Item 1.01              Entry into a Material Definitive Agreement.

On June 28, 2013, NuStar GP Holdings, LLC (“Holdings”) entered into the 364-Day Revolving Credit Agreement among Holdings, as Borrower, JPMorgan Chase Bank, N.A., as Administrative Agent (“Administrative Agent”), SunTrust Bank, as Syndication Agent (“Syndication Agent”), and the lenders party thereto (the “Credit Facility”), to replace the existing 364-Day Revolving Credit Agreement among Holdings, Administrative Agent, Syndication Agent, and the lenders party thereto, dated as of June 29, 2012 (the “Prior Credit Facility”).  The outstanding borrowings of $18,546,128.47 under the Prior Credit Facility were paid off as of June 28, 2013 and all commitments under the Prior Credit Facility were cancelled as of such date.

The Credit Facility matures on June 27, 2014 and has a borrowing capacity of up to $40.0 million, of which up to $10.0 million may be available for letters of credit.  Holdings’ obligations under the Credit Facility are guaranteed by Riverwalk Holdings, LLC (“Riverwalk”), a wholly owned subsidiary of Holdings.  Riverwalk also pledged 1,792,918 NuStar Energy L.P. (“NuStar Energy”) units that it owns to secure its guarantee.  In addition, the Credit Facility contains customary covenants and provisions, including limitations on indebtedness, liens, dispositions of material property, mergers, asset transfers and investing activities.  The rate of interest payable by Holdings to the lenders in respect of loans outstanding under the Credit Facility is (i) with respect to alternate base rate loans, 1.00% plus the alternate base rate then in effect, and (ii) with respect to Eurodollar loans, 2.00% plus the adjusted LIBO rate then in effect.  The facility fee rate payable by Holdings in respect of the lenders commitments (whether used or unused) is 0.30% of such commitments.  The fronting fee rate payable by Holdings in respect of any letters of credit issued is 0.25% of such letters of credit.

The Credit Facility provides that Holdings will be in compliance with the consolidated debt coverage ratio as long as NuStar Energy maintains, as of the last day of any fiscal quarter, a consolidated debt coverage ratio not to exceed 5.00 to 1.00; provided, that, if at any time NuStar Energy has consummated one or more acquisitions within the two most recently completed fiscal quarters for an aggregate of at least $50.0 million, then, for the two rolling periods the last day of which immediately follows the date on which such acquisition is consummated, the numerator of the maximum consolidated debt coverage ratio otherwise permitted above shall be increased by 0.50 (not to exceed 5.50 to 1.00 for such rolling periods).

Holdings is also required to receive cash distributions of at least $12.5 million in respect of its ownership interests in NuStar Energy for the preceding four fiscal quarters ending on the last day of each fiscal quarter. Holdings indirectly owns the 2% general partner interest, all of the incentive distribution rights and an approximate 12.8% limited partner interest in NuStar Energy.

The Credit Facility contains customary events of default, including a “change in control” provision, which could result in the acceleration of all amounts and cancellation of all commitments outstanding under the Credit Facility. Further, the Credit Facility imposes certain restrictions on defaulting lenders, including: (a) the termination of fee accrual on unfunded portions of such defaulting lender’s commitment, (b) the exclusion of the defaulting lender’s commitment and credit exposure in a determination of whether lenders may take action pursuant to the Credit Facility and (c) potential reallocation or cash collateralization of the defaulting lender’s outstanding letter of credit exposure.

A copy of the Credit Facility is filed as Exhibit 10.01 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 2.03                                           Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The description of the Credit Facility set forth above under Item 1.01 above is incorporated by reference into this Item 2.03.
