  The possibility of the existence of multiquark hadrons made of 4-quark for
mesons and 5-quark for baryons was predicted by Gell-Mann in Ref. [1]. The
renewed interest for the search of exotic pentaquark states was initiated by
the paper by Diakonov, Petrov, and Polyakov in Ref. [2]. The 2003 experimental
reports on the observation of {\Theta^+} pentaquark with a uudd{\bar s} quark
content created a big excitement and many following experiments have reported
its observation [3]. After high-statistics experiments at JLab, which did not
confirm previous claims by the CLAS collaboration, the community concluded that
the {\Theta^+} pentaquark either does not exist at all or has an extremely
small cross section, making it currently unobserved. There were different
review papers on this subject, either questioning the existence of the
{\Theta^+} or attempting to explain the reasons why reaching a conclusion based
on production experiments is challenging [4]. To address the challenge of
minimal 3-body final states, a formation experiment with a projectile kaon beam
is proposed. Below, we discuss how the {\Theta^+} could be observed in the KLp
\to {\Theta^+} \to {K^+}n reaction in the KLF experiment at JLab [5].
