  We study AECs without assuming the amalgamation property in general. We do
assume the disjoint amalgamation property in a specific cardinality lambda and
assume that there is no maximal model in \lambda.
  Under these hypotheses, we prove the following: 1. for every model, M, of
cardinality \lambda, and every \mu>\lambda, we can find a model M^* of
cardinality \mu, extending M. 2.(\lambda,\lambda,\mu)-amalgalmation property:
for every three models M,N,M^* of cardinalities \lambda,\lambda,\mu,
respectively, if M<M^* and M<N then we can amalgamate M^* and N over M.
