If any portion of the Closing Stock Capital Contribution has not been sold under the 10b5-1 Plan after the Protected Amount has been fully paid under the preceding sentence (any such portion, the “Residual Buyer Common Stock”), then Borrower shall either liquidate the Residual Buyer Common Stock under the 10b5-1 Plan and return the resulting Net Sales Proceeds to Buyer, or return the Residual Buyer Common Stock to Buyer at the times provided for in the 10b5-1 Plan to be held as treasury stock, in each case in accordance with the 10b5-1 Plan, the Amended and Restated Operating Agreement and as allowed under Legal Requirement.

1.4.Resale Registration Rights.

Such Resale Registration Shelf shall include a “final” prospectus, including the information required by Item 507 of Regulation S-K of the Securities Act. Buyer shall use its reasonable best efforts to cause the Resale Registration Shelf and related prospectuses to become effective as promptly as practicable after filing. Buyer shall use its reasonable best efforts to cause such Resale Registration Statement to remain effective under the Securities Act until the earlier of the date all shares comprising the Closing Stock Capital Contribution covered by the Resale Registration Shelf have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant to Rule 144. Buyer shall promptly, and within two (2) business days after Buyer confirms effectiveness of the Resale Registration Shelf with the SEC, notify the Borrower of the effectiveness of the Resale Registration Shelf.

For the sake of clarity, if the Purchase Price is increased, corresponding increase of the principal amount of the Note shall be increased to reflect an original issue discount of 13.33% of the increase in the Purchase Price.
