The calculation of the 27.2% beneficial ownership is based on (i) 5,354,097 Shares beneficially owned by the Voting Shareholders (as defined herein) that are parties to certain Voting Agreements, dated as of August 2, 2017, and (ii) 19,675,128 Shares reported outstanding as of August 2, 2017 (as set forth in the Merger Agreement referred to in this Schedule 13D).

Purpose of Transaction.

Agreement and Plan of Merger

On August 2, 2017, Sierra Wireless, Wireless Acquisition Sub, Inc., a Delaware corporation and direct, wholly-owned subsidiary of Sierra Wireless (“Merger Sub”), and the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will merge with and into the Issuer, with the Issuer surviving as a wholly-owned subsidiary of Sierra Wireless (the “Merger”). The Merger Agreement was unanimously approved and adopted by the boards of directors of each of the Issuer and Sierra Wireless.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), the Issuer’s shareholders will have the right to receive 0.1800 common shares, no par value, of Sierra Wireless (“Sierra Common Stock”) for each Share of the Issuer (such consideration, the “Merger Consideration”). Additionally, each outstanding restricted stock unit, in-the-money option and in-the-money stock appreciation right of the Issuer will be cancelled in exchange for the right to receive the Merger Consideration in accordance with the terms of the Merger Agreement. Subject to certain exceptions specified in the Merger Agreement, if exercised following notice of the Merger, each outstanding warrant issued by the Issuer (with the exception of that certain Warrant, dated as of June 7, 2017, issued by the Issuer to HCP-FVF, LLC) will be cancelled in exchange for the right to receive the Merger Consideration or, if not exercised, will be cancelled at the Effective Time.

The Merger Agreement contains customary representations and warranties from each of the Issuer and Sierra Wireless, and each party to the Merger Agreement has agreed to customary covenants, including, among others, covenants relating to (1) the conduct of the Issuer’s and Sierra Wireless’ businesses during the interim period between the execution of the Merger Agreement and the Effective Time, (2) the obligation of the Issuer to call a meeting of its shareholders to adopt the Merger Agreement, and, subject to certain exceptions, to recommend that its shareholders adopt the Merger Agreement and (3) the Issuer’s non-solicitation obligations relating to alternative acquisition proposals. Each of the Issuer and Sierra Wireless has also agreed to apply for, or otherwise seek, and use its respective commercially reasonable efforts to obtain, all consents and approvals of governmental entities required to be obtained by it for the consummation of the transactions contemplated by the Merger Agreement.

The completion of the Merger is subject to customary conditions, including (1) the adoption of the Merger Agreement by the Issuer’s shareholders, (2) the receipt of conditional approval of the shares of Sierra Common Stock to be issued in the Merger for listing on the Toronto Stock Exchange, subject only to customary post-closing deliverables, and on The NASDAQ Global Market, subject only to official notice of issuance, (3) the expiration or early termination of all applicable waiting periods applicable to the consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (4) the effectiveness of the registration statement on Form F-4 by the Securities and Exchange Commission (the “SEC”) for the Sierra Common Stock to be issued in the Merger, (5) the absence of any order, injunction or other legal restraint preventing the completion of the Merger or making the completion of the Merger illegal and (6) the absence of any pending legal proceeding instituted by any governmental entity seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated by the Merger Agreement.

Each party’s obligation to complete the Merger is also subject to certain additional customary conditions, including (1) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (2) performance in all material respects by the other party of its obligations under the Merger Agreement, (3) the absence of a material adverse effect with respect to the other party and (4) receipt by such party of a tax opinion to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement also provides certain termination rights for each of the Issuer and Sierra Wireless and further provides that a termination fee equal to 3.75% of the aggregate equity value of the Merger as of the date of the Merger Agreement will be payable by the Issuer upon termination of the Merger Agreement under certain circumstances specified in the Merger Agreement. In addition, upon termination of the Merger Agreement by Sierra Wireless or the Issuer as a result of the Issuer’s shareholders not approving the transaction or upon termination of the Merger Agreement by Sierra Wireless as a result of the Issuer’s fraud or willful and material breach of a representation, warranty or covenant, the Issuer may be required to reimburse Sierra Wireless for its out-of-pocket costs and expenses incurred in connection with the Merger in an amount not to exceed $850,000 in the event of a no vote and $2 million in the event of fraud or a willful and material breach.

CUSIP NO. 67053A 10 2

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties will not survive consummation of the Merger and were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Issuer or Sierra Wireless, their respective affiliates and their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Issuer, Sierra Wireless, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the Registration Statement on Form F-4 that will include a proxy statement of the Issuer and a prospectus of Sierra Wireless, as well as each of the Issuer’s and Sierra Wireless’ public filings. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of each of the Issuer and Sierra Wireless or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in each of the Issuer’s and Sierra Wireless’ public disclosures.

The foregoing summary of the Merger Agreement, and the transactions contemplated thereby, does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, filed as Exhibit 1 to this Schedule 13D and incorporated herein by reference.

Voting Agreements

Simultaneous with the execution of the Merger Agreement, Sierra Wireless entered into voting agreements (the “Voting Agreements”), dated as of August 2, 2017, with certain shareholders of the Issuer, including (i) Gwynedd Resources Ltd., (ii) VIEX Opportunities Fund, LP – Series One, VIEX GP, LLC, VIEX Special Opportunities Fund II, LP, VIEX Special Opportunities GP II, LLC, VIEX Special Opportunities Fund III, LP, VIEX Special Opportunities GP III, LLC, VIEX Capital Advisors, LLC and Eric Singer (collectively, “Viex”), (iii) Tony G.

The Voting Agreements generally require, subject to certain exceptions, such Voting Shareholders to vote, or cause or direct to be voted, all of the Shares beneficially owned by them to approve and adopt the Merger Agreement and the Merger and against any acquisition proposal or any other action, agreement or transaction that would reasonably be expected to impede or delay the Merger. Each Voting Shareholder also agreed to certain transfer restrictions with respect to the Shares held by such Voting Shareholder. Pursuant to the terms of such Voting Agreements, the Voting Agreements generally will terminate upon, among other things, (i) any termination of the Merger Agreement, (ii) once the Issuer’s shareholder approval of the Merger is obtained or (iii) upon certain changes to the terms of the Merger Agreement that decrease the amount or change the form of consideration received by the Issuer’s shareholders in the Merger.

Pursuant to its Voting Agreement with Sierra Wireless, if the Merger is completed, Viex agreed not to take any of the following actions from the completion of the Merger until June 30, 2019: (i) purchase or otherwise acquire beneficial ownership of any shares of Sierra Common Stock, other than those shares of Sierra Common Stock that Viex receives as consideration in the Merger, (ii) seek or encourage any person to submit nominations, or engage in the solicitation of proxies or consents, for the election or removal of Sierra Wireless directors, (iii) otherwise act to seek control of or influence Sierra Wireless’ board of directors, management or policies, or (iv) take any actions that question the validity or effectiveness of Sierra Wireless’ shareholder rights plan or any securities issued pursuant thereto. In addition, each of Sierra Wireless and Viex also agreed, if the Merger is completed, to abide by mutual non-disparagement obligations from the completion of the Merger until June 30, 2019.

The foregoing summaries of the Voting Agreements, and the transactions contemplated thereby, do not purport to be complete and are subject to, and qualified in their entirety by, the Voting Agreements, filed as Exhibits 2, 3 and 4 to this Schedule 13D and incorporated herein by reference.

Information regarding the Voting Shareholders’ beneficial ownership is based upon information regarding the number of shares subject to the Voting Agreements. Sierra Wireless disclaims any beneficial ownership of such Shares, and nothing herein shall be deemed to be an admission by Sierra Wireless as to the beneficial ownership of such Shares. To Sierra Wireless’ knowledge, no Shares are beneficially owned by any of the persons listed on Schedule A.

Notwithstanding the foregoing, however, Sierra Wireless (i) is not entitled to any rights as a stockholder of the Issuer with respect to any Shares and (ii) has no power to vote, direct the voting of, dispose of, or direct the disposal of, any Shares other than the power provided pursuant to the Voting Agreements. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that Sierra Wireless is the beneficial owner of any securities of the Issuer (including, without limitation, the Shares owned by the Voting Shareholders) for purposes of Section 13(d) or 16 of the Exchange Act or for any other purpose and such beneficial ownership is hereby expressly disclaimed.

(c)

Except as described in this Schedule 13D, no transactions in the Shares were effected during the past sixty (60) days by Sierra Wireless, or, to the best of the knowledge of Sierra Wireless, by any of the other persons listed on Schedule A hereto.

(d)

To the knowledge of Sierra Wireless, no person other than the Voting Shareholders (including Gwynedd Resources Ltd., VIEX Special Opportunities Fund II, LP, VIEX Special Opportunities GP II, LLC, VIEX Capital Advisors, LLC and Eric Singer, each of which beneficially owns in excess of 5% of the outstanding Shares of the Issuer) has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares subject to the Voting Agreement.

(e)

Not applicable.

As stated above, the above descriptions of the Merger Agreement and Voting Agreements are not intended to be complete and are qualified in their entirety by reference to the Merger Agreement and the Voting Agreements, copies of which are listed as Exhibits hereto and are incorporated herein by reference.
