The exotic hadrons are suppressed because of their relative large masses in comparison to the ordinary mesons and baryons. Hence its contribution to the discrete hadronic mass spectrum is negligible. 

The Fermi-Dirac and Bose-Einstein statistics, respectively, read

The mesonic and baryonic fugacities are given by Λ$_{M}$ = e ( S µ$_{S}$ ) /T and Λ$_{B}$ = e ( µ$_{B}$ + S µ$_{S}$ ) $^{/T}$, respectively, where S = 0 , − 1 etc is the strangeness quantum number. 

The second term ρ$_{(}$$_{II}$$_{)}$ ( T, Λ , m ) on the right hand side of Eq.(119) is the continuous high-lying mass spectrum and corresponds the Hagedorn’s density of states. These states correspond the hadronic bubbles with relatively large hadronic masses and they appear as fireballs just above the highest known hadronic particles those are represented by the dis- crete low-lying mass spectrum. The Hagedorn threshold is estimated to be m ≥ 2 GeV for the non-strange hadrons. In the simplest approximation, the mass of the composite hadron is considered relatively large and the flavor degree of freedom is assumed to main- tain the maximal invariance. Such exotic hadrons (Hagedorns) have no reason to prefer
