If a claim for a lien under a recorded notice of lien is not paid or assumed at the closing of a sale, lease, or mortgage of the commercial real estate interest subject to the lien and would prevent the closing of the transaction or conveyance or if a claim for a lien under a recorded notice of lien does not survive the closing, any person named in the notice of lien as obligated to pay the commission shall, on the date of the closing:
(1) establish an escrow account from any net proceeds of the transaction or conveyance in an amount equal to the amount sufficient to satisfy the lien plus 15 percent of that amount; or
(2) file a bond to indemnify against the lien as provided by Subchapter G.
