Read the document to make sure it meets your needs. In particular, check whether the sublease is for a whole or part of a commercial property. If it is a sublease of part check whether the landlord agrees to grant the licence to sublet. The landlord may be entitled to refuse consent without giving a reason. Proceed with the licence only if the landlord is absolutely content with the terms of the sublease.
Remember that if you have any questions you can easily Ask a lawyer.
