DEBT

Effective March 30, 2012, we amended our revolving credit facility (the "Revolving Credit Facility"). Concurrent with the execution of the amendment, and pursuant to the terms of the original agreement, we exercised our option to increase the total loan availability from $150.0 million to an aggregate of $300.0 million. The amendment allows us to request that the availability be increased up to an aggregate of $450.0 million, subject to receiving increased commitments from the lenders, compared to the original agreement, which allowed an aggregate capacity of $300.0 million. The Revolving Credit Facility is non-recourse to Tesoro, except for TLGP, and is guaranteed by all of our subsidiaries and secured by substantially all of our assets. Borrowings available under the Revolving Credit Facility are up to the total available revolving capacity of the facility. We had $50.0 million of borrowings and $0.3 million in letters of credit outstanding under the Revolving Credit Facility, resulting in a total unused credit availability of $249.7 million or 83% of the borrowing capacity as of March 31, 2012. On April 2, 2012, concurrent with the closing of the Contribution, we borrowed an additional $68.0 million under the Revolving Credit Facility to fund a portion of the consideration for the Martinez Terminal. The Revolving Credit Facility is scheduled to mature on April 25, 2014.

Our Revolving Credit Facility, as of March 31, 2012, was subject to the following expenses and fees:



Credit Facility	30 day Eurodollar (LIBOR) Rate	Eurodollar Margin	Base Rate	Base Rate Margin	Commitment Fee (unused portion)
TLLP Revolving Credit Facility (a)	0.24%	2.50%	3.25%	1.50%	0.50%

____________

(a) We have the option to elect if the borrowings will bear interest at either a base rate plus the base rate margin, or a Eurodollar rate, for the applicable period, plus the Eurodollar margin at the time of the borrowing. Letters of credit outstanding under the Revolving Credit Facility incur fees at the Eurodollar margin rate.
