MLS Construction LLC asked MD Drilling and Blasting Inc. to do rock drilling and blasting work required for an excavation project. MD had previously done work for MLS but had not been fully paid. MD agreed to do the work if MLS made a significant payment on the balance due. MLS agreed and gave MD a check for $15,000. MD began work and the same day faxed an unsigned written airpayment to MLS. Two weeks later, MD learned that MLS had stopped payment on the check. MD stopped work on the project and sued MLS for breach of contract. MLS argued that the unsigned agreement that MD faxed revoked the original offer, and therefore there was no contract. Did it?
