24. LIENS. Supplier will ensure that its employees, subcontractors, and subcontractor’s employees do not affix any claims or liens upon or against Purchaser’s real or personal property. Supplier will indemnify, defend, and hold Purchaser harmless from these claims and liens. If requested, Supplier will furnish Purchaser with full releases of claims and liens on forms satisfactory to Purchaser. Purchaser may require Supplier to post a bond, at no cost to Purchaser, to remove these claims or liens. Alternatively, Purchaser may discharge or remove these claims or liens by bonding, payment or other means, all of which are chargeable to Supplier along with attorney's fees and costs. In addition to any rights under law, Purchaser may withhold an amount set forth in Exhibit D from each payment it makes to Supplier. Purchaser will pay this amount after (i) Services are completed, the applicable period under law for withholding payments has expired, and no lien or claim has been issued, or (ii) Purchaser is satisfied that all claims have been paid and liens removed. If Purchaser agrees in writing, Supplier may provide an irrevocable standby letter of credit in substitution of Purchaser’s withholding payments. The letter of credit must be satisfactory to Purchaser and name Purchaser as beneficiary.
