Item 1.01. Entry into a Material Definitive Agreement.
Merger Agreement
On July 26, 2017, ShoreTel, Inc., a Delaware corporation ("
ShoreTel
") entered into a definitive Agreement and Plan of Merger (the "
Merger Agreement
") with Mitel US Holdings, Inc., a Delaware corporation ("
Parent
"), Shelby Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent ("
Merger Sub
") and, with respect to certain obligations set forth in the Merger Agreement, Mitel Networks Corporation, a Canadian corporation ("
Guarantor
").
Pursuant to and subject to the terms and conditions of the Merger Agreement, Merger Sub will commence an all-cash tender offer (the "
Offer
") for any and all of ShoreTel's outstanding shares of common stock, par value $0.001 per share (the "
Shares
"), at a purchase price of $7.50 per Share (the "
Offer Price
"), net to the seller in cash, without interest, and subject to any required withholding of taxes.  Under the Merger Agreement, Merger Sub is required to commence the Offer within 15 business days after the date of the Merger Agreement.  The Offer will remain open for a minimum of 21 business days from the date of commencement.
The obligation of Merger Sub to purchase Shares tendered in the Offer is subject to specified closing conditions, including (i) immediately prior to the expiration of the Offer, a number of Shares must have been validly tendered and not validly withdrawn that, when added to the number of Shares (if any) then owned by Merger Sub, equals at least one Share more than half of all Shares then outstanding (the "
Minimum Condition
"), (ii) the absence of injunctions or other legal restraints preventing the consummation of the Offer or the Merger (as defined below), (iii) the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and Telecom Approvals (as defined in the Merger Agreement) have been obtained, (iv) the accuracy of the representations and warranties made by ShoreTel in the Merger Agreement, subject to specified materiality qualifications, including ShoreTel's representation that it will have a minimum cash balance as of the Expiration Date, (v) compliance by ShoreTel with its covenants in the Merger Agreement in all material respects, (vi) the absence of a "Company Material Adverse Effect" (as defined in the Merger Agreement) on ShoreTel since the date of the Merger Agreement, (vii) the completion of a specified marketing period for the debt financing (the "
Marketing Period
") Parent and Merger Sub are using to fund the aggregate Offer Price to be paid to tendering holders upon closing the Offer and to certain other holders upon closing the Merger (the "
Merger Consideration
") and (viii) the other conditions set forth in Annex I to the Merger Agreement.
Following the completion of the Offer, subject to the absence of injunctions or other legal restraints preventing the consummation of the Merger, Merger Sub will merge with and into ShoreTel, with ShoreTel surviving the merger as a wholly owned subsidiary of Parent (the "
Surviving Corporation
"), pursuant to the procedure provided for under Section 251(h) of the Delaware General Corporation Law (the "
Merger
").  The Merger will be effected as soon as practicable following the acceptance for payment by Merger Sub of Shares validly tendered and not withdrawn in the Offer, without a vote on the adoption of the Merger Agreement by ShoreTel stockholders.
At the effective time of the Merger (the "
Effective Time
"), each issued and outstanding Share (other than Shares owned by (i) ShoreTel, or any subsidiary of ShoreTel, Parent, Merger Sub or Guarantor, which Shares will be canceled and will cease to exist or (ii) stockholders who validly exercise appraisal rights under Delaware law with respect to such Shares) will be converted into the right to receive an amount in cash equal to the Offer Price, without interest, subject to any required withholding taxes.
Pursuant to the terms of the Merger Agreement, (i) each ShoreTel stock option that is vested as of immediately prior to the Effective Time (including those which accelerate pursuant to employment agreements, retention agreements or other equity agreements or plans or as specified in the Merger Agreement) will be cancelled in exchange for an amount in cash equal to the Offer Price, less the option exercise price, (ii) each other ShoreTel stock option will be cancelled for no consideration, (iii) each ShoreTel restricted stock unit that is vested as of immediately prior to the Effective Time (including those which accelerate pursuant to employment agreements, retention agreements or other equity agreements or plans or as specified in the Merger Agreement) will be cancelled in exchange for an amount in cash equal to the Offer Price and (iv) each other ShoreTel restricted stock unit will be cancelled for no consideration.  ShoreTel's Employee Stock Purchase Plan will be suspended on the date of the Merger Agreement, and will be terminated upon the consummation of the Merger pursuant to the terms of the Merger Agreement.
Pursuant to and subject to the terms and conditions of the Merger Agreement, ShoreTel has agreed, among other things, (i) to carry on its business in the ordinary course during the period between the execution of the Merger Agreement and the consummation of the Merger; (ii) subject to certain customary exceptions set forth in the Merger Agreement to permit ShoreTel's board of directors to comply with its fiduciary duties, to recommend that ShoreTel's stockholders accept the Offer and tender all of their shares pursuant to the Offer; (iii) not to solicit alternative acquisition proposals and (iv) to certain restrictions on its ability to respond to any unsolicited acquisition proposals.  The Merger Agreement also contains customary representations, warranties and covenants of each of ShoreTel, Parent and Merger Sub.
The Merger Agreement contains certain customary termination rights for both Parent and ShoreTel, including, among others, by either Parent or ShoreTel upon the failure of the Offer conditions to be satisfied or validly waived on or before November 23, 2017 (the "
Termination
Date
").
Upon termination of the Merger Agreement under specified circumstances, including (i) a termination by ShoreTel to enter into an agreement for an alternative transaction that constitutes a "Superior Proposal" (as defined in the Merger Agreement) or (ii) a termination by Parent due to a change in the ShoreTel board of directors' recommendation that ShoreTel's stockholders accept the Offer and tender all of their shares pursuant to the Offer, ShoreTel is required to pay Parent a termination fee of $24,500,000.  In addition, ShoreTel is required to pay Parent and Merger Sub an expense reimbursement of up to $6.0 million if the Merger Agreement is terminated (i) by either ShoreTel or Parent in the event that the Offer Acceptance Time (as defined in the Merger Agreement) has not occurred on or before the Termination Date as a result of the failure of the Minimum Condition to be satisfied, subject to certain rights of Parent to extend the Termination Date in certain circumstances, or (ii) by Parent if ShoreTel is in breach of the Merger Agreement.
The Merger Agreement also provides that Parent will be required to pay ShoreTel a termination fee of $30 million in the event that ShoreTel terminates the Merger Agreement because Merger Sub, after the satisfaction of the Offer conditions and the completion of the Marketing Period, has not accepted for payment the Shares tendered in the Offer within three business days following the expiration of the Offer, subject to certain rights of Merger Sub to extend the Expiration Time. In this circumstance, payment of the termination fee constitutes ShoreTel's sole and exclusive monetary remedy.
Parent has obtained debt financing commitments from Bank of Montreal, N.A. ("
BMO
") and BMO acting through its trade name BMO Capital Markets Corp., Citizens Bank, N.A., HSBC Bank Canada and Canadian Imperial Bank of Commerce to fund the transactions contemplated by the Merger Agreement. The Merger Agreement requires Parent to use commercially reasonable efforts to obtain the financing on the terms and conditions described in the financing commitments.
The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the actual terms of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference.  The Merger Agreement has been included to provide investors with information regarding its terms and is not intended to provide any financial or other factual information about ShoreTel, Parent or Merger Sub. In particular, the representations, warranties and covenants contained in the Merger Agreement (i) were made only for purposes of that agreement and as of specific dates, (ii) were made solely for the benefit of the parties to the Merger Agreement, (iii) may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement rather than establishing those matters as facts and (iv) may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors.  Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by Parent or ShoreTel.  Accordingly, investors should read the representations and warranties in the Merger Agreement not in isolation but only in conjunction with the other information about Parent or ShoreTel and their respective subsidiaries that the respective companies include in reports, statements and other filings they make with the U.S. Securities and Exchange Commission (the "
SEC
").
Tender Support Agreements
In connection with the execution of the Merger Agreement, the directors and executive officers of ShoreTel (collectively, the "
Stockholders
") have each entered into a Tender Support Agreement, dated as of July 26, 2017, with Parent and Merger Sub (each, a "
Support Agreement
").  Subject to the terms and conditions of the Support Agreements, each Stockholder has agreed, among other things, to tender his or her Shares into the Offer, and, subject to certain exceptions, not to transfer their shares that are subject to the Support Agreement.  The Support Agreement will terminate with respect to each Stockholder upon the first to occur of (i) the mutual written consent of Parent and such Stockholder, (ii) termination of the Merger Agreement in accordance with its terms, (iii) the consummation of the Merger, (iv) entry into an amendment or modification of the Offer or the Merger Agreement that results in a decrease in the Offer Price or a change in the form of consideration payable to the Stockholders or (v) the withdrawal or termination of the Offer by Merger Sub or the expiration of the Offer without acceptance for payment of the Shares tendered by the Stockholders.
The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the Support Agreement, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.
