DIRTT agrees to indemnify and hold harmless each Standby Purchaser and its affiliates and each of their respective directors, officers, employees, members, shareholders, partners, agents and advisors (each such person, an “Indemnified Party”) to the fullest extent permitted by law from and against any losses, claims, damages and liabilities, joint or several (collectively, the “Damages”), to which such Indemnified Party may become subject in connection with or otherwise relating to or arising from (i) any claims by a third party against an Indemnified Party in respect of the obligations of the Standby Purchaser under this Agreement; (ii) any inaccuracy in or breach or nonfulfillment of or noncompliance with any of the covenants or agreements or representations and warranties made by DIRTT in this Agreement; or (iii) the Rights Offering Documents, including, without limitation, by reason of or in any way arising, directly or indirectly, out of any misrepresentation or alleged misrepresentation therein, the Rights Offering, or the use of proceeds thereunder, other than, in each case, Damages resulting from the Indemnified Party’s wilful misconduct, gross negligence, or breach of this Agreement (collectively, the “Indemnifiable Events”); provided, that DIRTT will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in any Rights Offering Document in reliance upon and in conformity with written information furnished to DIRTT by or on behalf of any Standby Purchaser specifically for inclusion in the Rights Offering Documents.

DIRTT will reimburse each Indemnified Party for all reasonable fees and expenses (including the reasonable fees and expenses of counsel) (collectively, “Expenses”) as incurred in connection with investigating, preparing, pursuing or defending any threatened or pending claim, action, proceeding or investigation (collectively, the “Proceedings”) arising from an Indemnifiable Event, whether or not such Indemnified Party is a formal party to such Proceeding; provided, that DIRTT will not be liable to any such Indemnified Party to the extent that any Damages are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted solely from the gross negligence or wilful misconduct of the Indemnified Party seeking indemnification hereunder. DIRTT will advance funds to an Indemnified Party for the reasonable costs, charges and expenses related to any Proceedings. The Indemnified Party shall repay these funds if the Indemnified Party does not fulfill the conditions of Section 7.1.

If for any reason other than in accordance with this Agreement, the foregoing indemnity is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless in respect of an Indemnifiable Event, then DIRTT will contribute to the amount paid or payable by an Indemnified Party as a result of Damages (including all Expenses incurred) in respect of an Indemnifiable Event in such proportion as is appropriate to reflect the relative benefits to DIRTT and/or the Shareholders on the one hand, and the applicable Standby Purchaser and/or any other Indemnified Party on the other hand, in connection with the matters covered by this Agreement or, if the foregoing allocation is not permitted by applicable law, not only such relative benefits but also the relative faults of such parties as well as any relevant equitable considerations. In ascertaining relative fault, reference shall be made to, among other things, whether any alleged untrue statement or omission or any alleged conduct relates to information provided by DIRTT or other conduct by DIRTT (or its employees or other agents) on the one hand, or by the applicable Standby Purchaser, on the other hand.

DIRTT agrees not to enter into any waiver, release or settlement of any Proceeding (whether or not the Standby Purchaser or any other Indemnified Party is a formal party to such Proceeding) in respect of which indemnification may be sought hereunder without the prior written consent of the Standby Purchasers (which consent will not be unreasonably withheld), unless such waiver, release or settlement (i) includes an unconditional release of the Standby Purchaser and each Indemnified Party from all liability arising out of such Proceeding and (ii) does not contain any factual or legal admission by or with respect to any Indemnified Party or any adverse statement with respect to the character, professionalism, expertise or reputation of any Indemnified Party or any action or inaction of any Indemnified Party.

The indemnity, reimbursement and contribution obligations of DIRTT hereunder will be in addition to any liability which DIRTT may have at common law or otherwise to any Indemnified Party and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of DIRTT or an Indemnified Party. The provisions of this Article 7 will survive the modification or termination of this Agreement.

DIRTT may terminate this Agreement by notice in writing to the Standby Purchasers if the Closing has not occurred, or the Rights Offering is otherwise terminated or cancelled, on or before the Outside Date; provided that DIRTT has used commercially reasonable efforts to comply with its obligations under this Agreement.

Any Standby Purchaser may terminate this Agreement as to itself only by notice in writing to DIRTT if:

any of the conditions precedent to the Closing, as set forth in Section 3.7 of this Agreement have not been satisfied or waived by such Standby Purchaser by the Expiry Time (subject to any cure period) or the Rights Offering is otherwise terminated or cancelled;

any order to cease trading the securities of DIRTT on the TSX is made by a competent regulatory authority and that order is still in effect; or

the Closing has not occurred on or before the Outside Date; provided that each Standby Purchaser has used commercially reasonable efforts to comply with its obligations under this Agreement, except that the right to terminate this Agreement under this Subsection 8.2(c) shall not be available to any Standby Purchaser whose failure to fulfill any of its obligations has been the cause of, or resulted in, the failure of Closing to occur by the Outside Date.

Any notice or other communication required or permitted to be given hereunder shall be in writing and shall be delivered by personal delivery, prepaid courier, or email, addressed as follows:

if to DIRTT:

if to 22NW:

if to 726:

Subject to applicable law and the rules and regulations applicable to DIRTT and the Standby Purchasers, the Standby Purchasers shall not issue any press release or public announcement relating to matters provided for herein without the approval of DIRTT, which approval may not be unreasonably withheld or delayed; provided, that, in no case shall the foregoing prevent any of the Standby Purchasers from satisfying any obligation under Applicable Securities Law, which shall include, for greater certainty but without limiting the application of the foregoing, under National Instrument 62-104 – Take-Over Bids and Issuer Bids.

Time shall be of the essence hereof.

At or promptly following the Closing, DIRTT shall reimburse each Standby Purchaser for all its reasonable and customary out-of-pocket costs and expenses and reasonable attorneys’ fees incurred by such Standby Purchaser in connection with this Agreement, provided such costs, expenses and fees shall not exceed $30,000 for each Standby Purchaser, following DIRTT’s receipt of all reasonably requested documentation to support the incurrence by such Standby Purchaser of such costs, expenses and fees.

This Agreement shall enure to the benefit of and be binding upon the parties hereto and their respective successors and Permitted Assignees, provided, that, in no case shall this Agreement create any agreement between 22NW and 726 in respect of acquiring, holding, voting, or disposing of Common Shares or Rights, and neither of them shall have any right hereunder to enforce the obligations of the other arising hereunder. The parties acknowledge that this Agreement is between DIRTT and each of the Standby Purchasers and nothing herein is intended to bind or obligate any third parties, including the directors, officers or personnel of the Standby Purchasers in any individual capacity.
