Our Balanced Proposal

1. A Strong Financial Package

2. Atrisco Heritage Preserved

3. Smart Growth for Albuquerque’s West Side

12

A Strong Financial Package

• $315 per share (approx. $250 million total)

• Formation of Atrisco Oil & Gas LLC (AO&G)

• One share of AO&G for each share of Westland common stock owned

• 100% of the rights under Westland’s two existing oil and gas leases

• 50% interest in all future oil, gas and other mineral rights of Westland

• Realization of a centuries-old investment

13

Atrisco

Heritage Preserved

• Formation of the Atrisco Heritage Foundation

• $1 million annually for 100 years

• $2 million provided to Foundation at closing

• Foundation would establish cultural & educational programs

• Foundation board would be comprised primarily of heirs

• Realizing the early vision of the Atrisco ancestors

14

Smart Growth for

Albuquerque’s West Side

• Albuquerque’s recent accolades

• Region’s growth is headed west

• New homes, jobs, entertainment and recreation opportunities will help Albuquerque and Bernalillo County realize its full potential

• Benefits of a single sale

• Benefits of master-planning

15

Shareholder Vote on the Merger

• Proxy process regulated by the Securities & Exchange Commission (SEC)

• Shareholders of both classes of common stock must approve sale by a two-thirds majority

• How to vote:

• Voting by proxy (through the mail)

• Westland proxy statement mailed to shareholders on September 22

• Ballot must be received before November 4 to be counted

• This is the easiest way to ensure your voice will be heard

• Voting in person

• Attend Westland’s shareholder meeting on November 6, 10 a.m., at the Albuquerque Convention Center’s Kiva Auditorium

• Each share of both classes of stock represents one vote

• Votes not cast counted as “no” votes

16

Timeline of Events

* Funds would be distributed promptly following the closing of the sale and upon return of your stock certificates to Mellon. Please wait for Mellon to send you the forms to do so, including forms if you have lost your certificates.

17

What this Means for Westland

• Corporate Structure

• Westland would continue to exist following the merger, but would no longer be owned by Westland’s current shareholders

• Westland would become a subsidiary of a SunCal affiliate

• SunCal executives would become directors of Westland following the merger

• Westland Employees

• SunCal would need a host of local employees with the experience and expertise held by many Westland staffers

• SunCal would continue to employ Westland staff at their current compensation and benefit levels (as of July 19, 2006) for not less than 12 months following the merger

SunCal Proposal
