Sec.  43.103  Types of contract modifications.

    Contract modifications are of the following types:
    (a) Bilateral. A bilateral modification (supplemental agreement) is 
a contract modification that is signed by the contractor and the 
contracting officer. Bilateral modifications are used to--
    (1) Make negotiated equitable adjustments resulting from the 
issuance of a change order;
    (2) Definitize letter contracts; and
    (3) Reflect other agreements of the parties modifying the terms of 
contracts.
    (b) Unilateral. A unilateral modification is a contract modification 
that is signed only by the contracting officer. Unilateral modifications 
are used, for example, to--
    (1) Make administrative changes;
    (2) Issue change orders;
    (3) Make changes authorized by clauses other than a changes clause 
(e.g., Property clause, Options clause, or Suspension of Work clause); 
and
