This office lease form illustrates the different time lines for different components of rent, additional rents and other charges, thus creating independent commencement and running dates for measurement, and payment. This form also deals with resulting delays in the performance of either party and the impact on all of the defined measurement periods of any delays. Without reference to other facts and documents, the reader will see the benefit of precise complex definitions and also the danger that can result from the casual review of a document that employs the pyramiding of one definition upon another.
