Subject to the terms and conditions hereof, each of the Shareholders covenants and agrees to sell, assign and transfer to the Purchaser and the Purchaser covenants and agrees to purchase from the Shareholders, the number of Purchased Shares which are beneficially owned by such Shareholder at the Time of Closing. As of the date of this Agreement, the number of Purchased Shares which are beneficially owned by each Shareholder is the number set forth opposite the name of such Shareholder as set out in Schedule "A" attached hereto.

It is acknowledged and agreed that, prior to Closing, the Shareholders may transfer some or all of their NASH Shares to a trustee or nominee shareholder (the "New NASH Shareholder") (while retaining beneficial ownership) as part of personal tax planning and the Purchaser shall be notified in writing of any such transfer not less than five (5) Business Days prior to Closing, on condition that such transferring Shareholder obtains the consent and agreement of the New NASH Shareholder to the Transaction evidenced by the execution and delivery by such New NASH Shareholder of a NASH Shareholder Consent Agreement in the form attached as Schedule "C" hereto. The parties agree that the New NASH Shareholder shall become a party to and be bound by this Agreement holding the NASH Shares previously registered in the name of the transferor of those Purchased Shares.

In addition, for greater certainty, if any Shareholder, may acquire any additional NASH Shares (for example, from another Shareholder that might not be a party to this Agreement, or with the consent of the Purchaser), such additional NASH Shares so acquired shall form part of the Purchased Shares and the applicable Shareholder covenants and agrees to sell, assign and transfer to the Purchaser and the Purchaser covenants and agrees to purchase from such Shareholder the additional NASH Shares held by such Shareholder so acquired, in addition to the Purchased Shares described in Schedule "A".

In consideration for the acquisition of the NASH Shares, the Purchaser shall issue from treasury to the Shareholders pro rata in proportion to their holdings of Purchased Shares at the Time of Closing, an aggregate of 15,800,000 Common Shares, free and clear of any encumbrances (the "Payment Shares"). To the extent a NASH Shareholder is to receive a fractional Payment Share, that entitlement shall be rounded down to the nearest whole number and no consideration shall be payable therefore. The Payment Shares are being issued on a post-Consolidation basis at a deemed value of $0.24 per Payment Share.

At the Time of Closing, NASH may have up to 14,800,000 warrants outstanding (the "Warrants"). At the Time of Closing, each of the Warrantholders shall dispose of their respective right to acquire NASH Shares under the outstanding Warrant held by such Warrantholder at that time and those outstanding Warrants shall be deemed immediately cancelled. In consideration for the disposition by a Warrantholder of each right to acquire one NASH Share under a Warrant, the Warrantholder shall receive the right to acquire one post-Consolidation Common Share (each a "Replacement Warrant" and collectively, the "Replacement Warrants"), rounded down to the nearest whole number of Common Shares. The exercise price under each Replacement Warrant will be equal to the exercise price at the Closing Time under the particular Warrant that was cancelled in consideration for such Replacement Warrant and the expiration date for each Replacement Warrant will be the same date as the expiration date of such Warrant.

The Purchaser agrees that, at the request and expense of any Shareholder who is resident in Canada for the purposes of the Tax Act, the Purchaser shall jointly elect with the Shareholder for the provisions of subsection 85(1) or (2) of the Tax Act and any equivalent provision under provincial legislation (each a "Tax Election Provision") to apply to the Purchased Shares acquired by the Purchaser from the Shareholder. In order to make any such election, the Shareholder shall prepare any prescribed election form (each a "Tax Election Form") and deliver any such Tax Election Form to the Purchaser within 90 days of the Closing Date. Upon receipt, the Purchaser shall sign the Tax Election Form and deliver a copy of the Tax Election Form to the Shareholder by mail using the address that the Shareholder provided to the Purchaser in the Tax Election Form within 30 days. It shall be the sole responsibility of the Shareholder making the request to file the Tax Election Form with the Canada Revenue Agency or relevant provincial Governmental Authority. The Purchaser shall not be liable for any damages arising to a Shareholder for a late filing of a Tax Election Form or any errors or omissions on a Tax Election Form.

Notwithstanding anything contained in this Agreement, the Purchaser does not assume and shall not be liable for any taxes under the Tax Act or under provincial legislation or any other amount whatsoever which may be or become payable by Shareholders including, without limiting the generality of the foregoing, any Tax resulting from or arising as a consequence of the sale by Shareholders to the Purchaser of the Purchased Shares herein contemplated, or the availability (or lack thereof) of any Tax Election Provision, or the content or impact of any election made under any Tax Election Provision.

(iv) there is no government or other insurance covering the Payment Shares or Replacement Warrants; and

(v) an investment in the Payment Shares or Replacement Warrants is speculative and of high risk;

(d) although no hold periods are currently expected to be applicable, the certificates representing the Payment Shares and Replacement Warrants will bear such legends as required by Securities Laws and the policies of the CSE and it is the responsibility of the Securityholder to find out what those restrictions are and to comply with them before selling the Payment Shares or Common Shares issuable upon exercise of a Replacement Warrant; and

(e) the Securityholder is knowledgeable of, or has been independently advised as to, the Applicable Laws of that jurisdiction which apply to the sale of the Purchased Shares and Common Shares issuable on exercise of a Replacement Warrants and the issuance of the Payment Shares and Common Shares issuable on exercise of a Replacement Warrants and which may impose restrictions on the resale of such Payment Shares or Common Shares issuable on exercise of a Replacement Warrant in that jurisdiction and it is the responsibility of the Securityholder to find out what those resale restrictions are, and to comply with them before selling the Payment Shares or Common Shares.

The exercise of any rights of inspection by or on behalf of Purchaser under this Section 7.03(b) will not mitigate or otherwise affect the representations and warranties of NASH hereunder;

(c) except for non-substantive communications, and provided that such disclosure is not otherwise prohibited by reason of a confidentiality obligation owed to a third party for which a waiver cannot be obtained (provided that in such circumstance NASH will be required to disclose that information has been withheld on this basis), furnish promptly to the Purchaser a copy of each notice, report, schedule or other document or communication delivered, filed or received by NASH in connection with or related to the Transaction, any filings under applicable laws and any dealings with any Governmental Authority in connection with or in any way affecting the Transaction as contemplated herein (other than in respect of an Alternative Transaction, in which case a summary of the material terms may be provided);

(c) by the Purchaser, if there has been a material breach by NASH or the Securityholders of any representation, warranty, covenant or agreement set forth in this Agreement or any of the documents contemplated hereby which breach would result in the failure to satisfy one or more of the conditions set forth in Section 4.01 which NASH or the Shareholders, as applicable, fails to cure within ten (10) Business Days after written notice thereof is given by the Purchaser;

(d) by NASH if there has been a material breach by the Purchaser of any representation, warranty, covenant or agreement set forth in this Agreement or any of the documents contemplated hereby which breach would result in the failure to satisfy one or more of the conditions set forth in Section 4.03 which the Purchaser fails to cure within ten (10) Business Days after written notice thereof is given by NASH;

Upon termination of this Agreement in accordance with the terms hereof, the parties hereto shall have no further obligations under this Agreement, other than the obligations contained in Sections 11.03 and 11.08.

Subject to Section 6.04, the Purchaser shall indemnify and save the Securityholders and NASH harmless for and from:

(a) any loss, damages or deficiencies suffered by the Shareholders or NASH as a result of any breach of representation, warranty or covenant on the part of the Purchaser contained in this Agreement or in any certificate or document delivered pursuant to or contemplated by this Agreement; and

(b) all claims, demands, costs and expenses, including legal fees, in respect of the foregoing.

Subject to Section 6.04, NASH shall indemnify and save the Purchaser harmless for and from:

(a) any loss, damages or deficiencies suffered by the Purchaser as a result of any breach of representation, warranty or covenant on the part of NASH contained in this Agreement or in any certificate or document delivered pursuant to or contemplated by this Agreement; and

(b) all claims, demands, costs and expenses, including legal fees, in respect of the foregoing.

Subject to Section 6.04, each of the Securityholders, on its own behalf, and not on behalf of any other Shareholder, severally (and for greater certainty, not jointly with any other Securityholder) shall indemnify and save the Purchaser harmless for and from:

(a) any loss, damages or deficiencies suffered by the Purchaser as a result of any breach by such Securityholder of any representation, warranty or covenant on the part of such Securityholder contained in this Agreement or in any certificate or document delivered pursuant to or contemplated by this Agreement; and

(b) all claims, demands, costs and expenses, including legal fees, in respect of the foregoing.

A party entitled to and seeking indemnification pursuant to the terms of this Agreement (the "Indemnified Party") shall promptly give written notice to the party or parties, as applicable, responsible for indemnifying the Indemnified Party (the "Indemnifying Party") of any claim for indemnification pursuant to Sections 9.01, 9.02 and 9.03 (a "Claim", which term shall include more than one Claim). Such notice shall specify whether the Claim arises as a result of a claim by a person against the Indemnified Party (a "Third Party Claim") or whether the Claim does not so arise (a "Direct Claim"), and shall also specify with reasonable particularity (to the extent that the information is available):

(b) the amount of the Claim, or, if any amount is not then determinable, an approximate and reasonable estimate of the likely amount of the Claim.

(a) Direct Claims. With respect to Direct Claims, following receipt of notice from the Indemnified Party of a Claim, the Indemnifying Party shall have 30 days to make such investigation of the Claim as the Indemnifying Party considers necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying party the information relied upon by the Indemnified Party to substantiate the Claim. If the Indemnified Party and the Indemnifying Party agree at or prior to the expiration of such 30 day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim.

(b) Third Party Claims. With respect to any Third Party Claim, the Indemnifying Party shall have the right, at its own expense, to participate in or assume control of the negotiation, settlement or defence of such Third Party Claim and, in such event, the Indemnifying Party shall reimburse the Indemnified Party for all the Indemnified Party's out-of-pocket expenses incurred as a result of such participation or assumption. If the Indemnifying Party elects to assume such control, the Indemnified Party shall cooperate with the Indemnifying Party, shall have the right to participate in the negotiation, settlement or defence of such Third Party Claim at its own expense and shall have the right to disagree on reasonable grounds with the selection and retention of counsel, in which case counsel satisfactory to the Indemnifying Party and the Indemnified Party shall be retained by the Indemnifying Party. If the Indemnifying Party, having elected to assume such control, thereafter fails to defend any such Third Party Claim within a reasonable time, the Indemnified Party shall be entitled to assume such control and the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to such Third Party Claim.

The obligations of the Indemnifying Party to indemnify the Indemnified Party in respect of Claims shall also be subject to the following:

(a) without limiting the generality of Sections 9.01, 9.02 and 9.03, any Claim for breach of any representation, warranty or covenant shall be subject to Section 6.04;

(b) the Indemnifying Party's obligation to indemnify the Indemnified Party shall only apply to the extent that the Claims in respect of which the Indemnifying Party has given an indemnity, in the aggregate, exceed $5,000;

(c) notwithstanding anything to the contrary in this Agreement, the aggregate liability of an Indemnifying Party which is a Shareholder to any and all Indemnified Parties under this Article VIII shall be limited to the amount paid to such Indemnifying Party in respect of its Purchased Shares pursuant to Section 2.01; for greater certainty, no Shareholder shall be liable, in the aggregate, to any and all Indemnified Parties for any amount in excess of the value of its pro rata share of the Payment Shares;

(d) notwithstanding anything to the contrary in this Agreement, the aggregate liability of NASH or the Purchaser to any and all Indemnified Parties under this Article IX shall be limited to the value of the Payment Shares issuable under this Agreement;

(e) if any Third Party Claim is of a nature such that the Indemnified Party is required by applicable law to make a payment to any person (a "Third Party") with respect to such Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and thereafter seek reimbursement from the Indemnifying Party for any such payment. If any Indemnifying Party pays, or reimburses an Indemnified Party in respect of any Third Party Claim before completion of settlement negotiations or related legal proceedings, and the amount of any liability of the Indemnified Party under the Third Party Claim in respect of which such a payment was made, as finally determined, is less than the amount which was paid by the Indemnifying Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Party;

(f) except in the circumstance contemplated by Section 9.05, and whether or not the Indemnifying Party assumes control of the negotiation, settlement or defence of any Third Party Claim, the Indemnified Party shall not negotiate, settle, compromise or pay any Third Party Claim except with the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld);

(g) the Indemnified Party shall not permit any right of appeal in respect of any Third Party Claim to terminate without giving the Indemnifying Party notice and an opportunity to contest such Third Party Claim;

(h) the Indemnified Party and the Indemnifying Party shall cooperate fully with each other with respect to Third Party Claims and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available); and

(i) the provisions of this Article IX shall constitute the sole remedy available to a party against another party with respect to any and all breaches of any agreement, covenant, representation or warranty made by such other party in this Agreement.

Prior to the Termination Date, or the earlier termination of this Agreement, neither NASH nor the Shareholders shall, directly or indirectly, negotiate or deal with any party other than with the Purchaser relating to the sale or disposition of any part of the outstanding NASH Shares or assets of NASH, or solicit enquiries or provide information with respect to same. Notwithstanding the foregoing, nothing contained in this Agreement shall be interpreted to extend to the acts or omissions of any person acting in his or her capacity as a director or officer of NASH or otherwise to fetter the proper exercise of discretion of such person. In addition, nothing contained in this Agreement will prohibit, prevent or restrict NASH from furnishing or providing information in respect of or otherwise responding to or engaging in discussions or negotiations in respect of, an unsolicited Alternative Transaction not resulting from a breach of this Section 10.01, or the directors of NASH, in the fulfilment of their fiduciary duties, from supporting or facilitating any such unsolicited Alternative Transaction, or NASH or the Shareholders from completing any such Alternative Transaction, or entering into a definitive and binding agreement to effect such an Alternative Transaction, if directors of NASH determine in good faith, after consultation, to the extent considered appropriate by the directors, with its financial and legal advisors, that such unsolicited Alternative Transaction constitutes, or could reasonably be expected to lead to or result in, a transaction that would, if consummated in accordance with its terms, be more favourable to NASH or the Shareholders than the Transaction provided, however, that prior to taking such action, the directors of NASH shall have concluded, after considering applicable laws, and receiving advice of outside counsel, that such action would be a proper exercise of its fiduciary duties, or is otherwise required, under applicable laws, that it is appropriate that the directors take such action in order to properly discharge their fiduciary duties or that such action is otherwise required under applicable laws. In the event NASH or its Shareholders receive any form of offer or inquiry, NASH shall forthwith (in any event within one business day following receipt) notify the Purchaser of such offer or inquiry and provide the Purchaser with such details as it may request.

Prior to the Termination Date, or the earlier termination of this Agreement, the Purchaser shall not, directly or indirectly, negotiate or deal with any party other than NASH relating to an Alternative Transaction involving the Purchaser or the acquisition by the Purchaser of all or any part of the outstanding shares or assets or property of any other person, or solicit enquiries or provide information with respect to same, provided that nothing herein shall prevent the board of directors of the Purchaser from responding to an unsolicited offer in accordance with their fiduciary duties as directors.

Each of the Securityholders hereby severally and irrevocably appoints NASH as its agent and attorney to take any action that is required under the Agreement or to execute and deliver any documents on their behalf, including without limitation, for the purposes of all Closing matters (including without limitation, the receipt of certificates representing the Payment Shares or Replacement Warrants) and deliveries of documents and do and cause to be done all such acts and things as may be necessary or desirable in connection with the closing matters for the Transaction. Without limiting the generality of the foregoing, NASH may, on its own behalf and on behalf of the Securityholders, extend the Time of Closing, modify or waive any conditions as are contemplated herein, negotiate, settle and deliver the final forms of any documents that are necessary or desirable to give effect to the Transaction (other than any escrow agreements required that a Securityholder may be required to enter into), extend such time periods as may be contemplated herein or terminate this Agreement, in its absolute discretion, as it deems appropriate. Each of the Securityholders hereby acknowledges and agrees that any decision or exercise of discretion made by NASH under this Agreement, shall be final and binding upon the Securityholders so long as such decision or exercise was made in good faith. The Purchaser shall have no duty to enquire into the validity of any document executed or other action taken by NASH on behalf of the Securityholders pursuant to this Article XI.

Any notice, consent, waiver, direction or other communication required or permitted to be given under this Agreement (each, a "notice") shall be in writing shall be in writing addressed as follows:

or such other address as may be designated by notice given by either NASH or the Purchaser to the other in accordance with this Section 11.02. Each notice shall be personally delivered to the addressee or sent by e-mail to the addressee and a notice which is personally delivered or sent by email shall, if delivered or sent prior to 4:00 p.m. (local time of the recipient) on a Business Day, be deemed to be given and received on that day and, in any other case, be deemed to be given and received on the next Business Day. Any notice delivered to NASH in accordance with this Section 11.02 prior to the Time of Closing shall be deemed to have been delivered to each of the Shareholders. The previous sentence of this Section 11.02 shall not apply to a notice given as contemplated in Section 4.04 of the occurrence, or failure to occur, of any event or state of facts which would or would likely to cause any of the representations or warranties of any Shareholder to be untrue or inaccurate or result in the failure by any Shareholder to comply with or satisfy any covenant, condition or agreement, which notice shall not be deemed to have been received by such Shareholder unless delivered to the address of such Shareholder as reflected in the books of NASH (or after the Time of Closing, the books of the Purchaser). Any Shareholder may, from time to time, by notice given in accordance with this Section 11.02, designate or provide an address of such Shareholder for notices to be given after the Time of Closing.

Prior to Closing and, if the Transaction is not completed, at all times thereafter, each of the parties hereto will keep confidential and refrain from using all information obtained by it in connection with the transactions contemplated by this Agreement relating to any other party hereto, provided however that such obligation shall not apply to any information which was in the public domain at the time of its disclosure to a party or which subsequently comes into the public domain other than as a result of a breach of such party's obligations under this Section 11.03. For greater certainty, nothing contained herein shall prevent any disclosure of information which may be required pursuant to applicable laws or pursuant to an order in judicial or administrative proceedings or any other order made by any Governmental Authority.

No party may assign this Agreement or its rights or obligations hereunder without the prior written consent of the other parties hereto.

This Agreement shall be binding upon and shall enure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns.

No waiver of any provision of this Agreement will constitute a waiver of any other provision, nor will any waiver constitute a continuing waiver unless otherwise expressly provided.

This Agreement shall be governed by and construed and interpreted in accordance with the laws of the Province of British Columbia and the federal laws of Canada applicable therein and is to be treated in all respects as a British Columbia contract.

NASH shall be responsible for its costs and expenses incurred with respect to the transactions contemplated herein, which are comprised of its legal and accounting fees and disbursements relating to preparing this Agreement and related documents specifically relating to the transactions contemplated herein, it being acknowledged, that documentation in respect of the Transaction shall, to as great an extent as reasonably possible, be prepared by the Purchaser's counsel with the assistance of NASH as needed. If during the term of this Agreement, the Transaction does not successfully complete, then each party will be responsible for its own expenses incurred. If either party terminates the Transaction prior to the end of the term of this Agreement and for reasons not found in Article IV then 100% of the Transaction expenses incurred up to cancellation date shall be payable by the cancelling party.

(a) No director, officer, employee or agent of the Purchaser shall have any personal liability whatsoever to NASH or the Securityholders under this Agreement or any other document delivered in connection with the Transaction on behalf of the Purchaser.

(b) No director, officer, employee or agent of NASH (in such capacity) shall have any personal liability whatsoever to the Purchaser under this Agreement or any other document delivered in connection with the Transaction on behalf of NASH.

NASH and the Purchaser shall co-operate with the other in releasing information concerning this Agreement and the transactions contemplated herein, and shall furnish to and discuss with the other drafts of all press and other releases prior to publication. No press release or other public announcement concerning the proposed transactions contemplated by this Agreement will be made by any party hereto without the prior consent of the other parties, such consent not to be unreasonably withheld or delayed; provided that nothing contained herein shall prevent any party hereto at any time from furnishing any information to any Governmental Authority or to the public if so required by applicable law.

Each party will, upon request but without further consideration, from time to time promptly execute and deliver all further documents and take all further action necessary or appropriate to give effect to and perform the provisions and intent of this Agreement and to complete the transactions contemplated herein.

This Agreement, together with the documents required to be delivered pursuant to this Agreement, constitute the entire agreement among the parties hereto pertaining to the subject matter hereof and supersedes all prior agreements, understandings, negotiations, and discussions, whether oral or written, between the parties hereto with respect to the subject matter hereof including the letter agreement dated August 1, 2018 between the Purchaser and NASH (which letter agreement the Purchaser and NASH hereby agree is terminated). There are no representations, warranties, covenants or conditions with respect to the subject matter hereof except as contained in this Agreement and any document delivered pursuant to this Agreement.

No amendment of any provision of this Agreement will be binding on any party unless consented to in writing by such party.

In the event that any provision or part of this Agreement is determined by any court or other judicial or administrative body to be illegal, null, void, invalid or unenforceable, that provision shall be severed to the extent that it is so declared and the other provisions of this Agreement shall continue in full force and effect.

The rights and remedies of the parties under this Agreement are cumulative and in addition to and not in substitution for any rights or remedies provided by law.

RE: ACQUISITION OF SECURITIES OF BREATHTEC PURSUANT TO SHARE EXCHANGE AGREEMENT (the "Securities")

Capitalized terms not specifically defined in this certification have the meaning ascribed to them in the Share Exchange Agreement to which this Schedule is attached. In the event of a conflict between the terms of this certification and such Share Exchange Agreement, the terms of this certification shall prevail.

In addition to the covenants, representations and warranties contained in the Share Exchange Agreement to which this Schedule is attached, the undersigned (the "U.S. Securityholder") covenants, represents and warrants to Breathtec that:

(a) It has such knowledge, skill and experience in financial, investment and business matters as to be capable of evaluating the merits and risks of an investment in the Securities and it is able to bear the economic risk of loss of its entire investment. To the extent necessary, the U.S. Securityholder has retained, at his or her own expense, and relied upon, appropriate professional advice regarding the investment, tax and legal merits and consequences of the Share Exchange Agreement and owning the Securities.

(b) Breathtec has provided to it the opportunity to ask questions and receive answers concerning the terms and conditions of the offering and it has had access to such information concerning Breathtec as it has considered necessary or appropriate in connection with its investment decision to acquire the Securities, including access to Breathtec's public filings available on the Internet at www.sedar.com, and that any answers to questions and any request for information have been complied with to the U.S. Securityholder's satisfaction.

(c) It is acquiring the Securities for its own account, for investment purposes only and not with a view to any resale or distribution and, in particular, it has no intention to distribute either directly or indirectly the Securities in the United States or to, or for the account or benefit of, a U.S. Person or a person in the United States; provided, however, that this paragraph shall not restrict the U.S. Securityholder from selling or otherwise disposing of the Securities pursuant to registration thereof pursuant to the U.S. Securities Act and any applicable state securities laws or under an exemption from such registration requirements.

(d) The address of the U.S. Securityholder set out in the signature block below is the true and correct principal address of the U.S. Securityholder and can be relied on by Breathtec for the purposes of state blue-sky laws and the U.S. Securityholder has not been formed for the specific purpose of purchasing the Securities.

(e) It understands (i) the Securities have not been and will not be registered under the U.S. Securities Act or the securities laws of any state of the United States; and (ii) the offer and sale contemplated hereby is being made in reliance on an exemption from such registration requirements in reliance on Rule 506(b) of Regulation D and/or Section 4(a)(2) of the U.S. Securities Act.

(i) an "accredited investor" as defined in Rule 501(a) of Regulation D of the U.S. Securities Act by virtue of meeting one of the following criteria set forth in Appendix A hereto (please hand-write your initials on the appropriate lines on Appendix A), which Appendix A forms an integral part hereof; or

(ii) is not an "accredited investor" as defined in Rule 501(a) of Regulation D of the U.S. Securities Act, has a pre-existing substantive relationship with Breathtec, and has completed Appendix B hereto, which forms an integral part hereof.

(g) The U.S. Securityholder has not purchased the Securities as a result of any form of "general solicitation" or "general advertising" (as those terms are used in Regulation D under the U.S. Securities Act), including advertisements, articles, press releases, notices or other communications published in any newspaper, magazine or similar media or on the Internet, or broadcast over radio or television, or the Internet or other form of telecommunications, including electronic display, or any seminar or meeting whose attendees have been invited by general solicitation or general advertising.

(h) It acknowledges that the Securities will be "restricted securities", as such term is defined in Rule 144(a)(3) under the U.S. Securities Act, and may not be offered, sold, pledged, or otherwise transferred, directly or indirectly, without prior registration under the U.S. Securities Act and applicable state securities laws, and it agrees that if it decides to offer, sell, pledge or otherwise transfer, directly or indirectly, any of the Securities, it will not offer, sell or otherwise transfer, directly or indirectly, the Securities except:

(ii) outside the United States in an "offshore transactions" meeting the requirements of Rule 904 of Regulation S under the U.S. Securities Act, if available, and in compliance with applicable local laws and regulations;

(iii) in compliance with the exemption from the registration requirements under the U.S. Securities Act provided by Rule 144 thereunder, if available, and in accordance with any applicable state securities or "blue sky" laws; or

(iv) in a transaction that does not require registration under the U.S. Securities Act or any applicable state securities laws governing the offer and sale of securities,

and, in the case of each of (iii) and (iv) above, it has prior to such sale furnished to Breathtec and opinion of counsel in form and substance reasonably satisfactory to Breathtec stating that such transaction is exempt from registration under applicable securities laws and that the legend referred to in paragraph (k) below may be removed.

(i) It understands and agrees that the Securities may not be acquired in the United States or by a U.S. Person or on behalf of, or for the account or benefit of, a U.S. Person or a person in the United States unless registered under the U.S. Securities Act and any applicable state securities laws or unless an exemption from such registration requirements is available.

(j) It acknowledges that it has not purchased the Securities as a result of, and will not itself engage in, any "directed selling efforts" (as defined in Regulation S under the U.S. Securities Act) in the United States in respect of the Securities which would include any activities undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States for the resale of the Securities.

(k) The certificates representing the Securities issued hereunder, as well as all certificates issued in exchange for or in substitution of the foregoing, until such time as the same is no longer required under the applicable requirements of the U.S. Securities Act or applicable state securities laws and regulations, will bear, on the face of such certificate, the following legend:

"THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF BREATHTEC VENTURES CORP. (THE "COMPANY") THAT SUCH SECURITIES MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH ALL LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSE (C) OR (D), THE SELLER FURNISHES TO THE COMPANY AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY TO SUCH EFFECT. THE PRESENCE OF THIS LEGEND MAY IMPAIR THE ABILITY OF THE HOLDER HEREOF TO EFFECT "GOOD DELIVERY" OF THE SECURITIES REPRESENTED HEREBY ON A CANADIAN STOCK EXCHANGE."

provided, that if the Securities are being sold outside the United States in compliance with the requirements of Rule 904 of Regulation S in circumstances where Rule 905 of Regulation S does not apply, and in compliance with Canadian local laws and regulations, the legend set forth above may be removed by providing an executed declaration to the registrar and transfer agent of Breathtec, in substantially the form set forth as Appendix C attached hereto (or in such other forms as Breathtec may prescribe from time to time) and, if requested by Breathtec or the transfer agent, an opinion of counsel of recognized standing in form and substance reasonably satisfactory to Breathtec and the transfer agent to the effect that such sale is being made in compliance with Rule 904 of Regulation S; and provided, further, that, if any Securities are being sold otherwise than in accordance with Regulation S and other than to Breathtec, the legend may be removed by delivery to the registrar and transfer agent and Breathtec of an opinion of counsel, of recognized standing reasonably satisfactory to Breathtec, that such legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws.

(l) It understands and agrees that there may be material tax consequences to the U.S. Securityholder of an acquisition, holding or disposition of any of the Securities. Breathtec gives no opinion and makes no representation with respect to the tax consequences to the U.S. Securityholder under United States, state, local or foreign tax law of the undersigned's acquisition, holding or disposition of such Securities. In particular, no determination has been made whether Breathtec will be a "passive foreign investment company" within the meaning of Section 1297 of the United States Internal Revenue Code of 1986, as amended.

(m) It consents to Breathtec making a notation on its records or giving instructions to any transfer agent of Breathtec in order to implement the restrictions on transfer set forth and described in this certification and the Share Exchange Agreement.

(n) It understands that (i) Breathtec may be deemed to be an issuer that is, or that has been at any time previously, an issuer with no or nominal operations and no or nominal assets other than cash and cash equivalents (a "Shell Company"), (ii) if Breathtec is deemed to be, or to have been at any time previously, a Shell Company, Rule 144 under the U.S. Securities Act may not be available for resales of the Securities, and (iii) Breathtec is not obligated to make Rule 144 under the U.S. Securities Act available for resales of the Securities.

(o) It understands and agrees that the financial statements of Breathtec have been prepared in accordance with International Financial Reporting Standards and therefore may be materially different from financial statements prepared under U.S. generally accepted accounting principles and therefore may not be comparable to financial statements of United States companies.

(p) It understands and acknowledges that Breathtec is incorporated outside the United States, consequently, it may be difficult to provide service of process on Breathtec and it may be difficult to enforce any judgment against Breathtec.

(q) It understands that Breathtec does not have any obligation to register the Securities under the U.S. Securities Act or any applicable state securities or "blue-sky" laws or to take action so as to permit resales of the Securities. Accordingly, the U.S. Securityholder understands that absent registration, it may be required to hold the Securities indefinitely. As a consequence, the U.S. Securityholder understands it must bear the economic risks of the investment in the Securities for an indefinite period of time.

The foregoing representations contained in this certificate are true and accurate as of the date of this certificate and will be true and accurate as of the Time of Closing. If any such representations shall not be true and accurate prior to the Time of Closing, the undersigned shall give immediate written notice of such fact to Breathtec prior to the Time of Closing.

In addition to the covenants, representations and warranties contained in the Share Exchange Agreement and the Schedule "D" to which this Appendix is attached, the undersigned (the "U.S. Securityholder") covenants, represents and warrants to Breathtec that the U.S. Securityholder is an "accredited investor" as defined in Rule 501(a) of Regulation D of the U.S. Securities Act by virtue of meeting one of the following criteria (please hand-write your initials on the appropriate lines):

In addition to the covenants, representations and warranties contained in the Share Exchange Agreement and the Schedule "D" to which this Appendix is attached, the undersigned (the "U.S. Securityholder") covenants, represents and warrants to Breathtec Biomedical, Inc. (also referred to herein as the "Company") that the U.S. Securityholder understands that the Securities have not been and will not be registered under the U.S. Securities Act and that the offer and sale of the Securities to the U.S. Securityholder contemplated by the Share Exchange Agreement is intended to be a private offering pursuant to Section 4(a)(2) of the U.S. Securities Act.

Your answers will at all times be kept strictly confidential. However, by signing this suitability questionnaire (the "Questionnaire") the U.S. Securityholder agrees that the Company may present this Questionnaire to such parties as may be appropriate if called upon to verify the information provided or to establish the availability of an exemption from registration of the private offering under the federal or state securities laws or if the contents are relevant to issue in any action, suit or proceeding to which the Company is a party or by which it is or may be bound.

A close personal friend is an individual who has known the director, senior officer or control person for a sufficient period of time to be in a position to assess the capabilities and trustworthiness of the director, senior officer or control person.

A close business associate is an individual who has had sufficient prior business dealings with the director, senior officer or control person to be in a position to assess the capabilities and trustworthiness of the director, senior officer or control person.
