Opportunity Overview

On November 27, 2013, Santa Maria Energy entered into a merger agreement (the “Merger”) with Hyde Park

Acquisition Corp. II, a special purpose acquisition company (NASDAQ: HPAC)

The transaction is expected to close on or prior to April 30, 2014

Transaction is a tax-free reorganization under IRC Section 351 to Santa Maria Energy and HPAC

The Company is pursuing a private capital raise (the “Private Equity Financing”) of ~$71 to $110 million in conjunction with the proposed Merger

The Company is well capitalized on a pro forma basis allowing for the successful execution of its drilling program

Santa Maria Energy, headquartered in Santa Maria, California, is a private E&P operating company

Funded by Kayne Anderson in 2008 for $50 million and accrued dividend and guarantee fee in excess of $18 million

Only California pure oil-play C-corp

The Company is actively engaged in developing low-risk opportunities in the Santa Maria Basin within the Diatomite reservoir and Monterey formation

History in California

Diatomite Monterey

Diatomite formations in California contain 12-80 billion barrels of original OOIP(1) High porosity, high oil saturations, average thickness and high Bbls/acre-ft make it a tremendous oil resource

Oil-impregnated Diatomite reservoir rock is known to exist in both the San Joaquin and Santa Maria Basins

1983: Shell/Chevron/Mobil developed Diatomite with vertical sand-propped frac’d wells in the San Joaquin Basin at Lost Hills and Belridge fields As the Diatomite became more understood, development emphasis centered around compaction management, infill drilling and waterflood optimization

500 BBbls of OOIP in California(2)

Formation extends from Northern CA to Los Angeles County and over to the outlying islands off the coast of California

Has approximately 15.4 BBbls of technically recoverable oil(3) Oil has been extracted since the end of the 19th century

A total of approximately 28 BBbls produced to date in California from all sources

Santa Maria Basin History

1903: Union Oil discovered Monterey fractured play at Orcutt Field

1901-1942: Multiple Monterey fields developed in Santa Maria Basin

1980-1990s: Oil price collapse led to an abandonment of future development in Santa Maria Basin as most drilling became uneconomic with precedent recovery techniques

1995: Operators such as Freeport McMoran, TRC, and Chevron initiate steam flood of Diatomite reservoirs

Encouraging Offset Operator Results

As the offset operator, Pacific Coast

Energy Corporation’s (“PCEC”) success in Orcutt field serves as a good proxy for Santa Maria Energy’s expected results

PCEC is the operating entity associated with the publicly traded royalty trust Pacific Coast Oil Trust (NYSE: ROYT)

Santa Maria Energy’s pilot is similar to PCEC’s original wells in average oil rate, size and SOR

SOR has been declining for PCEC

PCEC’s most recent wells are performing the best

Pod 2000, 16 wells, averaged 50 Bopd in August 2013

Average oil rate per well increased in pod 2000 after new wells were added

Diatomite Production Technique

Cyclic steam injection is the primary method for hydrocarbon recovery from Diatomite reservoirs

Santa Maria Energy’s process avoids fracturing the rock

Cycle consists of 3 phases: Injection phase (3-5 days):

Approximately 1,500 Bbls cold water equivalent Steam heats oil which lowers viscosity for easier flow Formation pressure increases Soak phase (1-3 days): Well closed in Steam condenses to water which is absorbed by the rock and oil is simultaneously desorbed Production phase (7-21 days): Well is opened and oil is allowed to produce Increased pressure and remaining steam lifts the oil out of the well Oil production begins to decrease as the energy put into the reservoir declines

Real-time reservoir pressure control, steam management, data collection and analysis are integral to the process

Sequential completions are used to process each interval of the reservoir

The cycle is repeated on average 150 times through the life of each well

Steam Injection Process

Santa Maria Energy is Committed to Planned Infrastructure Expansion

8 mile tertiary treated water pipeline

Recycled wastewater from local sanitation district for steam generation; aiding county in wastewater disposal problems

2 mile oil sales pipeline that connects to existing Phillips 66 oil pipeline

Orcutt Monterey Overview and Highlights

Overview

Orcutt field discovery well drilled in 1903

Estimated to have produced only 7.7% of OOIP

Field mostly developed in the early 1910’s

Over 50 well penetrations still producing

Most with only “driller logs”

A significant volume of oil remains to be recovered by utilizing an improved reservoir model and modern horizontal drilling and production techniques

Initial drilling programs and concepts

Redevelop field with up to 41 horizontal wells

Plan wells above - 2,600 feet VSS

Plan wells to drain - 150250 feet of reservoir Development includes the use of existing well locations and well bores thereby streamlining the regulatory process

Facility expansion/upgrades in 2014 will support 14 wells

Complete seismic program in 2014 to develop additional well control

3 wells have been plugged back and are ready to redrill

Development offers excellent repeatability and superior returns (1) on a per well basis with BTAX IRRs in excess of 100%

Santa Maria Valley Monterey Overview and Highlights

Overview

Santa Maria Valley field is one of the larger oil accumulations in the Santa Maria Basin Estimated to have produced only 4.6% of OOIP

Field mostly abandoned in the early 1990’s

Over 400 well penetrations Most with rudimentary logs

At time of abandonment the field was producing ~650 BOPD with the average well producing between 5 – 10 Bopd

A significant volume of oil is believed available for recovery by utilizing an improved reservoir model and modern horizontal drilling and production techniques

Own 60% WI and an approximate 50% NRI

Drilling programs and concepts

Redevelop field with at least 69 horizontal wells Use structure maps to define well bore course Use thickness maps and 150 foot thickness cut-off to define horizontal targets Plan wells above - 3,000 feet VSS

Plan wells to drain 150 - 250 feet of reservoir

Utilize “drill islands” and production facility locations

Northwest Casmalia Diatomite Overview and Highlights

Overview

The Northwest Casmalia site, a 4.2 mile Diatomite trend, will likely prove to be an extension of the 100 year old Casmalia field Santa Maria Energy has delineated oil in Northwest Casmalia ranging from 4 to 17 API gravity oil

The 4.2 mile trend is located within the Santa Maria Energy 8,800 acre land position

Demonstrations of oil saturation along the trend are: Core holes drilled by Unocal, Gulf Minerals, and Pacific Oil 16 wells drilled by Santa Maria Energy in 2006

5 Year Plan

Pre-drilling activities starting in 8/14 Drill delineation wells across entire trend starting in 8/14 Further develop pilot area and facilities established in 2006 1st Q 2014 – Begin internal regulatory preparation for initial commercial development 1/17 – Anticipated project approval

Reservoir Characterizations

Diatomite

Diatomite is an unconventional reservoir

Unique rock properties control Diatomite productivity

Composed from skeletons of prehistoric marine microorganisms (40-70 million per cubic inch) and found at shallow depths,

Water-wet and has an affinity to imbibe water which helps mobilize the oil

Depth: up to 2,200 feet

Porosity: 50% – 70%

Initial permeability: 6-14 millidarcies (calculated from primary production)

Initial oil saturation: 45% – 60%

Monterey

Produces oil and natural gas, is primarily composed of oil and a number of other substances

Largely a shale but can include sands, dolomite, mud deposits and highly dense chert, a rock consisting of microcrystalline quartz

Considered a source rock

Can recognize productivity on electric log Depth: 2,500 – 12,000 feet Thickness: 500 – 3,500 feet Porosity 5% – 30% Permeability: <0.0001 – 4 millidarcies TOC: 0.1% – 15.6%
