Exhibit 4.18

D’ANGELLA BUILDING RIGHT AGREEMENT

English summary of Italian version1

1. Preliminary Note

The building (superficie) right, regulated by article 952 of the Italian Civil Code, is particularly appropriate for the construction of photovoltaic plants, as it allows the grantee of the building right to be owner of the plant whereas the title of the land remains with the grantor.

For the construction and the maintenance of the photovoltaic plant (“PV Plant”) on the land (Municipality of Minervino Murge (BT), sheet 131, parcels 43, 46, 47, 48, 96, 102, 105, 111, 112, 166) (the “Land”), on August 4, 2011 the company Luma Solar S.r.l. entered into a definitive building right agreement. The agreement has been executed in Andria (BT), authenticated by the Notary Salvatore Consolo, Repertorio no. 937, Raccolta no. 638, registered in Barletta and filed with the Conservatoria dei Registri Immobiliari on August 8, 2011.

The above mentioned agreement has been amended by means of a deed authenticated by the Notary Salvatore Consolo, Repertorio no. 968, Raccolta no. 660, registered in Barletta and filed with the Conservatoria dei Registri Immobiliari on September 27, 2011.

Please note that the surface of the Land on which the building right has been set-up is bigger than the one on which the PV Plant has been built (i.e. parcels 46, 47, 48, 166, sheet 131). In order not to have the remaining part of the Land abandoned, Luma Solar S.r.l. entered into a gratuitous lease agreement with the landowners, having as object the portion of Land which has not been used for the construction of the PV Plant (i.e. parcels 43, 96, 102, 105, 111 and 112, sheet 131).

On February 14, 2012 the portion of the Land on which the PV Plant has been built changed its registration number at the Cadastral Land Registry from parcels 46, 47, 48 and 166 to parcels 204 and 198. After that, on February 23, 2012, the PV Plant has been registered in the Cadastral Building Registry with the numbers 204 sub 1 and 198 sub 1.
