Term Plan Access Charge Promotion

Beginning April 21, 1995 and ending March 31, 1997, MCI WORLDCOM will offer the following promotion to new and existing customers who allow MCI WORLDCOM to provision their dedicated local access service. Specifically, MCI WORLDCOM will waive all Access Coordination charges for the duration of a Customer's Access Pricing Plan (APP) or Combined Service and Access Plans (CSAP) commitment. To qualify, the local access service must consist of dedicated local leased line services provisioned by available MCI WORLDCOM-owned facilities, and must be ordered no later than June 30, 1996, installed prior to March 31, 1997, and subscribed to under an APP or CSAP.

MCI Vision RPP Promotion

Beginning February 1, 1995 and ending October 14, 1995, MCI WORLDCOM will offer the following promotion to existing customers of Metered Use Service Option Q (MCI Vision), or to new customers of MCI Vision who enroll in this promotion between March 1, 1995, and October 14, 1995. In order to receive the benefits of this promotion, the customer: 1) must be enrolled in an MCI Vision term plan or MCI Customized Business Program; 2) must terminate the existing term plan or program pursuant to the terms and conditions of the Early Termination Charges of the respective plans, as described in Section C‑3.18365 or the Cancellation or Discontinuance Without Liability, as described in Sections C‑3.183751 and C‑3.1841; and 3) must enroll in a new MCI Vision Value Insurance Plan Plus (MCI Vision VIP Plus) or the MCI Vision Worldwide Program with a term and volume commitment equal to, or greater than, the customer's existing plan. The new term plan will begin on the day after the expiration date of the existing term plan. MCI Vision non‑term plan customers may also receive the benefits of this promotion. All customers must enroll in an MCI Vision VIP Plus or MCI Vision Worldwide plan with a start date between February 15, 1995 and October 15, 1995, in order to receive the benefits of this promotion.

For the duration of the plan, MCI Vision customers will be charged the applicable rates and given the discounts specified below. All other terms and conditions of the term plan will apply. At any time during the term of the plan, customers may elect to leave the promotion and revert to MCI Vision standard tariffed rates and discounts; however, the customer must maintain an equal or greater term and volume commitment. Once the customer reverts to MCI Vision standard tariffed term plan rates and discounts, it will not be eligible to receive the benefits of this promotion. Upon expiration of the new term plan, the customer will revert to the prevailing tariffed rates and discounts at that time.

Once enrolled in this promotion, a customer may increase its volume commitment, but not its term commitment, and it remains eligible to receive the discounts that it received upon enrollment in this promotion. Customers are not eligible for any other MCI Vision promotions except that they may receive the benefits of installation and fee waivers, the MCI PIC Change Promotion and the MCI Vision PIC Change Credit Promotion. The benefits of this promotion are not available in connection with SCAs, as described in Section C‑16. Standard monthly recurring charges, non-recurring charges, access charges, Dedicated Leased Line Service rates, and Operator Service rates apply for all customers enrolled in this promotion. Qualified Affinity Member Groups who enroll in this promotional plan will not receive the benefits of the Affinity Member Group discounts associated with MCI Vision VIP Plus and MCI Vision Worldwide. A customer enrolled in the MCI Vision Worldwide for Latin America or the MCI Vision Worldwide for Europe option may not receive the benefits of this promotion.

This discount is calculated and applied at the location level. International and Directory Assistance calls are excluded from this discount.

International Optimizer Discount: A discount of 10 percent will be applied to all international outbound Vision calls made during the peak rate period which are made to the single country with the highest total usage (in dollars) for the period for which a bill is being calculated.
