§12A-2-210.
   
   (1) A party may perform his duty through a delegate unless otherwise
   agreed or unless the other party has a substantial interest in having
   his original promisor perform or control the acts required by the
   contract. No delegation of performance relieves the party delegating
   of any duty to perform or any liability for breach.
   
   (2) Unless otherwise agreed all rights of either seller or buyer can
   be assigned except where the assignment would materially change the
   duty of the other party, or increase materially the burden or risk
   imposed on him by his contract, or impair materially his chance of
   obtaining return performance. A right to damages for breach of the
   whole contract or a right arising out of the assignor's due
   performance of his entire obligation can be assigned despite agreement
   otherwise.
   
   (3) Unless the circumstances indicate the contrary a prohibition of
   assignment of "the contract" is to be construed as barring only the
   delegation to the assignee of the assignor's performance.
   
   (4) An assignment of "the contract" or of "all my rights under the
   contract" or an assignment in similar general terms is an assignment
   of rights and unless the language or the circumstances (as in an
   assignment for security) indicate the contrary, it is a delegation of
   performance of the duties of the assignor and its acceptance by the
   assignee constitutes a promise by him to perform those duties. This
   promise is enforceable by either the assignor or the other party to
   the original contract.
   
   (5) The other party may treat any assignment which delegates
   performance as creating reasonable grounds for insecurity and may
   without prejudice to his rights against the assignor demand assurances
   from the assignee (Section 2-609).
