West Corporation Commences Tender Offer and Consent Solicitation

for its 8.625% Senior Notes due 2018 and Commences Tender Offer for

up to $200 million of its 7.875% Senior Notes due 2019

OMAHA, NE, June 17, 2014 – West Corporation today announced that it is commencing a tender offer to purchase any and all of its outstanding $500 million in aggregate principal amount of 8.625% Senior Notes due 2018 (the “2018 Notes”) through a cash tender offer (the “2018 Notes Tender Offer”) and is commencing a tender offer to purchase up to $200 million in aggregate principal amount (the “Maximum 2019 Notes Purchase Amount”) of 7.875% Senior Notes due 2019 (the “2019 Notes” and, together with the 2108 Notes, the “Notes”) through a cash tender offer (the “2019 Notes Tender Offer” and, together with the 2018 Notes Tender Offer, the “Tender Offers”).

In connection with the 2018 Notes Tender Offer, the Company is also soliciting the consents of holders of its 2018 Notes to certain proposed amendments to the indenture governing the 2018 Notes (the “Consent Solicitation”). The primary purpose of the Consent Solicitation and proposed amendments is to eliminate substantially all of the restrictive covenants and certain events of default from the 2018 Notes indenture.

The Tender Offers will expire at midnight Eastern time on July 15, 2014 (the “Expiration Date”). Under the terms of the 2018 Notes Tender Offer, holders of the 2018 Notes who validly tender and do not validly withdraw their 2018 Notes and consents prior to 5:00 p.m. Eastern time on June 30, 2014, such time and date which may be extended (the “Early Tender Date”), will receive the total consideration of $1,063.09 per $1,000 principal amount of 2018 Notes, which is equal to the “tender consideration” of $1,043.09 plus the “early tender payment” of $20.00. Holders of the 2018 Notes who validly tender and do not validly withdraw their 2018 Notes and consents after the Early Tender Date, but prior to the Expiration Date, will receive the tender

consideration, but not the early tender payment. In both cases, holders whose 2018 Notes are purchased in the 2018 Notes Tender Offer will also be paid accrued and unpaid interest from the most recent interest payment date on the 2018 Notes to, but not including, the applicable settlement date.

Under the terms of the 2019 Notes Tender Offer, holders of the 2019 Notes who validly tender and do not validly withdraw their 2019 Notes prior to the Early Tender Date will receive the total consideration of $1,066.29 per $1,000 principal amount of 2019 Notes, which is equal to the “tender consideration” of $1,046.29 plus the “early tender payment” of $20.00. Holders of the 2019 Notes who validly tender and do not validly withdraw their 2019 Notes after the Early Tender Date, but prior to the Expiration Date, will receive the tender consideration, but not the early tender payment. However, if at the Early Tender Date the aggregate principal amount of 2019 Notes accepted for purchase equals or exceeds the Maximum 2019 Notes Purchase Amount, the Company does not expect to accept for payment any additional tenders of 2019 Notes after the Early Tender Date. In such event, proration, if any, shall be determined in accordance with the terms of the 2019 Notes Tender Offer as of the Early Tender Date. If, at the Early Tender Date, the aggregate principal amount of 2019 Notes validly tendered and not validly withdrawn is less than the Maximum 2019 Notes Purchase Amount, the Company expects to accept for payment all 2019 Notes validly tendered and not validly withdrawn at or before the Early Tender Date without proration. In such instance, the Company also expects to accept for payment all 2019 Notes validly tendered after the Early Tender Date and at or before the Expiration Time, up to the Maximum 2019 Notes Purchase Amount, and only 2019 Notes validly tendered after the Early Tender Date and at or before the Expiration Time, to the extent that the aggregate principal amount of all 2019 Notes tendered as of the Expiration Time would exceed the Maximum Purchase Amount, would be subject to proration. In all cases, holders whose 2019 Notes are purchased in the 2019 Notes Tender Offer will also be paid accrued and unpaid interest from the most recent interest payment date on the 2019 Notes to, but not including, the applicable settlement date.

The Tender Offers are contingent upon the satisfaction of certain conditions, including the completion of a private placement offering of new senior notes resulting in gross proceeds to the Company of at least $1 billion. If any of the conditions are not satisfied, West Corporation is not obligated to accept for payment, purchase or pay for, and may delay the acceptance for payment of, any tendered Notes and may even terminate the Tender Offers. Full details of the terms and conditions of the Tender Offers and the Consent Solicitation are included in the Company’s offer to purchase and consent solicitation, dated June 17, 2014.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of any notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
