Exhibit 4.2

DESCRIPTION OF COMMON SHARES

General

DIRTT Environmental Solutions Ltd. (“DIRTT,” the “Company,” “we” or “our”) is incorporated in Alberta, Canada, under the Business Corporations Act (Alberta) (as amended, the “ABCA”). The rights of DIRTT’s common shares are generally governed by the ABCA and DIRTT’s articles of amalgamation (our “articles of amalgamation”) and amended and restated by-laws (our “by-laws”).

The following is a description of DIRTT’s common shares, without par value, which are the only securities of DIRTT registered pursuant to Section 12 of the Securities Exchange Act of 1934. This brief description is based upon our articles of amalgamation, our by-laws, and provisions of applicable law. The following description does not purport to be complete and is subject to, and qualified in its entirety by, the full text of our articles of amalgamation and our by-laws, which are incorporated by reference or filed as exhibits to our most recent Annual Report on Form 10-K and are incorporated by reference herein, and amendments or restatements of each will be filed with the Securities and Exchange Commission (the “SEC”) in future periodic or current reports in accordance with SEC rules.

For more detailed information about the rights of DIRTT’s common shares, you should refer to our articles of amalgamation, our by-laws, and provisions of applicable law.

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) 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.

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 of directors of the Company (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 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. The by-laws provide that a quorum is present if there are at least two persons present in person representing, in the aggregate, not less than 25% of the outstanding shares carrying voting rights at the meeting. In connection with our listing on the Nasdaq Global Select Market (“Nasdaq”), we have undertaken to present, and will present, at our next annual and special meeting of shareholders to be held on May 22, 2020, an amendment to our by-laws that would set the quorum threshold at 33-1/3% of our outstanding common shares (represented either in person or by proxy) for future meetings of shareholders. We have also undertaken to postpone or adjourn the meeting unless at least 33-1/3% of our outstanding common shares are represented, either in person or by proxy, at the meeting. Should our shareholders not approve the by-law quorum amendment at this meeting, we will postpone or adjourn any future meetings of shareholders unless at least 33-1/3% of our outstanding common shares are represented at such meetings and will continue to present the by-law quorum amendment at future meetings of shareholders until passed.

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 distributing corporation 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. Additionally, at least one-fourth of the directors must be resident Canadians.

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 subsidiaries’ officers and directors, as permitted by our by-laws and the ABCA.

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:

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 15^th 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 and the Rights Plan (as defined herein) 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.

Shareholder Rights Plan

On April 3, 2014, our Board adopted a shareholder rights plan agreement, as amended from time to time (the “Rights Plan”), which was ratified by our shareholders on May 13, 2014 and May 3, 2017. The Rights Plan is designed to ensure that our shareholders are treated equally and fairly in connection with any initiative to acquire control of the Company. The Rights Plan is intended to: (i) prevent, to the extent possible, a creeping takeover of the Company; (ii) provide us with additional time to pursue alternatives to maximize shareholder value in the event an unsolicited takeover bid is made for all or a portion of our outstanding common shares; and (iii) discourage certain discriminatory and coercive aspects of takeovers. The Rights Plan is set to expire at the close of our annual meeting of shareholders in 2020, unless ratified by our shareholders at or prior to such meeting.

The Rights Plan provides that one right will be issued by us in respect of each common share. The rights initially attach to and trade with the common shares and no separate certificates will be issued unless an event triggering the rights occurs. The rights will become exercisable and begin trading separately from the common shares if a person acquires “beneficial ownership” (as defined in the Rights Plan) of 20% of more of our common shares without complying with the “Permitted Bid” provisions of the Rights Plan. Should such an acquisition occur or be announced, each right would then entitle the shareholder to acquire an additional common share at an initial exercise price equal to three times the market price at the applicable time.

Under the Rights Plan, a Permitted Bid is a takeover bid made to all holders of the common shares and which is open for acceptance for not less than 60 days. If at the end of 60 days at least 50% of the outstanding common shares, other than those owned by the offeror and certain related parties have been tendered, the offeror may take up and pay for the common shares but must extend the bid for a further 10 days to allow other shareholders to tender.

The issuance of common shares upon the exercise of the rights is subject to receipt of certain regulatory approvals.

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). 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, which order may be granted where the Competition Tribunal finds that the acquisition substantially prevents or lessens, or is likely to substantially prevent or lessen, competition.

This legislation also requires any person or persons who intend to acquire more than 20% of our voting shares or, if such person or persons already own more than 20% of our voting shares prior to the acquisition, more than 50% of voting our shares, to file a notification with the Canadian Competition Bureau if certain financial thresholds are exceeded. Where a notification is required, unless an exemption is available, the legislation prohibits completion of the acquisition until the expiration of the applicable statutory waiting period, unless the Commissioner either waives or terminates such waiting period.

Investment Canada Act. The Investment Canada Act requires each “non-Canadian” (as defined in the Investment Canada Act) that acquires “control” of a “Canadian business,” where the acquisition of control is not a reviewable transaction, to file a notification in prescribed form with the Canadian Government (Department of Innovation, Science and Economic Development) not later than 30 days after closing. Subject to certain exemptions, a transaction that is reviewable under the Investment Canada Act may not be implemented until an application for review has been filed and the responsible Minister of the federal cabinet has determined that the investment is likely to be of “net benefit to Canada” taking into account certain factors set out in the Investment Canada Act.

Under the Investment Canada Act, 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 Investment Canada Act and the enterprise value of our business (as determined pursuant to the Investment Canada Act) were to be equal to or greater than C$1.568 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 Investment Canada Act) were to be equal to or greater than C$1.045 billion. Different rules apply if the non-Canadian investor is a “state owned enterprise” (as determined pursuant to the Investment Canada Act). The Investment Canada Act 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 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 one-third or more, 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 Investment Canada Act, the Canadian Government may review on a discretionary basis a much broader range of investments by a non-Canadian to “acquire, in whole or part, or to establish an entity carrying on all or any part of its operations in Canada” to assess whether such investment may be injurious to national security. No financial threshold applies to a national security review. The federal government has broad discretion to determine whether an investor is a non-Canadian and therefore subject to national security review.

There are limited exemptions to a review of an acquisition of our common shares under the Investment Canada Act, 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 Investment Canada Act.

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

Canadian Federal Income Tax Matters Applicable to Ownership of Our Common Shares

Holders Resident in the United States

The following is a summary of the principal Canadian federal income tax considerations generally applicable under the Income Tax Act (Canada) (together with the regulations thereto, the “Tax Act”) to a beneficial holder of our common shares who, for the purposes of the Tax Act and the Canada-United States Income Tax Convention (1980) (the “Treaty”), and at all relevant times, (i) is not and is not deemed to be a resident in Canada, (ii) is a resident of the United States for the purposes of the Treaty and is entitled to the full benefits thereunder, and (iii) does not use or hold and is not deemed to use or hold our common shares in connection with a business carried on in Canada (each such holder, a “U.S. Resident Holder”). This summary is not generally applicable to a U.S. Resident Holder that is: (i) an insurer carrying on an insurance business in Canada and elsewhere, (ii) a “financial institution,” or (iii) an “authorized foreign bank,” each as defined in the Tax Act. Such U.S. Resident Holders should consult their own tax advisors.

This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations applicable to a U.S. Resident Holder. The income and other tax consequences of acquiring, holding or disposing of our common shares will vary depending on a holder’s particular status and circumstances, including the country, province or territory in which the holder resides or carries on business. This summary is not intended to be, nor should it be construed to be, legal or tax advice to any particular holder. No representations are made with respect to the income or other tax consequences to any particular holder. Holders should consult their own tax advisors for advice with respect to the income and other tax consequences of acquiring, holding and disposing of our common shares in their particular circumstances, including the application and effect of the income and other tax laws of any applicable country, province, state or local tax authority.

This summary does not discuss any non-Canadian income or other tax consequences of acquiring, holding or disposing of common shares. Holders resident or subject to taxation in a jurisdiction other than Canada should be aware that there may be tax consequences both in Canada and in such other jurisdiction. Such consequences are not described herein. Holders should consult with their own tax advisors with respect to their particular circumstances and the tax considerations applicable to them.

Taxation of Dividends

Dividends paid or credited, or deemed to be paid or credited, on our common shares to a U.S. Resident Holder will be subject to Canadian withholding tax at the rate of 25% of the gross amount of the dividend, subject to reduction under the provisions of the Treaty. Under the Treaty, the rate of Canadian withholding tax applicable to a U.S. Resident Holder that is the beneficial owner of dividends is generally reduced to 15% of the gross amount of the dividend, and, if such U.S. Resident Holder is a company that owns at least 10% of our voting shares at the time of the dividend, the rate of Canadian withholding tax is reduced to 5% of the gross amount of the dividend. The Company will be required to deduct and withhold the required amount of Canadian withholding tax from any dividends and to remit such amount to the Canada Revenue Agency for the account of the U.S. Resident Holder. U.S. Resident Holders who may be eligible for a reduced rate of withholding tax on dividends pursuant to the Treaty should consult with their own tax advisors with respect to taking all appropriate steps in this regard.

Disposition 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 shares 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 Treaty.

Generally, a common share of a particular U.S. Resident Holder will not be “taxable Canadian property” of such U.S. Resident Holder at any time at which such common share is listed on a “designated stock exchange,” within the meaning of the Tax Act (which includes the Toronto Stock Exchange (“TSX”) and Nasdaq), unless, at any time during the 60-month period immediately preceding that time:

Common shares may also be deemed to be “taxable Canadian property” in certain circumstances as set out in the Tax Act.

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 Canadian tax compliance obligations.
