(as distinct from suppliers who provide utilities and other goods or services that are not specific to this Agreement) may only be claimed as a Force Majeure if the cause of the subcontractor’s failure to perform was beyond the subcontractor’s reasonable control.

APPENDIX F - DETERMINATION OF RESPECTIVE AMOUNTS OF FEED MATERIAL AND SWU

1.    Determination of the amount of SWU

The relationship between the amount of SWU, the amount of Enriched Product, the amount of Feed Material and the isotopic Assay is:

Q = Qp [V (Np) - V (Nw)] - Qf [V (Nf) - V (Nw)]

where:

V (Nx) = (2 Nx - 1) Ln [Nx/ (1-Nx)]

and:

Qf = Qp (Np - Nw) / (Nf - Nw)

where:

Q    =    amount of SWU to be invoiced

Qp    =    amount of Enriched Product (kgU) Delivered by Supplier

Qf    =    amount of Feed Material (kgU) as UF6 supplied by Customer

Np    =    Enriched Product Assay

Nf    =    Feed Material Assay equal to 0.00711 U-235

Nw    =    Tails Material Assay

V(Nx)    =    function of Nx, the value of which must be calculated for Nx = Np, Nx

=     Nw, Nx = Nf

Ln    =    natural logarithm (base e)

For the application of the above formula the figures shall be treated as follows:

• Intermediate calculation (i.e. V(Np), V(Nf) and V(Nw)) will be rounded to the eighth decimal place.

• The amount of Enriched Product is expressed in kilograms of uranium, rounded to the nearest third decimal place (i.e. to the gram).

F-10

RESTRICTED PROPRIETARY INFORMATION

AREVA XXXXXXXX XX. X00 000 XXX XX 00

USEC CONTRACT NO. EC-SC01-18MI03174

• The amount of Feed Material to be supplied is expressed in kilograms of uranium, rounded to the nearest third decimal place (i.e. to the gram).

• The amount of Feed material used in the formula to calculate the amount of SWU to be invoiced will be rounded to the eighth decimal place.

• Amounts of uranium, either Feed Material or Enriched Product, are obtained by multiplying the measured quantities of corresponding UF6 material (expressed in Kilograms rounded up to the nearest first decimal place for the UF6 weighed in 30B containers and, in the case of UF6 weighed in 48Y containers, rounded up to the nearest integral number) by the measured ratio of uranium content. This ratio is expressed to the nearest fourth decimal place.

• The Enriched Product Assay is expressed in weight fraction and rounded up to the nearest fifth decimal place.

• The amounts of separative work, expressed in SWU, are rounded up to the nearest third decimal (i.e. to the 1/1,000 SWU).

2.    Determination of the amount of Feed Material

The amount of Feed Material to be supplied by Customer for a given amount of Enriched Product is defined by the relationship mentioned in the above Paragraph 1:

Qf = Qp (Np - Nw) / (Nf - Nw)

The Tails Assay used in this formula is the Tails Assay in Customer’s Order.

It is not necessary to take into account any losses which might arise during Enrichment. These losses are for the sole account of Supplier.
