Suspension of Trading At any time after the Registrable Securities are covered by an effective Registration Statement, the Company may deliver to the Holder of such Registrable Securities a certificate (the "Suspension Certificate") approved by the Chief Executive Officer of the Company and signed by an officer of the Company stating that the effectiveness of and sales of Registrable Securities under the Registration Statement would: (i) materially interfere with any transaction that would require the Company to prepare financial statements under the Securities Act that the Company would otherwise not be required to prepare in order to comply with its obligations under the Exchange Act, or (ii) require public disclosure of any transaction of the type discussed in Section 6(d)(i) prior to the time such disclosure might otherwise be required. After the delivery of a Suspension Certificate by Holder of Registrable Securities, the Company may, in its discretion, require such Holder of Registrable Securities to refrain from selling or otherwise transferring or disposing of any Registrable Securities or other Company securities then held by such Holder for a specified period of time that is customary under the circumstances (not to exceed thirty (30) days). Notwithstanding the foregoing sentence, the Company shall be permitted to cause Holder of Registrable Securities to so refrain from selling or otherwise transferring or disposing of any Registrable Securities or other securities of the Company on only one occasion during each twelve (12) consecutive month period that the Registration Statement remains effective. The Company may impose stop transfer instructions to enforce any required agreement of the Holder under this Section 6(d).
