9 Our Business Strategies Acquire and produce mature, long lived oil and gas properties which are nearly fully developed and have established, predictable production profiles We have a diversified asset base, geographically, by commodity and within our core operating areas, which reduces single asset risk Remove risk from our portfolio through active commodity and interest rate hedging Grow our stable distributions to unitholders, prudently and over time What We Do: Acquire mature properties Maintain cash flow by investing minimal capital expenditures Grow our production through acquisitions Reduce risk by hedging a significant percentage of production What We Don t Do: Lease large tracts of acreage for development Outspend cash flow to grow production Acquire properties which need significant development capital Take commodity price exposure 9

10 ($mm) How We Spend Capital Disciplined approach to capital spending focus on maintaining cash flow from mature, long lived fields By contrast, resource players invest in growth to support equity valuation The nature of our capital program is inherently less risky due to the lengthy production histories in the fields we operate We grow production primarily through accretive acquisitions of low-risk producing properties, rather than through the drill bit Our capital spending as a percent of 2012A EBITDA is best-in-class 2013E capital budget is $55 million approximately 18% of 2013E Adjusted EBITDA Resource Players Capital Spending vs. Cash Flow E&P MLPs VNR 22% E&P MLPs (1) 66% Resource Players 181% $2,000 $1,825 $1, Adjusted EBITDA 2012 Capex (2) $1,403 $1,200 $1,070 $1,078 $1,062 $932 $800 $731 $670 $400 $511 $453 $512 $346 $231 $50 $296 $153 $198 $68 $268 $137 $0 BRY SFY SD LPI OAS VNR BBEP LGCY EVEP LINE EBITDA / Capex 0.7x 0.5x 0.6x 0.5x 0.5x 4.6x 1.9x 2.9x 1.9x 1.3x 10 Source: Company filings.

11 Our Acquisition Strategy The U.S. has a large inventory of mature oil and natural gas basins which provide significant opportunity for future growth and consolidation Current E&P opportunity set is comprised of an estimated $1.5 trillion of mature properties, which is substantially more than U.S. midstream sector Approximately $40 billion of E&P assets transacted each year since 2007 Vanguard s Acquisition Strategy is to: Acquire mature oil and gas properties with the following characteristics: Stable, long life production with a shallow decline High percentage of proved developed producing reserves Long reserve life Step-out development opportunities for additional growth Efficiently manage the oil and gas assets with focus on maintaining cash flow levels Reduce commodity price and interest rate risk through hedging Return cash flow through distribution payments to unitholders 11

20 20 Financial Overview

21 Disciplined Financial Strategy Maintain conservative capital structure and sufficient liquidity Availability under Revolver as of 2/25/2013 of ~$750 million Target Debt / EBITDA of less than 3.0x Active management of debt levels by periodic access to the equity markets as needed Utilize excess cash flow to reduce revolving debt levels Prudent management of commodity price risk through multi-year hedging program Approximately 90% of expected oil production hedged through 2014 at a FLOOR PRICE of $92.47 per Bbl Approximately 85% of expected natural gas production hedged through the 1H 2017 at $4.62 per MMBtu Acquisition strategy incorporates active hedging component to lock-in anticipated margins Prudently seek acquisitions utilizing our low cost of capital Accretive acquisitions of long life oil and gas assets Maintain a prudent coverage ratio to provide distribution stability and comfortable growth Maintain strong relationships with a diversified bank syndicate Currently have 24 banks in the Revolver 21

22 Risk Mitigation Vanguard seeks to mitigate risk across all facets of its business Drilling and Operational Risk Rate of return disciplined approach to project selection Drill only onshore, proved undeveloped locations Commodity Risk Management seeks to hedge approximately 85% of proved production for a period of 4-5 years Geographic and commodity diversity across the United States Interest Rate Risk Utilize LIBOR swaps to lock-in interest rates for a period of 3-4 years for senior secured debt Issue senior notes which have longer tenures and have fixed rates Acquisition Risk Other Measured and conservative approach to evaluating acquisitions Focus on largely PDP assets with proved upside potential Insurance for property, well control, pollution and general liability 22

23 Hedging Philosophy Hedge commodity prices on estimated production from acquisitions for three to five years upon signing the Purchase and Sale Agreement to protect rate of return from price fluctuations Opportunistic hedging program to extend hedge positions as existing hedges roll off Reduce cash flow volatility and protect distribution levels Primary use of swaps and costless collars, with the addition of three-way collars to provide more upside Interest rate risk also mitigated through hedging 23

24 Locking in Margins Provides Stability Through the use of hedging, Vanguard is able to lock in significant acquisition margins for the foreseeable future, helping to insure distribution stability $ $92.82 $92.27 $93.42 $98.49 $90.00 $80.00 $80.28 $78.85 $84.87 $81.72 $70.00 $67.41 $60.00 $50.00 $40.00 $60.42 $60.48 $43.74 $44.46 $56.12 $44.83 $63.10 $68.50 $48.66 $63.99 $70.50 $51.62 $59.05 $77.93 $62.21 $82.57 $35.14 $39.98 $30.00 $20.00 $10.00 $0.00 $16.68 $16.02 Apache (12/21/07) Dos Hermanos (7/21/08) $11.29 SUN TSH (7/21/09) $17.19 Ward County (11/30/09) $24.32 Parker Creek (5/3/10) $18.75 Encore (11/17/10) $14.85 $14.37 Permian (6/22/11) Permian (8/15/11) $44.99 $6.63 Wyoming (9/1/11) $22.67 Gulf coast (8/31/11) $14.34 $31.21 Montana / N.
