NEON agrees that the monthly lease rate for the Network Plus Fibers will be the lowest price per fiber mile under the Term hereof and for the fiber strand count herein charged by NEON for dark fiber leases on the route on which the Network Plus Fibers are located. Should NEON contract to lease dark fiber to a third party at a lower price per fiber mile on the same Term for the same fiber count, then effective as of the commencement of such lease, the lease rate payable hereunder for the relevant Network Plus Fibers shall be lowered to the same price per fiber mile as in said third party contract. NEON and Network Plus shall promptly thereafter execute an appropriate amendment to this Agreement to document such new lease amount. 4.3 INFLATION. On January 1, 1999 and on January 1st of each year thereafter during the Initial Term, the lease rate referred to in Section 4.1 hereof shall be increased by [**] of the percentage increase in the Consumer Price Index for Urban Wage Earners, United States, Base 1982-84 = 100, issued by the Bureau of Labor Statistics of the United States Department of Labor ("CPI-W"), for the immediately preceding calendar year. If the government body issuing the CPI-W ceases to use the 1982-84 average of 100 as the basis for calculation, the CPI-W shall be adjusted to the figure that would have been arrived at had the manner of so calculating the CPI-W not been so changed. If the CPI-W (or a successor or a substitute index) ceases to be published, or ceases to be generally recognized as an index of inflation, the parties hereto shall select and substitute an index which is mutually acceptable, published by a governmental or other disinterested body with appropriate reconciliation of the base of the substituted index with the base of the CPI-W. 4.4 SALES TAX. In addition to the lease rate, as adjusted periodically by Sections 4.2 and 4.3, Network Plus shall be responsible for any and all sales taxes levied on the grant of the IRU for the Network Plus Fiber Network and the lease payments pursuant to Section 4.1. 5.
