The term loan facility requires no scheduled principal payments or amortization, other than payment in full at maturity.

Borrowings under the Senior Credit Facility bear interest, at CDW?s option, (a) in the case of borrowings denominated in U.S. Dollars, at a rate per annum equal to either (i) an alternate base rate plus an initial margin of 0.125% or (ii) a SOFR-based rate (with a ?SOFR floor? of 0.00%) plus an initial margin of 1.125% and (b) in the case of borrowings denominated in Euro, Sterling, or Canadian Dollars, the Senior Credit Facility provides for term or daily simple benchmark rates (including EURIBOR, SONIA, and Term CORRA, as applicable) plus an applicable margin (and solely with respect to Canadian Dollar Borrowings in Term CORRA, an additional credit spread adjustment of 0.29547% for a one-month interest period or 0.32138% for a three-month interest period).
