In all cases, the End of Contract Period Credit (if any) will be applied against the Customer's PST billing account.

Customers may apply at any time during the Contract Period, subject to the Reconciliation Rules laid out below, to move:

• (i)up to a higher Committed Call Spend but not to a lower Committed Call Spend. Migration from the Customer-based option to the Site-based option is considered a migration to a lower Committed Call Spend;
• (ii)to another BT product of equivalent or greater Contract Period and the same or greater Committed Call Spend.
• (iii)to BT Business One Plan, without reconciliation, provided that the same or greater Committed Call Spend is maintained. In the case of customers moving from a £750 Nomonal Committed Spend customers may take the £500 BT Business One Plan Nominal Committed Spend providing that a £750 Committed Call Spend is maintained or in the case of customers moving from a £10000 Nominal Committed Spend customers may take the £5000 BT Business One Plan Nominal Committed Spend providing that a £10000 Committed Spend is maintained.
• (iv)to BT Business Reward , without reconciliation, provided that the same or greater Committed Call Spend is maintained. In the case of customers moving from the £250Nominal Committed Spend customers may take the £200 BT Business Reward tier. In the case of customers moving from a £750 Nominal Committed Spend customers may take the £500 BT Business Reward tier. In the case of customers moving from a £10000 Nominal Committed Spend customers may take the £5000 BT Business Reward tier.

The original Contract will be terminated and a new Contract Period commenced. The new Contract will be for a full Contract Period and spend under the ceased Contract Period will not count towards the Committed Call Spend for the new Contract Period.

Customers migrating from another Commitment product may take a lower BT Business Plan level, without reconciliation, providing they have met 90% of their pro rata Adjusted Committed Call Spend, but must retain their previous Committed Call Spend amount for a further Contract Period.

BT will allow a 10% tolerance on Customers' Nominal Committed Call Spend to allow for the effect of price reductions during the expired Contract Period. This means that if the Customer's Total Contributory Call Spend is at least 90% of the Nominal Committed Call Spend, no reconciliation charges will apply.

1. If the Customer's Total Contributory Call Spend is less than 90% of £250.00, £500.00 or £750.00 Nominal Committed Call Spend, selected by the Customer, on the Spend Measurement Date, the Customer will be charged on a bill after the Spend Measurement Date as follows:

A reconciliation payment equal to the difference between the Adjusted Nominal Committed Call Spend and their Total Contributory Call Spend.

2. If the Customer terminates BT Business Plan before the end of the Contract Period and before reaching the Committed Call Spend, then the Customer will be billed a reconciliation charge as follows:

A reconciliation payment equal to the difference between the Adjusted Nominal Committed Call Spend and their Total Contributory Call Spend.

This will be invoiced after the cessation of the Contract.

For all contracts with a Spend Measurement Date after 1st April 2004, BT will allow a 10% tolerance on Customers' Nominal Committed Call Spend to allow for the effect of price reductions during the expired Contract Period. This means that if the Customer's Total Contributory Call Spend is at least 90% of the Nominal Committed Call Spend, no reconciliation charges will apply.

In respect of the Migration Rules (i) & (ii) above, a reconciliation charge will apply as follows:

If, on the Spend Measurement Date, the Customer's Total Contributory Call Spend is less than 75% of the pro rata Adjusted Nominal Committed Call Spend, the Customer will be billed for 20% of the difference. For example if a Customer commits to spending £30000.00 per annum and migrates six months into the contract, they should have spent a minimum of £10125.00 (this being 75% of £13500.00 - six months pro rata of the Adjusted Nominal Committed Call Spend). If the Customer has only spent £9000.00 they will be charged 20% of the difference between £9000.00 and £10125.00.

If;

The Customer's Total Contributory Call Spend at the end of any year within the Contract Period is below the Adjusted Nominal `Committed Call Spend' selected by the Customer

Or

the Customer terminates the Contract before the end of the Contract Period and before reaching the Adjusted Nominal Committed Call Spend for any year within the Contract Period. The Customer shall pay a reconciliation payment of 20% of the difference between the Total Contributory Call Spend and the Adjusted Nominal Committed Call Spend. This payment will be invoiced after cessation of the Contract against the Customer's PST billing account.
