Initial Registration of Securities. Upon the written request (together with a completed Holder Questionnaire, to the extent required pursuant to Section 3.3.1 hereof) of any Holder of Registrable Securities that were not included in the Initial Shelf Registration (or, if applicable, a Subsequent Shelf Registration) at the time of such request, the Company shall, subject to Section 3.4.2 hereof, use its commercially reasonable efforts to amend the Initial Shelf Registration or Subsequent Shelf Registration, as the case may be, to include the Registrable Securities of such Holder (a “Post-Effective Amendment”); provided, however, that the Company shall not be required to so amend the Initial Shelf Registration or Subsequent Shelf Registration more than once every three (3) calendar months. Subject to the foregoing proviso, within five (5) business days after receiving such a written request pursuant to this Section 2.3.2, the Company shall give written notice of such request to all other Holders of Registrable Securities, and shall include in such Post-Effective Amendment all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) business days after the Company’s giving of such notice; provided that if such Holder Questionnaire is delivered during a Deferral Period (as defined below), the Company shall so inform the Holder delivering such Holder Questionnaire and shall take the actions set forth in this Section 2.3. upon expiration of such Deferral Period in accordance with Section 3.4.2 hereof. For the avoidance of doubt, the Company shall not be required to include in such Post-Effective Amendment any Registrable Securities that are already covered by an existing and effective Registration Statement that may be utilized for the offer and sale of the Registrable Securities requested to be registered.
