Let's redraw it first....#H_3C-CH_2-stackrel("*")CHClCH=CHCH_2CH_3#

Explanation:

The starred carbon is chiral, and can exist in a right-handed or cack-handed geometry. Also the olefin is unsymmetric, and can exist in cis and trans geometry depending on the geometry of the #R# groups about #R_1R_2C=CR_3R_4#....this specifies 4 individual isomers....
