Mr. Barry Williamson

Webster, Texas 77598-1504

I resign as a Director of the Board of Directors of SPACEHAB

Incorporated, effective immediately (the time is now 10:58 PM Central Time on

the 4th day of December 2007).

There have been recent and multiple board meetings where I have

discussed my disagreements with SPACEHAB s Board and Management, and where I

have dissented with SPACEHAB s Board on multiple issues including financing

strategies, management organization, minute keeping, cost-reduction strategies,

independence, and employee and board compensation and incentive strategies.

SPACEHAB s stakeholders, including its shareholders, debt holders, employees,

and customers, deserve a board that can oversee management s execution of

SPACEHAB s continued reorganization most efficiently and effectively.
