Deferral of Filing The Company may defer the filing (but not the preparation) of a registration statement required by Section 2.1 until a date not later than sixty (60) days after the Required Filing Date and not more than twice and not more than ninety (90) days in the aggregate in any twelve-month period if (i) the Board of Directors of the Company or a committee of the Board of Directors of the Company determines in good faith that such registration would be materially detrimental to the Company and its stockholders; provided, that the Board of Directors of the Company or such committee, as applicable, shall, in making such determination, take into consideration the benefit to the Company of completing such registration and the reduction of the ownership of Registrable Securities by the Requesting Holder, or (ii) prior to receiving the Demand Request, the Company had determined to effect a registered underwritten public offering of the Company’s securities for the Company’s account and the Company had taken substantial steps (including, but not limited to, selecting a managing underwriter for such offering) and is proceeding with reasonable diligence to effect such offering. A deferral of the filing of a registration statement pursuant to this Section 2.1.6 shall be lifted, and the requested registration statement shall be filed forthwith, if, in the case of a deferral pursuant to clause (i) of the preceding sentence, the negotiations or other activities are disclosed or terminated, or, in the case of a deferral pursuant to clause (ii) of the preceding sentence, the proposed registration for the Company’s account is abandoned. In order to defer the filing of a registration statement pursuant to this Section 2.1.6, the Company shall promptly (but in any event within ten (10) days), upon determining to seek such deferral, deliver to each Requesting Holder a certificate signed by an executive officer of the Company stating that the Company is deferring such filing pursuant to this Section 2.1.6 and a general statement of the reason for such deferral and an approximation of the anticipated delay. Within twenty (20) days after receiving such certificate, the holders of a majority of the Registrable Securities held by the Requesting Holders and for which registration was previously requested may withdraw such Demand Request by giving notice to the Company; if withdrawn, the Demand Request shall be deemed not to have been made for all purposes of this Agreement. The Company may defer the filing of a particular registration statement pursuant to this Section 2.1.6 only once.
