Ann Curry Negotiating Exit From NBC -- Savannah Guthrie a Lock

Ann Curry and NBC are negotiating her exit from "Today" and the hang-up is money ... sources connected with the network tell TMZ.

Our sources say Savannah Guthrie has already made her deal with the network to succeed Ann as co-anchor of "Today," but the snag is the amount of money Ann will get.

As we first reported, Ann gets $10 million a year. She is one year into a 3-year contract, and from what we're hearing NBC does not want to pay her $20 million for the balance of the contract.

Sources tell us Ann wants the full $20 mil and her exit papers. NBC wants to pay her $10 mil and give her a foreign correspondent job. And therein lies the hang-up.

The network could pay her the $20 mil and then prohibit her from working anywhere else for 2 years. But we're told they don't want to shell out that kind of dough, so Ann's lawyer and NBC are haggling.
