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

West Corporation Amended and Restated 2013 Long-Term Incentive Plan

At the 2014 annual meeting of stockholders of West Corporation (the “Company”) held on May 13, 2014 (the “2014 Annual Meeting”), the Company’s stockholders approved the performance measures in the West Corporation Amended and Restated 2013 Long-Term Incentive Plan (the “Plan”), which had been previously approved by the Company’s board of directors (the “Board of Directors”), subject to stockholder approval.

Stockholders approved the performance measures under the Plan so that certain compensation paid under the Plan may qualify as performance-based compensation in accordance with Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”). Stockholders were not asked to approve an increase in the number of shares available under the Plan. The Plan allows for the grant of performance-based compensation. The grant, vesting, crediting and/or payment of performance-based compensation, if any, is based or conditioned on the achievement of objective performance measures established by the Compensation Committee of the Board of Directors (the “Compensation Committee”). The performance measures to be used under the Plan will be one or more of a number of corporate-wide or subsidiary, division, operating unit or individual measures, stated in either absolute terms or relative terms, such as rates of growth or improvement. Under the Plan, the Company may grant: (i) nonqualified stock options; (ii) incentive stock options; (iii) stock appreciation rights; (iv) restricted stock and restricted stock units; and (v) performance units (collectively, “Awards”).

The purposes of the Plan are to (i) align the interests of the Company’s stockholders and those eligible for Awards, (ii) attract and retain directors, officers, other employees and consultants, and (iii) motivate such persons to act in the long-term interests of the Company and its stockholders. The Compensation Committee administers the Plan and will designate the eligible award recipients under the Plan. Officers, other employees, consultants and non-employee directors of the Company and its subsidiaries and persons expected to become any of the foregoing are eligible to participate in the Plan, in the sole discretion of the Compensation Committee.

The Plan initially reserved 8,500,000 shares of Company common stock for the issuance of Awards. In the event that any outstanding Award expires or terminates without the issuance of shares or is otherwise settled for cash, the shares allocable to such Award, to the extent of such expiration or termination of such Award or settlement for cash, will again be available for issuance. The number of performance-based awards granted under the Plan in any year is subject to the Compensation Committee’s discretion.

A summary of the Plan, including the performance measures, can be found on pages 41 through 44 of the definitive proxy statement for the 2014 Annual Meeting, filed with the Securities and Exchange Commission on April 11, 2014 (the “2014 Proxy Statement”), which summary is incorporated herein by reference. That summary and the foregoing description of the Plan are qualified in their entirety by reference to the text of the Plan, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

West Corporation Amended and Restated Executive Incentive Plan

At the 2014 Annual Meeting, the Company’s stockholders also approved the West Corporation Amended and Restated Executive Incentive Plan (the “Executive Incentive Plan”), which had been previously approved by the Board of Directors, subject to stockholder approval.

The Executive Incentive Plan, as approved, is intended to qualify for exemption under Section 162(m) of the Internal Revenue Code of 1986, as amended. The purpose of the Executive Incentive Plan is to (i) attract, motivate and retain officers of the Company and its subsidiaries and divisions who have significant responsibility for the growth and long-term success of the Company by providing them with the opportunity to earn incentive payments based upon the extent to which specified performance goals have been achieved or exceeded during a performance period and (ii) provide for the payment of other special bonus awards. The Executive Incentive Plan is administered by the Compensation Committee.

All officers of the Company and its subsidiaries and divisions may be designated for participation in the Executive Incentive Plan and eligible to receive incentive awards based on the achievement of objective performance goals for performance periods commencing on or after January 1, 2015, subject to any other terms and conditions established by the Compensation Committee for each performance period. The Compensation Committee will designate the eligible officers who will participate in the Executive Incentive Plan for a specified performance period. A participant may receive an award under the Executive Incentive Plan based upon achievement of a performance goal or goals using one or more objective corporate-wide or subsidiary, division, operating unit or individual measures. Any awards granted under the Executive Incentive Plan will be determined by the Compensation Committee.

A summary of the Executive Incentive Plan can be found on pages 44 through 46 of the 2014 Proxy Statement, which summary is incorporated herein by reference. That summary and the foregoing description of the Executive Incentive Plan are qualified in their entirety by reference to the text of the Executive Incentive Plan, which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 5.07. Submission of Matters to a Vote of Security Holders.
