If the Title Commitment or Survey shows matters which are not satisfactory to Purchaser, Purchaser shall give Seller written notice thereof within twenty (20) days following the last to be received by Purchaser of the Title Commitment or Survey (but in no event later than 90 days after the Effective Date), and shall state in writing its objection to the same. Failure to give such notice shall constitute approval of the Title Commitment and the Survey. Within twenty (20) days after receipt of such objections, Seller shall have the right, but shall not be obligated, to cure any objections. If Seller shall fail within such twenty (20) day period to cure or commit to cure such objections, then Purchaser may elect, by written notice to Seller, to terminate this Agreement and receive a refund of the Earnest Money and if Purchaser does not so elect, it shall be deemed to have waived all title defects which Seller is unwilling to cure and proceed with Closing hereunder as if said title defects did not exist. Closing may be extended for up to 30 days in order for Seller to cure any title or survey defect which it has committed to cure.
