decline in the trading price of our Common Shares. To the Company’s knowledge, 22NW and 726 are not acting in concert and do not constitute a “group” (as defined in Section 13(d)(3) of the Exchange Act).

If you do not fully exercise your Rights, your interest in us will be significantly diluted if and to the extent other shareholders fully exercise their Basic Subscription and Additional Subscription Privileges or the Standby Purchasers perform their obligations under their respective Standby Commitments.

If you do not choose to fully exercise your Rights, your percentage ownership interest in the Company will decrease if and to the extent other shareholders fully exercise their Basic Subscription and Additional Subscription Privileges. Further, due to the Standby Commitments, we expect the Standby Purchasers to purchase all remaining shares of Common Shares that are not subscribed for by others under the Basic Subscription Privilege or Additional Subscription Privilege. If you do not exercise your Rights at all, your percentage ownership in the Company could decrease significantly if and to the extent other shareholders fully exercise their Basic Subscription and Additional Subscription Privileges. In addition, if you do not exercise your Rights in full and the Subscription Price is less than the fair value of our Common Shares, you would experience immediate dilution of the value of your shares relative to what your value would have been had our Common Shares been issued at fair value. This dilution could be substantial.

Significant sales of our Common Shares, or the perception that significant sales may occur in the future, including by our insiders, may cause our share price to decline.

The sale of substantial amounts of the Rights or our Common Shares could adversely affect the price of these securities. Additionally, a significant portion of our outstanding Common Shares are held by our directors and executive officers. Resales of a substantial number of Common Shares by these shareholders, announcements of the proposed resale of substantial amounts of our Common Shares, or the perception that substantial resales may be made by such shareholders could adversely affect the market price of our Common Shares. We cannot foresee the impact of such potential sales on the market, but it is possible that if a significant percentage of Common Shares and Rights were attempted to be sold within a short period of time, the market for our Common Shares and Rights would be adversely affected. It is also unclear whether or not the market for our Common Shares (and any market that develops for our Rights) could absorb a large number of attempted sales in a short period of time, regardless of the price at which they might be offered.

In administering this Offering, we will be relying on statements, representations and other information provided to us by third parties.

In administering the exercising of Rights and the pro rating of Additional Subscription Privilege requests in this Offering, we will rely on the accuracy of various statements and representations provided to us by brokers, dealers, holders of Rights and other third parties. If these statements or representations are false or inaccurate, it may delay or otherwise negatively affect our or the subscription agent’s ability to administer this Offering in accordance with the terms and conditions described in this prospectus.

The receipt of Rights may be treated as a taxable distribution to U.S. Holders of our Common Shares.

We intend to take the position that the receipt of the Rights in this Offering, for U.S. federal income tax purposes, is non-taxable to U.S. Holders (as defined herein) of our Common Shares under Section 305(a) of the Internal Revenue Code of 1986, as amended (the “Code”). However, this position regarding the receipt of the Rights is not binding on the Internal Revenue Service (the “IRS”), or the courts. If this position is finally determined by the IRS or a court to be incorrect, whether on the basis that the issuance of the Rights is a “disproportionate distribution” under Section 305 of the Code or otherwise, the fair market value of the Rights would be taxable to a U.S. Holder as dividend income to the extent of our current or accumulated earnings and profits, computed under U.S. federal tax principles. Distributions in excess of our current and accumulated earnings and profits would be treated as a non-taxable return of capital to the extent of a U.S. Holder’s tax basis in its Common Shares and thereafter as capital gain from the sale or exchange of such Common Shares. For a detailed discussion, please see “Material United States Federal Income Tax Considerations.” U.S. Holders of our Common Shares are urged to consult their own tax advisors with respect to the tax consequences of the Offering.

26

We have historically not paid dividends on our Common Shares.

We have not declared or paid any dividends on Common Shares to date. The declaration and payment of dividends is at the discretion of the Board, taking into account our earnings, capital requirements and financial condition, restrictions on our ability to pay dividends under our credit facilities, and such other factors as the Board considers relevant. Restrictions on our ability to pay dividends under our C$15.0 million senior secured revolving credit facility, dated February 9, 2023, with the Royal Bank of Canada generally limits our ability to pay any dividends or make any other distribution on our outstanding capital shares.

We have broad discretion to use the net proceeds from the Offering.

We intend to use the net proceeds of the Offering in the manner described under “Use of Proceeds.” We maintain broad discretion to spend the proceeds in ways that we deem most efficient. The application of the proceeds to various items may not necessarily enhance the value of our Common Shares. Our failure to effectively utilize the net proceeds of the Offering could adversely affect our business and, consequently, could adversely affect the price of our Common Shares on the open market.

We may use a portion of the proceeds from the Offering to reduce our outstanding indebtedness; however, there can be no assurance that we will be able do so on favorable terms or at all.

We may use proceeds from the Offering to reduce our outstanding indebtedness, including through, among other things, potential repayment of required operating lease facilities and amounts outstanding under the Leasing Facilities, repayment of other debt types, open market or privately negotiated repurchases, tender offers, or redemptions of the Company’s outstanding Debentures. However, there can be no assurance that we will be successful in reducing our outstanding indebtedness, either on favorable terms or at all.

27

USE OF PROCEEDS

We estimate that the proceeds from this Offering will be approximately C$             (or US$            ), after deducting estimated expenses of C$             (or US$            ) associated with the Offering and assuming that all of the Common Shares being offered in the Offering are purchased at the Subscription Price. On November 9, 2023, the rate of exchange for the United States dollar, expressed in Canadian dollars, based on the Bank of Canada daily average exchange rate for United States dollars, was US$1.00 equals C$0.7256.

General Corporate and Working Capital

We may use a portion of the proceeds for general corporate purposes, which may include investments in our business, funding potential future cash needs or operating losses or funding working capital and capital expenditure needs.

Reduce Outstanding Indebtedness

We may use a portion of the proceeds from the Offering to reduce our outstanding indebtedness, including through, among other things, repayment of necessary operating lease facilities and amounts outstanding under the Leasing Facilities, or potential open market or privately negotiated repurchases, tender offers, or redemptions of our outstanding Debentures.

As of the date of this prospectus, the Company has: (i) C$40,250,000 principal amount outstanding of convertible unsecured subordinated debentures that will mature and be repayable on January 31, 2026 (the “January Debentures”) and (ii) C$35,000,000 principal amount outstanding of convertible unsecured subordinated debentures that will mature and be repayable on December 31, 2026 (the “December Debentures” and together with the January Debentures, the “Debentures”). The January Debentures accrue interest at the rate of 6.00% per annum payable semi-annually in arrears on the last day of January and July of each year commencing on July 31, 2021 until January 31, 2026. The December Debentures accrue interest at the rate of 6.25% per annum payable semi-annually in arrears on the last day of June and December of each year commencing on June 30, 2022 until December 31, 2026.

On February 12, 2021, the Company entered into a loan agreement governing a C$25.0 million senior secured revolving credit facility with the Royal Bank of Canada (“RBC”), as lender (the “RBC Facility”). On February 9, 2023, the Company extended the RBC Facility (the “Extended RBC Facility”). The Extended RBC Facility has a borrowing base of C$15 million and a one year term. Interest is calculated as at the Canadian or U.S. prime rate plus 75 basis points or the Canadian Dollar Offered Rate or Term Secured Overnight Financing Rate (“SOFR”) plus 200 basis points plus the Term SOFR Adjustment (as defined in the amended loan agreement governing the Extended RBC Facility). As at September 30, 2023, available borrowings are C$14.6 million (US$10.8 million), of which no amounts have been drawn.

Further, the Company has a C$5.0 million equipment leasing facility in Canada (the “Canada Leasing Facility”) of which, as at September 30, 2023, C$4.4 million (US$3.3 million) has been drawn and C$3.8 million (US$2.8 million) has been repaid, and a US$14.0 million equipment leasing facility in the United States (the “U.S. Leasing Facility” and, together with the Canada Leasing Facility, the “Leasing Facilities”) of which, as at September 30, 2023, US$13.3 million has been drawn and US$5.2 million has been repaid, each with RBC, and one of its affiliates, which are available for equipment expenditures and certain equipment expenditures already incurred. The Canadian Leasing Facility and the U.S. Leasing Facility, respectively, have seven and five-year terms and bear interest at 4.25% and 5.59%. The U.S. Leasing Facility is amortized over a six-year term and extendible at the Company’s option for an additional year. In connection with the Company’s decision to permanently close its operations at its manufacturing facility in Rock Hill, South Carolina, the Company intends to early settle the U.S. Leasing Facility in the next twelve months.

The proceeds from the Offering are not expected to be used on a specific timeline. We intend to invest the net proceeds of this Offering which we do not immediately use, and such investments may include short-term

28

marketable investment grade securities. The actual amount that we spend in connection with each of the intended uses of proceeds will depend on a number of factors, including those referred to under “Risk Factors” in this prospectus and any accompanying prospectus supplement and the risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2022, our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2023, June 30, 2023 and September 30, 2023, and certain other documents incorporated by reference herein, which risk factors are incorporated herein by reference.

THE RIGHTS OFFERING

Reasons for the Rights Offering

We are conducting the Offering to raise capital for general corporate purposes, which may include investments in its business, funding potential future cash needs or operating losses, funding working capital and capital expenditure needs, or reductions to its outstanding indebtedness. The Company may seek to reduce its outstanding indebtedness by any one or more of several means, including open market or privately negotiated repurchases, tender offers, or redemptions of its Debentures, or through prepayments or repayment of necessary operating lease facilities and amounts outstanding under the Leasing Facilities. See “Use of Proceeds.”

The Rights

We are distributing, at no charge, to holders of our Common Shares as of the close of business on the Record Date, Rights to purchase up to an aggregate of            of our Common Shares in Canada and the United States. Each holder will receive one Right for each Common Share owned by such holder at the close of business on the Record Date. Each Right will entitle its holder to purchase          Common Shares at the Subscription Price of C$            per whole Common Share, exercisable for whole Common Shares only. As a result,             Rights are required to subscribe for one whole Common Share.

The Rights issued in the Offering are transferable and are expected to be listed on the TSX under the symbol “            .” The Common Shares issuable upon the exercise of the Rights will be listed on the TSX under the symbol “DRT” and quoted on the OTC under the symbol “DRTTF.”

The Rights issued pursuant to this Offering will be granted and exercisable beginning on or about                . The Rights will expire and will have no value if they are not exercised prior to the Expiration Time on the Expiration Date of this Offering. Computershare will serve as the subscription agent in the Offering.

All exercises of Rights are irrevocable once they are exercised. Our Board is making no recommendation regarding your exercise of the Rights. Holders who do not participate in the Offering will continue to own the same number of Common Shares. Holders who do not subscribe for the greatest number of shares permitted in the Offering will own a smaller percentage of the total Common Shares outstanding if and to the extent other holders fully exercise their Basic Subscription Privilege and Additional Subscription Privilege. Rights that are not exercised by the Expiration Date will expire and have no value.

If you exercise your Basic Subscription Privilege in full, you may also exercise an Additional Subscription Privilege to purchase additional Common Shares not issued under the Basic Subscription Privilege, subject to availability and pro rata allocation of shares among persons exercising the Additional Subscription Privilege.

Expiration of the Rights Offering and Extensions

The Rights may be exercised until the expiration of the Offering, which is             Eastern Time, on                .

Any Rights not exercised at or before the expiration of the Offering will be void and of no value. We will not be obligated to honor your exercise of Rights if the subscription agent receives the documents and payment of the Subscription Price relating to your exercise after this Offering expires, regardless of when you transmitted the documents.

Basic Subscription Privileges and Additional Subscription Privileges

The Basic Subscription Privilege of each Right will entitle you to purchase          Common Shares at the Subscription Price of C$            per whole Common Share, exercisable for whole Common Shares. You may not exercise your Rights to acquire less than one whole Common Share, meaning             Rights and payment of C$ is required to purchase one whole Common Share.

30

If you fully exercise your Basic Subscription Privilege (other than those Rights to acquire less than one whole Common Share, which cannot be exercised) and other shareholders do not fully exercise their Basic Subscription Privileges, you may also exercise an Additional Subscription Privilege to purchase additional Common Shares not issued under the Basic Subscription Privilege, subject to the availability and pro rata allocation of Common Shares among shareholders exercising this Additional Subscription Privilege. To the extent the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, then the available Common Shares will be prorated among those who properly exercised Additional Subscription Privileges based on the number of Common Shares that such holder subscribed for under the Basic Subscription Privilege against the total number of Common Shares subscribed for under the Basic Subscription Privilege by the holders properly exercising the Additional Subscription Privilege. If this pro rata allocation results in any shareholder receiving a greater number of Common Shares than the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, then such shareholder will be allocated only that number of Common Shares for which the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, and the remaining Common Shares will be allocated among all other shareholders exercising the Additional Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Common Shares have been allocated or all over-subscription exercises have been fulfilled, whichever occurs earlier.

No Fractional Shares of Common Shares

No fractional Common Shares will be issued. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the holder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be cancelled without any repayment of capital or other consideration therefor.

Regulatory Limitations

We will not offer or sell, or solicit any purchase of, Common Shares in any state or other jurisdiction in which this Offering is not permitted. We reserve the right to delay the commencement of this Offering in certain states or other jurisdictions if necessary to comply with local laws. We may elect not to offer Common Shares to residents of any state or other jurisdiction whose laws would require a change in this Offering in order to carry out this Offering in such state or jurisdiction.

All Rights issued to a shareholder of record who would, in our opinion, be required to obtain prior clearance or approval from any state, federal, or non-U.S. regulatory authority for the ownership or exercise of Rights or the ownership of additional Common Shares are null and void and may not be held or exercised by any such holder if, at such time, if applicable, such holder has not obtained such clearance or approval

Method of Subscription-Exercise of Rights

To exercise your Rights, you must complete and deliver Subscription Form to the subscription agent in the manner set out in the section entitled “Questions and Answers Relating to the Rights Offering—How to Exercise the Rights,” together with full payment for all the Rights you elect to exercise under the Basic Subscription Privilege and Additional Subscription Privilege, before the expiration of the Offering. You may deliver the documents and payments by mail or commercial carrier. If regular mail is used for this purpose, we recommend using registered mail, properly insured, with return receipt requested.

If you are a beneficial owner of Common Shares that are registered in the name of a broker, dealer, bank or other nominee, you should instruct your Registered Holder to exercise your Right on your behalf and deliver all required documents and payment before the expiration of the Offering. You should contact the Registered Holder of the rights as soon as possible as they may establish an earlier deadline for receiving subscription instructions. See “Questions and Answers Relating to the Rights Offering—How to Exercise the Rights— How does a shareholder that is not a Registered Holder participate in the Offering?” for more information.

Your payment of the Subscription Price must be made in Canadian dollars for the full number of Common Shares for which you are subscribing by certified check, bank draft or money order payable to the subscription agent. The subscription agent will accept payment only by certified cheque, bank draft or money order payable to the subscription agent.

Calculation of Rights Exercised

If you send a payment that is insufficient to purchase the number of Common Shares you requested, or if the number of Common Shares you requested is not specified in the Subscription Form, the payment received will be applied to exercise your Basic Subscription Privilege. Unless you have specified the number of Common Shares you wish to purchase upon exercise of your Additional Subscription Privilege, any payment in excess of that required to exercise your Basic Subscription Privilege will be refunded. If the payment exceeds the Subscription Price for the full exercise of the Basic Subscription Privilege and Additional Subscription Privilege (to the extent specified by you and subject to pro rata allocation), the excess will be refunded. You will not receive interest on any payments refunded to you under this Offering.

Your Funds Will Be Held by the Subscription Agent Until Shares of Our Common Shares are Delivered

The subscription agent will hold your payment of the Subscription Price in a segregated account with other payments received from other Rights holders until we deliver your Common Shares upon completion of this Offering, and after all pro rata allocations and adjustments have been completed and upon payment of the Subscription Price for such Common Shares.

Notice to Brokers and Nominees

If you are a broker, a trustee, or a depositary for securities who holds Common Shares for the account of others on                , the Record Date, you should notify the respective beneficial owners of such Common Shares

32

of this Offering as soon as possible to find out their intentions with respect to exercising their Rights. You should obtain instructions from the beneficial owner with respect to their Rights, as set forth in any provided instructions for your distribution to beneficial owners. If the beneficial owner so instructs, you should complete the appropriate Subscription Form and submit them to the subscription agent with the proper payment. If you hold Common Shares for the account(s) of more than one beneficial owner, you may exercise the number of Rights to which all such beneficial owners in the aggregate otherwise would have been entitled had they been direct Registered Holders of our Common Shares on the Record Date.

Beneficial Owners

If you hold your Common Shares in the name of a broker, bank, or other nominee (also known as a “beneficial holder”), then your broker, bank, or other nominee is the Registered Holder of the Common Shares you own. The Registered Holder must exercise the Rights on your behalf for the Common Shares you wish to purchase.

If you wish to participate in this Offering and purchase Common Shares, please promptly contact the Registered Holder of your Common Shares. You should follow the instructions provided to you by the Registered Holder of your Common Shares.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance of any subscription will be determined by the Company in its sole discretion, and any determination by the Company will be final and binding on the Company and its shareholders. The Company reserves the right to reject any subscription if it is not in proper form or if the acceptance thereof or the issuance of Common Shares pursuant thereto could be unlawful. The Company also reserves the right to waive any defect in respect of any particular subscription. Neither the Company nor the subscription agent is under any duty to give any notice of any defect or irregularity in any subscription, nor will they be liable for the failure to give any such notice. Any holder of Rights that fails to complete their subscription in accordance with the instructions contained in this prospectus prior to the expiration of the Offering will forfeit their Rights under the Basic Subscription Privilege and the Additional Subscription Privilege attaching to those Rights.

33

Material United States Federal Income Tax Considerations

We intend to take the position that the receipt of the Rights in this Offering, for U.S. federal income tax purposes, is non-taxable to U.S. Holders (as defined herein) of our Common Shares under Section 305(a) of the Code. For a detailed discussion, please see “Material United States Federal Income Tax Considerations.” U.S. Holders of our Common Shares are urged to consult their own tax advisors regarding the tax consequences of the Offering.

Questions about Exercising Rights

If you have any questions or require assistance regarding the method of exercising your Rights or requests for additional copies of this document, the Subscription Form or the Rights DRS Advice, you should contact the subscription agent or the Company at the address and telephone number set forth under “Questions and Answers Relating to the Rights Offering” included elsewhere in this prospectus.

Subscription Agent

Computershare is the subscription agent for the Offering. The subscription agent has been appointed to receive subscriptions and payments from holders of Rights and to perform services relating to the exercise and transfer of Rights.

Expenses

We will pay all fees charged by the subscription agent in connection with the Offering. You are responsible for paying any other commissions, fees, taxes or other expenses incurred in connection with the exercise of the Rights.

No Revocation or Change

Once you exercise your Rights, you may not revoke the exercise even if you later learn information that you consider to be unfavorable to the exercise of your Rights.

The public trading market price of our Common Shares may decline before the Rights expire. If you exercise your Rights and, afterwards, the market price of our Common Shares falls below the Subscription Price, then you will have committed to buy Common Shares in the Offering at a price that is higher than the market price. Moreover, we cannot assure you that you will ever be able to sell Common Shares that you purchased in the Offering at a price equal to or greater than the Subscription Price. You should not exercise your Rights unless you are certain that you wish to purchase additional shares of our Common Shares at a Subscription Price of C$             per Common Share.

Until the Common Shares are issued to you or your account at your broker, custodian bank or other nominee is credited upon expiration of the Offering, you may not be able to sell the Common Shares that you purchase in the Offering. We will credit your account at your broker, custodian bank or other nominee with our Common Shares, electronically in registered, book-entry form only on our records or on the records of our transfer agent, Computershare, that you purchased pursuant to your Basic Subscription and Additional Subscription Privileges as soon as practicable after the Offering has expired and all proration calculations, reductions, and additions contemplated by the terms of the Offering have been effected.

Resales and Purchases by Affiliates

The Rights and the Common Shares acquired by an affiliate of the Company in the Offering will not be transferable except in compliance with the resale limitations of Rule 144 promulgated under the Securities Act,

34

pursuant to another valid resale exemption from registration under the Securities Act, or further registration under the Securities Act. Rights distributed on Common Shares that are “restricted securities” under U.S. securities laws, will also be “restricted securities” and may not be transferred except in compliance with Rule 144, including its holding period (which will not be available during the Rights Offering).

Pursuant to the Company’s Insider Trading Policy, directors, officers and certain substantial shareholders of the Company will not be permitted to sell their Rights or purchase additional Rights.

Procedures for CDS and DTC Participants

We expect that the exercise of your Basic Subscription Privilege and your Additional Subscription Privilege may be made through the facilities of CDS or DTC. If your Rights are held of record through CDS or DTC or you are a shareholder holding your Common Shares in “street name” with CDS or DTC participants, you may exercise your Basic Subscription Privilege and your Additional Subscription Privilege by instructing CDS or DTC to transfer your Rights from your account to the account of the subscription agent, together with certification as to the aggregate number of Rights you are exercising and the number of Common Shares you are subscribing for under your Basic Subscription Privilege and your Additional Subscription Privilege, if any, and your Subscription Price payment for each Common Share that you subscribed for pursuant to your Basic Subscription Privilege and your Additional Subscription Privilege.

Subscription Price

The Subscription Price for each Common Share issuable pursuant to an exercise of Rights (whether under the Basic Subscription Privilege or the Additional Subscription Privilege) is C$            per whole Common Share, payable in cash. To be effective, any payment related to the exercise of a Right must clear prior to the expiration of the Offering.

On November 9, 2023, the closing price of the Common Shares on the TSX was C$0.49 and on the OTC was US$0.37.

Rights of Subscribers

You will have no rights as a holder with respect to Common Shares you subscribe for in the Offering until the Common Shares are issued to you or your account at your broker, dealer, custodian bank or other nominee is credited with such Common Shares.

Ineligible Holders

The Rights are being offered to holders of our Common Shares as of the close of business on the Record Date residing in the Eligible Jurisdictions. Approved Holders, being Ineligible Holders that are able to establish to the Company’s satisfaction, in its sole discretion, not later than                , that an offering to and subscription by such holder of Rights and Common Shares is lawful and in compliance with all securities and other laws applicable in the Eligible Jurisdictions and in the jurisdiction where such Ineligible Holder is resident and would not require that the Company file any document, take any proceeding, make any application, obtain any approval, give any notice or make any payment, in each case of any kind or nature whatsoever, including by delivering a representation letter in the form presented by the Company, will be eligible to receive Rights.

No Rights or Common Shares issuable upon exercise thereof are offered for sale, and no offers to purchase securities are solicited, in any jurisdiction that is not an Eligible Jurisdiction, or to or from Ineligible Holders.

Ineligible Holders will not receive a Rights DRS Advice and Subscription Form, but will be sent a letter advising (i) that their Rights will be held by the subscription agent, as agent for the benefit of all such Ineligible

35

Holders, and (ii) how Ineligible Holders might establish their ability to participate in the Offering and subscribe for Common Shares as an Approved Holder, failing which the subscription agent will attempt to sell the Rights for their benefit.

Rights Will Trade Publicly

The Rights are transferable and are expected to be listed on the TSX under the symbol “                .” The Rights are expected to trade until                , Eastern Time, on                . Rights holders, including those will hold Rights as a Registered Holder, are encouraged to contact their broker-dealer, bank, trustee, or other nominees for more information about trading of the Rights.

Our outstanding Common Shares are listed on the TSX under the symbol “DRT” and are quoted on the OTC under the symbol “DRTTF.”

Transfers and Sales of Rights

The Rights may be transferred (1) in whole, by endorsing the Rights DRS Advice for transfer in accordance with the instructions provided by the subscription agent or (2) in part, by delivering to the subscription agent a Rights DRS Advice properly endorsed for transfer, with instructions to register such portion of the Rights evidenced thereby in the name of the transferee and to issue a new Rights DRS Advice to the transferee evidencing such transferred Rights. In such event, a new Rights DRS Advice evidencing the balance of the Rights, if any, will be issued to the shareholder or, if the shareholder so instructs, to an additional transferee. The signature on the Rights DRS Advice must correspond to the name as written upon the face of the Rights DRS Advice, without alteration, enlargement, or any change. A medallion guarantee must be provided by an Eligible Guarantor Institution as that term is defined in Rule 17Ad-15 under the Exchange Act, subject to the standards and procedures adopted by us or the subscription agent.

The Rights are transferable and are expected to trade until                , Eastern Time, on                . Shareholders wishing to transfer all or a portion of their Rights should allow at least five business days prior to the Expiration Date of the Offering for: (i) the transfer instructions to be received and processed by the subscription agent; (ii) a new Rights DRS Advice to be issued and transmitted to the transferee or transferees with respect to transferred Rights and to the transferor with respect to retained Rights, if any; and (iii) the Rights evidenced by such new Rights DRS Advice to be exercised or sold by the recipients thereof. Neither we nor the subscription agent shall have any liability to a transferee or transferor of Rights if Rights DRS Advices are not received in time for exercise prior to the Expiration Date of the Offering or sale prior to the day immediately preceding the Expiration Date of the Offering.

Except for the fees charged by the subscription agent, which will be paid by us, all commissions, fees, and other expenses (including brokerage commissions and transfer taxes) incurred or charged in connection with the purchase, sale, or exercise of Rights will be for the account of the transferor of the Rights. None of those commissions, fees, or expenses will be paid by us or the subscription agent.

We anticipate that the Rights will be eligible for transfer through, and that the exercise of the Basic Subscription Privilege and the Additional Subscription Privilege may be effected through, the facilities of CDS or DTC. Holders of CDS or DTC exercised Rights may exercise the Additional Subscription Privilege in respect of such CDS or DTC exercised Rights by following the instructions issued by CDS or DTC for exercising the Additional Subscription Privilege before                , Eastern Time, on the Expiration Date of this Offering.

Subscription Funds; Return of Funds

The subscription agent will hold funds received in payment for Common Shares in a segregated account pending completion of this Offering. The subscription agent will hold this money until this Offering is completed or is withdrawn and canceled. If this Offering is withdrawn or canceled for any reason, all subscription payments received by the subscription agent will be promptly returned, without interest or deduction.

36

Transferability of Rights

The Rights issued in the Offering are transferable. The Rights are expected to be listed on the TSX under the symbol “                .”

Determination of Subscription Price

Each Right will entitle its holder to purchase          Common Shares at the Subscription Price of C$            per full share, exercisable for whole Common Shares only. The C$            Subscription Price per full Common Share was set by the Board in accordance with the TSX Company Manual, pursuant to which the Subscription Price must be at least a         % discount to the market price (as defined under TSX rules) of our Common Shares. In approving the Subscription Price, our Board considered, among other things, the following factors:

No Board Recommendation

Although our directors may potentially invest their own money in the Offering, they are not required to do so. Our Board is making no recommendation regarding your exercise of the Rights. You are urged to make your decision based on your own assessment of our business and the Offering. Please see “Risk Factors” for a discussion of some of the risks involved in acquiring the Offered Securities.

Interests of Our Executive Officers and Directors and Certain of Our Significant Shareholders

Our directors and executive officers who hold Common Shares as of the Record Date may elect to participate in the Offering with respect to Rights distributed in respect of their Common Shares. They have, however, no obligation to do so and DIRTT provides no assurances in this regard.

As of the date hereof 22NW and 726 hold 23,136,229 and 18,255,664 Common Shares, representing approximately 22.1% and 17.4% of the issued and outstanding Common Shares, respectively. Each of 22NW and 726 is expected to agree, pursuant to the Standby Purchase Agreement, in addition to the exercise of its Basic Subscription Privilege in full, to collectively purchase from the Company, at the Subscription Price, all Common Shares not issued under the Basic Subscription Privilege or Additional Subscription Privilege, or up to            Common Shares. See “Questions and Answers Relating to the Rights Offering—Standby Commitment.”

In addition, 22NW holds approximately C$18.9 million aggregate principal amount of the January Debentures and C$13.6 million aggregate principal amount of the December Debentures. To the extent the Company repurchases any Debentures held by 22NW with the proceeds of this Offering, including in a tender offer, 22NW may receive a portion of the proceeds from the Offering.

Common Shares Outstanding after the Rights Offering

As of November 9, 2023, we had 104,789,358 Common Shares outstanding. Assuming issuance of the maximum number of Common Shares under the Offering (            Common Shares), we will have            Common Shares outstanding after the Offering.

Dilution

Assuming issuance of the maximum number of Common Shares under the Offering (            Common Shares), and that you do not exercise any Rights and thus do not acquire any Common Shares pursuant to the Offering, your shareholdings will be diluted by approximately        %.

Effect of the Rights Offering on Holders of Stock Options, Performance Stock Units, Restricted Stock Units and Convertible Debentures

Holders of options to purchase our Common Shares will not receive Rights, unless they exercise their options for Common Shares prior to the Record Date. Similarly, holders of deferred share units, performance share units or restricted share units with respect to our Common Shares will not receive Rights, except to the extent their deferred share units, performance share units, restricted share units or such other awards are settled (to the extent applicable) for Common Shares prior to the Record Date.

Holders of our Debentures will not receive Rights. Pursuant to the base indenture, dated as of January 25, 2021, as supplemented by the supplemental indenture, dated January 25, 2021, or the second supplemental indenture, dated December 1, 2021, as applicable, the conversion price of the Debentures will be adjusted as a result of the Offering.

MARKET PRICE OF AND DIVIDENDS ON COMMON SHARES

Market Information

Our Common Shares are listed on the TSX under the ticker symbol “DRT.” Our Common Shares are quoted on the OTC under the ticker symbol “DRTTF.”

Holders of Record

As of November 9, 2023, there were 104,789,358 Common Shares outstanding and 166 shareholders of record. The actual number of shareholders is greater than this number of record holders and includes shareholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include shareholders whose Common Shares may be held in trust or by other entities.

Dividends

We have not declared or paid any cash dividends on our Common Shares to date. The declaration and payment of dividends is at the discretion of the Board, taking into account (i) our earnings, capital requirements and financial condition, (ii) restrictions on our ability to pay dividends under our credit agreements, and (iii) such other factors as the Board considers relevant. Our credit agreements generally limit our ability to pay any dividends or make any other distribution on our outstanding Common Shares. If and when our Board declares cash dividends on our Common Shares, such dividends may be declared and paid in either U.S. dollars or Canadian dollars.

RELATED PARTY TRANSACTIONS

Other than the director and executive compensation arrangements discussed in our Definitive Proxy Statement on Schedule 14A, filed on April 14, 2023, related party transactions described in the documents incorporated by reference to the prospectus, and as set out below, there have not been any transactions since January 1, 2023, to which the Company has been or will be a participant, in which the amount involved exceeded or will exceed US$120,000, and in which any of our directors, executive officers or holders of more than 5% of any class of our voting shares, or any member of the immediate family of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.

Standby Purchase Agreement

The Company anticipates that it will enter into the Standby Purchase Agreement with the Standby Purchasers prior to the commencement of the Offering. Pursuant to the Standby Purchase Agreement, 22NW will exercise its Basic Subscription Privilege in full and, accordingly, will purchase a minimum of            Common Shares for aggregate gross proceeds to the Company of C$            . To the extent there are Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege, 22NW will purchase up to            Common Shares for aggregate gross proceeds to the Company of C$            .

Pursuant to the Standby Purchase Agreement, 726 will exercise its Basic Subscription Privilege in full and, accordingly, will purchase a minimum of            Common Shares for aggregate gross proceeds to the Company of C$            . To the extent there are Common Shares not subscribed for by other holders under the Basic Subscription Privilege or Additional Subscription Privilege, 726 will purchase up to            Common Shares for aggregate gross proceeds to the Company of C$            .

39

Aron English is a director of the Company and founder and portfolio manager of 22NW. Shaun Noll is a director of the Company and President and Chief Investment Officer of 726. Each of 22NW and 726 own more than 5% of our outstanding Common Shares and are directors by deputization of the Company.

Purchase of Debentures by 22NW

On September 19, 2023, 22NW purchased C$18.9 million principal amount of the January Debentures and C$13.6 million principal amount of the December Debentures, representing an aggregate amount of principal outstanding of C$32.5 million. The January Debentures accrue interest at the rate of 6.00% per annum payable semi-annually in arrears on the last day of January and July of each year commencing on July 31, 2021 until January 31, 2026. The December Debentures accrue interest at the rate of 6.25% per annum payable semi-annually in arrears on the last day of June and December of each year commencing on June 30, 2022 until December 31, 2026.

The transactions were solely between 22NW and third parties, and there was no involvement in the transactions by the Company. As of the date of this prospectus, 22NW has not received any interest payments on the Debentures, but C$189,668 and C$214,845 in interest has accrued on the January Debentures and December Debentures held by 22NW, respectively, in accordance with the terms of the base indenture, dated as of January 25, 2021, as supplemented by the supplemental indenture, dated January 25, 2021, or the second supplemental indenture, dated December 1, 2021, as applicable.

Related Party Transactions Policy

The Company has adopted a written Related Party Transactions Policy, which provides that our Corporate Governance and Compensation Committee is responsible for reviewing “related party transactions,” which are transactions, arrangements or relationships (or any series of similar transactions, arrangements or relationships), to which we are a party, in which the aggregate amount involved exceeds or may be expected to exceed US$120,000 and in which a related person has, had or will have a direct or indirect material interest. For purposes of this policy, a “related person” is defined to include a director, executive officer, nominee for director and greater than 5% beneficial owner of our voting securities, in each case since the beginning of the most recently completed year, and any of their immediate family members. In determining whether to approve or ratify any such transaction, the Corporate Governance and Compensation Committee will take into account, among other factors it deems appropriate, (i) whether the transaction is on terms comparable to the terms generally available to unaffiliated third parties under the same or similar circumstances and (ii) the extent of the related party’s interest in the transaction.

It is anticipated that the entry into the Standby Purchase Agreement will be approved by a special committee of the Board comprising independent and disinterested directors.

DESCRIPTION OF CAPITAL STOCK

The following summary describes our capital stock and the material provisions of our amended and restated articles of amalgamation (our “articles of amalgamation”) and our amended and restated by-laws (our “by-laws”), and provisions of applicable law. Because the following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to our article of amalgamation and our by-laws, copies of which have been filed as exhibits to the registration statement of which this prospectus is a part, and to provisions of applicable law, including the Business Corporations Act (Alberta) (the “ABCA”).

Authorized Shares and Capital Structure

Under our articles of amalgamation, we have the authority to issue: (i) an unlimited number of Common Shares, and (ii) an unlimited number of preferred shares issuable in one or more series having the designation, rights, privileges and conditions attaching to each series of such shares as the directors may fix by resolutions from time to time before the issuance thereof, and each series to consist of such number of shares as may, before the issuance thereof, be determined by resolution of the directors, except that the directors may not issue any preferred shares if by doing so the aggregate number of preferred shares that would then be issued and outstanding would exceed 20% of the aggregate number of Common Shares then issued and outstanding. Under Alberta law, there is no franchise tax on our authorized share capital. As of November 9, 2023, we had 104,789,358 Common Shares outstanding and no preferred shares outstanding.

Common Shares. The holders of Common Shares are entitled to notice of and to attend all meetings of shareholders (except meetings at which only holders of a specified class of shares are entitled to vote) and are entitled to one vote per Common Share. Holders of Common Shares are not entitled to cumulative voting rights in respect of the election of directors or otherwise. There are no restrictions on foreign holders voting our Common Shares. Holders of Common Shares are entitled to receive, if, as and when declared by the Board, such dividends as may be declared thereon by the Board from time to time; provided that the Company may declare dividends on any class of shares to the exclusion of any other class without being obliged to declare any dividends on the Common Shares. In the event of dissolution, subject to the rights, privileges, restrictions and conditions attaching to any other class of shares of the Company, our holders of Common Shares are entitled to share equally on a pro rata basis in the remaining property of the Company.

Our outstanding Common Shares are fully paid and non-assessable.

Preferred Shares. We do not have any preferred shares currently outstanding. Pursuant to our articles of amalgamation, our Board has the authority, without further action by our shareholders, to issue from time to time preferred shares in one or more series. Our Board may by resolution fix from time to time before the issue thereof the designation, rights, privileges, restrictions and conditions attaching to each series of the preferred shares, including dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund terms, and the number of shares constituting any series or the designation of any series. The issuance of preferred shares could have the effect of restricting dividends on our Common Shares, diluting the voting power of our Common Shares, impairing the liquidation rights of our Common Shares, or delaying, deterring or preventing a change in control. Such issuance could have the effect of decreasing the market price of our Common Shares. Any preferred shares so issued may rank senior to our Common Shares with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or both. Pursuant to our articles of amalgamation, the Board may not issue any preferred shares if by doing so the aggregate number of preferred shares that would then be issued and outstanding would exceed by 20% of the aggregate number of Common Shares then issued and outstanding. We currently have no plans to issue any preferred shares.

Shareholder Approval; Vote on Extraordinary Corporate Transactions. Under the ABCA, certain extraordinary corporate actions, such as a name change, amalgamations (other than with certain affiliated

41

corporations), continuances to another jurisdiction and sales, leases or exchanges of all, or substantially all, of the property of a corporation (other than in the ordinary course of business), and other extraordinary corporate actions such as liquidations, dissolutions and arrangements (if ordered by a court), are required to be approved by a “special resolution” of shareholders.

A “special resolution” is a resolution (i) passed by a majority of not less than two-thirds of the votes cast by the shareholders who voted in respect of the resolution, or (ii) signed by all shareholders entitled to vote on the resolution. In specified cases, a special resolution to approve an extraordinary corporate action is required to be approved separately by the holders of a class or series of shares, including in certain cases a class or series of shares not otherwise carrying voting rights.

Amendments to the Governing Documents. Under the ABCA, amendments to the articles of a corporation generally require approval by special resolution of shareholders. If the proposed amendment would affect a particular class of shares in certain specified ways, the holders of shares of that class are entitled to vote separately as a class on the proposed amendment, whether or not the shares otherwise carry the right to vote.

The ABCA allows the directors, by resolution, to make, amend or repeal any by-laws that regulate the business or affairs of the corporation. When directors make, amend or repeal a by-law, they are required, under the ABCA, to submit the change to shareholders at the next meeting of shareholders. Shareholders may confirm, reject or amend the by-law, the amendment or the repeal with the approval of a majority of the votes cast by shareholders who voted on the resolution. If a by-law, or an amendment or a repeal of a by-law, is rejected by the shareholders, or if the directors do not submit a by-law, or an amendment or a repeal of a by-law, to the shareholders, the by-law, amendment or repeal ceases to be effective and no subsequent resolution of the directors to make, amend or repeal a by-law having substantially the same purpose or effect is effective until it is confirmed or confirmed as amended by the shareholders.

Quorum of Shareholders. The ABCA provides that, unless the by-laws provide otherwise, a quorum of shareholders is present at a meeting of shareholders (irrespective of the number of persons actually present at the meeting) if holders of a majority of the shares entitled to vote at the meeting are present in person or represented by proxy. Our by-laws provide that a quorum is present if there are at least two persons present in person, each being a shareholder entitled to vote thereat or a duly appointed proxy or representative for an absent shareholder so entitled, and representing in the aggregate at least 33-1/3% of our outstanding shares carrying voting rights at the meeting of shareholders.

Calling Meetings. The ABCA provides that the directors shall call an annual meeting of shareholders not later than 15 months after the last preceding annual meeting, and may at any time call a special meeting of shareholders. Pursuant to our articles of amalgamation and our by-laws, meetings of shareholders may be held inside or outside Alberta at such place as may be determined by the Board from time to time. The Registered Holders or beneficial owners (as defined in the ABCA) of not less than 5% of the issued shares of a corporation that carry the right to vote at a meeting sought to be held may requisition the directors to call a meeting of shareholders for the purposes stated in the requisition, but the beneficial owners of shares do not thereby acquire the direct right to vote at the meeting that is the subject of the requisition.

Shareholder Consent in Lieu of Meeting. Under the ABCA, a resolution in writing signed by all of the shareholders entitled to vote on that resolution is as valid as if it had been passed at a meeting of shareholders.

Director Election, Qualification and Number. The ABCA provides for the election of directors by a plurality vote (i.e., shareholders may either vote “for” or “withhold” from voting for a director) at an annual meeting of shareholders. The ABCA states that a corporation shall have one or more directors but a reporting issuer whose shares are held by more than one person shall have not fewer than three directors, at least two of whom are not officers or employees of the corporation or its affiliates.

42

Pursuant to the majority voting policy of the Company (the “Majority Voting Policy”), if any director nominee receives a number of votes “withheld” from his or her election equal to or greater than votes “for” such election, such nominee should submit his or her offer of resignation to the lead director or Chair of the Board. The Nominating and Governance Committee will review such resignation offer and make a recommendation to the Board of whether or not to accept it. The Nominating and Governance Committee is expected to recommend acceptance of the resignation offer to the Board, and the Board is expected to accept such recommendation and resignation offer, except where exceptional circumstances would warrant the director nominee continuing to serve on the Board. The director nominee will not participate in any deliberations of the Nominating and Governance Committee or the Board with respect to his or her resignation offer. Within 90 days of receiving the resignation offer, the Board will make a decision and issue a press release announcing whether it has accepted or rejected the director nominee’s resignation. The resignation will be effective only when accepted by the Board. The Majority Voting Policy of the Company does not apply to contested elections in which the number of director nominees for election is greater than the number of director positions on the Board.

Vacancies on Board of Directors. Under the ABCA, a vacancy among the directors created by the removal of a director may be filled at the meeting of shareholders at which the director is removed. The ABCA also allows a vacancy on the board to be filled by a quorum of directors, except when the vacancy is a result of an increase in the number or minimum number of directors or a failure to elect the number or minimum number of directors required by the articles of a corporation. In addition, the ABCA and our articles of amalgamation provide that the directors may, between annual general meetings, appoint one or more additional directors of the corporation to serve until the next annual general meeting, so long as the number of additional directors shall not at any time exceed one-third of the number of directors who held office at the expiration of the last annual meeting of the corporation.

Removal of Directors; Terms of Directors. Under the ABCA, provided that the articles of a corporation do not provide for cumulative voting, shareholders of the corporation may, by ordinary resolution passed at a special meeting, remove any director or directors from office. If holders of a class or series of shares have the exclusive right to elect one or more directors, a director elected by them may only be removed by an “ordinary resolution” at a meeting of the shareholders of that class or series.

An “ordinary resolution” means a resolution (i) passed by a majority of the votes cast by the shareholders who voted in respect of that resolution, or (ii) signed by all the shareholders entitled to vote on that resolution.

Fiduciary Duty of Directors. Directors of a corporation existing under the ABCA have fiduciary obligations to the corporation. The ABCA requires directors and officers of an Alberta corporation, in exercising their powers and discharging their duties, to act honestly and in good faith with a view to the best interests of the corporation and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

Indemnification of Officers and Directors. Under the ABCA and pursuant to our by-laws, we will indemnify present and former directors and officers against all costs, charges and expenses, including any amount paid to settle an action or satisfy a judgment that is reasonably incurred by the person in respect of any civil, criminal or administrative action or proceeding to which the person is made a party because he or she acted as a director or officer of the corporation. In order to qualify for indemnification such directors or officers must:

We carry liability insurance for our and our subsidiary’s officers and directors, as permitted by our by-laws and the ABCA.

43

The ABCA also provides that such persons are entitled to indemnity from the corporation in respect of all costs, charges and expenses reasonably incurred in connection with the defense of any such proceeding if the person: (i) was substantially successful on the merits in the person’s defense of the action or proceeding; (ii) otherwise meets the qualifications for indemnity described above; and (iii) is fairly and reasonably entitled to indemnity.

Dissent or Dissenters’ Appraisal Rights. The ABCA provides that shareholders of a corporation are entitled to exercise dissent rights and be paid by the corporation the fair value of their shares in connection with specified matters, including, among others:

However, a shareholder is not entitled to dissent if an amendment to the articles of the corporation is effected by a court order approving a reorganization or by a court order made in connection with an action for an oppression remedy.

Oppression Remedy. The ABCA provides an oppression remedy that enables a court to make any order, whether interim or final, to rectify matters that are oppressive or unfairly prejudicial to or that unfairly disregard the interests of any security holder, creditor, director or officer of the corporation if an application is made to a court by a “complainant.”

A “complainant” with respect to a corporation means any of the following:

The oppression remedy provides the court with very broad and flexible powers to intervene in corporate affairs to protect shareholders and other complainants. While conduct that is in breach of fiduciary duties of directors or that is contrary to the legal right of a complainant will normally trigger the court’s discretion under the oppression remedy, the exercise of that discretion does not depend on a finding of a breach of legal rights.

Derivative Actions. Under the ABCA, a complainant may also apply to the court for permission to bring an action in the name of, and on behalf of, the corporation or any of its subsidiaries, or to intervene in an existing action to which the corporation or its subsidiary is a party, for the purpose of prosecuting, defending or discontinuing the action on the corporation’s behalf or on behalf of its subsidiary. Under the ABCA, no action may be brought and no intervention in an action may be made unless a court is satisfied that:

44

Under the ABCA, the court in a derivative action may make any order it sees fit, including an order: (i) authorizing the complainant to control the conduct of the lawsuit, (ii) directing payments to former and present security holders, and (iii) requiring the corporation to pay reasonable legal fees incurred by the complainant.

Examination of Corporate Records. Under the ABCA, upon payment of a prescribed fee, a person is entitled, during usual business hours, to examine certain corporate records, such as the securities register and a list of shareholders, and to make copies of or extracts from such documents.

Advance Notice for Shareholder Proposals and Director Nominations. The ABCA permits certain eligible shareholders and beneficial owners of shares to submit shareholder proposals to the Company, which proposals may be included in the Company’s management information circular and proxy statement. To be considered for inclusion in the management information circular and proxy statement for the annual meeting of shareholders of the Company, any such shareholder proposal under the ABCA must be submitted to the Company at least 90 days before the anniversary date of the last annual meeting of shareholders.

Additionally, our current by-laws include advance notice provisions. These provisions set deadlines for a certain number of days before a shareholders’ meeting for a shareholder to notify the Company of his, her or its intention to nominate one or more directors, and explains the information that must be included with the notice for it to be valid. Such shareholder nominations generally must be provided to the Company (i) in the case of an annual meeting of shareholders, not less than 30 days before the date of such annual meeting and (ii) in the case of a special meeting of shareholders, no later than the close of business on the 15th day after the date on which the first public filing or announcement of the date of such special meeting was made; except that, in either instance, if notice-and-access is used for delivery of proxy related materials and the date on which the first public filing or announcement of the date of such meeting was made in respect of such meeting is not less than 50 days prior to the date of the applicable meeting, the notice must be received not less than 40 days before the date of the applicable meeting. The notice must set forth specific information, as further described in our by-laws. This requirement is in addition to those set forth in the regulations adopted by the SEC under the Securities Exchange Act of 1934 or any applicable laws or regulations of Canada, including the ABCA.

Potential Anti-Takeover Effect. Certain of the foregoing provisions of DIRTT’s articles of amalgamation and by-laws, together with the provisions of the ABCA as summarized below, could have the effect of delaying, deferring or preventing a change in control or the removal of existing management, of deterring potential acquirors from making an offer to DIRTT’s shareholders and of limiting any opportunity to realize premiums over prevailing market prices for DIRTT’s Common Shares in connection therewith. This could be the case notwithstanding that a majority of DIRTT’s shareholders might benefit from such a change in control or offer.

Other Important Ownership and Exchange Controls

There is no limitation imposed by applicable Alberta law or by our articles of amalgamation on the right of a non-resident to hold or vote our Common Shares, other than as discussed herein.

Competition Act. Limitations on the ability to acquire and hold our Common Shares may be imposed by the Competition Act (Canada) (the “Competition Act”). This legislation permits the Commissioner of Competition (the “Commissioner”) to review any acquisition or establishment, directly or indirectly, including through the acquisition of shares, of control over or of a significant interest in us. This legislation grants the Commissioner jurisdiction, for up to one year after the acquisition has been substantially completed, to seek a remedial order, including an order to prohibit the acquisition or require divestitures, from the Canadian Competition Tribunal on the basis that the acquisition would, or would be likely to, substantially prevent or lessen competition.

45

This legislation also requires any person who intends to acquire more than 20% of our voting shares to file a notification with the Canadian Competition Bureau if certain financial thresholds are exceeded. Where a person (and such person’s affiliates) already holds, in the aggregate, more than 20% of all of our voting shares, a notification must be filed if the acquisition of additional shares would bring such person’s (and its affiliates) holdings to over 50% if certain financial thresholds are exceeded. Where a notification is required, unless an exemption is available, the Competition Act prohibits completion of the acquisition until the expiration of the applicable statutory waiting period, unless compliance with the waiting period has been waived or the Commissioner has issued an advance ruling certificate under section 102 of the Competition Act. The Commissioner’s review of a notifiable transaction for substantive competition law considerations may take longer than the statutory waiting period.

Investment Canada Act. (“ICA”). The ICA requires any person that is non-Canadian (as defined in the ICA) who acquires “control” (as defined in the ICA) of an existing Canadian business to file a pre-closing application for review with Innovation, Science and Economic Development Canada, where prescribed financial thresholds are exceeded. The ICA generally prohibits the implementation of a reviewable transaction unless, after review, the relevant minister is satisfied that the acquisition is likely to be of a net benefit to Canada. Where the acquisition of control of a Canadian business by a non-Canadian does not meet the prescribed review thresholds, the investor is required, subject to certain exceptions, to file a notification no later than 30 days after the completion of the transaction.

Under the ICA, an investment in our Common Shares by a non-Canadian that is a private sector “trade agreement investor,” including a United States investor, would be reviewable only if it were an investment to acquire control of our business pursuant to the ICA and the enterprise value of our business (as determined pursuant to the ICA and the regulations thereto) were to be equal to or greater than C$1.931 billion. An investment in our Common Shares by a non-Canadian that is a private sector World Trade Organization member country investor would be reviewable only if the enterprise value of our business (as determined pursuant to the ICA and the regulations thereto) were to be equal to or greater than C$1.287 billion. Different rules apply if the non-Canadian investor is a “state owned enterprise” (as determined pursuant to the ICA and the regulations thereto). The ICA contains various rules to determine whether an investment is an acquisition of control of a Canadian business. For example, for purposes of determining whether an investor acquires control of a corporation by acquiring its shares, the following general rules apply, subject to certain exceptions: (i) the acquisition of a majority of the voting shares of a corporation is deemed to be acquisition of control of that corporation, (ii) the acquisition of less than a majority, but more than one-third, of the voting shares of a corporation is presumed to be acquisition of control of that corporation unless it can be established that, on the acquisition, the corporation is not controlled in fact by the acquirer through the ownership of voting shares, and (iii) the acquisition of less than one-third of the voting shares of a corporation is deemed not to be acquisition of control of that corporation.

Under the national security regime in the ICA, the Canadian federal government may undertake a discretionary review of a broader range of investments by a non-Canadian to determine whether such investments by a non-Canadian could be “injurious to national security”. No financial threshold applies to a national security review. Review on national security grounds is at the discretion of the Canadian federal government and may occur on a pre- or post-closing basis.

There are limited exemptions to a review of an acquisition of our Common Shares under the ICA, subject to the Canadian Government’s discretion to conduct a national security review, including, generally: the acquisition of our Common Shares by a person in the ordinary course of that person’s business as a trader or dealer in securities; and the acquisition of control of our business in connection with the realization of security granted for a loan or other financial assistance and not for any purpose related to the provisions of the ICA.

Other. There is no law, governmental decree or regulation in Alberta that restricts the export or import of capital or that would affect the remittance of dividends (if any) or other payments by us to non-resident holders of our Common Shares, other than withholding and other tax requirements.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the principal Canadian federal income tax considerations generally applicable under the Income Tax Act (Canada) and the regulations thereunder (collectively, the “Tax Act”) to a holder of Common Shares who receives Rights under this Offering including any such holder who exercises the Rights received to acquire Common Shares. This summary is only applicable to a holder who, at all relevant times, for the purposes of the Tax Act and the Canada – United States Income Tax Convention (the “Convention”): (i) is not, and is not deemed to be, a resident of Canada, (ii) holds the Rights and will hold any Common Shares acquired pursuant to the exercise of Rights as capital property, (iii) deals at arm’s length, and is not affiliated, with the Company or any Standby Purchaser, (iv) does not use or hold the Rights or Common Shares in the course of carrying on a business in Canada, and (v) is resident solely in the United States, is a “qualifying person” within the meaning of the Convention, and is entitled to full benefits under the Convention (each, a “U.S. Resident Holder”).

This summary does not apply to a holder of Common Shares: (i) that is a “financial institution” for purposes of the mark to market rules contained in the Tax Act; (ii) that is a partnership; (iii) an interest in which is or would constitute a “tax shelter investment” as defined in the Tax Act; (iv) that is a “specified financial institution” as defined in the Tax Act; (v) that reports its “Canadian tax results,” as defined in the Tax Act, in a currency other than Canadian currency; (vi) that has entered into, or will enter into, a “synthetic disposition arrangement” or a “derivative forward agreement,” as those terms are defined in the Tax Act, with respect to Rights or Common Shares; or (vii) that will receive dividends on any Common Shares under or as part of a “dividend rental arrangement,” as defined in the Tax Act. Such holders should consult their own tax advisors with respect to the Rights or Common Shares. Special considerations, which are not discussed in this summary, may apply to a U.S. Resident Holder that is an insurer that carries on an insurance business in Canada and elsewhere, that is an “authorized foreign bank,” as defined in the Tax Act, or that is a holder of special status. Such U.S. Resident Holders should consult their own advisors.

Generally, the Rights and the Common Shares will be considered to be capital property to a holder provided the holder does not hold the Rights or the Common Shares, as the case may be, in the course of carrying on a business of trading or dealing in securities and has not acquired such securities in one or more transactions considered to be an adventure or concern in the nature of trade, all within the meaning of the Tax Act.

This summary is based upon the current provisions of the Tax Act, the Convention, and the administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”) and assumes that the Tax Proposals will be enacted in the form proposed, although no assurance can be given that the Tax Proposals will be enacted in their current form or at all. This summary does not otherwise take into account any changes in law or in the administrative policies or assessing practices of the CRA, whether by legislative, governmental or judicial decision or action, nor does it take into account or consider any provincial, territorial or foreign income tax considerations, which considerations may differ significantly from the Canadian federal income tax considerations described herein.

This summary is of a general nature only, and is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular U.S. Resident Holder or prospective U.S. Resident Holder. Consequently, U.S. Resident Holders should consult their own tax advisors for advice with respect to the tax considerations applicable to them, having regard to their particular circumstances.

Currency

For the purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of Rights and Common Shares (including dividends received or deemed to have been received, adjusted cost base and proceeds

50

of disposition) must be determined in Canadian dollars using the rate of exchange quoted by the Bank of Canada on the day the amount first arose, or such other rate of exchange as is acceptable to the CRA.

Receipt of Rights

The issuance of Rights to a U.S. Resident Holder will not be subject to Canadian withholding tax and no other tax will be payable under the Tax Act by a U.S. Resident Holder in respect of the receipt of Rights pursuant to the Offering. The cost of Rights received under the Offering will be nil.

Exercise of Rights

The exercise of Rights will not constitute a disposition of property for purposes of the Tax Act and, consequently, no gain or loss will be realized by a U.S. Resident Holder upon the exercise of Rights. Common Shares acquired by a U.S. Resident Holder upon the exercise of Rights will have a cost to the U.S. Resident Holder equal to the aggregate of the Subscription Price paid. The adjusted cost base to the holder of a Common Share acquired pursuant to the exercise of Rights will be determined by averaging the cost of such share with the adjusted cost base of all Common Shares owned by the U.S. Resident Holder as capital property immediately before the acquisition (if any).

Expiry of Rights

A U.S. Resident Holder will not be subject to tax under the Tax Act in respect of the expiry or termination of an unexercised Right.

Dispositions of Rights

A U.S. Resident Holder will generally not be subject to tax under the Tax Act on any capital gain realized on a disposition of Rights unless the Rights constitute “taxable Canadian property,” within the meaning of the Tax Act, of the U.S. Resident Holder at the time of the disposition and the U.S. Resident Holder is not entitled to relief under the Convention. Generally, the Rights are not expected to constitute “taxable Canadian property” of a U.S. Resident Holder unless the Common Shares would constitute “taxable Canadian property” to the U.S. Resident Holder. The circumstances under which the Common Shares which may be acquired pursuant to the Rights would be “taxable Canadian property” to a U.S. Resident Holder are described below under “Dispositions of Common Shares.” U.S. Resident Holders whose Rights constitute “taxable Canadian property” should consult their own tax advisors for advice having regard to their particular circumstances.

Dividends on Common Shares

Dividends paid or credited, or deemed to be paid or credited, to a non-resident of Canada on the Common Shares will be subject to Canadian withholding tax under the Tax Act at the rate of 25% of the gross amount of the dividend. Such rate is generally reduced under the Convention to 15% if the beneficial owner of such dividend is a U.S. Resident Holder. The rate of withholding tax is further reduced to 5% if the beneficial owner of such dividend is a U.S. Resident Holder that is a company that owns, directly or indirectly, at least 10% of the voting stock of the Company. U.S. Resident Holders who may be eligible for a reduced rate of withholding tax on dividends pursuant to the Convention should consult with their own tax advisors with respect to taking all appropriate steps in this regard.

Dispositions of Common Shares

A U.S. Resident Holder who disposes or is deemed to dispose of a Common Share will not be subject to tax under the Tax Act on any capital gain realized on such disposition, unless the Common Share constitutes “taxable Canadian property,” within the meaning of the Tax Act, of the U.S. Resident Holder at the time of the

51

disposition and the U.S. Resident Holder is not entitled to relief under the Convention. Generally, as long as the Common Shares are listed on a “designated stock exchange,” within the meaning of the Tax Act (which includes the TSX) at the time of the disposition, the Common Shares of a particular U.S. Resident Holder will not be “taxable Canadian property” of such U.S. Resident Holder, unless, at any time during the 60-month period immediately preceding that time: (a) the U.S. Resident Holder, persons with which the U.S. Resident Holder does not deal at arm’s length, partnerships whose members include, either directly or indirectly through one or more partnerships, the U.S. Resident Holder or persons who do not deal at arm’s length with the U.S. Resident Holder, or any combination of them, owned 25% or more of the issued shares of any class or series of the share capital of the Company, and (b) more than 50% of the fair market value of the Common Shares was derived, directly or indirectly, from one or any combination of real or immovable property situated in Canada, “Canadian resource properties,” “timber resource properties,” each as defined in the Tax Act, and options in respect of or interests in, or for civil law rights in, any such property (whether or not such property exists). The Tax Act may also deem Common Shares to be taxable Canadian property to a U.S. Resident Holder in certain circumstances.

In the event that, the Common Shares of a U.S. Resident Holder constitute taxable Canadian property to such U.S. Resident Holder, the U.S. Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized by such U.S. Resident Holder on a disposition of common shares if the common shares are “treaty-protected property” of the U.S. Resident Holder at the time of the disposition. The Common Shares of a U.S. Resident Holder will generally constitute “treaty-protected property” for purposes of the Tax Act unless the value of the common shares is derived, at the time of the disposition, principally from real property situated in Canada. In the event that a common share is “taxable Canadian property”, within the meaning of the Tax Act, to a U.S. Resident Holder at the time of disposition, such U.S. Resident Holder should consult its own tax advisor as to the Canadian federal income tax consequences of the disposition, including any steps to be taken to benefit from relief from Canadian taxation under the Convention.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes the material U.S. federal income tax considerations to U.S. Holders (as defined herein) of the receipt, ownership, exercise, lapse and disposition of the Rights issued pursuant to the Offering and the ownership and disposition of our Common Shares received upon the exercise of such Rights. The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and U.S. Treasury regulations promulgated thereunder, judicial authority and administrative interpretations, and the Canada-United States Income Tax Convention (1980), as amended (the “Canada-US Tax Treaty”), all as of the date hereof, and all of which are subject to change, possibly with retroactive effect, or are subject to differing interpretations. We cannot assure you that the U.S. Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of receiving, owning, exercising, allowing the lapse of or disposing of the Rights or owning or disposing of our Common Shares received upon the exercise of such Rights.

This discussion is limited to U.S. Holders who receive the Rights in this Offering and who hold the Rights or our Common Shares received upon exercise of such Rights as capital assets (generally, property held for investment). This discussion does not address any U.S. federal tax considerations other than U.S. federal income tax considerations (such as U.S. federal estate and gift tax considerations and the Medicare tax on certain investment income), or the tax considerations arising under the laws of any state, local, non-U.S. or other jurisdiction or any income tax treaty (other than the Canada-US Tax Treaty). This discussion does not address any U.S. federal income tax considerations related to or resulting from payments in connection with a repurchase, tender offer or redemption of the Convertible Securities (as defined herein). In addition, this discussion does not address all U.S. federal income tax considerations that may be important to a particular holder in light of the holder’s particular circumstances, or to certain categories of holders that may be subject to special rules, such as:

As used herein, the term “U.S. Holder” means a beneficial owner of the Rights or Common Shares received upon exercise of a Right that is, for U.S. federal income tax purposes:

53

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the Rights or Common Shares received upon exercise of a Right, the U.S. federal income tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership and upon certain determinations made at the partner level. Partnerships that receive the Rights or Common Shares received upon exercise of such Rights and partners therein should consult their own tax advisors with respect to the U.S. federal income tax consequences of receiving, owning, exercising, allowing the lapse of and disposing of the Rights and owning and disposing of Common Shares received upon exercise of such Rights.

INVESTORS RECEIVING THE RIGHTS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSIDERATIONS OF THE RECEIPT, OWNERSHIP, EXERCISE, LAPSE AND DISPOSITION OF THE RIGHTS AND THE OWNERSHIP AND DISPOSITION OF COMMON SHARES RECEIVED UPON EXERCISE OF SUCH RIGHTS UNDER OTHER U.S. FEDERAL TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Receipt, Ownership, Exercise, Lapse and Disposition of the Rights

U.S. Federal Income Tax Characterization of the Receipt of the Rights

Although the authorities governing the Offering are very complex and do not directly address the consequences of certain aspects of the Offering, it is expected, and the Company intends to take the position, that a U.S. Holder’s receipt of Rights pursuant to the Offering with respect to such U.S. Holder’s Common Shares should be a non-taxable distribution with respect to such Common Shares for U.S. federal income tax purposes.

As a general rule under Section 305(a) of the Code, the distribution of stock (including rights to acquire stock) by a corporation to its common shareholders with respect to their stock is non-taxable to such shareholders. However, Section 305(b) of the Code contains a number of exceptions to the general rule set forth in Section 305(a). If a distribution of stock or rights to acquire stock falls within one of these exceptions, the distribution may be taxable to the shareholders in the manner set forth below.

Section 305(b)(2) provides that Section 305(a) does not apply to a “disproportionate distribution.” A disproportionate distribution is a distribution (or a series of distributions) that results in (i) the receipt of property by some shareholders and (ii) an increase in the proportionate interest of other shareholders in the assets or earnings and profits of the distributing corporation. For such purposes, the term “property” means money, securities and any other property, but the term does not include stock in the corporation making the distribution or rights to acquire such stock. In order for the distribution of property to meet the requirements of Section 305(b)(2), such distribution must be made to a shareholder in his capacity as a shareholder. Under Section 305(d)(2), the payment of interest to a holder of a convertible debenture is treated as a distribution of property to a shareholder for purposes of Section 305(b)(2).

A “series of distributions” encompasses all distributions (whether or not pursuant to a plan) made or deemed made by a corporation that have the result of the receipt of cash or property by some shareholders and an increase in the proportionate interests of other shareholders. Under applicable U.S. Treasury regulations, the receipt of

54

cash or property within 36 months before or after the distribution of stock or stock rights may be taken into account in determining whether a disproportionate distribution has occurred.

In cases where there is more than one class of stock outstanding, each class of stock is to be considered separately in determining whether a shareholder has increased his proportionate interest in the assets or earnings and profits of a corporation. In determining whether a distribution or a series of distributions has the result of a disproportionate distribution, any security convertible into stock of the distributing corporation is treated as outstanding stock of the distributing corporation.

The applicable U.S. Treasury regulations provide an example of a corporation that has one class of common stock outstanding and interest-paying securities that are convertible into its common stock and have a fixed conversion ratio that is not subject to a full adjustment in the event stock rights are distributed to the common shareholders. In this example, the corporation distributes rights to acquire additional stock to its common shareholders and, during the same year, pays interest on the convertible securities. The applicable U.S. Treasury regulations conclude that the distribution of stock rights is taxable since the distribution increases the proportionate interests of the common shareholders in the assets and earnings and profits of the corporation as compared to the securities and the cash payment of interest to holders of securities is treated as a distribution of property to other shareholders. However, if the conversion ratio of the securities were fully adjusted to reflect the distribution of rights to the common shareholders, the applicable U.S. Treasury regulations conclude that the distribution of stock would not be taxable because the rights to acquire stock would not increase the proportionate interests of the common shareholders in the assets and earnings and profits of the corporation as compared to the securities.

The Company has one class of Common Shares outstanding and two series of interest-paying securities that are convertible into Common Shares (the “Convertible Securities”). In the Offering, the Company is distributing the Rights only to the holders of Common Shares. The Company is also making interest payments to the holders of the Convertible Securities within the 36-month period before and after the distribution of the Rights. However, the indenture for the Convertible Securities provides for an adjustment to the conversion ratio of the Convertible Securities to reflect the distribution of Rights to the holders of the Common Shares and, therefore, the Company intends to take the position that the distribution of the Rights should not result in an increase to any shareholder’s proportionate interest in the Company’s earnings and profits or assets and, accordingly, it is expected that the receipt of Rights with respect to the Company’s Common Shares should be non-taxable to U.S. Holders of Common Shares.

The Company’s position regarding the treatment of the distribution of the Rights as a non-taxable distribution is not binding on the IRS, or the courts. If this position is finally determined by the IRS or a court to be incorrect, whether on the basis that the issuance of the Rights is a disproportionate distribution or otherwise, the fair market value of the Rights would be taxable to a U.S. Holder as dividend income to the extent of the Company’s current or accumulated earnings and profits, computed under U.S. federal tax principles. Distributions in excess of the Company’s current and accumulated earnings and profits would be treated as a non-taxable return of capital to the extent of a U.S. Holder’s tax basis in its Common Shares and thereafter as capital gain from the sale or exchange of such Common Shares.

The discussion below assumes that the issuance of the Rights is not part of a disproportionate distribution within the meaning of the Code and that the issuance of the Rights to U.S. Holders of the Company’s Common Shares is treated as a non-taxable distribution.

Holding Period in the Rights

The holding period for the Rights received in the Offering by a U.S. Holder of Common Shares will include the holding period for the Common Shares with respect to which the Rights were received.

55

Tax Basis in the Rights

A U.S. Holder’s tax basis in the Rights received in the Offering will depend on the relative fair market value of the Rights received by such U.S. Holder and the Common Shares owned by such U.S. Holder at the time the Rights are distributed. If either (i) the fair market value of the Rights on the date such Rights are distributed is equal to at least 15% of the fair market value on such date of the Common Shares with respect to which the Rights are received or (ii) the U.S. Holder elects, in its U.S. federal income tax return for the taxable year in which the Rights are received, to allocate part of its tax basis in such Common Shares to the Rights, then upon exercise or disposition (other than a lapse) of the Rights, the U.S. Holder’s tax basis in the Common Shares will be allocated between the Common Shares and the Rights in proportion to their respective fair market values on the date the Rights are distributed. If the Rights received by a U.S. Holder have a fair market value that is less than 15% of the fair market value of the Common Shares owned by such U.S. Holder at the time the Rights are distributed and such U.S. Holder does not make the election described in the previous sentence, the U.S. Holder’s tax basis in the Rights will be zero. Fair market value is defined generally as the price at which property would hypothetically change hands between a willing buyer and a willing seller, where neither is under any compulsion to buy or sell. Fair market value is a factual determination. While the Rights are expected to trade on the TSX, it is not clear whether the trading volume will be sufficient to reliably establish the fair market value of the Rights. The determination of the proper allocation of tax basis between the Rights and the Common Shares for a U.S. Holder that exercises the over-subscription privilege is unclear.

U.S. Holders should consult their own tax advisors to determine the proper allocation of tax basis between the Rights and the Common Shares with respect to which the Rights are received.

Exercise of the Rights

A U.S. Holder will generally not recognize gain or loss on the exercise of the Rights and related receipt of Common Shares. A U.S. Holder’s initial tax basis in the Common Shares received on the exercise of the Rights should be equal to the sum of (i) such U.S. Holder’s tax basis in such Rights, if any, plus (ii) the exercise price paid by such U.S. Holder on the exercise of such Rights. A U.S. Holder’s holding period for the Common Shares received on the exercise of the Rights will begin on the day that such Rights are exercised by such U.S. Holder.

If a U.S. Holder exercises the Rights after disposing of Common Shares with respect to which the Rights were received, then certain aspects of the exercise of the Rights is unclear, including (i) the allocation of tax basis between the Common Shares previously sold and the Rights, (ii) the impact of such allocation on the amount and timing of gain or loss recognized with respect to the Common Shares previously sold and (iii) the impact of such allocation on the tax basis of the Common Shares acquired upon exercise of the Rights. A U.S. Holder that exercises the Rights received in the Offering after disposing of the Common Shares with respect to which the Rights were received should consult its own tax advisor regarding the tax consequences associated with the exercise of the Rights and the disposition of the Common Shares, including the potential application of the “wash sale” rules under Section 1091 of the Code.

Disposition of the Rights

Subject to the discussion below under “—Passive Foreign Investment Company Rules,” a U.S. Holder will recognize gain or loss on the sale or other taxable disposition of a Right in an amount equal to the difference, if any, between (i) the amount of cash plus the fair market value of any property received and (ii) such U.S. Holder’s tax basis, if any, in the Right sold or otherwise disposed of. Any gain or loss generally will be capital gain or loss, and will be short-term or long-term depending on whether the Right is treated as having been held for more than one year under the holding period rule described above under “—Receipt, Ownership, Exercise, Lapse and Disposition of the Rights—Holding Period in the Rights.” Long-term capital gains of individuals, estates, and trusts currently are eligible for reduced rates of U.S. federal income tax. The deductibility of capital losses may be subject to limitation.

56

Lapse of the Rights

If a U.S. Holder’s Rights expire, a U.S. Holder generally will not recognize any gain or loss for U.S. federal income tax purposes upon the expiration of the Rights. If a U.S. Holder has tax basis in the expired Rights, such tax basis should be re-allocated to the tax basis of the Common Shares with respect to which the Rights were received. If the Rights expire after a U.S. Holder has disposed of the Common Shares with respect to which the Rights are received, such U.S. Holder should consult its tax advisor regarding its ability to recognize a loss (if any) on the expiration of the Rights.

Distributions on Common Shares

Subject to the discussion below under “—Passive Foreign Investment Company Rules,” the gross amount of distributions, if any, made on our Common Shares received upon exercise of a Right (including any amount withheld in respect of Canadian taxes) generally will be taxable to a U.S. Holder as dividend income to the extent of our current or accumulated earnings and profits, computed under U.S. federal tax principles. Distributions in excess of our current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of a U.S. Holder’s tax basis in the Common Shares and thereafter as capital gain from the sale or exchange of such Common Shares. See “—Sale, Exchange or Other Taxable Disposition of Common Shares.”

A U.S. Holder that receives a dividend paid in Canadian dollars must include in its income the U.S. dollar value of the dividend based on the spot rate of exchange in effect on the date the dividend is received by the U.S. Holder, regardless of whether the Canadian dollars are converted into U.S. dollars on such date. If the Canadian dollars distributed to the U.S. Holder are not converted into U.S. dollars on the date of receipt, the U.S. Holder may recognize foreign currency gain or loss attributable to the actual disposition of any such Canadian dollars it receives as described in “—Exchange of Canadian Dollars for U.S. Dollars.” Foreign currency gain or loss generally will be treated, for U.S. foreign tax credit purposes, as U.S. source ordinary income or loss.

Because we are not a U.S. corporation, U.S. Holders that are corporations generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. Dividends paid with respect to our Common Shares will generally be treated as foreign source income for purposes of computing allowable foreign tax credits for U.S. federal income tax purposes. However, as discussed below under “—Foreign Tax Credit,” for purposes of a U.S. Holder’s ability to credit foreign taxes, all or a portion of such dividends may be treated as U.S.-source income.

Dividends paid on our Common Shares to a non-corporate U.S. Holder generally will be treated as “qualified dividend income” that is taxable to such non-corporate U.S. Holder at preferential capital gain tax rates provided that (i) the Common Shares are readily tradable on an established securities market in the United States or we are eligible for the benefits of a comprehensive income tax treaty with the United States that the IRS has determined is satisfactory and that includes an exchange of information provision (such as the Canada-US Tax Treaty); (ii) we are not a PFIC (as defined herein) for the taxable year during which the dividend is paid or the immediately preceding taxable year (see the discussion below under “—Passive Foreign Investment Company Rules”) and (iii) certain holding period and other requirements are satisfied. It is not clear whether dividends paid on our Common Shares would qualify for qualified dividend income treatment.

Non-corporate U.S. Holders should consult their own tax advisors regarding the availability of the preferential rates applicable to qualified dividend income for any dividends paid with respect to our Common Shares.

Foreign Tax Credit

U.S. Holders may be subject to Canadian withholding tax on distributions paid with respect to our Common Shares received upon exercise of a Right. Subject to certain limitations that may vary depending upon the

57

circumstances, such Canadian withholding tax on distributions paid by us on our Common Shares to a U.S. Holder is generally reduced to 15% pursuant to the Canada-US Tax Treaty, provided that such U.S. Holder is fully entitled to the benefits of the Canada-US Tax Treaty. Subject to the discussion below, U.S. Holders generally may treat the amount of any Canadian withholding taxes as foreign taxes eligible for credit against a U.S. Holder’s U.S. federal income tax liability. Alternatively, a U.S. Holder may, subject to applicable limitations, elect to deduct the otherwise creditable Canadian withholding taxes for U.S. federal income tax purposes.

Canadian withholding taxes must be translated into U.S. dollars using the exchange rate in effect on the day the taxes were withheld (in the case of cash basis and electing accrual basis holders) or at the average exchange rate for the year of accrual (in the case of accrual basis holders who have not made such an election). Any such election will apply for the taxable year in which it is made and all subsequent taxable years, unless revoked with the consent of the IRS.

If a foreign corporation is a “United States-owned foreign corporation” (as defined herein), dividends may be re-characterized as U.S.-source income in the same proportion as the percentage of such foreign corporation’s earnings and profits (as determined under U.S. tax principles) from sources within the United States. A foreign corporation is a “United States-owned foreign corporation” if 50% or more (by vote or by value) of the stock of such corporation is held, directly or indirectly, by United States persons (as defined in the Code). We believe that, as of the date hereof, United States persons own 50% or more of the voting power and value of our Common Shares (whether held directly, indirectly or through attribution), and thus, all or a portion of the dividends received with respect to our Common Shares by a U.S. Holder may be treated as U.S.-source income for purposes of calculating such U.S. Holder’s foreign tax credit limitation. To the extent that a U.S. Holder is unable to establish that all or a portion of a dividend from us is foreign source income, the value of any potential foreign tax credit attributable to any Canadian withholding taxes on our dividends may be limited.

The rules governing the foreign tax credit are complex and their application depends on each taxpayer’s particular circumstances. Accordingly, U.S. Holders should consult their own tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Sale, Exchange or Other Taxable Disposition of Common Shares

Subject to the discussion below under “—Passive Foreign Investment Company Rules,” a U.S. Holder generally will recognize taxable gain or loss upon the sale, exchange, redemption or other taxable disposition of our Common Shares received upon exercise of a Right in an amount equal to the difference between the amount realized and the U.S. Holder’s tax basis in the Common Shares. Any gain or loss recognized on a taxable disposition of our Common Shares will be capital gain or loss. Such capital gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period at the time of the sale, exchange, redemption or other taxable disposition of our Common Shares is more than one year. Long-term capital gains of individuals, estates, and trusts currently are eligible for reduced rates of U.S. federal income tax. The deductibility of capital losses may be subject to limitation.

Exchange of Canadian Dollars for U.S. Dollars

A U.S. Holder’s tax basis in any Canadian dollar received as a dividend on our Common Shares received upon exercise of a Right, or on the sale or other taxable disposition of a Right or our Common Shares received upon exercise of a Right, will be the U.S. dollar value of such Canadian dollar at the spot rate of exchange in effect on the date of receipt of the Canadian dollar. A U.S. Holder will generally recognize gain or loss on a sale, exchange or other taxable disposition of the Canadian dollar equal to the difference between (i) the amount of U.S. dollars, or the fair market value in U.S. dollars of other property received in such disposition, and (ii) the U.S. Holder’s tax basis in such Canadian dollar. Any gain or loss recognized by a U.S. Holder on a sale, exchange or other taxable disposition of the Canadian dollar will be ordinary income or loss and generally will be U.S. source income or loss for U.S. foreign tax credit purposes.

58

Reportable Transactions

A U.S. Holder that recognizes exchange loss with respect to the Rights or the Common Shares received upon exercise of a Right would be required to report the loss on IRS Form 8886 (Reportable Transaction Disclosure Statement) if the loss exceeds the thresholds set forth in the applicable U.S. Treasury regulations. For individuals and trusts, this loss threshold is US$50,000 in any single year. For other types of taxpayers and other types of losses, the thresholds are higher. U.S. Holders should consult their own tax advisors regarding the application of these rules to the receipt, ownership, exercise, lapse and disposition of the Rights and the ownership and disposition of the Common Shares received upon exercise of a Right.

Passive Foreign Investment Company Rules

Adverse U.S. federal income tax rules apply to a U.S. Holder that holds shares or options to acquire shares in a foreign corporation classified as a “passive foreign investment company” (“PFIC”) for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder in any taxable year in which, after applying certain look-through rules, either:

For purposes of determining whether we are a PFIC, we will be treated as earning and owning our proportionate share of the income and assets, respectively, of any of our subsidiary corporations in which we own at least 25% of the value of the subsidiary’s stock.

Based on estimates of our gross income, the nature and value of our assets, the manner in which we conduct our business and our expectation for the manner in which such business will be conducted in the future, we do not believe that we were a PFIC for our 2022 taxable year and do not expect to be treated as a PFIC in the current taxable year. However, the IRS or a court could take a contrary position. Because PFIC status depends on the composition of a company’s income and assets and the market value of its assets from time to time, there can be no assurance that we will not be considered a PFIC for our 2022 taxable year, the current taxable year or any future taxable year.

If we were to be treated as a PFIC for any taxable year in which a U.S. Holder holds our Common Shares (and regardless of whether we remain a PFIC for subsequent taxable years), gain recognized by the U.S. Holder on the sale or other disposition of the Common Shares would be allocated ratably over the U.S. Holder’s aggregate holding period for the Common Shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that taxable year, and an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year. In addition, if we were a PFIC for any taxable year during which a U.S. Holder held the Rights, such U.S. Holder could be taxed on a sale or other disposition of a Right in the same manner that the U.S. Holder would be taxed upon a sale or other disposition of the Common Shares. However, the exercise of an option to acquire a PFIC is, under proposed U.S. Treasury regulations, generally not a taxable disposition for purposes of the PFIC rules, and thus an exercise of a Right into our Common Shares should not be taxable under the special PFIC rules described in this paragraph. Further, to the extent that any distribution received by a U.S. Holder on our Common Shares exceeds 125% of the average of the annual distributions on the Common Shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution will be subject to taxation in the same manner as gain, described immediately above.

59

If we were to be treated as a PFIC, certain elections (such as a “QEF election” or “mark-to-market” election) may be available that could result in a more favorable alternative treatment for U.S. Holders of our Common Shares. Under proposed U.S. Treasury Regulations, if a U.S. Holder has an option to acquire stock of a PFIC, such an option is considered to be PFIC stock also subject to the PFIC rules described above. However, a U.S. Holder may not make a QEF election or mark-to-market election with respect to such an option. In addition, under proposed U.S. Treasury Regulations, if a U.S. Holder holds an option to acquire stock of a PFIC, the holding period with respect to shares of stock of the PFIC acquired upon exercise of such option includes the period that the option was held. As a result, this holding period rule impacts the availability of a timely QEF election or mark-to-market election with respect to the Rights and the Common Shares received upon the exercise of such Rights. Furthermore, if we do not provide the information necessary for U.S. Holders to make a QEF election, such an election may not be available. If we were to be treated as a PFIC for any taxable year in which a U.S. Holder holds the Rights or Common Shares received upon exercise of a Right, such U.S. Holder may (in the case of the Rights) and generally will (in the case of Common Shares) be required to file an annual information return with the IRS reflecting such ownership, regardless of whether any election for an alternative treatment is made.

Because of the complexity and uncertainty of the treatment of the Rights under the PFIC rules, U.S. Holders should consult their own tax advisors regarding the adverse tax consequences that may result from the application of the PFIC rules to the Rights and the Common Shares received upon the exercise of such Rights if we were to be a PFIC, and the availability of, and procedure for making, any qualifying election with respect to thereto along with the consequences of making any such available election in their particular circumstances.

Information Reporting and Backup Withholding

Information reporting generally will apply to payments of dividends (including deemed dividends) and the proceeds of the sale or other disposition (including a redemption, exchange or retirement) of the Rights or Common Shares received upon exercise of a Right that are paid by a U.S. paying agent or other U.S. intermediary. Backup withholding will apply to such payments unless a U.S. Holder provides to the applicable withholding agent its taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establishes an exemption from backup withholding. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against the U.S. Holder’s U.S. federal income tax liability, if any, and a refund may be obtained from the IRS if the amounts withheld exceed the U.S. Holder’s actual U.S. federal income tax liability and the U.S. Holder timely provides the required information or appropriate claim form to the IRS. U.S. Holders should consult their own tax advisors regarding any additional tax reporting or filing requirements they may have as a result of the receipt, ownership, exercise, lapse and disposition of the Rights and the ownership and disposition of our Common Shares received upon exercise of a Right.

Foreign Financial Asset Reporting

Certain U.S. Holders are required to report information to the IRS with respect to their ownership of “specified foreign financial assets,” which generally will include the Rights and our Common Shares, subject to certain exceptions (including an exception for Rights and Common Shares held in accounts maintained by certain financial institutions). U.S. Holders who fail to report required information could become subject to substantial penalties. Prospective purchasers should consult their own tax advisors regarding the possible implications of these rules to their ownership of the Rights and our Common Shares.

THE PRECEDING DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE PARTICULAR U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF RECEIVING, OWNING, EXERCISING, ALLOWING THE LAPSE OF AND DISPOSING OF THE RIGHTS AND OWNING AND DISPOSING OF COMMON SHARES RECEIVED UPON EXERCISE OF A RIGHT, INCLUDING THE CONSIDERATIONS OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

We have not employed any brokers, dealers, dealer-managers, or underwriters in connection with the solicitation of exercise of Rights.

We will not pay the Standby Purchasers a fee.

CURRENCY AND EXCHANGE RATES

In this prospectus, unless otherwise specified, all references to “dollars” or “US$” are to U.S. dollars and references to “C$” are to Canadian dollars.

The following table sets forth certain exchange rates as reported by the Bank of Canada. Such rates are set forth as Canadian dollars per United States dollar.

CONSOLIDATED CAPITALIZATION

There have been no material changes in our capital structure since September 30, 2023, the date of our financial statements for the most recently completed financial period.

ENFORCEMENT OF CIVIL LIABILITIES

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that (i) the Company is a corporation incorporated under the ABCA and is governed by the laws of Alberta, (ii) certain of its directors and executive officers are resident outside the United States, (iii) certain experts named in this prospectus are resident outside the United States and (iv) all or a substantial portion of the assets of the foregoing persons may be located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon the Company, and those directors, officers and experts, or to realize in the United States upon judgments of courts of the United States predicated upon civil liability provisions of the United States federal securities laws.

LEGAL MATTERS

Certain legal matters in connection with the securities will be passed upon by Bennett Jones LLP, Calgary, Alberta, Canada, with respect to Canadian legal matters.

PART II.

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth an itemization of the fees and expenses in connection with the issuance and distribution of the securities being registered. All of the amounts shown are estimates, except for the SEC registration fee.

Under Section 124 of the ABCA, except in respect of an action by or on behalf of us to procure a judgment in our favor, we may indemnify a current or former director or officer or a person who acts or acted at our request as a director or officer of a body corporate of which we are or were a shareholder or creditor and the heirs and legal representatives of any such persons (collectively, “Indemnified Persons”) against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by any such Indemnified Person in respect of any civil, criminal or administrative, investigative or other actions or proceedings to which the Indemnified Person is involved by reason of being or having been our director or officer, if (i) the Indemnified Person acted honestly and in good faith with a view to our best interests, and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the Indemnified Person had reasonable grounds for believing that such Indemnified Person’s conduct was lawful (collectively, the “Discretionary Indemnification Conditions”).

Notwithstanding the foregoing, the ABCA provides that an Indemnified Person is entitled to indemnity from us in respect of all costs, charges and expenses reasonably incurred by the Indemnified Person in connection with the defense of any civil, criminal, administrative, investigative or other action or proceeding to which the Indemnified Person is involved by reason of being or having been our director or officer, if the Indemnified Person (i) was not judged by a court or competent authority to have committed any fault or omitted to do anything that the person ought to have done and, (ii) fulfills the Discretionary Indemnification Conditions (collectively, the “Mandatory Indemnification Conditions”). We may advance funds to an Indemnified Person for the costs, charges and expenses of such a proceeding; however, the Indemnified Person shall repay the funds if the Indemnified Person does not fulfill the Mandatory Indemnification Conditions. The indemnification may be made in connection with a derivative action only with court approval and only if the Discretionary Indemnification Conditions are met.

As contemplated by Section 124(4) of the ABCA and our by-laws, we have acquired and maintain liability insurance for our directors and officers with coverage and terms that are customary for a company of our size in our industry of operations.

Our by-laws provide that we shall, to the maximum extent permitted under the ABCA or otherwise by applicable law, indemnify our present and former directors and officers as well as any person who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, and their heirs and legal representatives, against all costs, charges and expenses, including any amount paid to settle an action or

II-1

satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other action or proceeding to which he or she is made a party to or involved by reason of that association with us or such other entity.

Our by-laws also provide that none of our directors or officers shall be liable for the acts, receipts, neglects or defaults of any other director, officer or employee, or for joining in any receipt or act for conformity, or for any loss, damage or expense happening to us through the insufficiency or deficiency of title to any property acquired by us or for or on behalf of us or for the insufficiency or deficiency of any security in or upon which any of our moneys shall be placed or invested, or for any loss or damage arising from the bankruptcy, insolvency or tortious act of any person, firm or corporation, including any person, firm or corporation with whom or with which any moneys, securities or effects shall be lodged or deposited, or for any loss, conversion, misapplication or misappropriation of or any damage resulting from any dealings with our moneys, securities or other assets, or for any other loss, damage or misfortune whatsoever which may happen in the execution of the duties of his or her office or trust or in relation thereto; provided that nothing in our by-laws shall relieve any director or officer from the duty to act in accordance with the ABCA and the regulations thereunder. The foregoing is premised on the requirement under our by-laws that each of our directors and officers, in exercising his or her powers and discharging his or her duties, shall act honestly, in good faith and with a view to our best interests and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

We have also entered into indemnification agreements with all of our directors and executive officers. Subject to certain exceptions, these agreements generally require that we indemnify and hold our directors and officers and their respective heirs, executors, administrators and other legal representatives (collectively, the “DIRTT Indemnified Parties”) harmless, to the fullest extent permitted by law, for any losses that they may incur in relation to their association with us and our subsidiaries as directors and officers. Such indemnity will only be available if the DIRTT Indemnified Party: (i) acted honestly and in good faith with a view to our best interest or, as the case may be, to the best interest of an entity for which the DIRTT Indemnified Party acted as a director, officer or in a similar capacity at our request and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had acted with a reasonable belief that his or her conduct was lawful. The indemnification agreements also provide that, upon the request of a DIRTT Indemnified Party, we shall advance expenses to the DIRTT Indemnified Parties so that they may properly investigate, defend or appeal any applicable claim.

On June 2, 2023, the Company issued 3,899,745 Common Shares to 22NW and Aron English (the “22NW Group”) pursuant to a Debt Settlement Agreement and a Share Issuance Agreement, each between the Company and the 22NW Group, at a deemed price of US$0.40 per Common Share.

The issuance of Common Shares pursuant to the Share Issuance Agreement was subject to approval by the Company’s shareholders, and the Company’s shareholders subsequently approved such issuance at the Company’s 2023 annual meeting of shareholders held on May 30, 2023.

Dear Sirs/Mesdames:

Introduction

The Rights and the Rights Shares will be issued in the United States pursuant to a prospectus (as amended through the date hereof including all exhibits thereto) (the “Prospectus”) included in the Registration Statement on Form S-1 (Registration No. 333-275172) (the “Registration Statement”), initially filed with the U.S. Securities and Exchange Commission (the “Commission”) on October 26, 2023.

DIRTT Environmental Solutions Ltd.

7303 – 30th Street SE

Dear Sirs/Mesdames:

We have acted as Canadian counsel to DIRTT Environmental Solutions Ltd., an Alberta corporation (the “Company”), in connection with the distribution of transferable subscription rights (the “Rights”) to purchase up to an aggregate of [●] common shares in the capital of the Company (the “Rights Shares”) to holders of common shares of the Company (the “Rights Offering”). The Rights and the Rights Shares will be issued in the United States pursuant to a prospectus (as amended through the date hereof including all exhibits thereto) included in the Registration Statement on Form S-1 (Registration No. 333-275172) (the “Registration Statement”), initially filed with the U.S. Securities and Exchange Commission (the “Commission”) on October 26, 2023.

The opinion expressed below is limited to the federal laws of Canada on the date hereof. We express no opinion herein with respect to the laws of any other jurisdiction or as to matters governed by the laws of any other jurisdiction. The statutory provisions, regulations, and interpretations upon which our opinions are based are subject to change, and such changes could apply retroactively. We assume no responsibility to advise you of any subsequent changes in existing law or facts, nor do we assume any responsibility to update this opinion with respect to any matters expressly set forth herein, and no opinions are to be implied or may be inferred beyond the matters expressly so stated.

Based upon and subject to the foregoing, we are of the opinion that the discussion contained in the Registration Statement under the caption “Certain Canadian Federal Income Tax Considerations”, insofar as it presents legal conclusions with respect to matters of Canadian federal income tax law, accurately sets forth the principal Canadian federal income tax considerations generally applicable to the receipt or exercise of the Rights and owning and disposing of the Rights Shares received upon exercise of the Rights by a holder described therein, subject to the assumptions, limitations and qualifications referred to therein.

Consent is hereby given to the use of our name in the Registration Statement, and to the filing, as an Exhibit to the Registration Statement, of this opinion. In giving such consent, we do not hereby admit that we are (a) in the category of persons whose consent is required under Section 7 of the Securities Act or (b) experts with respect to any part of the Registration Statement, including this Exhibit, within the meaning of the term “expert” under the Securities Act.

Yours truly,

In addition, the Company has filed a registration statement on Form S-1 (File No. 333-275172) containing a prospectus (the “U.S. Prospectus”) with respect to the Offering to which this Notice relates with the United States Securities and Exchange Commission (the “SEC”) under the United States Securities Act of 1933.

Alternatively, the Company will arrange to send you the U.S. Prospectus if you request it by contacting the Company’s investor relations group by email at ir@dirtt.com or 1-800-605-6707.

Reference in this Notice to “we”, “our”, “us” and similar terms means DIRTT. Reference in this Notice to “you”, “your” and similar terms mean shareholders of the Company.

1.    Who can participate in the rights offering?

Rights will be distributed, at no charge, to holders of Common Shares of record as of the close of business on                , 2023 (the “Record Date”) in an Eligible Jurisdiction (as defined below) or who is an Approved Holder (as defined below). Rights holders may participate in the Offering by exercising Rights and subscribing for Common Shares thereunder. If you are resident in or otherwise subject to securities laws of the United States (“U.S.”), you should read the U.S. Prospectus, available on the SEC’s website at www.sec.gov.

2.    Who is eligible to receive and exercise rights?

The Rights are being offered to holders of our Common Shares as of the close of business on the Record Date residing in each of the provinces and territories of Canada and in the U.S. (the “Eligible Jurisdictions”). Shareholders not resident in Eligible Jurisdictions (“Ineligible Holders”) that are able to establish to the Company’s satisfaction, in its sole discretion, not later than                , 2023, that an offering to and subscription by such holder of Rights and Common Shares, respectively, is lawful and in compliance with all securities and other laws applicable in the Eligible Jurisdictions and in the jurisdiction where such Ineligible Holder is resident and would not require that the Company file any document, take any proceeding, make any application, obtain any approval, give any notice or make any payment, in each case of any kind or nature whatsoever, including by delivering a representation letter in the form presented by the Company (an “Approved Holder”), will be eligible to receive Rights.

Page 1 of 4

This Notice does not constitute an offer or a solicitation in any jurisdiction in which, or to any person to whom, such offer or solicitation is unlawful. No Rights or Common Shares issuable upon exercise thereof are offered for sale, and no offers to purchase securities are solicited, in any jurisdiction that is not an Eligible Jurisdiction, or to or from Ineligible Holders.

Ineligible Holders will not receive a rights direct registration system advice (“Rights DRS Advice”) or a subscription form (the “Subscription Form”) (as described in Item 6 below), but will be sent a letter advising (i) that their Rights will be held by Computershare Investor Services Inc. (the “Subscription Agent”), as agent for the benefit of all such Ineligible Holders, and (ii) how Ineligible Holders might establish their ability to participate in the Offering and subscribe for Common Shares as an Approved Holder, failing which the Subscription Agent will attempt to sell the Rights for the benefit of such Ineligible Holder.

3.    How many rights are we offering?

We expect to distribute                Rights entitling the holders thereof to subscribe for and purchase an aggregate of                Common Shares at a price of C$                per whole Common Share.

4.    How many rights will you receive?

Registered holders of our Common Shares as of the close of business on the Record Date will receive one Right for every Common Share so held.

5.    What does one right entitle you to receive?

Each Right will entitle its holder to purchase                Common Shares at a subscription price of C$                per whole Common Share (the “Subscription Price”), exercisable for whole Common Shares only, on or before the Expiration Time on the Expiration Date (the “Basic Subscription Privilege”). You may not exercise your Rights to acquire less than one whole Common Share. As a result,                Rights are required to subscribe for one whole Common Share. No fractional Common Shares will be issued. Where any exercise of Rights would otherwise entitle a holder of Rights to receive fractional Common Shares, the holder’s entitlement will be reduced and rounded down to the next lowest whole number of Common Shares, and the fraction shall be cancelled without any repayment of capital or other consideration therefor.

If you fully exercise your Basic Subscription Privilege (other than those Rights to acquire less than one whole Common Share, which cannot be exercised) and our other shareholders do not fully exercise their Basic Subscription Privileges, you may also exercise an additional subscription privilege to purchase additional Common Shares (the “Additional Subscription Privilege”) not issued under the Basic Subscription Privilege, subject to the availability and pro rata allocation of Common Shares among shareholders exercising this Additional Subscription Privilege. To the extent the number of Common Shares not issued under the Basic Subscription Privilege is not sufficient to satisfy all of the properly exercised Additional Subscription Privilege requests, then the available Common Shares will be prorated among those who properly exercised Additional Subscription Privileges based on the number of Common Shares that such Rights holder subscribed for under the Basic Subscription Privilege compared to the total number of Common Shares subscribed for under the Basic Subscription Privilege by the holders properly exercising the Additional Subscription Privilege. If this pro rata allocation results in any shareholder receiving a greater number of Common Shares than the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, then such shareholder will be allocated only that number of Common Shares for which the shareholder subscribed for pursuant to the exercise of the Additional Subscription Privilege, and the remaining Common Shares will be allocated among all other shareholders exercising the Additional Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Common Shares have been allocated or all Additional Subscription Privilege exercises have been fulfilled, whichever occurs earlier.

Rights will be evidenced by a Rights DRS Advice issued under the direct registration system administered by the Subscription Agent.

To exercise your Rights, you must complete the Subscription Form included with the Rights DRS Advice and deliver it to the Subscription Agent, together with full payment for all the Rights you elect to exercise under the Basic Subscription Privilege and Additional Subscription Privilege, before the expiration of the Offering. You may deliver the required documents and payments by mail or commercial carrier. If regular mail is used for this purpose, we recommend using registered mail, properly insured, with return receipt requested.

Page 2 of 4

If you are a beneficial owner of Common Shares that are registered in the name of a broker, dealer, bank or other nominee, you should instruct the Registered Holder of your Common Shares to exercise your Rights on your behalf and deliver all required documents and payment before the Expiration Time on the Expiration Date. You should contact the Registered Holder of the rights as soon as possible as they may establish an earlier deadline for receiving subscription instructions. See Item 7 below.

6.    How will you receive your rights?

Rights will be evidenced by a Rights DRS Advice issued under the direct registration system administered by the Subscription Agent.

Registered Eligible Holders – If you hold your Common Shares in your own name, you are a Registered Holder. A Rights DRS Advice representing the total number of Rights to which you are entitled as at the Record Date, together with a subscription form (a “Subscription Form”), is enclosed with this Notice.

Beneficial Eligible Holders – If you hold your Common Shares in the name of a broker, bank, or other nominee, then your broker, bank, or other nominee is the Registered Holder of the Common Shares you own. The Registered Holder must exercise the Rights on your behalf for the Common Shares you wish to purchase.
