INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE

West Corporation, a Delaware corporation (the “Registrant”) hereby incorporates by reference in this Registration Statement the following documents and information previously filed with the Securities and Exchange Commission (the “Commission”):

(1) The Registrant’s Prospectus filed with the Commission on March 22, 2013 pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the Registrant’s Registration Statement on Form S-1 as amended (Registration No. 333-162292); and

All documents subsequently filed by the Registrant with the Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, after the date of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the respective dates of filing of such documents (such documents, and the documents enumerated above, being hereinafter referred to as “Incorporated Documents”).

ITEM 4. DESCRIPTION OF SECURITIES

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law authorizes and empowers a Delaware corporation to indemnify its directors, officers, employees and agents against liabilities incurred in connection with, and related expenses resulting from, any claim, action or suit brought against any such person as a result of his or her relationship with the corporation, provided that such persons acted in good faith and in a manner such person reasonably believed to be in, and not opposed to, the best interests of the corporation in connection with the acts or events on which such claim, action or suit is based. The finding of either civil or criminal liability on the part of such person in connection with such acts or events is not necessarily determinative of the question of whether such person has met the required standard of conduct and is, accordingly, entitled to be indemnified. The Registrant’s certificate of incorporation provides for indemnification of the Registrant’s directors, officers, employees and agents to the fullest extent permitted under Delaware law. In addition, the Registrant has entered into separate indemnification agreements with the Registrant’s executive officers and directors, which require the Registrant, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service (other than liabilities arising from acts or omissions not in good faith or from willful misconduct). These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of the Registrant’s executive officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability: (i) for any breach of the director’s duty of loyalty to the Registrant or its stockholders; (ii) for acts or omissions not in good faith or which include intentional misconduct or a knowing violation of law; (iii) under Section 174 of the Delaware General Corporation Law (relating to certain unlawful payments of dividend or unlawful stock purchases or redemptions); or (iv) for any transaction from which the director derived an improper personal benefit. The Registrant’s certificate of incorporation includes such a provision.

Section 145(g) of the Delaware General Corporation Law provides that a corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against the person in any such capacity, or arising out of the person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of the law. The Registrant maintains standard policies of insurance under which coverage is provided, subject to the terms and conditions of such policies, (1) to the Registrant’s directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, and (2) to the Registrant with respect to payments which may be made by the Registrant to such officers and directors pursuant to the above indemnification provisions or otherwise as a matter of law.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

Not applicable.

ITEM 8. EXHIBITS

The exhibits accompanying this Registration Statement are listed on the accompanying Exhibit Index.

ITEM 9. UNDERTAKINGS

(a) The Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
