Dear Mike,

I wish to resign my position as Chief Accounting Officer of NGL Energy Holdings, LLC, the general partner of NGL Energy Partners LP, effective November 30, 2015.

I have thoroughly enjoyed my time at NGL, and I thank you for the opportunity to be a part of the team. NGL has accomplished many things over the past four years, and it has been an honor to participate in those accomplishments.

As much as I have enjoyed my tenure at NGL, I believe it is time to begin a new phase of my career, and I plan to start an accounting advisory practice. If it would be helpful, I would be happy to assist in an advisory capacity until NGL has appointed a new Chief Accounting Officer.

Best Regards,

/s/ Jeffrey A. Herbers
