§12A-2-609.
   
   (1) A contract for sale imposes an obligation on each party that the
   other's expectation of receiving due performance will not be impaired.
   When reasonable grounds for insecurity arise with respect to the
   performance of either party the other may in writing demand adequate
   assurance of due performance and until he receives such assurance may
   if commercially reasonable suspend any performance for which he has
   not already received the agreed return. (2) Between merchants the
   reasonableness of grounds for insecurity and the adequacy of any
   assurance offered shall be determined according to commercial
   standards.
   
   (3) Acceptance of any improper delivery or payment does not prejudice
   the aggrieved party's right to demand adequate assurance of future
   performance.
   
   (4) After receipt of a justified demand failure to provide within a
   reasonable time not exceeding thirty (30) days such assurance of due
   performance as is adequate under the circumstances of the particular
   case is a repudiation of the contract.
