Go with a single, all-inclusive fee like Mark says...
As for how much to charge, most companies follow the percent-of-[perpetual]-license-fee model. This can be a problem for a term license.
For example if you are charging 33% of the perp license fee annually, add 15-25% percentage points for M&S and you are up to something like 50% of the perpetual fee. A price like that defeats the purpose of a term license (lower priced, recurring fees).
I would recommend a more considered approach since a lot of customers are asking what they get for their money. The M (maintenance) part of the fee scales by how many "units" are distributed and the costs of distribuition for you or your customer. The S (support) part of the M&S fee scales by the number and nature of support incidents that you have to field.
Think about how much value the M and the S actually provide and charge accordingly. (BTW, make sure you are clear on what is included in the M piece. Are upgrades in or out?)
If you are clever you can bundle a low but adequate level of M&S with the base product and offer higher levels as a premium offering -- perhaps with a premium version of the product.
