Integrated MLP -

Competitive Strengths

Increased diversification

Expanded set of acquisition opportunities in both the midstream and upstream sectors

Unique ability to pursue integrated midstream and upstream asset packages

Access to significant drop-down opportunities of upstream NGP portfolio companies on a
negotiated basis

Ability to pursue opportunities to acquire MLP upstream or midstream asset packages at
potentially lower valuations, depending on market conditions

Ability to reap the arbitrage benefits of an MLP in the upstream segment

Ability to leverage upstream and royalty opportunities and relationships into midstream
opportunities

Royalty assets require little corporate overhead and no capital expenditures and allow
Management to focus efforts on operations and organic growth projects
