On March 20, 2018, Dominion Energy Midstream Partners, LP (the Partnership) entered into a $500,000,000 Revolving Credit Agreement (the Credit Facility) with JPMorgan Chase Bank, N.A., as Administrative Agent, Mizuho Bank, Ltd., Bank of America, N.A., The Bank of Nova Scotia and Wells Fargo Bank, N.A., as Syndication Agents, and other lenders named therein.

The Credit Facility will mature in March 2021, unless extended, and bear interest at a variable rate. The Credit Facility can be used by the Partnership to support bank borrowings and the issuance of commercial paper, as well as to support up to $250,000,000 of letters of credit.

The Credit Facility contains covenants that, in the event of default, could result in the acceleration of principal and interest payments; restrictions on distributions related to the Partnership’s equity units, including distributions, redemptions, repurchases, liquidation payments or guarantee payments; and, in some cases, termination of credit commitments unless a waiver of such requirements is agreed to by the lenders. These covenants are customary and not unique to the Credit Facility, and they include:

The Partnership is required to pay annual commitment fees to maintain its access to the Credit Facility. In addition, the Credit Facility contains various terms and conditions that could affect the Partnership’s ability to borrow under the Credit Facility. They include a maximum leverage ratio of 5.00 to 1.00, or 5.50 to 1.00 for a period of time following the acquisition of certain specified assets, subject to adjustments under specified circumstances.

If the Partnership or any of its material subsidiaries, as defined in the Credit Facility, fails to make payment on various debt obligations in excess of $100,000,000, the lenders could require the Partnership to accelerate its repayment of any outstanding borrowings under the Credit Facility, and the lenders could terminate their commitments to lend funds to the Partnership.

The foregoing description of the Credit Facility does not purport to be complete and is qualified in its entirety by reference to the complete text of the Credit Facility, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
