President and Chief Executive Officer
Oil States International, Inc.

Dear Doug,

After careful consideration I have regrettably concluded that, given the time
commitments required to fulfill my obligations to SCF Partners and my role on
the Board of Directors of a number of other public and private companies, I will
be unable to stand for re-election to the Board of Directors of Oil States
International, Inc. ("Oil States") at the upcoming Annual Meeting.

It has been both a privilege and a pleasure to serve on the Board of Oil States
and its predecessor entity for the past eleven years and I wish you and your
colleagues every success in the future.

Sincerely,

/s/ Andrew L. Waite
