If you should have any questions or concerns about what this acquisition might mean for you, I hope you will feel free to reach out to me or to any of the Shaw leaders with whom you normally interact.

Subject: Shaw to be Acquired by CB&I
Dear Shaw Stakeholder:
This morning, we announced Shaw has signed an agreement to be acquired by CB&I. We believe this is an exciting opportunity and that the transaction will make our combined companies stronger and able to offer more services to our customers.
The combination of Shaw and CB&I will create one of the world’s largest engineering and construction companies focused on the global energy industry. CB&I is a leading engineering, procurement and construction companies and a major process technology licensor. They provide a comprehensive range of solutions to customers in the energy and natural resource industries.
Each company has services that are complementary. Shaw’s leadership position in the power, environmental and infrastructure industries will complement CB&I’s current business and allow both companies to provide extended services and offerings to our customers.
This transition will take some time as there are regulatory and shareholder approvals required. The transaction currently is expected to close during the first calendar quarter of 2013. During that transition period, Shaw will continue to operate in the normal course of business on all projects with the same customer and vendor contacts.
We appreciate your support. Please do not hesitate to contact us with any questions you have during this process.
Sincerely,
J.M Bernhard Jr.
Chairman, President and Chief Executive Officer
