We cannot conclude that the landlord’s refusal to consent to the lessee’s sublease constituted wrongful conduct or an omission of a duty by the landlord. According to the terms of Article 11 of the lease, the lessees shall not sublease the premises without the prior written consent of the landlord and the landlord shall not unreasonably or arbitrarily withhold consent to a sublease. Here, the lessees failed to obtain from the landlord written consent prior to entering into the proposed sublease agreement. Nonetheless, the landlord entertained the proposed sublease agreement, with one modification. Under the original sublease agreement tendered to the landlord for his approval, the proposed sublessee was a named corporation, rather than an individual. Because it is the landlord’s standard practice to have an *478individual execute a lease on behalf of a corporate entity, the landlord countered ■with a proposal in conformity with his standard practice. The landlord’s proposal was rejected. We do not find the landlord acted unreasonably or arbitrarily in refusing to consent to the proposed sublease that deviated from his standard business practice.
