RE:	Announcement of Hyde Park Merger
ATTACHMENT:	Santa Maria Energy Employee FAQ

Santa Maria Energy Holdings, LLC (“Santa Maria Energy”) has entered into an Agreement and Plan of Merger with Hyde Park Acquisition Corp. II (NASDAQ: HPAC) (“Hyde Park”), a special purpose acquisition corporation.

Hyde Park stockholders and all of Santa Maria Energy’s existing unitholders will receive stock in Santa Maria Energy Corporation (“SMEC”), the resulting parent company in the merger. The shares of SMEC are expected to be listed on the NASDAQ Capital Market.

We expect this transaction to close in the second quarter 2014, following regulatory reviews, all necessary approvals and the satisfaction of other customary closing conditions. Until that time, Santa Maria Energy and Hyde Park will continue to operate as independent companies.

The combined company will continue to be headquartered in Santa Maria. Santa Maria Energy management will continue to oversee the day-to-day operations following the merger.

In fact, there will be few changes except for the fact that SMEC will become a public company. This fact will impose certain additional requirements upon our company; however, for the most part, things will continue unchanged. We have prepared the attached FAQ document for your information.

A press release was issued this morning. Since the release may generate interest from the media and other third parties, it is important for us to speak with one voice. Our “voice” will be Beth Marino.

If you receive any inquiries from the media or other questions from outside Santa Maria Energy, please refer them to Beth Marino. She can be reached by phone at (805) 621-5615 or via email at bmarino@santamariaenergy.com.

The merger represents an important milestone in the ongoing evolution of our company. We will continue to keep you informed as we move forward.

Thank you for all you do to make our company successful.

Sincerely,

David

SANTA MARIA ENERGY EMPLOYEE FAQ

1. What was announced today?

Today, we announced that Santa Maria Energy has entered into a definitive merger agreement with Hyde Park under which we will combine our companies in an all-stock transaction.

2. Who is Hyde Park?

Hyde Park was incorporated under the laws of the State of Delaware on February 24, 2011, as a blank check company, for the purpose of acquiring, through a merger, share exchange, asset acquisition, stock purchase, plan of arrangement, recapitalization, reorganization or similar business combination, one or more operating businesses. On August 7, 2012, Hyde Park completed its initial public offering along with a private placement of its common stock. Substantially all of the proceeds of these offerings are held in trust for the benefit of holders of common stock issued in Hyde Park’s public offering. Hyde Park’s common stock is traded on NASDAQ under the ticker symbol “HPAC.”

3. Why are Santa Maria Energy and Hyde Park combining?

We believe access to the public equity markets will not only enable Santa Maria Energy to execute on the next phase of our long term development plan, but will also position the company to take advantage of future opportunities to accelerate our growth. As we continue to expand, we believe that we will be able to significantly increase our cash flow and profitability over time.

4. What are the terms of the transaction?

Under the terms of the agreement, Hyde Park stockholders and all of Santa Maria Energy’s existing unitholders will receive stock in SMEC, the resulting parent company in the merger.

5. How long before the transaction is completed?

We intend to move forward expeditiously so that we can begin to capture the benefits of this transaction quickly. We expect to receive all necessary regulatory approvals and to complete the transaction by April 30, 2014.

6. Will this announcement affect my work at Santa Maria Energy? Will there be any layoffs?

We do not expect that there will be any layoffs resulting from this transaction. Santa Maria Energy will continue to conduct its business as it has been conducting its business. Until we complete the transaction, Santa Maria Energy and Hyde Park will operate as independent companies.

7. Will there be any changes to employee compensation, benefits and plans?

There will be no change to current Santa Maria Energy employee compensation, benefits and plans, other than with respect to the company’s long-term equity incentive plans. Existing awards under the Santa Maria Energy’s Phantom Equity Plan will be settled in accordance with the terms of the plan and the plan will be cancelled in connection with the closing. Santa Maria Energy’s Profits Interest Plan will also be terminated. In place of these plans, an omnibus equity incentive award plan is expected to be adopted by the new entity, Santa Maria Energy Corporation.

8. After the closing of the transaction, what will the combined company be called and where will it be headquartered?

The combined company will retain the Santa Maria Energy name and will be headquartered in Santa Maria, California. The full legal name of the combined company will be Santa Maria Energy Corporation.

9. Who will lead the combined company?

The current management of Santa Maria Energy will manage the combined company.

10. What are the next steps?
