Item 5.02.                                        Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Sonus Networks, Inc. (the “Company”) held its annual meeting of stockholders on June 9, 2017 (the “Annual Meeting”).  At the Annual Meeting, the Company’s stockholders approved an amendment and restatement to the Sonus Networks, Inc. Amended and Restated Stock Incentive Plan (the “Plan”) to, among other things:

·                  Increase the aggregate number of shares of the Company’s common stock authorized for issuance under the Plan by an additional 900,000 shares;

·                  Make the Plan more explicit by providing that any dividends on unvested restricted stock or with respect to shares of common stock granted under an other stock unit award will be paid to a participant only if and when such shares become free from the restrictions on transferability and forfeitability that apply to such shares and that any dividend equivalents with respect to restricted stock units and other stock unit awards will be subject to the same vesting conditions and restrictions on transfer and forfeitability applicable to the underlying award with respect to which it is paid.  No interest will be paid on any such dividends or dividend equivalents;

·                  Explicitly require a participant who accepts an award under the Plan to be bound by any clawback policy that the Company has in effect or may adopt in the future; and

·                  Eliminate the requirement that each share of stock subject to an award of restricted stock, restricted stock units, performance awards or other stock unit awards (collectively, “full value awards”) be counted against the share reserve as 1.50 shares for every 1 share subject to such award.  This change applies to all full value awards from and after June 9, 2017, the date of the Annual Meeting.  Shares of common stock subject to awards that were granted under any prior ratio that applied at the time such awards were granted will continue to return to the Plan upon forfeiture of such awards at the previous applicable ratio.

This amendment and restatement of the Plan had previously been approved by the Company’s Board of Directors subject to stockholder approval.  The provisions of the Plan are described in the Company’s definitive proxy statement on Schedule 14A filed with the U.S. Securities and Exchange Commission on April 28, 2017 (the “Proxy Statement”) under “Proposal Two — Approval of an Amendment and Restatement of Sonus Networks’ Stock Incentive Plan.”  The foregoing summary of the Plan is qualified in its entirety by reference to the complete text of the Plan, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
