A proxy card to vote your Savings Plan shares and any shares
of restricted stock you own for this year's annual meeting
is scheduled to arrive at your home address within the next
three weeks through the U.S. Mail.  If you have requested
hard copies of the annual report or proxy statement (by e-
mail or fax to David Whitehurst), those will be mailed to
you as well.

Your vote is important.  When your proxy card comes in the
mail, please phone in your vote following the instructions
on your proxy card, or return your marked, signed card to
the independent proxy tabulator, ChaseMellon Shareholder
Services.  A postage-paid return envelope will be provided.
The proxy tabulator will keep your vote confidential.

Thank you for your attention to this important matter.
