WHEREAS, Customer and MCI desire to enter into this Third Amendment for the purpose of amending the Agreement. NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Customer and MCI agree as follows: 1. Paragraph 4(g) is hereby deleted and replaced in its entirety with the following paragraph: 4(g) CNS INTERNATIONAL OUTBOUND RATES.

In addition, the postalized rates in Table 2, may be discounted by (i) the associated maximizer discount in Paragraph 4(l) and 4(m) and (ii) in each month of the Service Term in which Customer's Monthly Usage of MCI Services equals or exceeds Four Hundred Thousand dollars ($400,000) a eight percent (8%) discount ("Latin American discount"). If Customer qualifies for both the maximizer discount and the Latin American discount, Customer will receive an additive discount off the postalized rates in Table 2. For example, if Customer qualifies for the maximizer discount of twenty percent (20%) and the Latin American discount of eight percent (8%), Customer will receive a total discount of twenty-eight percent (28%) off the postalized rates in Table 2. Such discount shall be applied to Customer's monthly usage charges for CNS international dedicated calls terminating in the Latin American countries listed in Table 2 excluding any applicable taxes (and gross receipt taxes) and tax-related surcharges. 3) CNS international calls terminating in the countries listed in Table 3 of Exhibit A will receive the rate per minute in Schedule A for dedicated calls and the rate per minute in Schedule B for non dedicated calls indicated for such country. In addition, the postalized rates in Table 3 may be discounted by (i) the associated maximizer discount in Paragraph 4(l) and 4(m) and (ii) the applicable discount percentage in the table below as determined by Customer's Monthly Usage of MCI Services ("revenue discount"). If Customer qualifies for both the maximizer discount and the revenue discount, Customer will receive an additive discount off the postalized rates in Table 3. For example, if Customer qualifies for the maximizer discount of twenty percent (20%) and the revenue discount of five percent (5%), Customer will receive a total discount of twenty-five (25%) off the postalized rates MCI CONFIDENTIAL 2 in Table 3. Such discount percent shall be applied to Customer's monthly usage charges for CNS international calls terminating in the countries listed in Table 3 excluding any applicable taxes (and gross receipt taxes) and tax-related surcharges.
