On September 16, 2011, the Board of Directors (the “Board”) of West Corporation (the “Company”) adopted the West Corporation Senior Management Retention Plan for the benefit of certain executive officers and other key employees of the Company (the “Senior Management Retention Plan”). The following summary is qualified in its entirety by reference to the text of the Senior Management Retention Plan, a copy of which is filed as an exhibit hereto.

Under the terms of the Senior Management Retention Plan, if a participant in the plan continues employment through October 24, 2011, the participant shall be eligible for a retention bonus in an amount designated by the Board. If the participant’s employment is terminated by the Company without Cause (as defined in the Senior Management Retention Plan) prior to October 24, 2011, then the participant will receive the retention bonus in a lump sum cash payment.

If a participant ceases to be employed by the Company prior to October 24, 2012 other than on account of such participant’s death, then such participant shall be obligated to repay all or a portion of the retention bonus as follows. If, prior to October 24, 2012, a participant’s employment is terminated by the Company for Cause or voluntarily by the participant, then such participant shall be obligated to pay back to the Company 100% of such participant’s retention bonus. If, prior to October 24, 2012, a participant’s employment with the Company is terminated for any reason other than by the Company for Cause or voluntary termination by the participant, then such participant shall be obligated to pay back to the Company a pro rata portion of the participant’s retention bonus (based on days employed during the twelve month period beginning October 25, 2011). Any retention bonus required to be repaid pursuant to the terms of the Senior Management Retention Plan shall be paid within three business days following the participant’s termination of employment.

Participants in the Senior Management Retention Plan include Thomas B. Barker, Nancee R. Berger, Paul M. Mendlik, and Steven M. Stangl. Subject to the terms of the Senior Management Retention Plan, Mr. Barker, Ms. Berger and Messrs. Mendlik and Stangl are eligible to receive retention bonuses of $2.1 million, $1.0 million, $250,000 and $250,000, respectively.
