3.4 If the purchase and sale of such Core Venture Interests is subject to any prior regulatory approval and the Company acts in a commercially reasonable manner to obtain such regulatory approval (any such regulatory approval to be obtained at the sole cost and expense of the Company), the time period during which such purchase and sale may be consummated shall be extended until the expiration of five (5) Business Days after all such approvals shall have been received, and provided further, that such time period shall not exceed six (6) months from the acceptance of the Purchase Offer without the consent of the ASV Fund, unless the delay results in whole or in part from the failure of the ASV Fund to cooperate in a commercially reasonable manner in obtaining such regulatory approvals.

3.5 If (i) the ASV Fund has not properly received the Purchase Offer for all offered Core Venture Interests or (ii) the Company fails to submit a Purchase Notice in a timely manner, in each case in accordance with Section 3.2, the ASV Fund shall have the right to sell the Core Venture Interests to one or more third parties on any terms and conditions it chooses in accordance with this Agreement.
